In the applications of parallel manipulators, kinematic calibration is required to eliminate the errors resulting from the manufacturing and assembly of both base and tools. In this paper, a calibration method of base and tool transformation is developed by virtue of optical position sensors. An error model for calibration is constructed using differential geometry method. The pose error is obt...

Control of a space robot is difficult as its base is not fixed. Due to this any motion of joints gives a reactive motion of the base. This changes the attitude and position of the base. Change of position of the base of space robot is not a problem as minor movements are permissible but the change of attitude seriously affects the orientation of antenna, solar panel. This work presents the tip ...

be interpreted in the base position of movement. The argument is based on a study of deletion of a phrase that contains the base position of movement. I show that deletion licensing is sensitive to the content of the moved phrase. In this way, I corroborate and extend conclusions based on Condition C reconstruction by N. Chomsky and D. Fox. My result provides semantic evidence for the existence...

Determining one’s current position using only the information received from WLAN base station access points is a challenging task. Several positioning systems with a varying degree of complexity have been proposed. The positioning technique used in this report differs from most of the other techniques in one critical aspect. Our positioning system does not take into account the positions of the...

In future domestic context aware applications the location of mobile devices is often required. Ultrasound technology enables high resolution indoor position measurements. A disadvantage of state-of-the-art ultrasonic systems is that several base stations are required to estimate 3D position. Since fewer base stations would lead to lower cost and easier setup, a novel method is presented that r...

PURPOSE To establish normal exophthalmometry values in the adult Turkish population, and the impact of age, gender, interpupillary distance, Hertel base selection, and refractive status on globe position. METHODS Exophthalmometry measurements and refractive status of 2477 subjects were conducted in one tertiary and five primary health care centers. Change of globe position by age, intersex di...

A position control method for interpolating aspherical grinding and polishing tool path was reviewed and experimented in a nano precision machine. The position-base algorithm was reformed from the time-base algorithm, proposed in the previous study. The characteristics of the algorithm were in the velocity control loop with position feedback. The aspherical surface was divided by an interval at...

Background: Human Adenovirus species D (HAdV-D) was common human viral pathogen especially in eye infection, consists of several types of which HAdV-D8, -D19 and –D37 were common in eye infection. This study includes detection of HAdV-D types implicated in conjunctivitis based on L2 (Penton protein) gene similarity. Methods: Conjunctival swabs were collected from Keratoconjunctivitis patient...

We investigated the processing of violations of the verb position in Dutch, in a group of healthy subjects, by measuring event-related potentials (ERPs) through electroencephalography (EEG). In Dutch, the base position of the verb is clause final, but in matrix clauses, the finite verb is in second position, a construction known as Verb Second. In embedded clauses, the finite verb remains in it...
