Det här självständiga arbetet inom militärteknik behandlar hur dagens tekniska tillämpningar avseende pansarvärnsrobotsystem kan möta en kvalificerad motståndare. Hotbilden med varnar- och motverkans-system medför att de tekniska och de stridstekniska kraven har förändrats för att både nå verkan samt överleva i stridsställning. Utifrån kända data och prestanda på både robotsystem samt varnar- och mot-verkanssystem har beräkningar gjorts för att studera tidsförhållanden i en duellsituation. Skillnaderna har tillsammans med tekniska specifikationer analyserats och diskuterats för att ge svar på studiens fråge-ställning: Vilka tekniska möjligheter och begränsningar har dagens pansarvärnsrobotsystem för att möta en kvalificerad motståndare med varnar- och motmedelsystem i svensk småbruten terräng? Resultatet visar på följande möjligheter och begränsningar:Den kvalificerade motståndaren har sensorer och motmedel med god förmåga att upptäcka och bekämpa pansarvärnsrobotsystem. Korta skjutavstånd (˂2 000 m), höga robotbanor, salvskjutning med robusta robotsystem vilka styrs autonomt, maskering och störning av motståndarens sensorer ger pansarvärnsro-botförbandet tekniska möjligheter att med framgång möta även en kvalificerad motståndare.

A support vector machine (SVM) classifier was designed to replace a previous classifier which predicted oyster vessel behavior in the public oyster grounds of Louisiana. The SVM classifier predicts vessel behavior (docked, poling, fishing, or traveling) based on each vessel’s speed and either net speed or movement angle. The data from these vessels was recorded by a Vessel Monitoring System (VMS), and stored in a PostgreSQL database. The SVM classifier was written in Python, using the scikit-learn library, and was trained by using predictions from the previous classifier. Several validation and parameter optimization techniques were used to improve the SVM classifier’s accuracy. The previous classifier could classify about 93% of points from July 2013 to August 2014, but the SVM classifier can classify about 99.7% of those points. This new classifier can easily be expanded with additional features to further improve its predictive capabilities.

The world-class Buchans Mining Camp hosts a number of high-grade, low-tonnage volcanogenic massive sulfide (VMS) deposits. The Lundberg and Engine House zones form the lower-grade stockwork to the Lucky Strike deposit and have yet to be mined. A detailed study of the Lundberg and Engine House zones was conducted to establish the stratigraphic setting of the deposits, to determine the petrology of the host volcanic rocks and distribution of alteration facies, and to characterize the mineralization with the goal of improving exploration for polymetallic massive sulfide deposits in the Buchans camp.

The 2.68 Ga Zn-Pb-Cu-Ag Hackett River Main Zone (HRMZ) volcanogenic massive sulfide (VMS) deposit, within the Hackett River Greenstone Belt of the Archean Slave Craton is highly enriched in Ag (and Pb) compared to other VMS deposits of a similar age and type. The mineralization has been sub-divided into five categories based on mineralogy, textures and stratigraphic location: 1) disseminated footwall sulfides, 2) copper-rich stringer sulfides, 3) pyrite-poor sphalerite-pyrrhotite-chalcopyrite mineralization located at the top of the stringer zone, 4) mineralization in calc-silicate altered units and 5) sphalerite-pyrite massive sulfide mineralization. Using a mass-balance for Ag calculated from electron microprobe analyses, pyrrhotite and chalcopyrite in type 1 mineralization contain negligible Ag and in type 2, Bi-Ag-(Pb) sulfides, Ag-Bi-Se enriched galena and chalcopyrite are the dominant Ag hosts. Within type 3, freibergite and galena are the main silver hosts. In type 4, Ag is hosted in disseminated electrum and freibergite while freibergite in type 5 hosts 99% of the Ag. Overall, Ag-rich freibergite contains 79.4% of the total Ag, chalcopyrite hosts 6.3% and galena contains 1.8% of the Ag. Trace minerals such as electrum, stephanite, acanthite and Bi-bearing sulfides host the remainder of the Ag (12.5%) and have a restricted spatial distribution. Mineral assemblages have undergone pervasive recrystallization and annealing during amphibolite grade metamorphism with localized redistribution of base and precious metals from metamorphism at a grain scale only. Within freibergite and chalcopyrite, Ag directly substitutes for Cu within the mineral lattice and replaces Pb in galena by coupled substitution with Bi and to a lesser extent, Sb. The principal controls on Ag residence in the HRMZ are temperature and redox conditions (which varies with distance to the hydrothermal vent) and the ratio of Bi and Sb available for coupled substitution with silver within galena. Subsequent deposit-scale zone refining is the principal factor influencing the distribution of Ag. Lower temperatures and more oxidizing conditions favour partitioning of Ag into freibergite and less oxidizing conditions favour galena. At higher temperatures, the most reducing conditions favour incorporation of Ag in Ag-Bi rich galena (plus Se) and Bi-bearing sulfides or Ag-rich chalcopyrite under lesser reducing conditions. / Thesis (Master, Geological Sciences & Geological Engineering) -- Queen's University, 2009-03-12 10:46:49.993

Brytning av ekonomiskt värdefulla resurser sker över hela världen och effektiviseras kontinuerligt. Ökad brytning av mineral innebär att lättåtkomliga malmkroppar förbrukas. När de lättåtkomliga kropparna av dessa mineraler använts upp krävs det prospekteringsmetoder för att leta djupare in i jordskorpan. En sådan metod är borrkärnekartering.Syftet var att detaljerat beskriva borrkärnans petrofysiska egenskaper samt lokalisera potentiell ekonomiskt område med hjälp av borrkärnekartering. Två borrkärnor karterades och undersöktes med hjälp av en handhållen XRF. Borrkärnekarterings potential som prospekteringsmetod utvärderades.Malmkropp innehållandes stor del Zn samt Pb, Cu och Fe identifierades i båda borrkärnorna. pXRF och kartering lokaliserade malmkropp i liknande omfång och gradering. Ursprungsbergarter och dess sammansättning identifierades.Prospekteringsmetoder som borrkärnekartering fungerar mycket bra i de fall övergripande information om borrkärnan behövs omgående. Borrkärnekartering är således en effektiv metod som kan användes vid borrplatsen för att kontinuerligt ge information om borrkärnan och således avgöra om borrning ska fortsätta eller avslutas. Prospekteringsmetoden fungerar bäst i kombination med andra metoder, geokemiska eller geofysiska. / Mining of economically important resources is a process happening all over the world and have been increasing in effectiveness during the last century. Increased mining of the resources means that the easily accessed bodies of these minerals is exhausted. Prospecting methods to find new bodies in the ground is then needed. One of these methods is core logging.The goal of the project was to locate potential valuable mineralization. Two different cores were logged and evaluated with a hand held XRF during the project. The effectiveness of core logging as an exploration method was evaluated.Ore body containing large amounts of Zn as well as Pb, Cu and Fe were identified in both drill cores. pXRF and logging gave the same size and grades of the ore body. Protoliths and its composition were identified.Exploration methods like core logging is useful when summary information of the drill core is necessary and the information needs to be given fast. The method is therefore effective in the field at the drill stations to give continuously information about the drill cores being drilled. The method is most effective when combined with other methods like geochemical or geophysical methods.
