2020 Uppsatser om Frequency altered feedback - Sida 52 av 135

Testprogram till hårdvara på en viktindikator

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.

Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014

As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.

Utmaningar i den psykosociala arbetsmiljön - en studie av HR-arbete i ideell sektor

The purpose of this study is to conduce to the understanding of what challenges the HRdepartmentfaces in the work with the psychosocial work environment in nonprofit organizationsin Sweden. A particular focus in the study is on how the certain features of the nonprofit sectoraffect and tend to contribute to these challenges. In both Swedish and International research thereappears to be a lack of studies that deal with the psychosocial work environment in the nonprofitsector, which is one of the main reasons for this study. International research show, among otherthings, that employees in this sector have a higher degree of work satisfaction than in othersectors.

Probiotika som prevention mot urogenitala sjukdomar

About 10 % of the adult women population in Sweden are treated annually for urinary tract infections. The increasing bacterial resistance towards antibiotics is classified by WHO (World Health Organization) and ECDC (European Centre for Disease Prevention and Control) as one of the greatest treats for human health in a global perspective. To find alternatives scientists are studying the possibility to use probiotics to reduce the frequency of recurring urinary tract infections. This literature study examines five randomized double blinded placebo controlled studies where different strains of Lactobacillus have been used as a prophylactic to women suffering from recurrent urinary tract infections and bacterial vaginosis. Overall the studies do not display enough promising results to recommend the use of probiotics as a prophylax or cure..

Nyhetsförmedling genom en webblogg? : studie av webbloggar som kommunikativ kanal

Webbloggens aktualisering i medielandskapet har inspirerat oss till denna uppsats vilken behandlar detta nya fenomen. Främst riktas uppsatsens fokus mot att studera hur webbloggens potential kan användas som komplement till andra kanaler som används för nyhetsförmedling och debatt i det offentliga rummet. Vidare önskar vi finna svaret på om någon demokratisk funktion för webbloggen existerar? Kan webbloggen som kommunikationskanal bidra till att skapa en deliberativ demokrati genom att inbjuda till dialog i offentligheten. Kan den information som publiceras komplettera den traditionella nyhetsförmedlingen?Till grund ligger en kvalitativ studie som bygger på fältstudier på sex bloggande journalister och deras webbloggar.

"Jag hävdar att det här har funnits jämt" : Formativ bedömning på mellanstadiet

The porpuse of this paper is to find out how three teachers working in years four to six in a Swedish school say they use formative assessment and how they use it in educational practice, and if there is a difference in the use of formative assessment between year four, five and six. Formative assessment is the kind of assessment that aims to enhance the student?s learning, as opposed to summative assessment wich is intended only to summarize student?s accomplishments. To answer the purpose, I conducted qualitative interviews with the teachers, and observations in each of the teachers? classrooms.

Övergödning av Mälaren : Betydelsen av antalet beviljade dispenser av stallgödselspridning vid Sagån

Eutrophication was recognized in the early 1900's and results in severe algal blooms, increased biomass production and eventually leads to an altered ecosystem. In Mälardalen we find the most eutrophic lakes. Most of the applied phosphorus and nitrogen into seas and oceans comes from agriculture, and the nutrients losses are affected by local weather conditions and soil type. Guidelines for storage and distribution of manure were introduced in the 80s, and the rules were strengthened January 1, 2010. Localities and previous county administrations can whether there are special reasons, grant an exemption for manure application during winter-periods despite the current ban.In this essay I have examined how many exemptions of manure application that has been granted at the Sagån river, and what implications it has for the eutrophication of Lake Mälaren.

Värmestyrning I Handske

This rapport is result of a project. The purpose of which was to design a circuit that is used in a heat glove. The heat glove is the technical aid which provides heat inside a glove.It is specially suited for old people who have problems with cold hands because of decreased blood circulation.There already was an old circuit in the glove that gives a constant current which develops heat from battery to glove through a circuit. The temperature is between 32 and 34 degrees.The problem with the existing circuit was to regulate the temperature. There is only on/off switch and there is no way to adjust desirable value of the temperature.In order to solve the problem the old circuit was investigated.

Kvinnor i toppen : En studie av kvinnligt delägarskap i advokatbyråer och personalmotivation

Denna uppsats undersöker problemet med att få kvinnor blir delägare på advokatbyråer. Herzbergs tvåfaktorteori används för att undersöka om skillnader i personalmotivation mellan män och kvinnor är en bidragande faktor till detta problem. Efter genomförda intervjuer med ledningen och besvarade enkäter av anställda på advokatbyråer kan det konstateras att det finns avgörande skillnader i faktorer som motiverar män respektive kvinnor i arbetet. Hackmans och Oldhams implementeringsplan för arbetsberikning utgör grunden för de lösningsförslag som presenteras. Sammantaget innehåller lösningsförslagen utökat arbetande i team, tidigare klientkontakt, ökad transparens, tidigare ledarskapsutbildning, mer feedback samt alternativa karriärvägar..

Telekrig mot bandspridningsteknik

I denna uppsats betraktas två olika bandspridningstekniker och vilken påverkan de har på telekrigsförmågan. Uppsatsen svarar på frågan:Vilka möjligheter finns att bedriva signalspaning och störning mot radiokommunikation som använder bandspridningsteknikerna frekvenshopp eller direktsekvens?Inledningsvis beskrivs en modell för telekrig mot radiokommunikation, ?telekrigcykeln?. Därefter beskrivs principer för ett radiosystem samt de två bandspridningsteknikerna frekvenshopp och direktsekvens. Slutligen analyseras bandspridningsteknikernas påverkan med hjälp av telekrigcykeln och resultaten diskuteras.Uppsatsen kommer fram till att båda signalerna går att spana mot, direktsekvens innebär större svårigheter för signalspaningen än frekvenshopp.
