Abstract:

Abstract The specification of risk and reliability acceptance criteria is a key issue of reliability verifications of new and existing structures. Current target reliability levels in standards appear to have considerable scatter. Critical review of risk acceptance approaches to societal, economic and environmental risk indicates that an optimal design strategy is mostly dominated by economic aspects while human safety aspects need to be verified only in special cases. It is recommended to specify the target levels considering economic optimisation and the marginal life-saving costs principle, as both these approaches take into account the failure consequences and costs of safety measures.

Abstract:

Environmental engineering education at universities is a rapidly changing field globally. Traditionally it has resided in the civil engineering program addressing water and wastewater quality, treatment, design and regulatory issues. In recent years environmental engineering has become a much broader field encompassing water, wastewater, soil pollution, air pollution, risk assessment, ecosystems, human health, toxicology, sustainable development, regulatory aspects and much more. The need to introduce environmental engineering/green engineering/pollution prevention/design for the environment concepts to undergraduate engineering students has become recognized to be increasingly important. This need is being driven in part through the US Engineering Accreditation Commission Accreditation Board for Engineering and Technology criteria 2000. Thus there has been a major shift in environmental engineering education and it no longer resides only within the civil engineering discipline. This paper focuses on the development of innovative curricula for a brand new engineering program at Rowan University that integrates environmental education for all engineers. A common course known as "engineering clinic" was developed for all engineering students throughout their eight semesters of engineering education. One of the clinic goals is to integrate engineering design and the environment. The program, in its seventh year, indicates successful implementation of environmental education in all four engineering disciplines in their course work and clinics.

Abstract:

For ten years, the Division of Applied Science, University of Paderborn, has gained experience with a four-year undergraduate environmental engineering programme. Up to now, more than 400 graduates have successfully entered a professional career, proving that the educational concept is accepted by the employment sector, e.g. consultants, industry and authorities. Important aspects of this concept are the combination of civil engineering - as a core engineering field - with natural environmental sciences in the basic studies, the coverage of all environmental compartments in the main studies before specialisation in one area, and a strong practical component of the curriculum both inside and outside the university.

Abstract:

Massive grain elevators have been a dominant feature of the waterfront at Thunder Bay since 1883 when the first terminal was under construction. The earliest terminal elevators built by the Canadian Pacific Railway were constructed in the wooden crib technique on a pile foundation. By the turn of the century, the inadequacies of the crib terminals forced engineers to experiment with new materials and new design concepts for terminal elevators. Steel, tile, and reinforced concrete all came into use for terminal elevator construction between 1898 and 1903. By 1910, the plan of the elevator had evolved from a single building into four separate structures. The appearance of the typical Lakehead terminal elevator today is the result of these engineering experiments which occurred at the end of the nineteenth century and in the early years of the twentieth. Key words: grain elevators, concrete construction, slip forms, formwork, bins, silos, timber construction, crib walls, cribs, steel construction.

Abstract:

Abstract Special-purpose river port sediment was investigated for its potential use as a road construction material. Sediment samples were extracted from three locations in three small river ports, and detailed laboratory research was conducted to determine its basic mechanical properties and characteristics that can potentially have an adverse influence in a roadside environment. The results of the research conducted indicate that there is a need for systematic monitoring of the quality and quantity of sediment in special-purpose river ports of the Danube River Basin to maintain its mobility and prevent flooding. The basic engineering characteristics (Proctor elements, Atterberg limits, California bearing ratio, and unconfined compressive strength) determined represent the good potential of the sediment samples tested herein for use in road construction. In addition, the chemical characteristics tested indicate the need for detailed analyses of the potential environmental risk before application in civil engineering structures

A major drawback of the traditional output queuing technique is that it requires a switch speedup of N, where N is the size of the switch. This dependence on N makes the switch non-scalable at high speeds. Input queuing has been suggested instead. The introduction of input queuing creates the necessity for developing switching algorithms to decide which packets to keep waiting at the input, and which packets to forward across the switch. In this thesis, we address various algorithmic aspects of switching. We prove in this thesis, that many of the practical switching algorithms still require a speedup to achieve even a weak notion of throughput. We propose two switching algorithms that belong to a family to which we refer in this thesis as priority switching. These two algorithms overcome some of the disadvantages in existing priority switching algorithms, such as the excessive amount of state information that needs to be maintained. We also develop a practical algorithm that belongs to a family to which we refer in this thesis as iterative switching. This algorithm achieves high throughput in practice and offers the advantage of not requiring more than one iteration, unlike other existing iterative switching algorithms which require multiple iterations to achieve high throughput. Finally, we address the issue of using switches in parallel to accommodate for the need of speedup. We study two settings of parallel switches, one with standard packet switching, and one with flow scheduling, in which flows cannot be split across multiple switches.

Abstract:

Water, otherwise known as the pool of life, is the very essence of all living things and as such is vital for survival, whether for living beings, social, economic development or for environmental sustainability. However, its continuing existence is severely threatened for future as a result of climate change, carbon footprint, population growth, environmental damage, combined with natural disasters like droughts and floods. The prospect of an alternative solution such as desalination of sea or brackish water to counter the limit on conventional water resources such as groundwater, which cannot meet demand, is therefore very promising, particularly in arid and semi-arid regions where water scarcity and impaired quality prevails. Consequently, desalination technology has now become a burgeoning industry in North Africa or southern Mediterranean countries, such as in Libya. However, evidence suggests that as a result of by-products being discharged directly into the sea, particularly from coastal desalination plants, the physico-chemical parameters of the receiving water are changing and posing a threat to marine ecosystems. As a result of studies conducted on these parameters to analyse the brine emitted from the Zwuarah and the West Tripoli distillation plants (ZWDP & WTRIS) on the Libyan coastline, evidence shows there is a significant positive correlation at both sites between the biological data and physico-chemical parameters (rs=0.673; p=0.002) and (rs=0.637; p=0.003), which is a clear indication of the impact of brine disposal from both plants on the marine environment. For most of coastal desalination plants on the Libyan coastline, the most practical and least expensive brine disposal option is to discharge it into the sea. It is necessary therefore, to effectively manage desalination reject brine in order to ensure more efficient disposal and reuse. Therefore, it is suggested that experimental studies are aimed for dual benefit of on-site generation of sodium hypochlorite through brine electrolysis and to recover minerals and NaCl from the brine using evaporation ponds, while protecting the environment. Following the first experiment, the outcome of brine utilisation showed a significant production of NaOCl using graphite electrodes (MCCA 1.82 gr/m3). At interelectrode spacing 2 cm and 4 cm, the power consumption was higher, with a greater concentration of sodium hypochlorite generation varying between 10-25 kw/m3 (573-2140ppm) and 29-24 kwm-3 (572-2600ppm) than at interelectrode spacing 6cm 17-13 kwm-3 (350-1790ppm). Consequently, the selection of an optimum electrical consumption level is key in establishing the best scenario in terms of economy and efficiency. Subsequent to the second experiment of brine evaporation in the ponds, results showed that the evaporation rate in August was lower than in September (9.06 mmday-1, 14.63 mmday-1) respectively. The results of the SEM/EDS test showed that due to elevated surges of Na+ and Cl-, halite (NaCl) was the main mineral evident during crystallisation of the salt samples. Hence, the two experiments reveal that brine can be recycled productively, while protecting the environment.

Abstract:

Many decision-making situations today affect the safety of individuals and the environment,for instance hazardous waste management. In practice, many of these decisions are madewithout an overall view and with the focus on either the environment or safety. Now and then the areas of regulation are in conflict, i.e. the best alternative according to environmental considerations is not always the safest way and vice versa.A tool for taking an overall view within the areas of safety and environment would simplify matters and provide authorities and industry with a better basis for their work. This thesis forms part of a project which aims to develop a framework tool giving this overall view and supporting decision-making in which the issues (areas) of environment, safety, ethics and costs are all integrated. By developing a framework tool, different areas of interest could be taken into consideration more easily when a decision is to be made and could also help develop legislation and policy locally (at an industry or company), nationally and internationally. The project also aims to provide knowledge about different destruction/decommission methods, their good and bad points and their consequences, in order to provide different actors with a better basis for decision-making. This thesis focuses on development of the framework. The scope of the studies was restricted to environment, ethics and personnel safety due to the extent of the work and time limitations. In the next part of the project, the areas of costs and evaluation will be studied and a first draft of the framework tool will be presented. In order to develop the framework tool, two case studies were carried out here: an environmental analysis involving a life cycle assessment and an ethical analysis. With the help of these analyses, three different methods of destruction of ammunition were compared: Open detonation, modelled both with and without recovery and recycling of metals; incineration in a static kiln with air pollution control combined with recycling of metals, modelled with two different levels of air emissions; and a combination of incineration with air pollution control, open burning, recovery of some energetic material and recycling of metals, giving a total of five options. Every method of destruction of energetic material, i.e. explosive waste or ammunition, results in environmental impacts in both the short and long term. These environmental impacts have direct or indirect impacts on safety, quality of life, the economy, etc., now and in the future, locally and globally. Life cycle assessment revealed two factors of importance for reducing the environmental impacts: Recycling the metals and air pollution control. As a consequence of controlling these potential negative environmental impacts, safety problems might also be controlled. Ethical analysis revealed that future generations and people in foreign countries will be affected by the destruction of ammunition. When choosing a method for destruction of ammunition, this group (the general public) should thus be given special attention.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2010.
Cataloged from PDF version of thesis. Page 114 blank.
Includes bibliographical references (p. 109-113).
This thesis compares alternative and proposes new candidate algorithms for the online calibration of Dynamic Traffic Assignment (DTA). The thesis presents two formulations to on-line calibration: 1) The classical statespace formulation and 2) The direct optimization formulation. Extended Kalman Filter (EKF) is presented and validated under the state-space formulation. Pattern Search (PS), Conjugate Gradient Method (CG) and Gradient Descent (GD) are presented and validated under the direct optimization formulation. The feasibility of the approach is demonstrated by showing superior accuracy performance over alternative DTA model with limited calibration capabilities. Although numerically promising, the computational complexity of these base-line algorithms remain high and their application to large networks is still questionable. To address the issue of scalability, this thesis proposes novel extensions of the aforementioned GD and EKF algorithms. On the side of algorithmic advancement, the Partitioned Simultaneous Perturbation (PSP) method is proposed to overcome the computational burden associated with the Jacobian approximation within GD and EKF algorithms. PSP-GD and PSP-EKF prove to be capable of producing prediction results that are comparable to that of the GD and EKF, despite achieving speed performance that are orders of magnitude faster. On the side of algorithmic implementation, the computational burden of EKF and GD are distributed onto multiple processors. The feasibility and effectiveness of the Para-GD and Para-EKF algorithms are demonstrated and it is concluded that that distributed computing significantly increases the overall calibration speed.

Abstract:

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2007.
Includes bibliographical references (leaves 119-126).
Microbial water quality analyses were conducted on 15 samples of factory-produced sachet water and 15 samples of hand-tied sachet water, sold in Tamale, Ghana. The tests included the membrane filtration (MF) test using mColiBlue24® medium, 3MTM PetrifilmTM test, and Hydrogen Sulfide Presence Absence (P/A H2S) test. With the MF method, 1 factory-produced and 1 hand-tied sachet-water sample had E.coli counts of 5 CFU/100ml and 49 CFU/100ml respectively. Almost half (47%) of the factory-produced sachet-water samples had some total coliforms (range from 1 CFU/100ml to 115 CFU/100ml). All the 15 hand-tied sachet-water samples had total coliforms (range from 4 CFU/100ml to 2010 CFU/100ml). One sample recorded TNTC at a dilution factor of 10. The MF method showed little correlation with the 3MTM PetrifilmTM method (R=0. 16). With the 3MTM PetrifilmTM test method, none of the factory-produced sachet-water samples had E.coli and only one sample had total coliforms with 100 CFU/100ml. The hand-tied sachet-water sample with 49 E.coli CFU/100ml in the MF test, turned out to have 100 CFU/100ml in the 3MTM PetrifilmTM test. The MF test results were considered more reliable.
(cont.) For the P/A H2S test, 7% of factory-produced sachet-water samples and 27% of the hand-tied sachet-water samples returned positive results. Overall, hand-tied sachet water was found to be two times more microbially contaminated than factory-produced sachet water. Turbidity tests done on the samples showed that 93% of the hand-tied sachet-water samples and 20% of factory-produced sachet-water samples had turbidities greater than 5 NTU - the limit set by the 1998 Ghana Standards for drinking water. Out of 30 random passer-byes in Tamale and neighboring Savelugu that were interviewed, all drank sachet-vended water, signifying its popularity in the areas. For 37%, sachet water formed the sole supply of drinking water, even at home! 70% drank more water when away from home, 20% the same amount at home and away from home, while 10% drank more water at home. Sachet water formed the main source of water away from home. Sachet-water vendors made 100% to 400% profit.

Full text

Abstract:

This thesis examines the retention of three heavy metals (Pb, Cu, Zn) on a predominantly illite clay soil initially saturated with calcium and magnesium. The heavy metal retention mechanisms were examined both experimentally, using batch equilibrium and precipitation tests, and analytically, using the geochemical equilibrium speciation model MINTEQA2. Heavy metal retention was examined in both non-competitive (single metal) situations and competitive (multi-metal) situations. A definite adsorption selectivity order of Pb $>$ Cu $ gg$ Zn was established, as has been found by many other researchers. Retention by ion exchange adsorption was observed by comparing the total amount of heavy metals retained to the total amount of initially adsorbed calcium and magnesium released. In most cases, it was found that ion exchange was the dominant retention mechanism, even at neutral equilibrium pH values. The effect of initial heavy metal solution pH on heavy metal retention was explored. A comparison was made between batch equilibrium tests performed with metal solutions adjusted to an initial pH of 3 and tests performed with metal solutions that were not adjusted and thus at a higher initial pH. In many cases it was found that greater overall retention occurred when initial metal solutions were at a pH of 3 as opposed to a higher initial pH. The speciation modelling, when compared to the experimental results, was found to adequately predict heavy metal retention in simple single metal batch equilibrium tests but in more complicated multi-metal scenarios the modelling had limited success.

Abstract:

The built environment contributes extensively to the overall environmental impact of society. An increasing number of tools have been developed worldwide for comprehensive environmental assessment and rating of buildings in order to make the building sector more sustainable. These tools are expected to drive and facilitate future environmental improvements and market transformation in the sector. This thesis explores different methodological aspects in tool development using experiences from two large Swedish projects, the EcoEffect and ByggaBo tools, which were developed with a high level of stakeholder participation in order to be of practical use in the building sector. The methodological aspects explored and discussed here include an approach for systematic selection of assessment aspects (energy use, indoor air quality, etc.) in tools (Paper 3), and a systematic procedure for selecting practical indicators using theoretical (e.g. validity/environmental relevance) and practical (e.g. costs) criteria (Papers 2 and 3). An approach for simple communication of complex results is presented with examples from 26 multi-family buildings (Paper 4). This approach allows a building’s ‘environmental efficiency’ to be presented in one diagram, without weighting the two distinct assessment areas energy use and indoor environmental quality. Paper 5 discusses the contextual issue of internal use of environmental indicators in property management organisations through reviews of environmental performance evaluation and organisation theory literature and comparisons with actual case studies. The EcoEffect (Paper 1) and the ByggaBo tools are also compared and summarised. The case studies of real buildings and experiences from the EcoEffect and ByggaBo projects allowed data collection, calculation procedures and different practical applications of such tools to be evaluated. Poor data availability sometimes limits assessments, and improved internal routines and database developments in the building sector would allow more reliable environmental assessments. Reviews of numerous indicators in Paper 3 (and 2) and literature revealed that environmental relevance was not a key aspect when current environmental performance indicators and building rating tools were constructed. This thesis suggests that environmental relevance and systematic procedures be prioritised in order to provide robust and trustworthy tools for environmental assessment of buildings. Recommendations, some of which are generally applicable to other environmental assessments, include selection of environmentally relevant indicators, systematic procedures for handling theoretical and practical considerations in tool development, aggregation and weighting methods, use of a life cycle perspective and inclusion of performance-based rather than feature-based indicators. Since it is likely that the information these tools provide will increasingly be used by authorities, building users, economic incentive providers such as banks, etc., the methodological developments suggested here to strengthen tool rigour are important for future tool development processes.
Utvecklingen av verktyg för miljöbedömning av byggnader är ett område som expanderat kraftigt sedan 1990-talets början. Den ökande medvetenheten om den byggda miljöns omfattande bidrag till samhällets miljöpåverkan i stort har spelat stor roll för denna utveckling. Verktygen förväntas ha en betydelsefull roll i att driva på och underlätta miljöförbättringar och omdaning av marknaden i bygg- och fastighetssektorn. Denna avhandling utforskar olika metodaspekter för verktygsutveckling och bygger på erfarenheterna från två stora svenska metodutvecklingsprojekt för miljöbedömning av byggnader, EcoEffect och ByggaBo:s miljöklassning av byggnader. Båda dessa verktyg togs fram i samarbete med ett stort antal representanter från bygg- och fastighetssektorn, då verktygen syftade till praktisk användning. Ett antal metodaspekter utforskas och diskuteras i avhandlingen. I artikel 3 föreslås och testas ett angreppssätt för systematiskt urval av miljöaspekter som ska bedömas av ett verktyg och dessutom föreslås här och i artikel 2 ett systematiskt tillvägagångssätt för att välja indikatorer för praktiskt användning utifrån både teoretiska (t ex. validitet) och praktiska (t ex. kostnad) kriterier. Ett angreppssätt för att underlätta kommunikation av komplexa miljöbedömningsresultat presenteras genom exempel från 26 flerfamiljshus i artikel 4. Detta angreppssätt möjliggör att redovisa en byggnads ‘miljöeffektivitet’ i ett diagram utan att behöva vikta de två disparata miljöaspekterna energianvändning och innemiljö. Artikel 5 tar upp användning av miljöindikatorer för internt arbete i fastighetsförvaltande organisationer genom litteraturöversikter inom områdena utvärdering av miljöprestanda och organisationsteori samt genom jämförelser med praktiska fallstudier. Verktygen EcoEffect (artikel 1) och nuvarande version av ByggaBo:s miljöklassningssystem sammanfattas också och jämförs i avhandlingen. Genom ett antal fallstudier av verkliga byggnader och erfarenheterna från EcoEffect- och ByggaBo-projekten utvärderas frågor som insamling av indata, beräkningsmetoder och olika praktiska tillämpningar i avhandlingen. Dålig tillgång på indata begränsar ibland möjligheterna att göra miljöbedömningar. Förbättrade interna rutiner samt utveckling av nya typer av databaser inom bygg- och fastighetssektorn kommer med största sannolikhet att underlätta miljöbedömningar i framtiden. Granskning av ett stort antal miljöindikatorer i artikel 3 (och 2) och litteratur på området visade att när miljöindikatorer och miljöklassningsmetoder tagits fram, har miljörelevansen hos dessa sällan haft högsta prioritet. Ett övergripande mål för denna avhandling har därför varit att bidra med rekommendationer som kan stärka miljörelevansen och trovärdigheten hos liknande indikatorer och verktyg. Några av de angreppssätt som föreslås är tillämpliga mer generellt också för andra typer av miljöbedömningar; t ex. hur miljörelevanta miljöindikatorer kan väljas, hur både teoretiska och praktiska överväganden kan hanteras på ett systematiskt sätt vid liknande verktygsutveckling, angreppssätt för viktning och aggregering av resultat samt användning av ett livscykelperspektiv. Vid miljöbedömning av byggnader bör också funktionsbaserade indikatorer i första hand väljas snarare än sådana som baseras på specifika tekniska utföranden. En trolig utveckling är att nya typer av användare i större utsträckning kommer att efterfråga den information som miljöbedömningsverktyg för byggnader kan tillhandahålla. Det kan handla om t ex. myndigheter, husköpare och ekonomiska incitamentsgivare såsom banker. Av denna anledning är de frågor som rör metodutveckling och tas upp i avhandlingen, klart betydelsefulla för att stärka noggrannhet, robusthet och trovärdighet i framtida utveckling av miljöbedömningsverktyg för byggnader.

Abstract:

This contribution is particularly focused on the lifetime assessment of structures where the concept of risk informed decision is based on the structural performance. Regarding the lifetime performance of structures general aspects such as structural system, component-system performance assessment, the concept of robustness in the component-component-system interaction and its assessment framework are introduced. Furthermore, aspects of both deterministic and probabilistic performance evaluation approaches were investigated, while extra emphasis is given to the probabilistic performance assessment approaches. This illustration of the probabilistic performance approaches includes the concepts of uncertainty quantifications, hazard identification methods and techniques, and the formulation of random variables and stochastic structural deterioration processes. In addition, lifecycle performance assessment and prediction methods, approaches and tools for engineering structures are presented.

Abstract:

University studies for the architecture degree in Spain give very little weight to considerations related to the design of a healthy interior environment. The low number of subjects related to interior comfort criteria may cause the student to underestimate the importance of environmental design of closed spaces in favor of aesthetic or merely functional aspects. However, there is a direct relationship between formal design decisions and environmental conditions in buildings, and future architects must understand those connections in order to make designs that combine efficiency and high aesthetic value. In this chapter, several pedagogical strategies are presented to get architecture students to learn and internalize the link between design and interior conditions, aiming at the acquisition of an adequate environmental awareness.

Abstract:

Sustainable construction is the process of constructing structures while being environmentally conscious of the material, design process, and sustainability of the structure and the effect it has on the environment. In simple terms, it is the process of creating structures in an environmentally friendly way. Sustainability factors are considered in the design, material, longevity, and future deconstruction as the main aspects. Also, to determine what is “allowed” and what may deem “disallowed”. The basic six sustainable practices / principles are optimizing site potential, sustainable energy use, protect and conserve water, optimizing material usage and building space, effective operational and maintenance practices and enhancing indoor environmental quality.

Abstract:

Nowadays, construction management is the main challenge for civil engineering corporations mainly due to the large number of information collected daily. In parallel, the adoption of paper based resources in the management process increases the chances of obtaining inefficient results. Besides that, it is important to care about environmental aspects, where each construction must be less harmful to nature. In this context, this paper presents Bentham Obras, a system based onWeb and Mobile platforms that provides several management processes, such as financial monitoring, work schedule, task execution control and contract accomplishment. After using the system for a period of 8 months, civil engineering corporations that have adopted the system highlighted the important aspects brought by Bentham Obras in the construction management.

Abstract:

In Iraq, the two dominating surface water sources are Tigris and Euphrates Rivers in which some dams constructed on both of them forming reservoirs. Haditha Dam reservoir is one of the most essential sources of drinking, irrigation, flood control and hydropower generation in Anbar State, Western Part of Iraq. Besides, the reservoir is a unique habitat with a wide spectrum of biodiversity. The objective of this study is to investigate and monitor the water quality in Haditha Dam reservoir and introduce the Multi Criteria Analysis (MCA) to highlight the best runoff control measure depending on selected criteria and criteria weights. Experts were interviewed for the selection of criteria and for the assignment of the weight factor and scores. Four criteria from three categories such as technical, economic and environmental aspects were selected. Results from this study indicated that a distinguished difference in TSS and Turbidity between the dry and wet seasons and necessitates the installation of runoff control measures. It was found that the soil binders, sediment basin and diversion channel are the best alternatives for controlling erosion, sediment and drainage respectively. The sensitivity analysis showed very strong decision made by the experts for the technical, economic and environmental criteria.

Abstract:

The process of construction can be defined as an extensive system that builds the accommodations for people to settle in, as well as the construction of facilities that keep up the development process. Some of the main steps that the process would cover are the extracting and benefiting raw materials, manufacture of building materials and elements, the construction of the project run from viability to inspection, and the regulation and running process of the sites. The most profound challenges that many cities n Iraq share illustrate the consequences of urban growth. Thus, this study seeks to examine the aspects of sustainability that influence the decisions for the process of building up green building projects. A total number of fourty respondents have been requested to evaluate nine elements of building sustainability: life cycle evaluations, energy conservation and renewable energies, water conservation, environmentally friendly construction supplies and standards, depletion of waste materials, alleviation of toxic materials, adequate indoor ventilation, smart innovation, and sustainability in the development of the building process and ecologically friendly construction projects. The findings show that the respondents preferred the use of elements that could give better sustainability in the process of construction building to ensure a healthier and better quality of life. This preference is established from the concept of green building technology. The most chosen aspect for this concept is the efficiency of energy and the use of renewable energy, followed by the alleviation of toxic materials, adequate indoor ventilation, and water conservation.

Abstract:

Over the past few years, great concern has been raised about the impact of commercial aviation on the environment. In a Business As Usual approach, the expected growth in air traffic is going to affect climate change even more unless mitigation policies are devised and implemented. Although there is a tendency to focus on long-term technological solutions and breakthroughs, short-term improvements applicable to existing aircraft/engine configurations are also very important to fully realise the benefits of new technologies. Aircraft trajectory optimisation presents the opportunity to effectively reduce fuel consumption and pollutants emitted providing a feasible short-term strategy to be applied to the existing aircraft fleet. The present study focuses on preliminary results obtained using a multi-disciplinary aircraft trajectory optimisation simulation framework. Three in-house computational models are implemented in the framework to model the aircraft and engine performance, as well as to predict the level of gaseous emissions produced. A commercially available optimiser is integrated within the framework to analyse and optimise single flight path elements (e.g., climb), as well as the entire flight profile. For the purpose of this study, the climb and the whole flight profile are divided in four and eight segments respectively. Trajectory optimisation processes are then carried out in order to minimise three different objective functions: flight time, fuel burned, and mass of oxides of nitrogen (NOx) emitted. The results of the trajectory optimisation processes performed confirm the validity, effectiveness, and flexibility of the methodology proposed. In future, it is expected that these types of approaches are utilised to efficiently compute complete, optimum and ‘greener’ aircraft trajectories, which help to minimise the impact of commercial aviation on the environment. Other computational models that simulate several other aspects such as aircraft and engine noise, weather conditions and contrails formation, among others, need to be also included in the optimisation processes.

Abstract:

Since its establishment in 2005 the Nuclear Decommissioning Authority (NDA) has a remit to maintain the skillsbase for safe, secure and cost effective decommissioning of the existing UK civil nuclear power plants and associated facilities. With an aging workforce and a competitive tender process for each project a number of new companies are realising the potential of the UK decommissioning market. The Nuclear Engineering Doctorate and NTEC Masters Programmes have been designed to provide the nuclear workforce of the future. The doctorate is a partnership between industry, a university partner and the research engineer with the benefit to industry that the research engineer is based with the industrial partner. Technical and management modules are studied at the university whilst the research project is carried out in the industrial environment. The Masters programme draws on the expertise of 11 Higher Education Institutes and offers over 20 modules that are delivered in a short-fat format either as stand alone CPD courses or, by taking further modules, a certificate, diploma or on completion of a research project an M.Sc. Modules are available that cover the technical aspects of decommissioning as well as management of the decommissioning process. The availability of modules in a Distance Learning format now enables students based around the world to benefit from this programme. This paper will describe the two programmes in detail and provide examples of current projects that are delivering the research and workforce required for a successful decommissioning programme.

Quinn, Meghan. Geotechnical effects on fiber optic distributed acoustic sensing performance. Engineer Research and Development Center (U.S.), July 2021. http://dx.doi.org/10.21079/11681/41325.

Full text

Abstract:

Distributed Acoustic Sensing (DAS) is a fiber optic sensing system that is used for vibration monitoring. At a minimum, DAS is composed of a fiber optic cable and an optic analyzer called an interrogator. The oil and gas industry has used DAS for over a decade to monitor infrastructure such as pipelines for leaks, and in recent years changes in DAS performance over time have been observed for DAS arrays that are buried in the ground. This dissertation investigates the effect that soil type, soil temperature, soil moisture, time in-situ, and vehicle loading have on DAS performance for fiber optic cables buried in soil. This was accomplished through a field testing program involving two newly installed DAS arrays. For the first installation, a new portion of DAS array was added to an existing DAS array installed a decade prior. The new portion of the DAS array was installed in four different soil types: native fill, sand, gravel, and an excavatable flowable fill. Soil moisture and temperature sensors were buried adjacent to the fiber optic cable to monitor seasonal environmental changes over time. Periodic impact testing was performed at set locations along the DAS array for over one year. A second, temporary DAS array was installed to test the effect of vehicle loading on DAS performance. Signal to Noise Ratio (SNR) of the DAS response was used for all the tests to evaluate the system performance. The results of the impact testing program indicated that the portions of the array in gravel performed more consistently over time. Changes in soil moisture or soil temperature did not appear to affect DAS performance. The results also indicated that time DAS performance does change somewhat over time. Performance variance increased in new portions of array in all material types through time. The SNR in portions of the DAS array in native silty sand material dropped slightly, while the SNR in portions of the array in sand fill and flowable fill material decreased significantly over time. This significant change in performance occurred while testing halted from March 2020 to August 2020 due to the Covid-19 pandemic. These significant changes in performance were observed in the new portion of test bed, while the performance of the prior installation remained consistent. It may be that, after some time in-situ, SNR in a DAS array will reach a steady state. Though it is unfortunate that testing was on pause while changes in DAS performance developed, the observed changes emphasize the potential of DAS to be used for infrastructure change-detection monitoring. In the temporary test bed, increasing vehicle loads were observed to increase DAS performance, although there was considerable variability in the measured SNR. The significant variation in DAS response is likely due to various industrial activities on-site and some disturbance to the array while on-boarding and off-boarding vehicles. The results of this experiment indicated that the presence of load on less than 10% of an array channel length may improve DAS performance. Overall, this dissertation provides guidance that can help inform the civil engineering community with respect to installation design recommendations related to DAS used for infrastructure monitoring.
