description: Concern is mounting over the increase in prevalence and severity of overweight and obesity in children worldwide. Intrauterine life has been identified as a critical period for the development of overweight or obesity and other related chronic diseases. Prenatal exposure to maternal cigarette smoke (PEMCS) has consistently emerged as an important risk factor for excess weight in the offspring and is a targetable behaviour for prevention strategies. This study examines first the relationship between PEMCS and overweight status of children at 10 years of age and second, whether PEMCS is associated with distinct longitudinal BMI trajectories. Analyses include multivariate and multinomial logistic regression and longitudinal group based modeling methods. PEMCS was found to be a significant risk factor for overweight in children independent of birth weight and catch-up growth. However, PEMCS was not associated with BMI trajectory membership. Our results lend support to the paradigm of in-utero excess weight prevention.

description: Background: Adaptive clinical trials (ACTs) represent an emerging approach to trial design where accumulating data are used to make decisions about future conduct. Adaptations can include comparisons of multiple dose tiers, response-adaptive randomization, sample size re-estimation, and efficacy/futility stopping rules. The objective of this scoping review is to assess stakeholder attitudes, perspectives, and understanding of adaptive trials. Methods: We conducted a review of articles examining stakeholders encompassing the broad medical trial community’s perspectives of adaptive designs (ADs). A computerized search was conducted of four electronic databases with relevant search terms. Following screening of articles, the primary findings of each included article were coded for study design, population studied, purpose, and primary implications. Results: Our team retrieved 167 peer-reviewed titles in total from the database search and 5 additional titles through searching web-based search engines for gray literature. Of those 172 titles, 152 were non-duplicate citations. Of these, 119 were not given full-text reviews, as their titles and abstracts indicated that they did not meet the inclusion criteria. Thirty-three articles were carefully examined for relevance, and of those, 18 were chosen to be part of the analysis; the other 15 were excluded, as they were not relevant upon closer inspection. Perceived advantages to ADs included limiting ineffective treatments and efficiency in answering the research question; −perceived barriers included insufficient sample size for secondary outcomes, challenges of consent, potential for bias, risk of type 1 error, cost and time to adaptively design trials, unclear rationales for using Ads, and, most importantly, a lack of education regarding ADs among stakeholders within the clinical trial community. Perceptions among different types of stakeholders varied from sector to sector, with patient perspectives being noticeably absent from the literature. Conclusion: There are diverse perceptions regarding ADs among stakeholders. Further training, guidelines, and toolkits on the proper use of ADs are needed at all levels to overcome many of these perceived barriers. While education for principal investigators is important, it is also crucial to educate other groups in the community, such as patients, as well as clinicians and staff involved in their daily implementation.

description: There has been increasing recognition of the importance of children's outdoor play and independent mobility for thriving children, neighbourhoods, cities and society, which has led to calls to reverse children's retreat from the street commonplace in many Western nations. We privilege the voices of children aged 10–13 living in three diverse neighbourhoods in an urban centre in Canada to examine the factors that influence children's unsupervised outdoor activities (UOA), such as play, hanging out, and active. A total of 105 children participated in go-along interviews. Analyses revealed two themes: First, ‘feeling safe’ encompassed a sense of social and physical safety, including children's sense of neighbourliness, social dangers, discomfort around traffic, and personal agency to keep themselves safe. Second, having ‘things to do,’ included the affordances that children perceived as important in their neighbourhoods, particularly having other children to play with, diverse amenities and access to nature, and opportunities for challenge and risky play. We outline a conceptual model of children's decision process for UOA that identifies key variables that influence children's engagement in UOA.

description: The Millennium Galaxy Catalogue (MGC; Liske et al. 2003) is designed to provide a comprehensive resource for the study of structure in the Universe on 1–100 kpc scales, i.e. galaxies. Structure in the local Universe on >1 Mpc scales is relatively well understood, thanks to a well developed cosmological theory (ΛCDM), and extensive surveys such as the two-degree Field Galaxy Redshift Survey (2dFGRS; Colless et al. 2001). However, the story on the smaller 1–100 kpc scales is significantly different and structure at this level is not fully understood. This is not surprising as this scale constitutes a regime dominated by non-linear physical behaviour, where mass concentrations have decoupled from the Hubble flow, and where baryon physics becomes critical as the baryons eventually dominate over the dark matter. Numerical models are, as yet, unable to grapple with this regime until such time as the baryon physics can be comprehensively encoded. Instead, models of galaxy formation rely on semianalytic extensions, which in turn are based on empirical data and a few key analytical recipes (see Baugh 2006). It is therefore important to recognise that empirical datasets are currently driving our understanding of galaxy formation, with the semi-analytic models rapidly developing to accommodate new empirical studies.

description: During the Second World War, training was the Canadian Army’s longest sustained activity. Aside from isolated engagements at Hong Kong and Dieppe, the Canadians did not fight in a protracted campaign until the invasion of Sicily in July 1943. The years that Canadian infantry units spent training in the United Kingdom were formative in the history of the Canadian Army. Despite what much of the historical literature has suggested, training succeeded in making the Canadian infantry capable of succeeding in battle against German forces. Canadian infantry training showed a definite progression towards professionalism and away from a pervasive prewar mentality that the infantry was a largely unskilled arm and that training infantrymen did not require special expertise. From 1939 to 1941, Canadian infantry training suffered from problems ranging from equipment shortages to poor senior leadership. In late 1941, the Canadians were introduced to a new method of training called “battle drill,” which broke tactical manoeuvres into simple movements, encouraged initiative among junior leaders, and greatly boosted the men’s morale. The Canadians participated in numerous military exercises of varying sizes that exposed problems with their senior leadership. The replacement of unsuitable officers greatly enhanced the fighting potential of Canadian units and formations. As time went on, infantry training became more rigorous and realistic, and tactical concepts became increasingly sophisticated. By the time of the invasion of Normandy in June 1944, infantry training was intense, suited to units’ assigned tasks, and highly technical, which belied the false prewar assumption that the infantry was an unskilled arm. By the time Canadian divisions entered battle, they were as prepared as they would ever be. The exception to this was the training of the overseas reinforcement units, which reached an acceptable standard only in the last months of the war. This study ultimately represents a substantial contribution to understanding the history of the Canadian Army and its role in the Second World War.

description: Piano teachers believe that dropping out before reaching a moderate mastery of the piano is a common problem among students. This study uses Self-Determination Theory to examine three issues related to the high dropout rate from private piano lessons: whether there are predictors associated with dropout, whether low levels of motivation correlate with dropping out, and the primary reasons invoked for stopping lessons. Using the Survey of Musical Interests, 55 former piano students who quit lessons completed a questionnaire with Likert-scale, multiple choice, and open-ended questions, and their parents also filled out a complementary questionnaire. These participants were compared to 153 students and parents who were still involved with piano lessons. Results showed important predictor differences in parental backgrounds, musical ability, and practice habits, and significant differences between the groups’ autonomous motivation. The main reasons invoked for stopping lessons included lack of practice, preferring other instruments, and loss of interest.

description: In September 2007, a young man called Mike Rennie won the Queensland Aboriginal and Torres Strait Islander Student of the Year award, which recognises outstanding achievements in vocational education. Mike's winning qualification was a Certificate III in Radio Broadcasting, completed through the Brisbane Indigenous Media Association (BIMA). BIMA is the not-for-profit organisation behind the Indigenous radio station 989fm and its Registered Training Organisation, Triple A Training. Mike believes there is a real need for media training in remote Indigenous communities. More intensive programs are required in order to raise digital literacy within communities, skill up local media workers and create culturally appropriate courseware. Vocational training stands for jobs and sustainable industries. In the creative industries training also results in social and cultural outcomes.

description: Étudier les plaisirs féminins dans la littérature française de la Renaissance, c’est d’abord faire le constat d’une pluralité de représentations qui se regroupent autour d’un même enjeu, celui de l’honnêteté. En raison d’une forte tradition misogyne, il est en effet difficile pour une femme de concilier cet impératif social avec le plaisir. Les textes que nous étudions (récit, poésie, littérature d’idées) sont toutefois portés par une dynamique entre voix féminines et voix masculines, qui contribue à faire émerger un discours nouveau sur le plaisir féminin que nous nous proposons d’étudier. La première partie étudie les plaisirs dans l’espace conjugal. Celui-ci fait de la volupté féminine, dans la relation entre époux et dans l’adultère, à la fois une nécessité et une déviance. La deuxième partie s’attache à l’espace social et interroge les plaisirs de cour : les échanges amoureux influencés par l’amour courtois, le néo-platonisme et le pétrarquisme, et les divertissements collectifs, de la danse à la conversation. La troisième partie, consacrée à l’espace de soi, se dégage de la morale sociale dont les deux premières parties sont tributaires pour proposer une réflexion sur le plaisir comme accomplissement de soi dans la maternité, le savoir, la spiritualité et l’écriture.

description: Este artigo aborda a aplicação da teoria dos discursos de Lacan à área de comunicação. Com base em pesquisa bibliográfica, que inclui textos do autor ilustrativos da aplicação proposta, sua intenção é examinar modos de uso dessa ferramenta e o recurso a ela como instrumento de articulação interdisciplinar. Demonstra-se que a teoria dos discursos serve como fator de aproximação e diferenciação, pivô de raciocínio abdutivo, roteiro de evolução histórica, critério de sistematização e método subjacente, e que a interface entre comunicação e psicanálise propiciada pela aplicação dessa teoria envolve a noção de psicanálise em extensão e operações de importação, exportação e contextualização conceituais. Daí se conclui que tal aplicação é útil para pesquisas não apenas em comunicação mas até mesmo em psicanálise, além de contribuir para a compreensão do contexto social mais amplo.

description: The demand of attaining information and the wish to communicating anytime and anywhere has caused numerous innovations in the digital communication world. Today, approximately half of the people on earth somehow use wireless technology which is in every part of our lives. LTE (Long Term Evolution) and WIMAX (Worldwide Interoperability for Microwave Access) standards are the two leading wireless technologies, which support high data rates, multimedia applications, and voice video communications at very high speeds, also called 4G cellular systems in the global market.

These high expectations from wireless technology have revealed multiple antenna techniques which improve the performance and robustness of wireless channels using an array of antennas for both receiving and transmitting. Antenna arrays improve the channel quality by mitigating the effects due to multipath propagation.

In this thesis, better performance of LTE systems with multi antenna techniques is studied. After introducing multi antenna techniques, a wireless channel environment with fading paths is implemented using MATLAB software. The receive diversity techniques considered are maximal ratio combining (MRC) and selection combining (SC) and they are investigated for different number of antenna configurations. Also varying numbers of fading paths are simulated in the thesis. Finally, a comparison between LTE and WIMAX is performed for several fading paths and their performances are evaluated.

description: The urban forest is a green infrastructure system that delivers multiple environmental, economic, social and health services, and functions in cities. Environmental benefits of urban trees are well understood, but no review to date has examined how urban trees affect human health. This review provides a comprehensive summary of existing literature on the health impacts of urban trees that can inform future research, policy, and nature-based public health interventions. A systematic search used keywords representing human health, environmental health, and urban forestry. Following screening and appraisal of several thousand articles, 201 studies were conceptually sorted into a three-part framework. Reducing Harm, representing 41% of studies, includes topics such as air pollution, ultraviolet radiation, heat exposure, and pollen. Restoring Capacities, at 31%, includes attention restoration, mental health, stress reduction, and clinical outcomes. Building Capacities, at 28%, includes topics such as birth outcomes, active living, and weight status. The studies that were reviewed show substantial heterogeneity in purpose and method yet indicate important health outcomes associated with people’s exposure to trees. This review will help inform future research and practice, and demonstrates why urban forest planning and management should strategically promote trees as a social determinant of public health.

description: This article discusses the application of Lacan’s discourse theory in the field of communication. Based on bibliographical research, which includes texts of the author illustrating the proposed application, its purpose is to examine modes of use of this tool and the recourse to it as an instrument of interdisciplinary articulation. It is shown that the discourse theory serves as factor of rapprochement and differentiation, pivot for abductive reasoning, framework for historical evolution, criterion for systematization and underlying method, and that the interface between communication and psychoanalysis brought about by the application of this theory involves the notion of psychoanalysis in extension and operations of conceptual import, export and contextualization. It follows that this application is useful for research not only in communication but even in psychoanalysis, in addition to contributing to the understanding of the broader social context.

description: Obsidian Dome is a 550-650 year old, 1.5 by 1.8 km extrusion of high silica rhyolite situated along the Inyo Craters in eastern California. Field, and observations of drill core, reveals discrete metre-scale thick zones of rhyolitic glass exposed along the margin of Obsidian Dome as well as within its interior. Millimetre-scale flow-banded obsidian, pumice and rhyolite range from planar to chaotically folded, the latter a product of ductile, compressive deformation. Fractures, some of which display en-echelon splitting patterns are a result of brittle failure. Taken together, these features along with others, result from flow during lava dome growth and suggest complex emplacement patterns signified by vesiculation, crystallization and repeated brittle-ductile deformation, owing to episodic crossing of the glass transition. Evidence further shows that gas loss from the system occurred due to explosions, pumice formation and also brecciation of the melt as it episodically crossed the glass transition. Loss of gas by these mechanisms along with the inherent high viscosity of rhyolite melt explains the large amount of glass found on and within Obsidian Dome and other similar rhyolite extrusions in comparison to less silica-rich systems.

Bei der Entwicklung eines entsprechenden Modells war es jedoch der Grundgedanke, bestehende Strukturen und Abläufe so weit wie möglich unverändert zu belassen. Es soll möglichst wenig in die unternehmerische Freiheit der Unternehmen eingegriffen werden, die sich bereits als Wiederverwendungseinrichtung betätigen oder dies zu tun gedenken. Daher werden nur solche Normierungen vorgeschlagen, die als Ergänzung zum bestehenden System minimal notwendig sind. Sollte sich die Tätigkeit als Wiederverwendungseinrichtung dennoch nicht wirtschaftlich ausüben lassen, so ist keine spezielle finanzielle Förderung vorgesehen.

Lithium-ion battery fast charging: understanding the effects of transport properties and thermal heterogeneity on lithium plating
Creators: name: Tomaszewska, Anna Iwona
Publisher: name: Imperial College London
Year: 2023

description: Fast charging of Li-ion batteries is associated with a risk of lithium plating, a process that can lead to rapid capacity fade and safety concerns. The work presented in this thesis aims to improve the understanding of the impact of thermal conditions and cell transport properties on the lithium plating behaviour. The study focuses on two areas: the effects of the temperature and cell type on the performance of charging protocols, and the impacts of through-plane thermal gradients on the severity and distribution of plating. Following a literature review, the modelling and experimental methods are discussed. Through modelling study, it is found that the relative effectiveness of different fast charging protocols at minimising plating depends on the timescales of both solid and electrolyte phase diffusion. When these timescales are low, in power-optimised cells or at high temperatures, protocols that feature high current boost stages may reduce the amount of plating. In the latter part of the work, thermal gradients are found to increase the rate of degradation during fast charging through amplifying non-uniformity in lithium deposition. The deposits are studied through microscopy and quanti ed using titration gas chromatography. The plating morphology is found to affect the associated SEI layer growth and the rate of capacity fade. In colder cells, or in the colder layers of cells cycled under a thermal gradient, more dendritic morphologies and increased SEI growth are observed. In warmer cells, or warmer layers, the deposition is denser and more uniform, with little or no correlation between the amount of deposition and the amount of the SEI. Finally, cathode kinetics are found to influence the plating distribution. These findings highlight the key role of transport properties, affected by the temperature and thermal heterogeneity, in determining the plating behaviour as well as the severity of its consequences.

description: Networks of indigenous irrigating farmers played an influential role in the Cochabamba Water War of 2000 that succeeded in ousting the major water company Bechtel from Bolivia and securing changes to the national legislation to recognize indigenous water rights. In their mobilization against privatization, the irrigators used a narrative grounded in the defense of their water rights and traditional uses and customs or usos y costumbres. Following the Water War, the irrigators effectively organized to have their traditional water rights recognized in the new Irrigation Law no. 2878, which was signed into law in 2004, and the Regulations, which came into effect in 2006. This paper critically examines the impacts of the Irrigation Law on access to water in the heavily farmed region of the Cochabamba Valley. It asks whether the social inequalities amongst farming communities, often exacerbated by usos y costumbres, are being reinforced through the law’s implementation. An analysis of the political processes of institutional change and the power dynamics in the rural water sector reveals that the configuration of power asymmetries formalized in the Irrigation Law maintains unequal access to water resources.

description: Underground mining produces a huge amount of voids and an even larger quantity of mine waste. Overlooking these voids could lead to the possibility of ground subsidence, as well as safety issues during mining operation; while ignoring the waste, could cause environmental pollution and significant suffering. One solution to remedy both (the voids and the waste) is cemented paste backfill (CPB), which is gaining increased recognition in both the mining industry and academic research. Transforming tailings into cemented paste, and transporting this back to underground stopes, not only negates these safety issues to a large degree, but also makes it possible to put waste to good use.However, most studies involving CPB have been conducted at temperatures above 0°C; knowledge of CPB in sub-zero environments is still lacking. For this reason, this thesis investigates the mechanical behaviour of CPB in a the latter type of environment.Uniaxial compressive strength tests were carried out on a series of frozen CPB (FCPB) samples to evaluate the mechanical behaviour (e.g. compressive strengths, geotechnical features, and the stress-strain relationships) of FCPB. It has been discovered in this thesis that FCPB exhibits remarkable strength compared to CPB and, has a great resemblance to frozen soil. Factors which may affect the behaviour of FCPB were thoroughly examined. Binder contents and types were found to be irrelevant; water content, in contrast, plays a dominant role, with an optimum value of around 26% by weight. Sulphate was confirmed to have an adverse effect on the strength of FCPB due to the increasing unfrozen water content and the formation of legible ice lenses. Hydraulic conductivity tests, scanning electron microscope observations, thermal gravimetric analyses, and mercury intrusion porosimetry were also performed as subsidiary experiments to understand the geotechnical features of FCPB. This information will be of significant value for numerous practical applications.

description: Unreinforced masonry construction is considered to be the most vulnerable forms of construction as demonstrated through recent earthquakes. In Canada, many densely populated cities such as (Vancouver, Montreal and Ottawa) have large inventories of seismically vulnerable masonry structures. Although measures have been taken to rehabilitate and increase the seismic resistance of important and historic structures, many existing unreinforced masonry structures have not been retrofitted and remain at risk in the event of a large magnitude earthquake. There is therefore a need to identify buildings at risk and develop tools for assessing the seismic vulnerability of existing unreinforced masonry structures in Canada. This thesis presents results from an ongoing research program which forms part of a multi-disciplinary effort between the University of Ottawa’s Hazard Mitigation and Disaster Management Research Centre and the Geological Survey of Canada (NRCAN) to assess the seismic vulnerability of buildings in dense urban areas such as Ottawa, Ontario. A risk-based seismic assessment tool (CanRisk) has been developed to assess the seismic vulnerability of existing unreinforced masonry and reinforced concrete structures. The seismic risk assessment tool exploits the use of fuzzy logic, a soft computing technique, to capture the vagueness and uncertainty within the evaluation of the performance of a given building. In order to conduct seismic risk assessments, a general building inventory and its spatial distribution and variability is required for earthquake loss estimations. The Urban Rapid Assessment Tool (Urban RAT) is designed for the rapid collection of building data in urban centres. This Geographic Information System (GIS) based assessment tool allows for intense data collection and revolutionizes the traditional sidewalk survey approach for collecting building data. The application of CanRisk and the Urban RAT tool to the City of Ottawa is discussed in the following thesis. Data collection of over 13,000 buildings has been obtained including the seismic risk assessment of 1,465 unreinforced masonry buildings. A case study of selected URM buildings located in the City of Ottawa was conducted using CanRisk. Data obtained from the 2011 Christchurch Earthquake in New Zealand was utilized for verification of the tool.

description: This article discusses the application of Lacan’s discourse theory in the field of communication. Based on bibliographical research, which includes texts of the author illustrating the proposed application, its purpose is to examine modes of use of this tool and the recourse to it as an instrument of interdisciplinary articulation. It is shown that the discourse theory serves as factor of rapprochement and differentiation, pivot for abductive reasoning, framework for historical evolution, criterion for systematization and underlying method, and that the interface between communication and psychoanalysis brought about by the application of this theory involves the notion of psychoanalysis in extension and operations of conceptual import, export and contextualization. It follows that this application is useful for research not only in communication but even in psychoanalysis, in addition to contributing to the understanding of the broader social context.

Subjects: Civic Education
Experience Based Learning

description: This study examines an educational intervention, which attempts to create experiential learning opportunities, to gain an understanding of the effects of teachers’ and students’ development as active democratic citizens. The educational intervention comes in the form of a youth program entitled ‘Day of Information for a Lifetime of Action’ (DILA). The research answers the following question: does an experiential approach to the delivery of the Grade 10 Civics Curriculum such as DILA affect the development of active democratic citizens - as characterized by civic identity, civic engagement, and civic competence? And if so, how does it influence the students' understanding of their role in a democratic society, their self-reported likelihood of future civic engagement and their self-reported ability to be civically effective?

description: The first objective was to test the prospective relationship between need satisfaction and coping. A total of 113 undergraduate students completed a measure of need satisfaction at Time 1 (T1; i.e. a few weeks before the midterm exams) as well as a measure of coping at Time 2 (T2; i.e. a few weeks after the midterm exams). Results indicated that need satisfaction T1 explained unique variance in both dimensions of coping T2, namely task-oriented and disengagement-oriented coping, even after having statistically controlled for gender, Conscientiousness, Neuroticism, and social desirability at T1. The second objective was to examine a model in which need satisfaction and coping predict the amount of progress towards academic goals and, in turn, how coping and goal progress are associated to increases in need satisfaction over the course of a semester. A total of 166 undergraduate students completed a measure of need satisfaction at Time 1 (T1; i.e. a few weeks before the midterm exams) as well as measures of coping, goal progress, and need satisfaction at Time 2 (T2; i.e. a few weeks after the midterm exams). Results from structural equation modeling indicated that coping T2 fully mediated the relationship between need satisfaction T1 and goal progress T2. Results also indicated that goal progress T2 partially mediated the relation between task-oriented coping T2 and need satisfaction T2 as well as between disengagement-oriented coping T2 and need satisfaction T2.

description: In order to succeed, it is imperative that all e-commerce systems include an effective and reliable trust and reputation modeling system. This is particularly true of decentralized e-commerce systems in which autonomous software engage in commercial transactions. Many researchers have sought to overcome the complexities of modeling a subjective, human concept like trust, resulting in several trust and reputation models. While these models each present a unique offering and solution to the problem, several issues persist. Most of the models require direct experience in the e-commerce system in order to make effective trust decisions. This leaves new agents and agents who only casually use the e-commerce system vulnerable. Additionally, the reputation ratings of agents who are relatively new to the system are often indistinguishable from scores for poorly performing agents. Finally, more tactics to defend against agents who exploit the characteristics of the open, distributed system for their own malicious needs are required. To address these issues, a new metric is devised and presented: seniority. Based on agent age and activity level within the e-commerce system, seniority provides a means of judging the credibility of other agents with little or no prior experience in the system. As the results of experimental analysis reveals, employing a reputation model that uses seniority provides considerable value to agents who are new agents, casual buyer agents and all other purchasing agents in the e-commerce system. This new metric therefore offers a significant contribution toward the development of enhanced and new trust and reputation models for deployment in real-world distributed e-commerce environments.
Antecedents and consequences of customer satisfaction with interactive voice response

description: The aim of this study was to empirically test a model of antecedents and consequences of customers' satisfaction with interactive voice response (IVR). IVR is a commonplace selfservice technology, yet it has seldom been the focus of academic research. As customers' frustration with IVR is apparent, understanding how customers evaluate IVR and their subsequent behavioural intentions is important. Findings of a study of Australian Football League members who were users of its IVR system indicated that customer satisfaction resulted when it was easy to use, offered fast service and provided customers with feelings of control. Overall satisfaction with the IVR system was related to customers' intentions to reuse it and their trust in the AFL. Managerial implications of the findings are discussed.

description: The mitigation of blast hazards on critical reinforced concrete structures has become a major concern in regards to the safety of people and the integrity of buildings. Recent terrorist incidents and accidental explosions have demonstrated the need to study the effects of such threats on structures in order to develop effective methods of reducing the overall impact of blast loads. With the arrival of innovative materials such as steel fibre reinforced concrete (SFRC), ultra-high performance fibre reinforced concrete (UHPFRC) and high strength steel reinforcement, research is required in order to successfully adapt these new materials in blast-resistant structures. Hence, the objective of this thesis to conduct an experimental parametric study with the purpose of investigating the implementation of these innovative materials in reinforced concrete slabs and panels. As part of the study, a total of fourteen one-way slab specimens with different combinations of concrete, steel fibres and steel reinforcement are tested under simulated blast loads using the University of Ottawa Shock-Tube Facility. The test program includes three slabs constructed with normal-strength concrete, five slabs constructed with SFRC and six slabs constructed with UHPFRC. Among these specimens, four are reinforced with high-performance steel reinforcement. The specimens are subjected to repeated blast loading with gradually increasing reflected pressure and reflected impulse until failure. The performance of the slabs is studied using various criteria such as failure load and mode, maximum and residual deflections, as well as tensile cracking, spalling and secondary fragmentation control. The behaviour of all specimens is compared in different categories to determine the effects of concrete type, steel reinforcement type, steel fibre content and steel fibre type on blast performance. As part of the analytical study the response of the slab specimens is predicted using dynamic inelastic single-degree-of-freedom (SDOF) analysis. The dynamic analysis is conducted by generating load-deformation resistance functions for the slabs incorporating dynamic material properties.
