Cyber-physical systems (CPSs) integrate heterogeneous and process sensor data using digital services. As the complexity of CPS increases, it becomes more challenging to efficiently formalize integrated multidomain views with flexible automated verification across entire lifecycle. This article illustrates a model-based engineering tool-chain support development an emphasis on parameter value se...

The nearly omnipresence of the Internet and the steady increase of wireless computing and mobile devices require highly dynamic adaptable distributed system architectures. Building such architectures needs a combination of key concepts from component technology and distributed systems. Mobile agents provide this combination. We use mobile agents as the building blocks of a component-based syste...

In this study, the salt weathering effects on engineering properties and weight loss potential of three types of granitoid rocks were investigated. Sodium and magnesium sulfates tests were performed on core and aggregate samples. The cyclic salt weathering tests on core samples were done up to 90 cycles, while these tests on aggregate samples were done up to 40 cycles. The results showed that d...

The uniaxial compressive strength (UCS) of intact rocks is an important geotechnical parameter required for designing geotechnical and mining engineering projects. Obtaining accurate estimates of the rock mass UCS parameter throughout a 3D geological model of the deposit is vital for determining optimum rock slope stability, designing new exploratory and blast boreholes, mine planning, optimizi...

1 Associate Professor of Mechanical Engineering and Corresponding Author Phone: (404) 894-9668; Fax: (404) 894-9342; Email: [email protected] ABSTRACT In this paper we propose a general method for making process parameter decisions in the development of a rapid manufacturing system. Given a level of demand, the designer can use our method to select the appropriate type of rapid prototyp...

There is an increased awareness of the benefits of modeling imprecision in engineering problems, but success is limited by two problems associated with the calculus of imprecision: (1) Solving equations for a parameter is difficult because the common operators of addition and multiplication lack true inverses. (2) The multiple occurrence of imprecise quantities in engineering functions can lead...

Multipath traffic engineering utilizes several multiple paths for transporting the traffic demand between source LSR and destination LSR. Using the multipath, we can effectively control the network resource utilization. If maximally disjoint multiple LSPs are found, the multipath traffic engineering can provide appropriate fault-tolerant routing. In this paper, we propose the fault-tolerant mul...
