Paper discusses Advanced Aircraft configurational approaches, across the speed range, which are either enabled, or greatly enhanced, by clever Flow Control. Configurations considered include Channel Wings with circulation control for VTOL [but non-hovering] operation with high cruise speed, strut-braced CTOL transports with wing-tip engines and extensive [ÒnaturalÓ] laminar flow control, a midw...

The current WiFi access control framework descends from solutions conceived in the past for dial-up scenarios. A key difference between the two worlds is mobility: dial-up handles nomadic users, while modern wireless networks support continuous mobility through always-on personal devices. Not surprisingly, WiFi authentication does not exploit mobility in any way; on the contrary, mobility is pe...

With the rapid growth of network traffic volumes in terms of the content and mobile data, how to cope with these two new trends of Internet has been widely discussed. Among related solutions, Named Data Networking (NDN) is aimed to achieve highly effective content distribution. Besides, the mobility support is also one of its important research contents, attracting great attentions. Thus, in th...

A hierarchical time division multiple access (HTDMA) medium access control (MAC) protocol is proposed for clustered mobile underwater acoustic networks. HTDMA consists of two TDMA scheduling protocols (i.e., TDMA1 and TDMA2) in order to accommodate mobile underwater nodes (UNs). TDMA1 is executed among surface stations (e.g., buoys) using terrestrial wireless communication in order to share mob...

The research related with digital health records is has been a hot topic since the last two decades, producing diverse results namely two main types – Electronic Health Records and Personal Health Records. Based on those types of records different implementations appeared, although new challenges also emerged. The wider citizen mobility, liberalization of health care providing, alternative medi...

Registration/deregistration with a mobility database called Visitor Location Registers (VLRs) is required in a PCS network when a mobile phone moves between registration areas. Several schemes were proposed to deregister a mobile phone after it moves out of a registration area. A simple scheme, called implicit deregistration, is studied in this paper, which does not specifically deregister any ...

Electric-powered wheelchairs improve the mobility of people with physical disabilities, but the problem to deal with certain architectural barriers has not been resolved satisfactorily. In order to solve this problem, a stair-climbing mobility system (SCMS) was developed. This paper presents a practical dynamic control system that allows the SCMS to exhibit a successful climbing process when fa...

This paper presents preliminary work on the design of control systems for pedestrian mobility aids for the elderly. The elderly are often restricted in their mobility and must rely on canes, walkers and wheelchairs for locomotion. Restrictions in mobility lead to a loss of independence and autonomy, as well as a decrease in muscular strength. This paper focuses on design of intelligent wheeled ...

Multimedia Broadcast/Multicast Service (MBMS) over a Single Frequency Network (MBSFN) within LTE systems is a feature that allows synchronous broadcasting of common data among neighboring cells. With MBSFN operation, mobile broadcast/multicast users are able to use inter-cell interference in a constructive way and to achieve increased bit-rates compared to when conventional broadcasting is used...

Machine perception plays an important role in any intelligent system, and in particular, guiding an autonomous mobile agent. Machine perception techniques have progressed significantly in recent years, however perception systems are still plagued by a lack of flexibility and an inadequacy in performance speed for use in real-time tasks. To overcome these problems, we have applied integrated kar...
