Early detection of life-threatening arrhythmias such as ventricular fibrillation (VF) and rapid ventricular tachycardia (VT) is most essential for an automatic external defibrillator and remote cardiac patient monitoring. In this paper, we present a low-complexity, robust detection method for automatically detecting VT and VF events in the ECG signal. The proposed detection method consists of four...
This paper presents DrSEUs (Dynamic robust Single-Event Upset simulator), a novel fault injector that uses the Simics full-system simulator. Fault-injection testing enables the use of commercial off-the-shelf (COTS) processors in space, which are susceptible to radiation-induced faults but are desirable due to the lower cost and higher performance of COTS devices. The de facto standard for fault injection...
There is a growing interest to autonomously collect or manipulate objects in remote or unknown environments, such as mountains, gullies, bush-land, or rough terrain. There are several limitations of conventional methods using manned or remotely controlled aircraft. The capability of small Unmanned Aerial Vehicles (UAV) used in parallel with robotic manipulators could overcome some of these limitations...
The application of correlation filters for the task of facial landmark detection has been studied by many vision works. Their success, however, is limited by the presence of large pose variations, expression and occlusion in face images. Moreover, existing correlation filters may suffer from poor discrimination to distinguish visually similar landmarks such as the right and left eyes. In this work,...
This paper presents an approach to product development and reliability testing utilizing Robustness Validation (RV), an automotive electronics development recommended practice, specified in SAE-J1211 (surface vehicles) and SAE-J1879 (semiconductor devices in automotive applications). Intelligent testing and Robustness Validation approaches can become an integral part of the design for reliability...
The underground communications system is the lifeline of a mine. During a mine emergency, it plays a crucial role in rescue and recovery operations. However, the biggest challenge faced by conventional communications system is its own survivability. Therefore a robust, resilient communications platform plays a crucial role when the safety of the miners is concerned. Hence the motivations for this...
Individual face detection and identification technologies have improved greatly in terms of accuracy, but there exist challenges of adoption in Consumer Electronic devices due to the lack of large training databases pertaining to the individual. With 1 or 2 images to train about the current user, it is nearly impossible to identify a person's face robustly. So, in this paper we propose the use of...
The paper presents a novel technique to segment and extract streets from satellite images. This technique utilizes, for the first time in the known literature, the Maximally Stable Extremal Regions (MSER) algorithm to robustly identify and segment streets from satellite images. The technique extracts dark MSERs and then classifies them based on multiple metrics such as the intensity of the pixels,...
How do we evaluate automatically the optimal performance measurements of electronic circuitry? There are many new and interesting techniques for testing which crop up quite regularly. However, there must be a road map to better understand optimal performance of electronic circuitry. Optimal performance means the circuit is functioning at its' peak performance which means its' “Mean Time Between Failure”...
System level testing of industrial data processing software poses several challenges. Input data can be very large, even in the order of gigabytes, and with complex constraints that define when an input is valid. Generating the right input data to stress the system for robustness properties (e.g. to test how faulty data is handled) is hence very complex, tedious and error prone when done manually...
This paper, for the first time, introduces a multiple-class boosting scheme (MBS) to combine depth motion maps (DMMs) and completed local binary patterns (CLBP) for action recognition. DMMs derive from projecting depth frames onto three orthogonal Cartesian planes (front, side and top) and characterize the motion energy of an action, on which the CLBP features are further extracted. And then a new...
In general prospective, SI-SR or Single-Image Super-Resolution, which is one of the most useful algorithms of Super Resolution-Reconstruction (SRR) algorithms, is a mathematical procedure for acquiring a high-resolution image from only one coarse-resolution image, which is usually computed by Digital Image Processing (DIP). Even thought there have been substantially researched during the last decade,...
Specication guided falsication methods for hybrid systems have recently demonstrated their value in detecting design errors in models of safety critical systems. In specication guided falsication, the correctness problem, i.e., does the system satisfy the specication, is converted into an optimization problem where local negative minima indicate design errors. Due to the complexity of the resulting...
Dynamically substructured system (DSS) technique is increasing recognized in the testing field. A DSS method decomposes an entire system into several substructures, which are tested numerically or physically, but run as a whole like the original system. Thus, the advantages of DSS include flexibility, space-saving, and cost-reduction. In a DSS test, actuators produce unexpected disturbance, when transferring...
Development in electrical power transmission system requires the use of circuit breakers with increasing breaking capacity. To meet the test requirements of larger capacity of high voltage capacity, the parallel current injection synthetic testing is the most widely used method instead of direct testing, based on IEC 62271-100 and IEC 62271-101. During synthetic testing, the making switch is used...
A local tester for a code probabilistically views a small set of coordinates of a given word and based on this local view accepts code words with probability one while rejecting words far from the code with constant probability. A local tester for a code is said to be "robust" if the local views of the tester are far from acceptable views when the word being tested is far from the code....
We show a directed and robust analogue of a boolean isoperimetric type theorem of Talagrand. As an application, we give a monotonicity testing algorithm that makes, up to polylog factors, (square root of n)/ε2 non-adaptive queries to a function f:0, 1n -> 0, 1, always accepts a monotone function and rejects a function that is ε-far from being monotone with constant...
With recent advances in low-power low-cost communication, sensing, and actuation technologies, Medical Cyber Physical Systems (MCPS) have revolutionized automated medical diagnostics and care. With this revolution, dawns a new era of medical monitoring where fusing measurements from multiple devices provides unprecedented early detection of critical conditions. However, often explicit models and/or...
Two "heterogeneous" information dissemination networks were established on the basis of sets of actual "rum or information" and "anti-rum or information" dissemination data involving a real micro logging event. Through empirical analysis of degree centrality, between ness centrality and closeness centrality, it was discovered that all three centrality indexes of the two...
Batik cloth is Indonesia's national heritage. Across the archipelago, there are numerous patterns and motifs of batik, each having its own meaning and cultural significance. In this paper, we present the results of our investigation of various combinations of SIFT features moments used in automatic classification of batik motifs. The classification method used in this paper is the k-Nearest Neighbor...
