Genre: Science

A response to increasingly stringent regulation of pollution and toxicity levels in industrial waste discharge, Micellar Enhanced Ultrafiltration: Fundamentals & Applications offers the most complete book available on the benefits and use of micellar-enhanced ultrafiltration (MEUF) to achieve continuous removal of organic and inorganic pollutants. An Unparalleled Book That Addresses Both Academic and Industrial Points of View Several membrane-based techniques, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, are currently used in a wide range of applications throughout the textile, pulp and paper, sugar, chemical, pharmaceutical, biomedical, biotechnological, and food industries. However, although reverse osmosis is an effective means of removing contaminants, this book explains why MEUF is a better substitute, as it less expensive, less energy-intensive, and more efficient and practical for a wider range of applications. Topics covered include: Effects of pollution in water and its consequences Various treatment processes and membrane technologies Fundamentals of ultrafiltration Outline of various membrane modules and modeling approaches Principles of colloid chemistry Theories of micelle formation Stability and dynamics of micelles Phenomena of counterion binding Solubilization of organic pollutants Selection criteria for surfactants Various flux enhancement techniques Recovery of precious metals This book conveys how, with proper selection of surfactant and membrane, MEUF can be used to efficiently remove almost all metal ions (heavy metals, lanthanides, radioactive materials, etc.) with reasonably high efficiency and throughput. It also details the MEUF process for removal of inorganic (cations, anions, and their mixture) and organic pollutants. The authors explain how the economy of the overall process makes recovery and reuse of surfactants essential, and they address various influencing factors on the increase in throughput and the resulting operating problems. Elaborating on technologies involving precipitation and other methods, they also illustrate additional potential applications for MEUF technology.

Link Prediction in Social Networks

Author: Virinchi Srinivas
Publisher: Springer
ISBN: 9783319289229
Release Date: 2016-01-22
Genre: Computers

This work presents link prediction similarity measures for social networks that exploit the degree distribution of the networks. In the context of link prediction in dense networks, the text proposes similarity measures based on Markov inequality degree thresholding (MIDTs), which only consider nodes whose degree is above a threshold for a possible link. Also presented are similarity measures based on cliques (CNC, AAC, RAC), which assign extra weight between nodes sharing a greater number of cliques. Additionally, a locally adaptive (LA) similarity measure is proposed that assigns different weights to common nodes based on the degree distribution of the local neighborhood and the degree distribution of the network. In the context of link prediction in dense networks, the text introduces a novel two-phase framework that adds edges to the sparse graph to forma boost graph.

Part 1 Multimedia Evidence Handling includes a discussion on the terminology, real-world requirements, standards, legal aspects and technical challenges regarding multimedia evidence which concern forensics examiners and practitioners in law enforcement and digital forensics/e-discovery industry. It will highlight key differences between computer forensics and multimedia forensics, and the new technical challenges raised from such differences. Part 2 Digital Evidence Extraction bridges digital forensics and multimedia forensics by focusing on extraction of two classes of evidence: 1) non-multimedia evidence that can be extracted from multimedia data via a multimedia processing and analysis process, 2) multimedia evidence that are extracted or enhanced via non-multimedia forensic approaches (e.g. by using traditional computer forensic techniques and tools). Part 3 Multimedia Device and Source Forensics focuses on two main topics: digital forensics of multimedia devices and multimedia source identification. The first topic covers available techniques and tools of analysing multimedia devices to recover different types of evidence, and the second topic is about determining the source of a multimedia artefact (a digital or printed multimedia document). Multimedia devices covered include digital cameras/camcorders, audio recorders and players, scanners, printers. Part 4 Multimedia Content Forensics focuses on forensic analysis and identification of multimedia data which is a core area in the multimedia forensic field. Chapters in this part are about pure digital data, but many techniques are based on physical mechanisms that are involved in the generation of the digital data. Some techniques are also based on multimedia device/source identification from the third part, e.g. image forgery may be detected by exposing clues about mismatch of detected sources of different regions of the same image.

Hacking Happiness

Publisher: TarcherPerigee
ISBN: 9780399173196
Release Date: 2015-03-10
Genre: Self-Help

In Hacking H(app)iness, futurist and contributing Mashable writer John C. Havens introduces you to your 'quantified self' - your digital identity represented by gigabytes of data produced from tracking your activities on your smartphone and computer. Harvens argues that megacorporations such as Google, Facebook, and Amazon gather this data because of its immense economic value, encouraging a culture of 'sharing' while simultaneously hoarding information based on our lives, for private monetary gain. While Edward Snowden's revelations exposed the depths of government surveillance on our private affairs, Hacking H(app)inesspoints out the dangers of losing our digital identities to the highest bidder. But there's an alternative to this digital dystopia. Emerging technologies will help us reclaim this valuable data for ourselves, so we can directly profit from the insights linked to our quantified selves. At the same time, sensors in smartphones and wearable devices will help us track our emotions to improve our well-being, using the science of positive psychology. Havens proposes that these trends will lead to new economic policies that redefine the meaning of 'wealth,' allowing governments to create policy focused on purpose rather than productivity. An issues book highlighting the benefits of an examined life in the digital world, this timely work illustrates how controlling and utilizing insights from our personal data can result in a happier humanity.
