A Stochastic Channel Model With Dual Mobility for 5G Massive Networks

IEEE Access, 2019
In this paper, a new stochastic channel model (SCM) is proposed for fifth-generation (5G) systems. By means of the sum-of-sinusoids (SoS) method to generate spatially consistent random variables (SCRVs), the proposed model extends the 3rd Generation ...

Differential dual‐hop relaying under user mobility [PDF]

IET Communications, 2014
This study studies dual‐hop amplify‐and‐forward relaying system employing differential encoding and decoding over time‐varying Rayleigh‐fading channels. First, the convectional ‘two‐symbol’ differential detection (CDD) is theoretically analysed in terms of the bit error rate.

Versatile IPv6 mobility deployment with dual stack mobile IPv6 [PDF]

Proceedings of the 3rd international workshop on Mobility in the evolving internet architecture, 2008
In this paper, we show how Mobile IPv6 support for dual stack Hosts and Routers (DSMIPv6) can be used as a very efficient, automatic and autonomous way of network planning as well as a multipurpose mobility solution. Along with the details of the Linux-based implementation, we show the results of measurements made against a test scenario that heavily ...

Effect of Dual Task Training on Balance and Functional Mobility in Children with Cerebral Palsy

Reabilitacijos Mokslai: Slauga, Kineziterapija, Ergoterapija, 2020
Research background. It was found that dual task training improves functional abilities in subjects with neurological disorders, however it is not known how dual task training affects balance and functional mobility in children with cerebral palsy (CP).

Hip stability parameters with dual mobility, modular dual mobility and fixed bearing in total hip arthroplasty: an analytical evaluation

BMC Musculoskeletal Disorders, 2022
Background Use of dual mobility (DM) in total hip arthroplasty has gained popularity due to the ability to reduce dislocation through increased jumping distance and impingement-free arc of movement.

Using the cell phone while standing or walking affects balance and mobility in people with Parkinson's disease

Arquivos de Neuro-Psiquiatria, 2023
Background Cell phones are part of peoples' lives. The literature indicates risks when cell phones are used during a secondary motor task. Studies addressing this topic in people with Parkinson's disease are still scarce.

CONSTRAINED LINERS AND DUAL MOBILITY SYSTEMS FOR PREVENTION OF INSTABILITY IN REVISION HIP ARTHROPLASTY

Travmatologiâ i Ortopediâ Rossii, 2018
Purpose. Instability is a challenging complication of revision hip arthroplasty and a frequent cause of repeat revisions. Constrained liners and dual mobility systems have gained major attention among the options of dislocation prophylaxis.

Use of a modular hip dual-mobility articulation in patients with high risk of dislocation: a relatively small-sized acetabulum in Asian patients may limit its use

Arthroplasty, 2021
Background Dual-mobility hip component is widely used in Europe and North America, because it effectively reduces hip dislocation in primary and revision total hip arthroplasties.

Cementation of a Metal Dual Mobility Liner in Patients Undergoing Revision Total Hip Arthroplasty

Arthroplasty Today, 2023
Background: Dual mobility liners for primary and revision total hip arthroplasties can lead to decreased dislocation and revision rates. However, there are a lack of data analyzing their utilization when cementing into well-fixed acetabular components in
