An electronic rack includes a housing to contain one or more IT components arranged in a stack, a first rack aisle formed on a first side of the one or more IT components to direct cooler air received from the cooling unit upwardly, and a second rack aisle formed on a second side of the one or more IT components to direct warmer air to the cooling unit downwardly. The electronic rack further includes a cooling unit having one or more cooling units disposed underneath the IT components to receive first liquid from an external chiller system, to exchange heat carried by the warmer air using the first liquid to generate the cooler air, to transform the first liquid into a second liquid with a higher temperature, and to transmit the second liquid carrying the exchanged heat back to the external chiller system.

A data center system includes a container to contain electronic racks of IT components operating therein, a cooling unit disposed underneath the electronic racks to receive cool liquid from a chiller unit, to exchange heat generated from the IT components, and to transmit the hot liquid carrying the exchanged heat back to the chiller unit. Each electronic rack includes a housing to house IT components arranged in a stack, a first rack aisle formed on a first side of the IT components to direct cool air received from the cooling unit upwardly, and a second rack aisle formed on a second side of the IT components to direct hot air to the cooling unit downwardly, where the host air is transformed from the cool air from the first rack aisle by flowing through an air space between the IT components.

One embodiment of the present invention provides a receiver for wireless communication. The receiver includes a group of band-pass filters (BPFs), a wideband amplifier coupled to the BPFs, and a tunable demodulator coupled to the wideband amplifier. A particular BPF is configured to filter RF signals at a particular frequency band. The wideband amplifier is configured to amplify the filtered RF signals. The tunable demodulator is configured to demodulate the amplified RF signals.

One embodiment of the present invention provides a receiver for wireless communication. The receiver includes a demodulator and at least one filtering mechanism coupled to the demodulator, and an analog-to-digital converter (ADC) coupled to the filtering mechanism. The filtering mechanism can be configured to function as a low-pass filter (LPF) or a band-pass filter (BPF), thereby enabling the receiver to function as a direct-conversion receiver or a low-intermediate frequency (low-IF) receiver.

A seller may use an existing product catalog in a seller business information management system to generate an auction and populate auction parameters to expedite and facilitate the auction creation process. The information in the product catalog may be used to provide auction parameters (populate auction fields) in addition to adding a product and/or service to the auction. An auction profile may also be defined for a seller and may contain data or rules for generating an auction that may be used to provide additional default values for the auction. One or more auction profiles may be associated with a seller. The seller selects a product from the catalog and chooses a create auction option resulting in an auction being generated from the product information and the profile, if one exists. The seller may then modify the auction parameters and add or drop products before saving the auction.

An internal auction application may allow a seller to create a multiple auction for a plurality of products and allow a buyer to see and bid on the multiple auction as appropriate. The internal auction application may receive parameters for the multiple auction from the seller and an associated plurality of auctions may be determined for the multiple auction as a function of the parameters. The internal auction application may create and publish the multiple auction and the associated plurality of auctions on a seller's e-commerce site visible to the buyer. The multiple auction may be a serial multiple auction, a recurring multiple auction or a varied sublot multiple auction.

Disclosed is a combination process for improved hydrotreating and catalytic cracking of hydrocarbon oils, including: contacting residual oil, catalytic cracking cycle oil, and optional distillate oil with a hydrotreating catalyst under hydrotreating conditions in the presence of hydrogen followed by separation of the reaction products to obtain gas, hydrogenated naphtha, hydrogenated diesel oil, and hydrogenated tail oil; contacting the hydrogenated tail oil and optional normal catalytic cracking feedstock oil with a cracking catalyst under catalytic cracking conditions followed by separation of the reaction products to obtain dry gas, hydrogenated naphtha, liquefied petroleum gas, catalytic cracked gasoline, catalytic cracked diesel oil, and catalytic cracking cycle oil; wherein the hydrogenated tail oil and/or normal catalytic cracking feedstock oil are separated into at least two fractions, the light and the heavy fractions or normal catalytic cracking heavy feedstock oil and normal catalytic cracking light feedstock oil, prior to contacting the hydrogenated tail oil and/or normal catalytic cracking feedstock oil with the cracking catalyst. The process according to the present invention is especially suitable for conversion of hydrocarbon oils to produce more products of gasoline or diesel oil.
