Classical-style poetry is a neglected genre in the study of Chinese American literature. Except for the Angel Island Poetry and the Songs of Gold Mountain （Jinshan geji 金山歌集）, no substantial research has been done on the enormous amount of classical-style poems published in San francisco and New York. This article attempts to explore this uncharted territory by examining the poetry of Tung Pok Chin 陈松柏（1916-88, aka Lai Bing Chan 黎屏尘） and his story as a Chinese immigrant. Chin moved to the United States in 1934 as a paper son. He joined the American navy during World War II and eventually established his own laundry business in Brooklyn. Since the late 1940s, Chin published a significant amount of his classical-style poetry in the China Daily News （Meizhou huaqiao ribao 美洲华侨日报）, a left-wing newspaper operated by the pro-communist Chinese Hand Laundry Alliance. With the help of his daughter, he also wrote a memoir in English narrating his assimilation into American society. His poetry, though not particularly refined, similarly records his experiences and comments regarding American life and politics. Based on the source materials found in the Tung Pok Chin Papers archived in New York University, his memoir, and the poems he published in the China Daily News, herein I illuminate how Chin adopted a traditional form of poetry as his expressive vehicle and, with the narrative power of his English memoir, how he used his poems to construct a social identity. The article also relates Chin＇s work to the broader context of Asian American studies, as well as the classical poetry community and its development in New York, and ponders his significances in the history of Chinese American literature.

A revival of ci writing was witnessed in the qing dynasty. Emerging with this resurgence was the founding of scores of ci societies. After the fall of the Qing, some loyalists and traditional literati, following the examples of their predecessors, joined together to form a number of ci societies in Republican China. for loyalist-lyricists such as Zhu Zumou, ci writing was not just one of the effective ways to convey their memories of the past. It also meant to be a gesture of practicing and preserving traditional Chinese culture. However, due to ideological bias, their works and the vitality of c/she did not receive sufficient attention from literary historians in the past. This paper attempts to reveal and examine the interesting features of c/she in the Republican era, asserting that within the collective voice of and harmonious correspondence among the traditional lyricists, there were always some dissonances occurred. first I delineate a general picture of ci societies in Republican China, explicating the geographical distribution and social networks of ci lyricists and why lyricists from the Qing loyalist faction can associate with members of the anti-Manchu Southern Society （Nanshe）, and what this phenomenon means to us. Then I focus on the foam Society （Oushe）, the ci society formed in Shanghai before the Japanese occupation of the city, and its group ci composition. Besides recounting Oushe members＇ backgrounds and the details of their ＂refined gatherings,＂ I will bring into light the multifaceted thematic and stylistic features displayed in the members＇ works.

This work presents a memetic Shuffled frog Leaping Algorithm(SfLA)based tuning approach of an Integral Sliding Mode Controller(ISMC)for a quadrotor type of Unmanned Aerial Vehicles(UAV).Based on the Newton–Euler formalism,a nonlinear dynamic model of the studied quadrotor is firstly established for control design *** the main parameters of the ISMC design are the gains of the sliding surfaces and signum functions of the switching control law,which are usually selected by repetitive and time-consuming trials-errors based procedures,a constrained optimization problem is formulated for the systematically tuning of these unknown *** time-domain operating constraints,such an optimization-based tuning problem is effectively solved using the proposed SfLA metaheuristic with an empirical comparison to other evolutionary computation-and swarm intelligence-based algorithms such as the Crow Search Algorithm(CSA),fractional Particle Swarm Optimization Memetic Algorithm(fPSOMA),Ant Bee Colony(ABC)and Harmony Search Algorithm(HSA).Numerical experiments are carried out for various sets of algorithms’parameters to achieve optimal gains of the sliding mode controllers for the altitude and attitude dynamics *** studies revealed that the SfLA is a competitive and easily implemented algorithm with high performance in terms of robustness and non-premature *** results verified that the proposed metaheuristicsbased approach is a promising alternative for the systematic tuning of the effective design parameters in the integral sliding mode control framework.

In modem four-stroke engine technology, variable valve timing and lift control offers potential benefits for making a high-performance engine. A novel electro-hydraulic fully variable valve train for four-stroke automotive engines is introduced. The construction of the nonlinear mathematic model of the valve train system and its dynamic analysis are also presented. Experimental and simulation results show that the novel electro-hydraulic valve train can achieve fully variable valve timing and lift control. Consequently the engine performance on different loads and speeds will be significantly increased. The technology also permits the elimination of the traditional throttle valve in the gasoline engines and increases engine design flexibility.
