This investigation evaluated the impact of three mesh types (hexahedral, tetrahedral, and hybrid 12 cells) and five grid numbers (3, 6, 12, 24, and >38 million cells) on the accuracy and computing 13 costs of air distribution simulations in a first-class cabin. This study performed numerical error 14 analysis and compared the computed distributions of(More)
BACKGROUND Rectal cancer is a common malignancy with considerable mortality. This review outlines the current status of laparoscopic total mesorectal excision as a treatment option for rectal cancer and emphasizes the need for standardized approaches. METHODS We searched PubMed for the terms "total mesorectal excision," "rectal cancer," and "laparoscopic(More)
—This paper describes an underwater 300m micro underwater work tool –MUWT(named huwt-3E, stands for three functions micro electric manipulator in China).The working principle and components of multi-sensors are introduced in detail. The pressure-compensated joint is compact designed and integrated of a micro permanent magnet (PM) brushless motor, a drive(More)
The rapid prediction of the low-carbon fatty acids (C < or = 14) content in grease samples was achieved by a mathematical model established by near infrared spectroscopy combined with support vector machine regression (SVR). In the present project, near-infrared spectrometer SupNIR-5700 was used to collect near-infrared spectra of 58 samples; partial least(More)
—An accurate dynamic model is important for both controller design and mission simulation, regardless of the control strategy employed. In this paper, a dynamic model for a 3500m underwater manipulator in flow disturbance is established based on Morison method. The technique provides a direct method for incorporating external environmental forces into the(More)
The qualitative model for rapidly discriminating the waste oil and four normal edible vegetable oils is developed using near infrared spectroscopy combined with support vector machine (SVM). Principal component analysis (PCA) has been carried out on the base of the combination of spectral pretreatment of vector normalization, first derivation and nine point(More)
The self-referenced spectral interferometry (SRSI) technique, which is usually used for microjoule-level femtosecond pulse characterization, is improved to characterize weak femtosecond pulses with nanojoule based on the transient-grating effect. Both femtosecond pulses from an amplifier with 3 nJ per pulse at 1 kHz repetition rates and femtosecond pulses(More)
OBJECTIVE To investigate the feasibility and clinical characteristics of small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma. METHOD Forty-five patients with laryngeal squamaous cell carcinoma in T1-2 stage received small partial laryngectomy without tracheotomy. RESULT All patients were primarily healed and were hospitalized(More)
