The relevance of this study is especially high today, because the success of electronic business depends primarily on the introduction of innovative projects based on the economic and mathematical modeling of the subjects of electronic business. The use of the probabilistic model for modeling the activity of the subject of electronic business is proposed to simulate the model of S. Patel and A. Schlizher, which is based on a simple probabilistic model and takes into account some psychological effects of consumer behavior when choosing goods in the market. In this model, the following effects are considered: the effect of minimizing damage, the effect of assessing the importance of qualities and properties, the effect of minimizing the distance to the average commodity. The research is based on the study of the work of scientists-economists, on the synthesis and complex analysis of domestic and foreign studies of consumer behavior in the context of e-commerce. Among the methods used in the study can be distinguished such as observation, analysis and synthesis, the method of modeling. In determining the probability of selecting a platform in this model, the utility function is used. Based on the probability transition matrix, a consumer choice model was developed between two e-commerce platforms. The use of this model for the companies' choice of platforms for the implementation of their activities, as well as for the evaluation of the activity of the Internet platforms in general, is proposed. The results of modeling are the forecast distribution of market share between competitors. During the research the following tasks were fulfilled: the state of the e-commerce market in Ukraine was studied; the behavior of the subject of e-business has been explored; statistical information has been collected and processed in relation to the research object; the model of behavior of Internet consumers with the help of the chosen model was constructed

El valor percibido en webs de social commerce: Efectos sobre la lealtad del consumidor.

El estudio del comportamiento del consumidor en webs de social commerce está en auge, debido al gran crecimiento del sector en los últimos años. A pesar de ello, su comprensión se encuentra en su infancia, debido a la multitud de factores influyentes. Esta investigación, a través de la metodología del estímulo-organismo-respuesta, estudia qué papel tiene el valor percibido (O) por el consumidor, mediante el análisis de dos de sus principales antecedentes (calidad del sistema y del servicio) (S), así como de sus efectos sobre la lealtad (R). Los resultados obtenidos a partir de la aplicación de la técnica PLS a una muestra de 272 consumidores habituales de estas webs ponen de manifiesto la gran importancia que la calidad de la web tiene en la generación de valor en el consumidor, así como el rol clave de éste sobre las intenciones del consumidor tanto para volver a comprar como para recomendar.Universidad de Málaga.

Effect of gap lenghts of sphere-sphere electrodes on air breakdown level under lightning impulse

Impinging jets are a best method of achieving particularly high heat transfer coefficient and are therefore employed in many engineering applications. In this study we seek to understand the mechanism of the distributed heat on the curve surface with the goal of identifying preferred methods to predicting jet performance. The goals that have been achieved in the numerical results displayed are determine the influence of impingement jet characteristics on thermal and flow field on a curve surface, determine the variation of Nusselt numbers (NuD) along the curve surface in order to understand the heat transfer characteristics and study the effect of position (in the center, in the mid and in the end) and angle (α=90°, 60° and 30°) of jet impingement on curve surface, different Reynolds numbers (ReD) in range of (5000, 6000, 7000, 8000 and 9000). The program, which was extracted results it is (GAMBIT 2.4.6) and (FLUENT 6.3), simulation is (2-D) in submerged jet flow and the continuity, momentum and energy equations were solved by means of a finite volume method (FVM). This study covers the effect of different Reynolds numbers (ReD) on average Nusselt numbers (Nuavg) and local Nusselt numbers (NuD). From the result, the average Nusselt numbers (Nuavg) increased with the increase of Reynolds numbers (ReD) for all cases, in comparison between different positions (center, mid and end), of nozzle on curve surface at angle (α=90°) the maximum value of average Nusselt numbers (Nuavg=388.3) is found when the nozzle locate in the end followed by the mid position and smallest value of average Nusselt numbers (Nuavg=182.25) in the center of curve surface. In case of slant angle (α=60º) the maximum value of average Nusselt numbers (Nuavg=387.47) is found when the nozzle locate in the end followed by the mid position and smallest value of average Nusselt numbers (Nuavg=308.3) in the center of curve surface
