Incorporating object analysis and design into a structured information systems development life cycle

An object approach to information system development should be incorporated into the structured system design life cycle (SDLC) during the analysis and design phases. The tools of the structured approach (data flow diagrams, data structures, data stores, etc.) help to identify the relationships that exist between the data stores and the entities (objects) within an information system. This is only a starting point at which the IS developer further evaluates me informational needs that are required within the information system. A listing of the data structures is generated to assodate the specific data elements that comprise each data structure. A series of logical steps (normalization) can be used to remove the redundancy and inflexibility within each data structure. The end result of the nonhalization process is the generation of an entity-relationship diagram (E-R diagram). The E-R diagram can be used as a reference point in which to apply a series of objed oriented analysis and design steps to insure that information coUeded on objeds throughout the organization is properly integrated into the SDLC. A revised diagram is subsequently used to modify the data flow diagrams which will be the basis for the design of the new system. Thus, the objed approach to information system development is an integral component of the structured system design life cyde

Developing computational thinking in the classroom: a framework

Computational thinking sits at the heart of the new statutory programme of study for Computing: “A high quality computing education equips pupils to use computational thinking and creativity to understand and change the world” (Department for Education, 2013, p. 188). This document aims to support teachers to teach computational thinking. It describes a framework that helps explain what computational thinking is, describes pedagogic approaches for teaching it and gives ways to assess it. Pupil progression with the previous ICT curriculum was often demonstrated through ‘how’ (for example, a software usage skill) or ‘what’ the pupil produced (for example, a poster). This was partly due to the needs of the business world for office skills. Such use of precious curriculum time however has several weaknesses. Firstly, the country’s economy depends on technological innovation not just on use of technology. Secondly, the pace of technology and organisational change is fast in that the ICT skills learnt are out of date before a pupil leaves school. Thirdly, technology invades all aspects of our life and the typically taught office practice is only a small part of technology use today

The Partial Evaluation Approach to Information Personalization

Information personalization refers to the automatic adjustment of information content, structure, and presentation tailored to an individual user. By reducing information overload and customizing information access, personalization systems have emerged as an important segment of the Internet economy. This paper presents a systematic modeling methodology - PIPE (`Personalization is Partial Evaluation') - for personalization. Personalization systems are designed and implemented in PIPE by modeling an information-seeking interaction in a programmatic representation. The representation supports the description of information-seeking activities as partial information and their subsequent realization by partial evaluation, a technique for specializing programs. We describe the modeling methodology at a conceptual level and outline representational choices. We present two application case studies that use PIPE for personalizing web sites and describe how PIPE suggests a novel evaluation criterion for information system designs. Finally, we mention several fundamental implications of adopting the PIPE model for personalization and when it is (and is not) applicable.Comment: Comprehensive overview of the PIPE model for personalizatio

Adaptive Automation Design and Implementation

Automations allow us to reduce the need for humans in certain environments, such as auto-pilot features on unmanned aerial vehicles. However, some situations still require human intervention. Adaptive automation is a research field that enables computer systems to adjust the amount of automation by taking over tasks from or giving tasks back to the user. This research develops processes and insights for adaptive automation designers to take theoretical adaptive automation ideas and develop them into real-world adaptive automation system. These allow developers to design better automation systems that recognize the limits of computers systems, enabling better designs for systems in fields such as multi-aircraft control. This research was sponsored by AFOSR

A Human Factors Framework for Payload Display Design

During missions to space, one charge of the astronaut crew is to conduct research experiments. These experiments, referred to as payloads, typically are controlled by computers. Crewmembers interact with payload computers by using visual interfaces or displays. To enhance the safety, productivity, and efficiency of crewmember interaction with payload displays, particular attention must be paid to the usability of these displays. Enhancing display usability requires adoption of a design process that incorporates human factors engineering principles at each stage. This paper presents a proposed framework for incorporating human factors engineering principles into the payload display design process

Commercialization of Medium Voltage HTS Triax TM Cable Systems

The original project scope that was established in 2007 aimed to install a 1,700 meter (1.1 mile) medium voltage HTS Triax{TM} cable system into the utility grid in New Orleans, LA. In 2010, however, the utility partner withdrew from the project, so the 1,700 meter cable installation was cancelled and the scope of work was reduced. The work then concentrated on the specific barriers to commercialization of HTS cable technology. The modified scope included long-length HTS cable design and testing, high voltage factory test development, optimized cooling system development, and HTS cable life-cycle analysis. In 2012, Southwire again analyzed the market for HTS cables and deemed the near term market acceptance to be low. The scope of work was further reduced to the completion of tasks already started and to testing of the existing HTS cable system in Columbus, OH. The work completed under the project included: • Long-length cable modeling and analysis • HTS wire evaluation and testing • Cable testing for AC losses • Optimized cooling system design • Life cycle testing of the HTS cable in Columbus, OH • Project management. The 200 meter long HTS Triax{TM} cable in Columbus, OH was incorporated into the project under the initial scope changes as a test bed for life cycle testing as well as the site for an optimized HTS cable cooling system. The Columbus cable utilizes the HTS TriaxTM design, so it provided an economical tool for these of the project tasks

Human Factors Experiences in Context - Comparing Four Industrial Cases Using a Soft Systems Framework

Abstract: In industrial production companies, the practice of assigning responsibility for human factors and ergonomics (HFE) to specific professionals (referred to as HF agents in this paper) may take on various organizational forms. This interview study examines the extent to which HF agents are able to give input towards the design of new production systems in different industrial sectors. The present paper reports on how HF agents work in four Canadian case companies from the Automotive, Nuclear Power, Poultry and Auto parts sectors. A stratified soft-systems framework was used to guide the comparison of the four case companies regarding the HF agents’ positioning in their companies and how this influences their work practices. HF agents and a cluster of 2 -3 surrounding colleagues with adjacent responsibilities were interviewed. Results showed that company context-specific factors such as procedures, collegial relations, processes and culture all heavily influence the “infrastructure” the HF agents can make use of to advance and sustain a human factors/ergonomics agenda. This includes vertical support in the company hierarchy (management support from top-down, employee acceptance from bottom-up), available tools and methods for demonstrating HFE benefits, and proceduralized accountability for HFE in projects. The companies that report positively on being able to address HFE issues proactively have HFE input integrated procedurally into new project start-ups, and the HF agent has a sign-off role. These companies have also, on a high organizational level, established linkage between HFE improvements and business objectives
