Specifikation för ett visualiseringsverktyg för consumption modes i aktiva databaser.

Syftet med denna rapport är att ta fram en specifikation för ett datorverktyg som visualiserar händelseupptäckt i aktiva databaser.Konventionella databashanteringssystem (DBHS) är passiva i den mening att data är skapad, hämtad, modifierad och raderad endast när en användare eller ett applikationsprogram explicit angivit detta. Många applikationer, såsom process control och power generation/distribution networks, kräver en snabb respons i kritiska situationer, och därför räcker inte ett passivt DBHS till. För dessa applikationer måste man kunna definiera villkor som övervakas av databasen. När dessa villkor sedan uppfylls utförs specificerade åtgärder/handlingar.Consumption modes är ett svårt och komplext område inom aktiva databaser. Som ett resultat av detta finns ett intresse i att använda visualisering för att lättare förstå de olika consumption modes som finns.En prototyp utformades för att fungera som underlag vid de intervjuer som senare genomfördes.

Skadliga nollflödespunkter i Fortum Värmes fjärrvärmenät i Stockholm : En analys av dess förekomst och effekter

When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.

Informationskrigföring : den nya teknikens hot

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.

Small-worlds och rich-clubs bland bloggar : En nätverksanalys av den svenska bloggosfären under FRA-debatten 2008

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.

Kvinnliga nätverk - ett sätt att göra skillnad? : En fallstudie på nätverket Q80 och dess mentor program

Sweden is known to be one of the world?s most equal countries. Nevertheless, out  of  Sweden?s 262 listed companies, only seven  of  them  has  a  female  president, which  is  equal  to  3,4  percent. To  counteract  these  numbers  there  are  several  possibilities.  One  arrangement  that  is  highly  controversial     is  affirmative  actions.  But  there  are  other  options,  for  instance  more  and  more female  networks  are  starting  to  rise  and  many  of  them  also  offers  a  mentoring  program  where  the  mentee  gets  the  opportunity  to  learn  from  someone  with  more  experience.The  purpose  of  this  study  is  to  examine  what  difference  the  female  network  Q80,  with  focus  on  its  mentoring  program,  is  doing  for  the  mentee.  As  an  underlying  purpose  the  study  is  also  examining  what  visions  and  attitudes  the  management  and  the  mentors  is  communicating  within  Q80.  The  focus  is  mainly  on  the  visions  of  Q80,  menas  mentors  and  business  exceeding mentorship.  A  survey  has  been  carried  out  among  mentees  from  three  different  seats of mentoring  programs  where  they  have  answered  19  different  questions  regarding  their  time  as  a  mentee.  Furthermore  interviews  have  taken  place  with the management  of Q80  and  two  mentors.  The  results  are  analyzed  based  on  theories  about  gender,  women  in   management,  leadership,  mentoring  program  and  organizational structure.  The  result  shows  that  Q80i  as  a  source  of  inspiration  and  a  support  for  the  category  of  "career  women"  with  its  core  mission  to  strengthen  the  participation of  individuals  on  a  personal  level  more than  to  work  to  even  out  the  gap  in  the  Swedish  labor market.

Vasaskolan i Gävle 1865-1899 : en studie i social tillhörighet hos läroverkets elever

The conception of exhaustion was first used in the end of 1960 and was then used in a psychological context directed towards the working life. Eventually was the conception devided into two main categories: mental and somatic symtoms. Today research of exhaustion is mainly aiming towards recovering and returning to working life.This work sets out to analyse the importance and effects of social networks such as family, friends and professional relations in helping people who suffer from exhaustion to recover. The study is based on interviews with eith people who have suffered from exhaustion but today are recovered. To my aid I have used tree different questions: What part have the social network of family and friends ment to the recovery? What part has the professional relationships with doctors, therapists and curators ment to the recovery? How have you changed your life in order to maintain balance?The interviews pointed out the importance of the social relationships as support, feedback and understanding that the process takes time.

Acceptansgränsen för solceller i lågspänningsnät : Kan den ökas?

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

STUDENTERS INFORMATIONSHORISONTER: Användning av Google och sociala nätverk i informationsökningsprocessen

The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.

Inneklimatet på ett kontor : Undersökning av inneklimatet vån. G4 stadshuset samt kontor på Ånghammargatan

This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.

Mobilannonsering: Hur ett värdenätverk formas kring en ny mediekanal

Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.

I medborgarnas tjänst?:En studie om avregleringens effekter på ansvarsfördelningen mellan offentliga och privata aktörer inom tre samhällsviktiga serviceområden i samband med orkanen Gudrun

The essay's aim is to explain how responsibility distribution between private and public bodies, primarily within three important service areas, can be visualised in light of the fact that they have experienced different forms of readjustment. We have chosen to study this by looking at the restoration work taking place after the hurricane Gudrun swept across southern Sweden on January 8-9, 2005; and we have chosen to concentrate on the service areas of electricity- and telephone supply, and public transport. The responsibility distribution has been depicted by carrying out qualitative interviews with employees within both private and public bodies included in the restoration work. The conclusion produced is that there were obscurities in the formal responsibility distribution between private and public actors taking place in conjunction with the hurricane restoration work.In a deeper analysis, the result can be explained by a ?several hands? problem arising since the number of actors has increased as the public sphere has adopted leadership forms influenced by the private business sector.

"Man vill ju se bra ut" : En kvalitativ studie om ungdomars syn på sociala medier

This thesis examines young people's thoughts about their presence on social media. With asocial constructive approach the study focused on how young people think and act on socialmedia in relation to constructions of gender and normality. The analysis is based on fourgroup interviews with 13-year old boys and girls. The theoretical approach is based partly onsocial constructionism where discourses and ideas of normality are identified and analyzed.Erving Goffman's theory of social interaction was central to illustrate how young peoplepresents themselves based on the prevailing discourses. It is clear that they adjust theirrepresentations of themselves depending on the context.
