In general, this disclosure is directed to techniques for memory efficient and low complexity adaptive variable length coding (VLC) of data for a variety of applications, such as coding of digital video, image, audio, or speech data. In some aspects, the techniques may exploit properties of ...
The proposed TCBC is shown to be useful in a varietyof applications including forward error correction, low rate quasi-orthogonal sequence generation, lattice code construction, etc. Moreover, the encoder and decoder for TCBC are realized using off the-shelf trellis and block encoders and trellis...
Not all blockchains are 100% impenetrable. They are distributed ledgers that use code to create the security level they have become known for. If there are vulnerabilities in the coding, they can be exploited. A new and smaller chain might be susceptible to this kind of attack, but the at...
so it began recording all processes and actions, from vendor to customer, and coding them into smart contracts on a blockchain. This effort not only made it easier to trace the provenance of food for safer consumption but also required less human effort and improved the ability to track lost...
SINGAPORE, March 11, 2025 /PRNewswire/ -- In a development that aligns perfectly with the surging popularity of "vibe coding"—the emerging trend of creating applications based on feeling and intention rather than technical specifications,Dominic Williams the Chief Scientist of DFINITY Foundation .....
The validation process ensures the data is unique and legitimate with timestamps to prove it. Should someone try to swap out a block, copy it or change its state, the network of computers that constitute the blockchain receives an alert immediately and no one can add new blocks to the cha...

Moreover, they can automate a sequence of actions so that when specific conditions are met, the subsequent actions are performed. Smart contracts on a blockchain operate by utilizing simple conditional statements, such as “if/when …else/then”, encoded into the code. When certain predetermined...
These blocks form a chain of data as an asset moves from place to place or ownership changes hands. The blocks confirm the exact time and sequence of transactions, and the blocks link securely together to prevent any block from being altered or a block being inserted between two existing bloc...
