In this paper we describe a method for near real-time identification of attack behavior and local security policy violations taking place over SSH. A rational is provided for the placement of instrumentation points within SSHD based on the analysis of data flow within the OpenSSH application as well as our overall architectural design and design principles. Sample attack and performance analysi...

Many tools for analyzing distributed systems propagate contexts along the execution paths of requests, tasks, and jobs, in order to correlate events across process, component and machine boundaries. _ere is awide range of existing and proposed uses for these tools, which we call cross-cutting tools, such as tracing, debugging, taint propagation, provenance, auditing, and resourcemanagement, but...

Run-time trace data helps to debug and analyze the parallel programs. Obtaining and managing this data during run-time is the responsibility of an instrumentation system that incurs overhead. In its worst case, this overhead can result in severe perturbation of the behavior of the actual program. This paper presents a queuing model for an instrumentation system. The purpose is to provide a rigo...

AIM To evaluate the number of bacteria extruded apically from extracted teeth ex vivo after canal instrumentation using the two engine-driven techniques utilizing nickel-titanium instruments (ProTaper and System GT). METHODOLOGY Forty extracted single-rooted human mandibular premolar teeth were used. Access cavities were prepared and root canals were then contaminated with a suspension of Ent...

An outline of the basic steps involved in the production of voluntary movement is quite simple. Commands initiated in the brain are transmitted along nerves to muscles. When activated by nerves, muscles generate forces. Muscle forces are transferred to bones and produce angular motions of the joints. When the nervous system properly coordinates the activation of many muscles, the result is smoo...

Online interaction with computer systems and applications allows developers to monitor, experiment with, and debug long-running, resource-intensive applications at runtime. Traditionally, developers statically bind a monitoring mechanism to each application-specific instrumentation point. This approach has shortcomings for online, interactive monitoring. Namely, static binding limits portabilit...

The need for simulation of human foot mechanism has made researchers and engineers move towards different patterns to describe this movement. In this regard, optimal solutions such as energy consumption, accuracy, etc. are of utmost importance. In this paper, efforts have been made to present a new solution by designing a fully two-dimensional six-bar mechanism with one degree of freedom so tha...

The purpose of this research is to enhance the methods used in biomechanical rehabilitation by combining virtual reality, artificial intelligence, motion capture and biofeedback instrumentation. During training, the subject wears 3D glasses, in which virtual tasks (i.e. trajectories) are displayed to him. The subject is then asked to follow the virtual task displayed to him and match his own mo...
