Memory is commonly viewed as an unreliable place to store permanent data (files) because it is perceived to be vulnerable to system crashes. Yet despite all the negative implications of memory’s unreliability, no data exists that quantifies how vulnerable memory actually is to system crashes. This paper quantitatively compares the vulnerability of disk and memory to operating system crashes. We...

Digital interpretation of imagery produces descriptions of the earth’s surface, each description relying on the inherent resolution of the original image. Forest cover geographic information (GIS) files have been produced by interpretation of aerial photography. Common mapping scales in Canada for representing land information are 1:20,000 and 1:250,000. This paper discusses two methods to auto...

This paper reports on a work-oriented design project concerned with the question of how to migrate shared, workgroup document collections currently kept on paper online. Based in a civil engineering work group, the focus of our project is a document collection called the "project files," a heterogeneous mix of documents that serve as an ongoing resource for the group during a project's course a...

The most frequently used language to represent the semantic graphs is the RDF (W3C standard for meta-modeling). The construction of semantic graphs is a source of numerous errors of interpretation. The processing of large semantic graphs is a limit to the use of semantics in current information systems. The work presented in this paper is part of a new research at the border between two areas: ...

Your solution to the written assignment should be submitted as a PDF file named hw 4 written.pdf in the hw 4 directory. This is important — you will be penalized 10 points if you place the file in some other folder or with some other name. The PDF file can be created however you choose. If you scan handwritten text, make sure that you use a proper scanner (not a digital camera) to create the PD...

The Windows Registry often contains key data that help determine the activities performed on a computer. While some forensic tools format Registry data for common questions that are required to be answered in digital investigations, their output is geared for standalone use, not for indexable content. This paper describes RegXML, an XML syntax designed to represent Windows Registry hive files. ...

In contemporary computing systems accesses to information objects are traced and logged for various reasons. In this paper we shall show how information about the role structures of information communities/societies may be deduced from available trace files which record the interactions of users with information systems. The key idea is that in the future social roles of individuals will be det...

XML is one of the greatest innovations of the digital world. It has taken the field of Web Technology by storm in the past decade and is becoming an ever-present technology in other fields too. XML with its easy usage has lot of future. But the parsing performance of XML is a big hindrance to its development. Particularly, when dealing with huge XML files, normal XML parsers like DOM, SAX parse...
