A new chemical reactor, the Open Plate Reactor, is being developed by Alfa Laval AB. It combines good mixing with high heat transfer capacity. With the new concept, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a process control system is developed.A utility system to provide the reactor with cooling water is designed
In this paper the advantages of accelerator-based chemical analysis of work environment aerosols are discussed. Use of the PIXE method is central, but in order to take full advantage of the possibilities of an accelerator laboratory, it should be combined with nuclear methods such as particle-induced nuclear reactions and/or particle scattering for simultaneous measurements of light elements. It i
This text shows how the use of archaeological evicence in reconstructing the past give different views of each period in the past, from the Stone Age to the Middle Ages. Reconstructing the past is an adventure based on both knowledge and experience.
This paper addresses the design of self-timed energy minimum circuits, operating in the sub-VT domain. The paper presents a generic implementation template using bundled-data circuitry and current sensing completion detection. To support this, a fully-decoupled latch controller has been developed, which integrates the current sensing circuitry. The paper outlines a corresponding design flow, which
A developing system must be able to learn new things without forgetting what it has learned before. It should be capable of reacting in different ways to the same stimuli in different contexts. Context sensitive reinforcement learning, which parallels some of the functions of the basal ganglia, is a learning algorithm that fulfills this requirement when the context is explicitly given. Here, we ex
Popular Abstract in Swedish Den första delen av denna avhandling behandlar teoretiska aspekter på stärkelsens kristallina egenskaper. Vår förståelse av dessa egenskaper är baserad på modeller som erhållits via kristallografiska undersökningar av modifierad amylos. Mycket tyder på att dessa modeller är direkt överförbara till amylopektin som utgör den kristallina komponenten i stärkelse. En stor deThe crystalline properties of starch constitutes a puzzling area of research. Our understanding of the crystalline structure of amylopectin, that is the crystalline component in starch, is based on the observations from investigations on modified amylose. The first part of this thesis includes a discussion of the unit cells (the smallest crystalline units) suggested in the literature. The differen
