Field surveillance is one of the most important applications for wireless sensor networks. Many sensors are deployed in a region of concern to detect any potential targets. On the contrary, intelligent target looks for the best path to traverse the sensing field for fear of being detected and leads to defunct surveillance. In this paper, we focus on how an intelligent target traverses the sensi...

In this paper we present a system for the exploration of video sequences. The system, GAMBAL-EVS, segments video sequences extracting an image for each shot and then clusters such images and presents them in a visualization system. The system permits to find similarities between images and to traverse along the video sequences to find the rellevant ones.

Slipping and Tripping Re exes for Bipedal Robots Gary N. Boone and Jessica K. Hodgins Abstract|Many robot applications require legged robots to traverse rough or unmodeled terrain. This paper explores strategies that would enable legged robots to respond to two common types of surface contact error: slipping and tripping. Because of the rapid response required and the di culty of sensing uneven...

Creative and technical considerations in building a musical instrument to traverse acoustical space and network space. Conceiving a musical instrument for heterogeneous space and democratic use requires implementation of diverse modes and techniques satisfying needs of tactile local presence, and tangible telepresence. The result is an artistic project destined for multi-site gallery installati...

Repeated measurements of density profiles and surface elevation along a 515 km traverse of the Greenland ice sheet are used to determine elevation change rates and the error in determining mass-balance trends from these rates which arises from short-term fluctuations in mass input, compaction and surface density. Mean values of this error, averaged over 100 km sections of the traverse, decrease...

Legged locomotion enables humans and animals to traverse difficult terrain with great agility. Their skills to overcome large obstacles are impressive and superior to those of stateof-the-art legged robots. Our motivation is therefore to develop novel control methods for quadrupedal robots to increase their performance in this regard. More precisely, we seek for motor skills for the quadruped r...

Abstract A statistical optimization based on experimental work was conducted to consider ultimate tensile strength (UTS) and elongation of dissimilar joints between AA5454 AA7075 by friction stir weld (FSW). The goal this is develop a comparative study the FSW parameters using different orthogonal arrays, i.e., L12 L16. Four correlated softening forging requirements (rotational speed, traverse ...

Abstract Aluminium Metal Matrix Composite (AMMC) has broad uses in the medical, aerospace, and automobile industries, which have long sought lightweight materials with superior designs improved properties to improve performance. This analysis aimed prepare an AMMC investigate its machining mechanical properties. The is produced using a stir casting process by reinforcing boron carbide titanium ...

In this paper, we present a system to perform automated mechanical diagnosis of a car's brake system. The diagnostic process is performed by using the Generic Tasks of Hierarchcial Classiication and Routine Recognition. A classiication hierarchy is used to represent the possible malfunctions of a car's brake system. The two Generic Tasks are used to traverse the malfunction hierarchy in an atte...
