In this article we present a new method for automatic landmark extraction from the contours of biological specimens. Our ultimate goal is to enable automatic identification of biological specimens in photographs and drawings held in a database. We propose to use Active Appearance Models for visual indexing of both photographs and drawings. Automatic landmark extraction will assist us in buildin...

With the emergence of the Internet, collaborative computing has become more feasible than ever. Organizations can share valuable information among each other. However, certain users should only access certain portions of source data. The CHAOS (Configurable Heterogeneous Active Object System) project addresses security issues that arise when information is shared among collaborating enterprises...

Introduction: The Iranian Brain Imaging Database (IBID) was initiated in 2017, with 5 major goals: provide researchers easy access to a neuroimaging database, provide normative quantitative measures of the brain for clinical research purposes, study the aging profile of the brain, examine the association of brain structure and function, and join the ENIGMA consortium. Many prestigious databases...

Active-databases are a budding technology where rule-based expert systems can be developed in tight integration with database management systems. This paper presents VenusIDS: an active database component of the Network Exploitation Detection Analyst Assistant (NEDAA) developed as an enhancement to the analysis layer of a two-layer distributed network intrusion detection system using the VenusD...

Traditional database security is made more complex by the addition of rules to the data model. The security policy must control access privileges and accessibility for rule descriptions, executing rules, and database transitions (events). In this paper we extend the multilevel secure relational model to capture the functionality required of an active database, i. e. a database with production r...

The event-condition-action paradigm (also known as triggers or rules) gives a database “active” capabilities – the ability to react automatically to changes in the database or in the environment. One potential use of this technology is in the area of multilevel secure (MLS) data processing, such as, military, where the subjects and objects are classified into different security levels and manda...

As an alternative to the existing software architectures that underpin the development of smart homes and ambient assisted living (AAL) systems, this work presents a database-centric architecture that takes advantage of active databases and in-database processing. Current platforms supporting AAL systems use database management systems (DBMSs) exclusively for data storage. Active databases empl...

Current needs of industry required the development of advanced database models like active mobile database systems. An active mobile database system can be designed by incorporation of triggering rules into a mobile computing environment in which the users are able to access a collection of database services using mobile and non-mobile computers at any location. Fuzzy concepts are adapted to th...

This paper introduces a visual language for active database systems. We present a new approach to database programming based on visual active language that allows us to describe active rules in a graphical way. The resulting visual language can be transformed into a textual one. In addition, an active system can be represented with several di erent graphs showing the interactions of rules and t...
