    2006-01-01

    Full Text Available Abstract Background Robust, programmatically accessible biomedical information services that syntactically and semantically interoperate with other resources are challenging to construct. Such systems require the adoption of common information models, data representations and terminology standards as well as documented application programming interfaces (APIs. The National Cancer Institute (NCI developed the cancer common ontologic representation environment (caCORE to provide the infrastructure necessary to achieve interoperability across the systems it develops or sponsors. The caCORE Software Development Kit (SDK was designed to provide developers both within and outside the NCI with the tools needed to construct such interoperable software systems. Results The caCORE SDK requires a Unified Modeling Language (UML tool to begin the development workflow with the construction of a domain information model in the form of a UML Class Diagram. Models are annotated with concepts and definitions from a description logic terminology source using the Semantic Connector component. The annotated model is registered in the Cancer Data Standards Repository (caDSR using the UML Loader component. System software is automatically generated using the Codegen component, which produces middleware that runs on an application server. The caCORE SDK was initially tested and validated using a seven-class UML model, and has been used to generate the caCORE production system, which includes models with dozens of classes. The deployed system supports access through object-oriented APIs with consistent syntax for retrieval of any type of data object across all classes in the original UML model. The caCORE SDK is currently being used by several development teams, including by participants in the cancer biomedical informatics grid (caBIG program, to create compatible data services. caBIG compatibility standards are based upon caCORE resources, and thus the caCORE SDK has

    Full Text Available Programs in education and business often require learners to develop and demonstrate competence in specified areas and then be able to effectively apply this knowledge. One method to aid in developing a skill set in these areas is through the use of software simulations. These simulations can be used for learner demonstrations of competencies in a specified course as well as a review of the basic skills at the beginning of subsequent courses. The first section of this paper discusses ToolBook, the software used to develop our software simulations. The second section discusses the process of developing software simulations. The third part discusses how we have used software simulations to assess student knowledge of research design by providing simulations that allow the student to practice using SPSS and Excel.

    An Ultra-Wideband (UWB) two-cluster Angle of Arrival (AOA) tracking prototype system is currently being developed and tested at NASA Johnson Space Center for space exploration applications. This talk discusses the software development efforts for this UWB two-cluster AOA tracking system. The role the software plays in this system is to take waveform data from two UWB radio receivers as an input, feed this input into an AOA tracking algorithm, and generate the target position as an output. The architecture of the software (Input/Output Interface and Algorithm Core) will be introduced in this talk. The development of this software has three phases. In Phase I, the software is mostly Matlab driven and calls C++ socket functions to provide the communication links to the radios. This is beneficial in the early stage when it is necessary to frequently test changes in the algorithm. Phase II of the development is to have the software mostly C++ driven and call a Matlab function for the AOA tracking algorithm. This is beneficial in order to send the tracking results to other systems and also to improve the tracking update rate of the system. The third phase is part of future work and is to have the software completely C++ driven with a graphics user interface. This software design enables the fine resolution tracking of the UWB two-cluster AOA tracking system.

    Astronomers know that their research requires writing, adapting, and documenting computer software. Furthermore, they often have to learn new computer languages and figure out how existing programs work without much documentation or guidance and with extreme time pressure. These are all skills that can lead to a software development job, but recruiters and employers probably won't know that. I will discuss all the highly useful experience that astronomers may not know that they already have, and how to explain that knowledge to others when looking for non-academic software positions. I will also talk about some of the pitfalls I have run into while interviewing for jobs and working as a developer, and encourage you to embrace the curiosity employers might have about your non-standard background.

  6. Development of software phantoms for software validation

    International Nuclear Information System (INIS)

    Nuclear medicine software is expected to meet certain criteria. The specifications are frequently not available to the user and, as a consequence, the performance of a particular software package may not meet the users' expectations. Under most circumstances this may be evident immediately, but frequently the user will assume certain specifications based upon the clinical procedure that is being performed, and assume that the software should function in a certain fashion to give the value of a desired parameter. To this end, it is useful to have a number of software phantoms which can act as standard data sets for validation of the software and ensure that the results obtained do meet expectations. A number of problems surround the development of a set of software phantoms that can be transported between different systems. One solution is the creation of mathematical phantoms, in which case algorithms or source code may be transportable. This paper describes four such mathematical phantoms that have been used to validate an ejection fraction and Fourier analysis package. This particular software package has been found lacking in several respects, none of which would have been evident from the documentation provided. (author). 12 refs, 4 figs

    A JPL-created set of standard processes is to be used throughout the lifecycle of software development. These SDSPs cover a range of activities, from management and engineering activities, to assurance and support activities. These processes must be applied to software tasks per a prescribed set of procedures. JPL s Software Quality Improvement Project is currently working at the behest of the JPL Software Process Owner to ensure that all applicable software tasks follow these procedures. The SDSPs are captured as a set of 22 standards in JPL s software process domain. They were developed in-house at JPL by a number of Subject Matter Experts (SMEs) residing primarily within the Engineering and Science Directorate, but also from the Business Operations Directorate and Safety and Mission Success Directorate. These practices include not only currently performed best practices, but also JPL-desired future practices in key thrust areas like software architecting and software reuse analysis. Additionally, these SDSPs conform to many standards and requirements to which JPL projects are beholden.

  20. Safety critical software development qualification

    International Nuclear Information System (INIS)

    With the increasing use of digital systems in control applications, customers must acquire appropriate expectations for software development and quality assurance procedures. Purchasers and users of digital systems need to understand the benefits to the supplier of effective quality systems. These systems consist not only of procedures but tools that enable automation. Without the use of automation, quality can not be assured. A software and systems quality program starts with the documents you are very familiar with. But these documents must define more than the final system. They must address specific development environment characteristics and testing capabilities. Starting with the RFP, some of the items that should be introduced are Software Configuration Management, regression testing and defect tracking. The digital system customer is in the best position to enforce the use of software and systems quality programs by including them in project requirements as early as the Purchase Order. The customer's understanding of the full scope and implementation of a software quality program is essential to achieving the quality necessary in nuclear projects, and, incidentally, completing those projects on schedule.

    2015-01-01

    What are the ingredients of high-performing software? Software development, especially for large high-performance systems, is one the most complex tasks mankind has ever tried. Technological change leads to huge opportunities but challenges our old ways of working. Processing large data sets, possibly in real time or with other tight computational constraints, requires an efficient solution architecture. Efficiency requirements span from the distributed storage and large-scale organization of computation and data onto the lowest level of processor and data bus behavior. Integrating performance behavior over these levels is especially important when the computation is resource-bounded, as it is in numerics: physical simulation, machine learning, estimation of statistical models, etc. For example, memory locality and utilization of vector processing are essential for harnessing the computing power of modern processor architectures due to the deep memory hierarchies of modern general-purpose computers. As a r...

  17. Accelerator Operators and Software Development

    International Nuclear Information System (INIS)

    At Thomas Jefferson National Accelerator Facility, accelerator operators perform tasks in their areas of specialization in addition to their machine operations duties. One crucial area in which operators contribute is software development. Operators with programming skills are uniquely qualified to develop certain controls applications because of their expertise in the day-to-day operation of the accelerator. Jefferson Lab is one of the few laboratories that utilizes the skills and knowledge of operators to create software that enhances machine operations. Through the programs written; by operators, Jefferson Lab has improved machine efficiency and beam availability. Because many of these applications involve automation of procedures and need graphical user interfaces, the scripting language Tcl and the Tk toolkit have been adopted. In addition to automation, some operator-developed applications are used for information distribution. For this purpose, several standard web development tools such as perl, VBScript, and ASP are used. Examples of applications written by operators include injector steering, spin angle changes, system status reports, magnet cycling routines, and quantum efficiency measurements. This paper summarizes how the unique knowledge of accelerator operators has contributed to the success of the Jefferson Lab control system. *This work was supported by the U.S. DOE contract No. DE-AC05-84-ER40150

    Full Text Available Agile development reduces the risk of developing low quality software in the first place by minimizing defects. In agile software development formal defect management processes help to build quality software. The core purpose of defect management is to make the software more effective and efficient in order to increase its quality. There are several methods for handling defects like defect prevention, defect discovery and resolution which are used by software developers and testers. Refactoring keeps the system clean by identifying and removing quality defects. To gain the full confidence of the customer defect management should be involved at every stage of development. Agile methodologies focus on delivering the software in form of short iterations. Thus each iteration helps to overcome defects and leads better development and end user satisfaction. This study paints the picture of handling the software defects using agile based Software Development Process.

    YAM is a software development framework with tools for facilitating the rapid development and integration of software in a concurrent software development environment. YAM provides solutions for thorny development challenges associated with software reuse, managing multiple software configurations, the development of software product-lines, multiple platform development and build management. YAM uses release-early, release-often development cycles to allow developers to incrementally integrate their changes into the system on a continual basis. YAM facilitates the creation and merging of branches to support the isolated development of immature software to avoid impacting the stability of the development effort. YAM uses modules and packages to organize and share software across multiple software products. It uses the concepts of link and work modules to reduce sandbox setup times even when the code-base is large. One side-benefit is the enforcement of a strong module-level encapsulation of a module s functionality and interface. This increases design transparency, system stability as well as software reuse. YAM is in use by several mid-size software development teams including ones developing mission-critical software.

    Full Text Available Lymphomas are the fifth most common cancer in United States with numerous histological subtypes. Integrating existing clinical information on lymphoma patients provides a platform for understanding biological variability in presentation and treatment response and aids development of novel therapies. We developed a cancer Biomedical Informatics Grid™ (caBIG™ Silver level compliant lymphoma database, called the Lymphoma Enterprise Architecture Data-system™ (LEAD™, which integrates the pathology, pharmacy, laboratory, cancer registry, clinical trials, and clinical data from institutional databases. We utilized the Cancer Common Ontological Representation Environment Software Development Kit (caCORE SDK provided by National Cancer Institute’s Center for Bioinformatics to establish the LEAD™ platform for data management. The caCORE SDK generated system utilizes an n-tier architecture with open Application Programming Interfaces, controlled vocabularies, and registered metadata to achieve semantic integration across multiple cancer databases. We demonstrated that the data elements and structures within LEAD™ could be used to manage clinical research data from phase 1 clinical trials, cohort studies, and registry data from the Surveillance Epidemiology and End Results database. This work provides a clear example of how semantic technologies from caBIG™ can be applied to support a wide range of clinical and research tasks, and integrate data from disparate systems into a single architecture. This illustrates the central importance of caBIG™ to the management of clinical and biological data.

    Hartrum, Thomas C.; Lamont, Gary B.

    1987-01-01

    The generation of a set of tools for software lifecycle is a recurring theme in the software engineering literature. The development of such tools and their integration into a software development environment is a difficult task because of the magnitude (number of variables) and the complexity (combinatorics) of the software lifecycle process. An initial development of a global approach was initiated in 1982 as the Software Development Workbench (SDW). Continuing efforts focus on tool development, tool integration, human interfacing, data dictionaries, and testing algorithms. Current efforts are emphasizing natural language interfaces, expert system software development associates and distributed environments with Ada as the target language. The current implementation of the SDW is on a VAX-11/780. Other software development tools are being networked through engineering workstations.

  18. DEVELOPING SOFTWARE FOR CORPUS RESEARCH

    Directory of Open Access Journals (Sweden)

    Oliver Mason

    2008-06-01

    Full Text Available Despite the central role of the computer in corpus research, programming is generally not seen as a core skill within corpus linguistics. As a consequence, limitations in software for text and corpus analysis slow down the progress of research while analysts often have to rely on third party software or even manual data analysis if no suitable software is available. Apart from software itself, data formats are also of great importance for text processing. But again, many practitioners are not very aware of the options available to them, and thus idiosyncratic text formats often make sharing of resources difficult if not impossible. This article discusses some issues relating to both data and processing which should aid researchers to become more aware of the choices available to them when it comes to using computers in linguistic research. It also describes an easy way towards automating some common text processing tasks that can easily be acquired without knowledge of actual computer programming.

    The interdependence of the U.S.-Japanese economies makes it imperative that we in the United States understand how business and technology developments take place in Japan. We can gain insight into these developments in software engineering by studying the context in which Japanese software is developed, the practices that are used, the problems encountered, the setting surrounding these problems, and the resolution of these problems. Context includes the technological and sociological characteristics of the software development environment, the software processes applied, personnel involved in the development process, and the corporate and social culture surrounding the development. Presented in this paper is a summary of results of a study that addresses these issues. Data for this study was collected during a three month visit to Japan where the author interviewed 20 software managers representing nine companies involved in developing software in Japan. These data are compared to similar data from the United States in which 12 managers from five companies were interviewed.

    Full Text Available The paper is aimed at depicting the ISDF software development methodology by emphasizing quality management and software development lifecycle. The ISDF methodology was built especially for innovative software development projects. The ISDF methodology was developed empirically by trial and error in the process of implementing multiple innovative projects. The research process began by analysing key concepts like innovation and software development and by settling the important dilemma of what makes a web application innovative. Innovation in software development is presented from the end-user, project owner and project manager’s point of view. The main components of a software development methodology are identified. Thus a software development methodology should account for people, roles, skills, teams, tools, techniques, processes, activities, standards, quality measuring tools, and team values. Current software development models are presented and briefly analysed. The need for a dedicated innovation oriented software development methodology is emphasized by highlighting shortcomings of current software development methodologies when tackling innovation. The ISDF methodology is presented in the context of developing an actual application. The ALHPA application is used as a case study for emphasizing the characteristics of the ISDF methodology. The development life cycle of the ISDF methodology includes research, planning, prototyping, design, development, testing, setup and maintenance. Artefacts generated by the ISDF methodology are presented. Quality is managed in the ISDF methodology by assessing compliance, usability, reliability, repeatability, availability and security. In order to properly asses each quality component a dedicated indicator is built. A template for interpreting each indicator is provided. Conclusions are formulated and new related research topics are submitted for debate.

SDA orchestrates the performance of work required to complete all process tasks in the correct sequence. The software then notifies team members when they may begin work on their assigned tasks and provides the tools, instructions, reference materials, and supportive artifacts that allow users to compliantly perform the work. A combination of technology components captures and enacts any software process use to support the software lifecycle. It creates an adaptive workflow environment that can be modified as needed. SDA achieves software process automation through a Business Process Management (BPM) approach to managing the software lifecycle for mission-critical projects. It contains five main parts: TieFlow (workflow engine), Business Rules (rules to alter process flow), Common Repository (storage for project artifacts, versions, history, schedules, etc.), SOA (interface to allow internal, GFE, or COTS tools integration), and the Web Portal Interface (collaborative web environment

    Many approaches to designing software systems have been developed for use in commercial or business environments. These development methods and procedures have improved dramatically over the last ten years although it is only recently that these have been employed in scientific and technological applications. Many of these implementations have been unsuccessful because the design methodology has been divorced from the practical requirements of the industry in which the software system is to operate. This paper discusses a modern approach to software development which directly relates to an engineering environment and which is designed to satisfy practical criteria of acceptability of the software when delivered to the petroleum engineer. Since all field developments nowadays rely heavily on associated software systems, the approach presented here can lead to improved mechanical systems reliability and shorter development/design cycles.

    2010-01-01

    Distribution of software development is becoming more and more common in order to save the production cost and reduce the time to market. Large geographical distance, different time zones and cultural differences in distributed software development (DSD) leads to weak communication which adversely affects the project. Using agile practices for distributed development is also gaining momentum in various organizations to increase the quality and performance of the project. This paper explores the intersection of these two significant trends for software development i.e. DSD and agile. We discuss the challenges faced by geographically distributed agile teams and proven practices to address these issues, which will help in building a successful distributed team.

  15. Strategies for Developing China's Software Industry

    Directory of Open Access Journals (Sweden)

    Mingzhi Li

    2003-01-01

    Full Text Available The software industry is deemed an ideal target for a developing country to integrate into the world information and communications technology (ICT market. On the one hand the industry is labor intensive, and the developing countries have a large labor surplus; on the other hand, it is a worldwide trend for developed countries to outsource a vast amount of low-end, software-related tasks to the low-cost countries and regions, which fits into some developing countries’ caliber nicely. India has often been cited as the role model for a developing country to tap into the world software market for its continuous success in the software export sector. In comparison, China’s software industry is still negligible in the world despite its sustained high economic growth rate since the economic reform took off in the late 1970s.This paper aims at examining strategies for developing China’s software industry. We use India as a reference because of the similarities of the two countries’ stages of economic development and the clear divergence in their ICT structures and development paths. Although the language barrier has often been singled out as the major obstacle for China’s software exports, we believe the major reasons for its underdevelopment can be ascribed to the following factors. On the national level, the government attention has been skewed toward the hardware sector in the ICT industry, and there is no clear national vision for the strategic direction for the software industry.On the industry and ªrm level, software development has been regarded as the art of individual creativity rather than an engineering process. As a result, the importance of quality and standards, the two important critical factors in software development, have been largely neglected. Perhaps an even more fundamental factor lies in the deeply rooted notion that software is an attachment to the hardware and should be a free product. The lack of intellectual

    Full Text Available Software developing companies work in a competitive market and are often challenged to make business decisions with impact on competitiveness. Models accessing maturity for software development processes quality, such as CMMI and MPS-BR, comprise process measurements systems (PMS. However, these models are not necessarily suitable to support business decisions, neither to achieve strategic goals. The objective of this work is to analyze how the PMS of software development projects could support business strategies for software developing companies. Results taken from this work show that PMS results from maturity models for software processes can be suited to help evaluating operating capabilities and supporting strategic business decisions.

    2011-01-01

    Full Text Available This paper describes a case study of how a game project using the XNA Game Studio from Microsoft was implemented in a software architecture course. In this project, university students have to construct and design a type of software architecture, evaluate the architecture, implement an application based on the architecture, and test this implementation. In previous years, the domain of the software architecture project has been a robot controller for navigating a maze. Robot controller was chosen as the domain for the project, as there exist several papers and descriptions on reference architectures for managing mobile robots. This paper describes the changes we had to make to introduce an XNA game development project to the software architecture course, and our experiences from running a software architecture project focusing on game development and XNA. The experiences described in this paper are based on feedback from the course staff, the project reports of the students, and a mandatory course evaluation. The evaluation shows among other things that the majority of the students preferred the game project to the robot project, that XNA was considered to be suitable platform for a software architecture project, that the students found it useful to learn XNA and C#, and that some students were carried away when developing the game in the software architecture project.

  17. Developing engineering software -- A fundamental approach

    Energy Technology Data Exchange (ETDEWEB)

    Wellman, J. [Black and Veatch, Kansas City, MO (United States)

    1998-12-31

    The rapid advanced in computer hardware and software coupled with the power industry`s right-sizing have created a unique opportunity for companies to gain a competitive advantage through custom software development. This custom development can standardize repetitive processes, ensure precise data, and enhance personal productivity. However, if the development is not managed properly, the process quickly becomes a budget-consuming project that delivers none of the anticipated rewards. Engineering software often falls into this realm of expensive and non-productive development. Most power engineers are excellent mechanical, electrical, chemical, civil, or plant engineers, but they have little software development experience. They spend much of their time keeping current with their disciplines and do not have the time or resources to keep current with the rapidly changing computer field. As a result, when a company tells the engineering staff to work smarter, not harder, the power plant engineering often finds himself trying to develop a simple program to help with his repetitive tasks. Since he is not familiar with structured software development, he often spends significant effort, and therefore significant funds performing a trial-and-error development approach. This paper suggests a structured process for small to medium engineering software projects that can be handled with either internal or contract developers. This process will basically follow familiar engineering fundamentals: (1) define the problem--determine the program scope; (2) state the assumptions--determine the necessary input and output; (3) develop a solution--write the program; (4) evaluate the results--test and validate the program; (5) state the conclusions--document the features and limitations. Though these steps seem clear, this paper presents some common pitfalls and how to avoid them.

Stakeholders are distributed located that brings into several challenges to coordinate and collaborate effectively. Scrum is one the widely practiced agile methodologies. Majority of the software development companies showed a great interest from last few years to apply Scrum methodology in distributed development to solve the coordination and communication problems. Although Scrum contains good features and strengths but still there are improvement possibilities to solve the problems of coordination and collaboration in GSD. Majority of software development companies face the problems of coordination and communication in GSD projects. This paper proposes a novel solution to mitigate the coordination and communication challenges of GSD projects. The survey is used as a research methodology to evaluate the proposed solution. The proposed solution is supported by 62.24%. We anticipate that the proposed solution will help the software development companies to mitigate the coordination and communication challenges of GSD projects.

Designing and developing such a system in a distributed fashion requires proper tools and the setup of an environment to allow for ecient detection and tracking of interface and integration issues in particular in a timely way. Agile development can provide much faster feedback mechanisms and also much tighter collaboration between the customer (scientist) and the developer. Continuous integration and continuous deployment on the other hand can provide much faster feedback of integration issues from the system level to the subsystem developers. This paper describes the results obtained from trialing a potential SKA development environment based on existing science software development processes like ALMA, the expected distribution of the groups potentially involved in the SKA development and experience gained in the development of large scale commercial software projects.

    All software development processes include steps where several alternatives induce a choice, a decision-making. Sometimes, methodologies offer a way to make decisions. However, in a lot of cases, the arguments to carry out the decision are very poor and the choice is made in an intuitive and hazardous way. The aim of our work is to offer a scientifically founded way to guide the engineer through tactical choices with the application of multicriteria methods in software development processes. This approach is illustrated with three cases: risks, use cases and tools within Rational Unified Process.

    Full Text Available The article considers the specifics of a model oriented approach to software development based on the usage of Model Driven Architecture (MDA, Model Driven Software Development (MDSD and Model Driven Development (MDD technologies. Benefits of this approach usage in the software development industry are described. The main emphasis is put on the system design, automated code generation for large systems, verification, proof of system properties and reduction of bug density. Drawbacks of the approach are also considered. The approach proposed in the article is specific for industrial software systems development. These systems are characterized by different levels of abstraction, which is used on modeling and code development phases. The approach allows to detail the model to the level of the system code, at the same time store the verified model semantics and provide the checking of the whole detailed model. Steps of translating abstract data structures (including transactions, signals and their parameters into data structures used in detailed system implementation are presented. Also the grammar of a language for specifying rules of abstract model data structures transformation into real system detailed data structures is described. The results of applying the proposed method in the industrial technology are shown.The article is published in the authors’ wording.

    This document describes a Software Development Methodology for High Consequence Systems. A High Consequence System is a system whose failure could lead to serious injury, loss of life, destruction of valuable resources, unauthorized use, damaged reputation or loss of credibility or compromise of protected information. This methodology can be scaled for use in projects of any size and complexity and does not prescribe any specific software engineering technology. Tasks are described that ensure software is developed in a controlled environment. The effort needed to complete the tasks will vary according to the size, complexity, and risks of the project. The emphasis of this methodology is on obtaining the desired attributes for each individual High Consequence System.

    2009-12-01

    Full Text Available As an answer to today’s growing challenges in software industry, wide spectrum of new approaches of software development has occurred. One prominent direction is currently most promising software development paradigm called Model Driven Development (MDD. Despite a lot of skepticism and problems, MDD paradigm is being used and improved to accomplish many inherent potential benefits. In the methodological approach of software development it is necessary to use some kind of development process. Modern methodologies can be classified into two main categories: formal or heavyweight and agile or lightweight. But when it is a question about MDD and development process for MDD, currently known methodologies are very poor or better said they don't have any explanation of MDD process. As the result of research, in this paper, author examines the possibilities of using existing modern software methodologies in context of MDD paradigm.

    The Controls software for the Large Hadron Collider (LHC) at CERN, with more than 150 millions lines of code, resides amongst the largest known code bases in the world1. Industry has been applying Agile software engineering techniques for more than two decades now, and the advantages of these techniques can no longer be ignored to manage the code base for large projects within the accelerator community. Furthermore, CERN is a particular environment due to the high personnel turnover and manpower limitations, where applying Agile processes can improve both, the codebase management as well as its quality. This paper presents the successful application of the Agile software development process Scrum for machine protection systems at CERN, the quality standards and infrastructure introduced together with the Agile process as well as the challenges encountered to adapt it to the CERN environment.

    Brogley, Aaron C.

    2013-01-01

    The Morpheus project is an autonomous robotic testbed currently in development at NASA's Johnson Space Center (JSC) with support from other centers. Its primary objectives are to test new 'green' fuel propulsion systems and to demonstrate the capability of the Autonomous Lander Hazard Avoidance Technology (ALHAT) sensor, provided by the Jet Propulsion Laboratory (JPL) on a lunar landing trajectory. If successful, these technologies and lessons learned from the Morpheus testing cycle may be incorporated into a landing descent vehicle used on the moon, an asteroid, or Mars. In an effort to reduce development costs and cycle time, the project employs lean development engineering practices in its development of flight and simulation software. The Morpheus simulation makes use of existing software packages where possible to reduce the development time. The development and testing of flight software occurs primarily through the frequent test operation of the vehicle and incrementally increasing the scope of the test. With rapid development cycles, risk of loss of the vehicle and loss of the mission are possible, but efficient progress in development would not be possible without that risk.

    Improving software process to achieve high quality in a software development organization is the key factor to success. Bangladeshi software firms have not experienced much in this particular area in comparison to other countries. The ISO 9001 and CMM standard has become a basic part of software development. The main objectives of our study are: 1) To understand the software development process uses by the software developer firms in Bangladesh 2) To identify the development practices based on established quality standard and 3) To establish a standardized and coherent process for the development of software for a specific project. It is revealed from this research that software industries of Bangladesh are lacking in target set for software process and improvement, involvement of quality control activities, and standardize business expertise practice. This paper investigates the Bangladeshi software industry in the light of the above challenges.

    Full Text Available Why is it so difficult to learn to develop software? This question has been trying to answer for a long time, but has not yet found a solution to this issue. Moreover, it tends to confuse development with programming, and this also creates problems to elucidate the question. In an era in which urgently required improve the quality, and reliability, and safety of software it becomes urgent to potentiate or develop skills and abilities in professionals to meet these needs. But students are not interested in making careers involving these concepts, they prefer other less demanding and easier to achieve a certification. This article attempts to answer the question and present some suggestions for overcoming this difficulty.

  8. Documenting the decision structure in software development

    Science.gov (United States)

    Wild, J. Christian; Maly, Kurt; Shen, Stewart N.

    1990-01-01

    Current software development paradigms focus on the products of the development process. Much of the decision making process which produces these products is outside the scope of these paradigms. The Decision-Based Software Development (DBSD) paradigm views the design process as a series of interrelated decisions which involve the identification and articulation of problems, alternates, solutions and justifications. Decisions made by programmers and analysts are recorded in a project data base. Unresolved problems are also recorded and resources for their resolution are allocated by management according to the overall development strategy. This decision structure is linked to the products affected by the relevant decision and provides a process oriented view of the resulted system. Software maintenance uses this decision view of the system to understand the rationale behind the decisions affecting the part of the system to be modified. D-HyperCase, a prototype Decision-Based Hypermedia System is described and results of applying the DBSD approach during its development are presented.

  9. Embracing Open Software Development in Solar Physics

    2012-12-01

    We discuss two ongoing software projects in solar physics that have adopted best practices of the open source software community. The first, the Helioviewer Project, is a powerful data visualization tool which includes online and Java interfaces inspired by Google Maps (tm). This effort allows users to find solar features and events of interest, and download the corresponding data. Having found data of interest, the user now has to analyze it. The dominant solar data analysis platform is an open-source library called SolarSoft (SSW). Although SSW itself is open-source, the programming language used is IDL, a proprietary language with licensing costs that are prohibative for many institutions and individuals. SSW is composed of a collection of related scripts written by missions and individuals for solar data processing and analysis, without any consistent data structures or common interfaces. Further, at the time when SSW was initially developed, many of the best software development processes of today (mirrored and distributed version control, unit testing, continuous integration, etc.) were not standard, and have not since been adopted. The challenges inherent in developing SolarSoft led to a second software project known as SunPy. SunPy is an open-source Python-based library which seeks to create a unified solar data analysis environment including a number of core datatypes such as Maps, Lightcurves, and Spectra which have consistent interfaces and behaviors. By taking advantage of the large and sophisticated body of scientific software already available in Python (e.g. SciPy, NumPy, Matplotlib), and by adopting many of the best practices refined in open-source software development, SunPy has been able to develop at a very rapid pace while still ensuring a high level of reliability. The Helioviewer Project and SunPy represent two pioneering technologies in solar physics - simple yet flexible data visualization and a powerful, new data analysis environment. We

    Full Text Available Software exports have the potential to make a significant contribution to the economies of developing countries and to the global IT industry. Developing countries have demonstrated a comparative advantage in this export sector and the global IT industry can benefit from this developing country advantage. Today, IT is high investment, high risk, and high reward and has graduated from being a critical support function to a key partner, sometimes responsible for directing the strategy of an enterprise. Business and technology managers cannot afford to miss the opportunities provided by the comparative advantage of developing countries in the IT arena.

    Martins, Wellington; de Sousa, Daniel; Proite, Karina; Guimarães, Patrícia; Moretzsohn, Marcio; Bertioli, David

    2006-01-01

    Microsatellites are repeated small sequence motifs that are highly polymorphic and abundant in the genomes of eukaryotes. Often they are the molecular markers of choice. To aid the development of microsatellite markers we have developed a module that integrates a program for the detection of microsatellites (TROLL), with the sequence assembly and analysis software, the Staden Package. The module has easily adjustable parameters for microsatellite lengths and base pair quality control. Starting with large datasets of unassembled sequence data in the form of chromatograms and/or text data, it enables the creation of a compact database consisting of the processed and assembled microsatellite containing sequences. For the final phase of primer design, we developed a program that accepts the multi-sequence 'experiment file' format as input and produces a list of primer pairs for amplification of microsatellite markers. The program can take into account the quality values of consensus bases, improving success rate of primer pairs in PCR. The software is freely available and simple to install in both Windows and Unix-based operating systems. Here we demonstrate the software by developing primer pairs for 427 new candidate markers for peanut. PMID:16493138

  14. Problems in software development for nuclear robotics

    International Nuclear Information System (INIS)

    Major technical problems in developing softwares for intelligent robots for future nuclear applications are explained briefly. In order that a robot can perform various kinds of complex works, it must be equipped with a high level of artificial intelligence which includes sensing functions such as visiual, auditory, tactile, proximity sensing, cognitive functions such as recognition of objects and understanding of working environment, decision-making functions such as work planning and control functions such as manipulator and locomotion controls. A large amount of various kinds of signals and informations must be processed with a high speed for an integrated control of these functions. It will be desirable that the computer program for controlling a robot which must run in a real-time will have a functionally hierarchical and distributed structure from the view point of software development. Parallel processing will be required from the view point of computation time. (author)

    2010-01-01

    The Math Description Engine Software Development Kit (MDE SDK) can be used by software developers to make computer-rendered graphs more accessible to blind and visually-impaired users. The MDE SDK generates alternative graph descriptions in two forms: textual descriptions and non-verbal sound renderings, or sonification. It also enables display of an animated trace of a graph sonification on a visual graph component, with color and line-thickness options for users having low vision or color-related impairments. A set of accessible graphical user interface widgets is provided for operation by end users and for control of accessible graph displays. Version 1.0 of the MDE SDK generates text descriptions for 2D graphs commonly seen in math and science curriculum (and practice). The mathematically rich text descriptions can also serve as a virtual math and science assistant for blind and sighted users, making graphs more accessible for everyone. The MDE SDK has a simple application programming interface (API) that makes it easy for programmers and Web-site developers to make graphs accessible with just a few lines of code. The source code is written in Java for cross-platform compatibility and to take advantage of Java s built-in support for building accessible software application interfaces. Compiled-library and NASA Open Source versions are available with API documentation and Programmer s Guide at http:/ / prim e.jsc.n asa. gov.

  9. Control of research oriented software development

    International Nuclear Information System (INIS)

    The Nuclear Waste Policy Act of 1982 directs the Department of Energy (DOE) to dispose permanently high level radioactive waste and civilian spent nuclear fuel by January 31, 1998. DOE has responded by creating an organizational structure that directs all the activities necessary to carry out the legislative demands. LLNL is conducting research in the earth sciences and is developing some unique computer codes to help establish the feasibility of geologic repositories for nuclear waste. LLNL has several codes under development. This paper examines the administrative and organizational measures that were and still are being undertaken in order to control the development of the two major codes. In the case of one code, the software quality assurance requirements were imposed five years after the code began its development. This required a retroactive application of requirements. The other code is still in the conceptual stages of development and here requirements can be applied as soon as the initial code design begins. Both codes are being developed by scientists, not computer programmers, and both are modeling codes, not data acquisition and reduction codes. Also the projects for which these codes are being developed have slightly different software quality assurance requirements. All these factors contribute unique difficulties in attempts to assure that the development not only results in a reliable prediction, but that whatever the reliability, it can be objectively shown to exist. The paper will examine a software management model. It will also discuss the reasons why it is felt that this particular model would stand a reasonable chance for success. The paper will then describe the way in which the model should be integrated into the existing management configuration and tradition

    2007-01-01

    Based on the empirical analysis of data contained in the International Software Benchmarking Standards Group(ISBSG) repository, this paper presents software engineering project duration models based on project effort. Duration models are built for the entire dataset and for subsets of projects developed for personal computer, mid-range and mainframeplatforms. Duration models are also constructed for projects requiring fewer than 400 person-hours of effort and for projectsre quiring more than 400 person-hours of effort. The usefulness of adding the maximum number of assigned resources as asecond independent variable to explain duration is also analyzed. The opportunity to build duration models directly fromproject functional size in function points is investigated as well.

    This paper provides an analysis of the effect of the skill/experience of the software development team on the quality of the final software product. A method for the assessment of software development team skill and experience is proposed, and was derived from a workforce management tool currently in use by the National Aeronautics and Space Administration. Using data from 26 smallscale software development projects, the team skill measures are correlated to 5 software product quality metrics from the ISO/IEC 9126 Software Engineering Product Quality standard. in the analysis of the results, development team skill is found to be a significant factor in the adequacy of the design and implementation. In addition, the results imply that inexperienced software developers are tasked with responsibilities ill-suited to their skill level, and thus have a significant adverse effect on the quality of the software product.

    The proposed project FAIR (Facility for Anti-proton and Ion Research) is an international accelerator facility of the next generation. It builds on top of the experience and technological developments already made at the existing GSI facility, and incorporate new technological concepts. The four scientific pillars of FAIR are NUSTAR (nuclear structure and astrophysics), PANDA (QCD studies with cooled beams of anti-protons), CBM (physics of hadronic matter at highest baryon densities), and APPA (atomic physics, plasma physics, and applications). The FairRoot framework used by all of the big FAIR experiments as a base for their own specific developments, provides basic functionality like IO, geometry handling etc. The challenge is to support all the different experiments with their heterogeneous requirements. Due to the limited manpower, one of the first design decisions was to (re)use as much as possible already available and tested software and to focus on the development of the framework. Beside the framework itself, the FairRoot core team also provides some software development tools. We will describe the complete set of tools in this article. The Makefiles for all projects are generated using CMake. For software testing and the corresponding quality assurance, we use CTest to generate the results and CDash as web front end. The tools are completed by subversion as source code repository and trac as tool for the complete source code management. This set of tools allows us to offer the full functionality we have for FairRoot also to the experiments based on FairRoot.

    This paper discusses the salient characteristics of analysis software and the impact of those characteristics on its development. From this discussion, it can be seen that mainstream software development processes, usually characterized as Plan Driven or Agile, are built upon assumptions that are mismatched to the development and maintenance of analysis software. We propose a novel software development framework that would match the process normally observed in the development of analysis software. In the discussion of this framework, we suggest areas of research and directions for future work. (author)

    Nordio, Martin; Estler, H -Christian

    2011-01-01

    Software development environments (IDEs) have not followed the IT industry's inexorable trend towards distribution. They do too little to address the problems raised by today's increasingly distributed projects; neither do they seize the potential benefits of the Internet, as many other kinds of IT applications have done through their move to Cloud Computing. A consequence is the continued reliance of today's IDEs on paradigms such as traditional configuration management, which were developed for earlier modes of operation and hamper distributed projects. This contribution describes a new paradigm: cloud-based development, which takes advantage of the Internet to benefit all projects, and caters to the specific needs of distributed projects. The CloudStudio IDE embodies this paradigm by enabling developers to work on a shared project repository. Configuration management becomes unobtrusive; it replaces the explicit update-modify-commit cycle, with its damaging "Big Bang" effects, by automatic history manageme...

  9. BRIDGE: A Model for Modern Software Development Process to Cater the Present Software Crisis

    CERN Document Server

    Mandal, Ardhendu

    2011-01-01

    As hardware components are becoming cheaper and powerful day by day, the expected services from modern software are increasing like any thing. Developing such software has become extremely challenging. Not only the complexity, but also the developing of such software within the time constraints and budget has become the real challenge. Quality concern and maintainability are added flavour to the challenge. On stream, the requirements of the clients are changing so frequently that it has become extremely tough to manage these changes. More often, the clients are unhappy with the end product. Large, complex software projects are notoriously late to market, often exhibit quality problems, and don't always deliver on promised functionality. None of the existing models are helpful to cater the modern software crisis. Hence, a better modern software development process model to handle with the present software crisis is badly needed. This paper suggests a new software development process model, BRIDGE, to tackle pr...

  6. Development of a Brachytherapy Software Nomogram Equivalent

    International Nuclear Information System (INIS)

    The main objective of this project is developing a software nomogram equivalent. A nomogram is a graph typically comprised of three parallel lines. Each of the lines is graduated for a different variable, often in a non-linear scale. The lines are oriented in such a manner that if a straight line is drawn connecting two of the three variables, the value of the third variable is uniquely determined by the intersection of the connecting line and the graduated line of the third variable. The value of the third variable is determined by reading the graduated scale at the point of intersection. A nomogram as applied in brachytherapy is used for determining the required amount of radioactive material to be implanted in a diseased site. A typical brachytherapy nomogram relates the average dimension of a site, the air kerma strength per source and the number of sources required for yielding a therapeutic radiation dose to the site. More sophisticated nomograms also provide scales for recommending source and needle spacings. For decades the nomogram has been clinically employed as a brachytherapy treatment planning tool. Imaging modalities such as CT and ultrasound ushered in modern image-based brachytherapy treatment planning. These modern imaging techniques dramatically advanced the state of the art of brachytherapy, often obviating the use of nomograms. Although the routine use of nomograms has decreased, there are clinical situations where nomograms still prove useful for brachytherapy treatment planning. Often times the dimensions of a tumor or tumor bed are not known prior to surgery and delineated images of the site are not available. In such situations the tumor dimensions can be measured in the OR and a nomogram applied for rapid treatment planning. By definition a nomogram is a graphical tool, which is fixed and cannot be modified. Differences of opinion and treatment philosophies exist among physicians and institutions. These varying approaches can lead to

    Rusu, Lazar; Lin, Yifeng; Hodosi, Georg

    Worldwide job market for database developers (DBDs) is continually increasing in last several years. In some companies, DBDs are organized as a special team (DBDs team) to support other projects and roles. As a new role, the DBDs team is facing a major problem that there are not any management guidelines for them. The team manager does not know which kinds of tasks should be assigned to this team and what practices should be used during DBDs work. Therefore in this paper we have developed a set of management guidelines, which includes 8 fundamental tasks and 17 practices from software development process, by using two methodologies Capability Maturity Model (CMM) and agile software development in particular Scrum in order to improve the DBDs team work. Moreover the management guidelines developed here has been complemented with practices from authors' experience in this area and has been evaluated in the case of a software company. The management guidelines for DBD teams presented in this paper could be very usefully for other companies too that are using a DBDs team and could contribute towards an increase of the efficiency of these teams in their work on software development projects.

    Science.gov (United States)

    1992-01-01

    Software development is widely considered to be a bottleneck in the development of complex systems, both in terms of development and in terms of maintenance of deployed systems. Cost of software development and maintenance can also be very high. One approach to reducing costs and relieving this bottleneck is increasing the reuse of software designs and software components. A method for achieving such reuse is a software parts composition system. Such a system consists of a language for modeling software parts and their interfaces, a catalog of existing parts, an editor for combining parts, and a code generator that takes a specification and generates code for that application in the target language. The Advanced Software Development Workstation is intended to be an expert system shell designed to provide the capabilities of a software part composition system.

  4. Software development for managing nuclear material database

    International Nuclear Information System (INIS)

    In nuclear facilities, the nuclear material control is one of the most important activities. The Brazilian National Commission of Nuclear Energy (CNEN) and the International Atomic Energy Agency (IAEA), when inspecting routinely, regards the data provided as a major safety factor. Having a control system of nuclear material that allows the amount and location of the various items to be inspected, at any time, is a key factor today. The objective of this work was to enhance the existing system using a more friendly platform of development, through the VisualBasic programming language (Microsoft Corporation), to facilitate the operation team of the reactor IEA-R1 Reactor tasks, providing data that enable a better and prompter control of the IEA-R1 nuclear material. These data have allowed the development of papers presented at national and international conferences and the development of master's dissertations and doctorate theses. The software object of this study was designed to meet the requirements of the CNEN and the IAEA safeguard rules, but its functions may be expanded in accordance with future needs. The program developed can be used in other reactors to be built in the country, since it is very practical and allows an effective control of the nuclear material in the facilities. (author)

  9. EPRI's POWERCOACH trademark software development project

    International Nuclear Information System (INIS)

    Today's complex bulk power market accounts for an estimated $35 billion in transactions a year, significantly more than a decade ago. With the increased levels of non-utility generation and changing strategies in the utility industry, it is anticipated that the trend toward rapid growth in the bulk power market will continue. This market has evolved from an ad hoc residual market to one that in some respects stands at par with the retail market in the plans of many utilities. The bulk power market is not based on the obligation to serve to the same extent as retail markets. Utility participation in this market is therefore purely voluntary. This freedom of action or inaction in the bulk power market actually renders corporate decision-making, investment related or operational, more complicated in many respects than in retail markets. Examples of the burgeoning uncertainties affecting the bulk power market include the rapid expansion of transactions undertaken through power pools, and the impact on utility planning and operations brought about by the abundance and price attractiveness of power available for flexible periods. These uncertainties present an ideal opportunity to employ state-of-the-art analytical models to facilitate the effective use of utility assets to foster the efficient functioning of the entire bulk power market. This paper will focus on the POWERCOACH methodology for short-term bulk power transaction analysis under conditions of uncertainty. In August 1992, UPMP began a seventeen month project to convert POWERCOACH from a methodology to a fully functional, commercial software package. UPMP is developing the POWERCOACH software with the extensive, direct involvement of thirty EPRI member utilities. A synopsis of POWERCOACH is presented

    This is the second in a series of reports pertaining to progress in the Advanced Software Development and Commercialization Project, a collaborative effort between the Center for Supercomputing Research and Development of the University of Illinois and the Computing and Telecommunications Divisions of Argonne National Laboratory. The purpose of this work is to apply techniques of parallel computing many of which were pioneered by University of Illinois researchers to mature computational fluid dynamics (CFD) and structural dynamics (SC) computer codes developed at Argonne. The collaboration in this project brings this unique combination of expertise to bear, for the first time, on industrially important problems. By so doing, it will expose the strengths and weaknesses of existing techniques for parallelizing programs and will identify those problems that need to be solved in order to enable widespread production use of parallel computers. Secondly, the increased efficiency of the CFD and SD codes themselves will enable the simulation of larger, more accurate engineering models that involve fluid and structural dynamics. Such an enhanced capability is fundamental to industrial efficiency and competitiveness, and could serve as an exemplary model for similar future activities. 21 refs, 5 figs., 31 tabs.

    This is the first of a series of reports pertaining to progress in the Advanced Software Development and Commercialization Project, a joint collaborative effort between the Center for Supercomputing Research and Development of the University of Illinois and the Computing and Telecommunications Division of Argonne National Laboratory. The purpose of this work is to apply techniques of parallel computing that were pioneered by University of Illinois researchers to mature computational fluid dynamics (CFD) and structural dynamics (SD) computer codes developed at Argonne. The collaboration in this project will bring this unique combination of expertise to bear, for the first time, on industrially important problems. By so doing, it will expose the strengths and weaknesses of existing techniques for parallelizing programs and will identify those problems that need to be solved in order to enable wide spread production use of parallel computers. Secondly, the increased efficiency of the CFD and SD codes themselves will enable the simulation of larger, more accurate engineering models that involve fluid and structural dynamics. In order to realize the above two goals, we are considering two production codes that have been developed at ANL and are widely used by both industry and Universities. These are COMMIX and WHAMS-3D. The first is a computational fluid dynamics code that is used for both nuclear reactor design and safety and as a design tool for the casting industry. The second is a three-dimensional structural dynamics code used in nuclear reactor safety as well as crashworthiness studies. These codes are currently available for both sequential and vector computers only. Our main goal is to port and optimize these two codes on shared memory multiprocessors. In so doing, we shall establish a process that can be followed in optimizing other sequential or vector engineering codes for parallel processors.

  3. On the polynomial dynamic system approach to software development

    WANG Xiangyun; LI Yongchao; CAI Kaiyuan

    2004-01-01

    In this paper the development of reactive software is transformed into a control problem, and the supervisory control theory for discrete event dynamic systems is suggested to solve this control problem. The operating environment under consideration is viewed as a controlled plant, the software under development as the corresponding controller, and the software requirements as the corresponding control objective. This idea leads to a constructive approach of software design, which ensures properties required a priori of the software under development. In this way the validation of the software under development is reduced to the validation of properties independent of implementation process. We reveal the inconsistence in using the concept of reachability to specify software requirements and clarify six different definitions of reachability. Two different definitions of invariance for specifying software requirements are also clarified.We then show how to synthesize the required controller or obtain software design solutions if the underlying software requirements are specified by several new combinations of reachability and invariance. The topic of this paper falls into the scope of software cybernetics that explores the interplay between software and control.

    Science.gov (United States)

    Graziotin, Daniel; Wang, Xiaofeng; Abrahamsson, Pekka

    2014-01-01

    For more than thirty years, it has been claimed that a way to improve software developers' productivity and software quality is to focus on people and to provide incentives to make developers satisfied and happy. This claim has rarely been verified in software engineering research, which faces an additional challenge in comparison to more traditional engineering fields: software development is an intellectual activity and is dominated by often-neglected human factors (called human aspects in software engineering research). Among the many skills required for software development, developers must possess high analytical problem-solving skills and creativity for the software construction process. According to psychology research, affective states-emotions and moods-deeply influence the cognitive processing abilities and performance of workers, including creativity and analytical problem solving. Nonetheless, little research has investigated the correlation between the affective states, creativity, and analytical problem-solving performance of programmers. This article echoes the call to employ psychological measurements in software engineering research. We report a study with 42 participants to investigate the relationship between the affective states, creativity, and analytical problem-solving skills of software developers. The results offer support for the claim that happy developers are indeed better problem solvers in terms of their analytical abilities. The following contributions are made by this study: (1) providing a better understanding of the impact of affective states on the creativity and analytical problem-solving capacities of developers, (2) introducing and validating psychological measurements, theories, and concepts of affective states, creativity, and analytical-problem-solving skills in empirical software engineering, and (3) raising the need for studying the human factors of software engineering by employing a multidisciplinary viewpoint.

    NASA has used aerobraking at Mars and Venus to reduce the fuel required to deliver a spacecraft into a desired orbit compared to an all-propulsive solution. Although aerobraking reduces the propellant, it does so at the expense of mission duration, large staff, and DSN coverage. These factors make aerobraking a significant cost element in the mission design. By moving on-board the current ground-based tasks of ephemeris determination, atmospheric density estimation, and maneuver sizing and execution, a flight project would realize significant cost savings. The NASA Engineering and Safety Center (NESC) sponsored Phase 1 and 2 of the Autonomous Aerobraking Development Software (AADS) study, which demonstrated the initial feasibility of moving these current ground-based functions to the spacecraft. This paper highlights key state-of-the-art advancements made in the Phase 2 effort to verify that the AADS algorithms are accurate, robust and ready to be considered for application on future missions that utilize aerobraking. The advancements discussed herein include both model updates and simulation and benchmark testing. Rigorous testing using observed flight atmospheres, operational environments and statistical analysis characterized the AADS operability in a perturbed environment.

    2011-01-01

    Full Text Available Nowadays, system developers are faced to produce complex, high quality software to support the demand for new and revised computer applications. This challenge is complicated by strict resource constraints, forcing management to deploy new technologies, methods and procedures to manage this increasingly complex environment. Often the methods, procedures and technologies are not integrated. Therefore, they achieve less than desired improvements in productivity, or force management to make tradeoff decisions between software quality and developer efficiency. Thus the production lines have to be developed faster, too. A very important role in this development is Software Engineering because many production processes are 'computer aided', so software has to be designed for this production system. It seems very important to do the software engineering right and fast.

    2015-01-01

    Academic software development practices often differ from those of commercial development settings, yet only limited research has been conducted on assessing software development practises in academia. Here we present a case study of software development practices in four open-source scientific codes over a period of nine years, characterizing the evolution of their respective development teams, their scientific productivity, and the adoption (or discontinuation) of specific software engineering practises as the team size changes. We show that the transient nature of the development team results in the adoption of different development strategies. We relate measures of publication output to accumulated numbers of developers and find that for the projects considered the time-scale for returns on expended development effort is approximately three years. We discuss the implications of our findings for evaluating the performance of research software development, and in general any computationally oriented scienti...

  3. Secure Software Configuration Management Processes for nuclear safety software development environment

    International Nuclear Information System (INIS)

    Highlights: → The proposed method emphasizes platform-independent security processes. → A hybrid process based on the nuclear SCM and security regulations is proposed. → Detailed descriptions and Process Flow Diagram are useful for software developers. - Abstract: The main difference between nuclear and generic software is that the risk factor is infinitely greater in nuclear software - if there is a malfunction in the safety system, it can result in significant economic loss, physical damage or threat to human life. However, secure software development environment have often been ignored in the nuclear industry. In response to the terrorist attacks on September 11, 2001, the US Nuclear Regulatory Commission (USNRC) revised the Regulatory Guide (RG 1.152-2006) 'Criteria for use of computers in safety systems of nuclear power plants' to provide specific security guidance throughout the software development life cycle. Software Configuration Management (SCM) is an essential discipline in the software development environment. SCM involves identifying configuration items, controlling changes to those items, and maintaining integrity and traceability of them. For securing the nuclear safety software, this paper proposes a Secure SCM Processes (S2CMP) which infuses regulatory security requirements into proposed SCM processes. Furthermore, a Process Flow Diagram (PFD) is adopted to describe S2CMP, which is intended to enhance the communication between regulators and developers.

    The Interactive Software Invocation System (ISIS), which allows a user to build, modify, control, and process a total flight software system without direct communications with the host computer, is described. This interactive data management system provides the user with a file manager, text editor, a tool invoker, and an Interactive Programming Language (IPL). The basic file design of ISIS is a five level hierarchical structure. The file manager controls this hierarchical file structure and permits the user to create, to save, to access, and to purge pages of information. The text editor is used to manipulate pages of text to be modified and the tool invoker allows the user to communicate with the host computer through a RUN file created by the user. The IPL is based on PASCAL and contains most of the statements found in a high-level programming language. In order to evaluate the effectiveness of the system as applied to a flight project, the collection of software components required to support the Annular Suspension and Pointing System (ASPS) flight project were integrated using ISIS. The ASPS software system and its integration into ISIS is described.

    We present an overview of a new VLBI analysis software under development at NASA GSFC. The new software will replace CALC/SOLVE and many related utility programs. It will have the capabilities of the current system as well as incorporate new models and data analysis techniques. In this paper we give a conceptual overview of the new software. We formulate the main goals of the software. The software should be flexible and modular to implement models and estimation techniques that currently exist or will appear in future. On the other hand it should be reliable and possess production quality for processing standard VLBI sessions. Also, it needs to be capable of processing observations from a fully deployed network of VLBI2010 stations in a reasonable time. We describe the software development process and outline the software architecture.

    Software effort estimation is a key element of software project planning and management. Yet, in industrial practice, the important role of effort estimation is often underestimated and/or misunderstood. In this book, Adam Trendowicz presents the CoBRA method (an abbreviation for Cost Estimation, Benchmarking, and Risk Assessment) for estimating the effort required to successfully complete a software development project, which uniquely combines human judgment and measurement data in order to systematically create a custom-specific effort estimation model. CoBRA goes far beyond simply predictin

  15. The Development of Software Pricing Schemata and Its Application to Software Industry in Korea

    2010-03-01

    Full Text Available The purpose of this this research is to suggest comprehensive pricing schemata that software developers can use in the integrated state of software uses. To do so, we have reviewed the pricing criteria that the current fields of business administration treat andoffered the basis of pricing systems. Then we have applied the prices of software products in Korea to the systems and earned abundant price payment units. As for the research works of software pricing at the present, however, it seems that they are mainly focused on the uses and functions of some specific software rather than on general variables that affect the software pricing policies of PC and Client/Server environment. There have been many researches on individual consumption features such as on the case of upgrade, on the case of outsourcing like ASP, on the case of pricing package items, or on the case of ERP software.[1-5] In other words, there have been few researches on the schemata of pricing that software developers can use. This paper aims to suggest a comprehensive pricing schemata that software developers, sellers, and distributers can use regardless of the state of software uses. To do so, first, itreviews the criteria of pricing that are frequently discussed in the current fields of economics and management and thereby establishes the basis that leads to a pricing schemata. Then the prices of software in Korea will be applied to the schemata, which will eventually make it possible to produce the complete pricing schemata unique in Korea.

    2008-01-01

    The Guidance and Control Software (GCS) project was the last in a series of software reliability studies conducted at Langley Research Center between 1977 and 1994. The technical results of the GCS project were recorded after the experiment was completed. Some of the support documentation produced as part of the experiment, however, is serving an unexpected role far beyond its original project context. Some of the software used as part of the GCS project was developed to conform to the RTCA/DO-178B software standard, "Software Considerations in Airborne Systems and Equipment Certification," used in the civil aviation industry. That standard requires extensive documentation throughout the software development life cycle, including plans, software requirements, design and source code, verification cases and results, and configuration management and quality control data. The project documentation that includes this information is open for public scrutiny without the legal or safety implications associated with comparable data from an avionics manufacturer. This public availability has afforded an opportunity to use the GCS project documents for DO-178B training. This report provides a brief overview of the GCS project, describes the 4-volume set of documents and the role they are playing in training, and includes the development documents from the GCS project. Volume 2 contains three appendices: A. Guidance and Control Software Development Specification; B. Design Description for the Pluto Implementation of the Guidance and Control Software; and C.

  6. Improve the Practice of Software Development by Having a Software Development Career Track in CS & IT Academia

    CERN Document Server

    Iyer, Ravi S

    2012-01-01

    Most CS & IT academics tend to have a focus on theory and research and do not give much importance to the practice of software development. This paper analyzes that the lack of career advancement incentive for CS & IT academics for mastering the practice of software development is the main reason for this rather odd situation. It proposes an additional software development career track for CS & IT academics different from the existing research oriented career track. A measure of software contribution record is suggested. It opines that adoption of such changes to academic regulations will result in significant improvement of software development skill set in CS & IT academia which, in turn, will result in better software development skill set in CS & IT graduates. While this paper uses the example of regulations of Indian CS & IT academia, similar academic regulations could be in use in other countries as well.

    Full Text Available Software Development is a core second-year course currently offered to undergraduate students atVictoria University at its five local and international campuses. The project aims to redesign the existingcourse curriculum to support student-centred teaching and learning. It is intended to provide a learningcontext in which learners can reflect on new material, discuss their tentative understandings with others,actively search for new information, develop skills in communication and collaboration, and buildconceptual connections to their existing knowledge base. The key feature of the cross-campus curriculuminnovation is the use of Blackboard, short for Blackboard Learning System, to assist in course contentorganization and online delivery. A well-defined and integrated case study is used throughout the courseto provide realistic practical experience of software development. It allows students to take control oftheir own learning while at the same time providing support to those students who have particularlearning difficulties. In this paper, the developed curriculum and the learning outcome are described. Thee-Learning material and various Blackboard tools used for teaching and learning activities arepresented. Finally, conclusion is drawn from classroom experience.

  12. Integrated software development for Wendelstein 7-X

    International Nuclear Information System (INIS)

    Steady-state fusion devices, such as Wendelstein 7-X, pose a new challenge to the software capabilities for control, data acquisition and data analysis. These modules must cope with huge amounts of data. Proof-of-principle demonstrations of important steps in a physically motivated framework are shown to be feasible. This includes integrated data analysis from different diagnostics and coupling of modeling codes, even for advanced device control. The present approach makes use of a strict modular design and already allows the use of modules in present design and optimization studies of device components and diagnostics setups. A striking benefit is provided by embedding validated legacy codes within a service oriented software architecture, thereby ameliorating incompatibility issues. (author)

    Section 508 Subpart B 1194.21 outlines requirements for operating system and software development in order to create a product that is accessible to users with various disabilities. This portion of Section 508 contains a variety of standards to enable those using assistive technology and with visual, hearing, cognitive and motor difficulties to access all information provided in software. The focus on requirements was limited to the Microsoft Windows® operating system as it is the predominant operating system used at this center. Compliance with this portion of the requirements can be obtained by integrating the requirements into the software development cycle early and by remediating issues in legacy software if possible. There are certain circumstances with software that may arise necessitating an exemption from these requirements, such as design or engineering software using dynamically changing graphics or numbers to convey information. These exceptions can be discussed with the Section 508 Coordinator and another method of accommodation used.

Multiple Instruction stream Multiple Data stream (MIMD) computers have been developed to overcome the performance limitations of serial computers. The hardware architectures of MIMD computers vary considerably and are much more sophisticated than serial computers. Developing large scale software for a variety of MIMD computers is difficult and expensive. There is a need to provide tools that facilitate programming these machines. First, the issues that must be considered to develop those tools are examined. The two main areas of concern were architecture independence and data management. Architecture independent software facilitates software portability and improves the longevity and utility of the software product. It provides some form of insurance for the investment of time and effort that goes into developing the software. The management of data is a crucial aspect of solving large engineering problems. It must be considered in light of the new hardware organizations that are available. Second, the functional design and implementation of a software environment that facilitates developing architecture independent software for large engineering applications are described. The topics of discussion include: a description of the model that supports the development of architecture independent software; identifying and exploiting concurrency within the application program; data coherence; engineering data base and memory management.

    Systems type UAV / UAS enable acquisition of huge amounts of data, such as images. For their storage and analysis IT systems are necessary. Existing systems do not always allow you to perform such operations as researchers wish to [1]. The purpose of the research is to automate the process of recognizing objects and phenomena occurring on grasslands. The basis for action are numerous collections of images taken from the oktokopter [2]. For the purpose of the collection, management and analysis of image data and character acquired in the course of research, in accordance with the principles of software engineering several computer programs has been produced. The resulting software is different functionality and type. Applications were made using a number of popular technologies. The choice of so many technology was primarily dictated by the possibilities of their use for specific tasks and availability on different platforms and the ability to distribute open source. Applications presented by the authors, designed to assess the status of grassland based on aerial photography, show the complexity of the issues but at the same time tend to further research.

  3. Improving the Software Development Process Using Testability Research

    Science.gov (United States)

    Voas, Jeffrey M.; Miller, Keith W.

    1991-01-01

    Software testability is the the tendency of code to reveal existing faults during random testing. This paper proposes to take software testability predictions into account throughout the development process. These predictions can be made from formal specifications, design documents, and the code itself. The insight provided by software testability is valuable during design, coding, testing, and quality assurance. We further believe that software testability analysis can play a crucial role in quantifying the likelihood that faults are not hiding after testing does not result in any failures for the current version.

  7. Elimination of Estimation biases in the Software Development

    Directory of Open Access Journals (Sweden)

    Thamarai . I.

    2015-04-01

    Full Text Available The software effort estimations are usually too low and the prediction is also a very difficult task as software is intangible in nature. Also the estimation is based on the parameters that are usually partial in nature. It is an important management activity. Despite much research in this area, the accuracy of effort estimation is very low. This results in poor project planning and failure of many software projects. One of the reasons for this poor estimation is that the estimation given by the software developers are affected by some information which do not have any relevance to the calculation of effort. To avoid this, we have proposed a new methodology in which we analyze the relationship between the estimation bias and the various features of developers such as the role in the company, thinking style, experience, education, software development skills, etc. It is found that the estimation bias increases with higher levels of interdependence.

    This work is a two-volume set on standards for modern software engineering methodology. This volume presents a tutorial and practical guide to the efficient development of reliable computer software, a unified and coordinated discipline for design, coding, testing, documentation, and project organization and management. The aim of the monograph is to provide formal disciplines for increasing the probability of securing software that is characterized by high degrees of initial correctness, readability, and maintainability, and to promote practices which aid in the consistent and orderly development of a total software system within schedule and budgetary constraints. These disciplines are set forth as a set of rules to be applied during software development to drastically reduce the time traditionally spent in debugging, to increase documentation quality, to foster understandability among those who must come in contact with it, and to facilitate operations and alterations of the program as requirements on the program environment change.

    2008-01-01

    COCOMOST is a computer program for use in estimating software development costs. The goal in the development of COCOMOST was to increase estimation accuracy in three ways: (1) develop a set of sensitivity software tools that return not only estimates of costs but also the estimation error; (2) using the sensitivity software tools, precisely define the quantities of data needed to adequately tune cost estimation models; and (3) build a repository of software-cost-estimation information that NASA managers can retrieve to improve the estimates of costs of developing software for their project. COCOMOST implements a methodology, called '2cee', in which a unique combination of well-known pre-existing data-mining and software-development- effort-estimation techniques are used to increase the accuracy of estimates. COCOMOST utilizes multiple models to analyze historical data pertaining to software-development projects and performs an exhaustive data-mining search over the space of model parameters to improve the performances of effort-estimation models. Thus, it is possible to both calibrate and generate estimates at the same time. COCOMOST is written in the C language for execution in the UNIX operating system.

  16. Pragmatic quality metrics for evolutionary software development models

    Science.gov (United States)

    Royce, Walker

    1990-01-01

    Due to the large number of product, project, and people parameters which impact large custom software development efforts, measurement of software product quality is a complex undertaking. Furthermore, the absolute perspective from which quality is measured (customer satisfaction) is intangible. While we probably can't say what the absolute quality of a software product is, we can determine the relative quality, the adequacy of this quality with respect to pragmatic considerations, and identify good and bad trends during development. While no two software engineers will ever agree on an optimum definition of software quality, they will agree that the most important perspective of software quality is its ease of change. We can call this flexibility, adaptability, or some other vague term, but the critical characteristic of software is that it is soft. The easier the product is to modify, the easier it is to achieve any other software quality perspective. This paper presents objective quality metrics derived from consistent lifecycle perspectives of rework which, when used in concert with an evolutionary development approach, can provide useful insight to produce better quality per unit cost/schedule or to achieve adequate quality more efficiently. The usefulness of these metrics is evaluated by applying them to a large, real world, Ada project.

  18. Ideas for a Cooperative Software Development for Future GGOS Stations

    Science.gov (United States)

    Neidhardt, A.; Ettl, M.

    2012-12-01

    The development of software is a creative process, which offers a huge degree of freedom. In scientific fields a lot of researchers develop their own software for specific needs. Everyone has their own preferences and backgrounds regarding the used programming languages, styles, and platforms. This complexity results in software which is not always directly usable by others in the communities. In addition, the software is often error-prone as hidden bugs are not always revealed. Therefore ideas came up to solve these problems at the Geodetic Observatory Wettzell. The results were coding layouts and policies, documentation strategies, the usage of version control, and a consistent process of continuous integration. Within this, the discussed quality factors can define quality metrics which help to quantize code quality. The resulting software is a repository of tested modules that can be used in different programs for the geodetic space techniques. This is one possible contribution to future GGOS stations.

    2006-01-01

    Setting up the infrastructure to manage a software project can become a task as significant writing the software itself. A variety of useful open source tools are available, such as Web-based viewers for version control systems, "wikis" for collaborative discussions and bug-tracking systems, but their use in high-energy physics, outside large collaborations, is insubstantial. Understandably, physicists would rather do physics than configure project management tools. We introduce the CEDAR HepForge system, which provides a lightweight development environment for HEP software. Services available as part of HepForge include the above-mentioned tools as well as mailing lists, shell accounts, archiving of releases and low-maintenance Web space. HepForge also exists to promote best-practice software development methods and to provide a central repository for re-usable HEP software and phenomenology codes.

    1991-01-01

    The cost of developing computer software continues to consume an increasing portion of many organizations' total budgets, both in the public and private sector. As this trend develops, the capability to produce reliable estimates of the effort and schedule required to develop a candidate software product takes on increasing importance. The COSTMODL program was developed to provide an in-house capability to perform development cost estimates for NASA software projects. COSTMODL is an automated software development cost estimation tool which incorporates five cost estimation algorithms including the latest models for the Ada language and incrementally developed products. The principal characteristic which sets COSTMODL apart from other software cost estimation programs is its capacity to be completely customized to a particular environment. The estimation equations can be recalibrated to reflect the programmer productivity characteristics demonstrated by the user's organization, and the set of significant factors which effect software development costs can be customized to reflect any unique properties of the user's development environment. Careful use of a capability such as COSTMODL can significantly reduce the risk of cost overruns and failed projects.

  19. Development of advanced seismic PSA software, PRASSE

    International Nuclear Information System (INIS)

    In this study, a computer program, PRASSE (Probabilistic Risk Assessment of Systems for Seismic Events), was developed for calculating an initiating event frequency. The developed program has some useful features. For easy use and reducing input errors, PRASSE was developed based on a GUI. In the GUI system, an accident sequence is modeled using Event Trees (ETs) and Fault Trees (FTs). Boolean expressions are automatically generated from the ET/FT editor by a Binary Decision Decision Diagram (BDD) method to represent the exact results of prime implicants. For estimating the plant level fragility, a sampling based uncertainty analysis was introduced. In this matter, either the Monte Carlo Simulation or Latin Hypercube Sampling method can be selected in this code. To consider failure probabilities induced by a correlation of response and capacity under an earthquake vibration, the seismic correlation module was developed based on the methodology in the SSMRP study. The power value of the seismic correlation coefficient was suggested by the simplified equation for calculation efficiency. The failure probability of random failure components such as a human operation error is modeled as the variable dependent on the seismic intensity. (author)

    In the medical diagnosis, the nuclear medical instrument using the radioactive isotope are commonly utilized. In the foreign countries, the medical application and development of the most advanced nuclear medical instrument such as Single Photon Emission Computer Tomography (SPECT) and position emission tomograph (PET), have been extensively carried out. However, in Korea, such highly expensive instruments have been all, imported, paying foreign currency. Since 1997, much efforts, the development of the radio nuclide medical instrument, the drive of the domestic production, etc. have been made to establish our own technologies and to balance the international payments under the support of the Ministry of Science and Technology. At present time, 180 nuclear imaging instruments are now in operation and 60 of them are analog camera. In analog camera, the vector X-Y monitor is need for are image display. Since the analog camera, signal can not be process in the digital form, we have difficulties to transfer and store the image data. The image displayed at the monitor must be stored in the form of polaroid or X ray film. In order to discard these disadvantages, if we developed the computer interface system, the performance analog camera will be comparable with that of the digital camera. The final objective of the research is that using the interface system developed in this research, we reconstruct the image data transmitted to the personal computer in the form of the generalized data file.

    2015-06-01

    Full Text Available A novel methodology, result of 10 years of in-field testing, which makes possible the convergence of different types of models and quality standards for Engineering and Computer Science Faculties, is presented. Since most software-developing companies are small and medium sized, the projects developed must focuson SCRUM and Extreme Programming (XP, opposed to a RUP, which is quite heavy, as well as on Personal Software Process (PSP and Team Software Process (TSP, which provide students with competences and a structured framework. ISO 90003:2004 norm is employed to define the processes by means of a quality system without new requirements or changing the existing ones. Also, the model is based on ISO/IEC 25000 (ISO (IEC 9126 – ISO/IEC 14598 to allow comparing software built by different metrics.

  4. Formal methods in software development: A road less travelled

    Directory of Open Access Journals (Sweden)

    John A van der Poll

    2010-08-01

    Full Text Available An integration of traditional verification techniques and formal specifications in software engineering is presented. Advocates of such techniques claim that mathematical formalisms allow them to produce quality, verifiably correct, or at least highly dependable software and that the testing and maintenance phases are shortened. Critics on the other hand maintain that software formalisms are hard to master, tedious to use and not well suited for the fast turnaround times demanded by industry. In this paper some popular formalisms and the advantages of using these during the early phases of the software development life cycle are presented. Employing the Floyd-Hoare verification principles during the formal specification phase facilitates reasoning about the properties of a specification. Some observations that may help to alleviate the formal-methods controversy are established and a number of formal methods successes is presented. Possible conditions for an increased acceptance of formalisms in oftware development are discussed.

    2006-01-01

    Specialized software systems have played a crucial role throughout the twenty-five year course of the development of the new technology of imaging spectroscopy, or hyperspectral remote sensing. By their very nature, hyperspectral data place unique and demanding requirements on the computer software used to visualize, analyze, process and interpret them. Often described as a marriage of the two technologies of reflectance spectroscopy and airborne/spaceborne remote sensing, imaging spectroscopy, in fact, produces data sets with unique qualities, unlike previous remote sensing or spectrometer data. Because of these unique spatial and spectral properties hyperspectral data are not readily processed or exploited with legacy software systems inherited from either of the two parent fields of study. This paper provides brief reviews of seven important software systems developed specifically for imaging spectroscopy.

    Bendeck, Fawsy; Goldmann, Sigrid; Holz, Harald; Kötting, Boris

    1999-01-01

    Coordinating distributed processes, especially engineering and software design processes, has been a research topic for some time now. Several approaches have been published that aim at coordinating large projects in general, and large software development processes in specific. However, most of these approaches focus on the technical part of the design process and omit management activities like planning and scheduling the project, or monitoring it during execution. In this paper, we focus o...

    Full Text Available Background: Knowledge-creation is a field of study that has gained popularity in recent times.Knowledge-creation is the creation of new ideas or new innovations. In computing, software development is regarded as knowledge-creation. This is because software-development involves the creation of a new innovation (software. Knowledge-creation studies in this field tend to focus mainly on knowledge-creation activities in business organisations. They use experienced, professional software-development teams as subjects, largely ignoring novice student development teams. This has denied the field of computing valuable knowledge about how novice teams create knowledge.Objectives: The study addressed this gap in the literature by investigating knowledge-creation in student software teams.Method: An ethnographic study was conducted on six student teams developing software in a management-information systems (MIS course. They were conducting a systems development project at a university during a term of study. Data were collected over a period of four months through participant observation and interviews.Results: The results reveal knowledge-creation activities such as problem definition,brainstorming, programming and system documentation. Students use the Internet, books,class notes, class presentations, senior students and professional software developers as sources of information. Mobile phones and BlackBerry devices facilitate knowledge-creation.Challenges to knowledge-creation are the lack of material and financial resources,a lack of technical skills, a lack of time, students staying off-campus and ambivalent team members.Conclusion: The conclusion drawn from this study is that student teams are capable of creating knowledge (a working system just like professional teams, but the knowledge-creation process is slightly different.

  4. Development of NMCA system and software

    International Nuclear Information System (INIS)

    Full text: Development of the NMCA system in the Institute of Atomic Energy is described. The Institute is the one of research scientific subdivisions of the National Nuclear Center of the Republic of Kazakhstan. Four nuclear facilities in the country is operating. Institute is a facility with two research reactors, located on the remote sites of the former Semipalatinsk nuclear test site. Layouts and main parameters of the reactors are attached. In additional to reactors, NM storages, on-pile stands, research labs and hot cell are located on sites. The NM storing and handling are covered by NMCA system which after USSR disintegration was in a bad condition: on-paper account, lack of personal training, normative documents, measuring system, and access control. After ratification of Safeguards Agreement all Kazakhstan's nuclear facilities became to being inspected by IAEA and State authority. Putting of the NMCA system according to international rules is started. Since 1993 a collaboration with Departments of Defense and Energy is begun, particularly with Los-Alamos, Sandia and Oak-Ridge National labs. Directions of development and needs of technical and methodical assistance were defined. In the following time a computers for account, spectrometric and weighing equipment for NDA, TID and other office equipment were delivered. Development of a number of documents concerning regulation of NM handling, IAEA inspectors cooperation, reporting was conducted under ORNL support. NMCA custodians were participants of many training courses held in Kazakhstan, NIS, LANL, NRC. The computerized NMCA system 'AIMAS' developed in ANL and delivered to the Institute was implemented successfully in 1995. During some followed years the 'AIMAS' system was modified step by step and spread to other nuclear facilities of Kazakhstan and Uzbekistan under DOE support. The important element of supporting of SSAC development in Kazakhstan is funding and providing with methodic of annual

  5. Need for multiple approaches in collaborative software development

    International Nuclear Information System (INIS)

    The need to share software and reintegrate it into new applications presents a difficult but important challenge. Component-based development as an approach to this problem is receiving much attention in professional journals and academic curricula. However, there are many other approaches to collaborative software development that might be more appropriate. This paper reviews a few of these approaches and discusses criteria for the conditions and contexts in which these alternative approaches might be more appropriate. This paper complements the discussion of context-based development team organizations and processes. Examples from a small development team that interacts with a larger professional community are analyzed

    National Aeronautics and Space Administration (NASA) has developed an on-orbit, adaptable, Software Defined Radio (SDR)Space Telecommunications Radio System (STRS)-based testbed facility to conduct a suite of experiments to advance technologies, reduce risk, and enable future mission capabilities on the International Space Station (ISS). The SCAN Testbed Project will provide NASA, industry, other Government agencies, and academic partners the opportunity to develop and field communications, navigation, and networking technologies in the laboratory and space environment based on reconfigurable, SDR platforms and the STRS Architecture.The SDRs are a new technology for NASA, and the support infrastructure they require is different from legacy, fixed function radios. SDRs offer the ability to reconfigure on-orbit communications by changing software for new waveforms and operating systems to enable new capabilities or fix any anomalies, which was not a previous option. They are not stand alone devices, but required a new approach to effectively control them and flow data. This requires extensive software to be developed to utilize the full potential of these reconfigurable platforms. The paper focuses on development, integration and testing as related to the avionics processor system, and the software required to command, control, monitor, and interact with the SDRs, as well as the other communication payload elements. An extensive effort was required to develop the flight software and meet the NASA requirements for software quality and safety. The flight avionics must be radiation tolerant, and these processors have limited capability in comparison to terrestrial counterparts. A big challenge was that there are three SDRs onboard, and interfacing with multiple SDRs simultaneously complicatesd the effort. The effort also includes ground software, which is a key element for both the command of the payload, and displaying data created by the payload. The verification of

    Ocean information management is of great importance as it has been employed in many areas of ocean science and technology. However, the developments of Ocean Information Systems (OISs) often suffer from low efficiency because of repetitive work and continuous modifications caused by dynamic requirements. In this paper, the basic requirements of OISs are analyzed first, and then a novel platform DPOI is proposed to improve development efficiency and enhance software quality of OISs by providing off-the-shelf resources. In the platform, the OIS is decomposed hierarchically into a set of modules, which can be reused in different system developments. These modules include the acquisition middleware and data loader that collect data from instruments and files respectively, the database that stores data consistently, the components that support fast application generation, the web services that make the data from distributed sources syntactical by use of predefined schemas and the configuration toolkit that enables software customization. With the assistance of the development platform, the software development needs no programming and the development procedure is thus accelerated greatly. We have applied the development platform in practical developments and evaluated its efficiency in several development practices and different development approaches. The results show that DPOI significantly improves development efficiency and software quality.

    2016-03-01

    Jefferson Lab (Jlab) is performing a large-scale upgrade to their Continuous Electron Beam Accelerator Facility (CEBAF) up to 12GeV beam. The Large Acceptance Spectrometer (CLAS12) in Hall B is being upgraded and a new Ring Imaging Cherenkov (RICH) detector is being developed to provide better kaon - pion separation throughout the 3 to 12 GeV range. With this addition, when the electron beam hits the target, the resulting pions, kaons, and other particles will pass through a wall of translucent aerogel tiles and create Cherenkov radiation. This light can then be accurately detected by a large array of Multi-Anode PhotoMultiplier Tubes (MA-PMT). I am presenting an update on my work on the implementation of Java based reconstruction programs for the RICH in the CLAS12 main analysis package.

    The report documents the task planning and software development phases of an effort to obtain twenty versions of code independently designed and developed from a common specification. These versions were created for use in future experiments in software fault tolerance, in continuation of the experimental series underway at the Systems Validation Methods Branch (SVMB) at NASA Langley Research Center. The 20 versions were developed under controlled conditions at four U.S. universities, by 20 teams of two researchers each. The versions process raw data from a modified Redundant Strapped Down Inertial Measurement Unit (RSDIMU). The specifications, and over 200 questions submitted by the developers concerning the specifications, are included as appendices to this report. Design documents, and design and code walkthrough reports for each version, were also obtained in this task for use in future studies.

  12. Decision aid software development for nuclear reactors

    International Nuclear Information System (INIS)

    The development of new techniques, especially in the field of Artificial Intelligence, makes it possible to design more powerful computerised systems supporting tasks related to the design and operation of nuclear power plants. The potential contribution and perspectives for the integration of such systems depend upon whether the improvement of existing plants, the design of next generation reactors or future projects are concerned. This paper will present four systems which show the state of the art in the field of knowledge-based systems. The first one is related to the automatic generation of accidental procedures dealing with the loss of electrical power supply. The second one aims at assisting the power plant utility in following the technical specifications during maintenance operations. Finally, the last two are designed to help an emergency team to evaluate and to forecast the evaluation of an accidental situation in a nuclear reactor plant. Perspectives for one-line operator assistance are then discussed, as well as the main technical topics which will make possible the design of such systems. We conclude with the difficulties which are encountered upon integration of these tools: their validation and the task sharing between man and machine. (author). 8 refs

  13. Epistemic Communities, Situated Learning and Open Source Software Development

    2001-01-01

    This paper analyses open source software (OSS) development as an epistemic community where each individual project is perceived as a single epistemic community. OSS development is a learning process where the involved parties contribute to, and learn from the community. It is discovered that theory...... of epistemic communities does indeed contribute to the understanding of open source software development. But, the important learning process of open source software development is not readily explained. The paper then introduces situated learning and legitimate peripheral participation as...... theoretical perspectives. This allows the learning process to be part of the activities in the epistemic community. The combination of situated learning and epistemic communities is shown to be fruitful and capable of explaining some of the empirical observations. In particular the combination of theories can...

    Full Text Available Risk approaches in project development led to the integration in the IT project management methodologies and software development of activities and processes of risk management. The diversity and the advanced level of the used technologies in IT projects with increasing com-plexity leads to an exponential diversification of risk factors.The purpose of this research is to identify the level of the risk approach in IT projects both at the IT project management and software development methodologies level and the level of the perception of IT project man-agers, IT managers and IT analysts in Romanian IT companies. Thus, we want to determine the correlation between the use of a project management or software development methodology and the overall level of risk perceived by the project managers using these methodologies.

    Application of computer technology in nuclear power plant is also a necessary transformation as in other industry fields. But until now, application of software technology was not wide-spread because of its potential effect to safety in nuclear field. It is an urgent theme to develop evaluation guide and regulation techniques to guarantee safety, reliability and quality assurance. To meet these changes, techniques for development and operation should be enhanced to ensure the quality of software systems. In this study, we show the difference between waterfall model and software life-cycle needed in development of nuclear power plant and propose the consistent framework needed in development of instrumentation and control system of nuclear power plant.

  19. Software development for Indus-1 bunch filling pattern measurement

    International Nuclear Information System (INIS)

    Indus-1 is a 450 MeV synchrotron radiation source operational at RRCAT Indore. In Indus-1 storage ring, electrons are stored in two bunches. The distribution of beam current in these two bunches is termed as bunch filling pattern. In Indus-1, it is desirable to have symmetric bunch filling pattern for its optimum performance. This paper describes the development of software for bunch filling pattern measurement of Indus-1. This software measures the current distribution of the electron bunches circulating in the storage ring. To measure bunch currents wall current monitor (WCM) installed in the Indus-1 storage ring is used. Using a 500 MHz digital storage oscilloscope as a high-speed digitizer and online data processing by the developed software, measurement of online bunch filling pattern was achieved. This software has helped Indus operation crew to achieve desired bunch current symmetry in the Indus-1 storage ring. The software has the provision to store the online bunch current symmetry into a Microsoft-excel file which can be used for further analysis. Using this software, up to 99% bunch filling symmetry has been achieved by Indus operation crew. (author)

  20. EPICS: A control system software co-development success story

    International Nuclear Information System (INIS)

    The Experimental Physics and Industrial Control Systems (EPICS) is the result of a software sharing and co-development effort of major importance now underway. The initial two participants, LANL and ANL, have now been joined by three other labs, and an earlier version of the software has been transferred to three commercial firms and is currently undergoing separate development. The reasons for EPICS's success may be useful to enumerate and explain and the desire and prospects for its continued development are certainly worth examining
