As more and more real wireless sensor networks (WSN) applications have been tested and deployed recently, the research community realizes that several issues need to be revisited from practical angles. In this paper, we focus on designing a general energy-efficient, load balanced, fault-tolerant, and scalable routing protocol. First, we abstract four fundamental requirements of any practical ro...

In 2008, Nao robots played soccer for the first time in Robocup in Suzhou, China. This robots are developed to play soccer and for entertainment (e.g. dancing, interacting with children). This report presents that using different motion planning methods (e.g. inverse kinematics, RRTs, potential fields), allows this robot to do more complicated tasks like boxing. The main challenge is to deal wi...

The aim of this paper is to fabricate micro-gears via laser shock punching with Spitlight 2000 Nd-YAG Laser, and to discuss effects of process parameters namely laser energy, soft punch properties and blank-holder on the quality of micro-gears deeply. Results show that dimensional accuracy is the best shocked at 1690 mJ. Tensile fracture instead of shear fracture is the main fracture mode under...

In the area of metal forming the production of micro-components in huge quantities by cutting plays a central role. These components are often manufactured on modified mechanical high speed presses with stroke rates of up to 4,000 strokes per minute (spm) and punching forces of up to 2,000 kN. In terms of maximum cutting force and overall size of the punching machine, this may represent a signi...

Gilles de la Tourette’s syndrome, or Tourette’s syndrome (TS), is a neurodevelopmental condition characterized by multiple motor and vocal tics, which appear in childhood and are often accompanied by behavioral symptoms [1]. The chronic presence of at least two motor tics and one vocal tic since childhood is recognized as the key feature of Tourette’s syndrome [1,2]. Motor tics (facial grimacin...

A variety of automatic and semiautomatic measuring devices with print-out, card-punch, and paper-tape capacity have been used in the analysis of lateral head radiographs, posteroanterior head radiographs, and oblique-jaw views. Such devices include the tape-printing GOAT ' the card punching GADRS-4 and GADRS5,T and the OSCAR.T These automatic measuring instruments have satisfactory readout accu...

Abstract In flat-slab frames, which are typically designed as secondary seismic structures, the shear failure of slab around column (punching failure) is governing mode limits deformation capacity and can potentially lead to a progressive collapse structure. Existing rules predict flat frames resist imposed lateral displacements without losing capability bear gravity loads have been derived emp...

Sports involving throwing, striking and kicking activities, such as tennis, squash, baseball, football, among others, demand the production of maximum speed at the end of the distal segment in a kinematic chain. Research done on the biomechanics of these various, yet somehow similar sporting techniques, suggests that athletes generate large hand and foot speeds as a result of a proximal-to-dist...

This paper presents a new digital communication system called turbocodes m-binary. The advantages of building m-bit compared to the conventional scheme of turbo codes (m = 1), are varied: better convergence of the iterative process, larger minimum distances less punching, lower latency, robustness to the sub-optimality of the decoding algorithm, especially when the MAP algorithm is simplified b...

In this study accumulative roll bonding (ARB) process up to 8 Cycles (equivalent strain of 6.4) at ambient temperature was used in order to improve the mechanical properties of Commercial purity titanium (CP-Ti).Several experiment has been done and Mechanical properties of specimen has been discussed. For investigating optical microscope punching and hardness test were utilized. This is the fir...
