Development of an automated simulation environment for Body in White joining techniques

Parts in the joining station are usually arranged and clamped to result in an assembly that perfectly resembles the CAD0 construction. The perfect set-up is usually determined with the help of numerical optimization. In reality there are imperfections specific for each part, which are usually adjusted in the workshop manually. To do numerical optimization for each part is computationally expensive. Here the need for a more efficient Data mining analysis method arises. The present thesis investigates the metamodeling techniques in order to approximate the geometry response to the change of the joining station parameters. The aim is to provide the evaluation of the model by interpolating between the geometry and station set-up variations. The suitable regressions, which are able to deal with non-linear geometry behaviour, are selected with the help of the literature research. The theory behind the numerical simulation, regressions and sampling is studied to ensure the right choice of the metamodel. An automated simulation environment is programmed to assist with the creation of variation in geometry and joining station, numerical solution and analysis. The chosen regressions - Support Vector Regression and Kernel Ridge Regression - are tested on models of different complexity. The errors are evaluated to provide the quantitative measure of the quality of regressions. Possible improvements of the metamodels are studied, such as Latin Hypercube sampling techniques. The reduced complexity metamodels proved to provide a good approximation, while dealing well with non-linearities. On the other hand, it was shown that models with many design variables require improvement in sampling technique to provide better result within reasonable computational costs. At the same time, Latin Hypercube did not provide visible advancements in the tested cases. The Automated Simulation Environment and the tested metamodels are a base for the future implementation of an Artificial Neural Networks for defining the perfect set-up of Body in White joining stations for imperfect parts

A model of second language learning by means of developing the prognostic component of thinking

© Medwell Journals, 2015. The study discusses the development of students' prognostic component of thinking in foreign language learning and the issue of bilingualism and multilingualism in multicultural education. The researcher suggests a model of foreign language learning based on the development of prognostic abilities by identifying its structural and processional characteristics. The model can be used in university education to improve the effectiveness of learning. According to the analysis of speech and thinking activities conducted in bilingual environment, successful foreign language learning of undergraduates depends on the level of the development of their thinking prognostic component. A comparison of prognostic abilities in students with different levels of foreign language skills demonstrates that errors of probabilistic prognosis in speech are manifested in the course of constructing speech utterances and may cause inadequacy of a communicative situation. A high level of communicative anticipation development involves the ability to understand and evaluate the behavior of other people, predict their utterances and be ready to respond multi-variably, choosing the most productive way of interaction. A comparative analysis shows that successful second language learning requires a high level of prognostic abilities

Peculiarities of person's speech and thought activity in the context of multicultural education

The article discusses the necessity to develop organizational and pedagogical conditions of optimizing speech and thought activity taking into account individual speech experience of students. It also displays the problem of bilingualism and multilingualism in the context of multicultural education. The aim of the research is to identify peculiarities of the person's speech and thought activity in the context of bilingualism. The analysis of students' speech and thought activity demonstrates that the level of the speech and thought activity is connected with the bilingualism type and prediction component of thought. The latest is peeped in the ability to make a lingual guess, assess the linguistic probability of the word appearance and is based on the full analysis of cause-and-effect relations and the flexibility of thought while making speech assumptions. It has been determined that high level of prediction abilities is necessary for successful development of the person's speech activity. The necessity to develop students' speech and thought activity in the context of bilingualism within the educational process of higher school has been proved. © IDOSI Publications, 2014

Представлены результаты дисперсионного и корреляционного анализа, согласно которым качество образования дошкольников зависит от определенных показателей профессионального мастерства педагогов, влияющих на развитие игровой деятельности ребенка

Sediment from clarification facilities for wash water of stations using PolyDADMAX

Natural water treatment plants at surface water sources generate significant amounts of precipitation. The physical properties of sediments of washing waters of fast filters, clarifying water using the PolyDADMAX flocculant, were determined. A change in the specific filtration resistance during the measurement process was established, as well as the possibility of determining the physical properties of the sediment not only directly, but also indirectly. Various levels of correlation of physical properties among themselves are established
