The study of Temporal Representation and Reasoning is a core area of research in Linguistics, Philosophy and Artificial Intelligence. However, very little work has been done in analysing the principles common to these three areas. This paper attempts to investigate major issues and approaches studied in these disciplines. In this attempt, we discovered the Philosophical origin of Allen’s Interv...

Multiway tables with specified marginals arise in a variety of applications in statistics and operations research. We provide a comprehensive complexity classification of three fundamental computational problems on tables: existence, counting, and entry-security. One outcome of our work is that each of the following problems is intractable already for “slim” 3tables, with constant number 3 of r...

We argue that argument encoding systems that seem to involve three syntactic core cases (nominative/absolutive, ergative, accusative) are actually common ergative or accusative systems syntactically, with overt case markers for each of the two cases that disappear in intransitive contexts. Based on evidence from Kham, Djapu, Nez Perce, Upriver Halkomelem, Dyirbal, and Pitjantjatjara, we show th...

Removal of noise is an important step in the image restoration process, and remains a challenging problem in spite of the sophistication of recent research. Popular approaches can be categorized in various ways, a classical one of which involves minimization of variation in an image. This report presents a comparison of three such classical image denoising methods, all minimizing the variation ...

In this article we show that there exist measurable sets W ⊂ R2 with finite measure that tile R2 in a measurable way under the action of a expansive matrix A, an affine Weyl group f W, and a full rank lattice e Γ ⊂ R2. This note is follow-up research to the earlier article ”Coxeter groups and wavelet sets” by the first and second authors, and is also relevant to the earlier article ”Coxeter gro...

We develop hash-based algorithms for computing a three-way join. The method involves hashing all three relations into buckets, and then joining buckets in main memory, three buckets at a time. Comparing to two-cascaded hash joins, the algorithms avoid materializing an intermediate result. We present a cost model for this approach, from which we identify the range of parameters for queries that ...

The role of Pharmacist in making the therapeutic decisions for safe and effective therapy is increasing all over the world. However, there are many aspects of drugs in making these decisions that are less commonly studied such as the correlation of cardiac output with pharmacokinetics of drugs. The cardiac output, besides the other factors, is also affected by drugs like atenolol. Therefore, th...

Teamwork is the typical characteristic of software development, because the tasks can be splitted and parallelized. The independently working developers use Software Configuration Management (SCM) systems to apply version control to their files and to keep them consistent. Several SCM systems allow working on the same files concurrently, and attempt to auto-merge the files in order to facilitat...

Laws that mandate replacement alternatives, reduction alternatives, and refinement alternatives (the Three Rs) in scientific research have been passed in the United Kingdom, Germany, the Netherlands, the United States, and the European Union over the past decade. Full implementation of this newly developed legislation depends upon scientists' ability to understand animal welfare issues and to a...

Likelihood ratio (LR) tests for association and for interaction are examined for three-way contingency tables, in particular, the widely used 2 2 K tables. Mutual information identities are used to characterize the information decomposition and the logical relations between the omnibus LR test for conditional independence across K strata and its two independent components, the LR tests for homo...
