ظهر خلال نصف القرن المنصرم العديد من تطبيقات قواعد المعطيات التي يؤدي الوقت فيها دوراً مهماً، فكشفت عن نقص في دعم الدلالات الزمنية ضمن نظم إدارة قواعد المعطيات الحالية، إِذ يقع على عاتق التطبيقات الزمنية إعطاء البيانات دلالات زمنية مرتبطة بها، و التحقق من القيود الزمنية لضمان الاتساق، لذلك اتجهت البحوث إلى تضمين هذه الدلالات و القيود الزمنية في نظام إدارة قواعد المعطيات نفسه، و توفير لغة استعلام جديدة مناسبة توصف بأنها زمنية.
There was within the last 50 years a lot of database applications in which time plays an important role. These applications revealed a lack in time support within the current DBMSs as the application should give the data the temporal semantics related to it, also to check the temporal constraints. Therefore, researches were made in order to embed this temporal semantics and constraints in the DBMS itself, also to provide a new query language that can be tagged as “temporal”.

This researchdeals with the topic of controlling the cost of concrete bridge projects in
the early design phase. The research aims at using cost controlling as an auxiliary tool for
designing and decision making.Cost control methodology has been pr
oposed based on
modeling the elements of structure, and proposing a method forcost estimate. This method
based on estimating of quantitiesfrom the general parameters of the structure and prices are
being updated periodically.The proposed methodology studiesmany available alternatives
that werechosen by the designer andevaluate thesealternativeseconomically.
The intent of this paper is to present a novel quantitative equation to assess information
security level for enterprises, establishments and corporate generally, and financial institutions
specifically in public and private sectors in Syria. This
method is the result of statistical study1
which has been applied to a set of financial institutions in Syria as a sample of study to assess the
gap between existing information security level and ISO 27K directives for Information and
Communication Technology (ICT) security, benefiting from other international approaches and
models designed for this purpose.
This study aims to highlight the special requirements and the modified framework required to
develop ICT security in financial institutions taking into consideration the culture and the
special conditions in Syria.
This paper presents an automated system to continuously monitor and
control pollution levels of different types of pollutants in industrial plants.
Steel producing complexes are considered in this paper to represent an
example of industrial plants
. The proposed system consists mainly of two
major parts; the pollution measuring equipment and the automation system.
The measuring devices are sensors, actuators, etc., located at the potential
sources of pollutants such as dusts, stacks and chemical processes.
Performance of neural models for named entity recognition degrades over time, becoming stale. This degradation is due to temporal drift, the change in our target variables' statistical properties over time. This issue is especially problematic for so
cial media data, where topics change rapidly. In order to mitigate the problem, data annotation and retraining of models is common. Despite its usefulness, this process is expensive and time-consuming, which motivates new research on efficient model updating. In this paper, we propose an intuitive approach to measure the potential trendiness of tweets and use this metric to select the most informative instances to use for training. We conduct experiments on three state-of-the-art models on the Temporal Twitter Dataset. Our approach shows larger increases in prediction accuracy with less training data than the alternatives, making it an attractive, practical solution.
Reliable tagging of Temporal Expressions (TEs, e.g., Book a table at L'Osteria for Sunday evening) is a central requirement for Voice Assistants (VAs). However, there is a dearth of resources and systems for the VA domain, since publicly-available te
mporal taggers are trained only on substantially different domains, such as news and clinical text. Since the cost of annotating large datasets is prohibitive, we investigate the trade-off between in-domain data and performance in DA-Time, a hybrid temporal tagger for the English VA domain which combines a neural architecture for robust TE recognition, with a parser-based TE normalizer. We find that transfer learning goes a long way even with as little as 25 in-domain sentences: DA-Time performs at the state of the art on the news domain, and substantially outperforms it on the VA domain.
