Abstract:

This report is the result of a conducted Minor Field Study (MFS), to the greatestextent funded by the Swedish International Development Cooperation Agency(SIDA), in an attempt to design a system for evaluating smaller solar power systems indeveloping countries. The study was to the greater part conducted in Nairobi, Kenyain close collaboration with the University of Nairobi. The aim was to develop asystem that would use easily available components and keep the costs to a minimum,yet deliver adequate performance. The system would measure certain parameters of asolar power system and also relevant environmental data in order to evaluate theperformance of the system. Due to the specific competence of the collaboratinggroup at the University of Nairobi, a Kinetis Freescale K64-microcontroller with anARM-Cortex processor was selected as the core of the design. Components wereselected, schematics were drawn, a circuit board was designed and manufactured andsoftware was written. After 12 weeks a somewhat satisfying proof-of-concept wasreached at the end of the field study in Kenya. The project however proved howdifficult it is to go from first idea to a functional proof-of-concept during a limitedtimeframe, and also in an East-African country. The final proof-of-concept was testedat Mpala Research Centre in Kenya and despite containing some flaws proved that itwould indeed be possible to design a working system on the principles discussed inthis report. The system is open-source, so anyone may use and modify it.

Haule, Henrick Joseph. "Evaluation of Traffic Incident Timeline to Quantify the Performance of Incident Management Strategies." UNF Digital Commons, 2018. https://digitalcommons.unf.edu/etd/791.

Abstract:

Transportation agencies are introducing new strategies and techniques that will improve traffic incident management. Apart from other indicators, agencies measure the performance of the strategies by evaluating the incidents timeline. An effective strategy has to reduce the length of the incident timeline. An incident timeline comprises various stages in the incident management procedure, starting when the incident was detected, and ending when there is the recovery of normal traffic conditions. This thesis addresses three issues that are related to the traffic incident timeline and the incident management strategies. First, co-location of responding agencies has not been investigated as other incident management measures. Co-location of incident responders affects the incident timeline, but there is a scarcity of literature on the magnitude of the effects. Evaluation of the co-location strategy is reflected by the response and verification durations because its effectiveness relies on improving communication between agencies. Investigation of the response and verification duration of incidents, before and after operations of a co-located Traffic Management Center (TMC) is done by using hazard-based models. Results indicate that the incident type, percentage of the lane closure, number of responders, incident severity, detection methods, and day-of-the-week influence the verification duration for both the before- and after- period. Similarly, incident type, lane closure, number of responders, incident severity, time-of-the-day, and detection method influence the response duration for both study periods. The before and after comparison shows significant improvements in the response duration due to co-location of incident response agencies. Second, the incident clearance duration may not necessarily reflect how different types of incidents and various factors affect traffic conditions. The duration at which the incident influences traffic conditions could vary – shorter than the incident duration for some incidents and longer for others. This study introduces a performance measure called incident impact duration and demonstrates a method that was used for estimating it. Also, this study investigated the effects of using incident impact duration compared to the traditionally incident clearance duration in incident modeling. Using hazard-based models, the study analyzed factors that affect the estimated incident impact duration and the incident clearance duration. Results indicate that incident detection methods, the number of responders, Traffic Management Center (TMC) operations, traffic conditions, towing and emergency services influence the duration of an incident. Third, elements of the incident timeline before the clearance duration have been overlooked as factors that influence the clearance duration. Incident elements before the clearance duration include verification time, dispatch duration, and the travel time of responders to the incident scene. This study investigated the influence of incident timeline elements before clearance on the extent of the clearance duration. Also, this study analyzed the impact of other spatial and temporal attributes on the clearance duration. The analysis used a Cox regression model that is estimated using the Least Absolute Shrinkage and Selection Operator (LASSO) penalization method. LASSO enables variable selection from incidents data with a high number of covariates by automatically and simultaneously selecting variables and estimating the coefficients. Results suggest that verification duration, response travel duration, the percentage of lane closure, incident type, the severity of an incident, detection method, and crash location influence the clearance duration.

Vargas, Vidal Velez. "Bridge Deck Cracking Investigation and Repair." UNF Digital Commons, 2012. http://digitalcommons.unf.edu/etd/401.

Abstract:

The focus of this study is to investigate the cracking of concrete bridge decks and the sealants used in repairing transverse cracks. Cracking could occur in both hardened mature concrete and early age concrete. Several factors affect concrete cracking, such as age-dependent material properties, thermal- and moisture-related stresses and strains, material viscoelastic behavior, restraints, concrete expansion and contraction, casting sequence, formwork, material characteristics, and environmental exposure. The causes of early age cracking are primarily attributed to effects such as plastic shrinkage, temperature effects, autogenous shrinkage, and drying shrinkage. This deck cracking could greatly reduce durability, lead to a loss of functionality, loss of stiffness, and ultimately the loss of structural safety. The study investigates the deck cracking in general and also the transverse cracks developed in hardened concrete at early ages before service loads application. Both experimental and analytical investigations were performed. The experimental study included testing of 9 reinforced concrete slab specimens (18”x 48”x 5.5”). Cracks were induced in the slabs with different crack widths and lengths, sealed with 4 different materials of sealants, and tested under static loading. The study also included tensile testing of dry hardened samples of sealants. In addition, field application was performed on a bridge, where transverse deck cracks were sealed using 4 different sealant materials; cores were taken and tested according to ASTM-C496. The results of the testing showed that the 3-part HMWM was the best performing sealer for cracks between 0.01 and 0.019 inches of width with the epoxy sealer performing the best for cracks wider than 0.02 inches.

Chawla, Lovelesh. "Use of IBM Collaborative Lifecycle Management Solution to Demonstrate Traceability for Small, Real-World Software Development Project." UNF Digital Commons, 2015. http://digitalcommons.unf.edu/etd/606.

Full text

Abstract:

The Standish Group Study of 1994 showed that 53 percent of software projects failed outright and another 31 percent were challenged by extreme budget and/or time overrun. Since then different responses to the high rate of software project failures have been proposed. SEI’s CMMI, the ISO’s 9001:2000 for software development, and the IEEE’s JSTD-016 are some examples of such responses. Traceability is the one common feature that these software development standards impose. Over the last decade, software and system engineering communities have been researching subjects such as developing more sophisticated tooling, applying information retrieval techniques capable of semi-automating the trace creation and maintenance process, developing new trace query languages and visualization techniques that use trace links, applying traceability in specific domains such as Model Driven Development, product line systems and agile project environment. These efforts have not been in vain. The 2012 CHAOS results show an increase in project success rate of 39% (delivered on time, on budget, with required features and functions), and a decrease of 18% in the number of failures (cancelled prior to completion or delivered and never used). Since research has shown traceability can improve a project’s success rate, the main purpose of this thesis is to demonstrate traceability for a small, real-world software development project using IBM Collaborative Lifecycle Management. The objective of this research was fulfilled since the case study of traceability was described in detail as applied to the design and development of the Value Adjustment Board Project (VAB) of City of Jacksonville using the scrum development approach within the IBM Rational Collaborative Lifecycle Management Solution. The results may benefit researchers and practitioners who are looking for evidence to use the IBM CLM solution to trace artifacts in a small project.

Abstract:

The purpose of this study was to examine conservation, livelihoods, and the role of tourism. The village of Sukau in the Kinabatangan District of Sabah, Malaysia, served as a case study. The vital importance of the Lower Kinabatangan in wildlife conservation, coupled with the tourism potential of the region, underpinned the creation of the Kinabatangan Wildlife Sanctuary in 2005. The 26,000 hectare sanctuary is fragmented in nature and surrounded by palm oil plantations. Still, with the protection of these fragmented forested areas, Sukau has evolved into the ‘hub’ of tourism in the Lower Kinabatangan. The majority of visitors come to Sukau for the opportunity to view the flagship species of the Kinabatangan Wildlife Sanctuary (orang-utan, Bornean pygmy elephant, proboscis monkey, and hornbills) in the wild. Many of the local villagers own land which is still forested and serves as important ecological links between the fragmented protected areas. However many of the villagers plan to use their lands for smallholder palm oil farming in the future. This will further fragment the forested areas of the Wildlife Sanctuary, and will have severe implications for nature conservation and tourism in Sukau. The Sabah Tourism Master Plan (1996) stresses that for the tourism-conservation linkage to be effective in Sukau, the local community must benefit from tourism. If the locals of Sukau are able to depend on tourism as a livelihood option, then perhaps the forested areas of the Wildlife Sanctuary will not be further fragmented in the near future. This study will attempt to answer whether tourism is an effective alternative livelihood source for the locals of Sukau. Predominantly qualitative research methods were used for this study. These included semi-structured interviews with the local villagers of Sukau, and informal interviews with key informants in the area. Structured questionnaires and interviews were also undertaken with lodges in and near the village. The information gathered from these sources was further strengthened by my own personal and participatory observations. In 2006, 10 per cent of the population of Sukau, and 23 per cent of the estimated total workforce were directly employed in tourism. Results indicate that having tourism as a livelihood option has made the villagers more motivated to protect their environment. Yet the locals of Sukau disagree that their community benefits sufficiently from tourism, and smallholder palm oil farming is viewed as the more lucrative livelihood option. The current financial crisis (2008-9) has complicated the likely contribution of tourism to livelihoods and conservation in the future. Nevertheless it is likely that both the palm oil and tourism industries will recover from the economic downturn, and consequently they will both continue to be future livelihood options for the villagers of Sukau. Therefore steps should be made to improve both industries for the benefit of livelihoods and nature conservation in Sukau. There are a number of potential ways in which tourism could be improved in Sukau to bring more benefits to the locals. If these suggested improvements occur, then the effectiveness of tourism as an alternative livelihood source for the locals of Sukau will be enhanced.

Abstract:

Web page loading time is one of the critical challenges on the Internet. Thistopic attracts more researchers as it largely reflects the user satisfaction.A web page resources typically consists of Hyper Text Markup Language(HTML), Cascading Style-Sheet (CSS), JavaScript (JS), media files, etc.As the complexity of the web page increases, the size of files fetched fromserver also increases which causes delay in transmitting, loading, parsing andrendering the web page.The web page is not rendered until HTML, CSS and JS files are loadedand parsed. Not all such files are needed to be rendered for the first page.Optimizing and loading only critical les required for the first page, can considerablyreduce time taken to load the web page. After the first page isrendered, the rest of the files can be loaded and executed. In this thesis,we focus on improving the time taken for First Meaningful Paint(FMP) ofwebsite by loading the critical files initially. We used Design Science Research(DSR) methodology and created a PhantomJS application, to identifyand segregate used and unused CSS for the first meaningful paint of the webpage. We also analyzed script files to load only critical files required forFMP and the rest later. We evaluated our experiment by studying a case onAxis Communications AB and measured its website's performance to find ifour experiment reduced FMP time. It showed improvement in time takenfor FMP from 1284ms to 372.6ms. Based on the results, we suggest to webdevelopers to separate and load the files required for FMP and load the restof the files needed for the website later, so that the first page is renderedquickly.

Kitali, Angela E. "Bayesian Approach on Quantifying the Safety Effects of Pedestrian Countdown Signals to Drivers." UNF Digital Commons, 2017. http://digitalcommons.unf.edu/etd/729.

Full text

Abstract:

Pedestrian countdown signals (PCSs) are viable traffic control devices that assist pedestrians in crossing intersections safely. Despite the fact that PCSs are meant for pedestrians, they also have an impact on drivers’ behavior at intersections. This study focuses on the evaluation of the safety effectiveness of PCSs to drivers in the cities of Jacksonville and Gainesville, Florida. The study employs two Bayesian approaches, before-and-after empirical Bayes (EB) and full Bayes (FB) with a comparison group, to quantify the safety impacts of PCSs to drivers. Specifically, crash modification factors (CMFs), which are estimated using the aforementioned two methods, were used to evaluate the safety effects of PCSs to drivers. Apart from establishing CMFs, crash modification functions (CMFunctions) were also developed to observe the relationship between CMFs and traffic volume. The CMFs were established for distinctive categories of crashes based on crash type (rear-end and angle collisions) and severity level (total, fatal and injury (FI), and property damage only (PDO) collisions). The CMFs findings, using the EB approach indicated that installing PCSs result in a significant improvement of driver’s safety, at a 95% confidence interval (CI), by a 8.8% reduction in total crashes, a 8.0% reduction in rear-end crashes, and a 7.1% reduction in PDO crashes. In addition, FI crashes and angle crashes were observed to be reduced by 4.8%, whereas a 4.6% reduction in angle crashes was observed. In the case of the FB approach, PCSs were observed to be effective and significant, at a 95% Bayesian credible interval (BCI), for a total (Mean = 0.894, 95% BCI (0.828, 0.911)), PDO (Mean = 0.908, 95% BCI (0.838, 0.953)), and rear-end (Mean = 0.920, 95% BCI (0.842, 0.942)) crashes. The results of two crash categories such as FI (Mean = 0.957, 95% BCI (0.886, 1. 020)) and angle (Mean = 0.969, 95% BCI (0.931, 1.022)) crashes are less than one but are not significant at the 95 % BCI. Also, discussed in this study are the CMFunctions, showing the relationship between the developed CMFs and total entering traffic volume, obtained by combining the total traffic on the major and the minor approaches. In addition, the CMFunctions developed using the FB indicated the relationship between the estimated CMFs with the post-treatment year. The CMFunctions developed in this study clearly show that the treatment effectiveness varies considerably with post-treatment time and traffic volume. Moreover, using the FB methodology, the results suggest the treatment effectiveness increased over time in the post-treatment years for the crash categories with two important indicators of effectiveness, i.e., total and PDO, and rear-end crashes. Nevertheless, the treatment effectiveness on rear-end crashes is observed to decline with post-treatment time, although the base value is still less than one for all the three years. In summary, the results suggest the usefulness of PCSs for drivers.

Karaer, Alican. "Effects of Traffic Incidents on Adjacent Facilities and Alternative Re-Routing Strategies." UNF Digital Commons, 2018. https://digitalcommons.unf.edu/etd/781.

Full text

Abstract:

This study presents an analysis of detour operations as a concept of congestion management. Since a large portion of traffic delay emanates from traffic incidents, the goal of the study was to alleviate incident-induced impacts on freeways by diverting congested traffic on to adjacent roadway facilities. To balance the demand between freeway and arterial systems, optimization was required through Integrated Corridor Management (ICM). This thesis examines the justification and optimization of dynamic traffic routing strategies. Previous studies have justified detour operations based solely on traffic simulation results. This study quantifies the impacts from freeway incidents on a parallel arterial roadway using a data-driven signal processing technique, with operating speeds adopted as a performance measure. Results show that rerouting traffic to an adjacent arterial road, due to a freeway incident, can mitigate the mobility of the corridor with a probability of up to 88% depending on the type of incident and occurrence time. Results also indicate that diverting traffic during off-peak hours, especially for minor incidents, provides minimal mobility benefits. A secondary focus of this study explored the optimum dynamic traffic diversion, to an adjacent arterial roadway, from incident-induced freeway congestion to better utilize the freeway’s available corridor capacity. VISSIM, a microsimulation tool, was employed to simulate a freeway incident and measure the performance of detour operations. A 23 full factorial central composite design was used to establish a relationship between the performance of the detour operation and three control factors: incident duration, diversion rate, and demand level. The resulting regression equation predicts the corridor delay with over 83% accuracy. The findings of this study can potentially serve as a building block in the understanding and development of future ICM systems and incident management plans.

Castilla, Dalila. "A Hybrid Approach Using RUP and Scrum as a Software Development Strategy." UNF Digital Commons, 2014. http://digitalcommons.unf.edu/etd/514.

Full text

Abstract:

According to some researchers, a hybrid approach can help optimize the software development lifecycle by combining two or more methodologies. RUP and Scrum are two methodologies that successfully complement each other to improve the software development process. However, the literature has shown only few case studies on exactly how organizations are successfully applying this hybrid methodology and the benefits and issues found during the process. To help fill this literature gap, the main purpose of this thesis is to describe the development of the Lobbyist Registration and Tracking System for the City of Jacksonville case study where a hybrid approach, that integrates RUP and Scrum, was implemented to develop a major application to provide additional empirical evidence and enrich the knowledge in this under-investigated field. The objective of this research was fulfilled since the case study was described in detail with the specific processes implemented using RUP and Scrum within the context of the IBM Rational Collaborative Lifecycle Management Solution. The results may help researchers and practitioners who are looking for evidence about conducting a hybrid approach. However, more case studies that successfully combine RUP and Scrum need to be developed in order to have enough empirical evidence.

Full text

Abstract:

In recent years the use of carbon fiber reinforcing polymers (CFRP) to repair damaged structural components has become more accepted and practiced. However, the current reference for designing FRP systems to repair and strengthen reinforced concrete (RC) and prestressed concrete (PSC) girders has limitations. Similarly, very few resources address solutions for the debonding problem associated with CFRP laminates or the use of CFRP laminates to repair structural members with pre-existing damage. The included experimental program consists of testing both RC and PSC girders with simulated lateral damage and CFRP repairs. A total of 34 RC beams were statically tested under a 4-point loading until failure and had cross-section dimensions of 5” x 10” (14cm x 25.4cm), were 8’ long (2.44m), and were reinforced with either #3 or #4 mild steel rebar. 13 PSC girders having cross-section dimensions representing a half-scaled AASHTO type II shape, were 20’ long (6.1m), and were prestressed with five 7/16” (11.1mm) diameter low-lax 7-wire strands. Ten of the PSC girders were statically loaded until failure under a 4-point testing setup, but 3 PSC girders were dynamically tested under fatigue loading using a 3-point arrangement. Different configurations of CFRP laminates, number and spacing of CFRP transverse U-wraps, and amount of longitudinal CFRP layers are studied. The results present the flexural behavior of all specimen including load-deflection characteristics, strain characteristics, and modes of failure. Ultimately, results are used to recommend important considerations, needed criteria, and proper design procedures for a safe and optimized CFRP repair configuration.

Full text

Abstract:

The goal of this master thesis was to develop a method for real-time classification of market trading data at the Foreign Exchange (FX) department at the Skandinaviska Enskilda Bank (SEB). The characteristics in the market data sets were analyzed using Principal Component Analysis (PCA). The analysis showed that the principal component subspaces for two different types of market data, normal and abnormal, for the EUR/USD instrument where significantly different. The result from the PCA naturally led into the construction of a Single-class detector, for detecting if quote updates were normal or abnormal based on training data. The market data sets were shown to possess multicollinear characteristics, resulting in low-rank properties of the covariance matrices. To overcome this problem the solution was to transform the data using PCA, resulting in full-rank properties of the covariance matrices of the transformed data. This vital step made it possible to classify quote updates for the EUR/USD instrument. The project resulted in a classification algorithm which is able to successfully classify if a quote update is normal or abnormal with respect to training data in real-time. The algorithm is versatile in the sense that it can be implemented on any market for any currency pair, and can easily be extended to classify the relative behaviour between several currency pairs in real-time.

Abstract:

Innovation is essential for the growth and survival of an organisation. Although innovation is viewed as important, managers generally have a vague sense of their company’s innovativeness and which tools that are available to evaluate their capability to innovate. Previous research state that scorecard-based innovation audit tools do have merit in evaluating an organisations capability to innovate, but that there are a number of weaknesses. Problems are raised concerning three areas, the dimensions of which the scorecard is based on, the respondent that is conducting the innovation audit, and the Likert scale which a majority of innovation audit tools are using. Problems in these areas affect the reliability and validity of the tool. The purpose of this study is to investigate the current innovation audit practices by examining employee’s perception of the tool. Further the purpose is to, with the help of literature and qualitative research, propose areas of improvements and bring forth ideas that should be taken into consideration in future development of innovation audit tools. The study is performed as a qualitative study with an iterative approach. Interviews were conducted with nine parties of interest, and the empirical data has been analysed through a thematic analysis. The result show that an organisation’s capability to innovate is hard to measure and that there exists scepticism whether or not an innovation audit tool does manage to do this. Further, problems exist within the identified areas of an innovation audit tool. These problems affect the validity and reliability of the tool. A problem is how the respondent of the innovation audit tool interpret the statements or questions, and how they interpret the scale. Another problem is the self-interest that may exist, depending on who is participating in the audit. Ideas to minimise these problems are brought forward and discussed in order to increase the validity and reliability of the innovation audit tool.
Innovation är en förutsättning för en organisations tillväxt och överlevnad. Trots att innovation ses som en viktig förutsättning så har chefer i allmänhet en otydlig bild av deras organisations förmåga att skapa innovation och vilka verktyg som finns tillgängliga för att utvärdera denna förmåga. Forskning visar att scorekort baserade verktyg kan ge värdefulla insikter då en organisations förmåga att skapa innovation utreds. Forskningen visar vidare att det finns svagheter vid den här typen av utvärderingar. Tre problemområden har identifierats. De dimensioner som det scorekort baserade verktyget är baserade på, respondenten som svarar på utvärderingen, samt Likert-skalan som en majoritet av utvärderingsverktygen använder. Problem inom dessa områden påverkar verktygets pålitlighet och giltighet. Syftet med denna studie är att undersöka de nuvarande verktyg för utvärdering av förmågan att skapa innovation genom att granska medarbetares uppfattning om verktyget. Vidare är syftet att med hjälp av litteratur och kvalitativ forskning föreslå förbättringsområden och föra fram idéer som bör beaktas vid framtida utveckling av verktyg för att utvärdera förmågan att skapa innovation. Studien utfördes som en kvalitativ forskning med ett iterativt tillvägagångssätt. Intervjuer genomfördes med nio parter av intresse, och empiriska data har analyserats genom en tematisk analys. Resultatet visar att en organisations förmåga att skapa innovation är svår att mäta och att det finns skepsis huruvida ett verktyg för att mäta förmågan att skapa innovation lyckas med detta eller inte. Vidare existerar problem inom de identifierade områdena av utvärderingsverktygen. Dessa problem påverkar verktygets pålitlighet och giltighet. Ett problem är hur respondenten av utvärderingsverktyget tolkar påståendena eller frågorna och hur de tolkar Likert-skalan. Ett annat problem är det självintresse som kan existera, beroende på vem som deltar i utvärderingen. Idéer för att minimera dessa problem framförs och diskuteras för att öka pålitligheten och giltigheten i verktyget.

Abstract:

In the contemporary business world, manufacturing concern companies are becoming moreefficient in production process. Outsourcing is a process in which companies or producers getthe service or produced product or portion of the finished product from other company.Logistics is a functional system which is important for the improvment of efficiency, both inthe flow of goods and information and to meet low-cost, reliable delivery, and fast objectiveswithin a company and throughout a network of companies. The outsourcing of logisticsactivities to Logistics Services Providers or Third Party Logistics (3PL) companies hasbecome a common practice in current business world. Logistics outsourcing is the use ofexternal companies to perform logistics functions that have traditionally been performedwithin an organisation and the functions performed by the third party can encompass theentire logistics process or selected activities within that process. This thesis or research hasbeen conducted on a manufacturing sector‟s company which is located and working inPakistan. This company is working with the name of Pakson International. Company has outsourced three logistics activities which are freight forwarding, transportation andwarehouse management. In this thesis, there is focus on the comparison of the logisticsoutsourcing process inside the Pakson International and in literature.

Mahanga, Mwaka. "Unknown Exception Handling Tool Using Humans as Agents." UNF Digital Commons, 2015. http://digitalcommons.unf.edu/etd/563.

Full text

Abstract:

In a typical workflow process, exceptions are the norm. Exceptions are defined as deviations from the normal sequence of activities and events. Exceptions can be divided into two broad categories: known exceptions (i.e., expected and predefined deviations) and unknown exceptions (i.e., unexpected and undefined deviations). Business Process Execution Language (BPEL) has become the de facto standard for executing business workflows with the use of web services. BPEL includes exception handling methods that are sufficient for known exception scenarios. Depending on the exception and the specifics of the exception handling tools, processes may either halt or move to completion. Instances of processes that are halted or left incomplete due to unhandled exceptions affect the performance of the workflow process, as they increase resource utilization and process completion time. However, designing efficient process handlers to avoid the issue of unhandled exceptions is not a simple task. This thesis provides a tool that handles unknown exceptions using provisions for exception handling with the involvement of human activities by using the BPEL4PEOPLE specification. BPEL4PEOPLE, an extension of BPEL, offers the ability to specify human activities within BPEL processes. The approach considered in this thesis involves humans in exception handling tools by providing an alternate sub process within a given business process. A prototype application has been developed implementing the tool that handles unknown exceptions. The prototype application monitors the progress of an automated workflow process and permits human involvement to reroute the course of a workflow process when an unknown exception occurs. The utility of the prototype and the tool using the Scenario Walkthrough and Inspection Methods (SWIMs) are demonstrated. We demonstrate the utility of the tool through loan application process scenarios, and offer a walkthrough of the system by using examples of instances with examples of known and unknown exceptions, as well as a claims analysis of process instances results.

Abstract:

Flash is the unwanted or excessrubber material that presents on the outersurface of themolded rubber product. This will affect the surface finish; it is a cosmetic defect andit can be removed. It forms because of the leak or the excess molded rubber materialbetween the surface of the mold, typically on the parting line, (Jordan Anderson,2014). The presence of flash will reduce customer satisfaction. There are manymethods to remove the flash. The method is selected according to the degree of flashextension and the location where it occurs.The project aims to design a semi/full automated machine, which helps for having asmooth and fine surface finish of the weight plates. These plates are made up of rubberfor the ELEIKO group. The weight plates have different weights from 10 to 20 kg,but the diameter of each plate stays the same, but the thickness will be different foreach plate. The machine should be designed that removes all the excess rubber andshould smoothen the outer surface of the weight. The purpose of this work is to gainknowledge about different product development methods, respective tools, andtechniques that are used. The machine should be user- friendly, should not becomplicated, should not damage the workpiece (marks or trace of the blade), shouldnot put the employer in danger, and economically feasible.This report presents the progress of designing of the product, product development,methods, and literature study. The designed model can construct in the industry fortheir problem they are faced by the flash. The model is very simple and unique so thateveryone can perform the task without any previous experience. Material alternativeswere evaluated as well as manufacturing possibilities. The designed machine was theoffered for free as means for further research and development.

Abstract:

The Master of Engineering Management Project was sponsored by the Canterbury Earthquake Recovery Authority (CERA) and consisted of two phases: The first was an analysis of existing information detailing the effects of hazardous natural events on Canterbury Lifeline Utilities in the past 15 years. The aim of this “Lessons Learned” project was to produce an analysis report that identified key themes from the research, gaps in the existing data and to provide recommendations from these “Lessons Learned.” The Second phase was the development of a practical “Disaster Mitigation Guideline” that outlined lessons in the field of Emergency Sanitation. This research would build upon the first stage and would draw from international reference to develop a guideline that has practical implementation possibilities throughout the world.

Injektionsattack är den mest kritiska säkerhetsapplikationen för webbapplikationer, och SQL-injektion (SQLi) -attack är den mest rapporterade injektionsattacken på webbapplikationer. I denna avhandling har vi identifierat angreppsteknikerna som används av angripare och vi ger också riktlinjer så att programmerarna kan skriva webbapplikationskoder på ett säkert sätt för att förhindra SQLi-attackerna.Metoden som tillämpas för forskningen är litteraturstudie och vi använde vägen bevis genom demonstration för att få den tydliga bilden. Det första steget var att ta reda på kodningsfelen, då utformade vi riktlinjer som kan hjälpa till att skydda webbapplikationer från SQLi-attacker. Denna avhandling kommer att hjälpa programmerarna att förstå de olika kodningsbristerna och hur dessa kodningsfel kan förhindras och för detta har vi använt bevis genom demonstration. Denna avhandling kommer också att bidra till den allmänna medvetenheten om SQLi-attacker, attacker och riktlinjer för programmerare som designar, utvecklar och testar webbapplikationer.
Injection attack is the most critical web application security risk, and SQL-injection (SQLi) attack is the most reported injection attack on web applications. In this thesis, we have identified the attacking techniques used by attackers and we are also providing guidelines so that the programmers can write web application code in a secure way, to prevent the SQLi attacks.The methodology applied for the research is literature study and we used the way proof by demonstration to get the clear picture. The first step was to find out the coding flaws, then we designed guidelines that can help to protect web applications from SQLi attacks. This thesis will help the programmers to understand the various coding flaws and how those coding flaws can be prevented and for this, we have used proof by demonstration. This thesis will also contribute to the general awareness of SQLi attacks, attack types and guidelines for the programmers who are designing, developing and testing web applications.

Abstract:

IoT devices provide immense contributions in fields of education, communication, business, science, industrial zones, permeating various aspects of everyday life. Despite these benefits, their diversity, heterogeneity, and rapid development can introduce significant challenges, especially when the secure design has not been incorporated into their software lifecycle. Consequently, they can be targeted by malicious attackers, resulting in important security threats that need to be addressed. The main goal of this research is to explore the benefits of securing IoT devices after deployment, by examining, analyzing, and comparing default vs secure IoT device configurations. This will allow us to make assumptions regarding the differences in behavior, patterns, and motives of the attackers, as well as to measure the performance output between the two environments. To achieve our goal, we make extensive use of honeypot systems simulating the two different environments and collect log data to conclude meaningful information. As a secondary goal, we also explore any potential performance degradation for default vs secure configurations. The produced results suggest that there is a major difference both in terms of how the attackers approach a hardened IoT device/service, and how a device is affected in terms of operability and performance.

Abstract:

A steel slitting process is simulated using FEM (Finite Element Method) in order to see potential defects along the edge in a steel sheet after it has been cut. The model's results were compared to microscope images of the steel sheet in order to verify accuracy. The purpose is conceptual and to find a model that successfully simulates a steel cutting process and (hopefully) how the edge depends on different parameters. The model developed seems to achieve this task, and a more thorough calibration of the model could result in (more) optimal parameters for the machine to use.

Abstract:

ASSA AB develops different types of products that can be used in or around doors. ASSA offers a complete door solution to the customers. Many of these products are linked together and work for a complete formation of access control. ASSA has recently developed a new communications bus for some of their products. One advantage of the new communication bus is that each product should be able to offer different kinds of added values to the customers.

This master thesis main focus is to find a model to describe the predicted life length of ASSA:s motor lock called 811C50, which includes a study that determine which environmental parameters that can affects the motor locks life length. This master thesis is also a pre-study for further work of an existing motor lock.

The chosen test model, full parameter test, leads to a life length equation. This equation shall later on be implemented in the motor locks so the motor locks itself can predict its own life length. To make the equation completed different parameters, that can affect the motor locks life length, are needed. This can be implemented through different technological tests and to succeed with the test, right test equipment is needed. No establish test equipment was available, which required that new test equipment, which could test all motor locks, were build. On the bases from interviews with engineers at ASSA it was established that the following parameters probably can affect the motor locks life length: temperature, air humidity, dust, corrosion, side load and vibration. Not until certain factors and coefficients have been determined, for the equation, can the equation be used.

ASSA AB är ett företag som utvecklar olika typer av produkter som kan användas i eller runt en dörr. ASSA erbjuder en komplett dörrlösning till kunderna. Många av de här produkterna är sammankopplade och arbetar tillsammans för att komplett passersystem. ASSA har nyligen utvecklat en ny kommunikationsbuss för några av deras produkter. En fördel med den nya kommunikationsbussen är att varje produkt kan ge ett ökat mervärde för slutkunden.

Denna avhandling har som huvudsyfte att hitta en modell som kan beskriva livslängden för ASSA:s motorlås, 811C50. Till detta görs en studie för att undersöka vilka miljö parametrar som kan påverka motorlåsets livslängd. Denna avhandling kan även ses som en förstudie där målet är att vidareutveckla det befintliga motorlåset.

Den valda modellen, full variabel test, leder till en livslängdsekvation. Denna ekvation kommer sedan att bli implementerad i motorlåset så att låset själv kan prediktera sin egen livslängd. För att göra ekvationen komplett behövs olika parameterr som kan påverka motorlåsets livslängd identifieras. Detta kan ske genom olika tekniska test och för att lyckas med testen krävs rätt testutrustning. Ingen befintlig testutrustning fanns tillgänglig vilket resulterade i en ny testutrustning som kunde testa alla motorlås utvecklades. Utifrån intervjuer med ingenjörer på ASSA kunde det fastställas att följande parameterr troligtvis kan påverka motorlåsets livslängd: temperatur, luftfuktighet, damm, korrosion, listtryck och vibrationer. Inte förens koefficienter, till ekvationen, har blivit fastställda är ekvationen färdig att användas.

Full text

Abstract:

In this master thesis, performed at Sandvik Coromant Västberga (Stockholm), a comprehensive study has been made to investigate the wear on textured alumina (Inveio™) coated cutting tools when turning low-alloy steels. Specifically, wear studies have been made on tools’ rake faces when turning two separate batches of SS2541, after an initial turning time of 4 min. A particular focus has been given to elucidate what particular role the inclusions might have for the wear of the alumina coating onthe tools. Evaluation of tool wear has been made by employing several different analytical techniques, such as LOM, SEM, Wyko, Auger-spectrometry (AES), EPMA and XRD. The results shows that the arisen wear marks on both tested tool types may be divided into three separate and highly distinguishable wear zones, denoted here in thiswork as “wear bands”. Largest amount of wear tended to occur initially at the topmost part of the 3rd wear band. This was true for both tested tool types. This area demonstrated a characteristic 'lamellar' wear pattern, composed of narrow andstructured ridges. All the tools tested demonstrated the adhesion of workpiece materials of various composition that formed into smeared layers in these formed ridges. Depth-profiling Auger-spectrometry revealed that a significant amount of calcium was present in the machined alumina coating layers. This suggests that a reaction between the calcium-containing inclusions found in the steel and the aluminacoating layer had occurred during the performed turning tests.These results arecontradictory to the general belief that alumina is chemical inert during machiningand has previously, to the authors knowledge, not yet been published. Based on the results from this thesis and from a literature review concerning thebehavior of α-alumina during deformation, a new theoretical wear model has been developed. In this model, it is emphasised that the sliding of hard inclusions from the steel may activate pyramidal slip systems in the textured alumina coating. This causes a nano-crystallisation and/or amorphisation in the topmost part of the coating, which facilitates the further wear of these coated tools.
I detta examensarbete, som har utförts vid Sandvik Coromant i Västberga (Stockholm), har en omfattande studie gjorts i syfte att undersöka slitaget på texturerad aluminiumoxid-belagda skärverktyg (Inveio™) vid svarvningen av låglegerade stålsorter. Förslitningsstudier har framförallt gjorts på verktygens spånsidor vid svarvningen av två separata batcher av stålsorten SS2541 efter en inledande ingreppstid på 4 min. Ett särskilt fokus har även ägnats åt att belysa vilken roll stålets inneslutningar kan ha för slitaget av aluminiumoxidbeläggningen. Utvärderingen av verktygsslitaget har gjorts med hjälp av flera olika analytiska tekniker, däribland LOM, SEM, Wyko, Auger-spektrometri (AES), EPMA samt XRD. Resultaten från detta examensarbete visar på att det uppkomna slitaget på de verktyg som har testats kan uppdelas till tre separata och mycket distinkta ”slitagezoner”. Dessa zoner har för detta arbete benämnts som ”nötningsband”. Störst förslitning framträdde initialt i den översta delen av det 3:e nötningsbandet på de testade skärverktygen. Detta område uppvisade ett karaktäristiskt ”lamell”-liknande utseende, bestående av smala och strukturerade åsar och skåror. Vidare uppvisade samtliga undersökta verktyg på förekomsten av påsmetat arbetsmaterial av varierande sammansättning i dessa bildade åsar. När de slitna verktygen undersöktes med djuprofilerande Auger-spektrometri påvisades det att en signifikant mängd kalcium fanns inuti aluminiumoxidbeläggningen. Detta tyder på att en reaktion mellan de kalciuminnehållande inneslutningarna (som finns inuti stålet) och aluminiumoxidbeläggningen har reagerat med varandra under bearbetningsförloppet. Dessa resultat är motsägande till den allmänna uppfattningen om att aluminiumoxid är kemiskt inert vid bearbetningen av stål. Därutöver har dessa resultat även, till författarens kännedom, aldrig tidigare publicerats. Baserat på de resultat som har erhållits från detta examensarbete, och från en omfattande litteraturstudie gällande deformationen av α-aluminiumoxid, har en ny teoretisk förslitningsmodell utarbetats. I denna modell betonas det särskilt att glidningen av hårda inneslutningar från stålet kan aktivera s.k. pyramidala glidsystem i den texturerade aluminiumoxidbeläggningen. Detta orsaker en nano-kristallisering och/eller amorfisering av den översta delen av aluminiumoxidbeläggningen. Denna omvandling tros kunna underlätta den fortsatta förslitningen av dessa belagda skärverktyg.

Abstract:

Risk can be viewed as a state where there is a possibility of a loss but also a hope of gain. To realise the existence of a risk, one must be aware of both the gains and losses incurred.Increased number of natural disasters and companies having global supply chains to a higher extent, are both factors which have increased the number of risks that can affect anorganisation’s supply chain negatively. This fact has made it even more important to focus on risk prevention. In the beverage industry market, characterized by fast-moving products,manufacturing companies like Coca-Cola Enterprises Sweden (CCES) can be highly affected if disturbances occur in their supply chain. Risk management is, according to ISO 31000, “coordinated activities to direct and control an organization with regard to risk “. A risk management processes therefore aims at mitigatingnegative impact of external and internal disturbances in order to avoid interruptions in production, product quality issues and financial losses. CCES’s control over internal processes and its disturbances is mostly based on reactive approaches rather than a proactive strategy and there exist no guidelines of how to identify and handle occurring disturbances. The main purpose of the project has therefore been to identify the most critical risks the company is facing within their “Source” and “Make” processes, and find both proactive and reactive mitigation actions. Another significant part of the project delivery is to present a model for how the company should organize and maintain a sustainable risk picture. The model aims to present a dynamic risk management process that can be used by CCES as well as other companies in the future. The project consists of three major phases; Risk Identification, Risk Avoidance Mapping and Implementation of a Risk Management Process. In the first phase, the brainstorming tool Hazard and Operability (HAZOP) has been used during workshop events for risk identification and assessment. Some of the most critical risks identified are; Sabotage during transport from supplier to CCES, Lack of spare parts for maintenance, Lost production time due to long beverage change overs and Filling bottles with too much beverage. In order to find feasible preventive and reactive mitigation actions for the critical risks, both employee interviews and the Supply Chain Operations Reference (SCOR) model has been applied. Some of the actions recommended to perform are concluded to be; Let suppliers own transports, Standardize the product change process and the shift hand overs and Implement routines of having locked transports from supplier to CCES. The structure of the project has acted as a basis for the recommended way of continuing the risk management work at CCES. The authors have identified the importance of keeping the risk management process dynamic, and therefore a Risk Register have been introduced for documentation and follow-up. Another way of following up the risk management work, is to perform Risk Audits after the event of a disturbance. This will help the organisation to realize the impact a certain disturbance brings, but it will also measure of the recovery work’s effectiveness. The authors highlight the importance of having a dedicated owner of the risk management process in order to keep it dynamic. A complete risk management process has finally been created, adaptable to different kind of organisations. By making this process a part of SCOR, the authors believes that the process can be used to identify individual risks within the management processes Plan, Source, Make, Deliver and Return for all SCOR member companies. Thereafter, a general risk mapping can be created from the individual risks that can be used to share information and experiences among the member companies.
En risk kan förklaras som ett tillstånd där det finns en chans att vinna, men också en sannolikhet för förlust. För att vara medveten om en risks existens måste man därför förstå både vad det finns att förlora och vinna. Under de senaste årtiondena har antalet naturkatastrofer och annan extern påverkan ökat. Detta i kombination med att företag idag har globala värdekedjor i allt större utsträckning, har gjort att organisationer utsätter sig för risker till en större grad idag. Därför har betydelsen av att fokusera på riskförmildrande åtgärder ökat. I dryckesindustrin, karaktäriserat av snabbrörliga produkter, kan företag såsom Coca-Cola Enterprises Sweden (CCES) påverkas hårt om störningar sker i deras värdekedja. Risk Management är, enligt ISO 31000, ”koordinerade aktiviteter för att styra och kontrollera riskhantering i en organisation”. En riskhanteringsprocess ämnar därför förmildra negativ påverkan av interna och externa störningar för att undvika till exempel avvikelser i produktion, försämrad produktkvalitet och finansiella förluster. CCES’s kontroll över interna processer och dess störningar baseras främst på reaktiva åtgärder, och företaget har inga riktlinjer för hur de ska identifiera och hantera uppkommande störningar. Syftet med detta projekt har därför varit att identifiera kritiska risker inom företagets leverantörs- och produktionsprocesser och att hitta proaktiva och reaktiva lösningar för att förmildra och undvika störningar. Ytterligare en stor del av projektets syfte har varit att presentera en dynamisk process för hur CCES, samt andra företag, ska organisera en hållbar riskbild. Projektet består av tre huvudsakliga delar; riskidentifiering, riskförmildrande åtgärder och implementering av en riskhanteringsprocess. I den första fasen har verktyget Hazard and Operability (HAZOP) används under workshops för att identifiera och värdera risker. Några av de mest kritiska riskerna som identifierats är; Sabotage under transport från leverantör till CCES, Brist på reservdelar för underhållsarbete, Förlorad produktionstid på grund av för långa dryckesbytartider och Fyller flaskor med för mycket dryck. För att hitta passande reaktiva och proaktiva lösningar för de kritiska riskerna har både intervjuer med anställda genomförts och referensmodellen Supply Chain Reference Model (SCOR) använts. Några av de åtgärder rekommenderade att göra har identifierats till att vara; Låta leverantörerna själva sköta transporter, Standardisera produktbytesprocessen samt skiftöverlämningar och Implementera rutiner för att ha låsta transporter från leverantör till CCES. Strukturen av projektet har använts som en bas för den rekommenderade strukturen på CCE’s fortskridande arbete inom riskhantering. Författarna vill bestryka vikten av att hålla den framtida riskhanteringsprocessen dynamisk och i detta syfte har därför ett riskregister tagits fram för dokumentation och uppföljning. Ett annat sätt att följa upp riskprocessarbetet är att genomföra så kallade audits efter en störning har inträffat. Detta hjälper organisationen både att förstår en störnings påverkan på verksamheten, men fungerar också som ett verktyg för att mäta hur effektivt återhämtningsarbetet efter en störning har varit. Författarna menar också att en dedikerad ägare till riskprocessen är av stor betydelse för ett dynamiskt, framgångsrikt och effektivt riskarbete. En fullständig riskhanteringsprocess har slutligen sammanställts, användbar för många olika typer av organisationer. Genom att göra processen till en del av SCOR-modellen, kan processen i framtiden användas till att identifiera individuella risker inom de fem managementprocesserna Planering, Inköp, Tillverkning, Leverans och Retur för alla SCOR’s medlemsföretag. Därefter menar författarna att en generell kartläggning över de mest kritiska riskerna inom varje managementprocess kan skapas för att dela information och utbyta erfarenheter mellan medlemsföretagen.

Abstract:

With the transition to Industry 4.0, actors in many industries face challenges such as how to successfully implement technical solutions and retain competitiv eadvantages. In the smart waste management sector, many solutions have been presented in how to create effecient sensors but a practical way of comparing these solutions is non-existent. From research within Industrial Internet of Things (IIoT) and interviews with operators at Scania, we present a clear and effective way of comparing smart waste management sensors with regards to operational effectiveness. Along with this, we present a way to measure fill volume of garbage containers using monocular depth estimation and compare this to using ultrasonic sensors. Our findings show that depth estimation with deep convolutional neural networks is viable as long as environmental conditions can be controlled, although, we have also found that ultrasonic sensors outperform depth estimation in many metrics and is the desired way of measuring fill level of containers in many applications. Despite this, the results of this research show promise in that depth estimation can be used in conjunction with object recognition models, leading to the obsolescence of ultrasonic sensors in more complex applications.
Med den tekniska omvandlingen till Industri 4.0, ledande aktörer i många branscher ställs inför utmaningar såsom hur de ska implementera tekniska lösningar och bibehålla konkurrenskraft. Inom området för smart avfallshantering har många tekniska lösningar presenterats som på ett effektivt sätt mäter soptunnenivåer men ett praktiskt sätt att jämföra dessa lösningar saknas. Från forskning inom Industrial Internet of Things (IIoT) och intervjuer med operatörer på Scania har vi tagit fram ett koncist och konkret sätt att jämföra dessa lösningar med avseende på operativ effektivitet. Tillsammans med detta har vi också tagit fram en djupestimeringsmodell som med hjälp av djupa konvolutionsneuronsnätverk kan mäta fyllnadsvolymen av soptunnor. Vi har visat i vår forskning att detta djupestimeringsnätverk är ett möjligt alternativ till andra sensorer. Vi jämför sedan detta system mot ultraljudssensorer och har funnit att ultraljudssensorerna presterar bättreän djupestimeringsmodellen på flera av de centrala mätvärdena. Trots detta så drog vi slutsatsen att vår metod att mäta fyllnadsvolym av soptunnor med hjälp av djupestimering kan användas tillsammans med objektigenkänning i mer komplexa applikationer för att undvika användandet av enklare sensorer, så som ultraljud.

Abstract:

Lithium-ion batteries are a rapidly growing power source for mobile applications such as electric vehicles. A battery model algorithm that estimates and predicts important battery parameters like terminal voltage and state-of-charge is necessary to maintain safe operation during discharge. Hence, a semi-empirical electrochemical-based model was proposed and implemented in MATLAB for discharge simulation and parameter estimation. This thesis also investigated several essential factors like internal resistance and operational temperature, which impact a battery cell during discharge. The proposed model was a modification of Shepherd’s model that included both kinetic and diffusive components representing the total battery overpotential and a temperature- dependent coefficient. These were used for the determination of the battery’s internal resistance and the temperature effect. The model accounts for all dynamic characteristics of a Li-ion battery, including non-linear open-circuit voltage, internal resistance, discharge current, and capacity. Model validation was performed using test profiles, including data provided by the battery manufacturer and experimental data for a test profile provided by Saab Dynamics. The simulated profiles were found to match the measured profiles. Although, some deviations occurred, especially during rapid changes in C-rates. The proposed model in this work shows that the simulation results compared to the experimental data had deviations within ~2% for the constant current discharge test, and the dynamic model managed to cover the experimental discharge voltage during different temperatures with good consistency and minor errors. Therefore, the proposed model can compete with other battery modeling methods.

Abstract:

This thesis is the final assignment for the program master of science in Industrial Design Engineering at luleå university of technology. The timespan is September of 2017 and early January 2018 and is equivalent to 30 high school credits. The work was performed at Martinsons Såg in Bygdsiljum, Sweden.Martinsons is Sweden’s largest producer of cross-laminated timber, crosslam. The staff is divided into two shifts with nine workers each. The production consists of three sections, gluing, CNC and shipping. The factory was expanded in early 2017 but did not achieve planned output. The last section, the shipping, is a bottleneck. The object of this thesis is to find a layout that solves the bottleneck and improve the working conditions in the shipping, and the pace of the system should be determined by the first process, the pressing. The production starts with the planks. Planks are cut to the right dimensions by a saw and placed in layers. Glue is then applied, and more layers are placed and moved to a press while the glue dries. It results in panels. The maximum size of the panels is 16x3 m. A CNC saw cuts the panels to litteras, custom order parts used to build everything from houses to public areas. The workers pack the littera manually. When the litteras are packed, the packages are loaded on trucks for delivery to the customers. The theoretical background of this thesis consists of three major subjects: industrial design engineering, ergonomic and lean production, with a focus on waste reduction. To understand the system the flows and working procedures were documented with observations, interviews, a survey and some filming. An OWAS were used to observed the ergonomic risks and analyse how they can be avoided. Later in the project were a brainstorming session and workshop used to generate concepts to solve the problems. The concepts were evaluated with a value matrix. The results from the examination of the system showed that the real bottleneck in the system was the crane. It was slow and is also used in the waste flows. Two packaging stations for the litteras cannot be used because of the flow of the sawdust, lowering the capacity and flexibility in the packaging. Summarised, the crane could not deal with the demands from the rest of the system. The ergonomic problems consisted of bent and twisted backs while the workers pack the littera. This thesis proposes an investment plan to solve these problems. It consists of two investments that expand the building and expand conveyors, thus removing much of the lifting much lifting with the crane. The waste and littera flows are separated to allow the crane to focus on the main flow of littera.Two new kinds of packaging stations are implemented to help with the packaging: standard stations that pack the littera on lifts and wall packaging stations that packs littera meant for walls that have many weaknesses. The standard stations consist of scissor lift tables that help reduce the time spent with a bent back while packaging. The temperature is maintained at comfortable levels with an airlock to the outside.

Abstract:

This thesis deals with the development of a Conceptual Design Tool for unmanned helicopters, so called VTOL UAVs. The goal of the Design Tool is:

• Quick results

• Good accuracy

• Easy to use

The two first points of the goal are actually more or less dependent on each other. In almost all cases a high accuracy gives a slow calculator and vice versa. In order to fulfill the goal a compromise between calculation accuracy and calculation time needs to be done.

To make the Design Tool an easy to use program a graphical user interface is used. The graphical user interface allows the user to systematically work his way thru the program from a fictive mission to a complete design of a helicopter. The pre-requirements on the user have been eliminated to a minimum, but for the advanced user the possibilities to create more specific and complex helicopters are good.

In order to develop a Conceptual Design Tool the entire helicopter needs to be seen as a complete system. To see the helicopter as a system all of the sub parts of a helicopter need to be studied. The sub parts will be compared against each other and some will be higher prioritized than other.

The outline of this thesis is that it is possible to make a user friendly Conceptual Design Tool for VTOL UAVs. The design procedure in the Design Tool is relatively simple and the time from start to a complete concept is relatively short. It will also be shown that the calculation results have a good agreement with real world flight test data.

Abstract:

There is a lack of relevant research of fixed assets revaluation practices in New Zealand. This study provides some insights as (1) why some New Zealand firms choose to revalue their fixed assets; (2) when will a firm revalue its fixed assets; and (3) whether fixed asset revaluation provides information to investors. This research attempts to explain the motivations of the management’s fixed asset revaluation decision in New Zealand. The empirical analysis includes five common explanatory variables, such as gearing (debt-equity ratio), liquidity, market-to-book ratio, firm size, and fixed asset intensity. In addition, the relationship between asset revaluation and share price movements of the firms are examined to determine the perceived usefulness of fixed asset revaluation information for the capital market in New Zealand. The study results show that fixed asset intensity and firm size significantly contribute to the revaluation decision. In contrast to the findings of previous studies (Whittred and Chan, 1992; Brown, Izan, and Loh, 1992; and Missionier-Piera, 2007), the level of corporate gearing is negatively related to the probability of revaluing assets for the sample of New Zealand firms in this study. However, the effect of the level of gearing on the revaluation decision is insignificant. The empirical results did not show any significant outcomes and relationships for investigated year 1998. This is because 1998 signified the end of recession and the beginning of economic growth in New Zealand. At the end of a recession, the changes in the country’s economic environment might have superseded individual firms’ considerations in management decision making process. The empirical results show that the practice of revaluation increased sharply with the adoption of the IFRS in 2005 in New Zealand. About 28.1% of the revaluation announcements under study were made in 2005 compared to just over 15.8% in 2001. Furthermore, the empirical results show negative returns accrue to firms prior to the publication of financial statements that carry revaluation announcements. These negative returns are reverted as soon as the revaluation information is made public. These gains are again maintained for at least a month after the announcements are made. Comparing frequent revaluers to first time revaluers, the results show that asset revaluation information is relevant to investors. Frequent revaluers gained only 0.8% announcement abnormal returns while First time revaluers gained over 4% in the 2005.

Abstract:

Wireless Sensor Networks (WSNs) are based on innovative technologies that had revolutionized the methods in which we interact with the environment; i.e., through sensing the physical (e.g., fire motion, contact) and chemical (e.g., molecular concentration) properties of the natural surroundings. The hardware in which utilized by WSNs is rapidly evolving into sophisticated platforms that seamlessly integrate with different vendors and protocols (plug-n-play). In this thesis, we propose a WSN framework which provides assistance with monitoring environmental conditions; we focus on three main applications which include: a. Air-quality monitoring, b. Gas-leak detection, and c. Fire sensing. The framework involves four specifications: 1. Over the air programming (OTAP), 2. Network interconnections, 3. Sensors manageability, and 4. Alarm signaling. Their aim is to enhance the internetwork relations between the WSNs and the outside-world (i.e., main users, clients, or audience); by creating a medium in which devices efficiently communicate, independent of location or infrastructure (e.g., Internet), in order to exchange data among networked-objects and their users. Therefore, we propose a WSN-over-IP architecture which provides several renowned services of the Internet; the major functionalities include: live-data streaming (real-time), e-mailing, cloud storage (external servers), and network technologies (e.g., LAN or WLAN). WSNs themselves operate independently of the Internet; i.e., their operation involve unique protocols and specific hardware requirements which are incompatible with common network platforms (e.g., within home network infrastructure). Hybrid technologies are those which support multiple data-communication protocols within a single device; their main capabilities involve seamless integration and interoperability of different hardware vendors. We propose an overall architecture based on hybrid communication technology in which data is transmitted using three types of protocols: 802.11 (Wi-Fi), 802.15.4 and Digimesh (WSN).

Abstract:

Scoops are important parts in an aircraft engine design, as they provide airflowto different equipment and subsystems. The optimization of such a component isessential in order to find a design that can perform properly within a range of flightconditions, with a minimum impair of main flow aerodynamic performances. Scoopdesign methods are generally based on previous experimental results and are usuallyconstrained by the limited space available. The studied configuration concerns theflush scoop located inside the secondary flow of turbofans which provides flow fora turbine cooling equipment. Depending on flight conditions and engine workingpoint, this scoop will experience various flow regimes, from low mass flow rates tochoke flows. Therefore, the study of several scooped mass flow rates is mandatoryto extract the scoop behaviour. The thesis concerns the preliminary step beforea 3D CFD optimization : a study of influence is run on the baseline geometry inorder to investigate the robustness of the solution computed using different methodsand to determine the parameters to be optimized. Firstly, the full post-processingmethodology is defined to properly evaluate the performance of a design (scoopefficiency, induced pressure losses). A second step consists in analysing the abilityof CFD solvers to capture the different flow behaviour. This point is addressed bycomparing solvers (Fluent, elsA, PowerFLOW), meshes (structured, unstructured)and turbulence models. The third step deals with the optimization strategy definitionto improve the scoop design and thus the engine fuel consumption.
