Most interaction with computers today takes place in a two dimensional environment. Even when using three dimensional graphics applications, input is often still restricted to two dimensions. Many believe that the use of three dimensional input devices will alleviate this restriction and allow for a much more natural human-machine dialog. This thesis seeks to establish how factors dealing with ...

The primary objective of the Orbital Recovery System (ORS) is to provide low-cost lifetime extension for nearly fueldepleted operational geostationary telecommunication satellites. The concept is to have the ORS approach the client satellite in GEO, dock with it and provide attitude and orbit control services over a period of several year. The development of ORS is carried out as a public-priva...

We present a new map showing dimeric kinesin bound to microtubules in the presence of ADP that was obtained by electron cryomicroscopy and image reconstruction. The directly bound monomer (first head) shows a different conformation from one in the more tightly bound empty state. This change in the first head is amplified as a movement of the second (tethered) head, which tilts upward. The atomi...

appendiceal orifice by endoscopic submucosal dissection Adenomatous polyps of the appendix are rare [1,2]; in some cases polypectomy is unsuccessful and surgical treatment is required [3]. Appendiceal polypectomy at colonoscopy is carried out extremely rarely [4]. This is the first reported case of an adenoma of the appendix resected using a traction device during endoscopy. A 63-year-old man a...

The following paper introduces the work conducted to create a relative virtual mouse based on the interpretation of head movements and face gesture through a low cost camera and the optical flow of the images. This virtual device is designed specifically as an alternative noncontact pointer for people with mobility impairments in the upper extremities and reduced head control. The proposed virt...

The head-up-tilt-test in pediatric patients for the evaluation of syncope shows a sensitivity of 35-85% and often requires pharmacological stimulation in order to improve its diagnostic value. We used a new device for beat-to-beat blood pressure monitoring combined with impedance cardiography in a 12-year-old girl during tilt testing. A seven seconds asystolia was provoked. The haemodynamic par...

Successful protein-ligand docking depends upon two factors: exhaustive exploration of search space and effective scoring. In this case study we explore the improvements that can be gained in both pose prediction and scoring by applying two different algorithms to explore conformational space of flexible rings. The first algorithm, ring corner flipping 2 has been part of GOLD since its inception...

mA. The device was deposited onto a polished glass substrate and sandwiched with a second polished piece of glass for prot~ection. At the peak in wavelength response (2 mils), an rnls output of about 25 mV was achieved. The response vanished into widebmd tape noise for a wavelength below 50 pin. A maximum rms signal-to-rms tape noise of about 66 dB wa.s observed. An applied bias field of about ...

Orpheus mobile robot is a teleoperated device primarily designed for remote exploration of hazardous places and rescue missions. The robot is able to operate both indoors and outdoors, is made to be durable and reliable. The device is controlled through advanced user interface with joystick and head mounted display with inertial head movement sensor. To increase the system’s operability in diff...

Trajectory information can be analysed in both the time and space dimensions via a new metric called the M-metric. The M-metric is a measurement definition which quantifies the allocation of control across multiple degrees of freedom. Allocation of control is defined as the product of two components, the simultaneity of control and the efficiency of control, corresponding to the time and space ...
