Consider the Newtonian potential of a homogeneous bounded body D ⊂ R3 with known constant density and connected complement. If this potential equals to c/|x| in a neighborhood of infinity, where c > 0 is a constant, then the body is a ball. This known result is now proved by a different simple method. The method can be applied to other problems.

This study examined differences in center of pressure (COP) trajectories between shod and barefoot running. Ten habitually shod runners ran continuous laps under both shod and barefoot conditions. The COP trajectory was calculated in the global coordinate system but then transformed to the anatomic coordinate system of the foot. The anterior-posterior and medio-lateral positions and excursions ...

This paper revises notions related to Language Resources and Technologies (LRT), including a brief overview of some resources developed worldwide and with a special focus on Romanian language. It then describes a joined Romanian, Moldavian, English initiative aimed at developing electronically coded resources for Romanian language, tools for their maintenance and usage, as well as for the creat...

In this paper we describe how a robotic arm can acquire new skills, and specifically how to play beer pong. We used two different optimization algorithms are described and applied to teach a robot how to play the game beer pong. The first algorithm is the gradient based finite difference method. The second one is the expectation maximization algorithm PoWER. Their performance, consisting of bot...

Sports injuries fall into two general types. Acute traumatic injuries occur suddenly and usually involve a single application of force, for example, a hard tackle in football. They include fractures, breaks, bruises, sprains, strains and abrasions. Chronic or overuse injuries, by contrast, happen over a period of time. These injuries are usually the result of training that involves repetitive m...

Enumeration algorithms in lattices are a well-known technique for solving the Short Vector Problem (SVP) and improving blockwise lattice reduction algorithms. Here, we propose a new algorithm for enumerating lattice point in a ball of radius 1.156λ1(Λ) in time 3n+o(n), where λ1(Λ) is the length of the shortest vector in the lattice Λ. Then, we show how this method can be used for solving SVP an...
