This paper considers preferences over risky timed outcomes and proposes the weighted temporal utility (WTU) model which separates anticipated subjective evaluations of outcomes from attitudes toward psychological distance induced by risks and delays. Anticipating the subjective evaluation of an outcome requires the decision maker to project himself to the future and to imagine how much he will ...

Detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (WSNs). To address the problem of outlier detection in wireless sensor networks, in this paper we present a PCA-based centralized approach and a DPCA-based distributed energy-efficient approach for detecting outliers in sensed data in a WSN. The outliers in sensed data can be ca...

Most primal minimum cost network flow (MCNF) algorithms can be seen as variants on cancelling negative augmenting cycles. The analogous view of dual MCNF algorithms is that they cancel positive augmenting cuts. In a companion paper we show that if a dual algorithm chooses to cancel cuts which have the greatest rate of increase in dual objective value per arc, which are called maximum mean cuts,...

We describe a network implementation of the SUP-INF method of solving sets of inequalities that has advantages over previous implementations. The cost of symbolic manipulation is transferred to compile-time allowing speed up at run-time due to parallel evaluation. Further, allowing iteration in the network improves the competence of the method when working with non-linear expressions. We use th...

In the offline list update problem, we maintain an unsorted linear list used as a dictionary. Accessing the item at position i in the list costs i units. In order to reduce access cost, we are allowed to update the list at any time by transposing consecutive items at a cost of one unit. Given a sequence of requests one has to serve in turn, we are interested in the minimal cost needed to serve ...

This paper considers a Train Shunting problem which occurs in cargo train organizations: We have a locomotive travelling along a track segment and a collection of n cars, where each car has a source and a target. Whenever the train passes the source of a car, it needs to be added to the train, and on the target, the respective car needs to be removed. Any such operation at the end of the train ...

Abstract. We design experiments to jointly elicit risk and time preferences for the adult Danish population. We find that joint elicitation results in estimates of discount rates that are dramatically lower than those found in previous studies. Estimation of latent time preferences requires that one specify a theoretical structure to understand risk and time choices, but we show that our main r...

We consider an economic agent with dynamic preference over a set of uncertain monetary payoffs. We assume that the agent’s preferences are given by utility functions, which are updated in a time-consistent way as more information is becoming available. Our main result is that the agent’s indifference prices are time-consistent if and only if his preferences can be represented with utility funct...

risk management is one of the nine project management processes, which provides positive results and minimizes the probability and consequences of adverse effects in the project.  in this article a zero-one linear programming model with multiple objectives is used to characterize the potential risks. the proposed model has two main objectives. the first objective is the minimization of the expe...
