investigation on thermal properties of epoxy composites filled with pine app...Ijripublishers Ijri
he present paper deals with the effect of volume fraction of fillers on the thermal Properties of polymer composites. This work sees an opportunity of enhancement on insulation capability of a typical fiber reinforced polymer composite. To validate this mathematical model, a set of epoxy based composites, with fiber content ranging 4.38 to 20.10% of volume fractions have been prepared by simple hand lay-up technique. For preparing the composite, natural fiber i.e. Pine apple leaf fibers are incorporated in Epoxy Resin. Thermal conductivities of these composite samples are measured as per ASTM standard E-1530 by using the Unitherm™ Model 2022 tester, which operates on the double guarded heat flow principle at the temperature ranging from 30˚C to 150˚C. And also the Specific Heat of the powdered samples are measured by using Differential Scanning Calorimeter (DSC). By using the MATLAB the numerical analysis is carried out to find the value of Thermal Diffusivity with varying temperatures. It was observed that the thermal diffusivity varies with fiber concentration, but the variation of thermal diffusivity with varying temperature was not so significant.
KEYWORDS: Pine Apple Leaf fiber, Epoxy Composites, Volume Fraction, Thermal Properties.
The cyber house of horrors - securing the expanding attack surfaceJason Bloomberg
The enterprise attack surface has exploded in recent years. More users on more devices in more locations are able to access ever more sensitive enterprise applications. The result is that the number of targets for attackers has gone up dramatically.
The expanding attack surface has been dubbed a “Cyber House of Horrors,” as insider risks, aggressive social engineering, exploitation of outdated access controls, and a range of other security issues have come to the fore.

What factors are driving the expansion of the attack surface?
What types of attacks and exploits are taking advantage of these changes?
How are segmentation techniques and access controls evolving in response?
