Deadwood is a large global carbon store with its size partially determined by biotic decay. Microbial wood decay rates are known to respond changing temperature and precipitation. Termites also important decomposers in the tropics but less well studied. An understanding of their climate sensitivities needed estimate change effects on pools. Using data from 133 sites spanning six continents, we found that termite discovery consumption were highly sensitive (with increasing >6.8 times per 10°C...
This paper describes software system for a humanoid robot viewed from motion generation aspect by taking kitchen helping behaviors as an example of real world task. Our consists high level reasoning modules including 3D geometric model based action/motion planner and runtime contains visual processor, force manipulation controller walking controller. We discuss how action functions contribute to various tasks role perception using vision sensor sensors.
In this paper, we describe a planner for humanoid robot that is capable of finding path in an environment with movable objects, whereas previous motion only deals fixed objects. We address manipulation problem finds walking from the given start location to goal while displacing obstructing objects on path. This requires more complex configuration space than researches using mobile especially phase, since has many degrees freedom its arm forklift type robot. Our approach build task graph...
Abstract Ectomycorrhizal (ECM) fungi are functionally important in biogeochemical cycles tropical ecosystems. Extracellular enzymatic activity of ECM on a ground-area basis is the product two attributes; exploration capacity (ECM surface-area) and specific activity. Here, we elucidated which attribute better explained response to different levels soil phosphorus (P) Nitrogen (N) availability five Bornean rainforests. We determined surface area root tips as well activities per for carbon (C),...
This paper describes vision-based 3D walking system of a humanoid robot by combining precise planar surface detection method and practical footstep planner method. The control requires vision with 10[mm] accuracy. Then we developed the recognition Hough transformation robust estimation We also foot step considering kinematics dynamics restriction hardware. Finally, realized based experiments that steps upon an unknown obstacle are shown.
To evaluate the effects of newly developed nitroglycerine (NTG) tape on peripheral circulatory disturbance in systemic sclerosis (SSc).The finger temperature (FT) 25 patients with SSc was monitored by thermography before application NTG to wrist and one hour afterwards. check placebo effect, change FT six who had shown a distinct rise (>2 degrees C) monitored.Twenty low (colder than mean-2SD normal controls). significantly raised after (p<0.01). Patients showed more often (71% v 0%, p<0.01)....
This paper describes the design and development of system software for humanoid robots such that researchers who specialize not only in biped walking but also various fields are able to use as a research tool. For this purpose, must integrate organize each subsystem control, recognition, dialogue, planning so on, it provide efficient full-body motion control by specifying fewer degrees freedom than all joints. Our provides common interface among subsystems implementing function method call...
In order for humanoids to imitate humans behavior, it is important extract a needful parameter target of imitation. Especially in daily-life environment, only simple joint angles are insufficiency because position and posture hands remarkable point object needed intent this paper, we describe development methods motion capturing system with interactive teaching task attention, show its feasibility environments.
This paper describes daily assistive task experiments that conducting on the HRP2JSK humanoid robot. We present overall action and recognition integrated system design to realize behaviors autonomously robustly, along with demonstration pours tea from a bottle cup wash it after human drink it. To obtain autonomy robustness, visual behavior control through perception information are important.
In this paper, we propose a new approach for humanoid balance control. previous research, control of was regarded as method which absorbs the difference assumed environment model and real environment. contrast, focus on generating bracing motions using prediction time series external force. We introduce disturbance preview to generate behavior against impact. order reduce ZMP error at moment impact, desired COG trajectory by that takes future information an force represented velocity COG....
In this paper, we treat with wheelchair support by a life-sized humanoid robot. It is quite essential to integrate whole-body motion, recognition of environment and human-interface behind the user in order achieve task. Contributions paper control including pushing motion using offset ZMP observation attitude outlier, particle filter person face detection gesture.
Abstract The ENDOR spectra of diphenyl nitroxide (DPNO) and its monomethyl derivatives were observed in ethylbenzene at −70 °C. agreement between the ESR data is generally good. MO calculations, however, indicate a few disagreements case m- o-methyl DPNO derivatives. methyl substitution meta-position destroys equivalency all protons meta-positions, which are divided into two sets equivalent proton groups same number. ortho-substitution weakens coplanarity benzene rings increases number...
Abstract: Plant communities and ecosystem processes in seres at multiple altitudes the tropical montane forest zone of northern Borneo were studied to understand patterns mechanisms secondary succession after shifting cultivation. A total 25 stands (and additional three stands) sampled with stand ages ranging from 2 55 y slash burn between 900 1400 m asl. species composition, above-ground biomass (AGB), chemical properties soils, litter foliar samples investigated each stand. TWINSPAN...
This paper presents a method to generate vision and task based robot manipulator trajectories. In the framework of research on daily assistive robots formulated for this work consists in ranging boxes shelf or picking them up placing into shopping cart. For object recovery SIFT keypoint tracking combination with stereo is used. A collision free trajectory between two way points generated 3D-gridmap environment front robot. generation loop implemented using resolved motion rate control...
SummarySeedling storage can help to match supply with demand. To develop a method preserve the quality of stored cabbage (Brassica oleracea L.) plug seedlings, we investigated effects duration daily red light-emitting diode (LED) illumination during on shoot growth, carbohydrate concentrations, and photosynthetic characteristics. Seedlings were at 10ºC for 3 weeks in dark or under LED photon flux density 0.8 µmol m–2 s–1 5, 20, 60, 240, 1,440 min (continuous light) d–1. Shoots elongated...
Tropical countries are now facing increasing global pressure to conserve tropical forests, while having maintain cultivated lands (particularly shifting cultivation) for the subsistence of local people. To accomplish effective conservation forests in harmony with cultivation, we evaluated influence cultivation on ecosystem services (i.e., biodiversity and carbon stock) at a landscape level based three land-use scenarios. The study focus was upland area between Kinabalu Park Crocker Range...
