تطورت في السنوات الأخيرة طريقتا تحليل متعدد القنوات للأمواج السطحية (MASW) النشطة و الانكسارية الدقيقة (ReMi) لتحديد السرعة الوسطية للأمواج العرضية للطبقات السطحية لعمق 30 م (Vs30) الذي يستخدم في تصنيف المواقع و دراسات التمنطق الزلزالي في المناطق الحضرية للحد من المخاطر الزلزالية. يظهر البحث فائدة استخدام الطريقة الانكسارية الدقيقة و أهميتها في دراسة طبقات التربة العميقة التي قد يصل عمقها إلى أكثر من 30 م في مدينة إربد (الأردن)، الواقعة شرق نظام صدع البحر الميت التحويلي بنحو 25 كم.
In the last few years the Active Multichannel Analysis of Surface Waves (MASW) and Refraction Microtremor (ReMi) methods were developed to determine average shear wave velocity of the upper surface layers (Vs30) which is used for site classification and seismic microzonation studies of urban areas to reduce earthquake risks. This research showed the usefulness and importance of the use of ReMi method to study the deep soil layers which may reach a depth of more than 30 m in the city of Irbid (Jordan), located 25 km east of the Dead Sea Transform (DST) fault system.

The research had been implemented in Daher Al Kheribat stand in Jableh area in
Syria in 2014- 2015 with the aim to inventory and characterize the herbal vegetation cover.
Four sites were chosen in the stand. We adopted Parker method to estimate the
plant
coverage and relative coverage, and the method of squares was adopted to estimate the
intensity and frequency. Plant samples were collected from the stand and dried and then
classified based on Flora available. 42 species were registered belonging to 35 genuses
distributed in 16 families. The number of plant species palatable was higher than the
number of plant species unpalatable. Bromus squarrosus L. recorded the highest relative
importance (28.3%), followed by Alopecurus urticulatus Banks & Sol (15.1%) then
Euphorbia helioscopia L. (9.0%), The Bromus squarrosus L plant and the Alopecurus
urticulatus Banks & Sol are good pastoral while the Euphorbia helioscopia L. plant is
worthless pastoral.
Most of the electronic money that has been developed so far to meet certain
functions and say that they replaced the money traditional is wrong despite huge
advances in the forms of electronic payment but the money still have traditional
keep its
place special handling, especially in large deals that need to be degree
significant protection.
Therefore we can say that there is a significant shift in the monetary sphere is
happening today in the world, despite the recent this transformation but it could be
argued that the accelerations shall that have occurred in the area of the digital
revolution has opened the way for radical shift in the pattern of trade and
international exchange in line with globalization, which is dominated on all branches
of activities, especially in areas relating to how the exchange of goods and settlement
of obligations...
In natural language generation tasks, a neural language model is used for generating a sequence of words forming a sentence. The topmost weight matrix of the language model, known as the classification layer, can be viewed as a set of vectors, each r
epresenting a target word from the target dictionary. The target word vectors, along with the rest of the model parameters, are learned and updated during training. In this paper, we analyze the properties encoded in the target vectors and question the necessity of learning these vectors. We suggest to randomly draw the target vectors and set them as fixed so that no weights updates are being made during training. We show that by excluding the vectors from the optimization, the number of parameters drastically decreases with a marginal effect on the performance. We demonstrate the effectiveness of our method in image-captioning and machine-translation.
In this research, the changes on these seeds during storage:
total oil, volatile oil, and the major components of volatile oils were
determined. A decrease in the total and volatile oils and all
components of volatile oils were found.
Novel rejected and passed band devices are obtained using
techniques in two dimensional Photonic Band Gap microstrip
structures. The microstrip is engraved in a PBG dielectric
constituted of a via holes array and enclosed in a metallic box. The
b
oundary element method (BEM) and the fast wave concept
iterative process (FWCIP) are combined to evaluate the
characteristic of this structure.
