Abstract:

Abstract Environmental concern and tighter public regulations have created new pressures to reduce effluent loading from kraft pulp bleaching during the past decades. This trend has forced both pulp mills and the related engineering industries to develop and optimise equipment for the pulping processes which fulfils these demands. New pulp washers and washing systems connected with the introduction of new oxygen-based reagents have in particular provided considerably improved tools for reusing process water and thereby essentially reducing effluent discharge or even allowing the implementation

Full text

Abstract:

All land uses affect storm water runoff However, different uses of the same site generate varying amounts of runoff Many communities have come to rely upon detention and/or retention basins for controlling the additional runoff resulting from land development. It is argued that this incremental approach to storm water management must be replaced with a more proactive long-term view.To achieve this, more user-friendly software capable of modeling the effect long-range land use plans have on the volume and behavior of storm water runoff is needed. This software, called a Spatial Decision Support

Abstract:

In the recent years, Global Navigation Satellite Systems (GNSS), in particular Global Positioning Systems (GPS), have proved their capacity to monitor atmospheric water vapor with an accuracy that is comparable to the accuracy of other conventional meteorological sensors. GNSS has several significant advantages compared to the traditional observational systems, including low operating expense, all-weather operability and high temporal/spatial coverage. As a result, the provision of Zenith Total Delay (ZTD) and derived Precipitable Water Vapor (PWV) from GNSS data has become established as a st

Abstract:

M.Ing.<br>The aim of this research was to investigate the use of stream processing on the graphics processing unit (GPU) and to apply it into the hydraulic modelling of a water distribution system. The stream processing model was programmed and compared to the programming on the conventional, sequential programming platform, namely the CPU. The use of the GPU as a parallel processor has been widely adopted in many different non-graphic applications and the benefits of implementing parallel processing in these fields have been significant. They have the capacity to perform from billions to tril

Imagem de MRS (MRSI) no cérebro permite detetar espectros de múltiplos voxels e, consequentemente, a heterogeneidade espacial de concentrações metabólicas, o que pode ser um indicador de doenças neurológicas e metabólicas. Contudo, MRSI é tecnicamente mais desafiante em campo

Abstract:

M. Tech.<br>The mechanism of microwave assisted waste oil and water emulsions destabilisation is analysed. The broad overall features of the microwave system to break emulsions are established and the design specifications of each constituent component are set. The type of well suited microwave cavity is selected. After analysis, the multimode cavity proves to be a suitable choice. The established overall dimensions of the cavity are set and used to visualize the field pattern in the treatment chamber. Some MATLAB routines are written and used to enhance the visualization of the field pattern

Abstract:

The budgeting of water fluxes in the soil is an extremely complex problem, and is compounded by subsurface controls and environmental forces which modify the soil water dynamics. Of the controlling factors, the underlying geology and the soil media are vital components and are often misinterpreted. The geology and soil media components have been neglected mostly because of the difficulty in monitoring the dominant processes that are linked to the water balance in the subsurface. Until recently, hydrometry has been the dominant method of measuring and monitoring the subsurface water balance. Hy
