In this paper, transverse vibrations of thin circular plates with guided edge and resting on Winkler foundation have been studied on the basis of Classical Plate Theory. Parametric investigations on the vibration of circular plates resting on elastic foundation have been carried out with respect to various foundation stiffness parameters. Twelve vibration modes are presented. The location of th...

First, we prove the function g is an injection (i.e., g is one-to-one). We need to prove that if g(m) = g(n) --(1), where m and n are two integers, then m = n --(2). Since g(m) (and also g(n)) can be defined by two different formulas depending whether the argument m (and n) is even or odd, we consider the following 3 cases: (Case 1) Both m and n are even. In this case, (1) implies 1 – m = 1 – n...

as claimed by many behavioral scientists, designing should be based on the knowledge of interaction between human and environment. environmental quality is also created in the context in which humans interact with their environment. to achieve such quality, designers should develop appropriate models for explaining this relationship, and this requires an understanding of human nature and the en...

study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. the process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. by means, abaqus software was applied for the finite elem...

The introduction of Eurocode in Kazakhstan allows for the application modern technological innovations and elimination technical barriers realization international projects. It is significant to study standards design requirements provided Eurocode. This presents a comparative analysis Kazakhstani European approaches geotechnical foundations provides methods considered codes practice. Three dif...

background: data mining (dm) is an approach used in extracting valuable information from environmental processes. this research depicts a dm approach used in extracting some information from influent and effluent wastewater characteristic data of a waste stabilization pond (wsp) in birjand, a city in eastern iran. methods: multiple regression (mr) and neural network (nn) models were examined us...

The random coefficients multinomial choice logit model, also known as the mixed logit, has been widely used in empirical choice analysis for the last thirty years. We prove that the distribution of random coefficients in the multinomial logit model is nonparametrically identified. Our approach requires variation in product characteristics only locally and does not rely on the special regressors...
