The IoT technology is closely related to other emergent technologies such as cloud and fog computing, which provide virtualization services and mobile facilities. For that reason, the development of correct fog/IoT environments contributes to the IoT technology deployment where one of the most important aspects in the cloud/fog/IoT computing is the service mobility between fog and cloud levels. In this paper, we analyse the communication specification of a scenario composed of mobile IoT devices in a fog and cloud computing system. The devices movement implies the migration of their virtualised services along the fog or cloud system. Our system specification is based on Algebra of Communicating Processes. The system behaviour has been specified through formal algebraic rules which are rooted branching bisimilar.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130651909","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}

Increased corona discharge losses may be one of the indicators of temporary short circuit faults in the power line or damage of power line insulation. Also, this type of discharge is the source of higher current harmonics, which can adversely affect the reliability of communication and other technical systems in the vicinity of the power line. The characteristic of the corona discharge in the line is influenced by the surface crack or break-down of the insulators in the garland, damages in the wires structure, approaching tree branches and various atmospheric phenomena. The identification of the causes of corona discharge is an important task in reducing the technical costs of energy transmission and increasing the reliability of power lines and other technical systems in their vicinity. The paper presents the results of the research aimed at examining the possibility of determining the causes of corona discharge by analysing the current and voltage registrations from fault identification and location system.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115997522","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}

However, communication protocols based on a central entity called broker fulfill those requirements, since they help end devices to offload their tasks, thus improving the overall system performance. Among those IoT-based protocols, MQTT is one of the preferred choices, as being lightweight, bandwidth-efficient, low-energy consuming and capable of offering reliable messaging. In this paper, MQTT is selected in order to perform a study on its behavior by means of a simplified model built by using an abstract algebra called Algebra of Communicating Processes (ACP). In this context, first, the entities taking part are modeled, then, specification is carried out, and finally, verification is undertaken, showing that the model proposed meets the requirements expected for MQTT.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116601596","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 specifics of this solution is related to possibility of very wide input voltage supply (1-phase/3-phase AC or 120–650 Vdc) together with symmetrical outputs supplying auxiliary circuits of main power stage. The main outcome of paper is design proposal on main circuit of auxiliary supply (AUX) as well as on control and driving sub circuits. Control and driving parts have been analysed more in detail due to arise of voltage imbalance on power transistors during operation under high input voltage. This imbalance is caused by the topology itself because of different emitter potentials and thus dynamics that is related to Miller effect. Within this paper the solution how to overcome this deficiency is based on tuning the values of gate resistances on power MOSFETs. The procedure is verified by experimental testing. At the end, the performance of AUX is verified for full operation range.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127610266","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}

During the research, the several tests have been conducted for both types of sensors and the data obtained has been summarized in form of multiple charts. All tests were aimed to be as close to field environments, as it is possible to achieve, so that sensor behaviour could be evaluated in situations the average user can face while using stabilizing gimbal.

Compared with traditional qZSI, the boost ability of the presented circuit is increased. Furthermore, the total harmonic distortion (THD) for the voltage and current at the output is reduced because of a modified unipolar pulse width modulation (PWM) technique adapted for the qZSI. Therefore, the overall efficiency of the circuit is improved. The operation principle of the single phase modified qZSI is analysed using theoretical calculations. Simulations are performed to prove the effectiveness of the high boost voltage conversion ability for different modulation indexes using Matlab/Simulink. The applied modulation technique is compared with the traditional PWM control techniques to show reduced THD value which is very close to the IEEE distortion limit. A laboratory prototype is developed to validate the proposed theory.","PeriodicalId":186085,"journal":{"name":"2020 24th International Conference Electronics","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129545966","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}
