In this paper, we propose three important enhancements of the approximate cutting plane algorithm (CPA) to train Support Vector Machines with structural kernels: (i) we exploit a compact yet exact representation of cutting plane models using directed acyclic graphs to speed up both training and classification, (ii) we provide a parallel implementation, which makes the training scale almost line...

We present the cases of two children with presumed idiopathic central diabetes insipidus whose follow-up MR studies eventually revealed hypothalamic tumors. Thin-section sagittal T1-weighted MR with gadolinium administration is important in the evaluation of these children, and serial examinations are probably necessary.

In this paper we discuss packet filtering firewalls and an application level gateway approach used to secure handheld devices. We propose a firewall management plane as a means for cross layer interaction. In our approach the application level gateway updates the firewall rules based on its knowledge about whether or not a certain source is sending malicious packets. Hereby we pursue a policy o...

This paper considers the problem of virtualizing the resources of a network processor (NP) in order to allow multiple third-parties to execute their own virtual router software on a single physical router at the same time. Our broad interest is in designing such a router capable of supporting virtual networking. We discuss the issues and challenges involved in this virtualization, and then desc...

The purpose of the study was to evaluate the usefulness of magnetic resonance (MR) in imaging of the cisternal and petroclival segments of the abducent nerve. Heavily T2-weighted submillimetric 3D sequence in axial plane, T1-weighted 3D, 1.5 mm slice thickness sequence in axial plane and TOF sequence were performed on 16 volunteers. Additionally the reformatted T2-weighted images in sagittal an...

The Generalized TTL Security Mechanism (GTSM) describes a generalized use of a packet’s Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to verify that the packet was sourced by a node on a connected link, thereby protecting the router’s IP control plane from CPU utilization-based attacks. This technique improves security and is used by many protocols. This document defines the GTSM use for the La...

We read with interest the work by Saugel et al. [1] about ultrasound-guided central venous catheter placement. In their work the authors accurately describe “in-plane” and “out of plane” techniques for central venous catheter access. However, they describe only briefly the oblique-axis technique and for this approach only articles about internal venous jugular catheterization are cited [2, 3] a...

an important concern in rock mechanics is non-homogeneity as joints or fault. this noticeable feature of failures in rock is appearance of slip surfaces or shear bands, the characteristics of that are associated with deformation being concentrated in a narrow zones and the surrounding material remaining intact. adopting the joints as fractures, fractures are well known for their effects on the ...

sink location is considered as a basic service in geographic routing in wireless sensor networks. obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. in this paper, a sink location algorithm based on fano plane is proposed. the research challenge is how to ensure the intersection of two slq and sla rou...
