Design of an Energy-Efficient Climate Control Algorithm for Electric Cars

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

Samverkansarbete i socialtjänsten - En studie av de hinder och problem som finns för socialsekreterare i samverkansarbetet med andra aktörer i ärenden rörande barn som far illa eller riskerar att fara illa.

The goal of this study, through the use of mainly an organizational theory perspective, is to examine the problems and obstacles in the cooperative work between social workers and other social actors in cases involving children at risk. The aim is to highlight problems that exist in social secretaries cooperative work and to find ways to understand them. The result showed that poor professional in

SUPPLY CHAIN FINANCE A Buyer-Centric Supplier Payables Financing Initiative

With an increased importance of working capital management and supply chain risks, supply chain finance has gained an increasing interest from organizations across the world. A buyer-centric supply chain finance solution can create a ‘win-win’ situation for buyers and suppliers, by allowing buyers to extend payment terms and suppliers to get payments in advance. This allows both buyers and supplie

Force Controlled Grinding-The Cutting Edge

Sharpening knives by hand is both time-consuming and exhausting, and may still not always yield perfect results. This thesis investigates the possibility of sharpening knives with the use of a force-controlled industrial robot, regardless of the knifes shape. The procedure is performed by first identifying the shape of the knife, using Matlab Simulink to simulate the identifiation; two different t

Model Predictive Control Based Energy Management Algorithm for a Hybrid Excavator

The Volvo Group has an ambitious plan to efficiencies its construction equipment vehicles with an introduction of a hybrid engine. This Master thesis is based on, as a first approach, to control the energy split in a hybrid construction equipment vehicle (HCEV) with the control strategy Model Predictive Control (MPC). The work is divided into two main parts, where the first one is to create a piec

Object Oriented Automation Systems

This master's thesis is about the implementation and evaluation of a small object-oriented automation system. By using a realtime Java VM from Jamaica, a sheet feeding magazine from the machine Tetra Aptiva Aseptic has been controlled. The expectations included to achieve more structured and safer programming, better documentation through UML and to separate application developers from develop

Model-based Friction Compensation for the Furuta Pendulum using the LuGre Model

Friction is present in all mechanical systems and causes a wide range of problems for control. The development of friction models and methods to account for friction in control has been an active research area for many years. A promising friction model that is capable of describing a wide array of observed friction phenomena is the LuGre model. This thesis deals with the application of friction co

Control of a Gantry-Tau Structure

Todays, industrial robots don't correspond to the needs of the Small and Medium sized Enterprises (SME). Indeed, industrial robots are in many cases too hard to program or too expensive to be used by this kind of enterprises. In order to respond to this need, a European project was created, regrouping five major European robot manufacturers and five leading research institute and universities,

Unga män och maskuliniteter

The environment surrounding us affects our sense of ourselves, although it isn’t something static or permanent, but rather predetermined by our perception. What we wanted to explore with this study was how men were influenced by their environment in relation to their identity development, and in what way they felt social pressure from the society. Therefore our purpose of the thesis was to investi

Relatedness and competition between caterpillars of Maculinea alcon within host plants

Competition between related caterpillars on host plant The Alcon Blue is a butterfly with a parasitic lifecycle. The butterfly starts its life on the Marsh Gentian were the caterpillars feed on the seeds within the flower bud. Several females lay eggs on the flower, which could mean that related caterpillars could potentially compete for the resources within the flower bud as there is a limit to

Deriving and implementing a model of the fifth generation Haldex AWD actuator

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

Optimal Pairs Trading Using Stochastic Control Approach---A Critical Evaluation

As of date, quantitative trading methods are a strong growing niche of trading. More and more sophisticated models are employed to chase investment opportunities. The question is whether this is over-engineering and if it adds value to practitioners. We have found an interesting quantitative pairs trading strategy that belong to the family of relative value strategies. The studied stochastic contr

Study of Proton Emission in Complex Nuclei

In a recent experiment, the partial half-life (t1/2) of proton emission from the Iπ = 19/2- state of 53Co was accurately measured. A previous estimate is t1/2 ~ 17 s. The purpose of this thesis was to explain this decay and give a theoretical estimate for the dominating hindrance factors. The angular momentum J in 53Co is coupled to J = 6 for the neutrons, and J = 7/2 for the protons. All of this

”Region Skåne är sjukvårdspersonalens värld” - en kvantitativ studie om kuratorns roll inom Malmö psykiatri

The aim of the study was to examine the role of the social worker employed within Malmö psychiatry regarding the social worker’s status and impact on patient care. The social worker’s role within hospital environment is a topic that has been examined many times before. In 2014, Socialstyrelsen released a report about introducing a license for social workers employed within hospital environments. T

When money grows on trees-The case of beyond-compliance companies sourcing from the Amazon Rainforest

The Amazon Rainforest is in grave danger of disappearing for good, due to a number of harmful economic activities, including land conversion for cattle ranching and monoculture, as well as unsustainable and illegal timber production. It has been shown, however, that the private sector has a crucial role in redressing socio-economic problems, causing deforestation and degradation. To illustrate thi
