Risk measures and dependencies of risks.

In the last few years the properties of risk measures that can be considered as suiting 'best practice' rules in insurance have been studied extensively in the actuarial literature. In Artzner (1999) so-called coherency axioms were proposed to be satisfied for risk measures that are used for providing capital requirements. On the other hand Goovaerts et al. (2003a), (2003b),(2003c) argue that the choice of appropriate set of axioms should depend on the axiomatic 'situation at hand'. In this contribution, we show that so-called concave distortion risk measures are not always consistent with some well-known dependency measures such as Pearson's r, Spearman's p and Kendall's T, i.e. higher dependency between random variables does not necessary lead to higher risk measure of corresponding sums. We also test numerically to what extend risk measures are consistent with certain dependency measures and how stable the consistency level is for different one-parametric families of distortion risk measures.Actuarial; Choice; Consistency; Dependency; Distortion risk measures; Insurance; Premium principle; Random variables; Requirements; Research; Risk; Risk measure; Rules; Variables;

Sensor Selection Based on Generalized Information Gain for Target Tracking in Large Sensor Networks

In this paper, sensor selection problems for target tracking in large sensor networks with linear equality or inequality constraints are considered. First, we derive an equivalent Kalman filter for sensor selection, i.e., generalized information filter. Then, under a regularity condition, we prove that the multistage look-ahead policy that minimizes either the final or the average estimation error covariances of next multiple time steps is equivalent to a myopic sensor selection policy that maximizes the trace of the generalized information gain at each time step. Moreover, when the measurement noises are uncorrelated between sensors, the optimal solution can be obtained analytically for sensor selection when constraints are temporally separable. When constraints are temporally inseparable, sensor selections can be obtained by approximately solving a linear programming problem so that the sensor selection problem for a large sensor network can be dealt with quickly. Although there is no guarantee that the gap between the performance of the chosen subset and the performance bound is always small, numerical examples suggest that the algorithm is near-optimal in many cases. Finally, when the measurement noises are correlated between sensors, the sensor selection problem with temporally inseparable constraints can be relaxed to a Boolean quadratic programming problem which can be efficiently solved by a Gaussian randomization procedure along with solving a semi-definite programming problem. Numerical examples show that the proposed method is much better than the method that ignores dependence of noises.Comment: 38 pages, 14 figures, submitted to Journa

Why do masterplans fail?

Planning systems are in general addressed to make spatial projects conform to a plan, by assigning use rights in land through legally binding zoning maps and implementation rules, as it was possible to predict and impose sequences of actions and reactions in the realm of urban development. The cultural ideals of hierarchy and of dirigisme, based on the assumption that the State is the keeper of the collective interest, lie at the root of such ‘conforming' setting of modern planning systems. Neither the reiterated evidence of failure nor the acknowledgment that collective interest is usually the primary victim of planning ineffectiveness have led to conceive true alternatives so far. However, the exception of few countries where plans are non-binding and public authorities can evaluate which specific development projects are deserving new land use rights (the UK is one rare but prominent example), on the one hand, and the increasing experience of EU urban and spatial development programmes implying responsible evaluation mechanisms for co-funding projects, on the other, might let reflect about a possible model of ‘performing' planning syste

The Thesis ends with a technical-economic assessment.

Models for interrupted monitoring of a stochastic process

As computers are added to the cockpit, the pilot's job is changing from of manually flying the aircraft, to one of supervising computers which are doing navigation, guidance and energy management calculations as well as automatically flying the aircraft. In this supervisorial role the pilot must divide his attention between monitoring the aircraft's performance and giving commands to the computer. Normative strategies are developed for tasks where the pilot must interrupt his monitoring of a stochastic process in order to attend to other duties. Results are given as to how characteristics of the stochastic process and the other tasks affect the optimal strategies
