Coil sensitivity encoding for fast MRI. In:

by Klaas P Pruessmann , Markus Weiger , Markus B Scheidegger , Peter Boesiger - Proceedings of the ISMRM 6th Annual Meeting, , 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

analysis of error propagation in creating the raw map: where ⍀ is a parameter reflecting the degree of smoothing, d x,y denotes the pixel value at position x,y of the denominator image used for preparing the raw map, and ⌽ x,y is an ''object indicator'' map: ⌽ x,y ϭ 1 where object

New Techniques for Geographic Routing

by Ben Wing, Ben Wing, Lup Leong, Lup Leong , 2006
"... As wireless sensor networks continue to grow in size, we are faced with the prospect of emerging wireless networks with hundreds or thousands of nodes. Geographic routing algorithms are a promising alternative to tradition ad hoc routing algorithms in this new domain for point-to-point routing, but ..."

As wireless sensor networks continue to grow in size, we are faced with the prospect of emerging wireless networks with hundreds or thousands of nodes. Geographic routing algorithms are a promising alternative to tradition ad hoc routing algorithms in this new domain for point-to-point routing, but deployments of such algorithms are currently uncommon because of some practical difficulties.

PROGRESS IN ATOMIC ABSORPTION SPECTROSCOPY EMPLOYING FLAME AND GRAPHITE CUVETTE TECHNIQUES

by B V L'vov
"... ABSTRACT A simplified theory of analytical signal formation for various methods of sample atomization is proposed which takes into account the nature of sample transfer through the analytical cell and instrumental distortions of the pulse shape. An analysis of the relationships obtained shows the e ..."

samples by the flame technique using electric heating. The proposed theory also permitted optimization of the conditions of cuvette measurement by the peak method, making it possible to achieve record low absolute detection limits (10-14 to 10-15 g) and to reduce random measurement error to two per cent

Implementation Analysis of adaptive Viterbi Decoder for High Speed

by P. Subhashini, D. R. Mahesh Varma, Y. David, Solomon Raju
"... The demand for high speed, low power and low cost for Viterbi decoding especially in wireless communication are always required. Thus this paper presents the design of an adaptive Viterbi decoder that uses survivor path with parameters for wireless communication in an attempt to reduce the power and ..."

errors. The design is optimized with respect to time, area and power and the netlist is generated. The netlist obtained after synthesis undergoes the physical design process. The synthesized circuits are placed and routed in the standard cell design environment and implemented on a Xilinx FPGA device.

Magnet: Robust and Efficient Collection through Control and Data Plane Integration

by unknown authors
"... Despite being a core networking primitive, collection protocols today often suffer from poor reliability (e.g., 70%) in practice, and heavily used protocols have never been evaluated in terms of communication efficiency. Using detailed experimental studies, we describe three challenges that cause ex ..."

existing collection protocols to have poor reliability and waste energy: inaccuracies in link estimation, link dynamics, and transient loops. In this paper we present Magnet, a robust, efficient, and hardware-independent collection protocol. Magnet uses three novel techniques to address these challenges

Advances in Computational Methods for X-Ray Optics III, 92090A; References

by F Zernike , M Stampanoni
"... Introduction and Objectives Transition metal concentrations in the central nervous system (CNS) are implicated in neurodegenerative diseases such as Alzheimer's, Parkinson's and Multiple Sclerosis. A common symptom of these diseases is demyelination, which is the degradation of the myelin ..."

. Mingyuan@bnl.gov In-situ characterization combining transmission electron microscopy (TEM) and X-ray imaging provides the capability to investigate materials under real reactions with multi-length scale, from atomic structure to micron size overview. In this work, we have designed an in-situ cell, which

Channel Division Multiple Access: The Access Solution for UWB Networks

by Raul De Lacerda, Dépt Electromagnetism (dre/lss, Aawatif Hayar, Casablanca Maroc
"... Abstract—In this paper we study a promising multiple access scheme entitled Channel Division Multiple Access (ChDMA). ChDMA was developed to cope with the particularities of low duty cycle Impulsive Radio Ultra Wideband systems (IR-UWB). The idea is based upon the fact that Channel Impulse Responses ..."
