Very hard to design reusable Software
Design must be specific to problem on hand
Design must be general enough to address future problems and requirements
Almost impossible to do it right the first time
Experienced designers don’t reinvent the wheel
They use good solutions again and again
Find & use recurring patterns of classes &

Abstract-In this paper, simple autonomous chaotic circuits
coupled by resistors are investigated. By carrying out computer
calculations and circuit experiments, irregular self-switching phenomenon
of three spatial patterns characterized by the phase
states of quasi-synchronization of chaos can be observed from
only four simple chaotic circuits. This is the same phenomenon
as chaotic wandering of spatial patterns observed very often from
systems with a large number of degrees of freedom. Namely, one
of spatial-temporal chaos observed from systems of large size can
be also generated in the proposed system consisting of only four
chaotic circuits. A six subcircuits case and a coupled chaotic circuits
networks are also studied, and such systems are confirmed
to produce more complicated spatio-temporal phenomena.

Servlets and JavaServer Pages is the first complete guide to building dynamic Java-based Web applications using the new JavaServer Pages 2.0 and Servlets 2.4. Servlets and JavaServer Pages (JSP) provide a robust solution to developing large, complex Web applications, including multiserver projects. In addition to built-in security, portability, and a Web server, they offer developers the freedom to work with any operating system that supports Javabe it Linux, Windows, OSX, or Solaris.
This authoritative book begins by explaining how to set up a Servlet and JSP development environment, including a discussion of containers, Java support, and installing and configuring Tomcat. The authors then thoroughly explore servlets and JSP, including significant coverage of custom tag libraries, newly available filters, and popular servlet and JSP design patterns. Readers can then test-drive the knowledge gained by constructing a book-support Web site.

Once upon a time, cellular wireless networks provided two basic services: voice
telephony and low-rate text messaging. Users in the network were separated
by orthogonal multiple access schemes, and cells by generous frequency reuse
patterns [1]. Since then, the proliferation of wireless services, fierce competition,
andthe emergenceof new service classes such as wireless data and multimediahave
resulted in an ever increasing pressure on network operators to use resources in a
moreefficient manner.In the contextof wireless networks,two of the most common
resources are power and spectrum—and, due to regulations, these resources are
typically scarce. Hence, in contrast to wired networks, overprovisioning is not
feasible in wireless networks.

As we enter the next millennium, there are clear technological patterns. First, the
electronic industry continues to scale microelectronic structures to achieve faster
devices, new devices, or more per unit area. Secondly, electrostatic charge, electrostatic
discharge (ESD), electrical overstress (EOS) and electromagnetic emissions (EMI)
continue to be a threat to these scaled structures. This dichotomy presents a dilemma
for the scaling of semiconductor technologies and a future threat to new technologies.
Technological advancements, material changes, design techniques, and simulation can
fend off this growing concern – but to maintain this ever-threatening challenge, one must
continue to establish research and education in this issue.

《Effective C++：改善程序與設計的55個具體做法》(中文版)(第3版)一共組織55個準則，每一條準則描述一個編寫出更好的C++的方式。每一個條款的背后都有具體范例支撐。第三版有一半以上的篇幅是嶄新內容，包括討論資源管理和模板（templates）運用的兩個新章。為反映出現代設計考慮，對第二版論題做了廣泛的修訂，包括異常（exceptions）、設計模式（design patterns）和多線程（multithreading）。《Effective C++》的重要特征包括：·高效的 classes、functions、templates 和inheritance hierarchies（繼承體系）方面的專家級指導。·嶄新的 TR1 標準程序庫功能應用，以及與既有標準程序庫組件的比較。·洞察 C++和其他語言（例如Java、C#、C）之間的不同。此舉有助于那些來自其他語言陣營的開發人員消化吸收 C++ 式的各種解法。
