Abstract: Techniques are described for performing optimized writes in the volatile memory of DBMS. In an embodiment, DBMS receives, from a client application of a computing device, a request to store a set of data entries for a database object. DBMS identifies at least one buffer in buffer memory in the volatile memory to write first set of data entries. A writer process of the DBMS writes first set of data entries in a buffer of the buffer memory in the volatile memory. Independently of the writer process, based on a buffer mapping data structure for the buffer memory, a flush coordinator process identifies a buffer chain of the buffer chains that includes the written buffer. A background flush process persistently stores first set of data entries from the buffer in the volatile memory to persistent storage of the DBMS.

Abstract: A method aleviating blistering, cracking and chipping in topmost layers of a multilayer system exposed to reactive hydrogen, when producing a reflective optical element (50) having a maximum reflectivity at an operating wavelength of 5 nm to 20 nm. A multilayer system (51) composed of 30-60 stacks (53) is applied to a substrate (52). Each stack has a layer (54) of thickness dMLs composed of a high refractive index material and a layer (55) of thickness dMLa composed of a low refractive index material. The thickness ratio is dMLa/(dMLa+dMLs)=?ML. Two to five further stacks (56) are applied to the multilayer system. at least one further stack having a layer (54) of thickness ds composed of a high refractive index material and a layer (55) of thickness da composed of a low refractive index material, wherein the thickness ratio is da/(da+ds)=? and wherein ???ML.

Abstract: Techniques are provided for granular load and refresh of columnar data. In an embodiment, a particular data object that contains particular data formatted different from column-major format is maintained, the particular data including first data and second data. First and second data objects contain the first and second data, respectively, organized in the column-major format. In response to changes being committed to the first data in the particular data object, invalidating one or more rows of the first data object. In response to a number of invalidated rows of the first data object exceeding a threshold, automatically performing a refresh operation on the first data object independent of any refresh operation on the second data object.

Abstract: Advertising system that adheres printed indicia to surfaces are described. The advertising system can contain a substrate containing the printed indicia layer and an adhesive layer. A protective layer, formed of a substantially clear or transparent material, can be used protect an exterior surface of the substrate. The printed indicia may be coated, screen printed, transfer laminated, etc., to the underlying surface to which the advertising system is attached, as can the protective layer and the adhesive layer when present. The advertising system can be used on non-durable surfaces, as well as surfaces which are exposed to extreme conditions and/or continuous wear have. The advertising system can also be used with moving and non-moving, vertical and horizontal surfaces. The advertising systems also allow application and removal of advertisements quickly and effectively without removing, mechanically altering, or damaging the surfaces to which they are applied. Other embodiments are described.

Abstract: The present invention is directed to conduit or tubing for holding and/or protecting flexible members from exposure and/or contamination. The conduit preferably includes convolute tubing having a longitudinal slit and at least one securing flap for covering the slit to hold flexible members in the internal cavity of the tubing. The use of a flap in the slit conduit substantially prevents flexible members from undesired exit from the cavity of the conduit while at the same time protects the flexible members from exposure to the outside environment and contaminants. A method of manufacturing convolute tubing with a securing flap is also provided.

Abstract: For each metered flow in a network unit there is a memory entry which defines a time stamp and a rate parameter. When a packet in the respective flow arrives, the time of arrival is compared with the time stamp. If the time of arrival is before the time stamp the packet is discarded. If the packet arrives after the date stamp, it is allowed to proceed and a new time stamp is computed in accordance with the rate parameter. One exemplary computation adds to the time stamp a time interval obtained by dividing the size of the packet by the rate parameter and preferably subtracting from the quotient the time interval between the arrival time and the previous time stamp.
