Abstract: The invention provides a process for removing carbon dioxide from a gas stream comprising the steps of: (a) contacting the gas stream with an absorption solvent to obtain a gas stream with a reduced carbon dioxide content and a carbon dioxide-containing absorption solvent; (b) withdrawing at least part of the gas stream with the reduced carbon dioxide content; (c) withdrawing at least part of the carbon dioxide-containing absorption solvent obtained in step (a) and heat it to obtain a mixture comprising a gas phase, an aqueous liquid phase and a non-aqueous liquid phase, wherein carbon dioxide is predominantly present in the gas phase; (d) introducing at least part of the mixture obtained in step (c) into a gas lift reactor to further release carbon dioxide absorbed in the aqueous liquid phase and the non aqueous liquid phase, whereby the gas phase establishes circulation and mixing of the aqueous liquid phase and the non-aqueous liquid phase between a lower section of the gas lift reactor and an upper sectio

Abstract: Multiplexed traffic in a system where the maximum rate of all inputs exceeds the maximum rate of the output is processed via a separate queue for each input, and at any given forwarding clock cycle the earliest enqueued packet is forwarded via the output. In the event of congestion, a proportionally equal number of packets are dropped from each queue, where proportional equality corresponds to the number of packets dropped per number of packets enqueued. One implementation associates a time-stamp with each enqueued packet to indicate the time of enqueing relative to other enqueued packets. At any given forwarding clock cycle, the packet with the earliest time-stamp is forwarded.

Abstract: A Balanced Packet Transmit Opportunity (BPTO) mechanism allows balanced bandwidth traffic to be serviced while still maintaining the service levels desired for high priority traffic. The above embodiment achieved the result by distinguishing both queue types and slot style types, and performing selections differently depending upon the relative styles of the queues and slots. This arrangement provides a number of advantages. Because the selection method is fast and relatively simple to implement, a large number of queues may be integrated into the decision process while maintaining a desired output bandwidth. In addition, the selection process provides a flexibility, allowing multiple traffic shaping considerations to be modified during operations to support changing network requirements.

Abstract: Telephone (installed and mobile) and pager billing statements can be significantly enhanced if the call log information was summarized and presented by visual means, such as maps. A method and system is described herein to deliver telephone and pager call log details through one or more maps embedded within or provided with telephone and pager billing statements. Beyond the traditional tabular call log list, the invented system offers maps, which display the physical locations relevant to calls geo-referenced to a map (location of placement and reception). Calls are represented in the map either individually and/or are summarized by the number of calls, the timing of the calls, the charges applied to the calls, the call categories (incoming, outgoing, daytime, nighttime, peak time, off peak time etc.), local-area and none-local-area calls, sensitive calls, geographic unit, or any combination thereof.

Abstract: A model is given for performance evaluation of IP computer networks that are dominated by congestion-controlled traffic.

The performance of large-scale networks is estimated where flows may encounter multiple congested links.

Abstract: A method and system is described herein to summarize and present charge-card transactions through one or more maps linked to charge-card billing statements. In addition to a conventional tabular transaction list, the invented system provides charge-card transaction maps, which display the physical location of points-of-charges geo-referenced to a map. Transactions are listed individually and/or are summarized by the number of transactions, the timing of transactions, the amount of transactions, the transactions categories, local-area and none-local-area transactions, sensitive transactions, geographic unit, or any combination thereof. The method and system integrates database and geographic information system technology with a rule system.

Abstract: An analysis and unusual event detection method is presented herein that was developed systematically for bio-intelligence in the area of syndromic surveillance using over-the-counter (OTC) pharmaceutical sales data. First, a measurement scheme was defined. It bases on historical sales records and a set of derived seasonally varying reference lines. The relative deviation (RD) of the current daily medicine sales data from the reference lines, the n-days cumulation of the relative deviations, and the daily change of the relative deviations are calculated. Second, a dynamic system model for categorized public health status was developed and described by a set of state variables and state transitions. State transitions are determined by a rule system. The combination of the quantitative measurements listed above establishes the supporting set for the rule system. Therefore, the dynamic change of public health status is systematically modeled over time and space by rule-system-driven state transitions.

Abstract: An apparatus and method of managing received packets to be transmitted from a network device stores the received packets on one of two different buffers. In particular, the received packets are one of a first type of data packet and a second type of packet. Each one of the first type is stored in a first buffer having a first drop function, while each one of the second type is stored in a second buffer having a second drop function. Each respective drop function specifies a packet drop rate as a function of the average number of packets in its respective buffer. The first drop function has a first average drop rate over a specified time interval, while the second drop function has a second average drop rate over the specified time interval. The first average drop rate and the second average drop rate have a predefined relationship. Accordingly, if the two drop rates do not comply with the predefined relationship, then at least one of the two average drop rates are modified.
