Adjustable suture in strabismus surgery is a way to get accurate alignment of the eyes after operation. This technique is used in cooperative patients, being either adults or children. We report the result of this technique in 120 patients, 70 with esotropia and 50 exotropia. The amount of deviation was between 20 and 60 prismdiopters. The patients were mostly adults and teenagers. and the...

This paper presents a virtual manipulation environment dealing with elastic objects. An original fast computation elastic model ‘the gradational resolution model’ is introduced for real-time interaction, in which the number of elastic elements are efficiently reduced for acceleration. Joystick force feedback is used for sensible interaction. Two kinds of collision algorithms are examined by joy...

This work presents force control in dual arm planar cooperative space robot for cooperative manipulation by two arms. A docking operation by the two arms of the space manipulator has been carried out. During docking operation, space robot requires mechanical interaction with compliant objects, which encounter force and motion constraints. The gripping force should be such that the object should...

Operation transformation has been recognized as a promising approach to intention preservation and consistency maintenance in cooperative editing systems. To deal with the complications caused by the fact that independent operations may come from diierent document states, we propose a pair of mutually reversible inclusion and exclusion transformation functions, which can be used to eeectively i...

Cooperative vehicular communication systems are being developed to improve traffic safety and efficiency through the wireless exchange of information between vehicles and between vehicles and infrastructure units. The future deployment of cooperative active safety applications requires their prior extensive testing due to their critical nature and strict quality of service requirements. Such te...

Title of dissertation: MEDIUM ACCESS CONTROL AND NETWORK CODING FOR WIRELESS INFORMATION FLOWS Yalin Evren Sagduyu, Doctor of Philosophy, 2007 Dissertation directed by: Professor Anthony Ephremides Department of Electrical and Computer Engineering This dissertation addresses the intertwined problems of medium access control (MAC) and network coding in ad hoc wireless networks. The emerging wire...

In this paper, a new scheme of combining cooperative diversity with network coding is proposed for wireless uplink multi-source multi-relay networks. The existing network-coded cooperative scheme always conducts network coding operation at relays in moderate-to-high signal-to-noise ratio region. Distinct from it, the proposed scheme determines either a direct cooperative mode or a network-coded...

III Lincoln Laboratory recently completed the three-year Short-Wavelength Adaptive Techniques (SWAT) field program, designed to investigate the performance of adaptive optics in a variety of scenarios. This article describes the operation of the SWAT adaptive optics system working with cooperative beacons. Examples are presented of system operation in compensating star images and in propagating...

Cooperative applications need proper transactional support for coordinating joint activities, sharing of data, and semantically correct exchange of information of collaborating users. Conventional transaction models based on the ACID properties do not meet the typical requirements of cooperative applications. The CoAct model [27] is designed for supporting cooperative work in multi-user environ...
