Heterogeneous communication networks with their variety of application demands, uncertain time-varying traffic load, and mixture of wired and wireless links pose several challenging problem in modeling and control. In this paper we focus on the round-trip time (RTT), which is a particularly important variable for efficient end-to-end congestion control.(More)
Gestational diabetes mellitus (GDM) is increasing in prevalence in tandem with the dramatic increase in the prevalence of overweight and obesity in women of childbearing age. Much controversy surrounds the diagnosis and management of gestational diabetes, emphasizing the importance and relevance of clarity and consensus. If newly proposed criteria are(More)

OBJECTIVE It is uncertain whether the ability to avoid hypoglycaemia during fasting is preserved, and the risk of reactive hypoglycaemia after an oral glucose stimulus following a prolonged fasting period is increased at augmented glucagon-like peptide-1 (GLP-1) levels. DESIGN A randomized, double-blind placebo-controlled cross-over study in eight healthy(More)
— Heterogeneous communication networks with their variety of application demands, uncertain time-varying traffic load, and mixture of wired and wireless links pose several challenging problem in modeling and control. In this paper we focus on the packet delay, which is an important variable for efficient end-to-end congestion control. In particular , we(More)
— The purpose of this paper is to develop a comprehensive framework for modelling and performance analysis of TCP/IP transport protocol across WCDMA wireless interfaces of third and future generations. In this context, we provide a semi-analytical model that captures the behaviours of relevant components of the wireless architecture, such as power control(More)
A fundamental assumption of the tcp protocol is that packet losses indicate congestion on the network. This is a problem when using tcp over wireless links, because a noisy radio transmission may erroneously indicate congestion and thereby reduce the tcp sending rate. Two partial solutions, that improve the quality of the radio link, are power control and(More)
— A new control structure is proposed to improve user experience of wireless Internet. Information on radio bandwidth and queue length available in the radio network controller (RNC), close to the base station, is used in a proxy that resides between the Internet and the cellular system. The control algorithm in the proxy sets the window size according to(More)
