Tension members can fail due to three modes:
1. Gross section yielding, where the entire cross-section yields
2. Net section yielding, where the reduced cross-section after subtracting holes yields
3. Block shear failure, which also occurs in welded connections along planes of shear and tension
The design strength is the minimum of the strengths from these three failure modes. Block shear is demonstrated using a failed gusset plate connection with failure planes around the weld. The problem determines the tensile strength of a plate connected to a gusset plate, calculating the strength based on gross section yielding, net section yielding, and block shear failure.

DESTRUCTIVE AND NON-DESTRUCTIVE TEST OF CONCRETEKaran Patel
The standard method of evaluating the quality of concrete in buildings or structures is to test specimens cast simultaneously for compressive, flexural and tensile strengths.
The main disadvantages are that results are not obtained immediately; that concrete in specimens may differ from that in the actual structure as a result of different curing and compaction conditions; and that strength properties of a concrete specimen depend on its size and shape.
Although there can be no direct measurement of the strength properties of structural concrete for the simple reason that strength determination involves destructive stresses, several non- destructive methods of assessment have been developed.
The document discusses effective stress in soils. It defines total stress, pore water pressure, and effective stress. Total stress is the load carried by the soil grains and water. Pore water pressure depends on depth and water flow conditions. Effective stress is the difference between total stress and pore water pressure, and represents the stress carried by the soil skeleton. Effective stress applies to saturated soils and influences properties like compressibility and consolidation. It is an imaginary parameter that cannot be directly measured but is important in soil mechanics analyses.

The base course provides a flexible pavement base for short roads or small projects where a hot mix plant is not available.

The document discusses factors that affect the strength of concrete, including water-cement ratio, aggregate-cement ratio, maximum aggregate size, and degree of compaction. It states that concrete strength is inversely proportional to water-cement ratio according to Abrams' law. A lower water-cement ratio and higher degree of compaction produce stronger concrete by reducing porosity. A leaner aggregate-cement ratio also increases strength by absorbing water and reducing shrinkage. Larger aggregate size can reduce water needs but may decrease strength by lowering surface area for bond development.

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.

Cricket management system ptoject report.pdfKamal Acharya
The aim of this project is to provide the complete information of the National and
International statistics. The information is available country wise and player wise. By
entering the data of eachmatch, we can get all type of reports instantly, which will be
useful to call back history of each player. Also the team performance in each match can
be obtained. We can get a report on number of matches, wins and lost.
Covid Management System Project Report.pdfKamal Acharya
CoVID-19 sprang up in Wuhan China in November 2019 and was declared a pandemic by the in January 2020 World Health Organization (WHO). Like the Spanish flu of 1918 that claimed millions of lives, the COVID-19 has caused the demise of thousands with China, Italy, Spain, USA and India having the highest statistics on infection and mortality rates. Regardless of existing sophisticated technologies and medical science, the spread has continued to surge high. With this COVID-19 Management System, organizations can respond virtually to the COVID-19 pandemic and protect, educate and care for citizens in the community in a quick and effective manner. This comprehensive solution not only helps in containing the virus but also proactively empowers both citizens and care providers to minimize the spread of the virus through targeted strategies and education.

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.
