The article describes the inflow turbines as reliable, productive, small-sized drives for various units and devices. practice of manufacturing using turbine stages sets out goal increasing efficiency, simplifying technology reducing cost stages. Increasing efficiency requires solving problems improving flow part calculating optimal geometry operating modes impeller flow. A significant low-consu...

Experimental tests in prototype are necessary to understand the dynamic behaviour of the machine during different operating points. Hydraulic phenomena as well as its effect on the structure need to be studied in order to avoid instabilities during operation and to extend the lifetime of the different components. For this purpose, a complete experimental study of a large Francis turbine prototy...

This paper presents the software package developed at Fluid and Power Research Institute (FPRI) for the uid mechanical design of the wicket gates and the runner blades of the Potential Flow turbine [1]. This software package is based on the correct formulation of the design problem. The design problem can not be correctly formulated for Francis and Kaplan turbines with conventional wicket gates...

We study the strategic interaction between fundamental informed trading and order-flow informed trading. In a standard two-period Kyle (1985) model, we add a “back-runner” who observes, ex post and potentially with noise, the order flow of the fundamental informed investor in the first period. Learning from orderflow information, the back-runner competes with the fundamental investor in the sec...

INTRODUCTION This note engages in the public debate over the participation of female athletes with hyperandrogenism in professional sport. Hyperandrogenism, a condition leading to higher testosterone levels than would be expected for ‘biological females’, is thought by many to provide affected athletes with a competitive edge over non-affected athletes.1 In 2011, when public attention was drawn...

Modelling and simulation of injection moulding process is an important technique that could shorten production cycle time with improved productivity for defect-free parts. This technique is more suitable for micro-injection moulding (μIM) process as likely defects during production can be predicted. Therefore, this study aims to investigate the effect of runner dimensions on quality of moulded ...

The hypothesis that there may be something quantum-like about the human mental function was put forward with “Spooky Activation at Distance” formula which attempted to model the effect that when a word’s associative network is activated during study in memory experiment; it behaves like a quantumentangled system. The human body is a constant flux of thousands of chemical/biological interactions...

Testing automation tools enables developers and testers to easily automate the entire process of testing in software development. The objective of the paper is to conduct a comparative study of automated tools such as the Mercury Quick Test Professional and the Mercury Load Runner based on criteria such as the efforts involved with generating test scripts, capability to playback the scripts, re...

Cross-flow turbines have recently been proposed for energy recovery in aqueducts when the outlet pressure is greater than zero, owing to their constructive simplicity and good efficiency within a large range of flow rates head drops. In case high drop (higher 150 m) relatively small discharge (lower 0.2 m3/s), traditional design these leads very widths nozzle runner; as consequence, friction lo...
