Security on mobile phones with lightweight cryptographic message syntax

By admin

Cryptographic Message Syntax (CMS) is a standard for protecting messages
cryptographically. Using CMS, messages can be protected in different content types
such as signed-data, enveloped-data, digested-data and authenticated-data. CMS is
architected around certificate based key management and symmetric cryptography.
In this thesis, a lightweight CMS envelope is proposed for the mobile phones which
have limited memory and processing power, in [...]

Feature-based software asset modeling with domain specific kits

By admin

This study proposes an industrialization model, Software Factory Automation, for
establishing software product lines. Major contributions of this thesis are the conceptualization
of Domain Specific Kits (DSKs) and a domain design model for software
product lines based on DSKs. The concept of DSK has been inspired by the way other
industries have been successfully realizing factory automation for decades. [...]

Semantic processes for constructing composite Web services

By admin

In Web service composition, service discovery and combining suitable services through
determination of interoperability among different services are important operations. Utilizing
semantics improves the quality and facilitates automation of these operations. There are
several previous approaches for semantic service discovery and service matching. In this
work, we exploit and extend these semantic approaches in order to make Web service
composition [...]

The implementation of a multimedia data mining tool

By admin

sophisticated. A lightweight tool that provides an easy to use environment for the
students who are learning data mining and multimedia is beneficial for their education.
In this thesis, we developed a tool that provides a simple interface for image
processing and a way to running data mining algorithms on image files which will be quite
valuable in data [...]

Architecture specification of service-oriented systems through semantic Web technologies

By admin

This thesis presents a semantic-based modeling approach for describing Service-Oriented Architectures (SOA). Ontologies are utilized as a major representation mechanism for describing various elements available in the architecture. The methodology proposes an architecture specification mechanism to constuct a unified ontology that enables transition from design concerns to the modeling elements. A multi-level modeling is also [...]

Using learned affordances for robotic behavior development

By admin

“Developmental robotics” proposes that, instead of trying to build a robot that shows intelligence
once and for all, what one must do is to build robots that can develop. A robot should go through
cognitive development just like an animal baby does. These robots should be equipped with
behaviors that are simple but enough to bootstrap the system. [...]

System simulation for software quality assurance (SQA)

By admin

Software development and maintenance is an error-prone, time-consuming and
complex activity. To evaluate the quality of a software product and to keep its level
high is much more difficult than to do them for the other industrial products.
In this thesis, to keep the quality level of software products high, firstly necessary
quality factors on organizational level and department/project [...]

Developing a data warehouse for a university decision support system

By admin

Data warehouse is an important contemporary issue for many organizations
and is relatively a new field in the realm of information technology. As data
warehousing is a new field, little research has been done regarding the characteristics
of academic data and the complexity of analyzing such data. Educational institutions
measure success very differently from business-oriented organizations and the

Ontology based semantic retrieval of video contents using metadata

By admin

The aim of this thesis is the development of an infrastructure which is used for semantic retrieval of multimedia contents. Motivated by the needs of semantic search and retrieval of multimedia contents, operating directly on the MPEG-7 based annotations can be thought as a reasonable way for meeting these needs as MPEG-7 is a common [...]

Mobility and power aware data interest based data replication for mobile and hoc networks

By admin

One of the challenging issues for mobile ad hoc network (MANET) applications is
data replication. Unreliable wireless communication, mobility of network
participators and limited resource capacities of mobile devices make conventional
replication techniques useless for MANETs. Frequent network divisions and
unexpected disconnections should be handled. In this thesis work, a novel mobility
and power aware, data interest based data replication [...]
