Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

An In-Depth Exploration of Natural Language Processing: Evolution, Applicatio...DharmaBanothu
Natural language processing (NLP) has
recently garnered significant interest for the
computational representation and analysis of human
language. Its applications span multiple domains such
as machine translation, email spam detection,
information extraction, summarization, healthcare,
and question answering. This paper first delineates
four phases by examining various levels of NLP and
components of Natural Language Generation,
followed by a review of the history and progression of
NLP. Subsequently, we delve into the current state of
the art by presenting diverse NLP applications,
contemporary trends, and challenges. Finally, we
discuss some available datasets, models, and
evaluation metrics in NLP.

Consolidation Settlement Calculation Program-The Python Code
By Professor Dr. Costas Sachpazis, Civil Engineer & Geologist
This program calculates the consolidation settlement for a foundation based on soil layer properties and foundation data. It allows users to input multiple soil layers and foundation characteristics to determine the total settlement.
2. An estimate is an anticipated or probable cost of a work
and is usually prepared before the construction is taken
up.
Before undertaking any work or project it is necessary
to know the probable cost which is obtained by
estimating.
The estimate is prepared by computing the quantities
required and then calculating the cost at suitable rates,
to get the expenditure likely to be incurred in the
construction of the work or structure. Prepared by:-
P.GAYATHRI
A.P, Civil Engg.
AEC
3. Drawings( Plans, section, etc)
Specifications
a) General Specifications: This gives the nature,
quality, class of work and materials in general terms to be used
in various parts of work. It helps to from a general idea of
building.
b) Detailed Specifications: These gives the detailed
description of the various items of work laying down the
Quantities and qualities of materials, their proportions, the
method of preparation workmanship and execution of work.
4. Rates :
For preparing the estimate the unit rates of each
item of work are required.
For arriving at the unit rates of each item.
The rates of various materials to be used in the
construction.
The cost of transport materials.
The wages of labor, skilled or unskilled of masons,
carpenters, Mazdoor etc
6. Preliminary/Appx./Abstract/Rough Cost Estimate
Plinth Area Estimate
Cube Rate or Cubical Content Estimate
Appx. Quantity Method Estimate
Detailed Estimate or Item Rate Estimate
Revised Estimate
Supplementary Estimate
Supplementary and Revised Estimate
Annual Repair or Maintenance Estimate (A.R or A.M
Estimate)
7. Preliminary Estimate is prepared by various ways for different
structures as mentioned below :
Buildings
Per Unit Basis – Per student for schools and hostels, per class room
for schools, per bed for hospitals, per seat for cinema and theatre
halls, per tenement for residential buildings.
Plinth area basis
Cubic content basis
Appx. Quantity method
Roads and Highways – Per km basis depending upon nature of
road, width and thickness of metalling.
Irrigation Channels
Per km basis
Per hectare basis (Area of land commanded)
8. Bridges and Culverts – Per running meter of span depending
upon type of structure, type and depth of foundation.
Sewerage and Water Supply Project
Per head of population served
Per hectare basis (Area covered)
Over Head water Tank – Per liter or per gallon of tank
depending upon type of structure and height of tank.
9. Plinth area is approximate estimate
Plinth area should be calculated for covered area by taking
external dimensions of the building at the floor level
Courtyard and other open area should not be included
For multi storeyed building Plinth Area for each storey is
determined separately.
Plinth area rate is known from cost of similar building in the
locality.
Estimate is prepared by
Plinth area × Plinth area rate
10. Cube rate estimate is again approximate estimate
Cubical content of the building is determined by multiplying
length, breadth and height of the building.
External length and breadth at the floor level are calculated
for the purpose
Height should be taken from the floor level to the top of roof.
For multi storeyed building height is taken from floor level of
one storey to top of next higher floor.
Cube rate estimate is more accurate as compared to the
plinth area estimate.
Cubical content= plinth area × height
11. Structure divided into two parts – (i) Foundation including
plinth (ii) Superstructure
Total length of walls is found out.
Tofind running meter rate of foundation, appx. quantities of
various items are calculated per running meter
Similarly for superstructure appx. Quantities of brickwork,
roof, flooring etc is calculated per running meter.
12. It is the accurate estimate prepared by working out quantities of
each items of work.
It is prepared in two stages –
Details of measurements and calculation of quantities.
Abstract of estimated cost – 3% to 5% of estimated cost is added to
cover miscellaneous expenditure
Detailed estimate is prepared work-wise.
Detailed estimate consists of –
Report
General Specifications
Detailed specifications
Drawings
Calculation and designs
Analysis of rates
Detailed estimate is prepared for technical sanction, for
arranging contract and for execution of project.
13. Revised estimate is prepared when original sanctioned
estimate is likely to exceed more than 5%.
When expenditure on work is likely to exceed
amount of administrative sanction by more than
10%
When there are material deviation from original proposal
even though cost may be met from sanctioned cost.
It is accompanied by comparative statement showing
variations in each item of works and reason for the same.
14. It is the fresh detailed estimate of the additional works in
addition to the original estimate.
It is required when further development is required during the
progress of work.
Abstract should show the amount of original estimate and
total amount including supplementary amount.
15. When a work is partially abandoned and estimated cost of remaining
work is less than 95% of original sanctioned estimate.
When there are material deviations and changes in the design
If at any time before or during the execution of work, it is found that
original estimate is excessive then divisional officer may sanction a
revised estimate of reduced amount.
16. It is prepared to maintain structure or work in proper order
and safe condition
For buildings like white washing, painting, minor repairs etc.
For road works A.R. estimate provides for patch repairing,
repairs of bridges and culverts etc.
17. Long wall - short wall method
Centre line method.
Partly centre line and short wall method
18. In this method, the wall along the length of room is
considered to be long wall while the wall perpendicular to
long wall is said to be short wall.
To get the length of long wall or short wall, calculate first
the centre line lengths of individual walls.
Then the length of long wall, (out to out) may be calculated
after adding half breadth at each end to its centre line
length. Thus the length of short wall measured into in and
may be found by deducting half breadth from its centre line
length at each end. The length of long wall usually
decreases from earth work to brick work in super structure
while the short wall increases. These lengths are multiplied
by breadth and depth to get quantities.
20. Long wall length (out to out)= centre to
centre length + half breadth on one side+
half a breadth on other side
(Or)=centre to centre length + one breadth
Short wall length=centre to centre length –
one breadth
21. This method is suitable for walls of similar cross
sections.
Here the total centre line length is multiplied by
breadth and depth of respective item to get the
total quantity at a time.
When cross walls or partitions or verandah walls
join with main all, the centre line length gets
reduced by half of breadth for each junction.
such junction or joints are studied carefully while
calculating total centre line length.
The estimates prepared by this method are most
accurate and quick.
23. This method is adopted when external (i.e.,
alround the building) wall is of one thickness
and the internal walls having different
thicknesses.
In such cases, centre line method is applied
to external walls and long wall short wall
method is used to internal walls.
This method suits for different thicknesses
walls and different level of foundations.
Because of this reason, all Engineering
departments are practicing this method.
24. Contingencies – Indicates incidental expenses of
miscellaneous character which cannot be classified under any
distinct item. (3% to 5% of the estimated cost is provided to allow
for contingencies)
Work-charged Establishment – Work-charged employees are
temporary staff whose services are terminated at the expiry of
sanctioned period but usually one month notice is given. (1 .5% to
2% of the estimated cost is added)
Tools and Plants – Normally contractor has to arrange tools and
plants. (1% to 1 .5% of estimated cost is provided)
Centage charges or Departmental charges – Also known as
Supervision charges for works. Tomeet the expenses of
establishment, designing, planning, supervision etc. (10% to 15% of
the estimated cost). When engineering department takes up work of
other department.
25. Expenditure Sanction – It represents allotment of money to
meet the expenditure. It is usually accorded by Finance
Department.
Technical Sanction – It is the sanction of the detailed
estimate, design calculation, quantities of work etc. Technical
sanction is accorded by engineering department and
execution of work is carried out thereafter.
Quantity Survey – It means estimating of quantities of
different items of works.
26. Sub-Head items of work – Works like earthwork, concrete
work, brick work etc. Under each sub head there are different items
of work.
Sub- Work – Large project may consist of several buildings.
Detailed estimate of each sub-work is prepared separately.
Schedule of Rates – It is a list of rate of various items of
works maintained by engineering department under the name
“Schedule of Rates Book”. “Road Metal Rate Book” is also
maintained by PWD.
Administrative Sanction/ Approval – It is the formal
acceptance by the department concerned of the proposal. After
the approval, design, estimates etc. are prepared and thereafter
execution of work.
