Abstract:
Through N-dimensional person space, the article gives measures of test parameters and item statistics, including difficulty/discriminating value of test, correlations between a pair of items, and item-total correlations with binary items using angular similarity between two vectors. Relationships between difficulty value and discriminating value of items and test were derived, including relationship between test reliability and test discriminating value. Reliability of a test as per theoretical definition in terms of length of score vectors of two parallel subtests and angle between such vectors was derived. The method was extended to find reliability of a battery of tests. Reliability and discriminating value of a Likert-type item and scale was found in terms of angular similarity without involving assumptions of continuous nature or linearity or normality for the observed variables, or the underlying variable being measured. The proposed methods also avoid test of unidimensionality or assumption of normality or bivariate normality associated with the polychoric correlations. Thus, the proposed methods are in fact nonparametric and considered as improvement over the existing ones. Reliability as a measure of association of two vectors and discrimination as a measure of distance between the vectors are likely to show a negative relationship.

Based on the theory of Fabry-Perot interference, we analyzed the inherent relationship between single-wavelength and the spectrometry, established the mathematical model of transformation from angular spectrum measurement to spectral measurement,realized the data conversion between angular spectrum measurement and spectrum measurement; build the experimental platform and got the laser's transmittance by changing the incidence angle of the laser, and given the comparison experiment by using spectrophotometer, measured the spectral transmittance of filters. Comparison of the two measurement, the results show that:it is a feasible scheme that the angular spectrum measurement replace spectral measurement for filter transmittance .

Abstract:
Background People poststroke often walk with a spatiotemporally asymmetric gait, due in part to sensorimotor impairments in the paretic lower extremity. Although reducing asymmetry is a common objective of rehabilitation, the effects of improving symmetry on balance are yet to be determined. Objective We established the concurrent validity of whole-body angular momentum as a measure of balance, and we determined if reducing step length asymmetry would improve balance by decreasing whole-body angular momentum. Methods We performed clinical balance assessments and measured whole-body angular momentum during walking using a full-body marker set in a sample of 36 people with chronic stroke. We then used a biofeedback-based approach to modify step length asymmetry in a subset of 15 of these individuals who had marked asymmetry and we measured the resulting changes in whole-body angular momentum. Results When participants walked without biofeedback, whole-body angular momentum in the sagittal and frontal plane was negatively correlated with scores on the Berg Balance Scale and Functional Gait Assessment supporting the validity of whole-body angular momentum as an objective measure of dynamic balance. We also observed that when participants walked more symmetrically, their whole-body angular momentum in the sagittal plane increased rather than decreased. Conclusions Voluntary reductions of step length asymmetry in people poststroke resulted in reduced measures of dynamic balance. This is consistent with the idea that after stroke, individuals might have an implicit preference not to deviate from their natural asymmetry while walking because it could compromise their balance.

This paper focuses on the application of fuzzy logic-Taguchi method for multi-objective optimization of the flexible segment in slider-rocker compliant mechanisms. The input parameters such as input torque and crank angular are optimized with considerations of the multiple performance measures as angular displacement and stress of the flexible segment. The results found that the input torque at level 3 of 60 Nm and crank angular at level 1 of 70 degrees are favorable parameters for compliant flapper mechanism. Based on analysis of variance (ANOVA), the results revealed that input crank angular is the most significant with hightest contribution of 48%.

Abstract:
Noncontact measurement for rotational motion has advantages over the traditional method which measures rotational motion by means of installing some devices on the object, such as a rotary encoder. Cameras can be employed as remote monitoring or inspecting sensors to measure the angular velocity of a propeller because of their commonplace availability, simplicity, and potentially low cost. A defect of the measurement with cameras is to process the massive data generated by cameras. In order to reduce the collected data from the camera, a camera using ERS (electronic rolling shutter) is applied to measure angular velocities which are higher than the speed of the camera. The effect of rolling shutter can induce geometric distortion in the image, when the propeller rotates during capturing an image. In order to reveal the relationship between the angular velocity and the image distortion, a rotation model has been established. The proposed method was applied to measure the angular velocities of the two-blade propeller and the multiblade propeller. The experimental results showed that this method could detect the angular velocities which were higher than the camera speed, and the accuracy was acceptable.

Abstract:
A research programme is described to develop an optical method to measure the instantaneous angular speed (lAS) of machinery in condition monitoring. In this research, special consideration is given to the development ofa non-contact method of measuring IAS using a laser mouse. Further development of its application to the detection ofparallel misalignment fault in condition monitoring is described. This research requires multidisciplinary design, involving the knowledge from measurement, electrical instruments, optics, mechanical engineering, majntenance engineering, modelling and programming. The research presented is a novel approach to non-contact measurement of lAS through the use of a laser mouse. Initial investigation of the characteristics of this device shows its potential for the measurement of lAS. The software application is developed to adapt the laser mouse to the Microsoft Windows operating system. Tests are carried out which show that the pixel variation acquired by the laser mouse has a linear relationship with its physical movement relative to the movement of the rotating shafts. Calibration tests show good correlation with the results of conventional, contact IAS measurement using a shaft encoder. It is concluded that using a laser mouse to measure the IAS is reliable method. An application of the IAS technique to the detection of the parallel shaft misalignment faults on a geared induction motor is described. Firstly, a mathematical model of IAS is developed for parallel misalignment. Secondly, a geared induction motor test rig is used to validate the model and to demonstrate the practical efficacy of IAS measurement by a laser mouse as a condition monitoring tool for detecting and identifying such faults. Finally, in agreement with the lAS model, the motor test rig is applied to show that parallel misalignment can be identified from the features extracted from the lAS data produced by the laser mouse. Specially, in the time domain, the amplitude of IAS waveform and the standard deviation of the IAS variation have a great increase when the parallel misalignment is occurred. The increase of the magnitude of parallel misalignment can make the amplitude of IAS waveform and the standard deviation of the IAS variation larger. In the frequency domain, the amplitude of the first component of rotational frequency appears much higher than those of the 2nd and 3rd components and has more increases, when the parallel misalignment is occurred. As the fault severity increased, the key characteristic of IAS spectra is a rise in the level of the first component of rotation frequency. The sensitivity of IAS to variations in power supply frequency and torque is also investigated using the motor test rig. It is found that variation in power supply frequency can increase in the value of the amplitude of IAS waveform and the standard deviation of IAS variation in the time domain, and can also increase in the amplitude of first component of rotational frequency in IAS spectra in the frequency domain. However, there is found to be little change in IAS with variation in torque. In conclusion, the laser mouse approach to non-contact measurement of lAS presented in this thesis can be used as an alternative to existing contact and non-contact methods, and the IAS technique can be used to identify the parallel misalignment faults in condition monitoring.

Abstract:
Polarised synchrotron emission from the Milky Way is of interest for its role as a foreground to the polarised CMB and as a probe of the interstellar medium. The Galactic ALFA Continuum Transit Survey (GALFACTS) and the Global Magneto-Ionic Medium Survey (GMIMS) are two ongoing surveys of the diffuse polarised emission around 1.4 GHz, with wide bandwidths and high frequency-resolution. In this thesis, I use early data from GALFACTS to investigate the behaviour of polarised, diffuse Galactic synchrotron emission. I also analyse GMIMS total intensity data. I derive a rotation measure (RM) map of the GALFACTS sky using a combination of RM-synthesis and linear angle fitting, commenting on the structure of the maps in general and on specific regions in particular. Overall I find that the maps are rich in features, and probe the RM structure of the extended Galactic emission with reasonable accuracy. I also derive the Angular Power Spectrum (APS) of the polarised emission for thirty-one 15 by 15 degree subregions across the GALFACTS data. I compute the E- and B-modes (E+B) and the scalar APS of the polarised emission (PI). I parametrise the APS by fitting a power law to the data. Comparing the E+B APS to the PI APS shows that E+B is consistently steeper across the sky. The APS data is also used to estimate the level of foreground contamination of the CMB B-mode by the synchrotron emission. I find that the slope of the APS averaged over high-latitude, low-emission subregions agrees exactly with that of the Planck 30 GHz polarised emission, thus setting an upper limit to the synchrotron contamination of CMB B-modes. Finally, I evaluate the spurious, systematic, temperature zero-level offset and associated uncertainty in preliminary GMIMS total intensity maps, finding a lower limit of ±0.26 K. I also make spectral index maps made using the GMIMS data and the Haslam et al. (1982) 408 MHz map, improving upon previous spectral index maps in the literature.

It was established that the frontal plan up and down movements performed by the equine has impact on the rider’s pelvis in movements of lateral inclination. The back and forth movements in sagittal plan generate ante and retroversion movements. On the other hand, the right and left movements in transverse plan result in pelvic rotations. Such movements are similarly executed by the human being pelvis, this way, the rider physically prevented from walking, passively experiences while riding, the same amount of pelvis displacement and rotation during the biped march. Due to the importance of this movement quality, this work has as objective analyze the equine conformation of the equine center of the Rehabilitation and Readaptation center Dr. Henrique Santillo (CRER). It is a transverse study, which used 180 cm tape measure, hipometer, reflexive markers, cameras and kinematical analysis software Kinovea, to evaluate the linear and angular parameters, together with five zootechnical indexes. Eight half-breed equines, aged between 3 to 17 years, were evaluated, they were destinated exclusively to the equine therapy practice. The statistical analysis was descriptive and analytic. The corporeal index average was 0, 85, the relation between the back height and the substernal fail height was 1, the conformation index 2, 1125, indicating the suitable animals for march and saddle. In the actual study, the animals presented smaller neck and head scapular length in relation to other equine conformation studies. The thoracic cavity depth determines cardiopulmonary performance and provide to the equine therapy, long working hours. On the CRER equines, the average obtained was high. On the forearm, knee and shank regions, it is ideal to be hypertrophied, to protect from possible injuries, reflex of good management practices and then, it was observed in the animals. There should be correspondence between the angles of the thoracic, or accommodation members and the pelvic or propulsive ones, and some angles of this study had correspondence, as the humerus-radius and the coxofemoral and in relation to the solo phalanges. As a conclusion, The CRER equines kept proportionality regarding to some variables as the thorax perimeter, the head length and width and the scapula angulation and the solo phalanges. The zootechnical indexes determine that the animals are suitable for the equine therapy practice. Regarding to the other parameters, they didn’t obtain proportionality, which can interfere in the pace progress, this justifies the using of specific tools as the ones used in this study for the adequate choice of equines for equine therapy and the need for more studies in other centers for comparison.<br>O equino apresenta-se como uma importante ferramenta cinesioterapêutica, isto ocorre porque ao andar realiza movimentos tridimensionais que se desdobram em ações musculares coordenadas e sincronizadas no cavaleiro, o que pode justificar sua aplicação terapêutica em humanos pessoas com deficiências. Constatou-se que os movimentos para cima e para baixo no plano frontal executado pelo equino, repercutem na pelve do cavaleiro em movimentos de inclinação lateral. Os movimentos para frente e para trás no plano sagital geram movimentos de antero e retroversão. Por sua vez, os movimentos para a direita e esquerda no plano transversal resultam em rotações pélvicas. Tais movimentos são similarmente executados pela pelve do ser humano, e desse modo, o cavaleiro fisicamente impedido de andar, experimenta passivamente ao cavalgar a mesma quantidade de deslocamento e rotação da pelve durante a marcha bípede. Devido a importância da qualidade deste movimento este trabalho tem por objetivo analisar a conformação de equinos do Centro de Equoterapia do Centro de Reabilitação e Readaptação Doutor Henrique Santillo (CRER). Trata-se de um estudo transversal que utilizou fita métrica de 180 cm, hipômetro, marcadores reflexivos, máquina fotográfica e software de análise cinemática Kinovea®, para avaliação dos parâmetros lineares e angulares, juntamente com cinco índices zootécnicos. Foram avaliados oito equinos mestiços, com idades de 3 à 17 anos, destinados exclusivamente á prática da Equoterapia. A análise estatística foi descritiva e analítica. A média do índice corporal foi de 0,85, da relação entre a altura do costado e a altura do vazio subesternal foi 1, do índice de conformação 2,1125, indicando os animais aptos para marcha e sela. No presente estudo, os animais apresentaram menor comprimento escapular, de pescoço e cabeça em relação a outros estudos de conformação com equinos. A profundidade da caixa torácica determina o rendimento cardiorrespiratório e proporciona para equoterapia períodos longos de trabalhos. Nos equinos do CRER, a média obtida foi alta. Nas regiões do antebraço, joelho e canela o ideal é que sejam hipertrofiados, para proteção de possíveis lesões, reflexo de boas práticas de manejo e, assim, foi observado nos animais. Deve existir correspondência entre os ângulos dos membros torácicos, ou de acomodação, e pélvicos ou propulsores, e alguns ângulos deste estudo tiveram correspondência, como o úmero-radial e coxofemoral e em relação às falanges solo. Como conclusão, os equinos do CRER mantiveram proporcionalidade em relação a algumas variáveis como o perímetro do tórax, o comprimento e largura da cabeça e as angulações da escápula e as falanges solo. Os índices zootécnicos determinaram que os animais estão aptos para a prática de Equoterapia. Em relação aos demais parâmetros não obtiveram proporcionalidade, o que pode interferir no andamento do passo, o que justifica a utilização de ferramentas específicas como as utilizadas neste estudo para a escolha adequada de equinos para Equoterapiae a necessidade de mais estudos em outros centros para comparação.

Abstract:
Meson production in proton-deuteron collisions has been studied using the WASA detector facility at the CELSIUS storage ring in Uppsala. Data were obtained at two different beam energies, 1360 MeV and 1450 MeV, slightly above threshold for η and ω mesons. The differential cross sections of pd → 3He ω constitute the first measurements of this reaction covering the whole angular range. The ω angular distributions are isotropic at 1360 MeV but have strong forward and backward enhancements at 1450 MeV. Theoretical calculations using a two-step model fail to reproduce the shapes of the angular distributions and underestimate the total cross sections. The tensor polarisation of the ω meson has been derived from the measured angular distributions of the ω decay products. The π+ π- π0 and the π0 γ decay channels gave consistent results, showing that the ω meson is produced unpolarised at both energies. This is in contrast to a recent MOMO measurement which showed that the Φ meson is produced almost completely polarised in the pd → 3HeΦ reaction. Different production dynamics of ω and Φ mesons close to threshold raises the question whether the Okubo-Zweig-Iizuka (OZI) rule is applicable in low-energy nucleon-nucleon reactions. The angular distributions of the η meson produced in the pd → 3He η reaction are strongly enhanced for forward going η mesons at both energies. The σ(pd → 3He π+ π- π0 )/σ(pd → 3He π0 π0 π0 ) ratio has been measured and discussed in terms of isospin amplitudes. A rough estimate of the pd → 3He π0 π0 π0 π0 cross sections has also been obtained and the pd → 3He η π0 reaction has been studied for the first time near threshold.

Abstract:
In an extensive outdoor propagation study, low antenna heights of 1.7 m are used at both the transmitter and the receiver to measure over 3500 wideband power-delay profiles (PDPs) of the channel for a peer-to-peer communications system. Rural and urban areas are studied in 22 different transmitter-receiver links. The results are used to characterize the narrowband path loss, mean delay, root-mean-square (RMS) delay spread, and timing jitter of the peer-to-peer wideband channel. Small-scale fading characteristics are measured in detail by measuring and analyzing 160 PDPs within each local area. This thesis shows the measurement setup for the calculation of fading rate variance and angular spread and reports the first known attempt to calculate angular spread from track power measurements. New analysis presented in this thesis shows the effect of measurement error in the calculation of angular spread. The expected characteristics of angular spread are derived using two different angle-of-arrival (AOA) models from the literature. Measurement results show initial validation of Durgin's angular spread theory. A new measurement-based algorithm for simulating wideband fading processes is developed and implemented. This simulation technique shows promise in the simulation of high-bit rate peer-to-peer radio communication systems.<br>Master of Science

Abstract:
Noethers theorem shows that continuous global symmetries lead classically to conservation laws. Such symmetries can be divided into spacetime and internal symmetries. The invariance of Minkowski space-time under global Poincaré transformations leads to the conservation of the four-momentum and the total angular momentum. Examples for conserved charges due to internal symmetries are electric and colour charge. The vacuum expectation value of a Noether current is shown to beconserved in a quantum field theory if the symmetry transformation keeps the path-integral measure invariant.

Abstract:
How do black holes grow? There is a lot of matter orbiting around a black hole and this matter can interact with itself, but must observe the laws of gravity and conservation of angular momentum. ‘Eating more and growing bigger’ explains that the accreting matter is very often in the form of a disc. It goes on to discuss what accretion discs look like, how hot they are, and how you measure how fast a black hole is spinning. How close matter is able to orbit before being swallowed by the black hole tells you how fast the black hole itself must be spinning.

Abstract:
AbstractIn this chapter, we first explain the concept of an axial line and how the axial map is applied in space syntax. We then discuss the static measure of ‘connectivity’ with its ‘one-step’ to ‘n-step’ logic, including its meaning for axialintegration analysis. We further present the segment integration analysis. Using the streetsegment as the basis for analysis allows one to apply three types of distances and three types of radii in space syntax. We then present the most-often used space syntax measures in more depth, namely angularchoice and angular integrationwith metric radius, and introduce the mathematical formulae on how to normalise both measures. Real-life applications illustrate and underpin the usefulness of these measures and their meaning for urban analysis, such as why and how they allow us to identify urban societal processes and their added value at both a citywidescale and a neighbourhoodscale. Finally, we critically reflect on the measures, including their potentials and misfits. Exercises are provided at the end of the chapter.

Abstract:
Let us begin by reminding ourselves just what we mean by “the inherent optical properties” and “the apparent optical properties” of surface waters. The inherent optical properties are those that belong to the aquatic medium itself: properties that belong to a small sample of the aquatic medium taken out of the water body just as much as they belong to a great mass of the medium existing within the water body itself. The properties of particular concern to us are the absorption coefficient, a, the scattering coefficient, b, and the volume scattering function, β(θ). The absorption coefficient at a given wavelength is a measure of the intensity with which the medium absorbs light from a parallel beam per unit pathlength of medium (see Eq. 1.18). The scattering coefficient at a given wavelength is a measure of the intensity with which the medium scatters light from a parallel beam per unit pathlength of medium (see Eq. 1.17). Both a and b have the units, m-1. The normalized volume scattering function specifies the angular (θ) distribution of single-event scattering around the direction of a parallel incident beam. It is often normalized to total scattering and referred to as the scattering phase function, P(θ) (see Eq. 1.21). Since these properties belong, as I have already said, to a small sample of the medium, just as much as they do to a great slab of ocean, they can be measured in the laboratory. The absorption coefficients at various wavelengths can be measured with a suitable spectrophotometer: the scattering coefficient and the volume scattering function can be measured with a light scattering photometer. The apparent optical properties are not properties of the aquatic medium as such although they are closely dependent on the nature of the aquatic medium. In reality they are properties of the light field that, under the incident solar radiation stream, is established within the water body.

Abstract:
Recently, it has been discovered that RF waveguides can be used as onboard wireless sensors for the direct measurements of angular positions of a moving object and that a combination of RF waveguides may be used to measure full spatial angular orientation of the object. This paper deals with the computational issues that arise in resolving the spatial orientation from the measurement data of a set of RF waveguide sensors. The paper presents an algorithm that combines a heuristic search method with the least-squares approach for computing the full orientation of an object. The goal is to develop a general and efficient method for computing spatial orientation from the sensor data of a class of angular position sensors that have smooth sensor profiles.

Abstract:
Vibration compaction is the most effective way of compacting coarse-grained materials. The effects of vibration frequency and amplitude on the compaction density of different backfill materials commonly used by INDOT (No. 4 natural sand, No. 24 stone sand, and No. 5, No. 8, No. 43 aggregates) were studied in this research. The test materials were characterized based on the particle sizes and morphology parameters using digital image analysis technique. Small-scale laboratory compaction tests were carried out with variable frequency and amplitude of vibrations using vibratory hammer and vibratory table. The results show an increase in density with the increase in amplitude and frequency of vibration. However, the increase in density with the increase in amplitude of vibration is more pronounced for the coarse aggregates than for the sands. A comparison of the maximum dry densities of different test materials shows that the dry densities obtained after compaction using the vibratory hammer are greater than those obtained after compaction using the vibratory table when both tools were used at the highest amplitude and frequency of vibration available. Large-scale vibratory roller compaction tests were performed in the field for No. 30 backfill soil to observe the effect of vibration frequency and number of passes on the compaction density. Accelerometer sensors were attached to the roller drum (Caterpillar, model CS56B) to measure the frequency of vibration for the two different vibration settings available to the roller. For this roller and soil tested, the results show that the higher vibration setting is more effective. Direct shear tests and direct interface shear tests were performed to study the impact of particle characteristics of the coarse-grained backfill materials on interface shear resistance. The more angular the particles, the greater the shear resistance measured in the direct shear tests. A unique relationship was found between the normalized surface roughness and the ratio of critical-state interface friction angle between sand-gravel mixture with steel to the internal critical-state friction angle of the sand-gravel mixture.
