Novel UML and Interaction Design Based Paradigm of Multimedia Software Design

With Internet technology research and gradually used in modern distance education practice, high-bandwidth, high-speed, high-reliability remote education network will be able to provide better education services to create some more opportunities and possibilities. Multimedia courseware contains audio, video and other large-capacity information object, it has been widely used in practice of distance education, distance education and the overall quality of service has a greatly improved. However, due to the current courseware file size is very large, the user wants to browse the courseware, need to start on the site to download and then watch to play, if the change in the place of learning, we need to download again, very cumbersome and inefficient. In order to facilitate the user can at any time and place can conveniently browse online courseware streaming media technology came into being. Streaming media technology has been widely used in audio, video online play. Times for large data interaction design connotation and denotation, and development course contents and scope, we analyze and estimate the large interaction design trends in the information age of big data interaction design methods, processes, architectures, models and assessments, to explore a large design interactive design strategy and design details.

An Approach of Trustworthy Software Design with Automatically Adapting Software Update

In this paper, we merge software trustworthiness with software design and present an approach to trustworthy software design with an automatically adapting software update. First, software behavior and results can be expected and behavior states can be monitored when a software runs by introducing a trustworthy behavior trace on a software and inserting a checkpoint sensor at each checkpoint of the trustworthy software. Second, an updated approach of the trustworthy behavior trace for the software at the level of checkpoints is presented. The trustworthy behavior traces of the software for two versions can be merged adequately by constructing split points and merge points between two trustworthy behavior traces. Finally, experiments and analyses show that： （1） the software designed by our approach can detect and report the anomaly in a software automatically and effectively, so it has a higher ability of trustworthiness evaluation than the traditional software; and （2） our approach can realize the accurate update of the trustworthy behavior trace with a lower space overhead of checkpoints when the software updates.

Design of Finite Element Tools for Coupled Surface and Volume Meshes

Many problems with underlying variational structure involve a coupling of volume with surface effects.A straight-forward approach in a finite element discretiza- tion is to make use of the surface triangulation that is naturally induced by the volume triangulation.In an adaptive method one wants to facilitate'matching'local mesh modifications,i.e.,local refinement and/or coarsening,of volume and surface mesh with standard tools such that the surface grid is always induced by the volume grid. We describe the concepts behind this approach for bisectional refinement and describe new tools incorporated in the finite element toolbox ALBERTA.We also present several important applications of the mesh coupling.

Control of Surface Thermal Scratch of Strip in Tandem Cold Rolling

The thermal scratch seriously affects the surface quality of the cold rolled stainless steel strip. Some researchers have carried out qualitative and theoretical studies in this field. However, there is currently a lack of research on effective forecast and control of thermal scratch defects in practical production, especially in tandem cold rolling. In order to establish precise mathematical model of oil film thickness in deformation zone, the lubrication in cold rolling process of SUS410L stainless steel strip is studied, and major factors affecting oil film thickness are also analyzed. According to the principle of statistics, mathematical model of critical oil film thickness in deformation zone for thermal scratch is built, with fitting and regression analytical method, and then based on temperature comparison method, the criterion for deciding thermal scratch defects is put forward. Storing and calling data through SQL Server 2010, a software on thermal scratch defects control is developed through Microsoft Visual Studio 2008 by MFC technique for stainless steel in tandem cold rolling, and then it is put into practical production. Statistics indicate that the hit rate of thermal scratch is as high as 92.38%, and the occurrence rate of thermal scratch is decreased by 89.13%. Owing to the application of the software, the rolling speed is increased by approximately 9.3%. The software developed provides an effective solution to the problem of thermal scratch defects in tandem cold rolling, and helps to promote products surface quality of stainless steel strips in practical production.

Blockchain software patterns for the design of decentralized applications:A systematic literature review

A software pattern is a reusable solution to address a commonly occurring problem within a given context when designing software.Using patterns is a common practice for software architects to ensure software quality.Many pattern collections have been proposed for a large number of application domains.However,because of the technology's recentness,there are only a few available collections with a lack of extensive testing in industrial blockchain applications.It is also difficult for software architects to adequately apply blockchain patterns in their applications,as it requires deep knowledge of blockchain technology.Through a systematic literature review,this paper has identified 120 unique blockchain-related patterns and proposes a pattern taxonomy composed of multiple categories,built from the extracted pattern collection.The purpose of this collection is to map,classify,and describe all the available patterns across the literature to help readers make adequate decisions regarding blockchain pattern selection.This study also shows potential applications of those patterns and identifies the relationships between blockchain patterns and other non-blockchain software patterns.

On Exploring Method and Software for Evaluating Effectiveness of Military Training Aircraft

The evaluation of training effectiveness （TE） of military training aircraft, though obviously very important, appears to have attracted much less attention than what it deserves in the open literature. This article aims to start from previous studies and explore further. First, TE of military training aircraft is discussed and our ideas for evaluating TE which are expressed mathematically are proposed. Then, using the presented mathematical models, software is developed that takes into consideration the influence of parameters of flight performance and quality on TE. The software＇s environment is Borland C＋＋ and it sets up the parameters of trainer, training standard databases and training documents; it can analyze and then give the operational cost and cost-effectiveness ratio of military trainer. Finally, the software is utilized to compare the TEs of HAWK and MB339 with that of Chinese Air Force TF-6. The results of comparison show that the TE of TF-6 is the lowest.

Software defect prevention based on human error theories

Software defect prevention is an important way to reduce the defect introduction rate.As the primary cause of software defects,human error can be the key to understanding and preventing software defects.This paper proposes a defect prevention approach based on human error mechanisms：DPe HE.The approach includes both knowledge and regulation training in human error prevention.Knowledge training provides programmers with explicit knowledge on why programmers commit errors,what kinds of errors tend to be committed under different circumstances,and how these errors can be prevented.Regulation training further helps programmers to promote the awareness and ability to prevent human errors through practice.The practice is facilitated by a problem solving checklist and a root cause identification checklist.This paper provides a systematic framework that integrates knowledge across disciplines,e.g.,cognitive science,software psychology and software engineering to defend against human errors in software development.Furthermore,we applied this approach in an international company at CMM Level 5 and a software development institution at CMM Level 1 in the Chinese Aviation Industry.The application cases show that the approach is feasible and effective in promoting developers＇ ability to prevent software defects,independent of process maturity levels.
