Planning of forest transportation is a complex problem that requires effective and harmonious design implementation various operations including extraction, loading, hauling products. These constitute significant part the total cost producing products; therefore, developing most appropriate (minimum cost/maximum net profit) plan has increasing importance for economic aspect. Computer-aided mode...

This paper details work undertaken on the application of an algorithm for visual attention (VA) to region of interest (ROI) coding in JPEG 2000 (JP2K). In this way, an ‘‘interest ordered’’ progressive bit-stream is produced where the regions highlighted by the VA algorithm are presented first in bit-stream. The paper briefly outlines the terminology used in JP2K, the packet structure of the bit...

This document is intended for people who want to “be aware” of some of the mechanisms underlying the JPEG2000 image compression standard [2]. While writing this tutorial my objective was to give to the reader the feeling of what goes on when compressing images with JPEG2000 . Hence, this tutorial should be regarded as introductory material which requires further reading to reach a deeper unders...

In this paper, we investigate the error resilience properties of JPEG2000. Through a careful analysis of the structure of JPEG2000 codestreams, we identify the dependencies among coding passes of a codeblock. In our analysis, we consider the effects of mode variations provided by the standard for low-memory, low-complexity implementations. The proposed methods are derived using the existing dep...

The rapid evolution of wireless networks is driven by the growth of wireless packet data applications such as interactive mobile multimedia applications, wireless streaming services, and video-on-demand. The largely heterogeneous network structures, severe channel impairments, and complex traffic patterns make the wireless networks much more unpredictable compared to their wired counterparts. O...

This manual is only partially complete and is a work in progress. A completed manual will be available by January 1,2000. Cluster and TreeView are Y2K Compliant because they are oblivious of date and time.

The advent of reconfigurable nodal elements, such as Optical Add/Drop Multiplexers (OADM) and CrossConnects (OXC) for Wavelength Division Multiplexed (WDM) networks, has led to a myriad of possible network architectures for the optical layer. In this paper we describe different architectures for resilient ring and mesh based WDM networks, and compare these architectures from a conceptual viewpo...
