An embodiment of a method of controlling access to a computing resource within a shared computing environment begins with a first step of determining a plurality of controller functions for a plurality of operating ranges for workloads accessing the computing resource. Each of the controller functions comprises a mathematical operator which takes an input and provides an output. The method continues by iteratively performing second through fifth steps. In the second step, the method measures performance parameters for the workloads to determine a performance parameter vector for the workloads. In the third step, the method compares the performance parameter vector to a reference performance parameter vector to determine an error parameter. In the fourth step, the method applies a particular controller function selected from the plurality of controller functions to the error parameter to determine a target throughput for each of the workloads. In the fourth step, the method adjusts access to the computing resource for each of the workloads having a throughput limit different from about the target throughput for the workload by reducing or increasing the throughput limit for the workload to about the target throughput.

The present invention provides a Data Entry Device for computers and other devices. An embodiment of the present invention provides a Data Entry Device combining a keyboard and pointing device for computers and other devices; The Data Entry Device of the present invention introduces a completely new ergonomic construction for all keys. In the Data Entry Device of the present invention the keyboard and pointing device can both be used without shifting the hands from its initial resting position and where the shift key has to be used only for capitals and a few rarely used punctuations and symbols. The vowels are all on one side thus making them easy to access and use. All the letters are arranged so that on maximum occasions the letters are alternating between hands. The character keys are separated into alphabets, numerals, mathematical operators, punctuations and symbols. The placement of the characters on the DED is based on their frequency of occurrence in the environment, the ideal workload that should be allotted to each finger, the order of ease of use of keys, their pattern of use and similarity of type. In the present invention the concept of Home Row for fingers has been replaced by Home Keys for each finger being the keys on which the fingers tend to rest naturally and is not in one row. All this together makes the DED easy to comprehend, easy to learn, easy to use, more difficult to forget, increase the speed of typing, reduce errors and makes the user less prone to medical problems.

Efficient LDPC code decoding with new minus operator in a finite precision radix system. A new mathematical operator is introduced and applied to the decoding of LDPC coded signals. This new operator is referred to as the min†− (min-dagger minus) operator herein. This min†− processing is appropriately applied during the updating of the edge messages with respect to the variable nodes. In a bit level decoding approach to decoding LDPC coded signals, the updating of the edge messages with respect to the bit nodes is performed using the new min†− operator. This approach provides very comparable performance to min** processing as also applied to updating of the edge messages with respect to the bit nodes and may also provide for a significant savings in hardware. Also, within finite precision radix systems, the new min†− operator provides a means by which always meaningful results may be achieved during the decoding processing.

A first frequency allocation is determined, and mathematical operators are used to determine at least one further frequency allocation from the first frequency allocation. A frequency hopping sequence is then determined, including the first frequency allocation, and the or each further frequency allocation. A network node may perform the allocation method, and a user equipment may operate using the allocated bandwidth.

A method, system, and computer software product for operating a collection of memory cells. Each memory cell in the collection of memory cells is configured to store a binary multi-bit value delimited by characteristic parameter bands. In one embodiment, a transforming unit transforms an original collection of data to a transformed collection of data using a reversible mathematical operator. The original collection of data has binary multi-bit values arbitrarily distributed across the binary multi-bit values assigned to the characteristic parameter bands and the transformed collection of data has binary multi-bit values substantially uniformly distributed across the binary multi-bit values assigned to the characteristic parameter bands.

Ground truth for a cognitive system is generated from a structured resource such as a table by identifying a subject of the structured resource and field headers. Linguistic analysis is performed on a given header to establish an interrogative context, and a question is generated relating to the subject based on the interrogative context, including an implementation of one or more mathematical operators. The question is generated using a question template, and has a question phrase based on the interrogative context, an operator phrase based on the selected operator, and a keyword phrase based on the subject. An answer to the question is determined by carrying out a computation that applies the selected operator(s) to one or more of the data values, to form a question-and-answer pair that is added to the ground truth. A filtering step is preferably used to ensure that the question-and-answer pair is valid.

The invention relates to a method for performing voiceprint verification of Chinese through single arithmetic.
