    Abstract : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. READ MORE

  4. 4. The effectiveness of a full-mobility architecture for wireless mobile computing and personal communications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : George Yuejin Liu; KTH.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile Computing; Mobile-API; Mobile Agent; Mobile Floating Agent; Intelligent Agent; Full-Mobility; Mobility Architecture; Mobility Awareness; Location Awareness; Location Prediction; Mobile Personal Communications.;

    Abstract : The emergence of wireless mobile computing, especially the mobility of computers, introduces challenging new problems that were encountered in neither the design and implementation of conventional mobile networks or in fixed computer networks. A critical and challenging problem, for mobile computing and personal communications, is how to fully cope with the special characteristics of the mobile wireless environment, i. READ MORE
