A business method is disclosed directed to attempting to saving clients money on their communications services. Specifically, billing information is obtained for a client and loaded into a database. An initial rate is determined based on this billing information, along with possibly an add on rate for add on services, which can provide a combined rate charge. At least one of the initial rate and combined rates are compared to a derived rate which is calculated by applying an algorithm to the database which applies the actual data to a plurality of rate plans provided by communications carriers to see which rate plan might provide savings for the client, if any. If savings are achieved, at least recommending if not switching to another rate plan, possibly of an other carrier.

The invention discloses an attitude control system for space vehicle and a method thereof. The control system has only one biased momentum wheel, one set of tri-axial magnetic torquer and one attitude controller loaded with algorithm. The method comprises a step of rate damping controlling, a step of initially capturing controlling and a step of stationarity controlling. At the rate damping stage, geomagnetism change is used to control the magnetic control of three passages of a satellite by B-dot; at the initially capturing stage, the magnetic control is realized, PD control is performed by pitching and the passages are rolled and yawed to carry out nutation and precession composite control; at the stationarity controlling stage, the magnetic control is realized, PD control is performed by pitching and the passages are rolled and yawed to carry out nutation and precession composite control. The capturing stage and the stationarity controlling stage fully depend on magnetic torquer to perform positive magnetic control, thereby changing which a satellite only uses a magnetic torquer to carry out unload of the momentum wheel or auxiliary magnetic control, so as to refine system configuration to further improve reliability of the system. Momentum of a satellite is biased to rotate on the ground, so as to ensure stable separation of the satellite without performing air injection control. Therefore, the magnetic torquer can be used for realizing fast and stable initial rate damping.

Mixed-phase TiO2 nanofibers prepared via a sol-gel technique followed by electrospinning and calcination are provided as photocatalysts. The calcination temperature is adjusted to control the rutile phase fraction in TiO2 nanofibers relative to the anatase phase. Post-calcined TiO2 nanofibers composed of 38 wt % rutile and 62 wt % anatase exhibited the highest initial rate constant of UV photocatalysis. This can be attributed to the combined influences of the fibers' specific surface areas and their phase compositions.

Methods and apparatus are disclosed for an adaptive rate control mechanism reactive to flow control messages in a packet switching system and other communications and computer systems. Typically, a multiplicative increase and exponential decrease technique is used to throttle traffic. Backpressure feedback is used to calculate the initial rate at which to allow traffic after backpressure is deasserted. This reduces the probability of underrun of buffers (e.g., too little traffic being carried). The adjustment to the initial rate is made by measuring the time between the XON and XOFF in factor periods. Then a target XON time is subtracted. If the result is positive (i.e., the measured XON time was too long), the rate is multiplicatively increased (e.g., by a factor of two to the difference). If the result is negative (i.e., the measured XON time was too short), the rate is exponentially decreased (e.g., by the square root).

The invention provides a method for combined estimation of the SOC and the SOH of batteries in a multi-scale frame. The method takes the SOH change in the storage process and the reuse process of lithium ion batteries into consideration, and the calculation quantities of the SOC and SOH estimation algorithms are reduced, so that the estimation accuracy is improved.

An automated simulator for radar and sonar applications. The inventive simulator is implemented in hardware and generates current parameters with respect to a simulated target in response to a plurality of initial values with respect thereto. In the illustrative embodiment, the initial values include range, velocity, and acceleration and are stored in first, second and third register respectively. In the best mode, the invention is implemented in a field-programmable gate array. The inventive target simulator also includes a range delay circuit for generating a simulated return from the simulated target. The range delay circuit includes logic for determining whether a simulated pulse train to be received is ambiguous or unambiguous and adjusting the pulse repetition rate of the pulse train accordingly. The range delay circuit calculates die initial time that a packet needs to make the trip to and from the target. Then, in the ambiguous case, the circuit only calculates how long it takes between pulses to arrive rather than the entire round trip. When the round trip distance and the ambiguous time are identical, the range delay circuit calculates both ambiguous and unambiguous signals and signals the return of whichever type arrives first. After the initial rate is calculated then the shortest calculation between the ambiguous and unambiguous pulses determine the timing for the next returned pulse.
