The current state of the seismic monitoring system in Kabardino-Balkaria

The processes of development of hydrocarbon deposits are accompanied, as a rule, by an increase in the level of seismicity and, in particular, by the occurrence of technogenic earthquakes and other deformation phenomena associated with changes in the geodynamic regime. To monitor deformation and geodynamic processes, a seismic monitoring service should be organized. A similar monitoring system is also required for the analysis of aftershock and volcanic activity. Monitoring technology should be based on the use of reliable and fast methods of automatic detection and localization of seismic events of various scales. Traditional approaches to the detection and localization of earthquake epicenters and hypocenters are based on the analysis of data recorded by one or more single seismic stations. In that case, seismic event coordinates are estimated by means of signal extraction from noise and accurately measuring arrival times of a number of specific phases of the seismic signal at each recording point. Existing computational techniques have inherited this traditional approach. However, automatic procedures based on the ideology of manual processing turn out to be extremely laborious and ineffective due to the complexity of algorithms adequate to the actions of an experienced geophysicist-interpreter. The article contains a description of new approaches to the synthesis of automatic monitoring systems, which are based on the principles of emission tomography, use of spatial registration systems, energy analysis of wave fields and methods of converting real waveforms into low-frequency model signals (so-called filter masks/templates). The monitoring system was successfully tested in the process of detecting and locating the epicenters and hypocenters of 19 weak local earthquakes in Israel, as well as a quarry explosion.

The reliability of busway in high current state is closely related to its temperature. So effectively monitoring temperature is the key issue to ensure the busway work safely. Because of the constraints such as high voltage and strong electromagnetic fields, traditional temperature measurement system can not meet the requirements. A distributed busway temperature monitoring system is designed in this paper based on the temperature effect of fiber Raman scattering signal. Arithmetic average, wavelet noise reduction and low-pass filter combination of data processing is used to overcome the very low SNR. Experiments show that the system can measure the temperature of 1km busway effectively. Temperature resolution can achieve 3°C.

Operative Measures

The UN Conference on Disarmament's Group of Scientific Experts (GSE) was established in 1976 to consider international co operative measures to detect and identify seismic events. Over the years, the GSE has developed and tested several concepts for an International Seismic Monitoring System (ISMS) for the purpose of assisting in the verification of a potential comprehensive test ban treaty. The GSE is now planning its third global technical test. (GSETT 3) in order to test new and revisled concepts for an ISMS. GSETT 3 wili be an unprecedented global effort to conduct an operationally realistic test of rapid collection, distribution and processing of seismie data. A global network of seismograph stations will provide data to an International Data Center, where the data will be processed an results made available to participants. The full scaIe phase of GSETT 3 is scheduled to begin in January 1995.

Solid Liquid Separation

Nowadays, since sewage disposal plant monitoring system is changed to combine automating control system tendency, automatic measurement method is widely applicable water temperature, pH, BOD, COD, suspended solid, etc. And its tendency is accumulated objective data. However, in the case of leaking suspended solid concentration measurement, it is literally not a long way from managing settling procedure. Because it has an effect on SS concentration of leaked water only when settled ability is disturbed. In other words, it means that research about solid-liquid separation activated sludge on automated monitoring system currently lacks, and needs research in this field. Considering that sedimentation process in the biological treatment process is one of the most important part, currently performed way, namely, SVI measured and judged by experienced specialists in standard procedure has weaknesses which objectivity cannot be guaranteed. Therefore, for maintaining the consistency of judging criteria and ensuring continuity of knowledge, objectified in the settling process is needed to build diagnostic systems. This paper proposed the method using image processing techniques over time due to settling of the sludge is analyzed for changes in height, also due to changes in sedimentation rate by analyzing the performance of the sludge settling, then send administrator for the system to pass the current state of the sludge.
