In addition to many techniques, multi-criteria decision making methods and fuzzy logic have been implemented to handle the uncertainties and assess the risks. In this study, a fuzzy MARCOS method, which is a recent multi-criteria decision making method, is applied in the road risk analysis study. Trapezoidal fuzzy numbers are adapted to express the fuzziness in linguistic expressions. 38 alternative sections are evaluated for risk according to six criteria. The results of the proposed method are compared to the results of the triangular fuzzy MARCOS method in the literature. It is observed that the eight ranks with the highest risk in the rankings of the alternatives of two fuzzy methods are preserved. It is aimed that this study increases the use of fuzzy MARCOS method in multi-criteria decision making studies.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130466809","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 is the case of tumor treatment, with special reference to organs such as liver, lung, kidney. In this case, the application of a well-localized heat source can destroy tumor cells by means of a necrotic process. Such techniques are based on different technologies: Radio Frequency and Microwave are the most common ones. Nevertheless, several open issues are still present as the optimal choice of application time, the definition of the burning area, the best stimulus signal to be applied, the modeling of the target area concerning its electric/magnetic properties whose values can evolve during treatment. For all these reasons, and not limited to, the role of engineers is crucial to obtain better performance with limited amount of energy and limited side effects for the patient. Particularly, the measurement open issues and how such issues could lead to an enhancement of the industrial production processes of needed apparatuses are reported in this paper.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132583063","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 fact, the distribution network (DN) is experiencing a significant deployment of intelligent electronic devices (IEDs) capable of enabling the monitoring and control of both the medium and low voltage sides (MV and LV) of the DN. Such a network revolution is strongly supported by the fact that renewable energy sources are spreading among the DN, introducing problems likes (i) voltage unbalance, (ii) degradation of the power quality, (iii) frequency deviations and inertia reduction, etc. In light of the above, this paper presents the design, development, and characterization of a low-cost network monitoring unit. The device, specifically developed for LV networks, has been designed according to the requirements defined by the utilities. In the paper, the design choices, the device characteristics and the metrological characterization are described. From the results it can be clearly concluded that the device may become an affordable key asset to be deployed in LV networks. In fact, it enables system operators to fully monitor, control, and promptly intervene on their networks.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130039211","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}

Consequently, the overall reliability of the railway system is reduced. In particular, the pantograph contact strips are subjected to severe abrasions during the running operations. Their maintenance and inspection are usually made manually with negative consequences in terms of costs and safety. Therefore, in the last years, no-contact monitoring and measurements techniques for the pantograph-catenary elements have been developed. A practicable methodology to measure the pantograph contact strip thickness is proposed in this paper. The employed approach is based on image processing techniques useful to detect geometrical variations of the pantograph contact strips. The no-contact measurement system is made through a cost-effective single camera. Several images of the pantograph equipped with unworn and worn contact strips are employed to verify the reliability of the proposed technique.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121691292","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 particular, reduction in hospital occupancies has been recommended in order to avoid overcrowding of the facility and prevent patients from leaving without being seen (LWBS) by medical doctors. In this context, the use of simulation models could be an effective tool to test what-if scenarios and build more robust and resilient models of healthcare processes. In this work, we take advantage of the power discrete event systems theory to design a finite-state machine for monitoring the patient flow during a generic care process and to study the LWBS phenomenon by assessing the dropout rate as a function of both the healthcare service performance and the crowding of the department. The patient's behavior and process dynamics are tested under different simulated scenarios. The proposed methodological approach could provide a generalized framework for the design of novel healthcare organizational models as well as real-time systems for monitoring crucial healthcare performance indicators, such as overcrowding and LWBS rate.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129252260","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}

Most developing countries are recording higher volumes of fatalities whenever a road accident occurs due to the lack of a proper and quick system that reports accidents to the emergency services for an immediate rescue. Moreover, the chances of survival of any casualty of an accident is mostly dependent on how quick the emergency medical services arrive at the scene and quickly reaches the nearest hospital with the victims for treatment. However, these emergency vehicles are sometimes delayed by heavy traffic en route to and from the accident scene. This paper introduces a robust automatic vehicle accident detection and alert system, which uses an accelerometer to detect the tilting and the crashing of the vehicle, sends the Global Positioning System (GPS) location of the accident scene to intended security, medical and family contacts. The proposed design achieved a turnaround response, which is faster than conventional rescue system without these features. Hence, saving more lives as possible through technology.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129600533","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, faults detection and identification is still a key challenge in LSPVI. In a large-scale photovoltaic installation, there is a large number of photovoltaic arrays. As a result of these arrays and their complex configuration, various types of faults are produced frequently which directly affect the reliability and safety of the PV installation. One of the goals of any PV installations is to retain power generation at the desired operational efficiency. To maintain the efficiency of the PV system, it is therefore important to detect defective modules promptly. In this study, a fault diagnostic technique that involves excitation of both normal and faulty modules with signals that have various frequencies is investigated. The results obtained show that the proposed techniques can diagnose and identify faulty solar panels in large-scale photovoltaic installations.","PeriodicalId":294628,"journal":{"name":"2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129716165","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}
