A novel approach to assessing road-curve crash severity

Curves are a common feature of road infrastructure; however crashes on road curves are associated with increased risk of injury and fatality to vehicle occupants. Countermeasures require the identification of contributing factors. However, current approaches to identifying contributors use traditional statistical methods and have not used self-reported narrative claim to identify factors related to the driver, vehicle and environment in a systemic way. Text mining of 3434 road-curve crash claim records filed between 1 January 2003 and 31 December 2005 at a major insurer in Queensland, Australia, was undertaken to identify risk levels and contributing factors. Rough set analysis was used on insurance claim narratives to identify significant contributing factors to crashes and their associated severity. New contributing factors unique to curve crashes were identified (e.g., tree, phone, over-steer) in addition to those previously identified via traditional statistical analysis of Police and licensing authority records. Text mining is a novel methodology to improve knowledge related to risk and contributing factors to road-curve crash severity. Future road-curve crash countermeasures should more fully consider the interrelationships between environment, the road, the driver and the vehicle, and education campaigns in particular could highlight the increased risk of crash on road-curves.

Learning from insurance data: Injuries to other road users in motorcyclist at-fault crashes

In multi-vehicle motorcycle crashes, the motorcycle rider is less likely to be at-fault but more commonly severely injured than the other road user. Therefore, not surprisingly, crashes in which motorcycle riders are at-fault and particularly the injuries to the other road users in these crashes have received little research attention. This paper aims to address this gap in the literature by investigating the factors influencing the severity of injury to other road users in motorcyclist-at-fault crashes. Five years of data from Queensland, Australia, were obtained from a database of claims against the compulsory third party (CTP) injury insurance of the at-fault motorcyclists. Analysis of the data using an ordered probit model shows higher injury severity for crashes involving young (under 25) and older (60+) at-fault motorcyclists. Among the not at-fault road users, the young, old, and males were found to be more severely injured than others. Injuries to vehicle occupants were less severe than those to pillions. Crashes that occurred between vehicles traveling in opposite directions resulted in more severe injuries than those involving vehicles traveling in the same direction. While most existing studies have analyzed police reported crash data, this study used CTP insurance data. Comparison of results indicates the potential of using CTP insurance data as an alternative to police reported crash data for gaining a better understanding of risk factors for motorcycle crashes and injury severity.

What does built environment research have to do with risk mitigation, resilience and disaster recovery?

One could argue that the nature of our housing stock is a key determining factor in the ability of our citizens to manage risk, be resilient to various natural and human events, and to recover from these events. Recent research has been examining current challenges posed by our housing stock and exploring potential solutions from a range of perspectives. The aim of this paper is to discuss key findings from recent built environment research in Australia to initiate cross-sectorial discussion and debate about the implications and opportunities for other sectors such as emergency management and insurance. Three recent building research projects are discussed: - Heat waves The impact of heat waves on houses and occupants, and proposed changes to building regulations, air conditioning standards and building design, to reduce risks associated with heat waves. - Net zero energy homes Exploration of the potential benefits of a strategic optimization of building quality, energy and water efficiency, and household or community level distributed energy and water services for disaster management and recovery. - Building information Mapping of the flow of information about residential buildings, and the potential for national or regional building files (in a similar manner to personal medical records) to assist all parties to make more informed decisions that impact on housing sustainability and community resilience. The paper discusses how sustainability, environmental performance and resilience are inter-related, and can be supported by building files. It concludes with a call for increased cross-sectorial collaboration to explore opportunities for a whole-of-systems approach to our built environment that addresses a range of economic and environmental challenges as well as disaster and emergency management.

Electronic Building Passport - Final Report: Project 2 National Energy Efficient Building Project Phase 2

The National Energy Efficient Building Project (NEEBP) Phase One report, published in December 2014, investigated “process issues and systemic failures” in the administration of the energy performance requirements in the National Construction Code. It found that most stakeholders believed that under-compliance with these requirements is widespread across Australia, with similar issues being reported in all states and territories. The report found that many different factors were contributing to this outcome and, as a result, many recommendations were offered that together would be expected to remedy the systemic issues reported. To follow up on this Phase 1 report, three additional projects were commissioned as part of Phase 2 of the overall NEEBP project. This Report deals with the development and piloting of an Electronic Building Passport (EBP) tool – a project undertaken jointly by pitt&sherry and a team at the Queensland University of Technology (QUT) led by Dr Wendy Miller. The other Phase 2 projects cover audits of Class 1 buildings and issues relating to building alterations and additions. The passport concept aims to provide all stakeholders with (controlled) access to the key documentation and information that they need to verify the energy performance of buildings. This trial project deals with residential buildings but in principle could apply to any building type. Nine councils were recruited to help develop and test a pilot electronic building passport tool. The participation of these councils – across all states – enabled an assessment of the extent to which these councils are currently utilising documentation; to track the compliance of residential buildings with the energy performance requirements in the National Construction Code (NCC). Overall we found that none of the participating councils are currently compiling all of the energy performance-related documentation that would demonstrate code compliance. The key reasons for this include: a major lack of clarity on precisely what documentation should be collected; cost and budget pressures; low public/stakeholder demand for the documentation; and a pragmatic judgement that non-compliance with any regulated documentation requirements represents a relatively low risk for them. Some councils reported producing documentation, such as certificates of final completion, only on demand, for example. Only three of the nine council participants reported regularly conducting compliance assessments or audits utilising this documentation and/or inspections. Overall we formed the view that documentation and information tracking processes operating within the building standards and compliance system are not working to assure compliance with the Code’s energy performance requirements. In other words the Code, and its implementation under state and territory regulatory processes, is falling short as a ‘quality assurance’ system for consumers. As a result it is likely that the new housing stock is under-performing relative to policy expectations, consuming unnecessary amounts of energy, imposing unnecessarily high energy bills on occupants, and generating unnecessary greenhouse gas emissions. At the same time, Councils noted that the demand for documentation relating to building energy performance was low. All the participant councils in the EBP pilot agreed that documentation and information processes need to work more effectively if the potential regulatory and market drivers towards energy efficient homes are to be harnessed. These findings are fully consistent with the Phase 1 NEEBP report. It was also agreed that an EBP system could potentially play an important role in improving documentation and information processes. However, only one of the participant councils indicated that they might adopt such a system on a voluntary basis. The majority felt that such a system would only be taken up if it were: - A nationally agreed system, imposed as a mandatory requirement under state or national regulation; - Capable of being used by multiple parties including councils, private certifiers, building regulators, builders and energy assessors in particular; and - Fully integrated into their existing document management systems, or at least seamlessly compatible rather than a separate, unlinked tool. Further, we note that the value of an EBP in capturing statistical information relating to the energy performance of buildings would be much greater if an EBP were adopted on a nationally consistent basis. Councils were clear that a key impediment to the take up of an EBP system is that they are facing very considerable budget and staffing challenges. They report that they are often unable to meet all community demands from the resources available to them. Therefore they are unlikely to provide resources to support the roll out of an EBP system on a voluntary basis. Overall, we conclude from this pilot that the public good would be well served if the Australian, state and territory governments continued to develop and implement an Electronic Building Passport system in a cost-efficient and effective manner. This development should occur with detailed input from building regulators, the Australian Building Codes Board (ABCB), councils and private certifiers in the first instance. This report provides a suite of recommendations (Section 7.2) designed to advance the development and guide the implementation of a national EBP system.

Reducing luminance contrast on the window wall and users’ interventions in an office room

High luminance contrast between windows and surrounding surfaces could cause discomfort glare, which could reduce office workers’ productivity. It might also increase energy usage of buildings due to occupants’ interventions in lighting conditions to improve indoor visual quality. It is presumed that increasing the luminance of the areas surrounding the windows using a supplementary system, such Light Emitting Diodes (LEDs), could reduce discomfort glare. This paper reports on the results of a pilot study in a conventional office in Brisbane, Australia. The outcomes of this study indicated that a supplementary LED system could reduce the luminance contrast on the window wall from values in the order of 24:1 to 12:1. The results suggest that this reduction could significantly reduce discomfort glare from windows, as well as diminishing the likelihood of users’ intention to turn on the ceiling lights and/ or to move the blind down.

Tavallisuudesta tyylikkyyteen? : Sukupuoli ja maku kodinmuutosohjelmissa

The study focuses on the Finnish home makeover shows Inno (2004 , Nelonen) and Kodin kääntöpiiri (2001 2005; YLE TV2) and their episodes broadcast in spring 2004. The research material also includes the websites of both shows and messages concerning Inno from an online discussion forum. As people decorate their homes and reflect on them, they engage in negotiations of taste and in the construction of the ideal self. The main question of the study is: how are representations of the gendered self produced in home makeover shows? The broader theoretical and methodological context of the study is based on intersectionality, or simultaneous study of different identity categories. In this study, the main focus is on the intersections of gender, class and sexuality. Hence, the secondary research question is: how do ways of doing gender intersect with producing the ideas of class and sexuality in the representations of home makeover shows? The theoretical framework of the study combines Judith Butler s theory of gender performativity and Pierre Bourdieu s theory of taste. The analysis is founded upon a close reading focusing on the details and ambiguous meanings contained in the televisual representation. Home makeover shows are explored as a part of contemporary television culture, which is characterised by a significant increase in the number of both television channels and global television formats, as well as the hybridisation of programme types. Researchers on lifestyle television have paid attention to male designers and their ability to reconstruct meanings related to domesticity and home decoration as feminine spheres. The dissertation contributes to this discussion by analysing the representations of the male interior decorator in Inno and the four female interior decorators in Kodin kääntöpiiri. The focus is on the professional self and how it is both gendered and defined as an arbiter of taste. The programme concepts produce the impression that the makeover homes and their occupants are ordinary . The manufactured sense of ordinariness often conceals differences between the participants. One argument of the study is that the ordinariness of participants on lifestyle television should not be taken for granted without further reflection on the implications of labeling something as ordinary. Updating of interior decoration in home makeover shows can be interpreted as an area of doing gender that requires deliberation, effort, expert knowledge and a sufficient budget. The ideal lay decorator is portrayed as culturally omnivorous, brave and receptive to new ideas. The ability to reflect on ways of representing masculinity and femininity through decoration is also implied. In home makeover shows, greater self-awareness regarding the ways in which gender is produced does not lead to repeating gender differently. The idea of normative heterosexuality is in a hegemonic position in the representations of the participants. In Inno and Kodin kääntöpiiri questions of class are not made explicit. However, the idea of class is produced indirectly e.g. by describing the apartments and houses of the participants, by discussing their hobbies or interest in cultural products. In Inno, home decoration is primarily depicted as an individualistic consumer choice, while in Kodin kääntöpiiri it is often defined as a way to strengthen the ties of nuclear families. In Kodin kääntöpiiri, the ethos of familism is combined with pleasures gained from consumption and DIY activities. As a whole, the multidisciplinary study indicates a great number of differences between the two shows.

Physiological and subjective thermal response from Indians

A controlled laboratory experiment was carried out on forty Indian male college students for evaluating the effect of indoor thermal environment on occupants' response and thermal comfort. During experiment, indoor temperature varied from 21 degrees C to 33 degrees C, and the variables like relative humidity, airflow, air temperature and radiant temperature were recorded along with skin (T-sk) and oral temperature (T-core) from the subjects. From T-sk and T-c, body temperature (T-b) was evaluated. Subjective Thermal Sensation Vote (TSV) was recorded using ASHRAE 7-point scale. In PMV model, Fanger's T-sk equation was used to accommodate adaptive response. Stepwise regression analysis result showed T-b was better predictor of TSV than T-sk and T-core. Regional skin temperature response, lower sweat threshold temperature with no dipping sweat and higher cutaneous sweating threshold temperature were observed as thermal adaptive responses. Using PMV model, thermal comfort zone was evaluated as (22.46-25.41) degrees C with neutral temperature of 23.91 degrees C, whereas using TSV response, wider comfort zone was estimated as (23.25-2632) degrees C with neutral temperature at 24.83 degrees C. It was observed that PMV-model overestimated the actual thermal response. Interestingly, these subjects were found to be less sensitive to hot but more sensitive to cold. A new TSV-PPD relation (PPDnew) was obtained with an asymmetric distribution of hot-cold thermal sensation response in Indians. (C) 2013 Elsevier Ltd. All rights reserved.

Divvying up an incubator: How parasitic and mutualistic fig wasps use space within their nursery microcosm

Differential occupancy of space can lead to species coexistence. The fig-fig wasp pollination system hosts species-specific pollinating and parasitic wasps that develop within galls in a nursery comprising a closed inflorescence, the syconium. This microcosm affords excellent opportunities for investigating spatial partitioning since it harbours a closed community in which all wasp species are dependent on securing safe sites inside the syconium for their developing offspring while differing in life history, egg deposition strategies and oviposition times relative to nursery development. We determined ontogenetic changes in oviposition sites available to the seven-member fig wasp community of Ficus racemosa comprising pollinators, gallers and parasitoids. We used species distribution models (SDMs) for the first time at a microcosm scale to predict patterns of spatial occurrence of nursery occupants. SDMs gave high true-positive and low false-positive site occupancy rates for most occupants indicating species specificity in oviposition sites. The nursery microcosm itself changed with syconium development and sequential egg-laying by different wasp species. The number of sites occupied by offspring of the different wasp species was negatively related to the risk of syconium abortion by the plant host following oviposition. Since unpollinated syconia are usually aborted, parasitic wasps ovipositing into nurseries at the same time as the pollinator targeted many sites, suggesting response to lower risk of syconium abortion owing to reduced risk of pollination failure compared to those species ovipositing before pollination. Wasp life history and oviposition time relative to nursery development contributed to the co-existence of nursery occupants.

PMV model is insufficient to capture subjective thermal response from Indians

A controlled laboratory experiment was carried out on forty Indian male college students for evaluating the effect of indoor thermal environment on occupants' response and thermal comfort. During experiment, indoor temperature varied from 21 degrees C to 33 degrees C, and the variables like relative humidity, airflow, air temperature and radiant temperature were recorded along with subject's physiological parameters (skin (T-sk) and oral temperature (T-c)) and subjective thermal sensation responses (TSV). From T-sk and T-c, body temperature (T-b) was evaluated. Subjective Thermal Sensation Vote (TSV) was recorded using ASHRAE 7-point scale. In PMV model, Fanger's T-sk equation was used to accommodate adaptive response. Step-wise regression analysis result showed T-b was better predictor of TSV than T-sk and T-c. Regional skin temperature response, suppressed sweating without dipping, lower sweating threshold temperature and higher cutaneous threshold for sweating were observed as thermal adaptive responses. These adaptive responses cannot be considered in PMV model. To incorporate subjective adaptive response, mean skin temperature (T-sk) is considered in dry heat loss calculation. Along with these, PMV-model and other two methodologies are adopted to calculate PMV values and results are compared. However, recent literature is limited to measure the sweat rate in Indians and consideration of constant Ersw in PMV model needs to be corrected. Using measured T-sk in PMV model (Method(1)), thermal comfort zone corresponding to 0.5 <= PMV <= 0.5 was evaluated as (22.46-25.41) degrees C with neutral temperature of 23.91 degrees C, similarly while using TSV response, wider comfort zone was estimated as (23.25-26.32) degrees C with neutral temperature at 24.83 degrees C, which was further increased to with TSV-PPDnew, relation. It was observed that PMV-model overestimated the actual thermal response. Interestingly, these subjects were found to be less sensitive to hot but more sensitive to cold. A new TSV-PPD relation (PPDnew) was obtained from the population distribution of TSV response with an asymmetric distribution of hot-cold thermal sensation response from Indians. The calculations of human thermal stress according to steady state energy balance models used on PMV model seem to be inadequate to evaluate human thermal sensation of Indians. Relevance to industry: The purpose of this paper is to estimate thermal comfort zone and optimum temperature for Indians. It also highlights that PMV model seems to be inadequate to evaluate subjective thermal perception in Indians. These results can be used in feedback control of HVAC systems in residential and industrial buildings. (C) 2014 Elsevier B.V. All rights reserved.

Assessing impact of material transition and thermal comfort models on embodied and operational energy in vernacular dwellings (India)

Vernacular dwellings are well-suited climate-responsive designs that adopt local materials and skills to support comfortable indoor environments in response to local climatic conditions. These naturally-ventilated passive dwellings have enabled civilizations to sustain even in extreme climatic conditions. The design and physiological resilience of the inhabitants have coevolved to be attuned to local climatic and environmental conditions. Such adaptations have perplexed modern theories in human thermal-comfort that have evolved in the era of electricity and air-conditioned buildings. Vernacular local building elements like rubble walls and mud roofs are given way to burnt brick walls and reinforced cement concrete tin roofs. Over 60% of Indian population is rural, and implications of such transitions on thermal comfort and energy in buildings are crucial to understand. Types of energy use associated with a buildings life cycle include its embodied energy, operational and maintenance energy, demolition and disposal energy. Embodied Energy (EE) represents total energy consumption for construction of building, i.e., embodied energy of building materials, material transportation energy and building construction energy. Embodied energy of building materials forms major contribution to embodied energy in buildings. Operational energy (OE) in buildings mainly contributed by space conditioning and lighting requirements, depends on the climatic conditions of the region and comfort requirements of the building occupants. Less energy intensive natural materials are used for traditional buildings and the EE of traditional buildings is low. Transition in use of materials causes significant impact on embodied energy of vernacular dwellings. Use of manufactured, energy intensive materials like brick, cement, steel, glass etc. contributes to high embodied energy in these dwellings. This paper studies the increase in EE of the dwelling attributed to change in wall materials. Climatic location significantly influences operational energy in dwellings. Buildings located in regions experiencing extreme climatic conditions would require more operational energy to satisfy the heating and cooling energy demands throughout the year. Traditional buildings adopt passive techniques or non-mechanical methods for space conditioning to overcome the vagaries of extreme climatic variations and hence less operational energy. This study assesses operational energy in traditional dwelling with regard to change in wall material and climatic location. OE in the dwellings has been assessed for hot-dry, warm humid and moderate climatic zones. Choice of thermal comfort models is yet another factor which greatly influences operational energy assessment in buildings. The paper adopts two popular thermal-comfort models, viz., ASHRAE comfort standards and TSI by Sharma and Ali to investigate thermal comfort aspects and impact of these comfort models on OE assessment in traditional dwellings. A naturally ventilated vernacular dwelling in Sugganahalli, a village close to Bangalore (India), set in warm - humid climate is considered for present investigations on impact of transition in building materials, change in climatic location and choice of thermal comfort models on energy in buildings. The study includes a rigorous real time monitoring of the thermal performance of the dwelling. Dynamic simulation models validated by measured data have also been adopted to determine the impact of the transition from vernacular to modern material-configurations. Results of the study and appraisal for appropriate thermal comfort standards for computing operational energy has been presented and discussed in this paper. (c) 2014 K.I. Praseeda.

Avaliação de carbonilas na atmosfera interior e exterior de salas de aula de escolas públicas

Compostos carbonílicos representam uma das principais classes de poluentes atmosféricos e são frequentemente reportados em estudos de poluição atmosférica de interiores. São emitidos para a atmosfera a partir de uma variedade de fontes naturais e antropogênicas. Em projeto empreendido em 2011 pela Secretaria de Estado de Educação do Estado do Rio de Janeiro,foi implementada a climatização em todas as salas de aula de todas as escolas da rede pública estadual. A escala de exposição de ocupantes à climatização, em salas de aula, não apresenta precedentes em nosso estado e representa uma tendência de todo o país. Como é um projeto recente, não há dados a respeito da qualidade do ar interior nesses ambientes e, portanto, das consequências na saúde dos ocupantes. Os procedimentos foram baseados na metodologia TO-11A da U.S.EPA. A técnica de amostragem foi por via seca com reação química, empregando-se cartuchos de sílica revestidos de octadecil (SiO2-C18) impregnados com 2,4-dinitrofenilhidrazina. As carbonilas foram analisados através de Cromatografia Líquida de Alta Eficiência com detecção por UV. Foram encontradas concentrações de formaldeído na faixa de 3,59 a 26,62 μg m-3 (interior) e 0,74 a 23,47 μg m-3 (exterior), acetaldeído na faixa de 0,19 a 259,47 μg m-3 (interior) e 1,19 a 127,51 μg m-3 (exterior), acetona+acroleína na faixa de 0,00 a 48,45 μg m-3 (interior) e 0,00 a 37,00 μg m-3 (exterior). Os valores encontrados geralmente não ultrapassaram os limites determinados por organismos internacionais

A posse do art. 1276 do CC como forma de aquisição da propriedade imóvel

De inegável relevância na vida humana, a posse se configura como um dos temas mais controvertidos no âmbito do Direito Civil. Em todos os seus contornos e características, incluindo sua natureza jurídica, terminologia, efeitos e classificações, observamos um debate acirrado e polêmico a seu respeito, o que demonstra o firme interesse dos estudiosos sobre a possessio através dos séculos. Ademais, compete ao aplicador do Direito compreender o fenômeno possessório a partir das premissas e valores constitucionais fundamentais, em especial o princípio da dignidade da pessoa humana, levando em consideração as mutações sociais e a realidade dos fatos, para que seja possível extrair do ordenamento caminhos efetivos à concretização de uma sociedade justa e solidária, a fim de erradicar a pobreza e diminuir as desigualdades sociais. Neste contexto, de forma prospectiva e adequando os conceitos civilistas à Carta da República, defendemos a aplicação do artigo 1276 do Código Civil também em benefício do ocupante qualificado de imóvel abandonado, de modo a consolidar o domínio em seu favor no mesmo triênio conferido à Administração Pública, garantindo-se então aos menos favorecidos o legítimo acesso à moradia e ao trabalho. Na medida em que o ser humano se constitui no foco de atenção, preocupação e proteção do ordenamento jurídico acreditamos que as exegeses normativas devem concretizar o disposto no artigo 1, inciso III, da Constituição da República, razão pela qual a posse de outrem exercida ininterruptamente sobre bem abandonado merece funcionar como forma de aquisição originária da propriedade imóvel privada no lapso de tempo estatuído no artigo 1276 do Código Civil.

A regularização fundiária e o registro de imóveis

Este trabalho tem por finalidade apresentar um estudo sobre as contribuições do serviço de registro imobiliário, com destaque em procedimentos de regularização fundiária de imóveis urbanos. Não raras vezes, empreendedores, administradores públicos, juízes, sociedade deparam-se com situações em que há a necessidade de titulação da terra como mecanismo de formalização da propriedade, oportunidade em que são exigidos os requisitos estabelecidos na legislação de regência. A adoção em caráter estrito das regras estabelecidas, em contraposição às peculiaridades e ao desregramento de assentamentos informais, importaria em eterna manutenção dos mesmos à margem da lei. Há, assim, de se criar mecanismos de consenso e soluções de compromisso, em que poder público, registrador imobiliário, operadores do direito e a própria comunidade envolvam-se no sentido de colmatar uma solução intermediária. Solução esta que, sem perder a necessária segurança jurídica dos registros públicos, possibilite a adoção de mecanismos que facilitem o acesso dos ocupantes à titulação da terra em que vivem. O título de propriedade representa mais do que mero papel. Traduz o poder de direito sobre determinado terreno, alçando-o da condição de um capital morto para elemento ativo em um mercado cada dia mais globalizado. Nesta esteira, arregimenta economicamente não apenas a população diretamente envolvida, quanto também possibilita, através da inserção dos imóveis regularizados no mercado, um aproveitamento e um incremento econômico catalisador de transformações econômico-sociais. Novos direitos, novos bens em garantia, novas condições de crédito, renovada segurança jurídica, enfim, novas oportunidades são desdobradas aos detentores, que agora podem investir sem o receio da precariedade decorrente de mera situação de posse. Estuda-se, assim, neste trabalho a importante atuação do registrador imobiliário e as vantagens decorrentes do processo de regularização fundiária, como um processo a ser estimulado e incrementado, concretizador de cidadania e efetivador dos direitos fundamentais de propriedade (art 5 CF/88) e de moradia (art. 6 da CF/88).

Automated Detection of Exposed Reinforcement in Post-Earthquake Safety and Structural Evaluations

Post-earthquake structural safety evaluations are currently performed manually by a team of certified inspectors and/or structural engineers. This process is time-consuming and costly, keeping owners and occupants from returning to their businesses and homes. Automating these evaluations would enable faster, and potentially more consistent, relief and response processes. In order to do this, the detection of exposed reinforcing steel is of utmost significance. This paper presents a novel method of detecting exposed reinforcement in concrete columns for the purpose of advancing practices of structural and safety evaluation of buildings after earthquakes. Under this method, the binary image of the reinforcing area is first isolated using a state-of-the-art adaptive thresholding technique. Next, the ribbed regions of the reinforcement are detected by way of binary template matching. Finally, vertical and horizontal profiling are applied to the processed image in order to filter out any superfluous pixels and take into consideration the size of reinforcement bars in relation to that of the structural element within which they reside. The final result is the combined binary image disclosing only the regions containing rebar overlaid on top of the original image. The method is tested on a set of images from the January 2010 earthquake in Haiti. Preliminary test results convey that most exposed reinforcement could be properly detected in images of moderately-to-severely damaged concrete columns.
