Real-time camera tracking is steadily gaining importance due to the drive from various applications, such as augmented reality, three-dimensional structure estimation/modeling, and mobile computing environment. However, tracking a monocular camera in an unknown environment is not a trivial work. We describe a real-time camera tracking framework designed to track a monocular camera in a workspace. In particular, we focus on integration of a bundle of nonlinear filters to achieve robust camera tracking and scalable feature mapping, which can extend to larger environment. The basic idea of the proposed framework is that a particle filter-based camera tracking is connected to independent feature tracking filters, which have fixed-state dimension. In addition, every estimate required for template prediction is obtained from the independent feature estimators so that the template prediction can be maintained without additional framework for the template state estimation. We split the camera tracking and feature mapping into two separate tasks, and they are handled in two parallel processes. We demonstrate the effectiveness of the proposed approach within a desktop environment in real time. © The Authors. Source

The spin-lattice relaxation time of the 1H nuclei in the ammonium groups in (NH 4) 2ZnCl 4 crystals has been measured as a function of temperature for a range of temperatures that includes those of the phase transitions. The temperature dependence of this relaxation time is more or less continuous near T C, and is not affected by the phase transitions. A minimum was found in the 1H spin-lattice relaxation time that is related to NH 4 + tunneling. Our results for (NH 4) 2ZnCl 4 are compared with previously reported results for Rb 2ZnCl 4 and Cs 2ZnCl 4 crystals. The differences between the atomic weights of NH 4, Rb, and Cs are responsible for the differences between the molecular motions and phase transitions of these single crystals. © 2011 Elsevier Inc.

Aim: This study examined the causal relation between spasticity, weakness, gross motor function, and functional outcome (expressed as activity limitation) in children with cerebral palsy (CP) and tested models of functional outcome mediated by gross motor function. Method: Eighty-one children (50 males, 31 females) with CP were recruited for this cross-sectional study. Their mean age was 10 years 4 months (SD 1y 9mo). Strength was assessed using the Manual Muscle Test. Spasticity was assessed by the Modified Ashworth Scale. The Gross Motor Function Measure assessed gross motor function. The Functional Skills domain of the Pediatric Evaluation of Disability Inventory assessed functional outcome. Twenty-eight children (34.6%) had quadriplegia, 44 children (54.3%) had diplegia, and nine children (11.1%) had hemiplegia. Children were classified using the Gross Motor Function Classification System with 14 (17.3%) in level I, 9 (11.1%) in level II, 13 (16.0%) in level III, 5 (6.2%) in level IV, and 40 (49.4%) in level V. Results: The proposed path model showed good fit indices. The direct effects were significant between spasticity and gross motor function (β=-0.339), between strength and gross motor function (β=0.447), and between gross motor function and functional outcome (β=0.708). Spasticity had a significant negative indirect effect (β=-0.240) and strength had a significant positive indirect effect (β=0.317) on functional outcome through effects on gross motor function. Interpretation: Activity-based rather than impairment-based intervention is more important for reducing activity limitation in children with CP. The study established a base from which researchers can further develop a causal model between motor impairments and functional outcome. © The Authors. Journal compilation © Mac Keith Press 2010.

Using a nonequilibrium Green's function method combined with density functional theory, we have calculated the quantum conductance of a recently synthesized μ-borolyl triple-decker sandwich complex, in which Ru and Co ions are sandwiched between three five-membered rings. The current-voltage characteristics of the complex when connected to Au (111) wire exhibit a strong nonlinear and asymmetric behavior at applied bias, in which multiple negative differential resistance (NDR) effects are observed. Our detailed analysis shows that the origin of the effect is quite diverse: this diversity can be attributed to the existence of a narrow bulk or surface electrode density of states and the alignment and misalignment of d-states of two metal ions. The substitution effect has been also investigated by replacing hydrogen atoms on the central ring with electronegative chlorine atoms. © 2010 American Chemical Society. Source

Problem-based learning (PBL) has been identified as an approach that improves the training of nurses by teaching them how to apply theory to clinical practice and by developing their problem-solving skills, which could be used to overcome environmental constraints within clinical practice. A consensus is emerging that there is a need for systematic reviews and meta-analyses regarding a range of selected topics in nursing education. The purpose of this study was to conduct a meta-analysis of the available literature in order to synthesize the effects of PBL in nursing education. Using a number of databases, we identified studies related to the effectiveness of PBL in nursing. An analysis was conducted on a range of outcome variables, including overall effect sizes and effects of evidence and evaluation levels, learning environment, and study characteristics. We found that the effect of PBL in nursing education is 0.70 standard deviations (medium-to-large effect size). We also found that PBL has positive effects on the outcome domains of satisfaction with training, clinical education, and skill course. These results may act as a guide for nurse educators with regard to the conditions under which PBL is more effective than traditional learning strategies. © 2012 Springer Science+Business Media Dordrecht.
