Habitat-selection analysis lacks an appropriate measure of the ecological significance of the statistical estimates-a practical interpretation of the magnitude of the selection coefficients. There is a need for a standard approach that allows relating the strength of selection to a change in habitat conditions across space, a quantification of the estimated effect size that can be compared both...

in this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition petri nets. the mobile agent system contains two mobile agents called dca and una. it sends out agents to update antivirus on client computers in a network. each agent takes on a specified responsibility. first, dca roams through the network and check the last d...

Feature selection plays an important role in many machine learning and data mining applications. In this paper, we propose to use L2,p norm for feature selection with emphasis on small p. As p → 0, feature selection becomes discrete feature selection problem. We provide two algorithms, proximal gradient algorithm and rankone update algorithm, which is more efficient at large regularization λ. W...

productivity shocks are one of the most important factors that influence the firms ‘ decisions on he optimal consumption of production inputs. unobservable productivity shocks create selection and simultaneity problems causing biased estimates of production function by ordinary least squares. however, to estimate coefficients associated with production function by levinsohn and petrin technique...

We propose a mathematical framework for natural selection in finite populations. Traditionally, many of the selection-based processes used to describe cultural and genetic evolution (such as imitation and birth-death models) have been studied on a case-by-case basis. Over time, these models have grown in sophistication to include population structure, differing phenotypes, and various forms of ...

This paper presents a novel multipath energy aware routing for wireless ad hoc network. A deep analysis of different routing metrics such as MBCR, MMBCR and MDR have been led out and the Minimum Drain Rate metric has been selected as energy metric to integrate in the Multipath DSR protocol. Performance comparison with an energy efficient DSR (DSR-MDR) has been presented showing the benefits of ...

Wenbo Zong STMicroelectronics Asia Pacific Singapore Large-scale wargame simulations may involve tens of thousands of entities and generally run on distributed simulation nodes. An important issue in constructing these applications is to reduce the amount of data transmitted among the distributed simulation nodes so that the network and the simulation nodes will not be flooded by the state upda...

The decomposition of the tensor product of a positive and a negative discrete series representation of the Lie algebra su(1, 1) is a direct integral over the principal unitary series representations. In the decomposition discrete terms can occur, and the discrete terms are a finite number of discrete series representations or one complementary series representation. The interpretation of Meixne...
