This paper describes an approach to detecting distributed denial of service (DDoS) attacks that is based on fundamentals of information theory, specifically Kolmogorov complexity. The algorithm is based on a concept of Kolmogorov complexity that states that the joint complexity measure of random strings is lower than the sum of the complexities of the(More)
Active network technology envisions deployment of virtual execution environments within network elements, such as switches and routers. As a result, inhomogeneous processing can be applied to network traffic. To use such technology safely and efficiently, individual nodes must provide mechanisms to enforce resource limits. This implies that each node must(More)
— This study is the first known implementation of jitter control in an active network. Jitter control is performed by active packets in a distributed packet by packet basis within an active network rather than on a per flow basis as in today's passive networks. This provides many new benefits and challenges. The concept and results of an experimental(More)
Severe pulmonary hypertension in a teenager with end-stage renal disease on chronic hemodialysis via arteriovenous access is reported. Clinical presentation included persistent volume overload and pericardial effusion. Serial hemodynamic data obtained at cardiac catheterization confirmed the diagnosis. In addition, detailed biochemical and imaging data(More)
The prevalence of non-communicable diseases like diabetes mellitus (DM) and hypertension (HTN) is growing worldwide. Both lead to nephropathy if not controlled effectively. Microalbuminuria (MAU) is recognized as an early predictor for nephropathy. Additionally, the timely detection of advanced glycation end products (AGEs) is also considered to be an(More)
