Mode-dependent H∞ Filtering for Time-varying Delays Neutral Jump Systems Based on FWM Technique
Guowei Zhao,Guangming Zhuang,Jianwei Xia,Wei Sun,Junsheng Zhao,Minsong Zhang 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.6
This paper is concerned with the problem of mode dependent H∞ filter for uncertainty Markovian jump system with neutral delay and retarded time-varying delay. By using free weight matrix (FWM) technique, the stability conditions of delay dependent are obtained under the framework of Lyapunov stability theory. Based on those result, the delay dependent conditions for full order and mode dependent Markovian jump linear filters are gained, which are expressed by Linear matrix inequalities (LMIs). Finally, a numerical example and a PEEC practical example are employed to prove the validity of the results.

Surgical Treatment for 11 Cases of Penile Verrucous Carcinoma
Sun Chuanyu,Xu Ke,Zheng Jie,Xia Guowei,Fang Zujun,Ding Qiang 대한피부과학회 2011 Annals of Dermatology Vol.23 No.-
Penile verrucous carcinoma is a rare, well-differentiated and low-grade tumor. The surgeons are deficiently aware about the biological behavior and the clinicopathological characteristic of this disease, which raises difficulties during the treatment. In our present study, the clinical and pathological data of 11 patients with penile verrucous carcinoma, aged between 49 to 85 years was retrospectively analyzed. The tumors exhibited exophytic, papillary, caulifower-like or verrucose lesions of great dimensions measuring between 2to 10 cm on the penises. The tumors were located at glans in 6 cases, invaded the coronoid sulcus in 4 cases and invaded the shaft of the penis in 1 case. Eight cases underwent partial penectomy, while the other 3 were treated with local excision. The diagnosis of penile verrucous carcinoma was confirmed by histopathologic examination of the specimens with the negative surgical margins in all the cases. Within the period of 12 to 60 months of follow-up, all the patients were disease-free with no case of recurrence and metastasis. The novel knowledge and experience of the treatment of penile verrucous carcinoma will be a useful clinical guide for surgeons in the future. (Ann Dermatol 23(S3) S346∼S349,2011)
