Aiming at the problem of DV-HOP algorithm with error and energy exhaustion, average hop distance is used for optimization, an improved recursion method to solve it. The first squares anchor nodes, proposes a forgetting factor optimize between secondly uses recursive operations replace nodes insufficient energy, so that localization process unknown can continue. Experimental results show compare...

This paper presents a statistical algorithm for cooperative multi-robot localization based on a propagating detection model. The problem of multi-robot localization consists of localizing each robot in a group within the same environment, when robots share information to improve localization accuracy. Our approach is based on a well-known probabilistic localization approach, the Markov localiza...

We describe a new framework and method for the optimal selection of anatomical landmarks and optimal placement of fiducial markers in image-guided neurosurgery. The method allows the surgeon to optimally plan the markers locations on routine diagnostic images before preoperative imaging and to intraoperatively select the fiducial markers and the anatomical landmarks that minimize the Target Reg...

This paper presents the use of radio-frequency identification (RFID) technology for the real-time remote monitoring of body temperature, while an associated program can determine the location of the body carrying the respective sensor. The RFID chip's internal integrated temperature sensor is used for both the human-body temperature detection and as a measurement device, while using radio-frequ...

One of the various human sensory capabilities is to identify the direction of perceived sounds. The goal of this work is to study sound source localization in three dimensions using some of the most important cues the human uses. Having robotics as a major application, the approach involves a compact sensor structure that can be placed on a mobile platform. The objective is to estimate the rela...

This paper studies the performance of block coding on an additive white Gaussian noise channel under different power limitations at transmitter. New lower bounds are presented for minimum error probability codes satisfying maximal and average constraints. These tighter than previous results in finite blocklength regime, yield a better understanding structure good limitation. Evaluation these sh...
