Recent advances in dual band infrared focal plane technology now enable the design and testing of a dual infrared band snapshot imaging spectrometer, the first-ever of its kind. A review of proof of concept results from a dual-visible-band Computed Tomographic Imaging Spectrometer (CTIS) system is presented. The dual-visible system demonstrates that it is possible to reconstruct two spatially c...

We report the results of our study on the role of microfluidic infiltration technique in improving the coupling characteristics of dual-core photonic crystal fiber (PCF) couplers. Using the finite element method (FEM), we evaluate the effective mode area, dispersion and coupling parameters of an infiltrated dual-core PCF. We use these parameters to design a compact and reconfigurable coupler by...

This research is concerned with the design and analysis of a geothermal based multi-generation system by applying both conventional and advanced exergy and exergoeconomic concepts. The proposed energy system consists of a dual-organic Rankine cycle (ORC) to vaporize liquefied natural gas (LNG) and produce electricity. A proton exchange membrane(PEM) electrolyzer is employed to produce hydrogen ...

electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. the critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...

Tornadoes represent a unique natural hazard because of the very low probability of occurrence, short warning times (on the order of only a fewminutes), and the intense and destructive forces imposed on engineered and nonengineered buildings. The very low-probability/very high-consequence nature of a tornado strike makes designing for survival and reducing damage under typical financial constrai...

Abstract This paper proposes a relationship between design thinking and computational thinking. It describes as two prominent ways of understanding how people address problems. suggests that, currently, each is defined theorized in isolation from the other. A two-dimensional ontological space that think addressing problems proposed, based on orientation thinker towards problem solution generali...

Due to the deployment of large scale sensor networks, there has been a lot of interest in finding distributed methods for solving complex optimisation problems. Indeed, due to the absence of a central entity which would coordinate network sensor node operations, each node needs to operate using information of local nature only. Recently, Markov Random Fields (MRF) theory has been applied to pro...

In this paper, we look at power optimization issues under dual supply voltage environment, with the goal of optimizing power consumption due to interconnection and gate capaci-tances. Logic level synthesis is used as a good starting point for power reduction, while subsequent placement stage mod-iies or veriies logic level design by providing more accurate estimate of power dissipation. We try ...

Comparisons among different dual-VT design choices for a large on-chip cache with single-ended sensing show that the design using a dual-VT cell and low-VT peripheral circuits is the best, and provides 10% performance gain with 1.2x larger active leakage power, and 1.6% larger cell area compared to the best design using high-VT cells.

A novel design of Dual-Core Photonic Crystal Fiber (DC-PCF) with silica-air microstructures is proposed in this paper. Nonlinearity and confinement loss of DC-PCF are evaluated by using a Full-Vectorial Finite Element Method (FV-FEM) successfully. By optimizing the geometry of three ring DC-PCFs, a high nonlinearity (52w-1km-1) and low confinement loss (0.001dB/km) can be achieved at 1.55μm wav...
