Recent Patents on Computer Science - Volume 4, Issue 2, 2011

Mobile devices are radically changing the way in which we work and communicate. The most innovative smartphones provide several features that support, without additional hardware, the adoption of Augmented Reality interfaces in mobile applications, enabling the combination of the real world with virtual information on the device screen. In the original vision, Augmented Reality enabled only to superimpose relevant infor Read More

Business Process Management Systems are increasingly used by organizations to define, coordinate, analyze and improve their business environment. Business Process Management Systems and Decision Support have a large commercial potential and it is a very interesting field for research and invention. In this paper, an overview of recent patents related to Business Process Management over the past seven years is given.

The area of software development has undergone a rapid expansion and this trend is so far continuing. Each developer has to learn constantly and master new technology. However, the foundation a developer gains at the beginning of his/her career playing a crucial role. An essential part of studies at faculties preparing students in the area of computer science is the development of student's ability to think algorithmically. Th Read More

Image retrieval aims at searching similar semantic contents of images to the users' queries. However, the major challenge of image retrieval is to make computers understand high-level concepts of images, e.g. objects. In other words, automatic image annotation by object recognition and categorization can achieve semantic-based image retrieval. However, object categorization is a very important and challenging problem Read More

Serving as an important data storage medium for information and data processing systems, hard disk drives (HDD) are once again called to increase recording density toward regions of multi-terabyte (TB) per inch square to meet the ever-increasing demand for information storage. With such demand, requirement for high accuracy in positioning magnetic read/write elements on spinning magnetic disks for data accessing Read More

Research community has been showing an immense interest for more than a decade in issues related to providing better than best effort service guarantees on the Internet. A number of options have been explored in this regard. Differentiated Services architecture is one of the proposed solutions that treat traffic flows based on their pre-assigned classes to eliminate scalability issue, otherwise a difficult and non trivial pro Read More

Rapid development of network technologies has led to a proliferation of networked video applications, making efficient and effective assessment of the related Quality of (user) Experience (QoE) an acute need. In literature, there has been a non-uniform view of Quality of Service (QoS) and therefore the concept of QoE is introduced to avoid the confusion. The difference between QoS and QoE is first clarified in this paper. Th Read More
