The resultant models are nonlinear, and their behaviour depends on their stability and control derivatives found during the analysis. The main result present how the eigenvalues of the linearised model in equilibrium evolve for the angles of attack within the flight envelope. Since the original instrumented model behaviour exhibit undesired characteristics, we propose modifications of the original aeroplane and present the results.

This device began to be used in the '60s in digital and analog configurations in a variety of reliable applications, either supported on the non-volatile or volatile property of this transistor. This is achieved by injecting/extracting charge to/from the floating gate through electrical mechanisms like Fowler-Nordheim Tunneling (FNT) or Channel Hot Electrons (CHE). This work shows that the same as with the mentioned mechanisms, I-V characteristics can also be modulated with physical rather than electrical phenomena, like the photonic one, among others. A simple amplifier configuration was used, using discrete components like a small solar cells module and an integrated photo sensor. After measurement of the corresponding transfer curve of the amplifier, a curve shift was obtained thanks to the VOC generated in the discrete device after illumination of the components, giving support to the hypothesis considered in this work, which can lead to a research work where integrated FGMOS transistors can be coupled to an integrated photo sensor, using a standard CMOS technology.","PeriodicalId":285464,"journal":{"name":"2016 13th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115676022","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}

A main issue with such many objective optimization problems is that, due to space dimension, their solution sets (so-called Pareto sets) can not be computed or entirely approximated. In this paper we present a tool, Pareto Explorer, specifically adapted for a preference-based local exploration of solutions, to deal with linear many objective optimization problems. The Pareto Explorer is able to steer the search from a given solution considering user defined directions, or preferences along the (highly-dimensional) solution set-turning the decision making process more intuitive. We demonstrate the effectiveness of the the proposed method on some benchmark examples.","PeriodicalId":285464,"journal":{"name":"2016 13th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116594098","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}

One of them is the form how nodes are distributed, from random positions to a predetermined location of nodes. In this concern, those applications that require a specific planning of position of nodes usually consider simple characteristics of the antenna radiation pattern (an isotropic pattern, for instance). Depending on the particular application, nodes can be located not only at different distances from each other, but also at different heights, which could introduce less gain due to the vertical pattern of the antenna. Thus, this paper addresses the importance of considering the vertical radiation pattern of antennas on simulations of wireless sensor networks, when nodes have a fixed position. By taking a commercial antenna and its measured radiation pattern, an evaluation of the achieved gain and its impact on a link budget is presented.","PeriodicalId":285464,"journal":{"name":"2016 13th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131311371","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}

Structural analysis showed presence of Cu2-xS phase in the CZTS nanocrystals synthesized for lesser than 2 h. As the reaction time proceeds, Zn2+ and Sn4+ cations diffuse into Cu2-xS lattice and lead to the formation of single phase CZTS. Morphological analysis showed CZTS nanocrystals with irregular shape as well as inhomogeneous size distribution with respect to various reaction time.

Metal-insulator-semiconductor-like structures were fabricated with n+ polysilicon and aluminum as gate and substrate electrodes, respectively. SRO films were thermally annealed at high temperature to induce the silicon agglomeration. The effect of SRO thickness (tSRO = 24, 53 and 80 nm) on the electrical and electro-optical properties of LECs is analyzed. A high conduction state (HCS) is observed at low electric fields (E) for SRO films with 24 and 53 nm of thickness. The current drops from that HCS to a low conduction state (LCS) when a certain electric field is reached. The HCS at low E is not observed as the SRO thickness is increased. A broad visible electroluminescent spectrum is observed on LECs when the electric field is larger than 7.5 MV/cm2 through the Fowler-Nordheim mechanism. Moreover, an intense infrared (IR) electroluminescent peak is observed in LECs when the SRO film is decreased. This IR EL peak could be related with the silicon substrate emission.","PeriodicalId":285464,"journal":{"name":"2016 13th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"06 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129079183","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}
