In this paper a relationship between two approaches towards construction of genuinely two-dimensional upwind advection schemes is established. One of these approaches is of tile control volume type applicable on structured cartesian meshes. It resulted (see [14], [15]) in the compact high resolution schemes capable of maintaining second order accuracy in both homogeneous and inhomogeneous cases...

This paper presents a novel countermeasure against Distributed Denial-of-Service (DDoS) attacks that we call the rouTer poRt mArking and paCKet filtering (TRACK), which includes the functions of both IP traceback and packet filtering. TRACK is a comprehensive solution that is composed of two components: a router port marking module and a packet filtering module. The former is a novel packet mar...

Isogeometric analysis (IGA) has been recently introduced as a viable alternative to the standard, polynomial-based finite element analysis. One of the fundamental performance issues of the isogeometric analysis is the quadrature of individual components of the discretized governing differential equation. The capability of the isogeometric analysis to easily adopt basis functions of high degree ...

This research explores the perspectives of public library staff on the subject of bibliotherapy. Bibliotherapy is either using non-fiction advisory texts to help people understand and deal with mental and physical health problems, primarily mild mental health difficulties including mild to moderate depression, or it is using fiction books to provide enjoyment for people with similar health prob...

Current resource provisioning schemes in Internet services leave servers less than 50% utilized almost all the time. At this level of utilization, the servers’ energy efficiency is substantially lower than at peak utilization. A solution to this problem could be dynamically consolidating workloads into fewer servers and turning others off. However, services typically resist doing so, because of...

The forestry industry provides a good illustration of the active roles that industry associations, environmental nongovernmental organizations (NGOs), national governments, and international organizations can play in developing and promoting codes of conduct that are formally sanctioned and certified. It also reflects some of the challenges of disseminating codes of conduct in developing countr...

Visual perceptual disorders are often presented as a disparate group of neurological deficits with little consideration given to the wide range of visual symptoms found in psychiatric and neurodevelopmental disease. Here, the authors attempt a functional anatomical classification of all disorders linked to visual perception, whatever the clinical context in which they arise, including those dis...

T the ripe age of eighty-four Lloyd Morgan has passed away. jje wag for many years the distinguished and greatlyeloved Principal of University College, and when the College deceived its charter in 1909 converting it into Bristol diversity Lloyd Morgan was designated the first Vicehancellor. He relinquished this office almost immediately, nd Sir Igambard Owen was appointed in his stead. His ecis...

The aphorism “All models are wrong but some are useful” (Box, 1978) sums up much of what ML is about. The assumptions we make in the Naive Bayes approach to sentimanet classification are wrong, but this is true of the assumptions made in all current formal models of human language (statistical or otherwise), with the possible exception of a few which are very restricted indeed. However, the que...
