Survey on Error Control Coding TechniquesIJTET Journal
This document discusses various error control coding techniques used to ensure correct data transmission over noisy channels. It describes automatic repeat request and forward error correction as the two main approaches. Specific coding schemes covered include parity codes, Hamming codes, BCH codes, Reed-Solomon codes, LDPC codes, convolutional codes, and turbo codes. Reed-Solomon codes can correct multiple burst errors with high code rates. LDPC codes provide performance close to the Shannon limit with lower complexity than turbo codes. The document provides an overview of the coding techniques and their encoding and decoding processes.
This document summarizes and compares entropy and dictionary-based techniques for lossless data compression. It discusses how entropy coding like Huffman coding assigns shorter codes to more frequent symbols, making it well-suited for JPEG images. Dictionary techniques like LZW replace strings with codes, performing better on files with repetitive data like TIFFs. While entropy coding has simpler encoding, dictionary methods have better compression ratios and decoding capability. The document also presents the proposed Huffman coding of a bitmap image to assign variable-length codes based on color probabilities.
The document provides an overview of techniques for secure speech communication, including speech coding, speaker identification, and encryption/decryption. It discusses various speech coding techniques like waveform coding, parametric coding, and hybrid coding that can compress speech signals while maintaining quality. It also describes speaker identification methods using hashing to authenticate users. For encryption, it outlines symmetric techniques like AES that use a shared key, and asymmetric techniques like RSA that use public/private key pairs. The goal is to integrate these methods to provide a high level of security for speech communication by removing redundancy, authenticating speakers, and strongly encrypting signals.
Memory Based Hardware Efficient Implementation of FIR FiltersDr.SHANTHI K.G
The document summarizes memory-based hardware efficient implementations of finite impulse response (FIR) filters. FIR filters are commonly used in digital signal processing systems. The paper explores memory-based realization of FIR filters using techniques like direct memory implementation and distributed arithmetic. Direct memory implementation replaces multiplications with filter coefficients with pre-computed values stored in a read-only memory (ROM) or lookup table (LUT). Distributed arithmetic implements MAC operations using LUT accesses and shift-accumulation, making it well-suited for field-programmable gate arrays. The paper compares different memory-based architectures for FIR filters in terms of ROM size, delay, and throughput to assist in selecting the best architecture for a given application.

Combining cryptography with channel coding to reduce complicityIAEME Publication
This document summarizes a research paper that proposes combining cryptography and channel coding to increase security and reduce complexity. It describes how a linear feedback shift register can be used to generate a sequence to select different encoding matrices for different blocks of an input signal. This makes it difficult for intruders to decode the signal without knowing the key and matrix sequence. The encoding process multiplies each block with a selected matrix. Decoding detects and corrects errors using a parity check matrix and comparison to a reference array. Combining encryption and coding in this way could improve performance without increasing complexity.

IRJET-Block-Level Message Encryption for Secure Large File to Avoid De-Duplic...IRJET Journal
The document proposes a new Block-Level Message Encryption (BL-MLE) approach to achieve more efficient deduplication of encrypted large files in cloud storage. BL-MLE can achieve file-level and block-level deduplication, block key management, and proof of ownership simultaneously using a small set of metadata. It describes the BL-MLE method and how it uses AES, RSA, and SHA algorithms for encryption, authentication, and integrity checks. The experimental results show the upload of an encrypted document by the owner, user registration and access of the encrypted file using decryption keys, and the auditor performing integrity checks and generating audit reports.
A REAL-TIME H.264/AVC ENCODER&DECODER WITH VERTICAL MODE FOR INTRA FRAME AND ...csandit
The video coding standards are being developed to satisfy the requirements of applications for
various purposes, better picture quality, higher coding efficiency, and more error robustness.
The new international video coding standard H.264 /AVC aims at having significant
improvements in coding efficiency, and error robustness in comparison with the previous
standards such as MPEG-2, H261, H263,and H264. Video stream needs to be processed from
several steps in order to encode and decode the video such that it is compressed efficiently with
available limited resources of hardware and software. All advantages and disadvantages of
available algorithms should be known to implement a codec to accomplish final requirement.
The purpose of this project is to implement all basic building blocks of H.264 video encoder and
decoder. The significance of the project is the inclusion of all components required to encode
and decode a video in MatLab .
The document describes a lesson plan for a digital communication course at Matrusri Engineering College. The lesson plan covers linear block codes, including their description, generation, syndrome detection, minimum distance, error correction capabilities, and decoding using standard arrays and Hamming codes over 10 class periods. The objectives are to distinguish different error control coding techniques and their encoding/decoding algorithms. Textbooks and references are also listed.
The document discusses techniques for unlocking and searching handwritten document images. It describes paradigms like lexicon-driven optical character recognition (OCR) and lexicon-free OCR. It also discusses methods for fusing outputs from multiple recognizers and training combination functions. The document outlines challenges in handwriting recognition and search, and proposes approaches like topic categorization and lexicon reduction to enable search of historical handwritten archives.
This document proposes a new color-based cryptography method called Play Color Cipher (PCC) as an improvement over traditional substitution ciphers. PCC works by substituting characters, numbers, and symbols with color blocks, where each color is represented by RGB values. During encryption, the plaintext is divided into blocks and the ASCII value of each character is encoded into one of the RGB channels of the corresponding color block. With over 16 million possible color combinations, PCC aims to increase complexity for attackers compared to other ciphers. The document outlines the encryption and decryption algorithms and argues that PCC can help strengthen security against common attacks like brute force and known/chosen plaintext attacks by vastly increasing the search space.

This very short document contains a series of numbers and letters with no other context. It lists the characters "QU" followed by the numbers 1 through 9. No other meaning or purpose is evident from the limited information provided.
No document was provided to summarize. A summary requires source text to extract the key points and essential information from. Without a document, it is not possible to generate an accurate 3 sentence summary.
Emotional intelligence was first defined scientifically in 1990 by Mayer and Salovey, building on prior concepts. Goleman later proposed it involves five traits that determine one's EQ. Emotional intelligence involves self and social awareness and management. It is debated whether EQ can be accurately measured, though tests do exist to assess specific skills or provide an overall assessment. While EQ may help predict some life outcomes, it does not determine success on its own, and high IQ individuals like Einstein had low EQ without hindrance. EQ is significant for social and workplace interactions but is not a sole predictor of life outcomes and has limitations as a concept.
This document discusses databases and the evolution from flat files to relational databases. It covers:
1) The limitations of flat files including data duplication, separation of data across files, fixed queries, and proliferation of application programs.
2) The introduction of hierarchical and network databases to try to overcome limitations but these still led to inconsistent and redundant data.
3) An introduction to relational databases which overcome limitations by allowing each record to be of fixed length and each field to contain a single data item. This addresses issues with variable length records in previous approaches.
The document discusses the functions and purposes of translators in computing. It describes:
1) Interpreters and compilers translate programs from high-level languages to machine code. Compilers translate the entire program at once, while interpreters translate instructions one at a time as the program runs.
2) Translation from high-level languages to machine code involves multiple stages including lexical analysis, syntax analysis, code generation, and optimization.
3) Linkers and loaders are used to combine separately compiled modules into a complete executable program by resolving addresses and linking the modules together.
This document discusses common network environments, connectivity, and security issues. It describes how LANs and WANs are organized using different topologies and transmission mediums. It then explains key network components like switches, routers, bridges, and modems - how they connect different types of networks and segments. Finally, it discusses common network environments like the Internet, intranets, and extranets as well as technologies that enable them such as hypertext links, URLs, domain names, and HTML.
The operating system must manage hardware resources, provide an interface between users/software and hardware, and provide services like data security. It schedules programs to make best use of the processor when programs are performing input/output tasks. It uses interrupts to change the normal order of program execution in response to events like I/O device signals. Scheduling aims to maximize system usage, be fair to all programs, and prioritize more important programs when needed.
The document discusses computer architecture and the fetch-execute cycle. It describes the Von Neumann architecture, which uses a single processor that follows a linear sequence of fetching, decoding, and executing instructions. It then explains the fetch-execute cycle in more detail with the steps involved. Finally, it discusses parallel processor systems that can split up the fetching, decoding, and executing stages to improve efficiency.
The document discusses techniques for developing computer systems, including structured systems analysis and design method (SSADM) and data flow diagrams (DFDs). It provides details on the stages of SSADM and the symbols and steps used to develop DFDs. An example of a hotel reservation and payment system is presented as a DFD to illustrate the technique. Project management is also discussed, with an example of building a bungalow broken down into tasks, durations, and dependencies shown in a graph.
The document discusses different ways of representing numerical data in computing systems, including:
1) Binary representation, which converts decimal numbers to binary by repeatedly dividing by column headings and tracking the remainders as 1s and 0s.
2) Negative numbers can be represented using sign-and-magnitude or two's complement methods.
3) Other number systems like octal and hexadecimal are also discussed which use different column headings but the same representation principles.
4) Floating point representation separates a real number into a mantissa and exponent to store fractional numbers more efficiently in binary.
The document discusses how data and databases are valuable to organizations. It provides examples of how stock control systems and sales data can be used to automatically reorder stock. Banks also find customer data valuable for assessing loan risks. Modern communication allows sharing of data worldwide through value added network services and databases. Standards are needed for sharing data accurately between different systems. Computers now aid various forms of communication like voice mail, e-commerce, and video conferencing. The internet allows global communication and advertising. IT training must be continually updated as technology changes, which is altering many work patterns and jobs.
This document discusses different programming paradigms including procedural, object-oriented, and declarative paradigms. It provides examples of code using these paradigms. Specifically, it shows an assembly language program that adds two numbers, a C++ program that calculates the area of a rectangle, and Prolog queries to retrieve information from a database about people's genders and family relationships. It also discusses how parameters are used to pass values to functions in Visual Basic.
This document discusses real-time systems and simulation. It defines a real-time system as one that can react quickly enough to input data to affect the real world. Real-time applications include airline booking systems and nuclear reactor controls. Sensors measure physical quantities and transmit data to processors, while actuators accept signals from processors and initiate physical movements. Simulations allow computers to model real-world systems and scenarios through calculations, enabling testing without real-world risks or costs. Simulations have limitations in predicting truly random or complex human events. Parallel processing is needed for simulations involving vast data, complex relationships, and immense calculations.
This document is an exam for an Advanced Subsidiary Level computing exam. It contains 9 questions testing knowledge of topics like memory addressing, data structures, networks, and software development processes. The exam is 2 hours and contains multiple choice, short answer, and longer explanatory questions.

High performance Serverless Java on AWS- GoTo Amsterdam 2024Vadym Kazulkin
Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

This mark scheme is published as an aid to teachers and students, to indicate the
requirements of the examination. It shows the basis on which Examiners were initially
instructed to award marks. It does not indicate the details of the discussions that took place
at an Examiners’ meeting before marking began. Any substantial changes to the mark
scheme that arose from these discussions will be recorded in the published Report on the
Examination.
All Examiners are instructed that alternative correct answers and unexpected approaches in
candidates’ scripts must be given marks that fairly reflect the relevant knowledge and skills
demonstrated.
Mark schemes must be read in conjunction with the question papers and the Report on the
Examination.
• CIE will not enter into discussion or correspondence in connection with these mark
schemes.

Component 1 90 60 56 32
The thresholds (minimum marks) for Grades C and D are normally set by dividing the
mark range between the B and the E thresholds into three. For example, if the
difference between the B and the E threshold is 24 marks, the C threshold is set 8
marks below the B threshold and the D threshold is set another 8 marks down. If
dividing the interval by three results in a fraction of a mark, then the threshold is
normally rounded down.
