Abstract. This paper describes the study of dynamic stability a hydrofoiling sailing boat called “Goodall Design Foiling Viper”. The goal Goodall is to make accessible wider public, whereas it was previously reserved for professional sailors at highest level sport. To allow safe operation, an essential characteristic boat. aim this work find strategy perform analysis using computational fluid d...

The increase of anthropogenic noise in the environment is a global phenomenon occurring various types habitats. Its impact on wildlife therefore growing research concern for many taxa. Due to their amphibious lifestyle, pinnipeds are exposed both aquatic and terrestrial environments. Using playback experiments, present study assessed engine (car boat) behaviour Cape fur seals at Pelican Point b...

In the present study, authors have attempted to a novel approach for prediction, analysis, and optimization of Friction Stir Welding (FSW) process based on Deep Neural Network (DNN) model. To obtain DNN structure with high accuracy, most focus has been number hidden layers activation functions. The was developed by small database containing results tensile hardness tests welded 7075-T6 aluminum...

Ataxin-1 is a neurodegenerative disorder protein whose glutamine-repeat expanded form causes spinocerebellar ataxia type 1 (SCA1) in humans and exerts cytotoxicity in Drosophila and mouse. We report here that the cytotoxicity caused by ataxin-1 is modulated by association with a related protein, Brother of ataxin-1 (Boat). Boat and ataxin-1 share a conserved AXH (ataxin-1 and HMG-box protein 1)...

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...

A high strength nickel chromium alloy (50Cr-50Ni-Nb alloy), commonly referred to as IN-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. The purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of Inconel 657. The considered parameters...

In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...

Superior electronic properties of graphene make it a substitute candidate for beyond-CMOSnanoelectronics in electronic devices such as the field-effect transistors (FETs), tunnel barriers, andquantum dots. The armchair-edge graphene nanoribbons (AGNRs), which have semiconductor behavior,are used to design the digital circuits. This paper presents a new design of ternary half a...
