In addition, ephedrine, as well as its isomers and analogues are controlled substances as they are the main precursors of more potent stimulants, i.e. amphetamines. We are presenting a Hierarchical Cluster Analysis (HCA) application built for the automated recognition of ephedrines based on their spectra recorded with a portable infrared laser spectrometer operating in the 1405–1150 cm−1. The spectra have been preprocessed with a feature weight wE, which emphasizes the most relevant absorptions. The class identity of each compound was then assigned by using HCA, based on the scores obtained by subjecting the preprocessed spectra to Principal Component Analysis (PCA). Despite the narrowness of the spectral window in which the spectra are recorded, the system is very sensitive, as it detects all the controlled ephedrines. It is also quite selective, as it distinguishes ephedrines from other illicit phenethylamines, such as stimulant and hallucinogenic amphetamines.","PeriodicalId":276733,"journal":{"name":"2017 5th International Symposium on Electrical and Electronics Engineering (ISEEE)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132491786","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}

The use of classical or Li-ion batteries in the industry, mainly utilized in storage systems, is not a viable solution because these devices, after 2–3 years, lose their ability to store electricity and the materials employed are polluting, even banned in some countries. The European Union regulation like RoHS 1 and RoHS represent sometimes a real bottleneck. Fortunately in the last time on the market more and more are present electronic passive components like supercapacitors. The Supercapacitors (Electrochemical Double Layer Capacitors — EDLCs) are the promising solution for the future. They do not contain lead or other polluting materials on a side and on an other side they are able to storage large quantity of electrical charge. EDLCs have a very long lifespan (> 106 unloading cycles) and very small internal resistance, which allows charging and discharging at very high currents (hundreds of A). Also, another advantage of using EDLCs battery systems in power structures is a decrease of the weight of the entire system. We have simulated and analysed the behaviour of a 100F/12V EDLC system by connecting 6 supercapacitors (600F/2.5V) in series. In this context, using an EDLC system, we have obtained interesting results after the primary power source has been disconnected. The proposed model is in the R&D phase, but the test results are promising. EDLC is a very viable solution for use in a hybrid electric system such as a UPS or electric car.","PeriodicalId":276733,"journal":{"name":"2017 5th International Symposium on Electrical and Electronics Engineering (ISEEE)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122699051","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}

As a main contribution, this work proposes an intelligent algorithm derived from PSO. This algorithm has two main characteristics. The first one consists in the use of an improved version of PSO, namely Hybrid Topology Particle Swarm Optimization (HTPSO). The second characteristic is related to the kind of solved problems. The algorithm is devoted to the optimal control problems, even those who handle bilocal constraints concerning the state variables. In order to prove its efficiency, the HTPSO algorithm was tested on many optimal control problems. A case study is presented in the second part of this paper: the optimal control problem for a DC motor with bilocal constraints. In addition to the initial conditions, there are also final conditions related to the state variables.

Echoes originate from the ultrasonic waves generated inside a virtual environment which contains geometrical shape objects. The low complexity method is called RDT (Reaction Diffusion Transform) previously proved efficient in isolated speech recognition problems [4]. The classifier employed in this paper is also a low-complexity one (Fast Support Vector Classifier) previously developed by us in C++ and interfaced with Octave. Results are quite encouraging with 100% accuracy in discriminating circular versus square objects independent on their distance from the ultrasound speaker.
