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.

This essay is about the planning of Stockholm's border regions (areas on the outskirts of the city) during the first seven years of the 21st century. It describes how planning decisions are made in reality, in respect to a 'green' perspective. By describing what a "markanvisning" is (the right to negotiate with the city about a certain piece of land) and by discussing examples of what has happened with a hundred applications for markanvisning, this essay shows how Stockholm's border regions are planned. In the majority of cases it is the initiative of the future developers that begin the planning and construction processes. Research shows that the application to get a markanvisning in Stockholm does not follow a clear, structured system. However, the existing system in Stockholm does work and it seems like almost all the employees within the municipality, the politicians, and the future proprietors are happy with the current situation. Interviews have been held with key individuals involved in the planning process.

The increase in sales of the so called smart phones has meant that there has also been a requirement to determine new applications for which they are suitable. One of the largest platforms for smart phones is Android and the task of this thesis is to develop an application for a company that wishes to create interactive radio for the Internet. In addition to ordinary radio features, the company would like the application to be able to present images and a small web page called Canvas. The overall aim ,of this thesis, is to build a fully functional media player that is compatible with the majority of the commonly used Android based mobile units. To fulfill the overall aim, nine explicit goals were targeted.

Following study is about motivation from a student perspective. Based on the prescribed literature and published research, the concept and field of motivation have been illuminated. The purpose of the study was to examine how students in ninth grade perceived their educational motivation and what kind importance they considered it had for their performance in school. The study is also supposed to base upon the result; clarify the differences if any between schools. In an attempt to get a clear image of this a quantitative method in the form of surveys was made on two schools in the Stockholm region. One of the schools had a really good merit value, and the other had a rather poor merit- value. By choosing a quantitative method a relatively large number of students where able to participate and equally large quantity of statistics have been presented. The result point at motivation in the participating students in both schools can increase and decrease through different factors.

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

In today?s computerized society more and more companies choose to utilize new applications that can ease the way of handling the information. For many of us is imperative that the process as efficient as possible if one takes in consideration the size of savings that this new application can bring.The developer of the evaluated system is SYSteam AB Huskvarna and they are the ones that gave us this assignment. The application that we evaluate is SCM (Secure Connection Manager). It is already used today by big companies such as Telia and Ericsson to search for errors in telephone servers placed all over the country.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible.

Studien är en undersökning om hur olika delar av konsumentbeteendet bland applikationsanvändare ser ut. En applikation är ett program eller en tjänst som tillför en ny funktion i mobiltelefonen. Studiens syfte och problemformulering hur olika delar av konsumentbeteendet ser ut och utifrån det ta fram den typiske applikationsanvändaren. Som teoretisk referensram används en bearbetad version av Peter & Olsons (2008) Wheel of consumer analysis som vi kallar konsumenthjulet. Konsumenthjulet består av affekt och kognition, konsumenters omgivning och beteende.

Under de senaste åren har användningen av mobilapplikationer i smartphones ökat och kommer förmodligen fortsätta att göra det. Smartphoneanvändare ställer ofta höga krav och vill nästan alltid ha bättre prestanda i smartphones vilket driver utvecklingen framåt. Dock har många smartphoneanvändare klagat på att batteriet inte räcker till för deras användning. Enligt olika forskare är inte batteriet dåligt utan det är mobilapplikationer som förbrukar för mycket energi. De flesta studier som handlar om energiförbrukningen i mobilapplikationer fokuserar mycket på de tekniska aspekterna och det finns relativt lite kunskap om vad användare tycker om energiförbrukningen.

I have through qualitative interviews and analysis of previous research in the area searched answers to what tablets are used for in preschools and the reason why they are used in this way. In addition, it examines the similarities and differences there are in how teachers and children describe the use of the tool in preschool. The study is also looking for answers on whether and how the plates are used to develop children's scientific knowledge. There are six teachers and 14 children's statement that forms the basis for the analysis. The results indicate that tablets are used for two purposes.

ABSTRACT The main purpose of IT security policies is to protect companies against intrusion and unwanted spread of information. Statistics show that IT related crimes tend to increase and because of that it is important, from the company?s side of view, to be well prepared. The IT security policy is an important part of that preparation. A lot of the crimes related to IT can be deduced indirectly to employees at the companies where the crime takes place.

Our purposes with this essay was from the perspective of young people that has completed a stay at HVB-home, their parents and the social welfare secretaries get an apprehension on their way of looking at the purpose of placement in a HVB-home agrees with the comprehensive view of the placement. We also wish to get a picture of what is of important to change in this matter. How do they experience the reasons for the placement, goals and purpose? What positive and negative experience do they have from their placement? What is relevant to change when you look at the different parties' ways of looking at change/progress in this matter? In what different ways do the parties look upon collaboration and how does that effect the treatment? Our qualitative study is built upon interviews with the persons mentioned, upon educational visits to HVB-homes and upon interviews of staff at HVB-homes. The staffs opinion has also been compared with the other perspectives.

In order to be a good teacher according to preferences from outside the school area, there are many different voices to listen to. The different roles that are assigned for teachers are colliding with the latest research from the pedagogical institutions and therefore the role as a teacher of today is in a complex state of mind. Somewhere, between the traditional role of teaching and the moderating ideal image, reality is revealed in the ambivalent role of the teacher of today. In this pedagogical essay on advanced level we are focusing on obstacles that are hindering the moderating teacher?s role, to be fully developed in the classroom.

The present study origins from Diana Deutschs work with the octave illusion and investigates if musically trained subjects can give a more correct perception of the octave illusion if their visual senses also get stimulated in form of scores.Ten subjects, with over 20 years experience playing an instrument, participated in the investigation. The result shows that a more correct perception of the octave illusion depends on the educational level in scorereading. Four out of five subjects who valued their knowledge in scorereading as being good or very good reported that the score corresponded to what they could hear in the right ear, which is connected to the dominant hemisphere. When they were instructed to focus on both ears three of these subjects reported that the score corresponded to what they could hear in the left ear, but that they could not hear the lower tone in the right ear. As the scores for the right ear were equal for the identical soundexamples this perception could be an indication that stimuli are percieved as being complex and the interpretation is alternated to the non dominant hemisphere..
