In 2012 prostate cancer was the second most common cancer diagnose for men. The diagnosis is confirmed by pathologists doing ocular inspection of prostate biopsies and the specimens are classified according to the Gleason grading system. The main goal of this thesis is to automate the classification using Convolutional Neural Networks (CNN). With the introduction of Convolutional Neural Networks the
SAMMANFATTNING Apply Emtunga är ett företag som saknar struktur gällande sin orderprocess. Examensarbetets syfte är därför att kartlägga företagets orderprocess samt klarlägga vilka problem som uppstår i samband med denna. Examensarbetet ämnar därmed svara på följande tre frågor: - hur orderprocessen ser ut, vilka problem som kan identifieras i samband med orderprocessen samt vilka förslag på åtg
Sammanfattning Syftet med denna uppsats är att undersöka om, och i så fall vilken, betydelse mångfald har när en plats marknadsför sig mot dess invånare. Då vårt studieobjekt är Helsingborgs stad har vi applicerat våra teoretiska resonemang på huruvida en organisation använder mångfald i marknadsföring för att främja goda relationer mellan kommunen och invånarna. För att undersöka detta har vi gj
De nickel-kadmiumbatterier som tillverkas vid Saft AB i Oskarshamn är uppladdningsbara och används vanligen som backup för strömförsörjning på sjukhus, flygplatser och till och med för hela städer. Ett problem för nickel-kadmiumbatterier är upplösning av kadmiumhydroxid, det aktiva materialet i kadmiumelektroden. Utöver förlust av aktivt material kan det upplösta materialet bilda ett tunt lager påIn this project, the properties of Cd(OH)2 in alkaline solution were studied. The processes of oxidation and reduction for Cd(OH)2 in alkaline solution are very complex and even though many studies have been done on the subject, it is not completely understood yet. It is from a Ni-Cd battery point of view, important to understand these processes to prevent loss of active material. The Cd-electrode
Hybridization between species can be avoided by behavioural or physiological mechanisms that act as prezygotic and postzygotic reproductive barriers. In sympatric areas, where species come into contact, the maintenance of species distinctness will depend on the strength of such mechanisms. In cases with recent secondary contacts of closely related species, barriers are often incomplete and the out
Parkinson’s disease (PD) is the second most common neurodegenerative disorder and is characterized by a progressive loss of dopaminergic neurons (DNs) in substantia nigra pars compact and accumulation of aggregated forms of the protein α-synuclein known as Lewy Bodies (LBs). LBs are present in surviving DNs and other regions of the central nervous system (CNS) in PD patients. PD patients also disp
The whole word has been getting somewhat familiar with the crisis that the newspaper industry has been experiencing. The past decade has seen print mainly absorbing finances with little to no profits, and the ever-growing digital not offering enough advertising revenue. Hence, the challenges managers face becomes clear: how can we innovate effectively when the current system is a loophole? Additio
Improvement of cancer vaccines with the invariant chain molecule Cancer is a disease well known to most people and has been treated for many years through irradiation and different drugs. However, many developing cancers are never discovered because they are killed by the immune system before they are established. Similar to elimination of intruding bacteria, the immune system should under normal
Biological drugs such as tumor necrosis factor (TNFα) blockers are very successful and effective in therapy of chronic inflammatory disease. These blockers bind TNFα and inhibit its pro-inflammatory function. But unfortunately, biological drugs are immunogenic and prolonged treatment triggers the formation of anti-drug antibodies and neutralizing antibodies (NAbs). This reaction is associated with
What decides how plant litter is decomposed, and by whom? Trees take up carbon in form of atmospheric CO2 from the air and use as building material as they grow. This carbon, locked in plant material, enters the soil carbon cycle via aboveground litter for example in the form of fallen foliage, dead trees, lost bark or via the plants root system as root litter or root exudates. Fungi and bacteria
Hur känner växter kyla? Växter har, precis som djur, utvecklat en mängd olika responser på signaler från miljön de lever i. En av dessa är vernalisering. Vernalisering innebär att en växt blommar tidigare om den utsatts för en kalla temperaturer under en längre period än vad den annars skulle ha gjort. I detta projekt har vi kollat närmare på gener involverade i denna mekanism. För att vernalise
The Pacific marten (Martes caurina) is thought to be a forest specialist closely linked to older forests with high canopy cover and dense shrubs. It is therefore highly surprising that a small population have been found in the coastal sand dunes in Oregon, United States. The martens seem to be choosing this habitat even though large areas of older forests are available just next to the dunes. With
Does urbanisation make great tits clever? The expanding urban areas are changing the environment that the wildlife lives in. Most bird species avoid cities while some animals seem to prosper there. On the other hand, there are some species that live both in urban and rural areas without a preference for one. Such species are really interesting to study, because they can directly show the impact t
Tuberculosis (TB) is an infectious disease caused by a bacterium called Mycobacterium tuberculosis (Mtb). Infection occurs through inhalation of bacteria-containing droplets. After entry into the respiratory tract the bacteria mainly reside within macrophages in the lung by using different strategies to escape killing by the immune system. The attenuated Mycobacterium bovis strain Bacille Calmette
The fast food industry is one of the important and growing segments of the overall restaurant industry. At the same time, it is a very dynamic and competitive business where too many vendors are chasing too few clients.To maintain sustainable growth and long-term success it is crucial to meet consumer needs and offer value to them. In order to achieve this, fast food providers must first evaluate
This research study aims to examine why small business owners comply with rules and regulations within their industries. The purpose is to obtain a deeper understanding of legal obedience amongst small business owners. More specifically, what extrinsic and intrinsic motivations makes small business owners comply with the laws. This study is exploratory and is based on five semi-structured intervi
The purpose of this project was to gain knowledge of polyhydroxyalkanoates’ (PHAs’) ability to be fractionated and form miscible blends for different structures, by using the methods: solvent/non solvent fractionation and co-dissolving in 2-butanol.The outcome of the fractions and blends was evaluated with differential scanning calorimetry (DSC), size exclusion chromatography (SEC), Fourier transf
This bachelor thesis was performed at BorgWarner AB in Landskrona. The assignment was to investigate different methods for external measurement of a permanent magnetized DC motor speed in revolutions per minute when you have no access to the rotor. The task was to examine different measurement methods, to produce a finished circuit that converts the signal frequency to rpm and build a complete too
Building new wind farms is an important part in the transition to renewable energy. However these projects often require large investments, and the cost of upgrading the existing infrastructure - to allow for the connection of new parks - is a component that cannot be ignored. When several wind farms seek interconnections, they are forced to collaborate and financing the connection. This leads to
Do sick birds migrate at different times than healthy ones? The word migration comes from the Latin migratus that means “to change”, referring to how birds change their geographic locations seasonally. Birds migrate to escape from decreased food availability or harsh weather on their breeding grounds. They migrate to areas of high or increasing resources where they stay during the winter period b
