Reconocimiento de gestos corporales, utilizando procesamiento digital de imágenes para activar sistema de alarmaMoreno Moreno, Flavio David January 2015 (has links)
La investigación realizada a los sistemas de seguridad electrónica de edificios, plantea como objetivo principal el reconocimiento de tres gestos de un lenguaje corporal del personal de vigilancia, y la consecuente activación de alarma en forma automática. Inicialmente se realizó una encuesta dirigida a las administraciones y personal de edificios, para saber cuales eran las ocurrencias que vulneraban la seguridad de un edificio multifamiliar, luego se observaron y analizaron las imágenes capturadas por una cámara de vigilancia ubicada en la recepción, identificando las ocurrencias más vulnerables y gestos asociados a dichos eventos; se seleccionaron tres gestos que en forma inconsciente realizaba el personal de vigilancia ante dichas situaciones. A determinados cuadros que comprenden estas imágenes se le aplicaron técnicas de procesamiento espacial, con ayuda de una iluminación artificial que era más intensa en la parte posterior del sujeto de análisis, consiguiéndose la definición de una silueta binarizada en el entorno Matlab, técnicas como selección del plano rojo, plano de bits más significativo, invertir imagen y transformaciones morfológicas tipo cerradura, definieron una silueta que ayudó a desarrollar un algoritmo matemático para generar una señal eléctrica en el puerto serial USB del ordenador, donde se conectó físicamente una plataforma de hardware Arduino que activa la alarma. La elección de esta plataforma se debió a que Matlab cuenta con un grupo de instrucciones para Arduino, con el objetivo de lograr una comunicación sincronizada entre ordenador e interface.
Las técnicas utilizadas reconocieron 62,5% de los eventos descritos en las encuestas realizadas y que no son mencionadas en temas de investigación similar. Para lograr el objetivo fue necesario analizar un cuadro por segundo.
The research poses as their main objective the three gestures recognition of a body language of surveillance personnel and the consequent activation of alarm automatically. It was initially carried out a survey of the administration and the offices of the buildings to know which were the occurrences that violate the security of a multi-family building, then were observed and analyzed images captured by a surveillance camera located in the reception, identifying the most vulnerable occurrences and gestures associated with these events; were selected three gestures that unconsciously performs surveillance personnel before such situations; to certain pictures that comprise these images were applied spatial processing techniques, with the help of an artificial lighting that was more intense in the back of the subject of analysis, getting the definition of a silhouette binarized in the Matlab environment, techniques such as plane selection red, more significant bit plane, to invest an image and convolution close type, defined a silhouette that allowed to develop a mathematical algorithm that generated an electrical signal in USB serial port of the computer, where it is physically connected a hardware platform Arduino that active the alarm.This platform choice is due to the fact that Matlab has a group of instructions for Arduino, achieving an orderly communication between computer and interface.
The techniques used recognized 62.5 % of the events described in the surveys carried out and which aren’t mentioned in similar research topics. To achieve the objective was necessary to analyze a picture per second.

Twentieth-century poetry and science : science in the poetry of Hugh MacDiarmid, Judith Wright, Edwin Morgan, and Miroslav HolubGibson, Donald January 2015 (has links)
The aim of this thesis is to arrive at a characterisation of twentieth century poetry and science by means of a detailed study of the work of four poets who engaged extensively with science and whose writing lives spanned the greater part of the period. The study of science in the work of the four chosen poets, Hugh MacDiarmid (1892 – 1978), Judith Wright (1915 – 2000), Edwin Morgan (1920 – 2010), and Miroslav Holub (1923 – 1998), is preceded by a literature survey and an initial theoretical chapter. This initial part of the thesis outlines the interdisciplinary history of the academic subject of poetry and science, addressing, amongst other things, the challenges presented by the episodes known as the ‘two cultures' and the ‘science wars'. Seeking to offer a perspective on poetry and science more aligned to scientific materialism than is typical in the interdiscipline, a systemic challenge to Thomas Kuhn's The Structure of Scientific Revolutions (1962) is put forward in the first chapter. Additionally, the founding work of poetry and science, I. A. Richards's Science and Poetry (1926), is assessed both in the context in which it was written, and from a contemporary viewpoint; and, as one way to understand science in poetry, a theory of the creative misreading of science is developed, loosely based on Harold Bloom's The Anxiety of Influence (1973). The detailed study of science in poetry commences in Chapter II with Hugh MacDiarmid's late work in English, dating from his period on the Shetland Island of Whalsay (1933 – 1941). The thesis in this chapter is that this work can be seen as a radical integration of poetry and science; this concept is considered in a variety of ways including through a computational model, originally suggested by Robert Crawford. The Australian poet Judith Wright, the subject of Chapter III, is less well known to poetry and science, but a detailed engagement with physics can be identified, including her use of four-dimensional imagery, which has considerable support from background evidence. Biology in her poetry is also studied in the light of recent work by John Holmes. In Chapter IV, science in the poetry of Edwin Morgan is discussed in terms of its origin and development, from the perspective of the mythologised science in his science fiction poetry, and from the ‘hard' technological perspective of his computer poems. Morgan's work is cast in relief by readings which are against the grain of some but not all of his published comments. The thesis rounds on its theme of materialism with the fifth and final chapter which studies the work of Miroslav Holub, a poet and practising scientist in communist-era Prague. Holub's work, it is argued, represents a rare and important literary expression of scientific materialism. The focus on materialism in the thesis is not mechanistic, nor exclusive of the domain of the imagination; instead it frames the contrast between the original science and the transformed poetic version. The thesis is drawn together in a short conclusion.

Role konfliktů u soutěžních tanečních párů v procesu učení se tanci a vliv osobního partnerského vztahu / Conflict resolution among competitive Ballroom dancers in the process of learning and the influence of personal relationshipsVanek, Marián January 2021 (has links)
Basic element of competitive Dance Sport is the dance couple. For being succesful, it's needed to master the combination of specific dance skills, sport skills, stress resilience and skills connected to dance partnership, mainly communication skills and conflict resolution skills. Since the scientific research of conflict resolution among competitive couples is very scarce, aim of our explorative qualitative research is to understand how Latin Dance Sport couples experience conflicts and their subjective meaning of partnership in competitive dance. Experiences of dancers of various dance classes and their trainers were gathered using questionnaire (= 43) and half-structured interviews (= 13). Based on themati analysis, relevant themes were identified and described, and explanatory model further based on activity theory, game theory and theory of interdependence was proposed. Model suggests that contradiction of two different motives (competitive success vs. partner relationship) in the activity systems of competitive dance predisposes possible complex relationships between (implicit and/or explicit) aims of dancers, their type of partnership, possible expressed conflicts and their preferred styles of conflict resolution (based on the unique context of every dance couple). Relevant identified themes...

Handboekouteurs en wiskunde-onderwysers se inlyninterpretasie van die wiskundekurrikulum vir effektiewe klaskamerpraktykVan der Merwe, Wynand Johannes 10 1900 (has links)
Text in Afrikaans, abstract in English and Afrikaans / Due to the radical reform in mathematics education worldwide, the mathematics curriculum
underwent dramatic changes in order to meet the new objectives in mathematics. This has
placed a huge responsibility on curriculum compilers and the authors of mathematics textbooks
and mathematics teachers to enhance the cognitive development of learners.
This study takes the view that:
What happens in the class is what you get.
Based on the above statement, the foundation of mathematics teaching, namely the mathematics
curriculum, the mathematics textbook and the teacher’s instruction in the teaching
venue were scrutinised. During a diagnostic examination of teachers’ interpretation,
knowledge and application of the mathematics curriculum and the content of mathematics textbooks on the East Rand, the following problems regarding mathematics teaching
emerged: The most important finding of TIMMS is that the differences in performance in
mathematics between different countries can be linked to the way teachers interpret and
present the content of mathematics. Research has revealed that the interaction of teachers
with curriculum content follow a dynamic and constructive application instead of direct application
based on the mathematics curriculum.
Teachers often change the prescriptions and order of content in the mathematics curriculum
to suit their teaching style, knowledge and previous experience. Consequently, align application
of mathematical concepts and skills does not take place and this creates a gap in learners’
cognitive development. It also leaves a gap in the application of the Type 5 cognitive
development tasks in mathematics which enable a verifying deductive application of concepts. The action research created a structure which could meet this need.
Authors of mathematics textbooks present their own vision, interpretation and style in mathematics
textbooks, which influences the order of mathematics content and concepts. The
result is that mathematics content and concepts are at times not aligned with representations
in the mathematics curriculum and objectives are therefore not reached. The different interpretations
of mathematics textbooks by teachers differ greatly and these differences place
great pressure on teachers to decide how the mathematics textbook will be used in the
teaching venue. In this study a mathematics textbook profile and a task analysis were formulated in the
cause of action research which will enable teachers to make a professional analysis which
they can use.
Because a variety of mathematics textbooks are selected for use in schools, teachers assume
that these approved mathematics textbooks focus on the curriculum. They therefore
slavishly follow the mathematics textbooks without consulting the mathematics curriculum.
Shortcomings in mathematics textbooks and teachers’ own interpretation of mathematics
content leave a big gap in their own alignment of mathematics teaching.
To satisfy this need, an assessment profile and an methodology for alignment are provided
to enable teachers to monitor the curriculum alignment presentation of concepts and skills. / As gevolg van die radikale hervorming in wiskunde-onderrig wêreldwyd het die
wiskundekurrikulum dramatiese veranderings ondergaan ten einde die nuwe doelstellings in
wiskunde te bereik. Dit het enorme verantwoordelikheid geplaas op kurrikulumsamestellers
en outeurs van wiskundehandboeke en wiskunde-onderwysers om die kognitiewe
ontwikkeling van leerders te bevorder.
In hierdie studie is van die volgende standpunt uitgegaan:
What happens in the class is what you get.
Derhalwe is die fondasie van wiskunde-onderrig, naamlik die wiskundekurrikulum,
wiskundehandboek en die onderwyser se instruksies in die klaskamer ondersoek. In `n
diagnostiese ontleding van onderwysers se interpretasie, kennis en toepassing van die
wiskundekurrikulum en die wiskundehandboekinhoude aan die Oos-Rand het die volgende
probleme in verband met wiskunde-onderrig na vore gekom: Die belangrikste bevinding van
TIMMS is dat die verskille in wiskundeprestasie tussen lande verband hou met die wyse
waarop onderwysers die wiskudekurrikuluminhoude interpreteer en aanbied. Navorsing toon dat die interaksie van onderwysers met kurrikulummateriaal op ʼn dinamiese en
konstruktiewe toepassing geskied in plaas van direkte toepassing vanuit die
wiskundekurrikulum.
Onderwysers verander dikwels die wiskundekurrikulum se voorskrifte en volgorde van
inhoude om by hulle onderrigstyl, kennis en vorige ervarings te pas. Die gevolg is dat geen
inlyntoepassing van wiskundebegrippe en vaardighede plaasvind nie en dit laat ʼn leemte in
leerders se kognitiewe ontwikkeling. Verder laat dit ʼn leemte in die toepassing van die 5-tipe
kognitiewe ontwikkelingstake in wiskunde wat ʼn verifiërend deduktiewe toepassing van
begrippe bewerkstellig. In die aksienavorsing is ʼn struktuur geskep wat in hierdie behoefte
voorsien.
Outeurs van wiskundehandboeke het ʼn eie visie, interpretasie en styl wat hulle in
wiskundehandboeke aanbied. Dit het ʼn invloed op die volgorde van wiskunde-inhoude en begrippe en gevolglik is wiskunde-inhoude en -begrippe soms nie inlyn geplaas met
voorstellings van die wiskundekurrikulum nie, en word doelstellings nie bereik nie. Onderwysers se verskillende interpretasies van wiskundehandboekinhoude verskil radikaal
van mekaar en plaas gevolglik groot druk op onderwysers om ʼn keuse te maak wat betref
die gebruik van ʼn wiskundehandboek vir gebruik in die klaskamer.
In die studie is ʼn wiskundehandboekprofiel en ʼn taakontleding tydens aksienavorsing
geformuleer wat onderwysers in staat sal stel om ʼn professionele ontleding te maak vir
gebruik.
As gevolg van die verskeidenheid wiskundehandboeke wat gekeur word vir gebruik in skole
neem onderwysers aan dat hierdie gekeurde wiskundehandboeke op die kurrikulum gerig is.
Gevolglik word wiskundehandboeke slaafs nagevolg sonder om die wiskundekurrikulum te
raadpleeg. Tekortkominge in wiskundehandboeke en die eie interpretasie van wiskundeinhoude
deur onderwysers laat ʼn groot leemte in hul eie inlynwiskunde-onderrig.
Om te voorsien in hierdie behoefte is ʼn assesseringsprofiel en ʼn inlynmetodiek saamgestel om onderwysers in staat te stel om die inlynaanbieding van begrippe en vaardighede te
monitor. / Curriculum and Instructional Studies / D. Ed. (Didaktiek)

A model for empowerment of families with mentally handicapped childrenKgole, Jermina Chuene 11 1900 (has links)
The purpose of this study was to develop an empowerment model for families of mentally handicapped children in Moletši district in Limpopo Province. To achieve this purpose, the study consisted of four steps, namely exploring the meaning of empowerment in the context of families with mentally handicapped children; developing and describing a model for empowerment of such families; formulating guidelines for the implementation of the model, and evaluating the implementation of the model. A qualitative, explorative, descriptive and contextual theory-generative design was used.
The population of the study was all families who had mentally handicapped children in Moletši district of the Polokwane and Aganang municipalities. Semi-structured interviews, assessment guides and case studies were conducted with the families to evaluate the effectiveness of the model and whether the families reached self-efficacy in the care, treatment and rehabilitation of their mentally handicapped children.
Non-probability, purposive sampling was used in order to obtain relevant information from the correct participants. Concepts were identified and analysed, which led to the development of the model for empowerment of families with mentally handicapped children. The model was applied in practice, where the families’ problems were identified and planned for, and the plans were put into action by means of case studies, and monitoring and evaluation was done through observation, interviews, discussion and meetings.The results revealed that the families proved to be independent and reached self-efficacy in the care, treatment and rehabilitation of their mentally handicapped children. The model is a unique contribution to nursing education, research, administration and practice and sets guidelines for a new field in the practice of psychiatric nursing. / Health Studies / D.

Aspects of ancient Near Eastern chronology (c. 1600-700 BC)Furlong, Pierce James January 2007 (has links) (PDF)
The chronology of the Late Bronze and Early Iron Age Near East is currently a topic of intense scholarly debate. The conventional/orthodox chronology for this period has been assembled over the past one-two centuries using information from King-lists, royal annals and administrative documents, primarily those from the Great Kingdoms of Egypt, Assyria and Babylonia. This major enterprise has resulted in what can best be described as an extremely complex but little understood jigsaw puzzle composed of a multiplicity of loosely connected data. I argue in my thesis that this conventional chronology is fundamentally wrong, and that Egyptian New Kingdom (Memphite) dates should be lowered by 200 years to match historical actuality. This chronological adjustment is achieved in two stages: first, the removal of precisely 85 years of absolute Assyrian chronology from between the reigns of Shalmaneser II and Ashur-dan II; and second, the downward displacement of Egyptian Memphite dates relative to LBA Assyrian chronology by a further 115 years. Moreover, I rely upon Kuhnian epistemology to structure this alternate chronology so as to make it methodologically superior to the conventional chronology in terms of historical accuracy, precision, consistency and testability.
