The document presents a study on the dynamic analysis of parabolic cylindrical shell structures with varying parameters like thickness, radius, and skew angle. A parametric study is conducted on cylindrical shell models with different lengths, radii, and thicknesses using the SAP2000 software. The behavior of the shells is evaluated based on parameters like stresses, strains, deflections under different loading conditions. The results of the analysis for varying thickness and radius while keeping other dimensions constant are presented through tables and graphs. It is observed that the longitudinal stresses play a major role in resisting loads compared to other stresses. Stresses decrease with increasing skew angle but transverse stresses and moments increase. The study concludes that shell behavior is dependent on parameters like rise, thickness, and

Characterization of al sic metal matrix by stir-castingIAEME Publication
This document summarizes research on the production and characterization of Aluminum-Silicon Carbide (AlSiC) metal matrix composites fabricated using stir casting. Samples of AlSiC composites with 5-30% SiC by weight were produced. Testing showed that hardness and impact strength increased with higher SiC content, with maximum values at 25% SiC. Microstructure examination found increasing homogeneous dispersion of SiC particles with methods using mechanical stirring during production. The study demonstrated that stir casting can produce AlSiC composites with improved mechanical properties for engineering applications.

Studies on geometrical featured metallic shell structures for inward inversionIAEME Publication
This document summarizes research on the inward inversion of metallic shell structures with various geometric features for energy absorption applications. Experiments were conducted using an Instron testing machine to apply loads and measure force-displacement responses for aluminum shell samples with different shapes, wall thicknesses, steps, and curvatures. Finite element simulations of the inversion process matched well with experimental force-displacement graphs and stress distributions. Key findings include frusta with 6-7 degree angles absorbed the most energy, while steps and uneven curvatures reduced energy absorption and caused unstable force responses. Thicker shells and straighter top portions also improved energy absorption performance during inversion.
DRY TURNING OF AUSTENITIC STAINLESS STEEL (316L) USING CVD COATED TOOLAM Publications
Austenitic Stainless steel (316L) is a low carbon high chromium containing high alloy steel, it has a good number of application because of its high strength, high ductility and corrosion resistance. It is used in jet engine parts, heat exchanger application and pharmaceutical application. It is compatible in cryogenic temperature to red hot temperature. The paper presents an experimental investigation on different parameters which affect the cutting process and also cause significant effect on the chip formation in machining of Austenitic Stainless steel (316L). In this study, experiments were conducted on Austenitic Stainless steel (316L) at different cutting speed, feed and depth of cut and the effect of different influential parameters on the process of chip formation has been studied subsequently. Quality characteristic of machined item is depending much on material behaviour during machining. Present experimental analysis on machining has been performed by implementing Von Mises stress evaluation employing true stress-true strain behaviour of the materials under consideration. Experimental true stress-true strain plot was required to find out the strength coefficient and strain hardening exponent of the material and using the same, Von Mises stress was estimated by using material property consideration. Experimental study on machining was performed on austenitic stainless steel (316L) to know the trend of variation of chip thickness, shear angle, Von Mises stress and total work done with respect to cutting velocity. From the study it showed that austenitic stainless steel gets work hardened at higher cutting speed. Therefore this type of material can be machined at lower cutting speed only.

The document analyzes friction stir welding tools with various threaded pin profiles. Three tool pin profiles are modeled in CATIA and analyzed using ANSYS: cylindrical, frustum, and conical pins with threads. The stress distributions and displacement vectors in the pins are obtained for different rotational speeds and temperatures. The results show that the cylindrical pin profile experiences the lowest stress levels and displacement compared to the other profiles. Increasing rotational speed does not significantly affect the stress, while higher temperatures generally increase stress across all pin profiles. The cylindrical pin profile is determined to be preferable for withstanding loads during friction stir welding.
In a multi-storied building, the beam-column joint is one of the most critical regions. Usually the beam-column joint was considered as rigid frames. Various researchers over the past years indicated that the joint is not rigid. Now it is also stated that instead of the failure in beam and column, failure can also occur in joint hence joint must be considered as a structural member. The Indian standards define a joint as the portion of the column within the depth of the deepest beam that frames into the column. In framed structures the bending moment and shear forces are maximum at the junction area. So, beam column joint is one of the failure zones. Among the beam column joints, the exterior joint is more critical. The exterior beam column joint have been a study for about 30 years since now. Still there are many more to be understood. In the present work a building is designed in STAAD. Pro V8i and an exterior beam column joint is considered. This joint is modelled in NX CAD and imported to ANSYS to analyse it to derive the shear stress and the corresponding deformation.

Probabilistic Design Hollow of Airfoil Wing by Using Finite Element MethodIJERA Editor
This document presents a probabilistic finite element analysis of the bending stress in a hollow NACA0012 airfoil composite wing. The analysis varies key geometric parameters, material properties, composite layer properties, and applied load within realistic ranges using Monte Carlo simulation. Scatter plots show the effects of each input parameter on the bending stress output. The results identify that chord length, ply thickness, orientation angle, Young's modulus in the XX direction, and shear modulus in XY have the most significant effects on bending stress, while other inputs have less influence. This probabilistic analysis can help determine robust input parameters and limits for optimization of the airfoil wing design.
Mechanism of Fracture in Friction Stir Processed Aluminium AlloyDr. Amarjeet Singh
Aluminium alloys are used for important
applications in reducing the weight of the component and
structure particularly associated with transport, marine,
and aerospace fields. Grain refinement by scandium (Sc)
addition can eliminate the casting defects and increase the
resistance to hot tearing for high strength aluminium alloys.
FSP for cast aluminium alloys have been focused and it has
great advantages including solid state microstructural
evolution, altering mechanical properties by optimizing
process parameters. These parameters are tool rotational
speeds (720, and 1000 rpm), traverse speeds (80, and 70
mm/min), and axial compressive force at 15 kN, etc. The
mechanical properties had been evaluated on FSPed
aluminium alloy with different microstructural conditions.
Fracture properties of aluminium alloys are very important
for industrial applications. Tensile and fracture toughness
properties were correlated to microstructural and
fractographic features of the aluminium alloys need to
explore their essential failure mechanisms.
Abstract:The worm & worm wheel is used in gear box of Winch machine for lifting sand bucket. During working worm wheel fails due to load coming on the teeth. The failure is due to stress concentration. The crack appears at central thickness of tooth. Hence the tooth breaks at the central thickness. The failure of wheel occurs within period of about 20 days. So the company has to replace the worm wheel which is not cost effective. The stress calculation of worm wheel at tooth thickness is a three dimensional problem. This paper represents the review of analysis of stress pattern by using 3D Photo elasticity techniques & FEA technique.

The Effect of Direct- and Cross-Rolling on Mechanical Properties and Microstr...Kaveh Rahimi Mamaghani
Severely deformed commercial pure aluminum sheets by constrained groove pressing are direct and crossrolled.
The grain size evolution and dislocation density during rolling are studied using Williamson-Hall
analysis on x-ray diffraction patterns of the deformed samples. These results and optical microscopy
observations show that subsequent direct or cross-rolling of constrained groove pressed aluminum can
produce elongated fine grains. The minimum crystallite size is achieved after cross-rolling of constrained
groove pressed samples. By direct-rolling or cross-rolling of annealed sheet, the maximum intensity in x-ray
diffraction patterns remains on (200) like annealed aluminum but direct-rolling or cross-rolling of constrained
groove pressed sheets changes the maximum intensity from (111) for constrained groove pressed
sheets to (220). Also, mechanical properties are studied using tensile test and hardness measurement. The
results show that cross-rolling on constrained groove pressed samples is more effective than direct-rolling in
mechanical properties improvement.
Cutting force and surface roughness in cryogenic machining of elastomerIAEME Publication
This document summarizes research on cryogenic machining of elastomers. Experiments were conducted to analyze the effects of rake angle, cutting speed, and feed rate on cutting force and surface roughness under ambient and cryogenic conditions. The results showed that cutting forces were higher for cryogenic machining but decreased with increasing rake angle. Cryogenic machining produced significantly lower surface roughness than ambient machining, especially at high rake angles and cutting speeds, due to increased material rigidity at lower temperatures.

IRJET- Modeling and Design Analysis of Die Profile of Extrusion of Square...IRJET Journal
This document discusses the modeling and design analysis of the die profile for extruding a square cross-section from a round billet using a non-linear converging die. Finite element method (FEM) simulations were conducted using DEFORM-3D software to analyze extrusion loads for different die profiles and process parameters. Experimental extrusion tests were also performed on lead and aluminum to validate the FEM results and investigate the effects of lubrication and splitting the workpiece. The non-linear cosine die profile was found to require less extrusion load than a linear die profile under the same conditions.
The document presents an experimental study on the effect of rivets on damping in jointed structures. Specifically, it investigates how the damping ratio of cantilever beams made of mild steel is affected by increasing the number of connecting rivets. Both experimental and finite element analysis are conducted. In the experiments, specimens of different thickness ratios and rivet configurations are tested using an FFT analyzer to determine their natural frequencies and damping ratios. The finite element models are developed in ANSYS and harmonic analysis is performed. The results show that the damping capacity increases substantially with more rivets, due to greater friction at the interfaces. Both experimental and FEA results are found to be in good agreement.

This study compared the manual widening of root canals with different degrees of curvature using Kerr file needles made of stainless steel or nickel-titanium alloy versus ProTaper cutters. The root canals were simulated with curvatures of 30, 45, 60, and 90 degrees and radii of 3, 4, and 5 mm based on 46 real patient cases. The results showed that Kerr files made of steel produced the greatest deviations from the natural root canal trajectory, while nickel-titanium alloy and ProTaper instruments produced less deviation. The highest modifications occurred with rigid instrumentation of extreme anatomies. Mathematically, nickel-titanium instruments, especially ProTaper, were shown to achieve more uniform widening of curved root
MODELING, ANALYZING AND SAFETY ASPECTS OF TORSION AND NOISE EFFECTS ON ROUND ...msejjournal
Each material has its own effect and behavior on external impacts like heat, force, tension, compression, torsion etc. It is important to study and analyze these behaviors before selecting a material for an engineering application in the design aspects itself. If predicted values analyzed by both mathematical and software are available it is easy to get the reliable details in the pre design itself. By this one can ensure the safety of the component and the system also. In this investigation, the effects of torsional loads on mild steel
round shafts with various diameters and lengths have been analyzed. The additional effects like angle of rotation, rpm and duration also considered to find the optimum predicted value. The data observed by various experiments are analyzed by design of experiments especially by response surface methodology. Minitab software is used for canalization. The data are tabulated and kept for future reference. Noise effect
due to the gradual torsional load performed in the gear box and other rotating components is also studied for healthy working environment. The nature and characteristics of material also be explained by this noise analysis.

Mechanical characterization of different orientation of glass fibre reinforce...eSAT Journals
Abstract The purpose of this study is to evaluation of the mechanical characterisation such as tensile, compression and bending test and to conduct wear test. This study focus on preparation and testing of Polyester resin using glass fibre for different orientation. The Mechanical properties of the polyester changes gradually by changing the layers of fibres and for different orientation of glass fibre the property differs. The laminate is prepared of size 300*300*4mm size and specimens are prepared as per ASTM standard, different layers of glass fibres are one, two and three layers and the orientation of glass fibre is 30o, 60o, and 90o. The glass fibre used is in fabric form. From the results which were obtained we can observed that three layers glass fibre for 90o orientation has improved tensile strength and the compressive strength is found to be more for 600orientation of glass fibre. And the wear rate is also less for three layer of glass fibre for 900 orientations. Keywords: Glass Fibre/Polyesters Composites, Mechanical Characterisation of Polyester, Orientation of Glass Fibre
Analysis of Parabolic Shell by Different Models Using Software SAP 2000ijtsrd
The shell structure consists of a thin reinforced concrete shell without the use of internal columns to create an internal opening., parabolic or spherical cross section. On the other hand, warehouses and playgrounds are conventional concrete frame structures, on the other hand, they can be difficult to design as the exact shape required for the stability of the structure depends on the material used, the dimensions of the enclosure, external or internal loads and other chamfers.. .. Thus, by changing the shell parameter, the performance of the shell will also change. The main goal of this work is to parametrically analyze different designs of cylindrical shells of different lengths in order to analyze two different lengths of taken cylindrical shells, and then change two parameters, first the radius and then the thickness, based on the radii. and the difference in thickness for the same width, length and material of the frame, we will evaluate the behavior of the frame for different models.

Analysis and Modeling of Steel Square Hollow Beam to Square Hollow Column Jointijtsrd
Most of the steel structures in India are made of conventional steel sections such as angle, channel and beam sections . However, new hollow steel sections such as square and rectangular hollow sections are gaining popularity in recent steel constructions due to a number of advantages such as its higher strength to weight ratio, better fire resistance properties, higher radius of gyration, lesser surface area, etc. This type of hollow sections can save cost up to 30 to 50 over the conventional steel sections. But unlike the conventional steel sections these hollow sections do not have standard connection details available in design code or in published literature. To overcome this problem the objective of the present study was identified to develop a suitable and economic connection detail between two square hollow sections which should be capable of transmitting forces smoothly and easy to be fabricated To achieve the above objective, a square hollow beam to square hollow column connection was selected and modeled in commercial finite element software ABAQUS. This model was analyzed for nonlinear static pushover analysis considering a number of connection details. Following four alternative scheme of connection details were selected for this study i using end plate, ii using angle section, iii using channel sections, and iv using collar plates. The base model rectangular hollow beam welded to one face of the rectangular hollow column is also studied for reference. The performance of the selected connection details are compared and the best performing connection details is recommended for rectangular hollow beam to rectangular hollow column joints. The result shows that the load carrying capacity of the joint and the maximum deformation capacity is highly sensitive to the type of connection used. Also, the location of formation of plastic hinges in the structure which can be at joint or at beam depends highly on the type of connection used.

Parametric Evaluation of Tall Structure with Various Lateral Load Resisting S...ijtsrd
The high rise buildings are majorly suffering with seismic forces, it can be found out by displacement parameter. The more the displacement the lesser will be the stiffness of the structure. The static analysis is having higher displacement value than response spectrum analysis. The increase in percentage is about 17 . This will increase the construction cost due to increase in stiffness. The base shear value increases with increase in weight of the structure. However, the diagrid structure seems to be having lesser weight than all other models. From the overall analysis it is proved that, diagrid structure is very much effective than any other structure. However, in case of constraint in providing diagrid due to its architectural features, the outrigger system with bracing will be very much effective.

1) FSP was used to refine the grain structure of AA6061, decreasing the average grain size by 70% compared to the untreated metal.
2) Hardness testing found that hardness increased with additional FSP passes, with hardness up to 1.75 times higher than untreated areas after 4 passes.
3) Microstructural analysis found that FSP effectively refined the grain structure through severe plastic deformation during processing, leading to improved mechanical properties like increased hardness.
Probabilistic Design Hollow of Airfoil Wing by Using Finite Element MethodIJERA Editor
This document presents a probabilistic finite element analysis of the bending stress in a hollow NACA0012 airfoil composite wing. The analysis varies key geometric parameters, material properties, composite layer properties, and applied load within realistic ranges using Monte Carlo simulation. Scatter plots show the effects of each input parameter on the bending stress output. The results identify that chord length, ply thickness, orientation angle, Young's modulus in the XX direction, and shear modulus in XY have the most significant effects on bending stress, while other inputs have less influence. This probabilistic analysis can help determine robust input parameters and limits for optimization of the airfoil wing design.
Mechanism of Fracture in Friction Stir Processed Aluminium AlloyDr. Amarjeet Singh
Aluminium alloys are used for important
applications in reducing the weight of the component and
structure particularly associated with transport, marine,
and aerospace fields. Grain refinement by scandium (Sc)
addition can eliminate the casting defects and increase the
resistance to hot tearing for high strength aluminium alloys.
FSP for cast aluminium alloys have been focused and it has
great advantages including solid state microstructural
evolution, altering mechanical properties by optimizing
process parameters. These parameters are tool rotational
speeds (720, and 1000 rpm), traverse speeds (80, and 70
mm/min), and axial compressive force at 15 kN, etc. The
mechanical properties had been evaluated on FSPed
aluminium alloy with different microstructural conditions.
Fracture properties of aluminium alloys are very important
for industrial applications. Tensile and fracture toughness
properties were correlated to microstructural and
fractographic features of the aluminium alloys need to
explore their essential failure mechanisms.
Abstract:The worm & worm wheel is used in gear box of Winch machine for lifting sand bucket. During working worm wheel fails due to load coming on the teeth. The failure is due to stress concentration. The crack appears at central thickness of tooth. Hence the tooth breaks at the central thickness. The failure of wheel occurs within period of about 20 days. So the company has to replace the worm wheel which is not cost effective. The stress calculation of worm wheel at tooth thickness is a three dimensional problem. This paper represents the review of analysis of stress pattern by using 3D Photo elasticity techniques & FEA technique.

The Effect of Direct- and Cross-Rolling on Mechanical Properties and Microstr...Kaveh Rahimi Mamaghani
Severely deformed commercial pure aluminum sheets by constrained groove pressing are direct and crossrolled.
The grain size evolution and dislocation density during rolling are studied using Williamson-Hall
analysis on x-ray diffraction patterns of the deformed samples. These results and optical microscopy
observations show that subsequent direct or cross-rolling of constrained groove pressed aluminum can
produce elongated fine grains. The minimum crystallite size is achieved after cross-rolling of constrained
groove pressed samples. By direct-rolling or cross-rolling of annealed sheet, the maximum intensity in x-ray
diffraction patterns remains on (200) like annealed aluminum but direct-rolling or cross-rolling of constrained
groove pressed sheets changes the maximum intensity from (111) for constrained groove pressed
sheets to (220). Also, mechanical properties are studied using tensile test and hardness measurement. The
results show that cross-rolling on constrained groove pressed samples is more effective than direct-rolling in
mechanical properties improvement.
Cutting force and surface roughness in cryogenic machining of elastomerIAEME Publication
This document summarizes research on cryogenic machining of elastomers. Experiments were conducted to analyze the effects of rake angle, cutting speed, and feed rate on cutting force and surface roughness under ambient and cryogenic conditions. The results showed that cutting forces were higher for cryogenic machining but decreased with increasing rake angle. Cryogenic machining produced significantly lower surface roughness than ambient machining, especially at high rake angles and cutting speeds, due to increased material rigidity at lower temperatures.

IRJET- Modeling and Design Analysis of Die Profile of Extrusion of Square...IRJET Journal
This document discusses the modeling and design analysis of the die profile for extruding a square cross-section from a round billet using a non-linear converging die. Finite element method (FEM) simulations were conducted using DEFORM-3D software to analyze extrusion loads for different die profiles and process parameters. Experimental extrusion tests were also performed on lead and aluminum to validate the FEM results and investigate the effects of lubrication and splitting the workpiece. The non-linear cosine die profile was found to require less extrusion load than a linear die profile under the same conditions.
The document presents an experimental study on the effect of rivets on damping in jointed structures. Specifically, it investigates how the damping ratio of cantilever beams made of mild steel is affected by increasing the number of connecting rivets. Both experimental and finite element analysis are conducted. In the experiments, specimens of different thickness ratios and rivet configurations are tested using an FFT analyzer to determine their natural frequencies and damping ratios. The finite element models are developed in ANSYS and harmonic analysis is performed. The results show that the damping capacity increases substantially with more rivets, due to greater friction at the interfaces. Both experimental and FEA results are found to be in good agreement.

This study compared the manual widening of root canals with different degrees of curvature using Kerr file needles made of stainless steel or nickel-titanium alloy versus ProTaper cutters. The root canals were simulated with curvatures of 30, 45, 60, and 90 degrees and radii of 3, 4, and 5 mm based on 46 real patient cases. The results showed that Kerr files made of steel produced the greatest deviations from the natural root canal trajectory, while nickel-titanium alloy and ProTaper instruments produced less deviation. The highest modifications occurred with rigid instrumentation of extreme anatomies. Mathematically, nickel-titanium instruments, especially ProTaper, were shown to achieve more uniform widening of curved root
MODELING, ANALYZING AND SAFETY ASPECTS OF TORSION AND NOISE EFFECTS ON ROUND ...msejjournal
Each material has its own effect and behavior on external impacts like heat, force, tension, compression, torsion etc. It is important to study and analyze these behaviors before selecting a material for an engineering application in the design aspects itself. If predicted values analyzed by both mathematical and software are available it is easy to get the reliable details in the pre design itself. By this one can ensure the safety of the component and the system also. In this investigation, the effects of torsional loads on mild steel
round shafts with various diameters and lengths have been analyzed. The additional effects like angle of rotation, rpm and duration also considered to find the optimum predicted value. The data observed by various experiments are analyzed by design of experiments especially by response surface methodology. Minitab software is used for canalization. The data are tabulated and kept for future reference. Noise effect
due to the gradual torsional load performed in the gear box and other rotating components is also studied for healthy working environment. The nature and characteristics of material also be explained by this noise analysis.

Abstract The purpose of this study is to evaluation of the mechanical characterisation such as tensile, compression and bending test and to conduct wear test. This study focus on preparation and testing of Polyester resin using glass fibre for different orientation. The Mechanical properties of the polyester changes gradually by changing the layers of fibres and for different orientation of glass fibre the property differs. The laminate is prepared of size 300*300*4mm size and specimens are prepared as per ASTM standard, different layers of glass fibres are one, two and three layers and the orientation of glass fibre is 30o, 60o, and 90o. The glass fibre used is in fabric form. From the results which were obtained we can observed that three layers glass fibre for 90o orientation has improved tensile strength and the compressive strength is found to be more for 600orientation of glass fibre. And the wear rate is also less for three layer of glass fibre for 900 orientations. Keywords: Glass Fibre/Polyesters Composites, Mechanical Characterisation of Polyester, Orientation of Glass Fibre
Analysis of Parabolic Shell by Different Models Using Software SAP 2000ijtsrd
The shell structure consists of a thin reinforced concrete shell without the use of internal columns to create an internal opening., parabolic or spherical cross section. On the other hand, warehouses and playgrounds are conventional concrete frame structures, on the other hand, they can be difficult to design as the exact shape required for the stability of the structure depends on the material used, the dimensions of the enclosure, external or internal loads and other chamfers.. .. Thus, by changing the shell parameter, the performance of the shell will also change. The main goal of this work is to parametrically analyze different designs of cylindrical shells of different lengths in order to analyze two different lengths of taken cylindrical shells, and then change two parameters, first the radius and then the thickness, based on the radii. and the difference in thickness for the same width, length and material of the frame, we will evaluate the behavior of the frame for different models.

Analysis and Modeling of Steel Square Hollow Beam to Square Hollow Column Jointijtsrd
Most of the steel structures in India are made of conventional steel sections such as angle, channel and beam sections . However, new hollow steel sections such as square and rectangular hollow sections are gaining popularity in recent steel constructions due to a number of advantages such as its higher strength to weight ratio, better fire resistance properties, higher radius of gyration, lesser surface area, etc. This type of hollow sections can save cost up to 30 to 50 over the conventional steel sections. But unlike the conventional steel sections these hollow sections do not have standard connection details available in design code or in published literature. To overcome this problem the objective of the present study was identified to develop a suitable and economic connection detail between two square hollow sections which should be capable of transmitting forces smoothly and easy to be fabricated To achieve the above objective, a square hollow beam to square hollow column connection was selected and modeled in commercial finite element software ABAQUS. This model was analyzed for nonlinear static pushover analysis considering a number of connection details. Following four alternative scheme of connection details were selected for this study i using end plate, ii using angle section, iii using channel sections, and iv using collar plates. The base model rectangular hollow beam welded to one face of the rectangular hollow column is also studied for reference. The performance of the selected connection details are compared and the best performing connection details is recommended for rectangular hollow beam to rectangular hollow column joints. The result shows that the load carrying capacity of the joint and the maximum deformation capacity is highly sensitive to the type of connection used. Also, the location of formation of plastic hinges in the structure which can be at joint or at beam depends highly on the type of connection used.

Parametric Evaluation of Tall Structure with Various Lateral Load Resisting S...ijtsrd
The high rise buildings are majorly suffering with seismic forces, it can be found out by displacement parameter. The more the displacement the lesser will be the stiffness of the structure. The static analysis is having higher displacement value than response spectrum analysis. The increase in percentage is about 17 . This will increase the construction cost due to increase in stiffness. The base shear value increases with increase in weight of the structure. However, the diagrid structure seems to be having lesser weight than all other models. From the overall analysis it is proved that, diagrid structure is very much effective than any other structure. However, in case of constraint in providing diagrid due to its architectural features, the outrigger system with bracing will be very much effective.

This document summarizes research on the comparative behavior of different dome structures under various parameters. It begins by defining dome structures and their traditional materials of construction. It then discusses four main types of braced dome structures: ribbed domes, Schewedler domes, Kiewitt domes, and Kiewitt-ribbed domes. The document reviews several past studies that have analyzed the behavior and performance of these dome types under self-weight, seismic, and wind loads using structural analysis software. Most studies found that braced dome structures efficiently enclose large spaces with minimal material. The conclusions indicate braced domes are structurally stable and can be conveniently analyzed, with opportunities to optimize dome type based on span.

This study analyzed the behavior of rectangular box girder bridges with varying skew angles using finite element analysis in CSi Bridge software. The parameters analyzed included torsional moment, longitudinal moment, stresses, deflection, and required prestressing force. The results showed that as skew angle increased from 0 to 60 degrees, torsional moment increased by 1000% while required prestressing force and stresses at the bottom decreased. Longitudinal moment and maximum deflection also generally decreased with higher skew angles. The analysis provides useful insights into how changing skew angle impacts the structural behavior and design of box girder bridges.

This document presents a numerical study on the buckling behavior of corrugated hollow steel columns under axial loading using trapezoidal and sinusoidal corrugations. Finite element analysis was conducted in ANSYS to analyze rectangular hollow columns with and without ultra high strength steel tubes. Columns with trapezoidal corrugations and ultra high strength tubes exhibited the highest buckling load of 1269.04 kN, indicating greater load carrying capacity compared to other column designs. The study concluded that corrugated columns can carry double the load of conventional columns, are lighter and more efficient due to their hollow structure, and that ultra high strength tubular columns allow for even higher load capacities in a very thin cross-section.

Abstract The horizontally curved bridges are becoming the norm of highway interchanges and urban expressways as a result of complicated geometrics, limited rights of way, and traffic mitigation. This type of superstructure has gained popularity because it addresses the needs of transportation engineering. A study of box girder curved in plan with rectangular cross-section has been carried out in the present investigation. The finite element software ABAQUS is used to carryout analysis of these box girders. The analysis is carried out for the dead load, super imposed dead load and live load of IRC Class A loading. The paper presents a parametric study of curved box girders by varying span and radius of curvature and by keeping the span to depth ratio constant. The parametric investigations performed on curved box girders helps to evaluate the effects of different parameters on the behavior of the girder. This study would enable bridge engineers to better understand the behavior of curved concrete box girders. Key Words: Curved concrete box girder, ABAQUS

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

Disclosure is a process through which a business enterprise communicates with external parties. A corporate disclosure is communication of financial and non financial information of the activities of a business enterprise to the interested entities. Corporate disclosure is done through publishing annual reports. So corporate disclosure through annual reports plays a vital role in the life of all the companies and provides valuable information to investors. The basic objectives of corporate disclosure is to give a true and fair view of companies to the parties related either directly or indirectly like owner, government, creditors, shareholders etc. in the companies act, provisions have been made about mandatory and voluntary disclosure. The IT sector in India is rapidly growing, the trend to invest in the IT sector is rising and employment opportunities in IT sectors are also increasing. Therefore the IT sector is expected to have fair, full and adequate disclosure of all information. Unfair and incomplete disclosure may adversely affect the entire economy. A research study on disclosure practices of IT companies could play an important role in this regard.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy.

Graphs for the stresses
CONCLUSIONS:
The observations of the study are as follows:
The effect of rise: By increasing the rise stresses are
minimum for 2.25m rise, for shallowanddeepshell theloads
are resisted by stresses as compare to intermediate rise.
Shells with intermediate rise moment plays major role.
Transverse normal shear is played negligible part in loads
resistance.
The effect of thickness: longitudinal stressesplaysmajorrole
in resisting the loads compare to other two stresses, the
transverse normal stress is negligible with thickness.
Moments are increasing with thickness.Transversemoment
increases more in comparison of longitudinal moments.
The effect of skew angle: The longitudinal stress decrease as
the skew angle increase ,transverse stress increase as the
skew angle increases .The in plane shear stress almost
remain constraint there for it can be concluded that the role
of resistance to load shift from longitudinal stress to
transverse as skew angle increases.
Longitudinal Moment does not varies much the transverse
moment increases for skew angle in 30, 45 but more
increases in 30.Further the transverse moment has more
than double in all cases which shows transverse moment
plays the major role in resisting the load.
