As field programmable gate array (FPGA) technology has steadily improved, FPGAs have become viable alternatives to other technology implementations for high-speed classes of digital signal processing (DSP) applications. In particular , radar front-end signal processing, an application formerly dominated by custom very large scale integration (VLSI) chips,… (More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract The ability afforded by microfluidics to observe the behaviors of microbes in highly controlled and confined microenvironments, across scales from a single cell to mixed communities, has significantly contributed to expand the… (More)
The Convective Weather Avoidance Model (CWAM) translates gridded, deterministic weather observations and forecasts into Weather Avoidance Fields (WAF). The WAF gives the probability, at each point in the grid, that a pilot will choose to deviate around convective weather at that location. CWAM have been developed and validated for en route, high altitude,… (More)
This paper focuses on the enhancement of the practical performance of an algorithm and data structures. It provides a way to achieve the effect on performance parameters of operating system. The proposed work has been done about the performance of a number crunching program (Matrix Multiplication) by varying the swap area at run time. We feed a C program as… (More)

Integrated-optic, astronomical, two-beam and three-beam, interferometric combiners have been designed and fabricated for operation in the L band (3 µm – 4 µm) for the first time. The devices have been realized in titanium-indiffused, x-cut lithium niobate substrates, and on-chip electro-optic fringe scanning has been demonstrated. White light fringes were… (More)
