The electric arc furnace operation at the Štore Steel company, one of largest flat spring steel producers in Europe, consists charging, melting, refining chemical composition, adjusting temperature, and tapping. Knowledge consumed energy within individual steps is essential. consumption during melting was analyzed including maintenance technological delays. In modeling consumption, 25 parameters were considered (e.g., coke, dolomite, quantity), tapping injected oxygen, carbon, limestone...

Abstract In this article we propose a new integrated genetic programming and algorithm approach to predict surface roughness in end-milling. Four independent variables, spindle speed, feed rate, depth of cut, vibrations, were measured. Those variables influence the dependent variable (i.e., roughness). On basis training data set, different models for developed by programming. The floating-point constants best model additionally optimized algorithm. Accuracy was proved on testing set. By...

The purpose of this pilot study was to gather information on the immediate and short-term effects relaxation training according Yoga In Daily Life ® (YIDL) system psychological distress breast cancer patients. 32 patients at Institute for Oncology Ljubljana were randomized experimental (N = 16) control group 16). Both groups received same standard physiotherapy 1 week, while additionally a sessions YIDL system. At discharge issued with audiocassette recordings containing similar instructions...

The 5′ untranslated region (UTR) of retroviruses contain structured replication motifs that impose barriers to efficient ribosome scanning. Two RNA structural facilitate translation initiation despite a complex UTR are internal entry site (IRES) and proximal post-transcriptional control element (PCE). Here, stringent protein analyses determined the spleen necrosis virus (SNV), reticuloendotheliosis A (REV-A) human T-cell leukemia type 1 (HTLV-1) exhibit PCE activity, but not IRES activity....

At discharge, experimental group issued audiocassette recordings containing instructions be practiced individually home an additional 3 weeks.The convenience sample 32 cancer recruited...

Because the proportion of working-age people in EU is shrinking, it necessary to help employers be able install various aids maintain health employees, especially very demanding manual jobs.Well-being thus becoming just as important cost reduction.One such area manto-goods order picking.The paper proposes genetic algorithms (GA) assist logistics managers deciding about most optimal pattern stacking items storage locations racks.During peak season, makes sense arrange terms minimum...

Abstract The optimal thermomechanical processing in steel industry is difficult because of the multiconstituent and multiphase character commercial steels, variety possible paths, plant specific equipment characteristics. This article shows successful implementation genetic programming approach for increasing furnace conveyor speed consequently productivity heat treatment soft annealing process. data (222 samples covering 24 different grades) on a speed, chemical composition (weight percent...

The paper proposes genetic programming (GP) to predict the bending capability of rolled titanzinc metal sheet. In this study ZnTiCu alloy with ∼ 0.1% Cu and Ti was used for production Three groups independent input variables were measured: (1) chemical composition during casting (percentage Cu, Ti, Fe), (2) parameters hot rolling (temperature ingot before rolling, time temperature plate after cooling), (3) cold sheet rolling). Therefore, nine (parameters) influence metal. On basis...

Abstract The purpose of this pilot study was to gather information on the immediate and short-term effects relaxation training according Yoga In Daily Life ® (YIDL ) system anxiety breast cancer patients. YIDL is a holistic being practised taught worldwide has been proven be highly effective in prevention treatment various diseases. aims establish physical, mental, spiritual, social health. Thirty-two patients at Institute for Oncology Ljubljana were randomized experimental (n=16) control...

Abstract Background One challenge a modern society faces is this: providing those vulnerable and ageing groups of adults who have intellectual disabilities with appropriate support for improving static dynamic balance. Balance crucial component physical fitness and, consequently, fall reduction prevention. The aim the present randomised controlled trial was to evaluate efficacy, after 16 weeks, that three different Special Olympics activity programmes had on balance in disabilities. Method A...

This article presents a cloud-based system for the on-line monitoring of tool conditions in end milling. The novelty this research is developed that connects IoT (Internet Things) platform cloud to machine and optical detection cutting chip size. takes care acquisition transfer signals regarding size application, where they are used as an indicator determination conditions. In addition, presented approach artificial intelligence integrated into platform, which monitors tool’s condition...

ABSTRACT This article compares genetic algorithm (GA) and programming (GP) for system modeling in metal forming. As an example, the radial stress distribution a cold-formed specimen (steel X6Cr13) was predicted by GA GP. First, cylindrical workpieces were forward extruded analyzed visioplasticity method. After each extrusion, values of independent variables (radial position measured node, axial coefficient friction) collected. These influence value dependent variable, stress. On basis...

Residual stresses are present in engineering components as an unintended consequence of manufacturing processes, but they also deliberately introduced to beneficial effect during surface procedures. Plasma nitriding is a process particular importance for forming tools and dies, giving significant advantages wear, fatigue resistance through the generation near-surface compressive residual stresses. A precise knowledge level distribution that exist necessary accurate design prediction...

Store Steel Ltd. is one of the biggest spring steel producers in Europe. Spring should have proper chemical composition and microstructure be without surface defects. Decarburization—that is, reduction carbon content—also influences quality. During regular production, data regarding rolled bars (width, rate, composition, total decarburization) heating furnace for billets before rolling (heating temperature, time, oxygen content) were monitored. On basis monitored data, a mathematical model...

Štore Steel Ltd. is a small flexible steel plant in Slovenia. In 2010, the new continuous rolling mill, which has technical capacity of 250,000 tons per year, was installed. The entailed corresponding reduction space, required an urgent relocation machinery. genetic algorithm used for optimal rearranging Two-dimensional or three-dimensional representation machines without any kind geometrical restrictions can be proposed algorithm. layout efficiency after machinery could increased by 58.1%,...
