The purpose of this study was to explore the complex flow structure a novel active-type micromixer that based on concept of Wankle-type rotor. The characteristics of this micromixer are two folds; a rapid mixing of reagents in a limited space due to the generation of multiple vortices and a graduate increment in dynamic pressure as the mixed reagents is delivered to the output ports. Present mi...

the invention of higher tonnage steamships and the opening of the suez canal instead of the way of southern africa, created significant changes on commercial affairs of 19th century. the iranian southern ports, accessing to the open seas through the persian gulf, had benefited such development. this article is indirectly trying to analyze the impact of the suez canal on iranian ports on the bas...

Model-Driven Design (MDD) techniques can be used to design control software for cyber-physical systems, reducing the complexity of designing such software. Most MDD tools do not provide proper support to interact with the environment of the models, i.e. the actuators and sensors of a cyber-physical system, resulting in the models being sandboxed. So-called “Hardware Ports” are proposed in this ...

This paper describes a new architecture for a scalable multicast ATM switch from a few tens to thousands of input ports. The switch, called Abacus switch, has a nonblocking memoryless switch fabric followed by small switch modules at the output ports; the switch has input and output buuers. Cell replication, cell routing, output contention resolution, and cell addressing are all performed distr...

We are facing a growing user demand for ubiquitous Internet access. As a result, network ports are becoming common in public spaces within buildings such as lounges, conference rooms and lecture halls. This introduces the problem of protecting these public ports from unauthorized use. In this paper, we study the problem of access control for public network ports. We view this problem as a speci...

outers knit together the constituent networks of the global Internet, creating the illusion of a unified whole. While their primary role is to transfer packets from a set of input links to a set of output links, they must also deal with heterogeneous link technologies, provide scheduling support for differential service, and participate in complex distributed algorithms to generate globally coh...

Significant advantages of intermodal and containerized transport have increased the global interest to this mode of transportation. This growing interest is reflected in the annual volume of container cargo growth. However, the container transport inside Iran does not have a proper place. Comparing the count of containers entering and leaving ports with the statistics obtained from railway and ...

The paper deals with the implementation of security measures in small to medium developing countries. Based on Croatian experience, it examines possibilit ies for efficiently combining security measures that should be implemented in SOLAS ships and ISPS compliant ports with those appropriate to non-SOLAS ships and ports where measures defined in the ISPS Code are not mandatory. Finally, it exam...

In this paper, we investigate the uses of virtual channels and multiple communication ports to improve the performance of global communication algorithms for cycles and multi-dimensional toroidal meshes. We use a linear cost model to compare the performances of the best single-port algorithms for broadcasting, scattering, gossiping, and multi-scattering with algorithms that can use multiple por...

Three Port Converters are used for merging more than a single source in order to improve the power handling capability. Here the first two ports acts as the sources and the third port acts as the output or to the Load. The objective is combining the Wind Energy Systems with the Existing Three Port Converter System instead of a Battery Storage. The proposed system is simulated and verified using...
