Design, fabrication, and testing of a mechanical timer in application of a stored-heat solar cooker
… by designing, building, and testing a mechanical timer. Several design choices were narrowed to the fabrication and testing of a hydraulic design similar to a gas spring. After this particular iteration of the prototype, proof of concept seems feasible. The next iterations of this timer should …

Investigating the roles of candidate gap genes from the neuroblast timer series during axial patterning in the beetle Tribolium
… I investigate the hypothesis that the neuroblast timer genes nubbin (nub) and castor (cas) may act as components of the gap gene network in Tribolium. I first utilise Hybridisation Chain Reaction in situ hybridisation to produce a comprehensive description of the dynamics of gap gene expression in …

Development and implementation of hardware and software for a minicomputer based programmable interval timer for use in point process analysis of neuronal action potentials
A precision programmable interval timer (PIT) for use in point process analysis of the neutronal action potentials derived from multiple extracellular electrode arrays is described. The PIT is based on a commercially available LSI package, INS8253 and is interfaced to a Data General (DG) microNova …

Being in the right place at the right time : time of day discrimination by pigeons, Columba Livia
… phase shift. This finding rules out an interval timer and suggests that a circadian type of timing mechanism, with a self-sustaining oscillator, mediates time-place learning over a period of 24 hr. Further support for this notion was found in Experiment 5 in which subjects were tested in constant …

Reliability management framework for softwarized networks
… facilitates multiple discovery frequency timers for each target over different stratum instead of using a uniform discovery timer for the entire network. It supports many common reliability monitoring factors for registered applications by analyzing offline and online network architecture …

A Lyapunov-based small-gain theorem for interconnected switched systems
… switching signal being modeled by an auxiliary timer, a correspondent hybrid system is defined to enable the construction of hybrid ISS Lyapunov functions. Apart from justifying the ISS property of their corresponding switched systems, these hybrid ISS Lyapunov functions are then combined to …
