Distributed Blockchain Processing
0 likes865 views
The document discusses distributed blockchain processing and some of the challenges involved. It addresses issues like race conditions when sharing resources across distributed systems and consistency problems that can arise. It proposes using a distributed hash table (DHT) combined with a blockchain to help control consistency across nodes. This could provide benefits like uniformly distributing transactions across nodes, weakening the dependency of execution time on the number of nodes, enabling real-time transactions, and allowing the blockchain to be independently validated. The approach aims to help address issues like consistency when replicating data or operations over distributed resources.

What is MultiChain Technology?
What is MultiChain Technology?Blockchain Council MultiChain technology allows organizations to establish private blockchains using a simple API and command line interface. It ensures transactions only occur between validated participants of the chain to maintain stability and control. The mining process is made safer through proof of work and costs. Handshaking occurs when nodes connect and exchange permission lists, aborting if results are unsatisfactory. Mining diversity establishes a rotation schedule for accurate block generation across permitted miners. Transaction fees and block incentives can be configured in the params.dat file along with other chain settings.

Blockchain technology Overview
Blockchain technology OverviewLalitha Prasanna This document provides an overview of blockchain technology. It discusses how blockchain can provide an alternative to centralized ledgers for storing transaction records. Key points made include:
- Blockchain uses a distributed ledger that is shared across a network of nodes and updated through consensus, eliminating the need for a centralized authority.
- Information stored on the blockchain is hashed and encrypted, providing security. New blocks are added through proof-of-work mining which involves solving computationally difficult puzzles and is incentivized with cryptocurrency rewards.
- Ethereum is a popular platform for building decentralized applications on blockchain through the use of smart contracts, which allow for automated execution of agreements.
- Potential use cases of blockchain include banking,
Distributed systems and blockchain technology
Distributed systems and blockchain technologyAlket Cecaj Blockchain is a distributed ledger system where nodes work together to validate transactions in a coordinated fashion without a central authority. It allows for decentralized consensus through mechanisms like proof-of-work. The main challenges in distributed systems are coordination between nodes and achieving fault tolerance. The CAP theorem states that a distributed system cannot achieve consistency, availability, and partition tolerance simultaneously. Blockchain sacrifices consistency for availability and partition tolerance. It uses elements like addresses, transactions, blocks, and consensus mechanisms like proof-of-work to securely and immutably record transactions on the distributed ledger.

01 what is blockchain
01 what is blockchainBastianBlankenburg Blockchain is a distributed ledger technology that allows for the safe distribution of a ledger across multiple nodes. It works by having each transaction digitally signed and added in a "block" along with a proof of work. This prevents double spending and allows nodes to reach consensus on the transaction history without a centralized authority. Smart contracts enable decentralized applications to run transactions automatically according to the program. However, first generation blockchains face challenges around centralization, scalability, and smart contract quality. New solutions aim to address these through alternative consensus methods, off-chain transactions, and designed smart contract languages.

Structural Response of Reinforced Self-Compacting Concrete Deep Beam Using Fi...Journal of Soft Computing in Civil Engineering Analysis of reinforced concrete deep beam is based on simplified approximate method due to the complexity of the exact analysis. The complexity is due to a number of parameters affecting its response. To evaluate some of this parameters, finite element study of the structural behavior of the reinforced self-compacting concrete deep beam was carried out using Abaqus finite element modeling tool. The model was validated against experimental data from the literature. The parametric effects of varied concrete compressive strength, vertical web reinforcement ratio and horizontal web reinforcement ratio on the beam were tested on eight (8) different specimens under four points loads. The results of the validation work showed good agreement with the experimental studies. The parametric study revealed that the concrete compressive strength most significantly influenced the specimens’ response with the average of 41.1% and 49 % increment in the diagonal cracking and ultimate load respectively due to doubling of concrete compressive strength. Although the increase in horizontal web reinforcement ratio from 0.31 % to 0.63 % lead to average of 6.24 % increment on the diagonal cracking load, it does not influence the ultimate strength and the load-deflection response of the beams. Similar variation in vertical web reinforcement ratio leads to an average of 2.4 % and 15 % increment in cracking and ultimate load respectively with no appreciable effect on the load-deflection response.

"Boiler Feed Pump (BFP): Working, Applications, Advantages, and Limitations E...Infopitaara A Boiler Feed Pump (BFP) is a critical component in thermal power plants. It supplies high-pressure water (feedwater) to the boiler, ensuring continuous steam generation.
⚙️ How a Boiler Feed Pump Works
Water Collection:
Feedwater is collected from the deaerator or feedwater tank.
Pressurization:
The pump increases water pressure using multiple impellers/stages in centrifugal types.
Discharge to Boiler:
Pressurized water is then supplied to the boiler drum or economizer section, depending on design.
🌀 Types of Boiler Feed Pumps
Centrifugal Pumps (most common):
Multistage for higher pressure.
Used in large thermal power stations.
Positive Displacement Pumps (less common):
For smaller or specific applications.
Precise flow control but less efficient for large volumes.
🛠️ Key Operations and Controls
Recirculation Line: Protects the pump from overheating at low flow.
Throttle Valve: Regulates flow based on boiler demand.
Control System: Often automated via DCS/PLC for variable load conditions.
Sealing & Cooling Systems: Prevent leakage and maintain pump health.
⚠️ Common BFP Issues
Cavitation due to low NPSH (Net Positive Suction Head).
Seal or bearing failure.
Overheating from improper flow or recirculation.
