Given documented discrepancies between the design and operation of buildings, concepts such as continuous commissioning and performance testing (PTing) have emerged. To increase the applicability and customizability of real-time performance monitoring, PTing frameworks utilize metadata schemas and generic libraries of tests. However, real-time PTing requires enhanced instrumentation in the building, such as meters and sensors. Considering the usage and age of buildings, different buildings impose more stringent requirements for sensing equipment in terms of applicability of PTing. Prior work establishes a framework for automatic discovery of performance tests, and their continuous execution without human intervention. In this paper, we provide an algorithm for automatic estimation of the Smart Readiness Indicator (SRI), a metric for measuring the technological readiness of a building proposed by the European Commission. In line with our PTing framework, we estimate a minimal SRI for PTing to be 23%, implying high applicability across a variety of buildings. We evaluate a case study building for its SRI and perform sensitivity analyses of the SRI specific requirements against the PT-SRI.","PeriodicalId":223539,"journal":{"name":"2019 4th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133756058","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}

Previously, the stray load loss impact has been examined only for induction motors. Detuning in vector-controlled induction machines (IMs) is caused by a mismatch between the actual IM and the corresponding mathematical model. This usually implies disagreement between the actual and assumed values of IM parameters or between the actual and modeled phenomena. The detuning is characterized by a misalignment between the actual and reference flux vector (i.e., flux angle error) or by a non-unity ratio of actual to reference flux vector magnitudes (i.e., flux magnitude error). The presented analysis encompasses load torques up to the rated value and rotor flux values down to 50% of the rated value. For this purpose, an IM model is utilized in which the stray load and iron losses are modeled as variable with respect to the operating frequency, flux, and torque. The simulation model of the considered system is built in the MATLAB-Simulink. Three small IMs (1.5 kW) of different efficiency and rotor material have been considered.","PeriodicalId":223539,"journal":{"name":"2019 4th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134405783","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 operational analysis of BIPV system and energy storage with contribution to local load profile is needed for its grid connected operation, as well as for integrating it in the micro-grid system. In this work, a typical institution has been selected, where the PV system and energy storage are operated for supplying local load in coordination with the grid. The institutional load profile has been analyzed with essential and non-essential loads for understanding the operation and contributions from the PV and battery energy storage in addition from the grid. Annual institutional load variations and PV system outputs are analyzed for evaluating the installed battery’s energy throughput and energy contents. Two typical scenarios, with worst and best cases, are used for performance assessment of the considered energy system. It is observed that essential loads are fulfilled during the grid outage through batteries, but load reliability has significant impact if the grid outage is longer. It is noticed that the battery energy throughput must be maximized for effective PV output utilization to fulfil local demand. Results from this work are going to contribute for developing an institutional micro-grid with appropriate sizing of distributed generator as well as on demand side management with grid constraints.","PeriodicalId":223539,"journal":{"name":"2019 4th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123404542","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 several challenges associated with the care of epileptic patients, including: 1) the timely and accurate diagnosis of the condition; 2) the long-term non-intrusive monitoring and detection of epileptic seizures in real time for suitable interventions; 3) alleviating the mental health issues associated with epilepsy, such as anxiety and depression; and 4) the lack of availability of large scale datasets related to epileptic patients with different profiles, needed to advance research in epilepsy. In this work, we propose EpiSense – a smart healthcare solution for epileptic patients’ care. EpiSense leverages sensory, mobile, and web technologies, as well as machine learning techniques for the real-time detection of epileptic seizures. As part of the system, a patient’s mobile app. is provided to allow the detection of seizures’ occurrence in real time and the sending of alarm notifications to care takers, for appropriate actions. Moreover, a web portal enables doctors to view the progress of their patients and get notified about seizures’ occurrence and statistics. The EpiSense system was designed and implemented, and three machine learning models were tested for real-time epileptic seizure detection. This work gives interesting insights about the possibility of using sensory technologies and data analytics for the improvement of epileptic patients’ care, and offers the possibility of personalized healthcare management.","PeriodicalId":223539,"journal":{"name":"2019 4th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130015884","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}
