Color characteristics of computer monitors and similar display devices can significantly alter the way an image is perceived by the human eye. Modern cameras and software applications are able to create vibrant scenes and retain their original colorfulness through an embedded ICC[1] profile. Gamut differences between input and output mediums require color management techniques in order to preserve...
In order to estimate the security of the Web apps, there has been proposed the design and built of a model for evaluating security on Virtual Learning Environments (VLE), starting from the identification of security criteria proposed in handbooks, rules and standards, and there were established objectives and activities that gave patterns for carrying out such process, making emphasis on three criteria:...
The Locator/Identifier Separation Protocol (LISP) was specified a few years ago by the Internet Engineering Task Force (IETF) to enhance the Internet architecture with novel inbound control capabilities. Such capabilities are particularly needed for multihomed networks that dispose of multiple public IP routing locators for their IP networks, and that are willing to exploit them in a better way than...
Withstanding multiple false identities, also known as a Sybil attack, is one of the main challenges in securing structured peer-to-peer networks. Poisoning routing tables through these identities may make the routing process, needed for storing and retrieving resources within a DHT (Distributed Hash Table), extremely difficult and time consuming. We investigate current possible countermeasures and...
Mapping an IP address to the Autonomous System announcing it is a key feature in network monitoring, and - as a consequence - in network management and research. An informed choice of the tool to use and of the database to query, is of extreme importance for the consistence of the obtained results. In this paper, we evaluate the reliability of the whois tool and the consistence of its results while...
This paper proposes the standard specification of metric numbers and is intended to discuss the topic. The numbers combined with metric prefixes like the 2k for the year, or 2k2 for resistors inscription are popularly used. However, there exists no standard to guide the use of such numbers, and typical precision is limited to few digits, as in the E24 series used for electronic parts. Computational...
In this paper, consideration is given to extending an existing on-line tutorial system in order to understand the user experience with the tutorial by including analysis of the tool use. The areas of web analytics and learning analytics will be considered and used. Reference to how web analytics tools are used and the features they provide will be made. Features of available analytics tools will be...
Recently, the number of remote systems using the Internet has been increased and the services provided by such systems get various. They are required to have high dependability. The existing evaluations have some problems. For example, the evaluations based on RASIS are vague and those provided by Japanese government are very complicated. The existing evaluations are not uniformed, not understandable,...
