401. Evaluation of Neural Networks Based Systems for DNA Motif Discovery

ICIST 2018 Proceedings Vol.1, 232-236
Mišić Milena, Stanimirović Aleksandar, Stoimenov Leonid
Abstract: The main goal of genome analysis and DNA motif finding is to explain cell mechanisms and their influence on genetic diseases. The technological advances in the area result in large amount of data that needs to be processed in order to solve these challenges. That is why machine learning is becoming popular for genome analysis and motif discovery in particular. Some example systems that implement machine learning techniques are DeepBind, DeeperBind and DeepMotif. This work’s primary objective is to assess the performance of these systems, examine their usability and behavior on new datasets and provide insights as to what causes the errors systems make. Previous evaluations are available, but do not incorporate neural network systems which are known to achieve the state-of-the-art in other areas. This research aims to address this issue and uses more common systems (e.g. Gibbs Sampler or implementations of the Expectation Maximization algorithm) to establish a baseline.

Nazarenko Artem, Sarraipa Joao, Figueiras Paulo, Costa Ruben, Jardim-Goncalves Ricardo
Abstract: General understanding of possible benefits achieved through implementation of industrial Internet of Things (IoT) solutions, set a clear need to develop new approaches to manage and orchestrate distributed and heterogeneous data and components within an IoT environment. Vf-OS initiative provides FIWARE enabled solutions with focus on the manufacturing domain. The challenge to be addressed here, is on how to instantiate the vf-OS concept to other relevant domain sectors, as the mobility and transportation, in order to provide a full-fledged FIWARE functionality based on Generic Enablers, by reusing and proposing new ones.

404. IoT for active and secure aging with Alzheimer

ICIST 2018 Proceedings Vol.1, 247-250
Luís-Ferreira Fernando, Sarraipa Joao, McManus Gary, Zdravković Milan
Abstract: The expectancy of live has been extended in modern societies becoming a symbol of civilizational progress, with technology supporting medical research and healthcare improvements. In technological domain, diagnosis and monitoring benefit from data collection from the most diverse sources. Along with specific medical equipment, data sources are available in what is becoming a sensor rich environment. The concept of Internet of Things refers to the sensing and communication devices that are becoming pervasive in modern societies. The present work proposes the usage of multiple data sources to support reasoning and decision for people with aging associated health conditions. Beyond ensuring safety and risk avoidance it is aimed to support active aging while stimulating healthy behaviors and social inclusion. The proposed architecture focus on monitoring and reasoning over available data sources to ensure risk assessment and adequate response to health risks internal or in the environment. Beyond risk it is aimed to promote active living, good habits and socialization thus ensuring active aging in daily routines, leisure and work. The proposed framework deploys a coach, or a companion that is always present and manifest only when needed. The decision process reasons based on clinical directives and situation awareness to determine risky situations for a citizen with cognitive vulnerabilities and react according to such reasoning promoting safety for elder citizens and comfort for carers and family thus supporting active and healthy aging for the target population.

409. Interoperability for the sustainability assessment framework in IoT like environments

ICIST 2018 Proceedings Vol.1, 21-27
Timčenko Valentina, Zogović Nikola, Đorđević Borislav
Abstract: Internet of Things (IoT) as a concept provides a possibility of interconnecting different devices and technologies through the Internet. Such diversity of devices and heterogeneity of the communication protocols, data formats and service demands for storage, energy, and availability has imposed a huge set of side effect issues that are becoming the serious stumbling stone in IoT-like system design and management. In this paper we have put interoperability in the center of our attention as one of the most persistent issues, making an effort to enhance the multi-objective cloud computing sustainability assessment framework by providing the necessary level of sustainable interoperability for IoT environments.

411. Detection-Response Task: How intrusive is it?

ICIST 2018 Proceedings Vol.1, 1-5
Stojmenova Kristina, Sodnik Jaka
Abstract: The Detection-response task (DRT) is a method for assessing the attentional effects of cognitive load of drivers. Although many studies focusing on the evaluation and the sensitivity of the method have been performed, it is harder to find data on the impact of the method to the driver and his/her driving performance. In this paper, we present a study in which we explore the intrusiveness of the method of all of its versions: visual DRT, tactile DRT, and auditory DRT. We explore possible effects on cognitive distraction, driving performance and secondary task performance (for example operating an in-vehicle device). The results got in the study suggest that DRT does not impose significant additional cognitive load, however it affects driver speed regulations in terms of acceleration deviations, and increases the time need to complete secondary tasks.
Abstract: In this paper will be presented the solution of achieving interoperability between enterprises that together design the software, or one enterprise wants to integrate their software module with software of other enterprise. The idea for this research has appeared after analyzing Conway’s law and Functional Silos. Organizations should put more efforts on communication between people/teams in organizational structure. It is not enough for organization to share knowledge only on vertical axis, the communication on horizontal axis gives more opportunity for achieving common goals of enterprise. While analyzing the Conway’s law and Functional Silos, have think about the solution for achieving interoperability between heterogeneous traffic management software’s which are product of two different companies. The problem of interoperability of this research is when two enterprises want to integrate them software’s. But on one side we have enterprise which have “old fashion” traffic management software based on old software architecture, and on the other side is enterprise which have the traffic management software with new generation of software architecture. The goal is that traffic management system from enterprise 2 communicate and processed data from traffic controllers (devices) from the system of enterprise 1.
Abstract: In this paper we present the novel approach to the application-inspired learning, by introducing GeoGebra as an information technology tool for mathematical education of students of electrical engineering and computer science.

414. A conceptual framework for verification of complex system simulations

ICIST 2018 Proceedings Vol.2, 265-267
Dimitrijević Sandrina
Abstract: While process of verification of traditional simulation models is well established, fresh approaches are needed for new types of simulation. That is especially the case for simulation of complex systems which have unique properties (emergent behavior, high sensitivity to changes) that can mask faults in code and wrong design. In this paper we deal with such challenge by proposing a conceptual model for verification of complex system simulation. Namely, we suggest that each verification attempt needs to include usage of individual elements checking along with top-down approach to system testing.

415. Use of ITIL

ICIST 2018 Proceedings Vol.2, 268-273
Paroški Milan, Mihajlović Milan
Abstract: This paper compares the ITIL with other most familiar methodologies for managing IT services. I carried out a SWOT analysis of the application of ITIL and described additional ITIL research in the sectoral areas. I explained why organizations use ITIL and performed an analysis of using ITIL in teaching in Serbia. I further explained I described the most popular examples of developing own ITIL as well as the best practice in applying ITIL in state-owned organizations. My motivation for researching the application of ITIL lies in looking at the broader aspects of using ITIL as an ITIL lecturer at FTN. The goal of all these analyzes was not to get into the ITIL's guidelines and content, but to investigate and demonstrate in one place all the applications, benefits, possible upgrades of ITIL, and the use of ITIL in theory and practice.

417. Model-based, client-side integration of heterogeneous data from REST services

ICIST 2018 Proceedings Vol.2, 278-281
Zdravković Milan, Vitković Nikola, Trajanović Miroslav, Trifunović Milan, Korunović Nikola
Abstract: With the increasing implementation of Internet-of-Things paradigm, the increase of data volume and diversity threatens to diminish the potentially valuable effects of their reuse in multiple circumstances. While increasing number of datasets, coming from devices or elsewhere is being exposed by using APIs, very few of them is based on the standard dictionaries, data structures and models. For that reason, it becomes very difficult to integrate data of similar or identical semantics, coming from different sources. In this paper, we propose the meta-model for client-side application which aggregates semantically identical or similar data from multiple REST APIs in a single Angular-based widget. Main concepts of the proposed meta-model are data objects, services with defined object and property mappings, use cases and user interface components. Model is implemented in the data integration platform and it is validated in the case of searching data about research projects from two sources. The search widget is implemented on the EURAXESS portals.

420. Adaptation of HTTP request-response messaging to arbitrary messaging pattern in RESTful service oriented architectures

ICIST 2018 Proceedings Vol.2, 290-295
Nikolić Lazar, Letić Marko, Zoranović Bojana, Dejanović Igor
Abstract: Service oriented architectures have traditionally been using HTTP messages for client-server communication, as well as inter-service communication. However, request-response pattern of HTTP protocol can be inefficient for messaging patterns such as event-driven messaging. The problem arises for architectures that need to introduce new messaging patterns, but already use HTTP. In this paper we present architecture of an adapter that converts HTTP messages into messages of another protocol. Such protocol can use a messaging pattern other than request-response. We cover synchronous request-response, asynchronous request-response and event-driven messaging patterns. The adapter must also allow transition to a new protocol or messaging pattern without affecting service interface definitions and their application logic. We also present an implementation of such architecture and discuss the results.
