Blockchain technology-presentation
This document outlines a seminar on blockchain technology. It begins with an introduction to blockchain as a growing list of linked data blocks that cannot be altered. It then discusses the history of bitcoin and how it relates to blockchain as an application of the technology. The working of the bitcoin ecosystem is explained as a public, decentralized network that builds consensus among participants through increasing security and participation. Key features of blockchain like immutability, transparency, and decentralization without intermediaries are also highlighted. Challenges like energy usage and scalability are noted.
Blockchain
A blockchain is, in the simplest of terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by any single entity. Each of these blocks of data (i.e. block) is secured and bound to each other using cryptographic principles (i.e. chain).
So, what is so special about it and why are we saying that it has industry-disrupting capabilities?
The blockchain network has no central authority — it is the very definition of a democratized system. Since it is a shared and immutable ledger, the information in it is open for anyone and everyone to see. Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.
Distributed systems and blockchain technology
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.
Blockchain Technology
Blockchain technology allows data to be stored and exchanged on a peer-to-peer network in a secure and decentralized manner without intermediaries. It works by validating transactions and adding them as blocks to an immutable blockchain that is shared across all nodes in the network. Blockchains use cryptography to ensure data integrity and prevent alteration of past records. Real-world applications of blockchain include powering cryptocurrencies like Bitcoin, implementing smart contracts, building decentralized applications, and developing government services like in Dubai.

MultiChain – Private multicurrency blockchain platform
An introduction to MultiChain, an open source platform for private blockchains, that is backwards compatible with Bitcoin Core.
Blockchain technology
Blockchain technology allows transaction records to be stored publicly and securely across a network of distributed nodes. Each transaction is authenticated through a digital signature and stored in a digital ledger that is shared across the network, making the data visible but not alterable. Blockchain became popular due to its ability to securely record transactions without the need for centralized authorities. It provides features like decentralization, enhanced security, distributed ledgers, and consensus that enable uses like secure medical data sharing, cross-border payments, supply chain monitoring and cryptocurrency exchanges. While powerful, it also faces challenges like scalability issues and high energy consumption.
Blockchain Technology
Blockchain technology provides a secure digital platform for recording and verifying transactions. It works by creating an immutable record, or "golden record", of transactions that is distributed across a network of computers. This makes altering logged data extremely difficult. Blockchain allows peer-to-peer transactions without intermediaries, reducing costs and settling transactions faster than traditional banking. It is decentralized, with data distributed across servers rather than a central hub, increasing security. Users and developers have more control over blockchains than with systems run by third parties.
5 Core Blockchain Technology Concepts
Today, blockchain technology doesn't need to be implemented. A word that once was foreign has now earned accolades from individuals across the globe. This technology is being talked about by every business and investor. Blockchain started its journey as an underlying Bitcoin exchange technology, and it has gained so much popularity over the years. Everyone speaks about Blockchain, from students to working professionals; but what makes Blockchain so attractive is that you need to know the concepts of Blockchain technology for this.

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
Blockchain is a decentralized database that maintains a continuously growing list of records called blocks. Each block contains transaction data and a link to the previous block. The first block is special as it has no preceding block. Blocks are linked through cryptography, forming a chain. Miners process transactions by solving complex math problems to find new blocks and receive rewards. The first application was Bitcoin, solving the double spending problem without a central authority. Other applications include Ethereum, Litecoin, Ripple, and SolarCoin. Key variables that impact the blockchain include block size, header size, and transaction size.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
