Multi-modal classifier fusion with feature cooperation for glaucoma diagnosis

Background: Glaucoma is a major public health problem that can lead to an optic nerve lesion, requiring systematic screening in the population over 45 years of age. The diagnosis and classification of this disease have had a marked and excellent development in recent years, particularly in the machine learning domain. Multimodal data have been shown to be a significant aid to the machine learning domain, especially by its contribution to improving data driven decision-making. Method: Solving classification problems by combinations of classifiers has made it possible to increase the robustness as well as the classification reliability by using the complementarity that may exist between the classifiers. Complementarity is considered a key property of multimodality. A Convolutional Neural Network (CNN) works very well in pattern recognition and has been shown to exhibit superior performance, especially for image classification which can learn by themselves useful features from raw data. This article proposes a multimodal classification approach based on deep Convolutional Neural Network and Support Vector Machine (SVM) classifiers using multimodal data and multimodal feature for glaucoma diagnosis from retinal fundus images from RIM-ONE dataset. We make use of handcrafted feature descriptors such as the Gray Level Co-Occurrence Matrix, Central Moments and Hu Moments to co-operate with features automatically generated by the CNN in order to properly detect the optic nerve and consequently obtain a better classification rate, allowing a more reliable diagnosis of glaucoma. Results: The experimental results confirm that the combination of classifiers using the BWWV technique is better than learning classifiers separately. The proposed method provides a computerized diagnosis system for glaucoma disease with impressive results comparing them to the main related studies that allow us to continue in this research path

The DUNE Far Detector Interim Design Report, Volume 3: Dual-Phase Module

The DUNE IDR describes the proposed physics program and technical designs of the DUNE far detector modules in preparation for the full TDR to be published in 2019. It is intended as an intermediate milestone on the path to a full TDR, justifying the technical choices that flow down from the high-level physics goals through requirements at all levels of the Project. These design choices will enable the DUNE experiment to make the ground-breaking discoveries that will help to answer fundamental physics questions. Volume 3 describes the dual-phase module's subsystems, the technical coordination required for its design, construction, installation, and integration, and its organizational structure

Deep Underground Neutrino Experiment (DUNE), Far Detector Technical Design Report, Volume III: DUNE Far Detector Technical Coordination

The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay -- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume III of this TDR describes how the activities required to design, construct, fabricate, install, and commission the DUNE far detector modules are organized and managed. This volume details the organizational structures that will carry out and/or oversee the planned far detector activities safely, successfully, on time, and on budget. It presents overviews of the facilities, supporting infrastructure, and detectors for context, and it outlines the project-related functions and methodologies used by the DUNE technical coordination organization, focusing on the areas of integration engineering, technical reviews, quality assurance and control, and safety oversight. Because of its more advanced stage of development, functional examples presented in this volume focus primarily on the single-phase (SP) detector module

A Highly Reliable and Unbiased PUF Based on Differential OTP Memory

Physically unclonable functions (PUF) are essential for hardware identity and security for IoT devices. The PUF consists of amulti-bit string that requires unbiased randomness. A one-time programmable memory (OTPM) uses insulator breakdown inmetal-insulator-metaldevice to switch between insulating ("0") and conducting ("1") state. An OTPM based PUF produces an unbiased bit-string if exactly median breakdown voltage (V-BD) and time are used. The exact application of median V-BD is challenging in an integrated circuit as a conventional voltage supply tolerance specification is 10%. In this letter, we propose a differential OTPM-based PUF with a parallel circuit of two OTPM in series with a resistance. A high voltage stochastically produces a breakdown in one of the two OTPM first, which then reduces the voltage drop across the parallel OTPM circuit to prevent further breakdown events. The experimental results of differential OTPM PUF binary string generation show essentially unbiased randomness to demonstrate excellent resistance to supply voltage variation. Ideal uniqueness and reproducibility are observed. Thus, our approach enables PUF implementation with standard voltage supply tolerance and negligible post-processing

Physico-chemical Analysis of Ground Water a Review

Ground water is the main principal source for drinking water and other activities in Indapur taluka, Pune district, Maharashtra, India. Ground water is considered as pure form of water, with minute dissolved essentials and non essentials minerals in it. The only way pollution can contaminate ground water is through surface runoff, industrial effluent, runoff from agricultural site and also through river. Due to which the problem of ground water quality obtains high importance in the present day. The quality of ground water depends upon its physical and chemical properties. These properties are inter linked. Therefore interpretation of correlation coefficient between water quality parameters gives good idea about the quality of water. Various author conducted their studies on physical and chemical properties of ground water using co –relation and regression studies. This review attempts to highlight the main achievement in this area and Outline the advantages of co-relation and regression analysis in ground water quality
