Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Automatic registration of dairy cows grazing behaviour on pasture
Information regarding cows grazing behaviour and time spent grazing can be of great interest to dairy farmers, since this information can indicate how well suited the pasture is to the cows. Feed intake at pasture is however challenging to measure. Automated systems for monitoring the behaviour of cows within dairy production have become increasingly important and relatively common. The aim of this study was to validate an activity measuring device (HOBO® G Logger Pendant Data Logger, USA), a triaxial accelerometer that registers the cow?s head positions during grazing, in order to see if cows? grazing behaviour on pasture could be distinguished from their non grazing behaviour.
Territoriella identiteter och fusioner : Regional identitet vid interregionala fusioner
Title: Territorial identities and fusions- regional identity by interregional fusions Level: Final assignment for Bachelors Degree in Social Science with specialization in Urban and Regional Planning. Major subject: Geography. Author: Mladen Krajisnik Supervisor: Carl-Johan Nordblom Date: 2009 May Intention: The main focus of this study is to verify the existence, or nonexistence, of local and regional identities. Considering the result regarding regional identities, this thesis will continue on to clarify if these identities are to be seemed as a threat or resource during fusions, and if so, how can one best manage these different identities.Method: Only secondary data has been used in this study. I've botanized amongst the literature that processes fusions, impact of culture, identities, regions, territory. Continuing on, the collected empirical resources have been compared to my theory, from which an analysis was able to be spawned and conclusions were drawn.Result & Conclusions: The thesis confirms different regional identities, although it does not treat the subject regarding the inner strength of regions comparing to one another.
Query expansion med hjälp av en elektronisk tesaurus i en bibliografisk online-databas.
In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.
Dress for success - by using multichannel marketing
Background and problem: Corporate Governance is a well-known phenomenon which has been the focus of plenty of research where the board of directors and the CEO have been regarded as important actors. What's affecting decisions regarding these actors has been debated whereas media has been pointed out of having an impact. To decide whether or not media can affect Corporate Governance have shown to be problematic whereas it exists divergent views regarding this. At the same time this relationship is more explored in other contexts than the swedish one, although this one is considered suitable for this. Consequently there is a motive for examining medias impact on Corporate Governance in Sweden. Purpose: The purpose of the thesis is to explain if media has an impact on Corporate Governance at an overall level.
Värdering och klassificering av finansiella instrument enligt IAS 39 ? konsekvenser för lagstiftning och företag.
Det har de senaste årtiondena skett en ökning av den internationella handeln vilket har medfört en internationell kapitalmarknad. Användningen av finansiella instrument har ökat och det har uppstått ett behov av enhetliga regler för redovisningen av dessa. Från och med år 2005 ska samtliga börsnoterade företag inom EU redovisa enligt IASB:s standarder. I uppsatsen studerar vi vilka effekter IAS 39 ?Finacial instruments: Recognition and Measurement? kommer att få för svenska börsnoterade företag samt svensk lagstiftning.
Volymmätare för tall- och grankott
This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.
Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning
In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.
Ökat flöde genom timmersorteringen vid Ala sågverk
Ala sawmill in Ljusne, Hälsingland, has increased its flow through the sawing plant during the last couple of years. The problem now is the sorting plant, as this part of the mill is now slower than the rest. A close analysis of the sorting plant was therefore necessary to be able to increase the flow through. The aim of the project was to find solutions that can lessen downtime and increase flow. The goal was to increase the flow from 650 to 925 logs through the sorting plant per hour.
Trombocyträkning hos katt : en ny metod
Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.
Energy analysis of a fruit drying plant in Adeiso, Ghana
The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit
drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying
process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity.
The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.
Kapitalstrukturens inverkan på företagsvärdet : - En kvantitativ studie av den svenska aktiemarknaden
Background: During extreme market conditions like the period during fall 2008 the discussion of what affects company value becomes apparent. The capital structure is the relation between borrowed capital and equity in a company´s financing mix. What impact changes in capital structure have on company value is a widely debated subject within the theory of finance. If a relationship between capital structure and company value exists the implication is that an optimal capital structure where company value is maximized also exists.Aim: The aim of the thesis is to study whether a certain relationship between capital structure and company value exists among selected stocks and companies listed on Stockholmsbörsens OMXS30.Implementation: With aim to fulfill the purpose of the thesis regression analysis has been performed among chosen stocks and companies. The empirical results eventuating from this have been analyzed from the view of elected relevant theory.Completion and results: We find that during normal market conditions a positive relationship between debt ratio and enterprise value (EV) can be established.
Kundanpassning av ett rehabiliteringsverktyg
To be able to move around without having to think about each movement is for most people amatter of course. Todays society contributes to a life at high speed where the sparetime is oftenspend doing somekind of sport, even extreme sports which earlier only a few people wheredoing. This leads to not only good health effects but also to more injuries. One of the mostcommon injuries is the knee injury.Capio Artro Clinic is a clinic specialized in sports medicine and particulary patients with injuriesin knee, shoulder, foot, hip or elbow. They perform a great part of all the crucial ligamentsurgeries in Sweden and has therefor also a lot of patients in need for rehabilitation of the knee.During the rehabilitation the load of the injuried knee is increased in steps.
Litteraturundervisningens olika skepnader
In this essay, I analyze the syllabus for Swedish with specific regard to literature teaching. I identify three different perspectives which carries seperate implications. First, a text-centered perspective, which tends to position the importance of the text as a part of a tradition. However, this seems to distance the reading from the reader, and place the importance of the reading event outside the student. The consequence might be that the student employs an instrumental reading which simply responds to a pre-set idea of meaning.
Kontrollerad gjutprocess för renare stål
In a multi-year project at Swerea Swecast AB studies on influence of dissolved gas on inclusions have been made. The knowledge about these parameters could be used to increase the quality of the final steel casting. The purpose of this thesis was to closer examine the impact of the oxygen level on inclusions.The questions asked were:? What was the amount of inclusions at different levels of oxygen?? What was the size of these inclusions at different levels of oxygen?? What does the inclusions consist of at different levels of oxygen?This was studied by measuring and sampling, sample preparation and microscopic analysis using an optical microscope and a scanning electron microscope (SEM). Measurements and sampling was performed at Smålands Stålgjuteri AB in Eksjö and at Swerea Swecast AB in Jönköping.
