In this paper, we present our work on a level of detail(LoD) technique for human-like face models in virtual environments. Conventional LoD techniques have been adapted to allow facial animation on simplified geometric models. This includes optimization on both geometry, and animation parameters. Simplified models are generated in a region-based manner in consideration with the mobility of each...

PURPOSE To examine the extent of mobility limitations in patients with age-related macular degeneration (AMD), glaucoma, or Fuchs' corneal dystrophy compared with that in a control group of older adults with good vision. METHODS Two hundred seventy-two patients (68 with AMD, 49 with Fuchs' dystrophy, 82 with glaucoma, and 73 controls) from the ophthalmology clinics of Maisonneuve-Rosemont Hos...

AIM Limited joint mobility and plantar pressure in the foot has not been assessed in type 1 diabetes. The aim of this study was to investigate the joint mobility and plantar foot pressure in Asian Indian type 1 diabetic subjects and to see its association with duration of diabetes. MATERIAL AND METHODS The joint mobility and plantar pressure were measured in 115 consecutive subjects attending...

We propose an algorithm that builds and maintains clusters over a network subject to mobility. This algorithm is fully decentralized and makes all the different clusters grow concurrently. The algorithm uses circulating tokens that collect data and move according to a random walk traversal scheme. Their task consists in (i) creating a cluster with the nodes it discovers and (ii) managing the cl...

Mobile ad hoc networks (MANETs) are useful in environment where fixed network infrastructure is unavailable. To function normally, MANETs demand an efficient and distributed medium access control (MAC) protocol. However, characteristics of MANETs such as radio link vulnerability, mobility, limited power pose great challenges on MAC design. This paper surveys the recent advances in MAC design fo...

This paper presents a speech operated smart-home control system with a focus on users with special needs – elderly people, people suffering from blindness or low vision and people with mobility impairments. The proposed system simplifies the use of various home appliances by providing a unified speech-controlled interface and thus improves the quality of their everyday life. The paper presents ...

The performance of services implemented in the serviceoriented knowledge grid becomes one of the most key issues that affect the development of the knowledge grid. This paper presents a knowledge grid architecture based on mobile agent and effectively utilizes mobile agent's mobility, flexibility and intelligence to implement knowledge grid services. The idea that applies MA technologies to the...

Mobility in wireless sensor networks poses unique challenges to the Medium Access Control (MAC) protocol design. Previous MAC protocols for sensor networks assume static sensor nodes and focus on energy-efficiency. In this paper, we present MMAC, a mobility-adaptive, collision-free MAC protocol for mobile sensor networks. MMAC caters for both weak mobility (e.g. topology changes, node joins and...

Base IP mobility presents performance limitations when the mobile host increases its handoff rate between successive wireless points of attachment as a result of its mobility pattern. These limitations are augmented when latency externalities such as the round trip time between the MN and its peers, add to the total of latency and signalling overhead, impeding the performance of the mobility fu...

  Abstract   Background: Osteoarthritis (OA) is the most common joint disease occuring after middle age. Because of the high mobility of the neck, OA is common in the cervical spine. The purpose of this study was to determine and compare the effects of intermittent traction on patients with mild and moderate cervical OA. Therefore, 32 patients with cervical OA were recruited.   Methods: Aclinic...
