Individuals with below knee amputation exert more effort during walking than their able-bodied counterparts [1]. This increased effort may partially be due to increased balancerelated effort, especially while walking on challenging terrain [2]. Recently, we found that balance-related effort can be reduced by modulating ankle push-off work with a robotic ankle-foot prosthesis [3]. In doing so, w...

Payment channel networks use off-chain transactions to provide virtually arbitrary transaction rates. In this paper, we provide a new perspective on payment channels and consider them as a flow network. We propose an extended push-relabel algorithm to find payment flows in a payment channel network. Our algorithm enables a distributed and concurrent execution without violating capacity constrai...

The author attempts to formalize the role of push and pull factors in rural-urban migration and urban unemployment in Pakistan. Based on the Harris-Todaro framework, a model is developed that also includes perpetual indebtedness of the peasantry and a monopolistic moneylender. The analysis indicates that measures to control such migration could fail because the moneylender siphons off part of...

This is the summary of the research being done at Cal Poly Pomona at an undergraduate level on the development of obstacle avoidance capability for unmanned aerial vehicles (UAVs). A quadrotor UAV is used as the research platform. Push and Rapidly Exploring Random Tree (RRT) algorithms are used for the obstacle avoidance capability. The paper shows the use of cheaper commercial off-the-shelf se...

the objective of this study was to determine the effects of grasp conditions (types of grasp, grasp width, glove and types of coupling) on maximal pushing force (mpf) and required pinch force (rpf) during snap fit assembly. the results indicated that the type of grasp, the type of coupling and wearing gloves have significant (p

Push-based data delivery requires knowledge of user interests for making scheduling, bandwidth allocation, and routing decisions. Such information is maintained as user profiles. We propose a new incremental algorithm for constructing user profiles based on monitoring and user feedback. In contrast to earlier approaches, which typically represent profiles as a single weighted interest vector, w...

The human foot evolved to provide: (1) mechanisms to limit the excursion of the center of mass during ambulation and thereby minimize the expenditure of energy; (2) a base of support of sufficien dimensions for the stability necessary to maintain the upright position without excessive muscular activity; (3) mechanisms for flexibility to absorb the shock of the body weight and for accommodation ...

In the paper, a special approach to supply networks’ material flows is posed. The considered strategy is based on the both principles of Lean and agility, beside push and pull of materials. Here, the trade off between positioning of decoupling point throughout an exemplary network, and reduction of inventory level along throughput time is examined. Moreover, autonomous control for material rout...
