Noticeable performance degradation of IEEE 802.15.4-based wireless body sensor networks (WBSNs) caused by the mutual interference has recently drawn the attention of research communities. Frequency-adaptation is to some extent an effective solution to reduce the impact of mutual interference on WBSN's performance. However, as the number of WBSNs becomes larger, this scheme is destined to fail. In...
ReRAM devices show potential for in memory computing systems due to their capability to both store and process data via implication logic. This type of logic, which is typically implemented using the set transition, could offer reliability and performance advantage if implemented with reset switching of the device. However, the gradual transition of the reset makes it impractical. This paper presents...
The nature of Internet traffic has changed dramatically within the last few years, where a large volume of traffic is originated from mobile applications (known as apps), web based multimedia streaming, computation offloading like cloud computing and Internet of Things (IoT) etc. These types applications generate multiple parallel short lived end-to-end connections. However, the three major requirements...
Large-scale systems with arrays of solid state disks (SSDs) have become increasingly common in many computing segments. To make such systems resilient, we can adopt erasure coding such as Reed-Solomon (RS) code as an alternative to replication because erasure coding can offer a significantly lower storage cost than replication. To understand the impact of using erasure coding on system performance...
In distributed Smart Farming applications, a reliable communication is often crucial, in particular during collaborating operations. In rural areas, the network connectivity via Public Land Mobile Networks is, however, not always sufficient. Network disruptions may occur hindering reliable transmissions. For the delivery of periodic sensor data streams of agricultural machines, several modern communication...
The need for performance has motivated the increasing adoption of solid-state drives (SSD) both in personal computers and data centers. However, the high cost per gigabyte and reduced lifetime hinder the thorough replacement of hard disk drives (HDD) with SSDs. To mitigate these issues, several architectures have been conceived based on hybrid storage systems, but performance and dependability models...
In this work, we present an innovative method which enables to solve fundamental limitations affecting graphene-based chemi-sensors operating under environmental conditions, namely the lack of signal saturation and the scarce recovery after the detection step. The method, which exploits the differential current instead of the current itself, is validated by applying it on different devices having...
Today, performing life tests on power semiconductor devices is of major importance in industrial and automotive power applications. Traditionally, qualification tests, like the HTOL test, are carried out in a semi-automated manner. This paper first reviews different test methods and a recently proposed modular test system (MTS) that allows testing of individual devices as well as application specific...
Advancement in digitization gave rise to a new paradigm of communication, called Internet of Things (IoT), where various heterogeneous physical objects (IoT devices) with embedded intelligence can provide or receive services from each other seamlessly. One concerned issue is to maintain reliability in the system with these heterogeneous devices for effective utilization of services. Trust and Reputation...
This paper explores the feasibility, in terms of performance and reliability, of gain-cell embedded DRAM (eDRAM) to be operative at sub-threshold range, when they are implemented with 10nm FinFET devices. The use of individual transistor resizing in order to achieve better cell performance (i.e. retention time, access time, and energy consumption) at the sub-VT operating level is studied. In this...
This paper presents Thales main results for the maturity development activities of TopAxyz MEMS Vibrating Beam Accelerometer (VBA) using a differential resonator architecture implemented on a planar SOI silicon layer. Proof of concept with Navigation grade performances level has already been presented at ISS2012. Development focused on two major challenges: to reach a high production yield and to...
This paper discusses the reliability characteristics of power electronic devices in aerial vehicles. Either to enable higher degree of electrification of aircrafts or to realize aircraft design with innovative configurations, the importance of electrical networks in aerial vehicles have increased. Based on an observation on the emerging roles of electrical networks in aerial vehicles, the potential...
In this paper, a failure analysis on ball grid array (BGA) solder joints is revealed with the aid of scanning acoustic microscope (SAM), optical microscope (OM), scanning electron microscope (SEM) and strain tester. By employing both the nondestructive analysis and destructive analysis, it was found that crack of several BGA solder joints caused the failure of the printed circuit board assembly (PCBA)...
With the technology scaling of solid state drives (SSDs), data reliability has to be ensured by advanced Low-Density Parity-Check (LDPC) codes. As LDPC reads often take high latency, read performance involved in traditional garbage collection, called external GC, is largely decreased, which affects system performance. GC can choose not to correct data with LD-PC codes but just copy valid pages into...
This paper analyzes the situation and harmfulness of over-temperature using avionic device and combine with the international standard IEC/TR 62240, gives four methods of avionics device uprating. They are separately device parameter re-characterisation, stress balancing, parameter conformance assessment and higher assembly level testing, all of these provide the theory basis for over-temperature...
This paper examines the reliability issues of In2O5Sn (ITO) gate electrode (Transparent Gate) Recessed Channel (TGRC) MOSFET by considering the influence of interface trap charges polarity and density present at the Si/SiO2 interface. The reliability of TGRC MOSFET is observed in terms of Linearity and distortion FOMs such as gm, gm3, VIP3. IIP3, HD3. IMD3. Results so obtained revealed that the existence...
Glass tube sealed diode was widely used in electronics industry because of its excellent performance in air tightness, electrical insulation and so on. However, the poor performance of glass during high and low temperature circle lead to a high ratio of failure during specific experiment. By the operate process experiment and detection experiment, the influence of process factors on devices reliability...
Parity declustering is widely deployed in erasure coded storage systems so as to provide fast recovery and high data availability. However, to perform scaling on such RAIDs, it is necessary to preserve the parity declustered data layout so as to guarantee the RAID performance after scaling. Unfortunately, existing scaling algorithms fail to achieve this goal so they can not be applied for scaling...
With the development of cloud computing, disk arrays tolerating triple disk failures (3DFTs) are receiving more attention nowadays because they can provide high data reliability with low monetary cost. However, a challenging issue in these arrays is how to efficiently reconstruct the lost data, especially for partial stripe errors (e.g., sector and chunk errors). It is one of the most significant...
Robotic systems are widely used in the manufacturing industries to improve high quality products. When a fault occurs in manipulator, the faulty robot operates in abnormal condition, which causes insecurity for devices and human. In general, the dynamic of residual vector consists of fault information. In order to evaluate the residual vector, data-driven technique based on statistical theory is used...
