Abstract:
In this paper, a nominal sensor placement methodology for leak location in water distribution networks is presented. To reduce the size and the complexity of the optimization problem a clustering technique is combined with the nominal sensor placement methodology. Some of the pressure sensor placement methods for leak detection and location in water distribution networks are based on the pressure sensitivity matrix analysis. This matrix depends on the network demands, which are nondeterministic, and the leak magnitudes, that are unknown. The robustness of the nominal sensor placement methodology is investigated against the fault sensitivity matrix uncertainty. Providing upon the dependency of the leak location procedure on the network operating point, the nominal sensor placement problem is then reformulated as a multi-objective optimization for which Pareto optimal solutions are generated. The robustness study as well as the resulting robust sensor placement methodology are illustrated by means of a small academic network as well as a district metered area in the Barcelona water distribution network.

To reach this objective a series of measurements was done in the hydraulic pump rotors, the used calculation methodology was based on the hydraulic pump theory and on experimental coefficients, which were supplied by the available specialized literature. The obtained results allowed to verify that a simple, fast, low cost method can supply either the nominal or project values of the evaluated pump models. This work concluded that the proposed methodology was capable of estimating the nominal values of the outflow Q0, the manometric height H0, the potency P0, the Net Positive Suction Head required NPSHr0, the output Rg0 and the specific speed Nq0 starting from measurements of the physical characteristics of the rotors of the studied pump models.

Summary In this paper, we present the methodology for the construction of electronic dictionaries for frozen nominal sequences in Korean and their inflectional forms. For efficiency, we propose two independent dictionaries : one for frozen nominal sequences using list or graphical representation and the other for nominal postpositions using graphical representation. One could merge the two dictionaries into a single dictionary through the aid of the pre-defined inflectional code of each frozen nominal sequence and the inflection module in INTEX. In spite of the substantial differences between inflectional and agglutinative languages, we can describe frozen nominal sequences in Korean and their inflectional forms in INTEX.

Abstract:
Purpose Automatic interpretation of Nominal Compounds is a crucial issue for many applications, for example, sentence understanding, machine translation, question-answering system and so forth. Many automatic interpretation models of Nominal Compounds use the strategies based on verbs or rules to obtain the interpretation of compounds. However, the performances of these models are still limited. The purpose of this paper is to propose an effective approach for automatic interpretation of Chinese nominal compounds. Design/methodology/approach The authors propose a top-down and bottom-up model based on rules and large-scale corpus for automatic interpretation of Nominal Compounds. Findings Experimental results demonstrate that the proposed model outperforms the state-of-the-art automatic interpretation model. Originality/value The paper is an up-to-date study of automatic interpretation for Nominal Compounds. It can help people understand the meaning of Nominal Compounds in reading. With a better understanding of Nominal Compounds, we can discover more hidden knowledge in them.

Abstract:
Purpose Conformal cooling channels in additively manufactured molds are superior over conventional channels in terms of cooling control, part warpage and lead time. The heat transfer ability of cooling channels is determined by their geometry and surface roughness. Laser powder bed fusion manufactured channels have an inherent process-induced dross formation that may significantly alter the actual shape of nominal channels. Therefore, it is crucial to be able to predict the expected surface roughness and changes in the geometry of metal additively manufactured conformal cooling channels. The purpose of this paper is to present a new methodology for predicting the realistic design of laser powder bed fusion channels. Design/methodology/approach This study proposes a methodology for making nominal channel design more realistic by the implementation of roughness prediction models. The models are used for altering the nominal shape of a channel to its predicted shape by point cloud analysis and manipulation. Findings A straight channel is investigated as a simple case study and validated against X-ray computed tomography measurements. The modified channel geometry is reconstructed and meshed, resulting in a predicted, more realistic version of the nominal geometry. The methodology is successfully tested on a torus shape and a simple conformal cooling channel design. Finally, the methodology is validated through a cooling test experiment and comparison with simulations. Practical implications Accurate prediction of channel surface roughness and geometry would lead toward more accurate modeling of cooling performance. Originality/value A robust start to finish method for realistic geometrical prediction of metal additive manufacturing cooling channels has yet to be proposed. The current study seeks to fill the gap.

Abstract:
Drainage plants consume more than 30% of the electricity consumed by all of the mine's electromechanical equipment. Therefore, mine drainage installations must have high energy efficiency and reliability. An analysis of the operation of the existing drainage installations shows that the pumps are selected with an overpressure. As a result, cavitation occurs in the pumps. It is established that 60-70% of the drainage plants operate in cavitation modes and have a reduced efficiency and correspondingly higher electricity consumption. Known methods for calculating mine drainage installations have the disadvantages, first of all, that they allow the pump to operate in the working area much higher than the rated regime. Pump operation at higher than the nominal supply significantly impairs its energy and cavitation characteristics. An improved method of calculating mine drainage facilities is proposed, through the introduction of additional dependencies and provisions that will increase the energy efficiency of the equipment. The article presents theoretical studies of local resistance of the pipeline of drainage installations. As a result of the research, analytical dependences of the local resistance of the mesh suction valve and the check valve on the diameter of the pipeline were obtained. On the basis of these dependencies an equation is obtained that relates the nominal parameters of the pump and the geometric height of water rise from the inner diameter of the pipeline. This equation is recommended to be used in the calculation of mine district water drainage installations to improve their energy efficiency at the design stage.

Abstract:
This thesis examines the views of A.C.T. primary school teachers about their work to build a picture of the culture of primary school teacher work of primary schools in the Australian Capital Territory. I define teaching culture to mean the behaviour, work practices, beliefs and possible habits teachers display in their efforts to perform the task of teaching. This description of teaching is possibly similar to what some authors describe as the 'sociology' of teaching (e.g. Barton and Walker, 1981). It is also a reflection of Deal's suggestion that culture describes 'the way things are done around here1 (Deal, 1985:605). In this case the study builds a picture of primary school teacher perceptions of the way things are, the culture of primary school teacher work, in the A.C.T. primary teaching system. The study has been designed to identify key workplace issues which preoccupy A.C.T. primary school teachers now and what they perceive to be the significant issues of the future, that is by the year 2005. The Delphi methodology was chosen to be the means to gather and refine information and perceptions from teachers its ability to clarify and refine issues and because the Delphi has amongst its advantages anonymity for participants and the use of experts in the data gathering. The study found that a high proportion of teachers feel stressed about attending meetings, yet wanting at the same time a say in the running of their school. Other results were that teachers considered they are poorly supported by the wider community and that a significant reward of the job was the interaction with the children. Teachers also believe that instructional methods will be radically different by 2005. The study aims to provide current information about the culture of primary school teacher work to teachers themselves and to present to interested authorities and institutions, such as the Department of Education and Training and The University of Canberra or the Australian Catholic University, recommendations for further research and practice to assist in policy design regarding the work teachers do. Some recommendations to the Department of Education and Training include: · the culture of primary school teacher work should be actively promoted to inform the community of the complexity of teacher work and to attract quality applicants to the profession; · that classroom teachers are resourced, at comparable levels to Public Servants or Departmental officers, with equipment such as computers and furniture; · that consideration be given to providing more inservice opportunities for teachers to pursue during stand-down (school holiday) time. Recommendations made to teacher-training institutions include: · regular research and reviews of teacher-training programs, with particular emphasis placed on beginning teacher needs and competencies and to highlighting areas newly recruited and experienced teachers consider require more training; · the design of comprehensive upgrading programs catering for the needs of newly appointed and experienced teachers.

Abstract:
Hamad Medical Corporation, the main healthcare provider in the state of Qatar, sponsored this study to investigate the use of electronic records management as the basis for a novel information management system in its Nursing Department. To assess the viability of an electronic records management system a questionnaire survey of a representative sample of the staff and interviews with key post holders were under taken. Results obtained indicated a wide spread dissatisfaction with the existing manual system. However, introduction of any computer-based technology requires great care. To assist with identifying any issues with this technological change, Soft System Methodology (SSM) was employed to discern what changes could be made to improve the current problematic situation found in the Nursing Department. In fact the change archetypes uncovered (procedural, attitudinal, structural and cultural) formed an innovative input into obtaining a roadmap for development of the electronic staff records system. This roadmap was facilitated by the use of Nominal Group Technique (NGT) and Interpretive Structural Modelling (ISM): In fact the roadmap was an ISM intent structure. The roadmap suggested that change could be affected by having written policy documents and the top goal to be achieved reflected an improvement in manpower placing and budgetary forecasts. The use of a multi-methods approach meant that as well as this study's main objectives being reached, the process encompassed some methodological innovations. This study is the first to use the output of SSM to facilitate the NGT and ISM interactions. Equally, it is the first study of its sort to be applied to the Nursing Department at HMC, Qatar, which is an example of a cross-cultural eastern philosophical tradition. The methods used here revealed some significant findings, and have helped in the development of an electronic records management system for use at HMC, Qatar.

Abstract:
Le but de cette thèse est de proposer une nouvelle classe de GLMs pour une variable réponse catégorielle structurée hiérarchiquement, comme une variable partiellement ordonnée par exemple. Une première étape a été de mettre en évidence les différences et les point communs entre les GLMs pour variables réponses nominale et ordinale. Sur cette base nous avons introduit une nouvelle spécification des GLMs pour variable réponse catégorielle, qu'elle soit ordinale ou nominale, basée sur trois composantes : le ratio de probabilitées r, la fonction de répartition F et la matrice de design Z. Ce cadre de travail nous a permis de définir une nouvelle famille de modèles pour données nominales, comparable aux familles de modèles cumulatifs, séquentiels et adjacents pour données ordinales. Puis nous avons défini la classe des modèles linéaires généralisés partitionnés conditionnels (PCGLMs) en utilisant des arbres orientés et la specification (r,F,Z). Dans notre contexte biologique, les données sont des séquences multivariées composées d'une variable réponse catégorielle (le type de production axillaire) et de variables explicatives (longueur de l'entre-noeud par exemple). Dans les combinaisons semi-markoviennes de modèles linéaires généralisés partitionnés conditionnés (SMS-PCGLM) estimées sur la base de ces séquences, la semi-chaîne de Markov sous-jacente représente la succession et les longueurs des zones de ramification, tandis que les PCGLMs représentent, l'influence des variables explicatives de croissance sur les productions axillaires dans chaque zone de ramification. En utilisant ces modèles statistiques intégratifs, nous avons montré que la croissance de la pousse influençait des événements de ramification particuliers.

Full text
Abstract:
This book sheds light on language variation and change from a generative syntactic perspective, based on a case study of relative clauses in Portuguese and other languages. Concretely, it offers a comparative account of three linguistic phenomena documented in the synchrony and diachrony of Portuguese: remnant-internal relativization, extraposition of restrictive relatives, and appositive relativization. The research methodology adopted involves comparative syntax, both in the diachronic and the synchronic dimensions: Contemporary European Portuguese is systematically compared with earlier stages of Portuguese; moreover, Portuguese is compared with other languages, in particular Latin, English, Dutch, and Italian. The book provides new perspectives on the syntax of relativization. From a theoretical perspective, it shows that competing analyses need not be either false or true universally, but can be instrumental in explaining language variation (both diachronically and synchronically). As for the variation found in the synchronic and diachronic dimensions, it is proposed that languages (and different stages of the same language) might vary according to whether they allow relativization to be derived from specifying coordination. Moreover, the book reports a series of changes that took place in the history of Portuguese after the sixteenth century, which reduced the patterns of nominal discontinuity available in the language.

Abstract:
Supplier selection is a common practice in industrial sector and is usually conducted by engineers and administrators. However, in the healthcare sector, supplier selection is less commonly studied. This chapter proposes a methodology that simplifies the selection of suppliers in hospitals. As case study, the authors propose an example in which they evaluate six potential suppliers as alternatives with five attributes. The proposed methodology integrates the nominal group technique (NGT) to weight the attributes and dimensional analysis to estimate an index of similarity to an ideal supplier. This index of similarity is obtained from the best nominal values of the attributes. This methodology can be easily applied; it is intuitive and friendly to inexpert users, since the evaluation can be performed using a traditional spreadsheet. Also, the proposal allows for the simultaneous evaluation of multiple attributes and can be used by hospital administrators themselves, which prevents hospitals from hiring external services.

Abstract:
A general methodology for intelligent system monitoring is proposed in this chapter. The methodology combines degradation hybrid automata to system degradation tracking and a nonlinear adaptive model for model-based diagnosis and prognosis purposes. The principal idea behind this approach is monitoring the plant for any off-nominal system behavior due a wear or degradation. The system degradation is divided in subspaces, from fully functional, nominal, or faultless mode to no functionality mode, failure. The degradation hybrid automata, uses a nonlinear adaptive model for continuous flow dynamics and a system condition guard to transition between modes. Error Filtering On- line Learning (EFOL) scheme is introduced to design a parametric model and adaptive low in such a way that the unknown part of the adaptive model function is on-line approximated; the on-line approximation is via a Radial Basis Function Neural Network (RBFNN). To validate the proposed methodology, a complete conveyor belt simulator, based on a real system, is designed on Simulink; the degradation is characterized using the Paris-Erdogan crack growth function. Once the simulator is designed the measured current, i’s, and velocity of the IM, ?m, are used to modeling the simplified adaptive IM model. EFOL scheme is used to on-line approximate the unknown TL function. The simplified adaptive model estimates the IM velocity, , as output. and the measured IM velocity ?m are compared to detect any deviation from the nominal system behavior. When the degradation automata detect a system condition change the adaptive model on-line approximate the new TL.

Abstract:
Enterprise Resource Planning (ERP) system is an integrated software system reflecting the business processes of an enterprise. Enterprise Resource Planning (ERP) system is a generic term for integrated systems for corporate computing that supersedes concepts such as Materials Requirements Planning (MRP) of the 1970s and, later, Manufacturing Resource Planning (MRP II) of the 1980s. The objective of customization in ERP implementation is to achieve a fit between the ERP system and the business process that the system supports. Literature review reveals that the customization is the major annoyance in most of the ERP projects. A solution is proposed using a process framework that incorporates participatory learning and decision-making processes based on Nominal Group Technique (NGT) and the evaluation methodology adopting the Analytical Hierarchy Process (AHP). A case study is presented to illustrate its applicability in practice. The upshot of the study is the identification of various customization possibilities for ERP implementation. This study is meant to help managers think about the various feasible customization options available to them. Future research work that can be done in ERP software customization is also indicated.

This research discusses, explains, and interprets the determinants behind the psychosocial aspects of cybercrime victimization and combines the factors incorporated with the causes, patterns, and nature of psychosocial dilemmas in the Pakistani context. Qualitative research methodology by using purposive sampling is adopted, and five case studies are taken. This research is explanatory in its very nature. Unfortunately, Pakistan possesses an ideal environment for the growth of cybercrime. Women register 70% of the cybercrime cases, and more than 60% of crimes are Facebook related. Government officials were involved in leaking the private information of the victims. Most cases are filed against family members, and such cases get dropped even before a trial, as male members of the family represent females. Patriarchy reigns in its real sense as women comparatively have nominal opportunities in Pakistan.

Full text
Abstract:
This chapter presents a statistical methodology for structural damage diagnosis (detection, localization and estimation), in the context of continuous online monitoring. There are several sources of uncertainty such as physical variability, measurement uncertainty and model errors that affect structural damage diagnosis, and therefore, it may not be possible to precisely detect, localize, and estimate damage. Hence, a statistical approach can help to identify these sources of uncertainty, quantify their combined effect on diagnosis, and thereby, provide an estimate of the confidence in the results of diagnosis. Damage detection is based on residuals between nominal and damaged system-level responses, using statistical hypothesis testing whose uncertainty can be captured easily. Localization is based on the comparison of damage signatures derived from the system model. Both classical statistics-based methods and Bayesian statistics-based methods are investigated to quantify the uncertainty in all the three steps of diagnosis, i.e. detection, localization, and quantification. While classical statistics-based methods use the concept of least squares-based optimization, Bayesian methods make use of likelihood function and Bayes theorem. The uncertainties in damage detection, isolation and quantification are combined to quantify the overall uncertainty in diagnosis. The proposed methods are illustrated using the example of a structural frame.

Abstract:
This paper attempts to provide an understanding of some of the issues involved in creating a physical scale model of an assembly using (primarily) rapid prototyping (RP) technology and to develop a semi-formal methodology of interest to scale model builders that guides the process. The methodology starts with either the full scale assembly or the CAD files and all assembly liaison diagrams which are then transformed into the scaled versions assuming use of a nominal scale factor. In the process a “scaling structure table” is created that documents the transformation and it only needs to focus on scaling issues, vs. angular dimensions and other geometric constraints which are invariant with respect to scale. The case study assembly used in this effort is a previously designed hand-powered breadfruit shredder of modest complexity. For various reasons, the process was not as simple as applying the nominal scale factor to all relevant dimensions. The transformation process included strategically adding special scaling features such as ribs, wall thickening, and fillets to ensure adequate strength, and merging of a subassembly into a single part. The final step was to create the physical scale model using mostly plastic-based RP.

Abstract:
Abstract Customers in Ecuador inject the byproduct formation water from production wells into injector wells. A limited injection rate bottlenecks production, which is economically undesirable. Two major contributors limit injection capacity: reservoir injectivity and flowline pressure losses. In the latter case, paraffins, asphaltenes, and scale, collectively referred to as "schmoo," progressively build in the flowline and reduce the internal diameter, limiting flow rate capacity. One cost-effective method to remediate flowlines with significant deposits is coiled tubing (CT) cleanouts. This unconventional method, which calls for optimized planning, execution, and performance evaluation, has been implemented in five flowlines. An economic analysis shows that remediating flowlines using CT cleanout yields significant savings as compared with replacement. After a candidate is identified, job planning takes into consideration flowline length and deviation (to identify maximum reach of CT), schmoo analysis (to design an optimal bottomhole assembly and fluid treatment), and execution logistics (to ensure a viable, reliable, and safe operation). After the cleanout, the flowline is put back into service, and the effectiveness of the treatment is estimated based on system flow rates and pressure losses. The equivalent internal diameter (ID) for the flowlines was improved by over 49% in each of the remediated flowlines, achieving an effectiveness of over 89% of nominal ID and increasing flow rates without a detrimental effect on system pressure. The cleanouts re-established nominal capacity in over 50k ft of flowline that no longer needed replacement. Lessons learned include the ability to complete the cleanout with water alone. The chemical analysis in planning stages showed the absence of carbonates, which enabled a mechanical cleanout with a high-pressure nozzle. Nonetheless, a chemical treatment was designed as a contingency. Another learning was that whereas tubing force models helped predict the reach of the CT, other factors created limitations. For example, the weld bead on the flowline limited the reach of the CT and required re-evaluating where to create cuts along the flowline. Finally, deploying the CT in a flowline required configuring the injector head horizontally, which required a customized base for safe rig up and operation of the injector head and pressure-control equipment. CT successfully cleaned out five flowlines with IDs ranging from 6-in. to 8-in. and re-established 89% to 98% of their nominal ID. As a result, the operator saved upwards of USD 14 million in flowline replacement costs, increased asset utilization, and decreased deferred injection. Historically, there is limited documented experience with flowline cleanouts using CT. The paper documents a repeatable methodology for candidate selection, planning, execution, and performance evaluation. It also provides basic building blocks to meet treatment design, rig-up, and execution requirements that are unique to this application.

Abstract:
Predictive lifing with probabilistic treatment of key variables represents a promising approach to realizing the digital gas turbine of the future. In this paper, we present a predictive model for creep life assessment of an uncooled turbine blade. The model development methodology draws on well-established machine learning principles to develop and validate a surrogate model for creep life from engine performance parameters. Verified creep life results, obtained from 3D non-linear thermo-mechanical finite element simulation for varying engine operating conditions are used as the basis for model development. The selection of model response surface order is studied over a range of models by evaluating normalized residual error on training and uncorrelated validation data sets. A model that is fully quadratic in the data set features is shown to have excellent predictive capability, yielding nominal creep life predictions to within ± 3% on the validation data set. This work then considers probabilistic techniques to evaluate the impact of uncertainty associated with each key factor on the predicted nominal creep life in order to achieve a mandated life target with a defined probability of failure.

Abstract:
Cam-to-follower clearance influences several aspects of engine operation: valve-train noise, which affects acoustic comfort: valve-train dynamics, which affects engine reliability and functionality; valve lift profile and phasing, which influences combustion cyclic stability especially at idle. If mechanical followers are used on an engine, then, depending on engine operating conditions and different thermal expansion between cylinder head and valve, the valve clearance changes. For this reason the initial and final cam ramps are designed in order to minimize the effects of these variations. When a new valve-train is designed the determination of the nominal valve clearance requires an in-depth knowledge of the above mentioned variations. An experimental evaluation of valve clearance in real engine operating conditions would be desirable. In this paper an extensive experimental activity at engine test bed is presented. A simple, economical and precise indicated methodology was set-up and developed in order to directly measure the angular position of the camshaft when each valve tappet starts to move: in this way valve clearance can be directly determined. These measurements were done in different engine operating conditions with respect to speed and load, and also in thermal and speed transient conditions, in order to determine valve clearance maps. On the intake side a maximum increase of 0.13 mm was found with respect to nominal value, while on the exhaust side a maximum decrease of 0.30 mm was determined. This last value was judged excessive, so some design changes were made in order to limit it: in particular a bi-metallic exhaust valve was tested. The improvement with this type of valve varied from 25% to 70% depending on engine load conditions.

Abstract:
Sheet metal assembly is a common manufacturing process for several products such as automobiles and airplanes. Since all manufacturing processes are affected by variation, the key characteristics or critical dimensions may not be nominal. This paper presents a new fixture design methodology for early evaluation of sheet metal assemblies. Fixture design has been extensively studied for machining processes. Unfortunately, little investigation has been done for sheet metal assembly processes considering the effect of fixture layout on the assembly dimensional variation. The new fixture design methodology is based on classifying the assemblies into three categories depending on the stiffness of the assembly components: rigid-rigid, compliant-rigid and compliant-compliant assembly. Finite Element Analysis (FEA) and design of computer experiments have been used to derive response models for sheet metal assembly applications. The response models are used to analyze the final assembly sensitivity to fixture, part and tooling variation for different assembly configurations. Based on these results several design guidelines are proposed for fixture design on sheet metal assembly.

Abstract:
For safety critical complex systems, reliability and risk analysis are important design steps. Implementing these analyses early in the design stage can reduce costs associated with redesign and provide important information on design viability. In the past several years, various research methods have been presented in the design community to move reliability analysis into the early conceptual design stages. These methods all use a functional representation as the basis for reliability analysis. This paper asserts that, in non-nominal system states, the functional representation limits the scope of failure analysis. Specifically, when failures are modeled to propagate along energy, material, and signal (EMS) flows, a nominal-state functional model is insufficient for modeling all types of failures. To capture possible failure propagation paths, a function-based reliability method must consider all potential flows, and not be limited to the function structure of the nominal state. In this light, this paper introduces the Flow State Logic (FSL) method as a means for reasoning on the state of EMS flows that allows the assessment of failure propagation over potential flows that were not considered in a functional representation of a “nominally functioning” design. A liquid fueled rocket engine serves as a case study to illustrate the benefits of the methodology.

Abstract:
Abstract This paper develops a methodology for the tracking control of satellite formation flight in the presence of external disturbances. The control methodology is composed of two steps. In the first step, an exact control strategy is developed for a nominal system model which provides the best assessment of real-life uncertainties. Upon using results from analytical dynamics, a closed-form control input is derived such that the formation configuration requirements are satisfied. In the second step, an additive robust controller is designed to compensate for the external disturbances to which the satellite formation system may be subjected. A gain adaptation law is developed that automatically updates the control gain in real time to adjust for the presence of environmental disturbances while keeping the precision of the tracking to within user-specified bounds. An additive combination of the two controllers enables precision tracking control for the satellite formation without a priori information about the bounds on the uncertainties and disturbances imposed on the formation system. Numerical simulations demonstrate the accuracy and effectiveness of the proposed two-step control methodology in which a desired formation configuration is to be maintained under unknown environmental disturbances.
