Tabu Search -- Part I
, 1989
"... This paper presents the fundamental principles underlying tabu search as a strategy for combinatorial optimization problems. Tabu search has achieved impressive practical successes in applications ranging from scheduling and computer channel balancing to cluster analysis and space planning, and more ..."

of computational experience for a variety of applications. Part I1 of this study (to appear in a subsequent issue) examines more advanced considerations, applying the basic ideas to special settings and outlining a dynamic move structure to insure finiteness. Part I1 also describes tabu search methods for solving
Online Learning with Kernels
, 2003
"... Kernel based algorithms such as support vector machines have achieved considerable success in various problems in the batch setting where all of the training data is available in advance. Support vector machines combine the so-called kernel trick with the large margin idea. There has been little u ..."

A simple method for displaying the hydropathic character of a protein
- Journal of Molecular Biology
, 1982
"... A computer program that progressively evaluates the hydrophilicity and hydrophobicity of a protein along its amino acid sequence has been devised. For this purpose, a hydropathy scale has been composed wherein the hydrophilic and hydrophobic properties of each of the 20 amino acid side-chains is tak ..."

-chains is taken into consideration. The scale is based on an amalgam of experimental observations derived from the literature. The program uses a moving-segment approach that continuously determines the average hydropathy within a segment of predetermined length as it advances through the sequence
Choices, values and frames.
- American Psychologist,
, 1984
"... Making decisions is like speaking prose-people do it all the time, knowingly or unknowingly. It is hardly surprising, then, that the topic of decision making is shared by many disciplines, from mathematics and statistics, through economics and political science, to sociology and psychology. The stu ..."

. The tension between normative and descriptive considerations characterizes much of the study of judgment and choice. Analyses of decision making commonly distinguish risky and riskless choices. The paradigmatic example of decision under risk is the acceptability of a gamble that yields monetary outcomes
The Simple Economics of Basic Scientific Research
- Journal of Political Economy
, 1959
"... I begin this essay by reflecting on my early paper (Nelson, 1859), and Ken’s (Arrow, 1962), as period pieces. These papers certainly have been influential in shaping the discussion of science and technology policy over the last forty years, at least among economists, but at the time they were writte ..."

written, economists were just beginning to get into analysis of the key processes and institutions involved in technological advance. A lot has been learned since that time, and the discussion has become much more sophisticated. I will highlight two of those intellectual developments: the growing
From Sparse Solutions of Systems of Equations to Sparse Modeling of Signals and Images
, 2007
"... A full-rank matrix A ∈ IR n×m with n < m generates an underdetermined system of linear equations Ax = b having infinitely many solutions. Suppose we seek the sparsest solution, i.e., the one with the fewest nonzero entries: can it ever be unique? If so, when? As optimization of sparsity is combin ..."

of equations. Such problems have previously seemed, to many, intractable. There is considerable evidence that these problems often have sparse solutions. Hence, advances in finding sparse solutions to underdetermined systems energizes research on such signal and image processing problems – to striking effect
Tabu Search -- Part II
, 1990
"... This is the second half of a two part series devoted to the tabu search metastrategy for optimization problems. Part I introduced the fundamental ideas of tabu search as an approach for guiding other heuristics to overcome the limitations of local optimality, both in a deterministic and a probabilis ..."

refinements and more advanced aspects of tabu search. Following a brief review of notation, Part I1 introduces new dynamic strategies for managing tabu lists, allowing fuller exploitation of underlying evaluation functions. In turn, the elements of staged search and structured move sets are characterized

However, successful content-based image retrieval systems require the integration of the two. There is an urgent need to develop integration mechanisms to link the image ..."

Abstract—Spam over Internet Telephony as the distribution of unwanted voice messages over Voice over Internet Protocol networks is an upcoming threat. It is harder to prevent than e-mail spam since its content is not available before the victim is annoyed. This is even more difficult if the spam is sent directly to the victim’s user equipment, bypassing the proxies of the service provider. Hence, this messages cannot be filtered, since the proxies are no longer participating in the transaction. This article presents a pre-validation mechanism, which ensures a minimum level of trust about the caller. It assumes that a legal registered user does not send any spam, since his service provider will penalize him if he does so. Therefore, the pre-validation mechanism sends some requests to the presence server of the provider and the user equipment of the caller to validate their existence. This enables the knowledge to allow a call attempt of an unknown user. Index Terms—Communication system security; Telephone equipment; Telephony; Spam
