Bayesian Analysis of Discrete Longitudinal Data
… the discrete nature of the data, as well as its time dependency. Bayesian analysis is used to make inference on each individual profile, as well as on a group profile for each treatment group.

Effect of vibration exposure duration on discomfort
… of excitation on the Subjective Discomfort Time-Dependency (SDTD) during vibration so as to improve understanding of the mechanisms involved (e.g. the biodynamic responses of the body and muscle activity) and elaborate a model predicting how discomfort evolves with exposure duration. To …

The influence of time-dependent material behavior on the response of sandwich beams
To study the influence of the time-dependent behavior of various materials being considered for use in orbiting precision segmented reflectors, simple sandwich beam models are developed. The beam models included layers representing face sheets, core and adhesive. The issue of time-dependency is …

On the solution of external laminar free convection to power law fluids
… power law fluids have no yield stress and are time independent; in other words, the time dependency of the properties is very small and thus may be neglected in most applications. Typical flow curves for power law fluids are plotted in Fig. 1.1."--Introduction.

Last Call for Life: Habitability of Terrestrial Planets Orbiting Red Giants and White Dwarfs
… red giants and white dwarfs, and assess the time dependency of detectable biosignatures.

The effect of viscoelastic deformation in pipe cracks on leakage response to variations in pressure
… include creep, relaxation, hysteresis and time dependency. When these pipes experience stresses due to water pressures, failure and fracture may occur as leaks. The viscoelastic properties of these materials therefore affect how the leaks respond to pressure change. The effect of …

A coupled thermal-magnetic finite element model for high frequency transformers
… of the soft-ferrite core material permits a time-harmonic transformation of the electromagnetic equations. This eliminates the need to step through time while maintaining the effects of hysteresis losses. Also, a quasi-steady formulation of the heat-conduction equation eliminates the time …

The influence of concrete mix composition and environmental exposure on long-term chloride ingress in concrete
… structures situated in marine exposure classes. Time-dependent chloride ingress was measured over a period of roughly 4 years with respect to the influences of binder type, w/b ratio and environmental conditions, exposing samples to submerged, tidal, splash/spray and airborne chloride exposure in …

A study of lithographic ink and water interactions
… droplet fragmentation, droplet coalescence and time-dependency. Slippage occurred in the hydrophobic systems to a greater extent compared with the hydrophilic systems increasing with water concentrations from 0 to 25% water. Droplet size distributions of the emulsion depend on temperature and …

Engineering aspects of calcium carbonate and magnesium hydroxide precipitation in waste water reclamation
… and magnesium hydroxide precipitation are time dependent. As a consequence of this time dependency unstable effluent may be produced under reaction conditions commonly encountered in practice. An exhaustive study identified the major factors affecting the precipitation kinetics. Reaction …

Interposing the Syscall Boundary: Transparent Python Execution in SigmaOS
… isolation, security, and efficient startup times and scheduling among multiple users. While σOS and its container startup times have been successfully benchmarked for tasks written, compiled, and statically linked in Golang and Rust, it currently lacks support for other languages, including …

Electrical Monitoring of Electromechanical Systems
… research assumes that data is static over time. Also, ground truth labels are a scarce resource in industrial scenarios. Thus, a pattern classifier must train on a limited dataset not representative of long-term operation. This thesis employs an understanding of the physics and …

Hydrogen silsesquioxane (HSQ) for use in nano imprint lithography
… but is a serial process which has undesirable time constraints. EUV is the latest generation of photo-lithography which can produce 35nm features, but has a limited area of exposure. NIL is a high resolution high throughput process, but still has time constraints with imprinter fabrication and …

Functional Data Models for Raman Spectral Data and Degradation Analysis
… data are often collected continually overtime on a subject. In this work, we introduce a new linear contrast test that accounts for time dependency among functional group members. For a significant contrast test, it can be beneficial to identify the region of significant difference. In the …

Development of thermal displays for haptic interfaces
… location of a thermal stimulus. This space-time dependency for the thermal sensory system provides an extra dimension to use to present information in a thermal display and potentially could result in a display that functionally has a higher spatial resolution than the number of thermal …

Numerically Modeling Steel Continuous Bridges for Early Age Concrete Deck Cracking
… deck pours because of ease and construction time. During the period of this TRC1903 research project, ARDOT has only approved a few continuous pours for relatively short bridges, 180 to 190 ft. long. Concrete cracking occurs when concrete tensile stresses exceed the concrete’s tensile …

An investigation into brokered inter-organisational relationships within the supply chain.
… themes of governance, identity, learning and time-dependency that provide `themed lenses' for a reflective review of the research findings and the development of a conceptual framework that enables a comprehensive understanding of the broking process. Each of the themes is explored in the …

Simulation studies of Brownian motors
… the motion of diffusive particles using a time dependent, asymmetric potential energy landscape, and the transport speed of the ratchet can be increased if information about the particle distribution is incorporated as feedback in the time dependency of the landscape. Using a Langevin …

Spectral hulls: a degree of freedom reducing hp-strategy in space/time
… of such procedure is first investigated in time only by letting the spatial discretization to be fixed to an arbitrary spectral/finite element discretization. In this scenario, lower order time steps (elements) are agglomerated into a space-time hull. A general system of Volterra integral …
