  • Cooperative localization for multi-robot incorporating proprioceptive/ exteroceptive position sensors
    Springer Tracts in Advanced Robotics, 2008
    Co-Authors: Jihong Lee, Kyounghwan Jo, Choulsoo Jang
    Abstract:

    This paper presents a new method of cooperative localization for mul- tiple robots utilizing correlation between GPS errors of common mode in shared workspace. Assuming that GPS data of individual robot are correlated strongly as the distance between robots are close, we utilize the differential position data be- tween the robots to refine robot’s position data. Under Artificial Environment for simulation with imposed model error to robot motion and GPS sensor data error, it is confirmed that the proposed method provides improved localization accuracy [9]. In addition, we present a practical solution to accumulated position error in traveling long distance.

  • experimental study on an indoor scale solar chimney setup in an Artificial Environment simulation laboratory
    Applied Thermal Engineering, 2016
    Co-Authors: Yuan Wang, Qinglong Meng, Jingyin Li
    Abstract:

    Abstract An Artificial Environment simulation laboratory (AESL) was built and successfully applied to the experimental study of a solar chimney setup for the first time. A solar simulator and a temperature control system are included in the laboratory to achieve active control of Environmental parameters. An indoor scale solar chimney setup with a collector diameter of 1.22 m and chimney height of 1 m was constructed in the testing area of the AESL. The airflow temperature and updraft velocity were measured for the solar chimney setup with varying radiation intensities and chimney heights. The measured data were used to validate a thermal model for the collector. The thermal characteristics of the solar collector were investigated through the temperature field in the collector. The upper limitations on the collector radius and chimney height were discussed based on experimental results. The experimental work on the basic solar chimney setup performance helped in understanding the thermodynamic characteristics of the solar chimney power plant (SCPP), thereby serving as the basis for the design of large-scale commercial SCPPs.

  • MODEL KEHIDUPAN ZOOXANTHELLAE DAN PENUMBUHAN MASSALNYA PADA MEDIA BINAAN Zooxanthellae Life Model and Massalization Growth in the Artificial Environment Waters
    2020
    Co-Authors: Pujiono Wahyu Purnomo, Dedi Soedharma, Neviaty P. Zamani, Harpasis S. Sanusi, Sekolah Pascasarjana
    Abstract:

    Zooxanthellae are part of the phototropic dinoflagellates. This organism always live as symbiotically with several marine invertebrates. Relationship between zooxanthellae and coral are mutualistic with the transfer nutritif and phisiologis character. With this character, no coral can live without zooxanthellae. Zooxanthellae have vital control on the coral and sessile life. Model of relationship between zooxanthellae and coral are adopted in the Artificial Environment for take the massalization culture zooxanthellae in the Artificial Environment. This study was purposed to : (a) Evaluating of Environment limiting factors to support optimum growth of zooxanthellae in the Artificial Environment; (b) Evaluating of purification culture of zooxanthellae and (c) Formulating nutritif to maintenance of maximum gorwth of zooxanthellae. The experiment took place in Natural food and Genetic laboratory of Main Centre of Brackishwater Aquaculture Development Jepara from August 2004 to September 2005. The result showed that: (a) The optimum irradiance for growth of zooxanthellae is green radiance (with comparison 490 - 550 nm); (b) The optimum temperature for growth of zooxanthellae are 20 - 25 o C and (c) Adding of 200 µM NaNO3 with repeat again for 16 days,
