Information of temperature and humidity in planting media is very important for cultivation activities and  the process of plant growth, where the real time process is very useful to determine the watering process on planting media. The purpose of the research that has been done was to design a monitoring system for soil temperature and humidity on the planting media and to make an automatic plant watering sprinkler by detecting soil moisture. A design for monitoring soil temperature and humidity on planting media has been made with a microcontroller. This instrument works when the pump detects soil with a range ​​from 0-3 cm/Hg for dry, 3.1-6 cm/Hg for moist and 6-7.9 cm/Hg for wet. When the soil is dry, the pump will work by removing water and stop when the soil is damp or wet.

Turbopump is a high-fault-rate component in Liquid Rocket Engine (LRE). The research on real-time process monitoring technology and system for turbopump is vital to increase the reliability and safety of LRE. In this paper, three real-time process monitoring algorithms for turbopump were studied firstly, on the basis of monitoring parameters selection and multiple domain feature extraction. Then, the real-time monitoring system realized by means of PXI (PCI eXtensions for Instrumentation) controller was introduced. And, aiming at the shortage of the previous system, the real-time process monitoring system based on DSP (Digital Signal Processor) for turbopump was studied to realize higher computing speed, which could conduce to extract multiple domain features and run manifold real-time monitoring algorithms. The new system could also satisfy the small-sized requirement in engine flying state.

Abstract Monitoring of environment parameter such as soil moisture, temperature and humidity are important parts of plant growth. This paper focused on the development of an instrumentation system and analysis on the effect of the water volume to the soil moisture, effect rate of soil moisture, temperature and humidity for an indoor greenhouse. Data were collected through two experiment. First experiment focused on effect volume of water to soil moisture. Soil hygrometer sensor used to measure soil moisture in real time. Five bottles contained different volume of water poured into soil which the soil is fixed to 200gram.Three different rate of soil moisture applied to plant and the data were analysed to determined relationship between soil moisture to the plant growth. It can be concluded that the rate of soil moisture does have effect on the stem diameter and leaves length based on the observations of the plant growth for three weeks.

Monitoring Platform

To solve the difficulty of traditional video monitoring system in system upgrade and expansion, an solution of embedded video monitoring system based on DaVinci technology was put forward in this paper. By building the monitoring platform by DM6437 and DSP/BIOS in the solution, TVP5151 was used for receiving video signal in PAL/NTSC formats, and an JPEG Baseline Profile Encoder was integrated for video encoding, and the 10/100M Ethernet transmission function was realized based on NDK. Finally, the system is tested and the result shows that the system can capture and transmit D1 format signal in 25f/s and met the real-time requirement. At the same time, the system is easy to use and expand with a bright application prospect.

Shaft Lining

Shaft linings in thick weakly cemented stratum have the disadvantages of large deformation and repeated damage after repair. Considering the typical geologic characteristics and the failure characteristics of shaft linings, we establish a multilayer automatic deformation monitoring system in this paper, and the monitoring system can realize the real-time, continuous, and long-term dynamic monitoring on shaft linings. Based on the concrete strength failure criterion under biaxial compression and the analytical solution for spatially axisymmetric problem of thick-wall cylinders, the damage limit of the shaft lining in Xieqiao coal mine is obtained. Then, we choose three sections as the test area according to the typical damage forms of shaft linings to carry out the monitoring scheme on the auxiliary shaft in Xieqiao coal mine. The monitoring results show that the extreme value of the shaft lining deformation is 2.369 mm. And the shaft lining located in the border between the floor aquifer and the bedrock generates the most severe deformation, which is about 89.4% of the deformation limit. The shaft lining deformation increment fluctuates in certain range, which belongs to elastic deformation. Finally, we inverse the stress state according to the deformation value of the shaft lining, and the obtained additional stress is found to be lower than the ultimate compressive strength. Long-term project practice confirms that the deformation monitoring results can reflect the real stress condition of the shaft lining and that the monitoring system can realize the real-time dynamic evaluation for the status of the shaft lining.

This article introduces the reader to the considerations that had to be taken when cleaning and refreshing two of its large display cases at the Jewish Museum of Greece. Those display cases contain a mixed collection of variable items namely costumes, photographs, prints and wa-tercolours. The staff of the museum planned in advance, ensuring the safety of the objects and staff. Eventually it is natural for unpredicted problems to occur in the real time process. The Museum acknowledged the convenience of the visitor pathway and, moreover, granted visual access to the treatment actions by encouraging communication with the working staff, enriching the visitor experience. Finally the process was beneficial for evaluating the staff's teamwork and the production of a record, and a methodology to be followed for other display cases of the museum and potentially by other institutions.
