Real-time tracking is an important problem in computer vision in which most methods are based on the conventional cameras. Neuromorphic vision is a concept defined by incorporating neuromorphic vision sensors such as silicon retinas in vision processing system. With the development of the silicon technology, asynchronous event-based silicon retinas that mimic neuro-biological architectures has been...
Coverage and connectivity are two important performance evaluation indices for wireless sensor network (WSNs). In this paper, we focus on the connected target k-coverage (CTCk) problem in heterogeneous wireless sensor networks (HWSNs). A distributed connected target k-coverage algorithm (DCTCk) is proposed in order to generate connected cover sets for energy efficient connectivity and coverage maintenance...
Most of the MEMS inertial switches developed in recent years are intended for shock and impact sensing above 40 g. These switches are fabricated based on non-silicon surface micromachining with multiple steps of electroplating. In this paper, a silicon based low-g inertial switch typically used for linear acceleration sensing is designed and fabricated. The inertial switch consists of a high volume...
Gate-coupled reflectometric spectrometry has recently emerged as a tool for studies of transport in nanostructures. Here we report reflectometric spectroscopy of a double-gate single electron device in which two coupled quantum dots are formed under the gates. The spectroscopy is performed by detection of charging processes in the system using a dual port reflectometer. The potential application of...
Modern sensors that are increasingly flexible may be used to schedule various functions. Such sensors typically have competing demands on limited sensor resources such as the sensor timeline. Sensor management systems attempt to meet the overall goal of the sensor user by considering the user's priorities and the capabilities of the sensor. This paper describes an algorithm for scheduling an electronically...
It is important to verify the potential of assistive technology like smart walkers and their long-term effects in rehabilitation therapies. Thus, this study introduced a smart walker in the rehabilitation of an ataxic patient during 3 weeks. His gait pattern and postural stability was acquired and evaluated. Great improvements in gait parameters as well as in postural stability were observed.
In view of the existing community network division algorithm without considering the weight and direction of the edge, we propose a novel algorithm in Pervasive Sensing Environment. Based on the node optimal path, the algorithm calculates the optimal path tree of mobile nodes, similarity index and community dispersion index and so on parameters to realize the reasonable division for directed weighted...
We focus on considering noise properties in hyperspectral images acquired by different sensors. An initial assumption is that signal-dependent and signal-independent components are present. Using modern methods of blind estimation of noise parameters from images at hand, contributions of signal-dependent and signal-independent noise components are evaluated and compared for real-life images. It is...
Internet of Things regroups numerous applications. Among those, a common critical point is definitely power, as well as energy efficiency. 28nm UTBB FDSOI (28FDSOI) has demonstrated its superiority in terms of energy efficiency through numerous publications. This paper demonstrates the extra mile 28FDSOI is able to offer to designers, enabling on one hand ultra-low power (ULP) system-on-chips for...
This study proposes a 7T1R nonvolatile SRAM (nvSRAM) to 1) reduce store energy by using a single NVM device, 2) suppress DC-short current during restore operations through the use of a pulsed-overwrite (POW) scheme, and 3) achieves high restore yield by using a differentially supplied initialization (DSI) scheme. This initialization-and-overwrite (IOW) 7T1R nvSRAM improves breakeven-time (BET) by...

The microfabrication technology has had a chequered history of over 50 years in the field of microelectronics. Aggressive miniaturization of microelectronic devices has resulted in faster logic circuits; & and it has also reduced their power requirements. MOSFET device dimensions have already entered the sub-100 nanometer regime. The same successful principles of microfabrication were applied...

Volunteered Service Composition (VSC) refers to the process of composing volunteered services and resources. These services are typically published to a pool of voluntary resources. Selection and composition decisions tend to encounter numerous uncertainties: service consumers and applications have little control of these services and tend to be uncertain about their level of support for the desired...
This paper presents our recent work towards state-of-the-art integrated test concepts for the in-situ characterization of silicon-integrated millimeter-wave devices and transceiver components for radar and communication applications. Narrowband as well as ultra-broadband integrated network analysis solutions for a variety of frequency bands ranging from 50 to 120 GHz are outlined. In this context,...
A laser bonding technique has been developed recently to create an innovative material based on a silicon/diamond interface. In this work, we propose the development and the application of a numerical model for TCAD simulations of poly-crystalline diamond conceived for Silicon-on-Diamond (SoD) sensors to be used, e.g., as particle detectors in High Energy Physics (HEP) experiments. The model is based...
Molecular communication between biological entities is a new paradigm in which biological nodes sense the environment, communicate and cooperate with each other. Ligand receptors are among the most common mechanisms used by biological entities such as bacteria to sense the molecular signals in their surroundings. In such a mechanism, molecules (i.e., ligands) bind to certain proteins (i.e., receptors)...
This paper presents a confidence-aware maximum likelihood estimation framework to solve the truth estimation problem in social sensing applications. Social sensing has emerged as a new paradigm of data collection, where a group of individuals volunteer (or are recruited) to share certain observations or measurements about the physical world. A key challenge in social sensing applications lies in ascertaining...
This paper presents a spatial-temporal aware analytical framework to solve the truth finding problem in social sensing applications. Social sensing has emerged as a new big data application paradigm of collecting observations about the physical environment from social sensors (e.g., humans) or devices on their behalf. The collected observations may be true or false, and hence are viewed as binary...
The paper introduces a new reusable asynchronous component, called Opportunistic Merge element, that merges two or more request-acknowledgement channels into one and is allowed to opportunistically bundle requests from different input channels if they arrive sufficiently close to each other. We present a speed-independent implementation of this component and verify some of its correctness properties...
