Differential optical absorption spectroscopy (DOAS) and differential absorption lidar (DIAL) have been used for measurement of atmospheric trace gases. A fully automated system for atmospheric pollution monitoring of a medium-sized city has been constructed, based on the DOAS technique. Detection of ammonia and aromatic hydrocarbons in the ultraviolet spectral region has been investigated and demo
Neural networks learn knowledge from data. For a monolithic structure, this knowledge can be easily used but not isolated. The many degrees of freedom while learning make knowledge extraction a computationally intensive process as the representation is not unique. Where existing knowledge is inserted to initialize the network for training, the effect becomes subsequently randomized within the solu
The aim of this paper is to present trends, similarities and differences in the usage of graphical languages at the level of Process Control, manufacturing Operations and Business Systems. The paper also gives ideas of how a common language could be used to increase the integration between the three levels and what advantages this could bring to its user.
A controller synthesizer, that is part of a design system by which algorithms unsuitable for standard processors can be implemented, is presented. A hierarchical controller architecture suitable for frame-based and multi-sample-rate algorithms is synthesized. Synthesis of a controller is based on micro instructions, specific for each architecture, and assumes no use of predefined functional blocks
Scanias motormonteringsverkstad i Södertälje använder sig av en motorpall för att internt hantera motorer. Motorpallen används även externt som transportemballage för motorleveranser tex. till Scanias slutmonteringsenheter. Motorpallen är anpassad till samtliga Scanias motorer och är tillverkad av stål. Scania uppskattar att totalt 2 500 motorpallar cirkulerar i det slutna flödet och att kostnaden
Every year about 15 million people are injured in traffic, 500,000 of these fatally. Developing countries are badly affected. During the worst years of the war in Nicaragua, more people died in traffic accidents than as a direct result of the war. Transport system and infrastructure have developed rapidly in developing countries, while little has been achieved in preventing accidents or lessening
In this note the objectives of a project financed from European Community in the FP7 to realize a cleaning system for a syngas obtained from the gasification of biomass will be reported. In order to us the obtained sysngas can be transformed with further catalytic processes previously eliminating sulphur chlorine, COS, HCN NH3 and tars.
Choosing the right mortar for the job, and applying it correctly, gives a strong structure requiring less maintenance. A common problem is using too much cement in the mix, which is unnecessarily expensive and has technical disadvantages. Another common problem is using too thick a layer of rendering, which increases the risk of flaking and cracking. A masonry wall must meet several requirements
