Serious tungsten corrosion after tungsten chemical mechanical planarization (W CMP) is found to correlate to the high via resistance. According to via design layout analysis, the W plug recess is strongly dependent on the underlying metal line area and via hole size. The via W plug recess becomes worse as via size shrinkage and underlying metal line area increasing. The low corrosion W polishing slurry,...
Predicting the gap between taxi demand and supply in taxi booking apps is completely new and important but challenging. However, manually mining gap rule for different conditions may become impractical because of massive and sparse taxi data. Existing works unilaterally consider demand or supply, used only few simple features and verified by little data, but not predict the gap value. Meanwhile, none...
In recent years, the use of license plate recognition technology in traffic monitor has attracted a lot of attention because it can be used in a smart city to do criminal investigation and traffic detection. License plate recognition technology has been widely used in parking lot management systems which has fixed shooting angle and lighting environments. The license plate recognition used in traffic...
Surface modeling of spraying work-piece is the first step of spraying robot path optimization. In this paper, a surface modeling method is proposed by using Bézier curves. The Bézier polynomial surface is constructed based on Bernstein polynomials. And each triangular in the surface of the Bézier triangular surface is called the B-B triangle. The B-B triangulation algorithm is proposed. Then a new...
While performing five-axis machining, it is usually expected to complete all the cutting without having to re-clamp the workpiece. In other words, the workpiece should remain at the same location during the whole five-axis machining process. The current procedure to perform five-axis machining on a workpiece is to use CAM software to generate the tool paths and then perform a simulation or real cutting...
“R & D efficiency” and “systematic management” are two major key issues concerned in this research. This paper considers how to apply TRIZ methods to improve product lifecycle management in enterprise, and establishes the contents of product development portfolio at the design stage. The proposed scheme is founded on the four pillars of TRIZ: Functionality, Resource, Contradiction and Ideality...
The administration of hot spring in Taiwan has collected and checked the data of hot spring level these years. Unique temperature and quality of the hot spring usually caused the device recorded and missing data. The data analysis used the gray theory in order to supplement the data of hot spring level.
In this paper, we proposed the high transparent digital television (DTV) antenna. The used transparent material is based on nano-structured thin film coating on the glass substrate for achieving the transparency up to 80%. The substrate dimension size of the proposed design is 200 × 150 mm2. The proposed antenna has radiation efficiency of 66.52% and having the bandwidth of 0.46–0.66 GHz. The proposed...
Modern city intelligent transportation system urgently demands high accuracy real-time map matching methods. Because of inaccurately measured locations, a GPS point can be assigned to many road segments depending on the topology of the road network and GPS measurement, especially in the complex urban traffic environment. Taking some object motion laws, such as speed limitations and acceleration constraints,...
Business process management(BPM), contributes to support the design, enactment, management, and analysis of operational business processes for a lot of important applications, such as banking, medical field. The business process is usually described by Petri net, BPMN, and other modeling languages, and the model structure also confirms all instances produced by these networks. Queries and analysis...
This paper presents the methods of eliminating the plasma-induced Si substrate damage in periphery regions, resulting from high aspect ratio etching process for 3D NAND fabrication. The impact of Si substrate damage is verified by the low and high bias power experiments. The result indicates more Si damage is present with high energy bombardment; therefore, high bias power is recommended to be inhibited...
Attention mechanism advances the neural machine translation (NMT) by reducing the confusion introduced by irrelevant words in long sentences. However, the confusion caused by ambiguous words hasn't been handled yet and it may be a bottleneck for the NMT model. This paper validates the hypothesis and proposes a simple and flexible framework, which enables the NMT model to only focus on the relevant...
Neural machine translation (NMT) has shown promising results and rapidly gained adoption in many large-scale settings. With the NMT model being widely used in empirical productions, its long-standing weakness in handling the rare and out of vocabulary words has been amplified a lot. In order to release the model from the stress of “understanding” the rare words, copy mechanism has been proposed to...

Outdoor sports equipment without maintenance usually caused injury to users. This paper proposes to design an App notification system combine with IoT to monitor the equipment status. We converted our action signal into frequency domain for analysis. But the useless signal might decline classifier efficiency. Therefore we propose an empirical support vector machine (SVM) to reduce the useless signal...
Multi-temporal PolSAR data is suitable for crops classification and growth monitoring. It is still difficult to establish a classifier with good robustness and high generation over a long temporal acquisition duration. This work aims to provide a solution to this task by exploring benefits from both the target scattering mechanism interpretation and the advanced deep learning. A polarimetric-feature-driven...
To provide immersive freehand painting experience, we proposed a flexible airbrush model making use of the hands tracking capability of Leap Motion Controller. The airbrush model uses a common screen as the painting canvas. When the user moves hands over the screen, the brush model continually acquires his/her hands movement data and extracts multiple control signals which describes multiple gestures...
Impact crater is the major geomorphic feature on the lunar surface. More than 8.2 million valid data samples were obtained by the Chang'E-l Laster Altimeter(LAM) and the craters are hidden among them. In order to visualize the topographical structure of these craters with high accuracy and computational stability, a novel scattered data fitting method was proposed in this paper. Based on the characteristics...
This paper considers a discrete-time modulus consensus model in which the interaction among a group of agents is described by a time-dependent, complex-valued, weighted digraph. It is shown that for any sequence of repeatedly jointly strongly connected digraphs, without any assumption on the structure of the complex-valued weights, the system asymptotically reaches modulus consensus. Sufficient conditions...
MapReduce applications, which require access to a large number of computing nodes, are commonly deployed in heterogeneous environments. The performance discrepancy between individual nodes in a heterogeneous cluster present significant challenges to attain good performance in MapReduce jobs. MapReduce implementations designed and optimized for homogeneous environments perform poorly on heterogeneous...
