Arduinobaserad hundpejl

Larsson, Oskar January 2017 (has links)
En hundpejl är idag något absolut nödvändigt vid löshundsjakt. Anledningen är att jägaren måste veta vart hunden är och helst också vad som sker. Idag när trafiken ökar allt mer är det av vikt att i tid kunna avgöra om hunden är på väg mot en trafikerad väg. Om hunden blir still har man möjlighet att i tid avgöra om den fastnat eller har gått i vatten och har möjlighet att hinna fram i tid för att hjälpa. Och då hundpejlar ofta kostar mer än 2000 kronor så finns det ett önskemål om att ta fram billigare varianter av hundpejlar. Målet i detta projekt är därför att konstruera, montera och programmera en pejl av Arduino UNO och Adafruit FONA 808 som uppfyller de krav, såsom en batteritid på minst 8 timmar och ett precisionsfel på max 5 meter, som en jägare ställer på en pejl som samtidigt är billigare en kommersiell produkt med liknande prestanda. Tillgångavägssättet var sådant att först studerades relevant litteratur såsom Adafruits produktbeskrivning och testkod, sedan testades de olika enskilt funktionerna, skicka, ta bort och läsa SMS samt hämta GPS-koordinater. När det var klart att funktionerna fungerade programmerades en kod som erhåller de egenskaper som en användare önskar sig.  Därefter utvärderades pejlen för att se om den uppfyller de ställda kraven. Det som testades var pejlens vikt, batteritid och positionsnoggrannhet. Vikten mättes på en köksvåg, batteritiden mättes genom att testa batteriladdningen en gång i timmen över tre timmar och positionsnoggrannheten mättes på sådant sätt att pejlens koordinater jämfördes med resultatet från Google Maps och Eniro. Det visade sig att pejlen inte helt uppfyller alla krav, då positionsnoggrannheten inte direkt uppfyller de kraven som är ställda. Dock är enheten fortfarande användningsbar för spårning då den ger en tillräcklig generell area för att kunna hitta en hund på. Pejlen kan även användas i andra syften, till exempel placera den i en bil utifall stöld. Den ger även en bas att vidareutveckla en hundpejl ifrån till exempel skicka ljud till en telefon vilket även intresserar jägare. / A dog tracker is something that is essential when hunting with a dog. The reason is because the hunter needs to know where the dog is always, while preferably as well knowing what happens with the dog. Today, when the traffic is increasing and more, it is of importance to be able to determine whether the dog is heading for a busy road. The tracker also gives the hunter the possibility to rescue the dog if it gets stuck or fall in water. Dog trackers are of importance to the hunter, but they are also expensive, most costs more than 2000 SEK/230 USD, so there is a desire for a cheaper dog tracker that still fulfil the demands that hunters or dog owners require. The goal of this project is to design, build and program a dog tracker from Arduino UNO and Adafruit FONA 808, that meets the requirements stated by a user and at the same time are cheaper than the commercial equivalents. The method used are such that first relevant documents, such as Adafruit product description and testcode, are studied to gain an understanding of the units used. The units were then tested by the testcode to ensure that all parts are working correctly, this was done by testing read, delete and send SMS and get GPS-coordinates. When it was sure that all parts worked correctly a code was programmed that fulfilled all the requirements requested by a user. Then the finished dog tracker was evaluated to ensure that it fulfilled the requirements. Weight, battery time and positioning accuracy was tested, where weight was tested by a kitchen scale, battery time was tested by measuring the loss of charge once an hour over a period of three hours. From what was measured in those three hours a battery time was calculated by extrapolating loss of battery power/hour. The positioning accuracy was measured by using the dog trackers coordinates and comparing them to Google Maps and Eniro coordinates. The conclusion of the project is that the dog tracker didn’t fulfil all the requirements, its positioning accuracy didn’t reach the requirement of max 5-meter error. Though the dog tracker is still usable for tracking because it still gives a good enough positioning for finding a dog. The dog tracker can also be used for other purposes such as placing in a car to track it in event of a theft. The dog tracker also acts as a base for future developments, like using it to send sound which is also of interest for a hunter.

De la relance multicanal du client fidèle à la performance commerciale des enseignes de ditribution spécialisées. / From the multi-channel relaunching of the loyal customer to the commercial performance of specialized retails.

Méral, Hélène 14 December 2018 (has links)
Dans un contexte de développement des stratégies marketing multi-canal lié principalement à l’évolution constante de l’outil Internet et des nouvelles technologies de diffusion (Dupuis, Prunet, 2001 ; Dabholkar, 1996), il convient de mieux comprendre les effets de ces stratégies sur la performance commerciale de l’entreprise via le processus de fidélisation client. Ainsi, ce projet de recherche propose d’investiguer, à travers diverses études quantitatives l’effet les relances multi-canal sur la fidélité envers les enseignes à travers une opération "chèque fidélité". l'étude permettra de construire un modèle de référence dont la duplicité sera vérifiée afin d'être exploité sur plusieurs secteurs d'activité commerciale. / In a context of development of the multi-channel marketing strategies bound mainly to the constant evolution of the Internet tools and the new technologies of distribution (Dupuis, Prunet, on 2001; Dabholkar, on 1996), it is advisable to understand the effects of these strategies on the companies' commercial performance through the process of customer loyalty development. So, this research project suggests investigating, through diverse quantitative studies, the effect the multi-channel relaunchings on loyalty programs to signs through an operation "check". The study will allow to build a benchmark model which the duplicity will be verified to be exploited on several business sectors.

Localizing global trends in sms texting language among students in Ghana and Tanzania

Dzahene-Quarshie, Josephine 10 March 2017 (has links)
The main motivation for the development of various strategies to represent written text in a concise way among mobile phone users all over the world is the need to communicate full messages in abridged forms in order to save time, energy and money. These alternative forms of words and phrases are especially employed by the youth. In this paper, the innovative adaptation of global SMS texting trends in the form of intricate abbreviation and contraction of words and phrases in Kiswahili in Tanzania is examined and compared with trends in SMS texting language in English in Ghana. Using empirical data made up of SMS texts from students of the University of Dar es Salaam and University of Ghana, localized as well as convergent and divergent trends and the socio-pragmatic motivations of the phenomena are analysed and discussed.

Emojier – Ett lingua franca för den digitala tidsåldern : men hur användbart är det egentligen? / Emojis – a lingua franca of the digital era : But in reality, how useful is it?

Eerola, Isabelle, Wahlén, Felicia January 2019 (has links)
Emojier har kommit att bli en stor del i hur vi interagerar med varandra, både online och offline och dagligen innehåller närmare 40 procent av alla sms i västvärlden en eller flera emojier. 2009 valde Unicode Consortium att implementera emojier i sin standard och därefter valde Apple som första kommersiella företag att lägga till emojier i sitt tangentbord. Tidigare undersökningar har delade meningar om huruvida det är en skillnad i användandet av emojier mellan yngre och äldre åldersgrupper. Forskningen har främst fokuserat på användningen av emojier online i sociala kanaler, därav finns det bristfällig forskning om hur emojier upplevs i en interaktion som sker offline. Syftet med denna studie är att undersöka hur emojier upplevs offline via sms i iOS gränssnitt av emojier, detta görs genom en jämförelse mellan två åldersgrupper: 20–30 år samt 50–60 år. Studien har också syftet att undersöka möjliga förbättringar till iOS gränssnitt av emojier för att främja god användbarhet. Studiens kvalitativa ansats innebär ostrukturerade observationer och semi-strukturerade intervjuer. Resultaten visar på både likheter och skillnader mellan åldersgrupperna om hur de upplever emojier i en interaktion som sker via sms. Det framkommer också brister i användningen av gränssnittet som motverkar en god användbarhet där informanterna får ge förslag till en förbättring av gränssnittet. / Emojis have become a major part of how we interact with each other, online as well as offline and almost 40 percent of all text messages in the Western world contains one or more emojis. In 2009, the Unicode Consortium chose to implement emojis in their standard which entailed that Apple became the first commercial company to add emojis to their keyboard. Previous studies have different opinions on whether or not there is a difference in the use of emojis between younger and older various age-groups. Former studies have mainly focused on the use of emojis in social channels online, however, there is little research on how emojis are experienced in an offline interaction. The aim of this study is to investigate how emojis are experienced offline through text messages in iOS interface of emojis, this is done by comparing two age-groups: informants between the ages of 20-30 and 50-60. Moreover, this study aims to explore the possibilities of improvements of the iOS interface of emojis in order to further improve user experience. The qualitative approach of the study involves unstructured observations and semistructured interviews. The results show both similarities and differences between the age-groups on how they experience emojis when interacting through text messages. It also appears shortcomings in the use of the interface which undermine good usability.

Giusti, Maurício Lobo 20 October 2014 (has links)
Made available in DSpace on 2016-03-22T17:27:36Z (GMT). No. of bitstreams: 1 mauricio lobo giusti.pdf: 744375 bytes, checksum: 3b95bba23b095fb11f1409e04f576b46 (MD5) Previous issue date: 2014-10-20 / Objectives: Characterize the female futsal high-level athletes em Brazil, check the characteristics of the athletes invited to the Brazilian national team in 2013, as well as identify the motivational profile and evaluate the factors associated with motivation for the Sport among athletes. Method: Transversal descriptive study, having Brazilian futsal athletes as target audience, participants of the 2013 Feminine Futsal League. It was applied a questionnaire created by the researchers and the profile of motivation was evaluated through the Sport Motivation Scale (SMS). Results: The majorities of athletes are adults, of socio-economic classification B, are studying with integral funding, started playing at the streets or school, with less than 9 years old. Also, they would like to dedicate more time to futsal and the majority is paid to play. Being called-up is associated with being adult, having finished high school or attending post-graduation, receiving integral funding and being invited, indicated or hired from other team by their current team. The average score of the athletes for intrinsic motivation (IM) were higher than the score of extrinsic motivation (EM). The average of demotivation dimensions presented the lowest values. The athletes that were studying present higher IM. The athletes with 10 years or more in futsal were the most demotivated. Conclusion: This research sought to describe the profile of athletes that dispute the most important futsal national championship, besides describing the characteristics of the athletes that were called up for the Brazilian national team. Starting from these findings, it was notices an important encouragement to education continued between the athletes and also a high score of intrinsic motivation that seems to be connected with studying. The demotivational scores were low, however, the increase of years of practice may lead to higher scores of demotivation in the sport / Objetivos: Caracterizar as atletas de futsal feminino de alto rendimento no Brasil, verificar as características das atletas convocadas para a seleção brasileira em 2013, bem como, identificar o perfil motivacional e avaliar os fatores associados à motivação para o esporte entre as atletas. Método: Estudo descritivo transversal, tendo como população alvo as atletas brasileiras de futsal, participantes da Liga Futsal Feminina 2013. Foi aplicado um questionário estruturado criado pelos pesquisadores e o perfil da motivação foi avaliado através da Escala de Motivação no Esporte (SMS). Resultados: A maioria das atletas é adulta, de classificação econômica B, está estudando com financiamento integral, começou a jogar na rua ou na escola, com menos de 9 anos. Também gostariam de dedicar mais tempo ao futsal e a grande maioria é remunerada para jogar. Ser convocada esteve associado a ser adulta, ter concluído o ensino superior ou estar cursando pós-graduação, receber financiamento integral dos estudos e ter sido convidada, indicada ou contratada de outra equipe para sua equipe atual. Os escores médios das atletas para motivação intrínseca (MI) foram maiores que os escores de motivação extrínseca (ME). A média da dimensão desmotivação apresentou os menores valores. As atletas que estavam estudando apresentaram maior MI. As atletas com dez anos ou mais na prática do futsal estavam mais desmotivadas. Conclusão: Este estudo buscou caracterizar e descrever o perfil motivacional das atletas que disputaram o campeonato nacional mais importante da modalidade, além de descrever as características das atletas convocadas para a Seleção Brasileira. A partir destes achados observou-se um importante incentivo a educação continuada entre as atletas e também um alto escore de motivação intrínseca que parece estar relacionada ao estudo. Os escores de desmotivação foram baixos, no entanto, o aumento dos anos de prática parece levar a maiores escores de desmotivação para o esporte

SMS i TV : ett sätt att skapa interaktion i TV?

Cedergren, Daniel, Terning, Gustaf January 2002 (has links)
<p>The purpose with this essay is to examine the phenomenon SMS in TV. Partly by identify the communication process behind the phenomenon and partly by describing it in a editorial and technical point of view. We have analysed the communication process regarding scientific theories in communication, interaction and convergence. With a qualitive approach we have fulfilled four interviews and two small ethnographical field observations. Objects for the interviews and observations have been two Swedish produced debate-programs, broadcasted in TV; Diskus in TV4 and Debatt in SVT2. Our conclusions shows that the phenomenon SMS in TV provides the traditional one-way communicative medium TV a new opportunity to create a feedback-channel between the TV-viewer and the TV-producer. The main purpose with SMS in TV from a TV-producers point of view is to let the TV-viewer have the possibility to send a SMS-message with his or her thoughts or questions to the TV-producer and by that affect the TV-program. Our conclusions also describes how the phenomenon is used in a editorial way and how it’s produced and used in a technical point of view. Further discussions are made regarding problems connected to the phenomenon and it’s future possibilities. </p> / <p>Uppsatsens syfte är att undersöka fenomenet SMS i TV. Dels för att identifiera fenomenets kommunikationsprocess och dels för att åskådliggöra fenomenet redaktionellt och tekniskt sett. För att analysera fenomenets kommunikationsprocess har vi valt att utgå från kommunikations-, interaktions- och konvergensteorier. Med en kvalitativ ansats har vi genomfört fyra intervjuer samt två mindre fältobservationer med etnografisk ansats. Utgångspunkten för dessa har varit de svenskproducerade TV-sända debattprogrammen Diskus i TV4 och Debatt i SVT2. Slutsatserna visar att fenomenet SMS i TV ger det traditionellt envägskommunikativa mediet TV en möjlighet till återkoppling mellan TV-tittaren och TV-producenten. Syftet med SMS i TV är att från TV-producentens sida samverka med TV-tittaren genom att låta denne skicka ett SMS-meddelande med sin åsikt eller fråga i för att påverka innehållet i det aktuella TV-programmet. Slutsatserna beskriver även hur fenomenet används redaktionellt och hur det produceras och fungerar tekniskt sett. Vidare diskuteras problematiken med SMS i TV samt fenomenets möjligheter i framtiden. </p>

Övergivande av fartyg i isfarvatten : En kvalitativ studie över svenska rederiers beredskap inför nödsituationer i isfarvatten.

Granlund, Andreas, Torvaldsson, Jonas January 2011 (has links)
Trots att isen lagt sig på Bottenhavet avstannar inte handeln med de norrländska hamnarna. Många av de fartyg som anlöper dessa hamnar har som primär överlevnadsfarkost en frifallslivbåt, en typ av livbåt som av experter har blivit utdömda som värdelösa i samband med is. Även fartygens sekundära överlevnadssystem, som består av uppblåsbara flottar, har blivit kritiserat. Syftet med detta arbete var att undersöka vad svenska rederier med fartyg som bär denna typ av livbåt har för beredskap inför en eventuell nödsituation i isen.   Undersökningen har grundats på en kvalitativ intervjustudie med representanter från tre svenska rederier som bedriver vintersjöfart. Studien har visat på stora skillnader mellan de olika rederierna gällande rutiner för att operera i is. Inget av rederierna som intervjuats har haft en speciell plan för övergivandet av fartyg i isförhållanden, trots att de har en säkerhetsorganisation som blivit godkänd av den svenska Transportstyrelsen. / Even though the ice has formed on the Gulf of Bothnia the trade with the northern ports of Sweden and Finland does not cease. Many of the ships calling these ports have their primary survival craft in form the of a freefall lifeboat, a survival craft that experts have condemned as useless in ice. Even the ship's secondary survival system consisting of inflatable rafts has been criticized. The purpose of this study was to examine what kind of plan Swedish shipping companies, who operate vessels that carry this type of lifeboat, have to deal with a possible emergency situation in the ice. The study was based on qualitative interviews with representatives from three Swedish shipping companies operating in winter conditions. The study revealed great differences between the various companies in routine procedures when operating in ice. None of the interviewed companies had a special plan for the abandonment of ships in ice conditions, although they have a safety organization approved by the Swedish Transport Agency.
