Objective: To report defection of phalanx under the reconstructed pulleys with Bunnell’s technique. Methods: We followed up 26 reconstructed annular pulleys in 23 digits of 18 cases for 20 months and analysed the X-ray results of those phalanges. The function of pulley reconstruction was observed. The joint flexion and extension movement of the finger joint was recorded. Results: All the recons...

An articulated leg for the use in a running robot is presented. It is driven by series elastic actuation with a highly compliant spring at the knee joint to exploit periodic energy storage and passively support a running motion. The spring is connected with the knee motor by a cable pulley system, which allows the advantageous placement of the motor in the hip joint and enables us to use a comp...

In the V-belt drive system, temperature and humidity are the most effective parameters affecting the slippage. This study is done in two stages. Firstly, experimental study has been carried out and the effect of temperature, relative humidity on the slippage between V-belt and pulley has been analyzed. At the second stage, non-linear regression analysis has been carried out to get a prediction ...

In the present study we hypothesized that the gist representation of a picture (extracted from brief initial inspection) supports inference generation from subsequent text, which in turn should foster comprehension. Moreover, we proposed that longer inspection of a picture is necessary to provide learners with an alternative representation that fosters mental animation and recall. Participants ...

Now a day’s Belt conveyor system not only used in mining industries but also applied in cement industries, power plant, food industries, production industries etc. So it is essential equipment for in house material transportation today. The paper presents the review of belt conveyor design modification and latest technologies or methodologies used in different applications to reduce failures, m...

Reaction-time and eye-fixation data are analyzed to investigate how people infer the kinematics of simple mechanical systems (pulley systems) from diagrams showing their static configuration. It is proposed that this mental animation process involves decomposing the representation of a pulley system into smaller units corresponding to the machine components and animating these components in a s...

This thesis documents my personal contribution to the development of a hydraulic-based actuation system for a solar trough collector. The goal of this project was to design the actuation system using hydraulic actuators for a four meter solar collector prototype in Pittsfield, New Hampshire. After considering several hydraulic system architectures and conducting in-depth analysis into two of th...

Arthroscopic Bankart repair is now a well-established technique for the treatment of shoulder instability. However, failure rates are considerable when significant bony defects are not addressed. Hill-Sachs lesions, present in the vast majority of those with recurrent anterior instability, when of significant dimension and location, may account for some of these failures. The remplissage proced...

This paper discusses a novel method to compensate the eeects of exibil-ity in belt-driven drive trains. Such drives are found in robot manipulators, for example, where drive exibility is undesirable. In some situations, band-width limitations can make exibility diicult to compensate using the primary actuator. In others, the control for the primary actuator is pre-deened and cannot be easily al...

Abs tract. The authors have developed a web-based production system that users can use whenever and anywhere by the Internet. The authors held two cognitive science introductory classes with the system. In our class activities, participants were required to construct running cognitive models on the production system architecture that can solve pulley problems. The participants not only construc...
