Quality assessment technique for ubiquitous software and middleware

The new paradigm of computing or information systems is ubiquitous computing systems. The technology-oriented issues of ubiquitous computing systems have made researchers pay much attention to the feasibility study of the technologies rather than building quality assurance indices or guidelines. In this context, measuring quality is the key to developing high-quality ubiquitous computing products. For this reason, various quality models have been defined, adopted and enhanced over the years, for example, the need for one recognised standard quality model (ISO/IEC 9126) is the result of a consensus for a software quality model on three levels: characteristics, sub-characteristics, and metrics. However, it is very much unlikely that this scheme will be directly applicable to ubiquitous computing environments which are considerably different to conventional software, trailing a big concern which is being given to reformulate existing methods, and especially to elaborate new assessment techniques for ubiquitous computing environments. This paper selects appropriate quality characteristics for the ubiquitous computing environment, which can be used as the quality target for both ubiquitous computing product evaluation processes ad development processes. Further, each of the quality characteristics has been expanded with evaluation questions and metrics, in some cases with measures. In addition, this quality model has been applied to the industrial setting of the ubiquitous computing environment. These have revealed that while the approach was sound, there are some parts to be more developed in the future

Distributed Application as a new application Standard

The constant growth in IT field more precisely the Internet, determines the need of new technologies and applications which can provide new possibilities and accessibility to the contemporaneous information society. The field of construction, isn’t a domain that has not information systems but there is still one way to distribute information for this domain that isn’t enough developed. The way to distribute processed information for this domain can be the Internet. This paper describes the way to develop an application that easy the process of centralization, distribution, and analysis of information gathered from the construction site to the headquarters and then to the final users who signed the contract with the construction company to build the construction. The IT solution implies the use of new technologies for communicating and centralizing the information, that simplifies the way information travels between departments and finally to the end-user, with the benefit of the Internet and VPN.distributed applications, vpn, domains

DIVERSE: a Software Toolkit to Integrate Distributed Simulations with Heterogeneous Virtual Environments

We present DIVERSE (Device Independent Virtual Environments- Reconfigurable, Scalable, Extensible), which is a modular collection of complimentary software packages that we have developed to facilitate the creation of distributed operator-in-the-loop simulations. In DIVERSE we introduce a novel implementation of remote shared memory (distributed shared memory) that uses Internet Protocol (IP) networks. We also introduce a new method that automatically extends hardware drivers (not in the operating system kernel driver sense) into inter-process and Internet hardware services. Using DIVERSE, a program can display in a CAVE™, ImmersaDesk™, head mounted display (HMD), desktop or laptop without modification. We have developed a method of configuring user programs at run-time by loading dynamic shared objects (DSOs), in contrast to the more common practice of creating interpreted configuration languages. We find that by loading DSOs the development time, complexity and size of DIVERSE and DIVERSE user applications is significantly reduced. Configurations to support different I/O devices, device emulators, visual displays, and any component of a user application including interaction techniques, can be changed at run-time by loading different sets of DIVERSE DSOs. In addition, interpreted run-time configuration parsers have been implemented using DIVERSE DSOs; new ones can be created as needed. DIVERSE is free software, licensed under the terms of the GNU General Public License (GPL) and the GNU Lesser General Public License (LGPL) licenses. We describe the DIVERSE architecture and demonstrate how DIVERSE was used in the development of a specific application, an operator-in-the-loop Navy ship-board crane simulator, which runs unmodified on a desktop computer and/or in a CAVE with motion base motion queuing

Application for managing container-based software development environments

Abstract. Virtualizing the software development process can enhance efficiency through unified, remotely managed environments. Docker containers, a popular technology in software development, are widely used for application testing and deployment. This thesis examines the use of containers as cloud-based development environments. This study explores the history and implementation of container-based virtualization before presenting containers as a novel cloud-based software development environment. Virtual containers, like virtual machines, have been extensively used in software development for code testing but not as development environments. Containers are also prevalent in the final stages of software production, specifically in the distribution and deployment of completed applications. In the practical part of the thesis, an application is implemented to improve the usability of a container-based development environment, addressing challenges in adopting new work environments. The work was conducted for a private company, and multiple experts provided input. The management application enhanced the container-based development environment’s efficiency by improving user rights management, virtual container management, and user interface. Additionally, the new management tools reduced training time for new employees by 50%, facilitating their integration into the organization. Container-based development environments with efficient management tools provide a secure, efficient, and unified platform for large-scale software development. Virtual containers also hold potential for future improvements in energy-saving strategies and organizational work method harmonization and integration.Sovellus konttipohjaisten ohjelmistonkehitysympäristöjen hallintaan. Tiivistelmä. Ohjelmistokehitysprosessin virtualisointi voi parantaa tehokkuutta yhtenäisten, etähallittujen ympäristöjen avulla. Ohjelmistonkehityksessä suosittu ohjelmistonkehitysteknologia, Docker-kontteja käytetään laajalti sovellusten testaamisessa ja käyttöönotossa. Tässä opinnäytetyössä tarkastellaan konttien käyttöä pilvipohjaisina kehitysympäristöinä. Tämä tutkimus tutkii konttipohjaisen virtualisoinnin historiaa ja toteutusta, jonka jälkeen esitellään konttien käyttöä uudenlaisena pilvipohjaisena ohjelmistokehitysympäristönä. Virtuaalisia kontteja, kuten virtuaalikoneita, on käytetty laajasti ohjelmistokehityksessä kooditestauksessa, mutta ei kehitysympäristöinä. Kontit ovat myös yleisiä ohjelmistotuotannon loppuvaiheissa, erityisesti valmiiden sovellusten jakelussa ja käyttöönotossa. Opinnäytetyön käytännön osassa toteutetaan konttipohjaisen kehitysympäristön käytettävyyttä parantava sovellus, joka vastaa uusien työympäristöjen käyttöönoton haasteisiin. Työ suoritettiin yksityiselle yritykselle, ja sen suunnitteluun osallistui useita asiantuntijoita. Hallintasovellus lisäsi konttipohjaisen kehitysympäristön tehokkuutta parantamalla käyttäjäoikeuksien hallintaa, virtuaalisen kontin hallintaa ja käyttöliittymää. Lisäksi uudet hallintatyökalut lyhensivät uusien työntekijöiden koulutusaikaa 50%, mikä helpotti heidän integroitumistaan organisaatioon. Säiliöpohjaiset kehitysympäristöt varustettuina tehokkailla hallintatyökaluilla tarjoavat turvallisen, tehokkaan ja yhtenäisen alustan laajamittaiseen ohjelmistokehitykseen. Virtuaalisissa konteissa on myös potentiaalia tulevaisuuden parannuksiin energiansäästöstrategioissa ja organisaation työmenetelmien harmonisoinnissa ja integroinnissa

Thesis

This thesis details the design and development of a new messaging system for use in the mobile space. This messaging system consists of one back-end server, an API, a proxy server, client components, and a website. Developing such a system for the mobile space is a challenge, however, due to the unique characteristics found in the mobile space. Solutions to overcome these challenges are derived from RESTful web services and cloud computing technologies. Furthermore, the HTTP and CoAP protocols are explored for use in this messaging system. Experiments are then conducted to derive the most optimal protocol. For the purposes of testing this messaging system, two adaptive application management features are developed and provided through the system to the mobile development community. The rst feature is GUI Menu Ordering, which allows developers to adapt their application menu's automatically depending on user usage. The second feature is Proficiency User Modeling, which allows developers to automatically con gure their applications depending on user use behavior style. Results show the successful development of an event messaging system. In terms of the protocols CoAP surpasses HTTP in terms of performance and data consumption. However, the addition of a required CoAP proxy server a ects performance and client/server data consumption. Thus CoAP becomes slower than HTTP, but consumes less data if only the client data is measured. Furthermore, results show that if encryption is used there is an a ect. CoAP with encryption remains faster than HTTPS, even with a CoAP proxy server

Software Testing may be a method, that involves, death penalty of a software system program/application and finding all errors or bugs therein program/application in order that the result is going to be a defect-free software system. Quality of any software sys-tem will solely be acknowledged through means that of testing (software testing). Through the advancement of technology round the world, there inflated the quantity of verification techniques and strategies to check the software system before it goes to production and astray to promote. Automation Testing has created its impact within the testing method. Now-a-days, most of the software system testing is finished with the automation tools that not solely lessens the quantity of individuals operating around that software system however additionally the errors which will be loose through the eyes of the tester. Automation take look acting contains test cases that make the work simple to capture totally different eventualities and store them. Therefore, software sys-tem automation testing method plays a significant role within the software system test-ing success. This study aims in knowing differing kinds of software system testing, soft-ware system testing techniques and tools and to match manual testing versus automa-tion testing

Management, design and developement of a mesh generation environment using open source software

In this paper we present an object oriented implementation of a general-purpose mesh generation environment for geometry-based simulations. The aim of this application is to unify available legacy code and new research algorithms in only one mesh generation suite. We focus in two aspects that can be of the general interest for managers, designers and developers of similar projects. On the one hand, we analyze the software engineering practices that we have followed in the management and development process. In addition, we detail and discuss the Open Source tools and libraries that we have used. On the other hand, we discuss the design and the data structure of the environment. In particular, we first summarize the topological and geometrical representation. Second, we detail our implementation of the hierarchical mesh generation structure. Third we present our design to mediate collaboration between classes. Finally, we present some of the mesh generation features to show the capabilities of the environment

Survey of Technologies for Web Application Development

Web-based application developers face a dizzying array of platforms, languages, frameworks and technical artifacts to choose from. We survey, classify, and compare technologies supporting Web application development. The classification is based on (1) foundational technologies; (2)integration with other information sources; and (3) dynamic content generation. We further survey and classify software engineering techniques and tools that have been adopted from traditional programming into Web programming. We conclude that, although the infrastructure problems of the Web have largely been solved, the cacophony of technologies for Web-based applications reflects the lack of a solid model tailored for this domain.Comment: 43 page
