In this paper was developed a dynamic model of multipath routing based on balancing lengths of queues at the routers of telecommunication network represented by a system of linear differential equations of queue buffer utilization. The novelty of represented model is a modification of the conditions of balancing lengths of queues to take into account the priorities and lengths of packets in queues. Proposed model allowed to convert the solution of multipath routing based on balancing lengths of queues to solution of problem of optimal control. Using the solution proposed allows to organize a more effective control of buffer and link network resources due to the consistent solving of multipath routing and balancing lengths of queues problems in accordance with the concept Traffic Engineering Queues. © 2015 Kharkiv National University of Radioelectronics.

Solution of actual scientific and practical problem associated with the development of flow-based model of multipath routing with traffic policing rejection balancing was presented. Within the proposed model consistent solution of problem of multipath routing with traffic policing rejection balancing converged to solution of optimization problem of linear programming with the optimality criterion as minimum of dynamically managed upper bound of rejections for all flows in a whole network. Numerical examples of multipath routing with traffic policing rejection balancing problem solving confirmed the adequacy and effectiveness of the proposed solution. Investigation of processes of multipath routing with traffic policing rejection balancing using the proposed model showed that the flow rate restriction on the network edge has an adaptive nature. © 2015 Kharkiv National University of Radioelectronics.

Schemes for protection of a node, a link and a rout under fault-tolerant multicast routing are presented for a multiflow case. The schemes are based on a nonlinear flow model which has the conditions for preventing links overload modified for a case when not all flows can switch to backup routs but only some of them. Scheme operability is demonstrated on a numerical example which has proven effectiveness of the proposed solution for the multiflow case. © 2015 Lviv Polytechnic National University.

The paper presents the flow-based queue management model on telecommunication networks routers based on optimal flow aggregation and packets distribution in queues. The novelty of the model is that with flows distribution in queues it is carried out its aggregation based on flows and queues classes comparison within the analysis of the set of classification indicators. © 2016 National University Lviv Polytechnic.

To improve scalability of multicast routing solutions the method of hierarchical routing with coordination was proposed. It is based on the decomposition representation of the flow-based model of multicast routing. The usage of this method allowed decentralizing the calculation of the multicast routes in the border routers of telecommunication networks. © 2016 National University Lviv Polytechnic.

In this paper, the optimization of a nanofluid-cooled microchannel heat sink was reported. Al2O3-NH3 with three different volume fractions (1 %, 3 % and 5 %) was examined. An optimization scheme which is comprised of two objective functions (thermal resistance and pumping power) and the elitist non-dominated sorting genetic algorithm (NSGA-II) was employed to optimize the overall performance of the considered system. Under the same operating conditions, the ammonia-base nanofluid (Al2O3-NH3) exceeded other coolants (Al2O3-H2O and H2O) in terms of the required pumping power (0.144, 1.015 and 0.94 W for Al2O3-NH3, Al2O3-H2O and H2O, respectively). When the refrigerant base nanofluid is used as a cooling fluid, a lighter heat sink was produced. Finally, more studies should be dedicated to explore this nanofluid and the possibility of considering it for electronic systems cooling. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

Green chemistry means utilization of various plant resources for the synthesis of metallic nanoparticles. In the present study silver nanoparticles was synthesized in a single step by a green biosynthetic method using an extract of Crocus Sativus L act as a reducing and capping agents. The nanoparticles were characterized usingUV-Vis, Xray diffraction (XRD) and Dynamic light scattering (DLS) .The prepared silver nanoparticles(AgNPs) showed surface Plasmon resonance centered at 440 nm. The XRD pattern showed the face centered cubic structure of silver nanoparticles. The size rangefrom19.9nm to 28.1nm was determined by using laser particle size analyzer. The current research work investigates the findings of optimization of different experimental variable conditions like time,temperature,reaction pH, silver nitrate concentration and the mixing ratio of the reactants on silver nanoparticles synthesized. The optimized condition for the synthesis of silver nanoparticles revealed that silver nitrate concentration was 1 mM, temperature was70°C, PH was 9, incubation time 1 h and aqueous extract and silver nitrate ratio was 5:95.

The optimization of a nanofluid-cooled rectangular microchannel heat sink is reported. Two nanofluids with volume fraction of 1%, 3%, 5%, 7%, and 9% are employed to enhance the overall performance of the system. An optimization scheme is applied consisting of a systematic thermal resistance model as an analysis method and the elitist non-dominated sorting genetic algorithm. The optimized results showed that the increase in the particles volume fraction results in a decrease in the total thermal resistance and an increase in the pumping power. For volume fractions of 1%, 3%, 5%, 7%, and 9%, the thermal resistances were 0.072, 0.07151, 0.07075, 0.07024, and 0.070 K/W for the SiC-H2O while, they were 0.0705, 0.0697, 0.0694, 0.0692, and 0.069 K/W for the TiO2-H2O. The associated pumping power were 0.633, 0.638, 0.704, 0.757, and 0.807 W for the SiC-H2O while they were 0.645, 0.675, 0.724, 0.755, and 0.798Wfor the TiO2-H2O. In addition, for the same operating conditions, the nanofluid-cooled system outperformed the water-cooled system in terms of the total thermal resistance (0.069 and 0.11 for nanofluid-cooled, and water-cooled systems, respectively). Based on the results observed in this study, nanofluids should be considered as the future coolant for electronic devices cooling systems.

Arabic language is a unique language because of its pronunciation of the word written. The formation of more than two Arabic letters will translate to a different meaning. This paper presents an alternative translator from Arabic word to English word by using an equation for the formation of the Arabic letters. The morphological model of Arabic language is used in order to use the equation to put diacritics according to Arabic grammatical rules. A system is then developed based on the morphological model. The input of the system is the Arabic word. The system uses morphological Arabic Natural Language Processing (ANLP) and translates the Arabic word into English word. The output of the system shows percentage of the successful translated words. We tested our system by using 11 Arabic words. The results show that 9 out of 11 Arabic words (81.81%) were successfully translated by conducting the process of diacritics in the morphological model of Arabic language. We also perform a quality assessment to calculate the efficiency and effectiveness metrics based on the ANLP developed. Based on the result, the system can be used as an alternative translator from Arabic word to English word. © 2015 IEEE.
