The projector unit on the robot’s back (Figure 1) projects text, graphics and video information towards a wall next to the user. With video phone communication a camera in the robot’s head is used to transmit the user’s video stream towards the communication partner (Figure 2). This is intended for social communication (friends, family members), video communication to medical services and in th...

Background and Purpose: Low back pain (LBP) is a world health problem and a major cause of disability. Also, LBP is a major occupational problem among nursing staff. The study is to determine low back pain, disability, quality of life (QOL) and the associations between LBP with job-related risk factors and dimensions of QOL in nurses. Materials and Methods:  In this study cross-sectional descr...

This paper presents the design and implementation of a communication protocol for the IBM Cyclops-64 (C64) supercomputer system to enable reliable data transfer between the two major components of a C64 system: the C64 host system (also called C64 frontend) and the C64 compute engine (also called C64 back-end). The building block of C64 compute engine (C64 chip) employs a multi-core-on-a-chip a...

Any factorization/back substitution scheme for the solution of linear systems consists of two phases which are different in nature, and hence may be inefficient for parallel implementation on a single computational network. The Gauss-Jordan elimination scheme unifies the nature of the two phases of the solution process and thus seems to be more suitable for parallel architectures, especially if...

Multicast content delivery can be expected to become a major source of revenue with the increase of private broadband fixed and mobile communications. Several multicast applications require the receivers to securely send some real-time information back to the source, which leads to a many-to-one communication scenario. Using unicast connections to send this reverse traffic results in a data imp...

We propose a 2D display and camera arrangement for video communication systems that supports both spatial information between distant sites and user mobility. The implementation of this arrangement is called the “surrounding back screen method.” The method enables users to freely come from and go into other users’ spaces and provides every user with the direct pointing capability, since there i...

BACKGROUND The prevalence of chronic diseases such as type 2 diabetes and chronic low back pain is rising. Patient empowerment is a key strategy in the management of chronic diseases. Patient empowerment can be fostered by Web-based interactive health communication applications (IHCAs) that combine health information with decision support, social support, and/or behavioral change support. Tailo...

Wireless sensor networks (WSNs) have been extensively applied in many domains such as smart homes and Internet of Things (IoT). As part of WSNs’ communication protocols, back-off mechanisms play an essential role in the deployment of wireless channels for network nodes and have been at the core of ensuring effective communication. The performance of many back-off algorithms is excellent in ligh...
