Letter to the Editor - Congenital Heart Disease with Rheumatic Fever and Rheumatic Heart Disease: A Coincidence or an Association?

The incidence of congenital heart disease (CHD) is about 8 per 1000 live births.1 The prevalence of rheumatic heart disease (RHD) in school-aged children is estimated to be in the range of 2-11 per 1000.2,3 Hence, the occurrence of both these conditions in the same patient can be considered to be uncommon. We carried out a retrospective study in a tertiary referral centre with an aim to analyse the co-existence of CHD and Rheumatic fever (RF)/ RHD

VR-based wheeled mobile robot in application of remote real-time assembly

The objective of this paper is to develop an appropriate methodology with open architecture for real-time monitoring and remote control of networked mobile robot. An integrated product data model and the related configuration management methods are generated. Within the context, this paper presents a new enabling technology to bring traditional robotic tools on-line with combined monitoring and control capability. Under a hybrid architecture of Web browser/server and client/server, an application system is presented to manipulate the wheeled mobile robot data and to carry out a variety of assembly functions. Issues such as architecture design, methodology development, and prototype implementation are addressed through a component assembly case study. Finally, a CORBA stands-based integration framework is proposed to achieve interoperability among multiple data and application objects over the Internet
