A method is provided for allocating bandwidth to a subscriber in a service provider domain that is part of a packet switched network such as the Internet, for example. In accordance with the method, a number of shares of bandwidth are assigned to the subscriber based on an agreement between the subscriber and a service provider. A subscriber identifier and the number of shares assigned thereto are distributed to the routers in the domain of the service provider. The routers will in turn allocate bandwidth to packets they receive based on the number of shares assigned to the subscriber transmitting or receiving the packet. The subscriber may include one or more different user terminals that aggregate traffic onto a single datastream. The shares assigned to the user may denote absolute amount of bandwidth, or alternatively, may denote a relative bandwidth allocation.

Disclosed is a processor-implemented method for processing image data comprising a plurality of pixels and system for performing the method. The method includes the following acts: determining at least one type of data represented by the plurality of pixels, determining, for each type of data, a number of pixels from the image data representing that type of data in the image data, and determining a compression scheme for compressing the image data based on a relative or absolute amount of each type of data in accordance with a predetermined scheme. The type of data may be determined by received input (e.g., user selected type and compression quality) or by analyzing its pixels and comparing it to thresholds. Basing the compression technique on the data type allows for better selection of a compression technique (e.g., MRC or JPEG), and thus greater image quality, compression ratios, and file size.

Methods and apparatus for analyzing a test sample using complementary techniques, such as x-ray fluorescence (XRF) and optical emission spectroscopy (OES), are disclosed for registering two or more test instruments, in relation to the test sample, such that each of the instruments analyzes substantially the same region as is analyzed by the other instrument(s), and for communicating analytical results between or among the instruments, or between the instruments and another component, to enable one or more of the instruments, or the other component, to combine the results and, thereby, more completely and accurately determine the composition of the test sample. Such registration and communication enables, for example, separate XRF and OES instruments to collectively determine the composition of the test sample, including the absolute amounts of light and heavy elements in the test material.

The invention detects the thickness error of the transparent substrate using a general focus error signal detection system employing the fact that the reflecting light from the optical disk causes distortions in diffraction image at the detection plane or unsymmetrical expansions before and after the detection plane due to spherical aberration as a result of thickness errors of the transparent substrate. The absolute amount of the thickness error of the transparent substrate and its symbol are detected by detecting the difference between the absolute value of the positive side peak and the absolute value of the negative side peak of the focus sum signal, or the difference in focus positions between the peak point of the focus sum signals and the zero point of the focus error signals using the focus error signal detection system according to the knife-edge method. This enables it to detect the thickness error of the transparent substrate without using a special optical system.

More “timing closure efficient” Timing Driven Placements by implementing our new net weight for negative slack paths to enhance timing closure behavior is provided by a NSRF (Negative Slack Recover Factor). This new weight would not be based on the absolute amount of negative slack in a path, but rather it would be based on the proportion or percentage of the path's total net delay adder that must be recovered in order to achieve timing closure (zero slack). After an initial or previous placement has been created, then a list of paths with timing violations with a Negative Slack Recover Factor (NSRF) is created for each net in each of the timing paths on the list of paths, and then calculating a NSRF net weight factor for use in subsequent placements and also assigning nets in the list of paths with no timing violations a NSRF default value of one.. The NSRF value is calculated as equaling (ZWLM slack value +negative slack value)/ZWLM slack value=(1+(negative slack value/ZWLM slack value)), where ZWLM is a Zero Wire Load Model (ZWLM) value of timing wherein all wire parasitics are removed from consideration in the timing.

In a packet communication system with large bandwidth delay product (BDP) and employing Transmission Control Protocol (TCP), the reported advertised window size as advertised by a receiver is employed only as an indication of window size and not as a throughput limit so that more data is sent than the amount specified by the advertised window size. Since the receiver can process all incoming TCP packets, the receiving buffer is consistently near empty. Since the TCP's advertised window size is not accepted as the absolute amount of buffer space available at the receiver, the sender is not constrained by the absolute value of the receiver's advertised window size and instead can transmit more data than the absolute value of the advertised window, enabling the system to increase the actual window size without modifying the link ends. This improved large-BDP-capable protocol is denoted TCP-SC.

A computational scheme for an INS which utilizes micro-electro mechanical systems (MEMS) sensors is disclosed resolving issues of unnecessarily large computational burden and numerical instability which happen in using conventional methods using high-end inertial sensors. The first aspect to reduce computational burden in MEMS application is to omit computing Earth radii of curvatures that were used in a high-frequency application. The second aspect is to ignore the Earth rotation and the rotation of the local tangent plane with respect to Earth in the computation which are much smaller than noise and bias in the MEMS sensor output. The last aspect is to assume that the absolute amount of the platform pitch and roll angles is less than 90 degrees. This assumption results in only four parameters required to track in the direction cosine matrix describing the transformation from the local tangent plane to the platform where all the nine elements are tacked in the conventional method. According to the aspects noted above, the computational load will be one-fourth of the conventional method without degradation of accuracy.
