Ion implantation is a widely used technology in current ULSI process. Spot beam and parallel ribbon beam are the most commonly used as ion beam in batch wafer type or single wafer type ion implanter. As spot beam batch type ion implanter has been used over recent decades, parallel ribbon beam single type ion implanter emerges excellent performance such as beam angle accuracy, defects, contamination,...
Giving consideration to the bidirectional uncertainty of wind power output and load, in order to improve the accuracy of reactive power optimization of asset allocation, the paper combines the wind power output scenario with complete-bus load clustering method in distribution network, and establishes the selection model of system operation scenario. This method can accurately select the system operation...
This paper discussed how to reduce cross talk and SSO noise to improve signal integrity for 3D PKG-VERTICAL CONNECTION UNIT. Due to the demand of high level IC integration, 3D packaging technology with multi-dies/chips in one package get rapid development. Traditional wire-bond multi-die stack package type have been unable to meet the challenge. TSV process seems to be an ideal solution, but with...
The wavefront matching method for the waveguide discontinuity problem is newly developed in this study. The developed method can be applied to optimize the waveguides including reflection. The application for silicon mode converters are demonstrated and ultrasmall and low-loss structure is obtained.
The investigation of methods to support the ever increasing demand for data transfer has continued for years; one such method suggested within the field of optical communication, is space division multiplexing (SDM) [1]. Simultaneously the field of photonic integrated circuits (PICs) is being investigated due to attractive features such as high device density and low operating power [2]. For PICs...
This paper focuses on quickly identifying the unknown or time-varying random latency probability (RLP) of the measurements in the nonlinear networked multi-sensor system by resorting to the efficient implementation of maximization likelihood (ML) estimation. Firstly, the full-probability likelihood computation is equivalently transformed into a log-likelihood function summation form parameterized...
The paper deals with human-computer interaction in which the cooperation leads to solve a difficult issue of discrete optimization. Considered jobs scheduling problem in a robotic cell consisting of two machines and a robotic operator. Only one of two machines can work at a time and there are setup times between successive operations on a machine. The goal is to determine a schedule — permutation...
The article is about the sequencing optimization of products with high diversity in a production line to ensure a saving of time. The optimal sequencing aims at realizing products according to an order which assures a minimal change of tools. So and by exploiting the Group Technology methods. The similar products pass successively in the production. An industrial case is presented in a context where...
Pass-gates logic is known to be intrinsically more energy efficient than static CMOS. This feature attracted the research interest over the years and many working implementations have been demonstrated. Recent works, in particular, have shown that pass-gates logic is well suited for ultra-low power adiabatic circuits mapped on emerging technologies.
Last two decades some architects have used tools, which are based on nature principles. Thanks to globalization and multidisciplinary, contemporary architecture uses principles based on computing design, engineering, sociology or nature systems. Implementation of these principles brings new possibilities to architecture and design and new ways how to develop it. This paper focuses on intelligence...
This paper studies power allocation and relay selection strategies in energy harvesting cooperative wireless networks for end-to-end signal-to-noise ratio (SNR) maximization. Energy cooperation via wireless energy transfer is also considered to efficiently utilize harvested energy. Particularly, different optimal strategies are formulated as optimization problems, which are non-convex. Intelligent...
In this paper, power allocation over time-varying multi-user multi-relay amplify-and-forward networks is studied. Specifically, stochastic network sum-rate and max-min rate power allocation problems are formulated. However, solving such stochastic problems relies on perfect global instantaneous channel state information (CSI), and thus entails complex computations and excessive communication overheads...
This paper focuses on the resource allocation in a full-duplex (FD) multiuser single cell system consisting of one FD base-station (BS) and multiple FD mobile nodes. In particular, we are interested in jointly optimizing the power allocation (PA) and subcarrier assignment (SA) for uplink (UL) and downlink (DL) transmission of all users to maximize the system sum-rate. First, the joint optimization...
In this paper, we develop a resource allocation algorithm for uplink of in-band full-duplex (FD) cellular networks. The FD cellular network is assumed to be based on orthogonal frequency division multiple access (OFDMA) and consists of a base station communicating with multiple users. Some of the users in the network act as relay for other users and help them to transmit their data to the base station...
Triple material double gate (TMDG) tunnel field-effect transistor (TFET) can be considered as a potential nominee for next generation low power high speed device fabrication. In this study, the effect of Si film thickness on performance of TMDG TFET is analyzed using two dimensional TCAD simulations. The tunneling current is substantially dependent on device thickness and the device physics regulating...
Hierarchical Task Network Planning is an Automated Planning technique. It is, among other domains, used in Artificial Intelligence for video games. Generated plans cannot always be fully executed, for example due to nondeterminism or imperfect information. In such cases, it is often desirable to re-plan. This is typically done completely from scratch, or done using techniques that require conditions...
As integrated circuit technology advances, we are now facing the utilization wall of the chip, which prevents us from turning on all the cores at the same time and leads to dark silicon. In order to maximize performance without violating thermal threshold for dark silicon chips, we propose a new power budgeting and dynamic thermal management scheme. Utilizing model predictive control, the new method...

In quest for high spectral fidelity in spatial superresolution of multispectral images, we explore physically-induced, joint spectral-spatial sparsities. The bichromatic image formation model is used to reveal that the discontinuities of a multi-spectral image tend to align spatially across different spectral bands; in other words, the 2D Laplacians of different bands are not only sparse but also...
