The document proposes new techniques called ERASE and ERASERS for more efficiently sanitizing computer media. ERASE calculates the entropy of disk blocks and overwrites those within a sensitive entropy range. ERASERS divides the area to be wiped into subpopulations, randomly samples blocks within each, and only overwrites subpopulations containing sensitive data. The techniques were implemented in a tool and showed improvements over current methods for wiping drives of increasing size.
The document summarizes Philips' SmartPath to dStream program, which upgrades existing MRI systems to digital broadband architecture without requiring a new magnet. It transforms systems into digital MRI with benefits like improved image quality, speed, and expandability. The program overhauls key system components, extends the lifetime by 10 years, and has lower costs than a new installation while achieving similar performance to the latest systems. It also has environmental benefits from reusing the existing magnet.
The document describes a multiprogramming system with a hierarchical structure implemented on a Dutch computer. The system divides all activities across sequential processes at different hierarchical levels, with independent abstractions at each level. This hierarchical structure proved vital for verifying the system's logical soundness and implementation correctness. The primary goal of the system is to smoothly process a continuous flow of user programs as a service to the university.
Recent observed environmental changes as well as projections in the fourth assessment report of the Intergovernmental Panel on Climate Change shed light on likely dramatic consequences of a changing mountain cryosphere following climate change. Some very destructive geological processes are triggered or intensified, influencing the stability of slopes and possibly inducing landslides. Unfortunately, the interaction between these complex processes is poorly understood. This project addresses the key issues in response to such changing conditons: monitoring and warning systems for the spatial and temporal detection of newly forming hazards, as well as extending the quantitative understanding of these changing natural systems and our predictive capabilities.
The Philips CT SyncRight option provides seamless integration between CT scanners and compatible injectors, allowing communication of scanning and injection parameters. SyncRight simplifies clinical workflow by streamlining operations and reducing decision points by over 60%, allowing clinicians to focus more on patients. Key benefits include automatically loading injection protocols, modifying protocols through the scanner interface, viewing injection progress in real-time, and producing reports.
The document proposes a trigger identification service to defend against reactive jammers in wireless sensor networks. The service aims to efficiently identify all sensor nodes whose transmissions trigger jamming attacks, known as trigger nodes. This is achieved through a group testing process using a randomized error-tolerant nonadaptive group testing scheme. The identification of trigger nodes can then be used to exclude them from routing paths and help locate reactive jammers. The paper presents models for the sensor network, jammer behaviors, and analyzes the performance of the proposed identification service.
The document summarizes Senso LAB, one of the most advanced wireless sensor network labs hosting hundreds of heterogeneous sensor nodes deployed around Middlesex University. It has over 20 members including professors and researchers studying topics such as energy-aware performance evaluation of wireless sensor networks, unequal clustering algorithms, intrusion detection systems, software modeling frameworks, and presents ongoing and future work.

NOISE REMOVAL TECHNIQUES FOR MICROWAVE REMOTE SENSING RADAR DATA AND ITS EVAL...cscpconf
Microwave Remote Sensing data acquired by a RADAR sensor such as SAR(Synthetic Aperture Radar) is affected by a peculiar kind of noise called speckle. This noise not only renders the
data ineffective for classification, texture analysis, segmentation etc. which are used for image analysis purposes, but also degrades the overall contrast and radiometric quality of the image. Here we discuss the various noise removal techniques which have been widely used by scientists all over the world. Different filtering methods have their pros and cons, and no single method can give the most satisfactory result. In order to circumvent those issues, better and better methods are being attempted. One of the recent methods is that based on Wavelet technique. This paper discusses the denoising techniques based on Wavelets and the results from some of those methods. The relative merits and demerits of the filters and their evaluation is also done.

Both images have sufficient contrast and density to evaluate for fractures or injuries while minimizing radiation exposure to the patient.
This document provides an overview of dental radiography and x-ray physics. It defines key terms like atomic structure, ionization, and electromagnetic radiation. X-rays are produced when electrons collide with a tungsten target in the dental x-ray tube. The tubehead contains the x-ray tube, filters, and collimator to shape the beam. X-rays can interact with matter through absorption, Compton scattering, or coherent scattering. The document also outlines the parts of the x-ray machine and how alternating current is converted to produce x-rays when the exposure button is engaged.
This document provides information on periapical radiography. It discusses the history and types of dental x-rays, including periapical radiographs. Periapical radiographs are used to detect abnormalities of the root structure and surrounding bone. The document outlines techniques for proper positioning during periapical radiography, including the paralleling technique and bisected angle technique. It also discusses advantages and disadvantages of each technique as well as indications for periapical radiography.
Panoramic radiography, also called a panoramic x-ray, captures a single image of the entire mouth, including teeth, jaws, and surrounding structures. It is commonly used by dentists and oral surgeons to evaluate bones, teeth, and check for issues like tumors, cysts, or impacted teeth. The procedure involves a rotating x-ray tube that projects a beam through the patient's head and onto a rotating film or detector. It is painless, fast, and provides a wider view than intraoral x-rays. While it does not show the same detail as other imaging tests, panoramic x-rays are useful for initial evaluation of dental problems.
Computed radiography and direct/digital radiography are two digital imaging techniques. Computed radiography uses an imaging plate that captures x-ray data, which is then converted to a digital image. Direct digital radiography uses detectors like TFT or flat panel detectors to directly capture x-ray data digitally. Both techniques offer benefits over traditional film like faster imaging and easier sharing of images.
The document summarizes key aspects of radiographic film, including its composition, construction, types, handling, and the latent image formation process. Radiographic film consists of a base and emulsion layer containing light-sensitive silver halide crystals. X-rays interact with the crystals to form a latent image, which is developed into a visible image. Proper handling and storage of the film is required to avoid artifacts and ensure optimal image quality.
The document discusses different types of radiography technologies, including computed radiography (CR), direct digital radiography (DR), and the components and layers of imaging plates (IPs) used in CR. It also covers image processing techniques for CR/DR such as histogram generation, exposure compensation, and potential artifacts that can occur during acquisition, post-acquisition or display.
The document discusses various radiographic exposure factors and how they influence the quantity and quality of x-radiation exposure to patients. It describes how factors like kVp, mA, and exposure time determine the radiation dose and beam quality. It also discusses how the design of the x-ray machine like focal spot size, filtration, and high voltage generation impact technical settings. Film factors like sensitometry, contrast, and processing also influence radiographic image quality.

This document discusses cognitive radio networks (CR). CR networks are defined as networks that are aware of their surroundings and can dynamically reconfigure their characteristics. The document outlines topics that will be discussed including CR antennas, mechanisms, accessibility, adaptivity, scalability, reliability and interconnectivity. It provides examples of how CR networks improve these qualities and can sense spectrum usage, analyze it, decide on parameters, and tune transmissions accordingly using reconfigurable antennas. The document compares CRs to conventional radios and outlines benefits of CRs such as functioning in challenging conditions and identifying unused spectrum. It mentions xG Technology developed CR network technology called xMax.
Cognitive radio is a form of wireless communication that detects available channels in the radio spectrum and moves into vacant channels to avoid occupied ones. It senses its operational environment to detect unused spectrum and adjusts transmission parameters accordingly. This allows for more efficient use of the spectrum by taking advantage of spectrum white spaces. The cognitive cycle involves spectrum sensing, decision, sharing, and mobility. Cognitive radio networks apply these principles across network resources as well to optimize performance. Techniques like software-defined radio, machine learning, game theory, and cross-layer design help enable cognitive capabilities. Cognitive radio could help address increasing mobile data usage and be applied in 5G networks and new applications.
The document discusses security risks associated with connecting smart meters and other devices to electricity networks. It notes that electricity networks are highly regulated due to safety concerns, but adding internet-connected devices introduces new cybersecurity risks. Specifically, the document outlines how wireless protocols used by smart meters could allow malware and denial of service attacks to spread and potentially interfere with network operations. It argues more testing is needed to ensure the security of smart meter networks before widespread deployment.
Electricity networks are highly regulated due to safety concerns. Previously, errors in control systems did not require immediate fixes unless they posed an operational threat. However, smart meters add wireless connections, potentially allowing cyber threats from the internet to impact infrastructure. Many smart meters and their wireless protocols have vulnerabilities. Extensive security testing is needed given that attacks have had serious consequences for other critical infrastructure networks.
