يجب أن تحقّق شبكات المراقبة الجيوديزية شروط الدقّة و الديمومة و القوّة و الحساسية و الكلفة. و على هذا الأساس يتم تصميم شبكات المراقبة الجيوديزية. تتحكم الأجهزة المساحية الأرضية الحديثة بالعمليات الحركية و بتردد عالي من القياسات، و بالتالي يمكن تحديد حالة النظام، و دقّته في الزمن الحقيقي وفقاً لنموذج التشوه المناسب. في هذا البحث، تمّ تقييم كفاءة مرشح كالمان الخطي في تحسين أداء شبكات المراقبة الجيوديزية خاصّةً المستخدمة حالياً في مراقبة المنشآت الاستراتيجية في القطر، و تحقيق أعلى مستوى من الأمان في مراقبتها و تطوير مستوى الموثوقية و المتانة فيها، و تطبيق ذلك على الحالة الحركية المرصودة لمنشأة سد 16 تشرين في محافظة اللاذقية. و من ثم التحقّق من كفاءة التقييم، بتطبيق معايير الموثوقية، و مدى ملاءمة تطبيق مرشح كالمان في تحليل التشوه. و قدّم البحث مجموعة من الاستنتاجات و التوصيات.
Geodetic monitoring networks should check the requirements of precision, stability, durability, strength, sensitivity and cost. Depending on this basis design the geodetic monitoring networks. Terrestrial surveying instruments adjust kinematic processes by high frequency measurements; therefore can select system state and its precision in real time depending on appropriate deformation model. In this research, liner kalman filter will be evaluated to improve the performance of geodetic monitoring networks, especially the currently used in monitoring of strategic infrastructure in the country, and achieve the highest level of security in the monitoring and development level of reliability and durability where, and apply it to the observed kinematic situation in 16 tishreen dam in lattakia city. Then check the efficiency of the evaluation by applied standards reliability, and the appropriateness of the application of kalman filter in deformation analysis. Finally, this research offers a set of conclusions and recommendations.

The objective of this research is to model the dynamic
characteristics of lead-acid batteries taking into account their
fundamental phenomena (the electric double-layer, the charge
transfer and diffusion phenomenon due to oxidation and reduction
reactions). The value of the equivalent circuit elements used in
modeling is determined experimentally using a pulsed discharge of
the battery.
Slow emerging topic detection is a task between event detection, where we aggregate behaviors of different words on short period of time, and language evolution, where we monitor their long term evolution. In this work, we tackle the problem of early
detection of slowly emerging new topics. To this end, we gather evidence of weak signals at the word level. We propose to monitor the behavior of words representation in an embedding space and use one of its geometrical properties to characterize the emergence of topics. As evaluation is typically hard for this kind of task, we present a framework for quantitative evaluation and show positive results that outperform state-of-the-art methods. Our method is evaluated on two public datasets of press and scientific articles.
In This study it has been uses a network for monitoring the pollution with organochlorine pesticides in There marine stations at Lattakia coast: Fishing port, AfamiaCoast, High Institute Of Marine Research Coastusing Cages contained species of musse
lswitch are filter feeders Brachidontes varibilis. Samples had been collected from Lattakia coast.
The results showed a great efficiency of the made network for monitoring the organic pollution in marine environment. It has been recorded a concentration of DDTs is accumulated lower than 2ng/g , Endosulfane and HCB is lower than 1 ng/g too. The results showed that the HCH compounds is dominant in all stations.organochlorine pesticides is accumulated mostly in the biota of station Fishing port, Afamia Coast
The environment is the effective framework in which man lives and interacts with him, and with the development of the human being and the growth and increase of his requirements, this led to various changes in the ecosystem, which can be positive or negative, and the need to reduce the negative impact of the change on the ecosystem and raise the level of the positive impact.
In this study, drought in the eastern region of Syria (Hasake, Rakka,
DerAzzor, Bokmal & Kameshli) has been investigated using SPI, NDVI
indices.
We used a set of data containing precipitation data for period from 1975 to 2010 to calculate Standardized Precipitation Index SPI, and MODIS time series images in April for period from 2000 to 2010 to calculate the Normalized Difference Vegetation Index NDVI.
