Abstract: Rapid prototyping and additive manufacturing through 3D printing has significantly impacted business, industrial, and research activities as a rapidly emerging technology whose significance continues to grow. This new technology has been shown to lower the manufacturing costs in a wide array of applications that range in diversity from manufacturing nuclear power plant components to multi materials, and fabricating tissues and organs for human bodies to carbon fiber reinforced parts at unprecedented rates for private jets . The investigation of several heated platforms under operating conditions forms the basis for this paper from which the thermal coefficients of each product are experimentally derived. From this testing and derivation, intriguing observations regarding each platforms performance is presented. read more... read less...

Abstract: This paper presents a new methodology to master models transformation from CIM to PIM in accord with MDA approach. Our improved approach is founded on creation a good CIM level, through well-chosen rules, for facilitating models transformation to PIM level. However, we establish a rich PIM models via use case diagram, state diagram, class and package diagram. Next, we describe a set of transformation rules to ensure a semi-automatic transformation from CIM to PIM. Our method conform MDA approach by taking into consideration the business dimension in the CIM level, since, we present this level by using activity diagram who is a standard of business process modeling. Nevertheless, we use UML into PIM in our proposal, because UML is recommended by MDA in this level. read more... read less...

Abstract: This paper is aimed towards studying, compiling, and analyzing the recent advances and risks of the current ambient technology that is present in modern day cars. The progression of sophisticated technologies inside cars make them an even more comfortable and entertaining place to be in especially during commutes to work, but recent security threats and distractions have been uncovered with the upsurge usage of new technologies. The future of car’s interfaces is an issue since driverless cars are taking the scene by storm. This study also includes a survey that senses the people’s use of car technologies when driving. read more... read less...

Abstract: The process-oriented design and implementation of concurrent systems have important advantages. However, it is challenging to verify the consistency of process communications between the design and the implementation. To deal with such a challenge, we construct a formal framework for designing, implementing and verifying the consistency of process communications. In this framework, we use Failures in Communicating Sequential Processes (CSP), Erasmus and Category Theory as the foundation. The framework is illustrated by using a running example. Several algorithms are designed for constructing categorical structures in the framework. read more... read less...

Abstract: In this paper an attempt has been made to provide a new global evaluation approach of a specified software quality model extracted from a generic software quality model using an instantiation procedure. The evaluation is based on data extracted from an ambient distributed system composed of fusion and fission agents connected to input/output services. These data are linked to the appropriate metrics of our software quality model and we use quality factors stated in ISO standards and different models of researchers represented under an ontology. We use equivalent relations to link criteria that have the same meaning and fuzzy logic approach to evaluate the entire software quality model. Our work presents the following contributions: (i) creating a generic software quality model based on several existing software quality standards and formalized under ontology concepts (ii) proposing an instantiation algorithm to extract specified software quality model from a generic software quality models (iii) proposing a new global evaluation approach of the specified software quality model using two processes, the first one executes metrics related to sensors data and the second one uses the result of the first process using fuzzy logic approach evaluating the entire specified software quality model and end up with a final numerical result (iv) adding the variability of metric variables algorithm to determine the impact of a possible variation of one criterion on others and avoid their penalization. This can help to conduct a trade-off-analysis in the proposed quality evaluation approach. read more... read less...
