In this paper a new method for the registration of trunk movements is presented. With this method, called the Portable Posture Registration Set (PPRS), movements can be recorded continuously over a long period of time. The purpose of this study was to test whether the PPRS can be applied in golf. A pilot study using 4 male golfers demonstrated that qualitative and quantitative data on trunk movements in golf can be collected with the PPRS. The inclination of the trunk proved to be large (40–45°) in all swings tested, resulting in a considerable load on the back. The contribution of torsion to the spinal load was relatively small, especially in the putt, which showed very little movement in the transverse and frontal planes. However, putting accounted for most of the total spinal load in playing a course. Even when playing a round of 18 holes, subjects did not experience any hindrance or discomfort from the sensors or the recorder. This method seems to offer new possibilities in the biomechanical study of trunk movement in golf.

In this paper, a new method of baseline correction on strong motion acceleration records is presented and the fundamental concept for baseline corrections on the earthquake strong motions is described. Considering the filtering effect, the earthquakes ground motion displacements of 1995 JMA KOBE, 1999 Kocaeli YPT and 1999 Chi-Chi TCU068 are discussed. Also, the linear sloshing responses of large liquid tanks subjected to these motions were discussed. Since liquid storage tanks show the low frequency (long period) sloshing characteristics and the strong motion characteristics of 1999 Kocaeli and Chi-Chi earthquakes are also low frequencies and large permanent displacements, the sloshing responses in large liquid tanks, especially in long natural periods, were significantly affected by the low frequency motions (large permanent displacements) of these devastating earthquakes. It is very important to use suitable ground motion characterized low frequency content for earthquake resistant design of liquid storage tanks. The baseline correction method presented in the paper may be adequately used to correct strong motion records for large liquid storage design.

AbstractThe 50 year time series of mass balance on Glacier de Sarennes is one of the longest in the French Alps, and so is often used as a reference for glacier variations in the French Alps. Meteorological data can be used to extend the series backwards in time. Martin (1978) proposed such a reconstruction for the 1882–1977 period. With 50 years of observations, we show that the classical method used by Martin is too dependent on the calibration period. We therefore try to improve the accuracy of this reconstruction using the Vincent and Vallon (1997) method which takes into account the albedo change of the surface during the ablation period (this is called the daily method). This new method appears to be stable in time. Once calibrated, the daily method is applied to reconstruct the 1881–1949 period. The new reconstruction is compared to a volumetric balance between two maps from 1906 and 1981. It appears that both reconstructions (classical and daily) fail to render the trend correctly over a long period of time. The cumulative centred mass balance correlates well (r2 = 0.62) with the hydrological mass-balance series of Aletschgletscher, Switzerland.

AbstractWe are monitoring nearby long period variable stars (LPVs) in the near infrared K band to establish their precise Period-Luminosity relation. However, they are very bright in the near-infrared and it is difficult to observe them because they are easily saturated on the modern near-infrared camera. We developed a special ND filter, named Local Attenuation Filter (LAF), to observe very bright stars. Using LAF, we can observe not only the very bright targets without saturation but also reference stars in the same image. We can perform the accurate relative photometry for the bright stars. We present this new method to observe bright stars as well as the status of our monitoring of nearby LPVs.

Based on observations, tofu home industry in several places in the city of Jakarta still uses conventional production methods. The printing and press process using conventional methods takes a long time the equipment used to print and press tofu is teak. According to home industry owners know to press 100 tofu in one container takes about 20 minutes. The process of producing tofu with a conventional system is less effective and efficient because it requires a long period of time. Based on these problems, the aim of this project is to socialize the new method of using the Automatic Tofu Press Tool so that it is useful in providing knowledge to the SME (Small Medium Enterprise) tofu community about more efficient and shorter press processes, and produces uniform production of both the texture and thickness of tofu produced.

According to the Chinese Structure Code and engineering experience, the factors affecting the reliability of structures are properly qualified as input parameters; this paper mainly researches the application of neural networks in the reliability evaluation of structures. Comparisons are made between the traditional methods of reliability evaluation of established structures and the method put forward in this paper. It is found that the method put forward in this paper is practicable, reliable and effective. Meanwhile, the weaknesses of the traditional reliability evaluation of structures, that is, long period of evaluation, huge and tedious calculation and arbitral judgments, are avoided with the introduction of the new method in this paper.
