Smart Work Order 
Smart work order (SWO) is a technology-driven approach that utilizes augmented reality (AR) smart glasses and knowledge management data base (KMDB) to improve field services (FS). A work order (WO) is a specific job, repair, or any other FS team’s physical activity. SWO leverages identified opportunities for automating operations in the field. It makes use of machine learning and artificial intelligence (ML/AI) processes to access knowledge captured in KMDB and generates options for improved hardware repair, installation management, or predictive maintenance. Consequently, the efficiency and sustainability of field services and work orders are raised due to shorter time to deliver, lower travelling costs and less rework required. SWO developed in Ericsson Nikola Tesla Group (ENTG) is configured by augmented reality technology, and machine learning algorithms supported by ITILv4 best practice framework where each SWO part creates added value in the field services chain. Additional integration with operations wisdom logging (OWL) toolset empowers FS team members with advanced knowledge in daily work. All SWO parts can access real-time data which enables FS teams to utilize knowledge management systems to determine first-time right actions. SWO automatically generates all required steps which walk FS teams through required actions, from capturing an alarm, over identifying the problem, finding a solution, and visualizing required actions to confirming the problem has been cleared up.

Bringing Children Closer to Science and the Universe with New Technology
In the era of technology and social networks, it is difficult to attract children to science. To change this, three applications have been developed whose primary goal is not pure entertainment, but to educate and encourage scientific exploration in children. These applications were developed using new technologies, i.e. augmented reality, virtual reality and Ultraleap. Each application brings the intrigue of the universe to children in an interesting way by providing them with age-appropriate content and information about the universe. In these applications, interactive space travels can be taken to learn about the sun and planets, and fun games can be played to stimulate interest in further observations and knowledge about the universe. The paper describes the applications and the multidisciplinary context of their development, as well as the potential of the new technologies in education.

RFID Inventory Management System Sampling Optimization Based on Zebra Android Framework
In services with high rate of input and ouput of items, inventory data collection process often sets high demands on staff in terms of reliable evidenting and overall repeatability. Some business services, like on-site laundry facilities in public hospitals, offer a good platform for ad-hoc implementation of custom ICT inventory management solutions, especially if they already have partially implemented some kind of proven technologies, such as RFID. If taken in account relatively low cost and ease of design, development and implementation of such systems in public or other institutions and industry segments where accurate and reliable daily based item inventory is crucial, then it undoubtedly offers good alternative to commercially available inventory management systems. Data element processing operations are an indispensable part of any information system. The above operations are optimized with an emphasis on speed and reliability of execution to meet the timing requirements of RFID sampling. This includes improvements to the database scheme, as well as the application and adaptation of existing algorithms for retrieving duplicate elements of data sets.

Study of Data Transfer Nodes Infrastructure in Enabling Big Data Movement between Research and Cloud Storage Networks
Data research projects generate huge amounts of data, which are usually stored in cloud networks for processing and storage. Transferring large amounts of data between multiple research sites, often within protected scientific DMZs (Demilitarized Zone) and cloud storage nodes, requires high-speed network connections.
To ensure efficient data transfer and processing, parallel data streams are used between multiple research sites, with dedicated cloud infrastructure for processing and storage of a particular experiment. Since multiple nodes or sites are involved in data transfer, DTNs (Data Transfer Nodes) are used to solve the problems of fast data flow and performance between nodes that are not related to network throughput. DTNs include software transfer tools and high-end hardware components that are tasked with preparing data for transfer.
Several research groups are working to establish multiple DTN instances as part of a large-scale scientific data network. This paper provides a brief overview of the current state of the art in the use of DTN infrastructure and the challenges associated with preparing data for transfer.

PAPA for IoT - Role of Data Accuracy in IoT Deployment and Data-centric Decision-Making
Data has become a central asset supporting decision-making in modern business environments. Internet of Things (IoT) solutions in particular are designed to gather information from a large variety of monitorable entities, providing companies with seemingly unlimited abilities to measure and analyze factors such as performance and productivity.
Considering the reliability and trustworthiness in data-driven decision-making, the accuracy of the leveraged information is critical. While the development of IoT solutions makes them continuously more accurate, caution must be applied not only in terms of potential inaccuracy caused by technical failures but also by human error. Thus, some of the key questions to consider when investigating the accuracy and trustworthiness of data are: is the gathered information itself correct, is the leveraged data contextually correct, and what are the potential issues caused by human error.
From an ethical perspective, the justifiability of leveraging potentially incorrect data needs to be addressed. When decisions related to individual employees are being made based on data, it is necessary to not only consider the possible inaccuracy of the data but also to prevent manipulating or distorting the results by applying too limited or falsely selected data, creating a biased basis for analysis and decisions.

User Input Search – Custom Motion Estimation Algorithm Optimized for UAVs
Unmanned aerial vehicle technology is growing rapidly as it finds its application in the various industries, including military & defense, agriculture, logistics, transportation, healthcare, entertainment and many others. One of the fastest growing industries including drones is the entertainment industry. More specifically, First Person View (FPV) piloting has become a popular sport which attracts huge masses. In FPV systems, the pilot wears FPV goggles and controls the drone using a controller, and the drone transmits video data to the goggles in real time. Since drones usually fly very quickly, the video quality in terms of resolution, compression artefacts and end-to-end delay must be maintained.
This paper explores the idea of optimizing the motion estimation algorithm of existing HEVC algorithms by utilizing user input from the controller in FPV systems. For example, if the drone is directed to hover to the left, then it would make sense to search for the most similar blocks in the next video frame only on the right side of the reference block. For the purpose of this research, a HEVC video coder was customized to receive additional input besides the video data – the user input from the controller, or in other words, drone movement directions. We call this ME (Motion Estimation) algorithm UIS (User Input Search). Our UIS algorithm is compared with the standard ME algorithms and its efficiency is tested.

FOGO - An Optimized Fog and Edge Computing Method for VANETs
For mobile systems to become more effective, user-friendly, and autonomous in the future, massive data and quick information processing are essential. Future mobile systems' main challenge is data collection and processing, and in this study, we suggested FOGO, a practical approach that makes use of fog and edge computing concepts. The method suggests making use of an enhanced current infrastructure in which additional mobile fog nodes are added to the network together with the existing stationary nodes. Mobile fog nodes handle short and medium-length messages, process them, and then distribute the results throughout the network. Roadside units (RSUs) are fixed, high-performance hardware equipped, and strategically positioned units that are positioned around the network to assist the processing of increasing volumes of data. Additionally, the cloud is taken into account, but only when processing large amounts of data. Along with the presented method flowcharts, operating algorithms, and message structure, the proposed system architecture is described. Furthermore, potential use cases are suggested together with the metrics for the system performance evaluation. The new architecture was evaluated using the LuST scenario, and the findings revealed increased message processing effectiveness.

On Signal Attenuation in 5G Higher Frequencies Transmissions with Different Area Scenario
Energy and cost efficiency are becoming criteria of increasing importance in the design of 5G radio relay lines, especially for areas close to water surfaces, where there is pronounced fading, which is characteristic of radio relay paths that pass on the surface of the water. In this paper, the research was carried out on two radio relay links with different frequencies – the first one at 8 GHz, and the second at 18 GHz, working in frequency diversity mode. To troubleshoot, the measurements were made during the shortest possible time, with fixed emissions to account any fluctuations in signal levels.

Outage Probability Determining for Wireless Systems in the Presence of Beaulieu-Xie Fading and Co-channel Interference Rayleigh Modeled
For realistic assessment of any wireless communication system performance an accurate modeling of this system is necessary. Till now, no many distributions were found to be able to characterize a channel with both, the line of sight (LOS) and the non-LOS (NLOS) components. One of such distribution unifying the non-central chi, generalized Rician and κ – μ distributions into a single fading distribution is Beaulieu-Xie distribution. Beaulieu-Xie fading, as disturbance in wireless system, will be considered in this work. Beside fading, co-channel interference (CCI) modeled by Rayleigh distribution, is present. An analysis of outage probability for selection combining (SC) receiver with multiple branches, used to mitigate these disturbances in the system, will be carried out. The expressions for probability density function (PDF), cumulative distribution function (CDF) and outage probability will be derived. A few graphs will be plotted and based on them an impact of fading and CCI parameters will be highlighted.
