Abstract: The initial dimensions and weight for the vehicle is considered from the Audi A8 vehicle as a reference. The specifications for the motor and battery are considered for the Mahindra e2o electric vehicle of similar dimensions. The main objective of this paper is to model and perform static analysis on the chassis of a four-seater car. The initial design for the chassis was a space frame body which is very rigid and had very less deflection. The second and final chassis is a ladder type chassis which is most common chassis type being used in Nepal and India. The difference in deflection between both the chassis type is very less, which is about 0.3235 mm for a reasonable reduction in weight which is about 120 Kg. The simulation part is carried out in ANSYS software. The result is selection of best suitable material for chassis on the basis of ANSYS and theoretically calculated result. Keywords: Chassis, Structural Analysis, Optimization, Four seater car

Noroviruses (NoVs) and rotaviruses (RVs), the two most important causes of viral acute gastroenteritis, are found to recognise histo-blood group antigens (HBGAs) as receptors or ligands for attachment. Human HBGAs are highly polymorphic containing ABO, secretor and Lewis antigens. In addition, both NoVs and RVs are highly diverse in how they recognise these HBGAs. Structural analysis of the HBGA-binding interfaces of NoVs revealed a conserved central binding pocket (CBP) interacting with a common major binding saccharide (MaBS) of HBGAs and a variable surrounding region interacting with additional minor binding saccharides. The conserved CBP indicates a strong selection of NoVs by the host HBGAs, whereas the variable surrounding region explains the diverse recognition patterns of different HBGAs by NoVs and RVs as functional adaptations of the viruses to human HBGAs. Diverse recognition of HBGAs has also been found in bacterial pathogenHelicobacter pylori. Thus, exploratory research into whether such diverse recognitions also occur for other viral and bacterial pathogens that recognise HBGAs is warranted.

Summary This paper lists all the known published work on the development of automatic selection of redundancy techniques over the past decade. The main interest is a selection technique based on an algebraic procedure. It is emphasised that such a technique is very flexible in its application and that the redundancy selection can be completely automatic, completely preselected but automatically imposed or a combination of the two. This enables previous experience to be applied. The criterion is given for optimum redundancy selection and items which influence this are discussed. It is pointed out that the basic and redundant load transformation matrices can be generated automatically for general configurations.

This chapter examines how the entire text of the Babylonian law code was reworked under each king who commissioned them. The overall character of the law codes and the manner of formulation remained the same, but the authors felt free to change the order and selection of paragraphs. At the core of all the codes is a list. What we call paragraphs are statements phrased in a limited number of formats and strung together just like the entries of the lexical and omen lists. The chapter offers a structural analysis of the codes that looks at each entry as a syntagm and at the sequence of entries as a paradigm. It shows that the royal proclamations of laws guaranteed that there was a coherent system of justice in place, and even more, that it was grounded in wisdom.

The article gives a detailed commentary on the theory of technological structures developed in line with the modern Russian economic school (first of all — by academician S. Yu. Glaziev and his associates), and an attempt is made to develop it in a number of methodological, theoretical-content and methodical aspects. In this target context, the authors, starting from the existing taxonomy of technological orders, firstly, touch upon not only the issue of identifying (measuring) structures, but also the problem of assessing the contribution of the latter to economic growth. Secondly, they propose an approach to solving the problem of assessing the influence of macroeconomic policy instruments on each of the structures identified by science, which has not yet been solved by domestic and foreign scientists. This means instrumentalizing the theory of technological structures and expanding the scope of its application. We are talking about the use of the considered theory not only in the structural analysis of economic growth and technological changes in the national economy, but also in the development of a strategy for the development of the national economy, in the selection of economic policy instruments. At the same time, it is proposed to put such selection on a solid basis for the application of precise methods. Several dozen regressions have been analyzed for the basic tools of macro-policy — with the rejection of factors and the choice of equations for the best statistics.


Two systematic methods of selecting redundant forces and moments are presented which are suitable for computer programs based on the ‘force’ method of structural analysis. To illustrate the application of the methods a computer program is described which calculates the rigid-plastic collapse load of a two-dimensional structural frame from a specification of its geometry and loading. The program also computes the mode of collapse and produces a drawing of the deformed structure on an automatic plotter.

The mechanics of masonry structures have been underdeveloped for a long time in comparison with other fields of knowledge. Presently, nonlinear analysis is a popular field in masonry research and homogenization techniques play a major role despite the mathematical and conceptual difficulties inherent to this approach. This paper addresses different homogenization techniques available in published literature, aiming at defining a first catalogue and at discussing the advantages and disadvantages of the different approaches. Finally, special attention is given to a micromechanical based model and a model based on a polynomial expansion of the microstress field. These seem promising and accurate strategies for advanced structural analysis.

This study seeks to identify interproduct relationships between domestic catfish and a representative selection of imported seafood. In doing so, this study uses multivariate cointegration and structural analyses. Multivariate cointegration analysis suggests that six imported seafood product groupings form a common market with domestic catfish. Structural analysis reveals that 1) domestic and imported catfish are net and gross quantity substitutes; 2) domestic catfish and imported seafood are normal goods; 3) six imported seafood products are identified as gross quantity substitutes for domestic catfish; and 4) according to the derived Allais coefficients, interaction intensities of imported seafood for domestic catfish (from greatest to least) are as follows: tuna, shrimp, salmon, tilapia, catfish, and trout.
