Modal testing using high speed digital speckle pattern interferometry
… by the use of multiple measurement points. A temporal phase-stepped CMOS high-speed SPI system was used to capture the transient vibration response of two overlapping plates, the system had a maximum surface velocity of 1.4 mm/s and the results were compared to accelerometer data and …

Developing and testing of a prototype electro-optical phase encoded position transducer
… a proposed idea for a prototype electro-optical phase encoded position transducer was conducted. The intensity of two IR LED beams were modulated sinusoidally at frequency omega, with a 90 degree temporal phase difference. They further modulated by a pair of sinusoidal optical encoding masks with …

Complex Field Analysis of Temporal and Spatial Techniques in Digital Holographic Interferometry
… to process the digital holographic interference phase maps in complex field is proposed. Based on this concept, three temporal phase retrieval algorithms and one spatial retrieval approach are developed. Temporal complex phasor method is highly immune to noise and allows accurate measurement of …

Exploring the occupational history of the Middle Ontario Iroquoian Dorchester Village site
… to correspondence analysis to seek plausible temporal sequences. The Brainerd Robinson coefficient of similarity was used to identify plausible temporal phase groups of longhouses by comparison of vessels attributed to specific houses. Multiple ceramic attributes were explored, and the …

A novel visual stimulation paradigm: exploiting individual primary visual cortex geometry to boost steady state visual evoked potentials (SSVEP)
… oscillatory summation, by manipulating flicker-phase offsets among angular segments of a large annular stimulus. We found that by dividing the annulus into standard octants, flickering upper horizontal octants with opposite temporal phase to the lower horizontal ones, and left vertical octants …

An Exploratory Biomechanical Analysis of the Side-to-Side Swing Patterns of Three Skilled Switch Hitters
… swing was broken down into specific events and temporal phase parameters were obtained. Peak vertical ground reaction force of each foot and stride length of each swing were also obtained. All variables were statistically analyzed using paired t-tests. The subjects displayed surface swing …

Neurons in Cat Primary Visual Cortex cluster by degree of tuning but not by absolute spatial phase or temporal response phase
… also clustered in their tuning for the spatial phase of a flashed grating ("absolute spatial phase") or the temporal phase of a drifting grating ("temporal response phase")? To address these questions, we used tetrode recordings to simultaneously isolate multiple cells at single recording sites …

Environmental Cues in the Seasonal Development of the Southern California Annual Grassland
… experience a succession of seasonal phases which provide for the coexistence of various species by allowing them to make their major demands upon environmental resources at different times. Thus, an ecosystem furnishing certain resources at a limited rate is enabled to support a …

Using Locality and Interleaving Information to Improve Shared Cache Performance
… workloads shows that cache set mapping and temporal phase result in the variation of interleaving granularity. When memory references from dierent threads map to disjoint cache sets, or they occur in distinct time windows, they tend to cause little interference due to coarse-grain …

Contemporary and novel assessment of biomechanics in plyometric and ballistic exercise and the implications for elite and recreational athletes
… a more discrete assessment of PF within specific phases of the jump, described as impact, braking, concentric and landing phases, to extend previously described methods within the literature and increase the level of insight into the specific demands on an exercise. The highest forces were …

Femtosekunden-Spektroskopie biologischer Systeme mittels kohärenter Kontrolle
… a photoreaction with femtosecond pulses whose temporal phase and amplitude are shaped in such a manner that specific molecular vibrations and states are addressed, the energy flow can be steered at will. The comparison between the ensuing energy flow patterns following shaped and unshaped …

On-chip spectrometers with photonic integrated circuits
… shifted across the spectral domain by applying temporal phase modulations. This waveform shifting enables the circular convolution operation on an arbitrary input spectrum, thereby achieving its flawless recovery. The recovery process involves only (inverse) Fourier transforms, thus resulting in …
