Software keystroke logging : Automatisering av skydd mot software keystroke logging
This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the Operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.
Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar
As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.
Miljöklassningssystem : Skillnader mellan Miljöklassad Byggnad och LEED samt dess påverkan på fastighetsvärdet
A uniform environmental rating system for green buildings is demanded in today's society, where the requirements of the energy consumption for real estate are increasing. There are several different systems around the world used to rate buildings, all with different assessment criteria and starting points, which make it difficult to compare environmental rated buildings with each other.The purpose of this paper is to acquire knowledge about the differences between the Swedish environmental rating system Miljöklassad Byggnad and the American LEED, to discover which system is most advantageous. We also examine whether environmental rating affect the value of a property.Miljöklassad Byggnad is relatively simple structured, which makes it possible for private individuals to rate their property. LEED is better structured on the other hand in the case of environmental classification of commercial properties, because there are manuals for among others hospitals, schools and retail. The rating system for Miljöklassad Byggnad is good since the system seeks to fix the number of errors and deficiencies as soon as possible.
Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.
Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this Operating system.
Konsumentvänlig Energibesparingsmodell : Ett verktyg som hjälper småhusägare att sänka sina energikostnader
Energy awareness is growing among the Swedish population and a one?to?two-family dwelling can save energy. The purpose of this paper is to design a tool that helps these home owners reduce their energy costs.The paper develops a model that gives them an indication of how much energy they can save. For the majority of homeowners, the next step in the quest to reduce theirs is most likely an energy audit. Therefore, information to help home owners to get a good energy audit performed is included in the model.A prototype running the Operating system iOS is created and validated against existing models, as well as an energy audit. .
Användarorienterad design av anestesisystem
In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.

The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.
Varumärkesbyggande processer
Due to the globalization and the changes in the market, companies have now realized the importance of a strong brand. This has led to the phenomena outsourcing. The relation between the branding consultant and his or her client has changed. Earlier the consultants worked as a single unit and were given a task to independently accomplish the assignment. Today there has to be co-operation between the two parties.
Smörjning Av Lager
The work thesis was performed at Assalub a company which is situated in Åtvidaberg. The company works with developing, manufacturing and marketing equipment for handling of lubricants for light and heavier industry. The work thesis it is based on a inquiry Assalub got from MacGregor which is a company within cargo solution, from port to offshore system.For unloading grain and other material from the ship cargo it is used combined inlet feeder and screw conveyor, there the inlet feeder is drilling down through the cargo and feed the screw conveyer with material to further destination. At the bottom of the screw conveyer and the inlet feeder there is a bearing that keep the parts together. However the lubrication of the bearing must be made manually.
ISO 9001 : En fallstudie om hur de ständiga förbättringarna, som är införda i företagets verksamhetssystem, är anpassade efter medarbetarna
MPC is the company Exova Metech?s Operating system that contains all the information needed for the company's objectives and guidelines to permeate the company. How changes in the MPC should be communicated with the company's employees can be seen as problematic. Routines that have been changed in practice, the process owners do not always update in the MPC, it leads to that the employees can not ensure that duties are performed properly. It is therefore important that management takes its responsibility by providing updated information.
