This paper is concerned with the problem of selecting a suitable bandwidth for the presmoothed density estimator from right censored data. An asymptotic expression for the mean integrated squared error (MISE) of this estimator is given, and the smoothing parameters minimizing it are proved to be consistent approximations of the MISE bandwidths. As consequence, a bandwidth selector based on plug...

Dimensional analysis under linguistic Pythagorean fuzzy set (DA-LPFS) is a technique to handle qualitative (intangible) as well the interactions between criteria, by combining dimensional (DA) and (PFS) with variables. In this paper, novel DA method proposed for LPFSs based in PFS extension, order consider mutual relationship among criteria (fuzzy) quantitative (crisp) information usually invol...

Annihilation or reduction of each kind of noise blended in correct data signals is a field that has attracted many researchers. It is a fact that fuzzy theory presents full capability in this field. Fuzzy filters are often strong in smoothing corrupted signals, whereas they have simple structures. In this paper, a new powerful yet simple fuzzy procedure is introduced for sharpness reduction in ...

This paper reckons that evidence of information technology (IT) business value can be found by examining how IT can help in improving effectiveness at the organizational level, i.e. IT-enabled organizational effectiveness. Using this as a point of departure, a questionnaire survey was conducted to collect responses from managing directors and chief executive officers of 147 enterprise resource ...

This paper deals with approximations of maximum independent sets in non-uniform hypergraphs of low degree. We obtain the first performance ratio that is sublinear in terms of the maximum or average degree of the hypergraph. We extend this to the weighted case and give a O(D̄ log log D̄/ log D̄) bound, where D̄ is the average weighted degree in a hypergraph, matching the best bounds known for the sp...

Findings from 2 pivotal government-funded studies of comparative antipsychotic effectiveness undermine assumptions about the marked superiority of the more expensive second-generation "atypical" medications in comparison to the less expensive first-generation "typical" drugs. Because this assumption was the basis for the almost universal recommendation that these newer antipsychotics be used pr...

This paper highlights the growing importance towards supporting Chinese Small to Medium sized Enterprises (SMEs) in adopting pro-active and collaborative behaviors that stimulate sustainability initiatives. Equating 90% of enterprises country contributing 60% nation’s gross domestic product (GDP), China’s SMEs are recognized for their willingness engage change, raising potential exploring embar...

Being inspired by Kaplan’s proposal for simulating chiral fermions on a lattice, we examine the continuum analog of his domain-wall construction for two-dimensional chiral Schwinger models. Adopting slightly unusual dimensional regularization, we explicitly evaluate the one-loop effective action in the limit that the domain-wall mass goes to infinity. For anomaly-free cases, the effective actio...
