In this paper, the feasibility of using active noise control inside personal computers is demonstrated by applying an adaptive filter to Hewlett-Packard’s Blackbird 002 Gaming PC. Conditions relating the control signals and the sound heard by an external listener are presented as a means of evaluating the hardware design before applying the adaptive filter. A multichannel stochastic adaptive fi...

Domain specific search engines have pleased many Internet users and have been keeping some companies alive. Lately, universities and some non-IT companies have been adapting to this technology. These organizations very often allocate small amount of money and small number of computers to search engine projects. The YASE! (Yet Another Search Engine) project is a domain specific engine running on...

Clustering is used in information retrieval systems to enhance the efficiency and effectiveness of the retrieval process. Clustering is achieved by partitioning the documents in a collection into classes such that documents that are associated with each other are assigned to the same cluster. This association is generally determined by examining the index term representation of documents or by ...

Personal construct theory provides both a plausible theoretical foundation for knowledge acquisition and a practical approach to modeling. Yet, only a fraction of the ideas latent in this theory have been tapped. Recently, several researchers have been taking a second look at the theory, to discover new ways that it can shed light on the foundations and practice of knowledge acquisition. These ...

Personal computers can be connected to peripheral devices using ports. Each port has an address of itself that is specific to it and is only accessed when called by the CPU. Different types of ports have different data carrying capacities. The fastest port available on present day PCs is the thunderbolt port. This review paper is dedicated to the understanding of the history, structure, uses an...

BACKGROUND Medical practitioners such as physicians are continuously exposed to the suffering and the distress of patients. Understanding the way pain perception relates to empathetic dispositions and professional quality of life can contribute to the development of strategies aimed at protecting health professionals from burnout and compassion fatigue. In the present study we investigate the w...

The author independently developed the Holistic Approach to Learning and Teaching Interaction over nine years of reflective teaching practice in the field of information systems and computing across three higher educational institutions. It has been taught on undergraduate and post-graduate degrees and doctoral programmes. Though its roots are in the computing field, the holistic approach can b...

Users with disabilities interact with Personal Computers (PCs) using Assistive Technology (AT) software solutions. Such applications run on a PC that a person with a disability commonly uses. However the configuration of AT applications is not trivial at all, especially whenever the user needs to work on a PC that does not allow him/her to rely on his / her AT tools (e.g., at work, at universit...
