Abstract: A short oxygen delignification method employs a mixing assembly including a mixing chamber having an interior wall which is generally symmetrical about a central longitudinal axis. At least one inlet is used to introduce paper pulp, a basic compound, optional steam and an oxygen-containing gas into the mixing chamber. At least one axial baffle is connected to and extends along the interior wall. At least one transverse baffle is connected to and extends from the interior wall transverse to the axis. A rotatable agitator includes at least one agitator baffle extending transverse to the axis at a location in alignment with a respective transverse baffle. This forms at least one gap between the at least one agitator baffle and the at least one respective transverse baffle. The paper pulp fluid is forced to travel through the at least one gap. A short delignification reaction occurs inside the mixing chamber. Delignified paper pulp fluid leaves the mixing chamber through at least one outlet of the mixing chamber.

The retrieved iSCSI data blocks are temporarily stored in the local distributive cache accessing device. If any other diskless computer requests for the iSCSI data blocks, the temporarily stored iSCSI data blocks can be accessible to the diskless computer. Given installation of a large number of diskless computers, the network traffic of the iSCSI target is alleviated, and booting remote diskless computer is accelerated.

Light from the scene is processed through an optical system that comprises a coded-aperture. The optical system projects a plurality of images, each characterized by only one of a plurality of spectral components, onto a photodetector array. The plurality of images is interspersed on the photodetector array, but no photodetector receives light characterized by more than one of the plurality of spectral components. As a result, computation of the spatio-spectral datacube that describes the scene is simplified. The present invention, therefore, enables rapid spectral imaging of the scene.

Abstract: A method for improving data writing speed of a diskless computer is applied to a diskless computer connecting to a remote server that has a disk drive and having a central processing unit (CPU), a host bus adapter (HBA) and a storage unit. The method has acts of retrieving writing data commands by the CPU from an operating system kernel executed by the CPU, writing the requested data to a storage unit in the diskless computer by the CPU, returning a response of finishing writing data to the operating system kernel by the CPU and writing data stored in the storage unit to the disk drive of the remote server by the CPU. Therefore, the operating system kernel receives the response of finishing writing data even though the loading of the network is heavy. Consequently, the speed of the diskless computer writing data increases.
