Development Direction

The shaking tables array is the prospective development direction in engineering structural anti-seismic researching field, and which can provide a powerful seismic testing platform. In this paper, the performance of three bi-axial shaking tables array at Fuzhou University was introduced. The trails of bare tables, fully inertial payload shaking tables as well as partly payload shaking tables with elastic structures were conducted. The testing reveals that the shaking tables array system of Fuzhou University has a perfect performance of compliance, coherence and synchronization, which are accepted the required.

The Impact

The study tests representational and computational accounts of morphological variability in English-speaking learners of Spanish by examining performance on gender and number agreement under different task demands. Second language (L2) learners took either a Speeded grammaticality judgment task (GJT) or an Untimed GJT. The tasks targeted agreement violations of two types: errors in the use of ‘default’ morphology and errors involving ‘feature clashes’ (McCarthy, 2008). In addition, three groups of native speakers took the Speeded GJT at three different presentation rates to examine whether native speakers under a processing burden perform similarly to learners. Natives in the fastest speed performed better with feature clash errors for both gender and number. Learners showed the same pattern for number, but performed better with default errors in gender, suggesting different effects of processing demands for properties unique to the L2. On the Untimed GJT, a subset of advanced learners showed perfect performance with both gender and number.

The Aesthetic

This book is the first history of keyboard improvisation in European music in the postclassical and romantic periods (c. 1815–1870). Grounded in primary sources, it documents practices of improvisation on the piano and the organ, with a particular emphasis on free fantasies and other forms of free playing. Case studies of performers such as Abbé Vogler, J. N. Hummel, Ignaz Moscheles, Robert Schumann, Carl Loewe, and Franz Liszt describe in detail the motives, intentions, and musical styles of the nineteenth century’s leading improvisers. The book further discusses the reception and valuation of improvisational performances by colleagues, audiences, and critics, which prompted many keyboardists to stop improvising. Its central argument is that amid the decline of improvisational practices in the first half of the nineteenth century there emerged a strong and influential “idea” of improvisation as an ideal or perfect performance. This idea, spawned and nourished by romanticism, preserved the aesthetic, social, and ethical values associated with improvisation, calling into question the supposed triumph of the “work.”

The Magnetic Field

This new dry magnetic separator has a special structure. It has many magnetic roll which are staggered like a stairsteps. It can finish the task of separating different minerals with only this one machine. And also it can make the different magnetic material which are in the same mineral separate at the same time. The permanent magnet system is made of large fan-shaped magnet. The magnet pole N and S are staggered and has perfect performance of magnetic separation. And the magnetic force is made full use by going-up dynamic separation. And also it gives an analysis of stress in the magnetic field. It also shows that its separation idex is better, the economic benefits are obvious, and it has broader prospects of popularization and application.

Perfect Performance

Praxis was defined as the ability to perform skilled movements on command or demonstration. The performances of 87 normal male children, ages 1 to 6 yr., were assessed on four measures of praxis: oral praxis command, oral praxis demonstration, limb praxis command, and limb praxis demonstration. These measures were also correlated with measures of language and articulation development for the entire group across ages and for yearly age intervals. Results showed an orderly emergence of praxis in all measures beginning about age 1 and reaching nearly perfect performance by age 6. Predictably, ability to follow demonstration emerged earlier than ability to follow spoken commands. Praxis correlated somewhat with articulation and language skills at age 2 but the magnitude of the correlations decreased with increasing age intervals. Normative data are provided for clinical researchers interested in studying “apraxic” children.

A new type of squeeze film damper (SFD) is designed to reduce spool’s impact and vibration which happen in the two-stage larger flow rate high-speed on/off valve with the 450 L/min flow rate and 8ms turn-off time, the valve’s sealing performance、reliability and service life improve largely, and the valve’s response speed doesn’t drop. The simulated and experimental results show: The damper has optimum buffering performance when oil film thickness is 0.1mm, and the spool closing process approach ideal state. The valve will has a great potential application in the powerful occasions because of it's perfect performance: larger flow rate、fast response and novel damper.

Abstract The performance of a simple slot is perfect, but it does not have structural integrity. A new advanced cooling scheme with perfect performance and practical structural integrity is presented. Based on the crucial effect of the counter-rotating vortex pair (CRVP) on the film cooling effectiveness (η), the new scheme is composed of a comb-like structure and a blind slot, in which the comb structure maintains the mechanical strength, and the blind slot is intended to eliminate the CRVP and produce a smooth coolant film. The new scheme is investigated experimentally with the transient thermochromic liquid crystal (TLC) technique. Two classic geometries, the cylindrical hole and the simple slot, were also measured. The agreement of their results with the published data validated the present experimental facilities. The experimental results of the Comb scheme demonstrated that, with practical structural integrity, the new scheme has perfect performance, which bears comparison with the simple slot. Consequently, the success of the Comb scheme proved the crucial CRVP effect on η.

Bridge bearings are the structural members which are installed at the connection between superstructure and substructure in a bridge. They are expected to transfer load between superstructure and substructure, and to accommodate expansion and rotation of superstructure due to live load and temperature change. Bridges are designed based on whole structure models in which bearings show perfect performance. If bearings are deteriorated, the structure system of the whole bridge should be changed, and some damage may occur in superstructure and substructure. Therefore, it is of great importance to maintain bearings in good conditions. In this study, we try to establish quantitative evaluation method for required basic functions (load supporting, horizontal moving and rotating function) of bridge bearings as the structural member, through measuring displacement and stress in several highway bridges in the north area of Japan.
