Artificial Intelligence and Terrain Handling of a Hexapod Robot

The focus of this master’s thesis has been getting a six-legged robot to autonomously navigate around a room with obstacles. To make this possible a time-of-flight camera has been implemented in order to map the environment. Two force sensing resistors were also mounted on the front legs to sense if the legs are in contact with the ground. The information from the sensors together with a path plan

Design of a Marine Protected Area in Öresund (Baltic Sea) and its effects on population of Atlantic cod (Gadus morhua)

Marine protected areas (MPA) have been widely used the recent years, as an alternative to the traditional management tools, in order to increase the yield and the health of a stock. The present study shows how cod population in Öresund would respond under different spatial and temporal MPA and how they will affect the gill-net fisheries in the area. For that reason, a simple model, based on logist

Flygsanddyners inre uppbyggnad : georadarundersökning

Sanddyner är landformer som bildas av vinden. Deras inre uppbyggnad utgörs av korslagringar och begränsningsytor som kan ge väsentlig information om det lokala klimatet och miljön vid dynernas bildning. Georadarundersökning som är en snabb, enkel och ickedestruktiv reflektionsmetod, ger en god bild av sanddynernas inre struktur eftersom korslagringar och begränsningsytor ger upphov till reflektoreDunes are landforms formed by the wind. Their internal architecture consists of cross beds and bounding surfaces that provide important information about the local climate and environment during dune formation. GPR is a quick, easy and non-destructive reflection method that provides an illustration of the dunes’ inner structure because crossbeds and bounding surfaces gives rise to re-flections tha

MicroRNAs in metastatic prostate cancer

MikroRNA-96 och sin roll i prostatacancer För att en cell ska vara hälsosam och kunna uppfylla sina funktioner så måste cellen producera den rätta mängden och rätta sorten RNA-molekyler och proteiner som är kodade i cellens DNA. På grund av detta så är genuttrycket strikt reglerat i varje cell. När det gäller cancerceller är balansen störd vilket innebär att cellen delar sig okontrollerat och bil

Calculation of Environmental Profits with Weight Reduced Core Material in Rotor Blades

Construction of wind turbines has increased these recent years and is expected to escalate more in the nearest future. The expansion of wind power as an energy source requires specific and comprehensive transport, when production is far away from the installation site. Generally, the development of turbines has gone towards bigger turbines with longer rotor blades. As the blades grow in length, op

Fast method to find sterically possible amino acid substitutions

With the growing pool of deposited protein structures, the need for structural analysis tools grows. In study of amino acid substitutions the variety of analysis tools is high; nevertheless, there is a lack of programs serving specific purpose, such as identifying if an amino acid substitution would cause a clash in the structure or not, given just the structure of the original protein. In this stAnalysing structural damage caused by changes in proteins In an organism, even only one single change of an amino acid can sometimes lead to disease, if the protein is a part of an important biological function. Because of that, it is important to study those changes and be able to predict if an amino acid substitution would cause harm. There are various ways a substitution can be harmful to a pr

Butterfly biodiversity in green areas of Malmö: quantifying the changes in the last 9 years

The decline suffered by grassland pollinators in the south of Sweden may have great consequences resulting in the loss of important ecosystem services. However, cities may mitigate this effect as parks and other urban green areas can act as refuges for high pollinator diversity. Here I try to assess the status of the butterfly populations in the city of Malmö using as a reference a study carried o

Batongmän och andra - en kvalitativ studie om maktutövning inom Kriminalvården

Kriminalvården är värld som många har åsikter om, men samtidigt har få kännedom om vad som verkligen sker däri. Makt förekommer i olika former och därmed är det viktigt att beskriva ur ett inifrånperspektiv hur maktspelet på en anstalt kan se ut. Syftet med den här studien är att undersöka om synen på institutionell maktutövning skiljer sig åt mellan gamla och nya kriminalvårdare. Jag har med hjä

Gas Purification of Exhaust Stream from Bitumen Storage

Bitumen är den tyngsta produkten från raffinaderier. Den är användbar som bindemedel för olika ytbeläggningar som t.ex. asfalt på vägar, takpapp m.m. Företag Nordic Waterproofing tillverkar takpapp i Höganäs och använder bitumen som en av de viktigaste råvarorna i processen. Ett förnyelsebart samhälle är dagens fokusmål för alla, inte bara enskilda personer, utan hela landet och hela planet måste Nordic Waterproofing is one of the largest roofing felt producers in Europe. One of the production facility is located in Höganäs (Sweden), which is specialized in roofing felt that are suitable for the nordic climate. Bitumen is a central component of roofing felt manufacturing that contribute several properties to the product. Due to the importance of bitumen, Nordic Waterproofing finds an addit

Det sjuka könet : en analys av den svenska medicinska diskursen kring intersex

Hur medicinen ser på och benämner intersexpersoner, d.v.s. personer som föds med kroppsliga variationer gällande könskaraktäristika, inklusive hormonella och/eller anatomiska och kromosomala variationer, vilka inte avläses som typiskt manliga eller kvinnliga får direkta konsekvenser för dessa människor i form av kirurgiska ingrepp och andra behandlingar. Ofta sker ingreppen på barn som inte har mö

Performance testing of in silico HLA typing tools using a validated next generation sequencing data set, and identification of HLA allele restricted tumour neo-antigens

Datoranalys av cellernas eget flagg-system kan bidra till forskningen kring patient-anpassade cancerbehandlingar Tänk dig att du zoomar in på cellytan utav dina celler. Något som du kommer lägga märke till är uppradade molekyler med små utstickande protein-stumpar (peptider). De står nästan som flaggstänger med viftande flaggor i olika former. Dessa ”flaggstänger” kallas för MHC molekyler och de The exceptionally polymorphic Human Leukocyte Antigen (HLA) genes play a crucial role in the immune system’s interplay with non-immune cells. Certain HLA alleles are known to have a strong disease correlation. There is a growing interest, within several research fields, in determining (typing) HLA alleles at higher resolution than what is possible today using standard laboratory methods. Within th

The role of SRC-like adaptor protein 2 (SLAP2) in receptor tyrosine kinase KIT signaling

SLAP2: A potential new strategy in fighting cancer Among more than 20,000 genes in humans, about 2% of genes encode a class of proteins referred to as kinases. A kinase is a protein, which transfers phosphate groups to proteins called substrate proteins. This process is named phosphorylation and almost all cellular behaviors are controlled by protein phosphorylation. Kinases mainly phosphorylate

Using Old Tires as 3D-Printing Material

Like with printers, material used for 3D­printing is what makes it expensive, especially if the printer is meant to be low­cost. Can used tires be the solution? This thesis proves that old tires can be turned into a usable granulate, with simple means. Then 3D­printing could be made accessible to people of lesser means.

Connode have developed a mesh radio solution based on 6LoWPAN, IPv6 over Low Powered Wireless Personal Area Network. By using this technology the communication unit on every meter is acting as both receiver and

Actors in Innovation

Innovation is gospel today. This also means a surge in popularity for the agents behind innovation; innovators. But who are they, exactly? Anecdotal evidence from both recent times and historical settings tend to emphasize remarkable individuals, who more or less alone created amazing things. By utilizing the SWINNO-database of innovations, this thesis examines how empirically prevalent the narrat

Optimization and Control Properties for a Dividing Wall Distillation Column

Dividing wall columns are single shell distillation columns which are thermally fully coupled. DWC has the ability to create three product streams from one feed stream. A simulation of DWCs is hard due to the complexity of the system. Unfortunately, there is no good software package that can be used for simulations. Instead a detailed flowsheet with the right components and good arrangement over t

Effektförluster från ventilationskanaler

I en allt mer energieffektiv värld så spelar allt fler av energiförlusterna allt större roll. Tidigare hade man samma förluster som idag från kanalsystemet men de totala förlusterna var större. När man nu har minskat andra förluster i huset får kanalför- lusterna en allt större betydelse i den totala energianvändningen, vilket leder till att det nu finns anledning att ta större hänsyn till dem. I To minimize energy losses becomes more and more important in a world where energy efficiency is a big priority and necessary if we want a future on our planet. The relative impact from ducting losses on the energy performance of the building was earlier so small that it was plausible to ignore them. Nowadays many of the other parts of the losses have been cut which means the air ducts now might st

Malmököket - Andrum i staden med möten kring mat

“Alla har en relation till odling och mat, oavsett om man kommer från Somalia, Irak eller Nydala i Malmö.” (Jimenez, 2012). Visst är det så! Att mat är något som vi alla har gemensamt och som förenar människor har varit utgångspunkten för detta arbete. Projektet har resulterat i ett sprudlande matcentrum i Nyhamnen i Malmö. Här kan människor från stadens alla hörn och besökare utifrån samlas krinThe fact that food is something that we all have in common and that it brings people together has been the starting point for this thesis work. The project has resulted in a vibrant food center in the future city district Nyhamnen in Malmö. Here people from all over the city can gather around the People’s Kitchen and Diner, a wine bar, urban farming facilities, food markets and more. The inspirati
