Association Rules in Data Mining: An Application on a Clothing and Accessory Specialty Store

Abstract: Retailers provide important functions that increase the value of the products and services they sell to consumers. Retailers value creating functions are providing assortment of products and services: breaking bulk, holding inventory, and providing services. For a long time, retail store managers have been interested in learning about within and cross-category purchase behavior of their customers, since valuable insights for designing marketing and/or targeted cross-selling programs can be derived. Especially, parallel to the development of information processing and communication technologies, it has become possible to transfer customers shopping information into databases with the help of barcode technology. Data mining is the technique presenting significant and useful information using of lots of data. Association rule mining is realized by using market basket analysis to discover relationships among items purchased by customers in transaction databases. In this study, association rules were estimated by using market basket analysis and taking support, confidence and lift measures into consideration. In the process of analysis, by using of data belonging to the year of 2012 from a clothing and accessory specialty store operating in the province of Osmaniye, a set of data related to 42.390 sales transactions including 9.000 different product kinds in 35 different product categories (SKU) were used. Analyses were carried out with the help of SPSS Clementine packet program and hence 25.470 rules were determined.

Modelling study on production cross sections of 111In radioisotopes used in nuclear medicine

Abstract: Radiopharmaceuticals are radioactive drugs used for diagnosis or treatment in a tracer quantity with no pharmacological action. The production of radiopharmaceuticals is carried out in the special research centers generally using by the cyclotron systems. Indium-111 is one of the most useful radioisotopes used in nuclear medicine. In this paper, we calculated the production cross sections of 111In radioisotope via 111–114Cd(p,xn) nuclear reactions up to 60 MeV energy. In the model calculations, ALICE/ASH, TALYS 1.6 and EMPIRE 3.2 Malta nuclear reaction code systems were used. The model calculation results were compared to the experimental literature data and TENDL-2014 (TALYS-based) data.

Calculations of Double Differential Deuteron Emission Cross Sections at 62 MeV Proton Induced Reactions

Abstract: In this study, double differential deuteron emission cross sections for 27Al, 54,56Fe, 197Au, 208Pb and 209Bi target nuclei have been calculated by the TALYS code at 62 MeV proton energy. The use of TALYS involved calculations by the pre-equilibrium exciton model and the Hauser–Feshbach model. The calculated double differential cross sections have been compared with the experimental data taken from the literature.

Palladium nanoparticles generated in situ used as catalysts in carbonylative cross-coupling in aqueous medium

Abstract: Pd NPs, obtained in situ from imidazole complexes Pd(im)2Cl2 (im = methylimidazole, butylimidazole), efficiently catalyze the carbonylative Suzuki coupling in water at 80 °C and 1 atm of CO. In the catalytic system, used without any additional ligands, differently substituted diaryl ketones were obtained with yields of up to 100% in 1 h. Under slightly modified conditions, Pd NPs catalyze the alkoxycarbonylation of iodobenzenes to esters with high yield.
