يهدف البحث إلى دراسة إمكانية استخدام التسوية الغير مباشرة للمسالك الأرضية حصرا في إيجاد مناسيب المراصد الأرضية ضمن أعمال المرحلة الأولى من المسح الطبوغرافي للتجمعات السكانية بدلا" من التسوية المباشرة الكلاسيكية المطلوبة في دفتر الشروط الفنية – الصادر عن مديرية الطبوغرافيا – دمشق.
The research aims to study the possibility of using nondirect leveling to the paths of the earth to find the heights of ground traverses observatories within the works of the first phase of the topographic survey rather than direct leveling.

We create a large-scale dialogue corpus that provides pragmatic paraphrases to advance technology for understanding the underlying intentions of users. While neural conversation models acquire the ability to generate fluent responses through training
on a dialogue corpus, previous corpora have mainly focused on the literal meanings of utterances. However, in reality, people do not always present their intentions directly. For example, if a person said to the operator of a reservation service I don't have enough budget.'', they, in fact, mean please find a cheaper option for me.'' Our corpus provides a total of 71,498 indirect--direct utterance pairs accompanied by a multi-turn dialogue history extracted from the MultiWoZ dataset. In addition, we propose three tasks to benchmark the ability of models to recognize and generate indirect and direct utterances. We also investigated the performance of state-of-the-art pre-trained models as baselines.
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.
In this paper, we
describe an algorithm to register the retinal images by employing a relatively
cross-correlation function. Pixel to pixel accuracy has been investigated and
evaluated among registered images by calculating the local cross-correla
tion
between extracted vessels profiles along tracked vessels after transforming
the images into alignment.
This research was carried out in five sites varied in altitude representing Mediterranean vegetation zones of western slopes of Lattakia Mountains during 2010 - 2011 on Quercus infectoria Oliv species. Research shows that significant difference of al
titude above sea level has obvious effect on seed germination in different sites. This is noticed in characteristics related to fruit weight, germination rate value sum, and height of vegetal and rooty seedling after four months of germination. Altitude above sea level has no effect on the branchlet number of rooty and vegetal sum height of seedlings as well as mean of leaves number of seedlings. According to germination ratio and daily germination ratio, in addition to seedling diameter, there is harmony among all sites. It can be deduced that there are changes in growth traits of studied seedlings in different sites. This is the primary indication of the impact of the altitude above sea level on seedling traits of Quercus infectoria Oliv.
نريد في هذا المشروع تصميم نظام اتصال الطيف الدنثور بالسلسلة المباشرة اعتماداً على تقنية
الهوائيات المتعددة، بحيث نستطيع تحسين مواصفات النظام من حيث: المناعة ضد الضجيج و التشويش،
و خفض استطاعة الاتصال بتقنية DSSS عند الاعتماد على تقنيات ال MIMO بالم
قارنة مع الأنظمة
ذات الهوائي الوحيد في كل من الإرسال و الاستقبال SISO ، و ذلك ضمن بيئة خفوت ريليه مسطح و
بطيء.
