Abstract:

It is shown that the concept of a Universal Computer cannot be realized. Specifically, instances of a computable function [Formula: see text] are exhibited that cannot be computed on any machine [Formula: see text] that is capable of only a finite and fixed number of operations per step. This remains true even if the machine [Formula: see text] is endowed with an infinite memory and the ability to communicate with the outside world while it is attempting to compute [Formula: see text]. It also remains true if, in addition, [Formula: see text] is given an indefinite amount of time to compute [F

Abstract:

As high reliable equipment, on-board computer often has difficulties to evaluate its reliability. The paper put forward a simulation method to compute on-board computers reliability. The method uses a forced transition (FT) based reliability simulation model to deal with the on-board computers that have complex structure and diversiform characteristic parameters. The model is particularly suitable for the on-board computers which are composed of the components whose failure processes obey tub life curve. As an example, a prototype on-board computer was put forward and simulated using the model

Abstract:

Computers come from the word computer (to compute) which means to calculate. However, in accordance with the development of the times, computers have experienced many improvements, computers do not only function to calculate, but have been used to do various jobs and human activities, such as research, banking, and even education. With the help of computers and other supporting devices such as operating systems and applications, all types of work can be carried out quickly, precisely, and accurately. In completing these tasks, the computer does it automatically based on the instructions given

Abstract:

A computer virus is a type of malicious software program (“Malware”) that, when executed, replicates itself by modifying other computer programs and inserting its own code. Most of our computer systems, media devices and storages are victims of computer virus. Due to the continuous infections of computer systems, several studies and works are being done on the transmission, dynamics and epidemiology of computer virus. It is a major source of concern due to the importance and necessity of the computer system and the usefulness of the internet. Based on the menace caused by the virus to computer

This paper will discuss about the use of quantum computing in the computer engineering field to make computers reliable and fast to perform various typical computations. It is the process of using concept of quantum theory in computing algorithms and other computations and calculations along with the use of computer systems.

Monte Carlo methods are a class of computational algorithms that rely on repeated random sampling to compute their results. Monte Carlo methods are often used in simulating complex systems. Because of their reliance on repeated computation of random or pseudo-random numbers, these methods are most suited to calculation by a computer and tend to be used when it is infeasible or impossible to compute an exact result with a deterministic algorithm. In finance, Monte Carlo simulation method is used to calculate the value of companies, to evaluate economic investments and financial derivatives. On

Abstract:

Computers are encountered increasingly in the clinical setting, including during aphasia rehabilitation. However, currently we do not know what people with aphasia think about using computers in therapy and daily life, or to what extent people with aphasia use computers in their everyday life. The present study explored: (1) the use of computers by people with aphasia; and (2) the perceptions of people with aphasia towards computers and computer-based therapy. Thirty-four people with aphasia completed an aphasia-friendly paper-based survey about their use of computers before and after the onse

<p style="text-align: justify;">During COVID-19 in Athens, Greece, 535 general education and 170 special education teachers were tested for computer use self-efficacy, ICT competence, and computer attitudes.

Abstract:

Research in the area of computer anxiety has traditionally concentrated on the younger adult. In this study older adults (55 years and over) were compared to younger adults (30 years and under) on levels of computer anxiety and computer experience. Subjects in the study completed a demographic and computer experience questionnaire, and two computer anxiety scales. Previous research findings indicating a negative relationship between computer anxiety and computer experience was replicated for both young and older adults. Additional findings indicated that older adults were less computer anxious
