This paper provides a novel characterization of nested complexes in protein interaction networks, stressing definition and representation issues, quantification, biological validation, network metrics, motifs, modularity and gene ontology (GO) terms. This characterization can be used in the design of a nested protein complex prediction algorithm. We introduce the "nested group" concept as...
This work presents an application of the artificial neural networks (ANN) in the prediction of the time series of the weekly wholesales of bottled propane gas (13 kg. Bottles). For this purpose several networks with different topologies were built. In order to reduce the error of the predictions, many schemas of ensembles were applied. Additionally, given the scarce data available, it was mandatory...
There is an increasing demand for indoor navigation and localization systems along with increasing popularity of location based services in last years. The paper presents our work in progress for locating indoor objects based on signal fusion. The location is based on two signals: RSSI (Received Signal Strength Indication) and video camera. This paper presents a vision-based system for human detection...
In this work a new version of Enhanced Multivariance Products Representation (EMPR) is taken into consideration. Recent researches on the bivariate arrays (i.e., Matrices) have led us to a new scheme which we have called Tridiagonal Matrix Enhanced Multivariate Products Representation (TMEMPR). Therein we have been consecutively using four term EMPR on its bivariate component under different support...
For the power system of a certain small enterprise, different start up modes of the induction motor are analyzed by simulation. The dynamic curve of motor slip, motor torque motor current and bus bar voltage in different starting modes are obtained through simulation. The effect of different start up modes on start-up time, starting torque, power grid voltage and the stability of the power system...
The paper presents a Genetic Algorithms technique, used to optimize project schedule created in Microsoft Project. The proposed model is called OPTPROJECT. The proposed application is simple and at the same time general enough for optimization of projects, where the high cost activities have to be performed last (at the end of the project). It can be used to manage both small and large projects.
This paper is focused to the designing, implementing and benchmarking the data cluster based on the CEPH [1] technology. The main point of this paper is aimed to the implementation with geographically separated nodes. These nodes, store points of distributed data cluster, is in different location and on different subnets. Realized test show the dependency of number of concurrent clients connected...
In the area of recommender systems, user-based collaborative filtering algorithm has been extensively studied and discussed. In the traditional approach of this method, a target user's preference for an item is predicted by the integrated preference of the user's neighbors for the item, ignoring the structure of these neighbors. That is, these neighbors form two distinct groups: some neighbors may...
This paper presents an online reinforcement learning based application which increases the revenue of one particular electric vehicles (EV) station, connected to a renewable source of energy. Moreover, the proposed application adapts to changes in the trends of the station's average number of customers and their types. Most of the parameters in the model are simulated stochastically and the algorithm...
In this paper the possibility of using artificial neural network (ANN) in the classification of force profiles of different striking techniques is deeply analyzed and discussed. Classification of direct punch force profiles is presented in this paper alongside with results of previous research of kick techniques classification. The results are summarized in tables and followed by discussion.
Mobile Communication System (MCS) is an important element for ensuring information support in crisis and in battle action. The transit network or the network of base stations is the basis of MCS. Checking a designed radio relay links is the basis for MCS planning. This verification is performed by checking line of sight between selected locations. But there can be other circumstances influenced deployment...
The global optimization of a mathematical model determines the best parameters such that a target or cost function is minimized. Optimization problems arise in almost all scientific disciplines (operations research, life sciences, etc.). Only in a few exceptional cases, these problems can be solved analytically-exactly, so in practice numerical routines based on approximations have to be used. The...
This article focuses on heat radiation intensity optimization across the surface of an aluminium mould. The inner mould surface is sprinkled with a special PVC powder and the outer mould surface is warmed by infrared heaters located above the mould. This is an economic way of producing artificial leathers in the automotive industry (e.g. The artificial leather on a car dashboard). The article includes...
