Abstract: A structure includes an item of furniture coupled to a lift system. The lifting system is configured to move the item of furniture vertically along a path between a lowered position and a raised position. The item of furniture is coupled to the lifting system in a manner that allows the item of furniture to move upward along the path when the lifting system is stationary. When the item of furniture is in the lowered position, it is supported on the floor of the structure. This configuration allows the item of furniture to float relative to the lifting system so that when the item of furniture reaches the lowered position, it is supported only by the floor and not the lifting system.

Abstract: Methods, computer program products, and systems are presented. The method, computer program products, and systems can include, for instance: initiating evaluating of a tree data structure expression having nodes and edges between the nodes, wherein a plurality of nodes of the tree data structure expression express functions, and wherein a hierarchy of the tree data structure expression defines an order of execution of functions expressed by nodes of the plurality of nodes; and in response to the initiating, reading, processing and writing tile data of a dataset according to node expressed functions of the tree data structure expression.

Abstract: A bed lift includes a bed support mechanism used to hold a bed in a raised position. The bed support mechanism includes a catch mechanism and a release mechanism. The release mechanism is configured to move the catch mechanism between an engaged position where the catch mechanism holds the bed in the raised position and a disengaged position where the catch mechanism does not hold the bed in the raised position.

Abstract: Automatic threat detection of volumetric computed tomography (CT) data, including: extracting at least one 3-D object from the volumetric CT data; constructing a feature vector for each of the at least one 3-D objects; and classifying each 3-D object as one of a threat or benign object using the feature vector and a set of truth threat and benign objects.

Abstract: A casing string is augmented with one or more variable flow resistance devices or “vibrating tools” to facilitate advancement of the casing and distribution of the cement in the annulus once the casing is properly positioned. The method includes vibrating the casing string while advancing the casing down the wellbore or while the cement is pumped into the annulus, or both. After the cementing operation is completed, the devices may be drilled out to open the casing string for further operations. The casing string assembly may include a vibrating tool at the end in place of a conventional float shoe or float collar. Multiple vibrating tools can be employed in the casing string, and they may be combined with conventional float shoes and collars. Additionally, vibrating tools in the form of plugs can be pumped down and landed inside the casing string.

Abstract: The oxidation of isobutyraldehyde produces isobutyric acid and byproducts, such as isopropyl formate. A process of reducing the isopropyl formate byproduct and other byproducts in the oxidation of isobutyraldehyde is described. The process uses a carbonyl compound, such as acetone, to reduce byproduct levels in the resulting product. Process for use of static mixers in oxidation reactions of aldehydes are also provided.
