It is mandatory for organizations to keep up with rapid and continuous changes to their business processes to be competitive. Business process simulation is a preferred way to improve these changes. Many business processes can start with partially filled data and run for a few days or even longer. Such business processes are defined as long running business processes. However, business process simulation...
The usage of IEEE 802.11 wireless equipment has been growing in recent years. Nevertheless, the spectrum which is used by such equipment is already overcrowded and due to this, the performance of wireless devices is decreasing. Recently, IEEE 802.11 was updated with the latest IEEE 802.11ac version. IEEE 802.11ac provides higher modulation capabilities and more robustness against interference. With...
Defined technique of control system model design with fuzzy logic controller. Presented simulation modeling results of the system with fuzzy logic controller. The input and output linguistic variables term-set accessory functions are obtained. The input and output variables correlation is determined as rule base. The visualization of the fuzzy interface surface is achieved.
We are very glad to welcome our colleagues young scientists, researchers and practitioners to the 3rd Open Conference of Electrical, Electronic and Information Sciences (eStream'2016), held in Vilnius, Lithuania, 19 April 2016. The eStream conferences aim to disseminate the research achievements between groups of scientists and engineers working in a different areas of sciences in order to reach more...
Manoeuvring in limited spaces of car parks causes a lot of problems for drivers trying to park as well as drivers entering or leaving parking lots. The main problems include traffic jams, unexpected car accidents, and concentration of exhaust gases. Analysis of parking manoeuvres and creation of traffic management algorithms for closed spaces lead to effective planning of management of such processes...
The drawbacks of electrical balances calculation methods are considered in the paper. In order to increase accuracy of appropriate balances it is necessary to verify them via electricity meters. Due to limited number of electricity meters and time appropriate verification can be carried out only for certain amount of technological objects. The new algorithm of identification of technological equipment,...
Paper focuses on the optimization of the advertising and other additional costs for the small business ecommerce web sites. The aim of this paper was to propose a dynamic neural network based algorithm to predict number of clicks on a particular advertising link in three web pages of three different small companies working in the same business segment. The dynamic neural network based algorithm was...
In some applications, concerning the linear filtering problem, one has to process millions of signal samples. Therefore, the computation of the convolution requires a lot of time. It is known that for multi-dimensional input signals, the popular approach is to compute the convolution in the frequency domain which is sometimes referred to as the fast convolution. The fast convolution can be more efficient...
This article describes a method for flow measurement of liquids containing protons. Measurements are made using by method of interaction with the test medium in a non contact manner using fields that penetrate through the wall of the pipeline. This method is based on the effect of the nuclear magnetic resonance (NMR). The structural scheme of single-coil NMR marker-type flowmeter with a division processes...
Modern management processes rely heavily on sensory systems which register external parameters and allow to determine necessary operations. In more complex systems they are usually linked into integrated networks and applied in different industrial settings. One of such applications is the fixation of railway rolling stock in a specific road segment. Lithuanian Railways use the system based on relay...
The voltage controlled oscillator with feature when frequency response to voltage step is not instantaneous but linear in time function with controlled slope has been proposed. Additionally, the frequency time dependence slope control circuit has galvanic decoupling from output of oscillator. The voltage controlled oscillator contains two blocks: one that provides linear in time dependent voltage...
During base station subsystem (BSS) or radio access network (RAN) construction, the system capacity is planned according to the expected traffic volume in the coverage areas. When the traffic volume is within the planned capacity, the system can provide services properly. However, in certain situations, such as major events or in dense destinations, the traffic volume sometimes exceeds the planned...
The article discusses adaptive filtering in the measurement signals with complex dynamics. Smoothing is pro- posed to change depending on the dynamics. Dynamics is esti- mated by approximating the current values of linear, parabolic or other addiction. The mathematical simulation of the digital filter, the running average, and smoothing by linear and parabol- ic dependence is carried out at different...
In this paper we consider the question of synthesis a control system for temperature distributed object. According to the experimental data, the parameters of conditional centered contours describing the behaviour of the object on the control action for different points in space. Different control systems using information on the output parameter values at several points in space. It implemented a...
Iris recognition is becoming one of the most evolving and researched fields in human authentication and biometrics. Despite the fact that the topic itself is relatively young, the progress in late years has been significant. Still for most of access control and biometric identification systems based on iris pattern recognition, the biggest problem is high iris quality needed for template extraction...
The paper considers the problem appearance of inertia hanger with details at movement galvanic automatic manipulator. It explores new methods for the synthesis of optimal control system to determine the optimal function. In this paper we show the way we found an optimal control as compared with auto-tuning.
