Development of a Model Architecture for Job Scheduling

Job scheduling has a long history. Job schedulers have been one of the major component of IT infrastructure since the early mainframe system, at first, stacks of punched cards were processed one after the other, hence the term batch processing. The aim of a job scheduler was to arrange, control and optimize work and workload in a production process. The study aimed at achieving a job scheduler that can assign jobs to available resources in such a way that workload leveling can be achieved. The objectives of the study included to; ascertain the existing schedule system, design a model platform for job scheduling, implement the model platform for job scheduling, and test and deploy the model platform for job scheduling. The study adopted the spiral development model. The proposed system was developed using java script which is a client scripting language which is used for creating web and windows application and it has almost all online application since the system is an online system. The developed application was tested with field Meta data and the outcome was according to specification and of desired output. The application was hosted on three different servers, one server for the frontend, another server for the backend and the third server for the database, hosting on the three different servers did the magic by making the system faster and easy to optimize.

Bioethics in the Future: Ecological Upbringing from a Preschool Age. A Drama Music Workshop as an Example

Abstract In today’s society, public opinion plays a large role in the adoption of various legal measures and regulations, including those related to the field of bioethics. This is why experts have a duty to inform the public in a timely and accurate manner, and it is up to educators to educate new generations to become responsible citizens who can make informed decisions. A few years ago, attempts were made to implement a project of health education and then one of civic education in schools. Those curricula predict the student will develop human, political, social, cultural, economic and environmental competences as a citizen of the class, school and local community. A spiral development model of introduction by educational cycles is envisaged, starting from the 1st grade of primary school. However, civic education is also addressed by the national curriculum for early and preschool education, which anticipates development of social and civic competences in children of this age. Bioethics and environmental issues are still not sufficiently transparent to the public. This is why proper environmental education from preschool age is very important. In preschool education, the proper approach is essential, and contemporary pedagogy emphasizes the importance of learning through play. The artistic fields are imposed as an ideal framework in which various contents can be accommodated. A drama music workshop that will help children develop awareness of various issues through play is, therefore, an ideal training ground for educating a responsible and informed citizen. One such drama music workshop was organized for the purpose of demonstration on the occasion of the First Osijek Days of Bioethics. The story used in the workshop is from a picture book by Aleix Cabrera and Rosa M. Curto: Niko and nutrition. Through the play and the story, the importance of proper nutrition was emphasized to children and made them aware that it is necessary to know what they actually eat and where and how food comes from. This paper uses the workshop as a starting point when discussing the role of artistic fields and educators in creating a responsible and informed citizen in fields of bioethics and environmental issues and the importance of early and preschool education in the process.

A Spiral Development Model for an Advanced Traffic Management System (ATMS) Architecture Based on Prototype

As a symbol of economic growth, the deployment of an Intelligent Transportation System (ITS) became a necessity of a country, especially in a developing country. The Advanced Transportation Management System (ATMS) is one of the pivotal subsystems of ITS. With the development of digital image processing, the deployment of such a system can be implemented in an effective and economical way. The process of constructing an ATMS with minimum cost and time will be an important criterion in the selection of such a system for a developing country. In this paper, a spiral development method for an ATMS based on prototype was presented in order to overcome the shortcomings of the traditional waterfall model. The focus on the spiral development is to improve the design concepts and system requirements to avoid large-scale modification in the later development phases due to errors caused in the early ones. An applied architecture is constituted with the innovative technologies, e.g. 4th-generation mobile technology (4G), high-speed optical fiber communication technology with a national traffic communication backbone network in China, which ensures the latest technology is available to traffic management.

Guanxi and trust in strategic alliances

PurposeThe purpose of this paper is to distinguish different types of guanxi from a historic perspective and to investigate the effects of different types of guanxi on trust between alliance partners through an empirical study.Design/methodology/approachThe paper first reviews the role of guanxi in Chinese history and identifies two types of guanxi. Next, it reports an empirical study that tests the effects of these two types of guanxi on interorganizational trust through a survey among automobile parts suppliers in China.FindingsFirst, this paper identifies two types of guanxi: role‐based hierarchical guanxi endorsed by Confucianism and soil‐rooted egocentric guanxi derived from daily practices of Chinese people. The ever changing social environment in Chinese history supports a spiral development model of guanxi evolution. Each of the two types of guanxi takes a dominant position in different periods of time. Second, a subsequent empirical study demonstrates that, in today's Chinese business environment, role‐based guanxi makes a more significant impact on interorganizational trust than soil‐rooted guanxi. Moreover, these two types of guanxi produce a positive synergistic effect and facilitate each other in boosting interorganizational trust.Originality/valueThis is the first paper that identifies and empirically tests the effects of role‐based hierarchical guanxi and soil‐rooted egocentric guanxi. More broadly, the paper highlights the importance of studying guanxi from a historic perspective. It demonstrates how a historical analysis may further the understanding of guanxi and its effect on interorganizational trust in today's business context.

Security considerations for the spiral development model

Security measures have been well established within the waterfall development life cycle model. However, more software projects are using the spiral development life cycle model. Software developers and project managers can easily forget about adapting security measures. The spiral model uses iterative steps that can create changes in each phase of software development process. This will challenge security to ensure the application has few flaws or vulnerabilities that could be exploited. Failure to impose the right security measures at each of these phases can open up vulnerabilities for hackers to exploit and prove costly in patching. This paper will explore areas where security can be engaged within each iteration step of the spiral development model. This way security can continue protection of the software product as it becomes ready for deployment. The paper will help organizations realize where to deploy security measures to reduce vulnerabilities in the software application.

Design Analysis of Autonomous Air Traffic Flight Control System

Software architectural design, also known as top-level design, describes the software top-level structure and organization and identifies the various components. The concept of an automated air traffic flight control system which controls airplanes requires a high degree of operational integrity and availability. One possible solution to alleviate air travel congestion could be the automation of air traffic control and allowing it to have direct control over airplane flight paths. Such a system would, in theory, reduce the workload of the flight crew and the air traffic controllers, as well as increase traffic flow. This paper presents several analyses of such a conceptual system from a net-centric perspective. First, the systems operation is described from the context of a flight, to provide a basis for the discussion of various system models and views. Spiral development model stages as well as related events which occur during system design give an idea of how the system would be developed incrementally. Formal methods can be used to improve software security but can be costly and also have limitations of scale, training, and applicability. To compensate for the limitations of scale, formal methods can be applied to selected parts or properties of a software project, in contrast to applying them to the entire system. The concept of object-oriented development (OOD) has gradually matured from being presented. The OOD can still be regarded as one of the mainstream development models. UML includes a standardized graphical notation used to create an abstract model of a system, referred to as a UML model. We describe AATFCS system with UML modeling techniques. AADL is an extensible and allows us to introduce new properties; we can define a set of properties specific to the data state variable. In this paper we present the AADL language for AATFCS system.

Spiral evolution applied to legacy avionics systems

The US Department of Defense (DoD), through the Office of the Secretary of Defense (OSD), has determined that evolutionary acquisition is their strategy of choice for future software-intensive systems, and that the spiral development model (SDM) is the preferred method/process for software-intensive development life cycles. Electronic Systems Command (ESC) at Hanscom AFB, Massachusetts, has written a draft handbook on the use of Spiral Development for all future Command and Control (C2) systems, including reference to the DoD 5000 series and Air Force Program Directive 63-1, Acquisition System, which deploys this OSD mandate for future C2 systems. Barry Boehm's continued work on SDM which he conceived in the 1980s, is heavily biased toward development of new systems that are software-intensive, as noted in a workshop he gave at the Software Engineering Institute (SEI) in 2000.
