Quantitative Methods & Information Systems
Acapacity market is a business-to-business exchange in which equally capable suppliers compete with one another to satisfy generic orders from diverse buyers. The market is asymmetric because the buyers can carry inventory of the products ordered but the suppliers cannot store their capacity.
We study zero-sum risk-sensitive stochastic differential games on the infinite horizon with discounted and ergodic payoff criteria. Under certain assumptions, we establish the existence of values and saddle-point equilibria. We obtain our results by studying the corresponding Hamilton-Jacobi-Isaacs equations.
In a sample of mRNA species counts, sequences without duplicates or with small numbers of copies are likely to carry information related to mutations or diseases and can be of great interest. However, in some situations, sequence abundance is unknown and sequencing the whole sample to find the rare sequences is not practically possible.
One possible way of risk management for an insurance company is to develop an early and appropriate alarm system before the possible ruin. The ruin is defined through the status of the aggregate risk process, which in turn is determined by premium accumulation as well as claim settlement outgo for the insurance company.
The paper presents and tests Dynamic Value at Risk (VaR) estimation procedures for equity index returns. Volatility clustering and leptokurtosis are well-documented characteristics of such time series. An ARMA (1, 1)-GARCH (1, 1) approach models the inherent autocorrelation and dynamic volatility. Fat-tailed behavior is modeled in two ways.
We develop a model to understand and describe the inherent behaviours and interactions of members over time through the medium of user-generated content (UGC) in an on-line community.
A stochastic model for assessing Chlamydia trachomatis transmission risk by using longitudinal observational data
Bacterium Chlamydia trachomatis causes genital chlamydia infection. Yet little is known about the efficiency of transmission of this organism. Ethical constraint against exposing healthy subjects to infected partners precludes the possibility of quantifying the risk of transmission through controlled experiments.
Through recent technical advances, multiple resources can be connected to provide a computing grid for processing computationally intensive applications. We build on an approach, termed sequential grid computing, that takes advantage of idle processing power by routing jobs that require lengthy processing through a sequence of processors.
Online retailing started in a big way in the late nineties and grew into a major business in the past decade to become a major strategy for many retail companies. A large number of retail companies maintain a brick and mortar outlets as well as online presence.
A fuzzy approach for component selection amongst different versions of alternatives for a Fault Tolerant modular software system
Software projects generally have to deal with producing and managing large and complex software products. As the functionality of computer operations become more essential and yet more critical, there is a great need for the development of modular software system.
