Kernel spectral clustering is a model-based spectral clustering method formulated in a primal-dual framework. It has a powerful out-of-sample extension property and a model selection procedure based on the balanced line fit criterion. This paper is an improvement of a previous work which sparsified the kernel spectral clustering method using the line structure of the data projections in the eig...

Monte Carlo simulations and Wertheim’s thermodynamic perturbation theory (TPT) are used to predict the phase diagram percolation curve for simple two-dimensional rose model of water. In water, water molecules modelled as Lennard-Jones disks, with additional potentials orientation dependent pairwise interactions that mimic formation hydrogen bonds. Modifying both shape range a 3-petal function, ...

As a lesson learned, the readiness review process of SCAMPI appraisal is very complicated and effort and cost consuming for novice organizations who need to know their status of CMMI practices classification. In SCAMPI appraisal, the readiness review process is a single process that runs from start to the end. During the readiness review process, nobody collected database to improve the process...

Data on 657 lactation from 163 Maltese goat, collected over a 5-year period were analyzed by a mixed model to estimate the variance components for heritability. The considered lactation traits were: milk yield (MY) and lactation length (LL). Year, parity and type of birth (single or twin) were significant sources of variation for lactation length; on the other hand milk yield was significantly ...

the aim of this study is to evaluate the obstacles due to a dpsir model combined with fuzzy analytic hierarchy process technique. hence, to prioritize the responses regarding the driving forces, pressures, states and impacts, the hierarchy of the model is established. evaluations and prioritization of model results of urban transport situation in tehran have provided a number of necessary issue...

Abstract: Equipment maintenance is one of the core tasks in power system operations. The premise and foundation for maintenance is to establish a power equipment maintenance model, which should reflect all equipment states accurately including operation, inspection and maintenance. On the basis of the analysis of the traditional state diagram probability model, an improvement is put forward to ...
