Abstract:
We propose studying the variations of volume of implicit objects during an animation according to several points of view: choice of the function of density, variations of parameters such as the iso-value and the radius of influence for a given function, variations of the parameters inherent in a particular function. Modification of parameters of the function of density must be carried out with care. There are no rules concerning these variations. To avoid the non-monotonous variations, it is necessary to choose a function of density beforehand and study the intervals of variation of its parameters. A new discretization makes it possible to locate these variations for a later use in a process of control of these variations.

Abstract:
Marine diesel engine excitation can occur from the cycle-to-cycle variation in the engine output. The cycle-to-cycle variation in maximum cylinder pressure (Pmax) is often used to represent this variation. Earlier studies examined the correlation between the cycle-to-cycle variation in the maximum cylinder pressure (Ρmax), pressure impulse (PI) and ignition delay (ID) for the case of constant injection setting. This paper summarizes the results of systematic experiments to determine the cycle-to-cycle variations when the injection timing is changed. In these tests the cycle-to-cycle variations in the maximum cylinder pressure (Pmax), ignition delay (ID), and corresponding pressure impulse (PI) are examined for a single-cylinder test diesel engine at various speeds and compression ratios. Comparisons show that the cycle-to-cycle variations of the diesel engine power output are strongly affected by the injection timing. The best parameter for describing the cycle-to-cycle output variation is shown to depend on the specific engine test condition.

Full text
Abstract:
This thesis investigates the effect(s) that deliberate and systematic use of dimensions of variation (DoV) in the teaching of mathematics can have for the students' learning. Variation theory, together with its practical application as an educational approach, is introduced (Marton and Booth, 1997). A realistic quasi-experimental longitudinal intervention called the Dimensions of Variation Programme, DVP, was designed and implemented to examine how this approach can potentially influence the understanding of students in algebra classrooms. The design was realistic because careful consideration was given to how the realities of the educational environment 'could be appropriately incorporated into the intervention in order to increase pragmatic validity. Convenience sampling was used to obtain a cohort of approximately 300 students. This sample corresponded to ten intact classes drawn from eight Oxfordshire schools. Six of the classes were taught by intervention teachers with the remaining four classes being taught by comparison teachers. The students were followed over a 14 month period between Year 7 and Year 8. The intervention teachers formed a research community which met regularly to discuss and jointly plan how the algebra content could be handled with awareness to dimensions of variation. o Classes were observed for eight lessons in total during the 14 months, four consecutive algebra lessons at the beginning of the intervention and four consecutive lessons toward .the end of the intervention. During these observations the mathematical dimensions of variation, together with some contextual details, were recorded. This formed the predictive data for the study. The students were pre-, post-, and delayed post-tested using national SAT exams. Scores from these were used as the primary outcome measure. These data were subsequently analysed both qualitatively and quantitatively in order to identify any differences that might exist between the intervention and comparison groups. The findings suggest that the intervention teachers handled the content in qualitatively different ways to the comparison teachers. The principle distinguishing characteristic between groups was that the intervention teachers exhibited an awareness for 'systematicity of inference' while the comparison teachers did not. There is some evidence to suggest that the intervention significantly affected students' learning outcomes in algebra between Year 7 and Year 8.

This dissertation presents a variationist analysis of syntactic variation and change in modern spoken Afrikaans. The Afrikaans language community is heterogeneous, and can be divided into different communication communities according to patterns of segregated residential settlement and limited social interaction (linked to South Africa's history of apartheid). The selection of a sample for the study is informed by these realities and the sample is kept deliberately homogenous (following Barbiers, Cornips and Van der Kleij, 2000): participants (N=34) are White middle-class speakers of Afrikaans who are under 36 years of age and have been residing in Cape Town for at least the past seven to ten years. In addition, all participants are bilingual in English (as established through an electronically administered language use survey).In order to combine formal theory (generative linguistics) withΓÇó empirical analysis (sociolinguistics), the methodology follows a bi-modal approach. Both performance and competence are considered, and arguments are based on two types of data: speech data (interviews, narrative picture descriptions) and grammaticality judgements (elicited by means of an oral questionnaire). Grosjean's (2001) language mode model assists in refining the methodology of the study, because it recognises the fact that a bilingual speaker is a unique speaker-hearer (Chomsky, 1965). The empirical data are elicited in near-monolingual Afrikaans language modes. The results are quantified according to token frequencies and analyzed in comparison to other studies; significance tests are carried out using Chi-square and Fisher's exact tests. From the literature, the consensus seems to be that the word order in Afrikaans (XV structure) is changing to resemble an English frame (VX structure) because of language contact (cf, inter alia, Conradie, 2004; Donaldson, 1991). Two syntactic variables are studied to investigate variation in word order and verb placement: firstly, changes from XV to VX in subordinate clauses are explored by looking at the use of specific types of subordinate clauses, and the impact of matrix clause bridge verbs on complementizer omission and dependent/independent word order in the speech corpora. Secondly, the study examines the use of direct linking verbs and the role that complex verb initials play in proliferating VX structures. The findings are as follows: with embedded clause word order, the corpus data provides evidence of the frequent use of complementizer-less VX subordinate clauses that were not formally elicited in the questionnaire. These clauses have an important impact on variation in Afrikaans word order, leading to the proliferation of VX embedded clauses. Contributing factors are the weakening of the complementizer's semantic strength, and the role of the bridge verb as quotative marker in the matrix clause. Furthermore, the corpus data shows high frequencies of non-standard complementizer-led VX clauses, especially when compared to their low meta-linguistic acceptance in the questionnaires. The data thus shows significant variation in embedded clause word order and suggests that we are witnessing a change in progress for this variable. With respect to complex verb initials, the study finds a high acceptance rate in the questionnaires, as well as regular use in the spoken language corpus. By comparing the use of complex verb initials to a previous study (Ponelis, 1993) the study establishes a change in real time where an increase in the use of complex verb initials promotes the suspension of the main verb in clause-final position (V-final). The study recommends that that the bi-modal approach of considering both performance and competence data should be applied to similar studies of other groups in the Afrikaans language community.

Abstract:
The present study responds to the longstanding need within the field of applied sociolinguistics for a better understanding of L2 variability. The study is concerned with the nature of phonological variation in the use of English by Indians. It is an attempt to use sociolinguistic methodology In examInIng a second language situation and to investigate: 1. Whether L2 variability is conditioned by linguistic constraints, and 2. Whether there is any social significance associated with L2 variability. The study is based on the data collected from 44 educated speakers of English in Aligarh (North India). The data was analysed by means of a variety of statistical and computer based programmes. Forty five minutes long interview was conducted by means of a questionnaire. The tasks, ranging from the informal to the most formal, were: (i) casual speech, (ii) short responses or interview style, (iii) reading passage and sentences, and (iv) reading minimal paIrs. There was, of course, no way to eliminate completely the influence of the interview situation, which generally causes speech to be more formal than casual. However, a number of techniques were used to enable the informants to relax and speak more casually. The first chapter deals with the socio-cultural and historical aspect of English in India. The second chapter looks at various theoretical approaches to the study of linguistic variability. The third chapter discusses the research methodology adopted for the present study. The fourth chapter examines the linguistic variants in different phonolog'ical environments and confirms our hypothesis that linguistic variation in second language IS systematic at the level of both the individual and the group. In the fifth chapter phonological variables have been analysed in relation to social demographic variables, such as schooling, education, age, sex and social class. The analysis in the sixth chapter deals with stylistic variation and shows a wide variation in different styles of speech. The seventh chapter very briefly examines intelligibility of Indian English and suggests that a change is probably taking place in Indian English due to social and political pressures within the country, particularly affecting younger generation. The last chapter begins with a brief discussion of the major findings and their social and linguistic implications and suggests ways in which the insights gained from the study can be utilised in the teaching of English as a second language.

Abstract:
This thesis 1S a data-oriented sociolinguistic study of linguistic variation 1n the spoken variety of the Arabic-speaking speech community of Khartoum (capital of the Sudan). It sets out to investigate some salient phonological and morphological variables and their correlation with some social parameters. The reciprocal influences of the Classical and the Colloquial Arabic varieties are measured quantitatively in the data elicited through structured interviews from specific social groups whose members were randomly selected. Relation of norms of appropriateness' to actual linguistic behaviour is also investigated. Chapter One provides a brief account on the general characteristics of the linguistic situation in the country, a short review of the previous dialectological studies, the range and social evaluation of the major varieties of Arabic and a discussion of the theoretical problems involved in the distinction of context-specific varieties in Arabic. Chapter Two gives a brief survey of the major approaches to the study of linguistic variation and describes the theoretical framework of the study. Chapter Three discusses the methodological questions pertaining to data collection in the relevant area and describes the method followed in the study. Chapter Four presents the phonological variables and discusses their variants. Chapter Five deals with results and analysis of each phonological variable for each social group. Explanations are attempted as to the different patterning of variables in the linguistic behaviour of the different social groups. A small unquantified data on the 'feminine variety' is presented with reference to the lexical and supra-segmental features. Chapter Six discusses two grammatical features: the future tense marker and the demonstrative. Results and analysis of the study are presented with discussion. Chapter Seven provides a summary of the major types of variation in Sudanese Arabic with discussion of the main findings of the study and some of their methological and theoretical implications. These are then followed by appendices presenting questionnaires relevant to the study.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.
Includes bibliographical references (p. 149-152).
Aggressive technology scaling raises the need for efficient methods to characterize and model circuit variation at both the front and back end of line, where critical parameters such as threshold voltage and parasitic capacitance must be carefully modeled for accurate circuit performance. This thesis addresses this need by contributing a test circuit methodology for the extraction of spatial, layout and size dependent variations at both device and interconnect levels. The test chip uses a scan chain approach combined with low-leakage and low-variation switches, and Kelvin sensing connections, providing access to detailed analog device characteristics in large arrays of test devices. Front end of line (FEOL) test structures include transistors of different sizes, number of polysilicon fingers, polysilicon fingers proximity, and orientation, for both NMOS and PMOS MOSFETs. Back end of line (BEOL) test structures include parasitic coupling, plane to plane and crossover capacitances, measured using a charge-based capacitive measurement (CBCM) methodology integrated with switches in the scan chain. The testing of the designed test chip has proven successful for both device and interconnect test structures.
(cont.) Different layout practices in both NMOS and PMOS transistors are seen to result in significant differences in mean and standard deviation of measured output current, with 95% confidence or more. The FEOL structure analysis shows strong dependencies between layout practices: orientation offers a consistent but opposite offset in NMOS and PMOS transistors and variation increases for gate lengths split among fingers. Variation due to sizing follows Pelgrom's model, showing that variation increases for smaller gate lengths and widths, in both NMOS and PMOS transistors. Threshold voltage extraction and variation analysis also demonstrate how variation increases for smaller features. BEOL capacitances were extracted and sub-femto Farad changes were detected for capacitive test structures. Spatial analysis reveals a large die-to-die trend in device performance. The parameter extraction and variation analyses made possible by the variation test chip enable the identification of likely variation sources, quantification of circuit impact and sensitivity, and specification of layout practices for variation minimization.

Abstract:
Variation is a fundamental concept in statistics literacy; standard deviation is part of compulsory school curriculum in Brazil. The objective of this study is to explore reasoning about variability by teachers, using the model proposed by Garfield (2002). The sample was composed of nine in-service mathematics teachers who took part in a teacher-training course on statistics. An experimental focus made it possible for them to experience all the steps of a statistics research project in which the course content was designed to expose the reasoning about variability employed by these teachers. We identified an oscillation between idiosyncratic and procedural levels, but no teacher showed complete reasoning about variation. The most prevalent reasoning employed was verbal, when teachers interpreted standard deviation as a measure of variation among observations.

Abstract:
While recent and ongoing research has begun to reveal ways that precollege students think about variation, more research has been needed to understand the conceptions of variation held by elementary preservice teachers and also how to shape the university courses where those preservice teachers learn. This paper, sharing an excerpt from an exploratory study aimed at preservice teachers, describes changes in class responses to a sampling task where variation is a key component. Overall, going from before to after a series of instructional interventions, responses reflected a more appropriate sensitivity to the presence of variation.
