In the last few years, researchers have begun to study the use of Deep Neural Network (DNN) to identify different types of modulation, and by using it the task has become easier, and we can get a significant improvement in the classification performance compared to many traditional methods. In this paper an automatic modulation Classification model is proposed where deep learning is used to classify different types of modulation at different signal to noise ratios (SNRs), where we optimize the conventional convolutional neural network (CNN) architecture of O’Shea (2016) [1] by selecting the values of the CNN hyperparameters that result in obtaining the best accuracy for each SNR. The optimized model uses CNN4 that increases recognition accuracy of radio modulation over O’Shea’s mode.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125555735","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}

Efficiently purchasing such a critical issue is a challenge. Time, effort, and expenses are spent to select the most appropriate required medical equipment. Also, this selection may not do in the best way. Therefore, planning for a public tender is essential to select the most appropriate required medical equipment. In this paper, an automated evaluation system based on standardization to select the most appropriate medical equipment from presented offers is presented. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is used to evaluate the offers of medical equipment considering its resultant scores. Further, a software program is designed and implemented to evaluate the offers in terms of general, technical, and financial criteria. Each criterion has a set of evaluation points. A score index is generated for each criterion separately. The Emergency Care Research Institute (ECRI) is selected to be the technical reference for medical equipment specifications. In application, a set of medical imaging equipment such as X-Ray, Computed Tomography (CT), MRI, and ultrasound are used to test the software program. The results demonstrate a convenient utilization of the program considering the goal of this study. To improve the healthcare services in hospitals, the automated evaluation system based on standardization presents an automated platform to introduce, evaluate, and rank the offers of medical equipment.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124348250","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}

AVR microcontroller has been used to linearly control the speed of the stepper motors in three phases, accelerating from zero to its steady state speed, steady state speed and decelerating until stop. The proposed work makes any required speed profile easy to be obtained and fulfilled in real time, such as the profile needed for a single long acceleration phase throughout the most of the length of tank which is needed in the experimental work for added inertia measurement purpose. A general case to reach an assigned constant speed for hull drag measurements with two different phases of acceleration and deceleration is introduced.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124139537","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 RNS-OFDM system performance is compared to the Single-Carrier Frequency Division Multiple Access (SC-FDMA) communication system, where, in both techniques the signal PAPR is decreased through reducing the signal amplitude and the ICI noise is reduced through the need of less number of sub-carrier representations in the communication system. Consequently, the overall signal distortion and the Bit Error Rate (BER) is reduced and thus the received Signal-to-Noise Ratio (SNR) shall be improved. The paper analyzes and evaluates the RNS-OFDM and the SC-FDMA systems, through measuring the BER, PARR, and Carrier-Interference-Ratio (CIR) for both systems. Furthermore, the RNS coding is added to the SC-FDMA technique and the system performance is further evaluated.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127752772","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}

First of all, the micro turbojet engine discrete model is identified. System identification technique utilized real data obtained from jet cat P200sx engine running experiments. Digital PID controllers are mostly used for controlling these engines. The tuning techniques for digital PID controller parameters are of a great interest. Two tuning techniques are used in this paper to tune the PID controller parameters for the discrete model obtained. In the first, model based local optimal control technique is used to tune the PID controller parameters around certain operating points along the whole range. This technique is used for the first time with the concerned engine. The gain scheduling is used to manage the controller parameters around these operating points. In the second technique, genetic algorithms are used at different operating points along the whole range of operation. Also, the gain scheduling is used to manage the controller parameters around these operating points. The two tuning techniques are compared in Matlab simulation environment. The comparison is based on each controller robustness against noise effect and disturbance rejection. The simulated results are discussed and show better behavior for the digital PID controller tuned using model based local optimal control.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124582213","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}

Precisely the image quality is the result of a complex relationship among the configuration and design parameters of the telescope and detector units, imaging mode, atmospheric conditions and platform status. All these parameters have direct influence on images quality specifications in terms of spatial resolution, radiometric resolution, spectral resolution, signal-to-noise ratio (SNR), and modulation transfer function (MTF). In addition, the configuration and design parameters of the telescope and detector modules/units have direct influence on the camera weight and volume. Since the launch of the high-resolution satellite IKONOS-2, there has been an increasing demand for high spatial resolution data for various applications. This paper focuses on a comparison study among passive electro-optical remote sensors for earth observation launched in the last twenty years. The comparison study covers the configuration and design parameters of the camera including optical telescope schemes, detector types, and weight.

Multirotors can achieve several tasks and missions with high efficiency and durability. One of the most important missions for the multirotors is the surveillance of some areas of interest. This paper presents four novel optimal time-dependent mission planning formulations for a given number of hybrid multirotors in a 3D environment. The first two formulations are concerned with minimizing the overall time of a planned mission. On the other hand, the other two formulations minimize the total mission latencies in-between tasks. Typically, planning a mission initially starts with assigning a starting point as a ground control station (GCS), from which a given number of homogeneous hybrid multirotors should start their missions. Each mission is composed of a set of way-points to be visited once by one of the multirotors while minimizing the overall time or the total in-between latencies needed to accomplish the mission. The first novel formulation optimizes the overall mission time. The second formulation is then introduced with a given threshold mission time, and the number of sufficient multirotors to accomplish this mission is required to be optimized. This given threshold mission time is precisely considered depending on the multirotors endurance. These two formulations are based on Travelling Salesman Problem (TSP). However, the third and fourth formulations are introduced to tackle the problem from the minimum latency point of view. The third formulation is a novel formulation to introduce and clarify the overall minimum latency problem with only one multirotor. Whereas the fourth formulation tackles the same problem but with more than one multirotor. The third and fourth formulations are based on the travelling repairman problem (TRP), or what is known by the delivery man problem (DMP). The results of all the aforementioned formulations results are presented in a comparative form.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122948004","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}

LDPC codes are designed for their high error correcting ability. Meanwhile, the error floor of LDPC codes cannot satisfy the significant low error rate requirements of flash memory applications. Therefore, we take into account a concatenated BCH and LDPC coding system for the potential usage of data preventive on flash memory. To solve this problem, the concatenation of BCH and LDPC code is performed. The result is a better balance between the potential to correct errors and the low error rate, which can be an optional coding structure. In this paper, our objective is to design a parallel BCH code concatenated with LDPC code to enhance BER and minimize the low error floor. Additionally, our purpose is to figure out the least number of BCH branches that achieve the best BER and consume the least hardware resources.","PeriodicalId":346636,"journal":{"name":"2020 12th International Conference on Electrical Engineering (ICEENG)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116702195","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}
