Growing amounts of waste generation in remote areas without proper waste management systems is a problem to human health and the environment. The Amazon holds the biggest freshwater resources in the world, is a biodiversity hotspot and its communities are placed in distances that can take days by boat to be reached. A National policy with EPR instruments requires private companies to take-back pac

Världens sötvattensystemen är sårbara och har upplevt betydande miljöförändringar. Utöver direkt mänsklig påverkan, innebär klimatförändringar ytterligare påfrestningar på våra färskvattenresurser. I denna studie undersöks hur klimatförändringar har påverkat tidsperioden av istäckning i svenska sjöar och vattendrag. Observationer från över 750 sjöar och vattendrag i Sverige har analyserats, med viThe worlds freshwater systems are vulnerable and have experienced significant environmental changes. In addition to direct anthropogenic impacts, climate change poses yet another source of pressure on the freshwater resources. This study investigates climate change impacts on ice cover duration in Swedish lakes and rivers. In situ observations from over 750 lakes and rivers in Sweden were analyzed

Inom hjärnforskning önskar man ta reda på värdet för olika kemiska parametrar. Här beskrivs en metod som med ren matematik kan beräkna de optimala parametervärdena. Den bakomliggande kemin gav upphov till speciella matematiska egenskaper. Med hjälp av en egenutvecklad sats kunde det då visas att metoden alltid hittar den lösning som är bäst enligt den så kallade maxnormen.In this thesis, functions describing relations between chemical concentrations at equilibrium are studied. The functions have some parameters that are desired to be determined. Based on the properties of the functions, an optimization method will be proposed. Because of these special properties, it is appropriate to consider the residuals in the max norm, since then it is possible to show that the

This master thesis is written at the faculty of engineering at Lund University in collaboration with IKEA Industry. The aim is to analyze the potential in electricity production from excess wood biomass coming from production. The available biomass varies in form, quantity, size and moisture content. Various technologies, handling different kind of feedstock for electricity production were investi

Conditional Cash Transfer (CCT) programs aim to alleviate short term poverty and reduce intergenerational poverty by supplying targeted poor households with cash transfers contingent upon certain program parameters, such as school attendance for children. Evaluation on CCTs have found that such programs generally increase school enrolment and school attendance but its subsequent effect on labor ma

Nowadays, the use of digital signal processing is essential in various measurements of different machines. There has been many projects done at Sandvik AB on how to collect and measure data signals on the cone rock crusher. None of those measurements could present the correct data. The reason could possibly be due to the lack of theory behind the use of digital signal processing which this thesis

It is commonly understood that Intellectual Property Regimes are aimed at protecting private rights and in doing so sometimes neglect public interests. Historically IP systems were considered to allow authors or creators to secure certain monopolies on rights, hence in the 1970s and 1980s the concern over public needs came forward requiring the IP system to respond to it in a way that would stimul

Examensarbetet är utfört på och i samarbete med Imtech Ventilation i Malmö. Författarens avsikt har från början varit att skapa något som kan vara till stor nytta för företaget. Därför har examensarbetet utförts i nära samarbete med Imtech Ventilations medarbetare. Författaren har gjort en bakgrundsanalys av energikravs-läget i byggbranchen. Detta för att ta fram en validerad problemformulering ocThis master thesis is performed on and in cooperation with Imtech ventilation in Malmö. The author's intention was from the beginning to create something that can be of great benefit to the company. The master thesis has been carried out in close cooperation with the employees of Imtech Ventilation. The author has done a background analysis of the current excising energy regulations. This was

Bus lanes are being built as a measure to increase the share of public transport, thereby reducing congestion and environmental impacts. Evaluations are rarely made and the effects of the measures are therefore, in many cases unknown. It is currently unclear whether there are some general correlations between the Swedish cities where bus lanes have been built. This report examines the general tren

This thesis explores methods to find features that affect the start time of mobile apps. To help app developers improve performance over patch cycles, we implement an alarm pipeline in Apache Spark and tested it. This implementation is able to detect notable changes in the start time distribution and alert the developer. Spark is a scalable cluster computing framework, that proved well suited for

In the debate surrounding the genealogy of nationalism, the link has often been made between nationalism and the intellectual history of eighteenth century Germany — particularly to the German philosophers associated with transcendental idealism. Are such claims just, or are they simply the product of wishful thinking? If they are, to what extent? Is it fair, as Elie Kedouri once famously put it,

Aquaculture is the culture of plants, algae or animals that live in aquatic systems. It started being developed in the 50s and it has increased enormously since then. Aquaculture has the potential of mitigating some worldwide problems such as the global hunger and the fishing pressure. However, aquaculture is not perfect and it has several impacts over the environment. In order to assess all of th

The role of startups in today’s economy grows increasingly more important while more and more companies engage in open source software (OSS) development. Both startups and open source projects are sources of, and rely on, innovation. As startups are typically very resource constrained and open source potentially offers low cost labour and innovation sources; the intersection of startups and OSS is

Nära infrarött ljus (NIR) kan användas för att säkerställa djurfodrens näringsinnehåll Det är viktigt att kunna garantera att djurfoder innehåller rätt mängd näringsämnen, oavsett vilken sorts fettkälla (såsom vegetabiliska oljor eller fiskolja) som används vid fodertillverkning. Detta kan göras med NIR-teknik! För att djur ska vara välmående är det viktigt att de får i sig rätt mängd näringsämnThe aim with this master thesis was to investigate if a certain sow feed requires different calibrations in near-infrared analysis, due to if the sow feed have fish oil or AkoFeed as fat source. To investigate this, a basic sow feed mix was prepared and divided in 60 jars with 250 g in each. In 30 of the jars 0 to 15 g fish oil were added and in the other 30 jars 0 to 21 g AkoFeed were added. 2/

Continuous Integration is an approach to handle the complexity in modern software development projects. Instead of developing modules separately and then performing a time consuming phase of integrating all modules in the end of each project, it is possible to continuously test the compatibility of a single module as they develop. The company HMS Industrial Networks is a leading independent distri

Title: Virtual Reality as presentation tool for architects Authors: Adrian Norlund och Lisa Rask Supervisor: Fredrik Wikberg, Department of Building Construction, Faculty of Engineering (LTH) Question formulation: - Will the audience get a better idea of an object in VR compared to current presentation techniques? - What is most useful for architects, Oculus Rift, Google Cardboard or VR room (CAVE

When a website has critical points in time when the amount of visitors increases significantly within a very short time frame, it is extremely important for the underlying system to be prepared to properly handle these large amount of requests. In Emues’ case it’s about more than just keeping the services running, but also to improve on the user experience while purchasing tickets for events. The

This essay is focusing on the Chinese author Lao She’s work ErMa, a novel that is about two Chinese who move to England in the beginning of the twentieth century. In the novel there are plenty of cultural differences and prejudices between the English and the Chinese. This essay will focus on these and compare them with real, non-fictitious travel writings written by travellers to China and Europe
