AI for Healthcare with Keras and Tensorflow 2.0
Learn how AI impacts the healthcare ecosystem through real-life case studies with TensorFlow 2.0 and other machine learning (ML) libraries.This book begins by explaining the dynamics of the healthcare market, including the role of stakeholders such as healthcare professionals, patients, and payers. Then it moves into the case studies. The case studies start with EHR data and how you can account for sub-populations using a multi-task setup when you are working on any downstream task. You also will try to predict ICD-9 codes using the same data. You will study transformer models. And you will be exposed to the challenges of applying modern ML techniques to highly sensitive data in healthcare using federated learning. You will look at semi-supervised approaches that are used in a low training data setting, a case very often observed in specialized domains such as healthcare. You will be introduced to applications of advanced topics such as the graph convolutional network and how you can develop and optimize image analysis pipelines when using 2D and 3D medical images. The concluding section shows you how to build and design a closed-domain Q&A system with paraphrasing, re-ranking, and strong QnA setup. And, lastly, after discussing how web and server technologies have come to make scaling and deploying easy, an ML app is deployed for the world to see with Docker using Flask.By the end of this book, you will have a clear understanding of how the healthcare system works and how to apply ML and deep learning tools and techniques to the healthcare industry.WHAT YOU WILL LEARN* Get complete, clear, and comprehensive coverage of algorithms and techniques related to case studies * Look at different problem areas within the healthcare industry and solve them in a code-first approach* Explore and understand advanced topics such as multi-task learning, transformers, and graph convolutional networks* Understand the industry and learn MLWHO THIS BOOK IS FORData scientists and software developers interested in machine learning and its application in the healthcare industryANSHIK has a deep passion for building and shipping data science solutions that create great business value.

Basics Interactive Design: User Experience Design
By putting people at the centre of interactive design, user experience (UX) techniques are now right at the heart of digital media design and development. As a designer, you need to create work that will impact positively on everyone who is exposed to it. Whether it's passive and immutable or interactive and dynamic, the success of your design will depend largely on how well the user experience is constructed.User Experience Design shows how researching and understanding users' expectations and motivations can help you develop effective, targeted designs. The authors explore the use of scenarios, personas and prototyping in idea development, and will help you get the most out of the latest tools and techniques to produce interactive designs that users will love.With practical projects to get you started, and stunning examples from some of today's most innovative studios, this is an essential introduction to modern UXD.
Clean C++20
Write maintainable, extensible, and durable software with modern C++. This book, updated for the recently released C++20 standard, is a must for every developer, software architect, or team leader who is interested in well-crafted C++ code, and thus also wants to save development costs. If you want to teach yourself about writing better C++ code, Clean C++20 is exactly what you need. It is written for C++ developers of all skill levels and shows by example how to write understandable, flexible, maintainable, and efficient C++ code. Even if you are a seasoned C++ developer, there are nuggets and data points in this book that you will find useful in your work.If you don't take care with your codebase, you can produce a large, messy, and unmaintainable beast in any programming language. However, C++ projects in particular are prone to get messy and tend to slip into a maintenance nightmare. There is lots of C++ code out there that looks as if it was written in the 1980s, completely ignoring principles and practices of well-written and modern C++.It seems that C++ developers have been forgotten by those who preach Software Craftsmanship and Clean Code principles. The web is full of C++ code examples that may be very fast and highly optimized, but whose developers have completely ignored elementary principles of good design and well-written code. This book will explain how to avoid this and how to get the most out of your C++ code. You'll find your coding becomes more efficient and, importantly, more fun.WHAT YOU WILL LEARN* Gain sound principles and rules for clean coding in C++* Carry out test-driven development (TDD)* Better modularize your C++ code base* Discover and apply C++ design patterns and idioms* Write C++ code in both object-oriented and functional programming stylesWHO THIS BOOK IS FORAny C++ developer or software engineer with an interest in producing better code.STEPHAN ROTH is a coach, consultant, and trainer for systems and software engineering with German consultancy company oose Innovative Informatik eG located in Hamburg.

Introduction to Python for Kids
Want to create cool games and apps to impress your friends (or yourself), but not sure where to start? Or, have you tried your hand at programming, but got utterly bored after combing through hundreds of pages of dry text? Then you’ve come to the right place! This book is the perfect blend of education and fun for kids 8 years and above looking to learn the magic of Python, one of the easiest and most powerful programming languages around, all while solving fun puzzles and building your own projects on the way.Yes, there’ll be chapters on the fundamentals of Python, such as variables, numbers, strings, automation with conditions, loops and functions, objects, and files. But, early on in the book you’ll get started with Turtle, a Python package that was custom-made for kids like you. It lets you literally draw and animate on your computer! Every concept will be interspersed with a fun mini project with Turtle, so you’ll never get bored. Once you get the fundamentals down, you’ll dive right into Tkinter and Pygame, more fun Python packages (goodbye theory!) and you’ll learn all about creating apps and games like the ones you see and use every day (bouncing ball, temperature converter, calculator, rock-paper-scissors, and so much more!).There are also four capstone projects at the end of the book that convert everything you’ve learned so far into full-blown apps and games that you can show off to your friends, parents, and even teachers! You’ll be creating a snake game with Turtle, a tic tac toe game with Tkinter, a full-fledged paint app, again with Tkinter, and finally, a classic space shooters game with Pygame (the cherry on top). Every project chapter will be accompanied with the logic behind the game/app and an explanation on how you’ve arrived at the logic. You’ll develop strong problem solving skills that’ll help you create future projects on your own.There are also two chapters dedicated to just creating fun mini projects and puzzles, one of them placed in the middle of the book to give you a welcome break from all the learning. The book ends with an overview on web development with Python and ideas for more fun projects and puzzles you can solve on your own. Become the “most likely to succeed” kid in your grade while having the most fun getting there!WHAT YOU'LL LEARN* Gain a gentle, but thorough introduction into the world of programming and Python* Create programs and solve problems with core Python concepts* Build mini projects and capstone projects (showcase worthy) with Turtle, Tkinter, and Pygame * Develop programming skills while doing the puzzles and activities described in the book WHO THIS BOOK IS FORKids 8 years and above.Aarthi Elumalai is a programmer, educator, entrepreneur, and innovator.

Introduction to Video Game Engine Development
Start your video game development journey by learning how to build a 2D game engine from scratch. Using Java (with NetBeans as your IDE and using Java’s graphics framework) or by following along in C# (with Visual Studio as your IDE and using the MonoGame framework), you’ll cover the design and implementation of a 2D game engine in detail. Each class will be reviewed with demonstration code. You’ll gain experience using the engine by building a game from the ground up.Introduction to Video Game Engine Development reviews the design and implementation of a 2D game engine in three parts. Part 1 covers the low-level API class by class. You’ll see how to abstract lower-level functionality and design a set of classes that interact seamlessly with each other. You’ll learn how to draw objects, play sounds, render text, and more. In Part 2, you’ll review the mid-level API that is responsible for drawing the game, loading resources, and managing user input. Lastly, in Part 3, you’ll build a game from the ground up following a step-by-step process using the 2D game engine you just reviewed.On completing this book, you’ll have a solid foundation in video game engine design and implementation.

Cybersecurity and Third-Party Risk
MOVE BEYOND THE CHECKLIST AND FULLY PROTECT YOURSELF FROM THIRD-PARTY CYBERSECURITY RISKOver the last decade, there have been hundreds of big-name organizations in every sector that have experienced a public breach due to a vendor. While the media tends to focus on high-profile breaches like those that hit Target in 2013 and Equifax in 2017, 2020 has ushered in a huge wave of cybersecurity attacks, a near 800% increase in cyberattack activity as millions of workers shifted to working remotely in the wake of a global pandemic.The 2020 SolarWinds supply-chain attack illustrates that lasting impact of this dramatic increase in cyberattacks. Using a technique known as Advanced Persistent Threat (APT), a sophisticated hacker leveraged APT to steal information from multiple organizations from Microsoft to the Department of Homeland Security not by attacking targets directly, but by attacking a trusted partner or vendor. In addition to exposing third-party risk vulnerabilities for other hackers to exploit, the damage from this one attack alone will continue for years, and there are no signs that cyber breaches are slowing.Cybersecurity and Third-Party Risk delivers proven, active, and predictive risk reduction strategies and tactics designed to keep you and your organization safe. Cybersecurity and IT expert and author Gregory Rasner shows you how to transform third-party risk from an exercise in checklist completion to a proactive and effective process of risk mitigation.* Understand the basics of third-party risk management* Conduct due diligence on third parties connected to your network* Keep your data and sensitive information current and reliable* Incorporate third-party data requirements for offshoring, fourth-party hosting, and data security arrangements into your vendor contracts* Learn valuable lessons from devasting breaches suffered by other companies like Home Depot, GM, and EquifaxThe time to talk cybersecurity with your data partners is now.Cybersecurity and Third-Party Risk is a must-read resource for business leaders and security professionals looking for a practical roadmap to avoiding the massive reputational and financial losses that come with third-party security breaches.GREGORY C. RASNER is the lead of Cyber Third-Party Risk at Truist Financial Corporation. He has extensive experience in cybersecurity and technology leadership in banking, biotech, software, telecom, and manufacturing. He is the author of several published articles on Third Party Risk and is a sought-after keynote speaker in this area.Foreword xviIntroduction xviiiSECTION 1 CYBERSECURITY THIRD-PARTY RISKCHAPTER 1 WHAT IS THE RISK?

Wireless and Mobile Hacking and Sniffing Techniques
Sniffing is the process of monitoring and capturing all the packets passing through a given network using sniffing tools. It is a form of tapping phone wires and get to know about the conversation. It is also called wiretapping applied to the computer networks.Phishing is a cybercrime in which a target or targets are contacted by email, telephone or text message by someone posing as a legitimate institution to lure individuals into providing sensitive data such as personally identifiable information, banking and credit card details, and passwords.There are several ways how hackers can gain access to a public WiFi network and infiltrate connected devices to steal data. The most common practice that hackers use is called sniffing. This method allows hackers to hijack any packet of data that is being transmitted between a device and a router.The mobile device has become an inseparable part of life today. The attackers are easily able to compromise the mobile network because of various vulnerabilities, the majority of the attacks are because of the untrusted apps. SMS is another way the attackers are gaining access to the mobile devices by sending phishing messages/spam messages to userThis report covers the main Wireless and Mobile Hacking and Sniffing Techniques.

Footprinting, Reconnaissance, Scanning and Enumeration Techniques of Computer Networks
Reconnaissance is a set of processes and techniques (Footprinting, Scanning & Enumeration) used to covertly discover and collect information about a target system. During reconnaissance, an ethical hacker attempts to gather as much information about a target system as possible.Footprinting refers to the process of collecting as much as information as possible about the target system to find ways to penetrate into the system. An Ethical hacker has to spend the majority of his time in profiling an organization, gathering information about the host, network and people related to the organization. Information such as ip address, Whois records, DNS information, an operating system used, employee email id, Phone numbers etc is collected.Network scanning is used to recognize available network services, discover and recognize any filtering systems in place, look at what operating systems are in use, and to protect the network from attacks. It can also be used to determine the overall health of the network.Enumeration is defined as the process of extracting user names, machine names, network resources, shares and services from a system. The gathered information is used to identify the vulnerabilities or weak points in system security and tries to exploit in the System gaining phase.The objective of the report is to explain to the user Footprinting, Reconnaissance, Scanning and Enumeration techniques and tools applied to computer networks The report contains of the following parts:Part A: Lab Setup Part B: Foot printing and ReconnaissancePart C: Scanning MethodologyPart D: EnumerationI am Dr. Hidaia Mahmoud Mohamed Alassouli.

Common Windows, Linux and Web Server Systems Hacking Techniques
A Trojan horse or Trojan is a type of malware that is often disguised as legitimate software. Trojans can be employed by cyber-thieves and hackers trying to gain access to users' systems. Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems. Once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system.A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus. Computer viruses generally require a host program.System hacking is defined as the compromise of computer systems and software to access the target computer and steal or misuse their sensitive information. Here the malicious hacker exploits the weaknesses in a computer system or network to gain unauthorized access to its data or take illegal advantage.Web content is generated in real time by a software application running at server-side. So hackers attack on the web server to steal credential information, passwords, and business information by using DoS (DDos) attacks, SYN flood, ping flood, port scan, sniffing attacks, and social engineering attacks.This report covers the common techniques and tools used for System, Windows, Linux and Web Server Hacking.

SPS-Programmierung mit dem Raspberry Pi und dem OpenPLC-Projekt
Einführung in die SPS-Programmierung mit dem Open-Source-Projekt auf dem Raspberry Pi und Modbus-Beispiele'mit dem'Arduino Uno und ESP8266Die SPS-Programmierung ist heute in der Industrie und in der Hausauto-mation sehr weit verbreitet. In diesem Buch beschreibt der Autor, wie der Raspberry Pi 4 als SPS eingesetzt werden kann. Angefangen mit der Softwareinstallation auf dem Raspberry Pi und dem SPS-Editor auf dem PC geht es nach einer Beschreibung der Hardware an das Programmieren.Es folgen interessante Beispiele nach IEC 61131-3 in den verschiedenen Programmiersprachen. Ausführlich wird auch erklärt, wie der SPS-Editor benutzt wird und wie die Programme auf den Raspberry Pi geladen und ausgeführt werden. Angefangen mit der Programmierung mit KOP (Kontaktplan) über ST (Structured Control Language) bis zu AS (Special Function Chart) werden alle IEC-Sprachen mit Beispielen behandelt. Diese können auf der Website des Autors heruntergeladen werden.Auch die Vernetzung kommt nicht zu kurz. Der Arduino Uno und der ESP8266 werden als ModbusRTU- bzw. ModbusTCP-Module program-miert, um ZugriŸ auf externe Peripherie zu erhalten. Damit ist es möglich, Sensoren einzulesen und Verbraucher zu schalten. Interessant dürften auch E/A-Schaltungen sein, die dem 24V-Industriestandard entsprechen.Befehlsübersichten für ST und KOP runden das Buch ab.Nach dem Durcharbeiten des Buches ist der Leser in der Lage, eigene SPS-Steuerungen mit dem Raspberry Pi zu verwirklichen.Josef Bernhardt hat sich schon früh mit Elektronik beschäftigt. Mit zwölf Jahren baute er seinen ersten Detektorempfänger. Die ersten Programmiererfahrungen sammelte er in den 80er-Jahren mit dem Commodore VC20. Auch Assemblerprogrammierung auf dem 8088-Prozessor ist ihm nicht fremd. Er kann auf über 30 Jahre Elektronikentwicklung an der Uni Regensburg zurückblicken. Dort war er im Bereich Elektronik- und Softwareentwicklung tätig. Mit der eigenen SMD-Fertigung setzt er auch Elektronikprojekte von Kunden um. Der Spaß an Elekt-ronik und Programmierung sowie sein Interesse an allem Neuen begleiten ihn schon sein ganzes Leben lang.
