Many advances in pacemaker control technology have been achieved, making today's pacemakers capable of correcting many electrical heart abnormalities. In this paper, a fuzzy model reference learning control was designed to control the pacemaker, and compared with a controller adopts the adaptive mechanism instead of the learning mechanism, in order to confirm the importance of learning in the controller.  The controller automatically controls the heart rate (Heart Rate: HR) to prevent it from falling under a reference value and makes it track preset signal accurately.

We must therefore think of making use these huge reserves interested in desalination techniques. The stain majored is therefore to achieve a distiller solar plan which meets these needs in drinking water. The absorber surface of the modified solar still is coated with black enamel paint and covered with copper chips. The evaporation rate of the water in the solar still is directly proportional to the exposure area of the water. Thus the productivity of the solar still increases with the free surface area of the water in the basin. The distillate yield was found to have improved considerably, especially when the water depth was high. The study also indicated some design features that would further enhance the improvement in output due to the modification made, the evaporation rate is proportional to the temperature of the free surface area of the water only. A general model based on heat transfer balances in each component of the system was developed to predict the mass of freshwater. The efficiency of this still was about 65% and can produce about 5.13 l/m2 per day, experimental studies and the outcomes are discussed in the article. We propose a new design of the cascading solar desalination still with obstacles and preheating of inlet water.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84249300","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}

So the question is how to prepare students to join the industry?

In the academic sector in particular, the field training is one of the core courses that students must enroll during the third and fourth academic year, where the students have manually to select a relevant organization or institution based on their specialization. The academic staff and hosting institutions do not supervise the trainees as required due to lack of communication between them, wrong selection of the hosting institutions by students in some cases, limited following-up the trainees, thus leading to uncertainty in the number of training hours and reports required by students. These problems can be addressed or mitigated by proposing an electronic training system improving the communication between supervisors of field training, host institutions, and trainees and thus solving most of the mentioned problems. Based on this e-training system, the training unit at the university could therefore follow-up the trainees and thus improve the communication and cooperation with the training institutions. It will also definitely contribute in improving the training task itself for the students. In this proposed paper, the importance of the proposed system was presented. Other related systems were mentioned and used as references in the analysis stage. In the analytical stage, data was collected using 3 different questionnaires developed for students, supervising staff, and for the training institutions. Consequently, obstacles and problems faced these entities were extracted and mentioned. Finally, a preliminary design was proposed in this paper to develop and implement an electronic training system at Palestine Ahliya University.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84897115","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 objective of this study to classification ADLs according to their domain, domain specific or general purpose languages, doing these systematic literature review flowing the steps from Ketchenham. As the result we find that most ADLs are Domain Specific ADLs (Aviation Systems, Distribution Systems, Mobile Systems, Product Lines …etc. ) none of these ADLs is used in the field of software architecture education, but most intended to deal with experts in the field, except general purpose ADLs, like ACME, which we make as start point to design Arabic ADL, so as to enrich Arabic content, also to be as helping language in teaching Software Architecture course, because most of ADLs need experience and high level of understanding to use, moreover, when student think and design with same language subject more understandable. So using software architecture description languages in educating purpose, help on understanding high level of abstraction of software architecture and software engineering courses, there are some studies that aimed to reduce the complexity of these courses using different methodologies and approaches, but none of them using architecture description languages as helping tool. So the use of architecture description languages is helpful in teaching software architecture and software engineering courses.  ","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84799316","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}

We are witnessing an increasingly widespread use of pub/ sub for a wide array of applications in industry, academia, financial data dissemination, business process management and does not end in social networking sites which takes a large area of user interests and used network bandwidth. Social network interactions have grown exponentially in recent years to the order of billions of notifications generated by millions of users every day. So, it has become very important to access in the field of publishing and subscription networks, especially peer-to-peer (P2P) networks in many ways like the publication speed for events And the percentage of loss in the incoming events of the participants. Peer-to-peer systems can be very large and include millions of nodes, those nodes join and leave the network continuously, and these characteristics are difficult to handle. The evaluation of a new protocol in a real environment, particularly in the early stages, was considered impractical. Hence the need for a simulator to perform such a function to facilitate the simulation of researchers and this emulator is an open source simulator running within the Eclipse environment. In this research we have adopted a new method of selecting nodes within the table of vicinity protocol. This method is concentrated in that the far node increases the probability of its inclusion in the table more than the adjacent node. and The proposed network that uses the Polder Cast protocol was modelled using PeerSim software for modelling deployment and subscription networks within the eclipse environment so that the event delivery service is a Peer-2-Peer network and the method used to register is subject-based (Topic-Based). experimental results showed noticeable improvement in the publication speed for events by 51.11% compared to the original design of the protocol. And The percentage of event loss was reduced by 20%.    ","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88429528","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}
