Multilevel system architecture of energy efficiency management in the region is developed in this work. The architecture model consists of three levels, namely, level of data collection and management of executive mechanisms, level of control and management of technological process, and level of operator control and formation of administrative decisions. Hardware and software of each hierarchical...
This paper presents a scheme which aims to track patients in hospitals and to generate the suggestion information to the patients. In this scheme, hardware like location tracking devices such as GPS, WiFi positioning system, Bluetooth Low Energy (BLE), and RFID is not required. Instead, the proposed system entirely relies on the existing data in the Hospital Information System (HIS). The data analytics...
This paper investigates the suitability of employing various measurable features derived from multiple wearable devices (Apple Watch), for the generation of unique authentication and encryption keys related to the user. This technique is termed as ICMetrics. The ICMetrics technology requires identifying the suitable features in an environment for key generation most useful for online services. This...
An accurate detection of spectrum opportunities is a key factor in governing the efficient spectrum usage in a cognitive radio (CR) system. Energy detection based spectrum sensing has been widely used due to its ease of implementation with lower computational complexity; however, its robustness and performance are highly affected by the noise uncertainty. In the present work, a real time hardware...
This article presents a system for determining the position and orientation of unmanned aerial vehicles. The system has two hardware layers coupled in both directions. One layer stabilizes the vehicle while the other determines lateral displacements. The two-directional coupling between layers allows the system to minimize estimation errors. The proposed implementation is evaluated on real hardware...
Assisted living and home monitoring systems are gradually becoming a necessity, considering the current trends in population ageing and older adults' desire to continue living independently in their homes and their communities for as long as possible. This paper presents our current achievements regarding the implementation of a cyber-physical system for assisted living and home monitoring, developed...
In this report, we suggest an approach to fault-tolerant multichannel digital averaging converter based on the usage of original structural organizations of hardware systems. Such systems are oriented on the processing of the measurement results presented in the pulse stream forms and perform primary functional conversions of pulse data flow on the base of integration of informational processes of...
Most underwater deployments rely on acoustics for enabling communication. The equipment for underwater communication is usually very expensive. Simulations of underwater systems are insufficient for many researchers. An open source platform built with commercially available hardware at low rates along with customizable software modules may prove to be very useful for researcher. This paper particularly...
For environmental impact analysis remote hosting of instrumentation system consisting of sensors provides a seamless, authentic method of establishing communication. These methods provide the on the spot parametric measures for prediction analysis and disaster management. Though the drones provide visual imagery of the impacted area, they are faced with payload and power limitations when sensors are...
This paper contains presentation of the flexible control system for an autonomous UAV (unmanned air vehicle). The complete description of hardware and software solutions used to realize autonomous flight are presented in this work. Main objective of the research was to develop software which provides ease of adjustment and extendibility to drone system with different equipment. Presented system is...
Vacuum technology is a very widespread area. Nowadays, a broad variety of applications can be found to be using vacuum and vacuum related monitoring. Vacuum profile for different applications can be different, but whatever that may be, monitoring it is an essential part of any such application. Thus, this paper describes the development of one such vacuum profile monitoring system that can be re-purposed...
There are almost no on-board intelligent anomaly detection systems in most of the existing unmanned Aerial Vehicles (UAVs), and the flight status assessment still depends on ground control station. While, this method can't meet the requirement of real-time anomaly detection for UAV autonomous and safe flight. In order to achieve real-time monitoring of UAV flight status, and improve the reliability...
Modern mechanical engineering systems are primarily designed to perform a specific system process in an optimal manner. For this purpose, they use control systems that monitor and influence the process with the help of sensors and actuators. Changing control values or (physical) disturbances are recorded and considered by the control systems. Problems arise whenever the disturbances are not physical,...
The design of intelligent powered wheelchairs has traditionally focused heavily on providing effective and efficient navigation assistance. Significantly less attention has been given to the end-user's preference between different assistance paradigms. It is possible to include these subjective evaluations in the design process, for example by soliciting feedback in post-experiment questionnaires...
This paper presents a novel control methodology which uses an extremely low-resolution encoder to achieve a desired harmonic trajectory. The particular application of interest is a cellular microinjection technology called the Ros-Drill (Rotationally Oscillating Drill) for ICSI (Intra-Cytoplasmic Sperm Injection). It is an inexpensive set-up, which creates high-frequency (e.g. 500 Hz) and small-stroke...
The Compressed Sensing (CS) framework is heavily utilized to reduce data rate in hardware restricted scenarios by exploiting the intrinsic sparsity of the transmitted data. Considering multiple sensors at the same time, one variation of the Multi Channel (MC) framework takes several measurements at one time instant and then uses CS in the spatial domain to compress the data. This paper provides a...
In this paper, we present our solution to simulate home automation networks on a functional level in our research project on self-organizing home automation network nodes. We simulate the nodes with our hardware-software co-simulator, based on the virtual machine QEMU and the SystemC hardware simulator. The Virtual Distributed Ethernet suite is used to simulate several hardware-software co-simulators...
Insufficient support of electric current sensing on commodity mobile devices leads to inaccurate estimation of their battery's state-of-health (SoH), which, in turn, shuts them off unexpectedly and accelerates their battery fading. In this paper, we design V-BASH, a new battery SoH estimation method based only on their voltages and is compatible to commodity mobile devices. V-BASH is inspired by the...
In this paper, we develop a framework for an innovative perceptive mobile (i.e. cellular) network that integrates sensing with communication, and supports new applications widely in transportation, surveillance and environmental sensing. Three types of sensing methods implemented in the base-stations are proposed, using either uplink or downlink multiuser communication signals. The required changes...
Autonomous and semi-autonomous aerial systems (AES) are vehicles which have to perform tasks in complex and dynamic environment, for example in logistics and transportation applications. In this context vehicle's behavior has to be verifiable safe. Here safe behavior denotes interaction with the environment like for example spacial movements with freedom of unacceptable risk. Traditionally, behavioral...
