Spill från rundbalspress med och utan knivar :

When harvesteing ley there is always mechanical losses from the harvest machines. During the last years the roundbalers with knives,cutting the material-are more common, This use increase the mechanical losses of material. MATERIALS AND METHODS The roundbaler which used in this test was a Krone Vario Pack 1500 Multi Cut. This roundbaler has 17 knives. The theoretical length of cut was 64 mm. During the test we stretched a rubber tarp under the balechamber and collected the materials which fell down from the balechamber.

Simulation driven design : An iterative approach for mechanical engineers with focus on static analysis

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Trådlösa nätverk i hemmet : Säkerhetsmedvetenhet och utbildningsbehov

Abstrakt Social Engineering är konsten att manipulera människor, för att på så sätt vinna deras förtroende. Med hjälp av detta förtroende kan attackeraren sedan kringgå säkerhetssystem och få tillgång till organisationers information. Vi har i denna uppsats genomfört elva intervjuer på tre stora organisationer med både IT-chefer och övrig personal. Med dessa intervjuer har vi sedan försökt få en bild av hur medvetenheten ser ut samt vilka åtgärder organisationerna tar för att förhindra Social Engineering. Med denna uppsats vill vi belysa den ovisshet som råder kring Social Engineering, men även farorna och hur effektiv en attack av denna typ kan vara.

Sjuksköterskors kommunikation med patienter som vårdas i respirator : Nurses? communication with patients during mechanical ventilation

Aim: The aim of this study was to describe intensive care nurses? experiences communicating with patients during mechanical ventilation.Methods/design: A qualitative interview study. Interviews where analyzed using descriptive content analysisSetting: Nine intensive care nurses from two different intensive care units were interviewed using a semi structured interview guide.Background: Past research has shown that patients during mechanical ventilation in the intensive care unit, feel very vulnerable and the helplessness of being unable to speak. These patients feels that they are completely dependent on the nurses and their competence. It has been shown to be very important that the patient feels included, acknowledged and respected.Results: The analyzed data resulted in a theme; through communication strive to preserve patients´ dignity and three main categories; create relationship to the patient, minimize patients´ vulnerability and don´t give up.

Reverse Engineering : En jämförelse mellan företag och forskare

Användning av mjukvaruverktyg när reverse engineering utförs är ett måste för att få ett användbart resultat enligt Hainaut (2002). Kudrass m fl (1997) visar på brister som kan uppstå när mjukvaruverktyg används. Gemensamt för de forskare som har studerats i detta arbete är att de hävdar att företag saknar kunskap för att utföra reverse engineering med mjukvaruverktyg. Har forskarna rätt i att det saknas kunskap eller har företagen mer kunskap än vad forskarna tror? Då dessa forskare har en klar koppling till tillverkning av mjukvaruverktyg så är eventuellt inte deras påstående opartiska och därför är det intressant att se om deras påstående stämmer med verkligheten.

Kommunikation hos respiratorvårdade patienter : Upplevelser hos patient och vårdpersonal samt analys av samtal med och utan röstgenerator

?Studies have shown that patients receiving mechanical ventilation in an intensive care unit (ICU), who are entirely dependent on the nursing staff, often experience frustration due to a temporary loss of the voice source. Limited communication is an important factor contributing to patient discomfort. Nursing staff also report communication as frustrating and difficult.The aim of the present study is to introduce a neck-type electrolarynx as a communication aid in an ICU, to study the nursing staff experiences of communication with tracheotomized patients receiving mechanical ventilation, and to examine the patient´s experiences regarding communicative abilities. Communication between a ventilator treated, tracheotomized patient and members of the nursing staff was recorded and analyzed according to principles of Conversation Analysis (CA).The results show that several members of the nursing staff experience difficulties communicating with tracheotomized patients receiving mechanical ventilation.

Undersökning av Mekaniska Problem med hjälp av Datoralgebra

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Maskinskydd på rullriktverk

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.
