L'enseignement du volley-ball en milieu scolaire: une problématique transpositive
No full textRésumé
Dans le cadre de la présente étude, nous nous sommes fixés comme objectif d’analyser la transposition didactique du volley-ball et d’identifier la praxéologie didactique mise en œuvre par les enseignants au cours de son enseignement en situation réelle de classe. Pour atteindre cet objectif, nous avons analysé les pratiques de quatre enseignants/entraineurs dans leur cycle d’enseignement/apprentissage au volley-ball. Les résultats essentiels issus de nos investigations ont révélé que les contenus enseignés par chacun des sujets investigués sont conformes à ceux définis par les documents au programme. Les transpositions didactiques opérées par ces sujets pour un même contenu sont différentes. Cette diversité de transposition est liée aux rapports personnel et institutionnel à l’objet de savoir (volley-ball) de chacun de ces enseignants/entraîneurs. De même, les savoirs mis à l’étude au cours de ces enseignements/apprentissages relèvent aussi bien du bloc pratico-technique que du bloc technologico-théorique.
Summary
In the setting of this study, our goal is to analyse the didactic transposition of volleyball and to identify the didactic praxeology carried out by teachers during their teaching in real class situation. To reach this goal, we have analysed four teachers / coaches practices in their teaching/learning cycle of volley- ball. The essential results of our investigations have revealed that the contents taught by each of the subjects investigated are in for conformity with those defined by the documents of the syllabus. The didactic transpositions operated by these people for a same content are different. This diversity of transposition is connected with personal and
institutional reports related to the object of knowing (volley- ball) of each of these teachers / coaches. These teachings/learnings are as part of practico-technical block as of technologico-theoretical.

The future of urban schools: integrating community into vertical school architecture
No full textToday we lack a substantial discussion on how educational design
should define our future. As Toronto continues to increase in density, so
has the demand for schools. Condo apartment completions averaged
approximately 19,000 units per year up to 2020, which is in line with levels
from 2014 to 20161 . If all the proposed residential units (active and built)
are completed and registered, the number of registered condominium units
in the City of Toronto will increase by 12% to a total of 210,350 units which
could generate approximately 20,000 new students by 20512
. School
boards are struggling to keep up with demands for space. Traditionally
designed in a horizontal, dispersed fashion, schools are meant to provide the
space to promote learning and growth, relying heavily on outdoor spaces.
However, as the population within the city increases, land becomes scarce.
Fostering a learning environment that is not dependent on the restrictions
of external physical environment becomes an ever-increasing challenge.
This project fuses urban design and architecture together. Urban
design fails when the architecture is forgotten and vice versa. Researching
both the current urban design strategies and the current architectural design
typologies of the Yonge Eglinton area, my goal is to fuse the typologies
together for the future development of the area. With all the development of
the Yonge Eglinton area, an ongoing trend is building vertically. This thesis
examines the current city density and explores the advantages of a newly
imagined mid-town school. The traditional design of a school surrounded
by green, open space and playgrounds may no longer be a reality for areas
of Toronto that are densely populated with unsustainable infrastructure in
existing schools. Therefore, this proposal supports a vertical elementary
school typology with access to a variety of community services in the same
building. The selected services that the mixed use project offers to the
community were purposefully chosen to cultivate meaningful relationships
between the surrounding neighbourhoods, parents, students and
teachers, creating a thoughtful and useful building dedicated to serving
the Yonge and Eglinton community. With this new development model, the
community will be embedded into the school. As part of my site analysis,
the history and the future of the Yonge Eglinton community will be taken
into careful consideration in order to design a site-specific community hub
Experiences of families and survivors following a sudden cardiac arrest: a metasummary
No full textAn uptake of emerging evidence contributes to increasing survival rates following a sudden
cardiac arrest. Life after survival often involves a myriad of altered physical, mental, cognitive,
and social functions for both survivors and their families. The study purpose was to aggregate
published qualitative evidence to yield an understanding of survivors' and family members' life
experiences following cardiac arrest. Using metasummary, 17 international published studies
were selected. The extraction, editing, and abstraction of findings from 230 adult participants
resulted in eight topical categories including: acknowledging life has changed, confronting
mortality, regaining former life, interacting within the family, interacting within the broader
social context, involving healthcare providers, evolving health status, and enacting a new life.
The two themes were seeking wholeness and being connected. Healthcare providers are urged to
prioritize the development and implementation of resourced individualized discharge plans to
promote continuity and comprehensiveness of care for survivors and families.Master of Science in Nursing (MScN
Semi-autonomous computer vision-based rockbreaker
No full textAutomating rockbreaker manipulation improves the safety and performance of mining site operations. The goal of this project is to design and develop a semi-autonomous rockbreaker. This research contributed to both the industrial and scientific aspects of this problem.
For the industrial part, we implemented a complete semi-autonomous rockbreaker’s chain. Our proposed system will solve teleportation challenges. Also, it will fulfill some of the requirements of a fully autonomous rockbreaker. Besides, it can be used for future research toward a final fully autonomous rockbreaker. We proposed a heuristic path planner algorithm that can compete with a trained operator in terms of both speed and accuracy of reaching the target position. For the scientific part, we proposed a camera-based arm tracking algorithm that overcomes the shortcomings of the current non-camera-based approach. Moreover, it decreases both installation and maintenance costs. Furthermore, it is more stable than the current approach as well. Using our industrial product, we suggested a method to automatically generate labelled data to train our camera-based arm tracking method
Signal processing for a three-component transmitting (3CTx) electromagnetic device
Get PDFWhen a three-component transmitter (3CTx) transmits simultaneously from all three
transmitters, the signal measured in a receiver coil will be the sum of the three primary and
secondary fields. In order to interpret the data, it is necessary to separate the signals from each
transmitter. In a numerical experiment utilizing time-domain type sources, a synthesized signal
comprised of the sum of three transmitter signals, a powerline signal and a low-frequency noise
signal was created. Frequency spectra showed that for multiple specific combinations of base
frequencies it is possible for the harmonics to be unique (not overlapping) and hence identifiable.
For these combinations, the transmitter signals can be separated using a stacking filter in the
time-domain. One specific combination is 30 Hz, 32.5 Hz, and 35 Hz for the three transmitters,
when the powerline is operating at 60 Hz. The secondary fields generated by these three base
frequencies were modelled using a wire-loop. Analyzing the response in three off-time and five
on-time windows, it was determined that the maximum differences caused by having three
different base frequencies are predictable and correctable. Thus, building and field testing the
3CTx is practical.Master of Science (MSc) in Geolog
Modelling of an industrial Nickel powder decomposer
No full textThe nickel carbonyl, primarily known as Nickel tetracarbonyl gas, is decomposed when it is
subjected to high temperature at an elevated pressure to produce nickel powder and carbon
monoxide. The nickel powder thermal decomposer process has been used in the industry
for nickel purification for over a hundred years. However, theoretical dynamic modelling on
this process is limited and the few ones are primarily based on empirical models. In this
work, a theoretical and empirical dynamic modelling of nickel carbonyl thermal decomposer
is presented.
Theoretical modelling was carried out on the nickel thermal decomposer process based on
mass and energy conservations, and both steady state and dynamic models were developed
for the process. A steady-state model was proposed to describe the relationship between gas
temperature and nickel carbonyl (Ni(CO)4) decomposition percentage along the reactor. A
partial differential equation (PDE) model was developed to describe the dynamic profiles of
the process variables. Simulations were performed to explore the dynamic effects of process
variables. The results indicate that feed flowrate affects the gas temperature and the dynamics
of temperature gets slower from sections(1-4). The simulated results also show that one
zone wall temperature mainly affects the internal temperature at the same zone with the
impact also seen spread across to other sections. The obtained theoretical models help to
enhance our understanding of the process, provide the needed information for process design,
optimization and improved process control. The model also gave background information
about the important variables for empirical modelling.
Based on the industrial test data, empirical models were proposed for the nickel thermal
decomposer process for the purposes of enhancing process control . The sections(1-4) internal
temperature profiles of the decomposer were modelled as a function of 4 wall temperature input
and input feed flowrate into the decomposer process. The obtained empirical models describe the dynamics of the internal temperature profile. The models show that the feed flowrate
has effect on the internal temperature of the Nickel powder thermal decomposer and its effect
increases as the gas mixture flows through from section 1 to section 4 of the decomposer. The
input feed gas flowrate has negative gains on the internal temperatures of 4 sections. The
wall temperature input has positive gains on the internal temperature of the same section
but its impact spreads across other sections. The obtained empirical models were evaluated
by comparing the model predicted data with industrial measured data and model residuals
were also calculated. The results indicate that the obtained models match the industrial data
reasonably well. The obtained models provide a necessary basis for applying advanced process
control and thereby improving process quality and production efficiencyMaster’s of Applied Science (MASc.) in Natural Resources Engineerin
Turning concussion management on its head: an exploratory model for managing varsity athletes following a sport-related concussion
No full textThe objective of this study was to determine and discuss various relationships between
symptoms, Post-concussion Symptom Score and Symptom Severity Score, exercise prescription,
and RTL as well as RTP times. These relationships were investigated using a combination of
statistical quantitative and qualitative assessments. The study found that some of the symptoms
presented were related to one another and predominantly only presented in clusters. It was also
found that recovery time generally takes longer than previously reported; more than 30 days vs
the previous standard of 14 days until full recovery. Thus, a general guideline with respect to
recovery times was created that can be provided to athletes, coaches, and other stakeholders,
with the intent of removing some of the external pressures that clinicians face to return athletes
to their sport safely and effectivel
Ecotone adaptive dwelling in Ontario: learning from plants
No full textPlants are resilient and beautiful. They can teach us how to live harmoniously with our surrounding
ecosystem and with nature. Plants have developed strategies that allow them to adapt to the everchanging environmental conditions. Unlike buildings, they are dynamic and rely on mutualistic
relationships with the land and other living beings. This thesis looks at the theory of biomimicry and
focuses on adaptive architecture, exploring the design principles and analyzing the criticism of both
approaches in order to learn how we can design a 'living' adaptive dwelling space that creates a dynamic
architectural ecosystem where the users are 'symbiotic' participants, actively adapting to changing
environmental conditions using hands-on, low-tech solutions. The proposed adaptive dwelling, located in
an ecotone region in Eastern Ontario, lives in harmony with the natural cycles and challenges the current
ideals of comfort on a natural site
The geology of the Windfall gold deposit, Québec, Canada
No full textThe Windfall deposit is an advanced-stage exploration gold project owned and operated
by Osisko Mining Inc. and is located in the northeastern portion of the Abitibi greenstone belt,
Québec, Canada. This is the first deposit-scale study and as such aims to provide an
understanding of its geological setting and the evolution with a focus on the origin of gold
mineralization. The study integrates several aspects, including: 1) geological mapping; 2)
characterization of the various host rock lithologies and their alteration; 3) results of new age
dating; and 4) characterization of the different vein types, their mineralogy and chemical and
textural nature of the gold mineralization. The overall conclusion of the study suggests that the
gold deposit formed ca. 2.7 Ga due to a magmatic-hydrothermal fluid exsolved from an
underlying magma now represented by a swarm of felsic dike rocks spatially associated with the
ore body
Observations of environmental interactions with the human organism
No full textThe recording and diffusion of ideas provides future generations of humanity the opportunity to
further the advancement of understanding. This dissertation will begin the investigation of
understanding ‘What influences of the Earth’s environment exist on human behaviour?’ The
phenomena comprising the thesis involve the human organism, environmental stimuli, and
societal customs.
This investigation will consider the large degrees of variability due to the large number of
interactions within the defined local environmental system. Review of research literature has
introduced opportunity for identifying current limitations of the knowledge acquired. Novel
interdisciplinary research is presented, including the relationship between the sun and earth, the
ability correctly identify the human organism from background photon measurements, effects of
population density on disease incidence, and the corresponding relationship between the sunearth interactions and the global behaviour of the human organism.
The presented research accounts for the large degrees of variability between humans by utilizing
global, big data analysis. The implications propose future health and well being awareness on a
planetary scale
