W3C Geolocation API ur ett utvecklarperspektiv

The goal of this thesis is to investigate the W3C Geolocation API from a developer?s perspective, focused on whether it makes development of location-based applications more accessible to developers. This has been investigated by looking at available ways to locate, possible uses, the functionality offered, the necessary level of prior knowledge needed for a developer and requirements on developer tools. This has been achieved through studies in relevant areas, a thorough introduction to W3C Geolocation API functionality, and by using the API to develop two different location-based applications as a demonstration. Testing of applications, on different platforms and in different environments, in conjunction with investigation of the rest of the material has shown that W3C Geolocation API in many ways actually makes development of location-based applications more accessible for developers. The API also provides fully adequate functionality and quality to meet the requirements for development of both simple and very advanced location-based applications. Målet med denna uppsats är att undersöka W3C Geolocation API ur ett utvecklarperspektiv, fokuserat på om den gör utveckling av positionsbaserade applikationer mer tillgänglig för utvecklare.

Viljebegreppet och psykologin : En studie av psykologins framväxt som vetenskap i Sverige genom en analys av viljebegreppets betydelseförändring

The aim of this study is to elucidate the process in which psychology was separated from philosophy and established itself as a distinct academic discipline in Sweden. I argue that the concept of will, as well as the concepts of thinking and emotion, have a lot to tell us about the rise of academic psychology in Sweden. This is done through an analysis of psychology textbooks, encyclopaedia-articles and academic texts on the themes will and psychology, from around 1800 till 1950.Prior to the establishment of the first chair of psychology in Uppsala 1948, the discipline was above all a part of the philosophical discipline. For psychology to become a science of its own, it was crucial to obtain a position among the empirical sciences. It thus had to distance itself from philosophy, and in particular from metaphysics.

Vad påverkar medieteknikstudenternas kursval?

With many different elective courses to choose between, a lot of students  experience anxiety over deciding which courses to study next semester. The  choice of a specific course can have a big impact on the students future studies  and/or employment. Therefore the anxiety is justified. At the same time the  number of students applying for a course often vary from year to year. This  creates issues for the responsible teachers because of the ever-changing  resource requirements.There are several different theories on decision making, addressing the  different time related states as well as the different habitual styles.

Enhetstestning: Kostnad mot kvalitet

Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.

Förföljelse på grund av kön : En analys av hur kön som skyddsgrund tillvaratar kvinnors skyddsbehov

In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.

Den avgränsade krisen : En gränsdragningsanalys av Lindbeckkommissionens rapport Nya villkor för ekonomi och politik (SOU 1993:16)

During Sweden's economic crisis in the early 1990s a governmental committe of prominent economic and political experts were gathered to produce an analysis of and suggestions to the solution of that crisis. The committe produced a report that became widely commented in the media and in parliment. The report anc the reception of it gives us insights in how the boundaries between social science and politics are created an how new fields of expertise is added to a science. This thesis uses a constructivist approach to explore how the techniques of the economic science were made into credible means of knowöedge production outside of the field where it traditionally holds epistemological authority. Working from the assumption that language does things to the objects that it describes I claim that the episode investigated in this thesis was shaped by the committee's ability to define the economic crissi and thus making it into a knowable object.

Sambandet mellan parodontit och KOL

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.

Statistik, nyckeltal och mätmetoder ? Vad ger de för bild av bibliotekens verksamhet?

The aim of this Bachelor´s thesis is to investigate how library statistics, performance measurement and indicators represent the modern public library activity. During the last decades the public library has gone through a lot of changes. Information overall has increased and new technology has been introduced into the library. This new development has had effects on the library users. The statistics reported to the Statens kulturråd (National Arts Council) has not changed in the same way.

Project: Knowledge. A two-sided perspective on knowledge transfer & knowledge creation

Purpose: Our purpose is to describe and understand how a project-based, knowledge-intensive firm in the high-technology industry creates and transfers knowledge, seen from two perspectives.Methodology: Our qualitative case study has an explorative approach since earlier studies within our positioning are absent, thus we look at KM abductively. To gain more depth to our study, we mirror our findings from our case company with data collected from three additional organisations.Theoretical perspectives: We see a clear distinction between researchers, either seeing knowledge as an object or a process. Thus, we review theories from both sides, either focusing on the creation or transferring of knowledge. In addition, theories on KM in project organisations areaccounted for.Empirical foundation: The study is based on the empirical foundation which consists of the data received through six interviews with employees at our main case company and, additionally, two interviews at each of our three mirrorcompanies.Conclusion: The study found KM being seen from both perspectives in all four firms. Through this, we found implications for how our case company could proceed in the future..

Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology

In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.
