Due to process variations at the very low technology nodes, the manufactured chips are grouped into different speed bins. Currently, various types of maximum operation frequency (Fmax) tests are performed for efficient speed binning by applying complex functional or structural test patterns, which incurs high test cost. In this paper, a novel on-chip Binning Sensor is proposed which can monitor the...
IoT / Cloud / Big data / Mobile (ICBM) is a new technology paradigm that merges IoT, cloud, big data, and mobile technologies. In this study, we designed and implemented a smart farm environment management system that can collect and monitor information on crop growth utilizing ICBM technology. The wireless system proposed in this paper not only collects environmental data from the inside of a vast...
Low Power Wide Area Networks (LPWAN) are used in a number of applications, including disaster monitoring and recovery networks. LPWAN sensors capture data bits and transmit them via dedicated gateways, which are connected to public carrier networks (e.g., cellular networks). One of the challenges encountered in disaster management scenarios revolves around the carry/forward sensed data and geographical...
The trend towards the digitalization of our homes is motivated by the development of hardware and software platforms that have been researched in recent years. As in the Internet of Things, building a single, global platform that enables communication with a myriad of devices for home automation is virtually impossible. The platform proposed in this work deals, in isolation, with the problems in each...
In this paper, we report on a proof-of-concept wearable prototype, called iSeiz, that can detect specific seizure activity, namely generalized tonic-clonic, in epilepsy patients. We first describe the high-level architecture of iSeiz, and then elaborate on its hardware and software features, including its robust and low-computational intensive real-time seizure detection algorithm (SDA), as well as...
With the rapid advances in IoT technologies, the role of IoT gateways becomes even more important. Therefore, improving the reliability, availability and serviceability (RAS) of IoT gateways is crucial. Nowadays, Linux is widely adopted for core enterprise systems not only because it is a free operating system but also because it offers advantages in regards to operational stability. With many Linux...
A health monitoring method using the saturationregion resistance is proposed in this paper to identify the level of aging associated with power semiconductor switches inside a Boost converter. Power MOSFETs are one of the most age-affected components in power electronic converters, and the on-resistance has been proved to be the most significant aging factor in power MOSFETs. However, the small value...

From the last few years, Wireless body area networks (WBANs) have attracted a lot of attention from both academia and industry due to an increase in real-time data capturing and processing for patient monitoring. This has become possible due to the technological advancements in which high computing and communication facilities are available for most of the modern handheld devices. In this environment,...
A unidirectional security gateway is a network system in which data can travel in only one direction. Therefore, the system are used in protecting the safety and reliability of various critical infrastructures. Most of all, it has to be deployed with send and receive transceivers disconnected for one direction to ensure information security. In this paper, we introduce a unidirectional security gateway...

Non-invasive, environmental monitoring is being successfully utilised to improve health care outcomes for patients while allowing them to more safely and comfortably live in their homes instead of health care facilities. This promises to reduce costs and ease the health care burden for many countries globally. However, these systems are still in early stages of research and only highly skilled researchers...
This paper introduces a dead-time optimization technique for a 2-level voltage source converter (VSC) using turn-off transition monitoring. Dead-time in a VSC impacts power quality, reliability, and efficiency. Silicon carbide (SiC) based VSCs are more sensitive to dead-time from increased reverse conduction losses and turn-off time variability with operating conditions and load characteristics. An...
