城市设计规划对城市发展的意义

城市发展的好与坏与城市的设计规划有着巨大的联系,这是不容置疑的,发展好的城市的规划设计就是要比其他城市的规划设计更加的合理。但是在这个城市遍地的时代,不是所以的城市都发展的很好,这主要就是城市的设计规划的不同所导致的,譬如:城市中的道路;建筑;楼房的建设;环境的创建等,这些东西的不同直接导致了两个城市的发展结果截然不同,这就说明城市规划对城市的发展是有很大的意义的。

虚拟现实技术在虚拟校园中的应用研究

随着时代的飞速发展,科技的不断进步,人们越来越意识到虚拟现实的重要作用,校园是培养人才的地方,如何给学生更好地学习环境,更好的保障学生在上学时的安全,更加有效地提高学生学习的效率,都是可以通过虚拟现实的技术得以实现的。人们通过虚拟现实的技术,更好的更直观了解校园中一些具体的情况,获取相应的信息,以往仅仅只是对校园环境的模拟已经无法满足人们的需求,人们需要教学,教务,校园生活三者相结合的一种虚拟校园的出现,而目前的科学技术已经足以实现这样的效果,真实性,互动性,有着特有的情节是虚拟技术的一个很重要的表现形式。     

保障多媒体业务QoS的跨层无线资源管理

传统的无线通信系统空中接口的高层协议采用简单的分层结构,每层进行独立的设计和操作,各层间的接口是静态的。这种设计方法简化了网络设计,具有很好的通用性,但是无线通信系统的信道是随着时间、空间和频率而随机变化的,同时用户的多媒体业务和整个网络状态也是动态的、变化的,而传统的分层协议结构不能很好的适应无线通信的特点,不能保证用户多媒体业务的QoS（服务质量）,传输的可靠性和提高无线资源的利用率,本文针对此问题阐述了跨层无线资源管理的思想,跨层设计能够根据用户多媒体业务的QoS和信道的随机变化特性等,跨过层间功能进行优化,更好的保证了不同多媒体业务的QoS,利用各个用户间信道的独立随机变化的特性,最大化系统的传输效率。     

数据信息于无线传输之下的采集和控制

传统的传输数据的方式是应用有线的方式。传统的数据信息的传输方式存在一定的弊端,在这些弊端的存在以及时代的发展之下,我们进入了无线的时代。数据信息于无线传输的采集与控制的方式具有速度快,噪音小、效率高等优点,给我们的生活带来了巨大的便利。

Enhancement-mode GaAs m.o.s.f.e.t. on semi-insulating substrate using a self-aligned gate technique

A self-aligned gate notched channel GaAs m.o.s.f.e.t. structure on semi-insulating substrate is presented. Device operation is mainly in enhancement mode. The transconductance is comparable to enhancement-mode m.e.s.f.e.t.s, j.f.e.t.s and s.i.g.f.e.t.s; however, the output-current capability is essentially increased.

GaAs power f.e.t.s with semi-insulated gates

GaAs semi-insulated-gate f.e.t.s (s.i.g.f.e.t.s) have been fabricated by Ar+ bombardment in the gate region. The d c. characteristics and microwave performance are compared with those of conventional power m.e.s.f.e.t.s fabricated from the same slice. Up to 2.9W output power with 4dB gain has been obtained from s.i.g.f.e.t. devices at 8 GHz.     

Some results for an r.f.- and p.l.-modulated incoherent carrier

Possibilities of using incoherent carriers, amplitude-modulated by the message-modulated p.f.m., r.f.m. and p.l.m. have been investigated. It has been shown that, for noise bandwidths much smaller than the transmission bandwidth, efficient communication is possible, and s.n.r.s of 50?60dB are obtained for practical p.f.m.-a.m. and r.f.m.-a.m. systems. Some comparisons are also given.

V-shaped-gate GaAs m.e.s.f.e.t. for improved high-frequency performance

The idea of gate shaping in f.e.t.s was implemented into the GaAs-m.e.s.f.e.t. structure. A m.e.s.f.e.t. with 2 ?m gate length was fabricated, the measured m.a.g. data of which allow an extrapolation to an fmax of about 45 GHz.     

Circuit model for the GaAs m.e.s.f.e.t. valid to 12 GHz

A new equivalent circuit is given for the GaAs m.e.s.f.e.t., which includes resistive loss in the feed back elements. The circuit values are given for several 1 ?m-gate GaAs m.e.s.f.e.t.s. A method for fitting s12 to the measured data is described. Finally, the gain and stability factor of several GaAs m.e.s.f.e.t.s. are extrapolated to 24 GHz from the present model.
