تشكل قواعد البيانات الصوتية حجر الأساس في بناء نظم النطق الآلي و التعرف الآلي على الكلام و على المتكلم باختلاف اللغات و اللهجات، و تكون عناصر قاعدة البيانات الصوتية عادةً ملفات صوتية سبق أن سجلت لأصوات أشخاص باللغة أو اللهجة المطلوبة، و كلما ذخرت قاعدة البيانات الصوتية بعناصر شاملة كلما أسهم ذلك في إنتاج أنظمة تخاطب مع الآلة ذات أداء متميز. و نظراً لعدم توفر قاعدة بيانات صوتية للهجات السورية؛ تمَّ في البحث بإنشاء قاعدة بيانات للصوتيات السورية، ضمت ستة عشر متطوع و متطوعة من مناطق سورية مختلفة اللهجة سُجلت أصواتهم في ظروف تسجيل مختلفة؛ و ذلك لدراسة تأثير تنوع اللهجات و اختلاف الجنس و ظروف التسجيل على مساحات المضلعات الصوتية. استثمر هذا البحث قاعدة البيانات الصوتية المُنجزة في مجال توليد و تحليل مضلعات الصوتيات السورية، و بالتالي تمَّ الحصول 64 مضلع صوتي تعود إلى 16 متحدث،حيث أن المضلع الصوتي هو مضلع هندسي رؤوسه تمثل قيم ترددات توافقيات المجرى الصوتي الممتد من الحبال الصوتية إلى الشفاه و تسمى النغمات ((Formants، و مساحة المضلع الصوتي الناتج تمثل مساحة المجال الصوتي.
Speech databases form the main foundation in the construction of automatic utterance, speaker recognition and speech recognition systems in different languages and dialects. The elements of the speech database are audio files recorded for people's voices in the required language or dialect. The more the speech database is enriched with comprehensive elements the more it contributes to produce systems that communicate with the excellent performed machine. According to the lack of speech databases for the Syrian dialects, the research did one. The created database contained sixteen voluntaries from different Syrian dialects. Voluntaries' voices were recorded in different recording conditions that is for studying the effect of variety of dialects, gender and the conditions of recording on the vowel polygons. This research invested the created speech database in the field of generating and analyzing of vowel polygons, as the vowel polygon is a geometric polygon where its vertices represent the values of formant frequencies, and the area of the polygon represents the output acoustic space.

In this research, a new comparison criterion was proposed to study properties of the
audio signal for each of the varieties of smokers and non-smoking persons. For this
purpose, a database for smokers has been created. The smoker database contains
12 Syrian
native speakers, six of them were smokers and the others were non-smokers. The smokers
had been smoking for more than 10 years. All speakers were men and their ages ranging
between 35 and 42 years old. They live in rural towns and speak the same dialect.
Syrian vowels can be classified into long vowels and short ones. The long vowels are
/AA/, /UU/, /II/ pronounced as ([ ي, و, ا ]) and the short vowels are /A/, /U/, /I/ pronounced
as ([ كسرة, ضمة, فتحة ]). In this study, the Speakers have to pronounce the following sentence
/I love Syria/ pronounced as ([ أَنَاْ أَحَبُّ سُوْرِيْة ]), and it was spoken during three hours. This
sentence is rich with vowels.
For each speaker, a long vowel triangle in ten planes and a short vowel triangle in ten
planes as well were generated and analyzed. A new criterion was suggested to determine
the most suitable vowel triangle for smoker distinction. This criterion depends on
calculating the different distances among all centers of vowel triangles in each plane and
determining the minimal distance called d. For each plane, the most suitable vowel triangle
had been set as AIU35 short vowel triangle and AAIIUU45 long vowel triangle.

This paper presents a method integrating database with Jgroup
based on Hibernate, which is one of Object Relational Mapping
tools. We compare between the performance of Jgroup integrated
with Hibernate and the performance of RMI integrated with
Hibernate. The results show that Jgroup/Hibernate outperforms
RMI/Hibernate when the number of clients increases.
The research aims to study how to add new components to Multisim database. Or
how to model a component using the programing language C++ , to use this new
component later in designing and making electronic circuits and devices.
Multisim has built-
in models for most types of devices, , the study aims to lay the
foundations and method for modeling of electronic items which is not located within the
Multisim program database, (or present with different values) , and that we need while
using this program in the modeling and simulation process for a given circuit.
Code modeling method has been proposed to reach this goal; this method relies on
the behavior of the device or the modeled component.
The study shows how to create a Code model for a specific capacitor that has
different values to those existing within the database and add to it.
Most of the contracting companies suffer from poor coordination between the projects that they implement at the same time, and in Shauria, the situation is getting worse due to the absence of the application of modern methodologies in project managem
ent, which causes a great waste of time and effort, especially for organizing and retrieving dozens of documents related to planning and follow-up, and consequently an increase in time, cost and poor quality.
