This paper describes a noise analysis of interference waveforms in swept source optical coherence tomography using a KTa1-XNbXO3 deflector. Noise reduction based on such analysis is needed for obtaining high-resolution images. The quality of the tomographic images depends on the signal-to-noise ratio (SNR) of the point spread functions (PSFs). The relationship between the noise of the interference...
The design space exploration of Networks-on-Chip (NoC) requires tools to evaluate the network performance, tune its parameters and achieve the requirements of the target application. In this context, this paper presents RedScarf, a simulation environment with graphical user interface and a set of tools that automate the design space exploration of NoCs. It presents many resources that make RedScarf...
How to design an optimal mixed H2/H∞ robust FID controller for a complex control system is of great practical importance, but it is still an open issue. From the perspective of evolutionary algorithm, this paper formulates this issue firstly as a typical constrained optimization problem by minimizing a weighted objective function consisting of the robust stability performance, disturbance attenuation...
In this paper, a compact triplexer is proposed by cascading three tilted multimode interference couplers for FTTH applications. AH components based on silicon rib waveguides. Firstly, a MMI coupler is designed to separate the 1310 nm wavelength band by using pseudo self-imaging technique. A tiled MMI coupler is then cascaded to separate the 1490 nm and 1550 nm wavelength bands. Numerical simulations...
The end of Dennard scaling has led to an increase in demand for energy-efficient custom hardware accelerators, but current hardware design is slow and laborious, partly because each iteration of the compile-run-debug cycle can take hours or even days with existing simulation and emulation platforms. Cyclist is a new emulation platform designed specifically to shorten the total compile-run-debug cycle...
Smart grid systems include many different power sources such as renewable and fossil energy basis. While collecting all type of energy on the grid, phase order, frequency, maximum voltage value and synchronization time of each power station should be known for a smooth operation of the smart grid. Therefore, the detection of peak values of grid voltages will help the smart grid operators to connect...
In general cases, particularly in developing countries, the weakness of the national electric grid is due to overloading, high temperatures and bad weather. In such systems, the interruptions of electricity supply can take several hours to days. To prevent the power deficit, consumers can use diesel generators that are very noisy and highly polluting. But, as alternative, this paper proposes a combination...
In this paper, a four-port DC-DC converter(FPC) is proposed for electric vehicle application integrated with renewable sources and energy storage system. The four port of the converter is two input, one bidirectional port, and one output. The charging, discharging states and the disturbance at the input side are controlled. The detailed analysis and simulation of the four-port DC-DC converter are...
This half-day workshop will demonstrate the use of a lottery-based simulation to teach students how to run an agile project by practicing the routine of daily meetings, coordination by mutual adjustment and tracking and reporting of progress. The objective of the simulation is twofold: to teach students the process' mechanics and provide them with insights about the implications on performance and...
This paper presents a methodology for optimizing the size of energy storage system (ESS) for maximizing the capture of energy regenerated by a train. Besides, minimization of energy consumption from the substation, in order to obtain a return on investment, has also been explored. A standard structure of rail transit system has been used here for analysis. The optimization process takes into account...

Cyber-Physical Systems (CPS) are composed of computing devices interacting with physical systems. Model-based design is a powerful methodology in CPS design in the implementation of control systems. For instance, Model Predictive Control (MPC) is typically implemented in CPS applications, e.g., in path tracking of autonomous vehicles. MPC deploys a model to estimate the behavior of the physical system...

The Cu to Cu bonding technology compared with other joint methods for IC package, it can solve the reliability problems such as electromigration, brittle intermetallic compound or other issues. At present, Cu to Cu bonding methods have been wide developed, but the microcosmic mechanisms of Cu to Cu...
Traditionally, the using an analog-to-digital conversion demands agreeing with the requirements of Shannon, Nyquist and Kotel'nikov theorem. According to this theorem, the frequency of the conversion should, at least, twice exceed the upper boundary frequency of the spectrum of the converted signal. It is also traditionally considered that the presence of high-frequency noises of more than one quantization...
