This paper considers localization of a source or a sensor from distance measurements. We argue that linear algorithms proposed for this purpose are susceptible to poor noise perfor...
Traffic telematics comprises services like traffic information, navigation, and emergency call services. Providers of such services need large spatial databases especially for the ...
DTDs are continuously updated according to changes of the real world. Let t be an XML document valid against a DTD D, and suppose that D is updated by an update script s. In gener...
Abstract. Highly nonlinear Boolean functions occupy an important position in the design of secure block as well as stream ciphers. This paper proves two new lower bounds on the non...
In this paper, energy detectors are developed for wideband and ultra-wideband (UWB) pulse position modulation (PPM). Exact bit error probability (BEP) formulas are derived under di...
