Air pollution are basically the foreign material in the air—can be manmade or occur naturally, and are concentrated where people are concentrated. Pollution is injurious to health and its prevention places an economic burden on the citizen. Further emission reductions from automobiles, and transportation measures and programs will be more difficult to accomplish, but the challenge has been pres...

Quartz is a human carcinogen and a causative agent of silicosis. Exposure levels often exceed exposure limits in the construction industry. The need for effective control measures is high, but the complex structure of the construction industry, the variability in sources of exposure and the frequent changes of worksite makes it difficult to implement even simple and potentially effective contro...

We study a class of robust, or worst case scenario, optimal control problems for jump diffusions. The scenario is represented by a probability measure equivalent to the initial probability law. We show that if there exists a control that annihilates the noise coefficients in the state equation and a scenario which is an equivalent martingale measure for a specific process which is related to th...

Using a recently developed microscopic traffic model, we simulate how speed limits, on-ramp controls, and vehicle-based driver-assistance systems influence freeway traffic. We present results for a section of the German Autobahn A8-East. Both, a speed limit and an on-ramp control could considerably reduce the severeness of the originally observed and simulated congestion. Introducing 20% vehicl...

Both epidemics and sporadic cases of cerebrospinal meningitis (CSM) are known to occur. Among the different bacteria causing the disease, the most frequent etiological agents are Neisseria meningitis, Streptococcus pneumoniae and Haemophilus influenzae. The bacterial forms of meningitis constitute a serious public health problem in that they cause high mortality, particularly in children and in...

Availability of measures that would predict controller success in his or her task and the impact of changing procedures and advancing technology on the system as a whole is imperative to the success of modernization of air traffic control (ATC) systems worldwide. This paper describes a database that is populated by the results of previous reviews of ATC research literature, organized according ...

This paper relates to an approach described in [5] which, for the pricing of bonds and bond derivatives, is alternative to the classical approach that involves martingale measures and is based on the solution of a stochastic control problem, thereby avoiding a change of measure. It turns out that this approach can be extended to various situations where traditionally a change of measure is invo...

In this thesis, we study the problem of maximizing certain concave functionals on the space of optional random measures. Such functionals arise in microeconomic theory where their maximization corresponds to finding the optimal consumption plan of some economic agent. As an alternative to the well–known methods of Dynamic Programming, we develop a new approach which allows us to clarify the str...
