Abstract: An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

Abstract: Techniques for UNDO and REDO operations in a computer-user interface are disclosed. The techniques enables users to configure entities for UNDO and REDO operations. The techniques also enable users to roll back individual entity to an immediate previous state in one UNDO operation and subsequently to the other previous states. Other entities are not affected by the UNDO operations to the entity.

Abstract: Expandable Jacket surrounding a pressuremeter probe prevents barrel shape to form and maintains cylindrical shape with uniform radial displacement throughout its height, removing shortcomings of the existing pressuremeters. For the pressuremeter probe to determine horizontal stress versus plane strain relationship in soils and intermediate geomaterials, an expandable comprises of one layer of circular arch shaped segmented plates surrounded by flexible bands or rings. The expandable jacket surrounds a membrane which itself surrounds a porous tube with holes. Borehole less than the diameter of probe is drilled either by pre-boring or self-boring and then pushing the probe with cutter ring.

The present invention is also directed to novel methods of producing substituted pyrazole based thyroid like compounds, and solid forms of 3-{4-[(7-hydroxy-6-methyl-indan-4-yl)methyl]-3,5-dimethyl-1H-pyrazol-1-yl}-propanoic acid, its pharmaceutical compositions, and methods of preparation thereof.

Abstract: The porous displacement piles comprising (a) closed-ended pipe piles with small holes and or narrow slots, filled with compacted sandy soil, (b) closed-ended porous pipe piles such as closed-ended pipe pile with very small holes and or very narrow slots, and (c) a precast prestressed porous concrete piles are driven through inside the already driven non-displacement hollow pipe piles in a grid pattern to create excess pore-water pressures generally ranging between 50 and 1500 kPa in cohesive soils, which begin dissipating through inside the porous displacement piles to rapidly consolidate and densify the said cohesive soil. The porous displacement piles are designed for permitting free flow of the pressurized pore-water and to prevent migration of particles of cohesive soil into the porous displacement pile using filter design criteria or verified by laboratory tests. These piles when driven in sandy soils densify sandy soils instantaneously.
