A proposed method for solving reverse kinematics used to determine the angle values of the arm joints when traced in any path. Forward kinematics derived according to the D-H method (Devavit - Hartenberg) representation. The design of the dynamic model based on the Lagrange method. Computing the dynamic model is a very important step in the robotics world. The adaptive controller based on ANN optimized PID used to improve system response. We can compute the forward kinematics and reverse kinematics and trajectory planning by design a graphical user interface by using MATLAB, computing the forward and reverse kinematics by hand is not easy, so by using this design it is an easier way. The dynamic model used with the adaptive controller based on ANN optimized PID, this method tries to select the PID parameters, without needing to the robot manipulator mathematical model. The system performance results show better response when using the proposed controller, the maximum overshot is equal to zero and the raise time is reduced to 0.1 in joint 3 also the optimal settling time 0.2 in joint 1 the delay time is reduced to 0.1 in joint 1 and joint 5. These results are much better when compared with traditional methods such as traditional PID controller. This proposed algorithm improved the system parameters to the optimal values.","PeriodicalId":337954,"journal":{"name":"2021 International Conference on Advanced Computer Applications (ACA)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123188633","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}

With the fifth generation of wireless communications or (5G) and beyond networks, the need for beamforming is ever increasing because of the use of higher frequencies and the need to provide better coverage and better spectral utilization. Although many designs have been suggested to build hybrid beamforming, the Machine Learning (ML) based designs have attracted much attention recently because of the flexibility in coping with the wireless channel variations and user mobility they can attain when directing the transmission to the right direction during the communication process. In this paper, we describe the extended design of machine learning based hybrid beamforming for multiple users in systems that use millimeter waves (mmWaves) and massive MIMO architectures. The simulation results show that with the right amount of training data samples (channel feedback), the ML based hybrid beamforming architecture can achieve the same spectral efficiency (bits/sec/Hz) as the fully digital beamforming designs with negligible error for both single user and multi-user Massive-MIMO scenarios.","PeriodicalId":337954,"journal":{"name":"2021 International Conference on Advanced Computer Applications (ACA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114955822","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}

In this paper, the design and simulation of microstrip antenna with an arrays for gain enhancement were made. The suggested design is made up of four elements of microstrip antenna in rectangle shape which associated with an array pattern. The antenna is operating at 5.8 GHz. Each element is created with truncated-edge of rectangular shape which had an inclined slot on each patch which realize circular polarized capability. The design of the 2×1 and 2×2 of rectangular microstrip array antenna was implemented from the designed of single rectangular element of patch antenna as the basic building element. The designed 2×1 and 2×2 array were fed by microstrip transimmision line which applied a technique of quater wave impedance matching. The antenna design was etched on Rogers RT 5880 substrate which have dielectric constant of 2.2 and have a thickness of 1.53. All the designed structure were simulated in CST software. The proposed antenna finally will compared between both 2×1 and 2×2 design in terms of gain, axial ratio and reflection coefficient. The simulated antennas resonated exactly at the desired frequency of 5.8 GHz with reflection coefficient below than −10 dB which indicates good antenna designs. The 2×1 and 2×2 arrays obtained gain of 10.8 dB to 13.3 dB respectively.

This problem usually causes the efficiency of the inverter to fall to a certain level, resulting in poor inverter performance. In this study, the switching strategy can be changed to reduce the switching status while maintaining the original inverter frequency. The main goal of this research to reduce the switching loss of the inverter by modified the conventional SPWM to become a lesser switching state without losing the nature characteristic of the SPWM switching technique.

This step is called “Feature Selection”, which is considered an NP-Hard optimization problem. Cuckoo Search Algorithm (CSA) is a popular Nature-Inspired Meta-heuristic algorithm, which is used for handling continuous and discrete optimization problems. Although CSA has a great performance on many optimization problems, however, it lacks the balancing between the exploration and exploitation abilities. In this research, a binary cuckoo search algorithm with different types of crossover operators to improve is proposed. The crossover operators help the nest to discover different unexplored regions and avoid the issue of trapping in the local optima. All of the proposed versions have been applied on several datasets, and the results in terms of the classification accuracy and number of selected features were recorded. The experimental results demonstrated the effectiveness of the proposed algorithms in comparison to the original binary cuckoo search algorithm and different classifications.","PeriodicalId":337954,"journal":{"name":"2021 International Conference on Advanced Computer Applications (ACA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126984866","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}

There are four primary functions in the proposed structure: firstly, all linked camera transmissions will be received by the central server, and video signals will be shown to all attached clients and servers in Level two. The second function means that the clients/servers in level two start viewing received video signals and rebroadcasts them to the next level. The third function is clients/servers in level three who receive the video signals from the upper level and rebroadcast them to the fourth level. The fourth level consists of many clients that start viewing received video signals from level three. Therefore, the planned architecture and mechanism of the proposed system can provide the admin the capability to concentrate on the frames obtained from IP cameras to/from the central server. Furthermore, this mechanism can register and store the stream of frames and encode these frames during transmission.
