Full textAbstract:
The purpose of this feasibility study has been to guide decision makers in the implementation of abiogas project for the region of Sønderborg, Denmark. The project has been part of Feasibility studies envisioned in the Master Plan for Sønderborg to go carbon neutral by 2029. The study tried to evolve abest alternative for the city and gives a ready document to refer all aspects of biogas. The intensive industrial farming in Sønderborg needs to evolve to compare favorably with the situationin other regions of Denmark. The interests of various stakeholders in the waste cycle should be alignedwith that of farming. Interesting developments in the Bioenergy space hold promise for farmers to usetheir capacities for additional or alternative livelihood in energy. The focus to promote biogas as part ofDanish energy strategy and multiply capacity over the next 3 years has attracted numerous biogas proposals all over Denmark. This study had started off with identifying and estimating very obvious substrate sources. At verymoderate assumptions the value of methane in these sources has been estimated at 9 million m3. Thispotential could easily be increased if economically feasible substrates like energy crops and algae areadded. The SWOT analysis of pig farming in the region brings out the perspectives of farming direction in the near future. The 5 scenarios developed help the decision maker understand the various aspects thatneed to be carefully considered when planning the plant. The best case scenario for the city would bethe energy mosaic scenario which would integrate the high tech focus of local industry, a renewable energy source and a showcase project to make the region stand out among the other regions focused inthe climate change debate. The technological system analysis should help decision makers understand the stakeholders and the various dimensions in biogas that although complicated are manageable. The business case approach to identify utilization of energy and its costs gives a clear picture on the need for using the energy in CHP.The present focus by potential investors on government subsidies to calculate profitability needs to be understood in the context of other similar plants accepting present subsidy levels and the societal benefits, which unfortunately cannot be valued in money terms. At the center of all this is the need for proper stakeholder management within a bound timeframe asidentified by the “Create acceptance process”. The various tools and data are all present in this study,that only need to be arranged and presented by the company eventually handling the strict Projectmanagement goals of this project.www.ima.kth.se

Full textAbstract:
The Tendertips Company (TTC) is an asparagus growing a packing business which has a problem. Not enough New Zealanders are willing to manually harvest asparagus. Samoan workers are being employed through the recognised seasonal employer (RSE) scheme which incurs a large cost to TTC. This scheme is also susceptible to a change in government policy at any time.
Automated asparagus harvesters have been designed in the past however they inflict too much damage to asparagus plants and the paddocks in which they grow. Several research projects have also been undertaken to minimise this damage while robotically harvesting asparagus however no solutions currently exist.
In this project a low-cost system was designed and constructed to determine the feasibility of selectively harvesting asparagus without inflicting damage to asparagus plants or the paddock. The most technical component in this system was identified, accurately identifying and locating asparagus spears to be harvested.
A camera and lighting system, along with an asparagus data logging system was designed and tested, with the assumption that if this system succeeded, the development of an automated asparagus harvester would have a very high chance of success. The system proved that individual asparagus spears can be located accurately enough so as not to inflict damage on other spears during the harvesting process:
• 96.8% of asparagus spears were located.
• Average location error of 3.0mm.
The measurement of the size and height of asparagus spears was not very accurate due to the lighting system, however this is expected to be fixed with a design change.
A global positioning system (GPS) successfully saved the calculated size of the asparagus spear with its global location to allow for analysis of the asparagus paddocks using the Google Earth application.
The cost of robotically harvesting asparagus is forecast to be much less than manual harvesting:
• Manual harvesting cost $1.40 per kilogram
• Forecast robotic harvesting cost $0.41 per kilogram.
If one other investor was obtained to create a new business, which developed an automated asparagus harvester before harvesting asparagus in New Zealand and California, the forecast financials are:
• Net present value (NPV) of $1.613 million after ten years.
• Internal rate of return (IRR) of 33% after ten years.
• Maximum accumulated investment from TTC of $449,000 four years after development first begins.
The forecast income is through harvesting asparagus only as selling the machines or leasing the intellectual property is not viable.
A guiding document was created to guide TTC with the development of an automated asparagus harvester if it aligns with their business model.
The development of an automated harvester:
• Is technically viable.
• Will lower harvesting costs.
• Will ensure all of TTC’s asparagus is harvested when required.
• Will return sustainable profits to the child business that TTC should create.
The project management techniques adopted in this project ensured the project was completed on the planned day of completion, while remaining on budget:
• Budgeted cost of work scheduled $24,478.21
• Budgeted cost of work performed $24,027.54

EMBAEMBA Project Report
"This project was completed by Corpus Christi One, on behalf of Chief of Naval Air Training's Deputy Assistant Chief of Staff for Training and Standardization (CNATRA N7), and facilitated through the Naval Postgraduate School Executive MBA program. The purpose is to analyze CNATRA's current model of producing and distributing flight training-related publications to student military aviators (SMAs) in hard-copy format, and to compare that model with a program instead using electronic book readers (e-readers) and digitized versions of these same publications to determine whether or not such a model would be technically feasible, and whether or not such a course of action might allow cost savings to be realized over the current practice. This study focuses on a single flight training squadron: Training Squadron TWO EIGHT (VT-28) based at NAS Corpus Christi. In addition to historical data obtained from VT-28 with regard to SMAs trained annually, interview data was obtained from subject matter experts involved in the ordering, production, inventory, and issuance of flight training publications, as well as the manufacture of e-readers and digital conversion of documents. Our analysis compares and contrasts three possible courses of action: _ COA 1: Purchase e-readers to support the total number of SMAs trained each year. SMAs will then keep the e-reader they have been issued. _ COA 2: Purchase e-readers to support only the maximum number of SMAs in training at any given time. E-readers will be returned for re-issue. _ COA 3: Continue to produce and distribute flight training publications in hardcopy format. While all three COAs would meet the instructional needs of both CNATRA and the SMA, we believe that COA 3 provides the best, most economical solution within the constraints of this project. In order to realize cost savings through e-reader use, it must be implemented far more comprehensively than merely in a single unit or phase of flight training."

Korhonen, Daniel. "Wheel alignment method feasibility study." Thesis, KTH, Fordonsdynamik, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-280555.
Full textAbstract:
Throughout the history of motor vehicles, the tyres have always been consideredas one of the most important components of the vehicle due to their interactionwith the road. One important aspect is the wheel alignment, with the purposeto adjust the static wheel angles that are essential for many reasons, such assafety and fuel consumption for instance. Despite the numerous methods forwheel angle measurements, there seems to be no existing technical solutionbased on computer vision, that is suitable for residential use, regarding bothcost and size of the equipment. The study aims to investigate the feasibility ofsuch a system.The proposed system is based on planar fiducial markers called ArUco.From images or video frames of the marker, the pose of the marker can beestimated. Thus, by placing such markers on the ground, on the wheel andon the vehicle, the estimated pose of the markers can be used to measure andcalculate the wheel alignment parameters. Only toe and camber angles aremeasured within the scope of this thesis, even if the system has the potential tomeasure other wheel alignment parameters as well.After camera calibration, simplified ArUco marker tests were done by measuringthe known displacement and inclination of a marker with respect to areference marker. The mean absolute error was 030400 and 0:024mm for theinclination angle and displacement, respectively. Furthermore, the toe and camberangles of a vehicle were measured and compared to reference measurementsperformed with a commercial wheel alignment system, giving mean absoluteerrors of 0520 and 0280 for the camber and toe angles, respectively. Despitethe relatively large errors for the toe and camber angle measurements, theresults from the initial inclination and displacement tests show the potential ofthe system. In addition, several error sources and suggestions for improvementcan be identified.As a conclusion, the proposed system can be considered a working firstprototype, which after improvement and optimisation has the potential tobecome a feasible alternative, especially for residential use and for mobileworkshops due to the low cost, size and usability of the system.Inom fordonstekniken har däcken alltid betraktats som en av fordonets viktigastekomponenter på grund av deras interaktion med vägen. En viktig aspektär hjulinställning, med syftet att justera de statiska hjulvinklarna som är viktigaav många anledningar, som exempelvis säkerhet och bränsleförbrukning.Trots flera metoder för mätning av hjulvinklar verkar det inte finnas någonbefintlig teknisk lösning baserad på datorseende, som är lämplig för privat brukbåde gällande kostnad och storlek på utrustningen. Syftet med studien är attundersöka genomförbarheten för ett sådant system.Det föreslagna systemet är baserat på plana ArUco-markörer. Från bildereller bildrutor i en video av markören kan dess läge uppskattas. Genom attplacera sådana markörer på marken, på hjulet och på fordonet, kan såledesmarkörernas uppskattade lägen användas för att mäta och beräkna hjulvinklarna.Endast toe- och cambervinklar mäts inom ramen för detta examensarbete, ävenom systemet också kan mäta andra hjulvinklar.Efter kamerakalibrering utfördes enkla ArUco-markörtester genom att mätaden kända förskjutningen och vinkeln av en markör i förhållande till en referensmarkör.De genomsnittliga absoluta felen var 030400 och 0:024mm förvinkeln respektive förskjutningen. Vidare mättes toe- och cambervinklar påett fordon och jämfördes med referensmätningar utförda med ett kommersiellthjulinställningssystem. De genomsnittliga absoluta felen var 0520 och 0280för camber- respektive toevinkeln. Trots de relativt stora felen i mätningarnaav toe- och cambervinklar visar resultaten från de första testerna systemetspotential. Dessutom kan flera felkällor och förslag till förbättringar identifieras.Som en slutsats kan det föreslagna systemet betraktas som en fungerandeförsta prototyp, som efter förbättring och optimering har potential att bli ettmöjligt alternativ, särskilt för hemmabruk och för mobila verkstäder på grundav låga kostnader, systemets ringa storlek och användbarhet.

Full textAbstract:
Dignity therapy, which has recently been developed to reduce psychosocial and spiritual distress in terminally ill patients, has stimulated substantial interest worldwide. This study aimed to explore the experiences of specialist palliative care patients in Scotland undertaking dignity therapy and to establish whether or not they would recommend it to fellow patients. Eight patients (seven female and one male) participated in the Dignity Psychotherapy Question Protocol (DPQP) followed by a semi-structured research interview. The interviews were recorded and transcribed verbatim, before being analysed using a grounded theory approach to develop a provisional framework. The findings suggest that patients perceived dignity therapy in a predominantly positive light. They considered the patient-researcher rapport, in terms of listening and compassion, to be especially helpful and to have facilitated the therapeutic encounter. The analysis also identified four beneficial components of this therapy: a) looking back; b) sharing their memories; c) getting things off their chest; and d) putting their story on paper. Based on their experiences, the majority of patients reported that they would recommend this intervention to fellow patients. Whilst several of the benefits of dignity therapy reported by patients correspond to findings of previous dignity therapy studies, many also fit with benefits reported in the literature from other life review processes. Consequently, it is unclear if dignity therapy is unique as claimed. It is also unclear which features of the rapport were attributable to therapist-specific factors and which may be credited to the intervention itself. Results suggest dignity therapy is feasible for patients with advanced illness and may even benefit those without observable psychological distress. Nevertheless, given the small sample studied, further research is needed to corroborate these findings.

Full textAbstract:
The 1991 Gulf War revealed to U.S. military planners a serious weakness in the ability of our nation's armed forces to detect and destroy mobile theater ballistic missiles systems before an enemy has the chance to use these weapons at least once, and in some cases, multiple times. Since that time there have been various studies done to show that unmanned air vehicles (UAVs) could be used to more effectively locate these mobile missile threats. However, few, if any studies, have addressed the subject of using these same UAVs to not only locate an enemy target, but to also destroy it. Therefore, this thesis provides a survey of both recent and expected future advances in UAV technology with the purpose of showing that a 'Lethal' UAV is both viable and desirable as an attack platform in the U.S. weapons arsenal. To accomplish this goal the reader is given a historical review of UAVs and their important missions, an in- depth overview of the Department of Defense's most capable UAVs, and a description of the sensors and payloads most likely to be used in the design of a Lethal UAV. Lastly, some possible Lethal UAV systems are presented along with an assessment on the feasibility of fielding such systems. While the primary objective of this thesis is to show that UAVs can be used to effectively locate and destroy mobile weapon systems, this document should also be used as a reference for those persons desiring an update on UAV technology and the DoD programs for testing and utilizing this technology.

Dymock, Ben R. "Urban wind turbines : a feasibility study." Thesis, London South Bank University, 2017. http://researchopen.lsbu.ac.uk/1864/.
Full textAbstract:
There is an existing body of research into noise, vibration and wind regime concerns associated with urban wind turbines demonstrating the detrimental effects of these topics on the energy yield potential and therefore financial worth of an installation. Much of the research has focused on wind regime assessment and optimum roof top placement via CFD modeling offering generalised guidelines showing a potential for wind power to contribute towards lowering London's CO2 emissions. Unfortunately, without benefiting from appropriate planning assessment, a number of early urban turbines failed and have risked irreversibly tarnishing the concept. Hitherto no studies have been specifically conducted on the urban potential of building integrated wind turbines. As integration is bespoke, typically determined by the architecture, it is unknown whether existing guidelines for roof mounted wind turbines could be directly applied. It is probable that each installation would merit its own assessment and analysis procedure. This study aims to investigate the differences between roof mounted and building integrated turbines in terms of assessment, operation and urban potential. In response to these differences it is intended to demonstrate how a successful installation can be achieved. Comparisons between two urban sites, one smaller, roof mounted HAWT and one larger, building integrated HAWT have been made via noise, vibration, CFD and atmospheric data recorded and analysed over two years to build a comprehensive understanding of the inherent urban issues. The prospect of successfully situating an urban turbine is complex in nature and considering the high installation costs and high level of design and engineering required to do so it is imperative that their energy yield provide a satisfactory return on investment and efficient supply of power without adversely impacting upon the surrounding environment or themselves. This study concludes that a multifaceted approach is necessary to achieve an efficient building integrated turbine, comprised of: (i) accurate local noise surveys to establish the local acoustic environment to inform acceptable turbine operating ranges, (ii) specific noise modeling of manufacturer provided data or, where none is available, acoustic testing of the proposed turbine across all applicable wind speed ranges, (iii) comprehensive vibration assessment, not only of the turbine tower/system but also of the turbine housing and any lower residential floors to ensure no natural frequencies will be excited and to prevent any vibration transmission via appropriate mounting, isolation or damping where necessary, (iv) the acquirement of site specific wind data to inform architectural design, turbine selection and placement. If monitoring at hub height is not possible it has been found that it may be acceptable to monitor in close proximity and then extrapolate the results using CFD analysis and wind profile methods, (v) CFD modeling of the surrounding topography, the turbine mount and/or enclosure. These areas are discussed with potential areas of noise and vibration control and turbine optimisation, specific to the case studies, investigated. Further to the aforementioned study an investigation into a new method of assessing noise and vibration levels associated with average anemometry recorded wind speeds has been presented so as to attain average levels per wind speed bin without being skewed by impulsive gusts.

organizations, audible signal manufacturers, and cities who
have knowledge of the devices, and responses were analyzed.
The devices were found to be feasible but only at certain
complex and confusing intersections. Twelve criteria for
the installation of the devices were developed as were
twelve criteria for the operation of the devices. Buzzers,
constant tones, bird calls, and voice signals were examined
by obtaining information from traffic engineers who had
experience with each sound. It was determined that
intermittent tones were the most effective for human
localization. For the most widely used devices, cost data
were developed for the products, installation, and maintenance. A partial listing of the U.S. and foreign
cities which have the devices was compiled along with a
partial listing of audible signal manufacturers. The
problems the visually impaired face as well as their
suggested solutions are listed. Topics for further study
include the use of hand-held devices which activate sound
signals at intersections and the development of tone schemes
for 4-leg and multi-leg intersections which are not north south

In recent years the idea of using partially restrained connections in building structures has become more practical and economical. Partially restrained connections resist moment and also allow rotation, therefore distributing the moments and stresses more evenly throughout the element. Combining this idea with steel joists, which are also quite common in construction, makes for shallower story heights and lower steel weights. This initial study analyzes partially restrained connections for both hot rolled shapes and steel joists using non-composite and composite construction. The designs are than compared with respect to complexity, practicality, serviceability and economics. The results of this study show that partially restrained joist connections are economically superior to comparable hot rolled member designs.Master of Science

Full textAbstract:
Accurate tumor tracking remains as a major challenge in radiation therapy. Large margins are added to the clinical target volume (CTV) to ensure the treatment of tumor in presence of patient setup uncertainty and that caused by intra-motion. Fiducial seeds and calypso markers are commonly implanted into the disease sites to further reduce the dose delivery error due to tumor motion. For more accurate dose delivery and improved patient comfort, the use of radioactive tracers in positron emission tomography (PET) as non-invasive tumor markers has been proposed - a concept called emission-guided radiation therapy (EGRT). Instead of using images obtained from a stand-alone PET scanner for treatment guidance, we mount a positron imaging system on a radiation therapy machine. Such an EGRT system is able to track the tumor in real time based on the lines of response (LOR) of the tumor positron events, and perform radiation therapy simultaneously. In this work, we illustrate the EGRT concept using computer simulations and propose a typical treatment scheme. EGRT's advantage on increased dose delivery accuracy is demonstrated using a pancreas tumor case and a lung tumor case without the setup margin and motion margin. The emission process is simulated by Geant4 Application for Tomographic Emission package and Linac dose delivery is simulated using a voxel-based Monte Carlo algorithm. The tumor tracking error can be controlled within 2 mm which indicates margins can be significantly reduced. The dose distributions show that the proposed EGRT can accurately deliver the prescribed dose to the CTV with much less margins. Although still in a preliminary research stage, EGRT has the potential to substantially reduce tumor location uncertainties and to greatly increase the performance of current radiation therapy.

Many bridges are destroyed or completely failed during floods due to excessive scouring around bridge piers and abutments. Safe bridge design is based on joint consideration of structural, hydraulic, and geotechnical aspects. This study is concerned with the investigation of various types of countermeasures against scouring at bridge sites. The design criteria for various countermeasures are reviewed in terms of hydraulic, hydrologic, constructional, and economical requirements. (Conditions of applicability of these countermeasures are evaluated and designed for different return periods of flow, and hydroeconomic analyses are performed for Esenbosa Bridge). Based on the evaluation of the results of hydroeconomic analyses, combinations of rock riprap and grout filled bags are found to be appropriate measures for piers and abutments against scouring whereas vegetation is observed to be applicable for bank protection.

Full textAbstract:
Singapore is a country that is currently highly dependent on import of oil and gas. In order to be able to shift into a more sustainable energy system, Singapore is investing in research regarding different technologies and systems so as to establish more sustainable energy solutions. Seeing how air-conditioning accounts for approximately 30 % of Singapore’s total energy consumption, a feasibility study is being conducted on whether an integrated system using a thermally active building system (TABS) and desiccant evaporative cooling system (DECS) can replace the air-conditioning system. The question which is to be discussed in this thesis is whether solar and wind power can be financially feasible in Singapore and if they can be utilized in order to power the integrated system. The approaching model consists of a financial feasibility study of the different technologies and a theoretical test-bedding, where the suitability of the technologies to power the TABS and DECS is tested. The financial feasibility is estimated by calculating the payback period and using the net present value method. A model designed in a digital modeling software is used for the test-bedding. Measurements from a local weather station are used for estimating the solar radiance and wind speeds in Singapore. The results show that solar PV panels could be feasible in Singapore but that technological improvements as well as governmental subsidies are needed in order to make it profitable enough to attract investors. As for wind power, the wind conditions are not favorable enough, in terms of wind speed and wind frequencies, for small wind turbines that currently exist on the market to be able generate enough electricity to make the investment somewhat feasible. Solar thermal collectors and solar PV are given certain conditions suitable for powering the TABS and DECS.

Full textAbstract:
This thesis involves a detailed study of steel-wood hybrid structures and their applications in construction industry. Hybrid structures combine benefits of dissimilar materials to overcome their individual limitations. Various advantages and challenges of steel-timber hybrid structures are presented. Benefits include increase in tensile capacity, seismic performance, fire resistance of the structure, and cost savings. Challenges with this type of hybrid structures originate from the differences in the properties of the materials used. Connection design may be more difficult as temperature and humidity variations have different effects on steel and timber. The hybrid materials can be integrated at component levels (hybrid slab/diaphragms, hybrid beams, hybrid columns, hybrid diagonals, hybrid post-tensioned joints) and/or at the building system levels (hybrid frames, hybrid system of steel frames and wood diaphragms, vertical mixed system and hybrid trusses). To elaborate on these types of hybridization and their advantages and challenges, case studies of steel-timber, concrete-timber and steel-concrete structures are provided. Despite the obvious advantages, today’s applications of wood-steel hybrid structures have been limited. Currently there are no material and design standards for hybrid wood-steel structures. For light structures, NAHB Research Center has developed a builder’s guide to hybrid wood and steel connection details. When combining steel and wood, designers should consider the advantages and limitation of each material and optimally utilize them. The literature review has highlighted the opportunity for wood-steel hybrid buildings and existing knowledge gaps. Another aim of this thesis is to investigate technical software packages and identify the pros and cons of each software pachage for modeling hybrid structures. The considered software packages are ANSYS, SAPWood, SeismoStruct and OpenSees Navigator. Software packages are evaluated interms of their ability to model linear and non linear materials; orthotropic and istotropic materials and composite materials. among the softwares ANSYS is found to be the most suitable for modelling hybird wood and steel structures. A case study of a hybird structure consisting of steel momet frame and wood shear wall is modeled with ANSYS. Static analysis is performed on the structure and it is observed that wood shear wall significantly reduce the lateral deflection of the system.

Full textAbstract:
A feasibility study into the use of UHF-EM transillumination measurements in geophysics is presented. The electrical properties and absorption rates of common crustal materials are examined with the goal of identifying specific conditions under which sufficient material penetration at UHF frequencies is available.A prototype 445 MHz continuous-wave transillumination instrument designed for underground use is described. Test surveys, with this instrument, were conducted at the Big Nickel Mine in Sudbury, Ontario, to obtain a number of through-rock absorption rates. Estimated effective resistivities of between 500 and 1500 ohm-metres are determined from the survey data.
Effective conductivities and permittivities from AC and DC electrical property measurements on geological samples from the mine site corroborate these transillumination survey results.
The results of the field surveys indicate that the UHF-EM transillumination technique is a feasible and useful geophysical method.

Full textAbstract:
The present work was conducted at Scania CV AB and has as main goal to produce a cast steel guideline. There is a great need to conduct a cast steel guideline, in order to help designers in their process to choose suitable materials and methods to produce lightweight components with higher performance. This work contains information related to mechanical properties, casting processes, castability, machinability, defect characterization, heat treatments, weldability and surface treatments of cast steels. This work was limited to cast steels which could be applied on two specific components of the truck, a bracket which is a structural component of chassis subjected to fatigue and a turbo manifold which is subjected to creep, oxidation, corrosion-, thermal- and mechanical- fatigue. A benchmark search was performed focused on these two components. A characterization of a cast stainless steel turbo manifold prototype was performed in the as-cast state, which included microstructural analyzes and hardness measurements. Besides this initial characterization, a set of heat treatments were conducted, in order to study the possibility to eliminate the initial grain boundary carbides. The main conclusions of this work are that cast steel has potential to be a material choice in many applications due to its wide range of properties. For structural parts, cast steel is advantageous compared with cast iron when for instance welding and high strength combined with high fracture toughness are requirements. For high temperature resistance components, cast steel or more precisely cast stainless steel, is advantageous for service at temperatures >750 ºC,besides its higher price. The annealing heat treatment followed by an aging treatment eliminated most of the grain boundary carbides and increase the hardness through a fine dispersion of carbides in matrix, which can also increase the creep resistance.Examensarbetet utfördes på Scania CV AB med främsta målet att utarbeta en vägledande guide för gjutstål. Det finns ett stort behov av att sammanställa en guideline för gjutstål, med syfte att hjälpa konstruktörer i deras process att välja lämpliga material och metoder för att producera lättviktskomponenter med högre prestanda. Arbetet innehåller information om mekaniska egenskaper, gjutningsprocesser, gjutbarhet, skärbarhet, defektkarakterisering, värmebehandlingar, svetsbarhet, ytbehandling och mycket annat gällande gjutstål. Detta arbete var begränsat till gjutstål som kan tillämpas för två specifika komponenter i lastbilen, en konsol som är en strukturell komponent i chassit som utsätts för utmattning och ett turbogrenrör vilket är en komponent som utsätts för högtemperaturcykler. En benchmark utfördes med fokus på dessa två komponenter. Slutligen gjordes en karakterisering av turbogrenrörsprototypen i rostfritt stål, i det gjutnatillståndet, vilket inkluderade mikroanalyser och hårdhetsmätningar. Förutom den förstakarakteriseringen, utfördes en uppsättning värmebehandlingar för att undersöka möjligheten att eliminera de initiala korngräns-karbiderna. De viktigaste slutsatserna av detta arbete är att gjutstål har potential att bli ett materialval i många applikationer på grund dess breda egenskaper. Konstruktionsdelar i gjutstål är fördelaktiga jämfört med gjutjärn, till exempel vid svetsning och när hög hållfasthet i kombination med hög brottseghet är nödvändigt. För högtemperaturs-komponenter är gjutstål, eller mer exakt, gjutna rostfria stål fördelaktiga för service vid temperaturer >750 ºC, med undantag för dess högre pris. Glödgningsvärmebehandling följt av åldringsbehandling eliminerar de flesta av korngräns-karbiderna och ökar hårdheten genom en fin dispersion av karbider i matrisen, vilket också kan öka krypmotståndet.

The effectiveness of cancer treatment is compromised by the need to reduce the uncertainties originating from a variety of factors including tumor volume delineation, patient setup, and irregular physiologic motion. In particular, effective yet practical tumor motion management remains a major challenge in current external beam radiation therapy. Many strategies such as motion encompassment, breath-hold techniques, and respiratory gating have been proposed in the literature and implemented clinically. These methods have shown success in certain situations with different limitations. With the advent of image guided radiation therapy, real-time tumor tracking methods have become popular in clinics to proactively address the challenge with on-board tumor localization. Nevertheless, such techniques rely on surrogate signals and have been reported vulnerable to errors. In this dissertation, EGRT is proposed as a new modality for effective and practical management strategy of cancer treatment uncertainties. One implementation of EGRT is to use PET emissions in real-time for direct tumor tracking during radiation delivery. Radiation beamlets are delivered along PET lines of response by a fast rotating ring therapy unit consisting of a linear accelerator and PET detectors. A complete treatment scheme with capabilities of accurate tumor tracking and dose planning is proposed to implement this EGRT concept. Simulation studies with physical phantom, 4D digital patient model, and clinical patient datasets are carefully designed to evaluate the feasibility and performance of EGRT. We show that with the capabilities of achieving both tumor tracking and sophisticated intensity modulation, EGRT has the potential to enable an effective implementation of 4D radiation therapy with true biological targeting and other advantages.

Detta examensarbete i maskinkonstruktion var en förstudie, som genomfördes på uppdrag av Atlas Copco Rock Drills AB i Örebro. Förstudien bygger på ett patenterat förslag till en ny design, som skulle göra det möjligt för Atlas Copcos gruvfordon att verka i låga underjordiska gruvmiljöer. Patentet byggde på en helt ny typ av konfiguration, som var avsedd att eventuellt implementeras på vissa gruvfordon. Den nya konfigurationen skulle göra det möjligt att vika och minska lastflakets storlek före dumpningsfasen. Syftet med denna studie var att använda olika tekniska metoder för att avgöra om denna nya flakidé skulle vara ett intressant alternativ för Atlas Copcos framtida generationer av gruvdumpers.The following Master Thesis project was carried out on behalf of Atlas Copco Rock Drills AB in Örebro, and in collaboration with KTH – Royal Institute of Technology, Stockholm. This project was a feasibility study based on a patented proposal for a new box design that would allow for Atlas Copco Minetruck vehicles to operate in low ceiling underground mine environments. This proposal was based in an entirely new box configuration with the potential of being introduced at Minetruck vehicles. The configuration of this box would allow it to fold and reduce its size prior to the dumping phase of the material. The aim of this study was to use various engineering methods in order to determine whether this new box idea would be an interesting Minetruck box alternative for the future vehicle product range of Atlas Copco.

Full textAbstract:
Reducing environmental and health impacts of using fossil fuel are the main concerns in the majority of countries which resulted in shifting from the use of fossil fuels (e.g., coal, oil, natural gas) to renewable energy (e.g., solar, wind, water) for electricity generation. The use of renewable energy sources is becoming more popular in the majority of Middle Eastern countries, particularly in Oman. In Oman, the use of renewable energy to produce electricity is rapidly growing considering that renewable energy will reduce the use of fossil fuel as the major source of energy. Hydropower is an important renewable energy resource globally. However, the feasibly of a hydropower plant in Oman has not been investigated. Therefore, the purpose of this project was to determine the feasibility of hydropower which can be installed in the Wadi Dayqah dam in Oman. The objectives are to explore the potential power to be harvested by hydropower, to assess financial saving and cost analysis and to investigate the environmental impact of hydropower in Oman.
The RETScreen expert was used to assess the feasibility of a hydropower system and to recommend the possibility of installing the system in the Wadi Dayqah Dam in Oman. The RETScreen expert is a Clean Energy Management Software developed by the Government of Canada which is a free-of-charge decision support software for pre-feasibility or feasibility analysis and also ongoing energy efficiency performance analysis.
In this project, two cases have been analysed. For the case one (the design flow was 0.3 m3/s, and installed capacity was 110 kW), the RETScreen analysis showed estimated cost 338,000 AUD, annual savings and revenue 57,165 AUD and Gross Annual GHG reduction 605.3 tCO2/year. For the case two (the design flow was 13 m3/s, and installed capacity was 5 MW), the RETScreen analysis demonstrated the estimated cost 6,204,000 AUD, annual savings and revenue 1,802,747 AUD and Gross Annual GHG reduction 19,090.1 tCO2/year.
Overall, this project indicated that the use of the hydropower system in the Wadi Dayqah Dam in Oman is viable regarding technical, economic, and environmental aspects.

A methodology was developed for determining the economic feasibility of a wood products industrial park. The methodology consists of twelve steps that address the goals of park owners, the feasibility of secondary manufacturing alternatives, the feasibility of the development corporation, and the financial areas needing management attention. Prerequisites to the financial analysis include market and technical analyses. Community impact analysis was also acknowledged as an important component of an overall feasibility analysis.
A case study was performed that consisted of an economic feasibility analysis for a wood products industrial park in Southwest Virginia. The case study assumed private ownership and found that the best mix of park tenants included: an edge-glued dimension panel manufacturer, a solid dimension lumber manufacturer, a custom millwork manufacturer, and a pallet manufacturer. Primary manufacturing and marketing services were included in the preferred park formation as subsidiaries of the park development corporation. The park was predicted to have a strong positive impact on the regional economy.

Full textAbstract:
The following report is conducted as a feasibility study, aimed to objectively uncover the advantages and challenges of increasing the amount of small scale solar power in Sri Lanka. The demand for electricity in Sri Lanka has been steadily increasing the last few years and there is an urgent need to find new ways of generating electricity. To not further increase the already high dependency of foreign oil and to decrease the impact on the environment, a transition from traditional combustion of fossil fuel to new renewable energy is required. The report shows that there exists substantial potential for generating solar energy in Sri Lanka. Calculations show that an investment in a photovoltaic system can be economically favourable and that the investment often is paid back within a few years. Current regulations and electricity pricing increases the economic incitement for high electricity consumers to invest in small scale solar power. Furthermore, the report demonstrates that there are likely no technical obstacles of increasing small scale solar power at this period. In contrary, the report shows that small scale solar power in general decreases line losses, voltage drops, and the peak demand of electricity. At present, it is probably not the lack of economic incitement but rather socio-economic factors that limit the development of small scale solar power. Sri Lanka is still a relatively poor country and the long years of civil war have prevented development and wealth. Lack of funds and a high ratio of low-income earners are probably the main reason for the slow development

Full textAbstract:
Dysarthria describes the impaired speech intelligibility caused by weakness of muscles involved in speech following stroke. This is a common consequence of stroke and can have a detrimental impact on self-confidence leading to social isolation for many. There is limited evidence for dysarthria intervention but we know that research into speech difficulties after stroke is a priority for stroke survivors. An online speech rehabilitation programme was developed, ReaDySpeech, with the potential to offer improved quality of independent practice, increased intensity of practice and the ability to record interaction. The research presented in this thesis aimed to systematically examine the existing evidence base, to carry out some preliminary acceptability work on ReaDySpeech, and implement a feasibility trial. The initial study was a Cochrane systematic review of the effectiveness of interventions for people with non-progressive dysarthria after stroke or other adult-acquired brain injury. This found insufficient evidence to know whether dysarthria intervention is effective or not. This led to a study of early acceptability work for ReaDySpeech and whether there were any technical barriers to use. This found no significant technical barriers other than lack of Wi-Fi and it was acceptable to participants and therapists. This enabled a progression to a feasibility trial following amendments and improvements to the protocol and ReaDySpeech itself. The feasibility trial found recruitment, retention and the intervention were all feasible to carry out during a trial. Further in-depth consideration of the findings indicates more work is needed to widen recruitment and to develop the intervention, comparator and methodology of a future trial for this to be a success with valid clinical implications. This thesis reports this body of work and discusses potential future directions for dysarthria research.

Full textAbstract:
Zebrafish are becoming an increasingly popular model organism in which to model diseases with a genetic component. Their use is hindered however, by the lack of an efficient, reliable, stable and cost-effective method to carry out reverse genetics and model diseases which arise from a loss of function of a gene. RNAi is a method of post-transcriptional gene regulation and has been widely manipulated in other systems to knockdown genes at will. This thesis therefore looks at the feasibility of vector-mediated RNAi in zebrafish by attempting to knockdown green fluorescent protein (GFP) and the Parkinson‟s disease-associated gene PTEN Induced Kinase 1 (PINK1).Initial results in HEK 293 cells and in G0 animals were encouraging, however low expression of the self-reporting vector made the identification of transgenic animals difficult. To improve expression levels the vector was modified to contain a Gal4-VP16/UAS amplification cassette. Inclusion of this cassette led to increased expression and knockdown capabilities of the vector in HEK 293 cells and led to the successful identification of transgenic zebrafish. Despite high level expression however, no knockdown of GFP or PINK1 was detected in transgenic zebrafish larvae expressing the RNAi vectors out to 5 dpf. This lack of knockdown was shown to be despite the expression of the main components of the RNAi pathway and the production of customised miRNAs throughout development and across tissues. Interestingly however, in adult transgenic zebrafish 50% knockdown of PINK1 was detected in brains expressing two independent PINK1 miRNAs compared to the control miRNA and wild type zebrafish brains. This knockdown coincided with increased transcript expression of the RNAi components and increased production of customised mature miRNA in the brain compared to embryos.In an attempt to improve vector-mediated RNAi in zebrafish, the effect of over-expression of components of the RNAi machinery, including Argonaute 2, Dicer, Drosha and Exportin 5 was assessed in zebrafish cells. Of these, only over-expression of Argonaute 2 improved knockdown in HEK 293 cells and resulted in moderate knockdown in two independent zebrafish cell lines, PAC.2 and ZFL cells. This improvement in knockdown was shown to be a result of the RNase activity of Argonaute 2 as mutation of this domain abrogated the effect of Argonaute 2 over-expression. Despite the encouraging results in zebrafish cell lines, injection of Argonaute 2 mRNA into transgenic zebrafish failed to produce knockdown, suggesting perhaps, that in zebrafish embryos other factors apart from Argonaute 2 are also limitingGiven the difficulties of vector-mediated RNAi in zebrafish, this technology is at present not a feasible approach to knocking down genes in zebrafish, at least not to an extent as to model complete loss of gene function.

Although wood is widely used as a construction material, it is mostly limited to low and mid-rise residential construction, partially due to fire code restrictions. This limitation can be overcome by considering hybrid systems which combine wood with non-combustible materials.
This research presents an innovative wood-concrete hybrid system, suitable for tall buildings, where a concrete frame with slabs at every third story provides fire separation as well as stiffness and strength to resist gravity and lateral loads. The intermediate stories including their floors are constructed using light-frame wood modules. This approach reduces the environmental footprint of the building, reduces the building weight and therefore the seismic demand on connections and foundation, and speeds up the construction process.
For a novel system, numerical modeling is crucial to predicting its structural response to static and dynamic loading. This thesis studies the structural feasibility of the system by developing finite element models and assessing the structural behavior at the component and system levels when subjected to earthquake and wind loads. Nonlinear analyses are performed considering material and geometric nonlinearity using multiple ground motions to estimate the structure’s inter-story drift and base shear. The results demonstrate the feasibility of the proposed wood-concrete hybrid system for tall buildings in high seismic zones.Applied Science, Faculty of

Full textAbstract:
The fluxgate electric field meter is a new solid-state instrument capable of measuring slowly varying electric fields equally well in an insulating or conducting medium with high resolution. The field meter determines the strength of an electric field by measuring the potential difference between two insulated electrodes immersed in the electric field. The electrode insulation is important because it eliminates the contact potential noise between the conductive material of the electrode and a conductive medium. The capacitance of the insulated electrodes is of the order of 10pF; therefore measurement of the potential difference between the electrodes requires an electrometer with extremely low bias current and high input resistance. A novel electrometer was concieved and designed to accomplish this task. The new electrometer is a solid-state analogue of the vibrating-capacitor electrometer and is claimed to have zero bias current. MOS capacitors are substituted for the vibrating capacitor. The noise level for the crude, proof-of-concept electrometer was 220μVHz[sup -1/2] at 1Hz. This noise level is only 20 dB worse than the best commerical device I could locate. A crude, proof-of-concept electric field meter constructed with the electrometer had a high frequency cutoff of 150Hz and low frequency cutoff of 100μHz. Possible applications of the fluxgate electric field meter include measurement of atmospheric and interplanetary electric fields, measurement of static charge buildup, and geophysical surveys.Science, Faculty of

Full textAbstract:
Rising awareness in the need for environmental protection has brought into question the adequacy of conventional hazardous waste treatment operations. Regulatory standards are increasingly strict, and there is growing concern over the safety of incineration facilities. This research project examines the technoeconomic potential of thermal plasma technology in this context.Adaptive Plasma-Assisted Incineration (APAI) is a novel concept for secondary gas treatment in hazardous waste incineration. As an energy source for waste destruction, a thermal plasma can provide conditions far higher in temperature and in reactivity than those obtained using a combustion flame. Thus, the plasma is more effective at destroying hazardous materials, albeit at a higher cost.
APAI features a thermal plasma afterburner with continual on-line optical monitoring of the gas product and feedback optimization of the plasma conditions. This approach allows complete destruction of persistent organic compounds and cost-effective response to feed load variations. The process supplements conventional incineration techniques with the effectiveness and flexibility of thermal plasma treatment. The main objectives are to reduce the risk of harmful emissions during hazardous waste incineration and to facilitate compliance with new environmental regulations.
In this project, the technical feasibility of APAI was demonstrated experimentally using a laboratory-scale plasma afterburner model. The work focused on the development of a spectroscopic monitoring procedure and on the application of optimization techniques for cost-effective operation of the model system. The techno-economic potential and limitations of APAI were addressed in a conceptual study. Preliminary designs and cost estimates were developed for specific applications. The costs of plasma-assisted and conventional methods were compared for contaminated soil remediation (by incineration and desorption) and for organic liquid waste destruction. Economically, APAI appears uncompetitive at the present time. However, it remains a promising alternative in view of ongoing environmental policy changes and developments in plasma technology.

The study may suggest and lead to policy and actions to minimize of even eliminate energy losses, and can guide us to zero emission cities and naval bases. This has the benefits of assisting ecology and petroleumbased fuel economy. During this study, not only an energy balance is estimated, but also the economic feasibility of the project is examined, in order to achieve a reasonable balance of initial and maintenance cost of the renewable energy sources and fuel economy. Following a comprehensive review of available sources, the study starts with an area selection. The geographical area selected is a large island off the main metropolitan region of Greece. It presents several challenges, mainly due to its size, diverse energy needs including a major naval base, and a widely fluctuating population with varying energy needs. These needs are analyzed along with the energy sources available in the area. A variety of optimization programs is selected offering several advantages and disadvantages. A set of parametric runs is conducted in order to reveal the most promising solutions from both a technical and an economic sense.

Due to external factors such as economic conditions and business circle, the public finance has been more and more tightened; in order to guarantee that limited resources in the country can be distributed appropriately, and to improve the benefit of public construction, the authorities established relevant regulations of the public construction feasibility study (anticipative evaluation) on the time limit, division of authority & responsibility, work matters and achievements, etc. However, since the Public Construction Committee, Executive Yuan has not integrated various regulations on feasibility study of public construction, the merits and functions of feasibility study seemed indeterminate, leading to that the government experienced various problems when doing feasibility study. In order to facilitate the feasibility study of large-scale public construction, this research applies the Project Management Body of Knowledge (PMBOK) developed by the Project Management Institute (PMI, U.S.A), along with the Taipei City Government’s experiences, trying to conduct the management model of public construction feasibility study. This research concerns five primary processes including initialing, planning, purchasing, contract-administrating, closing. Moreover, it clearly portrays the essentials in feasibility study and organizes relevant working forms, in order to improve the public project benefit and guarantee that the public construction can be executed successfully.
