إن استقرار المنشآت الهندسية يعتبر المعيار الأساسي لأمانها مهما اختلفت عوامل الأمان (هيدرولوجية، مورفولوجية، جيولوجية، جيوديزية......) لكن الدراسة الجيوديزية (للتشوهات ) الأفقية و الشاقولية الحاصلة في المنشات الهندسية هي التي تعطي بشكل قاطع أمانها لأنها تستخدم التعبير الرقمي عن حالة أمان المنشأة. يهدف البحث إلى دراسة التشوهات الأفقية في سد الدويسات التابع لقرية الدويسات الواقعة في مدينة ادلب على الحدود السورية التركية. من اجل ذلك قمنا في المرحلة الأولى باستطلاع المنطقة و زراعة شبكة مراقبة أفقية و ارتفاعيه و من ثم مسحها طبوغرافيا بغية انجاز مخطط طبوغرافي لمنطقة الدراسة و في المرحلة الثانية : تم إجراء القياسات الحقلية الأفقية الدورية عبر فترات زمنية متباعدة و في نهاية كل دورة تم معالجة القياسات و حساب الإنزياحات الأفقية و تفسيرها. عن طريق برنامج تم تصميمه بلغة (فيجول بيزك) خصيصاً لذلك. و ختم البحث بأهم النتائج و التوصيات التي توصلت إليها الدراسة.
The stability of geometrical structure considered as the basic standard for it’s safety regardless of it’s different parameters (Hydrology, morphology ,geology and geodesy).But the geodetical study of the horizontal vertical (deforms) ultimately gives the safety because it uses the digital result about the construction safety. This research aims at studying the horizontal and vertical deforms of the ALDOYSAT werenear by ALDOYSAT village –Idleb- city-on the Syrian and Turkish border. For this reason in first step we surveyed the area installing topographic cally and acontrolling network to be able to achieving a topographical schema. In the next step: we did the periodical measurements throughout chronological times. At the end of every period we dealt the measurements and the shifts via visual basic program. The search was ended with the best results and recommendations.

Spatial organization of facilities depend on the analyzing of the
distribution of the networks of establishments and service centers in cities
with focus on the study of complementarity and comparability of the
place, place settlement (place distr
ibution and density), service areas,
wider access of shopping service, in addition to a good coordination
(administrative, technical and consumptive) forming the place service
construction. This should all lead in the end to the best geographic
distribution of the networks of facilities and service centers within a
comprehensive and complete system in cities at present and in the future.
Good geographical distribution of service location must reduce the
consumers' time and create the largest possible social and economic set of
activities. There must be justice in distribution, and equal access to the
services, in addition to satisfactory quality for the population in quantity
and variety, in a way that corresponds with the natural, social,
demographic, economic and constructive conditions of the place (like city
size, shape, functions, location, the population and their qualifications,
the opening times during which the city can provide the service to the residents, the percentage of service consumers and their class, the nature
of the organizing plan of the city and the use of the land there, the road
net, and means of transport and others.)
The establishments, service centers, facilities and the services are
distributed to suit in quantity and variety with the residential districts and
territories. The central part of the city contains most service activities,
because it forms the easiest way of getting transport, and this identifies
the great importance in place in organizing services in the city. The
smallest the city is, the better the access to services.
It is necessary here to distribute the service establishments among the
city quarters, regions, places of work, social and scientific centers, and
locations of access to means of transport. It must emerge from the
consumers' preferences and their interests, the state capacities, and the
constant need to develope the planning of residential services in the city
This research aimed to study some chemical characteristics of rainwater in the region
located at the East of Baniyas area the coastal region of Syria . Baniyas area contain
complex of industrial facilities including oil refinery, electrical power g
eneration station
and oil transportation. pH values, concentration of trace metals (Pb, Cu, and Cd) and major
ions (Ca2+, Mg 2⁺, Na⁺, NH₄⁺, K⁺,SO₄2-, NO3⁻, Cl⁻, F⁻) were determined during the period
from October 2012 to May 2013.
Samples were collected from 15 sites differ in distances from the emissions sources.
Most of samples have normal pH value. The pH values decreased while the concentration
of SO₄2-, NO3⁻, and trace metals Pb, Cu, Cd increased significantly by getting closer to
emission source up on 2500m. The changes of the chemical characteristics of rainwater
were significant.
Hierarchical multi-label text classification (HMTC) deals with the challenging task where an instance can be assigned to multiple hierarchically structured categories at the same time. The majority of prior studies either focus on reducing the HMTC t
ask into a flat multi-label problem ignoring the vertical category correlations or exploiting the dependencies across different hierarchical levels without considering the horizontal correlations among categories at the same level, which inevitably leads to fundamental information loss. In this paper, we propose a novel HMTC framework that considers both vertical and horizontal category correlations. Specifically, we first design a loosely coupled graph convolutional neural network as the representation extractor to obtain representations for words, documents, and, more importantly, level-wise representations for categories, which are not considered in previous works. Then, the learned category representations are adopted to capture the vertical dependencies among levels of category hierarchy and model the horizontal correlations. Finally, based on the document embeddings and category embeddings, we design a hybrid algorithm to predict the categories of the entire hierarchical structure. Extensive experiments conducted on real-world HMTC datasets validate the effectiveness of the proposed framework with significant improvements over the baselines.
The research aims to study the effect of weather (humidity - pressure - temperature) on
the linear measurements between geodesic network points through the introduction of
these factors directly on the Total station devices settings and get distanc
es patched for that
network has been based geodesic point (conducting field measurements necessary) within
easy reach of the design requirements of the device ideal conditions in the study area
(Trjano) in the province of Latakia, which we will adopt in the later stages to monitor
landslides and thus all measurement cycles will be compare basic measurement cycle
taking into account changes in ambient weather conditions in each measurement cycle for
the reference measurement cycle.
In this research we will examine the method of calculating azimuth and
latitude based on the parameters and mathematical equations for the
movement of the earth، stars and astronomical equipment.
