The Capsule Reviews are intended to provide a short succinct review of each paper in the issue in order to bring to a wider readership. The Capsule Reviews were compiled by Fairouz Kamareddine. Professor Kamareddine is an Associate Editor of The Computer Journal and is based in the Department of Mathematical and Computer Sciences at Heriot-Watt University, Edinburgh, UK.
... Reliability and Performance of Mirrored Disk Organizations -
Disk mirroring or redundant array of independent disk (RAID) level 1 is a popular paradigm to achieve fault-tolerance and a higher disk access bandwidth for read requests. We consider four RAID1 organizations: basic mirroring (BM), group rotate declustering (GRD), interleaved declustering (ID) and chained declustering (CD). The last three organizations provide a more balanced disk load than BM when a single disk fails, but are more susceptible t... A Review of SIMD Multimedia Extensions and their Usage in Scientific and Engineering Applications -
The volume and complexity of data processed by today's personal computers are increasing exponentially, placing incredible demands on the microprocessors. In the meantime, computing performance that can be achieved by increasing the clock speed of a microprocessor is reaching to physical limits thus making the architectural solutions more prominent. Due to this an important architectural feature is added to recent microprocessors, single instruc... Affordance and Symmetry in User Interfaces -
Affordance is a widely used term in human–computer interaction (HCI) that, while familiar and attractive, does not have a clear operational definition. Using the mathematical concept of symmetry, this paper shows that it is possible to begin developing an operational definition for significant aspects of affordance by forming the theoretical concept of symmetry-affordance. The proposed definition restricts symmetry-affordance to particular... The Collective Index: A Technique for Efficient Processing of Progressive Queries -
The emergence of modern data-intensive applications requires sophisticated database techniques for processing advanced types of user queries on massive data. In this paper, we study such a new type of query, called progressive queries. A progressive query is defined as a set of inter-related and incrementally formulated step-queries. A step-query in a progressive query PQ is specified on the fly based on the results of previously-executed step-q... The Availability of Complemental k-Coteries -
k-Coterie is a graceful concept to solve the distributed k-mutual exclusion problem. The k-mutual exclusion algorithm adopting k-coteries could provide the fault-tolerant capability. The complementalness and the availability are two important metrics to measure the fault-tolerant capability of a k-coterie. Since those two metrics are defined under two different failure assumptions, for a given k-coterie, two independent works to measure those tw... Vertex-ordering Algorithms for Automatic Differentiation of Computer Codes -
In the context of Automatic Differentiation (AD) of functions represented by computer code via the vertex elimination approach first advocated by Griewank and Reese (On the Calculation of Jacobian Matrices by the Markowitz Rule. In Griewank, A. and Corliss, G.F. (eds), Automatic Differentiation of Algorithms: Theory, Implementation and Application, pp. 126–135. SIAM, 1991, Philadelphia, PA.), we present two approximate algorithms based on ... An Introduction to Reversible Latches -
Reversible logic has been suggested as one solution to the problem of power consumption in today's electronic devices. This paper addresses the issue of designing reversible latches and provides an overview and analysis of some proposed designs.
... Visual Cryptography Schemes with Reversing -
The Visual cryptography scheme (VCS) is a perfect secure method that encrypts a secret image by breaking it into shadow images. A distinctive property of VCS is that one can visually, without computation, decode the secret by superimposing shadow images. However, much of the contrast of the reconstructed image is lost. A different kind of VCS has been recently proposed by Viet and Kurosawa, called VCS with reversing, allowing participants to per... Synchronized Interactions in Spiked Neuronal Networks -
The study of artificial neural networks has originally been inspired by neurophysiology and cognitive science. It has resulted in a rich and diverse methodology and in numerous applications to machine intelligence, computer vision, pattern recognition and other applications. The random neural network (RNN) is a probabilistic model which was inspired by the spiking behaviour of neurons, and which has an elegant mathematical treatment that provide... The Future of Computer Technology and its Implications for the Computer Industry -
Progress in computer technology over the last four decades has been spectacular, driven by Moore's law which, though initially an observation, has become a self-fulfilling prophecy and a boardroom planning tool. Although Gordon Moore expressed his vision of progress simply in terms of the number of transistors that could be manufactured economically on an integrated circuit, the means of achieving this progress was based principally on shrinking...
