Scientists cannot easily make use of numerical data encoded in plot images, such as spectroscopy data, scientific literature. Plot2Spectra was developed to computer vision tools automatically digitize images.

The paper presents a new method for on-line temperature calculation taking into account change in the tap changer position. The method introduces accurate calculation of the losses, depending on the current, average temperature of the winding, and tap changer position (it affects both Joules (DC) losses and stray losses). The thermal model itself is the common three-body model (for a transforme...

for the performance improvement and higher flexibility in irrigation networks, applications of automatic systems are expanding and on evaluation of their success for achieving the objectives are essential and necessary. considering various equipment, algorithms, and their applications at different levels of irrigation networks, the performance of automatic systems is a function of the performan...

In the traditional port, disengaging hook system adopts a three-phase power frequency power to drive a three-phase asynchronous motor. The operation is simple and the maintenance is convenient. However, it still keeps the speed of mooring lines constant. Under the light-load condition, the work efficiency could be affected because of the low speed. To solve this problem, we start the research i...

This paper introduces a new speech design tool (Sesign99) that can convert monotonous synthesized speech into a variety of speech styles. As multimedia services such as games, interactive movies and WWW home pages become more popular, more attention is being focused on the creation, management, and transmission of speech messages. Although speech synthesis-by-rule has improved with recent advan...

Virtual Reality (VR) provides users advanced visualization and interaction technology for designing, analyzing and exploring complex data. To address the issue of noise in manufacturing environments, we developed a VR-supported method allowing users to explore noise behavior. This method consists of an implementation of acoustic simulation and visualization for both desktop and Cave Automatic V...

C 2012 American Chemical Society Graphene: The Game Changer? I t has only been eight years since the isolation of graphene 1 and over a year since the 2010 Nobel Prize in Physics was jointly awarded to Andre Geim and Konstantin Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene.” Nevertheless, the number of graphene publications is still rapidly growing. T...

wants to make the transition between medical school and residency seamless. A lthough she no longer heads a medical school, Deborah Powell is making a mark on medical education. She's trying to break down the wall between medical school and residency and wants to see students trained in a way that's practical , efficient and better reflects the way medicine is practiced today. " Medicine has ev...

Design and implementation of an automatic three phase changer using LM324 quad integrated circuit was carried out. The system was designed and simulated using (Multisim). The circuit components were mounted a Vero board. LM324 integrated circuit (comparator) and 2N2222 transistors were used as active components alongside other passive components. Result shows that, when the three phase a.c inpu...
