This paper presents the methods of designing a model to determine the appropriate points to build fire towers extended on an area of Syrian Arab Republic, in order to monitor and early warning the forest fire. This helps the authorities' process of
extinguishing the fire as it arises and thereby protect our forest from fire that destroys thousands of hectares every year.
The model has been designed using the tools of Spatial Analysis available in ArcGIS program. These tools have been applied to evaluate the performance of the fire towers in the studied area, and to suggest new sites for fire towers in this region in order
to increase the vision of the area. We calculate the area of visible areas covered by the suggested fire towers. We finally customize the parameters of the model to be applied for different areas using different input data, so the users of the model simply can enter the
parameters of their own area and apply the model.
This research includes designing and executing of an applied model for converting
the energy of the offshore sea waves into electrical power. The model runs according to
oscillating water column system (OWC) using air turbine, which rotates by the
air pressure
generated by the sea waves within the energy chamber.
The article studies the effect of technological changes on the efficiency of the model
and subsequently the number of its turbine's rotation, within the wave parameters under the
Syrian coast conditions. Results in form of clear curves and diagrams will be discussed.
They will also be analyzed and considered to achieve a suitable suggestion that can
improve the system in the future.
This paper presents the Change vector analysis (CVA) approach for detecting and
characterizing radiometric change in multispectral remote sensing data sets
The dynamic changes of the land use/land cover were studied in lattakia city by
using two E
TM-Landsat-7 scenes, for the years 2000, and 2010, and the spatial resolution
of those two images was 15 m. The CVA algorithm has been applied and produced two
‘channels’ of output change information multispectral change magnitude and change
vector direction in land use/land cover during this period. Two models have been built
within ERDAS Imagine 8.6 software to perform the algorithm and evaluate the positive
and negative changes and analyze the the human impacts on the land use/ land cover
change.
This method can be applied to various fields of study in order to generate maps
represent the continuous development of land use and land cover. These maps can be
significantly useful for the regional and urban planning and natural resource management,
in light of the great expansion of urban areas at the expense of green spaces and
uncontrolled use of the land.
The recent few decades have witnessed growing interest in the environment- friendly
energy sources. Sea Wave Energy is considered as one of the energy sources in the
countries that are located on the seas and oceans. However, this energy source, ga
ined little
interest in Syria compared to sun and wind sources. The aim of this research is to
contribute to the body of research in this field, by developing and implementing an
experimental model of an oscillating water column system, which converts sea wave
energy into electrical energy.
Additionally, the research uses a set of true and false experiments to study the impact
of the technological variables of the system on its efficiency, hence on the number of
rotation of its Wells turbine. The results were represented graphically, and
recommendations and suggestions were provided for the possibility to apply this
technology in Syria.
We introduce a taxonomic study of parallel programming models
on High-Performance architectures. We review the parallel
architectures(shared and distributed memory), and then the
development of the architectures through the emergence of the
heter
ogeneous and hybrid parallel architectures.
We review important parallel programming model as the
Partitioned Global Address Space (PGAS) model, as model for
distributed memory architectures and the Data Flow model as
model to heterogeneous and hybrid parallel programming. Finally
we present several scenarios for the use of this taxonomic study.
This research involves the study of collapse's possibility of Codana dam,
which is located on Al-Rakad valley in Quneitra governorate. The light had
been shed on: the concept of dam's collapse, forms of collapse slots by using
Hec-Ras program, Als
o it had been shown the reliable collapse scenarios and
choose the worst one when the access time of flood wave could be identified
for every cross-section.
After the analyzing of formation pressure data and pressure
interference tests between wells in Ash Shaer field, the field has
been divided initially into three main blocks, then a material
balance model has been built for the field using MBAL software.
This model has proved the previous result besides answering some
problems which hasn’t been solved by the analytical method.
