Dagens informationssamhälle har bidragit till att människor, maskiner och företag genererar och lagrar stora mängder data. Hanteringen och bearbetningen av de stora datamängderna har fått samlingsnamnet Big Data.De stora datamängderna ökar bland annat möjligheterna att bedriva kunskapsbaserad verksamhetsutveckling. Med traditionella metoder för insamling och analys av data har kunskapsbaserad verksamhetsutveckling tillämpats genom att skicka ut resurskrävande marknadsundersökningar och kartläggningar, ofta genomförda av specialiserade undersökningsföretag. Efterhand som analyser av samhällets befintliga datamängder blir allt värdefullare,har undersökningsföretagen därmed en stor utvecklingsmöjlighet att vaska guld ifrån samhällets enorma datamängder. Studien är genomförd som en explorativ fallstudie som undersöker hur svenska undersökningsföretag arbetar med Big Data och identifierar några av de utmaningar de står inför tillämpningen av Big Data analyser i verksamheten. Resultatet visar att de deltagande undersökningsföretagen använder Big Data som verktyg för att effektivisera befintliga processer och i viss mån komplettera traditionella undersökningar.

Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

Background: Previous research demonstrates that negative stress in the current situation is common among nurses working in emergency care. The stress is demonstrated to be associated with poorer provided care for patients and impaired health of nurses. Aim: The purpose of the study was to highlight nurses' perception of stress and their work for a good nursing care on an emergency care department. Method: An empirical design with qualitative approach has been used. Five semi-structured interviews were conducted with nurses and forms the basis of the results of the study.

Each year over 3000 children in Sweden lose a parent. The loss of a parent may cause some grave changes in a child?s life, leading to both mental and physical consequences. The purpose of this literature study is to examine the different ways in which health care personnel can better receive and relate to children whose parents are dying or have passed away.Data was collected through such sources as Pubmed, Academic Search Elite and Cinahl, which resulted in the inclusion of sixteen subsequent articles, ten of which were quantitative and six of which were qualitative. Thirteen of the said articles illustrate how children act in response to a dying or deceased parent and what measures were needed for them to move on with their lives.

Today?s electrical grid companies understand that better knowledge of and information about their grid can help realize a smart grid network. One way to gain better knowledge and information about the low voltage network is to install measuring equipment on the substation transformer´s secondary low voltage side that measures the low voltage network losses for that specific substation. By doing so, grid companies can, due to the calculation of the low voltage network losses, identify and address issues such as illegal power dissipation, unmeasured power outtakes, and unsatisfied technical documentation for the substations low voltage network.During 2012, Mälarenergi Elnät AB had a total electrical network loss (both medium and low voltage network losses included) of three to four percent of their total distributed electrical volume. Converting this energy volume into a monetary figure this accounts for a loss of around 30 million Swedish crowns.

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..

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

Sverige har länge haft en god kultur av öppenhet i den offentliga sektorn tack vareoffentlighetsprincipen. Men med allt större tekniska framsteg och ökade krav på datatillgängligheträcker den klassiska öppenheten inte längre till. Det finns redan mycket intressant offentlig data iSverige, men i de flesta fall är den antingen sparad i format som är svåra att avläsa digitalt eller fördyr att använda.I denna uppsats undersöks hur ett API kan utvecklas, användas och integreras med andra API:er föratt öppna upp ovan nämnda data på ett bättre sätt och göra den mer tillgänglig för potentiellaanvändare. Vidare undersöks också PSI-direktivets egentliga nytta och hur det tillsammans medoffentlighetsprincipen kan bidra till den nya öppenheten. Med koppling till denna uppsats har ävenen prototyp utvecklats för att ge exempel på hur man kan kombinera olika API:er för att visualiserageografisk data samt hur ett API kan byggas ovanpå visualiseringen för att göra denna data mertillgänglig..
