Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

Organizational change is hard to achieve, but if an organization doesn't change it might risk its own existence. Effective resource allocation and increased control of the internal production are examples of how organizations try to increase its competitive advantage. An ERP system (Enterprise Resource Planning) can help an organization to achieve this by providing management with direct access to a wealth of real-time operating information, streamlined dataflow, and making the company's business processes more effective. Like other IT-related projects, ERP investments are associated with large risks. Many projects failure during the implementation in one way or another.

Bakgrund: Studier har visat att dörröppningar samt rörelse av personal inne på operationssalen ökar mängden bakterier i luften. Vårdrelaterade infektioner är den mest förekommande komplikationen vid kirurgi och skapar onödigt lidande för patienten. Infektionsförebyggande åtgärder såsom ventilation i operationssalen har betydelse för att minska risken för att bakteriebärande partiklar ska kontaminera luften i operationssalen och åstadkomma infektion i operationssåret. Syfte: Syftet med denna observationsstudie var att studera hur frekvent dörrarna öppnades under pågående operation samt identifiera orsakerna till dörröppningarna. Metod: Data från observationer av 27 operationer har sammanställts och analyserats.

The aim of this thesis is to investigate how Bahamas, a magazine belonging to the antideutsche current in German left-wing politics, acted during a two year period between the summer 2001 and 2003. When explaining the anti-deutsche phenomena and the editors? politics it is common to take the currents own history-writing as a fact, thus presenting the development of the current as a reaction to outside factors and impulses outside. In this thesis it is stressed that the editors are far from only passively reacting, rather the opposite is true. I claim that the editors have a fixed ideology that they strive to implant in to certain parts of the radical left.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

To achieve a working collaboration in a big, complex organization where there are vast requirements on both quality and profitability is not always an easy task. An example of this is the organization that was created in the Swedish railway industry following a series of deregulations during the past 25 years. A partial market in this organization is the railway maintenance. In order to achieve a working collaboration between actors in this organization the so-called Purchaser-provider model (PPM) is presently used for the procurement of rail maintenance projects. Previous research has shown that this market-based instrument has clear positive effects regarding the cost-efficiency but hinders the collaboration.

AimTo validate the STOPP-8-questionnaire (S8Q), containing items from the SIH-questionnaire, against the criterion method accelerometry to estimate its capacity to assess 8 year old Swedish children?s physical activity (PA). Can it assess children?s physical activity? Can it differentiate the active children from the sedentary? If the answer is yes, how well can it do so? MethodData was collected during fall and winter the school year of 2008 - 2009 via the project STOPP-8. Out of 676 children at 12 schools in Stockholm area, 155 (boys n=72, girls n=83) provided complete questionnaire data and wore an accelerometer (Actiwatch 4) during 7 consecutive days which provided data for mean and median activity, time spent sedentary, in moderate to vigorous PA and vigorous PA.

Today Holmen Skog finds and selects suitable thinning stands using data on upper height and basal area. These figures are often based on basic forest data that has been updated with the help of growth prediction models. The problem is that these figures are not always correct. The aim of this study was to investigate if a combination of data from a profiling laser and a digital camera for low elevation photography, can be used for collecting data on number of stems per ha, tree species mixture as well as basal area weighted mean height and upper height for stands. The possibility to use these data to assess the need for thinning cutting was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.

Bakgrund: Perifer venkateter (PVK) är en allmän och rutinmässig åtgärd inom hälso- och sjukvården för att kunna lindra, bota och behandla genom att tillföra infusioner, läkemedel eller för att hålla en fri venväg. PVK består av ett främmande material som i kontakt med blod kan leda till att komplikationer som tromboflebiter bildas. Vid minsta tecken på rodnad, ömhet, svullnad, tromboflebit eller extravasation ska PVK avlägsnas. Syfte: Studiens syfte var att beskriva de senaste forskningsrönen kring sjuksköterskans omvårdnadsåtgärder för att undvika PVK-relaterade komplikationer. Metod: Studien är en litteraturstudie där resultatet baserats på kvantitativa och kvalitativa artiklar.

This diploma work project is a product development project which purpose is to redesign a braking system for a walking frame. The system that was developed diverges the force from the user to braking power, and includes a service brake as well as a parking brake. The most important components of the system are a grip handle on where the user holds on to and a braking handle on which the user operates the brake from. The system also includes a power transmission component, braking package and other mechanical components. All of the components wasn?t developed in this project, several off them has been reused from the existing system.This product has been developed to meet the requirements and standards presented from the principal, Ahlberg Leber.

For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.
