measurement unit (IMU) to navigate an Unmanned Aerial Vehicle (UAV) in a
previously unknown environment. The approach consists of two parts. First,
we apply a state-of-the-art simultaneous localization and mapping (SLAM)
method to the video stream of a onboard camera. From the SLAM system,
an up-to-a-scale pose of the camera is estimated, because the absolute size
of the environment cannot be estimated with a single camera. Second, the
estimated pose is fused with the data from IMU to resolve the scale ambiguity.
While analyzing the performance of the system, we find that the conver-
gence rate of scale decreases when the magnitude of scale increases. This
relationship has not been demonstrated and explained before. In this thesis,
we present an analysis and explanation of this phenomenon.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2017-12-01The student, Xinke Deng, accepted the attached license on 2015-12-07 at 23:03.The student, Xinke Deng, submitted this Thesis for approval on 2015-12-07 at 23:13.This Thesis was approved for publication on 2015-12-08 at 11:34.DSpace SAF Submission Ingestion Package generated from Vireo submission #8960 on 2016-03-02 at 14:07:5
Young People’s Housing Opportunity in Post-reform China
No full textThe inquiry that has culminated in this thesis was inspired by the challenges that many young Chinese people were facing when trying to gain access to affordable housing at the time of study, the early 2010s. By then, more than thirty years of housing reforms had completely changed how housing was being provided in China. The resulting structure had led young people to access housing in ways that were very different from those of their parents’ generation (Deng, Hoekstra & Elsinga, 2017). These observations prompted the following research question: What are the key factors defining young people’s opportunity to access housing, and how do these factors relate to China’s institutional changes during and after the market reform? The ensuing research has demonstrated that parental resources and intergenerational reciprocity are indispensable to the housing opportunity of young people, as home ownership has come to mediate the exchange of resources between...A+BE | Architecture and the Built Environment No 22 (2018)OLD Housing System
Dirac-Deng-Fan Problem with Coulomb-Hulthen Tensor Interactions
No full textThe relativistic symmetries of the Dirac equation within the framework of spin and pseudospin symmetries is investigated for Deng-Fan potential including the Coulomb-like and Hulthen-type potential tensor interaction terms. The energy eigenvalues and the corresponding wave function are obtained using the parametric generalization of Nikiforov-Uvarov method. We have also reported some numerical results and figures to show the effect of the tensor interactions
New and reassessed species of Strobilanthes (Acanthaceae) in the flora of China
No full textSeveral problems in Strobilanthes Blume (Acanthaceae: Ruelliae) are clarified as a result of collaboration between Chinese and western botanists. Examination of pollen has permitted clear delimitation of four morphologically similar species, Strobilanthes szechuanica (Batalin) J. R. I. Wood and Y. F. Deng, S. labordei H. Lév., S. wakasana Wakasugi and Naruhashi and S. wilsonii J. R. I. Wood and Y. F. Deng, the latter described for the first time in this paper, although first collected more than a hundred years ago. A key is provided to help distinguish these species. The globose, echinulate pollen found in several species from China and Japan and assigned to the genus Championella by Bremekamp is shown by SEM photography to be distinct from other pollen hitherto regarded as the same. Three new species, S. abbreviata Y. F. Deng and J. R. I. Wood, S. lihengiae Y. F. Deng and J. R. I. Wood and S. vallicola Y. F. Deng and J. R. I. Wood are described. S. austinii C. B. Clarke ex W. W. Sm. is lectotypified to show that it is conspecific with S. lamiifolia (Nees) T. Anderson, a species demonstrating trans-Himalayan links. New combinations are made for four species as the authors recognize only a single genus, Strobilanthes within the Strobilanthinae as defined by Bremekamp. S. gongshanensis Tsui and S. aenobarba W. W. Sm. are shown to be only varieties of S. inflata T. Anderson. Illustrations are provided for all new species. © 2006 The Linnean Society of London
Barcoding, linear and nonlinear analysis of full-day leg movements in infants with typical development and infants at risk of developmental disabilities: Cross-sectional study
No full text: Traditional methods do not capture the multidimensional domains and dynamic nature of infant behavioral patterns. We aim to compare full-day, in-home leg movement data between infants with typical development (TD) and infants at risk of developmental disabilities (AR) using barcoding and nonlinear analysis. Eleven infants with TD (2-10 months) and nine infants AR (adjusted age: 2-14 months) wore a sensor on each ankle for 7 days. We calculated the standard deviation for linear variability and sample entropy (SampEn) of leg acceleration and angular velocity for nonlinear variability. Movements were also categorized into 16 barcoding states, and we calculated the SampEn and proportions of the barcoding. All variables were compared between the two groups using independent-samples t-test or Mann-Whitney U test. The AR group had larger linear variability compared to the TD group. SampEn was lower in the AR group compared to TD group for both acceleration and angular velocity. Two barcoding states' proportions were significantly different between the two groups. The results showed that nonlinear analysis and barcoding could be used to identify the difference of dynamic multidimensional movement patterns between infants AR and infants with TD. This information may help early diagnosis of developmental disabilities in the future
