20140372356 | PREDICTIVE PRE-LAUNCH FOR APPLICATIONS - Systems and methods of pre-launching applications in a computer system, said applications being likely to be activated by a user from a terminated and/or suspended process state, are disclosed. The pre-launching of an application may be based on the assessed probability of the application being activated—as well as the level of availability of system resources to affect such pre-launching. Applications may be pre-launched based on these and other conditions/considerations, designed to improve the user's experience of a quick launch of applications in the background. Several prediction models are presented to provide a good estimate of the likelihood of an application being activated by a user. Such prediction models may comprise an adaptive predictor (based on past application usage situations) and/or a switch rate predictor (based on historic data of an application being switched and, possibly, having a decay rate applied to such switch rate measure). | 12-18-2014 |

20160110283 | ON-DEMAND EXPANSION OF SYNCHRONIZATION PRIMITIVES - Disclosed are techniques and systems for providing on-demand expansion of a non-cache-aware synchronization primitive to a cache-aware form. The expansion may occur on-demand when it becomes necessary to do so for performance and throughput purposes. Expansion of the synchronization primitive may be based at least in part on a level of cache-line contention resulting from operations on the non-cache-aware synchronization primitive. The synchronization primitive in the expanded (cache-aware) form may be represented by a data structure that allocates individual cache lines to respective processors of a multiprocessor system in which the synchronization primitive is implemented. Once expanded, the cache-aware synchronization primitive may be contracted to its non-cache-aware form. | 04-21-2016 |

20140371334 | SLURRY PHASE APPARATUS - A method of operating a slurry phase apparatus includes feeding one or more gaseous reactants into a slurry body of solid particulate material suspended in a suspension liquid contained inside a vessel. The one or more gaseous reactants are fed into the slurry body through a gas distributor having downward facing gas outlets and are fed towards a fluid impermeable partition spanning across the vessel below the gas distributor. The partition divides the vessel into a slurry volume above the partition and a bottom volume below the partition. A differential pressure is maintained over the partition between predefined limits by manipulating or allowing changes in the pressure in the bottom volume by employing a pressure transfer passage establishing flow or pressure communication between the bottom volume and a head space above the slurry body. | 12-18-2014 |

20120262024 | Squirrel-Cage Rotor And Method For Producing Such A Squirrel-Cage Rotor - Squirrel cage rotor and method for the production thereof including a rotor shaft having a solid rotor portion formed of ferromagnetic material having a plurality of through-passages extending in an axial direction of the rotor shaft, a plurality of electrically conducting bar elements each received in a through-passage so that the respective bar elements extend in the axial direction. The bar elements each have a first longitudinal end and a second longitudinal end, and two electrically conducting end elements which electrically connect the longitudinal ends to form a squirrel cage is formed by the bar elements and end elements. The bar elements are received in the through-passages in such that relative movement in the axial direction between the solid rotor portion and the bar elements is enabled when there is a change in length of the bar elements and/or of the solid rotor portion. | 10-18-2012 |
20130033148 | ELECTRIC MACHINE - An electric machine has a housing with an inner circumference; a stator which is inserted into the housing so that an outer circumference of the stator is located opposite the inner circumference of the housing, a clearance fit being formed between the inner circumference of the housing and the outer circumference of the stator; at least one fastening element, each fastening element connects the stator to the housing by positive engagement so that the stator is held at the housing so as to be fixed with respect to rotation relative to it; and a rotor which is rotatably mounted in the housing in a radial direction of the electric machine inwardly of the stator. | 02-07-2013 |
20130195618 | Underwater Compressor Arrangement And Underwater Process Fluid Conveying Arrangement Equipped Therewith - Underwater compressor arrangement and underwater process fluid conveying arrangement outfitted therewith. The underwater compressor arrangement has a housing, a turbocompressor with a compressor rotor, and a rotary drive unit with a drive rotor. The turbocompressor and rotary drive unit are arranged in the housing, and the compressor rotor is in rotationally driving connection with the drive rotor. The housing is hermetically sealed with the exception of operating connections for the turbocompressor and rotary drive unit, The compressor rotor is rotatably supported in the housing by a rolling element bearing arrangement. | 08-01-2013 |
20150086329 | MULTI-STAGE RADIAL COMPRESSOR UNIT COMPRISING GAS REMOVAL DURING A COMPRESSOR STAGE - A radial compressor unit for compressing gas has several compressor stages. Each compressor stage includes an impeller having rotor blades, and a flow channel arranged downstream of the impeller, as viewed in the flow direction of the gas to be compressed, having a diffusor section, a deflection section, and a recirculation section having guide blades. The gas compressed in a compressor stage can be removed as cooling gas for cooling a component to be cooled, and can be conveyed in the direction of the component to be cooled. The cooling gas can be removed adjacent to an intermediate wall of the compressor stage from the deflection section and/or the recirculation section of the flow channel of the compressor stage. | 03-26-2015 |
20150145362 | END PLATE FOR AN ELECTRIC MACHINE, ELECTRIC MACHINE AND METHOD FOR ASSEMBLING AN ELECTRIC MACHINE - An end plate for an electric machine includes: a bearing receptacle in which a magnetic bearing which is configured for rotatably mounting a rotor of the electric machine can be accommodated; and a radially outwardly pointing circumferential contour on which a number of at least three supporting elements are provided, which supporting elements each protrude radially beyond the circumferential contour by a determined protruding amount, with the result that the supporting elements define a discontinuous external circumferential contour of the end plate. The respective protruding amounts of the support elements are dimensioned such that the end plate can be fitted in by making a center of the magnetic bearing correspond to at least one of a geometric longitudinal axis of the electric machine and a magnetic longitudinal axis of the electric machine. | 05-28-2015 |

20150212898 | DATA MIGRATION METHOD AND SYSTEMS - The invention relates to a method and system for migrating data stored in a second computing system to a first computing system, particularly wherein the first computing system is a local file system and the second computing system is a backup file system storing files to be transferred to the local file system. The method comprises pre-allocating a primary file matching a corresponding secondary file the second computing system. In response to receiving a read request for a data block not yet stored in the primary file, method comprises retrieving the requested data block from the secondary file and storing same locally in the primary file such that it is usable in the local system. The primary file is automatically populated with data blocks from the secondary file until it is complete in respect of data blocks stored. The system substantially carries out the method of the invention. | 07-30-2015 |
