The high gain dual resonant textile microstrip patch antenna with extended ground plane suitable to be employed for satellite Ku band uplink and downlink communication applications has been proposed in this paper. The proposed textile antenna has been fabricated over the wearable textile material — Denim as a substrate having dielectric constant εr= 1.6. The radiating patch and the ground plane are designed using copper of thickness 0.05mm and conductivity of 5.58×106 Siemens/m. The designed textile antenna is dual resonant at 12.64GHz and 13.515GHz with operating bandwidth of 1.57GHz (12.4GHz–13.97GHz) and minimal return loss of −71.86dB and −26.28dB, respectively. The antenna has high gain of 8.25dB at 12.64GHz and 6.14dB at 13.515GHz and directivity of 7.97dBi at 12.64GHz and 5.8dBi at 13.515GHz. The proposed antenna has been designed and simulated using CST Microwave Studio 2014. The proposed textile antenna can be suitably employed for Ku-band applications in vehicle mounted earth stations (12.5GHz–12.75GHz), space research and VSAT applications (12.75GHz–13.5GHz). The simulated antenna has been practically fabricated and tested using E5071C Network Analyzer and anechoic chamber. It has been concluded that the practical results closely match with the simulated antenna results.

This paper demonstrates the design and performance analysis of the star shaped microstrip patch antenna. The proposed antenna design employs substrate of FR4 material having thickness and dielectric constant of 1.6 mm and 4.4 respectively. The proposed antenna design consists of a FR4 substrate, star shaped radiating copper patch and slotted ground forming star shaped microstrip patch antenna configuration. The ground has been placed on the lower surface of the substrate and the star shaped radiating patch rests upon the upper surface of the substrate. The proposed antenna has been designed using CST Microwave Studio 2014. The performance of star shaped antenna has been analyzed in terms of resonant frequency, return loss (S11), gain (dB), directivity (dBi) and percentage bandwidth. It has been observed that the antenna is resonant at 13.49 GHz with an impedance bandwidth of 430 MHz and an operating frequency range of 13.32 GHz–13.75 GHz. The proposed antenna has return loss of −45.78 dB at resonant frequency of 13.49 GHz. The antenna has gain of 6.36 dB, directivity of 6.16 dBi and percentage bandwidth of 3.18 percent at resonant frequency of 13.49 GHz. The proposed antenna has been fabricated and successfully tested for return loss using E5071C network analyzer and anechoic chamber. The simulated and experimental results have been examined and it has been concluded that the practical results closely match with the theoretical results. The proposed antenna can be suitably used for Radio astronomy, Radio location (Civil), Radio location (Military) and Satellite navigation system applications.

A new scheme on dynamic pricing of electricity in a smart grid is proposed in this research article. Also the consumer's demand behavior and response is analyzed. With the smart grid it is possible to determine and communicate the real time prices of electricity like other market goods and evaluate the variation in demand. Utility can exploit the natural human response that is reduction in demand by increasing the prices. The user consumption behavior has modeled into utility functions as per the concepts in the micro-economics. Thus the electricity consumption of each consumer has optimized such that the aggregate utility function of all consumers is maximized. The proposed algorithm is beneficial for consumers and the utility as shown by the simulation results.

FinFETs are new structures for scaling the devices at sub-nanometer regime to continue the Moore's law. To increase the performance of FinFETs, a dual metal gate with underlap concepts has been introduced. Moreover, its performance can be enhanced by spacers. The dual metal gate comprises of two different workfunction materials (Molybdenum and Tungsten) for double gate (DG) and triple gate (TG) FinFET structures with different underlap length (LUN) has been presented. The TG FinFET exhibits the better control of short channel effects (SCEs) over the DG FinFET device. The significance of the spacer with a variation of spacer length poses the use of dual-k spacer in TG FinFET device to procure the better performance such as high on-current (Ion), Ion/Ioff ratio and smaller subthreshold swing (SS), drain induced barrier lowering (DIBL). The simulation carried by SILVACO ATLAS, and it shows that TG FinFET with different combination of dual-k (smaller high-k length (Lhk), larger low-k length (Llk)) draws an attention for nanoscale application.

In the 21st century, GFRP composites have been successfully substituted majority of the traditional engineering materials and widely used in manufacturing sectors. As there are a number of favorable properties associated with GFRP composites; but machining of GFRP is significantly different as compared to other engineering materials, because, GFRPs are non-homogeneous in nature (which consist of distinctly different phases), so that their machining operation is characterized by uncontrolled intermittent fiber fracture causing oscillating cutting forces and critical bending stresses, poor surface properties due to crushed fiber or resin pull out. For effective use of any machining process, it becomes important to find optimum parametric setting to achieve improved quality as well as increased productivity. In this present context, a case study on optimal machining parameters selection has been reported to ensure high productivity as well as satisfactory surface quality of machined glass fiber reinforced epoxy composites. Utility function based on Taguchi optimization approach has been proposed in this research. During GFRP drilling, fiber breakage, entry and exit delamination are encountered as the major issues leading to decrease in product quality and overall productivity of manufacturing processes and products. Taguchi L16, 4 level orthogonal array have been used to study the influence of various combinations of process parameters Present work aims to conduct a case experimental research on drilling of GFRP (epoxy) composites in order to select the most appropriate process parameter combination by utility theory based approach to ensure satisfactory process performance yields as well as hole quality.

This paper exhibits the aptness of flexible Teflon material having dielectric constant £r=2.1 to be employed as substrate in the Microstrip patch antenna design. This paper presents two flexible Teflon substrates of thickness 0.5 mm and 1 mm, respectively. The antenna designs employ a Trident shaped copper patch on the top surface of dielectric Teflon substrate and a defected ground plane on the other side of substrate. In this paper, substrate and structure materials employed in the antenna designs have been retained identical, whereas the dimensions of antenna designs are distinctive. In this paper, the thickness of the substrate is varied and the effect on the bandwidth, directivity and gain of antennas are investigated. A thorough parametric analysis has been performed and it has been perceived that the gain and directivity of antenna increases by decreasing the thickness of substrate. It has been also witnessed that the resonant frequency of the designed antenna, shifts to lower frequency by employing thick dielectric substrate. The performance of Microstrip patch antenna has been compared in terms of directivity(dBi), gain(dB), return loss(dB), impedance bandwidth(GHz) and half power beam width(degrees). The antenna has been designed in CST Microwave Studio 2014 and has been fabricated and verified using E5071C Network Analyzer and anechoic chamber.
本文论证了介电常数为r=2.1的柔性聚四氟乙烯材料作为衬底用于微带贴片天线设计的适用性。本文介绍了两种厚度分别为0.5 mm和1mm的柔性聚四氟乙烯基板。该天线设计采用在介质聚四氟乙烯基板的上表面采用三叉戟形铜片，在基板的另一侧采用有缺陷的接地面。在本文中，天线设计中使用的衬底和结构材料保持相同，而天线设计的尺寸是不同的。本文研究了衬底厚度的变化对天线带宽、指向性和增益的影响。进行了彻底的参数分析，发现减小衬底厚度会增加天线的增益和指向性。研究还发现，采用厚介质衬底后，天线的谐振频率向低频偏移。从指向性(dBi)、增益(dB)、回波损耗(dB)、阻抗带宽(GHz)和半功率波束宽度(度)等方面比较了微带贴片天线的性能。该天线在CST Microwave Studio 2014中进行了设计，并使用E5071C网络分析仪和消声室进行了制作和验证。

The antenna has been designed in CST Microwave Studio 2014 and has been fabricated and verified using E5071C Network Analyzer and anechoic chamber.","PeriodicalId":410488,"journal":{"name":"2016 International Conference on Control, Computing, Communication and Materials (ICCCCM)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133649893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces the concept of distributed loss model for calculation of Locational Marginal Price (LMP) in electricity markets on the basis of Optimal Power Flow (OPF). This model has also been presented to address the mismatch issue at system reference bus. The DC Optimal Power Flow (DCOPF) model has been evaluated in this paper to calculate the Locational Marginal Price (LMP). Moreover AC Optimal Power Flow (ACOPF) model has also been used for comparison purpose. But to overcome the drawback of lossless DCOPF algorithm, distributed loss based DCOPF model has been proposed and compared with other OPF techniques. IEEE 30 bus system is used in power world simulator for LMP calculation.
