Exhibition center, the place for holding exhibitions and conventions, is one of the most important elements for the development of exhibition industry. A modernized exhibition center constitutes one part of exhibition brand. The extent of exhibition center modernization will effect the success of exhibitions held there directly. This article will analyze the meaning of exhibition center modernization...
With the extensive application of pre-twisted beam in engineer structure, it is very important to carry out systematic analytical research of pre-twisted beam, put forward a dependable mechanics analysis model and the calculation theories. The paper carries on mechanical property based on small deformation assumption to get the displacement general solution, and verify its accuracy using ANSYS software...
In order to understand the fluid distribution, the square ECM machining gap flow field mathematical model has been built. It is based on the current flow field theory of ECM; and the machining gap of ECM the square hole is taken as the research subject. COMSOL software and computational fluid dynamics (CFD) have been applied. Under the condition of the same inlet flow velocity and outlet pressure,...
Molecular shape is one of the most critical factors that determine molecular function. To properly understand the function of a molecule, it is necessary to explore its geometric properties more effectively and efficiently in addition to its physicochemical properties. Due to the complexity of the problems in biomolecular structure, in-silico approach is inevitable for many cases and is becoming more...
Currently, with many popular GIS software platforms occurring, interoperating data in different platforms has an important application value. Taking MIF data for an example, which is the Interchange Format of MapInfo, this article puts forward three ways of MIF data interoperability in ArcGIS platform through the analysis of data format of MIF, namely interoperated Quick Import tool for calling data,...
Regression testing is a very important part of the program development cycle as it should be executed after feature is integrated or bugs are fixed each time. There are hundreds of test cases in the case library for a little complex product, it is impossible to perform all of the test cases in regression testing every time. Test engineers always select the regression cases by their experience only,...
The paper tried to build the classification model of cashew nuts and had analyzed the shape parameters of cashew nuts, and the paper concluded that there was a clear linear relationship between the length and height of cashew nuts and there was not a clear linear relationship between the length and thickness of cashew nuts or between the height and thickness of cashew nuts. Because of the restrictions...
This paper describes an optimized embedded memory diagnosis flow that exploits many levels of knowledge to produce accurate failure hypothesis. The proposed post-processing analysis flow is composed of many steps investigating failure shapes as well as cell fail syndromes, and includes advanced techniques to tackle incomplete data possibly due to tester noise and/or by faults showing intermittent...
Effective designs rarely emerge from good structural design or aesthetics alone. It is more often the result of the end product's overall design integrity. Added to this, design is inherently an interdisciplinary collaborative activity. With this in mind, today's tools are not powerful enough to design complex physical environments, such as command control centers or hospital operating theaters. In...
Percutaneous heart valve replacement is an exciting and innovative technology which provides new treatment options for previously untreatable patients. Despite promising clinical results for the currently available prostheses by Edwards Lifesciences and Medtronic, these devices still require improvement in order to represent a true alternative to conventional heart valve replacement surgery. One of...
A novel approach of sheet electron beam transport under uniform magnetic field through a tunnel of particular shape and size is described here. The space charge field for rectangular beam trough rectangular tunnel, elliptical beam through rectangular tunnel, elliptical beam through elliptical tunnel is analyzed numerically. This analysis shows that component of space charge field along direction of...
Testing cold extrusion forming process of the hexagonal bowl auto part by DEFORM-3D on the paper. By comparing the feasibility obtained through numerical simulation testing and analysis of the two forming plans, according to the final test results to determine a reasonable extrusion program. At the same time, actual production the cold extrusion plan is feasible.
Genetic Algorithm (GA) methodology was used to design a Phased Array Radar producing three different constrained beam shapes; COSEC2 pattern for 30 degree of elevation angle, narrow pencil beam with 2 degree beamwidth and SLL of −40 dB, and a three simultaneously pencil beams. Related software's code is introduced based on GA approach with some unique improvements in GA to find appropriate feedings...
The disdrometer data on rain drop sizes, collected at Ahmedabad (India), has been analyzed to develop empirical model on drop-size distribution (DSD). Analyses has been carried out to find suitability of lognormal or gamma distribution. The lognormal distribution has been found to give better correlation. The data has been analysed on annual and monthly basis to find out seasonal variability. Statistical...
This particular essay expounds upon how one can foresee and predict software reliability. There are two major components that exist within a computer system: hardware and software. The reliabilities between the two are comparable because both are stochastic processes, which can be described by probability distributions. With this said, software reliability is the probability that will function without...
A new method, using fractal dimension of silt floc pores to study the settling performance of silt floc, was put forward. Firstly, the fractal characteristics of silt floc pores were descried qualitatively by the software of image-pro plus6.0, which was taken from Shahu Lake in Wuhan city. Secondly, two-dimensional fractal dimension of silt floc pores was calculated by image analysis. At last, the...
By considering the customer as a partner in value creation, co-design, as a customer-supplier collaborative design endeavor, is becoming more common to integrate users into design and production processes as a promising strategy for companies to react to the growing individualization of demand. The computer mouse, a critical human-machine interface device, still has very little choice in terms of...
Digitally adjustable tooling using multi-point forming methodology is a flexible manufacturing technology for aircraft panels. It includes multi-point press forming and multi-point stretch forming which are used in the forming of three dimensional aluminum alloy panels and multi-point positioning tool which is used in subsequent assembly operation. The deformation mechanism of the multi-point die...
One of oldest and best-known methods used in constructive testing of smaller programs is the symbolic program execution. It is partly similar to method of simulation of computer function, but differs in aim. One of ways to prove whether given program is written correctly is to execute it symbolically. Aim of this paper is to test ramified program structure using single symbolic set of inputs, in one...
