Inverted pendulum models are commonly used to study the bio-mechanics of biped walkers. In its simplest form, the inverted pendulum consists of a point mass attached to two straight mass-less legs. Most works constrain the motion of the mass to the sagittal plane, i.e. the plane perpendicular to the ground that contains the direction toward the biped is walking. In this article, we remove this ...

The purpose of the study was to ascertain the basic morphologic and kinematic characteristics of elite sprinters. The sample included 24 sprinters, with times over a 100 m distance between 10.21 s and 11.19 s. Morphologic characteristics of the sprinters were measured with a test battery of 17 measures, obtained according to the methodology prescribed by the International Biologic Programme (IB...

Abstract Paper cultural relics such as double-sided printed newspapers and periodicals represent modern heritage. Severe damage embrittlement, decay, dreg generally occur to paper; hence, it urgently needs conservation restoration. Therefore, herein, a new reinforcement method for the fragile paper is proposed with cotton mesh adhesive PVA217 materials. Using computer measured controlled foldin...

An important wood species in the furniture and parquet industry today is “doussie” wood. In this study, effects of artificial weathering on ultraviolet-cured varnish (3 coats 5 coats) applied to doussie (Afzelia africana) were investigated. The samples UV system cured varnishes exposed aging for 252 h 504 via an UV-A 340 nm lamp. coated specimens fluorescent lamp a QUV accelerated tester h. sur...

Pavement surface texture and its skid resistance are two key safety parameters of highways, which both are influenced by pavement characteristics. This research is done on a newly constructed asphalt pavement (Qom-Garmsar freeway) in Iran. The goal is investigating the relation between skid resistance and pavement texture in order to asphalt content changes in Hot Mix Asphalt. Mean Texture Dept...

ted to the favourable consideration of British Surgeons by its distinguished advocate, Sir Henry Thompson, as the best method of dealing with very large stones in adult males and youths, it was suddenly seized upon by a number of: in-experienced lithotomists, as the safest method in their hands, of dealing with small stones in male children, and the good old lateral lithotomy which had stood th...

The paper reports new findings about Galileo’s experiments with pendulums and discusses their significance in the context of Galileo’s writings. The methodology is based on a phenomenological approach to Galileo’s experiments, supported by computer modelling and close analysis of extant textual evidence. This methodology has allowed the author to shed light on some puzzles that Galileo’s experi...
