Abstract

MOOsburg is a community‐oriented multi‐user domain. It was created to enrich the Blacksburg Electronic Village by providing real‐time, situated, interaction, and a place‐based information model for community information. We are experimenting with an implementation fundamentally different from classic multi‐user domains object‐oriented (MOOs), supporting distributed system development and management, and a direct manipulation approach to navigation. To guide the development of MOOsburg, we are focusing on a set of community‐oriented applications, including a virtual science fair.

Abstract

The first article in the series (The Electronic Library, 3, 3, July, 1985 pp. 200–209) introduced the reader to microcomputer terminology and to the main components—hardware and software—of a microcomputer system. This second article is largely devoted to more detailed description of the main hardware components: processors, internal memory, buses, external memory, printers and communications hardware. The importance of ergonomic factors in vdu and keyboard design is stressed. Multi‐user and network configurations are compared. Finally, the discussion of the role of the operating system, introduced in the first article, is extended.

Abstract

Since 2007, the cloud computing term had been introduced to the information technology (IT) dictionary. The theme is attracting growing interest from both the IT world and the business players, who need to enhance information systems agility, reduced costs, or even less dependence on internal IT teams when they are judged too slow. However, the fact that cloud computing, as presented by providers, increases the agility, is unclear. Business Managers; IT professional, and academics are querying about relationship between cloud computing and IT agility. This chapter aims to answer two major concerns: Factors that influence cloud computing adoption in medium and large organizations, and the cloud computing role to improve the agility of information systems. This chapter argues that cloud computing impacts Information System (IS) performance by organizational capabilities (agility). One of the primary motivations of this chapter is the lack of fieldwork when considering how cloud computing improves the information systems’ agility.

Abstract

This article investigates the evolution of computing, with specific reference to the security issues involved. These issues are then taken further to determine the need for education in the workplace through an information security awareness program. Techniques borrowed from the field of social psychology, which have been largely ignored in current awareness programs, are highlighted in order to show how they could be utilized to improve the effectiveness of the awareness program.

Abstract

A parallel‐processor computer contains multiple CPUs that share such system resources as memory and disk storage. A parallel‐processor computer is expanded not by adding another computer, but by plugging another CPU into the computer. This technology offers expandability, compact size, high performance, high reliability, and moderate cost. The Sequent Balance Parallel‐Processor Computer is described in some detail. A fully configured Balance 21000 can execute 21 MIPS (million instructions per second). It implements the UNIX operating system, which has been widely adopted. As a result, many software packages for word processing and other applications are available from third‐party vendors. Performance tests conducted by CLSI, Inc. indicate that twenty concurrent users on a parallel‐processor system can perform CPU‐intense functions up to seven times faster than on a single‐processor system.

Abstract

Purpose

Cloud users can access services at anytime from anywhere in the world. On average, Google now processes more than 40,000 searches every second, which is approximately 3.5 billion searches per day. The diverse and vast amounts of data are generated with the development of next-generation information technologies such as cryptocurrency, internet of things and big data. To execute such applications, it is needed to design an efficient scheduling algorithm that considers the quality of service parameters like utilization, makespan and response time. Therefore, this paper aims to propose a novel Efficient Static Task Allocation (ESTA) algorithm, which optimizes average utilization.

Design/methodology/approach

Cloud computing provides resources such as virtual machine, network, storage, etc. over the internet. Cloud computing follows the pay-per-use billing model. To achieve efficient task allocation, scheduling algorithm problems should be interacted and tackled through efficient task distribution on the resources. The methodology of ESTA algorithm is based on minimum completion time approach. ESTA intelligently maps the batch of independent tasks (cloudlets) on heterogeneous virtual machines and optimizes their utilization in infrastructure as a service cloud computing.

Findings

To evaluate the performance of ESTA, the simulation study is compared with Min-Min, load balancing strategy with migration cost, Longest job in the fastest resource-shortest job in the fastest resource, sufferage, minimum completion time (MCT), minimum execution time and opportunistic load balancing on account of makespan, utilization and response time.

Originality/value

The simulation result reveals that the ESTA algorithm consistently superior performs under varying of batch independent of cloudlets and the number of virtual machines’ test conditions.

Abstract

Presents a basic idea about a flexible robotic hand for handling fabric pieces in garment manufacture, which is multi‐functional and useful for picking a fabric piece up correctly, transferring and setting it without slipping to any three‐dimensional point. The robotic hand employs a strain gauge sensor and is capable of sensing touch, of measuring the thickness of fabric and its tension. Robotic hands have more applications in computer integrated manufacturing.

Abstract

Web‐based technologies are rapidly becoming an integral part of the business fabric, interwoven into most departments and functional areas. However, the consequences of adopting these innovations, such as anticipated versus unanticipated and desirable versus undesirable consequences, warrant further exploration. This paper describes the experience of a contract service business after adopting a Web‐based collaborative technology to share information throughout the firm. User perceptions and attitudes towards this technology and its impact on time, control, and organisational change were explored via qualitative interviews. The results suggest that there were a number of consequences relating to these dimensions. We reflect on these consequences and offer suggestions based on the generalisability of the results. Further studies are identified that extend the exploration into the impact of Web‐based collaboration.

Abstract

Purpose

Load balancing is an important issue for a heterogeneous distributed computing system environment that has been proven to be a nondeterministic polynomial time hard problem. This paper aims to propose a resource-aware load balancing (REAL) model for a batch of independent tasks with a centralized load balancer to make the solution appropriate for a practical heterogeneous distributed environment having a migration cost with the objective of maximizing the level of load balancing considering bandwidth requirements for migration of the tasks.

Design/methodology/approach

To achieve the effective schedule, load balancing issues should be addressed and tackled through efficient workload distribution. In this approach, the migration has been carried out in two phases, namely, initial migration and best-fit migration. Using the best-fit policy in migrations helps in the possible performance improvement by minimizing the remaining idle slots on underloaded nodes that remain unentertained during the initial migration.

Findings

The experimental results reveal that the proposed model exhibits a superior performance among the other strategies on considered parameters such as makespan, average utilization and level of load balancing under study for a heterogeneous distributed environment.

Originality/value

Design of the REAL model and a comparative performance evaluation with LBSM and ITSLB have been conducted by using MATLAB 8.5.0.

Abstract

Purpose

Owing to the numerous part models and massive datasets used in automobile assembly design, virtual assembly software cannot simulate a whole vehicle smoothly in real time. For this reason, implementing a new virtual assembly environment for massive complex datasets would be a significant achievement. The paper aims to focus on this problem.

Design/methodology/approach

A new system named “Grid‐enabled collaborative virtual assembly environment” (GCVAE) is proposed in the paper, and it comprises three parts: a private grid‐based support platform running on an inner network of enterprise; a service‐based parallel rendering framework with a sort‐last structure; and a multi‐user collaborative virtual assembly environment. These components would aggregate the idle resources in an enterprise to support assembly simulation with a large complex scene of whole vehicle.

Findings

The system prototype proposed in the paper has been implemented. The following simulations show that it can support a complex scene in a real‐time mode by using existing hardware and software, and can promote the efficient usage of enterprise resources.

Practical implications

Using the GCVAE, it is possible to aggregate the idle resources in an enterprise to run assembly simulations of a whole automobile with massively complex scenes, thus observably reducing fault occurrence rates in future manufacturing.

Originality/value

The paper introduces a new grid‐enabled methodology into research on collaborative virtual assembly system which can make the best use of idle resources in the enterprise to support assembly simulations with massively complex product models. A video‐stream‐based method was used to implement the system; this enables designers to participate ubiquitously in the simulation to evaluate the assembly of the whole automobile without hardware limitations.
