There is often more than one way to select tonal adjustment for a photograph, and different individuals may prefer different adjustments. However, selecting good adjustments is challenging. This thesis describes a method to predict whether a given tonal rendition is acceptable for a photograph, which we use to characterize its range of acceptable adjustments. We gathered a dataset of image "acceptability" over brightness and contrast adjustments. We find that unacceptable renditions can be explained in terms of over-exposure, under-exposure, and low contrast. Based on this observation, we propose a machine-learning algorithm to assess whether an adjusted photograph looks acceptable. We show that our algorithm can differentiate unsightly renditions from reasonable ones. Finally, we describe proof-of-concept applications that use our algorithm to guide the exploration of the possible tonal renditions of a photograph.

Harris, Lee Davis. "A Study of Intensity Control in Males with Developing Voices: Implications for Pitch Range and Tessitura." Thesis, University of North Texas, 1996. https://digital.library.unt.edu/ark:/67531/metadc277974/.
Full textAbstract:
Research on voice change in males has generally fallen into two categories: music education studies of changes in the singing voice and speech studies of changes in the speaking voice. These studies rarely consider differences in the dynamic ability of male singers at different stages of vocal development. The concept of tessitura, a portion of the vocal range in which the singer sounds best, is referred to in the literature on vocal music, but the means for identifying its size and location within the range have not been consistently specified. Tessitura appears to be a portion of the range which is most controllable in terms of dynamics and agility and is optimal in tonal quality. This study used the phonetograph to investigate differences in measures of intensity control between pre-pubertal, pubertal (changing) and post-pubertal voices in 48 males aged 9 to 18 years old. These intensity measures were compared to ratings of vocal effort from a panel of 4 music educators in order to determine if tessitura could be identified from acoustic and perceptual evidence of an optimum vocal area.
Results of the study were: 1) post-pubertal voices demonstrated greater control of vocal intensity as revealed in lower mean minimum and comfortable intensity measures, higher overall maximum intensity measures and a larger minimum-to-maximum intensity range; 2) intensity measures for pubertal voices were similar to those observed in pre-pubertal voices, contrary to trends suggested in the literature on voice change; 3) the Greatest Dynamic Range (GDR) on the phonetograph, indicating the range in which singers had the most dynamic control, was smaller than the range in which the singers were judged to sound best; 4) tessitura originated in the lower portion of the vocal range, around the location of mean speaking fundamental frequency. Although registers were not specifically investigated, tessitura appeared to be primarily related to modal register in singers who had completed voice change.

The paper deals with the auditory analysis of the tonal features of English urban static-and-dynamic landscape descriptions. The auditory analysis made by phoneticians resulted in distinguishing the tonal parameters of urban landscape descriptions under study. They are: medium and raised ascending on-set; checked head, gradually descending stepping head and gradually descending stepping broken head; low and medium falling terminal tone; narrowed tonal range in static parts and the medium, broadened and broad tonal range in dynamic parts; zero tonal interval between adjacent intonation groups and segments of their intonation contour.

Full textAbstract:
Abstract The salt print is an important part of photography, both in its historic value and in the tonal range it can provide. This tonal range is greater than any other photographic printing process available to date attributed to the inherent masking ability of the metallic silver. However the intrinsic production problems have made it a 'forgotten' process. There are five key problems. 1. The difficulties in achieving the potential extensive tonal range. 2. The varying colour of the print. 3. Staining that appears in the print, during and after processing. 4. Instability and longevity of the salt print. 5. Contradictory and inaccurate information in material published on the salt print. Although the emphasis of the research is on exploring and controlling the colour and tonal range, the staining problems and stability of the print are also addressed. The materials used for contact negatives today vary in both capture and output, from analogue film processed in the traditional wet darkroom to a variety of transparent film printed from digital files. Inadequate density and tonal range can affect all types of negatives. To provide sufficient exposure time for the salt prints extended tonal range adjustments to the negative were necessary. These long exposures then converted sufficient silver salts to the image making metallic silver, utilising the intrinsic self-masking process. Ultimately this research has uncovered ways to control colour and tonal range and certain aesthetic qualities of the salt print, while simultaneously resolving some of the conflicts in published information. Accurate and consistent methods of processing eliminate staining, providing some stability to the print. The activities and steps carried out to make a salt print are manual; precise duplication is therefore almost unattainable. Nevertheless, although tests on a densitometer may display numeric differences, visual differences are barely noticeable.

Les tècniques d'imatge d'alt rang dinàmic (HDR) potencialment permeten la captura i l'emmagatzematge de tota la informació de llum en una escena. No obstant això, els dispositius comuns de visualització són limitats en termes de les seves capacitats de contrast i brillantor, per tant, les imatges HDR han de ser mapejades tonalment abans de presentar-les en un dispositiu de visualització per assegurar que es reprodueix l'aspecte original de l'escena. En aquesta tesi, es prenen dos enfocaments del problema de mapeig tonal. En primer lloc, es desenvolupa un marc general per a la millora de qualsevol imatge mapejada tonalment mitjançant la reducció de la distància a la corresponent imatge HDR en termes d'una mètrica perceptiva no local. La distància es redueix al mínim per mitjà d'un algoritme de descens de gradient. En segon lloc, es desenvolupa un operador de mapeig tonal (TMO) en temps real que s'adapta bé a les estadístiques d'escenes naturals, i concorda amb els nous descobriments psicofísics i dades neurofísiques. Determinem les correctes adaptacions no lineals necessàries per als nostres resultats de mapeig tonal per tal d'obtenir l'aparença òptima en diferents condicions de visualització, a través d'experiments psicofísics i desenvolupar un mètode automàtic per poder predir dades experimentals. El nostre TMO produeix resultats d'aspecte natural, sense cap tipus d'artefactes espacials o temporals. Els tests de preferència dels usuaris mostren que el nostre mètode obté millors resultats en comparació amb les tècniques més recents. El TMO és ràpid i podria ser implementat en el hardware de la càmera. Pot ser utilitzat per al monitoratge de càmeres HDR en pantalles regulars, com a substitut de la correcció gamma, i com una manera de proporcionar al colorista amb contingut que té alhora un aspecte natural i una aparença nítida i clara.High Dynamic Range (HDR) imaging techniques potentially allow for the capture and storage of the full information of light in a scene. However, common display devices are limited in terms of their contrast and brightness capabilities, thus HDR images must be tone mapped before presentation on a display device to ensure that the original appearance of the scene is reproduced. In this thesis, we take two approaches to the tone mapping problem. First, we develop a general framework for improving any tone mapped image by reducing the distance with the corresponding HDR image in terms of a non-local perceptual metric. The distance is minimized by means of a gradient descent algorithm. Second, we develop a real-time Tone Mapping Operator (TMO) that is well suited to the statistics of natural scenes, and is in keeping with new psychophysical findings and neurophysical data. We determine the adequate non-linear adjustments needed for our tone mapping results to look best in different viewing conditions through a psychophysical experiment and develop an automatic method that can predict the experimental data. Our TMO produces results that look natural, without any spatio-temporal artifacts. User preference tests show that our method outperforms state of the art approaches. The TMO is fast and could be implemented on camera hardware. It can be used for on-set monitoring of HDR cameras on regular displays, as a substitute for gamma correction, and as a way of providing the colorist with content that is both natural looking and has a crisp and clear appearance.

Full textAbstract:
Clothing can influence heat stress depending on the design and its ability to act as a barrier. The progressive heat stress protocol permitted the collection of data to empirically estimate the apparent total evaporative resistance (Re,T,a). Five different clothing ensembles were evaluated, which included work clothes, cotton coveralls, and three limited-use protective clothing ensembles including a pthesis-barrier ensemble, (Tyvek® 1424), water-barrier, vapor-permeable ensemble (NexGen® LS 417), and a vapor-barrier ensemble (Tychem QC®). The study design called for three metabolic level's: low, moderate, and high (L, M, & H) and three heat stages: compensable, transitional, uncompensable (C, T, U). The purpose of this study was to determine if Re,T,a values remained constant over a range of metabolic and heat stage levels. Calculated Re,T,a values were compared using a four-way mixed model analysis of variance. Significant differences for Re,T,a were found among ensembles, metabolic levels, heat stress stages, as well as interactions among ensembles and metabolic levels along with ensembles and heat stress stages (p < 0.0001). A Tukey's Honestly Significant Difference multiple comparison test identified where significant differences occurred (p < 0.05). Results show Re,T,a values differ over a range of metabolic levels and stages of heat stress. Additionally, convection is more supportive of evaporative cooling than diffusion.

Full textAbstract:
Total Hip Arthroplasty (THA) is a successful technique restoring lost mobility to patients suffering from osteoarthritis. A successful THA normalises the biomechanics of the hip joint so that a patient can achieve the required range of motion to fulfil their daily activities. A recent development in THA implant technologies has been the introduction of femoral neck modularity. Assessment of femoral neck modularity has been limited by two factors. Firstly, range of motion requirement is not well understood and secondly previous clinical reports have lacked a comparison against an established successful THA implant. This study has successfully addressed these limiting factors by developing an innovative range of motion benchmark which considers the activities a person is required to undertake during their daily routine. The benchmark was developed using a systematic review of the literature focussing on hip joint biomechanics. This has been the first study to provide a clinically meaningful representation of hip joint range of motion which permits operative outcome to be directly compared against an established benchmark. Integration of the range of motion benchmark within the surgical environment was achieved by using a surgical navigation measurement device. Intra-operative measurement meant that post-operative range of motion could be simulated and compared against the requirement set by the range of motion benchmark. Distinct outcome measures have been able to be developed using this comparison which has allowed the surgical process to be assessed like a manufacturing system. Using these outcome measures, it was found that femoral neck modularity has greater potential to adjust implant orientation in comparison to non-modular femoral neck implants to achieve the ideal range of motion. However, this potential is being limited due to the current modular neck options available and because of difficulty experienced by the surgeon in assessing implant orientation. These findings have been used to develop a medical device which provides guidance to the surgeon about the THA implant orientation and thus allow them to able to make the correct modular neck choice to maximise range of motion and improve the operative outcome for the patient.

Owen, Lewis Robert. "The analysis of local structural effects in alloys using total scattering and reverse Monte Carlo techniques." Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/273748.
Full textAbstract:
Over the years `short-range order' (SRO), whereby the local atomic arrangement differs from that of a random distribution, has been used to explain physical phenomena such as thermodynamic discontinuities, increased strength, anomalous electrical resistivity and magnetic variations in a host of alloys. However, due mainly to experimental difficulties and the complexity of the calculations required for the analysis of diffuse scattering, such work has been largely abandoned and hence quantification and assessment of SRO is notably sparse in the literature. The recent development of reverse Monte-Carlo (RMC) methods for the analysis of total scattering data has opened a promising route for the assessment of a material's local environment and has already provided important insights into a host of complex chemical systems, including liquids, network glasses, nano-materials, functional oxides and metal organic frameworks. The work presented in this thesis focuses on the development of a new methodology for the analysis of local structural effects in metallic systems using total scattering, and the first systematic application to the study of alloys. The simulation of total scattering data from a range of model structures is used to show that the information content of total scattering functions, in particular the pair distribution function (PDF), is sufficiently high to allow the assessment of different types and degrees of short-range order. This is supported by a demonstration of how such orders can be quantified from large box models, produced by fitting total scattering data using the RMC algorithm, with the mathematical analyses outlined. This culminates in a proposed methodology for the analysis of SRO in alloys. Having developed this analytical methodology it is subsequently applied to a number of interesting alloy systems. To demonstrate the efficacy of this methodology it was first applied to the study of a sample of Cu$_{3}$Au - the classically cited case example of a system demonstrating SRO prior to an ordering transition. This experiment provides new insight into this well characterised transition, and also demonstrates the significance of data processing errors on the generation of artefacts in large box modelling. The technique is also applied to the study of the industrially important family of nickel superalloys, assessing ordering in the gamma-phase alloy Ni-Cr and the sublattice orderings occurring in L1$_{2}$ alloys. Next, the use of the technique for the analysis of local strains exhibited in a lattice is presented. A series of models is used to demonstrate how the PDF is expected to change under variations in local strain caused by increased concentration of atomic substitution and variation in atomic radii. This is subsequently used to study the characteristic high-entropy alloy (HEA) CrMnFeCoNi. Through analysis of the PDF, it is demonstrated that the level of local strain exhibited in this alloy is not significantly different from those of other related compositionally simpler alloys. This result is highly significant as it challenges one of the core principles of the field - that the lattices of HEAs are necessarily highly strained. Finally, the energetics of ordering reactions are briefly considered and used to justify some of the observed transformations presented in the earlier work. Together, the body of work in this thesis shows how the total scattering technique can be used to provide valuable insight into a host of interesting local phenomena occurring in alloy systems. It is hoped that this will open up a new field of study into these effects, and ultimately guide the creation of new alloys based on these structure-property relationships.

Full textAbstract:
Lumbar spine range of motion (ROM) is conventionally measured using multiple, individual anatomical plane movements. This is unwieldy for clinical research, because it relies on the assumption that a large proportion of subjects will present with the same impairment. The objective of this thesis work, therefore, was to assess the reliability of a novel measure of total lumbar spine ROM, to be used in future studies. We hypothesized that the reliability of this measure would be ≥0.9, so as to meet previously suggested criteria for monitoring individual patient progress. Twenty subjects with chronic low back pain (LBP) were recruited for two testing sessions. At each session, subjects performed 3 series of 8 end-range, randomly ordered lumbar spine movements, at 45 degrees intervals around the full circle, with the help of visual feedback. Lumbar spine motion was acquired using two, 6-degrees-of-freedom electromagnetic motion capture sensors placed on the skin over the spinous processes of the twelfth thoracic (T12) and first sacral (S1) vertebrae. The measure of interest was based on the relative position of T12 in the transverse plane of S1. Two curve fitting approaches - least-squares ellipse and cubic spline - were used to fit a shape to the 8 end-positions of movement in each series. The area of this shape was used to provide a measure of the total ROM, and the centre point to provide a measure of movement distribution and symmetry. Generalizability theory was used to assess the reliability of the area of each shape, and of its centre point in the anterior-posterior and medio-lateral axes of the transverse plane of S1. The index of dependability for the total lumbar spine ROM (area) was excellent (0.94 - 0.95), and moderate-to-excellent (0.59 – 0.91) for its distribution (centre points), with slightly better values achieved with the spline-fitting approach. Analysis of extrapolated data also indicated that similar values would be achieved using 3 repetitions of the task in a single testing session. These results support the use of this novel measure of total lumbar spine ROM in future clinical studies.L'amplitude des mouvements de la colonne lombaire (ou ROM, pour range of motion en anglais) est traditionnellement mesurée à l'aide de multiples mouvements individuels exécutés sur les plans anatomiques. La technique utilisée pour obtenir cette mesure complique la recherche clinique, car elle repose sur l'hypothèse qu'une forte proportion de sujets présente la même déficience. L'objectif de cette thèse était donc d'évaluer la fiabilité d'une nouvelle mesure de mouvement global de la colonne lombaire, qui serait utilisée dans des études futures. Notre étude repose sur l'hypothèse que la fiabilité de cette mesure serait ≥ 0,9; de manière à répondre à des critères préalablement proposés pour suivre les progrès d'un patient unique.Vingt sujets souffrant d'une lombalgie chronique (ou LBP, pour low back pain en anglais) ont été recrutés pour deux séances. À chaque séance, les sujets, aidés d'une rétroaction visuelle, ont effectué 3 séries de 8 mouvements de fin d'étendue de colonne lombaire, à 45 degrés d'intervalle autour d'un cercle complet, et ce, dans un ordre aléatoire. Les mouvements de la colonne lombaire ont été obtenus au moyen de deux capteurs électromagnétiques à 6 degrés de liberté, placés sur la peau au-dessus des apophyses épineuses de la douzième vertèbre thoracique (T12) et de la première vertèbre sacrée (S1). La mesure qui nous intéresse a été calculée d'après la position relative de T12 dans le plan transversal de S1. Deux méthodes d'ajustement de courbe ont été utilisées pour lier les 8 points de fin de mouvement dans chaque série : l'ellipse par les moindres carrés et la fonction spline cubique. L'aire de la forme ainsi obtenue a servi à fournir une mesure de la ROM totale; et le point central, une mesure de la distribution et de la symétrie des mouvements. La théorie de la généralisabilité (en anglais Generalizability Theory) a été employée pour évaluer la fiabilité de l'aire de chaque forme et celle de son point central dans les axes antéro-postérieur et médio-latéral du plan transversal de S1. L'indice de fiabilité était excellent (0,94 – 0,95) pour la ROM globale de la colonne lombaire (l'aire) et allait de modéré à excellent (0,59 à 0,91) pour la distribution des mouvements (points centraux), avec des valeurs légèrement plus élevées pour la méthode d'ajustement par spline. L'analyse des données extrapolées a également indiqué que des valeurs similaires seraient obtenues en utilisant 3 répétitions de la tâche dans une séance unique. Ces résultats appuient l'utilisation de cette nouvelle mesure de la ROM de la colonne lombaire dans de futures études cliniques.

Full textAbstract:
Failure to maintain thermal equilibrium can cause uncontrollable increases in body core temperature beyond critical upper limits. In selecting clothing, consideration must be given to the heat transfer properties of clothing that may restrict the cooling capacity of the human body under heat stress conditions, most importantly, apparent total evaporative resistance (Re,T,a). This study calculated and compared Re,T,a for five clothing ensembles under varying heat stress conditions, including three relative humidity (RH) levels and three stages of heat stress to determine if Re,T,a values varied or remained the same with changes in heat stress conditions. A four-way mixed model analysis of variance demonstrated significant differences for estimated Re,T,a values among ensembles, RH levels, heat stress stages, and interactions among ensembles and RH levels and ensembles and heat stress stages (p < 0.0001). No significant interaction among RH levels and heat stress stages was found (p = 0.67). A Tukey's Honestly Significant Difference multiple comparison test was used to identify where significant differences occurred (p < 0.05). The results of the study indicated that Re,T,a values do change with RH levels and stages of heat stress and that the theoretical framework for explaining heat-exchange in hot environments is not yet well-established. Also confirmed was the dominance of the convection pathway over the diffusion pathway in hot environments.

"Relación entre el tono medio hablado y el rango tonal cantado en un grupo de cantantes populares." Tesis, Universidad de Chile, 2012. http://www.repositorio.uchile.cl/handle/2250/115641.
Full textAbstract:
El objetivo de este estudio es establecer la posible relación existente entre el tono medio hablado (TMH) y la tesitura en cantantes populares de Santiago de Chile.
Participaron en esta investigación 32 sujetos con los siguientes requisitos: Todos eran cantantes populares, profesionales o aficionados, hombres o mujeres, residentes en la ciudad de Santiago, cuyas edades fluctúan entre los 18 y 40 años, con una demanda vocal semanal mínima de 5 horas. Uno de los criterios de selección fue la ausencia de disfonía. La elección de los sujetos fue por conveniencia.
Se hizo anamnesis de antecedentes personales, mórbidos y vocales a través de la FICHA FONOAUDIOLÓGICA DE EVALUACIÓN VOCAL ADAPTADA y se realizó un análisis acústico de la calidad vocal a través del programa MDVP para descartar disfonía.
Para la obtención del TMH, se grabó y analizó la lectura del texto “El abuelo”, utilizando el programa Multi Speech. Además se obtuvo el TMH perceptualmente utilizando como apoyo un teclado. Los límites inferior y superior de la tesitura se obtuvieron a través de vocalizaciones con apoyo del teclado. Los resultados se analizaron de forma descriptiva, a través de tablas de frecuencia y porcentaje.
Se encontró una correlación positiva relativamente baja entre voz hablada y cantada en todos los sujetos (48,14%), siendo esta menor en hombres que en mujeres. Se vio que en las clasificaciones medias (Mezzosoprano-barítono) esta correlación era menor que en clasificaciones extremas. Es importante señalar que no se encontraron bajos en este estudio. El comportamiento vocal heterogéneo encontrado dentro del grupo de estudio hace pensar que es probable que dentro del canto popular no haya una relación entre voz cantada y hablada. Sin embargo, es necesario investigar en mayor profundidad el tema a futuro.The object of this investigation was to determine the possible existing relationship between the Mean Spoken Tone (MST) and the range of tones of the singing voice, in popular singers in Santiago of Chile. 32 people participated in this investigation. They had the following requirements: They were all popular singers, professional and amateur, male and female, living in Santiago, whose ages ranged from 18 to 40, with a minimum vocal demand of 5 hours per week. The selection of these subjects was made based on convenience. We conducted an anamnesis to collect personal, morbid and vocal history of the subjects, using the ADAPTED VOCAL EVALUATION CHART. An acoustic analysis was made using the MDVP program, to discard dysphonia. To obtain the MST, we recorded and analyzed the reading of the text “The Grandparent”, using the Multi Speech program. It was also obtained perceptually using a keyboard to support the analysis. The range of singing tones was obtained through vocalizations again using a keyboard as support. The results were analyzed descriptively, through frequency charts and percentages. We found a relatively low degree of positive relationship between spoken and singing voice through all of the subjects (48.14%), though this relationship was significantly higher in women than in men. In middle classifications (Mezzosoprano-baritone) this relation was lower than in the rest of the classifications. It’s important to mention that there were no Bass participating in this study. The heterogeneous vocal behavior found within this group suggests that there may be no relation between singing and spoken voice in popular singers. However, it is necessary to further investigate this issue in the future.

O objetivo deste estudo foi comparar as adaptações neuromusculares e morfológicas de treinamentos de força realizados com amplitudes parcial e total de movimento nos músculos flexores de cotovelo e extensores de joelho. Participaram do estudo 41 voluntários do sexo masculino destreinados em força (23,78 ± 3,27 anos), divididos em três grupos: PS-TI (Parcial Superior – Total Inferior; n=14), TS-PI (Total Superior – Parcial Inferior; n=16) e GC (Grupo Controle; n=11). O grupo PS-TI realizou o treinamento de flexão de cotovelo em amplitude parcial (40°- 90°) e de extensão de joelho em amplitude total (90° - 0°). O grupo TS-PI realizou o treinamento de flexão de cotovelo em amplitude total (0° - 120°) e de extensão de joelho em amplitude parcial (60° - 30°). Os sujeitos treinaram duas vezes por semana por um período de 12 semanas. O GC não realizou o treinamento. Antes e após o período de treinamento, os sujeitos foram avaliados em parâmetros relacionados à força muscular dinâmica, resistência muscular, pico de torque isocinético, pico de torque isométrico em diferentes ângulos, ativação muscular dinâmica e isométrica em diferentes ângulos e hipertrofia muscular. Para a força muscular dinâmica, avaliada pelo teste de uma repetição máxima (1RM), o grupo TS-PI teve incrementos de 1RM de flexão de cotovelo (29,37%) maiores que PS-TI (18,42%) (p<0,001). Ainda, o grupo PS-TI teve incrementos de 1RM de extensão de joelho (25,69%) maiores que TS-PI (15,06%) (p=0,038). A resistência muscular, avaliada pelo teste de 60% de 1RM absoluto, mostrou, para a flexão de cotovelo e extensão de joelho, que o grupo que treinou em amplitude total realizou um número maior de repetições do que o que treinou em amplitude parcial o exercício avaliado. Não foram encontradas diferenças nos incrementos de picos de torque isocinético e isométrico em diferentes ângulos entre os grupos PS-TI e TS-PI na flexão de cotovelo e extensão de joelho. Não foram encontrados incrementos significativos de ativação muscular, avaliada durante os testes isocinéticos e isométricos em diferentes ângulos. Foram encontrados incrementos significativos de hipertrofia, avaliada pela espessura muscular, nos músculos flexores de cotovelo, sem diferença entre os grupos PS-TI e TS-PI. Quanto à espessura muscular nos extensores de joelho, o grupo PS-TI teve maiores incrementos quando comparado a TS-PI no somatório de todos os músculos extensores de joelho (6,74% vs. 5,02%) (p=0,001) e no somatório de três diferentes pontos avaliados no músculo vasto lateral (5,20% vs 3,37%) (p=0,033). Assim, todas as diferenças encontradas neste estudo foram a favor do treinamento em amplitude total de movimento, ainda que o grupo que treinou o exercício em amplitude parcial de movimento tenha treinado com cargas significativamente mais elevadas durante todo período de treinamento (PS-TI: 47,94% mais elevada na flexão de cotovelo; TS-PI: 61,32% mais elevada na extensão de joelho). Dessa forma, pode-se concluir que o treinamento de força em amplitude total de movimento causa melhores adaptações neuromusculares e morfológicas, sendo mais efetivo para incrementos de força, resistência e hipertrofia muscular de flexores de cotovelo e extensores de joelho em homens jovens.The purpose of this investigation was to compare neural and morphological adaptations of a partial range of motion versus a full range of motion strength training in the elbow flexors and knee extensors. Forty-one untrained men (23.78 ± 3.27 years) were divided into three groups: PU-FL (Partial Upper – Full Lower; n=14), FU-PL (Full Upper – Partial Lower; n=16) and CG (Control Group; n=11). The PU-FL group during the training performed elbow flexion with partial range of motion (40° - 90°) and performed knee extension with full range of motion (90° - 0°). The FU-PL group during the training performed elbow flexion with full range of motion (0° - 120°) and performed knee extensor with partial range of motion (60° - 30°). The subjects trained two times per week during 12 weeks. The CG did not train. Before and after training period, subjects were evaluated in parameters related to dynamic muscle strength, muscle endurance, isokinetic peak torque, isometric peak torque at different angles, dynamic and isometric (at different angles) muscle activation and muscle hypertrophy. For the dynamic muscle strength, evaluated by one repetition maximum (1RM) test, the increase in 1RM of the elbow flexion for the FU-PL group (29.37%) was greater than PU-FL group (18.42%) (p<0.001). Moreover, the increase in 1RM of the knee extension for the PU-FL group (25.69%) was greater than FU-PL (15.06%) (p=0.038). The muscle endurance, evaluated by 60% of 1RM test with absolute load in the elbow flexion and knee extension, showed the group that trained the exercise with full range of motion performed a greater number of repetitions than those trained the evaluated exercise with partial range of motion. No differences were observed between PU-FL and FU-PL groups for the increase for isokinetic or isometrics, at different angles, peaks torque in elbow flexion and knee extension. No significant findings were observed for muscle activation measured during isokinetic and isometrics tests. There were significant increases on muscle hypertrophy, evaluated by muscle thickness, of the elbow flexors, but no difference were observed between PU-FL and FU-PL groups. For the muscle thickness of the knee extensors, the increase for the PU-FL group was greater than FU-PL group at sum of all knee extensors muscles (6.74% vs. 5.02%) (p=0.001) and at sum of three different points evaluated in the vastus lateralis muscle (5.20% vs. 3.37%) (p=0.033). Thereby, all the differences found in this investigation were in favor of full range of motion training, despite the group that trained with partial range of motion have been used higher loads throughout the training period (PU-FL: 47.94% higher in elbow flexion; FU-PL: 61.32% higher in knee extension). Thus, we can conclude that strength training with full range of motion causes better neural and morphological adaptations, being more effective for increase in strength, endurance and muscle hypertrophy in the elbow flexors and knee extensors of the young men.

Full textAbstract:
Introduction: Knee osteoarthritis is one of the common causes leading to musculoskeletal disability of the elderly around the world. Total knee replacement (TKR) is an effective and common treatment for end stage knee arthritis. Most papers suggest that early rehabilitation could improve postoperative knee function. However, postoperative pain and local swelling are the complications that diminish range of motion (ROM) and inhibit patients’ recovery. A comprehensive review of the literature reveals that cryotherapy is an effective and safe method to overcome these complications. In this paper, a guideline of using cryotherapy in reducing postoperative pain and knee swelling so as to improve the ROM of patients and promote recovery after TKR has been developed.
Objectives: The objectives of this translational research are: (1) to look for relevant papers that related to cryotherapy in reducing postoperative pain and knee swelling so as to improve the ROM of patients after TKR; (2) to gather and criticize the data obtained; (3) to develop a guideline of using cryotherapy in reducing pain, knee swelling and improving ROM of patients after TKR based on the evidence from the reviewed literature; (4) to assess the implementation potential of the newly developed guidelines; and (5) to establish the implementation and evaluation plans for the new innovation.
Methods: An empirical literature search published from 2001 to 2011 by several searching engines regarding cryotherapy in reducing postoperative pain and knee swelling with the aim to improve the ROM of patients after TKR has been conducted. After that, the qualities of relevant studies were retrieved and criticized by using the appraisal checklist of the SIGN (2004). The derived evidences were then be summarized and synthesized. An evidence-based guideline was established with reference to the evidence from the reviewed literatures and the results of the quality assessment. Recommendations are graded by SIGN (2004). The implementation potential including transferability, feasibility and cost-benefit ratio of the innovation were assessed as well. Lastly, implementation and evaluation plans have been developed to assess and appraise the effectiveness of the new guideline.
Results: Finally, seven studies were chosen as final references after methodological quality assessment. Four main types of comparison were made from these seven reviews including: (1) continuous compressive cryotherapy vs. compressive crepe bandage; (2) comparison in different temperature of cryotherapy; (3) outcome measures; and (4) complications in cryotherapy. After the summary, six main categories of recommendations were synthesized: (1) continuous compression cryotherapy; (2) effective temperature; (3) potential complications; (4) regular assessment; (5) duration; and (6) intermitted ice pack regimen. Based on these syntheses and recommendations, a guideline of using cryotherapy for patients after having TKR was developed.
Conclusion: With the implementation of the newly developed evidence-based cryotherapy guidelines for patients after having TKR in local clinical settings, the improvement in the ROM of the knee joint will be anticipated as a result of the reduction in postoperative pain and knee swelling.published_or_final_version

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, NevadaThe Air Force SEEK EAGLE Office (AFSEO) was chartered by the Secretary of the Air Force in December 1987. The mission of the AFSEO is to provide the United States Air Force increased combat capability through central management of the aircraft-stores certification process and provide in-house engineering and operations research capabilities. Additionally, the AFSEO is required to ensure the future viability of the aircraft-stores organic in-house capability with the insertion of evolving technologies. To accomplish this mission, the AFSEO employs all phases of the test process; from Digital Model and Simulation (DMS) to Open Air Range (OAR) flight tests. The AFSEO desires to prepare for the future DoD environment, and minimize the cost of developing its products that require advanced sensors and telemetry capability. For a number of years, a mainstay in the process has been instrumented aircraft. These aircraft were specially instrumented to support the mission of AFSEO. Similarly, stores were instrumented to obtain environmental data such as loads and vibration. With the rising cost of instrumentation and the national DoD trend to reduce the cost of development and maintenance of instrumentation, a new method will need to be found. Several advanced concepts in ground and airborne instrumentation at Eglin AFB are needed to support the mission of the AFSEO. These include a new generation of telemetry devices, sensors, and data acquisition components to provide rapid and cost effective instrumentation of test aircraft, stores, and suspension equipment. The new generation telemetry will provide integrated circuitry with “peel and stick” subminiature telemetry sensors. These telemetry sensors will provide flutter and structural loads data for aircraft-stores combinations. In conjunction with the telemetry sensors, advanced aircraft platform instrumentation will be needed to match precision flight mechanics to the spatial telemetry measurements for stress, strain, and dynamic activity of stores.

La geomatica è la disciplina che si occupa di acquisire, modellizzare, interpretare, elaborare, archiviare e divulgare informazioni georeferenziate, ovvero informazioni caratterizzate da una posizione in un prescelto sistema di riferimento.
La geomatica ha i suoi fondamenti metodologici nelle discipline che si sono occupate di risolvere i problemi di posizionamento sulla superficie terrestre e nelle sue immediate vicinanze (geodesia, astronomia, matematica, statistica).
Alla geomatica afferiscono pertanto le tecniche di posizionamento terrestri (storicamente ricomprese nella topografia) e spaziali (GPS), la fotogrammetria digitale, le tecniche di scansione laser da terra e da velivolo, il telerilevamento da aereo e da satellite, la cartografia numerica, la geostatica.
Applicare la geomatica in ambito forense significa descrivere le metodologie e le tecniche che vengono utilizzate in presenza di indagini giudiziarie, quali ricostruzioni di scene del crimine o ricostruzioni di incidenti stradali a partire proprio da rilievi geomatici.
Le argomentazioni della tesi si suddividono in tre parti. La prima in cui descrivo le principali tecniche di misura e strumenti utilizzati dalla geomatica in ambito forense; la seconda e la terza parte descrivono in particolare le metodologie e le tecniche che un perito forense può applicare in presenza di due contesti abbastanza frequenti: la ricostruzione di scene del crimine e la ricostruzione di incidenti stradali.

Full textAbstract:
Les bus électriques à batterie (BEB) représentent une solution prometteuse pour remplacer les flottes de bus diesel actuelles consommant des énergies fossiles grâce à leur efficacité énergétique élevée et à leur potentiel de réduction des émissions de gaz à effet de serre et à l’absence d’émissions de polluants atmosphériques locaux. Cependant, cette technologie doit faire face à plusieurs défis, en particulier le coût total de possession (TCO) élevé et des contraintes opérationnelles comme l’autonomie des bus, le temps et le lieu de recharge. Cette thèse présente une méthodologie systématique qui vise à développer des solutions pour surmonter ces défis en fournissant un dimensionnement des batteries et une stratégie de recharge optimales pour les BEB. D'abord, un modèle énergétique multi-physique de bus est développé pour évaluer ses besoins énergétiques en prenant en considération ses différents systèmes énergétiques. Ensuite, la consommation d'énergie du bus est évaluée dans plusieurs conditions de fonctionnement afin de quantifier sa consommation d'énergie réelle. Un modèle techno-économique d'une ligne de bus est développé afin d'évaluer l'impact des différentes stratégies de dimensionnement et de recharge des batteries sur les coûts et le fonctionnement du BEB. Ensuite, un modèle TCO est introduit en tenant compte les coûts unitaires BEB, les coûts d'achat et de remplacement des batteries, les coûts d'électricité, les coûts d'infrastructure et de maintenance. L'analyse des résultats d’un cas d’étude à Paris souligne les compromis entre le TCO et les perturbations et les retards des horaires du BEB en fonction des différentes tailles de batterie et stratégies de recharge. Enfin, une méthodologie minimisant le TCO est proposée en déterminant un dimensionnement des batteries et une stratégie de recharge optimales pour la flotte de BEB tout en garantissant l'absence de perturbation des horaires ou des interruptions du service. Elle repose sur une optimisation en deux étapes qui utilise à la fois la programmation dynamique et un algorithme génétique. Les résultats montrent que la méthodologie proposée pourrait réduire le TCO du BEB entre 15-25% par rapport aux approches actuellement adoptéesInitiatives to decrease emissions from the transport sector are increasing worldwide by seeking alternative technologies to replace oil-based mobility. Battery Electric Buses (BEB) present a promising solution thanks to their high energy efficiency, low greenhouse gas emissions and the absence of local pollutant emissions. However, this technology still faces many challenges, especially its high total cost of ownership (TCO) and other operational factors such as the limited bus driving range, the high energy refueling time, and the required charging technologies and strategies. In this context, this thesis presents a systematic methodology that aims at developing solutions to help overcoming these challenges by providing optimal battery sizing and charging strategy for BEB. First, a comprehensive multi-physical bus energy model is developed to evaluate its energy needs considering all the energy systems encountered within. The energy consumption of the bus is then evaluated at a variety of operating conditions. Then, a techno-economic model of an entire bus line is developed in order to assess the impact of different battery sizing and charging strategies on the costs and operation of BEB. A TCO model is introduced considering the BEB unit costs, battery purchase and replacement costs, energy and power costs, infrastructure, and maintenance costs. A case study in Paris city is presented and the analysis reveals the resulting tradeoff between the TCO and BEB schedule disruptions and delays as function of different battery sizes and charging strategies. A methodology to minimize the TCO of BEB deployment is presented providing the optimal battery sizing and charging strategy for BEB, while respecting the BEB operation constraints. The methodology is a 2-step optimization algorithm that utilizes both Dynamic programming and Genetic Algorithm optimization routines. The results show that the proposed methodology could reduce the BEB TCO between 15-25% compared to the currently adopted approaches to deploy BEB

La méthode proposée consiste à connecter les convertisseurs DAC et ADC dans le domaine analogique pour n'avoir besoin que d'instruments de test numériques pour générer et capturer les signaux de test. Un algorithme de traitement du signal a été développé pour discriminer les erreurs des DACs et ADCs.

In my thesis, I focused on monitoring of microorganisms in the sample of red grape juice and on the interactions between yeasts, bacteria and filamentous fungi. Three different media were applied for the cultivation of microorganisms; firstly for monitoring of total volume of microorganisms, secondly for yeasts and third time for lactic acid bacteria. The indirect method was used for the determination of the amount of viable cells. This method consists in enumerating of visible macroscopic colonies grown up on agar plates. When the cells grew up, the forms of colonies were analyzed visually and the morphology of microorganisms was detected microscopically. The operating time of enzymes in grape juice in the production of red wine was monitored after application of commercial enzymatic preparation. The enzym action in grape juice was observed on the basis of the process of degradation of high – molecular substrate by enzymes through the use of Ubbelohd´s viscometer. The research findings provided a lot of knowledge about the occurance of microflora in the process of production of red wine. The commercial preparations added to grape juice played a significant role.

Tone is the sharp transition of frequency, amplitude, and duration of the vibration of vocal folds within 150 to 300 millisecond. The process is accomplished by stretching and contraction of laryngeal muscles. Exercises on laryngeal muscles enhances its strength and endurance, coordination among respiratory, phonation, and resonance sub-systems, and overall physiological function of voice by expanding one’s speaking physiological frequency range. Tone transition suggests a mechanism similar to that of physiological voice therapy. If tonality in Mandarin is viewed as a daily vocal manipulation in pitch and loudness, it may enhance their physiological frequency range. It is clinically significant to probe into whether the existence of tonality can improve vocal function. Therefore, prior research focusing on tonality and physiological frequency range is needed, as well as discussion on the relationship between various physique and corresponding voice measures. The purposes of this study are (1) to compare the physiological frequency and intensity ranges of tonal and non-tonal language female speakers, and (2) to compare the oral pressure and phonation threshold pressure (PTP) of tonal and non-tonal language female speakers. A total 24 female participants will be recruited in the study (aged 20-40 years). There are 12 female tonal language speakers and 12 non-tonal speakers. The study is set to compare physiological performance between tonal and non-tonal language speakers by analyzing their voice range profile and aerodynamic measures. For data analysis, an independent-samples t-test and Mann-Whitney U test are used to compare vocal measures between two speaking groups. In voice range profile frequency measurements, the results revealed that tonal language female speakers had significantly greater lowest frequency, highest frequency and maximum physiological frequency range of phonation (MPFR) than non-tonal speakers. In voice range profile intensity measurements, the average loud voice, loudest voice, average soft voice, softest voice, maximum dynamic intensity range (MDIR) and average dynamic iii intensity range (MDIR) for tonal and non-tonal speakers are no significant difference. In aerodynamic measurements, tonal language female speakers had significantly lower oral pressure and phonation threshold pressure (PTP). The identification of differences in the maximum physiological frequency range of phonation, oral pressure and phonation threshold pressure between tonal and non-tonal language speakers allow us to determine the frequency and intensity effects on maximum vocal performances which could be the result of the particular types of vocal exercise associated with tonal language.The tone of tonal language appears to provide good example of a therapeutic strategy to expand the frequency range.

Objective: To investigate and better understand the influence of Anterior Cervical Discectomy and Fusion surgery on cervical kinematics and to elucidate possible relationships between cervical morphometrics and altered cervical biomechanics. Introduction: Anterior Cervical Decompression and Fusion (ACDF) is one of the most commonly employed surgical techniques to treat Cervical Spondylotic Myelopathy (CSM). Despite the reported high clinical success rates of ACDF, an increased rate of adjacent segment disease (ASD) post ACDF surgery has raised some significant concerns in the literature. Many demographical factors such as gender, age and duration of symptoms have all been implicated to contribute to the development of ASD, however, limited studies have specifically attempted to quantify the relationship between over-compensatory adjacent segmental contribution to total cervical Range of Motion (ROM) and the development of ASD. Given the likely alternation of the cervical biomechanics due to the immobilization of a segment following ACDF, a better understanding of the postoperative kinematical change is well warranted. Moreover, no study has conducted a morphometric analysis of the cervical vertebral column and its influence on the global and segmental ROM in the literature to date. Based on the immanent biomechanical relationship between vertebral morphology and resultant spinal kinematics, a better understanding of the potential influence using an in-vivo, prospective design is needed to fulfill this gap in our knowledge. Materials and methods: Forty-seven patients with clinically diagnosed CSM undergoing either a single- or two-level ACDF were recruited in the study. Neutral, full active flexion and extension lateral radiographs were taken preoperatively and then at 3, 6 and 12 month follow-ups for all patients. Using the obtained radiographs, global ROM of C2-7, ROM of the treated functional spinal unit (FSU) as well as the superior and inferior segmental ROM were obtained using a computer based quantitative measurement analysis software. The relative contribution from the FSU and each of the adjacent segments to total cervical ROM were compared pre- and post-operatively. MRI scans conducted as part of the preoperative workup were also obtained in order to accurately determine the vertebral morphometric measurements, which included vertebral length, vertebral height, and disc height. In order to investigate and simulate the cervical biomechanical properties during the movement, a number of parametric finite element models (FEM) were also constructed based on patients’ radiographs with the observed ROM inputted as the individual loading conditions. Statistically, a mixed design repeated ANOVA analysis was used to determine the interaction and main effects of surgery type (single or two-level) and time (pre-, 3, 6, 12 month). A univariate linear regression analysis was then conducted to determine the relationship between morphological factors and the kinematical changes. Results Overall, 30 single-level and 17 two-level ACDF patients were recruited. The patients consisted of 28 males and 19 females with a mean age of 55.4 (range 30 to 79) years. Single-cage patients demonstrated a significantly decreased total ROM at 3 months (p=0.002) but improved to pre-operative level by 6 months. In contrast, patients with two-cage ACDF demonstrated significantly decreased total ROM at all follow up assessments (p<0.02) and did not reach pre-surgery level even at 12 months post-surgery. Similar trend was observed for the FSU ROM where a significantly decreased contribution was found for the single-cage patients at all follow up assessments (p<0.01), however, the FSU contribution was only significantly decreased at 12 months (p=0.047) for the two-cage patients. In terms of upper adjacent ROM contribution, it was found to be significantly increased at all follow up assessment points (p<0.05) for the single-cage patients but was only significantly increased at 6 months (p=0.042) for the two-cage patients when compared to pre-surgery. However, in terms of the raw contribution, it was noted that the two-cage patients demonstrated a 10-15% more in contribution to the total ROM when compared to the single-cage at the upper adjacent segments. No significant changes were found for both groups for the lower adjacent ROM contribution. For the correlation of morphological factors and cervical kinematical change, in patients with two-cages, the posterior disc height of the FSU’s upper segment was found to have a strong (R=-0.717) and significant (p=0.03) negative correlation with an increased upper adjacent segmental contribution to total ROM. This was not the case for single-cage patients. No other morphological factors were found to have a significant correlation with the post-operative kinematical changes. The FEM modeling illustrated that based on the obtained radiographs, the two-cage patients demonstrated a greater increase in upper adjacent intradiscal pressure (IDP) than the single-cage patients for both flexion (44% vs 20%) and extension (34% vs 23%) respectively. Conclusion: Single-cage patients regained their pre-operative total ROM by 6 months post-surgery and the fused segment demonstrated adequate fusion and immobility by 3 months. The results indicated that the regained total ROM were mostly due to a slight increase in the upper adjacent segment contribution at 3 months, which then remained unchanged throughout the study period. In contrast, due to the increased levels of fusion in the two-cage patients, the fused segment did not demonstrate adequate immobilization until 6 to 12 month post-surgery. Furthermore, patients with two-cages demonstrated a significant increase of upper segment contribution at 6 months and coupled with greater likelihood of an increase in IDP based on the FEM analysis. Lastly but not the least, the upper posterior disc height of the FSU was found to have an association with the increased upper adjacent segment contribution in patients with two-cages.

Background and Purpose: Postoperative exercise rehabilitation is important for patients to recover and regain joint function after total hip arthroplasty. The key feature of this rehabilitation treatment is to strengthen the surrounding muscles of the replaced hip joint. For patients with total hip arthroplasty who consider the cost of professionally supervised exercise programs and facility provision, it is imperative to develop and test home-based self-monitored exercise programs. The purpose of this study was to investigate the efficacy of a home-based resistance band exercise program on lower limb muscle strength, dynamic balance, functional exercise capacity, hip function, hip range of motion, and health-related quality of life in patients with total hip arthroplasty. Methods: This study is an experimental design with repeated measures. A convenience sample of 94 osteoarthritis patients undergoing primary total hip replacement surgeries were recruited from orthopedic words of a general hospital in Taipei. They were randomly assigned to either the intervention (n=47) or comparison group (n=47). The intervention group received a 12-week home-based resistance training program and the comparison group received standard rehabilitation exercises instruction without resistance training. Data were collected at baseline, 2-weeks, 6-weeks, and 12-weeks post operation. The outcome measurements were 30-second chair sit-to-stand testing, up-and-go time, timed walking distance, Harris Hip Score (HHS), range of motion and The Western Ontario and McMaster Universities Osteoarthritis index (WOMAC). Results: The mean age of study participants was 67.3 years (range: 55 to 90). The majority of the study participants were females (n=67, 71.3%). The demographics and disease characteristics were balance between two study groups. To minimize the influence of the surgery on outcomes, the study used double baseline, the preoperative and 2 weeks postoperative measures. The measures on all outcome variables were balance at these two baselines. Results of generalized estimating equations showed statistically significant between group effect for 30-second chair sit-to-stand testing (β=1.69, 95%CI = 0.08-3.29, p = .040), timed walking distance (β= 29.14, 95%CI =-8.75-67.02, p = .016), and WOMAC (β= -8.38, 95%CI = -12.94- -3.82, p＜.001). There were also significant group by time interactions for hip function, hip adduction, and hip external rotation. The hip adduction and hip external rotation both were significantly greater in the intervention group at week 12 than they were in the comparison group at week 2 (β= 5.48, 95%CI = 0.95-10.02, p =.018; β= 4.41, 95%CI = 0.84-7.99, p = .015, respectively). The hip abduction was significantly greater in the intervention group at week 6 than it was in the comparison group at week 2 (β= 4.06, 95%CI = 0.68-7.43, p =.019). Conclusions / Implications for Practice: The study results support that the home-based resistance band exercise program is effective for improving postoperative lower limb muscle strength, functional exercise capacity, hip function, health-related quality of life, and range of motion in patients with total hip arthroplasty. In considering the low cost and convenience of a home-based resistance training program, health professionals should take such exercises into consideration while providing guidance to patients with total hip arthroplasty.

habitat description, forty sample plots were stratified randomly. A TWINSPAN classification,
refined by Braun-Blanquet procedures, was carried out on the Viewpoint section of the reserve. Ten
plant communities, grouped into five major community types, were identified. The veld condition
and ecological carrying capacity in these communities were measured, stating an abundance of food
on long grass while the short grass equal the number of short grass feeders. A number of behavioural
aspects such as activity data, home range utilization and dietary usage were examined. Statistical
methods such as the Spearman rank-order correlation, Wilcoxon sign test and Student T-test were
used on rhino data. The difference in usage of the home range during wet and dry seasons was
insignificant.Environmental Sciences
