In this paper, an Environmental Decision Making Tool with Renewable Energy (EDMTRE) is proposed with the resources cost as constraints. Modifed ReCiPe Version 1.3 Model is adopted to represent the midpoint indicators. A three-method hybrid; Modified Firefly Algorithm with Levy Flights and Derived Mutation (MFA-LF-DM) with parameters brightness, distance, attractiveness, movement, randomness reduction...
Recently, there has been a lot of researches on various methods for a sensorless control of permanent magnet generators (PMG) in wind turbines. The sensorless control of the PMG considers estimations of a rotor angle and speed which are based on the PMG parameters estimation. The parameters that have been estimated are stator resistance, rotor flux, d-axis and q-axis inductance. For more precise rotor...
On Load Tap Changer contacts are the only movable, and thus the most sensitive part of the power transformer. Over time several diagnostic methods for condition assessment of these contacts have been developed. Some of them are based on invasive procedures, such as dynamic resistance measurement, while others are less invasive, such as those based on observation of the vibration fingerprints. Fractal...
The distributed storage systems (DSS) are constructed by large number of nodes which are interconnected over a network. Each node in the network is vulnerable and a potential risk of attack. The attackers can eavesdrop the nodes and possibly modify their data. Despite the considerable efforts, both in industry and in academia, high reliability and security remain major challenges in running large...
The dawn of 5G requires significantly higher data rates, not only for the Radio Access Technology (RAT), but also for the transport network. Line-of-Sight MIMO links based on mmWave radios promise reaching ultra-high throughput with reasonably small antennas. mmWave links with optimally arranged antennas are one viable concept for spatial multiplexing, capable of potentially achieving Gb/s data rates...
The main aspect considered in this paper is a comparison of interleaver sizes for convolutional and low-density parity-check codes (LDPC) employed for 100 Gbps wireless communication at 240 GHz with parallel sequence spread spectrum (PSSS). Interleavers required for PSSS-15 and convolutional codes are larger in silicon area than a complete Reed-Solomon decoder. Thus, convolutional codes are not recommended...
In this project, we developed a chess play system based on Kinect vision sensor, which recognizes different hand gestures as a command and sends these commands to V-REP robotic simulation tool. Delta type robot will play chess according to the commands sent via vision software. In our system, we have tested for 2 different chess opening scenarios and DOF checking mode scenario, then we obtained results...
Wireless communications is one of the fastest growing technology fields, driving numerous other innovations in electronics. One challenging research area within the wireless field is to achieve a higher transmission speed. Today it is an open question how we can realize a wireless system at a speed of 100 Gb/s or even beyond. If we intend to use such systems in a mobile environment, we can only afford...
Recently multi-agent patrolling became more and more crucial in security, monitoring, etc. applications. It can be used, for example, to monitor points of interest in space, such as measurement points or entrances to a guarded area. A good patrolling strategy would ensure frequent visits to all points of interest defined by a user. A variety of centralized and distributed approaches exist already...
An optimum resource partition decision model for a class of warfare command systems in conflicts of two opponents, where the total forces of operational side is not superior to the forces of enemy side, on the grounds of Lanchester square law equations has been developed. The issue on how to solve the maximum residual strength of the operational side against the enemy is thoroughly addressed. The...
eHealth technology can bring a variety of benefits to patients, caregivers, and health institutions, by facilitating improved healthcare services through the utilization of Information and Communication Technologies (ICTs). The forthcoming generation of healthcare services will require advances in computing and Wireless Sensor Networks (WSNs) in order to leverage truly intelligent and adaptive features...
This paper presents a high resolution method for analyzing of electrophysiological activities using Matrix Pencil Method (MPM). This approach identifies measured signal from nerves to better understanding the functional organization of neuronal ensembles that form the peripheral nerves or the cerebral cortex. Matrix Pencil Method which is used to extract original signals and benefits from minimum...
Today there exist many different types of smart assistants and devices, such as virtual assistants, smartphones and wearables, which have a purpose to coordinate and optimize the daily activities of the people worldwide. The smart assistants' focus is mainly on basic human needs, e.g. browsing, scheduling, navigating and other similar activities. However, not many smart assistants are concerned with...
In this paper, we overview current products available on the market, patents, and state-of-the-art of research for cloud solutions based on wearable ECG biosensors. Building a medical cloud that uses such sensors motivates us for a 24h healthcare monitoring service. Furthermore, we identify several challenges, which have to be solved to enable a complete solution for a generic medical cloud capable...
In clinical applications, peripheral nerve stimulation is usually delivered by means of commercial devices. The main use of these devices is Transcranial Magnetic Stimulation, in fact the coils are designed for a good stimulation of brain. The purpose of this paper is to design a new coil for magnetic stimulation of nerves, which allows a deep stimulation but, at the same time, characterized by high...
The paper shows the results of experiments performed at cultures of the anterior pituitary gland cells of domestic pig (Sus scrofa domestica) in vitro. The cells were subjected to the influence of electromagnetic field of extremely low frequencies (60 and 120 Hz) by two hours. We analyzed the cell cycle progression and the metabolic activity. The analysis of the viability and the cell cycle was performed...
In this paper, we present a new loT-based health monitoring approach in which collected medical sensor data is sent to an analysis module via low-cost, low-power and secure communication links provided by a LoRaWAN network infrastructure. We mainly focus on monitoring blood pressure, glucose and temperature in rural areas where cellular network coverage is either absent or does not allow data transmission...
This paper presents an idea of using an Electronically Steerable Parasitic Antenna Radiator (ESPAR) for jamming suppression in IEEE 802.11b networks. Jamming (intentional interference) attacks are known to be effective and easy to perform, which may impose connectivity problems in applications concerning Internet of Things (IoT). In our paper, theoretical considerations are presented and the results...
