The current study was a pilot study and attempted to add to the growing body of knowledge regarding inherent issues in computer forensics. The study consisted of an Internet-based survey that asked respondents to identify the top five issues in computer forensics. Sixty respondents answered the survey using a free form text field. The results indicated that education/training and certification ...

With individuals, organisations and Governments releasing large amounts of linked data, users have now access to an immense repository of highly structured data, ready to be queried and reasoned upon. However, it is important at this stage to ask questions like What do Linked Data users look for and how do they search for information? Understanding the information needs of users accessing such ...

Portal Catalogs is a popular means of searching for information on the Web. They provide querying and browsing capabilities on data organized in a hierarchy, on a category/subcategory basis. This paper presents mining techniques on user navigational patterns in the hierarchies of portal catalogs. Specifically, we study and implement navigation retrieval methods and clustering tasks based on nav...

Understanding user needs, requirements, architecture specifications, and design specifications for a system holds up-most importance in a systems engineering project. The early phase requirements engineering deals with elicitation of goals, objectives and environment of the system under development and determine the needs and requirements of the various stakeholders. The needs, requirements sho...

Solutions to real-world image-segmentation problems typically require many image-processing steps. Unfortunately, the user must decide how to construct this sequence of steps for a given problem. So far, no system has been proposed to make the construction of these processes \easy" for the user. As a result, segmentation processes are often laboriously developed by an image-processing expert. I...

Though information technology (IT) has offered tremendous benefits to enterprises all over the world, its adoption by small and medium-sized enterprises (SMEs) in Asia remains relatively low. There are relatively few examples in the Asian SME segment where high end IT and electronic business (e-business) applications are being used for core business operations and transactions. This non-adoptio...

In this study, the minimum number of antennas at each user is derived to obtain 2M degrees of freedom (DOF) in the M × 1 ×M multiple-input–multiple-output (MIMO) multi-user two-way relay X channels. Based on the design of beamforming vectors for the conventional signal space alignment scheme, it is shown that each user needs at least ⌈M − (M/2)⌉ antennas to obtain DOF 2M with the relay having M...

Tttis article addresses the use and benefits of ttie Critical Success Factor (CSF) methodology in identifying corporate information needs and, subsequently, in developing a corporate information systems plan. The conclusions presented are drawn from an analysis of a CSF study conducted at Financial Institutions Assurance Corporation (FtAC). Interestingly, ttie initial purpose of tttis study was...

This paper presents the material production of an EST (English for Science and Technology) course in an English training programme for architects and civil engineers. The programme was specially designed for the construction professionals whose needs were investigated and analysed by the trainers, ESP (English for Specific Purposes) specialists from the British Council and Chinese counterparts....

This paper deals with determining the linguistic competence of university students in EFL classes that are part of an English Studies degree. It suggests a language deficiency analysis (i.e., a combination of their target situation and their actual situation) to aid in the selection of language content to be taught. The proposed needs analysis makes use of the Oxford Placement Test (OPT), which...
