A new efficient unsupervised feature selection method is proposed to handle transactional data. The proposed feature selection method introduces a new Data Distribution Factor (DDF) to select appropriate clusters. This method combines the compactness and separation together with a newly introduced concept of singleton item. This new feature selection method is computationally inexpensive and is...

This paper proposes a new approach to representing scalable hierarchical distributed multi-party protocols, and reasoning about their behavior. The established endpoint-to-endpoint message-passing abstraction provides little support for modeling distributed algorithms in hierarchical systems, in which the hierarchy and membership dynamically evolve. This paper explains how with our new Distribu...

The immersed boundary method (IBM) of Peskin (J. Comput. Phys., 1977), and derived forms such as the projection Taira Colonius 2007), have been useful for simulating flow physics in problems with moving interfaces on stationary grids. However, their interface treatment, these methods do not distinguish one side from other, but rather, apply motion constraint to both sides, associated force is a...

In this paper, two non-linear technologies are proposed based on weak disposability definitions: weak disposability with non-uniform abatement factors and new weak disposability. Both technologies are applied to Spanish airport systems and the existing technologies are modified. To remove the computational complexity of non-linear approaches, the linearization methods are proposed. Then, in ord...

Bohai Rim region is an important economic development area and a large carbon emission in China. It of great significance to explore the total factor energy efficiency its influencing factors for low transformation high-quality region. Based on framework, DDF-DEA model was used calculate efficiency, internal external differences were further analyzed. The determined by ML index method classical...

Abstract The planning, design, and maintenance of stormwater infrastructure must be informed by changing rainfall patterns due to climate change. However, there is little consensus on how future information should used, or uncertainties introduced use different methods datasets characterized managed. These exacerbate existing challenges using local municipal scales. Here we analyze major cities...

Physical states of the superstring can be described in light-cone gauge by acting with transverse bosonic α −n and fermionic q̄ ȧ −n operators on an SO(8)-covariant superfield where j, ȧ = 1 to 8. In the pure spinor formalism, these states are described in an SO(9,1)-covariant manner by the cohomology of the BRST charge Q = 1 2πi ∮ λdα. In this paper, a similarity transformation is found which s...

This paper describes a decentralized Bayesian approach to coordinating multiple autonomous sensor platforms searching for a single non-evading target. In this architecture, each decision maker builds an equivalent representation of the target state PDF through a Bayesian DDF network enabling them to coordinate their actions without exchanging any information about their plans. The advantage of ...

By numerically solving the nonlinear Schrodinger equation, we analyze pulse propagation through dispersion decreasing optical fibers (DDFs) in which the core radius varies along the length of the fiber; this in turn leads to a variation of dispersion as well as mode effective area along the length of the fiber. We calculate an optimum core radius profile required to create a local balance betwe...
