CONTROLLING OF AN INDUSTRIAL ROBOTIC ARM

Most of industrial robots are still programmed using the typical teaching process, through the use of the robot teach pendant. In this paper is proposed an accelerometer-based system to control an industrial robot using two low-cost and small 3-axis wireless accelerometers. These accelerometers are attached to the human arms, capturing its behavior (gestures and postures). An Artificial Neural Network (ANN) trained with a back-propagation algorithm was used to recognize arm gestures and postures, which then will be used as input in the control of the robot. The aim is that the robot starts the movement almost at the same time as the user starts to perform a gesture or posture (low response time). The results show that the system allows the control of an industrial robot in an intuitive way. However, the achieved recognition rate of gestures and postures (92%) should be improved in future, keeping the compromise with the system response time (160 milliseconds). Finally, the results of some tests performed with an industrial robot are presented and discussed

Bianchi type-II cosmological model: some remarks

Within the framework of Bianchi type-II (BII) cosmological model the behavior of matter distribution has been considered. It is shown that the non-zero off-diagonal component of Einstein tensor implies some severe restriction on the choice of matter distribution. In particular for a locally rotationally symmetric Bianchi type-II (LRS BII) space-time it is proved that the matter distribution should be strictly isotropic if the corresponding matter field possesses only non-zero diagonal components of the energy-momentum tensor.Comment: 3 page

Finite Bending of Blocks

The problem of bending of a circular block with concentric hole into ellipsoidal shell is considered, and the earlier results have been obtained as particular cases

Security against Timing Analysis Attack

Timing attack is the type of side-channel attack involves the time taken to complete critical operations. Securing crypto processor from timing attack is critical issue. This paper implements the Bernstein’s Timing Attack and timing attack based on hamming weight. The countermeasures of Bernstein’s Timing attack are implemented in our experimental test bed and their performance is compared.  This paper also proposes the key recovery method based on timing attack using hamming weight of the key

Sensitization of indium-bromopyrogallol red system with cetyltrimethyl-- ammonium bromide .

820-822Indium-bromopyrogallol red (In-BPR) system is sensitized with cetyltrimethylammonium bromide (CTAB) and the buffers used for controlling the pH influence the system. A calibration curve, at 610 nm, is non-linear in the entire metal concentration range studied. However, the curve, at 620 nm, is linear for 0-23.2 μg In in 25 ml. Molar absorptivity of the complex, at 620 nm, is 4.0 x 104 mol-1 dm3 cm-1
