An artificial neural network (ANN) model is developed for the analysis, simulation, and prediction of the austenite reversion in the thermo-mechanical treatment of 304L austenitic stainless steel. The results of the ANN model are in good agreement with the experimental data. The model is used to predict an appropriate annealing condition for austenite reversion through the martensite to austeni...

Model transformations are increasingly being incorporated in software development processes. However, as systems being developed with transformations grow in size and complexity, the performance of the transformations tends to degrade. In this paper we investigate the factors that have an impact on the execution performance of model transformations. We analyze the performance of three model tra...

Model transformation plays a central role in Model-Driven Engineering (MDE) and providing bidirectional transformation languages is a current challenge with important applications. Triple Graph Grammars (TGGs) are a formally founded, bidirectional model transformation language shown by numerous case studies to be quite promising and successful. Although TGGs provide adequate support for structu...

In model-driven development (MDD), numerous metamodels, models, and model transformations need to be taken into account. These MDD-based artifacts—although highly interdependent—are autonomously maintained. Changes in one artifact (e.g., in a model) are not automatically reflected in other dependent artifacts (e.g., in a model transformation). The barrier for a tight integration of MDD-based ar...

Despite good results, Model-Driven Engineering (MDE) has not been widely adopted in industry. According to studies by Staron and Mohaghegi [1], [2], the lack of tool support is one of the major reasons for this. Although MDE has existed for more than a decade now, tool support is still insufficient. An approach to overcome this limitation for model transformations, which are a key part of MDE, ...

cacl2 treatment followed by heat shock is the most common method for artificial transformation. here, the cells were transformed using cacl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. the bl21 strain of escherichia coli (e. coli) was being susceptible using cacl2 treatment. some cells were ...

background road traffic accidents and their related deaths have become a major concern, particularly in developing countries. iran has adopted a series of policies and interventions to control the high number of accidents occurring over the past few years. in this study we used a time series model to understand the trend of accidents, and ascertain the viability of applying arima models on data...

In this paper, a geometric interpretation is provided of a new rational Landen transformation. The convergence of its iterates is also established.
