Intensive development of digital technologies coincided in time with the beginning of the new ERA in telecommunications. It made possible to formalize many proce- dures of data exchange and to atomize some opERAtions which made providing of serviceandmakeworkofmanytelecommunicationworkersmucheasier. Somenew telecommunication technologies were born out of the necessity for use of specific configurations of network elements and networks, as well as for a possibility of providing maximum characteristics of efficiency combined with high requirements to the stability of opERAtion, the overcoming of different catastrophic situations and deadlockconditions,such as failuresand ”pending”of the networkandthe like. The thresholdbetweeninformationsystems andtelecommunicationsystems has become practically invisible. It resulted in such a new term as ”infocommunication”

In the present ERA, low observability is one of the critical requirements in aerospace sector, especially related to defense. The stealth technology essentially relates to shaping and usage of radar absorbing materials (RAM) or radar absorbing struc- tures (RAS). The performance of such radar cross section (RCS) reduction tech- niques is limited by the bandwidth constraints, payload requirements, and other structural issues. Moreover, with advancement of materials science, the structure geometry no longer remains key decisive factor toward stealth.

We are in the ERA of ubiquitous computing in which the use and development of Radio Frequency Iden- tification (RFID) is becoming more widespread. RFID systems have three main components: readers, tags, and database. An RFID tag is composed of a small microchip, limited logical functionality, and an antenna. Most common tags are passive and harvest energy from a nearby RFID reader. This energy is used both to energize the chip and send the answer back to the reader request. The tag provides a unique identifier (or an anonymized version of that), which allows the unequivocal identification of the tag holder (i.e. person, animal, or items).

The present ERA of research and development is all about interdisciplinary studies attempting to better comprehend and model our understanding of this vast universe. The fields of biology and computer science are no exception. This book discusses some of the innumERAble ways in which computational methods can be used to facilitate research in biology and medicine—from storing enormous amounts of biological data to solving complex biological problems and enhancing the treatment of various diseases.

SystemVerilog 语言简介SystemVerilog是一种硬件描述和验证语言（HDVL），它基于IEEE 1364-2001Verilog硬件描述语言（HDL），并对其进行了扩展，包括扩充了C语言数据类型、结构、压缩和非压缩数组、接口、断言等等，这些都使得SystemVeri1og在一个更高的抽象层次上提高了设计建模的能力。SystemVerilog由Acce11ERA开发，它主要定位在芯片的实现和验证流程上，并为系统级的设计流程提供了强大的连接能力。下面我们从几个方面对SystemVerilog所作的增强进行简要的介绍，期望能够通过这个介绍使大家对SystemVerilog有一个概括性的了解。1.接口（Interface）Verilog模块之间的连接是通过模块端口进行的。为了给组成设计的各个模块定义端口，我们必须对期望的硬件设计有一个详细的认识。不幸的是，在设计的早期，我们很难把握设计的细节。而且，一旦模块的端口定义完成后，我们也很难改变端口的配置。另外，一个设计中的许多模块往往具有相同的端口定义，在Verilog中，我们必须在每个模块中进行相同的定义，这为我们增加了无谓的工作量。
