SecA, the preprotein translocase ATPase is built of an amino-terminal DEAD helicase motor domain bound to a regulatory C-domain. SecA recognizes mature and signal peptide preprotein regions. We now demonstrate that the amino-terminal 263 residues of the ATPase subdomain of the DEAD motor are necessary and sufficient for high affinity signal peptide binding. Binding is abrogated by deletion of r...

This paper presents the design of digital controller for a BLDC motor to control the speed and position control using Digital Signal Processor (DSP) TMS320LF 2407 which is used in an Electromechanical Actuator. Brushless D.C motor (BLDC) are one of the motor types rapidly gaining popularity. This motor offer a simple and rugged motor Solution for many variable speed drive application. Rotation ...

In this paper, a high performance of fuzzy logic controller for DC servo motor is developed. The system design and implementation procedure of DC servo motor drive using digital signal processing chip TMS320C14 are described. Some experimental results are shown to verify the proposed controller. Key-Words: Fuzzy logic controller, Digital signal processing, DC servo motor

Speed/accuracy trade-off is a ubiquitous phenomenon in motor behaviour, which has been ascribed to the presence of signal-dependent noise (SDN) in motor commands. Although this explanation can provide a quantitative account of many aspects of motor variability, including Fitts' law, the fact that this law is frequently violated, e.g. during the acquisition of new motor skills, remains unexplain...
