description: Walking for most humans and animals is an easy task due to the inherent robustness and the natural dynamics of the walking mechanism. Walking, however, for humanoid robots is not that easy because of its nonlinearity, high dimensionality, and natural instability. Effective use of humanoid robots in unstructured environments for human beings requires that they have autonomous and reliable locomotion capability. Locomotion for humanoid robots can take many forms. This thesis covers motion plan and control of humanoid walking robots. Five consecutive stages are addressed from the perspective of stable dynamic walking. Firstly, a natural and efficient walking pattern is designed on the basis of the insight gained from human walking. The walking pattern involves the configuration with stretched knees. Secondly, in view of the modeling error, as well as the environment uncertainty such as the unevenness and inclination of the surface, a posture controller, which online controls the orientation of the upper body of the robot is developed from the viewpoint of stability. Walking stability of the robot is improved through the control scheme. In the third stage, a gait controller, which online controls the swing-leg is developed. Fast and precise trajectory tracking of the swing-leg is achieved which enables humanoid robots to quickly swing the swing-leg so that fast walking can be realized. In the fourth stage, a controller with the purpose of decreasing the landing force and improving the walking stability by means of force control is developed. In the final stage, strategies for restoring equilibrium in the presence of external disturbances to maintain upright standing posture are analyzed. Simple models are introduced to exploit boundaries that determine the strategies used for preventing a fall. Simulation and experiments were performed with the humanoid robot NAO developed at Aldebaran Robotics in France. Using the walking system, NAO achieved dynamic stable walking and reached a maximum walking speed of 0.24 m/s in experiments. Besides, with the presented walking pattern NAO could walk stably with almost stretched knees at a lower speed, e.g. 0.10 m/s, so that the corresponding energy consumption was lower since the robot did not bend the knees all the time, which means that the robot is able to walk for a longer time without battery charging and has less heating problem.

description: Eine gut strukturierte und geführte Schulbibliothek kann einen entscheidenden Beitrag zur Chancengleichheit im Bildungssystem leisten, indem sie die Lesekompetenz fördert und sich Kinder und Jugendliche zu informations- und medienkompetenten Nutzern entwickeln. Neben der Darstellung der Situation der Schulbibliotheken in Deutschland sowie der gängigen Praxis schulbibliothekarischer Arbeit wird der Nutzen von Schulbibliotheken und deren erforderlichen Einrichtung an allen Schulen aufgezeigt. Am Beispiel eines in Eigenregie geführten Medien- und Arbeitszentrums eines Gymnasiums in NRW wird mithilfe empirischer Methoden der qualitative Istzustand analysiert. Darauf aufbauende Handlungsempfehlungen sollen zur Verbesserung der Bibliotheksarbeit beitragen. Anhand des vorgestellten Konzeptes werden allgemeingültige Anregungen zum Aufbau oder zur Optimierung anderer Schulbibliotheken gegeben.

Interlayer exchange coupling -- a general scheme turning chiral magnets into magnetic multilayers carrying atomic-scale skyrmions

description: We report on a general principle using the interlayer exchange coupling to extend the regime of chiral magnetic films in which stable or metastable magnetic skyrmions can appear at zero magnetic field. We verify this concept on the basis of a first-principles model for a Mn monolayer on W(001) substrate, a prototype chiral magnet for which the atomic-scale magnetic texture is determined by the frustration of exchange interactions, impossible to unwind by laboratory magnetic fields. By means of \textit{ab initio} calculations for the Mn/W$_m$/Co$_n$/Pt/W(001) multilayer system we show that for certain thicknesses $m$ of the W spacer and $n$ of the Co reference layer, the effective field of the reference layer fully substitutes the required magnetic field for skyrmion formation.

description: In this paper we study the properties of the chaotic wave fields generated in the frame of the Kundu-Eckhaus equation (KEE). Modulation instability results in a chaotic wave field which exhibits small-scale filaments with a free propagation constant, k. The average velocity of the filaments is approximately given by the average group velocity calculated from the dispersion relation for the plane-wave solution however direction of propagation is controlled by the $β$ parameter, the constant in front of the Raman-effect term. We have also calculated the probabilities of the rogue wave occurrence for various values of propagation constant k and showed that the probability of rogue wave occurrence depends on k. Additionally, we have showed that the probability of rogue wave occurrence significantly depends on the quintic and the Raman-effect nonlinear terms of the KEE. Statistical comparisons between the KEE and the cubic nonlinear Schrodinger equation have also been presented.

description: We propose a modification to the Lie algebra $S$-expansion method. The modification is carried out by imposing a condition on the $S$-expansion procedure, when the semigroup is given by a cyclic group of even order. The $S$-expanded algebras are called $S_{H}$-expanded algebras where $S=Z_{2n}$. The invariant tensors for $S_{H}$-expanded algebras are calculated and the dual formulation of $S_{H}$-expansion procedure is proposed. We consider the $S_{H}$-expansion of the five-dimensional $AdS$ algebra and its corresponding invariants tensors are found. Then a Chern-Simons Lagrangian invariant under the five-dimensional $AdS$ algebra $S_{H}$-expanded is constructed and its relationship to the general relativity is studied.

description: Cyclophotocoagulation is a unique method of treating complex eye diseases. The method is prescribed in the case of a blind eye, with constant pain syndrome and in the final terminal stage of glaucoma. The unpredictability of the hypotensive effect and a number of serious complications during continuous wave cyclophotocoagulation (CFC) limit the use of this operation in the treatment of glaucoma, which led to the development of a new approach known as microimpulse transcleral CFC (mCFC).

description: Streams can attenuate inputs of phosphorus (P) and therefore dampen the likelihood of ecosystem eutrophication. This P attenuation derives from many processes and remains poorly understood, particularly in reference to the geochemical mechanisms involved. We studied P attenuation in the form of (1) potential for mineral (co-)precipitation from the water column and (2) P sorption with benthic sediments. We hypothesized that both mechanisms vary with catchment geology and that P sorption depends on sediment reactive iron (Fe). We sampled 31 streams at baseflow, covering a gradient of P inputs (via land use), hydrological characteristics, and catchment geologies. Geochemical equilibria in the water column were measured and benthic sediments were analyzed for sorption properties and P and Fe fractions. Neither P-containing minerals nor calcite-phosphate co-precipitation had the potential to form. However, in-stream dissolved reactive P (DRP) correlated with labile sediment P (water soluble and easily reduced Fe-P) for streams where hyporheic exchange between the water column and sediment porewaters was likely sufficient. Because this labile P was associated with poorly crystalline Fe oxides, which determined P sorption capacity, we observed that more sorptive sediments were positively related to DRP concentrations. Our results suggest that DRP attenuation in these streams at baseflow depends in part on the combination of biogeochemical Fe and P cycles and the hydrological exchange with the hyporheic zone. Such combinations will likely vary spatiotemporally within a catchment and must be considered alongside inputs of P and sediment if the P concentrations at baseflow, and eutrophication risk, are to be well managed.

description: Overgrazing is one of the major land-use impacts in Mongolia leading to habitat degradation and subsequent impairment of biological diversity. This study examined macroinvertebrate diversity among sites with different grazing intensities in Hövsgöl, Mongolia, to test whether the taxonomic and functional structure of the macroinvertebrate community differs among streams with different grazing intensity. The 14 551 total identified specimens comprised 78 genera in 27 macroinvertebrate families from the 6 study streams. Exponential Shannon index and weighted functional diversity were significantly higher in low grazing sites than in moderate and high grazing sites; no significant difference was found between moderate to high grazing intensity. Macroinvertebrate community composition was not significantly different between low and moderate or low and high grazing intensity sites. SIMPER analysis revealed the taxon with the highest contribution to dissimilarity among the levels of grazing. Thirteen trait categories from 8 traits differed significantly between sites with varying grazing pressure. The community-weighted means for 4 of these traits were filtered by high grazing intensity: dissemination, resistant form, current velocity, and saprobity. Although the other 4 traits differed significantly, they did not respond directly to grazing intensity. Further knowledge of traits, especially regarding physiological capabilities, is needed to better understand macroinvertebrate/environment relationships, but overall, these findings suggest that macroinvertebrate diversity components were affected by grazing.

description: Five different texture methods are used to investigate their susceptibility to subtle noise occurring in lung tumor Computed Tomography (CT) images caused by acquisition and reconstruction deficiencies. Noise of Gaussian and Rayleigh distributions with varying mean and variance was encountered in the analyzed CT images. Fisher and Bhattacharyya distance measures were used to differentiate between an original extracted lung tumor region of interest (ROI) with a filtered and noisy reconstructed versions. Through examining the texture characteristics of the lung tumor areas by five different texture measures, it was determined that the autocovariance measure was least affected and the gray level co-occurrence matrix was the most affected by noise. Depending on the selected ROI size, it was concluded that the number of extracted features from each texture measure increases susceptibility to noise.

description: Thermal fluctuations cause perturbations of fluid-fluid interfaces and highly nonlinear hydrodynamics in multiphase flows. In this work, we develop a novel multiphase smoothed dissipative particle dynamics model. This model accounts for both bulk hydrodynamics and interfacial fluctuations. Interfacial surface tension is modeled by imposing a pairwise force between SDPD particles. We show that the relationship between the model parameters and surface tension, previously derived under the assumption of zero thermal fluctuation, is accurate for fluid systems at low temperature but overestimates the surface tension for intermediate and large thermal fluctuations. To analyze the effect of thermal fluctuations on surface tension, we construct a coarse-grained Euler lattice model based on the mean field theory and derive a semi-analytical formula to directly relate the surface tension to model parameters for a wide range of temperatures and model resolutions. We demonstrate that the present method correctly models the dynamic processes, such as bubble coalescence and capillary spectra across the interface.

Such combinations will likely vary spatiotemporally within a catchment and must be considered alongside inputs of P and sediment if the P concentrations at baseflow – and eutrophication risk – are to be well managed.

description: Understanding the spatial relationships between land use/land cover (LULC) and physicochemical water quality in pond ecosystems is vital to the conservation and management of ponds. This knowledge is especially critical to reconcile landscape planning and management, particularly in urban regions with rapid population growth. In this study we measured (1) seasonal differences in water quality and (2) the impact of the surrounding landscape at 4 spatial scales (10 m, 100 m, 500 m, and full catchment) on water quality of 50 ponds in the Auckland region, New Zealand. For each pond, 9 physicochemical water quality variables and 9 landscape properties (LULC and physical features of the ponds) were measured in winter and summer. We found significantly higher measures of conductivity, total dissolved solids, percentage of dissolved oxygen at saturation (%DO), pH, salinity, and phosphate concentrations in summer. By contrast, ammoniacal nitrogen concentration was higher in winter. These findings indicated impaired water quality during summer. Multiple linear regression and redundancy analyses showed that LULC and physical landscape features had different influences on the physicochemical variables across the different spatial scales and seasons. The landscape properties at all 4 spatial scales were good indicators of pond temperature and %DO only in summer. Overall, variations in pond water quality were explained better by general landscape characteristics than by LULC alone at the catchment and 500 m scale in winter and at the 100 m scale in summer. This study highlights the importance of including different spatial scales, seasons, and landscapes when quantifying land–water interactions.

description: We investigate a hybrid metallic island / single dopant electron pump based on fully-depleted silicon on insulator technology. Electron transfer between the central metallic island and the leads is controlled by resonant tunneling through single phosphorus dopants in the barriers. Top gates above the barriers are used control the resonance conditions. Applying radio frequency signals to the gates, non-adiabatic quantized electron pumping is achieved. A simple deterministic model is presented and confirmed by comparing measurements with simulations.
Solidarity on the Margins: Narrating Zainichi in Yi Yang-ji’s “Woman Diver” (Kazukime, 1983) and Nakagami Kenji’s “Flower Boy” (Fuaramu, 1980)

description: Among the oppressed minority groups in Japan are the Zainichi (Korean residents in Japan) and the Hisabetsu Burakumin (lit.“discriminated-against outcastes”; referred to in this paper using the term Burakumin). Members of both groups have produced prominent works of literature. Yi Yang-ji (1955–1992), one of the most important and well-studied Zainichi writers, is known for her female Zainichi characters with fractured identities. Although not a Zainichi himself, Burakumin writer Nakagami Kenji (1946–1992) advocated for and wrote about the Zainichi community, addressing issues ranging from family strife to historical trauma. Previous studies of Yi have emphasized the power of femininity in her characters, examining her work through the lens of postcolonial theory and situating it within the framework of “border-crossing” literature. Building on previous scholarship, I adopt a comparative approach in examining the representation of the Zainichi in Yi’s “Woman Diver” (Kazukime, 1983) and in Nakagami’s “Flower Boy” (Fuaramu,1980). Drawing on the theory of “postmemory” from Holocaust studies, I argue that the solidarity forged by characters and writers on the social and political margins defies the structures of Japanese imperialism and subverts the ideology of Japanese nationalism. By reconstructing the lived experiences of the Zainichi, Yi and Nakagami allow the periphery to narrate itself and resist the stigmatizing narrative of the center. Through a comparative study of “Woman Diver” and “Flower Boy”, I rethink the categorization of zainichi bungaku (Zainichi literature) and explore how the interaction between marginalized groups challenges the imperial structures pervasive in Japanese society.

A fractal dimension based optimal wavelet packet analysis technique for classification of meningioma brain tumours
Creators: name: Al-Kadi, Omar S.

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: With the heterogeneous nature of tissue texture, using a single resolution approach for optimum classification might not suffice. In contrast, a multiresolution wavelet packet analysis can decompose the input signal into a set of frequency subbands giving the opportunity to characterise the texture at the appropriate frequency channel. An adaptive best bases algorithm for optimal bases selection for meningioma histopathological images is proposed, via applying the fractal dimension (FD) as the bases selection criterion in a tree-structured manner. Thereby, the most significant subband that better identifies texture discontinuities will only be chosen for further decomposition, and its fractal signature would represent the extracted feature vector for classification. The best basis selection using the FD outperformed the energy based selection approaches, achieving an overall classification accuracy of 91.25% as compared to 83.44% and 73.75% for the co-occurrence matrix and energy texture signatures; respectively.

description: 1. Cleomella angustifolia Torrey (1850: 255)
 Lectotype (designated here): U.S. Dragon Expedition [referred to by Torrey (1850) as on the Upper Plate], Beyrich s.n. (NY 02256363!).
 Note: The original description of Cleomella angustifolia referenced four specimens: “Western Arkansas, Dr. James. On the Upper Patte, Mr. Beyrich. San Felipe, Texas, Drummond. High Praries west of Houston, Lindheimer.” (Torrey 1850: 255). Three of these are labelled “Torrey Herbarium” (NY), with the Drummond and Beyrich collections together on one sheet, and the Lindheimer collection is labeled “Meisner Herbarium” (NY). The collection of Dr. James was the first of this species seen by Torrey, though originally referred to as C. mexicana DC. (Torrey 1828). However, of the material used in the original description, it is not the best representative of the species. The Beyrich, Drummond, and Lindheimer collections are more complete, though the Beyrich specimen has the best collection of leaves, flowers, and fruits with obvious seeds inside. The James, Beyrich, and Drummond specimens also all have annotations in John Torrey’s hand as Cleomella angustifolia. For these reasons we are here designating the Beyrich collection as the lectotype of Cleomella angustifolia.

description: Dentro del medio laboral, el trabajador interactúa con diferentes condiciones de trabajo que pueden afectarlo positiva o negativamente, es por esto que el trabajo puede convertirse en un instrumento de salud como de enfermedad para el individuo, la empresa y la sociedad. Es de vital importancia determinar los efectos desfavorables de las condiciones de trabajo como accidentes de trabajo, enfermedades profesionales, ausentismo, rotación de personal y mal clima organizacional, que pueden generar una disminución de la productividad de la empresa, un deterioro de la calidad de vida de los trabajadores y por consiguiente, pérdidas económicas para la misma. La salud ocupacional se encamina a la intervención activa de todos los niveles empresariales con el fin de mejorar las condiciones de trabajo y de salud de los trabajadores, mediante la promoción de la salud y la prevención y control de los factores de riesgo, de manera que estimulen el bienestar y la productividad de la empresa y sus empleados. Para ello es importante conocer la estructura organizacional de la empresa, sus procesos productivos, sus instalaciones y su distribución demográfica. De ahí que una herramienta fundamental es la elaboración del Panorama de Factores de Riesgo (PFR), lo que permitirá identificar, valorar y priorizar los factores de riesgo que se encuentran en cada puesto de trabajo y así poder tomar las medidas que permitan su control preventivo y correctivo evitando de esta forma la aparición de enfermedades profesionales y la ocurrencia de accidentes de trabajo, por medio de la elaboración de los programas de medicina preventiva y del trabajo y, el de higiene y seguridad industrial según lo establecido por la resolución 1016 de 1989. Por último, es importante organizar el programa de salud ocupacional teniendo en cuenta la asignación de recursos humanos, técnicos, financieros y locativos, los niveles de responsabilidad y la coordinación del mismo. Es por ello que se presenta a continuación el Diseño del Programa de Salud Ocupacional debido a la importancia que representa para el grupo empresarial ORCO - DESA.

description: Using a mulit-reflection time-of-flight mass spectrograph (MRTOF-MS) located after a gas cell coupled with the gas-filled recoil ion separator GARIS-II, the masses of several heavy nuclei have been directly and precisely measured. The nuclei were produced via fusion-evaporation reactions and separated from projectile-like and target-like particles using GARIS-II before being stopped in a helium-filled gas cell. Time-of-flight spectra for three isobar chains, 205Fr-205Rn-205At-205Po, 206Fr-206Rn-206At and 201Rn-201At-201Po-201Bi, were observed. Precision atomic mass values were determined for 205,206Fr, 201At, and 201Po.
