Manuell arytmitolkning och defibrillering prehospitalt för att minska avbrott i bröstkompressioner

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.

Arrende i ett föränderligt jordbruk

In 2006 the government assigned the Council of Cultural Affairs the task of making an update, consisting of 50 literary titles, to be added to the existing list called Alla tiders klassiker ? en klassikerserie för skolan (All-time classics suited for school).      The idea of ??a literary canon can be considered to be a tool for transferring socially, historically and culturally constructed norms and values ??from one generation to the next in order to create and maintain a common frame of reference. The common frame of reference affect the individual's thoughts and actions as well as their sexual desires and their own perception of self as a sexual being.

Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess

This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.

Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten

Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.

Meningsfull Fritid? : Några fritidshemsbarns tankar om sin fritidstid

During my practical training I have seen what after-school offers children. Large groups of children and little staff, often results in that the children had to play freely until they go home. Few activities are offered to the children and the staff is busy looking after the children and ensures that they are not fighting.The purpose of this study is to find out how children feel about their leisure activities and if they think they are being offered a meaningful leisure. The main research questions were:How do children experience their leisure-time?Do after-school offers children a meaningful leisure and is it the children's interests and needs that govern the activities and the environment?How do the number of children in the leisure group affect the leisure time?The methods to collect data in the study are observations and interviews.

Effektivisering av produktionsgrupp : Improving the efficiency of a production group

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Verifikation av verktyget aspect analyzer

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.

Rytmmodellen - Modell för lyckad Time Pacing

Problemställning: Vilka är de interna samt externa kritiska faktorer som skall tas hänsyn till, vid fastställandet av en Time pacing-rytm?Syfte: Syftet med uppsatsen är att klargöra vilka interna och externa faktorer som är kritiska, av största vikt, för fastställandet av en Time pacing-rytm i ett företag. Dessutom ämnar vi ordna dessa faktorer i en modell som skall hjälpa företag vid fastställandet av rytmen, vid användandet av Time pacing-strategin.Metod: Uppsatsen är genomförd med kvalitativ inriktning, och dess primärdata är inhämtat dels genom intervjuer med externa konsulter, dels genom intervjuer hos fallföretaget.Slutsatser: Vi har utrönt vilka de kritiska faktorerna är som påverkar Time pacing-rytmen. Detta har vi visualiserat i en modell, i vilken vi även rangordnat faktorerna kronologisk gentemot varandra. Således har vi fastslagit att det finns faktorer som är mer kritiska än andra vid fastställandet av rytmen, samt att det går att rangordna dem kronologiskt..

OSE och Linux : En studie om prestanda

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..

Mjölkkors behov av att ligga och att sova

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.

Indexeffekten : En studie gjord på Nasdaq OMXS30 och OMXH25

AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Anytime-whatever : Om narrativ struktur och temporal upplösning i Stig Larssons Autisterna

This essay is reading the Swedish author Stig Larssons debut Autisterna [The Autists] (1979) in the light of Gérard Genettes narratology and the time philosophy of Gilles Deleuze. The focus of the essay is time and how it is seemingly dissolved. The essay maps out a chronology of the non-chronological novel and from there discusses the breaking up of the empirical time. The essay uses Deleuze to explore the time-image of the novel to see how it is built up in the text for example by literary anyspace-whatevers. Hence the title, Anytime-whatever.

Den pedagogiska samlingen i förskolan : En kvalitativ studie om förskollärarnas tankar kring samling

The purpose of this work is to explore and illuminate the circle times function and importance of preschool by the pedagogue perspective and the circle time design in relation to children's age group composition. The study questions are:What is the purpose of circle time in preschool educational activities according to the teacher and how does the teacher look at his own role?How do the teachers plan, design and perform the circle time of small children and big children's section? What similarities and differences exist?This is a qualitative study based on interviews with four preschool teachers and observations of their circle times. Research and theories showed that the circle time is a social training, provide a sense of community and is a ritual that gives a good daily rhythm.The results of the study demonstrate that the circle time is an important routine that occurs for a short time daily in early childhood education. The circle time organizes and structures the day for both children and staff group.
