This paper discusses an approach of the abnormal condition detection of whole blood using piezo-synthetic effects in blood under dynamic external pressure. Three groups of samples having verified chemical and biological conditions were analysed to prove reliable detection: saline, whole blood and whole blood with colorectal cancer as an example of abnormal conditions. The procedure of a discrete differentiation...
This paper discusses the solution of the logistic problem occurred in a management system to supply fuel to inhabitants in the Arctic regions using bulk water transport delivery. The suggested mathematical model of a logistic scheme is designed in the form of uniprocessor system with refillable storage component providing a single stage service of deterministic objects flow. The task scheduling optimisation...
The paper analyses computational model based on dynamic programming for platforms with multicore processors and heterogeneous architectures with FPGA. The models are applied for solving a canonical problem of dispatching where the computation time significantly depends on the problem scale factor. The parallel algorithms of NP-hard problem of dispatching are complicate and require intensive RAM data...
Wireless Network has become the critical part of the communication infrastructure in our environment. Nowadays, the using of mobile computing devices such as laptops and Wi-Fi enabled phones in the workplace is increasing. The design of wireless networks for enterprise environments remains a challenging task due to the problem of topological design. In this paper, we discuss the computational aspects...
Predefined heater parameters are involved in self-tuned temperature control for plastic moulding. However the heater system transfer function depends on many external parameters, such as barrel filling level, type of plastic etc. This paper discusses a recursive least-square estimation of plastic moulding heater parameters identification. The real heaters have been estimated by recursive least-square...
The paper discusses utilisation of the brute force methods for the task of towers distribution in wireless communication systems. The proposed algorithm allows to find an optimal allocation of a tower between the settlements. A simple wireless communication has been used as an example to investigate the functionality of the algorithm's software.
The classification of median filter hardware structure was proposed. Main differences, advantages and disadvantages of each class were described. Scalable and synthesizable Verilog-descriptions were designed for two fast hardware structures. HDL-descriptions were synthesized on Altera and Xilinx FPGA platforms, comparative analysis on the basis of resource utilization and clock rate was done.
The most important component of a closed-loop industrial control system is the communication unit located between a digital controller and the object being controlled. A pulse converter is usually used for this purpose in systems operating under pulse width modulation. However the dynamic characteristics of the converter bring a significant impact on the quality of the system regulation. This article...
The paper analyses a random pulse width modulated technique applicable for Z-source inverter. The proposed technique comprises the random pulse position PWM with a randomised frequently triangular carrier having characteristics of both space vector and random lead-lag modulations. This random pulse PWM is produced through the logical comparison of the pseudorandom binary sequence bits with the PWM...
This paper demonstrates a possibilities of using brute force methods for evaluating the effectiveness of hierarchical management systems. Proposed model of hierarchy provides finding the optimal distribution of load between the executive elements at a predetermined structure. A simple hierarchical structure has been used as an example to investigate the functionality of the model and its software...
The paper presents a new control strategy of management of transport companies operating in completive transport environment. It is aimed to optimise the headway of transport companies to provide the balance between costs and benefits of operation under competition. The model of transport system build using AnyLogic comprises agent-based and discrete-event techniques. The model combined two transport...
This paper proposes a new artificial neural network-based maximum power point tracker for photovoltaic application. This tracker significantly improves efficiency of the photovoltaic system with series-connection of photovoltaic modules in non-uniform irradiance on photovoltaic array surfaces. The artificial neural network uses irradiance and temperature sensors to generate the maximum power point...
Battery of a plug-in electric vehicle can be charged from a power grid at different locations. In case of charging at home location it performs a significant impact on household energy consumption and needs to be coordinated and scheduled in order to reduce peaks of power load and cost of electricity. This paper discusses coordination of in-home charging aimed to improve load factor and reduce cost...
