Résumé :

Agrarian pruning and plantation removal (APPR) is a common residue from pomo-technical maintenance of orchards, vineyards, and olive groves, frequently overlooked by the energy sector. This paper sheds new light on the socio-economic role of APPR as solid biofuel. The paper suggests business models that could both alleviate energy poverty in rural areas and increase the competitiveness of perennial crop (fruits, olives, vine) production. The effects of mobilizing APPR potential via business models are estimated at the micro (households’ income) and macro (number of households affected, size of the investment, tax effect, CO2eq savings) levels in the Croatian setting. Contrary to classical energy planning, the paper provides an approach that fosters local use of bioenergy by linking rural development with renewable energy end-use. The approach linked pruning energy potential with 47% of Croatian rural households which allows creating an evidence-based policy for rural development utilizing APPR as a sustainable solid biofuel. The most attractive business model for Croatian rural areas is utilization of APPR as a solid biofuel. It could be used as an energy poverty alleviation measure, allowing savings per heating season equivalent to 5%–11% of the average disposable income per household. Net APPR influence at VAT tax is estimated at 5.5 million euro·y−1. The paper proves that using average values for APPR in energy planning could be misleading.

Résumé :

In patients with Alzheimer’s disease (AD), synaptic plasticity seems to be involved in cognitive improvement induced by cognitive training. The platelet amyloid precursor protein (APP) ratio (APPr), i.e., the ratio between two APP isoforms, may be a useful peripheral biomarker to investigate synaptic plasticity pathways. This study evaluates the changes in neuropsychological/cognitive performance and APPr induced by cognitive training in AD patients participating in the “My Mind Project”. Neuropsychological/cognitive variables and APPr were evaluated in the trained group (n = 28) before a two-month experimental protocol, immediately after its termination at follow-up 1 (FU1), after 6 months at follow-up 2 (FU2), and after 24 months at follow-up 3 (FU3). The control group (n = 31) received general psychoeducational training for two months. Some memory and attention parameters were significantly improved in trained vs. control patients at FU1 and FU2 compared to baseline (Δ values). At FU3, APPr and Mini Mental State Examination (MMSE) scores decreased in trained patients. Δ APPr correlated significantly with the Δ scores of (i) MMSE at FU1, (ii) the prose memory test at FU2, and (iii) Instrumental Activities of Daily Living (IADL), the semantic word fluency test, Clinical Dementia Rating (CDR), and the attentive matrices test at FU3. Our data demonstrate that the platelet APPr correlates with key clinical variables, thereby proving that it may be a reliable biomarker of brain function in AD patients.

Résumé :

Reconfigurable antenna systems have gained much attention for potential use in the next generation wireless systems. However, conventional direction-of-arrival (DoA) estimation algorithms for antenna arrays cannot be used directly in reconfigurable antennas due to different design of the antennas. In this paper, we present an adjacent pattern power ratio (APPR) algorithm for two-port composite right/left-handed (CRLH) reconfigurable leaky-wave antennas (LWAs). Additionally, we compare the performances of the APPR algorithm and LWA-based MUSIC algorithms. We study how the computational complexity and the performance of the algorithms depend on number of selected radiation patterns. In addition, we evaluate the performance of the APPR and MUSIC algorithms with numerical simulations as well as with real world indoor measurements having both line-of-sight and non-line-of-sight components. Our performance evaluations show that the DoA estimates are in a considerably good agreement with the real DoAs, especially with the APPR algorithm. In summary, the APPR and MUSIC algorithms for DoA estimation along with the planar and compact LWA layout can be a valuable solution to enhance the performance of the wireless communication in the next generation systems.

Résumé :

Background & Purpose This article focuses on the current educational reform movement in New York State resulting from the state's receipt of $700 million in Race to the Top (RTTT) money. Specifically, the article will focus on one aspect of the RTTT requirement, which requires that school districts develop teacher accountability systems that are based in part on test data, i.e., the Annual Professional Performance Review (APPR). We will provide an account of how the New York State Education Department's implementation of RTTT has changed the role of educators, eroded autonomy in publicly controlled schools, promoted a culture of mistrust, diverted funds from the classroom to meet governmental directives, and paved the way for corporate vendors to profit from taxpayer money. Finally, we will examine whether the APPR policy developed to hold teachers accountable using an objective metric is a reliable and valid one. Research Design We examine the APPR legislation passed by both the legislative and executive bodies of New York State by focusing on field guidance documents and legislation released by the State Education Department (SED) as well as memos we received from SED. We also review how school districts have decided to implement APPR in their local environment. Finally, articles appearing in the press about the APPR have also been surveyed to ascertain key themes about the question whether teacher effectiveness can be objectively measured by those standards set forth by the SED. Conclusions The APPR policy as it is currently implemented is an unreliable tool in measuring teacher performance. Its subjectivity and inconsistent implementation calls into question the core purpose of this reform, i.e. to rid schools of poor performing teachers, while identifying those that are excellent. The implementation of RTTT and APPR has deteriorated the quality of public education in New York State by creating confusion through untested policies, creating a culture of distrust, diverting money from the classroom to for profit vendors, and developing a pedagogical methodology of teaching to the test.

We explore the semantics and typology of functional morphemes encoding apprehensional, i.e. negative prospective, meanings through a detailed case study of the adjunct uses of =sa'ne 'APPR' in A'ingae (or Cofán, ISO 639-3: con, an Amazonian isolate). We provide one of the first formal accounts of apprehension: In a structure [p [q=sa'ne]], =sa'ne 'APPR' encodes a modal semantics where the goal worlds of the actor responsible for p avoid a salient situation r=>q. Finally, we reveal two inherent asymmetries among apprehensional functions (precautioning asymmetry and timitive asymmetry), thus making substantial predictions with regards to typological patterns in apprehensional morphology.

Résumé :

Background. Low-Risk Human Papillomavirus (LR-HPV) genotypes 6 and 11 cause genital warts. This study investigated the association of LR-HPV infection with male circumcision (MC).Methods. We used data from the South African MC trial conducted among young men. Urethral swabs, collected among intervention (circumcised) and control (uncircumcised) groups, were analyzed using HPV linear array. Adjusted LR-HPV prevalence rate ratio (aPPR) and Poisson mean ratio (aPMR) of number of LR-HPV genotypes were estimated using log-Poisson regression, controlling for background characteristics, sexual behaviour, and HIV and HSV-2 statuses.Results. Compared to controls, LR-HPV prevalence and mean number of genotypes were significantly lower among the intervention group ((8.5% versus 15.8%; aPRR: 0.54,P<.001) and (0.33 versus 0.18; aPMR: 0.54,P<.001), resp.). Mean number of LR-HPV genotypes increased with number of lifetime sexual partners and decreased with education level and consistent condom use.Conclusions. This study shows a reduction in LR-HPV infection among circumcised men.

Résumé :

For a long time, the equivalent ionospheric slab thickness τ has remained in the shadow of ionospheric main parameters: the maximum density, NmF2 (or the critical frequency, foF2), and the total electron content. Empirical global models have been developed for these two parameters. Recently, several global models of τ have appeared concurrently. This paper compares τ of the Neustrelitz equivalent slab thickness model (NSTM), with τ(IRI-Plas) of the IRI-Plas model, and τ(Appr) of the approximation model, constructed along the 30° E meridian using data from several ionosondes. The choice of the model of the best conformity with observational data was made, which was used to study the effects of space weather during several magnetic storms in March 2012. The effects included: (1) a transition from negative disturbances at high latitudes to positive ones at low latitudes, (2) the super-fountain effect, which had been revealed and explained in previous papers, (3) a deepening of the main ionospheric trough. The efficiency of using τ(Appr) and τ(IRI-Plas) models for studying the effects of space weather has been confirmed. The advantage of the τ(Appr) model is its closeness to real data. The advantage of the τ(IRI-Plas) model is the ability to determine foF2 without ionosondes. The efficiency of the NSTM model is insufficient for a role of a global τ model due to the accuracy decreasing with the increasing latitude.

Résumé :

Abstract The focus of this thesis is to study direction of arrival (DoA) estimation algorithms for reconfigurable leaky-wave antennas and advanced antenna arrays. Directional antennas can greatly improve the spectrum reuse, interference avoidance, and object and people localization. DoA estimation algorithms have also been shown to be useful for applications such as positioning for user tracking and location-based services in wireless local area networks (WLANs). The main goal is to develop novel DoA estimation algorithms for both advanced antenna arrays and composite right/left-handed (CRLH) leaky-wave antennas (LWAs). The thesis introduces novel modifications to existing DoA estimation algorithms and shows how these can be modified for real-time DoA estimation using both antenna types. Three modified DoA estimation algorithms for CRLH-LWAs are presented: 1) modified multiple signal classification (MUSIC), 2) power pattern cross-correlation (PPCC), and 3) adjacent power pattern ratio (APPR). Additionally, the APPR algorithm is also applied to advanced antenna arrays. The thesis also presents improvements to the modified MUSIC and APPR algorithms. The complexity of the algorithms is reduced by selecting a smaller number of received signals from different directions. The results show that the selection of the radiation patterns is very important and that the proposed algorithms can successfully estimate the DoA, even in a real-world environment. Based on the results, this thesis provides a good starting point for future research of DoA estimation algorithms to enhance the performance of future-generation wireless networks and the accuracy of localization
Tiivistelmä Tässä väitöskirjassa tutkitaan suunnanestimointialgoritmeja uudelleen konfiguroituville vuotoaaltoantenneille (LWA, leaky wave antenna) ja kehittyneille antenniryhmille. Suuntaavilla antenneilla voidaan parantaa huomattavasti spektrin uudelleen käyttöä ja esineiden ja ihmisten sijaintipaikannusta sekä pienentää häiriöitä. Suunnanestimointialgoritmit ovat myös osoittautuneet hyödylliseksi esimerkiksi seuranta- ja sijaintipaikannuspalvelusovelluksille langattomissa lähiverkoissa. Työn päätavoite on kehittää uusia suunnanestimointialgoritmeja sekä kehittyneille antenniryhmille että vuotoaaltoantenneille (composite right/left-handed (CRLH) LWA). Työssä osoitetaan, miten olemassa olevia suunnanestimointialgoritmeja voidaan muokata uudella tavalla, jotta ne soveltuisivat molemmille antennityypeille reaaliaikaiseen suunnanestimointiin. Vuotoaaltoantennille on kehitetty kolme erilaista suunnanestimointialgoritmia: 1) muunneltu MUSIC- (multiple signal classification), 2) säteilykyvioiden tehojen ristikorrelaatio- (PPCC, power pattern cross correlation) ja 3) vierekkäisten säteilykuvioiden tehosuhdealgoritmi (APPR, adjacent power pattern ratio). APPR-algoritmia on myös käytetty kehittyneelle antenniryhmälle. Työssä esitetään myös parannuksia muunnelluille MUSIC- ja APPR-algoritmeille. Algoritmien kompleksisuutta voidaan pienentää valitsemalla vähemmän vastaanotettuja signaaleja. Tulokset osoittavat, että signaalien valinta on hyvin tärkeää ja ehdotetut algoritmit estimoivat onnistuneesti saapuvan signaalin suunnan todellisessa mittausympäristössä. Yhteenvetona voidaan sanoa, että tämä väitöstyö on hyvä lähtökohta suunnanestimointialgoritmitutkimukselle, jonka tavoitteena on parantaa tulevien sukupolvien langattomien verkkojen suorituskykyä ja paikannuksen tarkkuutta

Résumé :

Den tekniska utvecklingen i samhället går snabbare och snabbare, ett påstående knappast någon bestrider nuförtiden. Utvecklingen, inte minst inom dator- och IT-området, påverkar oss alla, oavsett ålder. Inom skolan är datorer ett självklart redskap och begreppet digitala verktyg är inkluderat i grundskolans läroplan inom flera olika ämnen. Denna undersökning syftar till att belysa iPadens roll i grundskolans musikundervisning. För att få svar på om en iPad tillsammans med anpassade appar kan användas som ett musikinstrument i undervisningen, eller till och med ersätta traditionella musikinstrument, så har jag intervjuat tre personer. En representant för utformningen av Skolverkets läroplan för ämnet musik, en rektor inom grundskolan och en ämneslärare i musik på grundskolan får ge sin syn på frågan. Dessa kvalitativa intervjuer ligger till grund för empirin i denna undersökning. Informanternas svar har analyserats med ett hermeneutiskt perspektiv vilket har lett till nya frågor och svar kring iPadens roll i musikundervisningen. Resultatet pekar på att iPads och appar har en självklar roll som verktyg i musikundervisningen men kan inte betecknas som ett musikinstrument. Dock betonar samtliga informanter att svaret kan bli annorlunda i framtiden. Ett tydligt tecken på hur snabbt tekniken utvecklas.
The technical development in society moves faster and faster, a statement no one question nowadays. The development within computer and IT-area affects us all regardless of age. Computers are a natural tool and the concept of digital tools is included in several different subjects in elementary school program. This examination aims to illuminate the role of the iPad in elementary school music education. I have interviewed three individuals to get an answer to the question if an iPad with custom applications can be used as music instrument in education or even replace conventional music instruments. The individuals I have interviewed are: one representative from national agency for education (Skolverket), one principal from elementary school and one music teacher from elementary school. These qualitative interviews are the foundation of the empirical studies in this examination. The answers from this interview have been analyzed via a hermeneutic perspective, which have led to further questions and answers in this matter. The result clearly illustrates that iPads and applications have a given role as a tool in music education but can not be described as a music instrument. Nevertheless, all individuals interviewed underlines that the answer can be different in the future. This is a clear sign of how fast technology develops.

Résumé :

Le fotocamere digitali acquisiscono, manipolano e salvano in memoria informazioni elettronicamente tramite un sensore e unitá di calcolo integrate, rendendo la fotografia accessibile agli utenti finali i quali non necessitano di basi di conoscenza di chimica o delle specifiche operazioni meccaniche che erano necessarie per lo sviluppo con la fotografia analogica. Diversi tipi di degradazioni e artefatti possono affliggere le immagini acquisite tramite camere digitali, riducendo la fedeltà percepita delle immagini e rendendo piú difficili operazioni di visione artificiale che possono essere operate sulle immagini acquisite. Tre elementi possono essere identificati come possibili sorgenti di artefatti in un'immagine: il contenuto della scena, le limitazioni hardware della camera e la pipeline di elaborazione dell’immagine, dall’acquisizione al salvataggio in memoria. Alcuni artefatti non sono direttamente trattati all’interno della tipica pipeline di camera, come ad esempio la presenza di nebbia o pioggia che possono ridurre la visibilitá della scena acquisita. Questi artefatti , per essere trattati, necessitano di metodologie ad hoc che sono generalmente applicate come operazioni post-processing. Altri tipi di artefatti sono legati ai processi di elaborazione dell’immagine e all'intera pipeline di camera integrata nelle camere. Questi artefatti includono il rumore proveniente dal sensore, dominanti cromatiche indesiderate, basso contrasto e artefatti di compressione. L’obiettivo di questa tesi è l'identificazione e la progettazione di nuovi e piú robusti moduli di elaborazione e restauro dell’immagine capaci di migliorare la qualitá delle immagini acquisite dalle camere digitali, in particolare in scenari critici quali condizioni climatiche avverse, condizione di bassa illuminazione etc… Gli artefatti identificati sono divisi in due macro gruppi: “artefatti in-camera” e “artefatti esterni” Nel primo gruppo sono stati identificati e trattati quattro argomenti: la rimozione del rumore proveniente dal sensore della camera, il processo di bilanciamento automatico del bianco, il miglioramento automatico del contrasto e la rimozione di artefatti di compressione JPEG. Il processo di progettazione di questi moduli ha tenuto conto di aspetti di efficienza, in termini di calcolo e memoria occupata, in relazione alla possibilità di integrare tali moduli in future configurazioni di pipeline di camera. Il secondo gruppo di artefatti è legato alla presenza di elementi nella scena che possono causare una degradazione in termini di fedeltà dell’immagine e/o usabilità. In particolare il lavoro presentato nella tesi è focalizzato su artefatti provenienti dalla presenza di pioggia nella scena scattata. La tesi, dopo una descrizione della tipica pipeline di elaborazione delle camere digitali, analizza i diversi tipi di artefatti che possono affliggere la qualità di una immagine, e descrive la progettazione delle soluzioni proposte. Tutti gli approcci proposti sono basati su tecniche di apprendimento automatico, come ad esempio Reti Neurali Convoluzionali o procedure di ottimizzazione Bayesiana, e sono stati validati sperimentalmente su dataset standard. I contributi principali di questa tesi possono essere riassunti in tre punti: integrazione di approcci classici di imaging con tecniche di ottimizzazione basate su machine learning, progettazione e sviluppo di nuovi approcci e architetture di deep learning per il restauro e l'elaborazione di immagini e analisi di metodi di image processing basati su deep learning in task di computer vision.
Digital cameras record, manipulate, and store information electronically through sensors and built-in computers, which makes photography more available to final users which do not anymore need to rely on the use of chemicals and knowledge of mechanical procedures to develop their pictures. Different types of degradation and artifacts can affect images acquired using digital cameras, decreasing the perceptual fidelity of images and making harder many image processing and analysis tasks that can be performed on the collected images. Three elements can be identified as possible sources of artifacts in an image: the scene content, the hardware limitations and flaws, and finally the operations performed by the digital camera processing pipeline itself, from acquisition to compression and storing. Some artifacts are not directly treated in the typical camera processing pipeline, such as the presence of haze or rain that can reduce visibility of the scene in the depicted images. These artifacts require the design of ad hoc methods that are usually applied as post-processing on the acquired images. Other types of artifacts are related to the imaging process and to the image processing pipeline implemented on board of digital cameras. These include sensor noise, undesirable color cast, poor contrast and compression artifacts. The objective of this thesis is the identification and design of new and more robust modules for image processing and restoration that can improve the quality of the acquired images, in particular in critical scenarios such as adverse weather conditions, poor light in the scene etc… . The artifacts identified are divided into two main groups: “in camera-generated artifacts" and “external artifacts and problems". In the first group it has been identified and addressed four main issues: sensor camera noise removal, automatic white balancing, automatic contrast enhancement and compression artifacts removal. The design process of the proposed solutions has considered efficiency aspects, due to the possibility of directly integrating them in future camera pipelines. The second group of artifacts are related to the presence of elements in the scene which may cause a degradation in terms of visual fidelity and/or usability of the images. In particular the focus is on artifacts induced by the presence of rain in the scene. The thesis, after a brief review of the digital camera processing pipeline, analyzes the different types of artifacts that can affect image quality, and describes the design of the proposed solutions. All the proposed approaches are based on machine learning techniques, such as Convolutional Neural Networks and Bayesian optimization procedure, and are experimentally validated on standard images datasets. The overall contributions of this thesis can be summarized in three points: integration of classical imaging approaches with machine learning optimization techniques, design of novel deep learning architectures and approaches and analysis and application of deep learning image processing algorithms in other computer vision tasks.

Mobile apps are useful tools for many different purposes. In agriculture, apps can be used to check the weather and markets, control irrigation, and monitor machine activity among other uses. This research project is a collaboration between Kansas State University and AGCO and includes the development of two apps, using MIT Application Inventor and Google App Engine. Kansas State University was responsible for developing the apps user interface and functionality while AGCO provide the data needs for the apps through Google App Engine. The first app is called Crop Maturity App and measures Growing Degree Days from a crops planting date. The second app is called Combine Efficiency App and determines the performance of a combine harvesting based on its speed. AGCO provided the server support for these apps from a weather service and their own combines that are connected. This project demonstrates the possibility of an open-source development environment with AGCO machine data.

Résumé :

The main purpose of this thesis is to evaluate and compare existing serviceproviders of in-app payment solutions and their APIs, and then concludewhat would be the best choice for hobby developers when deciding on whatservice provider to use for their application.We gained hands-on experience by developing a simple Quiz game appthat featured the implementation of in-app purchase. We took a look atthe major service providers; Apple, Google, PayPal and Windows to getrelevant information and evaluate them based on a comparison model that wecreated. The comparison model consists of a business and a technical aspect,and within of those aspects we chose the most relevant properties that arenecessary to give a fair comparison. We conducted a survey among hobbydevelopers - both students and IT-employees - in order to get insight on whichproperties within in-app payment they considered as the most importantones. With these results we were able to find some indications on which ofthe service providers are best suited for the hobby developer.The survey indicated that easy distribution, good documentation andguides along with an easy development process was the most important aspectsamong our participants. Surprisingly, the importance of potential profitwas rather lower than we expected. Based on what we learned from the surveyand the differences we observed during the evaluation of the differentservice providers we concluded that the best suited in-app payment providerfor the hobby developer is Google?s solution.

Datorer till varje elev blir allt vanligare i gymnasieskolan. Med datorn följer oändliga möjligheter till undervisning och lärande men också många dilemman för lärare. Det finns ofta en övertro på att modern teknik ska ”fixa” dessa pedagogiska dilemman och att lärare med automatik ska veta hur tekniken ska användas. Forskning kring elever i läs- och skrivsvårigheter berättar att det finns många fördelar att vinna med användning av teknologiska verktyg i undervisningen. Motivation, ökat självförtroende, ökade möjligheter till lärande och bättre skolresultat för elever i svårigheter men också för övriga elever. Pedagogiska appar är uppbyggda enligt teorin kring scaffolding och kan, rätt använda, utöka varje elevs ”zone of proximate development”. Syftet med detta examensarbete är att genom en enkät riktad till elever i gymnasieskolan undersöka deras användning av teknologiska verktyg, pedagogiska appar samt deras uppfattning kring nyttan av dessa. Resultatet visar att nästan alla elever använder PC, tillhandahållna av skolorna, men att det främst är inom ämnena svenska och engelska de använder stöd i form av stavningshjälp, uppläst text mm. Användning och kännedom av och kring appar och stödjande program är lågt, även om många av eleverna anger att de har svårigheter att stava så anger endast 10% att de regelbundet använder sig av stöd för stavning. Användningen är alltså låg även fast resultatet också visar på att eleverna upplever positiva effekter av användningen av teknologiska verktyg i form av bland annat ökad motivation och kontroll. Resultatet ger upphov till en mängd frågor rörande orsaken till det låga användandet. Bland annat: har lärarna för låg teknisk kompetens? För låg kännedom kring vilken app som passar bäst och hur den används? Köper skolorna in fel verktyg? Ger vi elever i svårigheter de stöd och kompetenser som möjliggör ett gott studieresultat samt ett framtida fungerande samhällsliv?
A computer for every student is more and more common in high school. With the computer come endless possibilities for teaching and learning but also many dilemmas for teachers. There is often an over-reliance on technology to “fix” these educational dilemmas and that teachers automatically will know how to use this new technology. Research on students with reading and writing disorder show that there are many advantages to gain with the use of educational technology. Motivation, increased self confidence, more possibilities for learning and better school results for students in need but also for other students. Educational apps are constructed according to the theory of scaffolding and can, if used correctly, increase every student’s ”zone of proximate development”. The purpose of this essay is, through the means of a survey aimed at high school/ upper secondary students, examine their use of educational technology and apps and also their perception of the possible gain of these. The results show that nearly every student use a computer/PC made available from their schools. However it is almost exclusively in the subjects Swedish and English they use any support in the form of spelling apps or text read out loud. Usage and knowledge of apps and other supportive software are low. Even if many students answer that they have difficulties in spelling only 10 % say that they regularly use any support when spelling. So the usage is low although the study also shows that the students perceive positive effects from using educational technology, taking the form of increased motivation and control. Our result gives rise to a number of questions concerning the cause of the low usage. Among others: Do teachers have too little technological knowledge and competence? Do they know too little about how to use apps or what app to use? Do schools buy the wrong technological tools for their students? Do we really give students with reading or writing disorder the support and knowledge that would achieve school success and later a working social life?

Résumé :

Detta examensarbete, på kandidatnivå med omfattning 15 högskolepoäng har pågått i tio veckor och har varit i samarbete med Region Gotland. Uppdraget har handlat om att ta fram en ny parkerings skylt för Visbys innerstad samt underlätta navigeringen i trafiken genom en parkerings app. Skylten och appen samspelas med varandra och skapar på så vis en helhet över trafikproblemen i Visby innerstad. Problemformuleringen i projektet har varit: ”Hur kan jag skapa ett nytt navigeringssätt för att underlätta trafik flödet i Visby samt utveckla en ny parkeringsskylt som enkelt kan uppfattas och samtidigt smälta in i den historiska miljön med rimlig kostnads insatser för Region Gotland?” Jag har genom studier på färg, form, funktion analyserat och kommit fram till en grafisk symbol, med ett färgval som är igenkännbart till skyltar relaterat till parkerings automater anpassad för Visbys innerstad. Man ska enkelt kunna tolka skyltarna och hitta till parkerings automaterna samtidigt som det ska smälta in i kulturarvs miljö. Man ska även kunna få information om det är full parkerat, få vägbeskrivning till närmaste parkerings plats och så vidare genom parkerings appen. Utvecklingen av parkerings appen uppkom för att fullända och underlätta trafiken och navigeringen i Visby där den ger en mer samlad information. Projektet har varit anpassade till människa utifrån ergonomisk perspektiv och till den historiska omgivningen i Visby med rimliga åtgärder för Region Gotland.
In this examination project, at candidate level with extent of 15 credits has been going on for ten weeks and been in collaboration with the municipality of Gotland, Region Gotland.This assignment has been about developing a new parking sign for Visby’s inner town and to facilitate navigation in traffic through a parking app. The parking sign and the app interact with each other and create a unity over the traffic problems in Visby. The problem formulation of the project has been:“How can I develop a new navigational system to facilitate the traffic flow in Visby and a new parking sign that is easily understood, while blending in with the cultural heritage with reasonable measures for Region Gotland to produce?” I have through studies of color, form, function analyzed and come up with a graphic symbol, in a choice that is recognizable to the signs related to parking machines and payment of them adapted for Visby’s inner town as well as it should blend in with the environment. You should easily be able to interpret the signs and find the parking machines as well as the parking app gives you direction to the nearest parking space and inform you if any parking spaces are available or not, all this give you more comprehensive and facilitate information.The project has been adapted to human from an ergonomic perspective and the cultural heritage of Visby old town, with reasonable measures for the municipality to realize and produce.

Bakgrund: Behovet av sjukvård ökar internationellt och allt fler av de vårdsökande är personer med långvarig sjukdom. Detta ökar kravet på vården och vårdpersonalen men även på de vårdsökande personerna. Egenvård är ett sätt att hantera detta och tas fram tillsammans med den enskilda personen och sjukvårdspersonalen. Ett nytt verktyg inom egenvård är m-hälsa där appar används som loggbok, övervakning och ett sätt att kommunicera med personer i samma situation och med vårdpersonal. Syfte: Beskriva hur personer med långvarig sjukdom upplever användandet av m- hälsa vid egenvård. Metod: Litteraturöversikt baserad på 14 kvalitativa artiklar funna i databaserna Pubmed, Cinahl, och Medline. Resultat: Deltagarna såg m- hälsa som ett hjälpmedel vid hanteringen av sin långvariga sjukdom. Motivationen till användningen under en längre tid minskade dock och även ökad stress och ångest var förekommande bland användarna. Diskussion: M-hälsa uppfattades till stora delar som en positiv upplevelse då personerna med långvarig sjukdom fick en bättre överblick av sitt tillstånd. De kunde lättare se hur övningar gav resultat i mätvärden och se tidiga varningstecken på en försämring av sitt tillstånd. Det fanns även de som upplevde att m-hälsa skapade ett beroende av tekniken och därmed minskade själv- ständigheten i sin sjukdom.
Background: The need of healthcare is growing all over the world and the amount of people with chronic diseases increases. This causes more pressure on the healthcare and the personnel, but also on the patients. Self-care is a growing phe- nomenon in healthcare; the way to manage self-care is different for everyone and is developed with healthcare personnel and the patient. A new tool used is m-health; in the m-health applications diaries, monitoring, and a way to communicate with other people in the same situation and with healthcare personnel. Aim: Describe how peo- ple with chronic deceases experience m-health during self-care. Method: Literature review based on fourteen articles from the databases; PubMed, Cinahl, and Medline. Result: The attendants saw m-health as a tool for self-care. The motivation was though decreasing during a long-term use and increased feelings of anxiety and stress was describes from some of the users. Discussion: M-health was mostly a positive experience for the attendants and they got a better overview of their disease and early warning signs if the illness was aggra- vating. The downside of m-health was the feeling of being addicted to the technology and that was lowering the feeling of independents.

Résumé :

Mobile applications stores such as Apple’s App Store and Google’s Android Market revolutionized the distribution of applications for mobile devices. However, with thousands of application submissions, limited testing resources and the lack of an effective filtering mechanism, application stores suffer from information overload and a risk of releasing poor quality applications that could create confusion to consumers and may seriously affect the App store markets. Thus concern has been raised whether applications have been developed according to the need and interest of consumers. Therefore, the purpose of this study was mainly to identify and get insight into the main factors that mobile application consumer takes into consideration when purchasing mobile applications from the desktop iTunes App Store and the mobile App Store on the iOS devices: iPhone, iPad and iPod Touch. In this study both qualitative and quantitative case study approach was used. Accordingly twelve participants were selected from Stockholm and Uppsala area and their behaviour in the Apple’s App Store from the desktop iTunes and the mobile App Store on iOS devices was observed and recorded. Additionally questionnaires were administered to all participants in order to gather the necessary information. Consumers on the App Store behave differently depending on the unit they are using. This is because applications on the App Store are presented differently in the desktop iTunes App Store and the mobile App Store on the iOS devices. The study shows that young consumers with lower income purchase apps more frequently than the consumers with higher income. It also shows that consumers often consider the description, the screenshots, and the ratings when they are interested in buying applications. Furthermore consumers take a look more on ratings in the list on the iPhone and iPad App Store because the ratings are not shown in the list on the iTunes App Store. Similarly consumers tend to read the customer reviews more on the iTunes and iPad App Store as the customer reviews on the iPhone App Store is displayed in another page. Consumers were found to be more attracted by visual elements that they are already familiarized with, apps with famous logos and known fonts and styles but also to coherent and descriptive app names and strong colors (i.e. red, green, yellow, black and blue, respectively). The majority of the participants found the iTunes App Store messy and cumbersome to use. They preferred using the iPad App Store because they found it to be a good mixture of both iTunes and iPhone App Store but also because it has more options to consider. Although consumers behave differently depending on the unit they are using, the visual element of the apps, prior knowledge of consumers about the name of the apps, ratings, easy accessibility of screenshots and customer reviews of the apps were found to be the main factors to be considered by consumers when they visit app stores for purchase. Thus application developers and digital magazine publishers should consider these consumer behaviours in order to influence more downloads and successfully sell apps on the app stores.

Résumé :

AbstractIn this chapter, we highlight the added value of mobile and web apps to the field of citizen science. We provide an overview of app types and their functionalities to facilitate appropriate app selection for citizen science projects. We identify different app types according to methodology, data specifics, and data collection format.The chapter outlines good practices for creating apps. Citizen science apps need to ensure high levels of performance and usability. Social features for citizen science projects with a focus on mobile apps are helpful for user motivation and immersion and, also, can improve data quality via community feedback. The design, look and feel, and project identity are essential features of citizen science apps.We provide recommendations aimed at establishing good practice in citizen science app development. We also highlight future developments in technology and, in particular, how artificial intelligence (AI) and machine learning (ML) can impact citizen science projects.

Résumé :

AbstractA key rationale for Apple and Google’s app stores was that they curate apps to ensure that they do not contain malware. Curation has gone beyond this goal and now unduly constrains the apps that you can use on your smartphone. It needs to stop. App quality should be ensured with other techniques and by a wider range of organizations than just Apple and Google.

Résumé :

ZusammenfassungGamifizierungsstrategien werden in Fitness-, Gesundheits- und Wohlbefindens-Apps weitläufig eingesetzt. In diesem Text wird untersucht, ob und inwieweit Gamifizierungen ethisch problematische Formen von Einflussnahme darstellen können. Dabei besteht zum einen die Gefahr, dass sie in der Motivation der Nutzer:innen auf unzulässige Formen von Paternalismus zurückgreifen. Zum anderen könnten hier ethisch bedenkliche Manipulationsstrategien im Spiel sein, wenn Apps versuchen, Nutzer:innen möglichst lange in der App zu halten und zur vermehrten Datenpreisgabe zu bewegen. Im Text wird dafür argumentiert, dass dies vor allem a) von der Schwere der motivationalen Effekte, b) dem Grad ihrer Erkennbarkeit, c) der Übereinstimmung der Ziele von Nutzer:in und App-Betreiber:innen, sowie d) der Wahrscheinlichkeit und Schwere unintendierter Nebenfolgen abhängt.

AbstractIn this chapter, I describe my journey of becoming a user of menstrual tracking apps. I explore how my positionality and the different encounters I have had prior to and during this journey have shaped my understanding and experience of using the app. I am reflexive about how my standpoint constituted my meaning-making processes. I emphasize that through the journey of self-tracking, knowledge was developed in conversation with other users of these apps. I reflect on the tensions I face with regards to giving away personal data to the health app about my body while questioning the advertised possibilities to build body awareness and knowledge through digital traces. My chapter concludes by assessing my methodological choices, stressing the possibilities and limitations of a reflective writing.

Résumé :

Abstract Mobile app development has been considered as one of the fastest growing segments of the software industry both worldwide and in Saudi Arabia. Due to their pervasiveness, mobile applications call for consideration of complex and rapidly changing requirements given the diversity of their environments. Therefore, agile is considered the most suitable methodology for developing mobile apps. However, little research has investigated agile adoption in mobile app development in the real context. Therefore, the purpose of this PhD is to investigate the factors that have a significant impact on agile adoption in mobile app development by small and medium-size software organisations in Saudi Arabia. The expected key contribution of this research will be a deep insight into agile adoption in mobile app development, and the design and development of tools and techniques that may support agile adoption within Saudi context.

Résumé :

Abstract Failure Analysis (FA) is a complex activity that requires careful and complete documentation of all findings and conclusions to preserve knowledge acquired by engineers in this process. Modern FA systems store this data in text or image formats and organize it in databases, file shares, wikis, or other human-readable forms. Given a large volume of generated FA data, navigating it or searching for particular information is hard since machines cannot process the stored knowledge automatically and require much interaction with experts. In this paper, we investigate applications of modern Natural Language Processing (NLP) approaches to the classification of FA texts with respect to electrical and/or physical failures they describe. In particular, we study the efficiency of pretrained Language Models (LM) in the semiconductors domain for text classification with deep neural networks. Evaluation results of LMs show that their vocabulary is not suitable for FA applications, and the best classification accuracy of appr. 60% and 70% for physical and electrical failures, respectively, can only be reached with fine-tuning techniques.

Résumé :

[This Proceedings paper was revised and published in the journal Issues in Informing Science and Information Technology] Aim/Purpose: Despite millions of apps on the market, it is still challenging to develop a mobile app that can run across platforms using the same code. Background: This paper explores a potential solution for developing cross platform apps by presenting the hybrid app approach. Methodology: The paper first describes a brief evolution of the different mobile app development approaches and then compares them with the hybrid app approach. Next, it focuses on one specific hybrid app development framework called Ionic. Contribution: The paper presents the hybrid app approach as an emerging trend in mobile app development and concludes with the highlight of its advantages and teaching implications. Findings: The hybrid app approach reduces the learning curve and offers tools to allow the reuse of code to create apps for different mobile devices. Recommendations for Practitioners: The experience that the paper describes in using Ionic framework to create a hybrid app can be adopted in a web design or mobile app development course. Impact on Society: The advance in hybrid framework in general and the growing acceptance of open source framework, such as Ionic in particular, may provide an alternative to the native app domination and may trigger the rapid rise of hybrid apps in the years to come.

Résumé :

Diagnostic and contact tracing apps are an important weapon against contagion during a pandemic. We study how the content of the messages used to promote the apps influences adoption by conducting a survey experiment on approximately 23,000 Mexican adults. Respondents were randomly assigned to one of three different prompts, or a control condition, before stating their willingness to adopt a diagnostic app and contact-tracing app. The prompt emphasizing government efforts to ensure data privacy, which has been one of the most common strategies, reduced willingness to adopt the diagnostic app by about 4 percentage points and the contact tracing app by 3 percentage points. An effective app promotion policy must understand individuals' reservations and be wary of unintended reactions to naive reassurances.

Résumé :

Background. Mental health mobile applications (apps) have the potential to expand the provision of mental health and wellness services to traditionally underserved populations. There is a lack of guidance on how to choose wisely from the thousands of mental health apps without clear evidence of safety, efficacy, and consumer protections. Purpose. This Technical Brief proposes a framework to assess mental health mobile applications with the aim to facilitate selection of apps. The results of applying the framework will yield summary statements on the strengths and limitations of the apps and are intended for use by providers and patients/caregivers. Methods. We reviewed systematic reviews of mental health apps and reviewed published and gray literature on mental health app frameworks, and we conducted four Key Informant group discussions to identify gaps in existing mental health frameworks and key framework criteria. These reviews and discussions informed the development of a draft framework to assess mental health apps. Iterative testing and refinement of the framework was done in seven successive rounds through double application of the framework to a total of 45 apps. Items in the framework with an interrater reliability under 90 percent were discussed among the evaluation team for revisions of the framework or guidance. Findings. Our review of the existing frameworks identified gaps in the assessment of risks that users may face from apps, such as privacy and security disclosures and regulatory safeguards to protect the users. Key Informant discussions identified priority criteria to include in the framework, including safety and efficacy of mental health apps. We developed the Framework to Assist Stakeholders in Technology Evaluation for Recovery (FASTER) to Mental Health and Wellness and it comprises three sections: Section 1. Risks and Mitigation Strategies, assesses the integrity and risk profile of the app; Section 2.
