We provide a deterministic algorithm that constructs small point sets exhibiting a low star discrepancy. The algorithm is based on bracketing and on recent results on randomized roundings respecting hard constraints. It is structurally much simpler than the previous algorithm presented for this problem in [B. Doerr, M. Gnewuch, A. Srivastav. Bounds and constructions for the star discrepancy via...

Since a ship yard usually provides insufficient data for developing a ship control system, the course and track controller design is based upon a Nomoto model determined with a Clarke estimation of hydrodynamic derivatives. Several ships examined show a poor system performance with a course control derived from these models besides parameter identification problems of adaptive control concepts....

INDIAN PEDIATRICS 724 VOLUME 42__JULY 17, 2005 Only 37% and 60% participants could correctly identify frozen and unfrozen vaccine vials respectively. This raises serious doubts about the validity and utility of the Shake test (as given in the module). In addition, the Shake test protocol is not correctly given in the module. Non-frozen sample cannot be used as a control vial. Besides this, the ...

The use of model-based controller or fault diagnosis systems in automotive control requires reliable dynamics models. The reliability consists in accurate prediction of the vehicle’s behavior, in order to evaluate current driving situations. Model parameters have to be precisely identified. This depends on the model’s capability to reproduce the complex dynamics of the real system, by remaining...

This paper shows the application of robust control techniques to a solar plant integrated in an air conditioning system. Different structures in an specific loop are applied, because of the complexity of the whole system. Besides the classical feedback loop, the plant controller includes also a feed forward one to reject measurable disturbances as radiation. The design methodology and some simu...

This review addresses the catalytic reactions performed in microstructured reactors, which are more and more recognized in recent years as a novel approach for chemistry and chemical process industry. They are particularly suited for highly exothermic and fast reactions allowing temperature control and isothermal operation. A brief evaluation of the advantages for gas-phase, liquid-phase, and g...

In this article, we survey the sensor network calculus (SensorNC), a framework continuously developed since 2005 to support the predictable design, control and management of large-scale wireless sensor networks with timing constraints. It is rooted in the deterministic network calculus, which it instantiates for WSNs, as well as it generalizes it in some crucial aspects, as for instance in-netw...

The use of accumulation vessels – production separators, electrostatic treaters, etc – as filters of feed oscillations has been proposed to optimize the offshore treatment of crude oils. This change in philosophy of control suggests letting the level to oscillate within certain limits – called band – for which existing algorithms require the measurement of the flow rate. An alternative algorith...

Collision and turnover are fatal to mobile robots. Control methods are suggested for solving the fatal problems of mobile robots maneuvered by an operator. Speed reduction and wall following are applied for collision avoidance using ultrasonic sensor data. Modified Hough transform is suggested to obtain a wall model from sonar data overcoming limitations of ultrasonic sensors. The robot is also...
