We present a problem dealing with transportation of live animals to slaughterhouses. The problem is taken from the Norwegian meat industry, and may be viewed as a vehicle routing problem extended with constraints to ensure a smooth production flow at the abattoir. In addition, several constraints to ensure animal welfare have to be met. These include duration limits for how long animals may sta...

This paper examines the feasibility of merging the results of retrieval runs on separate, autonomous document collections into an eeective combined result. In particular, we examine two collection fusion techniques that use the results of past queries to compute the number of documents to retrieve from each of a set of subcollections such that the total number of retrieved documents is equal to...

We introduce a first theory of price impact in the presence an interest rate term structure. explain how one can formulate instantaneous and transient on zero-coupon bonds with different maturities, including cross that is endogenous to connect introduced classic no-arbitrage for markets, showing be embedded pricing measure no arbitrage preserved. extend setup coupon-bearing further show implem...

To avoid the secondary pollution that inorganic corrosion inhibitor may cause in circulating cooling water, the bio-corrosion inhibition effect of lysozyme, catalase, lipase, and laccase, as the biologic inhibitors without the above problem, and the increased bio-corrosion inhibition effect of Ca+2 and Mg+2 are studied. An enzyme with corrosion properties was selected by rotary coupon test. The...

Asymptotic normality as well as some weak invariance principles for bonus sums and waiting times in an extended coupon collector's problem are considered and incorporated in the study of the asymptotic distribution theory of estimators of (finite) population totals in successive sub-sampling (or multistage sampling) with varying probabilities (without replacements). Some applications of these t...

Abstract We consider the problem of pricing in financial markets when agents do not have access to full information. The particular problem concerns the pricing of non traded or illiquid bonds on the basis of the observations of the yields of traded zero-coupon bonds. The approach being used gives an example of how stochastic filtering techniques, in particular the Kalman filter, can be usefull...

Three alternative approaches to the valuation of a defaultable coupon bond in an extended Merton’s model are given. Probabilistic approach yields a closed-form expression for the arbitrage price of this bond. A boundary value problem method is based on the concept of an CD-extended generator for Markov processes. The third approach relies on a recursive procedure method in which at every step a...

File swarming (or file sharing) is one of the most important applications in P2P networks. In this paper, we propose a stochastic framework to analyze a file swarming system under realistic setting: constraints in upload/download capacity, collaboration among peers and incentive for chunk exchange. We first extend the results in the coupon system [18] by providing a tighter performance bound. T...

In this paper we study American put options on zero-coupon bonds under the CIR model of short interest rates. The uniqueness of the optimal exercise boundary and the solution existence and uniqueness of a degenerate parabolic free boundary problem are established. Numerical examples are also presented to confirm theoretical results.
