Wet granulation in laboratory-scale high shear mixers: Effect of chopper presence, design and impeller speed [PDF]

open access: yes, 2011
The effect of the main means of agitation in a high shear mixer has been investigated in this study. Granulation runs have been performed on a fine cohesive microcrystalline cellulose powder (Avicel 105, d50 = 20 μm) often used as a pharmaceutical ...

Prediction Model for Preoperative Diagnosis of Ovarian Cancer Using Tumor Markers, CBC, and LFT

open access: yesEngineering Proceedings, 2023
The preoperative diagnosis of ovarian cancer (OC) was developed based on risk factor groups using secondary data. Binary and multiple logistic regression and its operating characteristic curve were used to analyze the data of risk factor groups for tumor

Multi-operator colligations and multivariate characteristic functions [PDF]

open access: yesAnalysis and Mathematical Physics, 2011
In the spectral theory of non-self-adjoint operators there is a well-known operation of product of operator colligations. Many similar operations appear in the theory of infinite-dimensional groups as multiplications of double cosets. We construct characteristic functions for such double cosets and get semigroups of matrix-valued functions in matrix ...

Theory Based on Device Current Clipping to Explain and Predict Performance Including Distortion of Power Amplifiers for Wireless Communication Systems [PDF]

open access: yes, 2008
Power amplifiers are critical components in wireless communication systems that need to have high efficiency, in order to conserve battery life and minimise heat generation, and at the same time low distortion, in order to prevent increase of bit ...
