The forecasting of bus passenger flow is important to the bus transit system’s operation. Because of the complicated structure of the bus operation system, it’s difficult to explain how passengers travel along different routes. Due to the huge number of passengers at the bus stop, bus delays, and irregularity, people are experiencing difficulties of using buses nowadays. It is important to determine the passenger flow in each station, and the transportation department may utilize this information to schedule buses for each region. In Our proposed system we are using an approach called the deep learning method with long short-term memory, recurrent neural network, and greedy layer-wise algorithm are used to predict the Karnataka State Road Transport Corporation (KSRTC) passenger flow. In the dataset, some of the parameters are considered for prediction are bus id, bus type, source, destination, passenger count, slot number, and revenue These parameters are processed in a greedy layer-wise algorithm to make it has cluster data into regions after cluster data move to the long short-term memory model to remove redundant data in the obtained data and recurrent neural network it gives the prediction result based on the iteration factors of the data. These algorithms are more accurate in predicting bus passengers. This technique handles the problem of passenger flow forecasting in Karnataka State Road Transport Corporation Bus Rapid Transit (KSRTCBRT) transportation, and the framework provides resource planning and revenue estimation predictions for the KSRTCBRT.
Automobile emissions are composed of NOx and unburned hydrocarbon that contribute significantly to major environmental and health issues. In this study, encapsulated Moringa oleifera beads (EMBs) were synthesized using Moringa oleifera pod powder that was cross-linked with calcium alginate and used as a biosorbent for reducing the emission gas concentrations from the single-cylinder diesel engine. The breakthrough curve was attained from single and double stage of fixed bed column by the influence of temperature ranging from (80°C–120°C) ± 5°C with a feed flow rate varying from 8 to 10 kg hr–1 and bed height varying from 15 to 30 cm. Based on the experimental results, the maximum biosorption capacity (qo) was found to be 14.45 and 123.51 mg g–1 for HC and NOx, respectively, and was obtained at 80°C–90°C with double stage of BH–30cm under flow rate of 8 kg hr–1. Further, breakthrough curves were investigated, and the experimental data were fitted using well-established models like Thomas, Yoon–Nelson, and Wang models. In addition, mass transfer models like Weber–Morris and Boyd were investigated to identify the rate-limiting step of the overall biosorption process. 相似文献
Studies were conducted with used frying oils in a flat membrane batch cell using five different types of polymeric membranes
to decrease the soluble degradation products. During membrane processing, triglycerides permeated preferentially compared
to the majority of the polar compounds including oxidation products, polymers, and color compounds. Two of the composite membranes,
NTGS-AX and NTGS-2200, selectively rejected polar compounds and oxidation products to the extent of 25–48% and 24–44% respectively.
The reduction in Lovibond color values (5R+Y) was in the range of 83–93%. The viscosity of the used frying oil was reduced
to the extent of 22%. The composite membranes were effective in reducing the soluble impurities, as well as insoluble particulates,
without causing any undesirable changes to the oil. The membrane process appears to improve the life of used frying oils and
does not have the disadvantages associated with the active filtration systems, however, for commercial application the permeate
flux needs to be improved considerably. 相似文献
The temperature scaleT* at which the amplitude of the order parameter is formed is in general much higher than theTc at which phase coherence is established in short coherence length superconductors. Using quantum Monte Carlo simulations for the attractive Hubbard model we show that for a degenerate 2D system the spin and charge responses show qualitatively different behavior in the normal state in the temperature rangeTc<T<T*. We find that
s is stronglyT-dependent whiledn/d is independent ofT. A pseudo-gap develops in the one-particle density of states and leads to anomalous behavior of the NMR relaxation rate 1/T1Ts(T) characteristic of spin gap behavior in the high-Tc materials. 相似文献
The local environment of the aluminum atoms in a series of metastable Zr(1− x )Al x O(2− x/ 2) crystalline materials (0.08 ≤ x ≤ 0.57), prepared by diffusion-limited crystallization of amorphous precursors, has been determined by 27Al magic angle spinning nuclear magnetic resonance (MAS NMR). Results show the existence of aluminum in 4-, 5-, and 6-fold coordination in both the amorphous and crystalline states. Although the relative amounts of each type of coordination show no compositional dependence in the amorphous state, the results for the crystalline materials show a systematic decrease in the average aluminum coordination number with increasing aluminum content. Comparisons of MAS NMR results between pure Al2O3 precursors and Zr (1- x )Al x O(2- x /2) crystalline materials processed under similar conditions show a profound effect of ZrO2 on the coordination environment of the aluminum atom. Both a random distribution model and a model that assumes small-scale clustering of aluminum ions are considered to explain the trends in the type of aluminum coordination as a function of composition. 相似文献
Pseudomonas mandelii KJLPB5 is reported for the oxidation of aryl alcohols in ionic liquid [hmim]Br (1-hexyl-3-methyl imidazolium bromide) with
H2O2. With a slight alteration of reaction conditions, the developed protocol leads either to (i) chemoselective oxidation of
2° aryl alcohols over 1° and aliphatic counterparts or (ii) direct one pot-two step sequential conversion of 2° aryl alcohols
into corresponding one or two carbons shorter aryl aldehydes through oxidative cleavage pathway, thus providing a new facet
to metal-free oxidations. The key operational parameters such as substrate concentration, incubation temperature, incubation
time, ionic liquid type and ionic liquid concentration are also optimized. 相似文献
