A Case Study of Algorithm Implementation in Recon gurable Hardware and Software
We present a case study of implementation of a combinatorial search problem in both recon gurable hardware and software. The particular problem is the search for approximate solutions of overconstrained systems of equations over GF(2). The problem is of practical interest in cryptanalysis. We consider the e cient implementation of exhaustive search techniques to nd the best solutions of sets of...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولRobotic Recon for Human Exploration
Introduction Robotic reconnaissance has the potential to significantly improve scientific and technical return from lunar surface exp loration. In particular, robotic recon may increase crew productivity and reduce operational risk for exploration. However, additional research, development and field-testing is needed to mature robot and ground control systems, refine operational protocols, and ...
متن کاملA Reconstruction Algorithm for Helical Cone-Beam SPECT
Cone-beam SPECT provides improved sensitivity for imaging small organs like the brain and heart. However, current cone-beam tomography with the focal point traversing a planar orbit does not acquire sufficient data to give an accurate reconstruction. In this paper, we employ a data-acquisition method which obtains complete data for cone-beam SPECT by simultaneously rotating the gamma camera and...
متن کاملAlgorithm for image reconstruction in multi-slice helical CT.
Efforts are being made to develop a new type of CT system that can scan volumes over a large range within a short time with thin slice images. One of the most promising approaches is the combination of helical scanning with multi-slice CT, which involves several detector arrays stacked in the z direction. However, the algorithm for image reconstruction remains one of the biggest problems in mul...
