Recursive Data Compression Method

Authors: John Archie Gillis
Comments: 22 Pages.

Recursive compression of random data is generally deemed to be an impossible process that defies the laws of physics (Shannon Entropy). This paper explains why this perception is incorrect and provides a proof that explains how such a compression system may be achieved. The practicality of the method has yet to be determined.

P=NP Methods of Organizing Data

Authors: John Archie Gillis
Comments: 37 Pages.

The present methods take a novel approach to solving NP-Complete problems and provide steps that a computational device and software program can follow to accurately solve NP-class problems without the use of heuristics or brute force methods.

Biconch Chain: A New Distributed Web Protocol Based on an Innovative Proof of Reputation (PoR) Consensus Algorithm and Eco System

Authors: Caesar Chad, Neo Liu, Leon Lau, Joseph Sadove
Comments: 34 Pages.

BITCONCH chain proposed an innovative POR (Proof Of Reputation) reputation consensus algorithm, which solved the pain point that the blockchain is difficult to maintain both high throughput and decentralization. Based on social graphs, BITCONCH Chain mathematically models social, time, and contribution activities to build a decentralized reputation system. Each user has the opportunity to establish a high reputation value. The higher the user's reputation, the lower the transaction cost (or even free). The more opportunities that are selected as trust nodes to participate in the consensus, the greater the benefits. High-reputation users are defined as “mutual trust nodes”, and small micro-transactions will start “payment channels” for high-speed offline transactions. The reputation system and system incentive system will effectively promote the continued enthusiasm of business developers and ordinary users, and contribute to the construction of the business ecosystem. Business developers with traffic are more likely to get high reputation values, and the chances of being elected to a trusted full node are higher. Ordinary users can increase reputation by actively engaging in social interactions and actively using business applications in the ecosystem, increasing the chances of being selected as trusted light nodes. The Bitconch chain uses a DAG directed acyclic graph data structure to maintain the system's positive scalability. Support smartphone light node client to resist the decentralization of the system and maintain dispersion. Zero-knowledge verification, latticed data storage, quantum-level encryption algorithms, and improved BVM virtual machines make Bitconch chain more reliable and provide a friendly DApp and sidechain development environment to meet certain applications. Technical requirements for large file storage, low transaction costs, user information protection, sidechain and smart contract iterations, and bug fixes. BITCONCH chain is a decentralized distributed network with no block and no chain, which solves two difficulties in the application of blockchain: scalability and decentralization. Bitconch chain, which can be applied to the commercial application needs of users above 10 million, is the most feasible blockchain ecosystem for high-frequency small micro-transactions and social applications.

Algorithm to Improve Information Security

Authors: George Rajna
Comments: 53 Pages.

Cryptography is a science of data encryption providing its confidentiality and integrity. [33] Researchers at the University of Sheffield have solved a key puzzle in quantum physics that could help to make data transfer totally secure. [32] "The realization of such all-optical single-photon devices will be a large step towards deterministic multi-mode entanglement generation as well as high-fidelity photonic quantum gates that are crucial for all-optical quantum information processing," says Tanji-Suzuki. [31] Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. [30] A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the topologies of core electron orbitals of organic molecules and their silicon analogues. [29] A University of Central Florida team has designed a nanostructured optical sensor that for the first time can efficiently detect molecular chirality—a property of molecular spatial twist that defines its biochemical properties. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26] Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal. [25] This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology. [24]

Enhancing Website Navigation by User Experience Design Strategies

Authors: Pedram Ahmadi
Comments: 121 Pages.

Today Designing efficient interfaces plays an important role in world wide web. People are highly attracted to websites that gives them more useful information at lowest time intervals. Websites always have a lack of enough strategies to keep users involved and satisfied. Now user experience design comes up to mind to solve these difficulties with new ideas and practices. The UX Design uses usability and accessibility methods to improve the interaction between users and websites. This thesis focuses on web navigation types to make them more appropriate in the way of providing useful contents.

A Heuristic Algorithm for the Solution of SAT in Polynomial Time

Authors: Valdir Monteiro dos Santos Godoi
Comments: 40 Pages. A primeira versão deste artigo foi meu trabalho de Métodos em Pesquisa Operacional (PM015), IMECC-UNICAMP.

Usando um novo conceito de linguagem variável, já provei anteriormente que P≠NP, mas tal prova não utilizou nenhum dos problemas clássicos conhecidos como NP-completos, a exemplo de SAT (satisfatibilidade, satisfiability), caixeiro-viajante (travelling-salesman), soma de subconjuntos (subset-sum), da mochila (knapsack), programação linear inteira (integer linear programming), etc. Tal prova não implica que sendo P≠NP então devemos ter NP-completo ∉P, ou seja, os mencionados famosos problemas difíceis podem ainda ser resolvidos em tempo polinomial, sem precisar encerrar a pesquisa nesta direção. Tal como ocorre com o método simplex, que pode resolver em tempo polinomial a grande maioria dos problemas de programação linear, também é possível resolver SAT em tempo polinomial na maioria das vezes, que é o que eu mostro neste trabalho.
