A semi-analytical model that couples a model outside the borehole with one inside the borehole is proposed. To examine the effect of temperature rise in the soil surrounding a vertical ground heat exchanger on the performance of an associated ground heat pump, the heat pump model should be coupled to the model inside the borehole and the conduction heat transfer model outside the borehole. The running...
The paper proposes a scalable wavelength-switched optical NoC, named as SWS-ONoC. The proposed architecture is built upon a novel all-optical router which passively routes optical data streams based on their wavelengths. Utilizing wavelength routing method, SWS-ONoC eliminates electrical transactions for optical resource reservation and hence, reduces latency and area overheads of the electrical units...
This paper proposes a novel all-optical router as a building block for a scalable wavelength-switched optical NoC. The proposed optical router, named as AOR, performs passive routing of optical data streams based on their wavelengths. Utilizing wavelength routing method, AOR eliminates the need for electrical resource reservation and the corresponding latency and area overheads. Taking advantage of...
We propose a new architecture for on-chip routing of optical packets. The proposed infrastructure, referred to as CONoC, facilitates the development of an all-optical on-chip network and alleviates the role of electrical NoCs. As the first step for designing an all-optical NoC, CONoC resolves packet congestions optically and does not use electrical methods. Utilizing wavelength routing method, wavelength...
Network-on-chip (NoC) is a precious approach to handle huge number of transistors by virtue of technology scaling to lower than 50 nm. Virtual channels have been introduced in order to improve the performance according to a timing multiplexing concept in each physical channel. The incremental effect of virtual channels on power consumption has been shown in literatures. The issue of power saving has...
Power dissipation, energy consumption of CUT and also number of required test vectors for obtaining predetermined fault coverage are the most important criteria used for evaluating the quality of a test pattern generator (TPG). In this paper, we analyze LFSR's flexibility in improving these evaluation criteria for TPG. Usually, we are interested in considering these different criteria simultaneously,...
Technology scaling increases clock rates and die sizes; therefore, power dissipation is predicted to soon become the key limiting factor on the performance of single-chip designs. NoC as an efficient and scalable on-chip communication architecture for SoC architectures, enables integration of a large number of computational and storage blocks on a single chip. Since different applications impose different...

NoC is an efficient on-chip communication architecture for SoC architectures. It enables integration of a large number of computational and storage blocks on a single chip. NoCs have tackled the SoCs disadvantages and are scalable. In this paper, we compare two popular NoC topologies, i.e., mesh and torus, in terms of different figures of merit e.g., latency, power consumption, and power/throughput...
Real-time video transmission is considered as an important means for information distribution. One major application of it is e-learning, which requires real-time video processing and transmission. On the other hand, the process of cut detection is a fundamental component in automatic video browsing, indexing, searching, retrieval, and archiving. This paper introduces a new video cut detection technique...
