Abstract:
With the expansion of the grid, continuous reactive power compensation is vital for efficient operation of long transmission power lines or cables. Yunnan Electric Power Grid is planning to development saturable reactors for 500 kV long distance AC transmission lines. As the first stage of the development plan, the appropriate saturable reactor structure should be presented and verified by experiment. In this paper, different ferromagnetic materials, core structures and winding arrangements of saturable reactors are analyzed. Then, appropriate saturable reactor structure is determined by simul

Abstract:
The structure of the sensor endurance test station is designed. Satisfied with the request of the performance, structural parameters of the spindle and bearing are calculated to minimize the spindle mass using optimization theory. By the static analysis, fatigue analysis and frequency analysis of spindle and bearing using the FEM, the simulation results indicate that the optimized structures can meet the demands for the strength and dynamics of the flywheel system, which leads to safe and stable work, improve design efficiency effectively, shorten design cycles, and reduce production costs.

In order to improve the output performance of multi-chamber piezoelectric pumps, this paper proposes a novel design for a four-chamber series–parallel piezoelectric pump, based on the characteristics that the parallel chamber structure significantly increases the output flow rate, and the series chamber structure effectively improves the output pressure. The theoretical output flow rate and pressure of the four-chamber series–parallel piezoelectric pump were calculated, and a prototype was fabricated.

Abstract:
A full-scan structure is described, in which the classic single serial scan-path and the parallel-in/serial-out scan (PASE-Scan) designs coexist. It requires only one extra pin and a small hardware overhead with respect to the single serial scan-path approach, and is compatible with a test scheme of this type. A method for the structure design is outlined and a structure-oriented optimized procedure for obtaining the test is proposed which considerably reduces the test application cost with respect to the serial scan case, improving the previous results for parallel-serial designs.

This study is concerned with the effect of placing text into a mediated structure form upon the generation of test items for analysis level domain referenced test construction. The item writing methodology used is the linguistic (operationally defined) item writing technology developed by Bormuth, Finn, Roid, Haladyna and others. This item writing methodology is compared to 1) the intuitive method based on Bloom's definition of analysis level test questions and 2) the intuitive with keywords identified method of item writing.

These additional loads can significantly reduce the collapse pressure of the pipe.

Abstract:
NIST work developed processes to identify the stress/strain/crack velocity conditions for unstable high-rate ductile crack propagation found in a full-scale pipeline burst test and duplicate those conditions in a medium-scale test. With modeling to validate conditions and assumptions used in reducing the scale of the tests. A medium-scale test to elucidate material property data necessary to qualify high-strength high-toughness steels based on the correlation to large-scale tests. Parametric determination of the material properties governing fracture propagation or arrest-ability was developed

The US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (CHL), used the Ship/Tow Simulator to evaluate navigational conditions for the US Army Corps of Engineers, St. Louis District (MVS), proposed 1,200 feet (ft) lock chamber at Lock and Dam 25 in a tow simulation study. The study considers the impacts to navigation throughout construction sequences of the proposed 1,200 ft lock chamber and the final completed project. Testing occurred at CHL in October–November 2022 with five industry tow pilots. A total of 47 unique test conditions for a total of 187 ship-sim

Abstract:
Bridges often serve as key links in local and national transportation networks. Bridge closures can result in severe costs, not only in the form of repair or replacement, but also in the form of economic losses related to medium- and long-term interruption of businesses and disruption to surrounding communities. In addition, continuous functionality of bridges is very important after any seismic event for emergency response and recovery purposes. Considering the importance of these structures, the associated structural design philosophy is shifting from collapse prevention to maintaining funct

This executive summary provides a brief overview of a project which evaluated the processes and impact of the Postgraduate Certificate (PGCert) and Master’s (MA) in Student Engagement in Higher Education at the University of Winchester. The postgraduate programme of study focuses on student engagement practices, policies and partnerships in UK Higher Education (HE) and it was created in 2018 to address a lack of professional development opportunities for practitioners who are responsible for engaging with students in HE. A Theory of Change approach was adopted to structure the evaluation, whic

Abstract:
Most pipelines in Class 1 areas are currently designed to a utilization factor of 0.72 using steel grades of up to X70. Using higher strength steels and/or a higher design factor can reduce the wall thickness and construction cost of such pipelines. High strength steels tend to have high yield-to-tensile ratios and lower overall post-yield tangent stiffness. This raises concerns about the potential for excessive plastic deformations under high hydrostatic test pressures. Combined with a high design factor, high steel grades will also lead to thinner pipe walls and reduced tolerance to thicknes
