Abstract: In some examples, a method for estimating the cetane number of a fuel includes receiving current engine operating condition measurements from a compression ignition (CI) engine using the fuel, and determining a value for a current engine performance indicator. The method further includes determining a projected engine performance indicator value for the CI engine based on the current estimated cetane number, current engine control signals and the current engine operating condition measurements. The method also includes determining that a difference between the value of the current engine performance indicator and the projected engine performance indicator value is greater than a threshold amount. If the difference is greater than the threshold amount, the method also includes determining a new estimated cetane number.

Abstract: A system and method provides a broadband network node for a best effort network such as the Internet or intranets which supports the inexpensive and rapid deployment of services to the best efforts network. Separate data path and control path mechanisms allow high-speed data transfers with parallel processing flows for the data path that are controlled across data flows by the control path. Packets are classified, modified and shaped to enable the service on the network with an accountant to track packet traffic for control and billing purposes. A series of processing blades perform a modification function for each blade that processes packets according to classifications. The processing blades are modular and scalable for insertion in the broad band switch to rapidly adapt the broadband network node for new services.

Abstract: A compound of the formula I where R represents unsubstituted or substituted, alkyl, cycloalkyl, alkenyl, alkynyl, or aryl, and X represents where R1 and R2 are each H or alkyl, is disclosed. Compounds of formula I are particularly useful as an attractant for cockroaches, namely, Blattella germanica. Synthesis of the compounds, methods of controlling cockroach populations, and of disrupting cockroach mating are also disclosed.

Abstract: A method of processing oat groats for imparting shelf stability to the groats by inactivating the enzymes of the groat without causing oxidation. By the subject invention the enzymes of the dehulled oats are deactivated by steaming, boiling or toasting. The boiled and steamed groats are then dried at a temperature and for a length of time sufficient that will not cause oxidation. The resulting toasted groats have increased shelf stability with good organoleptic attributes and may be prepared for consumption by boiling in water.
