Sensors based Biomedical Framework to Monitor Patient’s Vital Parameters

Abstract: This paper presents the development of a biomedical system which measures the heart rate, pulse rate, respiration rate and transmits the data over a network for remote monitoring. The proposed system comprises of ECG, PPG and piezo sensors to acquire biomedical signals. The desired information from the signal is extracted by signal processing tools and soft threshold based peak detector, and transmitted to the remote monitoring station through GSM module. Several important experiments have been carried out and compared with standard results. Based on the obtained results, the proposed framework can be used eminently for remote health care.

Design and Analysis of 3-DOF Spatial Serial Manipulator for Warehouse Applications

Abstract: This paper presents a robotic solution for the labor-intensive and time-consuming task of order picking operation carried out in the warehouse of e-commerce industries. The novel design of manipulator which will be mounted on a mobile robotic platform is proposed. A 3-DOF spatial serial manipulator is designed for the said task. Furthermore, the structural analysis and optimization of all the links of the designed manipulator are done by using finite element analysis. Finally, the payload carrying capacity of the proposed manipulator is determined.

RA 123 s: Three metaphor-less Algorithms for Economic Load Dispatch Solution

Abstract: This paper presents Rao-1, Rao-2 and Rao-3 algorithms (RA-123) approach to elucidate Economic Load Dispatch (ELD) problem which has Ramp Rate (RRL), Valve Point Effect (VPE), Prohibited Zones of Operation (POZ), and losses of lines. Besides most of the algorithms which depend on algorithmic-specific parameters, the proposed algorithm is independent of algorithmic-specific parameters. The principle contribution of this paper is to minimize the total generation cost by satisfying several constraints such as generation limits, load demand, valve point loading effect, and transmission losses considering metaphor-less algorithms (RA-123). The objective with VPE is considered to improve the performance of ELD. This paper determines the performance of proposed RA-123 algorithms considering different constraints on each test case system and compares them. To explore, ability of proposed optimization algorithms, these are implemented on test networks having 6, 40 and 110 unit systems and outcomes are compared with results attained by prior optimization algorithms. The evaluation of results shows ability and efficacy of (RA-123) for solving ELD problem.
