Over the next years the demand of wireless communication will increase tremendously. More and more mobile end devices require a high data rate connection e.g. to a smart home (Internet of Things, IoT) or to the internet. The radiation power pattern of base stations and mobile end devices will completely change for the 5G technology. Therefore the electromagnetic exposure especially to human body will...
Lightning is one of the main causes of damage to wind turbines. The continuous increase in the wind turbine heights makes these structures even more vulnerable against lightning. As a result, the design of proper lightning protection system is of high importance. The paper deals with the determination of the transient impedance of wind turbines via different approaches. The analysis is carried out...
Stemming from a holistic view of interrelated frailties, cognitive decline, physical frailty, depression and anxiety, social isolation and poor sleep quality, My-AHA proposes an ICT platform for early detection of pre-frailty and intervention to sustain active and healthy ageing and slowing or reversing further decline. The main aim of My-AHA is to reduce frailty risk by improving physical activity...
In this paper a novel 60 GHz printed antenna with defected ground structure is proposed for MIMO application. The antenna consists of a pairs of folded L-shaped strips patch printed on silicon subtract for wireless personal area network (WPAN) at 60 GHz. The two radiating elements are separated by distance equal to 1.25 mm. The performance of the proposed antenna has been evaluated after adding the...
In this paper, we present the transmitter and receiver multiple-folded design for maximizing power transfer efficiency (PTE) for wireless power transfer (WPT) systems at 6.78 MHz. Using this design, it is possible to achieve higher PTE than the one obtained with square loops provided in the standard. The multiple-folded antennas are designed and tested with numerical electromagnetic software in free...
In this paper, we consider a Joint Channel Network Coding (JCNC) scheme applied to Multiple Access Relay Channel (MARC) for correlated sources. Then, two correlated sources send their messages to one destination and one relay which performs network coding and provides additional information to the receiver. At the destination, a joint iterative decoding algorithm is developed which takes into account...
Microwave power standard is significantly limited by thermostat quality (± 1 mK/h), bolometer load efficiency (absorbers) and characteristics of adiabatic line due frequency bandwidth. Several years ago, air gap was applied on coaxial adiabatic line in order to drive down heat effects. In this paper, the focus will be on further analysis of coaxial line with an applied air gap. With the finite element...
The promise of smart cities offers the potential to change the way we live, and refers to the integration of IoT systems for people-centred applications, together with the collection and processing of data, and associated decision making. Central to the realization of this are wearable and autonomous computing systems. There are considerable challenges that exist in this space that require research...
Our personal data is now more valuable than ever. The uncontrolled growth of internet-centered services has led us to accept many compromises about how we share it. In the era of Internet of Things, personal data is collected continuously. Now, more than ever, we are in need of privacy-preserving applications where users always retain control of their personal data. In this paper, we present a secure...
The paper reviews the radiation phenomena in classical electromagnetics in terms of microscopic and macroscopic approach, respectively. First, the radiation from an accelerated charged particle is outlined featuring the concept of radiation reaction force. Then the Pocklington integro-differential equation for dipole antennas is derived which is followed by the details related to the numerical solution...
In contemporary digital communications design, two major challenges should be addressed: adaptability and flexibility. The system should be capable of flexible and efficient use of all available spectrums and should be adaptable to provide efficient support for the diverse set of service characteristics. These needs imply the necessity of limit-achieving and flexible channel coding techniques, to...
Within the frame of the fourth industrial revolution, also known as Industry 4.0, industrial cyber-physical production systems (ICPS) have experienced a significant progress. To this end, Industry 4.0 has brought upon an improved, flexible, and cost-efficient system architecture that can sustain the development of innovative applications and services. Nonetheless, this technological advancement also...
ElectroCardioGram ECG biometrics has recently been identified as a promising technique to identify subjects. Meanwhile, as ECG related data can reveal other factors like medical disease, the protection of the ECG biometric template is mandatory. The challenge is to guaranty the privacy of the ECG data, while keeping adequate performance results in terms of false acceptance rate and false rejection...
Smart devices can be considered an essential element of the Internet-of-Things (IoT) revolution. Devices able to gather and process data to provide high-level information to other nodes will enable advanced and effective smart applications in the near future. To let IoT objects to become smarter and smarter, advanced embedded architecture must be considered. In this direction, this paper exploits...
This paper tries to shed more light on Mirai malware, with an aim to facilitate its easier detection and prevention. This malware was used in several recent high profile DDoS attacks. Mirai is used to create and control botnet of IoT devices. The code of this malware is analysed and explanation of its parts provided. Virtual environment for dynamic analysis of Mirai is created. Special settings that...
This paper describes the implementative aspects, the main challenges and the adopted solutions for an Internet voting system designed by LepidaSpA and dedicated for specific elections a Land Reclamation Authority in Italian Emilia-Romagna region. Besides the description of the voting system, we also present an efficient and simple administration tool for the management of all the election phases,...
In this research study we investigate whether AC-ware Tutor supported education, along with traditional learning and teaching of high school students, contributes more to the student acquisition of knowledge. AC-ware Tutor is intelligent tutoring system, focused on automatic and dynamic generation of adaptive courseware which takes into account the current level of student's knowledge and cognitive...
