Cloud Technologies in Focus of Redesigning Medical Devices for Patients’ Convenience and Data Safety

Sara GRAČIĆ, Zoran ĆIRIĆ

Cloud technologies have an immense potential in medicine, because they enable patients to (pro)actively take part in their healthcare management and partner up with their doctors. This partnership can be seen in the usage of various medical apps for monitoring vital signs, tracking diet and exercises, as well as on a more serious note – using medical devices with or without instructions of their doctors. Although this brings benefits, it also has a downside. Not all apps are reliable, not all medical devices are as safe as supposed. In emergency, medical data can be easily obtained by entering visible PIN code. How safe are medical data if someone decides to misuse them? To answer our doubts, we have researched relevant websites and scientific papers and proposed changes in one medical device and completely redesigned the procedure of accessing someone’s medical records to ensure their safety.

Computer-Assisted Translation in Teaching ESP

Darko KOVAČEVIĆ

Computer-assisted translation (CAT) is the translation from one language into another where a translator uses computer software as an aid in the translation process. Besides the general word processing software, which provides certain tools for facilitating the work on translation, and different online and offline tools, there are specific, dedicated pieces of software intended exclusively for this purpose, which resolve the text into smaller, translatable segments, and organise them in a manner which makes it easier for the translator to translate the text effectively. In the first part of the paper, after a generalised introduction, the main features of CAT will be discussed, as well as wider and narrower aspects of CAT. After that, the using CAT in teaching ESP will be discussed, with special emphasis on the combining of different software and tools to be used in the translation process and on the set of actions to be performed in these lessons.

Designing the Distance Measurement System for a Mobile Robot

Duško LUKAČ

The paper presents the electronic design of the sensor control circuit for existing mobile platform with articulated robot. Sensor control unit, compatible to the existing electronic layout, is developed to create the necessary conditions for the autonomy of the mobile platform relating to its mobility. With the sensor equipped platform, inter alia, the problem of self-localization can be tackled and solved. In particular the sensor type and the electronic circuits are exemplified which are used in the application. Additional, the sensor principles, the electronic subsequent treatment procedure of the sensor signals, their provision for the connected bus system as well as the special programming requirements are explained. Concluding, the experimental results and the experiences which are won with the present test construction are highlighted.

eNodeB Power Saving in LTE Network

Milan LUKIĆ

Nowadays it has become very important to preserve the environment. By reducing power consumption of the eNodeB it possible to minimize negative impact on environment. On the other side, one of the main target of the telco operators is to decrease operational expenses. Mobile vendors have introduced new features that are allowing to achieve both of the mentioned goals. In this paper, two features will be presented and their functionalities will be closer described. BTS Embedded Power Meter for Energy Efficiency Monitoring feature is necessary to activate in order to measure power consumption of eNodeB. After the activation of the mentioned feature and power consumption measurements have been collected, another feature is introduced. eNodeB Power Saving MicroDTX feature provides energy saving of the eNB. It is obtained by switching off the cell’s power amplifier (PA) for the duration of unused orthogonal frequency-division multiplexing (OFDM) symbols. In the final part of the paper influence of the features on the major LTE KPIs is presented, as well as achieved power consumption reduction.

Exploring the Performance of LoRaTM Modules for Indoor Based Wireless Sensor Networks

Dalibor DOBRILOVIĆ, Željko STOJANOV, Milan MALIĆ, Dušan MALIĆ

This paper is focused on LoRa technology and analyses of its performance as technology for indoor environments. LoRaTM made appearance as a Low-Power Wide Area Network (LPWAN) technology with the appliance in wide area environments such as Smart Cities and Smart Transportation. Those applications are designed for outdoor areas, where two main LoRaTM advantages (long range and small energy cons1umption) are very favorable. Recently, authors have started to explore LoRa technology performances in indoor environments. Other characteristics of these researches are extensive usage of open-source hardware based platforms, such as Arduino, in design of devices for testing and evaluation. In this paper is presented the prototyping platform based on open-source hardware and low-cost components for testing LoRaTM in indoor environments.
