Friction is a very old and universal issue in all mechanical systems. Since friction is non-linear, it is an ever challenging problem. Several empirical nonlinear friction models have been proposed in the technical literature. This paper does not propose any new model but it presents a new, tensor product (TP) based representation of the existing friction models which is suitable for control de...

The sharing market includes the idle product by owner and firm’s new sharing. Companies participating in economy choose to withdraw from because it is always difficult make a profit, due heavy asset investment, but there no such worry for owners who do not need cost input. At same time, we have observed that products launched companies are meet rental needs of consumers. Based on above findings...

new product development (npd) is described in the literature as the transformation of a market opportunity into a product available for sale. in the automotive industry, within the context of iso/ts16949:2002 (the automotive quality management system international standard),  these related to the product realization process (prp) which consists of three main phases such as planning, implementat...

Software product line engineering (SPLE) is an emerging approach that enables variability management in software development. SPLE offers tremendous benefits, but lack of tool support becomes a barrier the adoption SPLE. Variability modules for Java (VMJ) implementation defined based on (VM) concept to VMJ combines system and design patterns are commonly used by developers. accompanied UML prof...

Software product lines comprise techniques to tailor a program by selecting features. Selected features translate into sequenced program transformations which extend a base program. However, a sequence translated from the user selection can be inefficient to execute. In this paper, we show how we optimize sequences of refactoring transformations to reduce the composition time for product line p...

The paper proposes to integrate performance analysis in the early phases of the model-driven development process for Software Product Lines (SPL). We start by adding generic performance annotations to the UML model representing the set of core reusable SPL assets. The annotations are generic and use the MARTE Profile recently adopted by OMG. A first model transformation realized in the Atlas Tr...

Recent published data show that transformation and sorption are key processes involved in the subsurface transport of TNT. The state-of-the-art understanding of TNT soil transformation and sorption phenomena is summarized below: There is unequivocal evidence of reductive transformation of TNT in soils. However, soil properties affecting TNT transformation are only partially understood. Edaphic ...
