W pracy wyznaczono czasowe przebiegi sił mięśniowych kończyn dolnych za pomocą modelu matematycznego u sportowca wykonującego pchnięcie kulą. Szczegółowo przedstawiono proces generowania symulacji w programie OpenSim na podstawie danych pochodzących z systemu Vicon Nexus. Zdefiniowany model ukazał, które mięśnie generują największą siłę w trakcie wykonywania ruchu pchnięcia kulą oraz które mięśnie pracują w warunkach ekscentrycznych. Istnieje możliwość wykorzystania wygenerowanego modelu do dalszych symulacji mających na celu szczegółową analizę techniki wykonywania pchnięcia kulą.

Time trajectories of muscle forces for an athlete performing the shot put were modeled in the following article. The process of generating simulation in OpeSim software based on Vicon Nexus system data was presented in detail. The generated model showed which muscles generate the highest force while performing the movement of the shot put. It was also presented which muscles are working in eccentric conditions, which may cause injury. There is a possibility to use the generated model for further simulations, in order to conduct detailed analysis of shot put technique.

This article shows step by step process of creating general algorithm saying how to implement continuous flow in production companies. Article is based on real environment of medium Polish production company, which produces steel halls. After presenting basic information about TOC and LEAN tools it shows and algorithm showing activities and sequence made in real company. Authors proposed solutions referred to both the material flow changing's and the information flow changing's. Main goal was adapt production process to unchangeable work of bottleneck. After all, results of production flow simulation after implementation of above solutions were presented. Finally, authors created algorithm based on techniques and tools implemented in mentioned company. It shows in general what production engineers should do step by step while implementing continuous flow in production.

Dynamic programing is one of the major problem-solving methodologies in a number of disciplines such as operations research and computer science. It is also a very important and powerful tool of thought. But not all is well on the dynamic programming front. There is definitely lack of commercial software support and the situation in the classroom is not as good as it should be. In this paper we take a bird's view of dynamic programming so as to identify ways to make it more accessible to students, academics and practitioners alike.
