Temperature Prediction for Sun Synchronous Satellite on Orbit

Wei Chuanfeng,Li Yunze,Yuan Lingshuang,Wang Jun,Ning Xianwen

Strategic Study of CAE 2005, Volume 7, Issue 2,   Pages 73-75

Abstract:

Temperature prediction on-line for sun synchronous satellite is very essential. In this paper, satellite's temperature is predicted on-line after the analysis to the cycles of orbital external thermal current and average temperature. Temperature distribution predicted by last two circles can be the basis on thermal fault diagnosis for satellites. Meanwhile the error accumulation can be avoided. Fly experiment data show that the method is reliable.

Experimental determination of Cd

Farhah Amalya ISMAIL, Ahmad Zaharin ARIS

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 3,   Pages 356-364 doi: 10.1007/s11783-013-0488-1

Abstract: Carbonate shells have an astonishing ability in the removal of Cd in a short time period with emphasis on being a low cost adsorbent. In the present study, the sorption capacity of carbonate shells was studied for Cd in batch experiments. The influence of different carbonate shell sizes and physico-chemical factors were evaluated and the results were analyzed for its correlation matrices by using Predictive Analytics Software (PASW). The mineralogy state of aqueous solution regarding the saturation index was simulated using PHREEQC to identify the Cd uptake mechanism. The Cd uptake rates were calculated as well as Ca , concentration, pH, ambient humidity and temperature were measured. Cd removal of 91.52% was achieved after 5 h adsorption. The adsorption efficiencies were significantly influenced by pH as they increased with the increase of pH from acidic solution (5.50±0.02) to slightly alkaline (7.60±0.05). In addition, the mineralogy state of aqueous solution calculated from PHREEQC confirmed that the increment of Ca and concentrations in solution was attributed to the dissolution of carbonate shells. Moreover, the ion exchange adsorption mechanism of Cd toward Ca was identified as the process involved in Cd uptake.
