Abstract: Systems and methods for managing aftertreatment systems that include passive NOx adsorption devices and SCR catalyst elements are disclosed. Temperature generation devices upstream of the passive NOx adsorption devices facilitate control of the aftertreatment systems to improve fuel economy and NOx conversion efficiency.

Abstract: A system comprises a work load management module and a plurality of datacenter pods communicatively coupled by a network. The data center pods include a first datacenter pod and a second datacenter pod. The second datacenter pod hosts a modified data center application that was migrated from the first datacenter pod in response to a first request. The work load management module receives a second request to revert the modified datacenter application back to the first datacenter pod. The work load management module determines one or more differences between a first pod environment configuration and a second pod environment configuration. The work load management module modifies the modified datacenter application based on the one or more differences to be operable in the first datacenter pod. It then reverts the datacenter application to the first datacenter pod such that the first datacenter pod hosts the datacenter application.

Abstract: According to an aspect of present disclosure, a set of power amplifiers are used to amplify power of a signal for transmission. The signal powers from a set of power amplifiers are coupled to set of primary windings which are commonly coupled to a secondary winding such that the powers on the primary windings are additive in the secondary winding. A current path on the primary side is provided for flow of a current that is induced on at least one primary winding when a power amplifier coupled to that primary winding is in “off” state. As a result, the induced current is prevented from flowing in to the power amplifier that are in “on” state. Further, the current path isolates the power amplifiers from each other thereby enabling the power amplifiers to operate at the rated efficiency. In one embodiment, the current path is provided using a resistor network.

Abstract: According to some embodiments, a system comprises a work load management module and a plurality of datacenter pods communicatively coupled by a network. The data center pods include a first datacenter pod and a second datacenter pod. The work load management module receives a request to migrate a datacenter application from a first datacenter pod to a second datacenter pod. The work load management module retrieves a first pod environment configuration and a second pod environment configuration and automatically determines one or more differences between the first pod environment configuration and the second pod environment configuration. The work load management module modifies the datacenter application based on the one or more differences to be operable in the second datacenter pod and migrates the datacenter application to the second datacenter pod.

Abstract: An area efficient baseband filter is disclosed. In an exemplary embodiment, an apparatus includes a current to voltage (I-V) filter configured to receive an input current signal at an input port and generate a filtered output voltage signal at an output port based on a feedback transconductance. The input current signal comprises an input DC current in addition to a signal current. The apparatus also includes a feedback circuit connected between the output port and the input port, the feedback circuit having at least one transistor configured to couple the input DC current to a signal ground and to provide the feedback transconductance for the I-V filter.
