Résumé :
Bodyweight—the number on the scale—has been constructed as an objective measure of health, and weight loss as synonymous with healthier. Weight has been used as a way of classifying and controlling people, ignoring the embodied, relational, and cultural meanings attached to health and weight. Instead, these subjective experiences are lumped into a numerical category. Our society's obsession with weight is weighing us down and most of us should toss out our scales. Scale stories offer a departure from canonical narratives about physical health and body image by emphasizing emotions and lived experiences instead of bodyweight and numerical categories.

Résumé :
Abstract In this paper, we discuss coin-weighing problems that use a 5-way scale which has five different possible outcomes: MUCH LESS, LESS, EQUAL, MORE, and MUCH MORE. The 5-way scale provides more information than the regular 3-way scale. We study the problem of finding two fake coins from a pile of identically looking coins in a minimal number of weighings using a 5-way scale. We discuss similarities and differences between the 5-way and 3-way scale. We introduce a strategy for a 5-way scale that can find both counterfeit coins among 2k coins in k + 1 weighings, which is better than any strategy for a 3-way scale.

Résumé :
This main objective of this research was to design an energy efficient, hybrid digital weighing scale which can be used in all weight measuring operations. It is basically designed to take weights in kg and display on LCD. The design is justified on the basis of the purpose and importance of weight machine in various aspects. This machine can detect minute magnitude of weight placed over it and can accurately measure in kilograms and displays it over a digital scale. It could be used in homes, industries, shops and retail outlets for determining the weights of the various materials being sold to the customers so that the items may be correctly rated as per the displayed weight over the machine. It converts pressure into appropriate voltage levels. This voltage level is filtered and converted into digital data in the microcontroller which is then displayed on a LCD.

Résumé :
A central focus of computational biology is to organize and make use of vast stores of molecular sequence data. Two of the most studied and fundamental problems in the field are sequence alignment and phylogeny inference. The problem of multiple sequence alignment is to take a set of DNA, RNA, or protein sequences and identify related segments of these sequences. Perhaps the most common use of alignments of multiple sequences is as input for methods designed to infer a phylogeny, or tree describing the evolutionary history of the sequences. The two problems are circularly related: standard phylogeny inference methods take a multiple sequence alignment as input, while computation of a rudimentary phylogeny is a step in the standard multiple sequence alignment method.Efficient computation of high-quality alignments, and of high-quality phylogenies based on those alignments, are both open problems in the field of computational biology. The first part of the dissertation gives details of my efforts to identify a best-of-breed method for each stage of the standard form-and-polish heuristic for aligning multiple sequences; the result of these efforts is a tool, called Opal, that achieves state-of-the-art 84.7% accuracy on the BAliBASE alignment benchmark. The second part of the dissertation describes a new algorithm that dramatically increases the speed and scalability of a common method for phylogeny inference called neighbor-joining; this algorithm is implemented in a new tool, called NINJA, which is more than an order of magnitude faster than a very fast implementation of the canonical algorithm, for example building a tree on 218,000 sequences in under 6 days using a single processor computer.

Tudor, Joshua. « Developing a national frame of reference on student achievement by weighting student records from a state assessment ». Diss., University of Iowa, 2015. https://ir.uiowa.edu/etd/1779.

Texte intégral
Résumé :
A fundamental issue in educational measurement is what frame of reference to use when interpreting students’ performance on an assessment. One frame of reference that is often used to enhance interpretations of test scores is normative, which adds meaning to test score interpretations by indicating the rank of an individual’s score within a distribution of test scores of a well-defined reference group. One of the most commonly used frames of reference on student achievement provided by test publishers of large-scale assessments is national norms, whereby students’ test scores are referenced to a distribution of scores of a nationally representative sample. A national probability sample can fail to fully represent the population because of student and school nonparticipation. In practice, this is remedied by weighting the sample so that it better represents the intended reference population. The focus of this study was on weighting and determining the extent to which weighting grade 4 and grade 8 student records that are not fully representative of the nation can recover distributions of reading and math scores in a national probability sample. Data from a statewide testing program were used to create six grade 4 and grade 8 datasets, each varying in its degree of representativeness of the nation, as well as in the proximity of its reading and math distributions to those of a national sample. The six datasets created for each grade were separately weighted to different population totals in two different weighting conditions using four different bivariate stratification designs. The weighted distributions were then smoothed and compared to smoothed distributions of the national sample in terms of descriptive statistics, maximum absolute differences between the relative cumulative frequency distributions, and chi-square effect sizes. The impact of using percentile ranks developed from the state data was also investigated. By and large, the smoothed distributions of the weighted datasets were able to recover the national distribution in each content area, grade, and weighting condition. Weighting the datasets to the nation was effective in making the state test score distributions more similar to the national distributions. Moreover, the stratification design that defined weighting cells by the joint distribution of median household income and ethnic composition of the school consistently produced desirable results for the six datasets used in each grade. Log-linear smoothing using a polynomial of degree 4 was effective in making the weighted distributions even more similar to those in the national sample. Investigation of the impact of using the percentile ranks derived from the state datasets revealed that the percentile ranks of the distributions that were most similar to the national distributions resulted in a high percentage of agreement when classifying student performance based on raw scores associated with the same percentile rank in each dataset. The utility of having a national frame of reference on student achievement, and the efficacy of estimating such a frame of reference from existing data are also discussed.

Texte intégral
Résumé :
Asian-Americans are the fastest growing ethnic minority group in the United States, followed by Hispanics. Little is known about their health state preferences or their health status. The purpose of this research was to determine whether a Chinese-American population has different preference values on four dimensions of health status than a general community sample in the United States. Also of interest was the self-reported health status of this sample of Chinese-Americans, using weights derived from Americans or Chinese-Americans to see whether the resulting index scores were significantly different. The question is whether Quality of Well-Being (QWB) weights derived from preferences of the American sample were appropriate for scoring QWBs for the Chinese-Americans. This research was conducted on 383 Chinese-Americans living in the San Gabriel Valley area, east of Los Angeles, California. A model of deliberate sampling for heterogeneity and a snowball sampling strategy were used for subjects' selection into the study. Three instruments (a weighting booklet, the Quality of Well-Being Scale, and a demographic battery), each having an English and a Chinese version, were used. Results indicate that the reliability and validity of the booklet rating and QWB Scale were high in the Chinese-American sample. The preference weights derived from the sample of Chinese-Americans were different from those derived from the community sample of Americans. Although the weights cannot be compared individually due to the lack of variance associated with them, of those 48 levels on the symptom/problems scale, 28 of the Chinese-American weights were lower than the American weights. For the 11 levels of the three functional scales, eight were higher than the American sample. The mean QWB scores calculated using Chinese-American weights were lower than those calculated using American weights. Therefore, QWB weights derived from preferences of the American sample were not appropriate for scoring QWBs for the Chinese-Americans.

Mestrado em Finanças
Este trabalho apresenta um estudo empírico sobre cumulative prospect theory através do estudo da função de utilidade e a função de probabilidade distorcida. Os resultados obtidos estão de acordo com a literatura, que mostra que a função da utilidade é côncava no domínio dos ganhos, e quase linear no domínio das perdas. Não só mostra que a função da probabilidade distorcida tem a forma de um "S" inverso tanto no domínio dos ganhos como no domínio das perdas. Também aborda o estudo de variáveis demográficas relacionando-as com os coeficientes das funções mencionadas anteriormente, concluindo assim que os homens estão mais dispostos a correr riscos do que as mulheres. Por fim, através dos coeficientes calculados, foi possível aplicar os resultados ao mercado financeiro. Primeiro criando uma ponte entre o coeficiente de loss aversion e a escala de DOSPERT, o que irá facilitar a determinação do carteira mais adequado para cada individuo. Segundo, aplicando a cumulative prospect theory à modern portfolio theory para o mercado Português. Isto irá permitir que as instituições financeiras consigam determinar a carteira óptima do mercado, tendo em conta as probabilidades distorcidas.
This work presents an empirical study of the cumulative prospect theory using a Portuguese sample. We estimate the value function and the probability weighting function with positive and negative outcomes. The results confirm previous works that the value function is concave in the gain domain and almost linear in the loss domain. Our results also show an inverse S-shape for the probability weighting function in both loss and gain domain. We also look into the relation of the coefficient from the already mentioned functions with some demographic variables. It was possible to conclude that males are more willing to take risks than females. Finally, using the calculated coefficients we discuss the applicability of the results in the context of financial markets. First we establish a bridge between the loss aversion coefficient and the DOSPERT-scale, which will provide an easier way for financial institutions to present the correct efficient portfolio for each individual. Second we apply the cumulative prospect theory to the modern portfolio theory, for the Portuguese market. This will allow the financial institutions to create an efficient portfolio of the market, taking into account the probabilities distortions

Résumé :
Cette thèse revisite les relations entre les processus attentionnels visuels et la perception de qualité. Nous nous intéressons à la perception de dégradation dans des séquences d’images et leur impact sur la perception de qualité. Plutôt qu’un approcha globale, nous travaillons à une échelle spatio temporelle fine, plus adaptée aux décisions des encodeurs vidéo. Deux approches liant attention visuelle et qualité perçue sont explorées. La première, suit une approche classique, de type pondération des distorsions. Ceci est mis en relation avec des scénarios d’usage comme le streaming interactif ou la visualisation de contenus omnidirectionnels. Une seconde approche nous amène à introduire le concept de disruption visuelle (DV) et sa relation avec la perception de qualité. Nous proposons d’abord des techniques permettant d’étudier les saccades résultantes de la DV à partir par de données expérimentales oculométriques. Nous proposons ensuite un modèle computationnel de prédiction de la DV. Une nouvelle mesure objective de qualité est ainsi introduite nommée "Disruption Metric" permettant l’évaluation de la qualité locale de vidéos. Les résultats obtenus trouvent leurs applications dans de nombreux domaines tels que l’évaluation de qualité, la compression, la transmission perpétuellement optimisée de contenus visuel ou le rendu/visualisation foéval
This thesis revisits the relationship between visual attentional processes and the perception of quality. We mainly focus on the perception of degradation in video sequences and their overall impact on our perception of quality. Rather than a global approach, we work in a very localized spatio-temporal scale, more adapted to the decision-process in video encoders. Two approaches linking visual attention and perceived quality are explored in the thesis. The first follows a classical approach, of the distortion weighting type. This is very useful in certain scenarios such as interactive streaming or visualization of omni-directional content. The second approach leads us to the introduction of the concept of visual disruption(DV), and explore its relation to perceived quality. We first propose techniques for studying the saccades related to DV from experimental oculometric data. Then, a computational model for the prediction of DV is proposed. A new objective measurement of quality is therefore born, which we call the "Disruption Metric" : that allows the evaluation of the local quality of videos. The results obtained, find their applications in many fields such as quality evaluation, compression, perpetually optimized transmission of visual content or foveated rendering / transmission

Résumé :
There is an increasing trend towards object detection from aerial and satellite images. Most of the widely used object detection algorithms are based on local features. In such an approach, first, the local features are detected and described in an image, then a representation of the images are formed using these local features for supervised learning and these representations are used during classification . In this thesis, Harris and SIFT algorithms are used as local feature detector and SIFT approach is used as a local feature descriptor. Using these tools, Bag of Visual Words algorithm is examined in order to represent an image by the help of histograms of visual words. Finally, SVM classifier is trained by using positive and negative samples from a training set. In addition to the classical bag of visual words approach, two novel extensions are also proposed. As the first case, the visual words are weighted proportional to their importance of belonging to positive samples. The important features are basically the features occurring more in the object and less in the background. Secondly, a principal component analysis after forming the histograms is processed in order to remove the undesired redundancy and noise in the data, reduce the dimension of the data to yield better classifying performance. Based on the test results, it could be argued that the proposed approach is capable to detecting a number of geo-spatial objects, such as airplane or ships, for a reasonable performance.

Résumé :
This work focuses on analysing and improving feature detection and matching. After creating an initial framework of study, four main areas of work are researched. These areas make up the main chapters within this thesis and focus on using the Scale Invariant Feature Transform (SIFT).The preliminary analysis of the SIFT investigates how this algorithm functions. Included is an analysis of the SIFT feature descriptor space and an investigation into the noise properties of the SIFT. It introduces a novel use of the a contrario methodology and shows the success of this method as a way of discriminating between images which are likely to contain corresponding regions from images which do not. Parameter analysis of the SIFT uses both parameter sweeps and genetic algorithms as an intelligent means of setting the SIFT parameters for different image types utilising a GPGPU implementation of SIFT. The results have demonstrated which parameters are more important when optimising the algorithm and the areas within the parameter space to focus on when tuning the values. A multi-exposure, High Dynamic Range (HDR), fusion features process has been developed where the SIFT image features are matched within high contrast scenes. Bracketed exposure images are analysed and features are extracted and combined from different images to create a set of features which describe a larger dynamic range. They are shown to reduce the effects of noise and artefacts that are introduced when extracting features from HDR images directly and have a superior image matching performance. The final area is the development of a novel, 3D-based, SIFT weighting technique which utilises the 3D data from a pair of stereo images to cluster and class matched SIFT features. Weightings are applied to the matches based on the 3D properties of the features and how they cluster in order to attempt to discriminate between correct and incorrect matches using the a contrario methodology. The results show that the technique provides a method for discriminating between correct and incorrect matches and that the a contrario methodology has potential for future investigation as a method for correct feature match prediction.

Résumé :
In current time, the calculations of population of bee for honey strictly increase. So that's why here i am going to discuss that how i can get the weight of bee population for honey. I am taking two kinds of technology like bluetooth and wi-fi. One more is hardware design weighingmachine.so i can get the bee population by using bluetooth and wi-fi module .Bluetooth module and wi-fi module are attached in weighing machine and all are controlled by programming. Bluetooth can measure the weight in small range but wi-fi will work as cloud service in which we can calculate the weight in every 15 second by python programming. Also i got the database server to store all intermediate results and also i can delete all results. There is load cell by using, i can measure up to 5 kg weight. Firstly this weigh goes to ADC (analogue to digital converter) to convert the weight into digital weight, after that is weight will go to microcontroller to control all weight to the led, wi-fi module, bluetooth module. here i use power plug source to get the electricity. Bluetooth shows only weight is bee population but wi-fi service does not only shows the result but also it stores in database server in every 15 seconds that's why i do not have to go for checking weight to reach at particular place for our goal weight.

Ship convoys in the southern part of the Suez Canal can only travel in a single lane, therefore the grounding of the Ever Given effectively blocked all traffic through the Canal. The six-day blockage exacted a heavy financial price and loss of revenues for Egypt and for consumers worldwide. When the Ever Given was finally freed, she was arrested by Egyptian authorities and detained for over three months, while all her cargo worth hundreds of millions of dollars could not reach its various destinations, causing further financial losses and claims. This incident demonstrates the vital importance that Suez Canal holds for global maritime trade by considerably shortening the route between the Far East and Europe and the Americas (as an alternative to journeying around Africa). However, it highlights the consequences of failure to adapt to the pace of growth of container ships in the last two decades, and the lack of preparedness of the Suez Authorities to deal with an event of such magnitude. The race to increase profitability by economies of scale has a profound global impact on shipping and ports. The article discusses the regulatory regime of this vital waterway in the context of responsibilities, liability, and cooperation between Suez Canal authorities and ships’ commands. The lack of clarity regarding legal relationships between national authorities, ship operators, and masters is discussed with emphasis on straits, narrow passages, rivers, and channels.

Résumé :
In 2015 the existing scale for aircraft weighing failed calibration. The item was calibrated to the European standard for pressure calibration. This standard is more precise than the international standard. New items of same manufacturer passed calibration by the manufacturer and the international standard but also failed the European standard. Intensive market research showed that there is no scale on the market calibrated to the European standard with the precision needed. German Armed Forces was forced to look for a company with enough experience in the construction of pressure scales to construct the scale needed. The presentation will demonstrate the way of procurement of the scales, and also discuss solving problems that arose in getting the item into service.

Résumé :
In the pharmaceutical laboratory, weighing is only one step of a whole analysis chain in drug discovery and quality control; however it strongly influences the overall quality and integrity of the final result. Also in production, weighing is decisive to achieve batch uniformity and consistency, e.g. in dispensing or formulation processes. For the food industry, accurate weighing processes also act as an important contribution for two of its most demanding challenges: Increasing public health and consumer safety, and increasing productivity and competitiveness. The same or similar issues are also prevalent in other industries as the chemical, fragrance or automotive industry, and also apply for testing labs and companies focusing on contract research and manufacturing. Everywhere, accurate weighing is essential to ensure continuous adherence to predefined process requirements and to avoid a frequent source of Out of Specification results (OOS). This article introduces GWP®, a science-based global standard for efficient lifecycle management of weighing systems. It consists of the selection of the appropriate weighing system based on the evaluation of the respective weighing process requirements, and provides scientific guidance to the user regarding calibrating and testing weighing instruments during the instrument's lifecycle. Based primarily on the user’s weighing requirements and prevailing weighing risks, it provides a state-of-the-art strategy to reduce measurement errors and to ensure reproducibly accurate weighing results. The understanding of the particular weighing process requirements and important balance and scale properties as minimum weight is essential to select an appropriate weighing system in the framework of the design qualification. The performance qualification takes into account these requirements and risks to establish a specific routine testing scenario for the instrument. The higher the impact in case of inaccurate weighings, and the more stringent the weighing accuracy requirements are the more frequently calibration and user tests have to be carried out. However, for less risky and stringent applications, testing efforts can be reduced accordingly. Risk- and life cycle management form an integrated part of the overall strategy of GWP® to bridge the gap between regulatory compliance, process quality, productivity and cost consciousness.

Résumé :
In Sri Lanka, small scale spice packaging businesses use traditional methods while middle scale spice packaging businesses use separate machineries for each individual tasks such as weighing, filling, and sealing processes. Comparatively, considering the higher demand for large-scale spice products in the market, they use highly expensive, technically improved, automated machinery. According to the researches and the site visits, it is observed that currently, there is no affordable packaging machine available in the local market for middle scale businessmen, which includes all weighing, filling and sealing processes in a single system. Therefore, it limits their profits and production. The current used methods in middle scale businesses cause high wastage of raw materials, less accuracy, less hygienic, higher labor costs, and low efficiency. This project proposes a semi-automated, Arduino based machinery for middle scale spice packaging business where a packet is fed manually to the system, while weighing, filling, and sealing processes are automated and sequentially completed. The operation of this machine can be carried out with an involvement of a single laborer. The designed product is pneumatic based and uses some sensors for position, weighing and level detection, heating element, stepper motors, pneumatic system components for smooth operation and Arduino as the micro controller to make it cost effective. With this innovative structure, three packets can be filled and sealed within fifteen seconds while the current used method takes fifteen seconds to complete this process for a single packet. Cost and time effectiveness, reducing ingredient wastage and labor cost are the main advantages of this project. Due to the COVID-19 health restrictions, the hardware implementation is partially completed but to illustrate the working principle and the design plan, a 3D animated model was implemented using SolidWorks, incorporated with electrical stimulation in the Proteus software package. KEYWORDS: Packaging-machine, Middle-scale, Pneumatics, Weighing, Sealing, SemiAutomated.

Widespread misconceptions • specifically in respect to the definition of test procedures and the selection of appropriate weights for periodic performance verification • are critically analyzed. Based on scientific principles the user is guided on how to optimize his routine testing procedures and how to avoid unnecessary or even erroneous testing.

Résumé :
In 2015, the Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data at Mesa Verde National Park (MEVE). Between July and August 2015, as well as February and March 2016, three acoustical monitoring systems were deployed throughout the park, however one site (MEVE002) stopped recording after a couple days during the summer due to wildlife interference. The goal of the study was to establish a baseline soundscape inventory of backcountry and frontcountry sites within the park. This inventory will be used to establish indicators and thresholds of soundscape quality that will support the park and NSNSD in developing a comprehensive approach to protecting the acoustic environment through soundscape management planning. Additionally, results of this study will help the park identify major sources of noise within the park, as well as provide a baseline understanding of the acoustical environment as a whole for use in potential future comparative studies. In this deployment, sound pressure level (SPL) was measured continuously every second by a calibrated sound level meter. Other equipment included an anemometer to collect wind speed and a digital audio recorder collecting continuous recordings to document sound sources. In this document, “sound pressure level” refers to broadband (12.5 Hz–20 kHz), A-weighted, 1-second time averaged sound level (LAeq, 1s), and hereafter referred to as “sound level.” Sound levels are measured on a logarithmic scale relative to the reference sound pressure for atmospheric sources, 20 μPa. The logarithmic scale is a useful way to express the wide range of sound pressures perceived by the human ear. Sound levels are reported in decibels (dB). A-weighting is applied to sound levels in order to account for the response of the human ear (Harris, 1998). To approximate human hearing sensitivity, A-weighting discounts sounds below 1 kHz and above 6 kHz. Trained technicians calculated time audible metrics after monitoring was complete. See Methods section for protocol details, equipment specifications, and metric calculations. Median existing (LA50) and natural ambient (LAnat) metrics are also reported for daytime (7:00–19:00) and nighttime (19:00–7:00). Prominent noise sources at the two backcountry sites (MEVE001 and MEVE002) included vehicles and aircraft, while building and vehicle predominated at the frontcountry site (MEVE003). Table 1 displays time audible values for each of these noise sources during the monitoring period, as well as ambient sound levels. In determining the current conditions of an acoustical environment, it is informative to examine how often sound levels exceed certain values. Table 2 reports the percent of time that measured levels at the three monitoring locations were above four key values.
