A key issue in the design of tyres is their capability to sustain intense impact loads. Hence, the development of a reliable experimental data basis is important, against which numerical models can be compared. Experimental data on tyre impact in the open literature is somewhat rare. In this article, a specially design rig was developed for tyre impact tests. It holds the test piece in a given position, allowing a drop mass with a round indenter to hit pressurised tyres with different impact energies. A high-speed camera and a laser velocimeter were used to track the impact event. From the laser measurement it was possible to obtain the impact force and the local indentation. A finite element study was then conducted using material properties from the open literature. By comparing the experimental measurements with the numerical results, it became evident that the model was capable of predicting the major features of the impact of a mass on a tyre. This model is therefore of value for the assessment of the performance of a tyre in extreme cases of mass impact. (C) 2009 Elsevier Ltd. All rights reserved.

This book reviews quantitative methods and models of impact evaluation. The formal literature on impact evaluation methods and practices is large, with a few useful overviews. Yet there is a need to put the theory into practice in a hands-on fashion for practitioners. This book also details challenges and goals in other realms of evaluation, including monitoring and evaluation (M&E), operational evaluation, and mixed-methods approaches combining quantitative and qualitative analyses. This book is organized as follows. Chapter two reviews the basic issues pertaining to an evaluation of an intervention to reach certain targets and goals. It distinguishes impact evaluation from related concepts such as M&E, operational evaluation, qualitative versus quantitative evaluation, and ex-ante versus ex post impact evaluation. Chapter three focuses on the experimental design of an impact evaluation, discussing its strengths and shortcomings. Various non-experimental methods exist as well, each of which are discussed in turn through chapters four to seven. Chapter four examines matching methods...

Measuring the poverty and distributional impact of the global crisis for developing countries is not easy, given the multiple channels of impact and the limited availability of real-time data. Commonly-used approaches are of limited use in addressing questions like who are being affected by the crisis and by how much, and who are vulnerable to falling into poverty if the crisis deepens? This paper develops a simple micro-simulation method, modifying models from existing economic literature, to measure the poverty and distributional impact of macroeconomic shocks by linking macro projections with pre-crisis household data. The approach is then applied to Bangladesh to assess the potential impact of the slowdown on poverty and income distribution across different groups and regions. A validation exercise using past data from Bangladesh finds that the model generates projections that compare well with actual estimates from household data. The results can inform the design of crisis monitoring tools and policies in Bangladesh...

Concerns have been raised about the impact of rising food prices worldwide on the poor. To assess the (short term) impact of rising food prices in any particular country it is necessary to look at both the impact on food producers (who benefit from an increase in prices) and food consumers (who loose out when the price increases), with a focus on poor producers and consumers. In Ghana, the impact of a change in the price of rice is not ambiguous because a large share of the rice consumed is imported, so that the negative impact for consumers is much larger than the positive impact for producers. For maize by contrast, the impact is ambiguous since much of the consumption is locally produced. Using a recent and comprehensive household survey, this paper provides an assessment of the potential impact of higher food prices on the poor in Ghana using both simple statistical analysis and non-parametric methods. The paper finds that rising food prices for rice, maize, and other cereals would together lead to an increase in poverty...

To assess the (short term) impact of rising food prices in any particular country it is necessary to look at both the impact on food producers (who benefit from an increase in prices) and food consumers (who loose out when the price increases), with a focus on poor producers and consumers. In Mali the impact of a change in the price of rice is not ambiguous because about half of the rice consumed in the country is imported, so that the negative impact for consumers is much larger than the positive impact for producers. By contrast, for millet and sorghum, as well as corn, the impact is more ambiguous since much of the consumption is locally produced. Using a recent and comprehensive household survey, this paper provides an assessment of the potential impact of higher food prices on the poor in Mali using both simple statistical analysis and non-parametric methods.

Very little is known about the actual impact of projects on the poor. Many are reluctant to carry out impact evaluations because they are deemed expensive, time consuming, and technically complex, and because the findings can be politically sensitive. Yet a rigorous evaluation can be powerful in assessing the appropriateness and effectiveness of programs. Evaluating impact is particularly critical in developing where resources are scarce and every dollar spent should aim to maximize its impact on poverty reduction. This handbook seeks to provide project managers and policy analysts with the tools needed for evaluating project impact. It is aimed at readers with a general knowledge of statistics. Chapter 1 presents an overview of concepts and methods, Chapter 2 discusses key steps and related issues to consider in implementation, Chapter 3 illustrates various analytical techniques through a case study, and Chapter 4 includes a discussion of lessons that have been reviewed for this handbook. The case studies, included in Annex I...

Environmentally conscious construction has received a significant amount of research attention during the last decades. Even though construction literature is rich in studies that emphasize the importance of environmental impact during the construction phase, most of the previous studies failed to combine environmental analysis with other project performance criteria in construction. This is mainly because most of the studies have overlooked the multi-objective nature of construction projects. In order to achieve environmentally conscious construction, multi-objectives and their relationships need to be successfully analyzed in the complex construction environment. The complex construction system is composed of changing project conditions that have an impact on the relationship between time, cost and environmental impact (TCEI) of construction operations. Yet, this impact is still unknown by construction professionals. Studying this impact is vital to fulfill multiple project objectives and achieve environmentally conscious construction. This research proposes an analytical framework to analyze the impact of changing project conditions on the relationship of TCEI. This study includes green house gas (GHG) emissions as an environmental impact category. The methodology utilizes multi-agent systems...

OBJECTIVE: Tests are routinely conducted where instrumented headforms are projected at the fronts of cars to assess pedestrian safety. Better information would be obtained by accounting for performance over the range of expected impact conditions in the field. Moreover, methods will be required to integrate the assessment of secondary safety performance with primary safety systems that reduce the speeds of impacts. Thus, we discuss how to estimate performance over a range of impact conditions from performance in one test and how this information can be combined with information on the probability of different impact speeds to provide a balanced assessment of pedestrian safety. METHOD: Theoretical consideration is given to 2 distinct aspects to impact safety performance: the test impact severity (measured by the head injury criterion, HIC) at a speed at which a structure does not bottom out and the speed at which bottoming out occurs. Further considerations are given to an injury risk function, the distribution of impact speeds likely in the field, and the effect of primary safety systems on impact speeds. These are used to calculate curves that estimate injuriousness for combinations of test HIC, bottoming out speed, and alternative distributions of impact speeds. RESULTS: The injuriousness of a structure that may be struck by the head of a pedestrian depends not only on the result of the impact test but also the bottoming out speed and the distribution of impact speeds. Example calculations indicate that the relationship between the test HIC and injuriousness extends over a larger range than is presently used by the European New Car Assessment Programme (Euro NCAP)...

The modeling and analysis of structures using frequency-domain methods simplify the procedure of the modeling and analysis and provides better understanding of the response of the structures. There are different applications in frequency-domain structural modeling and analysis such as modeling and analysis in impact engineering, wave propagation in structures, and micro-resonators. The identification of the impact force and the impact location in structures are important for monitoring the condition of the structures and also for the design of the future structures. The complexity and nonlinearity of the impact incident makes it impractical to measure the impact force directly. In this study, a new method that uses the spectral finite element method (SFEM) is introduced in order to identify and locate the applied impact force. Using SFEM facilitates for the successfully identification of the high frequency content in the impact forces. Also, using SFEM allows for the identification of the impact force independent of the location of the impact force. The impact force identification and localization method is verified by experimental results. For designing and analyzing micro-resonators, it is required to do the frequency-analysis of these structures which provide the frequency characteristics and the frequency-response of the structures. In this study...

ABSTRACT Hypervelocity impact studies of carbon nanotubes and fiber-reinforced polymer nanocomposites by Suman Khatiwada This dissertation studies the hypervelocity impact characteristics of carbon nanotubes (CNTs), and investigates the use of CNTs as reinforcements in ultra-high molecular weight polyethylene (UHMWPE) fiber composites for hypervelocity impact shielding applications. The first part of this dissertation is aimed at developing an understanding of the hypervelocity impact response of CNTs – at the nanotube level. Impact experiments are designed with CNTs as projectiles to impact and crater aluminum plates. The results show that carbon nanotubes are resistant to the high-energy shock pressures and the ultra-high strain loading during hypervelocity impacts. Under our experimental conditions, single-walled carbon nanotubes survive impacts up to 4.07 km/s, but transform to graphitic ribbons and nanodiamonds at higher impact velocities. The nanodiamonds are metastable and transform to onion-like nanocarbon over time. Double-walled carbon nanotubes retain their form and structure even at impacts over 7 km/s. Higher hypervelocity impact resistance of DWCNTs could be attributed to the absorption of additional energy due to relative motion between the layers in the transverse direction of these coaxial nanotubes. The second part of this dissertation researches the effect of reinforcement of carbon nanotubes and their buckypapers on the hypervelocity impact shielding properties of UHMWPE-fiber composites arranged in a Whipple Shield configuration (a shield design used for the protection of the international space station from hypervelocity impacts by orbital debris). Composite laminates were prepared via compression molding and nanotube buckypapers via vacuum filtration. Dispersed nanotubes were introduced to the composite laminates via direct spraying onto the fabric prior to composite processing. The experimental results show that nanotubes dispersed in polymer matrix do not affect the hypervelocity impact resistance of the composite system. Nanotube buckypapers...

This report evaluates the requirements for an assessment of climate change impacts on agriculture to guide policy makers on investment priorities and phasing. Because agriculture is vital for national food security and is a strong contributor to Brazil's GDP growth, there is growing concern that Brazilian agriculture is increasingly vulnerable to climate variability and change. To meet national development, food security, climate adaptation and mitigation, and trade goals over the next several decades, Brazil will need to significantly increase per area productivity of food and pasture systems while simultaneously reducing deforestation, rehabilitating millions of hectares of degraded land, and adapting to climate change. There is inadequate data to accurately model projected climate challenges facing Brazil. The report concludes that key integrated and linked interventions are needed in the short term to significantly improve currently available assessments of climate change impact on Brazilian agriculture and to guide policy makers with the priorities and phasing of needed investments.

Purpose Land use in dry lands can result in a final stage where land is completely depleted or entirely degraded causing the desertification phenomenon. The first part (part 1) of this series of two articles proposed a methodology to include desertification in life cycle assessment (LCA). A set of variables to be measured in the life cycle inventory, characterization factors, and an impact assessment method for the life cycle impact assessment phase were proposed. This second part (part 2) aims at showing the application of the model proposed in part 1 on two case studies of agricultural activities. Methods The impact model proposed is applied to plots of land devoted to agricultural activities in two countries: Argentina and Spain. In the agricultural plots of Spain (1SP to 9SP), two crops were analyzed: winter wheat (Triticum aestivum) and rapeseed (RS, Brassica napus). Two crops were considered in the Argentinean case study: rapeseed (RS, B. napus) and digit grass (Digitaria eriantha) (10AR to 17AR). A bare soil state is considered in both countries as a reference state. Both case studies consider only the agricultural stage in the inventory of a complete life cycle assessment study. Both also consider only one impact category in life cycle environmental assessment: desertification impact due to land occupation. Results and discussion On the basis of the obtained results...

Contribution presented at the 39th Annual Meeting of the Division for Planetary Sciences of the American Astronomical Association (DPS 2007), October 7-12, 2007 Orlando, Florida.; When Deep Impact fired its projectile into the nucleus of comet 9P/Tempel 1, a cloud made of dust and icy grains was ejected from the impact crater. The dust was subsequently accelerated by gas drag. About a week after the impact event, the dust cloud has dispersed due to its expansion and the force exerted by solar radiation pressure. The light curve of the dust cloud contains information about its formation and evolution: the time scale of the production of impact created material can be derived from the time scale of the brightness increase. The velocity distribution of the cloud is indicative of acceleration processes in the inner coma of the comet. Finally, the abundance of large dust particles created by the impact can be estimated from the brightness of the cloud several days after the impact when small particles have been pushed away by radiation pressure.; Here we analyze data obtained by the Narrow Angle Camera (NAC) of OSIRIS onboard the ESA spacecraft Rosetta to derive the velocity distribution of the dust cloud from an inversion of its light curve. OSIRIS observed comet Tempel 1 near-continuously for more than two weeks around the impact. A model of the expansion of the ejecta is compared to the light curve seen by the NAC. We derive a broad velocity distribution of the dust particles...

Keefe, Michael; It is well known that laminated composite materials are susceptible to damage by out-of-plane impact, often associated with a corresponding reduction of mechanical properties. Much research has been conducted to characterize the impact and post-impact response of various composite systems, but little attention has been given to the proximity effects of repeated impacts. Structural composite panels developed for military vehicles must survive numerous impacts of various energies with distinct damage characteristics. The size, number, and proximity of these events may have a unique influence on the structure‟s residual performance. A series of low-velocity drop-weight impact tests were conducted on S-2 glass/epoxy samples simply-supported along two edges. Three single-impact energies were used to determine the effect of damage size on the residual performance. Two of those energies were used to study the effect of impact proximity; 0.5in and 2in distances separated the two impacts. Along with damage size, the residual compressive strength and flexural properties were measured. An elastic finite element model was developed to approximate the impact damage as an elliptical inclusion. The damaged modulus and inclusion dimensions were used to uniquely determine the inclusion stiffness. The corresponding stress concentration was then used to predict the experimental loss of strength. Increasing incident impact energies exhibited greater absorbed energy...

It is accepted that during the Late Heavy Bombardment (LHB-4.2-3.8 Ga) in the Solar system, as preserved on the Moon, the terrestrial upper mantle-crust system was dominated by interactions between internal mantle processes and extraterrestrial impacts, and that following this period, the impact flux decreased by two orders of magnitude, from 4-9 × 10-13 km-2 year-1 to 3.8-6.3 × 10-15 km-2 year-1 (for asteroids Dc > = 18 km), a rate consistent with a cratering rate of 5.9 ± 3.5 × 10-15 km-2 year-1 estimated for near-Earth asteroids (NEA) and comets. Geology being a geocentric science, the assumption is generally made that from about 3.8 Ga the impact factor can be neglected in the context of models of crustal evolution, including the emergence of early continental nuclei and plate tectonics. This paradigm is questioned in this paper. From the observed minimum number of 6 continental impact structures with Dc > = 100 km [Vredefort (300 km); Sudbury (250 km); Chicxulub (170 km); Woodleigh (120 km); Manicouagan (100 km); Popigai (100 km)], assuming an Earth surface occupied by time-integrated > = 80% ocean crust since 3.8 Ga, the lower limit of post-LHB impacts is deduced at > = 30 craters with Dc > = 100 km and > = 10 craters with Dc > = 250 km. From the lunar crater counts and the present-day asteroid flux the impact incidence was likely to have been higher by an order of magnitude...

Two general classes of lunar impact breccias have been recognised: fragmental breccias and melt breccias. Fragmental breccias are composed of clastic-rock debris in a finely comminuted grain-supported matrix of mineral and lithic fragments. Impact melt breccias have crystalline to glassy matrices that formed by cooling of a silicate melt. Most lunar impact breccias in our collection probably sample ejecta from large complex craters or multi-ring basins, although linking individual breccias to specific impact events has proven surprisingly difficult. A long-standing problem in lunar science has been distinguishing clast-poor impact melt breccias from igneous rocks produced by melting of the lunar interior. Concentrations and relative abundances of highly siderophile elements derived from the meteoritic impactor provide a useful discriminant, especially when combined with petrologic and geochemical evidence for mechanical mixing. Most lunar impact melt breccias have crystallisation ages of 4.0-3.8 Ga, corresponding to an episode of intensive crustal metamorphism recorded by whole-rock U - Pb isotopic compositions of lunar anorthosites. This may reflect a short-lived spike in the cratering rate, although other explanations are possible. The question of whether or not a cataclysmic bombardment struck the Earth and Moon at ca 3.9 Ga remains open and the subject of continuing investigations.

A literatura aponta que crianças e adolescentes com enurese podem ser impactados por esse problema e seus pais podem reagir de forma intolerante à condição dos filhos. O objetivo deste estudo foi verificar se havia relação entre a intolerância dos pais e o impacto percebido pelos filhos. Verificou-se também se os níveis de impacto e de tolerância materna são diferentes entre crianças e adolescentes. Participaram 126 crianças e adolescentes, e seus pais. As crianças responderam a uma Escala de Impacto, enquanto seus pais preencheram a Escala de Intolerância. Foi encontrada correlação positiva entre a intolerância da mãe e o impacto sentido pela criança. Verificou-se também que tanto o impacto como a intolerância apresentam correlação positiva com a idade. Estes resultados indicam que o tratamento da enurese, abrangendo em conjunto os clientes e seus pais, com esclarecimentos de ambos sobre as causas da enurese e a ausência de culpa das crianças que não conseguem obter o controle vesical pode minimizar o sofrimento de ambos, mas especialmente dos primeiros. Palavras-chave: enurese; impacto psicossocial; intolerância; relações pais-filhos.; Literature shows that enuresis can affect children and adolescents that suffer from this problem.

Delivered at the CRIS2014 Conference in Rome; published in Procedia Computer Science 33 (Jul 2014).; Contains conference paper (8 pages) and presentation (19 slides).; Following the 2014 UK Research Excellence Framework (REF), attention across the Higher Education sector is turning to embedding impact measurement within the organisation. Impact is defined as the social, financial and environmental effects of research. Planning and capturing impact however is a difficult and resource-intensive activity, demanding both strategic commitment and infrastructure support. A means to systematically capture and monitor impact across the organisation is crucial to continued research success. In addition, with impact data capture as an emerging practice, there is the opportunity and necessity for a degree of standardisation in the approach to measuring impact across HEIs. Vertigo Ventures, an impact measurement consultancy, has been using and expanding its tool- VV-Impact Metrics with UK universities to support assessments by identifying impact pathways, impact indicators, evidence collection and analysis to improve the quality of the evidence and narrative. Vertigo Ventures has been working with Coventry University to use its VV-Impact Metrics tool in their self-service module (ERIC) to create a systematised data capture platform that can be readily used by the academic community to input data. This paper discusses the experience and learning from the process of embedding a solution institutionally.
