摘要:
In a client-server architecture, data transmission performance enhancing features and mechanisms are described, including a color quality approach and a packet shaping approach. A method includes a color quality data transformation including: selecting a quality level to apply to a set of image data having a number of significant color bits defining an initial number of possible colors; applying a pixel mask to the set of image data, the initial number of possible colors reduced to a smaller number of possible colors as a function of the quality level; loading the set of image data into an output buffer; and sending the set of image data from the output buffer to a display engine. Another method includes a packet shaping data structure transformation including if i) a total network time, defined by a total time of requests in a pending request queue, is equal to or greater than a current round trip time, defined by twice a current latency, and ii) a total request time, defined by a sum of a total time of requests in the pending request queue and a total time of requests in a transmitted request queue, minus the total network time is equal to or less than half a preset limit, then forming a shaped packet by associating a first data portion with a second data portion and a header.

In a client-server architecture, an Adaptive Internet Protocol (AIP) system, comprised of a display engine operating on a server and a protocol engine operating on a server, provides means to support standard graphics based computer applications connected to clients of varying capability via a network of varying bandwidth and latency by automatically varying the type and number of graphic requests and their networking encoding to provide near optimum performance while maintaining the correct visual representation.

The present invention relates to certain novel substituted ketones which are 1-pyrimidinylacetamide derivatives of formula I, ##STR1## set out herein, which are inhibitors of human leukocyte elastase (HLE), also known as human neutrophil elastase (HNE), making them useful whenever such inhibition is desired, such as for research tools in pharmacological, diagnostic and related studies and in the treatment of diseases in mammals in which HLE is implicated. The invention also includes intermediates ##STR2## useful in the synthesis of these substituted ketones processes for preparing the substituted ketones pharmaceutical compositions containing such substituted ketones and methods for their use.

摘要:
Various embodiments monitor compliance with standards for conducting rounds within corrections facilities and assist in maintaining safe corrections facilities by identifying predictable rounds patterns and encouraging inmate monitoring through unpredictable rounds timing. Some embodiments generate scores indicative of randomness in conducting rounds by individuals, groups, and even an entire staff of corrections officers.

Described herein are variants of H. jecorina CBH I, a Cel7 enzyme. The present invention provides novel cellobiohydrolases that have improved thermostability and reversibility.
摘要:
Hybrid alpha-amylases are provided that share a conserved 3D structure in whole or in part with a wild-type Termamyl-like ?-amylase, e.g., a Bacillus amylase. In the hybrid, an N terminal portion of a Termamyl-like ?-amylase is replaced with sequences from an archae ? amylase. The sequence similarity between the two amylase sequences may be less than 60%. Conserving the wild-type 3D structure in the hybrid facilitates obtaining enzymatically active amylases. In one embodiment, one or both amylase sequences contribute residues to the B domain, resulting in particularly advantageous properties. For instance, replacement of the Ca2+ binding site in the B domain of the Termamyl-like ?-amylase with a B domain sequence of an archae ? amylase that does not bind Ca2+ can produce a hybrid that is fully active in the absence of Ca2+.
