Abstract:

Emitter location finding enables important functionality for both military and civilian applications. GPS is the most recognized and widely used positioning system, but it is a receiver location system that functions in a markedly different manner from emitter location. Many geo-location techniques predate and have been proposed as an alternative to GPS. Some of the more commonly used and exploited of these techniques are angle of arrival, time of arrival, frequency difference of arrival, and time difference of arrival (TDOA). This thesis is primarily focused on TDOA. These techniques are impo

Non-invasive geophysical datasets can provide more dense 2D/3D information.

Abstract:

This paper summarises the results of using image processing technique to get information about the load of timber trucks before their arrival using digital images or geo tagged images. Once the images are captured and sent to sawmill by drivers from forest, we can predict their arrival time using geo tagged coordinates, count the number of (timber) logs piled up in a truck, identify their type and calculate their diameter. With this information we can schedule and prioritise the inflow and unloading of trucks in the light of production schedules and raw material stocks available at the sawmill

This thesis aims to investigate and assess the future conditions for Volvo GTO Umeå after the installation of a new pre-treatment facility. The treatment method used is physical-chemical precipitation. Its function is to precipitate contaminants such as nickel, zinc and phosphorus, make them flocculate by adding a coagulant and separate the flocs by sedimentation. An investigation was carried out at the Volvo plant to locate the major inflow of waste water. These major inflows was analyzed and future scenarios was predicted by estimating a lower pre-treatment flow volume. The future scenarios

The knowledge of the microstructural properties of cement-based materials plays a fundamental role in predicting their macroscopic behaviour in terms of performance and durability.

Abstract:

The characteristic wind field of a certain region is mostly governed by the climatology of its larger scale area. In the case of mid-latitude regions (e.g. Europe), their climatology is determined by the extra-tropical cyclones at the larger synoptic scale. Atmospheric boundary layer (ABL) winds based on synoptic-scale structures are hence considered as the foundation for codes and standards used to assess the wind loading of structures and to design structures to prevent wind-related damage accordingly. In addition to the ABL winds, the mid-latitude regions are also prone to winds of a non-sy

Abstract:

The removal of scattered radiation is recognised as one of the major goals to be achieved in SPECT. In this work three scatter removal techniques were investigated. These were dual window scatter subtraction, deconvolution using a Wiener filter and energy weighted acquisition (EWA) using a weighted acquisition module (WAM). In addition to this, the effects of simple background subtraction on SPECT images was also investigated. The techniques were investigated in both a semi-quantitative manner, in terms of the effects of each technique on the cold lesion contrast and image mottle, and qualitat

Abstract:

The initial aim was to establish conventional DNA typing technology for blood group typing using cell derived genomic DNA material from donors. Accordingly, blood samples were collected from 200 healthy, randomly selected, Aberdeen Regional blood donors. The DNA extracted from these samples was used to develop and validate PCR assays for RHD, RHDPsi, RHC/c, KEL1 and KEL2, Fya and Fyb and ABO blood group alleles. All samples were also phenotyped serologically for RH, KEL, Duffy and ABO blood groups. Complete concordance was observed between phenotype and genotype. The developed RHD, RHDPsi and

Abstract:

Effective techniques for assessing soil environmental pollution are required to develop protective policy. Chemical methods have been traditionally used to determine total concentration of pollutants and biologically linked measurements have been used to assess the bioavailable fraction of pollutants. Bioluminescence-based microbial bioassays have been shown to respond to the bioavailable fractions. Growth and bioluminescence of lux-marked E. coli HB101 and P. fluorescens 10586r were characterised and optimised for freeze-drying culture. Freeze-drying cultures have been used effectively becaus

Abstract:

Les aspects anatomiques d'une technique d'anesthesie loco-regionale du nerf mandibulaire, decrite en 1973 par gow-gates, sont etudies. La specificite anatomique et l'utilisation clinique de cette technique, repandue dans les pays anglo-saxon motivent ce travail. Il constitue une simulation experimentale qui permet une evaluation des risques anatomiques particuliers de la technique. La caracteristique de la technique de gow-gates est de viser la face antero-mediale du condyle mandibulaire a distance du nerf mandibulaire a anesthesier. L'auteur determine comment la solution anesthesique parvient
