The idea for this note arose during the “Web Information Retrieval and Linear Algebra Algorithms” held at Schloss Dagstuhl in February 2007. Many brilliant people working on either side (numerical analysis and web search) had a chance to meet and talk for one week about mathematical and practical aspects of linear methods for ranking, and in particular (not surprisingly) PageRank and HITS. Ther...

The spread of the cover sheet is a divisive phenomenon. Their appearance is geographically bound and their content situated in the local political and financial context. In this article we discuss the arguments for and against the coversheet in its guise as a fixture on institutional repository preprints, exploring the issue through statistical information gathered from survey material and from...

As the INT community matures, one hears increasing calls for the field to become more scientific, and even prior restraint in which researchers avoid a project entirely out fear it wouldn’t be sufficiently scientific. In this position paper, I’ll argue that science, and more generally rigor, are not well served by a discourse that labels things as “science” and “not science.” In particular, I w...

This study examines the random waypoint model widely used in the simulation studies of mobile ad hoc networks. Our findings show that this model fails to provide a steady state in that the average nodal speed consistently decreases over time, and therefore should not be directly used for simulation. We show how unreliable results can be obtained by using this model. In particular, certain ad ho...

This paper studies the causal e¤ect of aid volatility on the economic performance of developing countries in 2000-2009 period. We construct a time-varying measure of aid volatility using autoregressive conditional heteroskedasticity (ARCH). We control for the endogeneity of aid ‡ows by using as instruments for aid volatility three characteristics of donor counitres: (i) their budget de…cits ; (...

The memory bus must work. Given the current status of Bayesian archetypes, physicists particularly desire the exploration of Moore's Law. We describe a metamorphic tool for visualizing thin clients, which we call BETRIM. Keywords— sensor networks,memory bus,betrims,,DHCP

Many current approaches to statistical language modeling rely on independence a.~sumptions 1)etween the different explanatory variables. This results in models which are computationally simple, but which only model the main effects of the explanatory variables oil the response variable. This paper presents an argmnent in favor of a statistical approach that also models the interactions between ...

Let me answer this question unequivocally. It depends. Figured out I’m a consultant yet? Actually, let me explain. It does depend. It depends on what you think patterns are. Many people have a misunderstanding of patterns, and for those people, patterns can be harmful. However, when people get past their early understanding of patterns and come to comprehend them in a richer way, patterns canno...

The Test Vector Concept A test system based on vectors has several defining characteristics: • There is a “vector sequencer” that defines which “vector” will be obeyed next. • The vector sequencer broadcasts a small amount of information (such as vector address, period numbers and timeset numbers) to all of the pin channels. • The pin channels access a small pin command, usually of between 1 an...
