基于Matlab APP Designer的计算机超频仿真实训软件

高职院校常因设备条件所限而无法进行计算机超频的实机操作，为此开发了计算机超频仿真实训软件。以当前计算机超频的主要技术方法和操作流程为基础，设计了软件功能和用户界面；利用实机超频样本数据构建广义回归神经网络模型进行超频性能预测。软件以Matlab编程实现，并用Matlab APP Designer完成界面制作和功能整合。将该软件集成于《计算机组装与维护》课程实训工具盘中，学生借以熟悉CPU和内存超频的操作流程、掌握主要参数设置和测试软件使用，收到了预期的实验效果。     

特别关注

AMD对CPU超频将不再设限 对CPU进行超频是电脑高手提高电脑性能的重要手段,CPU的两大生产厂商Intel和AMD都对此作出了种种限制。最近,AMD全球产品市场总监Steve Zika表示,AMD将逐步对所有的CPU产品取消超频限制,并且还会提供Over Drive超频软件和ACC高级时钟校准技术,帮助用户更方便地进行超频操作,这将大大提高AMD CPU的性能价格比,对竞争对手Intel也会造成不小的压力。     

另类超频

超频对于大多数DIYer们来说是一件再熟悉不过的事情了,外频、倍频、贴引脚、软跳线等名词早已背得滚瓜烂熟,各种CPU和主板的超频性能也都了如指掌,不过,我们最常使用的超频方法基本上都是在主板提供的选项中,设置一下BIOS或跳线,以改变CPU的外频和核心电压,至于能否超频成功,则要看经验和运气了。高手们会     

移动新天地 手机软件串串烧

超频降频随心所欲 手机很费电？跑3D游戏比较慢？当你的手机遇到类似问题时,对CPU稍加操作兴许就能解决了呢。超级兔子CPU超频大师是专门对Andfold设备中的CPU进行超频或降频的软件,通过加快CPU运作,你可以得到更快的速度,或者是降低CPu频率来节省电力。     

CPU功率由我算

对CPU施以“超频”大法,虽然可以有效提升CPU 的处理能力,然而在对CPU进行超频的时候,CPU的功率必然也会随之增加。并目,由于某些CPU先天体质不佳,还必须适当增加CPU核心电压才能超频成功。因此,大家一定非常想了解CPU在“超频”和“加压超频”之后, 其功率究竟增加了多少吧?即或是你没有超频, 但是了解一下自家CPU     

菜鸟学超频

提高CPU实际工作频率使之超过其额定值的做法就叫做CPU超频.CPU超频是最常见、最基础的超频手段.并能获得明显的回报。 CPU超频在原理上非常的简单:CPU主频=外频×倍频.因此只要提高外频、倍频数或两者同时提高就实现了CPU超频。     

慧眼识得超频显卡

显卡超频和CPU超频不一样。CPU超频除了CPU自身体质以外,主板、内存甚至电源都会一定程度上影响超频成绩。而显卡超频则主要受显卡先天条件的影响。如果说CPU超频靠的是运气和主板、内存等周边因素的话,那么显卡超频则更大部分要靠咱们的眼光了。     

最疯狂的液氮制冷

这种超频方法听起来挺玄,可真得很酷:使用双桶式液氮制冷装置将一颗主频为1.33GHz的AMD雷鸟处理器超频到了2.174GHz！ 喜欢超频的朋友可以过来看看,虽然这种情况对我们实际应用并没有什么太大帮助,但权当做是学习一下别人的先进经验吧。 在超频当中使用的是AMD的雷鸟1.33G(FSB 266MHz);需要注意的是这里使用了两块ASUS A7M266主板来对CPU供电,原因是:在超频到2GHz时CPU所需

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.     

一种自适应子融合集成多分类器方法

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008     

A human-computer interface for non-computer specialists

The COM teleconferencing system was designed to be easy to use for both beginners and people with much computer experience. A number of design choices in organizing the human-computer interface were considered very carefully. These design problems are not unique for teleconferencing applications, but will appear in many other developments of human-computer interfaces for non-computer specialists. This report discusses naming conventions, menu format, user commands, help facility and the treatment of ‘type ahead’ from the users.
