Ubiquitous computing and global connectivity via the internet and the worldwide web raise new ethical as well as social questions and issues, and often require new interpretations of, and a fresh look at existing ones. In this paper we consider the teaching of Computer Ethics (CE) to our computing students. We review issues such as why the teaching of CE is important, how this should be done in...

A quantum computer (QC) can operate in parallel on all its possible inputs at once, but the amount of information that can be extracted from the result is limited by the phenomenon of wave function collapse. We present a new computational model, which differs from a QC only in that the result of a measurement is the expectation value of the observable, rather than a random eigenvalue thereof. S...

This paper discusses the design and development of worksheets for helping notebook computer (NBC) users to compute NBC and workstation adjustments so as to assume an appropriate seated posture. The worksheets (one for male users, the other for female ones) require the following information: body height, NBC screen size, work surface height, and seat height. The worksheets contain tables for est...

We propose a control method for the optical components of a dynamically reconfigurable optical platform, the ternary optical computer (TOC). The optical components are made of liquid-crystal cell arrays (LCCAs) and polarizers, so the control method is for generating the pilot signals of the LCCAs to meet user demands. In this work, we first briefly introduce the TOC theory, the modules in the T...

objective: the aim of the current study was to assess the impact of computer games and computer-assisted type instruction on dictation scores of elementary school children with attention deficit – hyperactivity disorder (adhd). method: in this single-blind clinical trial, 37 elementary school children with adhd, selected by convenience sampling and divided into group i (n=17) and group ii (n=20...

Ambient assisted living environments are full of human attention demanding applications. The introduction of wireless solutions in the assisted living area brings convincing advantages in terms of staff burden reduction, observation reliability and treating measures response time. The paper identifies some typical application requirements. Applicability analysis of existing solutions is made. Z...

Computers have been used for language teaching ever since the 1960's.Learning a second language is a challenging endeavor, and, for decades now, proponents of computer assisted language learning (CALL) have declared that help is on the horison. We investigate the suitability of deploying speech technology in computer based systems that can be used to teach foreign language skills. In this case,...

introduction: epidermoid tumors comprise 1% of intracranial tumors. although reported, intraosseous epidermoid tumors are even more rare. cystic lesions of the petrous apex are uncommon and surgically challenging; the most rare pathology is presumed to be epidermoid.rncase presentation: this is a case of a 61-year-old woman with a large skull-base tumor extending inferiorly from the c1-c2 artic...
