Buch. Zustand: Neu. Neuware - Preferential Emergency Communications: From Telecommunications to the Internet, a professional monograph, is divided into three sections. The first describes systems and protocols that have been deployed as private networks for use by government agencies like the U.S. Department of Defense. This section also presents an in-depth discussion on MLPP. We then present current work in the area of Land Mobile Radio, commonly used by local emergency personnel such as police and fireman. This second section also describes systems that have been deployed over the public switched telephone network. Finally, the third section presents insights on trying to support emergency communications over TCP/IP networks and the Internet. In this last item we look into what IETF protocols can be considered candidates for change, as well as those protocols and applications that should not be altered.

Buch. Zustand: Neu. Neuware - Monitoring of public and private sites is increasingly becoming a very important and critical issue, especially after the recent flurry of terrorist attacks including the one on the Word Trade Center in September 2001. It is, therefore, imperative that effective multisensor surveillance systems be developed to protect the society from similar attacks in the future. The new generation of surveillance systems to be developed have a specific requirement: they must be able to automatically identify criminal and terrorist activity without sacrificing individual privacy to the extent possible. Privacy laws concerning monitoring and surveillance systems vary from country to country but, in general, they try to protect the privacy of their citizens. Monitoring and visual surveillance has numerous other applications. It can be employed to help invalids or handicapped and to monitor the activities of elderly people. It can be used to monitor large events such as sporting events, as well. Nowadays, monitoring is employ~d in several different contexts including transport applications, such as monitoring of railway stations and airports, dangerous environments like nuclear facilities or traffic flows on roads and bridges. The latest generation of surveillance systems mainly rely on hybrid analog-digital, or completely digital video communications and processing methods and take advantage of the greater of flexibility offered by video processing algorithms that are capable focusing a human operator's attention on a set of interesting situations.
