JARINGAN KOMPUTER MASA KINI PART 1

Nowadays computer networks are very useful and also very much needed by people in this modern era for various purposes, ranging from business interests to entertainment interests. However, it turns out that the actual computer network was initiated decades ago.

Features of the Process of Stretch Forming Shells Convex-Concave Shape

It is proposed to use actual computer software systems, providing a visualization and automation of the wrinkling and visualization and automation of the results of the numerical finite-element modeling of stretch forming a convex-concave shape in view of the fact that the saddle-backed surface of the shell has two families of asymptotic real straight lines. Along these lines, the saddle-backed surface of the shell with convex-concave shape is easy to break up or riffles are formed along them. The objectives of computer simulation are to predict unwanted distortion geometric form of the shell because of wrinkling and to find a ways to minimize the deviations of its surface deviations from the required shape.

Implementation

In this chapter, we will present the technical aspects of atomistic spin dynamics, in particular how the method can be implemented in an actual computer software. This involves calculation of effective field and creation of neighbour lists for setting up the geometry of the system of interest as well as choosing a suitable integrator scheme for the SLL (or SLLG) equation. We also give examples of extraction and processing of relevant observables that are common output from simulations. Atomistic spin dynamics simulations could be a computationally heavy tool but it is also very well adapted for modern computer architectures like massive parallel computing and/or graphics processing units and we provide examples how to utilize these architectures in an efficient manner. We use our own developed software UppASD as example, but the discussion could be applied to any other atomistic spin dynamics software.

Marine Fuel Boiler System Design Platform

This design platform consists of a computer control, signal interface and PLC or IPC and other components. Signal interface consists of analog and digital input and output board composition, these boards are equipped with signal conditioning and terminal board, the input and output to meet industry standards, can be directly connected with the actual computer control system, this article will focus on the signal interface.

Optimal Prediction for Braking Speed of Urban Rail Vehicle

The accurate measurement of the speed of urban rail vehicle is the basis of normal operation of the train controlling. Since speed measuring devices of vehicle-borne is inevitably disturbed by the sensors or the external environment, the deviation between the measured speed and the actual value, which varies randomly, is impossible to eliminate. This paper utilizes the method of minimum variance prediction to predict the speed of the train. By this way, the variance of the deviation between the predicted value and the actual value of the speed can be minimized. The model of the speed of the train is also discretized, which overcomes the shortcomings that the transitional models and control theory are limited to theoretical analysis but cannot be used in the actual computer control systems. In the section of simulation, the article shows the actual simulation results, which prove that this method has strong practicability.

Design and Realization of Virtual Computer Cluster System

Virtualization technology has revolted the computer technology. In the paper, we present our virtual computer cluster. The components of computer cluster have been improved by virtualization technology from the actual computer server to virtual server instance. Virtual computer cluster includes front-end machine and the cluster nodes. The front-end machine can be physical machines or virtual machines; the cluster node can also be virtual or physical machine node. The front-end machine of the cluster communicates with the cluster nodes through physical or virtual network adapter. The front-end machine connects with the cluster management software in each node so as to monitor and control every physical or virtual node within the cluster. A single virtual computer cluster extends its resources with adding physical or virtual resources including computing resources, storage resources and etc. within secure and stabile occasions with special needs. The technology can be widely applied to cluster and parallel computing demand but with lower-cost system design scenarios.

Informing one-to-one computing in primary schools: Student use of netbooks

<blockquote>Although one-to-one laptop programs are being introduced in many schools, minimal research has been conducted regarding their effectiveness in primary schools. Evidence-based research is needed to inform significant funding, deployment and student use of computers. This article analyses key findings from a study conducted in four Year 7 classrooms in which students were provided with netbook computers as an alternative to more expensive laptop computers. Variable access was provided to students including computer to student ratios of one-to-one and one-to-two. Findings indicated that increased access to the netbook computers resulted in increases in computer usage by these students, compared with their minimal use of computers before the study. However, despite the increased access, actual computer usage remained limited. The article reports that factors contributing to the minimal use of computers included individual teacher agency, a crowded curriculum, and the historical use of computers. Implications for policy and practice are suggested.</blockquote><p> </p>

Closing the Gap: Proficiency vs. Perception

The gaps that exist between a students self-perceived computer skills, their actual computer skills, and the computer skills deemed important in business pose an interesting challenge for business schools, today, and for the foreseeable future. One strategy for managing these literacy gaps is developing curriculum that better tailors content to the evolving literacy of students. In an effort to operationalize this strategy, we have undertaken a study to measure the magnitude of the literacy gaps and the effectiveness of an introductory computer course required in our undergraduate business program. This paper presents the initial results of that study.
