Design of Experiment (DOE) is a widely used method for examining experiments especially in industrial production and robust design processes. This set statistical approaches which mathematical models are developed through experimental testing to estimate possible outputs given input values or parameters. The aims determine the main factors that affect results with smallest number studies. In th...

This work addresses an evolutionary algorithmic approach to reduce the surplus pieces in selective assembly increase success rates. A novel equal area amidst unequal bin numbers (EAUB) method is proposed for classifying parts of ball bearing by considering various tolerance ranges parts. The L16 orthogonal array used identifying effectiveness EAUB through varying number bins assembly. Because q...

Eklemeli imalat yöntemi, geleneksel yöntemleriyle üretimi zor ya da mümkün olmayan, karmaşık geometriye sahip parçaların üretiminde önemli iyileştirmeler sunmaktadır. Ancak, çıktı kalitesinin istenilen seviyede olup olmadığı sorusu güncelliğini korumaktadır. Dolayısıyla, optimum üretim parametrelerinin elde edilmesi kalitesini artırmak adına oldukça önemlidir. Bu çalışmada, Seçici Lazer Ergitme...

This research work investigates the two body wear behavior of natural fiber reinforced composites using a pin on disc test set-up. Natural fibers such as Polyalthia Longifolia, Mangifera Indica and Jute were used reinforcements with epoxy matrix. Four types 30% weight fraction fabricated hand layup compression molding technique. Taguchi experimental design L16 orthogonal array was considered. f...

Abstract This study aimed to investigate the tribological and microstructural characteristics of LM26 composites reinforced with silicon carbide evaluate their suitability for high-temperature applications. For sample fabrication, modified stir-casting method was optimized using a Taguchi L16 orthogonal array. The wear rate friction behavior were evaluated Taguchi's S/N ratio analysis. When SiC...

To explore the potential metabolites from rabeprazole sulfide, seven strains of filamentous fungi were screened for their biotransformation abilities. Among these strains, Cunninghamella blakesleeana 3.970 exhibited best result. Four different culture media in order to identify most optimal subsequent research. Single factors such as initial pH media, time, inoculation volume, and volume indivi...

Product Market Regulation, Firm Selection and Unemployment This paper analyzes the effect of Product Market Regulation (PMR) on unemployment in a search model with heterogeneous multiple-worker firms. In our setup, PMR modifies the distribution of firm productivities, thereby affecting the equilibrium rate of unemployment. We distinguish between PMR related to entry costs and PMR that generates...

The paper investigates structural change among the four-digit (SIC) industries of the U.S. manufacturing sector during 1958-96 within a distribution dynamics framework. Focus is on the transition density of the Markov process that characterizes the value added shares of the industries. This transition density is estimated nonparametrically as well as by maximum likelihood, in which case the fun...

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...

We have sequenced a previously uncharacterized region of the Bacillus subtilis S10 ribosomal protein gene cluster. The new segment includes genes for S10, L3, L4, L23, L2, S19, L22, S3, and part of L16. These B. subtilis genes map in the same order as the genes in the Escherichia coli S10 ribosomal protein operon. Two potential promoter sequences were identified, one approximately 200 bases and...
