Visual memory for recent information
… providing a source of hypotheses against which current input is tested. To make this contribution it should neither require active processes for its maintenance nor be overwritten by subsequent visual events. There is little evidence for a visual memory with these characteristics. However, the …

Wide-Dynamic-Range Continuous-Time Delta-Sigma A/D Converter for Low-Power Energy Scavenging Applications
… For most photo-detector-based applications, the input-current is integrated onto a capacitor, either with a variable time, or a variable capacitor value, followed by a sample-and-hold and a voltage A/D converter. The penalty for achieving wide-dynamic-range with the above approach is power and …

Use of conducting sheet analogy for solution of heat transfer problems in a nuclear reactor
… The voltage distribution in a flat plate with current input normal to the plate is ∂²Y/∂x² + ∂²Y/ ∂Y² = -p<sup>i(x,y)</sup> Where, p is the resistivity of the plate. i(x,y) is the function describing the current input. The development of the nuclear reactor for the production of commercial …

Market-based approach for improving ship air emissions
… the maritime community. The study considered the current input and discussions within the International Maritime Organization and its Marine Environment Protection Committee and identified three major thought patterns in proposed systems for the maritime industry: (1) an emissions trading scheme …

Modeling effects of adding a flux channel to a planar magnet-coil actuator
… one way to improve the actuator range per current input of planar coil actuators. This is accomplished by adding a flux channel around and beneath the actuator's magnet. The Lorentz force is created by putting a current carrying planar coil over a magnet in an actuator assembly. The Lorentz …

Stability of static input-output systems with optimized subsystems: quantity and price models
… of the pattern of structural change in a static input-output system is considered, when a series of operational optimizations are performed in one or more subsystems. Specifically, changes in the relative price of each commodity in an economy, along with their implications for the quantities …

Speech recognition with probabilistic transcriptions and end-to-end systems using deep learning
… hard alignment problem as it relies only on the current input to generate the current output. In reality, the output at the current time is influenced not only by the current input but also by inputs in the past and the future. Thus, the second part of the thesis proposes advancing …

Safety verification and control for collision avoidance at road intersections
… monitor the dynamical state of vehicles and the current input of drivers and override them if necessary to prevent a collision. The primary technical problem in the design of such systems is to determine if the current drivers' input will cause an unavoidable future collision, in which case the …

Nonlinear Mr Model Inversion for Semi-Active Control Enhancement With Open-Loop Force Compensation
… to have a linear relationship between the current input and the force output at a given relative velocity. Often this assumption is made implicitly and without knowledge of the underlying nonlinearity. This thesis shows that the overall performance of a semi-active Skyhook control system …

Comparison of Linear, Nonlinear, Hysteretic, and Probabilistic MR Damper Models
… their effective damping force depending on the current input to the damper. A number of factors in the construction of the damper, as well as the properties of the fluid and the electromagnet, create a dynamic response of the damper that cannot be fully described with a static model dependent on …

Comparison of the abilities of historical and current cost information to predict funds flows
This study compared current operating income (COI), current operating income plus realizable holding gains measured in constant dollars and purchasing power gain (i.e., current real income (CRI)), and historical cost income measured in nominal dollars (HCI) on their ability to predict future funds …
