In recent years, the global warming and efficient usage of energy sources are become most attractive issues. Furthermore, renewable energy technologies play an important role in addressing global energy and environmental challenges. Among the renewable energy technologies, hydropower is considered to be the most advanced and mature, providing some level of electricity generation in more than 16...

Waterwheels are the oldest types of hydraulic machines. These turbines are of relatively simple design, large diameter, low rotational speed and high torques. But applying them as micro hydros of high speed and small diameter is yet to be explored. A micro hydro waterwheel of one meter diameter was designed and manufactured at the Iranian  esearc†h Organization for Science and Technology (IROST...

We study the thermodynamic efficiency of Malkus-Lorenz waterwheel. For this purpose, we derive an exact analytical formula that describes dissipative structure as a function phase space variables and constant parameters dynamical system. show that, generally, machine is progressively driven far from equilibrium by increasing its uptake matter environment, it also tends to increase efficiency. H...

In the present paper a model is presented for the dynamic response of a family (Droseraceae) of carnivorous plants such as the Venus Flytrap (Dionaea Muscipulu Ellis) and the Waterwheel Plant (Aldrovanda Vesicuha) to external dynamic disturbances. The goal of the present investigation is to apply such modelling to the molecular design of biomimetic materials with sensors and actuators. In model...

An analysis of map charts Upper Silesia from the second half 18th century allows us to identify at least a few lost settlements and hamlets. There is no doubt that one such settlement existed upon Bierawka river, in vicinity present-day villages Trachy (Althammer) Tworóg Mały (Quarghammer). Regrettably, exact location this has never been identified. archival query test excavations demonstrated ...
