IoT-OAS: An OAuth-Based Authorization Service Architecture for Secure Services in IoT Scenarios

standardized way from third-party applications accessing online services, based on the representational state transfer (REST) web architecture. OAuth has been designed to provide an authorization layer, typically on top of a secure transport layer such as HTTPS. The Internet of Things (IoTs) refers to the interconnection of billions of resource-constrained devices, denoted as smart objects, […]

Microfluidically Tunable Microstrip Filters

A new approach for the development of tunable and reconfigurable microstrip (MS) devices is proposed. The basic idea consists of using a suspended substrate with an integrated network of plastic tubes, which can be selectively filled in with a high-permittivity dielectric fluid, e.g., water. The local change of the substrate effective permittivity achieved in such a way […]

FRoDO: Fraud Resilient Device for Off-line micropayments

Credit and debit card data theft is one of the earliest forms of cybercrime. Still, it is one of the most common nowadays. Attackers often aim at stealing such customer data by targeting the Point of Sale (for short, PoS) system, i.e. the point at which a retailer first acquires customer data. Modern PoS systems […]

A Sensorless Adaptive Maximum Power Point Extraction Method With Voltage Feedback Control for Small Wind Turbines in Off-Grid Applications

Due to the ever growing global energy demand and pollution levels, clean and renewable alternative energy resources, such as wind, have become indispensable for preserving the planet for future generations. With wind being an unpredictable resource, it is imperative that wind systems extract as much power from the wind as possible while it is available. […]

Glucose-tracking: A postprandial glucose prediction system for diabetic self-management

Up to today, there are around 400 million diabetics in the world. In China, there are more than 100 million diabetics. How to help them track and manage real-time glucose level is significant to control diabetic progression. As well known, the glucose level is directly related with food, while the conventional tracking glucose is depending […]

Heart murmur detection and classification using wavelet transform and Hilbert phase envelope

Detection and classification of heart murmurs play an important role in accurate diagnosis of different types of heart dysfunctions. In this paper, we present a noise-robust method for detection and classification of heart murmurs using stationary wavelet transform (SWT) and Hilbert phase envelope. The proposed method consists of five major stages: SWT based PCG signal […]

Disambiguating Stereoscopic Transparency Using a Thaumatrope Approach

Volume rendering is a popular visualization technique for scientific computing and medical imaging. By assigning proper transparency, it allows us to see more information inside the volume. However, because volume rendering projects complex 3D structures into the 2D domain, the resultant visualization often suffers from ambiguity and its spatial relationship could be difficult to recognize […]

Cumulative Distribution Function of Bivariate Gamma Distribution With Arbitrary Parameters and Applications

In this letter, we consider bivariate gamma distributions with arbitrary parameters and obtain closed-form expressions for the cumulative distribution function for scenarios where the difference between the shape parameters of the marginal distributions is an integer.

Balancing throughput and latency for an aerial robot over a wireless secure communication link

With the requirement for remote control of unmanned aerial vehicles (UAV) becoming more frequent in scenarios where the environment is inaccessible or hazardous to human beings (e.g. disaster recovery); remote functionality of a UAV is generally implemented over wireless networked control systems (WNCS). The nature of the wireless broadcast allows attackers to exploit security vulnerabilities through passive […]

High-pressure synthesis and superconductivity of the Yb-substituted Ba8−xYbxSi46 clathrates

Summary form only given. Clathrate materials are extended Si, Ge and Sn cage-like solids with sp3-hybridized networks. As a new generation of energy conversion materials, clathrates have received increasing attention over the past few years. Clathrates with an open network are tailorable materials containing polyhedral cages, which can capture alkali metal, alkaline-earth metal and europium atoms. These atoms […]
