Hur vet vi att det inte finns en annan planet i vårt solsystem bakom solen som alltid är dold för våra ögon? Eller om det fanns en planet där, hur skulle den i så fall påverka vårt solsystem? Dessa två frågor är motivationen bakom det här arbetet, som ger både intressanta och förvånande förklaringar till hur vi skulle märka av en extra planet. I projektet används ett datorprogram som simulerar plaThe motivation for the project is to investigate what happens if I add a second Earth in the Solar System and project it forward in time. I add an Earth mass planet (called Earth two) in the same orbit as the Earth on the other side of the Sun (i.e. six months ahead of the original Earth). I then investigate how the perturbation of the second Earth effects the Solar System in the short and the lon

Naturens resurser är inte oändliga och förnyas inte i samma hastighet som vi förbrukar dem. Genom att återvinna, minskar inte bara avfallsmängden som deponeras, utan råmaterial behöver inte förbrukas i samma utsträckning. I Sverige har vi idag en väl utbyggd återvinning där ansvaret för omhändertagande och insamling av avfall från hushåll ligger hos kommunerna, med undantag för de produkter som omEmeli Magnusson (2015) MVEK03 Natural resources are not infinite and are not renewed in the same rate as we consume them. Recycling outweighs a part of the consumption of resources, and the environmental impacts, resulting from the manufacture of new products. Recycling is an important part of getting a sustainable society, it brings us an opportunity to recycle material resources. This study exa

Conditional Cash Transfers (CCT) and microcredits are popular within the development community as poverty reduction instruments. Amartya Sen has proposed a holistic approach to development, poverty and inequality that does not see an increase in income as the aim of development. For this author, interpersonal inequality matters for the prospects to live a valuable life. Moreover, the concept of ha

Organizations are looking more and more into BI in order to reduce their costs and increase their revenue as the effective use of BI can be the difference between bankruptcy and survival in times of financial uncertainty. Using BI, the user can detect trends in a quickly manner as well as analyzing the behavior of customers and make changes accordingly. Unlike private organizations, public transpo

Technology contributes to the modern economic development directly and indirectly, and it changes the operating system and working method during the economic transformation. Along with institutional reform and modern economic structural transformation of China, agriculture still plays an ineradicable role in the development of Chinese economy, and it is the cornerstone for countries with large pop

The aim of this study is to explore how care managers work with users/clients with dementia and partners in their ordinary housing. In four interviews care managers in two municipalities describe how they would act from two given scenarios from a perspective of conflict when the user’s partner and the care manager did not agree on the needs of the user. The study also focuses on the general work t

Due to the research scarcity in incentive travel and its environmental sustainability concerns, this thesis decided to concentrate on pro-environment issues related to incentive travel. The aim of this thesis is to investigate the current state of environmental concerns in incentive travel in China and find out how customers perceive pro-environment in an incentive trip. To achieve the research ai

Denna uppsats vid namn Att konsumera bekräftelse – Tinder och dejting i konsumtionssamhället har författats av Amanda Hjärtmyr vid institutionen för kommunikation och medier på Lunds Universitet. Uppsatsen har analyserat och problematiserat Tinder som en nytt dejtingmedium och till vilka anledningar användarna på applikationen använder den. Detta mynnade ut i att användarna främst söker efter bekr

Global Citizenship Education (GCE) has gained increasing conceptual popularity in recent years. The term has been used by governments, NGO’s and international agencies alike to promote a larger inclusion of global skills, values and attitudes in curricula across the world. However, GCE as practice is not a clearly defined framework and may involve many distinct themes and rationalities in its diff

The essay estimates the relation between population size and municipal costs. Whether the efficiency in service provision in municipalities is depending on population size is discussed in Sweden as well as other countries. The relation is measured using two measures for total costs and two measures for “fixed costs” associated with having an additional decision level. The result give some support

This thesis examines young people’s “lived citizenship” in the occupied West Bank and is based on qualitative research, including visual methods, carried out with a group of adolescents in Nablus. Young people’s ordinary experiences and everyday encounters with the notion of citizenship are at the core of my analysis, which adopts a micro-sociological approach in order to go beyond the “passive/en

This thesis evaluates the potential for machine guidance in winter road maintenance. The proposed benefits would be a reduction in material- or time needs. It should also reduce accidents with benefits for both property damages and personal injuries. The work methods and organisational structure of winter road maintenance is described through literature studies and interviews. The interviews are d

All Swedish citizens have the opportunity to continue their education on a university level. However, children with highly educated parents are far more likely to continue their studies after high school than others. The aim of this project is to inspire children to natural science, innovation and engineering at a young age. This to show what different possibilities the future has to offer, no mat

The six participants, two in Sweden and four in Denmark, interviewed for this thesis are all organizational outsiders: they consult organizations on how to create diverse workplaces. The empirical, qualitative material is analyzed within an interdisciplinary framework consisting of feminist, queer, anti-racist, affect and critical diversity theories. The focus of the thesis concerns resistance fro

Med anledning av att flera centralbanker baserar sin penningpolitik på ett inflationsmål, och att det med utgångspunkt från centralbankers agerande finns en större aversion mot deflation, i förhållande till inflation, undersöker vi i denna studie sambandet mellan deflation, inflation och ekonomisk tillväxt. Vi utgår från både teorier som menar att deflation är skadligt för ekonomisk tillväxt och t

A non-Granger causality test between bank lending and different economic performance measures represented by the real economy, real assets and the financial economy is conducted on Sweden. To capture for the effects of structural changes in the economy, a long period is analyzed (142 years) and two types of tests are made, one for the short- run and one for the long-run. The main findings are that

Sandvik SRP has earlier studied a new way of calculating the cost in crushing and screening the results was a satisfactory, Sandvik SRP is now ready to go further in this study. The purpose of this study is further develop of the earlier adopted generic cost model earlier developed by Heyman and Lindström in order to calculate the cost per metric ton within the world of crushing and screening.

Ungdomsarbetslöshet är ett ständigt återkommande samtalsämne. Sverige har en historia med låg arbetslöshet, lägre än Danmark. På 1980–talet införde vårt grannland den berömda arbetsmarknadsmodellen flexicurity och detta förändrade situationen. I Sverige är det lagen om anställningsskydd (LAS) som är kärnan i den svenska arbetsmarknadsmodellen. Lagen kom till för att skydda arbetstagare och ge en

In this thesis it was investigated how accurate the futures predict the spot prices and characterizing the futures risk premium on the German electricity market, which currently undergoes an energy transition. This was conducted twice, with realized data and with data from an own developed model. The realized spot price data and futures were obtained from the European Energy Exchange. The methodol

Runge–Kutta methods can be used for solving ordinary differential equations of the form y0 = f(t, y) with initial condition y(t0) = y0 and where f : R x R^m -> R^m. The idea is to find a method that is efficient to implement. But it is also important for the method to be of high order and be stable. Diagonally Implicit RK-methods reduces an sm x sm matrix to s systems of m x m linear equations. Si
