The path taken by a packet traveling across the Internet depends on a large number of factors, including routing protocols and per-network routing policies. The impact of these factors on the end-to-end performance experienced by users is poorly understood. In this paper, we conduct a measurement-based study comparing the performance seen using the(More)
Despite its obvious success, robustness, and scalability, the Internet suffers from a number of end-to-end performance and availability problems. In this paper, we attempt to quantify the Internet's inefficiencies and then we argue that Internet behavior can be improved by spreading intelligent routers at key access and interchange points to actively manage(More)
In spite of much research effort, there is no universally applicable software reliability growth model which can be trusted to give accurate predictions of reliability in all circumstances. Worse, we are not even in a position to be able to decide a priori which of the many models is most suitable in a particular context. Our own recent work has tried to(More)

Background/introduction Errors in power output ranging from −100% to +210% have been reported in a multitude of physiotherapy transducers.[1] Differences in power output can arise even after careful calibration on an annual or biannual schedule, which can either result in harm to the patient or non-effective treatment. Therefore, easy implementation of(More)
Temporal lobe epilepsy remains a significant cause of disabling morbidity. Patients that are refractory to medical treatment are often considered for invasive surgery to remove the epileptogenic focus originating from the structures of the medial temporal lobe. A range of surgical options now exist with varying degrees of efficacy. The goal of any surgical(More)
Thermal therapy is currently limited to central areas of the brain in order to maximize the antenna gain between the outer cortex and the target. So far, clinical applications have been limited to thalamotomies for neuropathic pain, essential tremor and Parkinsonian tremor. We developed numerical simulations and head phantoms in order to investigate the(More)
The biologic dose response curves of thermal dose and absorbed radiation dose have not been compared to each other even though they have both been extensively investigated separately and combined. Although heat and radiation produce cell kill by different biological mechanisms (Thermal dose denatures proteins and the radiation dose causes DNA damage) a(More)
In vivo low frequency MR-guided thalamotomy with focused ultrasound: thermal vs mechanical lesioning in pig brain The purpose of this study was to investigate the thresholds for inducing two possible means of tissue destruction with low frequency Magnetic Resonance guided Focused Ultrasound (MRgFUS): either mechanical lesioning in presence of ultrasonic(More)
Precise focusing is essential for transcranial MRI-guided focused ultrasound (TcMRgFUS) to minimize collateral damage to non-diseased tissues and to achieve temperatures capable of inducing coagulative necrosis at acceptable power deposition levels. CT is usually used for this refocusing but requires a separate study (CT) ahead of the TcMRgFUS procedure.(More)
