Relative Time Delay and Absolute Time Delay

This paper has explained that, the motion can be divided into two types, i.e. relative motion between two objects and circular motion unrelated to relative motion (also known as absolute motion). Time delay resulted from relative motion is referred to as relative time delay; time delay caused by circular motion is referred to as absolute time delay. Relative time delay refers to a time delay ef...

Evaluating of Relative and Absolute Cumulative Input Energy Time History subjected to Forward Directivity Earthquakes

In this article, to study the effect of pulse-type near-fault earthquakes on the seismic demands of steel moment frames, 15-story 2D-frame was analyzed under the influence of 20 near-fields with forward directivity effect and 2 far-field records. The relationship between Effective Cyclic Energy, ECE and displacement demands, velocity and hysteretic curve of SDOF systems in two near- and far-fau...

Absolute Identification 1 Running Head : RELATIVE JUDGMENT MODEL Absolute Identification by Relative Judgment Neil Stewart

In unidimensional absolute identification tasks, participants identify stimuli that vary along a single dimension. Performance is surprisingly poor compared to discrimination of the same stimuli. Existing models assume that identification is achieved using long-term representations of absolute magnitudes. We propose an alternative relative judgment model (RJM) in which the elemental perceptual ...

Relative versus absolute stimulus control in the temporal bisection task.

When subjects learn to associate two sample durations with two comparison keys, do they learn to associate the keys with the short and long samples (relational hypothesis), or with the specific sample durations (absolute hypothesis)? We exposed 16 pigeons to an ABA design in which phases A and B corresponded to tasks using samples of 1 s and 4 s, or 4 s and 16 s. Across phases, we varied the ma...

qPCR-DAMS: a database tool to analyze, manage, and store both relative and absolute quantitative real-time PCR data.

Quantitative real-time PCR is an important high-throughput method in the biomedical sciences. However, existing software has limitations in handling both relative and absolute quantification. We designed quantitative PCR data analysis and management system (qPCR-DAMS), a database tool based on Access 2003, to deal with such shortcomings by the addition of integrated mathematical procedures. qPC...
