Mixed-criticality systems are real-time systems that combine both safety-critical and non-critical applications. These systems have been gaining interest due to their practical applications and their adoption in standards in several domains. On the other hand, it is often overlooked in the research on mixed-criticality systems that these systems are still safety critical and must be able to operate...
This paper presents a new multiphase-multilevel inverter configuration for open-winding loads and suitable for medium power (low-voltage/high-current) applications such as ‘More Electric Aircraft’. Modular structure comprised of standard dual three-phase voltage source inverter (VSI) along with one additional bi-directional semi-conductor device (MOSFET/IGBT) per phase and two capacitors with neutral...
Industrial low-power wireless mesh standards, suchas IEEE802.15.4-TSCH, WirelessHART and ISA100.10a, offerwire-like end-to-end reliability and a decade of battery lifetime. These technologies have become de-facto standards, used inthe most demanding applications such as industrial processmonitoring. In this paper, we explore what it takes to go fromindustrial process monitoring to industrial process...
The forthcoming fifth generation of cellular networks (5G) is envisioned to support massive machine type communication (MTC) where a vast number of MTC devices utilize the wireless spectrum to create what is called Internet-of-Things. The vision calls for a paradigm shift in the design and operation of wireless access schemes to enable efficient and reliable massive connectivity with many channel...
In this paper, the problem of securely computing a function over the binary modulo-2 adder multiple-access wiretap channel is considered. The problem involves a legitimate receiver that wishes to reliably and efficiently compute a function of distributed binary sources while an eavesdropper has to be kept ignorant of them. In order to characterize the corresponding fundamental limit, the notion of...
Physically unclonable functions (PUFs) serve as untamperable secrets buried in a device thatmust meet some properties in order to be securely used in cryptographic protocols. Due to the stealthy nature of PUFs, the verification of these properties is in itself a difficult task. In this paper, we survey the current trends regarding those aspects. An international standard working draft is described...
The access to information globally and by a significant percentage of the world population is an indispensable part of our daily routine. With this global network access comes the increased possibility of malicious attacks and unauthorized access to identity, information, and other resources. In order to curb the latest threats resulted from the internet revolution in the past few years many quick...
Smart systems are miniaturized devices integrating computation, communication, sensing and actuation. As such, their design can not focus solely on functional behavior, but it must rather take into account different extra-functional concerns, such as power consumption or reliability. Any smart system can thus be modeled through a number of views, each focusing on a specific concern. Such views may...
Estimation of bus travel time is one of crucial issues for passengers to let them know their departure time and arrival time at the destination, and to reduce their waiting time at the bus stop. Furthermore, it can also help to promote the development of city public transportation. To estimate bus travel time, it is worth of knowing whether target routes for passenger's travel is unstable or not,...
This paper presents a full-reference image quality estimator based on SIFT descriptor matching over reliability-weighted feature maps. Reliability assignment includes a smoothing operation, a transformation to perceptual color domain, a local normalization stage, and a spectral residual computation with global normalization. The proposed method ReSIFT is tested on the LIVE and the LIVE Multiply Distorted...
Seizures affect each patient differently, so personalization is a vital part of developing a reliable nonEEG based seizure detection system. This personalization must be done while the patient is undergoing video EEG monitoring in an epilepsy monitoring unit (EMU) because seizure detection by EEG is considered to be the ground truth. We propose the use of confidence interval analysis for determining...
AS an important technological link of LED production, LED packaging directly decides the reliability and qualified rates of LED. However, the LED packaging failure was a common problem in LED life cycle. LED packaging pollution, which as one of many LED packaging failure reasons, was always of the focus of research. In this paper, through analyzed LED failure cases of packaging pollution, the general...
With the wide application of microelectronics packaging products in the industry, the chip have been more and more attention in the harsh environment of high temperature, high humidity. Therefore how to rapidly deliver high reliability products to market has been one of the issues of concern in the microelectronics industry. However moisture sensitivity level (MSL) analysis in microelectronics packaging...
Proprioception is essential for planning and controlling limb posture and movement. In our recent work, we introduced a standardized robot-aided method for measuring proprioceptive discrimination thresholds at the wrist to obtain reliable and accurate measures of proprioceptive acuity. Weber's law defines discrimination thresholds as a constant ratio between the just noticeable difference and the...
Sample sizes and, consequently, statistical power have a large influence on the reliability of statistical results, but they are often neglected when planning and reporting studies of brain-computer interfaces (BCIs). This may be in part due to the limitations of classical power calculations, which do not apply to nested experimental designs, that are usually employed in BCI research. In this paper...
In visual object tracking, exploiting correlation filters to track the target of interest has been flourished, and, by adopting a circulant form of an image or feature descriptors jointed with the convolution theorem, these correlation filter trackers surpass many of the previous state-of-the-art trackers in both tracking speed and stability. Nevertheless, when the appearance of the target object...
The SKA phase 1 correlator, beamformers, and pulsar processing systems will be the largest built for radio astronomy. Just the raw correlation processing is close to 5 Tera arithmetic operation per second, with beamforming and pulsar search each being a similar order of magnitude.
This paper presents a fair and non-discriminatory method in losses charge allocation. Traditionally, the method of allocating the charge to the consumer (generators and loads) is widely based on bilateral contract or postage stamp methods. Recently, the introduction of power tracing in searching the true sense of losses allocation in the real system has been implemented. However, this method requires...
Power system interruptions have financial impacts for the utility, the customer and the community. A consistent approach to financial impact assessment for both planning and operations starts with fault data. Faults can be categorized and correlated with season and time of day in a time-element matrix. Statistical data can be modeled with Beta probability density functions. The paper shows how the...
