Five misunderstandings about case-study research

by Bent Flyvbjerg - Qualitative Inquiry , 2006
"... When I first became interested in in-depth case-study research, I was trying to understand how power and rationality shape each other and form the urban environments in which we live (Flyvbjerg, 1998). It was clear to me that in order to understand a complex issue like this, in-depth case-study rese ..."

A comparison of string distance metrics for name-matching tasks

by William W. Cohen, Pradeep Ravikumar, Stephen E. Fienberg , 2003
"... Using an open-source, Java toolkit of name-matching methods, we experimentally compare string distance metrics on the task of matching entity names. We investigate a number of different metrics proposed by different communities, including edit-distance metrics, fast heuristic string comparators, tok ..."

, token-based distance metrics, and hybrid methods. Overall, the best-performing method is a hybrid scheme combining a TFIDF weighting scheme, which is widely used in information retrieval, with the Jaro-Winkler string-distance scheme, which was developed in the probabilistic record linkage community.

Channel Assignment Schemes for Cellular Mobile Telecommunication Systems

by I. Katzela, M. Naghshineh - IEEE Personal Communications , 1996
"... This paper provides a detailed discussion of wireless resource and channel allocation schemes. We provide a survey of a large number of published papers in the area of fixed, dynamic and hybrid allocation schemes and compare their trade-offs in terms of complexity and performance. We also investigat ..."

Theory for the development of neuron selectivity: orientation specificity and binocular interaction in visual cortex

by Elie L. Bienenstock, Leon N Cooper, Paul W. Munro - J. Neurosci , 1982
"... The development of stimulus selectivity in the primary sensory cortex of higher vertebrates is considered in a general mathematical framework. A synaptic evolution scheme of a new kind is proposed in which incoming patterns rather than converging afferents compete. The change in the efficacy of a gi ..."

environment. One does not require nonlinearity of the neuron’s integrative power nor does one need to assume any particular form for intracortical circuitry. This is first illustrated in simple cases, e.g., when the environment consists of only two different stimuli presented alternately in a random manner

Nimrod/G: An architecture for a resource management and scheduling system in a global computational Grid

by Rajkumar Buyya, David Abramson, Jonathan Giddy - PROCEEDINGS OF THE 4TH INTERNATIONAL CONFERENCE ON HIGH PERFORMANCE COMPUTING IN ASIA-PACIFIC REGION (HPC ASIA 2000) , 2000
"... Abstract- The availability of powerful microprocessors and high-speed networks as commodity components has enabled high performance computing on distributed systems (wide-area cluster computing). In this environment, as the resources are usually distributed geographically at various levels (departme ..."

Multiuser OFDM with Adaptive Subcarrier, Bit, and Power Allocation

by Cheong Yui Wong, Roger S. Cheng, Khaled Ben Letaief , Ross D. Murch - IEEE JOURNAL ON SELECTED AREAS OF COMMUNICATIONS , 1999
"... Multiuser orthogonal frequency division multiplexing (OFDM) with adaptive multiuser subcarrier allocation and adaptive modulation is considered. Assuming knowledge of the instantaneous channel gains for all users, we propose a multiuser OFDM subcarrier, bit, and power allocation algorithm to minimiz ..."

to minimize the total transmit power. This is done by assigning each user a set of subcarriers and by determining the number of bits and the transmit power level for each subcarrier. We obtain the performance of our proposed algorithm in a multiuser frequency selective fading environment for various time

Kawa|compiling dynamic languages to the Java VM

by Per Bothner - In Proceedings of the USENIX Technical Conference, FREENIX Track , 1998
"... Many are interested in Java for its portable bytecodes and extensive libraries, but prefer a different language, especially for scripting. People have implemented other languages using an interpreter (which is slow), or by translating into Java source (with poor responsiveness for eval). Kawa uses a ..."

A new routing protocol for reconfigurable wireless networks

by Zygmunt J Haas - Proceedings of the IEEE International Conference on Universal Personal Communications (ICUPC , 1997
"... ABSTRACT: In this paper, we propose a new routing protocol, the Zone Routing Protocol (ZRP), for the Reconfigurable Wireless Networks, a large scale, highly mobile ad-hoc networking environment. The novelty of the ZRP protocol is that it is applicable to large Plat-routed networks. Furthermore, thr ..."
Abstract - Cited by 318 (5 self) - Add to MetaCart
, through the use of the zone radius parameter, the scheme exhibits adjustable hybrid behavior of proactive and reactive routing schemes. We evaluate the performance of the protocol, showing the reduction in the number of control messages, as compared with other reactive schemes, such as flooding.

A Vector-Perturbation technique for Near-Capacity . . .

by Christian B. Peel, Bertrand M. Hochwald, A. Lee Swindlehurst - IEEE TRANS. COMMUN , 2005
"... Recent theoretical results describing the sum capacity when using multiple antennas to communicate with multiple users in a known rich scattering environment have not yet been followed with practical transmission schemes that achieve this capacity. We introduce a simple encoding algorithm that achi ..."
