A new shift schedule with 4-parameter of construction vehicle was discussed and analyzed. The power train model of construction vehicle is vital to automatic shift and difficult to be expressed with mathematic model, while intelligent control is effective for solving the problem. A multi-layer back-propagation neural network (BPNN) model was proposed to(More)
Prognostic nutritional index (PNI), based on serum albumin concentration and the absolute peripheral lymphocyte count, has been used to predict survival in various tumors. Whether PNI can predict prognosis in patients with diffuse large B-cell lymphoma (DLBCL) remains unknown. We retrospectively analyzed 253 patients with newly diagnosed DLBCL in the(More)
