The aim of this report is to discuss computer security in handheld computers and to find out the appropriate security level that must be implemented to be able to use handheld computers within the Swedish healthcare system. Most healthcare centers are using some kind of electronic journals for their patient´s data today, but there are still a number of clinics that are usingthe old paper-system. On a few places in Sweden the use of handheld computers at the clinics has already started, but in the United States the use of handheld computers in the medical area is already widespread and from this we can see a lot of different situations where it is useful and effective to work with handheld computers. The security demands on patient´s journals are high and regulated in both Swedish law and regulations from the National Swedish Board of Health and Welfare. The law does not have any substantial demands, but states that there should be an adequate security level based on the nature of the information and the costs.

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems.

Fazer Bageri AB has been choosen to represent a business corporation that uses handheld computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.

Applications for mobile devices, also known as apps, are today the backbone of a huge market where the company Apple is one of the key players. Apple develops, among other things, handheld electronic devices, which are powered by the operating system iOS. Through iOS, millions of customers get access to Apple?s App Store.During a period of two months, an app in the form of a game has been developed for iOS in the programming language Objective-C. The user of the app is presented intuitive menus and interactive graphical objects that seemingly obey physical laws.

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of  crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.

In today?s industry it is starting to get more and more interesting with wireless systems and solutions for applications. To be able to reduce the amount of cables drawn to various machines which takes both space and an extra fee for every cable drawn. Some systems might require the user to use a handheld device that is directly connected by a cable which in some machines might be inelegant for the user.The goal with this bachelor thesis is to develop wireless monitoring of the machine operators position that is working with heavy industrial machinery. The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about.

Due to the increasing international operations for the Swedish Armed Forces these new types of opponents needs new tools to cope with these commitments. A couple of years ago the Swedish Armed Forces had no non-lethal weapons, but today the Swedish soldier has a number of tools to choose from.The purpose of this paper is for the reader to get a presentation of which non-lethal weapons are used today by the Swedish Armed Forces and a sample of what non-lethal weapons are out on the market today. My main question is which non-lethal weapons do the Swedish Armed Forces? miss in their non-lethal capabilities set.I have collected information from a wide selections of sources like reports from the Swedish Defence Research Agency, the Swedish Armed Forces? own regulations and the Internet. The information is then processed and divided into five chapters: The development of non-lethal weapons, description of technologies, non-lethal weapons in the Swedish Armed Forces, Non-lethal weapons on the market and Results.This paper is limited to handheld, portable and man to man non-lethal weapons, all non-lethal weapons in the Swedish Armed Forces or on the international market are not covered.My conclusion is that the Swedish Armed Forces should acquire three 40 mm projectiles, one 12-gauge projectile and one TASER®..

The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.
