Failure analysis on static condition (static leakage and standby current level) failed device would not cost long time to find root cause, but dynamic functional failure will. Failure analysis with dynamic strategy to localize a failure point is more significant in complicated function failed IC (Integrated Circuit). This paper would present an efficient strategy to locate the defect using dynamic...
Medical devices equipped with wireless connectivity and remote monitoring features are increasingly becoming connected to each other, to an outside programmer and even to the Internet. While Internet of Things technology enables health-care professionals to fine tune or modify medical device settings without invasive procedures, this also opens up large attack surfaces and introduces potential security...
Power MOSFET plays an important role in power electronic systems, the failure of which will lead to system losing functions. Thus the degradation failure process and mechanism of MOSFET attract wide attention of scholars. However current research works cannot solve the real time degradation monitoring problem of MOSFET. Normally, MOSFET should be removed from the system for testing or monitoring....

This paper presents a button-like wearable wireless non-contact system (NCMB-Button) for long-term multiple biopotential monitoring. Featured non-contact detection based on ultra-high input impedance of the analog front end, the NCMB-Button is capable of acquiring multiple biopotential signals including ECG, EMG, and EEG, through multiple layers of cloth without directly contacting human skin. The...
This article proposes an approach to generate test cases from BPMN models, for automated testing of Web applications implemented with the support of BPM suites. The work is primarily focused on functional testing and has the following objectives: (i) identify execution paths from the flow analysis in the BPMN model and (ii) generate the initial code of test scripts to be run on a given Web application...
In this paper, we present a new loT-based health monitoring approach in which collected medical sensor data is sent to an analysis module via low-cost, low-power and secure communication links provided by a LoRaWAN network infrastructure. We mainly focus on monitoring blood pressure, glucose and temperature in rural areas where cellular network coverage is either absent or does not allow data transmission...
Increasing the safety of a navigation lock, by creating a modern and efficient communication between the human operator and the machine, for a prompt and accurate information offered to the operator, about the status of the equipment it serves, it is a requirement of today navigation worldwide. This paper aims to describe the implementation of a modern and efficient centralized tracking equipment...
The state of art secure digital computing systems heavily rely on secure hardware as the Trusted Computing Base to build upon the chain of trust for trusted computing. Attack Protection Blocks are added to the hardware to prevent an adversary from bypassing the security provided by hardware using various side channel, voltage, frequency, temperature, and other attacks. However, attackers can target...
The dense instrumentation of future smart buildings enables the implementation of advanced control techniques which are aimed at the dual objectives of energy efficiency/cost savings and occupant comfort. One of the essential functions and prerequisite consists of robust dynamic occupancy detection and prediction which allows improved estimation of active thermal zones and internal loads, as compared...
LoRa, an emerging wireless technology, is examined for long range communication performance in a large area. Although LoRa shows good performance for long-distance transmission in the countryside, its radio signals can be attenuated and interfered with by buildings, trees and other signal sources. In urban areas, our observation shows that LoRa requires a dense deployment of LoRa gateways to ensure...
In recent years, the concept of the Internet of Things (IoT) has already been implemented in numerous application domains, such as smart city, intelligent healthcare assistant, and smart transportation management. Researchers or developers associated with these domains frequently require diverse types of IoT devices to implement or test their IoT related innovations. However, building an IoT-testbed...
In the Internet of Things (IoT) era, with ubiquitous remote sensing devices and other diverse data sources, nearly everything can forward voluminous data continuously, in real-time, which drives demand to perform real-time analytics on uninterrupted IoT data flows. The typical resultant approach is a cloud-centered architecture providing an analytic service for real-time IoT data processing. However,...
The abundance of activity trackers and biosignal sensors as well as the evolution of IoT and communication technologies have considerably advanced the concept of Quantified-Self. Nowadays there are several frameworks and applications that realize the concept, focusing though strictly on specific areas, from daily use to professional activities such as sport and healthcare. This work proposes a versatile,...
A device-based health conditions monitoring and diagnosis method for inverters is present. In the inverter, SiCGTO (Gate-Turn-Off Thyristor) is considered as the key device to achieve pulse-width modulation. So the performance degradation of SiC-GTO device induced by interface-states is critical for the health conditions of inverters. In the research, key electrical parameters, including the forward...
Internet of Things (IoT) services are increasingly deployed at the edge to access and control Things. The execution of such services needs to be monitored to provide information for security, service contract, and system operation management. Although different techniques have been proposed for deploying and executing IoT services in IoT gateways and edge servers, there is a lack of generic policy...
We describe a multi-layer security system called "Application Protected Execution" (APEx) that has an "In-VM monitoring" functionality protected by out-of-band memory created within a Virtual Machine (VM) on cloud-based nodes. The In-VM monitor functionality protects execution of security related software and is triggered by hooked system events to avoid context switched overhead...
