We describe our experiences using Python with the SPaSM molecular dynamics code at Los Alamos National Laboratory. Originally developed as a large monolithic application for massively parallel processing systems, we have used Python to transform our application into a flexible, highly modular, and extremely powerful system for performing simulation, data analysis, and visualization. In addition...

Modelica has evolved as a powerful language for encoding models of complex systems. In control engineering, it is of interest to be able to analyze dynamic models using scripting languages such as MATLAB and Python. This paper illustrates some analysis and design methods relevant in control engineering through scripting a Modelica model of an anaerobic digester model using Python, and discusses...

Roads are significant objects of an infrastructure and the extraction of roads from aerial and satellite images are important for different applications such as automated map generation and change detection. Roads are also important to detect other structures such as buildings and urban areas. In this paper, the road extraction approach is based on Active Contour Models for 1-meter resolution g...

Accurate blood vessel segmentation plays a crucial role in non-invasive blood flow velocity measurement based on complex-valued magnetic resonance images. We propose a specific snake active contour model-based blood vessel segmentation framework for complex-valued magnetic resonance images. The proposed framework combines both magnitude and phase information from a complex-valued image represen...

Since a snake achieves various movements just by a slender body, the mechanism of it is very amazing Many researches have been focusing on a snake like robot and have done for it on the ground. However the meander motion of the snake not only can be done by ground creatures, but also can be done by a water creature such as a sea snake or an eel. Therefore, the purpose of our research is to deve...

Problem statement: In snake robot research, one of the most efficient forms of locomotion is the lateral undulation. However, lateral undulation, also known as serpentine locomotion, is illsuited for narrow spaces, as the body of the snake must assume a certain amount of curvature to propel forward. Approach: To overcome the inability to adapt to narrow spaces, a novel type of a gait was introd...

Studies of event-related potentials in humans have established larger early posterior negativity (EPN) in response to pictures depicting snakes than to pictures depicting other creatures. Ethological research has recently shown that macaques and wild vervet monkeys respond strongly to partially exposed snake models and scale patterns on the snake skin. Here, we examined whether snake skin patte...

ABSTRACT Dot-ELISA test is developed in mice models to identify cobra and viper snake species in snake bite cases. Simplicity and cost effective qualities of this test showed great promises to be utilized in the field which can be useful for farmers, plantation workers and fisherman who are working in field and become victim of snake bite cases. Dot-ELISA test can be an alternative solution to ...

E nvenoming resulting from snake bites is an important public health hazard in many regions, particularly in tropical and subtropical countries [1–3]. Although antivenoms are being produced by various laboratories in every continent, the burden of snake bite envenoming— causing both morbidity and mortality—still has a great impact on the population and on health-care systems, especially in Afri...

In nature, snakes can gracefully traverse a wide range of different and complex environments. Snake robots that can mimic this behaviour could be fitted with sensors and transport tools to hazardous or confined areas that other robots and humans are unable to access. In order to carry out such tasks, snake robots must have a high degree of awareness of their surroundings (i.e., perception-drive...
