Abstract: A method for congestion control in a data communication protocol employing acknowledged communication may include measuring a flight size. A transmission rate may be measured. A trend of the flight size may be determined. A trend of the transmission rate may be determined, and the trend may be derived from a transmission rate gradient calculation, in which either the transmission rate measurements or the transmission rate gradient calculations or both may be filtered to reduce their temporal variability. Whether there is a congestion may be detected according to the determined trend of the transmission rate and the trend of the flight size. Upon detection of the congestion, a change may be made from a current congestion control state to a new congestion control state. Data may be transmitted while respecting a maximum amount of unacknowledged data which the transmitting node may transmit. An apparatus is also disclosed.

Abstract: A method and apparatus for congestion control for acknowledged communication over networks detects congestion based on trends of flight size and transmission rate in order to adapt a congestion window in accordance with a detection result. Such congestion detection enables, for example, distinguishing between the congestion with or without unfair competition. Moreover, the measured transmission rate or its trend can be filtered to compensate for time variations. An end node or a proxy can be used for congestion control.

Abstract: An airbrush apparatus for use in generating a design on a desired object is disclosed. The apparatus and method of use are disclosed wherein the airbrush apparatus comprises a housing, boom, and sprayer head. A fluid to be applied is contained in individual cartridges and is drawn out by a vacuum effect caused by air that is being pumped from the housing across a feed tube which is in fluid communication with the cartridge.

Abstract: There is disclosed the combination of a growth hormone secretagogue and at least one agent which modifies the production or processing of A? in the brain, said at least one agent being selected from: (a) compounds which inhibit the secretion of A?; (b) compounds which selectively inhibit the secretion of the 1-42 isoform of A?; (c) compounds which inhibit the aggregation of A?; and (d) antibodies which selectively bind to A?; for use in treatment or prevention of a disease associated with deposition of A? in the brain.
