In this paper, we have developed a new heuristic algorithm for three machines flowshop scheduling problem using five parameters together. The parameters, which we have used in this paper, are separate setup times, transportation times, Job block, weight of job and specified rental policy. The main aim to introduce this algorithm is to obtain the optimal sequence to minimize the makespan, utilization times and rental cost of the machines. We used the Johnson's Techniques of three machines for developing this heuristic algorithm. A numerical illustration is also provided to verify the effectiveness of developed heuristic algorithm.

In this paper an ultra wideband bandpass filter with reconfigurable notches has been presented. It consists of a reconfigurable E to C shaped resonator centrally loaded on a multiple mode resonator (MMR). The MMR is constructed using stepped impedance resonator. Two notch frequencies are created by using reconfigurable E to C shaped resonator in order to reject these two interfering frequencies. Reconfigurability has been achieved by using a switch in the structure. The structure has been analysed for the two states of the switch reconfiguring E to C shape for ON and OFF states. By tuning the length of this reconfigurable E to C shaped resonator, the center frequencies of these notches can be changed.
本文提出了一种带可重构陷波的超宽带带通滤波器。它由一个可重构的E到C型谐振器中心加载在一个多模谐振器(MMR)上。MMR是用阶跃阻抗谐振器构造的。为了抑制这两个干扰频率，使用可重构的E到C型谐振器创建了两个陷波频率。通过在结构中使用开关，实现了可重构性。对开关的两种状态进行了结构分析，分别对开关的ON和OFF状态进行了E - to - C型重构。通过调整这种可重构的E到C型谐振器的长度，可以改变这些缺口的中心频率。

Correlation measure is an important indicator of the performance any code sequence family used for communication system. Frequency Hopping (FH) codes are similar in construction of Time Hopping (TH) codes used in Ultra Wide Band (UWB) communication systems. Since the development of TH codes is not yet fully established, in this paper an effort has been made to utilize FH code families as TH codes as the former are widely available in large numbers and have been dealt with in literature. This paper investigates the similarity between correlation properties of FH and TH codes. Lower bounds of auto correlation and cross correlation functions of TH codes have been derived and compared those with FH codes. It is found that the values of correlation functions for TH codes are higher than those for FH codes. This conclusion has been established through a case study using three well-established FH code sequence families.

An intelligent color sensing system has been developed. The developed system is capable of the measurement of color of building wall. The color sensing system is implemented using arduino processing unit with white Light Emitting Diodes (LEDs) and programmable Complementary Metal Oxide Semiconductor (CMOS) color sensor. The output of the color sensor is directly proportional to the light intensity of incident light and calibrated to measure the primary colors such as red, green, and blue. A graphical user interface (GUI) is developed for display the color of wall. The calibration of the Intelligent Color Sensing (ICS) system has been implemented successfully. The ICS system is easy to operate, energy efficient, accurate, and transportable.

In cognitive radio spectrum sensing is a fundamental problem. Under the case of uncorrelated noise different methods are used for spectrum sensing. In this paper we compare the performance of MP and eigenvalue based methods. In eigenvalue based method we find the threshold using random matrix theory (RMT). Marchenko-Pastur (MP) method use standard condition number (SCN) to find the threshold. Here we find the SCN by using eigenvalue parameters. Simulation shows that MP Law statistics improve the sensing performance.

Today's wireless environment is very dense to support enhanced performance, which is become heterogeneous in cell, applications, services, standards and technologies. This dense deployment of heterogeneous cells has a large impact on the power consumption of network. Thus, issue of energy efficiency need to be considered in perspective of deploy of several base station (BS) in the area. In 5G standard, massive MIMO architecture has been proposed to enhance energy efficiency (EE) of network. In this paper, we have considered the heterogeneous network (HetNet), where microcell, picocell and femtocell are coexist within macrocell. The macrocell BSs (MBS) are equipped with large array of antennas and all other BSs are supported with limited number of antennas. This work assumes users are supported by massive MIMO architecture, where MBS and few nearest BSs are participated. In this paper, we mainly investigate the impact of deployment efficiency of heterogeneous small cells BSs and, user association in a HetNet with massive MIMO to maximize the system energy efficiency (EE). Our results show that involvement of nearest BSs is greatly enhance the system energy efficiency (EE) and the deployment efficiency of small cells in macrocell environment also have impact on system EE.

Real-time detection of gait events play a vital role in movement dependent control applications such as rehabilitation for lower limb amputations. It also helps in determination of spatio-temporal and kinematic parameters. Gyroscopes, inertial sensors, magnetometers and foot sensors are popular in the detection of gait events. They need to be mounted carefully, or foot should be placed specifically on foot pressure during detection. This study presents a framework for automated detection of gait events from conventional videography using passive markers at Robotics And Machine Analytic Laboratory (RAMAN Lab). The proposed Passive maker based Gait event detection (PMGED) algorithm automatically detects heel strike (HS) and toe-off (TO); the timing of stance and swing phase; the number of the gait cycle. Ten healthy subjects are considered to evaluate the robustness and reliability of proposed algorithm. The method is comparable when evaluated against human expert detection.

Satellites are energized by the dc output power of solar panel. Every subsystem of a satellite requires stable and highly efficient power supply. The selection and design of an input filter is potentially important in power supply design. As the number of stages increases, the attenuation required will reduces; However the design complexity increases. This paper unveils the optimization of a two stage input filter for realizing a Phase Shifted Full bridge (PSFB) topology Electronic Power Conditioner for space applications. Attenuation challenges and filter interaction problems are tried to avoid with a novel optimization methodology. The experimental wave-forms and simulations in MATLAB and PSPICE are shown to validate the results.

Recent research shows that the diastolic part of cardiac cycle contains very weak murmurs caused by turbulent flow in the coronary artery diseases. This paper deals with the use of electronic stethoscope for the preliminary detection of coronary artery diseases (CAD). 3M Littmann 3200 model is used for recording of cardiac sounds of CAD and non CAD category. Cardiac sounds were analyzed in both time and frequency domain. Six features including two time domain and four frequency domain were extracted from each sound. Out of these features two frequency domain features namely spectral centroid and spectral roll off were identified as the potential features for discriminating CAD and non CAD sounds.

In this paper, a model - which uses Swarm Intelligence (SI) through the behavior of Ants is proposed. The model can be used to find safe paths to safe locations in such disaster-affected areas where the state rescue and relief teams may take some time to reach. The information generated (e.g., GPS logs at regular intervals) by stranded agents (victims), who have somehow managed on their own to reach safe locations, is used to find paths that can be suggested to other agents stranded in the disaster-affect areas. This is done through mobile-phones via web enabled services. The technique allows a large number of people to reach the safe locations on their own, which aids the ongoing state rescue and relief operations. Paths created by following the GPS log traces can be used to make new paths which are the hybrids of the previous paths created. Real life constraints will be considered such as capacity of safe areas, paths etc.
