Syftet med denna uppsats var att undersöka om RTK ? tekniken (Real Time Kinematik) i framtiden kan komma att användas vid lotsning i Sverige, ombord på fartyg med begränsat vattendjup under kölen.  Squateffekten påverkar fartyg vid passage över grunda partier i farleder och i kanaler. För att minska ner på squateffekten så kan man minska ned på farten eller ändra fartygets trim. Studien har utformats utefter en kvalitativ metod, som handlar om att man väljer att bearbeta och analysera sin information genom att verbala analysmetoder används. Detta har genomförts genom att intervjua ett antal utvalda lotsar som både är insatta samt mindre insatta i tekniken.

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

This project details the process of converting and transferring a turn-based paper prototype to a digital real-time format. The projects goals were to see how well the original feeling could be transferred to real-time and how the transition itself went. The project have been completed with the help of the programmer Mikael Gullberg. The practical part of the project was executed between the dates of 25/4 ? 2/5.

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

The purpose of this thesis was to investigate how the distance between real estate manager and the managed item influenced the real estate management process. The overall real estate management within Lantmännen Fastigheter AB was investigated to give suggestions on how to improve the quality of the real estate management within the company. To do this, questionnaires, interviews and observations was performed within the Lantmännen Fastigheter AB organization. Real estate managers answered questions about their role as real estate manager, maintenance planning, decision processes, leasing and strategies within the company.The analysis of the questionnaires, interviews and observations showed that the real estate managers wants to rearrange their spent working hours around on working tasks to spend more time on the tasks that brings income and spend less time on tasks that are unsatisfying and unnecessary. The analysis also shows in which areas the real estate managers want more support and education and that they mostly work with unplanned maintenance.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.

In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

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.

The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

The study describes the problems with analysis of real estate companies after the introduction of IFRS. With the introduction of IFRS (2005) and specially IAS 40 the real estate companies get the ability to appreciate its real estates to real value. With the difference in the accounting, grows the question if it has become some differences for analysts with analysis and valuation of real estate companies. We also look into how well this new standard effect the real estate companies from the view of the accounting quality and its characteristics..

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Background: Our daily lives and personal interactions are increasingly featuring social media and social networks in particular. Topics regarding social media, its impact on society at large ? both on corporate as well as individual behavior ? has been the focus of many research papers. Personal use of social networks are regularly being mapped out by researchers aiming at clarifying concepts such as engagement, trust and interactivity, and mapped by companies seeking to maximize return on investment concerning their marketing efforts. The aim of our study is (i) to map how companies and/or organizations operating on the Swedish market use their company?s pages on the social media as a way of communicating with their followers and audience, as well as (ii) identifying whether ?Real-Time Marketing?, in our own definition, is used or not.Methods: The research methods used included both quantitative and qualitative content analysis.
