A growing volume of literature proclaims the benefits of e-commerce for construction organizations in developing countries. However, it is questionable on what are determinants of a successful implementation of e-commerce in such a context. Furthermore, lacking a model or a method through which to...

Remanufacturing has become a superior option for product recovery management system. It mainly consists of three stages: retrieval, reproduction, and redistribution. So far, many different approaches have been followed in order to improve the efficiency of a remanufacturing process. However, as the...

The development of new applications of electronic commerce (e-commerce) that require the payment of small amounts of money to purchase services or goods opens new challenges in the security and privacy fields. These payments are called micropayments and they provide a trade-off between efficiency and...

In this paper, the authors’ interest is focused on the scheduling problem on identical parallel machines with consumable resources in order to minimize the makespan criterion. Each job consumes several components which arrive at different times. The arrival of each component is represented by a...

Simulating the transmission of HIV requires a model framework that can account for the complex nature of HIV transmission. In this paper the authors present the current state of the art for simulating HIV with agent-based models and highlight some of the significant contributions of current research....

Ontologies are knowledge constructs essential for creation of the Web of Data. Good documentation is required to permit people to understand ontologies and thus employ them correctly, but this is costly to create by tradition authorship methods, and is thus inefficient to create in this way until an...

This paper investigates the introduction of location-based services by government as part of an all-hazards approach to modern emergency management solutions.

Predictions for Service Oriented Architectures (SOA) to deliver transformational results to the role and capabilities of IT for businesses have fallen short. Unforseen challenges have often emerged in SOA adoption. They have fallen into two categories: technical issues stemming from service components...

Software classifications have been created before with the purpose of keeping track of attack patterns as well as providing a history for the various vulnerable software packages. This article focuses on one single class of such attacks, conventionally known as “Time and State” attacks. The authors...

Recent studies of the growth in e-commerce retail sales examine mainly supply side factors, such as the application of information technology, low transaction costs etc. The author uses an empirical model that provides evidence of significant demand side factors which also help explain structural...

The old idea of segmented macroeconomics of the financial sector competing with the real economy is replaced by a new model, which manifests strong interaction, integration and co-evolution by circular causation relations between the monetary sector and the real economy with the bridging function of...

This paper introduces a web-based semantic tool that provides more detailed information about a term selected by the user of a web browser, the Clinical Eye. This tool was initially designed for the medical area of cardiology, which is still controversial in terms of vocabularies. Anontology has been...

Managing dynamic reconfiguration of software systems is a tedious task in the software development because of the substantially increasing need for continuously available systems even at runtime. In particular, the software architecture of dynamically adaptive systems must continuously adapt to varying...

In this paper, the authors study the parameter sensitivity of the technique of particles warm optimization (PSO) for the clustering of data, in particular the text. They experienced the PSO parameters by varying within a range of research and we noted the best result of clustering based on three...

Declarative approaches to process modeling are regarded well suited for highly volatile environments as they provide a high degree of flexibility. However, problems in understanding and maintaining declarative process models impede their usage. To compensate for these shortcomings, Test Driven Modeling...

In this paper, Information Balance between supply and demand of information is considered. In general, differences between informational transmitter and receivers are often observed, and it is not so surprising in daily life. However, it would give serious influences for the receivers to make decisions...

This case captures inventory management process in an Indian convenience store. Unlike retail stores in developed countries, Indian convenience stores are a special format of organized retailing, where retailers open multiple smaller stores in a town instead of one big centralised store. An excellent...

The School Board is strongly considering equipping each classroom in the school with interactive whiteboards. However, prior to...

This case describes the design and development process of a computer-based information system for the management of archaeological finds and related documents. Adaptive Structuration Theory is used as the conceptual framework to analyse the role and actions of different people involved in the design...

Organizations today are looking for new ways to support knowledge-sharing and learning activities among their employees by the use of IT. The case describes how inspectors share their work experiences, reflect upon them, and learn from each other at a distance by using stories, pictures, and documents...

This paper presents tests specially-designed for a cryptosystem based on chaotic continuous cellular automata (CCA). The degree of the cryptosystem security is assessed by evaluating its (i) stationarity, (ii) spectral fractal dimension, and (iii) surrogate data. These tools are verified with known...

Mismanagement of routing and deliveries between sites of the same company or toward external sites leads to consequences in the cost of transport. When shipping alternatives exist, the selection of the appropriate shipping alternative (mode) for each shipment may result in significant cost savings. In...

This paper examines the problem of distributed coverage of an initially unknown environment using a multi-robot system. Specifically, focus is on a coverage technique for coordinating teams of multiple mobile robots that are deployed and maintained in a certain formation while covering the environment....

For supporting the effectiveness and efficiency of the students’ learning and the educators’ teaching, as a favored approach in recent years, e-learning technology has been widely used in the academic institutes. However, with regarding to the students community, how much they use the e-learning...
