1 Analyzing patient health information based on IoT sensor with AI for improving patient assistance in the future direction
تجزیه و تحلیل اطلاعات سلامت بیمار مبتنی بر حسگر اینترنت اشیا با هوش مصنوعی برای بهبود کمک به بیمار در مسیر آینده-2020
Internet of Things (IoT) and Artificial Intelligence (AI) play a vital role in the upcoming years to improve the assistance systems. The IoT devices utilize several sensor devices that able to collect a large volume of data in different domains which is processed by AI techniques to make the decision about the assistance problems. Among several applications, in this work, IoT with AI is used to examine the healthcare sectors to improve patient assistance and patient care in the future direction. Traditional health care assistance system fails to predict the exact patient health information and needs which reduces the accuracy of patient assistance process. For these issues, an IoT sensor with AI is used to predict the exact patient details such as fitness tracker, medical reports, health activity, body mass, temperature, and other health care information which helps to choose the right assistance process. Healthcare mobile application is used to achieve this goal and collect the patient’s information. This information is shared in the cloud environment, which is accessed and processed by applying the optimized machine learning techniques. The gathered patient details are processed according to the iterative golden section optimized deep belief neural network (IGDBN). The introduced network examines the patient’s details from the previous health information which helps to predict the exact patient health condition in the future direction. The efficiency of IoT sensor with an AI-based health assistance prediction process is developed using MATLAB tool. Excellence is determined in terms of precision (99.87), loss error (0.045), simple matching coefficient (99.71%), Matthews correlation coefficient (99.10%) and accuracy (99.86%).

In this paper, we present necessary premises for the deployment of the Internet of Vehicles (IoV) integrating Big Data analytics of road network traffic measurements of the city of Mohammedia, Morocco. Thus, we introduce an architecture based on three main layers such as IoV, Fog Computing and Cloud Computing Layer. We specifically put more focus on Fog Computing layer in which we develop a framework for a real-time collecting and processing events generated by intelligent vehicles as well as visualizing traffic state on each road section. Furthermore, we consider deployment and test of the proposed framework using events retrieved from a Vanets-type micro simulation. Finally, we present and discuss the first obtained results as well as the advantages and limitations of the proposed architecture.

3 Privacy-aware Big Data Analytics as a service for public health policies in smart cities
تجزیه و تحلیل داده های بزرگ تجزیه و تحلیل اطلاعات خصوصی به عنوان یک سرویس برای سیاست های بهداشت عمومی در شهرهای هوشمند-2018
Smart cities make use of a variety of technologies, protocols, and devices to support and improve the quality of everyday activities of their inhabitants. An important aspect for the development of smart cities are innovative public policies, represented by requirements, actions, and plans aimed at reaching a specific goal for improving the societys welfare. With the advent of Big Data, the definition of such policies could be improved and reach an unprecedented effectiveness on several dimensions, e.g., social or economic. On the other hand, however, the safeguard of the privacy of its citizens is part of the quality of life of a smart city. In this paper, we focus on balancing quality of life and privacy protection in smart cities by providing a new Big Data-assisted public policy making process implementing privacy-by-design. The proposed approach is based on a Big Data Analytics as a Service approach, which is driven by a Privacy Compliance Assessment derived from the European Unions GDPR, and discussed in the context of a public health policy making process.

5 Destinations and crisis. Profiling tourists budget share from 2006 to 2012
مقصد و بحران سهم بودجه گردشگران را از 2006 تا 2012 اختصاص می دهد-2018
Tourist spending behavior is not only relevant in terms of volume but also in terms of trip budget composition or allocation (share or proportion of total trip budget allocated to transportation, accom modation or activities). This paper aims to profile expenditure patterns before, during and after the economic crisis, and how they affect destinations. Clustering methods and compositional data analysis is used as an appropriate statistical approach to analyze share. Incoming tourists to Spain are segmented by trip budget share using repeated cross-sections of official statistics data (2006–2012). One of the main findings is that segments are heterogeneous in their cutting back on expenditure during the economic crisis, and segments increasing in size during the crisis not only spend less but also have the lowest activity share. Furthermore, the paper identifies one of the segments being particularly attractive for destinations in terms both of total expenditure and expenditure profile, with a high activity expenditure share and usually flying with low-cost airlines. The paper contributes to understanding tourist consumer behavior in terms of expenditure pattern at micro level in times of economic recession and its im plications for particular destinations.

6 ClimateSpark: An in-memory distributed computing framework for big climate data analytics
ClimateSpark: یک چارچوب محاسباتی توزیع شده در حافظه برای تحلیل داده های آب و هوایی بزرگ-2018
The unprecedented growth of climate data creates new opportunities for climate studies, and yet big climate data pose a grand challenge to climatologists to efficiently manage and analyze big data. The complexity of climate data content and analytical algorithms increases the difficulty of implementing algorithms on high performance computing systems. This paper proposes an in-memory, distributed computing framework, ClimateSpark, to facilitate complex big data analytics and time-consuming computational tasks. Chunking data structure improves parallel I/O efficiency, while a spatiotemporal index is built for the chunks to avoid unnecessary data reading and preprocessing. An integrated, multi-dimensional, array-based data model (ClimateRDD) and ETL operations are developed to address big climate data variety by integrating the processing components of the climate data lifecycle. ClimateSpark utilizes Spark SQL and Apache Zeppelin to develop a web portal to facilitate the inter action among climatologists, climate data, analytic operations and computing resources (e.g., using SQL query and Scala/Python notebook). Experimental results show that ClimateSpark conducts different spatiotemporal data queries/analytics with high efficiency and data locality. ClimateSpark is easily adaptable to other big multiple dimensional, array-based datasets in various geoscience domains.

7 Discovering socially important locations of social media users
کشف مکان های اجتماعی مهم از کاربران رسانه های اجتماعی-2017
Socially important locations are places that are frequently visited by social media users in their social media life. Discovering socially interesting, popular or important locations from a location based social network has recently become important for recommender systems, targeted advertisement applications, and urban planning, etc. However, discovering socially important locations from a social network is chal lenging due to the data size and variety, spatial and temporal dimensions of the datasets, the need for developing computationally efficient approaches, and the difficulty of modeling human behavior. In the literature, several studies are conducted for discovering socially important locations. However, majority of these studies focused on discovering locations without considering historical data of social media users. They focused on analysis of data of social groups without considering each user’s preferences in these groups. In this study, we proposed a method and interest measures to discover socially important loca tions that consider historical user data and each user’s (individual’s) preferences. The proposed algorithm was compared with a naïve alternative using real-life Twitter dataset. The results showed that the pro posed algorithm outperforms the naïve alternative.

8 Pervasive social networking forensics_ Intelligence and evidence from mobile device extracts
اطلاعات جغرافیایی پزشکی قانونی شبکه های اجتماعی فراگیر : اطلاعات و شواهد از عصاره دستگاه های سیار-2017
In pervasive social networking forensics, mobile devices (e.g. mobile phones) are a typical source of evidence. For example, figures from an Australian law enforcement agency show the number of mobile phones submitted for analysis increasing at an average of 60% per annum since 2006, and data from FBI regional computer forensics laboratory showing an increase of 67% per annum for mobile phone examinations. When coupled with the growth in capacity of memory card and device storage, which doubles approximately every 15 months, there is an ongoing and increasing growth in the volume of data available for evidence and intelligence analysis. There is a potential for information relevant to a range of crimes within the extracted data, such as terrorism and organised crime investigations, with potential cross-device and cross-case linkages. In this paper, we propose the Digital Forensic Intelligence Analysis Cycle (DFIAC). Using mobile device extracts from an Australian law enforcement agency, we demonstrate the utility of DFIAC in locating information across an increasing volume of forensically extracted data from mobile devices, and a greater understanding of the developing trends in relation to mobile device forensic analysis.
