Timeliness cost for agricultural sprayers : weed control in cereal crops

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.

Whole grain wheat : effects of peeling and pearling on chemical composition, taste and colour

The EU-project HEALTHGRAIN has suggested a new definition for whole grain which allows a small part of the grain to be removed during processing. By removing the outer part or the grain the hygienic quality will increase but it is not clear how the taste and colour is affected. So therefore in this study three different debranning methods, peeling, pearling and polishing, which remove the outer parts of the grains have been used on common and durum wheat. The dietary fibre and ash content, as well as germination was analysed in untreated, peeled, pearled and polished grains. The decrease in dietary fibre and ash was higher in grains that had been pearled compared to those that had been peeled or polished.

Ekonomistyrning inom individ- och familjeomsorg : "Sen om himlen ramlat ner och alla har blivit funktionshindrade, det spelar ingen roll, för det ni hade innan ? det får ni nästa år ändå."

The purpose of the study is to describe how financial management functions within the individual and family care services in three mid-sized municipalities.27 interviews with managers and key personnel at three management levels in Örebro, Växjö and Jönkö-ping were conducted using a descriptive approach and qualitative method. In addition governing docu-ments and delineations in regards to these municipalities have been studied.The combined findings show that all municipalities have separate visions and control systems/models for their municipality with focus on management by objectives and politically determined goals, which in-clude economical measurements and requirements for the departments. Moreover, are also tracking sys-tems, which are described as following up on the results thru indicators and/or measurable goals. The municipalities utilize framework financials and budget processing on a high level and its timings appears similar in each municipality.Additionally the study has shown that there is a desire and aspiration to implement central economic goals in all three municipalities. The interviewees describe how they use their leadership to anchor, follow up and create participation in economic objectives and results thru instrumental and institutional leadership.

Implementering av Constant Fraction Detection vid avståndsmätning

This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.

Deep Green i oceana strömmar - en konceptstudie

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.

Inventering av internationella bullerskyddsåtgärder för höghastighetståg

Utvecklingen inom järnvägssektorn går mot snabbare och mer effektiva transporter, dock begränsas utvecklingen av att det krävs nya och mer utvecklade spår och tåg för att uppnå det. Med dagens infrastruktur och tågmodeller är hastigheter på 200 km/h det maximala. Behovet att öka kapaciteten och införa höghastighetstrafik i Sverige utreds i nuläget. Med höghastighetstrafik avses hastigheter på minst 250 km/h. Banverket har som förvaltare av järnvägen ett sektorsansvar för miljön och således även buller.

Konstruktion av patientsimulator för anestesimaskiner

A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

Vilken är den teoretiskt optimala toppdiametern på bokmassaved vid motormanuell avverkning?

The bioenergy market has been introduced relatively late in a perspective of the Swedish forestry. Nowadays branches and tops are used more frequently as bioenergy after harvesting. Therefore, it has developed a competitive situation between pulpwood and bioenergy. This situation has even established some questions. Two examples of these are: ? At what top diameter should the final piece of pulpwood be crosscut to get the best economically result? ? Should the top diameter, at the final piece of pulpwood, be crosscut at a thicker or smaller diameter than what is done today? The purpose of this report is to answer these two questions when the harvesting is made motor manually in beech stands.

Nationell datajournal : - Strategier inom IT-politik

In the society of information that we live in the knowledge of computers and computer system will have a greater influence than we may think. Discrimination is no longer exclusively a term that indicates lesser understanding of different cultures, the discrimina-tion that is at hand will be between ?the have and the have-nots?.This study is about the strategic methods and considerations that is of importance for planning, organizing and finally implement the work with national computer based patient documentation. The strategic planning has been done over a period of time where different actors all had their share of influence. The cost seems to be endless since it has increased after the actual program, in this case, Cosmic from Cambio Healthcare, entered the scene of healthcare.

Svenska hushålls vedarbete : en fallstudie i Umeåregionen

In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood. The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.

Testförares acceptans av aktiv gaspedal

Många och gedigna studier har visat på hastighetens betydelse för trafikolyckors uppkomst och skadegrad. Som ett led i Nollvisionen sattsar Vägverket på olika typer av ISA-system (Intelligent Stöd för Anpassning av hastighet) för att hjälpa förarna att hålla hastighetsgränsen. Denna studie är ett led i utvärderingen av det storskaliga fältförsök med aktiv gaspedal som under ett år bedrivits i Lund. Studien inriktar sig på att undersöka testförarnas acceptans av systemet. I arbetet har även ingått att utforma en modell för hur acceptansen bildas.
