In the presence of satellite channels, one of the most challenging problems for TCP is to achieve fair bandwidth sharing among several competing connections with round-trip propagation delays that may differ by more than two orders of magnitude. The Bandwidth Aware TCP (BA-TCP) provides a fair solution while maintaining the end-to-end semantics of transport(More)
Effects of ocean–atmosphere feedback processes and large-scale atmospheric stochastic forcing on the interdecadal climate variability in the North Atlantic and North Pacific Oceans are examined in a simple midlatitude ocean–atmosphere model. In the ocean, the authors consider a linearized perturbation system with quasigeostrophic shallow-water ocean(More)
This paper proposes a feedback-based algorithm for congestion control and bandwidth allocation in the presence of either TCP traffic or both TCP and real-time traffic. In this proposal, the network layer conveys bandwidth and propagation delay measurements to data sources, for instance using IPv6 optional fields. TCP sources use this bandwidthdelay product(More)
Congestion in the Internet is becoming a major cause of network performance degradation. The Generalized Window Advertising (GWA) scheme proposed in this paper is a new approach for enhancing the congestion control properties of TCP. GWA requires only minor modiications to the existing protocol stack and is completely backward compatible, allowing GWA-hosts(More)
A simple midlatitude coupled model for idealized ocean basins is used to investigate processes of ocean– atmosphere interaction and its role in interdecadal climate variability at midlatitudes. The ocean model consists of a linearized quasigeostrophic upper ocean layer and a sea surface temperature (SST) equation for an embedded surface mixed layer. The(More)
The morphology and position of pelvis are critical in regulating the biomechanical organization of spine–pelvis–leg in the sagittal plane. Several radiological parameters have been developed to present the sagittal morphology of the pelvis such as pelvic incidence (PI) and Jackson’s angle (PRS1). In addition, the femoral sacral posterior angle (FSPA) was(More)
Treatment of high congenital dislocation of the hip (CDH) remains controversial. We report the outcome of hip arthroplasty using a cementless threaded cup and a cementless straight stem in patients with high congenital hip dislocation. Between January 2001 and August 2004, 17 patients with high congenital hip dislocation were treated. During surgery, at(More)
Deep vein thrombosis (DVT) remains a life-threatening complication of arthroplasty, despite the development of preventive measures. DVT is caused by both acquired and genetic risk factors. The identification of persons at high risk of DVT clearly aids prevention of the same. Age, sex, pregnancy, hormone therapy, an increase in body-mass index (BMI), history(More)
Sagittal spinopelvic malalignment has been reported in spinal disorders such as low back pain (LBP), and restoration of normal alignment is targeted when treating these disorders. Abnormal sagittal spinal–pelvic–leg alignment has been reported in patients with severe hip osteoarthritis (OA), who have a high prevalence of associated LBP. This prospective(More)
