Skötselplaner – långa och tråkiga, men viktiga! De flesta av oss tycker nog att det är härligt att ge sig ut i ett naturreservat och strosa runt – uppleva de många typer av växter och djur som området erbjuder. Kanske får man se både fåglar, däggdjur, insekter och med stor sannolikhet får man vandra i både skog och äng. Naturreservat har detta gemensamt – de erhåller en stor variation av naturtypThere are a number of reasons to form a nature reserve - to preserve and promote biodiversity and to assure areas for outdoor life are two of them. To be able to maintain these values, it is important that an adequate management plan is established for the area in question. I have examined two nature reserves in the county of Lund, Sweden – Fågelsångsdalen and Linnebjer. Both of these reserves con

We are emerging into the IoT (Internet of Things) era as the IoT market is quickly increasing, giving us connected devices everywhere, from personal accessories to smart homes and even whole city infrastructures. The manufacturing companies need to stay competitive in this rapidly evolving market, so they need to minimize the price and optimize the Time to Market (TTM). When new versions of a prod

Liten blomma i backen, formad av bondens blod, svett och tårar En bit innan semesterparadiset Smögen, ligger en liten ö med mångårig historia. Här har marken odlats under många hundra år. På sommaren slåttrade man gräset, bar det till höbalar, och korna betade lojt på med utsikt över klipporna och havet. Störningarna var stora på gräsmarkerna, lien skar av växterna och korna betade, för många växWith the gain of productivity in farming the last decades, there has been great loss in species richness. Many plant species that have evolved and adapted alongside to traditional farming and benefiting to the managed land use, are now disappearing in great numbers. Three thirds of Sweden’s endangered plant species are those who thrive in managed grasslands like meadows and grazing areas. The trad

Suicide among young people are a serious problem worlwide as well in Sweden. The main purpose with this study was to examine and understand how suicide can be explained- to identify possible causes to suicide behaviour among young people. Through a qualitative approach, I interviewed six people who are working with young people in different ways. The main- result from this study shows that suicid

Genom införandet av lag (2006:45) om omvandling av fängelse på livstid (OmvL) skapades ett nytt frigivningssystem för livstidsdömda genom en rätt att ansöka om omvandling hos Örebro TR efter att ha avtjänat tio år av det utdömda livstidsstraffet. Omvandlingsprövningen består av fem kriterier, varav ett innebär en bedömning av om det föreligger risk för återfall i allvarlig brottslighet. Om konkretBy the passing of the Act (2006:45) on conversion of imprisonment for life (OmvL), a new system for the release of a prisoner serving life sentence was created, by enabling an entitlement to apply for conversion after having served ten years of the imprisonment. The adjudicate consists of five conversion criteria, one of which involves an assessment of whether there is a risk of a recidivism into

Denna uppsats utreder två förslag på ändringar i den svenska lagstiftningen om offentlig upphandling som presenterats av utredningen "Upphandling och villkor enligt kollektivavtal". Utredningen föreslog, bland annat, att det skall vara möjligt för upphandlande enheter att ställa mer långtgående arbetsrättsliga krav på inhemska leverantörer än de som använder sig av utstationerad personalThis thesis studies two proposed changes in the Swedish public procurement legislation put forth by the government inquiry, "Upphandling och villkor enligt kollektivavtal". The government inquiry suggests, among other things, that it should be possible for contracting entities to require higher labor standards by domestic tenderers, than by tenderers that uses posted workers. This negati

The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a

The objective for this master thesis has been to develop a mathematical model of the actuator parts of the fifth generation Haldex AWD system. The parts to be modeled are the DC-Machine and the pump. Also a model of the elasticity of the clutch has to be derived as well as a model for the hydraulic fluid. These models were then to be implemented in Matlab Simulink. The model was derived by means o

Introduction: Rockwell Automation needs to understand how a lean company wants to visualize different KPIs. Ambu wants to see the value of using such visualization in their company and the effect it might have.Thus the two parts fulfill each other's needs and are the perfect match. Purpose: The purpose of the master thesis is to identify essential KPIs in a medical production process and desi

Saving battery time for mobile devices has been a goal for the industry for many years. With the advent of smartphones, reduction of energy consumption is even more important since they consume a lot more energy than the generation of mobile phones before them. Consumers are demanding longer battery life and greener electronics. One way to meet these demands is to reduce energy consumption. In ord

The human motor control is both robust and stable, despite large delays and highly complex motor systems with an abundance of actuators, sensors and degrees of freedom. The cerebellum is thought help accomplish this by compensating for external loads and internal limitations and disturbances through adaptation, creating inverse models of the motor system dynamics. The cerebellum does also exhibit

The area of power quality has received more and more attention during the last decade. Poor power quality is a growing problem, especially for the industry because it has a negative effect on production efficiency, power consumption and equipment life-span. Active filters are one of the more widespread solutions to these problems. An active filter is often sized and installed to compensate a speci

The overall objective of this study is to describe, analyse and suggest improvements on existing automatic exposure control systems in selected network video cameras. Since an image sensor has a limited dynamic range compared to a real scene, it is necessary to automatically control the exposure level and thus adapt to the amount of light in the scene. This can be done by adjusting parameters such

A climatisation controller for a car with multiple objectives is developed, implemented and tested in simulations. The design focuses on electric cars and their specific characteristics. In this context the goal has been to fulfil common comfort and safety standards while having a low energy consumption. The main idea of the control in order to achieve this is to use a simplified model predictive

The growing use of wind energy as major energy source, has led to the construction of large wind farms. The control of such wind farms is typically separated into control at wind turbine level and at wind farm level. The wind farm controller assures that the wind farm produces the demanded amount of power, by providing set-points for the turbines in the farm. The local turbine control assures that

The main goal of this project was to use the Modelica features on embedded systems, real-time systems and basic mechanical modeling for the control of a two-wheeled self-balancing personal vehicle. The Elektor Wheelie, a Segway-like vehicle, was selected as the process to control. Modelica is an object-oriented language aimed at modeling of complex systems. The work in the thesis used the Modelica

Robotic science points to integrate the robot in the normal life and operations, with the scope to help humans and improve their performance. Haptic is the field that tries to insert the sense of touch in the computer applications. It is easy to understand the modern interest to mix the robotic with haptic. One possible problem with this configuration could be the delay in the communication betwee

This study is an attempt to take advantage of a cerebellar model to control a biomimetic arm. Aware that a variety of cerebellar models with different levels of details has been developed, we focused on a high-level model called MOSAIC. This model is thought to be able to describe the cerebellar functionality without getting into the details of the neural circuitry. To understand where this model

The motivation behind the thesis lies in some interesting results in the article 'Portfolio Optimization Applications of Stochastic Receding Horizon Control' written by James Primbs, regarding applying control theory to problems in the financial market. The purpose will be to implement a method called Model Predictive Control, MPC, for selecting optimal portfolio weights in two portfolios

The body shows impressive control capabilities in terms of the speed and the precision with which movements can be carried out under a wide variety of circumstances. The cerebellum and brainstem nuclei, including the cuneate nucleus, are believed to play a crucial role in this control. If these control mechanisms can be unveiled, this could yield important insights in not only medicine and neuroph
