the efficiency of three statistical models, ahp surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in chehel-chai watershed in golestan province, iran. in current study the hazard map was prepared according to the top model of landslide hazard map. chehel-chai watershed is located as one of go...

Although failure data are usually treated as being continuous, they may have been collected in a discrete manner, or in fact be discrete in nature. Reliability models with bathtub-shaped hazard rate are fundamental to the concepts of burn-in and maintenance, but how well do they incorporate discrete data? We explore discrete versions of the additive Weibull distribution, which has the twin virt...

This paper investigates the demand elasticity of search. We provide a new characterization of monotone hazard rate and of the first-order condition determining the optimal reservation price, and prove that the demand for information is elastic if the hazard rate function h for the distribution of offers is decreasing and inelastic if h is increasing.  2000 Elsevier Science S.A.

Pär Holmberg January 28, 2006 Abstract This paper derives a Supply Function Equilibrium (SFE) of a pay-as-bid auction (discriminatory auction), such as the balancing market for electric power in Britain. It is shown that a SFE always exists if the hazard rate of the perfectly inelastic demand is monotonically decreasing and marginal costs are non-decreasing. With demand following a Pareto distr...

In this work, we present a five-parameter life time distribution called Harris power Lomax (HPL)  which is obtained by convoluting the Harris-G and Power distribution. When compared to existing distributions, new exhibits very flexible probability functions; may be increasing, decreasing, J, reversed J shapes been observed for density hazard rate functions. The structural properties of...

A low complexity dynamic subcarrier and power allocation methodology for downlink communication in an OFDM-based multiuser environment is developed. The problem of maximizing overall capacity with constraints on total power consumption, bit error rate and data rate proportionality among users requiring different QOS specifications is formulated. Assuming perfect knowledge of the instantaneo...
