Validation of VHDL descriptions at the early phases of the microelectronic design is one of the most time consuming task design. This paper presents a test vector generation method for behavioral VHDL design. This method analyzes control and dependence flow of VHDL program. We use the cyclomatic complexity, that is a software metric based on a graph associated with the control part of software:...

Biologically inspired sensor-designs are investigated as a possible path to surpass the performance of more traditionally engineered designs. Inspired by crickets, artificial hair sensors have shown the ability to detect minute flow signals. This paper addresses developments in the design, fabrication, interfacing and characterization of biomimetic hair flow-sensors towards sensitive high-densi...

This paper presents a model for rural road network design that involves two objectives: maximize all season road connectivity among villages in a region and maximize route efficiency, while allocating a fix budget among a number of possible road projects. The problem is modeled as a bicriterion optimization problem and solved heuristically through a greedy randomized adaptive search procedure (...

one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...

Wireless Mesh Networks (WMNs) have gained a lot of attention recently. Many efforts are made to design proper routing protocols for WMNs. Existing multi-radio multichannel routing protocols utilize only one path for transmission, and some multi-path routing protocols consider only single channel situation, in which multi-path routing won‘t improve end-to-end throughput efficiently. In our paper...

Service restorability is a key requirement in optical networks. This means that when wavelength paths are established, both a primary path and a secondary disjoint path have to be set-up, with the secondary path being used for service restoration upon primary path failure. The secondary path may possibly be shared for efficiency. The need for secondary paths imposed by the restorability require...

A linear arrangement problem, called the minmax mincut problem, emerging from circuit design is investigated. Its input is a series-parallel directed hypergraph (SPDH), and the output is a linear arrangement (and a layout). The primary objective is to minimize the longest path, and the secondary objective is to minimize the cutwidth. It is shown that cutwidth D, subject to longest path minimiza...

Since the early 1980s, CAPP has been expected to bridge the gap between CAD and CAM. Though numerous research works on CAPP have been reported, it is not easy to ®nd a commercial CAPP system applicable to complicated objects with freeform shapes such as mold and die. The dependency on CAM system is holding one leg of CAPP, while the complexity of the solution space in freeform shape machining h...

We consider off-line versions of path provisioning and path protection problems for general circuit switched networks. Both problems deal with a given network topology and a list of integral demand flows. The objective is to route the flows and to allocate the bandwidth in a way that minimizes the total amount of bandwidth used for working and protection paths. We consider path-based protection...
