Sha Jun

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.

Verksamhetsstyrning: Utrikesdepartementets personalbostäder

The purpose of this thesis is to find means of control that secure cost efficiency regarding the accommodation for the employees on missions abroad of the Swedish Ministry for Foreign Affairs. Today the ministry?s cost for the employees? rented housing is 100 million SEK and there is a need of improvement in the control of these costs. A work method for organizational development will be used in order to reach the findings presented in the thesis. First we study the strengths and weaknesses in today?s control system.

Locus of control, syskonplacering och kön : Finns det några samband?

The purpose of this study was to examine if there was a relation between birth order, gender and locus of control. There where 162 participants in the study, 44 men, 115 women. Birth order was coded into three levels. There where no significant differences between birth order and locus of control. The result showed that female participants where more external when it came to locus of control.

Personlighet och Health Locus of Control : en korrelationsstudie med deltagare från Sverige och Tyskland

I denna studie har undersökts personlighet och Health Locus of Control hos 56 kvinnor och män i åldrarna 18 till 65 år, där 30 var svenskar och 26 var tyskar. Undersökningens frågeställning var: Är en eller fler personlighetsdimensioner i Fem-Faktor-modellen relaterade till i vilken utsträckning en individ har Internality, Powerful others eller Chance Health Locus of Control. En NEO-PI enkät och ett Multi dimensionella Health Locus of Control-skalan-formulär administrerades.

Field Horsetail Equisetum arvense L. Colt's-foot Tussilago farfara L. Stationary perennials: Dock Rumex L. Mugwort Artemisia vulgaris L. Dandelion Taraxacum F.

Robotstyrning med metoden Sliding Mode Control

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.

Chef över Erik men inte över Anna : påverkas företags styrning då inhyrd personal ingår i personalstyrkan?

Riskkapitalbolags påverkan på styrning i sina portföljbolag: En studie om utveckling av styrsystem i svenska Venture Capital finansierade företag.

The aim of this study is to investigate which management control mechanisms evolve in companies that receive funding from Venture Capital companies and why the management control systems evolve in the way that they do. A case study was performed on three Swedish high technology companies, that all received funding from Venture Capital companies for the first time in 2006. Merchant?s framework, defining all management control mechanisms as either, results control, action control or personnel control, was used to structure the study. Results show that the companies that received Venture Capital all increased the use of management control mechanisms within results control, action control and personnel control.

Health Locus of Control och impulsivitet i relation till träning : en studie om universitetsstudenters träningsbeteende

There are many aspects which must be taken into consideration when studying individuals? need of exercise. The study investigates if impulsivity and Health Locus of Control affect the continuity of physical practise. The main presumption was that individuals with high impulsivity, high Powerful Others and high Chance Health Locus of Control, would have a significantly harder time to maintain a continuous physical activity. The survey used two standardized tests to measure impulsivity and Health Locus of Control and in order to be able to measure the insensitivity and the periodicity of physical exercise, a test was developed by the authors.

Klassrumskommunikation och lärande : En studie med fokus på kommunikationsmönster, frågornas roll och uppföljning av elevuttalanden i klassrumskommunikationen

The purpose of this bachelor's thesis is to examine how public libraries in Sweden handles their weeding procedures. A series of questions are asked: How does libraries in Sweden motivate weeding? What principles constitutes the procedure of weeding? Which aspects are given most importance when weeding is decided. How does views on weeding differ between libraries of different sizes? How does longer or shorter professional experience influence the view on weeding? The study was done through an online questionnaire which was sent to a number of staff members on different libraries via e-mail.

Interorganisatorisk styrning av leverantörsrelationer inom lågprismodebranschen: -En fallstudie av lågprismodeföretaget BikBok

This thesis concerns the control of outsourced interorganizational buyer-supplier relationships in the low-price fashion industry. A qualitative case study has been performed on two supplier relationships of a low-price fashion company. By identifying specificities of the industry and relating them to control problems and their implications on control solutions, the thesis has established a relation between industry specific characteristics and the way companies in the industry control their supplier relationships. The analysis is based on a theoretical framework created by Dekker (2004). Amongst other factors, the difficulty to define, quantify and measure the design variables of a fashion good, the high heterogeneity between individual products and the difficulty to predict the trend based demand, create high coordination requirements as well as appropriation concerns solved through extensive formal control.

Modellbaserad prediktiv reglering av en dieselmotor med variabel geometriturbin och återcirkulering av avgaser

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.
