Drilling Rig Operation Mode Recognition by an Artificial Neuronet

Ergonomic Exposure Assessment on a Drilling Rig

An Hybrid Mode of Operation

In this paper I propose a tweakable block cipher construction with a mode of operation that combines counter and chaining methods. Using a single key, the direct application of this mode produces unrepeatable message authentication tags.

Pattern Recognition by an Artificial Tactile Sense

This paper proposes an a r t i f i c i a l t ac t i l e pattern recognition system, which combines recognit ion by touching the object surface with an a r t i f i c i a l tac t i l e sense and recognition by grasping the object with an a r t i f i c i a l hand. The inspirat ion for this proposition was found in the function of the tac t i l e sense of a human hand. The fundermental pr inciple o...

Structural Insights into RNA Recognition by RIG-I

Intracellular RIG-I-like receptors (RLRs, including RIG-I, MDA-5, and LGP2) recognize viral RNAs as pathogen-associated molecular patterns (PAMPs) and initiate an antiviral immune response. To understand the molecular basis of this process, we determined the crystal structure of RIG-I in complex with double-stranded RNA (dsRNA). The dsRNA is sheathed within a network of protein domains that inc...
