Activity logs can be used for intrusion detection; however, most previous work on intrusion detection examines only activity logs from a single component. Doing so fails to take advantage of the naturally existing correlations among activities in different types of logs, such as network logs and system call logs. This paper explores correlation for intrusion detection. Specifically, we propose ...

Power-line-communication is to use the mains wiring for data communication. Because mains wiring and plugs are found nearly everywhere in every house, the installation expenses and the costs involved will be reduced, compared to other wire-bound communication solutions. This results in a very attractive alternative for the automation technology, especially for domestic applications. This articl...

  Objective: Corrosion resistance is among the most important properties of metal alloys used in the oral cavity. Consumption of acidic foods reduces the salivary pH and intensifies the corrosion of brackets and orthodontic wires. This study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artifici...

in this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. first, integral equationsgoverning unknown fields on the surface is obtained based on stratton-cho surface integral equations. then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. it is shown that in scatter...

In this study, UAVs were used to collect data of distribution line resources, and defects in equipment construction process identified through deep learning. Different algorithms are identify the process. The research will ultimately support regional synchronization online development for intelligent automatic acceptance wire UAV.

An ultrafine grain surface layer with average crystallite size of 28 nm was produced on annealed mild steel through a wire brushing process. The effects of grain size reduction on the inhibition performance of sodium phosphate were investigated using polarization and electrochemical impedance spectroscopy (EIS) measurements. The crystal grain size of wire brushed surface was analyzed by X-ray d...

Underwater flow sensing is important for many robotics and military applications, including underwater robots and vessels. We report the development of micromachined, distributed flow sensors based on a biological inspiration, the fish lateral line sensors. Design and fabrication processes for realizing individual lateral line sensor nodes are discussed in this paper, along with preliminary cha...

We report an enhanced broadband passive combiner structure using a dense slot-line antenna array in an oversized coaxial waveguide. A significant reduction in size has been achieved while maintaining a 6-18GHz bandwidth and capacity for 32 MMIC amplifiers. A broadband slotline to microstrip line transition is also developed and monolithically integrated with the slot-line antennas, to eliminate...

The quality of grey alder logs (Alnus incana) was studied by sawing sample logs from two different forests in November 1995–February 1996. For grading of grey alder logs and sawn timber the proposed system of Keinänen and Tahvanainen (1995) plus the reject -grade was used. In general, grey alder logs have knots from the base to the top. All types of knots appear, and the length of the knot-free...
