Abstract:
The present invention provides a method, a system, and a computer program product for configuring a Web portal for a computer-based application using one or more menus available in the computer-based application. It comprises classifying the menus available in the application according to the functionalities. The menus classified under each functionality are configured in a hierarchical structure for presenting on the Web portal corresponding to the functionality. A context bar is defined for the Web portal by defining at least one context element. Thereafter, mapping is defined for at least one field of one or more menus presented under the Web portal with one of the at least one context element. The mapping allows auto-filling of fields of an invoked menu with the value of the mapped context element, thereby reducing the manual effort of a user.
Abstract:
A system and method for tracking of advertisements. The system includes a user interface for accessing information associated with commercial breaks and advertisements. The system also includes one or more edge devices for recording advertisements aired during commercial breaks on a television or radio channel. Further, the system includes a media server. The media server includes a memory, and a processor for storing recorded advertisements along with a stamp of region, channel, program and time of insertion associated with the advertisements in a repository of a media server, and providing access to the recorded advertisements for the advertisers. The method includes recording advertisements aired during commercial breaks on the television or the radio channel, storing recorded advertisements along with a stamp of region, channel, program and time of insertion associated with the advertisements in a repository of a media server, and providing access to the recorded advertisements for the advertisers.
Abstract:
An adaptive receiver to provide reliable estimates of the symbols for the high-order MQAM and MPSK modulated signals received in the presence of amplitude fading and phase dynamics induced due to time-varying atmospheric or terrestrial multipath fading encountered in wireless communication channels. The adaptive receiver encompasses an adaptive tracking loop comprised of adaptive channel fade envelope estimator derived from the high-order modulated signal, a novel phase detector to separately estimate the phase due to the fading channel and the reference oscillator from that due to the data modulation present in the received signal without the need of any pilot symbol or pilot carrier, and a Kalman filter, a fixed-lag smoother and a smoothed symbol detector.
Abstract:
A method for pre-processing a signal prior to receipt of the signal by a non-linear device (NLD) to compensate for AM-AM distortion and AM-PM distortion of the signal by the NLD. The method includes generating a modified amplitude rk based on an amplitude xk derived from a digitized envelope Ri,k of the signal, generating a scale factor ck based on the modified amplitude rk and the amplitude xk, generating an AM-AM compensated signal based on the scale factor ck, generating a first AM-PM phase compensation value based on the modified amplitude rk, and generating an AM-AM and AM-PM compensated signal by modifying a phase of the AM-AM compensated signal based on the first AM-PM phase compensation value.
Abstract:
Various embodiments are directed to systems and methods for combining a plurality of codes. The plurality of codes may be binary codes having possible logical values of −1 and +1 and may comprise an even number of codes. An output of the combining v0,k may be given by: v0=sgn(vi), where vi is the sum of the first plurality of codes at the first time. Embodiments for allocating different power levels among various codes are presented.
Abstract:
Implants are made of materials having asymmetric modulus gradients. For example, an implant, such as a hip implant, is made of a material having a stiffness gradient between a proximal portion near a hip joint and a distal portion extending downward into the marrow of the femur. Among other benefits, the asymmetric modulus gradient mitigates problems associated with stress shielding and does not excessively wear or deteriorate the proximal portion of the implant.
Abstract:
A video layer effects processing system which receives normal video and special effects information on separate layers has been presented. The system selectively mixes various video layers to transmit a composite video signal for a video display such as a television, or a virtual reality system. Special effects include spotlights, zooming, etc. Additional special effects such as shaping of objects and ghost effects are created by masking and superimposing selected video layers. The selective mixing, for example, to enable or disable, strengthen or weaken, or otherwise arrange special effects, can be directed from a remote source or locally by a user through real-time control or prior setup. The video layer effects processing system can also be incorporated into a set-top-box or a local consumer box.

Abstract:
A decompression machine to be called SUDARSHAN CHAKRA is a better efficiency of energy conversion method than prior arts i.e. turbine, internal combustion engine & steam engine. Gas or liquid containing intermolecular forces from anywhere is harnessed & released intra-corporally & sequentially to get discharged tangentially from the blades which absorb the momentum of the propellant by pressure drops &/or velocity rises, in order to produce torque force resulting into rotations of axle, which can drive any other machine for production or transfer of energy. This is an action& reaction turbine. Here the idea is to produce circular motion from natural linear motion of the propellants like wind, gas, steam, water, hydrocarbon Etc.
