Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

This report is the result of an investigation of the possibility to use RFID-technology in a producing company. The investigation is focused on a flow between the company?s producing subsidiary company in Lithuania and its main facility in Sweden.RFID is the abbreviation for radiofrequency identification. The RFID-technology forms the base of a system with wireless information transmission between an object to which a transponder, also called tag, has been attached and a reader. The information is transmitted by radio waves and the system is equipped with software that can digitalise the radio waves.

In December 2004 an earthquake coursed waves that hit Thailand. Over 5000 people died, and Sweden was the tourist country that has been effected the worst. The catastrophe precipitated Sweden in crises and the demand became high for Swedish government to act. Swedes followed the development via media, why media became the crucial element for how the public perceived politicians? acting.

  During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today?s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions.

The aim of this study was to see if an increased amount of gas could be seen in the small bowel of cats subjected to trauma and if measuring the amount of gas could be of any use in the clinical evaluation of the patient. When the peristaltic waves in the small bowel decreases due to neurological damage or chock the microorganisms of the gut grow in number and possibly produce more gas and toxins. When the cat is stressed it can swallow more air then usual, and the air that is in solution with the chyme in the lumen of the gut separates from the ingesta. When the bowel isn?t moving it becomes easier for bacteria and toxins to penetrate the wall of the gut, and then get access to the bloodstream.

This report describes what wireless local area networks are and the use and configuration of them. These WLAN as they also are called can be used both in new installations and expansion of existing networks. Further on this report reveals security in this area. Security is incredible important in all networks not at least wireless because you don?t have to be in the environment physically to get the information, you only have to be in the coverage area that can be several hundred meters.

Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.

Seabased Industry AB develops system for extracting electrical energy from ocean waves with a Wave Energy Converter (WEC). The components is bought from subcontractors and then assembled into wave energy converters, buoys and marine substations by Seabased. In the future Seabased will produce more of the components themselves to reduce costs and to have better control over tolerances. The production line will also include the painting of the WECs and substations, which is performed in a painting line.The purpose of this thesis work is to study what is required to build a painting line, regarding the types of stations, transporting types and the space needed. This will result in layouts for the painting line.To receive the necessary information about production theory and corrosion and surface treatment, literature concerning this area has been studied.

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

Ultrasound is a diagnostic aid often overlooked by the veterinary practicioner who works with farm-animals. However, it?s use increases, particulary for breeders where ultrasound has long been used to evaluate ovaries and to diagnose pregnancy or disturbances in reproduction. There is much knowledge in how to examine ovaries and uterus by transrectal ultrasound, but when it comes to doing ultrasound of other organs in the abdomen the knowledge is more limited. Cows are very large animals, so it is not possible to examine everything inside the abdomen with ultrasound, simply because the ultrasound beam has a limited penetration. There is also lots of gas inside the gastro-intestinal tract of a cow, mainly in the large intestine and the rumen, and that makes it impossible to examine the organs behind the gas since the ultrasound waves are reflected when reaching the soft tissue-gas interface.

The paper contains comment, clarification and criticism, even constructive criticism, of some theses that have been put forward by Laurence Bonjour in his In Defense of Pure Reason.It presents a concept of experience that deals with the relation between cognizer and object of experience that has a great similarity to that of Bonjour. Through analysis it is shown that the concept of a priori entails that Bonjour has two concepts of a priori, a narrow and a broad one. The narrow one is, in my own words: According to moderate rationalism a proposition p is a priori justified if and only if you apprehend that p must be true in every possible world. This doesn?t mean that Bonjour doesn?t believe in an epistemological, metaphysical and semantic realm.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

In the years between 2012 and 2014, Burma has been shaken by waves of violence against Muslims which has resulted in destroyed mosques and shops, at least 140 000 displaced and 200 killed persons. The person who is said to lay behind this violence is the Burmese Theravada monk Ashin Wirathu. Being the founder and leader of the radical Buddhist movement 969, he has been accused of indirectly motivating violence against Muslims and has been portrayed with titles such as ?The face of buddhist terror?. This essay investigates the relation between Wirathu and the anti-Muslim violence by applying the method of content analysis on a speech of him.

The power consumption has grown rapidlyin the last decade. Fossil fuels and theneed for alternative energy sources aregreat. Ocean waves are a renewable andsustainable source of energy that hasbeen relatively untapped. At UppsalaUniversity research and development havebeen done for several years. Severaltypes of wave energy converters (WEC)have been created.
