During the Emilia-Romagna earthquake (2012), a great number of steel racks used to store cheese wheels collapsed, causing non-negligible damage Italian economy. Therefore, for similar structures that survived and are in service, deep investigation towards assessment their effective safety is required. In seismic analysis these frames, mechanical constraint acting onto due reinforced concrete si...

This paper presents a state-of-the-art review on seismic tests of adjustable pallet rack systems: particular components racks, subassemblies, full racks and stored goods. The tested are the most critical connections: beams-to-uprights, braces-to-uprights, floor-to-uprights; subassemblies also include beam-to-upright connections, among other components. Tests can be static (pushover), pseudo-dyn...

A porphyrin appended norbornenyl building block 8 has been isolated and coupled, using a 1,3-dipolar ACE reaction, to yield bis-porphyrin compounds in which the porphyrin moietes are angled upward relative to the norbornane backbone.

Bring home now the book enPDFd from diagnosis to treatment an approach to treatment planning for the emotionally disturbed child to be your sources when going to read. It can be your new collection to not only display in your racks but also be the one that can help you fining the best sources. As in common, book is the window to get in the world and you can open the world easily. These wise wor...

Awaiting uncertain news is stressful, but is it more stressful than receiving bad news? We compared these emotional experiences in two studies. Participants in Study 1 reflected on a personal experience awaiting news that ultimately turned out badly, and participants in Study 2 were law graduates awaiting their results on the bar exam who ultimately failed the exam. In Study 1, participants wer...

Cloud interactive data-driven applications generate swarms of small TCP flows that compete for the switch buffer space in data-center. Such require a flow completion time (FCT) to be effective. Unfortunately, is myopic with respect composite nature application data. In addition it tends artificially inflate FCT individual by several orders magnitude, because its Internet-centric design, fixes r...

Steel storage racks are widely used in logistics for storing materials and goods. Rack design is carried out by adopting the so-called design-assisted-by-testing procedure. In particular, experimental analyses must be rack producers on key structural components order to adopt approach proposed more traditional carpentry frames. For existing racks, i.e., those in-service decades, it required eva...

In the datacenter rented to Internet Service Providers (ISPs), the low utilization of racks can seriously affect ISPs’ benefit because the ISPs are charged by “rack per year” rather than servers. Based on our analysis about the utilization data from production systems, we find that the over-provisioning of power results in low power utilization, which potentially decreases rack utilization as w...
