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...
Intelligent connected sensor and actuator endpoint nodes enable the Internet-of-Things (IoT). A brief overview of endpoint node functional blocks and requirements for low-power consumption are discussed. VLSI technology enablers for IoT include Ultra low Power (ULP) and Ultra Low Leakage (ULL) semiconductor process platform extensions. ULP and ULL implementations for bulk silicon technologies are...
Nowadays, web service provisioning on mobile devices has become a high demand due to the improvement in mobile device capabilities and web service technologies. In this paper we present a RESTful-based framework for Mobile Web service migration and provisioning on both Android-based mobile devices and Java-based stationary devices in P2P wireless network. The proposed Web service migration framework...
Our homes, offices, and other spaces are expected to evolve into smart spaces served by devices having varying requirements and capabilities. To efficiently control and manage these devices, their controllers needs to be designed using the correct abstraction for the devices. In this paper, we present an abstraction for the devices in smart spaces, and we use this abstraction to present a 5D—deploy,...
In this paper, we introduce Kalis, a self-adapting, knowledge-driven expert Intrusion Detection System able to detect attacks in real time across a wide range of IoT systems. Kalis does not require changes to existing IoT software, can monitor a wide variety of protocols, has no performance impact on applications on IoT devices, and enables collaborative security scenarios. Kalis is the first comprehensive...

Privacy and authenticity of data pushed by or into wearable devices are of important concerns. Wearable devices equipped with various sensors can capture user's activity in fine-grained level. In this work, we investigate the possibility of using user's activity information to develop an implicit authentication approach for wearable devices. We design and implement a framework that does continuous...
It is crucial for cellular data network operators to understand the service quality perceived by its customers. The state-of-art systems deployed in cellular networks mostly report service quality aggregated on cell site level, which is typically an aggregation of tens or hundreds of customers depending on the locations of the cell sites. In this paper, we propose to enhance the measurement of customer-perceived...
Acknowledging the powerful sensors on wearables and smartphones enabling various applications to improve users' life styles and qualities (e.g., sleep monitoring and running rhythm tracking), this paper takes one step forward developing FitCoach, a virtual fitness coach leveraging users' wearable mobile devices (including wrist-worn wearables and arm-mounted smartphones) to assess dynamic postures...
Mobile devices are used for communication and for tasks that are sensitive and subject to tampering. Indeed, attacks can be performed on the users' devices without user awareness, this represents additional risk in mission critical scenarios, such as Public Protection and Disaster Relief (PPDR). Intrusion Detection Systems are important for scenarios where information leakage is of crucial importance,...
PerfMon is a prototype implementation of a real-time performance management method for sensor data communication in assisted living applications. It is implemented in accordance with the specification for GATT services in Bluetooth low energy (BLE). PerfMon provides a tool for real-time performance monitoring and control for caregivers and service providers. Test results from monitoring and control...
In this demo, we present a home network traffic monitoring platform. Our solution is based on two main software components using standard IPFIX flow export architecture: a probe and a collector. The probe role is to capture flows in progress and to perform real time traffic classification. We implemented the probe on an actual home gateway prototype showing its feasibility on hardware constrained...
Predictive maintenance of high voltage devices is a major issue for all power providers, due to costs and complexity. This article provides some theoretical and experimental principles which can be useful for all maintenance operations performed on high voltage switching devices and some simple methods applicable for assessing the status of all their contacts.

Quality of Service (QoS) is an important enabler for communication in industrial environments. The Arrowhead Framework was created to support local cloud functionalities for automation applications by means of a Service Oriented Architecture. To this aim, the framework offers a number of services that ease application development, among them the QoSSetup and the Monitor services, the first used to...
Batch process generally consists of multiple stages of operation. In view of such characteristic, multi-phase modeling and analysis help to improve monitoring performance and enhance understanding of the process. Although many partition algorithms have been put forward, these is no quantification index to evaluate the performance of phase model. Besides, the results may be affected by human factors...
The use of counterfeit smart grid devices throughout the smart grid communication infrastructure represents a real problem.

On Field calibration is increasingly considered as the best performing approach for air quality monitor devices. Field recorded sensor data together with co-located reference data build suitable dataset that are more representative of the complexity of real world conditions. However, many researchers pointed out the possible lack of generalization due to the strong dependence on the condition encountered...
The capability of counting targets (people or things) in a monitored area is important for emerging wireless applications. To this aim, passive systems that rely on signals of opportunity and device-free targets are preferred to active systems that rely on dedicated or personal devices for preserving privacy and reducing implementation costs. This paper develops a framework for design and analysis...
Accelerometer sensors are ubiquitously available in consumer electronics such as smart phones and wearables.
