Adaptive output feedback neural network control of uncertain non-affine systems with unknown control direction

This paper deals with the problem of adaptive output feedback neural network controller design for a SISO non-affine nonlinear system. Since in practice all system states are not available in output measurement, an observer is designed to estimate these states. In comparison with the existing approaches, the current method does not require any information about the sign of control gain. In order to handle the unknown sign of the control direction, the Nussbaum-type function is utilized. In order to approximate the unknown nonlinear function, neural network is firstly exploited, and then to compensate the approximation error and external disturbance a robustifying term is employed. The proposed controller is designed based on strict-positive-real (SPR) Lyapunov stability theory to ensure the asymptotic stability of the closed-loop system. Finally, two simulation studies are presented to demonstrate the effectiveness of the developed scheme.

Anticipatory postural adjustments during cutting manoeuvres in football and their consequences for knee injury risk

Abstract

Anticipatory postural adjustments (APAs), i.e. preparatory positioning of the head, the trunk and the foot, are essential to initiate cutting manoeuvres during football games. The aim of the present study was to determine how APA strategies during cutting manoeuvres are influenced by a reduction of the time available to prepare the movement.

Thirteen football players performed different cutting tasks, with directions of cutting either known prior to the task or indicated by a light signal occurring 850, 600 or 500 ms before ground contact.

With less time available to prepare the cutting manoeuvre, the head was less orientated towards the cutting direction (P = 0.033) and the trunk was even more rotated in the opposite direction (P = 0.002), while the foot placement was not significantly influenced. Moreover, the induced higher lateral trunk flexion correlated with the increased knee abduction moment (r = 0.41; P = 0.009).

Increasing lateral trunk flexion is the main strategy used to successfully perform a cutting manoeuvre when less time is available to prepare the movement. However, higher lateral trunk flexion was associated with an increased knee abduction moment and therefore an increased knee injury risk. Reducing lateral trunk flexion during cutting manoeuvres should be part of training programs seeking the optimisation of APAs.     

南京市不同类型扬尘源排放清单估计

运用美国环保署AP-42方法及观测资料,估算2010年南京市土壤扬尘、铺装道路扬尘和城区施工扬尘的排放,并给出3 km×3km分辨率的空间分布.研究结果表明,3类扬尘PM₁₀排放分别为0.0261、6.727、0.754万t.铺装道路扬尘的贡献最大,从市区向南北城郊方向,排放逐渐减少.比较而言,南京市3类扬尘PM₁₀的排放总量小于上海,约相当于本市工业排放的67.3%.     

汉代海上丝绸之路出土金珠饰品的考古研究

参照国内外学者对中国大陆出土金珠饰品的研究成果,对南海沿岸汉墓历年所出金花球等饰品进行比较研究,可以得出如下认识:合浦金珠饰品体现出域外风格,它在南海一带流行的年代主要是在东汉时期,当与以海上丝绸之路为代表的南海一带经济文化交流有密切关系;但从金珠焊接方法等制作工艺判断,这种产品本身是舶来品还是汉地产品,还存在疑问。从考古发现判断,金珠饰品有在合浦当地制作的可能性。     

隋唐时期丝绸之路贸易管理政策析论

＂丝绸之路＂是汉代张骞通西域以后中国与外界联系交往的主要通道之一。隋唐时期是丝路贸易发展的黄金时期。隋朝采取军事和政治方针,拓展西北疆域,建立对西域发展贸易的商镇、军镇;派重臣裴矩在河西走廊进行招商活动,扩大隋与西域、中亚、波斯的经济联系,积极发展丝路贸易。唐朝在＂安史之乱＂之前的将近一个半世纪中,以强大的军事、政治、经济力量保障了丝路的畅通。中原政府在丝路广设驿站、推行＂过所＂、＂公验＂等制度,其丝路贸易管理政策在隋朝基础上有所完善和发展,直接推动了丝路贸易的全面繁荣。
