Surveillance visual systems play an important role in modern life, especially in the Internet of Things (IoTs) era. However, the limitation of bandwidth, energy resources and the heterogeneity of devices, networks and environments have been asking for a more powerful video coding solution, which provides not only the high compression efficiency but also the flexible scalability capability. In this...
The report considers the modified Peters algorithm to calculate the Hurst exponent (HE), the essential properties of HE are proved, an example, analysis of a random time series is given.
Yield improvement, yield ramp, and defect screening have been major areas of concern for the semiconductor industry as technology nodes have advanced. Much effort has been focused on capturing the defects missed by traditional stuck-at and transition delay fault model based testing. A majority of these un-modeled defects stems from features inside a standard cell or between two adjacent standard cells...
As a natural dual object of symmetric game (SG), the skew-symmetric game (SSG) is proposed and investigated in this paper. First of all, for two player games, it is shown that both symmetric and skew-symmetric games are subspaces of finite games. Moreover, using the Euclidean space structure of finite games, it is proved that the skew-symmetric games form an orthogonal complement of symmetric games...
Implantable medical device (IMD) with on-chip antenna (OCA) has got an increasing attention for the biotelemetry applications to monitors the patient's health condition by transmitting the sensed bio-signal to the monitoring device outside the body. This paper presents a novel OCA designed by using standard 0.18um CMOS technology to operate at ISM 2.45 GHz. Using two oxide layers namely, Silicon dye...
This scientific paper contains the analysis of common MPPT algorithms and usual data processing algorithms for the purpose of the power optimization of mobile solar generators. Furthermore according to the analysis results, an optimized MPPT algorithm, the Global High-Dynamic MPPT algorithm, is designed. The design process approaches, and superordinate algorithm theoretical principles are described.
In this paper, we described a miniaturized microfluidic device able to electro-loading small volumes (200nl) of biologic samples via ElectroWetting on Dielectric (EWoD) actuation and detect DNA via polymerase chain reaction (PCR). The miniaturized silicon-based chip contains 48 microchambers properly chemically treated for EWOD process. The device was designed to contain also integrated temperature...
This paper presents a method for radial shift estimation of an electrode array located around the forearm. The algorithm is aimed at band-shaped EMG human-machine interfaces recognising hand gestures. Proposed algorithm relies on the approximation of muscle activity in several regions arranged radially around user's forearm. The intensity is represented as a polygon on a polar plane. To estimate current...
This study compared the results of room temperature direct wafer bonding of SiC-SiC accomplished by standard surface activated bonding (SAB) and modified SAB with a Si-containing Ar ion beam, in terms of bonding energy, interface structure and composition as well as the effects of rapid thermal annealing (RTA). Compared with that obtained by standard SAB, the bonding interface of modified SAB with...
In this paper, signal integrity (SI) and EMI aspects of a novel Flyover Quad Small Form Factor Pluggable (Flyover QSFP) connector is compared to a traditional QSFP connector which are used in 28/56 Gb/s applications. The flyover technique can overcome the limitation of high insertion loss associated with standard surface mount QSFP connectors that use PCB Microstrip traces. In flyover QSFP, substituting...
High Availability (HA) is a quality of service that is required for many services, e.g. carrier grade services. Systems providing such services undergo upgrades, e.g. software version upgrade, like any other system. Avoiding/limiting service outage during these upgrades is of critical importance to meet the HA requirement. Thus, the upgrade campaign specifications, which drive the process need to...
Ge-on-Si has been demonstrated as a platform for Si foundry compatible plasmonics. We use laser thermal annealing to demonstrate activated doping levels >1020 cm−3 which allows most of the 3 to 20 μm mid-infrared sensing window to be covered with enhancements comparable to gold plasmonics.
This paper studies the problem of designing distributed state estimators for a class of large-scale interconnected systems. The goal is to design a local state estimator for each subsystem using local information and state estimates exchanged from neighboring subsystems. A Kalman-like distributed estimation strategy is considered where the interacting terms from neighboring subsystems are replaced...
Incorporating smoothness constraints into feature matching is known to enable ultra-robust matching. However, such formulations are both complex and slow, making them unsuitable for video applications. This paper proposes GMS (Grid-based Motion Statistics), a simple means of encapsulating motion smoothness as the statistical likelihood of a certain number of matches in a region. GMS enables translation...
This work reports on the development of new AlN-based vibrational energy harvester architecture, consisting of a standard wide beam with a proof mass shaped into the Si substrate and exploiting a matrix of deep circular holes realized on the hinge backside. This approach was effective in the increase of the mechanical strain of the holed backside (HB) structure device, when compared with the standard...
Many calibration algorithms for vector network analyzers using partially unknown standards can be stated as an eigenvalue problem. The construction of the eigenvalue problem is described and examples for line reflect match (LRM) and thru reflect line (TRL) calibrations are given. Advantages of the new algorithm are that all uncertainties can be taken into account and that it is fully analytic. A further...
Higher-order probabilistic programming languages allow programmers to write sophisticated models in machine learning and statistics in a succinct and structured way, but step outside the standard measure-theoretic formalization of probability theory. Programs may use both higher-order functions and continuous distributions, or even define a probability distribution on functions. But standard probability...
Influence maximization problem aims at targeting a subset of entities in a network such that the influence cascade being maximized. It is proved to be a NP-hard problem, and many approximate solutions have been proposed. The state-ofart approach is known as CELF, who evaluates the marginal influence spread of each entity by Monte-Carlo simulation and picks the most influential entity in each round...
Due to the high number of IT systems present in health institutions, their specificity and their usefulness in improving the delivery of health services, creates a serious problem for institutions when there are problems in the integrations between the various IS's. In this article we detail an analysis made to the state of integrations among the IS of two Portuguese hospitals. In both hospitals,...
In haptic perception information is often sampled serially over a certain interval of time. For example, a stimulus is repeatedly indented to repeatedly estimate its softness. Albeit such redundant estimates are equally reliable, they seem to contribute differently to the overall haptic percept in a comparison task. When comparing the softness of two silicon rubber stimuli, the within-stimulus weights...
