A new reactor type has been designed by Alfa Laval AB,the open plate reactor (OPR). It combines good mixing with high heat transfer capacity. With the new open plate reactor, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a model from first principles is derived. The paper concerns the control properties of the platere
Stationary solar energy concentrators are a promising option for decreasing the price of photovoltaic electricity. This thesis studies stationary concentrators in PV/Thermal applications. The studied systems are parabolic troughs intended for building integration. The first chapters briefly explain the optics of solar energy concentrators. The theoretical maximum concentration ratios of two and th
Guaranteeing stability of control applications in embedded systems, or cyber-physical systems, is perhaps the alpha and omega of implementing such applications. However, as opposed to the classical real-time systems where often the acceptance criterion is meeting the deadline, control applications do not primarily enforce hard deadlines. In the case of control applications, stability is considered
Substituted thiophene-1,1-dioxides were synthesized and their ring-opening reactions with omega-unsaturated secondary amines were investigated; this led to a synthetic route to azatrienes and to the preparation of some polyhydroisoindoles and polyhydroisoquinolines via an intramolecular Diels-Alder reaction. By using 2-substituted pyrrolidines and piperidines various tetrahydrobenzo[f]indolizidine
Program parallelization becomes increasingly important when new parallel and multi-core architectures provide ways to improve performance. In this paper, we address parallel search in constraint programming (CP) by proposing several load-balancing methods. We show how these methods improve the execution-time scalability of constraint programs. Scalability is the greatest challenge of parallelism a
