Purpose We propose a system capable of detecting articulated surgical instruments without the use of assistive markers or manual initialization. Methods The algorithm can provide 3D pose using a combination of online and offline learning techniques along with prior geometric knowledge of the tool. It uses live kinematic data from the robotic system to render nearby poses on-thefly as virtual im...

In a wireless sensor network (WSN), the unbalanced distribution of communication loads often causes the problem of energy hole, which means the energy of the nodes in the hole region will be exhausted sooner than the nod...

Mycotoxins present in fodders may evoke health problems of animals and people. The data published by FAO in 2001 show that 25% of raw materials are contaminated with mycotoxins, while their type and concentration are to a great extent dependable on the climatic zone. Biological detoxification of mycotoxins by the use of microorganisms is one of the well-known strategies for the management of my...

This paper analyzes how organizational culture is intertwined with usability work in software (SW) development organizations. Usability is an important quality characteristic of software products and systems. However, the development of usability is challenging in SW development. Organizational culture has been argued to affect usability work in SW development organizations, thus, this paper ta...

MOTIVATION Natural language processing (NLP) techniques are used to extract information automatically from computer-readable literature. In biology, the identification of terms corresponding to biological substances (e.g., genes and proteins) is a necessary step that precedes the application of other NLP systems that extract biological information (e.g., protein-protein interactions, gene regul...
