Link QualityControl (LQC) i GPRS/EGPRS
This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.
Designteori i praktiken : En undersökande fallstudie om hur designteori manifesterar sig i praktiken
New technologies and new consumer behaviors are having a large impact on mediacompanies. The biggest change is in the behavior of the younger demographic whereold platforms like television are abandoned for new online platforms. In this newworld, media companies and organizations need new tools and business models tostay competitive. One such tool is Design Thinking, a term used to describe a cognitivedesign-specific set of activities used during a design process. It has been popularizedin commercial areas and there the term is used to describe an applicable workflowused to promote the skills required to use Design Thinking.
Beslutsfattande och uppmärksamhet : Heuristikers påverkan på kognitiva resurser inom konsumentpsykologi
Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.
Subjektiva och objektiva jämförelser mellan två benledningshållare, Softband och Adjoin
Background: Bone anchored hearing system is a surgically implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..
Att må sämre för att må bättre ? om könskorrigering, utredning och upplevelsen av psykisk hälsa
Med en kvalitativ ansats baserad på en semistrukturerad critical incidents-intervju och Interperative phenomenological analysis undersöktes en frågeställning om transexuellas egna upplevelser av hur deras välmående och psykiska hälsa påverkas av att de genomför utredning som syftar till en könskorrigering. Informanterna, 5 stycken totalt, varav 4 var Male-to-female och 1 Female-to-male, rapporterar både positiv och negativ påverkan från utredningstiden. Studien sammanställer de sammanhang som informanterna rapporterar har haft störst inverkan på deras välmående och psykiska hälsa, till exempel väntan, real life-test och bemötande. Ur intervjuerna framträder ett komplicerat förhållande mellan utredare och behandlare kontra den som utreds, där den professionelles agerande kan få stor betydelse för hur den utredde uppfattar att utredningen påverkar deras psykiska hälsa och välmående..
Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire
Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.
Resebloggens relevans - innehållet som fångar läsaren
This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.
Sjuksköterskans identifiering av smärta hos äldre personer med demenssjukdom : En litteraturstudie
Syfte: Att utifrån litteratur beskriva hur sjuksköterskor kan identifiera smärta hos äldre personer med demenssjukdom, samt att undersöka vilka mätinstrument som finns att tillgå för att beskriva smärta. Metod: Litteraturstudien var av deskriptiv design. Litteratursökningen gjordes i databaserna PubMed och Cinahl. Resultat: Resultatet baserades på 14 vetenskapliga artiklar som visar att det finns många uttryck för smärta som sjuksköterskan kan använda sig av för att identifiera smärta hos äldre personer med demenssjukdom. Resultatet visade att det är mycket svårare att identifiera smärta vid omvårdnad av äldre demenssjuka, då de inte kan kommunicera som kognitivt intakta personer.
Kan företag tvingas till tillväxt?
The purpose with this disertation is to find if there are selected factors which can force companies to grow. We have chosen five factors which we think can force the companies; market, strategy, profitability, demographic and institutional factors. We want to examine if there are differences between small and larger companies, and if there are differences between the lines of business.The intention to growth is also influenced by different factors. The organization and the board have an effect on the development. There are also factors that can obstruct the growth, for example control.
Förbränningslära för bubblandefluidbädd
Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Utvärdering av regnmätning och droppstorleksfördelning från en distrometer
Nederbördsmätning är viktigt inom många områden och en relativt ny teknik är enoptisk distrometer som med hjälp av laserteknik mäter nederbördspartiklarnasdroppstorlek och fallhastighet. Syftet med detta arbete var att undersöka hur välThies distrometer stämmer överens med nederbördsmätning från ett vippkärl ochmanuella mätningar från institutionen för geovetenskaper vid Uppsala universitet.Institutionen för geovetenskaper överväger att gå över till denna teknik och därmedbehövdes distrometern utvärderas för olika faktorer som kan påverka instrumentet.Vid jämförelse mellan instrumenten visade det sig att distrometern totalt sett samladein mer nederbörd än de andra mätarna. Det är svårt att avgöra vad skillnaden mellaninstrumenten kan bero på men felkällor så som avdunstning och vätning hos vippkärletoch manuella mätningar kan ge mindre nederbörd. En annan orsak kan varafelkalibrering av datan från distrometern. Inga samband hittades för vindhastighet,vindriktning och typ av nederbörd mellan de tre instrumenten.En vidare undersökning gjordes för droppstorleksfördelningen för att ge exempelpå fördelar med en distrometer.
Tillämpning av hedonisk prissättning på bostadsrätter : En analys av bostadsmarknaden i Uppsala
Syftet med denna studie är att analysera vad det är som påverkar bostadspriserna på Uppsalas bostadsmarknad. Det är spekulanternas önskemål och krav, det vill säga deras betalningsvilja som påverkar priset. Det kan skilja sig mellan olika spekulanter men för det mesta ses ett tydligt mönster. Spekulanter värdesätter t.ex. områden som ligger nära centrum.
Strategisk kommunikation inom fastighetsbranschen : En kvalitativ undersökning om skillnader och likheter i kommunikationen mellan ett kommunalt och privat bolag
The aim of this study is to find and highlight the differences and similarities in the strategic communication in two real estate businesses with different proprietaries. In order to achieve the purpose, theories and previous research on public relations, strategic communication, mediatization, framing and new public management has been used. The study was conducted through interviews with two different organizations, Lerstenen who is based in Umeå, and Övikshem who is based in Örnsköldsvik. The analysis and results showed that the key difference between the firms was the spontaneity that influenced the private one, in contrast to the public firm that relied on solid structures to manage their communication. The results also showed that differences in basis conditions both allowed and hindered the possibilities with the communicative efforts that the two firms could do..
Chefskap, administration och IT - Hur går det ihop? : En kvalitativ studie av hur enhetschefer inom kommunal verksamhet upplever IT-system
The increasing administration in IT-systems is the target of much debate today. It is viewed as taking time from what is considered to be managers? real tasks as well as resulting in an ineffective and stressful work environment. This view of IT-systems as problematic and time consuming can also been found among unit managers in a municipality in the north of Sweden. To be able to understand why IT-systems are perceived in this way this study?s aim has been to find what leads to this view.
Människan - en gruppvarelse : en kvalitativ studie om grupperingars och status betydelse för elever i årskurs 9
In this study, five qualitative interviews were conducted, four of those with pupils and one with a teacher, in grade 9. Humans - a gregarious creature written in the context of status and hierarchy, aims to study how these students in grade 9 are grouped and how you look at each other in and between these groups and also in terms of status between and within the group. Using the concepts of identity, adaption, exclusion and the meaning of emotions with the chosen theoretical concepts by Goffman and, Elias and Scotson the purpose of this study has been answered. The results showed that the students were quite flexible between the groups in their class; most of them were part of a small group that consisted of their ?close? friends.
