Abstract
Ischemic Stroke is a disease that inhibits blood supply to the brain. One method in handling ischemic stroke patient is Intra Arterial Heparin Flushing (IAHF) which has been claimed to be able to improve motoric function of a patient. However, in vitro clinical research to understand IAHF is scarce. One of in vitro methods can be applied is using microfluidic. This research aims to create a microfluidic system that can represents blood vessel system of a stroke patient and to quantify volumetric flow rate of 1,3-Propanediol (as a blood model) in microfluidic channels. Microfluidic which is made of acrylic with a square-wave design, is employed to represent a thrombotic ischemic stroke and embolic ischemic with the addition of wax to represent plaque in blood vessel. Various viscosity of 1,3-propanediol are applied (1.5 mPa. s; 4 mPa. s; 7.2 mPa. s) to represent the effects of heparin drug. The results indicate that fluid Reynold number in the microfluidic channel are 8.8023 x10−4 and 12.3230 x10−4 which is fall in the area of Reynold number laminar flow such as in blood vessels. Volumetric flow rate of 1,3-propanediol decreases when the viscosity increases and when wax is situated in the microfluidic channel. Diluted 1,3-propanediol (at a viscosity of 1.5 mpas) shows similar volumetric flow rate (when it passes through microfluidic channels with wax) with normal blood viscosity 4,0 mpas (when it passes microfluidic channels without wax). This similarity indicates an increase of blood flow when heparin is added in excess in IAHF method, which induces an improvement of organ motoric function.

Abstract
Most of the research on object detection that uses discussing background is only necessary for the decision of the background model by assuming all statistical objects are part of the background. This caused a debate called “foreground aperture,” where statistical purposes that represent moving backgrounds, the position of the initial object will be detected as false detection. Related to the new background modeling is needed to overcome this problem. This paper proposes how to obtain an efficient background model that meets real requirements. As a background model, the Mixed-of-Gaussian Model (MOG) was adopted and refined with some improvements with the Region Growing method. Evaluation to measure the performance of the MOG algorithm and Region Growing by using a detection rate to calculate the number of right and wrong in the detection of moving objects.

Abstract
Sand casting is one of the oldest methods applied in foundries industry. However, this method has several disadvantages such as high consumptions of energy. It has an impact on total cost production per pieces. In other side, the problem of cost of quality need an appropriate approach to reduce this cost immediately. This study proposed the alternative sand casting process, CRIMSON (Constrained Rapid Induction Melting Single Shot Up-Casting), to investigate the differences between this methods. The result of this study was indicate clearly that CRIMSON sand casting has a lower total cost per pieces which is the result of lower energy consumption and no cost in sortation and rework because the process was in statistical control.
An Adaptive Approach to Controlling Parameters and Population Size of Evolutionary Algorithm
Authors: Muzid Syafiul 
Published: January 2020

AbstractEvolutionary algorithm (EA) is a part of evolutionary computing inspired by the theory of biological evolution. Evolutionary algorithms have three parameters that must be defined, namely population size, probability of crossing over, and probability of mutation. The absence of standard rules in setting the value of these parameters becomes a difficulty in utilizing evolutionary algorithms to solve optimization problems so that it can cause early convergence in obtaining local optimum values. This research was conducted to find a way to adjust the value of these parameters by using fuzzy logic to determine the probability of crossing and mutation probability and the method of determining population size based on the best fitness value. This method is called Population Resizing on Fitness Improvement Fuzzy Evolutionary Algorithm (PRoFIFEA). The testing of this method uses the problem of Traveling Salesman Problem (TSP) compared to the standard evolutionary algorithm method which states that the PRoFIFEA method is able to find a more optimal solution.

Authors: Zuev L B , Barannikova S A , Zharmukhambetova A M 
Published: January 2020

AbstractThe regularities of the inhomogeneous plastic deformation such as Lüders bands are considered at the yield plateau. It has been established that the Luder front has stick-slip motion under these conditions. Such a character of motion at the deformation front is associated with the inhomogeneous distributions of the components of the plastic distortion tensor. A plausible estimate of the oscillation frequency was obtained during the development of the Lüders front. The estimation of the spatial period (the length of the autowave of localized deformation) also corresponds to reality.

Authors: Maslov S V 
Published: January 2020

Abstract
The method for metal damage determining for the inner surfaces of power equipment exposed to the coolant with a rapidly changing temperature is considered. Due to the impossibility of deformations and temperatures direct measurement for the inner surface, a calculation-experimental algorithm is proposed based on processing the results of strain measurements obtained for the outer surface in geometrically homogeneous and non-uniform zones of the structure. To qualify the functions for changing stresses and temperatures on the inner surface, in this paper, it is proposed to use the algorithm based on solving inverse problems of mechanics. The recovered functions of the temperature stresses temporal variations for the interface zone of the pipeline and the nuclear power plant body are presented.

Plastic deformation hardening of iron-nickel alloys
Authors: Pakhomova S A 
Published: January 2020

AbstractThe purpose of the study is to determine the influence of the structural state of the surface layer on the possibility of enhancing the properties of heavy-loaded parts, including gear wheels, by plastic deformation. Plastic deformation was carried out by shot-blasting treatment. Since the behavior of the structure of the carburized layer of gear wheels is very complex, single-phase iron-nickel alloys were studied as model alloys. It is shown that the contact fatigue strength and other operational properties of parts can be improved if we apply shot-blasting treatment in optimal conditions. After the latter should be low-temperature tempering, causing strain aging. The positive effect of such complex processing is associated with the formation of a favorable substructure - a substructure of martensite with high resistance to local microplastic deformation.
Influence of heat treatment modes on the formation of structure and physical and mechanical properties of cast blanks from the aluminothermic alloys

Published: January 2020

Abstract
The production of aluminothermic alloys is accompanied by high temperatures of the reaction products, the control of which is difficult both by direct and indirect methods. Filling the metal into the mould without controlling the casting temperature provides a high gradient between the metal and the mould, which leads to the formation of quenching structures and, in some cases, structural heterogeneity of the blanks. To reduce the temperature of the reaction products, an introduction to the composition of mixtures of inert additives, which determine the change in the chemical composition of the alloys, is used. The removal of high internal stresses and the ordering of the structures of the experimental samples are carried out by using homogenizing annealing. Moreover, in typical structure characteristics of cast blanks, transformations occur, as well as the diffusion of individual chemical elements throughout the blank volume. The purpose of this work is to study the influence of the procedure of homogenizing annealing on the formation of the structure and physical and mechanical properties of aluminothermic cast blanks. This paper presents the results of the study of the effect of homogenizing annealing on the formation of a structure in iron-carbon alloy castings. Iron-carbon alloys were produced by means of a new casting technology – aluminothermy.

Abstract
Features of grows on true tension at elasto-plastic strains at static and cyclic loading of structuralmetal materials in connection with their structural state (hardening, softening) are considered in this article. The features of the use of strains and kinetic criterion connected with the bearing capacity of material estimated by extreme plasticity of plastic strains at the time of formation of a neck are shown. It is established that growth of true tension at quasistatic destruction is connected first of all with active accumulation of the residual strains. Methods of strains of nature of behavior of material are described (hardening, softening, stabilization) at cyclic elasto-plastic strains. When loading with the set scope of elasto-plastic strains (tough loading) significant change e tension is observed only in the first (hardening) and the last (softening) cycles. Significant changes in true tension it is observed and directly in loading cycles. It is important to consider the specified changes of true tension when modeling processes of elasto-plastic strains of structural materials and also at the solution of a question of extension of a resource of the designs which fulfilled the resource.
Damage accumulation in cyclically stable steel under low-cycle loading
Authors: Romanov A N , Filimonova N I 
Published: January 2020

Abstract
Abstarct. The contribution of variable plastic strains (hysteresis loop), unilaterally accumulated plastic and elastic strains in the total accumulated damage in the limiting case (macro-crack formation) under quasi-static fracture is shown on the basis of the deformation-kinetic criterion of fatigue failure of cyclically stable steel, when the accumulated plastic strain is equal to or commensurable with the strain of a single (static) fracture. It is shown that in the case of low-cycle failure, the main damaging fraction is introduced by the static component (unilaterally accumulated strain), the value of which decreases with the increase of the number of cycles to failure (reduced load amplitude). This increases the contribution of variable cyclic strain. The influence of elastic strain in the area of quasi-static fracture is negligible, and the calculation of durability in practical applications can be carried out without taking into account the damaging role of elastic strains.

Abstract
The effects of equal-channel angular pressing (ECAP) and rotary swaging (RS) on the change in strength properties during aging at 170 ° C of Al-Mg-Si alloys doped with Sc, Zr and Hf additions was studied. The methods of measuring hardness, electrical resistivity, testing mechanical properties, light and transmission electron microscopy were used. The higher hardening effect compared to the initial state was found in the alloys after ECAP than after RS, whereas the strength properties (tensile strength and yield strength) were higher for alloys subjected to RS than ECAP. Al-Mg-Si alloys with the combined additives of scandium with zirconium and scandium with hafnium showed practically the same values of hardness and strength properties at tensile testing during aging. The reason is in the identical nature of the decomposition of the supersaturated solid solution. It is determined by the sequence of precipitation of the strengthening phase Mg2Si and (Sc1-x, Zrx) Al3 and (Sc1-x, Hfx) Al3 dispersoids which impede the movement of dislocations both in alloys after deformation and after aging.
