This paper studies the problem of testing if an input (Γ, ◦), where Γ is a finite set of unknown size and ◦ is a binary operation over Γ given as an oracle, is close to a specified class of groups. Friedl et al. [Efficient testing of groups, STOC’05] have constructed an efficient tester using poly(log |Γ|) queries for the class of abelian groups. We focus in this paper on subclasses of abelian ...

Cyclic stress strain curves (CSSC) response of Al-2024 Annealed condition was conducted under symmetric tension-compression at room temperature and constant frequency, using a servo-hydraulic testing machine, to study the effect of cooling rate on cyclic stress strain curves (CSSC) response. The fatigue response of Al-2024 alloy was evaluated macroscopically in terms of cyclic stress strain res...

This paper concerns the systematic testing of robotic control software based on state-based models. We focus cyclic systems that typically receive inputs (values from sensors), perform computations, produce outputs (sent to actuators) and possibly change state. provide a theory for such where time can be represented probabilities are used quantify non-deterministic choices, making it possible m...

Present paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were test...

BACKGROUND Artificial calcanei, fresh-frozen cadaver specimens, and embalmed cadaver specimens were compared in experimental testing under biocompatible loading to clarify the biocompatibility of artificial calcaneal specimens for implant testing. METHODS Two different artificial calcaneal bone models (Sawbone, Pacific Research Laboratories, Vashon, WA, and Synbone, Synbone Inc., Davos, Switz...

The Direct Simple Shear (DSS) test is one of the laboratory element testing devices that has been widely used to assess soil behavior. Although the DSS test is considered to simulate the cyclic shear loading mode from the earthquakes in an effective manner, the most commonly used versions of the test device (such as the NGI-type DSS device) do not provide means of measuring the lateral stresses...

An exhaustive search for (1023, 511, 255)-cyclic difference sets has been conducted. A total of 10 non-equivalent (1023, 511, 255)-cyclic difference sets have been found, all of which are members of previously known or conjectured infinite families. A fast and effective autocorrelation test method was utilized that can also facilitate the testing of longer sequences.
