control radio scheduler queues in Node B. In this paper we propose an algorithm that also provides congestion control in the transport network. The performance analysis concentrates on transport network limited scenarios and shows that the algorithm can achieve high end-user perceived throughput, while maintaining low delay and loss in the transport(More)
The purposes of this study were to determine the prevalence of concha bullosa in patients with chronic sinusitis, to assess the origin of the pneumatisation (from the anterior or posterior ethmoid cells), and to evaluate the significance of the concha bullosa in the genesis of inflammatory sinus disease. We reviewed the CT studies of 308 patients with(More)
To compare various obstetrical methods with different types of obstetrical fractures, 29 neonates with fractures were evaluated retrospectively. Plain films of skull, limbs and chest were obtained. Transfontanellar ultrasonography was performed in one case and a computed tomographic scan of the skull in two. We reviewed 12 fractures of long bones, 7(More)
In this paper we propose a Connection Admission Control (CAC) algorithm to provide Quality of Service (QoS) in UMTS Terrestrial Radio Access Networks (UTRAN). In UTRAN, the main QoS requirement is to ensure low packet delays. The CAC algorithm works with priority scheduling , which is used for QoS differentiation. We give a detailed investigation on the(More)
The purpose of this study was to determine the risk factors predisposing to an obstetric fracture, and their long-term outcome. We reviewed 28 obstetric fractures treated in the County of Vaud, Switzerland, between 1976 and 1989. There were 12 fractures of long bones, 10 clavicles and 6 depressed skull fractures. The belief that obstetric fractures occur in(More)
This is a position paper regarding the role of middleboxes and mid-dlebox layer in an evolved protocol stack. The focus of the paper is on the requirement of cellular networks, but the statements are not limited to cellular systems. The paper describes relevant properties of cellular networks and discusses the related roles of the middleboxes. It addresses(More)
