Since the arrival of Chinese immigrants in the 1850s, many Euro-American writers tended to project their fears, contempt, desires and fantasy onto the Other race and perceived Chinese Americans in stereotypes-dangerous villains, unassimilated aliens, quiet and passive servants, sexually submissive women, or seductive prostitutes. However in the 1970s and the 1980s Euro-American novels expressed varying attitudes towards Chinese Americans. Many earlier EuroAmerican writers began portraying positive characterizations of Chinese Americans. The purpose of this study is to examine the ways one of the Euro-American writers, Howard Fast characterized Chinese Americans in The Immigrants. Part of the novel concerns a Chinese American family. Fast gave a favorable portrayal of Chinese Americans. Unlike many Euro-American novelists who dealt only with Chinese American villains and prostitutes and view Chinese Americans as the lowest class of American society, Fast, on the other hand, portrayed Chinese Americans as law-abiding and useful citizens. Thus, I will discuss how Howard Fast subverted the familiar negative characterization of Chinese Americans and placed Chinese American experiences in the context of American immigration history. Many white Americans tended to notice only the lurid and sensational aspects in the Chinese American community. They seldom regarded Chinese Americans as people with homes and families and seldom saw Chinese Americans as individuals, as human beings with feelings, pain, and joy. To counter this racist view, Fast described the family life of Chinese Americans and depicted Chinese Americans as individuals with a full range of human emotions and with strong family and cultural ties. Though Fast debunked some myths about Chinese Americans, he also reinforces other stereotypes or some stereotypical illusions about them. In conclusion, I'll demonstrate Fast's work remains an incomplete representation of Chinese Americans.

In a known plaintext scenario, fast correlation attack is very powerful attack on stream ciphers. Most of fast correlation attacks consider the cryptographic problem as the suitable decoding problem. In this paper, we introduce advanced multi-pass fast correlation attack which is based on the fast correlation attack, which uses parity check equation and Fast Walsh Transform, proposed by Chose et al. and the Multi-pass fast correlation attack proposed by Zhang et al. We guess some bits of initial states of the target LFSR with the same method as previously proposed methods, but we can get one more bits at each passes and we will recover the initial states more efficiently.

In this paper, we propose a fast booting solution with embedded linux-based smart devices. We have divided the fast boot process into six steps, such as boot loader, kernel, file system, the init-scripts, shared libraries, and applications for an embedded linux-based boot process to improve the fast booting. Improvements for the fast boot are made in the boot loader phase, which is the first phase at power-up, and the init-script that runs the boot loader phase. To improve the fast booting, standby time from the boot loader and unnecessary initialization routine have been removed, and uncompressed kernel image loading as well as optimized copy routine have been applied. Further, a technology that replaces binary scripts in init-script phase and light-weight init process have been utilized to improve the boot.

FastSLAM which uses the Rao-Blackwellized particle filter is one of the famous solutions to SLAM (Simultaneous Localization and Mapping) problem that estimates concurrently a robot's pose and surrounding environment. However, the particle depletion problem arises from the loss of the particle diversity in the resampling process of FastSLAM. Then, the performance of FastSLAM degenerates over the time. In this work, DIR (Density Information-based Resampling) technique is proposed to solve the particle depletion problem. First, the cluster is constructed based on the density of each particle, and the density of each cluster is computed. After that, the number of particles to be reserved in each cluster is determined using a linear method based on the distance between the highest density cluster and each cluster. Finally, the resampling process is performed by rejecting the particles which are not selected to be reserved in each cluster. The performance of the DIR proposed to solve the particle depletion problem in FastSLAM was verified in computer simulations, which significantly reduced both the RMS position error and the feature error.

This paper describes to extend the fast algorithm fur the capacitance extraction of large three-dimensional object. The triangular meshes are used and refined adaptively in the area where the heavy charges reside in each iterative solving. This technique is applied to the capacitance extraction of a 68-pin cerquad package. The results show fast convergence, and this adaptive technique coupled with the fast algorithm is efficient to reduce the number of elements and computing time with least additional computational efforts in large three dimensional problems.

In this paper, a fast implementation of JPEG is discussed and its application to multimedia service is presented for mobile wireless internet. A fast JPEG player is developed based on several fast algorithms for mobile handset. In the color transformation, RCT is adopted instead of ICT for JPEG source. For the most time-consuming DCT part, the binDCT can reduce the decoding time. In upsampling and RGB conversion, the transformation from YCbCr to RGB 16 bit is made at one time. In some parts, assembly language is applied for high-speed. Also, an implementation of multimedia in mobile handset is described using MJPEG (Motion JPEG) and QCELP(Qualcomm Code Excited Linear Prediction Coding). MJPEG and QCELP are used for video and sound, which are synchronized in handset. For the play of MJPEG, the decoder is implemented as a S/W upon the MSM 5500 baseband chip using the fast JPEG decoder. For the play of QCELP, the embedded QCELP player in handset is used. The implemented multimedia player has a fast speed preserving the image quality.

Interpreting the phenomenon of Fast fashion that is prevalent these days, this research is meaningful in that it prepares the frame which suggests the vision to read the trend of 2000s and analyzes the property of phenomenon of Fast Fashion in the connection with society and culture. The so[io-cultural property can be largely characterized by consumption orientation, change orientation, efficiency, moment and multiculturism. Analyzing the phenomenon of fast fashion that emerged after 2000 on the basis of such sociocultural background, it is largely classified into imitation, fashionability, disposability, portability, transformation and convergence. Due to the hi-polarization of consumption, people tend to select imitated goods, and people accustomed to speed get interested in the fashionability of all Phenomena. Further, society that is transient and changing rapidly makes the habit of purchasing in disposability. The property of nomad society encourages to keep the habit of portability. Such change-oriented society and rapidly changing life pattern make them adapt in diverse transformation modes of Fast Fashion. Further, multi-cultural world integrates enterprises through combination of all cultures and the convergence of all factors.

The paper investigates a novel detector receiver with Kalman channel information estimator and iterative channel response equalization for MIMO (multi-input multi-output) OFDM (orthogonal frequency division multiplexing) communication systems in fast multipath fading environments. The performances of the existing linear equalizers (LE) are not good enough over most fast fading multipath channels. The existing adaptive equalizer with decision feedback structure (ADFE) can improve the performance of LE. But error-propagation effect seriously degrades the system performance of the ADFE, especially when operated in fast multipath fading environments. By considering the Kalman channel impulse response estimation for the fast fading multipath channels based on CE-BEM (complex exponential basis expansion) model, the paper proposes the iterative receiver with soft decision feedback equalization (SDFE) structure in the fast multipath fading environments. The proposed SDFE detector receiver combats the error-propagation effect for fast multipath fading channels and outperform the existing LE and ADFE. We demonstrate several simulations to confirm the ability of the proposed iterative receiver over the existing receivers.

This paper proposes a computation model of the quantity supplied to optimize inventory costs for the fast fashion. The model is based on a forecasting, a store and production capacity, an assortment planning and quick response model for fast fashion retailers, respectively. It is critical to develop a standardized business process and mathematical model to respond market trends and customer requirements in the fast fashion industry. Thus, we define a product supply model that consists of forecasting, assortment plan, store capacity plan based on the visual merchandising, and production capacity plan considering quick response of the fast fashion retailers. For the forecasting, the decomposition method and multiple regression model are applied. In order to optimize inventory costs. A heuristic algorithm for the quantity supplied is designed based on the assortment plan, store capacity plan and production capacity plan. It is shown that the heuristic algorithm produces a feasible solution which outperforms the average inventory cost of a global fast fashion company.

This study was conducted to identify the relationship among various service quality clues, brand trust, brand distinctiveness and revisit intention focusing on fast-food restaurant consumers. Using online questionnaires tool in South Korea, a total of 450 questionnaires were distributed and 390 participants were used for further statistical analysis through SPSS 21.0 and AMOS 21.0 for Windows. Four service quality factors (menu, interior, exterior, staff) were extracted from twelve questions. According to the result of this study, several service quality factors of fast-food restaurants' have positive effects on brand trust and distinctiveness. Specifically, staff and menu and exterior were significant predictors of brand trust, and staff and menu of fast-food were critical antecedents of brand distinctiveness. In addition, the brand trust has positive influence on brand distinctiveness as well as revisit intention. Although there are many studies which proved the relationships among various selection attributes and other outcome variables such as brand loyalty or image, little research explained the relationships among service quality factors of fast-food restaurants, brand trust, brand distinctiveness, and revisit intention. Therefore, present study will contribute to provide significant results and some practical implications in both the fast-food restaurant industry and academic research.
