Three dimensional ICs are expected to bring about a new generation of integration by allowing for a smaller footprint, faster operation, and lower energy consumption. Manufacturing defects in through-silicon via (TSV) and disconnection defects among tiers are concerns in this new technology. To prevent yield loss from these defects, confirming known-good-die (KGD) and known-good-stacks (KGS) by test...
In current scenario, the need of surveillance applications, technological improvements, and the numbers of active real-time surveillance systems are increasing continuously throughout the world. In this research work, we have presented a background subtraction based scheme for moving object detection in video frames. The proposed scheme has a strong potential for applications in consumer electronics...
This paper describes a new model for studying impulse noise in metallic lines and offers theoretical base for modeling of impulse noise in digital communication systems intended for use with medium-voltage power distribution lines.
Next generation coherent optical communication systems can potentially employ new architectures such as colorless, filterless, gridless and highly-sensitive features. This paper discusses and demonstrates advanced receiver design that is targeted for such applications.
Understanding the total mass balance of Earth's polar cryosphere is a significant aspect of estimating sea level rise due to climate change. Measuring ice sheet elevation and ground height is essential for determining the total glacier mass balance. Satellite-based and airborne photon-counting lidar sensors, such as the upcoming Ice, Cloud and land Elevation Satellite 2 (ICESat-2), will provide accurate...
The features of complexity and dynamism characterize a social network and its processes. A network node, to perform a decision-making process, will have to consider its personal knowledge and also the influences received from its surroundings. The relationships of each single node change over the time, according to the dynamic evolution of the social network, altering at each time the relations between...
In this paper, figures of merit describing the performances of infrared (IR) bolometer sensor such as thermal response time (τ), responsivity, detectivity (D), noise equivalent power (NEP) and noise equivalent temperature difference (NETD) are estimated using numerical simulations. The proposed model is based on the analytical formulas from Frank Niklaus, et.al. Using this model, we...
In many robotic problems, optimization of the policy for multiple conflicting criteria is required. However this is very challenging due to the existence of noise, which may be input dependent, or heteroscedastic, and the restriction in the number of evaluations, due to robotic experiments which are expensive in time and/or money. This paper presents a multiobjective optimization (MOO) algorithm for...
Power supply noise has been becoming critical in advanced CMOS digital systems, because power supply noise induces false logic operation and instability. Especially, anti-resonance peaks in power distribution network (PDN) due to the chip-package interaction induce the unwanted power supply fluctuation. In this paper, power supply noises and total impedances of power distribution network (PDN) for...
As the need of highly secure data transmission in wireless communication has increased rapidly, physical layer security gains a lots of attention recently. The transmission of confidential data between two legitimate users in the existence of the passive eavesdropper with quasi-static Rayleigh channel is considered. A new technique is proposed in which a friendly noise is incorporated with confidential...
We demonstrate robust error-free transmission of 51.56 Gbit/s PAM-4 over multiple examples of 100m of multimode fiber with 905nm VCSELs. We further demonstrate the need to include level dependent RIN when assessing impairments and predicting performance of PAM-4 MMF links.
This paper investigates and evaluates coupled inductors in interleaved multiphase three-level DC-DC converters. If non-coupled inductor is used and maintaining the inductance of inductor, multiphase three-level DC-DC converter interleaving operation will increase the inductor current ripple, although the overall output current ripple and common mode voltage will be smaller. To reduce the inductor...
Conventional analog Pulse-Width-Modulation (PWM) Class D Amplifiers (CDAs) require analog input signals that are typically provided by a Digital-to-Analog Converter (DAC). A PWM-in PWM-out CDA, on the contrary, is able to receive digital PWM signals as its input signals, hence not requiring said DAC as the ‘interface’ to digital signal processing circuits. In this paper, we analytically investigate...
A potential technology by silicon interposer enables high bandwidth and low power application processing devices of the future, because the demand of smart mobile products are driving for higher logic-to-memory bandwidth (BW) over 30 GB/s with lower power consumption and ultra-memory capacity. This paper presents a 2.5D-IC structure with silicon interposer to demonstrate electrical performances including...
The analysis model of non-woven fabric made of synthetic fibers having different diameters for the non-magnetic noise suppressor is developed and the relationship between the wave impedance of free space is considered. The shielding effectiveness to the plane wave can be calculated using the sheet resistance by regarding the non-woven fabrics as a continuous metal sheet. Therefore, it is shown that...
Human standing is characterized by large body sway, which cannot be explained by linear control. In past researches, sway has been considered as an uncontrolled biological noise. In contrast, we consider the sway to be a cyclic motion generated by continuous proportional-integral-derivative (PID) control with weak nonlinearlity. Through mathematical analysis of nonliner PID control, cyclic motion...
According to noise and low frequency redundant problems generated by analyzing non-stationary signal with empirical mode decomposition (EMD) method, this paper proposes an improved EMD method which uses instantaneous frequency weighed average algorithm to eliminate noise component and correlate coefficient significant test to eliminate low redundant components. The improved EMD method which can obtain...
Wireless body area networks (WBANs) is an emerging technology which consists of a network composed by miniaturized and intelligent sensor nodes in order to monitor a variety of applications. Due to the lack of overall, wireless technology, the special challenges of WBANs, the IEEE 802.15.6 was proposed to solve these issues in this emerging area and to satisfy the requirements for a monitoring system...
This paper uses Fisher information to quantify the identifiability of internal resistance and charge capacity for a first-order nonlinear equivalent-circuit model of a lithium-ion battery undergoing periodic cycling. The paper derives analytic Cramér-Rao bounds on the variances with which a maximum-likelihood estimator can determine these parameters in the presence of white and Gaussian voltage measurement...
TOFD (Time of Flight Diffraction), one of the most advanced technologies in the field of NDT (Nondestructive Testing), is widely used in science and industry to evaluate the properties of material, component or system without causing damage. Experiments on TOFD show that signal is greatly disturbed by the noise received by the receiving probe. Based on the performance analysis of four different kinds...
