10:30 Hybrid and Flexible Computing Architectures for Deep Learning Systems
Nabil Ouerhani (Applied Science University Western Switzerland, Switzerland)
Artificial Intelligence (AI) is literally invading all industrial sectors, from finance to retails and even to manufacturing. Deep Learning, which is a branch of AI has been an important enabler in this spectacular evolution of AI systems. However, most of the innovations and value creation in the field of deep learning systems are dominated by big players like Google, Facebook, Amazon, Apple and IBM. Two reasons among many others could explain this monopole. First, deep learning based systems need huge amount of training data in order to achieve acceptable accuracy and performance. Unlike small players, the mentioned big players dispose of enough training data. Secondly, designing and tuning deep learning based systems, which can be deployed for real world applications, requires considerable effort. The BonsEyes project, funded by the EU commission through its Horizon 2020 Research and Innovation Program, has the objective to address these challenges in order to allow also small players to build deep learning based systems by providing a data market place for data and models and also by decreasing the needed development and deployment effort. The University of Applied Sciences Western Switzerland (UAS WS), which is a partner of the BonsEyes project, is responsible for the Work Package "Universal Developer Reference Platform". This work package aims at providing guidelines and sample implementations to deep learning systems developers with the goal to speed up the development cycles of end-to-end deep learning based systems. Thanks to the outcome of this WP, deep learning system developers are expected to have the flexibility to develop and deploy their applications on the edge or on the cloud or even combining both alternatives depending on their specific needs and constraints. The development cycle acceleration will be achieved at two major stages of the entire deep learning systems. The first stage is the development and deployment of edge deep learning applications, the inference phase, on embedded devices. The second stage concentrates on the integration of the embedded deep learning applications into a wider Internet of Things ecosystem with two main goals: 1) the connection of the embedded deep learning system to business applications that exploits the data provided by this system and 2) the delegation of certain classification and recognition tasks to the cloud-based deep learning capabilities due to lack of computation power on the edge. As for the acceleration of embedded deep learning applications and systems, the project will provide software and hardware components that help developers to port existing models and application to different target embedded platforms. The main contribution will be the generation of application codes and executables out of a set of specifications (network model architecture and parameter weights). The generated codes and executables will run, seamlessly, on a set of pre-selected embedded target platforms. For the acceleration of the integration of the embedded deep learning systems into a wider IoT ecosystem, the project will extend the FIWARE platform to cope with our reference platforms. Connectivity challenge of heterogeneous devices in terms of communication protocols and data formats will be addressed by the project. The delegation of inference to external deep learning facilities will also be addressed by the project. The adaptation of existing general or specific enablers as well as the development of own enablers will be kept as alternatives to achieve the envisioned results.

11:30 Video Quality Monitoring by using Satellite Receiver Bit Error Rate
Ioan Tache (University Politehnica Bucuresti, Romania)
This paper aims to determine the video quality dependence on Bit Error Rate measured at the end user satellite receiver, through experimental measurements performed on satellite broadcasted television channels. The results proved that if the Bit Error Rate is below a threshold value the video quality is very good. The threshold value depends on the broadcasting and video compression standards and on the video content type. By using these threshold values, the satellite television service providers are able to monitor the video quality at the end user terminal by monitoring the Quality of Service parameters and mainly the Bit Error Rate, without using measurement solutions that involve expensive Perceptual Video Quality and Quality of Experience field monitoring equipment.

Ilija Radovanovic (ICEF, Serbia); Ivan Popovic (School of Electrical Engineering, University of Belgrade, Serbia); Dejan Drajic (DunavNET, Serbia)
This paper presents the design concept of multi channel based sensing application at the physical edge of IoT network. The approach is based on reference Fog computing model, where sensor devices are connected to the edge fog node enabling the implementation of distributed real-time sensing application. The proposed concept implies that the sensor data processing is moved to the connected fog node, reducing hardware and power requirements of the sensor device. The reference fog node architecture, as well as application layer services for data communication, aggregation and processing are also given.
11:50 FRRED: Fourier Robust RED Algorithm to Detect and Mitigate LDoS Attacks
Zhaomin Chen (Nanyang Technological University, Singapore); Diep Pham (Nanyang Technical University, Singapore); Chai Kiat Yeo, Bu Sung Lee and Chiew Tong Lau (Nanyang Technological University, Singapore)
As most of consumer electronics are connected to the Internet, network attacks can cause massive damage and loss of data to the users. By sending periodic packet bursts to bottleneck routers, Low-Rate Denial-of-Service (LDoS) attacks can degrade the throughput of TCP applications while being hard to be detected. In this paper, we introduce Power Spectrum Density Entropy (PSD-entropy) to detect LDoS attacks. We also propose a Fourier transform based Robust RED (FRRED) queuing algorithm to preserve TCP throughput when faced with LDoS attacks. This novel Active Queue Management (AQM) Algorithm firstly detects the suspicious attack packets based on their arrival time and then filter the attack packets based on Power Spectrum Density (PSD) entropy. We perform extensive simulations in NS-3 to evaluate the performance of FRRED. Compared to other AQM algorithms, FRRED has the lowest False Positive Rate and can preserve nearly the full TCP throughput.
12:10 Using Software Defined Radio for RF Measurements
Dusan Grujic (School of Electrical Engineering, University of Belgrade & Lime Microsystems, Serbia); Pavle Jovanovic and Milan Savic (Lime Microsystems, Serbia)
Internet of Things (IoT) is driving the need for wireless connectivity to unprecedented scale. High development costs and risks of ASIC development have been deterring startups and small companies to innovate and disrupt the IoT market. Software defined radio (SDR) platforms have democratized wireless innovation, allowing everyone to enter markets reserved for big players. Although SDR platforms are intended for wireless communications, they can be used for RF measurements as well. This paper presents the (mis)use of LimeSDR for RF measurements.
12:30 Architecture and Partial Implementation of the Remote Monitoring Platform for Patients with Movement Disorders
Lazar Berbakov (Institute Mihailo Pupin, Serbia); Bogdan Pavkovic (RT-RK, Novi Sad & FTN, Novi Sad, Serbia); Vladana Marković and Marina Svetel (Neurology Clinic, Clinical Center of Serbia, Belgrade, Serbia)
In the coming years, the Internet of Things offers great promises for healhcare. The possibility to remotely monitor patient's vital parameters offers a number of benefits: doctors can be aware of patient's condition in real time and timely react in the case of emergency. Besides, patients are much more comfortable to stay at homes while avoiding expensive hospitalization costs. In this paper, we propose an architecture of a remote monitoring system for patients with movement disorders. We have developed one of building blocks - wireless inertial sensors platform that can be used in evaluation of therapy effectiveness for patients with spasmodic torticollis. Finally, we have demonstrated the effectiveness of our prototype TremorSense application: by analysing measurements acquired from patients with head dystonic tremor we have numerically confirmed effectiveness of the botulinum toxin injection treatment.

14:15 Virtual Environments For Training Visually Impaired For A Sensory Substitution Device
Alin Moldoveanu (Politehnica University of Bucharest, Romania); Iulia Stanica and Maria-Iuliana Dascalu (University Politehnica of Bucharest, Romania); Constanta-Nicoleta Bodea (Bucharest University of Economic Studies, Romania); Daniel Flamaropol, Florica Moldoveanu and Bogdan Taloi (University Politehnica of Bucharest, Romania); Runar Unnthorsson (University of Iceland, Iceland)
Virtual reality represents an emerging technology, which can be successfully used to develop training tools in many domains, such as military, space, education or healthcare. The current paper proposes a training strategy for a sensory substitution device in order to improve the ability of visually impaired people to be autonomous, thus to increase the quality of their lives. The core of the strategy is a highly interactive virtual training environment, composed of 3D scenes simulating both realistic and imaginary settings. The training is based on gamification principles, as the virtual environment is designed as a highly immersive serious game, with essential elements such as quests, rewards or increasing complexity of tasks which can maintain its users motivated and help them acquire useful day-to-day life skills. Also, a series of mini-games are available in the training environment, as repetitive actions can facilitate the improvement of specific skills. By using appropriate hardware equipment, the virtual training environment can be rendered to the visually impaired users through acoustic and haptic means. The paper presents our proposed training strategy based on virtual reality in the context of numerous challenges of offering efficient training experiences to users with special needs.

The system has been developed throughout the past two years and it has reached the state of the first in-vivo tests with the patients. The initial testing sessions were directed towards discovering any potential improvements that can be brought to the system regarding ease of use, comfort as well as performance and accuracy. The feedback received from the patients showed the great potential TRAVEE has in the field of rehabilitation as well as the openness of the patients towards a VR rehabilitation solution.
14:55 Smart Home Based Patronage Solution
Dmitry Vavilov (T-Systems RUS, Russia); Alexey Melezhik (Gazprom Promgaz, Russia); Ivan Platonov (St.-Petersburg State Polytechnical University, Russia)
Smart Home deployment remains within the early adopter phase. In spite of relatively moderate penetration of the patronage and healthcare functionality in the already installed devices, this feature is considered as one of the highest potential drivers for Smart Home deployment. We suggest the complex approach for medical assistance based on Smart Home usage. We propose also how to organize the human activities in response for received alarms. Several scenarios are discussed to demonstrate the alarm response procedures. A patronage service is considered as one of the actors in these scenarios.

15:30 Acquisition of current impulses in electrical discharge machining
Branislav Batinic (Faculty of Technical Sciences, Serbia); Dragan Rodić, Nikola Laković and Marin Gostimirović (University of Novi Sad, Serbia); Nenad Kulundžić (Faculty of Technical Sciences, Serbia)
This paper presents a solution for the acquisition of electrical impulses generated in electrical discharge machining of material. These electrical impulses may be relevant when examining the material properties. Although the device used for electrical discharge machining doesn't have the possibility for this aquisition, choosing the predefined processing condition predicts arithmetic mean of electrical impulses, and that is the reason to expect a certain roughness of the processed material. Upgrading the acquisition system to the existing device enables continuous recording of impulses during processing. The measuring device consists of a sensor that works on the Hall element principle, a microcontroller which collects and sends data and the softeare on the PC that performes data acquisition. Maximum detection speed of electrical impulses of the measuring device is 1 Msps, in the 10—bit resolution, and the amplitude of the electrical impulse is 30 A. The sensitivity of the electrical sensor is 66 mV/A.
15:50 Modular WSN Node for Environmental Monitoring with Energy Harvesting Support
Zivorad Mihajlovic, Vladimir Milosavljevic and Ana Joza (Faculty of Technical Sciences, Serbia); Mirjana Damnjanovic (University of Novi Sad, Faculty of Technical Sciences, Serbia)
Environmental protection is one of the most challenging tasks for humanity. All of the latest technologies to certain extent are applied in this area, among others, wireless sensor networks as well. In this paper a wireless sensor node designed specifically for monitoring of environmental parameters is described. The main advantage of this node is the use of energy harvesting techniques and supercapacitor as power supply method. The absence of batteries affects the reduction of maintenance costs and environmental impact. The paper shows that combination of energy harvesting and supercapacitor represents a sustainable solution of constant power supply of wireless sensor network node.
16:10 Online Power-Aware Scheduling Strategy Based on Workload Power Profile Measurement
Ivan Popovic (School of Electrical Engineering, University of Belgrade, Serbia); Strahinja Jankovic and Lazar Saranovac (University of Belgrade - School of Electrical Engineering, Serbia)
Deeply embedded systems represent large portion of devices connected in Internet of Things. Because of great number of deployed devices, power management of deeply embedded systems is an emerging aspect of their operation. The most actual power management techniques are hardware-centric and do not take run-time workload execution properties into account. We propose a novel power aware scheduling strategy for deeply embedded systems. Task-based power profiling is used to generate task power model utilized for power-aware or energy-aware task scheduling. The proposed concept dynamically changes the scheduling parameters of best-effort tasks to fit optimization goal while maintaining system hard real-time requirements. Concept is application design agnostic and can be easily integrated as a power management service available under real-time operating system support.

This paper presents an extension of Valgrind framework for dynamic binary code analysis to support MIPS MSA instruction set which includes instructions for vector (SIMD) processing of integer and floating-point data of different widths. First, a background on MIPS and its MSA extension is given. Then, Valgrind features for code instrumentation are described. Several changes have been made to Valgrind intermediate representation in order to support new instruction set. The implementation issues regarding the structures, formats, and functions needed for extension are discussed. Some low-level details and examples are also presented. Upgraded Valgrind tools are verified using dedicated regression test suite on the Linux platform.

The low power stochastic sensor is proposed, and its suitability for operation in Internet of Things (IoT) environment is emphasized. Unlike typical digital sensors, instead of a digitizing module, this sensor has a digital stochastic measurement module (DSMM). DSMM enables low-power yet fast and accurate functioning of the sensor. Assessment model includes test signal generator, the standard calibrator, DSMM of the sensor.

Harald Zophoniasson, Christian Bolzmacher, Margarita Anastassova and Moustapha Hafez (CEA LIST, France)
We present a study on the influence of the applied force on tactile perception thresholds, during exploration of tactile textures generated with electrovibration. From a first user study, three force levels corresponding to the light (0.2 N-1.5 N), medium (1.5 N-3.0 N), and high force (3.0 N-7.0 N) categories were deduced. In a second study, the users were asked to apply these force levels while following a line on the screen. We determined the perception thresholds of 10 participants for specific electrovibration stimuli (100 Hz, 160 Hz, 240 Hz, 360 Hz, and 540 Hz sinusoidal signals) using a staircase method. No force effect on the perception threshold has been measured for 100 Hz and 160 Hz, while it decreased with increasing applied force at 240 Hz, 360 Hz, and 540 Hz.

The fast popularization of virtual reality equipment has brought unrivalled convenience and entertainment experience in human life. Cardboard, Oculus Rift, HTC Vive and PSVR are gradually being accepted and recognized. The realization of VR for information purposes and remote exploration of new areas will become the key point of the application of VR technology in the field of education. This paper demonstrates the realization of VR for information purposes and remote exploration of new areas using HTC Vive. By using HTTP requests, official announcements from the faculty can also be fetched and presented to the user. We propose a system to match a given pair of virtual and physical world for immersive VR navigation. We first take images of the physical world in order to model it via the photogrammetry method. The second task is to 3D model the environment in Blender with all the props in it. After that, custom textured model is introduced to Unity game engine where all the scripting is done.
