11.quadrature radon transform for smoother tomographic reconstruction
This document discusses a technique called quadrature Radon transform for tomographic reconstruction. The quadrature Radon transform uses projections from two angles (θ and θ+π/2) rather than just one angle as in conventional Radon transform. This provides additional information that can yield smoother reconstructions. Two approaches are proposed - treating the two sets of projections as real and imaginary parts of a complex number, or averaging the individual back projections. Experimental results show the quadrature Radon transform produces numerically and visually better reconstructions compared to using projections from a single angle.

Dimension Reduction Introduction & PCA.pptx
PCA is a dimensionality reduction technique that uses linear transformations to project high-dimensional data onto a lower-dimensional space while retaining as much information as possible. It works by identifying patterns in data and expressing the data in such a way as to highlight their similarities and differences. Specifically, PCA uses linear combinations of the original variables to extract the most important patterns from the data in the form of principal components. The first principal component accounts for as much of the variability in the data as possible, and each succeeding component accounts for as much of the remaining variability as possible.

Introduction to Apache Ant
This document provides an introduction to Apache Ant, a build tool for Java projects. It begins by explaining why Ant is important to learn despite IDEs having their own build systems. The document then outlines what Ant is and how it can be used for automation beyond just building. It provides a basic example of creating an "Hello World" project in Ant and comparing it to doing so manually in Java. The document dives deeper into Ant programming concepts like targets, properties, tasks and extending Ant functionality. It aims to give an overview of Ant and how it can be used for Java project builds.
Introduction to GNU Make Programming Language
The document discusses the GNU Make programming language. It describes Make as having 3 main components: file dependencies that determine which rules to evaluate based on pattern matching; shell commands encapsulated in rules to execute if a target is out of date; and string processing functions for manipulating Make variables. The document provides examples of basic Makefiles and explains key concepts like rules, variables, automatic variables, and how Make uses a functional programming paradigm.
Ch6 file, saving states, and preferences
This document discusses various techniques for persisting application data in Android, including:
1. SharedPreferences which allow storing key-value pairs that can be shared within an app but not between apps.
2. Saving activity instance state by overriding onSaveInstanceState() which is called when an activity may be destroyed.
3. Preference frameworks for creating settings screens using XML preference hierarchies and listeners for updates.
4. Reading and writing files using openFileInput() and openFileOutput() which are restricted to the app's directory.
5. Including static resource files in the res/raw folder to bundle with the app.
[C++ gui programming with qt4] chap9
This document provides code examples for enabling drag and drop functionality in Qt applications. It demonstrates how to allow dragging files onto a window, initiate dragging from a QListWidget, and add drag and drop to a QTableWidget. It also discusses subclassing QMimeData to support custom drag data types and handling the clipboard by subclassing QMimeData and setting it on the clipboard.
Ch5 intent broadcast receivers adapters and internet
The document provides an overview of intents, broadcast receivers, adapters, and using internet resources in Android applications. It discusses how intents allow interaction between applications through message passing and how they can be used to start activities, broadcast events, and start services. It covers explicit and implicit intents, returning results from activities, and registering broadcast receivers and activities to handle intents through intent filters. The document also discusses linkify for making links in text views, broadcasting events with intents, and registering broadcast receivers in the manifest.
Ch4 creating user interfaces
This document discusses creating user interfaces for Android applications. It introduces views, layouts, activities and terminology used in Android UI development. It covers creating activities with views, inflating layouts, optimizing layouts, creating new views by modifying existing views or creating custom views. The document also discusses drawable resources, resolution independence, and creating and using menus in Android.
Ch3 creating application and activities
This document provides an overview of how to structure Android applications and work with resources. It discusses the main building blocks of an Android application including activities, services, intents, content providers, broadcast receivers, and widgets. It also covers the application manifest file, application lifecycles and priority levels. Additionally, it explains how to externalize and access resources through the R class and resource getter methods.
Function pointer
This document discusses function pointers, callback functions, functors, and the observer pattern in C and C++. It begins by explaining the syntax of function pointers and how they can point to the address of a function. It then discusses how callback functions allow a caller function to pass a function pointer as an argument, uncoupling the caller from the callee. Functors are described as functions with state that can act like functions through operator overloading. The observer pattern is explained as defining dependencies between objects so that one object (the subject) notifies observer objects of any state changes.
Git basic
This document provides an introduction and overview of Git, including:
1. An overview of centralized (CVCS) and distributed (DVCS) version control systems and how Git is a DVCS that uses snapshots, not differences.
2. Instructions on installing Git and setting user configuration.
3. Descriptions of basic Git commands like init, add, commit, tag, log, clone, branch, checkout.
4. An explanation of how to set up a Git repository in Dropbox for cloud backup and collaboration.
Project Hosting by Google
This document discusses how to download and host open source projects using TortoiseSVN and Google Code. It provides instructions on how to download other developers' projects from Google Code using TortoiseSVN checkout and how to host your own projects on Google Code by creating a local working directory, adding and committing files.
An Introduction to Hidden Markov Model
This document provides an introduction to Hidden Markov Models (HMMs). It begins by explaining the key differences between Markov Models and HMMs, noting that in HMMs the states are hidden and can only be indirectly observed through observations. It then outlines the main elements of an HMM - the number of states, observations, state transition probabilities, observation probabilities, and initial state distribution. An example HMM is provided. Finally, it briefly introduces three common problems in HMMs - determining the most likely model given observations, determining the most likely state sequence, and determining the model parameters that are most likely to have generated the observations.
