Blind image deconvolution consists in restoring a blurred and noisy image when the point spread function of the blurring system is not known a priori. This inverse problem is ill-posed and need prior information to obtain a satisfactory solution. Regularization methods, well known, for simple image deconvolution is not enough. Bayesian inference approach with appropriate priors on the image as ...

Localization algorithm based on the linear least square principle has the advantages of small amount of calculations, and attracts many researchers. In this paper, some algorithms based on linear least square estimation for single target localization are researched. We analyze the essence of these algorithms, give the specific estimation process and summarize the advantages and drawbacks of the...

We examine how firms adjusted their open innovation strategy in response to the 2008 global financial crisis. While previous research has analysed advantages, drawbacks, and methods of innovation, less is known about adjust major economic shocks. Guided by theories organisational learning behavioural theory firm, we impact demand shock on firm openness external knowledge. To test our hypotheses...

Yet, two classes of algorithms have been used in partial constraint satisfaction: local search methods and branch&bound search extended by the classical constraint-processing techniques like e.g. forward checking and backmarking. Both classes exhibit characteristic advantages and drawbacks. This article presents a novel approach for solving partial constraint satisfaction problems exhaustively ...

Intrusion Detection Systems (IDSs) are security tools widely used in computer networks. While they seem to be promising technologies, they pose some serious drawbacks: When utilized in large and high traffic networks, IDSs generate high volumes of low-level alerts which are hardly manageable. Accordingly, there emerged a recent track of security research, focused on alert correlation, which ext...

Despite the obvious advantages of anaerobic sludge digestion viz. sludge reduction and sustainable management, it has some drawbacks. In particular, anaerobic digestion produces a complex and unknown residue sludge which is difficult to treat and to dewater. Because dewatering mainly involves rheological solid characteristics, this paper focuses on the similarities between these residues with o...

Abstract We highlight a new paradox for the social evaluation of risk that bears on individual well-being rather than welfare, but has serious implications evaluation. The consists in tension between rationality, respect preferences, and principle informational parsimony excludes attitudes from assessment riskless situations. No criterion can satisfy these three principles. This impossibility r...
