Controlling nonlinear systems is accomplished in several ways, mostly linearizing the system which may cause problems regarding the robustness of the controller. The controllers, on the other hand may be linear or nonlinear. This paper investigates the effects of nonlinearities on the robustness of various controllers (linear controllers, such as PID with first order derivative filter, state-feedback with integral control and, CRONE, and nonlinear controllers, such as smoothed first-order integral SMC) with an application on a DC motor. The motor’s model includes four types on nonlinearities (voltage saturation, current saturation, dead zone, and backlash deadband). The performance of the different controllers is presented and compared using the nonlinear model, the linearized model, uncertainty in the model, and harmonic load disturbance.","PeriodicalId":220641,"journal":{"name":"2018 IEEE International Multidisciplinary Conference on Engineering Technology (IMCET)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126886439","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}

It enables the detection and the classification of various components, including jaws, teeth, lesions and carries. However, available methods have demonstrated limited results due to the challenging complexity of the panoramic images. In this paper we propose a novel automatic segmentation method that separates maxillary and mandibular jaws with a shape-free model and distinguishes teeth using lines defined within a precise scheme. The developed approaches are implemented and tested over a database of dental panoramic radiographs. Obtained results demonstrate good performance and showed the suitability of the proposed method.","PeriodicalId":220641,"journal":{"name":"2018 IEEE International Multidisciplinary Conference on Engineering Technology (IMCET)","volume":"113 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124413856","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}

They are connected to the grid via power converters that require the knowledge of the grid voltage magnitude and phase in order to operate correctly. The values of the grid phase and voltage are usually calculated using Phase Locked Loop (PLL) techniques. However, the grid voltage may be distorted due to non-linear loads and urban expansion thus the need of a PLL robust toward voltage distortions. The conventional PLL technique does not present accurate results in front of these distortions thus the necessity of a technique able to cope with different grid faults. This paper presents the design and the dynamic behavior of a PLL method (MVF-DSOGIPLL) combining two main filters: the Multi Variable Filter (MVF) and the Dual SOGI-based quadrature signal generator (DSOGI-QSG) along with the conventional Synchronous Reference Frame PLL (SRF-PLL). This PLL is implemented on FPGA to verify the analytical results. Simulation and experimental results validate the efficiency of the proposed technique.","PeriodicalId":220641,"journal":{"name":"2018 IEEE International Multidisciplinary Conference on Engineering Technology (IMCET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128854244","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 three-dimensional FDTD simulation is used to predict the performance of the probe. The probe uses a circular shaped monopole antenna on a substrate for the transmitting and receiving antennas. The transmitter radiates a differentiated Gaussian pulse that propagates in the soil under investigation. The soil parameters are extracted by mapping the measured S21 parameter (amplitude and phase) to the values obtained from the FDTD simulation. Measuring the soil characteristics in-situ is crucial in applications such as Ground Penetrating Radar (GPR) where interpretation of the radar signal is highly dependent on the ground parameters. However, it should be noted that the designed probe will be used in a sample of landmine free soil, having the same properties of the soil to be tested for landmines with a GPR.","PeriodicalId":220641,"journal":{"name":"2018 IEEE International Multidisciplinary Conference on Engineering Technology (IMCET)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116980230","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}

ARC, based on the backstepping method, guaranties asymptotic output tracking and satisfactory transient response of the quadrotor motion in the face of uncertainties and disturbances. The control system architecture includes an outer loop where a PID controller is used to generate the position inputs, which are fed to the ARC-based attitude control system at the inner loop level. The controller design is validated against payload variation in both numerical simulation and experimentally on a quadcopter. The obtained results demonstrate the accuracy of the ARC design with a constant payload against a well-tuned fixed-gain PID controller, and the adaptation and robustness of ARC become evident when the payload is varied and tracking performance is maintained.","PeriodicalId":220641,"journal":{"name":"2018 IEEE International Multidisciplinary Conference on Engineering Technology (IMCET)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128157614","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 proposes a simplified web deployed treatment planning system providing two main platforms with updated tools and features, able to assist medical physicists and radiation oncologists in accomplishing three important steps of the treatment planning process: Contouring and delineation of the concerned structures, interpolation and 3D reconstruction, and finally treatment plan evaluation. The developed system is a unique treatment planning application deployed on the web using Microsoft Azure, making it accessible anytime and anywhere by the authorized medical doctors. In addition, the following system focuses not only on reinforcing the team collaboration through web accessibility, but also on providing accurate, efficient and user friendly tools able to cover the main treatment planning process steps with high accuracy and low time consumption.","PeriodicalId":220641,"journal":{"name":"2018 IEEE International Multidisciplinary Conference on Engineering Technology (IMCET)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134524519","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}
