Commentary—The “Tar Baby” of Computing: Performance Analysis [PDF]

open access: bronzeORSA Journal on Computing, 1993
It looks so easy. To find the speed of a computer, just take a job and time it. To compare two speeds, or try to establish speed in some type of universal unit, well…. Reporting performance is the “tar baby” of computing, and many authors and researchers have attacked this issue only to find themselves stuck in a mess of shaky logic and shakier ...

The Impact of Social Media on Student’s Academic Performance: A Survey on TAR UC Computing Students in Malaysia during Covid-19 Pandemic [PDF]

open access: goldConference Proceedings: International Conference on Digital Transformation and Applications (ICDXA 2021), 2021
Social media has become an inevitable tool in daily life for communication, entertainment, learning, and business. However, social media can cause addictive especially among university students. The aim of this study is to investigate if there is a relationship between social media usage and students’ academic performance focusing in factors: social ...

Validation of computational liquefaction for tailings: Tar Island slump [PDF]

open access: yesGeotechnical Research, 2022
Finite-element analyses using critical state theory proved necessary to understand the development of static liquefaction during three recent large tailing dam failures at Fundao (in Brazil), Cadia (in Australia) and Brumadinho (in Brazil). However, the complexity of these events prevents these analyses being viewed as a complete validation of the ...

Evolutionary Computational Approach in TAR Model Estimation [PDF]

open access: yesSSRN Electronic Journal, 2011
The well-known SETAR model introduced by Tong belongs to the wide class of TAR models that may be specified in several different ways. Here we propose to consider the delay parameter as endogenous, that is we make it to depend on both the past value and the specific past regime of the series.

Structure of TAR RNA Complexed with a Tat-TAR Interaction Nanomolar Inhibitor that Was Identified by Computational Screening [PDF]

open access: yesChemistry & Biology, 2002
HIV-1 TAR RNA functions critically in viral replication by binding the transactivating regulatory protein Tat. We recently identified several compounds that experimentally inhibit the Tat-TAR interaction completely at a 100 nM concentration. We used computational screening of the 181,000-compound Available Chemicals Directory against the three ...

Unsupervised Conditional Reflex Learning Based on Convolutional Spiking Neural Network and Reward Modulation

open access: yesIEEE Access, 2020
Automatic decision and lane-keeping tasks are the most fundamental but important tasks in robot controlling researches. Concerned about the computing limitations of mobile robot platforms, an easily trainable method with low computational consumption and

Structure-Based Computational Database Screening, In Vitro Assay, and NMR Assessment of Compounds that Target TAR RNA [PDF]

open access: yesChemistry & Biology, 2002
There has been little prior effort to discover new drugs on the basis of a unique RNA structure. Binding of the viral transactivator Tat to the 5' bulge of the transactivation response (TAR) element is necessary for HIV-1 replication, so TAR RNA is a superb target. A computational approach was developed to screen a large chemical library for binding to

Self-sustaining smouldering combustion of coal tar for the remediation of contaminated sand: Two-dimensional experiments and computational simulations [PDF]

open access: yesFuel, 2015
Abstract This study presents the development and validation of a computational model which simulates the propagation of a smouldering front through a porous medium against unique experiments in coal tar and sand. The model couples a multiphase flow solver in porous media with a perimeter expansion module based on Huygens principle to predict the ...
