Gravar i stenskepp : Osteologisk analys av brända och obrända ben från skeppssättningar på Gotland / Burials in Stone ships : An osteological analysis of burnt and unburnt bones from stone ship settings on the island of Gotland

Gustavsson, Anders January 2011 (has links)
In this study bone material from six stone ship settings and a total of seven deposits of bones from two sites on the island of Gotland have been analyzed. Four ship settings from the burial site at Gålrum in Alskog parish and two from Tängelgårda in Lärbro parish. The ships contained both cremated remains and inhumations.  Human remains were identified in five of the analyzed ship settings and a minimum of six individuals was identified in total.  Animals were found in three of the ship settings, where one of them contained only the burned remains of a dog. Two of the ships contained inhumations, one in Gålrum and one in Tängelgårda. The one from Gålrum was determined to 17-19 years of age but of undetermined sex. The inhumation from Tängelgårda was determined to a male of 35-64 years of age.  Of the cremated remains none could be determined to sex but all were determined as adult individuals. The temperature that the cremated bones had been exposed to during the cremation was similar between the different ship settings, with one exception which had been exposed to a slightly higher temperature. The results of the material have also been compared with those of other osteological analysis from ship settings on Gotland. The interpretation of this has been that the amount of bone and the number of individuals that has been buried in stone ship settings vary from different sites. Some ship settings have contained several burials and have been interpreted as family graves (Pettersson 1982) which do not fit with the results from this analysis where all the ship settings contained a maximum of one or two human individuals, so the results from the ship settings on Gålrum and Tängelgårda differ from earlier interpretations of ship settings on Gotland.

Energy Storage Solutions for Wind Generator Connected Distribution Systems in Rural Ontario

Rahman, Mohammed Nahid January 2009 (has links)
Environmental awareness and uncertainty about continued supply of fossil fuel has given rise to the renewable energy movement. Wind based power generation has been at the forefront of the motion to integrate distributed energy sources in the traditional power system. Due to various technical restrictions, wide scale penetration of wind generated power has been held back by most utilities. One such restriction is the variability of generation due to the technology’s dependence on Mother Nature. Energy storage devices can complement the wind generators by reducing this variability. These devices can store excess generation for supply during low generation periods. There are several promising technologies for both energy storage and power storage applications. Power storage devices provide short term fluctuation dampening capability while energy storage devices allow longer term storage. Pumped hydro, Vanadium Redox battery and Sodium-Sulphur battery are some of the viable energy storage technologies. This project provides a set of algorithms and guidelines to obtain the optimal configuration parameters of an energy storage device. To verify the efficiency of the algorithms, a model system has been obtained from a local utility. This system represents a typical radial distribution system in rural Ontario. The load demand, wind speed and energy prices for a period of one year have been obtained from utilities and Environment Canada. The main goal in determining the location of the storage device within a distribution system is to minimize the total cost of energy and the total energy loss during the period of analysis. Locating the storage device near the wind turbines or near the largest loads lead to the optimum results. Buses that are located near those elements can be considered as suitable locations for the storage device. The energy storage capacity and charge-discharge rate of the storage device are selected based on four criteria: maximize wind turbines’ load following capability, maximize capacity factors of the wind turbines, minimize system energy losses and minimize system energy costs. A weight based multi-objective optimization algorithm has been proposed to assign various priorities to these criteria and obtain a single solution. The larger the energy storage capacity of the storage device, the better the improvement in system performance. Lower charge-discharge ramp rates provide superior results. The parameters for storage device operating schedule, i.e. charge-discharge trigger levels, have been selected using similar criteria and weighted objective approach as for the capacity selection process. Higher charge trigger levels and moderate discharge trigger levels provide the optimum system performance. Once a set of parameters for the storage device has been selected, bus voltages over the period of study are analyzed. Voltage variations outside certain limits have been identified. Finally, a Monte Carlo based simulation approach is presented to obtain output parameter (system performance) variation ranges for pseudo random changes in input parameters.

Artefacts and bone patterns in stone ship settings on Gotland / Fynd och benmönster i skeppssättningar på Gotland

Gustavsson, Anders January 2012 (has links)
This thesis is an attempt to gather and discuss the archaeological and osteological results that has been found in stone ship settings on Gotland. The bone material from five ship settings, one stone setting and a cairn from the bronze age complex at Rannarve in Klinte parish on Gotland has been osteologically analysed during this study to further expand the osteological results that are available from ship settings on Gotland and try to interpret this site. The aim is to try to find what artefacts and bone patterns that can be distinguished from the material found within ship settings. What patterns can be seen in artefacts, age, sex and burial contexts that has been found in ship settings? What are the most common patterns? / Den här uppsatsen är ett försök till att samla och diskutera vilka arkeologiska och osteologiska resultat som påträffats i skeppssättningar på Gotland. Benmaterialet från fem skeppssättningar, en stensättning och ett röse i Rannarve i Klinte socken på Gotland har analyserats osteologiskt för att utöka de osteologiska resultaten som finns tillgängliga för skeppssättningar på Gotland samt för att försöka tolka platsen. Målet är att försöka se vilka föremål och benmönster som går att urskilja från materialet och se vilka mönster som finns mellan fynd, ålder, kön och gravkontext i de olika skeppssättningarna, samt vilka mönster som är de mest vanliga.

Auditory distractions in open office settings: a multi attribute utility approach to workspace decision making

Juneja, Parminder K. 22 April 2010 (has links)
In open office settings, auditory distractions coming from surrounding work environment are shown to be a considerable source of indirect costs to an organization, such as performance costs, behavioral costs, and healthcare costs, to name a few. These costs are substantial to affect the net productivity of an organization, where productivity is equal to revenue minus the costs. This research argues that the costs of auditory distractions should be estimated when evaluating the value of a workspace for an organization. However, since organizational decisions are generally guided by cost-benefit analysis and a precise dollar figure cannot be attached to the stated indirect costs because these are subjective in nature; therefore, these are generally ignored. Costs that are critical to sustainability and development of a business and the fact that cost-benefit approach is no longer appropriate for these decisions, a more robust decision-based approach to workspace selection is proposed. Decision-based approach is seen as an organized approach to select between workspace options under uncertainty and risk wherein the selected workspace is maximized in terms of some expected utility. Here utility is defined as the measurement of strength or intensity of a person's preferences. Decision-based approach include consideration of a multitude of environmental decision variables, objective or subjective, in a single equation and processing of the same in a limited amount of time with rationality and consistency. A multi-attribute workspace choice utility decision model is developed with the intent to facilitate systematic understanding and analysis of workspace alternatives for an organization. This research shows how the decision-making approach to workspace selection simplifies the problem by providing a structure that is easily comprehensible, and allows simultaneous processing of both, qualitative and quantitative conflicting objectives, through a single decision-making model. In doing so, this research firmly establishes the importance of workspace's adaptability to auditory distractions for office workers, particularly knowledge workers, who are constantly undertaking a range of complex tasks. The study holistically and systematically addresses the fundamental issue prevalent in state-of-the-art North American open plan office settings of substantiality of two extremely contrasting requirements, concentration and collaboration, in the same workspace and work environment at a given time.

The School as a Setting to Promote Student Health

Saab, HANA 06 October 2009 (has links)
The Health Promoting School (HPS) is s a model that advances both the health and learning needs of students. Yet there is a lack of consensus on student indicators that reflect a HPS or a coherent understanding of what a HPS represents amongst various stakeholders. The goal of this research was to establish indicators of student health and wellbeing associated with policies and practices in schools, and to further our understanding of health promoting schools. The research proceeded in three phases. The first phase established a relationship between student health and academic achievement. The second phase examined the associations amongst student health and wellbeing and student and school-level factors. The third phase involved case studies of two schools in Ontario to examine the organisational and structural elements associated with achieving a HPS, and the mechanisms by which these elements support student health and wellbeing. The association between students’ self-rated health and their academic achievement found in the first phase provides a platform for advancing the health promoting school agenda in Canada at the research and policy levels. Subsequent findings established an association between the environment and disciplinary climate in schools, and the school’s academic and socioeconomic standing to student health and wellbeing outcomes. These findings also suggest overlapping effects of schools and neighbourhoods on students’ health and wellbeing, implying that school health promoting efforts will be more successful when partnered with efforts within neighbourhoods and communities. Finally, the case studies suggest that embracing a HPS philosophy that addresses students’ emotional and physical wellbeing may help support students’ overall learning. Findings, presented in an implementation model of a HPS, emphasise key action areas that need to be addressed when implementing HPS initiatives and enhancing the capability of the education system to improve the health and learning of students. / Thesis (Ph.D, Education) -- Queen's University, 2009-10-05 13:45:06.342

Inside is the sky : for mezzo soprano and chamber orchestra

Hall, Emily January 2005 (has links)
Inside is the Sky is a musical composition for mezzo soprano and chamber orchestra. It is a collection of four songs using poems by renowned Canadian poet Lorna Crozier: A Summer's Singing, In Moonlight, Tautologies of Summer, and Inner Space. The composer wishes to connect music and poetry on a fundamental level. The approach is to write music that responds not to the mere surface of the poems, but rather to their central poetic themes, by means of parameters intrinsic to music: harmony, rhythm, melody, and registral expanse.

Denna rapport handlar om utveckling av administratörsfunktioner för applikationen QuickPick som är ett värdesystem för ett lager. I dagsläget finns det inga funktioner för användaren att sortera, gruppera eller filtrera vyinställningar i applikationen. De som använder systemet får kontakta Qsys Sverige AB, där detta uppdrag är utfört, för att ändra vyinställningar manuellt. Rapporten behandlar teori om hur ett lager är uppbyggt, hur man programmerar på ett generellt sätt så att det blir enklare att fortsätta utveckla funktionen. Teorin behandlar också hur man på ett användarvänligt sätt skapar ett system för en administratör.Funktionerna kommer att finnas i en webbportal tillgänglig för administratören och är utvecklat i C# och ASP.NET. Resultatet av rapporten är fungerande administratörsfunktioner för vyinställningar i en webbportal som kan användas i QuickPick applikationen. / This thesis is about development of administrative functions for the application QuickPick, which is a value system for warehouses. Today, there are no functions for the user to sort, group or filter the view settings in the application. Those who use the system need to contact Qsys Sverige AB to make this changes. Where also this thesis has been performed. The thesis deals theoretically with how a warehouse works, how you program in a general way, so it will be easier to continue the development of the functions and make a user friendly system for an administrator. The new functions will be available in a web-portal for administrators and it has been developed in C# and ASP.NET. The result of the thesis will be administrative functions for the view settings in a web-portal which can be used in the QuickPick application.

Text/music relationships in five posthumous songs by Alexander Zemlinsky / Text music relationships in five posthumous songs by Alexander Zemlinsky

Rodenberg, David January 2004 (has links)
This study centers on a 1907 collection of art songs for voice and piano composed by Alexander Zemlinsky. Although his small cycle of five songs was not published during the composer's lifetime and has not been given the scholarly attention that other pieces in his oeuvre have, it is well crafted and carries a high degree of expressive and emotional weight. The cycle sets the poetry of Richard Dehmel; a contemporary of Zemlinsky and the inspiration behind works of Arnold Schoenberg, Anton Webern and Richard Strauss as well. In these 1905 settings Zemlinsky experiments with an extremely chromatic language while exploring themes of love and betrayal in the poetry of Dehmel. This study examines this chromatic style and how it relates to the themes in the text. Through the detailed analysis of each of the songs the reader will see how, in spite of the free succession of harmonies that often obscure the tonal orientation, a central underlying tonic/dominant relationship is at the core of each song except the first. In this manner the songs display a subtle yet powerful exploitation of tonal ambiguity that brings out many of the nuances of Dehmel's poems. / School of Music
