Current resource provisioning schemes in Internet services leave servers less than 50% utilized almost all the time. At this level of utilization, the servers’ energy efficiency is substantially lower than at peak utilization. A solution to this problem could be dynamically consolidating workloads into fewer servers and turning others off. However, services typically resist doing so, because of...

Ultrasonic pulse-echo C-scan imaging is a widespread method for detecting and characterizing defects in fiber reinforced polymer composites. However, the accurate assessment of complex distributed damage cluster, like barely visible impact damage, multi-layer heterogeneous composites not straightforward. For reliably estimating remaining load carrying capacity and/or useful lifetime damaged com...

On promoting the type IIA side of the N = 1 Heterotic/type IIA dual pairs of [1] to M-theory on a 'barely G 2 Manifold' of [2], by spectrum-matching we show a possible triality between Heterotic on a self-mirror Calabi-Yau, M-theory on the above 'barely G 2-Manifold' constructed from the Calabi-Yau on the type IIA side and F-theory on an elliptically fibered Calabi-Yau 4-fold fibered over a tri...

In this paper the trade restrictiveness of agricultural policies in Iran was measured by the TRIindex for the nine major agricultural products including wheat, rice, barely, maize, soybean,meat (beef meat), soybean oil, sugar and banana over the period 1981 to 2007. The main resultsindicate that there is no trend in above index and high volatility especially in 2006 and 2007years due to conside...

The effect of the weaving architecture and z-binding yarns, for 2D 3D woven composites on low-velocity impact resistance carbon fibre reinforced composites, is investigated benchmarked against noncrimp fabric (NCF). Four architectures, namely: NCF, plain weave (2D-PW), orthogonal: (ORT-PW) twill (ORT-TW), were subjected to 15 J using a 16 mm-diameter, 6.7 kg hemispherical impactor. Nondestructi...
