Bakgrund: Sjuksk?terskans utveckling till omv?rdnadsexpert inom intensivv?rd kr?ver b?de en avancerad p?byggnadsutbildning och l?ng och gedigen erfarenhet inom yrket. I denna process g?r sjuksk?terskan igenom olika stadier vilka f?rklaras genom Benners modell f?r professionsutveckling, fr?n nyb?rjare till expert. Specialistsjuksk?terskor kan i stort utg?ra en viktig del i st?ttandet och handledningen av mindre erfarna kollegor, vilket fr?mjar s?ker v?rd och professionell utveckling.

I det här examensarbetet har jag tittat närmare på hur man med hjälp av en transformator kan höja signal/brus-förhållandet för en mikrofonsignal som förstärks av en förstärkarkrets. Arbetet baseras sig på en psykoakustisk brusmätning enligt standarden ITU-468-4.Ett bra förhållande mellan signal och brus är alltid eftersträvat i en krets. När signalen i kretsen är svag kan signalen i värsta fall försvinna i bruset. Arbetet kommer att titta på hur man definierar och mäter signal/brus-förhållanden på en förstärkare samt vad som påverkar signal/brus-förhållandet. Arbetet kommer visa att med hjälp av en spänningstransformering av en in-signal så kan ett bättre signal/brus- förhållande ut från en serie förstärkare erhållas..

Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

En av Ring P1:s ambitioner är att låta svenska folket få en röst i etern och i den offentliga debatten. Men är det verkligen svenska folkets röst som hörs i Ring P1? Vem är det egentligen som ringer in?.

BakgrundGenom livet a?r bero?ring betydelsefullt fo?r ma?nniskans va?lbefinnande. Vid bero?ring frisa?tts hormonet oxytocin som bland annat bidrar till sa?nkning av blodtryck och puls.

The data acquisition system COMET developed by Saab AB contains a unit for signal conditioning and A/D conversion, called KSM. The varieties in signal conditioning constitutes of a number of specific PBAs and maintenance as well as reconfiguration of these are complicated not to mention costly. This thesis has aimed to investigating whether the signal conditioning circuits can be replaced by a general purpose, programmable solution. If so, how can this be done? The development has been carried out by evaluating ideas through the use of a laboratory environment and has resulted in an analog design for laboratory purpose.

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

Genom att la?sa tidigare forskning om Generation Y, inneha?llsmarknadsfo?ring och om sociala medier under uppsatsprocessen fo?ra?ndrades problemsta?llningen succesivt, i enlighet med en abduktiv forskningsansats. Studiens fokus utvecklades fra?n att underso?ka alternativa marknadsfo?ringsmetoder vid marknadsfo?ring mot Generation Y till att omfatta pa? vilken social medieplattform Generation Y a?r mest mottaglig fo?r inneha?llsbaserad marknadsfo?ring.Syftet med denna studie a?r att hja?lpa fo?retag vars ma?lgrupp a?r Generation Y att rikta sin inneha?llsmarknadsfo?ring i ra?tt kanaler och pa? detta sa?tt spara tid och pengar. Fo?r att uppfylla syftet och besvara studiens problem samlades empirisk data in genom en webbaserad, kvantitativ enka?tunderso?kning som genomfo?rdes av totalt 301 respondenter, alla tillho?rande Generation Y.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

The wide distribution range of our boreal pine (Pinus sylvestris L.) provides a great variation in growing conditions and climate/weather factors that influence the wood development of the trees. A great number of extensive studies have been conducted over the years in order to clarify growth trends of this and other species over more or less wide-ranging areas. In this thesis effects of weather factors were instead compared between different forest stands from the about same geographical location. The effects of precipitation, temperature and frost on the year ring characteristics of pine were studied in the research forest of Svartberget Vindeln, in northern Sweden. The stands differed in site index and silvicultural treatment; fertile ? high stem density, fertile ? low stem density, poor ? high stem density and poor ? low stem density.

Insamlingsorganisationer anses ha flera anledningar till att efterstra?va la?ngsiktiga och lo?nsamma relationer med fo?retag. Att tilla?mpa relationsmarknadsfo?ring kan vara ett sa?tt att uppna? detta. Forskningen om relationsmarknadsfo?ring i kontexten av insamlingsorganisationer a?r da?remot begra?nsad.

Reformen Snabbare lagf?ring inf?rdes f?r att p?skynda r?ttsprocessen och effektivisera hanteringen av mindre allvarliga brott. Syftet var att minska tiden mellan brott och lagf?ring samt att effektivisera resursanv?ndningen i utredningsarbetet. Samtidigt har reformen m?tt kritik f?r att inskr?nka r?ttss?kerheten, s?rskilt n?r det g?ller den misst?nktes r?tt till f?rsvar och m?jligheten att ?verklaga.

The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..
