The performance shaping factors (PSFs) of the standardized plant analysis risk-human reliability (SPAR-H) method are unclearly defined, which contributes to uncertainty human (HRA) in nuclear power plants (NPPs). This work proposes an expert-based modification approach for redefining PSFs based on four criteria terms less overlap, hierarchy, flexibility, and digitalization. For demonstration, p...

We present the development and application of small buoy systems for wave energy harvesting (free-floating or slackly moored), to produce about 1 KW per unit at full scale. These systems are targeted for powering distributed marine surveillance and instrumentation networks, and should be simple in concept, easily deployable, storm resilient, and low maintenance. Our work involved design, experi...

The aim of the present study was to examine the effect of homonymous visual field defects (HVFDs) on collision avoidance of dynamic obstacles at an intersection under virtual reality (VR) conditions. Overall performance was quantitatively assessed as the number of collisions at a virtual intersection at two difficulty levels. HVFDs were assessed by binocular semi-automated kinetic perimetry wit...

We present a series of results acquired at a 2-kilometer distance using our lidar system under several weather conditions, clear, cloudy, light rain, moderately foggy, and night. The experimental results show that ghost imaging lidar via spar-sity constraints can realize imaging in all these weather conditions.

Two recent studies by Sheng and associates (Pak et al., 2001; Sala et al., 2001) provide an elegant molecular analysis of the role of a spine-specific protein, SPAR, and the synaptic proteins Shank and Homer, in regulating dendritic spine morphology, and the possible functional consequences of this regulation.

In this paper, the sensitivity of the structural integrity of wind turbine blades to debonding of the shear web from the spar cap was investigated. In this regard, modal analysis, static and fatigue testing were performed on a 45.7 m blade for three states of the blade: (i) as received blade (ii) when a crack of 200 mm was introduced between the web and the spar cap and (iii) when the crack was...

This paper presents an approach to the automatic generation of schematic diagrams from circuit descriptions. The heuristics which make up the system are based on two principles of schematics readability: Functional Identi cation and Traceability. SPAR's generation process is broken into ve distinct phases: partitioning the netlist, placement of components on the page, global routing, local rout...

A main conclusion of this work by Robars et al. is that a piece of Iceland spar (optical calcite) can be used in a simple manner to find the direction to the Sun using polarized light, even when the Sun is obscured by clouds or just below the horizon, which supports the possible role of the renowned sunstones discussed in Viking Sagas. They propose a method of using an opaque spot on the incomi...

In Europe and Japan, various types of floating wind farms are being constructed. recent years, the size turbines has been increasing, structures have also getting larger. The generally classified into a semi-submersible, spar, barge types. advantages disadvantages each type depending on construction cost, response characteristics in waves, water depth (depending draft structure). semi-submersib...
