This work focuses on the parameterization and evaluation of predictive algorithms utilizing metered data on predefined time intervals. More specifically, electricity consumption as a total, but also as main usages/spaces breakdown and weather data are used to develop, train and test predictive models. A technical comparison between different classification algorithms and methodologies are provided. Several weather metrics, such as temperature and humidity are exploited, along with explanatory past consuming variables. The target variable is binary and expresses the volume of consumption regarding each individual residence. The analysis is conducted for two different time intervals during a day, and the outcomes showcase the necessity of weather data for predicting residential electrical consumption. The results also indicate that the size of dwellings affects the accuracy of model.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116200458","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}

First, the Haar cascade classifier was used to find candidate regions. Then, a DoG filter was used to detect the edges and connected component labeling was applied to obtain the candidate blocks. The license plate color characteristics were used to eliminate irrelevant blocks using histogram comparison and color quantization. The Bhattacharyya distance and the correlation metric were used to compare the histograms. Experiments with real data showed good performance. The dataset consists of various road and weather conditions including expressway, downtown, sunny days and rainy days. For our dataset, the recall was 0.72, the precision was 0.88 and the F-score was 0.79. For the Caltech dataset, the recall was 0.86, the precision was 0.96 and the F-score was 0.91.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116677168","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}

Our solution is founded on motion sensors and smartphones, hence, it is affordable and easy to deploy in real scenarios.

Recently, there has been an increasing demand for digital learning based on mobile devices, namely m-Learning. The development of an effective mobile authoring tool which provides the ability to instructors to manage the learning content with the intention not only to facilitate the content delivery, but also to improve the learning process by adapting content to students’ needs, is a critical task. To this direction, this paper presents the development of a novel mobile content authoring tool which incorporated dynamic reports on refining teaching strategies according to Learning Analytics; i.e. the analysis of the large amount of information resulting from the interaction of students with the m-learning app. The goal of this authoring tool is to support an m-learning system and help teachers to improve their instruction through personalized suggestions on the design and revision of the provided learning content. The developed authoring tool was used by teachers in secondary schools and was evaluated by them. The results of the evaluation showed that the incorporation of Learning Analytics is indeed considered as useful for the tutors supporting them through efficient authoring tools in m-learning environments.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128927547","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 work we present taxonomy of mobile health applications. In this paper we consider health and medical mobile applications as equal. This categorization intends to provide an approach to organize the view of the work that has been carried out in the area of mobile applications in the healthcare domain. Furthermore, the objective is to distinguish the applications according to their target user groups The top apps were organized into groups, based on their usage, user satisfaction and end-users. It is apparent that m-health apps still have plenty of room to grow, towards taking advantage of as many advances as possible, from all the available unique mobile platforms’ features.

To address this problem we developed a prototype algorithm that is a hybrid form of the Particle Swarm Optimization (PSO) algorithm. The original PSO algorithm simulates the mode of a bird cluster movement into nature. In particular, as in this case the solution to a problem with discrete values is needed, we developed a hybrid form of this algorithm with local search, in the process of which we incorporated original methods. The main contribution of this paper is how to improve particles based on optimal Gbest (Global best) and Pbest (Particle best) values of the particles. Our work provides also a fully detailed description of the innovate solution on how to update the algorithm particles in each iteration of the optimization process (Local Search). Our algorithm achieves satisfactory results within seconds.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116031933","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}

Technology can facilitate their engagement by making resources and support available in order adults to have access when and where they have time. Technology provides the possibility of including multimedia and interactive resources that can make adult learning more attractive and realistic, encouraging and even inspiring adults to develop their skills. Moreover, it is essential the online environment to follow the principles of adult education. SN-Learning is a new technology advancement that employs social networks for promoting learning. This technology has not been widely used in adult education yet. To this direction, this paper analyzes the main adult learning theory, namely Andragogy, and its application into SN-Learning in order to promote high-quality adult online education tailored to the needs and preferences of this kind of learners. A prototype system was developed and evaluated regarding students’ perspective and system’s specification.
