In order to improve the handling and stability of four-wheel-steering (4 WS) vehicle, a new 4 WS intelligent control system with genetic algorithm (GA) fuzzy neural network (FNN) was put forward. According to the tire cubic formula, a vehicle nonlinear dynamics model was built. Then a vehicle model based on back-propagation (BP) network was identified from(More)
Aerobic granules were successfully cultivated in a sequencing batch reactor (SBR), using a single bacterial strain Rhizobium sp. NJUST18 as the inoculum. NJUST18 presented as both a good pyridine degrader and an efficient autoaggregator. Stable granules with diameter of 0.5-1 mm, sludge volume index of 25.6 ± 3.6 mL g(-1) and settling velocity of 37.2 ± 2.7(More)
The control of off-line fuzzy neural network can realize the shift of multi-parameter automatic transmission in construction vehicles. The method is based on fuzzy look-up table database. The gear shifting dynamically acts according to the shift database. The database was established by training the fuzzy neural network and was save in advance. The shift(More)
In order to improve automobile transfer efficiency, we design a fuzzy control strategy based on genetic algorithm. Acceleration is taken as a control parameter of automatic transmission upshifting or downshifting, namely that only when acceleration is positive, automobile can be upshifted, only when acceleration is negative or zero, automobile can be(More)
Belt conveyors are widely used in the areas of coal, ports, electric power, chemical, etc, to transport bulk solid. The traditional design methods have many defects, such as long design cycle, prone to error, and it is unable to meet the needs of modern society. This paper presents a new method of designing belt conveyors, the 3D visual rapid design(More)
Inherited retinal dystrophies (IRDs) are a clinically and genetically heterogeneous group of Mendelian disorders primarily affecting photoreceptor cells. The same IRD-causing variant may lead to different retinal symptoms, demonstrating pleiotropic phenotype traits influenced by both underlying genetic and environmental factors. In the present study, we(More)
The genetic heterogeneity of Mendelian disorders results in a significant proportion of patients that are unable to be assigned a confident molecular diagnosis after conventional exon sequencing and variant interpretation. Here we evaluated how many patients with an inherited retinal disease (IRD) have variants of uncertain significance (VUS's) that are(More)
In some mechanical transmission structures, the conjugate cam mechanism is used widely. The previous design method is not only tedious, but the substantial design is not strong, difficult to form a simulation animation, and inconvenient for subsequent analysis. The equations of conjugate cams curves are derived by the analytical method. Taking the conjugate(More)
The belt conveyor is an important material-transport equipment in metallurgy, mining, ports and thermal power plants, etc. It has an important engineering significance on the belt conveyor design, management and statistics. Based on the concept of three-dimensional digital design, this paper proposes a method of adding engineering attributes to the belt(More)
