In this thesis we design and simulate OFDM (Orthogonal Frequency Division Multiplexing) to study the performance of the OFDM system at higher order modulation schemes. It is very important to evaluate performance of the communication system, to test the efficiency and quality of the service it can provide. We used Matlab program to design the functionality of OFDM, then BER (Bit Error Rate) is obtained to different SNR (Signal to Noise Ratio) values, for M-array PSK and M-array QAM modulations techniques. BER is widely used as performance measurement tool, it tells number of bits destroyed while the data is travelling from source to the destination, AWGN (Additive White Gaussian Noise) is used as transmission channel.

Abstract A stochastic model for orderbook dynamics is proposed in Cont et al.(2010) and empirically evaluated in thisthesis. Arrival rates of limit, marketand cancellation orders are described interms of a Markov chain where thearrival rates are exponentiallydistributed. The model not onlyconsiders the best bid and ask queuesbut also additional price levels of theorder book. Methods for computingseveral quantities important to highfrequency trading are proposed usingLaplace transforms and continuedfractions. These quantities includeconditional probabilities such as theprobability of a price increasedepending on the profile of the orderbook. Computing these probabilities aresupposed to be easy enough to computeanalytically. However this was not thecase. We failed in the inversion of theLaplace transform methods and the mainreason is that the instructions in Contet al. (2010) are not adequate when itcomes to perform the inversion. Hence wedraw the conclusion that the method isno good for predicting short termbehavior of limit order books. For longterm applications the model can be usedto simulate the order book with goodresults.

With the advent of high-speed computation and the desire to analyze increasingly complex behavior in power systems, simulation techniques are gaining importance and prevalence. However, while simulations of large, interconnected power systems are feasible, they remain time-consuming. Additionally, the models and parameters used in simulations are uncertain, due to measurement uncertainty, the need to approximate complex behavior with low-order models and the inherent changing nature of the power system. This thesis explores the use of model reduction techniques to enable the study of uncertainty in large-scale power system models. The main goal of this thesis is to demonstrate that uncertainty analyses of transient simulations of large, interconnected power systems are possible. To achieve this, we demonstrate that a basic three stage approach to the problem yields useful results without significantly increasing the computational burden. The first stage is to reduce the order of the original power system model, which reduces simulation times and allows the system to be simulated multiple times in a reasonable time-frame. Second, the mechanics of the model reduction are closely studied; how uncertainties affect the reduction process and the parameters in the reduced-order model as well as how the process of reduction increases uncertainty are of particular interest. Third, the reduced-order model and its accompanying uncertainty description are used to study the uncertainty of the original model. Our demonstration uses a particular model reduction technique, synchronic modal equivalencing (SME), and a particular uncertainty analysis method, the probabilistic collocation method (PCM). Though our ideas are applicable more generally, a concrete demonstration of the principle is instructive and necessary. Further, while these particular techniques are not relevant to every system, they do apply to a broad class of systems and illustrate the salient features of our methodology. As mentioned above, a detailed analysis of the model reduction technique, in this case SME, is necessary. As an ancillary benefit of the thesis work, interesting theoretical results relevant to the SME algorithm, which is still under development, are derived.

Annotation:

It is increasingly common for complex social, economic and environmental policy concerns to be delivered via funded community-based projects. A project’s contribution is typically monitored and evaluated relative to pre-defined outcomes, supported by a set of indicators. Available research suggests that when judged against such criteria, the performance of many funded international developmental and community-based sustainability (CBS) projects are variable, with evidence suggesting that changes elicited are negligible in duration, type, and scale. However, evaluating project performance relative to pre-defined outcomes may overlook the practical learning accumulated by actors in realising key objectives under conditions afforded by the operational context. To address this gap, developmental evaluation (DE) foregrounds and supports project practitioner learning and innovation under dynamic, complex, and uncertain operating conditions. Applying the DE focus on project actor learning and innovation, the present research thematically analyses how practitioners in a funded CBS case study project make sense of their practice. Despite its explicit focus on learning however, DE has not articulated a coherent cognitive paradigm, and a contribution of the present study is to equip DE with a conceptual architecture drawn from the enactive cognitive science paradigm, rooted in an explicit accounting of complexity. Using this base, a prototype DE framework was designed and provisionally field-tested in the form of a set of prompts to be used with CBS practitioners to augment traditional monitoring and evaluation activities. This framework is intended to support practitioners in surfacing and capturing second-order learning about their practices and to explore opportunities for innovative responses to dynamic complex operational conditions. Recommendations are offered for further research and how these findings might be incorporated into future CBS design and funding considerations.

En utilisant la théorie du Groupe de Renormalisation on peut prédire les valeurs de certaines quantités physiques (dites universelles) ; parmi elles on compte les exposants critiques des transitions de phase du deuxième ordre. Plusieurs méthodes théoriques peuvent être utilisées pour calculer des quantités universelles ; la méthode la plus précise est le développement perturbatif à dimension fixe (proposé par G. Parisi). Avec cette méthode, Nickel et al. Ont calculé vers la fin des années '70 les exposants critiques jusqu'au niveau de six boucles (et, plus récemment, un sous-ensemble des contributions à sept boucles). Dans ce travail de thèse, nous montrons comment automatiser le calcul sur ordinateur; du fait de la complexité du développement perturbatif, on ne peut espérer paramétrer et calculer les exposants critiques au niveau de sept boucles complètes qu'avec l'ordinateur. En particulier, nous présentons une technique générale pour paramétrer le développement perturbatif à n'importe quel ordre (déjà testé avec succès au niveau sept boucles complètes); même si le travail n'a pas encore été complété, cette technique (utilisée conjointement avec des algorithmes pour l'intégration automatique multidimensionnelle) nous a déjà permis de reproduire un sous-ensemble important des calculs précédents
Making use of Renormalization-Group theory, one can make predictions for values taken by some physical quantities (called universal); among them we have the critical exponents of second-order phase transitions. A lot of different theoretical methods can be used to calculate universal quantities; the most precise one is the pertirbative development at fixed dimension (originally proposed by G. Parisi). Making use of this method, Nickel and coworkers were able to calculate by the end of the 70's critical exponents up to six-loop level (and, more recently, a subset of seven loops). In our thesis we show how to automatize all the calculations by means of the computer; in fact, due to the complexity of the perturbative development only making use of the computer we can hope to parametrize and compute critical exponents up to full seven-loop level. In particular, we present a general technique to parametrize perturbative development to an arbitrary order (already tested with success at full seven-loop level); even if the work has not yet been completed, this technique (together with algorithms for automated multidimensional integration) has already allowed us to reproduce a substantial subset of previous calculations

Annotation:

A stochastic model for the dynamics of a limit order book is evaluated and tested on empirical data. Arrival of limit, market and cancellation orders are described in terms of a Markovian queuing system with exponentially distributed occurrences. In this model, several key quantities can be analytically calculated, such as the distribution of times between price moves, price volatility and the probability of an upward price move, all conditional on the state of the order book. We show that the exponential distribution poorly fits the occurrences of order book events and further show that little resemblance exists between the analytical formulas in this model and the empirical data. The log-normal and Weibull distribution are suggested as replacements as they appear to fit the empirical data better.

Annotation:

Both nationally and at the state level, educational reform is focusing on the improvement of classroom instruction. Recently, Washington State enacted the Teacher/Principal Evaluation Pilot (TPEP) to define evaluation criteria intended to measure effective professional practices, including classroom instruction. This exploratory survey study sought to describe the perceptions of Washington State elementary principals regarding their professional development needs for implementation of the new evaluation criteria. The survey consisted of 5 parts totaling 25 questions and was disseminated to 1,897 elementary principals with a return rate of 354. While the state effectively disseminated initial information about the evaluation criteria through local Educational Service Districts (ESDs), some policy inconsistency appears to have developed between the school district and building level in terms of implementation support for principal leadership activities, learning behaviors, and preferred learning topics. Responses indicated that principals rarely engage in social learning activities that would prepare them as a group to consistently and reliably interpret the criteria on the evaluation. Also, few principals identified a strong desire to learn about collaborative structures within their school, which increases concerns about the sustainability of the TPEP policy, because of the need to develop shared understandings of the language and the expectations. Fostering such an understanding may comprise the next phase of development.

Annotation:

Sensorless control of the synchronous reluctance motor has been a topic of research for more than a decade, producing several successful methods to accomplish this goal. However, a technique that has been overlooked is the full-order nonlinear observer, which is essentially a software model of the motor driven by measurements from the actual motor. Presented in this thesis is the design, implementation, and experimental testing of a full-order observer-based sensorless control technique which requires only the phase current and voltage measurements that are typically available in standard three-phase inverters. A technique is also presented for calculating a table of observer feedback gains parameterized only by the steady-state motor speed. This allows a gain-scheduling observer to be implemented which, as shown using experiments, improves the transient response of the observer over a wide speed range. The sensorless controller consists of a full-order nonlinear observer coupled with an input-output linearization speed controller. The resulting controller was implemented in Simulink and executed on a dSPACE DS1103 real-time DSP board using the Real-Time Workshop extension to Simulink. A custom built three-phase IGBT inverter was used to interface the DSP to a 100 watt synchronous reluctance motor for laboratory testing. The resulting sensorless controller was able to successfully track a varying speed reference from 150 rpm to 1800 rpm with a tracking error under 5% for most of the speed range. At the lowest speeds, the tracking error begins to increase but the observer remains stable down to 150 rpm.

Annotation:

Dinah Craik is generally considered a conservative author of ‘domestic’ literature, yet, as this thesis argues, she wrote forthrightly on the key socio-political topics of the day, almost invariably challenging the mainstream viewpoint. Drawing from a broad range of Craik’s journalism and fiction, the thesis considers in particular how the reconfiguration of gender boundaries suggested in her work, is radical in its insistence that the requirements for virtue and fulfilment are essentially the same for both sexes. Chapter One examines one of Craik’s periodical articles, ’War-sparkles’ (1855), an exceptional piece of journalism which encapsulates many of the key themes and values defining her work. Chapter Two explores Craik’s representations of masculinity. The hero of John Halifax, Gentleman, is commonly perceived as the product of an over-idealised view of men, but it is clear from the many essays and novels in which she vehemently condemns male conduct, that his portrayal is a reaction against the failure of the middle-classes to live up to the reformist ideals he embodies. Craik’s concept of gentlemanliness is explored further through her use of the figures of the clergyman, doctor, author, and disabled man, each illustrating her engagement with specific contemporary issues central to the construction of masculine identity. Chapter Three considers how Craik’s encouragement of female self-dependence through education and employment, and exposure of the damaging effects of ‘the want of something to do’, openly subverts the prevailing view of marriage as the only path to fulfilment, and reflects her generally pessimistic vision of domestic life. Her portrayals of self-reliant working women provide positive role models for her readers, but also reveal her understanding of the anxieties of single life. Craik’s sympathetic depictions of women who do not conform to the Victorian model of acceptable femininity, whether through physical impairment, race, or ‘fallenness’ are, it is suggested, further evidence of the progressive stance that makes her work so distinctive and compelling.

Annotation:

In analysis of electric field interactions with dielectrics, higher order moments and dielectrophoretic force terms are commonly ignored in what has become known as the dipole approximation. The very few multipolar studies in the literature have either confined analysis to spherical particles or modelled non-spherical particles as spheres of similar dimensions. A major obstacle in analysing the significance of higher order moments has been the limitedness of multipole moment determination techniques. Analytic derivations for higher order moments are only available for spherical particles. This work addresses this roadblock and presents a hybrid numerical-analytical method for determination of the first three effective moments of particles of any shape subjected to electric fields of arbitrary geometry. Results of applying this method for determining higher order dielectrophoretic force terms have been verified by comparison against total force calculations using the Maxwell stress tensor method, known for its mathematical rigorousness in accounting for all interaction between an applied electric field and subject dielectric(s). It is shown that the dipole approximation is particularly unreliable for non-spherical particles, importantly comprising the vast majority of bioparticles. It is shown that higher order terms can constitute up to half the dielectrophoretic force on dielectric particles in suspension. With the current trend toward micro- and nano-electrode geometries used for single particle analysis, and a consequent increase in the number of instances where invoking the dipole approximation can be highly inaccurate, this work offers a computationally inexpensive and verifiably accurate means for determining higher order moments and dielectrophoretic forces.

Annotation:

Guided wave inspection is a form of ultrasonic testing used for non-destructive testing (NDT). Guided waves are capable of propagating long distances bounded by the geometries of the specimen, such as pipes and plates. The technique is commercially used to detect defects in pipelines and is capable of a full volumetric screening many metres (often up to around 100m) from one location. Fundamental axisymmetric wave modes are used to inspect pipelines and are used to quantify defects and features. However, as the technology has progressed, a demand for improving defect sensitivity, spatial resolution and developing the technology into new fields has been recognised. Operating at medium range frequencies is one possibility that could provide the increase in defect sensitivity and spatial resolution required that may not be achieved at low range frequencies. The use of higher order wave modes could also provide additional information useful for defect sizing. Guided wave inspection is a complex ultrasonic technique due to the many wave modes that exist and testing at medium range frequencies requires some challenges to be overcome. The research presented here investigates the potential of using the second order torsional wave mode at medium range frequencies and provides a new sizing technique that for some applications is likely to offer advancement in guided wave inspection and monitoring. The approach firstly included the design and implementation of a setup for analysing the complex signal responses in order to access the higher order torsional wave mode T(0,2) for defect sizing. An efficient method of using FEA has been presented using segmented models to provide the capability of analysing defects with small increment changes that could not be achieved using a full 3D model of the pipe. Using a pipe segment to virtually represent the full pipe also allowed small changes in defect size to be investigated, which would otherwise be extremely difficult to accurately machine experimentally. The FEA modelling technique is also based on broadband signals in comparison to the conventional approach of using narrowband signals and is capable of obtaining a wide frequency spectrum from one model, which significantly reduces the number of models needed to conduct a frequency analysis. Following on from this work, a high density transducer array was developed and compared against a conventional transducer array used in guided wave inspection for the purpose of medium range frequency inspection, which can also be applied to conventional low range frequency inspection. Finally, a new defect sizing method using T(0,2) is presented, which is capable of predicting the depth using peak amplitude responses from spectral analysis and by comparing this to the cut-off frequency of the remaining wall thickness of the defect. The technique has the potential to improve defect sizing, defect sensitivity, increase spatial resolution, and increase the performance of medium range inspection.

In the field of nondestructive evaluation, new and improved techniques are constantly being sought to facilitate the detection of hidden corrosion and flaws in structures such as airplanes and pipelines. In this dissertation, we explore the feasibility of detecting such damages by application of an eddy current based technique and reduced order modeling.

We begin by developing a model for a specific eddy current method in which we make some simplifying assumptions reducing the three-dimensional problem to a two-dimensional problem. (We do this for proof-of-concept.) Theoretical results are then presented which establish the existence and uniqueness of solutions as well as continuous dependence of the solution on the parameters which represent the damage. We further discuss theoretical issues concerning the least squares parameter estimation problem used in identifying the geometry of the damage.

To solve the identification problem, an optimization algorithm is employed which requires solving the forward problem numerous times. To implement these methods in a practical setting, the forward algorithm must be solved with extremely fast and accurate solution methods. Therefore in constructing these computational methods, we employ reduced order Proper Orthogonal Decomposition (POD) techniques which allows one to create a set of basis elements spanning a data set consisting of either numerical simulations or experimental data.

We investigate two different approaches in forming the POD approximation, a POD/Galerkin technique and a POD/Interpolation technique. We examine the error in the approximation using one approach versus the other as well as present results of the parameter estimation problem for both techniques.

Finally, results of the parameter estimation problem are given using both simulated data with relative noise added as well as experimental data obtained using a giant magnetoresistive (GMR) sensor. The experimental results are based on successfully using actual experimental data to form the POD basis elements (instead of numerical simulations) thus illustrating the effectiveness of this method on a wide range of applications. In both instances the methods are found to be efficient and robust. Furthermore, the methods were fast; our findings suggest a significant reduction in computational time.

Annotation:

We present a multifaceted investigation into the relevance of word order in machine translation. We introduce two tools, DTED and DERP, each using dependency structure to detect differences between the structures of machine-produced translations and human-produced references. DTED applies the principle of Tree Edit Distance to calculate edit operations required to convert one structure into another. Four variants of DTED have been produced, differing in the importance they place on words which match between the two sentences. DERP represents a more detailed procedure, making use of the dependency relations between words when evaluating the disparities between paths connecting matching nodes. In order to empirically evaluate DTED and DERP, and as a standalone contribution, we have produced WOJ-DB, a database of human judgments. Containing scores relating to translation adequacy and more specifically to word order quality, this is intended to support investigations into a wide range of translation phenomena. We report an internal evaluation of the information in WOJ-DB, then use it to evaluate variants of DTED and DERP, both to determine their relative merit and their strength relative to third-party baselines. We present our conclusions about the importance of structure to the tools and their relevance to word order specifically, then propose further related avenues of research suggested or enabled by our work.

Higher Order Ambisonics is a spatial audio technique that aims to recreate a sound image over as large a listening area as possible. Only limited investigation has taken place into localisation with Ambisonics and Higher Order Ambisonics at off-centre listening positions. This thesis presents the results of three psychoacoustic localisation experiments Investigating off-centre localisation of first and third order Ambisonics under different conditions: for studio and concert hall sized arrays, and for transient vs ongoing stimuli. A detailed analysis of the results of each experiment is carried out 'to determine the robustness of the tested systems. Comparisons are made between the results of the three experiments to determine the influence of changing the stimulus or increasing the arrival time delay between loudspeakers, where the relative gains of the loudspeakers was found to be perceptually more important than increased time differences between them. The usefulness of these results can be increased by comparison with models for prediction of human localisation, where a robust model would afford fast evaluation of ambisonic systems and allow system optimisation for off-centre positions. Therefore, evaluation Is performed for two binaural models on their ability to predict the results of the psychoacoustic experiments. A model by Dietz and a modified version of the Undemann model are evaluated. Finally, the energy vector model, prevalent in the Ambisonics community, is extended to include elements of the precedence effect. The binaural models, the standard energy vector, and the precedence-extended model are evaluated by comparison to the perceptual results. The robustness of each of the binaural and vector models is discussed in the context of their use as predictors of localisation at off-centre listening positions. The predictions of the precedence~extended energy vector are found to exhibit the lowest deviation from the perceptual results.

Cette thèse examine comment les catégories de marché -ensembles qui partagent des similarités cognitives et culturelles- impactent la performance et l'évaluation des entreprises.Le consensus répandu dans la littérature indique que les organisations qui évoluent dans plus d'une catégorie sont sanctionnées tant au plan économique que social.Remettant en cause ce consensus actuel sur "l'impératif catégorique", cette thèse avance l'idée que les acteurs d'un marché ont un rôle plus complexe que simplement réprimer toute violation des catégories établies. Aussi dans ce contexte, être engagée dans plusieurs catégories de marché pour une organisation à la fois améliore son évaluation sociale mais réduit sa performance en cas de perceptions divergentes de ses affiliations catégorielles. Les données empiriques de cette thèse portent sur les cabinets d'avocats d'affaires dans trois grandes métropoles (New-York, Paris et Londres) au cours d'une décennie (2000-2010). Les cabinets d'avocats multi-services - ceux qui exercent dans plusieurs domaines du droit- obtiennent une meilleure évaluation de la part des clients tant au niveau global du cabinet que pour chacune de leurs spécialités juridiques. Toutefois, les désaccords entre clients en terme d'évaluation portant sur chacune des spécialités juridiques offertes détériorent la performance financière des cabinets. Cette thèse approfondit notre compréhension du rôle que jouent les catégories sur les marchés et les stratégies d'extensions catégorielles que les entreprises mettent en oeuvre. Ce travail contribue également aux études sur le champ juridique et a des implications pour la conduite stratégique des cabinets d'avocats d'affaires
This dissertation explores how market categories - clusters that share cognitive and cultural similarities - impact firms' performance and evaluation. Pervasive consensus in literature indicates organizations that do not fall into a single category suffer economic and social disadvantages.Unsettling this current consensus about the categorical imperative, this dissertation advocates that external audiences have a more complex role than simply patrolling the boundaries and sanctioning any infringement of established categories. They scrutinize categories in various ways depending on their needs. They infer some characteristics of firms from one category membership to another. They diverge about the category memberships and evaluation of firms. This dissertation provides evidence that in such cases, spanning categories both leads to positive social evaluations for organizations, but decreases performance in case of inconsistency across categories. Empirically I study the corporate legal services market in three major financial locations (New-York City, Paris and London) over a decade (2000-2010). My findings are twofold:(i) multi-category law firms- those that are engaged in several practice areas of law - receive better social evaluation from clients both at the firm level and at the practice area level; (ii) disagreement among clients' evaluation about law firms' practice areas undermines their financial performance. This dissertation deepens our understanding of the role that categorical structures play in markets and the category-stretching strategies firms implement to better navigate the "category map". This work contributes also to research in legal studies and has implications for law firms' business development

Annotation:

Evidence from research in psychology and auditor judgment has shown that perceptions that form early in a sequential judgment process can influence subsequent judgments. Auditing Standard 12 requires auditors to identify fraud risk factors and assess the risk of fraud as part of the process of assessing overall misstatement risk. While it is expected that fraud risk assessments should have a bearing on overall risk assessments, it is possible that perceptions formed from assessments of fraud risk can negatively affect the evaluation of any evidence reviewed thereafter. Because different classes of transactions may be affected by fraud risk factors in different ways, fraud risk assessments may differ across classes of transactions. These differences may make subsequent auditor judgments susceptible to the contrast effects bias, where subjects overreact to the differences such that the fraud risk assessments influence auditor judgment more than they should. This study examines whether auditors who learn that fraud risk is low for one class of transactions immediately after examining a class of transactions that has high fraud risk, can overreact to the contrast such that they reduce their sensitivity to evidence that suggests increased misstatement risk. The study also examines whether these contrast effects can be mitigated by acquiring information about fraud risk assessments later in the sequence of evidence, after auditors have reviewed and assimilated evidence related to other risks. The study finds that, as predicted, auditor judgments are influenced by contrast effects. Auditors who examined classes of accounts for which fraud risk assessments were different were less sensitive to evidence suggesting increased risk in accounts that had been identified as having low fraud risk. However, contrary to predictions, these contrast effects were not mitigated by evidence order.

The first order ternary interaction parameters of bismuth in molten copper containing either iron, arsenic or antimony have been evaluated using a pseudo equilibrium process at temperatures between 1398 K and 1473 K. The isopiestic distribution technique developed in this investigation yielded the following results: εFeBi=[(1.11x10⁶)/T]- 754 εAsBi=[(4.4x10⁴)/T]-24 εSbBi=-11 These results, coupled with other activity data, have been used to calculate the isoactivity curves for each constituent in the copper rich corner of each ternary system. The basis for the ternary interactions associated with εFeBi, εAsBi and εSbBi are also discussed.

Annotation:

This thesis attempts to integrate the three supplier processes- supplier segmentation, supplier selection/evaluation and order allocation- based on a case study of a white goods manufacturer. These processes are dealt with in a hierarchical manner, where the decisions at an earlier stage (supplier segmentation) may affect on the results of later stages (supplier selection/evaluation and order allocation). Based on a wide set of variables gathered from the supplier segmentation literature and from the framework developed by the case company, a factor analysis is performed. The resulting eight factors (complexity and criticality, supply market dynamism, supplier&rsquo
s economic dependence, buyer&rsquo
s supplier dependence, uncertainty, supplier capabilities, supplier&rsquo
s specialization to white goods manufacturer and possibility of harm to user) are used for clustering analysis with the K-means method. Three different clustering schemes (4-clusters, 8-clusters, and 18-clusters) are analyzed to see the effect of number of clusters on the cluster means. A supplier selection model is constructed by the PROMETHEE method as was done in a former study at the same company. Two different scenarios are considered in the supplier selection phase: First, data from the former study are kept as they are. The second scenario considers a change of criteria weights. As a result, the qualified suppliers were found to be the same in both scenarios, but the rankings and net flows, which were inputs to the order allocation model, changed. The effects of these changes were discussed at a conceptual level, due to a lack of case data for the order allocation model.

Annotation:

Hollow fills are composed of excess spoil and debris produced from surface coal mining that is not returned to the original mined site. Hollow fills are often constructed in the head of hollows nearby or adjacent to the mined land area, which may be the origins of headwater streams or drain into low order systems. Eleven hollow fills were utilized in evaluating the influence fill drainages had on low order streams in Virginia and West Virginia. The study was conducted in six watersheds including; Five Mile Creek in Mingo County, West Virginia, Trace Fork in Mingo County, West Virginia, Lavender Fork in Boone County, West Virginia, Middle Creek in Tazewell County, Virginia, South Fork of the Pound River in Wise County, Virginia, and Powell River in Wise County, Virginia. Bioassessment procedures used in the evaluation of hollow fill drainages included water/sediment chemistry, acute water column toxicity testing using Ceriodaphnia dubia, chronic sediment toxicity testing using Daphnia magna, benthic macroinvertebrate surveys, and in situ Asian clam (Corbicula fluminea) toxicity testing. Common significant differences in water quality between reference and fill influenced sites, among all watersheds, were elevated conductivity and water column metal concentrations, particularly aluminum and copper. Water column and sediment toxicity testing reported limited significant mortality or reproductive impairment associated with hollow fill drainages. The West Virginia watersheds used in the study consisted of headwater streams originating directly from the settling ponds, placed at the base of the hollow fills, receiving drainages from the fills. Benthic macroinvertebrate analysis reported no significant alteration in total taxa or EPT richness downstream of the ponds. Yet, collector filterer populations, including benthic macroinvertebrates and in situ Asian clams, were enhanced directly downstream of the ponds due to organic enrichment originating from the ponds. A decrease in collector filterer populations and lowered clam growth suggested the organic enrichment dissipated downstream from the ponds. Chlorophyll a analysis of the phytoplankton community was not significantly related to the enhance collector filterer populations in the streams, however the high concentrations in the settling ponds suggest abundant algal communities. The hollow fills evaluated in Virginia drained into receiving systems, whose headwater origins were not directly related to hollow fill drainages. Low taxa richness was associated with the hollow fill and settling pond drainages, however receiving system sites were minimally influenced. Yet, as reported in the West Virginia watersheds, the settling ponds input organic enrichment that enhanced collector filterer populations, including benthic macroinvertebrates and in situ test clams. An analysis of the hollow fillsâ age, or maturity, reported no significant difference between young and old fills. In general, a common feature of among the various aged fill drainages was elevated conductivity, compared to reference sites of the watersheds.

The task of this thesis is to analyse the wear factors in a diesel engine fuel system. Tests based on common documented wear factors and theory will be used in order to develop and localize the wear enhancing inputs during usage. The test rig used in the thesis is a 6-cylinder 13-liter Scania diesel engine, powered with an electrical engine in a non-firing test application. The non-firing procedure is done in order to isolate the damage produced from the fuel circulation in the fuel system. The main parameters to control in this test is engine speed , fuel temperature, rail pressure and injection rate. The wear factors analysed and aggravated during the tests was abrasion in the bearings and cavitation damage in the valves of the high pressure pump. The aggravation of the bearing abrasion was done by decreasing the engine speed and limit the supplied oil pressure by closing the inlet and outlet for the pump. The aggravation of the cavitation damage was done by maximising all the input parameters. Further understanding of the connection to cavitation damage growth and the input parameters where gathered by altering one parameter at a time. There where no indication of damage due to bearing abrasion, even after several alterations. Cavitation damage could be accelerated by decreasing the vapour pressure, and/or increase the flow speed of the fluid. Unfortunately an increase in fluid velocity created an uneven damage generation in the high pressure pump and should not be used as main parameter to accelerate the wear. An increased damage growth due to a decrease in the vapour pressure should be further investigated. Additional test time will be a necessity for a greater comprehension and a more even damage generation.

Annotation:

In the present work reduced order models (ROM) that are independent from the full order finite element models (FOM) considering geometrical non linearities are developed and applied to the dynamic study of rotating structures. The structure is considered to present nonlinear vibrations around the pre-stressed equilibrium induced by rotation enhancing the classical linearised approach. The reduced nonlinear forces are represented by a polynomial expansion obtained by the Stiffness. Evaluation Procedure (STEP) and then corrected by means of an original procedure by means of a Proper Orthogonal Decomposition (POD) that filters the full order nonlinear forces before projection. The latter model is named STEP with Correction (StepC). Different types of reduced basis are presented and tested. Some of these bases are parametrised with respect to the rotating velocity reducing considerably the construction of the ROM. The results obtained with the StepC ROM are in good agreement with the solutions of the FOM and are capable of reproducing the coupled motion of the structure. Furthermore they are more accurate than the classsical Linearised ROM solutions and than the STEP ROM without correction. The proposed StepC ROM provides the best compromise between accuracy and time consumption of the ROM
Dans le présent travail, des modèles d’ordre réduits (ROM) indépendant des modèles ́eléments finis d’haute fidélité (FOM) ont ́eté d ́eveloppés pour l’etude de la dynamique non linéaire des structures en rotation. Les vibrations de la structure autour de l’équilibre précontraint induit par la rotation sont considérées comme non linéaires, améliorant l’approche linéarisée classique. Les forces généralisées non linéaires sont approximées par un polynôme d’ordre trois obtenu avec la procédure Stiffness Evaluation Procedure (STEP). Ici, une approche originale est proposée pour corriger les forces non linéaires à l’aide d’une base de forces non linéaires obtenue avec une décomposition orthogonale aux valeurs propres (POD). Ce modèle est nommé STEP avec Correction (StepC). Différents types de base réduite sont présentés et testés. Certaines de ces bases sont paramétrées en fonction de la vitesse de rotation, ce qui réduit considérablement le temps de construction du modèle réduit. Les résultats obtenus avec le modèle StepC ROM sont en bon accord avec le FOM et sont capables de reproduire le couplage en déplacement entre les dégrés de liberté de la structure. De plus, elles sont plus précises que les solutions ROM linéarisées classiques et que le modèle STEP ROM sans correction. Le modèle StepC ROM proposé offre le meilleur compromis entre précision et temps de construction du ROM

Obesity in children is a nationwide problem. Physical activity is one way to help children stay fit and prevent obesity. Unfortunately, access to technology involving sedentary behavior is easier than ever. Fortunately, for this generation of students there is a way to combine physical activity and technology through exergaming. In order to encourage students to participate in exergaming, the students should be able to play games they prefer. The purpose of this study was to apply a paired choice preference assessment, rank order card sort, and social validity surveys to determine the preference order of six exergames for six elementary students and measure heart rates as the children played the six exergames. The results of this study show that children had different preferences as evident by the rank order card sort, social validity survey, and paired choice preference assessment. The pre-rank order card sort was significantly correlated with the paired choice assessment. On the other hand, the pre-social validity survey was not significantly correlated with the paired choice assessment.

ENGLISH ABSTRACT: The aim of this paper was to prove the contribution of the Works Order Close-Out Meeting process at Nampak Flexible Ndabeni, through the development of a Close-Out Meeting contribution evaluation model. Although the value of the Close-Out Meeting process is intuitively understood, a formal measurement would underscore the importance of the process. Using a funnel-based analysis, a total of 63 Close-Out Meeting findings was identified for formal benefit review and were categorised into five finding groups. For each of these five groups a contribution measurement methodology was developed. The methodology was rooted in sound management and ERP theory and then applied to the findings in each group. The following key groups were identified and discussed: Incorrect standards. The importance of correct standards was shown, and the potential misstatement due to incorrect standards was quantified. The analysis showed that effective, ongoing variance review can identify errors in standards and that changes can be initiated and authorised in a short timeframe. ERP process review. Findings that specifically addressed lack of proper process were reviewed and real benefit was calculated for three categories, namely information misstatement, risk mitigation and productivity gains. Formulas were developed and applied for the benefit calculation. The analysis showed it is dangerous to assume that processes are cast in stone or fundamentally sound, and that the Close-Out review process not only identifies deficiency of these processes, but initiates corrective action. Shop floor process review. The investigation into findings that addressed process conformance showed that in most cases the process breakdowns related to the accuracy of information captured into the ERP. The impact of poor information, process non-conformance and corrective action was clearly shown. Actions to improve performance. Targeted actions to improve production performance were subdivided into actions that improved productivity and actions that reduced the risk of recurrence of a negative event. Benefits were calculated using established methods, and in both cases the benefit was substantial. Business decision confirmation. The Close-Out Meeting sometimes forced analysis that did not lead to action but to a better understanding of the business reality. What was shown is that the ability to identify, list and analyse findings of this nature added value. By expanding the benefit analysis beyond a simplistic implementation of corrective action, the scope of benefits was increased. The study achieved several objectives. The analysis showed that corrective actions taken by management have a scientific base and that the implementation of corrective actions delivered real business value. This allowed the business to place the Close-Out Meetings in the correct context, as the business could conclude that Close-Out Meetings were fundamental to its continued success. From a theoretical point of view the body of knowledge around Close-Out Meetings was expanded, while the results also supported the Nampak ERP value case. Close-Out Meetings at Nampak Flexible delivered clear, measurable benefits when discussion points were converted to actions that were acted upon by the business. The value was of such a nature to confirm the importance of Close-Out Meetings as a component of good ERP-manufacturing practice.
AFRIKAANSE OPSOMMING: Die doel van hierdie werkstuk was om die bydrae van die "Works Order Close-Out Meeting" proses by Nampak Flexible Ndabeni te bewys met behulp van 'n "Close-Out Meeting" evaluasiemodel. Alhoewel die waarde van die "Close-Out Meeting"-proses intuitief aanvaar word, aksentueer die ontwikkeling van 'n formele maatstaf die belangrikheid van die proses. 'n Evaluasieproses het 'n totaa1 van 63 bevindinge opgelewer vir analise. Die bevindinge is ingedeel in vyf groeperings en vir elke groepering is 'n ste1 maatstawwe ontwikkel ten einde die bydrae van die bevindinge te meet. Hierdie maatstawwe was gebaseer op bestaande, aanvaarde ERP- en bestuursteorie. Die volgende vyf groepe was geidentifiseer en bespreek. Foutiewe standaarde. Die belangrikheid van akkurate standaarde in die stelsel is bewys, en die skaal van informasiefoute as gevolg van verkeerde standaarde is gekwantifiseer. Daar is bewys dat effektiewe, voortdurende variasie-analise foute kan identifiseer en dat die nodige korrektiewe aksie vinnig implementeerbaar is. ERP-proses. Bevindinge wat voortspruit uit swak prosesse is geidentifiseer en die waarde van die korrektiewe aksie is op drie vlakke geanaliseer, naamlik informasiefoute, risikobeheer en produktiwiteitsverbetering. Formules is ontwikkel en toegepas om die waarde van die korrektiewe aksie te bepaal. Daar is bewys dat dit gevaarlik is om aan te neem dat besigheidsprosesse fundamenteel korrek is, en dat die "Close-Out Review"-proses nie net foutiewe prosesse uitgewys het nie, maar ook die nodige korrektiewe aksie gedryf het. Fabrieksvloerproses. Die ondersoek na bevindinge wat prosesafwykings uitgewys het, het aangedui dat afwykings meestal voorgekom het as gevolg van foutiewe informasie in die ERP-stelsel. Die impak van foutiewe informasie, prosesafwykings en inisiatiewe om die akkuraatheid van informasie te verbeter is duidelik gewys. Produksieverbetering. Bevindinge wat gelei het tot inisiatiewe om produksie te verbeter is verdeel tussen produktiwiteitsverbetering en risikobeheer. Die waarde van die inisiatiewe is bereken met die gebruik van ontwikkelde metodes en in beide gevalle was die resultate baie positief. Ondersteuning by besluitneming. Die "Close-Out Meeting"-proses het somtyds gely tot analise wat nie aanieiding gegee het tot korrektiewe aksie nie, maar wel daartoe gelei het dat bestuur se begrip van besigheidsrealiteit verbeter het. Daar is bewys dat 'n proses wat besigheidsinformasie aan bestuur kan weergee ter ondersteuning van bestuursbesluite, waardevol is. Die mate van voordeel wat uit die proses stem is vergroot deur die waarde-analise uit te brei sodat dit meer is as die blote analise van korrektiewe aksie. Die berekende voordeel uit die "Close-Out Meeting"-proses is groter wanneer die hestek van die voordeel vergroot word om meer as net die direkte waarde van korrektiewe aksie in te sluit. Die studie het voldoen aan verskeie doelwitte. Daar is bewys dat bestuursaksie 'n wetenskaplike basis het en die uitvoer van hierdie aksies besigheidswaarde toevoeg. As gevolg hiervan kon die besigheid "Close-Out Meetings" in die regte konteks plaas en tot die slotsom kom dat hierdie proses 'n fundamentele drywer van besigheidsukses is. Ten slotte is die teorie oor "Close-Out Meetings" uitgebrei en die resultate het ook die waarde onderskryf wat Nampak uit sy ERP-implementasie gekry het. "Close-Out Meetings" by Nampak Flexible het duidelike meetbare voordele opgelewer wanneer die probleme wat geidentifiseer is gelei het tot korrektiewe aksie. Die waarde was van so 'n aard dat die belangrikheid van "Close-Out Meetings" as 'n komponent van goeie vervaardigingsbestuur in 'n ERP-konteks duidelik bewys is.

Annotation:

This thesis reviews algorithms that have been developed for classifying lidar data and identifies a progressive morphological filter for evaluation and improvement. Two potential weaknesses evaluated include the row-column order bias and grid orientation bias. Four different row-column orderings were developed to test for bias associated with the order choice. Moreover, a method rotating the filter grid to a series of angles was developed for testing bias associated with grid orientation. Measures of success of the improvements include Type I and II errors, where results are compared with a hand-produced "truth" dataset. Two datasets, one urban, the other rural, were selected for testing the modified filters. The results are presented and discussed for each algorithm. It was found that the four row-column orders all classified the dataset exactly the same. After the erosion and dilation functions were completed, the same surface profiles and elevations were produced regardless of row-column ordering. The filter windows used by the algorithm were found to create a rectangular area where the minimum and maximum values within that area were always selected. Therefore, it was found that the row-column orders did not create a bias in the classification. However, grid orientation was found to greatly affect results. Misclassification problems occurred at ridgelines, mounds, and along roads with ditches and steep slopes running along them. Grid angles running parallel to these objects were found to avoid these errors. Buildings also created errors, but were minimized with grid angles crossing them at 45 degrees. The selected angle directions significantly affect the classification results in all cases. Therefore, the grid orientation bias was verified. Two new methods of combining the results from the various angles have been developed. The first method used the best two classifying angles to combine the results. Best results were found in datasets with terrain objects positioned in similar directions for this method. The Multiple Angle method used all of the angle classifications to combine the results. This method performed best on datasets with terrain objects oriented in numerous directions. More accurate terrain models and better overall classification results have been generated using these methods.

Annotation:

Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance. Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0. The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively. Using the formic acid extraction method, the genus and species identification rates were 83% and 44%, respectively. For the longest sample preparation method, liquid media culturing before formic acid extraction, successfully identified all strains except one, which resulted in an identification rate of 94% and 78% respectively. This study shows that preparing samples in cultured liquid media MADLI-TOF MS effectively identified fungal strains to both genus- and species-level. This method was however too time-consuming and cumbersome to be recommended as a replacement to the conventional method. Future studies should be aimed at expanding the reference library and making the direct extraction method more reproducible in terms of obtaining more reliable identification rates.

This thesis .investigates the function of a topicalized constituent .in the narrative non-direct speech texts .in 2 Kings. Many traditional BH grammarians described the :function of a topicalized constituent as "emphasis". Recent BH grammarians pointed out that extralinguistic factors like the total communicative context should also be considered in the description of a function for a topicalized constituent. The shift from the structural to a more pragmatic approach is illustrated in this study. The pragmatic approach proved to be not only possible, but also advantageous to the study of function in BH. The aim of this study was to test the viability and results of the various theories and categories of the BH linguists. This study also researched whether their linguistic approaches are indeed an improvement on the descriptions as defined by the traditional grammarians. In other words, to see whether and in which way more recent studies of BH could aid the understanding of the function of a topicalized constituent in BH word order. The methodology utilized in this study is briefly outlined as follows: 1. This study examined the description of word order in terms of the traditional and more recent approaches. The categories used to describe the function of a topicalized constituent were our main focus. At the end we compiled a theoretical frame of reference that we regard as representative of modem attempts to acquire a more refined comprehension of BH word order. A theoretical linguistic framework was formulated which could be used in our description of a sentence in BH in 2 · Kings. This attempt could be described as eclectic because it used the diverse perceptions from the various linguistic approaches. Richter's theoretical linguistic framework (with its limitations) together with contributions of Van der Merwe, Buth and Gross were used as a basis for the description of the sentences. 3. Sentences were analysed systematically and holistically at the different levels of description, namely morphology, morphosyntax, sentence syntax, semantics and pragmatics. Because of the difficulty in defining semantics and with pragmatics still in disarray, this study defined some semantic-pragmatic concepts it worked with. 4. In the description of sentences we incorporated and tested the viability of the different categories of various grammarians. By carefully considering the context of each sentence, this study posed the question: which, if any; of the categories could adequately describe the semantic-pragmatic function of a topicalized constituent in 2 Kings.

In this thesis the Third-Party Logistics (3PL) partnership between the Japanese trading company Gadelius and the European logistics provider Mahé is investigated. This was done as a case study, mainly taking place on location at Gadelius’ headquarter in Tokyo.

The purpose has been to identify and evaluate the fulfilment of initial objectives, both with respect to agreed on terms and expectations of each party, analyze the reasons behind result and provide recommendations for the future.

In terms of what is strictly defined and agreed on in the contract the partnership is principally fulfilled, but this setup is not good in terms of how full 3PL-effects could be achieved.

The not so strictly defined parts of the contract stating that Mahé should work proactively are however not fulfilled to the same degree. This is connected to the lack of a dedicated Mahé representative being integrated into the OtD-team at Gadelius.

Because of this Gadelius’, to begin with very high, expectations on effects have become unrealistic, which has contributed to bad sentiments against Mahé and their capabilities. This has further been enhanced by Key Performance Indicators that don’t fully match the essential objectives with the partnership.

To change the situation two possible ways for the future are presented. If Gadelius’ focus is on indirect cost reductions an expanded partnership should be chosen, while a focus on direct cost reductions and a need for an easier change implementation call for a more limited partnership. For both alternatives new ways for measuring performance are suggested.

The topic of bioenergy, biofuels and bioproducts remains at the top of the current political and research agenda. Identification of the optimum processing routes for biomass, in terms of efficiency, cost, environment and socio-economics is vital as concern grows over the remaining fossil fuel resources, climate change and energy security. It is known that the only renewable way of producing conventional hydrocarbon fuels and organic chemicals is from biomass, but the problem remains of identifying the best product mix and the most efficient way of processing biomass to products. The aim is to move Europe towards a biobased economy and it is widely accepted that biorefineries are key to this development. A methodology was required for the generation and evaluation of biorefinery process chains for converting biomass into one or more valuable products that properly considers performance, cost, environment, socio-economics and other factors that influence the commercial viability of a process. In this thesis a methodology to achieve this objective is described. The completed methodology includes process chain generation, process modelling and subsequent analysis and comparison of results in order to evaluate alternative process routes. A modular structure was chosen to allow greater flexibility and allowing the user to generate a large number of different biorefinery configurations The significance of the approach is that the methodology is defined and is thus rigorous and consistent and may be readily re-examined if circumstances change. There was the requirement for consistency in structure and use, particularly for multiple analyses. It was important that analyses could be quickly and easily carried out to consider, for example, different scales, configurations and product portfolios and so that previous outcomes could be readily reconsidered. The result of the completed methodology is the identification of the most promising biorefinery chains from those considered as part of the European Biosynergy Project.

Partout où la pierre est facilement disponible, on trouve des constructions en maçonnerie de pierre. Suivant les coutumes et les usages, les blocs de pierres sont assemblés bruts, simplement ébauchés ou parfaitement taillés, avec ou sans l'ajout d'un liant. Supplantée par le béton dans les constructions neuves depuis le milieu du XX} siècle, les ouvrages en maçonnerie demeurent majoritaires dans le patrimoine bâti français, un patrimoine qu'il convient d'entretenir rationnellement. L'objectif de ce travail de thèse est de poursuivre l'élaboration d'un cadre scientifique rigoureux et opérationnel afin de donner aux décideurs et aux gestionnaires les outils nécessaires pour mener à bien leur mission. Nous proposons ici deux outils d'évaluation de la stabilité d'ouvrages de soutènement en maçonnerie basés sur l'utilisation conjointe du calcul à la rupture avec des méthodes d'homogénéisation. Dans un premier temps, nous mettons d'abord au point un outil analytique permettant de dimensionner des ouvrages neufs ou d'évaluer la stabilité d'ouvrages peu déformés. Cet outil permet également de dimensionner des solutions de renforcement par clouage lorsque cela est jugé nécessaire. Dans un deuxième temps, nous implémentons cet outil dans un code numérique afin de lui donner la souplesse nécessaire à l'étude d'ouvrages non-conventionnels, de grandes taille ou fortement pathologique. Enfin, nous mettons en oeuvre plusieurs campagnes expérimentales qui nous fournissent les données nécessaires à la validation de ces modèles de calcul
Wherever stone is readily available, we encounter stone masonry buildings. Depending on customs or dedicated use, the blocks are used raw, lightly faced or perfectly cut, with or without the use of mortar. Althougth concrete has replaced masonry in new construction for some decades, the better part of the French built heritage is made of masonry, an heritage we are responsible for. This works aims at contributing to create a reliable scientific frame for that purpose. This thesis uses the yield design theory alongside with homogenisation techniques to study the stability of stone masonry earth retaining walls. First, we provide an analytical tool suitable for designing new structures or assessing the stability of existing ones that are still in good shape. Should it be needed, this tools allows for the design of a strengthening solution based on soil-nailing. Then, we implement it in a finite element code to give it the versatility required to study unconventionnal structures or structures badly damaged. We then present several experimental campaigns aiming at validating the proposed tools

Annotation:

This study was conducted to investigate the extent to which teachers could be trained by a school administrator to conduct teaching following High Definition teaching strategies in order to increase the teaching of higher order thinking skills. High Definition teaching was expected to facilitate students' acquisition of higher order thinking skills by teachers explaining, asking questions and using answers along the lines of Bloom's Taxonomy (application, analysis, synthesis and evaluation) while covering text book knowledge, inferential concepts, students' experiences, previous lesson concepts, related subject concepts and test concepts. This study assumed that if the methods were successful, it would indicate that instructional administrators could conduct in-the-teaching process teacher development to improve the teaching of higher order thinking skills, thereby enhancing student performance on standardized tests. In this study, the following variables were measured as the dependent variables: (1) higher order thinking skills (2) lesson planning skills and (3) knowledge about students. The independent variables were the experimental group in comparison to its baseline performance (pretest) and a control group with no treatment. The design chosen for this study was an experimental design that involved both an experimental and a control group in a pretest-posttest data analysis. The control group was defined as the group of 14 teachers who were randomly selected from the faculty and assigned for no treatment. The experimental group was defined as the group of 15 teachers who were randomly selected from the faculty and assigned for treatment. The teachers in the pretest-posttest settings: (1) wrote their views about students as learners (2) had their lesson plans analyzed, (3) had their teaching videotaped for the purpose of comparison with their own pretreatment video, (4) had their teaching videotaped for the purpose of comparison with the control group and (5) wrote their views about students as learners after treatment. An analysis of the videotape data indicates that training of teachers in High Definition planning, teaching and evaluation improved the number and types of higher order interactions occurring in the classroom with respect to some of the dimensions measured. An analysis of lesson plans indicated improvement by some teachers in their understanding of the strategies taught. An analysis of the questionnaire data with respect to each question indicates posttreatment changes in teaching values by the teachers.

Annotation:

Tumour Necrosis Factor-Related Apoptosis Inducing Ligand (TRAIL) is a protein belonging to the TNF family of ligands. TRAIL is able to induce apoptosis in tumour cells, whilst leaving normal cells unaltered, representing therefore an attractive anti-cancer agent. In breast cancer, however, different cell lines are resistant to TRAIL. Moreover, many studies have demonstrated that breast cancer stem cells (bCSCs), the cells that are the most responsible for relapses and metastasis development, are resistant to TRAIL. Cellular FLICE-Like Inhibitory Protein (c-FLIP) plays a crucial role in TRAIL-resistance due to its ability to interfere with the TRAIL pathway, preventing therefore the apoptosis. In the course of a previous study, the homology model of c-FLIP has been constructed and using a structure-based virtual screening of commercially available compounds, one hit compound (3) able to inhibit c-FLIP at micromolar concentrations has been identified. Starting from the structure of the hit compound, several new derivatives belonging to four different structural families were designed and synthesised: sulfonamide derivatives, amine derivatives, amide derivatives and methylene derivatives. All the newly synthesised compounds were tested in an in vitro assay for their ability to sensitise TRAIL-resistant MCF-7 breast cancer cell line to TRAIL. Different derivatives retained the ability to increase TRAIL sensitisation showing a similar or slightly improved activity compared to the original hit. Some of the most promising compounds were further evaluated in in vitro pharmacokinetic assays, dose-response and cytotoxicity studies. The results obtained from these studies suggested the identification of a novel hit compound (88) which showed the ability to increase TRAIL sensitisation with an IC50 value in the range of 15-19 μM and improved metabolic stability compared to 3. Additionally, molecular docking analyses suggested a potential ability of the newly synthesised derivatives to occupy the pocket of c-FLIP. Taking into consideration all these results, a series of novel potential small molecule c-FLIP inhibitors showing ability to increase TRAIL sensitisation in resistant breast cancer cells and breast cancer stem cells was developed.
