WetNet operations

WetNet is an interdisciplinary Earth science data analysis and research project with an emphasis on the study of the global hydrological cycle. The project goals are to facilitate scientific discussion, collaboration, and interaction among a selected group of investigators by providing data access and data analysis software on a personal computer. The WetNet system fulfills some of the functionality of a prototype Product Generation System (PGS), Data Archive and Distribution System (DADS), and Information Management System for the Distributed Active Archive Center. The PGS functionality is satisfied in WetNet by processing the Special Sensor Microwave/Imager (SSM/I) data into a standard format (McIDAS) data sets and generating geophysical parameter Level II browse data sets. The DADS functionality is fulfilled when the data sets are archived on magneto optical cartridges and distributed to the WetNet investigators. The WetNet data sets on the magneto optical cartridges contain the complete WetNet processing, catalogue, and menu software in addition to SSM/I orbit data for the respective two week time period

National Music Education Standards and Adherence to Bloom\u27s Revised Taxonomy

Pressures from education reforms have contributed to the need for music educators to embrace new and diverse instructional strategies to enhance the learning environment. Music teachers need to understand the pedagogy of teaching and learning and how these affect their praxis. The purpose of this multiple case evaluative study was to investigate the instructional methods used in 10 middle school general music programs to assist students in obtaining the National Standards for Music Education. Bloom\u27s revised taxonomy was the theoretical framework used to evaluate the teaching praxis of the participating teachers. The research questions for the study addressed the effectiveness of the instructional strategies in the music classroom and how they align with the National Standards Music Education and Bloom\u27s Revised Taxonomy. Data were collected from an open ended survey, individual interviews, and unobtrusive documents from 10 general music teachers from suburban, rural, and urban school districts. A line-by-line analysis was followed by a coding matrix to categorize collected data into themes and patterns. The results indicated that standards-based metacognitive instructional strategies can assist music teachers in their classrooms and unite cognitive, affective, and kinesthetic experiences applicable beyond the music classroom. It is recommended that music teachers use alternative teaching techniques to promote and connect critical thinking skills through musical learning experiences. Implications for positive social change include training music educators to create learning environments that support and motivate students to learn and achieve academic success

Modelling Combined Heat and Power Plants: Modelling CHP Plants on a System Level in the EMPS Power Market Model

Combined heat and power ( CHP ) plants enable simultaneous production of electricity and useful heat allowing for high total fuel efficiency. 70 % of all electricity produced in Denmark in 2012 was produced from plants classified as CHP plants. Because of the close power market connection between Norway and Denmark, a sufficient modelling of the Danish production portfolio is important to Statnett, the Norwegian TSO.CHP plants are very complex to model at a system level as they participate in both power and heat markets and exist with such technological diversity. The objective of this thesis was to uncover potential for improvements and to implement new modelling elements to the modelling of Danish CHP plants in the SINTEF developed EMPS power market model. The EMPS model does not explicitly model heat markets.Three areas were found to have potential for improvements:1. The average annual production profiles: the existing production profiles were too volatile, seemingly random and lacked documentation2. The aggregation of small CHP plants: The existing aggregation of small CHP not sufficiently diversified to account for technological diversity at a system level3. Temperature dependent capacity: the CHP production was not temperature dependent apart from a general seasonal variability.It was assumed that CHP units operation can be modelled by a linear feasible operating region describing the relation between instant heat and power production. CHP utilities must meet the heat load at all times. Based on assumptions about the heat load as a function of outdoor temperature and historical temperature data, new annual production profiles relating to average temperature were created. A new method of aggregating small CHP plants was developed based on decentral DH utility statistics and a new way of determining their marginal cost. In addition, a function developed by SINTEF that corrects the CHP production capacity according to the actual temperature was implemented. The new modelling elements were largely based on a CHP operation strategy developed for this thesis.The new elements were implemented in steps to see the effect of each step. The implementations formed three new EMPS model datasets, in addition to the one for the pre-existing modelling. Each element was shown to have been implemented correctly and addressed the issues as intended.When comparing thermal production per week [GWh] from observed data with modelling results for the period 2001-2008 it was shown to be a trend that modelled thermal production follows the observed thermal production in general for all datasets. This is largely due to general, seasonal variations in available back pressure capacity at a low MC.However, the degree to which the data fitted with this trend varied amongst the model datasets. The new modelling elements proved to be incremental improvements with regards to following the observed thermal production from week to week. The pre-existing modelling performed worst and the new dataset with all three new modelling elements, NewModTC, performed best, with regards to matching observed thermal electricity generation. Introduction of the forced aggregated small CHP production was the most effective new modelling element to increase the R2 to indicate a better fit with the overall trend that modelled thermal production followed the observed.A comparison between observed data and results from the existing modelling showed that thermal electricity production in general was much more temperature dependent and less price dependent in reality compared to the model. The new modelling elements showed incremental improvements to the overall modelling, as thermal production became more temperature dependent and less price dependent, i.e. approaching the trends of the observed data. However, the comparisons also showed that there remains some work to increase temperature dependency and decrease price dependency for the modelled thermal production further.The new model datasets resulted in more volatile prices in Denmark on average across all scenarios compared to the existing modelling. The increased temperature dependency was the main reason for this. Implementing new production profiles changed the available, low cost back pressure capacity, so that less was produced, compared to the existing modelling, during high load hours, increasing prices, and more was produced during low load hours, contributing to decreased prices. It is likely, but not shown here, that this was due to a new, flat distribution of CHP production capacity over the week s 168 hours. Overall, the new small CHP aggregation resulted in a moderate price reduction, as production was forced at zero MC, increasing production especially during the winter. The function for temperature dependent capacity correction showed to change the prices for certain hours significantly, but no overall increase or decrease for neither initially low nor high price hours. The prices changed mainly due to the function regulating available back pressure capacity down, increasing prices, or up, lowering prices for individual hours

A Threatened British Identity? Rethinking the roles of commemorations in 21st century Britain

I løpet av det siste tiåret har minnesmarkeringer i Storbritannias offentlige rom fått mye oppmerksomhet som et resultat av et økt fokus på inkludering av forskjellige grupper i samfunnet. Dette fokuset har utspring i debatter vedrørende Storbritannias forsoning med de negative aspektene og konsekvensene av dets imperie. Tema for debattene har vært den problematiske fortiden til noen av de som minnes gjennom statuer og andre minnesmerker, og deres syn på 'rase', imperium og kolonialisme. Det har utviklet seg et skille mellom de som ønsker å fjerne disse minnesmarkeringene på den ene siden, og de som ønsker å beskytte dem på grunn av minnesmarkeringenes betydning for nasjonal arv og identitet, på den andre. Denne masteravhandlingen utforsker forbindelsen minnesmarkeringer har til identitet, arv, og vår forståelse av fortiden, samt minnesmarkeringers viktighet og tilstedeværelse i det offentlige rom. Avhandlingen har også som mål å undersøke nødvendigheten av å holde debatter rundt minnesmarkeringene og de narrativene av fortiden som de representerer.In the last decade, commemorations in the public spaces of Britain have gained attention as a result of increased focus on inclusivity. This focus has emerged from discussions and debates about Britain coming to terms with the negative aspects and consequences of its empire. In the discussions, the focus has been on the problematic pasts of some people commemorated in statues and memorials in connection to their views on ‘race’ and empire. A division has developed between people wanting to remove these commemorations on the one side, and people wanting to protect them, because of their history’s significance to the persons’ heritage and identity, on the other. This thesis investigates the connection commemorations have to identity, heritage, and the past, and commemorations' significance in Britain’s public spaces. Moreover, this thesis aims to investigate the necessity of having debates about these commemorations and the narratives of the past which they represent

Doctors with Borders

This paper presents the real case of a military surgeon who is the only one working at a small hospital in Iraq. The military surgeon can only operate on one wounded soldier due to limited medical resources. The first wounded soldier to arrive is the enemy. The second wounded soldier to arrive shortly after the enemy is a compatriot. Both soldiers will die without lifesaving surgery. The military surgeon is ordered by his superior not to operate on the enemy. Under the Geneva Conventions, physician-soldiers are legally required to give medical attention impartially. The only exception is urgent medical need. Both soldiers, friend and foe, have an urgent medical need. Dual-loyalty dilemmas such as this one can arise for military medical practitioners when loyalty to patients comes into conflict with loyalty to third parties such as the state. In this paper, several solutions to the dual-loyalty dilemma are considered and rejected. Solutions to the dual-loyalty dilemma ultimate fail because they rest on the physician-as-healer model which grounds contemporary medical ethics. The view that the ultimate objective of physicians and medicine is winning battles is defended. Physicians are non-neutral and partial fighters who sometimes must do harm. Medicine is a weapon that physicians use to fight an enemy. The only relevant differences between a soldier and physician are the kind of enemy, location of the enemy, and the type of weapons used against the enemy. The paper concludes that physician-soldiers are doctors with borders. There is no dual-loyalty dilemma on the physician-as-fighter model. The military surgeon should obey his orders and not operate on the enemy. Implications of the physician-as-fighter model for mass casualty triage and physician-soldier participation in non-lethal weapons development are considered
