Recent advances in monocular model-based tracking: a systematic literature review

In this paper, we review the advances of monocular model-based tracking for last ten years period until 2014. In 2005, Lepetit, et. al, [19] reviewed the status of monocular model based rigid body tracking. Since then, direct 3D tracking has become quite popular research area, but monocular model-based tracking should still not be forgotten. We mainly focus on tracking, which could be applied to aug- mented reality, but also some other applications are covered. Given the wide subject area this paper tries to give a broad view on the research that has been conducted, giving the reader an introduction to the different disciplines that are tightly related to model-based tracking. The work has been conducted by searching through well known academic search databases in a systematic manner, and by selecting certain publications for closer examination. We analyze the results by dividing the found papers into different categories by their way of implementation. The issues which have not yet been solved are discussed. We also discuss on emerging model-based methods such as fusing different types of features and region-based pose estimation which could show the way for future research in this subject.

Map matching by using inertial sensors: literature review

This literature review aims to clarify what is known about map matching by using inertial sensors and what are the requirements for map matching, inertial sensors, placement and possible complementary position technology. The target is to develop a wearable location system that can position itself within a complex construction environment automatically with the aid of an accurate building model. The wearable location system should work on a tablet computer which is running an augmented reality (AR) solution and is capable of track and visualize 3D-CAD models in real environment. The wearable location system is needed to support the system in initialization of the accurate camera pose calculation and automatically finding the right location in the 3D-CAD model. One type of sensor which does seem applicable to people tracking is inertial measurement unit (IMU). The IMU sensors in aerospace applications, based on laser based gyroscopes, are big but provide a very accurate position estimation with a limited drift. Small and light units such as those based on Micro-Electro-Mechanical (MEMS) sensors are becoming very popular, but they have a significant bias and therefore suffer from large drifts and require method for calibration like map matching. The system requires very little fixed infrastructure, the monetary cost is proportional to the number of users, rather than to the coverage area as is the case for traditional absolute indoor location systems.

Depth sensors in augmented reality solutions. Literature review

The emergence of depth sensors has made it possible to track – not only monocular cues – but also the actual depth values of the environment. This is especially useful in augmented reality solutions, where the position and orientation (pose) of the observer need to be accurately determined. This allows virtual objects to be installed to the view of the user through, for example, a screen of a tablet or augmented reality glasses (e.g. Google glass, etc.). Although the early 3D sensors have been physically quite large, the size of these sensors is decreasing, and possibly – eventually – a 3D sensor could be embedded – for example – to augmented reality glasses. The wider subject area considered in this review is 3D SLAM methods, which take advantage of the 3D information available by modern RGB-D sensors, such as Microsoft Kinect. Thus the review for SLAM (Simultaneous Localization and Mapping) and 3D tracking in augmented reality is a timely subject. We also try to find out the limitations and possibilities of different tracking methods, and how they should be improved, in order to allow efficient integration of the methods to the augmented reality solutions of the future.

Inter-jurisdictional fiscal competition: a review of the literature and policy recommendations

This paper surveys the literature on fiscal competition. We consider tax and expenditure competition in a more general set up where different jurisdictions within a federation may compete in the provision of public goods in order to attract some residents (Tiebout, 1956) and expel others (Brueckner, 1999); and/or for business. We address the vast literature on welfare gains or losses of these types of competition. Then, we discuss the empirical evidence, focusing on estimates of the sensitiveness of production factors to tax differentials and on the importance of the strategic interdependence among jurisdictions. We combine econometric studies with some case studies. Last we discuss the design of mechanisms to cope with fiscal competition, especially under a more global environment where factors become more mobile.

What is the current state of cloud service research and its promise for the future? A systematic literature review

The information technology (IT) industry has recently witnessed the proliferation of cloud services, which have allowed IT service providers to deliver on-demand resources to customers over the Internet. This frees both service providers and consumers from traditional IT-related burdens such as capital and operating expenses and allows them to respond rapidly to new opportunities in the market. Due to the popularity and growth of cloud services, numerous researchers have conducted studies on various aspects of cloud services, both positive and negative. However, none of those studies have connected all relevant information to provide a holistic picture of the current state of cloud service research. This study aims to investigate that current situation and propose the most promising future directions. In order to determine achieve these goals, a systematic literature review was conducted on studies with a primary focus on cloud services. Based on carefully crafted inclusion criteria, 52 articles from highly credible online sources were selected for the review. To define the main focus of the review and facilitate the analysis of literature, a conceptual framework with five main factors was proposed. The selected articles were organized under the factors of the proposed framework and then synthesized using a narrative technique. The results of this systematic review indicate that the impacts of cloud services on enterprises were the factor best covered by contemporary research. Researchers were able to present valuable findings about how cloud services impact various aspects of enterprises such as governance, performance, and security. By contrast, the role of service provider sub-contractors in the cloud service market remains largely uninvestigated, as do cloud-based enterprise software and cloud-based office systems for consumers. Moreover, the results also show that researchers should pay more attention to the integration of cloud services into legacy IT systems to facilitate the adoption of cloud services by enterprise users. After the literature synthesis, the present study proposed several promising directions for cloud service research by outlining research questions for the underexplored areas of cloud services, in order to facilitate the development of cloud service markets in the future.

Memory mixed with desire : a preliminary study of philosophy and literature in the works of Friedrich Nietzsche and Milan Kundera

Memory Mixed with Desire: A preliminary study of Philosophy and Literature in the works of Friedrich Nietzsche and Milan Kundera Robert Spinelli Brock University, Department of Philosophy This thesis studies intertextuality in the works of Friedrich Nietzsche and Milan Kundera through the primary themes of memory and forgetting. The thesis starts with two introductory chapters that delineate memory according to Nietzsche and Kundera respectively. From here, I move into a discussion of Nietzsche's Ubermensch as an example of the type of forgetting that Nietzsche sees as a cure for the overabundance of memory that has led to Christian morality. Next, I explore the Kunderan concept of kitsch as the polar opposite of what Nietzsche has sought in his philosophy, finishing the chapter by tying the two thinkers together in a Kunderan critique of Nietzsche. The thesis ends with a chapter devoted to the Eternal Return beginning with an exegesis of Nietzsche's idea and ending with a similar exegesis of Kundera's treatment of this thought. What I suggest in this chapter is that the Eternal Return might itself be a form of kitsch even in its attempt to revalue existence.

Emptying the bell jar: an exploration of adolescent responses to a women's literature unit /

This study examines adolescent student responses to a women's literature unit taught within a grade 12 Writer's Craft course. Current research (Gilligan, 1989, Pipher, 1994 & Slack, 1999) suggests that there is a great under-representation of female authors in the high school literature curriculum. The use of women's literature may draw attention to important literary figures who are historically overlooked within the curriculum. It gives voice to a marginalized group and presents students with alternative subjects and heroes. It encourages students to develop a critical perspective and reevaluate assumptions about institutions, ideologies, language and culture. It also allows me, as a teacher, to reflect on my own teaching practices and explore alternate feminist pedagogical principles and teaching styles encouraging multiplicity of voices, deconstruction of power relations, and alternative assessment tools within the classroom. As an educator, it is important for me to teach curriculum that is relevant and meaningful to students and help them become critical, self-reflective thinkers. It is also important for me to assist students in their exploration of self and encourage them to expand their awareness of historical, social and global issues. Sylvia Plath's (1963) The belljar is used as the primary text taught within this unit. In this novel, the bell jar is a central image that signifies entrapment and isolation. "To the person in the bell jar, blank and stopped as a dead body, the world itself is the bad dream"(p.l 54). As a metaphor, the bell jar resonates with young readers in a variety of ways.

A conceptual analysis of research literature on teachers' ideology and literacy practices: extending the dialogue through a secondary analysis of high school English as an additional language contexts /

This thesis provides a conceptual analysis of research literature on teachers' ideology and literacy practices as well as a secondary analysis of three empirical studies and the ways in which the ideologies of the English as an Additional Language (EAL) (Street, 2005) teachers in these contexts impact the teaching of literacy in empowering/disabling ways. Several major theoretical components of Cummins (1996, 2000), Gee (1996, 2004) and Street (1995, 2001) are examined and integrated into a conceptual triad consisting of three main areas: power and ideology, validation of students ' cultural and linguistic backgrounds, and teaching that empowers. This triad provides the framework for the secondary analysis of three empirical studies on the ideologies of secondary EAL teachers. Implications of the findings from the conceptual and secondary analyses are examined in light of the research community and secondary school teachers of EAL.

The impact of a digital children's literature program on primary students' reading motivation

This qualitative study stemmed from a concern of the perceived decline in students' reading motivation after the early years of schooling, which has been attributed to the disconnect between the media students are accustomed to using outside the classroom and the media they predominantly use within the classroom. This research documented the effectiveness of a digital children's literature program and a postreading multimedia program on eight grade 1 students' reading motivation, word recognition, and comprehension abilities. Eight students were given ten 25-minute sessions with the software program over 15 weeks. Preprogram, interim-program, and postprogram qualitative data were collected from students, teachers, and parents through questionnaires, interviews, standardized reading assessment tools, classroom observations, field notes, and student behaviour observation checklists. Findings are summarized into 3 themes. The motivational aspects and constructivist styles of instruction in the digital reading programs may have contributed to 5 student participants' increased participation in online storybook reading at home. Qualitative data revealed that the digital children's literature program and multimedia postreading activities seemed to have a positive influence on the majority of grade 1 student participants' reading motivation, word recognition, and listening comprehension skills. These findings suggest the promise of multimedia and Internet-based reading software programs in supporting students with reading andlor behavioural difficulties. In keeping with current educational initiatives and efforts, increased use of media literacy practices in the grade 1 curriculum is suggested.

Gender and Healing in the Hippocratic Corpus

Hippocratic physicians sought to establish themselves as medical authorities in ancient Greece. An examination of the deontological texts of the Hippocratic corpus reveals that the Hippocratics created a medical authority based on elite male characteristics. The key quality of the Hippocratic physician was sōphrosunē, a quality closely associated with men and used in the differentiation of genders in the Greek world. Women were not believed to innately possess this quality and so their healing activities were restricted within the Hippocratic framework. Women’s healing activities are only mentioned in the corpus when women are involved in the treatment of other women or self-treatment. The Hippocratic construction of medicine as a male domain fit within a Classical cultural framework, as the cultural anxiety concerning women healers and women’s use of pharmaka are evident in both Greek myth and literature.

In danger of jammed minds: A deconstructive discourse analysis of the criteria for early onset schizophrenia and imagination in children's literature

The purpose of this research is to expose and complicate those discourses of childhood imagination as demonstrated in the diagnostic criteria for early onset schizophrenia by using an antipsychiatry perspective. This will be done by evaluating those discourses alongside those found in popular children’s literature, specifically, Harry Potter and The Philosopher’s Stone, Bridge to Terabithia, and A Wrinkle in Time. Once uncovered, the underlying power discourses were then exposed. This research will then employ a minor reading as provided by Deleuze and Guattari’s (1987) approach to minor literature to demonstrate the ways in which the child can subvert those dominant discourses. The potential of literature is evaluated for its ability to provide alternative modes of experience and lines of flight for the child subjected to the diagnostic criteria of schizophrenia.

Using First Nations Children's Literature in the Classroom: Portfolio of Learning

A portfolio was developed to encourage teachers of Aboriginal children to include First Nations mentor texts into their daily teaching practices. The artifacts within the portfolio have been produced in accordance with guiding beliefs about how students, specifically First Nations students, learn. The portfolio supports the notion that Aboriginal children need to encounter representations of their own culture, histories and beliefs within the literature in order to be successful in school. The use of First Nations children’s literature in the classroom was explored with an emphasis on how using this literature will assist in improving literacy levels and the self-esteem of First Nations students.
