Årlig gödsling med NPK bäst för gröda, miljö och ekonomi
Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.
Igensättning av övre spalten i centrifugalpump
This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
Leder icke användarcentrerad systemutveckling till låg användbarhet?
Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.
Design och implementering av ett webbaserat personalhanteringssystem
Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.
Digitala kvitton och dess framtida tillämpningar
Consumers today leave a fragment of information when they pay with their debit and credit cards. The aim of our work is to investigate ways to design a concept of a system in which digitally stored information that today is fragmented among several different holders, can be assembled into a system and made available to consumers. In our study of how a system for financial flow of information should be designed, we intend to study the present situation and the attempts made to alter it into a more informative reality. We intend to investigate the flow of information when a consumer pays by card, and the possible solutions regarding the design and transportation of digital receipts. A majority of the information of our digital consumption is today handled digitally.
User Interface Design for Analysis of Sensor Systems
In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user interface for the C2SR-system was performed.
Shooting Target - Konstruktion : Product Development
The shooting sport is one of the most widespread sports in the world and it isbeing practice in most countries. Based on their own experiences, in competition -and hobby shooting, the client M4Solutions found a demand and need for ashooting target that is manufactured in Sweden.The purpose of the project has been to develop, with the help of Marcus Walldén,two shooting targets from idea to finished product. These two shooting targets,Plate Rack Target and Dueling Tree, would each be equipped with a mechanicalresetting system but will in the future have the ability to be provided with anelectronic resetting system.The project from the client was divided into two theses. One of these two, writtenby Marcus Walldén, focused on the tripod parts and the overall design work forboth Plate Rack Target and Dueling Tree. The thesis that is presented in thisreport have focused on resetting systems, the design of protective plates and otherperipherals for both shooting targets.This work has primarily been in CAD environment where design, constructionand development has been given free rein.
Prototyp av informationssystem för militärfordon
Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.
Från förberedelse till upplevelse : Hur användarupplevelsen i e-handel kan efterlikna upplevelsen från en fysisk butik med fokus på single brandföretag
SyfteSyftet med denna studie har varit att undersöka vilka delar av upplevelsen som konsumenten får i en fysisk single brandbutik som bör efterliknas och lyftas in i samma företags digitala butik. Det har även varit att se hur väl företag förmedlar sina kärnvärden till sina konsumenter i den fysiska butiken. Slutligen har det undersökts vad som är viktigt när det kommer till egenskaper, funktioner och upplevelsen generellt för konsumenter när de handlar online.ProblemformuleringVad som gör denna studie speciellt intressant är att de single brandföretag jag har undersökt bedriver egen fysisk samt digital butik där de säljer sina produkter, men de har även återförsäljare som säljer samma produkter och blir på så sätt deras konkurrenter. Eftersom dessa single brandföretag har ett varumärke och kärnvärden som de måste leva upp till kan de inte sänka priserna på sina produkter på samma sätt som deras återförsäljare kan. Skulle då lösningen kunna vara att försöka lyfta in upplevelsen konsumenterna får i den fysiska butiken in i den digitala butiken för att förmedla en bra varumärkesupplevelse?SlutsatsDenna studie grundade sig på en modell som beskriver hur en bra användarupplevelse kan skapas.
En vision om Enhetsskolans återkomst
I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.
Användarinvolvering vid systemutvecklingsprojekt i vården
Vårdsektorns IT-system fungerar inte optimalt ur användarsynpunkt då acceptansen bland de olika professionerna är låg. När IT-systemen inte klarar av att stötta vårdaktörerna i deras dagliga arbete så kan det medföra en rad olika följder så som stress, tidsbrist och minskad patientsäkerhet. Därför ser vi att IT-systemen bör utvecklas ut användarsynpunkt för att klara av att fylla sin funktion som ett hjälpmedel i vården. Denna uppsats ämnar undersöka hur användarinvolvering vid systemutvecklingsprojekt i vården kan utvecklas. Genom en intervjustudie så kartlades den nuvarande situationen i vården. Med detta som utgångspunkt har vi sedan föreslagit tekniker och verktyg som kan hjälpa leverantörer och beställare att förbättra användarinvolveringen vid implementering av nya IT-system i vården.Nyckelord; IT-system i vård, användarinvolvering, Participatory Design, systemutveckling.

BIM för landskapsarkitekter : virtuell design och kommunikation
The purpose of this thesis is to describe what Building Information Modeling, BIM, could mean for landscape architects, and also hopefully to make sense of the possibilities and problems of the system. BIM is about virtual design and is based on all consultancy groups in the design team modeling in 3D. Intelligent objects and metadata, such as price and material, are used. The project group has a common interchange format for simple sharing of information. To get an idea of how the situation with BIM for landscape architects looks like today, I collected information mostly through interviews.
Digital guidning på campus Alnarp : tekniska lösningar för riktad information till olika målgrupper
Today digital guides are most frequently used by the museum and tourism industries. They are also used for education purposes. They make it possible to distribute information and have it easily accessible. In addition to written information they add sound, pictures and videos which lift the whole impression of the visited place to a higher level.
A variety of systems currently in use today have been evaluated.
