Full textAbstract:
In recent years there has been an increased emphasis on source data capture, point-of-care systems or bedside computing in the health care industry. Many of those involved in health care have speculated that bedside computing could contribute to efficient, cost effective health care delivery.
The purpose of this quasi-experimental study was to evaluate the effect of a bedside automated online nurse documentation system using a methodology designed to overcome some of the difficulties of previous studies. The first of four objectives was to determine the effect of the automated system on nurse productivity. The second objective was to determine the effect of the system on some nursing behaviours that have been predictors of quality of care. The third objective of the study was to evaluate nurse satisfaction with on-line bedside computing. Evaluation of the acceptance of the bedside computer by the patients and their satisfaction with their care was the final objective.
The automated bedside-based nurse documentation system was implemented on a twenty-two bed Plastic Surgery unit in a quaternary care teaching hospital. The automated nurse documentation system was developed by the hospital over a three year period (1986-1989). Four bedside computers were placed in a four bed experimental room; a second four bed room was used as the control room. Two terminals with access to the bedside-based system were located at the nursing station. Sixteen full time registered nurses participated in the study. The nurses used the automated bedside system when documenting care for patients in the experimental room and the manual, nursing station based, paper system to document care for patients in the control room. Questionnaires and observations were used to collect data over the four months of the study (June through September, 1990). The results showed no increase in nurse productivity. The quality of care results showed more immediate documentation of the nurses' observations and interventions and more time spent viewing patient data in the experimental state. There was no significant difference between the control and experimental state in the nurses' reported ability to provide individualized care. The nurses expressed a general level of dissatisfaction with the on-line bedside-based system and a general dissatisfaction with documenting at the patient bedside. The nurses found the manual system to be significantly more convenient than the automated system. In addition, the nurses found the presentation of patient data to be significantly better in the manual system. There was no significant difference between the reported satisfaction of patients with their care and their feelings and attitudes about the use of computers by nurses and in health care in the control and experimental rooms.
The results of the study lead the investigator to explore implications for implementation of bedside computing for nurses.<br>Medicine, Faculty of<br>Population and Public Health (SPPH), School of<br>Graduate

Peets, Sven. "Specification, design and evaluation of an automated agrochemical traceability system." Thesis, Cranfield University, 2009. http://dspace.lib.cranfield.ac.uk/handle/1826/4495.
Full textAbstract:
Traceability through all the stakeholders in food production is an issue of increasing importance, being specifically required by the regulations for food safety and quality (EC 178/2002), and for compliance with environmental protection. The agricultural market perceives a need for systems and technologies to automate the currently manual process of producing records of agrochemical inputs loaded into a spraying machine. A novel prototype Automated Agrochemical Traceability System (AACTS) to identify and weigh agrochemicals as they are loaded into crop sprayer has been designed, constructed, fitted to a machine and evaluated with commercial operators. The functional blocks of the system are a 13.56 MHz RFID reader, 1.4 litre self cleaning weighing funnel mounted on a 3 kg load cell, a user interface with a screen and three user command buttons (Yes, No, Back), and a progress bar made of 8 coloured LED’s (green, amber, red). The system is able to trace individual agrochemical containers, associate the product identity with national agrochemical databases, quantify the required amount of product, assist the sprayer operator and control workflow, generate records of sprayer inputs and interoperate with (recommending extensions to) task management standards as set out in ISO 11783-10. The evaluation of the quantity weighing has demonstrated that with such a system, the principal noise component is in the range of 33–83 Hz, induced by the operating tractor engine. A combined 3 Hz low pass digital filter with a second stage rolling mean of 5 values improves performance to allow a practical resolution of 1 gram (engine switched off) to 3.6 grams (sprayer fully operational) with a response appropriate to suit human reaction time. This is a significant improvement over the ±10 grams of the work of Watts (2004). An experiment with 10 sprayer operators has proved that in the majority of cases (92%) an accuracy equal or better than ±5% is achieved regardless of dispensing speed. The dispensed amounts (100.36% of target) and recorded (100.16%) are in accordance with prescribed values (100%; LSD(5%) 2.166%), where amounts dispensed by manual methods (92.61%) differ significantly from prescribed and recorded value (100%). The AACTS delivers a statistically similar work rate (211.8 s/task) as manual method (201.3 s/task; Δt = 10.5 s/task; LSD(5%) 28.2 s/task) in combined loading and recording cycle. Considering only the loading time (181.2 s/task) of manual method, the difference is 30.6 s/task (LSD(5%) 30.1 s/task). In practice this difference is believed to be marginal compared to the time required to load the water, random external events during the spraying session and in time moving, checking and storing paper records. The integrated weighing funnel concept is another significant improvement over previous work. Using this system, the mean duration of measuring per container for all tasks (34.0 s) is approximately half the time (68.5 s) achieved by Watts (2004). The AACTS was rated to be safer than the manual method regarding operator health and safety and risk of spillage. All operators who evaluated the AACTS were interested in purchasing such a system. The work confirmed that an RFID system was an appropriate media for agrochemical identification performing more than 250 product identification operations during operator tests without failure, with a speed of operation <1 s per cycle and reading distance of 100 mm. A specific format for RFID tag data is proposed for adoption, using low cost tags, that combines item level traceability with identification of products independently without access to worldwide databases. The AACTS follows ISO 11783 task management logic where a job is defined in a prepared electronic task file. It is proposed to extend the ISO 11783-10 task file to integrate the records provided by AACTS by handling the tank loads as individual products resulting from loading task and allocating them to spraying tasks. It is recommended to produce a production prototype following the design methodology, analysis techniques and performance drivers presented in this work and develop the features of user interface and records of tank content into software for ISO 11783-10 cabin task controller to deliver business benefits to the farming industry. The results with RFID encourage the adoption of RFID labelling of agrochemical containers. The reader may wish to read this thesis in parallel with Gasparin (2009) who has considered the business and industry adoption aspects of the AACTS.

Full textAbstract:
In spite of hard real-time embedded systems often being seemingly simple, modern embedded system designs often incorporate features such as multiple processors and complex inter-processor communication. In situations where safety is critical, such as in for instance many automotive applications, great demand is put on developers to prove correctness. The ForSyDe research project aims to remedy this problem by providing a design philosophy based on the theory of models of computation which aims to formally ensure predictability and correctness by design. A system designed with the ForSyDe design methodology consists of a well defined system model which can be refined by design transformations until it is mappable onto an application specific predictable hardware template. This thesis evaluates one such hardware template called the predictable System-on-a-Programmable-Chip. This hardware template was developed during the work on a masters thesis by Marcus Mikulcak [7] in 2013. The evaluation was done by creating many simple dual processor systems using the automated design flow provided by PSOPC. Using these systems, the time to communicate data between the processors was measured and compared against the claims made in [7]. The results presented in this thesis suggests that the current implementation of the PSOPC platform is not yet mature enough for production use. Data collected from many different configurations show that many of the generated systems exhibit unacceptable anomalies. Some systems would not start at all, and some systems could not communicate the data properly. Although this thesis does not propose solutions to the problems found herein, it serves to show that further work on the PSOPC platform is necessary before it can be incorporated into the larger context of the ForSyDe platform. However, it is the author’s genuine hope that the reader will gain appreciation for PSOPC as an idea, and that this work can instil interest into further working on perfecting it, so that it can serve as a part of ForSyDe in the future.<br>Även om hårda realtidssystem ofta verkar enkla så finner man i moderna inbyggda system numera ofta avancerade koncept såsom multipla processorer med komplicerad processor-till-processor-kommunikation. I situationer där säkerhet är ett kritiskt krav, som t.ex. i många applikationer inom bilindustrin, så föreligger enorma krav på de som utvecklar dessa system att kunna bevisa att systemen fungerar i enlighet med specifikationerna. Forskningsprojektet ForSyDe försöker lösa dessa problem genom att tillhandahålla en designfilosofi baserad på teorin om så kallade models of computation som via formella bevis kan garantera förutsägbarhet och korrekthet. Ett system designat med ForSyDes designmetodologi består av en väldefinierad modell av systemet som transformeras, tills dess den kan mappas mot en applikationsspecifik förutsägbar hårdvarumall. Detta examensarbete ämnar att utvärdera en sådan hårdvarumall som kallas predictable System-on-a-Programmable-Chip, eller PSOPC. Denna hårdvarumall utvecklades under arbetet med en masteruppsats av Markus Mikulcak [7] under året 2013. Utvärderingen bestod av skapandet av ett enkla tvåprocessorsystem med hjälp av PSOPCs automatiska designflöde. På dessa mättes sedan tiden för att kommunicera data mellan processorerna. Dessa kommunikationstider jämfördes sedan med de påståenden som görs i [7]. Resultaten som presenteras i detta examensarbete föreslår att nuvarande implementation av PSOPC-plattformen inte ännu uppnått tillräcklig mognad för att kunna användas i verkliga tillämpningar. De data som insamlats från många olika systemkonfigurationer visar att många av de genererade systemen uppvisar oacceptabla avvikelser. Några system startade inte ens och några klarade inte av att kommunicera data på ett korrekt sätt. Även om detta arbete inte föreslår några lösningar på de problem som presenteras häri så visar det på behovet av mer arbete med PSOPC-plattformen innan den kan bli en del av hela ForSyDe. Men, det är författarens genuina förhoppning att läsaren förstår de positiva aspekterna av PSOPC som idé, och att detta arbetet kan ingjuta intresse för att arbeta vidare med plattformen, så att den i framtiden kan bli en integral del i ForSyDe.

Full textAbstract:
Recirculating aquaculture systems (RAS) produce aquaculture products on land with minimal discharge of waste products and minimal water loss. High costs associated with waste treatment for RAS have triggered the growth of integrated aquaculture systems (IAS) which incorporate macrophytes (aquatic plants) into the treatment train. The objective of this research was to examine a pilot scale inland marine IAS with three different methods for solids treatment: a sand filter followed by a plant bed, only a plant bed, and geotextile bags. Florida Pompano (Trachinotus carolinus) were grown along with Smooth Cordgrass (Spartina alterniflora), Black Needle Rush (Juncus romerianus), and Red Mangrove (Rhizophora mangle). Between May 2011 and April 2012, water quality was tested at seven points located throughout the IAS for total suspended solids (TSS), chemical oxygen demand (COD), total nitrogen (TN), ammonium (NH4+), nitrate (NO3-), total phosphorus (TP), and orthophosphate (PO43-) concentrations every 4 to 6 weeks. Plant and soil samples were collected three times and analyzed for total nitrogen and total phosphorus. A statistically significant difference in the effluent concentrations for the three treatments was not found; however, due to the recombination of effluent from the solid treatments and the variability inherent in a pilot scale system it was difficult to isolate the individual efficiencies of each treatment. Therefore, on average the complete system achieved COD and TSS removal efficiency of 59% and 88%, respectively and TN and TP removal efficiency of 48% and 19%, respectively. Nutrient uptake by plants did not vary significantly between the plant beds. In general, the system provided sufficient nutrient removal for safe fish production, and the fish provided enough nutrients for ample plant growth.

Full textAbstract:
The distributed processing capabilities of local area networks has led to the development of "client-server" applications for microcomputers. Two separate computer programs, the client and the server, comprise the client-server system. The server program receives and services requests sent to it by the client program. More than one copy of the client program may be connected at a time to the server via the network with each instance of the client program operating on a separate computer. Two difficulties are encountered when testing such a system. First, since each client station is operated by one or more human-users, extensive evaluation is costly when several clients are operated for a substantial amount of time. A second problem is an inherent inaccessibility to information about internal system states. This thesis presents a method for automating performance evaluations of the server component of the client-server software system. Two changes to the original system are required. First, the human-user inputs to the system are generated using probability distributions. Second, an additional computer program, the test monitor, is added to the system in order to automate the accumulation and storage of test data.

Full textAbstract:
Anaesthesia Information Management System (AIMS) is an automated record keeping system that imports and stores patient’s vital signs information from a physiological monitor in real-time. However, only a handful of studies have examined the effect of automated record keeping system on anaesthetists’ cognitive performance. Therefore, the current thesis aims to evaluate AIMS in terms of anaesthetists’ attitude (Study 1) and its effect on their cognitive performance (Study 2). Study 1, a questionnaire study examined anaesthetists’ trust and acceptance of AIMS. Forty-two anaesthetists at Tuen Mun Hospital (TMH) and Po Oi hospitals (POH) have completed a self-reported questionnaire. Results found that anaesthetists generally adopted a positive attitude toward AIMS. They exhibited a high level of trust and acceptance of AIMS. Also, they perceived AIMS as highly useful and relevant to their job. Study 2, a simulation study compared AIMS with manual record keeping on anaesthetists’ vigilance, situation awareness (SA) and mental workload. 20 anaesthetists at TMH were randomly assigned to two conditions: (1) AIMS and (2) Manual. Each participant received a 45-minute scenario in a full-scale simulation. Participants were asked to take over a case of general anaesthesia and perform record keeping. Results showed that AIMS did not impair anaesthetists’ vigilance and SA. In addition, it reduced anaesthetists’ mental workload and enabled them to spend less time on record keeping task. The current thesis provides an evaluation of AIMS by using a human factors approach. It contributes to the understanding on the effect of AIMS on anaesthetist’ in terms of attitude and cognitive performance. Based on the evaluation, we generate some recommendation for designers and hospitals to address the limitation of AIMS in interface designs and to increase anaesthetists’ acceptance of AIMS.

Full textAbstract:
The research presented in this exegesis relates to the design, development and testing of a new Automated Essay Grading (AEG) system. AEG systems make use of Information Technology (IT) to grade essays. The major objective for AEG system developers is to build systems that grade as well as, or exceed the accuracy of, human graders.This research discusses the main theories that currently underpin existing systems. It then discusses a new theoretical concept, the Normalised Word Vector (NWV), which has been developed and tested during this research. This exegesis also synthesises into a cohesive discourse seven of the author’s papers on the NWV and related issues published during the period 2002 to 2007. The papers can be grouped into three themes as follows: the theory of NWV and related matters, the development of the system, and the testing of the system.Thirteen existing AEG systems have been identified in this research. Each system has its own set of unique features; some focus on grading for essay writing style, others for essay content, and others attempt to consider both aspects in assigning a score to an essay. The type and amount of feedback on an essay also varies amongst the systems; some provide feedback on essay mechanics and others provide feedback on missing content. The MarkIT system described in this exegesis primarily grades for essay content, with a secondary focus on style. It has the unique feature, which distinguishes it from the other systems, of providing interactive visual feedback on essay content. This enables the teacher and student to discuss how the essay can be improved to obtain a higher grade.In brief, the theory of the NWV is as follows. The words in an essay are ‘normalised’ to their root concepts in a thesaurus. The number of times these concepts occur in the essay (the counts) are then used to build the coordinates of the vector in the vector space induced by all the concepts in the thesaurus. This adaptation of the theory used for many years in the document retrieval industry enables very fast comparison of essay content, and enables MarkIT to grade in real time.In essence the system works by mathematically modelling, using multiple linear regression, the grading criteria used by human graders for a given essay. These criteria are extracted from a set of training essays, and include items such as the number of words, the number of nouns, the number of verbs, the number of adjectives, and the number of adverbs. The model is then used to grade the essays not previously graded by humans. It does this by measuring the predictor factors in the ungraded essays, and then applying the multiple regression equation. The cosine of the angle between the NWV for a student essay and the NWV for a model answer is often one of the significant predictor variables.The system has been tested with 390 Year 10 high school essays, of about 400 words in length, on the topic of ‘The School Leaving Age’. The correlation of grades amongst the human graders was 0.81, and the system scores matched this correlation of the human graders.

Full textAbstract:
In an increasingly globalized world with more and more distributed international supply chains, sustainability studies and policies need to consider socioeconomic and environmental interactions between distant places. Studies of the global biomass metabolism investigate physical flows between and within nature and human systems, thus providing a useful basis for understanding the interrelatedness of changes in one place with impacts elsewhere. Various methodological approaches exist for studying the human-nature metabolism and estimating the land embodied in international trade flows, a core element of assessing telecouplings in the global land system. The results of recent studies vary widely, lacking robustness and thus hampering their application in policy making. This article provides a structured overview and comparative evaluation of existing accounting methods and models for calculating land footprints. We identify differences in available accounting methods and indicate their shortcomings, which are mainly attributable to the product and supply chain coverage and detail, and biases introduced by the use of monetary flows as a proxy for actual physical flows. We suggest options for further development of global land footprint accounting methods, particularly highlighting the advantages of hybrid accounting approaches as a framework for robust and transparent assessments of the global displacement of land use.

The work presented in this dissertation examines the performance of two satellite radio communication systems by computer simulation. Two simulations were separately performed for a spread spectrum chirp system as an analog communications system, and for the Land Mobile Satellite System (LMSS) channel as a digital communications system.
For the simulation of analog communications, a spread spectrum system using chirp techniques called ‘Coded Multiple Chirp Spread Spectrum’ was proposed as a simple, cost-effective alternative for conventional spread spectrum systems. Its application as a spread spectrum overlay service on analog FM-TV was examined through the mutual interference analysis and spectral analysis using software programming.
For the simulation of digital communications, various digital modulation schemes as well as channel encoding, block interleaving/deinterleaving, and differential encoding techniques were used for a thorough performance evaluation of a Land Mobile Satellite System under fading conditions. For this purpose, an LMSS fading channel simulator capable of simulating diverse fading characteristics for a satellite channel was designed and tested to yield various performance measures such as symbol error rate and average bit error rate.<br>Ph.

Full textAbstract:
Quantification of physiological functions with positron emission tomography requires knowledge of the arterial radioactivity concentration. Automated blood sampling systems increase the accuracy of this measurement, particularly for short-lived tracers such as oxygen-15, by reducing the sampling interval to a fraction of a second. They, however, require correction for tracer delay between the arterial puncture site and the external radiation detector (external delay), and for the tracer bolus distortion in the sampling catheter (external dispersion).<br>We have evaluated and implemented the "Scanditronix" automated blood sampling system and measured its external delay and dispersion. PET studies of cerebral blood flow and oxygen metabolism using simultaneous manual and automated blood sampling were analyzed and compared. We show that the results obtained with automated blood sampling are more reliable than those based on manual sampling. We also present suggestions to further improve the reliability of quantitative PET studies based on automated blood sampling.

Full textAbstract:
Contaminated land can pose risks to human health, buildings and the environment. In principle, the regulatory mechanisms already exist in the UK to minimize the risks that can arise from the redevelopment and use of contaminated sites. However there is known to be wide variation in way the redevelopment of contaminated land has been controlled by various regulatory authorities. This thesis examines the control system for the redevelopment of contaminated land in the UK and assessesh ow and why variation in regulatory standards occurred. The empirical investigation is based on a comparative case study methodology. Four regulatory regimes, representing contrasting standards of regulation have served as case studies. The focus of the study is the redevelopment of former gasworks sites as it is common for such sites to be contaminated with harmful substances such as coal tar, phenols, spent oxide, cyanide, sulphur and asbestos. The recommended procedures and activities presented in official policy and guidance notes provide a benchmark for the assessment of regulatory practice. For an analysis of variation this thesis uses a theoretical framework developed from a critical review of the main approaches within the policy implementation literature and insights from organizational studies. The regulatory regime is complex and effective regulation requires input, and action, by various technical experts. For this reason the research, empirically and theoretically, focuses primarily on the linkage, and/or relationship between expert knowledge, communication and action for explanations of variation. The thesis argues that the level of commitment by individual regulatory experts and officers to the policy aims was a critical factor in explaining the variation in the standards of regulation. Moreover, for those redevelopments where contaminated land had been raised as an issue by certain institutional actors then regulatory performance was good

Full textAbstract:
The continuing deterioration of land and water resources occurring in several regions of the world is partly as a result of the mismatch between land suitability or capability and land use. Failure to achieve a perfect match between land capability and use can be particularly problematic for agricultural production because cultivating the wrong crops on wrong soils can only result in poor yields and its associated financial and other losses. There is therefore, a pressing need for effective land evaluation through better matching of land characteristics with land use to achieve optimal utilisation of available land resources for sustainable agricultural production. As far as agriculture is concerned such an exercise will result in defining which part of an area is suitable for particular crops, based on the available land resources and other production inputs, and which parts are better left for other uses. In this study, a land evaluation system for predicting the physical suitability of land for key crops, namely Wheat, Barley and Olive in the north west of Libya was developed based on matching land use requirement for these crops with the available land resources in the area. It involved a modelling strategy based on Boolean and Fuzzy logic sets, implemented within a Geographic Information System (GIS) environment. While the Boolean method assumes that the attributes of a given soil type are known with certainty and the boundaries between soil types are clearly defined, Fuzzy logic can be used to accommodate uncertainties in the available knowledge on these attributes through the use of membership functions. The GIS-based models developed comprise four layers; namely, soil, climate, slope and erosion hazard all of which have been shown directly influence land suitability for agricultural production. This resulted in the classification of the soil into 4 suitability classes, i.e. high suitability, moderate suitability, marginal suitability and not suitable. The results show that for Barley for example 52% of the soil in the north western Libya is highly suitable using Fuzzy approach while the corresponding figure for the Boolean is 62%. The two approaches were compared on cell by cell basis using map agreement. The comparison shows that there were reasonable agreements in evaluations by the two approaches for barley, wheat and olive of 51%, 46% and 56% respectively.

Full textAbstract:
The application of advanced robotics to surgical tasks can help to improve the delivery and quality of treatment, reduce the cost of surgery, and increase safety. Despite these advantages, robots have not found their niche in the surgical setting to the extent that they have in many industries. For the health care industry and society to reap the benefits offered by advanced surgical robots, technological challenges related to the application of advanced surgical robots to surgical tasks must be met, and the barriers to clinical acceptance must be overcome.
Surgical retraction is a technique employed in most surgical procedures to expose the anatomical structures of interest to the surgeon. Many problems associated with this common surgical task could be addressed by advanced surgical robots which could be easily repositioned, and could accept a variety of retractors for different applications. Using a robot could liberate surgical assistants for other tasks, and could allow the retraction pressure to be monitored and the surgeon alerted to excessive pressures.
In this thesis two approaches to automated surgical retraction are developed with the overall objective of demonstrating each approach in the surgical setting to determine the feasibility of the approaches as alternatives to current retraction techniques. The first approach involves the development of an automated effector for operating from a pre-robotic platform. Gross positioning of the retractor is performed manually with the pre-robotic device, while the automated effector provides fine positioning control to adjust the surgical exposure, as well as three automated modes of operation: 1) maintaining the retractor position within a desired position window, 2) maintaining the retraction pressure within safe limits, and 3) periodically releasing the retraction pressure. The second approach involves the development of an advanced surgical robot for retraction that provides both gross and fine positioning, as well as the automated modes of operation. In contrast to the first system, this system is fully robotic.
This thesis describes the development of two systems based on these approaches. As a significant part of the development, a new physiologic sensor was developed for monitoring the retraction pressure. A model of retraction pressures was established based on measurements made during hip replacement and abdominal surgeries. Using this model, an improved retraction pressure sensor with multiple sensing sites was developed, and control algorithms for automating retraction were developed. As part of the system development, requirements for an operator interface were identified and a versatile operator interface system was adapted and integrated into the robotic system to provide intuitive control. An important part of the work involved the identification of the crucial need for a safety standard for surgical robots, and the further identification of the critical issues that such a standard would have to address. From this, a set of general design requirements for surgical robots was developed, and specific approaches for addressing the safety issues in a prototype of an advanced surgical robot for retraction were developed and integrated into the systems.
The feasibility of each approach was demonstrated during successful surgical trials of the automated pre-robotic system and the advanced surgical robot during abdominal surgery. A comparative evaluation of the systems, in terms of quality of treatment, costs and payback, and safety, led to an identification of advantages that each approach offered and of problems associated with the implementations.

Full textAbstract:
It is illegal to pass a stopped school bus when the vehicleâ s stop-arm is extended and the red lights are flashing. Public opinion on this issue is very clear. A random phone survey of the public conducted by the National Highway Traffic Safety Administration (NHTSA) reported that more than 90 percent of respondents rated â passing a school bus that has its red lights flashing and the stop arm in full viewâ as a somewhat or extremely dangerous driving behavior (Boyle, Dienstfrey, and Sothoron, 1998). Despite this public opinion, there is evidence that the number of vehicles that illegally pass school buses each day is substantial. Based on data collected throughout the state of Illinois, the Illinois Department of Transportation (1996) estimated that more than 10,000 vehicles illegally pass school buses every day. Similar findings were reported in Florida (Center for Urban Transportation Research, 1996).
To address this problem, NHTSA sponsored a research effort aimed at developing an automated system for detecting and recording the license plates of vehicles as well as their drivers who illegally pass school buses. The overall objective of this research was to develop a prototype system that would automatically detect and record vehicles that illegally pass school buses (i.e., busâ stop-arm is extended and lights are flashing). Based on the results of technical, administrative, and legal feasibility analyses, system specifications were developed and a prototype unit was built. The prototype system was then field-tested in a variety of real-world conditions in both a controlled setting and on an actual school bus route. The results of the field test proved the prototype system to be comparable with other automated enforcement systems. Testing showed that recorded images were more identifiable when the violation occurred in the lane next to the school bus. In addition, frontal facial recordings were found to be 1.5 times more useful then profile recordings. It must be stressed that the purpose of the field test was to gather data that could be used in support of design recommendations and changes for the next generation of the system.<br>Master of Science

Full textAbstract:
This research was designed to develop and evaluate an automated alternative to the Box-Jenkins method of forecasting. The study involved two major phases. The first phase was the formulation of an automated ARIMA method; the second was the combination of forecasts from the automated ARIMA with forecasts from two other automated methods, the Holt-Winters method and the Stepwise Autoregressive method. The development of the automated ARIMA, based on a decision criterion suggested by Akaike, borrows heavily from the work of Ang, Chuaa and Fatema. Seasonality and small data set handling were some of the modifications made to the original method to make it suitable for use with a broad range of time series. Forecasts were combined by means of both the simple average and a weighted averaging scheme. Empirical and generated data were employed to perform the forecasting evaluation. The 111 sets of empirical data came from the M-Competition. The twenty-one sets of generated data arose from ARIMA models that Box, Taio and Pack analyzed using the Box-Jenkins method. To compare the forecasting abilities of the Box-Jenkins and the automated ARIMA alone and in combination with the other two methods, two accuracy measures were used. These measures, which are free of magnitude bias, are the mean absolute percentage error (MAPE) and the median absolute percentage error (Md APE).

Full textAbstract:
Multimodal machine learning is a subfield of machine learning that aims to relate data from different modalities, such as texts and images. One of the many applications that could be built upon this technique is an image retrieval system that, given a text query, retrieves suitable images from a database. In this thesis, a retrieval system based on canonical correlation is used to suggest images for news articles. Different dense text representations produced by Word2vec and Doc2vec, and image representations produced by pre-trained convolutional neural networks are explored to find out how they affect the suggestions. Which part of an article is best suited as a query to the system is also studied. Also, experiments are carried out to determine if an article's date of publication can be used to improve the suggestions. The results show that Word2vec outperforms Doc2vec in the task, which indicates that the meaning of article texts are not as important as the individual words they consist of. Furthermore, the queries are improved by rewarding words that are particularly significant.

Full textAbstract:
Container Terminals are experiencing increased pressure to raise their productivity levels and capacity, in order to handle the increasing amounts of container cargo due to globalization. Due to space restrictions and other financial factors, automated solutions have been developed. AGVs (Automated Guided Vehicles) are one of those automated solutions for the horizontal transportation with in a Container Terminal. A recent European sponsored project has lead to the development of a new generation of AGVs that are using cassettes namely IPSI™ AGVs. An agent-based simulator has been developed with the purpose of constructing and evaluating dispatching strategies for this new developed AGV system. Already explored dispatching strategies [9, 14] are used with additional modifications to re-evaluate them with the consideration of the usage of cassettes. Our findings from the simulation experiment are suggesting that a cost estimation based approach is much more suited than an inventory based. In addition to that, the results are very convincing in that the number of cassettes used is the most dominate factor despite dispatching strategy for obtaining a fast ship turnaround time.

Full textAbstract:
All land uses affect storm water runoff However, different uses of the same site generate varying amounts of runoff Many communities have come to rely upon detention and/or retention basins for controlling the additional runoff resulting from land development. It is argued that this incremental approach to storm water management must be replaced with a more proactive long-term view.To achieve this, more user-friendly software capable of modeling the effect long-range land use plans have on the volume and behavior of storm water runoff is needed. This software, called a Spatial Decision Support System (SDSS), must be capable of guiding the user, who may not be an expert at runoff analysis, through the process and also capable of generating output in various formats understandable by lay persons. This study utilizes a systems analysis technique to develop a theoretical framework for the Storm Water SDSS.<br>Department of Urban Planning

Full textAbstract:
The aim of the study was to evaluate an automated tracking system and its possibilities to increase knowledge and awareness (future described as educate) in game intelligence among Swedish male elite football players. The study involved both qualitative and quantitative aspects. The quantitative part consisted of observing offensive passes performed by three male players, average age 25.3 (±1.5) years, weight 75.7 (±2.1) kg and height 181 (±4.4) cm. All of the players offensive passes were judged and categorized, based on criteria by the practitioner with footballing knowledge and by the automated tracking system. Pass probability (PP) and pass probability times pass impact (PP x PI) was observed since they indicate the possibility for a pass to succeed but also its impact, which could be associated with the game intelligence ability, knowledge of situational probability. The results showed a significant association (p<0.05) between PP and PP x PI. Hence, the null hypothesis could be rejected. Additionally, pass probability (PP) was a more accurate method than pass probability times pass impact (PP x PI) and results also showed that the players made more accurate decisions than the automated tracking system. The qualitative part of the study consisted of three recorded sessions with the player, where the automated tracking system was used as an educational tool. The players were shown different situations which they then discussed. Results indicated that most of the player quotes could be associated to visual search behavior (n=24). Although, an improved automated tracking system was used, there are still limitations with the automated tracking systems accuracy which could affect the results. This article provides a very preliminary step in the study of automated tracking systems as an educational tool and suggests an approach based on discussions with players, rather than only relying on answers given by the automated tracking system. However, the research area within automated tracking systems is relatively unexplored and results should be interpreted with caution. Therefore, future studies are necessary to determine how much an automated tracking system could improve game intelligence.

Full textAbstract:
Maintaining and operating manual main distribution frames is labour-intensive. As a result, Automated
Main Distribution Frames (AMDFs) have been developed to alleviate the task of maintaining
subscriber loops. Commercial AMDFs are currently employed in telephone exchanges in some parts
of the world. However, the most significant factors limiting their widespread adoption are costeffective
scalability and reliability. Therefore, an impelling incentive is provided to create a simulation
framework in order to explore typical implementations and scenarios. Such a framework will
allow the evaluation and optimisation of a design in terms of both internal and external redundancies.
One of the approaches to improve system performance, such as system reliability, is to allocate the
optimal redundancy to all or some components in a system. Redundancy at the system or component
levels can be implemented in one of two schemes: parallel redundancy or standby redundancy. It is
also possible to mix these schemes for various components. Moreover, the redundant elements may
or may not be of the same type. If all the redundant elements are of different types, the redundancy
optimisation model is implemented with component mixing. Conversely, if all the redundant components are identical, the model is implemented without component mixing.
The developed framework can be used both to develop new AMDF architectures and to evaluate
existing AMDF architectures in terms of expected lifetimes, reliability and service availability. Two
simulation models are presented. The first simulation model is concerned with optimising central
office equipment within a telephone exchange and entails an environment of clients utilising services.
Currently, such a model does not exist. The second model is a mathematical model incorporating
stochastic simulation and a hybrid intelligent evolutionary algorithm to solve redundancy allocation
problems.
For the first model, the optimal partitioning of the model is determined to speed up the simulation
run efficiently. For the second model, the hybrid intelligent algorithm is used to solve the redundancy
allocation problem under various constraints. Finally, a candidate concept design of an AMDF is
presented and evaluated with both simulation models.<br>Dissertation (MEng)--University of Pretoria, 2013.<br>gm2014<br>Electrical, Electronic and Computer Engineering<br>unrestricted

Full textAbstract:
A society´s health depends on the access to proper and hygiene sanitation. Half of the population still do not have access to proper sanitation in Nepal; therefore government and non-government organizations are facilitating sanitation access to all the population. Decades ago, open defecation and pit latrines toilet were the only options as sanitation system to the people. But now, various types of toilets system known as dry toilets, septic tanks, centralized sewerage system and biogas integrated toilets are available. Therefore, existing toilet system in rural areas of Nepal needs to be evaluated with respect to environment and long term sustainability. Aim of this study is to find the appropriate toilet system for rural areas of Nepal. This study also discusses how that appropriate toilet system can be promoted based on current scenarios from government level to local level. Generic Multi-Attribute Analysis (GMAA) is used as a decision support tools to evaluate available various toilet alternatives. For which a rural area from Nepal is chosen as study area. GMAA helps in evaluating all the toilet system based on social, technological, environmental and economical aspects. Interpretation between the toilet systems can be made easily with the help of GMAA results. Field questionnaire survey was also carried out in the study area to know user´s understanding of toilet alternatives. Every toilet systems have pro and cons based on different social, technological, environmental and economical aspects. It was found that pit latrines toilet systems are mostly practiced in the rural areas of Nepal. User prefers pit latrines because of its social accepted character and technologically easy in using it. Biogas integrated toilet system came as optimal toilet system though not accessible to all household. It was found that urine and faeces separating toilets are environmentally and economically beneficial. The thesis concludes that appropriate toilet system which is sustainable must be promoted while increasing toilet coverage in Nepal. Urine and faeces separating toilet is found to be appropriate and need to be incorporated in the government goal of increasing toilet coverage.

Full textAbstract:
An aging population is one common challenge faced by many developed countries including Australia. The Australian government has realised that the existing healthcare system must be improved to provide better support longer-term for the healthcare needs of this population. This research examines one such opportunity by suggesting a reform on how the care needs of residents living in Australian residential aged care facilities (RACF) are assessed. A recent study has shown that the current assessment system, known as the Residential Classification Scale (RCS), is subjected to high administrative procedural overhead costs and significant deviations in assessment results. This thesis documents a technical feasibility study of a novel method aimed to solve issues related to the time demands and subjectivity of the RCS through the design and implementation of a Wireless Sensor Network (WSN). This WSN is engineered to unobtrusively collect data from wireless sensor nodes either embedded in the RACF environment or attached to the resident??s body. The collected data can be potentially used to provide automatic and accurate care level assessments for the resident. The methodology of preparing and conducting the experiments to prove the hypotheses is justified and described, including the experimental instruments and procedures involved. The results show that this WSN surpasses similar research systems in terms of its application scale, the number and types of sensor nodes involved and the complexity of its hardware and firmware architectures. The major contributions of this thesis are: ?? The WSN developed satisfies certain technical requirements to be declared fit for use in a mock Australian RACF. ?? The WSN provides high sensor detection accuracies (between 88% and 100%), superior location tracking capability (94.75%) and activities of daily living inference capability over similar studies. Opportunities for further improvements of this WSN include: ?? Fine tuning the detection accuracy of Passive Infra-red (PIR) motion sensors. ?? Minimising the down time of the sensor nodes due to firmware memory leak. ?? An extra location tracking mechanism to improve location accuracy determination.

Thesis (MScConsEcol)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: Wetland systems provide vital hydrological ecosystem goods and services to mankind. When wetlands are transformed, through invasion by alien plants or replaced with agriculture, natural capital is lost, and the system is no longer able to provide the same quality of hydrological ecosystem services. Natural capital can be restored, but it involves substantial financial investment, and there is no guarantee that these hydrological ecosystem services will be fully recovered. This thesis aimed to investigate the hydrological impact of the land-cover changes in the Kromme River Catchment over the last 50 years, by using a combination of mapping and hydrological modelling techniques. We hypothesized that wetland loss in the Kromme has resulted in a shift in the flow regime, greater responsiveness to floods as a result of less storage, lower baseflow, and reduced water quality. We also hypothesised that the riparian invasion by Acacia mearnsii has caused flow reductions as a result of increased evaporation relative to the wetlands. Modelling results predict that over the past 50 years, the transformation of the floodplain wetlands in the Kromme River has shifted the flow regime, reducing baseflows and increasing the responsiveness of the catchment to extreme rainfall events. The invasion of A. mearnsii over time has also been predicted to have caused a reduction in river flow. Various restoration scenarios were considered, however if the Kromme were to be restored back to a land-cover state comparable to the 1950’s, 26.9 km2 (65.1%) of A. mearnsii would have to be cleared, and 5.2 km2 (34.2%) of the wetlands would have to be restored. The hydrological benefits would include a predicted increase in riverflow (42 mm/a), baseflow (2.9 mm/a), an increase in flood protection and improved water quality. This restoration strategy could be regarded as a type of insurance plan, and the benefits gained in terms of increased ecosystem service delivery would be the insurance premium. In conclusion it appears that restoration, insuring natural capital in the Kromme River, would provide significant economic returns on investment.<br>AFRIKAANSE OPSOMMING: Moeraslandstelsels voorsien die mens van noodsaaklike hidrologiese ekosisteemgoedere en -dienste. Wanneer moeraslande verander word, hetsy deur die indringing van uitheemse plante of vervanging met landboubedrywighede, gaan natuurlike kapitaal verlore en kan die stelsel nie meer dieselfde gehalte hidrologiese ekosisteemdienste lewer nie. Hoewel natuurlike kapitaal herwin kan word, behels dit beduidende finansiële belegging, en is daar boonop geen waarborg dat die hidrologiese ekosisteemdienste ten volle sal herstel nie. Hierdie tesis het ten doel gehad om die hidrologiese impak van die grondbedekkingsveranderinge in die Krommerivier-toeloopgebied oor die afgelope 50 jaar met behulp van ’n kombinasie van karterings- en hidrologiese modelleringstegnieke te ondersoek. Die hipotese was dat moeraslandverlies in die Kromme tot ’n verandering in die vloei-regime, hoër responsiwiteit op erge reënval as gevolg van minder bergingsruimte, ’n laer basisvloei en swakker watergehalte gelei het. Daar is voorts gehipoteseer dat die oewerindringing deur Acacia mearnsii ’n verlaging in vloei veroorsaak het weens ’n toename in verdamping uit die moeraslande. Modelleringsresultate dui daarop dat die transformasie van die vloedvlakte-moeraslande in die Krommerivier oor die afgelope 50 jaar die vloei-regime verander het, basisvloei verminder het en die toeloopgebied se responsiwiteit op erge reënval verhoog het. Die indringing van A. mearnsii het ook volgens aanduidings mettertyd ’n vermindering in riviervloei tot gevolg gehad. Verskeie herstelscenario’s is oorweeg. Om die grondbedekking in die Kromme te herstel tot wat dit in die 1950’s was, moet 26,9 km2 (65,1%) van die A. mearnsii verwyder en 5,2 km2 (34,2%) van die moerasland herwin word. Die hidrologiese voordele kan ’n verwagte toename in riviervloei (42 mm/a) en basisvloei (2,9 mm/a), ’n toename in vloedbeskerming sowel as beter watergehalte insluit. Hierdie herstelstrategie kan as ’n soort versekeringspolis beskou word, en die voordele verbonde aan beter ekosisteemdienslewering as die versekeringsuitbetalung. Ten slotte blyk dit dat die herstel van die Kromme, en die gepaardgaande versekering van natuurlike kapitaal, beduidende ekonomiese opbrengste op belegging sal meebring.

O Brasil desde o período colonial caracteriza-se pela estrutura fundiária concentrada. Em decorrência disso, a partir da década de 30, leis e políticas que visam promover uma reforma agrária vêm sendo elaboradas até os dias atuais. Atualmente, funcionam no Brasil dois modelos de reforma agrária, um baseado em desapropriações de terras improdutivas (reforma agrária tradicional) e outro que se caracteriza pela aquisição de terras por meio do mercado (reforma agrária de mercado). Ambos os modelos têm como objetivos centrais desconcentrar a estrutura produtiva e assegurar o bem estar das famílias e dos trabalhadores que fazem uso da terra. Neste sentido, este trabalho teve por objetivo estimar os impactos no bem-estar das famílias beneficiadas pela reforma agrária de mercado no Brasil, especificamente o Programa Nacional de Crédito Fundiário, em sua linha de financiamento Consolidação da Agricultura Familiar que opera na região sul do Brasil. Os impactos foram estimados com uma amostra de tratamento (beneficiários) e controle (não beneficiários), em que os indivíduos foram entrevistados nos anos de 2007 (baseline) e 2010 (follow-up), configurando uma estrutura de dados longitudinais. Esta estrutura dos dados permitiu estimar os impactos do programa pelo método da dupla diferença. Métodos para verificar a presença e controlar os possíveis vieses amostrais (viés de seleção e viés de atrito) foram utilizados com a finalidade dar confiabilidade as estimativas e garantir que os impactos se devem a intervenção do programa. Os resultados mostraram impactos positivos e estatisticamente significantes para as variáveis de impacto renda familiar total, renda familiar total per capita e patrimônio total. O presente trabalho constatou, também, um aumento significativo na proporção das famílias beneficiadas pelo Programa que possuem casa própria após o período de tratamento do programa, mas a infraestrutura da moradia, em termos de acesso à rede coletora de esgoto, acesso à água e energia elétrica não mudou entre os períodos analisados. Neste sentido, há indícios que a linha de financiamento Consolidação da Agricultura Familiar na região Sul do Brasil gerou impactos positivos no bem-estar das famílias beneficiadas.<br>Since it was a colony, Brazil has presented a very concentrated land property structure. From the 30s on, laws and politics have been developed in order to promote an agrarian reform. In the present days, two alternative models of agrarian reform are being applied in Brazil expropriation of non-productive land (traditional model) and acquisition of land by means of the market (market-led agrarian reform). Both approaches seek to reduce land concentration and improve the welfare of families and farmers that use land as a productive factor. In this context, this work aimed at estimating the impact of Programa Nacional de Crédito Fundiário (a program of market based agrarian reform in Brazil) on the welfare of beneficiary families involved in the line of financing called Consolidação da Agricultura Familiar, which operates in the south region of Brazil. The impact of the program on beneficiary families was estimated based on the observation of a treatment and a control samples, from which data was collected in 2007 (baseline) and 2010 (follow up), constituting a longitudinal database. Such data structure allowed the estimation of impact through the double difference method. Sampling biases (selection and attrition) were controlled in order to avoid confounding effects and enhance internal validity of the results. The findings indicated positive and significant impacts on total family income, total per capita family income and total assets. Among beneficiaries, there was also a significant increase in the proportion of families that own their houses. Notwithstanding, no improvements in infrastructure conditions (sewage, water and electricity network access) were observed. In general terms, the findings indicate that the Programa Nacional de Crédito Fundiário in its line Consolidação da Agricultura Familiar in the South region of Brazil has generated positive impacts on the welfare of beneficiary families.

Full textAbstract:
Un système est défini par les entités et leurs interrelations dans un environnement qui est déterminé par une limite arbitraire. Les systèmes complexes présentent un comportement émergent sans un contrôleur central. Les systèmes concrets désignent ceux qui sont observables dans la réalité. Un modèle nous permet de comprendre, de contrôler et de prédire le comportement du système. Un modèle différentiel à partir d'un système pourrait être compris comme une sorte de loi physique sous-jacent représenté par l'un ou d'un ensemble d'équations différentielles. Ce travail vise à étudier et mettre en œuvre des méthodes pour effectuer la modélisation des systèmes automatisée par l'ordinateur. Cette thèse pourrait être divisée en trois étapes principales, ainsi: (1) le développement d'un solveur numérique automatisé par l'ordinateur pour les équations différentielles linéaires, partielles ou ordinaires, sur la base de la formulation de matrice pour une personnalisation propre de la méthode Ritz-Galerkin; (2) la proposition d'un schème de score d'adaptation qui bénéficie du solveur numérique développé pour guider l'évolution des modèles différentiels pour les systèmes complexes concrets; (3) une implémentation préliminaire d'une application de programmation génétique pour effectuer la modélisation des systèmes automatisée par l'ordinateur. Dans la première étape, il est montré comment le solveur proposé utilise les polynômes de Jacobi orthogonaux comme base complète pour la méthode de Galerkin et comment le solveur traite des conditions auxiliaires de plusieurs types. Solutions à approximations polynomiales sont ensuite réalisés pour plusieurs types des équations différentielles partielles linéaires, y compris les problèmes hyperboliques, paraboliques et elliptiques. Dans la deuxième étape, le schème de score d'adaptation proposé est conçu pour exploiter certaines caractéristiques du solveur proposé et d'effectuer l'approximation polynômiale par morceaux afin d'évaluer les individus différentiels à partir d'une population fournie par l'algorithme évolutionnaire. Enfin, une mise en œuvre préliminaire d'une application GP est présentée et certaines questions sont discutées afin de permettre une meilleure compréhension de la modélisation des systèmes automatisée par l'ordinateur. Indications pour certains sujets prometteurs pour la continuation de futures recherches sont également abordées dans ce travail, y compris la façon d'étendre ce travail à certaines classes d'équations différentielles partielles non-linéaires<br>A system is defined by its entities and their interrelations in an environment which is determined by an arbitrary boundary. Complex systems exhibit emergent behaviour without a central controller. Concrete systems designate the ones observable in reality. A model allows us to understand, to control and to predict behaviour of the system. A differential model from a system could be understood as some sort of underlying physical law depicted by either one or a set of differential equations. This work aims to investigate and implement methods to perform computer-automated system modelling. This thesis could be divided into three main stages: (1) developments of a computer-automated numerical solver for linear differential equations, partial or ordinary, based on the matrix formulation for an own customization of the Ritz-Galerkin method; (2) proposition of a fitness evaluation scheme which benefits from the developed numerical solver to guide evolution of differential models for concrete complex systems; (3) preliminary implementations of a genetic programming application to perform computer-automated system modelling. In the first stage, it is shown how the proposed solver uses Jacobi orthogonal polynomials as a complete basis for the Galerkin method and how the solver deals with auxiliary conditions of several types. Polynomial approximate solutions are achieved for several types of linear partial differential equations, including hyperbolic, parabolic and elliptic problems. In the second stage, the proposed fitness evaluation scheme is developed to exploit some characteristics from the proposed solver and to perform piecewise polynomial approximations in order to evaluate differential individuals from a given evolutionary algorithm population. Finally, a preliminary implementation of a genetic programming application is presented and some issues are discussed to enable a better understanding of computer-automated system modelling. Indications for some promising subjects for future continuation researches are also addressed here, as how to expand this work to some classes of non-linear partial differential equations

碩士<br>中國文化大學<br>資訊管理研究所<br>95<br>As the applications of Internet and the fashion of world wide web and the technol-ogy for developing website becoming mature, the number of websites grows with a sur-prising speed. But the lower threshold of website construction also means that the qual-ity of websites can vary drastically since many websites are built by amateurs with little experience. Many factors affect the management performance of the website. Website quality evaluation is thus becoming an important subject.
The intentions of this research go deep into analyzing and developing a set of cri-teria suitable for evaluating the quality of shopping websites; build evaluation criteria for shopping websites by literature review as well as interviews with experts question-naire survey and real-site evaluation. Design evaluation criteria and relative weight, to investigate the satisfaction rate of the automated website evaluation system(AWES) that was developed according to the evaluation criteria. Basis consulted to assist web de-signers for design and a tool for analyzing websites, and possible improvements for a website.
The results showed that evaluation criteria for shopping website include five major groups: “shopping functions” , “interactive functions” , “website management func-tions” , “administrative tool functions” and “multimedia use functions”. These groups could be further divided into 37 evaluation factors. And then AWES as compared with human inspection result, as well as to compare their differences, data extraction and evaluation accuracy of system. The experimental results are promising and the system has demonstrated its practicability as a great automated website evaluation system.
