rapid advances in processing power, network bandwidth, and storage capacity, computer are increasingly becoming extremely complex. Consequently, it becomes expensive and for human beings to manually manage complex computer systems. This problem can be ly tackled by self-managing computer systems, which are intended to meet high nce requirements in a dynamic computing environment. In this paper,...

Studying examples is a natural and common way of learning, and students use examples extensively when acquiring new skills [1, 2]. However, the learning benefits of examples are unclear, some studies showing great benefits [3], but others indicating only ability to solve problems similar to the original examples [4, 5]. However, self-explaining examples, that is analyzing and generating justifi...

OBJECTIVES In both science and media, the adverse effects of a long duration of computer use at work on musculoskeletal health have long been debated. Until recently, the duration of computer use was mainly measured by self-reports, and studies using more objective measures, such as software-recorded computer duration, were lacking. The objective of this study was to examine the association bet...

Past research has demonstrated that the level of computer experience users have is the most valuable predictor in whether or not they will suffer computer anxiety symptoms, but this was not the case in the present study. No research was found which examined the correlates of computer anger symptoms. In the current study, the relationship between the computer use (frequency and duration), comput...

A computer model is described that explores some of the possible behavior of biological life during the early stages of evolution. The simulation starts with a primordial soup composed of randomly generated sequences of computer operations selected from a basis set of 16 opcodes. With a probability of about 10 -4, these sequences spontaneously generate large and inefficient self-replicating "or...

New varieties of computer architectures, capable of solving highly demanding computational problems, are enabled by the large manufacturing scale expected from self-assembling circuit fabrication (1012–1019 devices). However, these fabrication processes are in their infancy and even at maturity are expected to incur heavy yield penalties compared to conventional silicon technologies. To retain ...

A critical discussion is presented on the use of self-replicating program systems as tools for the formulation of generalised theories of evolution. Results generated by such systems must be treated with caution, but, if used properly, they can ooer us unprecedented opportunities for empirical , comparative studies. A new system called Cosmos is introduced, which is based upon Ray's Tierra 15]....

Applying biological concepts to create new models in the computational field is not a revolutionary idea: science has already been the basis for the famous artificial neuron models, the genetic algorithms, etc. The cells of a biological organism are able to compose very complex structures from a unique cell, the zygote, with no need for centralized control (Watson J.D. & Crick F. H. 1953). The ...
