摘要:
The present invention provides an improved selective hydrogenation process for removing C10-C16 diolefins in the product from dehydrogenation of C10-C16 paraffins to mono-olefins, which process includes bringing the mixture stream of paraffins and olefins containing C10-C16 mono-olefins and C10-C16 diolefins into contact with a specific hydrogenation catalyst in a plurality of hydrogenation reactors connected in series under the reaction conditions for hydrogenation. Hydrogen is injected into each reactor respectively. To convert the diolefins in the mixture stream of paraffins and olefins into mono-olefins, &ggr;-alumina having a specific surface area of 50-300 m2/g and a pore volume of 0.2-2.0 cm3/g is used as the supporter of the hydrogenation catalyst, palladium is supported on the supporter as the main catalyst element and an element selected from silver, gold, tin, lead or potassium is supported on the supporter as the promoter.

An example apparatus, such as a position server, is caused to receive proximity information from a number of mobile apparatuses located remote from the apparatus, and receive observed current locations from at least some but not all of the mobile apparatuses. The apparatus is also caused to determine a proximity relation between certain ones of the number of mobile apparatuses, where the proximity is reflected by the proximity information received from the mobile apparatuses. And the apparatus is caused to calculate an estimate of a current location of at least one of the one or more remaining mobile apparatuses as a function of the proximity relation between certain ones of the number of mobile apparatuses, and as a function of the observed current locations of the one or more mobile apparatuses.

An external capability for measuring roundtrip latency in a conferencing system is provided. The external capability for measuring roundtrip latency in a communication system may include functions of generating a content event, detecting the content event in a received content stream including the content event, determine a first time associated with generation of the content event and a second time associated with detection of the content event, and computing a roundtrip latency based on a difference between the second time and the first time. The content event may be a visual event or an aural event. These functions may be implemented using one or more modules or elements. A computing device may be used to generate and detect the content event and to compute the roundtrip latency. Various other arrangements of modules or elements may be used to provide the functions.

A method and system is designed and implemented to allow users to share their online activities with family members, friends, colleagues, neighbors, merchants, advertisement sponsors, and other people, while still concentrating on their own tasks on the internet. The system also provides online forums, profile-based advertisement auction, group-based mobile e-commerce, and other facilities, so members in a group can communicate and interact among themselves. The automatic sharing of user activities is realized by software extensions or plug-ins that are embedded in a web browser. The users can submit their activities to multiple groups, selected by a click on the icons of groups. The automatic sharing aspect of the proposed system has been implemented, and the proposed functions have been successfully tested. The mechanisms that are proposed and described in detail include profile-based advertisement auction on individual users, group-based mobile e-commerce, and community-based innovation incubator.

摘要:
The present invention provides an acoustic attenuation based on sound ray deflection theory and a muffler. The method of the present invention provides a temperature gradient between the interior and the exterior of the chamber of the muffler through the low temperature refrigeration system, in which the temperature inside the pipe wall is higher than that outside the pipe wall. The said temperature gradient may deflect the acoustic ray towards the low temperature direction, so as to capture and reduce the noise. The muffler of the present invention comprises a muffler housing laid with a sound absorbing structure (4) on its internal surface, is characterized by the low temperature refrigerating system (2) which is fixed in the position corresponding to the sound absorbing structure (4) on the external surface of the muffler housing (1), covers at least 5% of the area of the external surface of muffler housing (1), and is used to realize quantitative control of the temperature gradient together with a temperature control system (3). The muffler of the present invention effectively improves the noise-absorbing effect of the prior muffler.
