Blocking the chain

2018
Smart Farming, Drohnen, per Satellit gesteuerte Traktoren, die Nutzung von Klima- und Wetterdaten durch Big Data oder die Anwendung von synthetischer Biologie: Ist die Digitalisierung von Landwirtschaft und Ernährung tatsächlich das neue Wundermittel, um Hungerkrisen zu beenden, den Verlust an Biodiversität zu stoppen oder den Klimawandel aufzuhalten ...

Chain Segregation in Block Copolymers

1989
The mixing of two different homopolymers leads in most cases to a two-phase blend. The main reason for this behaviour is that the combinatorial entropy of mixing is very small for chain molecules and specific interactions are required to achieve miscibility.1 Such two-phase blends are generally characterized by opacity, distinct thermal transitions for

Prime-Partitioned Block Chain: A Scalable and Efficient Block Chain Implementation

SSRN Electronic Journal, 2017
A new method to construct a distributed, highly scalable and computationally efficient block chain is proposed. The primary focus is on designing a network that can scale efficiently to any number of nodes and add blocks at a very high rate, while still ensuring that the information stored in the block chain can be speedily verified.

The Nature of Block Chain Intelligent Contract

2020 15th International Conference on Computer Science & Education (ICCSE), 2020
block chain smart contract is the third stage of the development of smart contract, but also the second stage of the development of block chain. The discussion of the nature of the contract law of block chain intelligent contract should take the contract-based intelligent contract as the research object.

A chain heuristic for the Blocks Relocation Problem

Computers & Industrial Engineering, 2014
In the Blocks Relocation Problem (BRP) one is given a block retrieval sequence and is concerned with determining a relocation pattern minimizing the total number of moves required to enforce the given retrieval sequence. The importance of the BRP has been constantly growing in recent years, as a consequence of its close connection with the operations ...

Explanation of Block Chain

International Scientific Journal of Engineering and Management
Abstract:This project is aimed to develop a blockchain-based eVault system for legal records that can ensure security, transparency, and accessibility for all stakeholders. By leveraging blockchain technology, the project creates a transparent and immutable record of all actions and changes made to legal documents.

Main-chain supramolecular block copolymers

Chem. Soc. Rev., 2011
Block copolymers are key building blocks for a variety of applications ranging from electronic devices to drug delivery. The material properties of block copolymers can be tuned and potentially improved by introducing noncovalent interactions in place of covalent linkages between polymeric blocks resulting in the formation of supramolecular block ...

Modified forms of cipher block chaining

Computers & Security, 1991
A long-standing proposal for modifying cipher block chaining to prevent data expansion is shown to be insecure in some circumstances. Different modifications are then presented which appear secure.

Efficient error-propagating block chaining

1997
This document presents EPBC, Efficient Error-Propagating Block Chaining, a new and efficient block encryption mode using both plaintext and ciphertext feedback. This encryption mode is similar to another one, IOBC, and was likewise designed to propagate erroneous decryptions of tampered blocks of ciphered data to all following blocks, hence allowing to
