    by Basanta Kumar Nanda, Debabrata Dhupal 
    Abstract: Conventional drilling of Glass Fiber Reinforced Polymer (GFRP) composite produces delamination effect due to peel-up and pull out of the layers. This research work represents drilling of GFRP rectangular workpieces with fluidized bed abrasive jet machining (FB-AJM) process using silicon carbide (SiC) abrasives. Experiments were conducted according to Box-Behnken design matrix to measure the four responses, namely, material removal rate (W), surface roughness (Ra), depth of cut (h), and taper angle (TA) by utilizing bed pressure (P), nozzle tip distance (Z) and abrasive grain size (G) as input parameters. Desirability based particle swarm optimization (PSO) was performed for the multi-objective optimization to find the optimal input parameters P, Z and G of 6 kgf/cm2, 7 mm, 260μm respectively. A single experiment was performed at the predicted optimal conditions to validate the model with minimum error. The SEM analysis of the machined composite surface revealed the initiation and propagation of cracks along with embedment of erodent particle.

Build supply time series, and sort the priority of supply chain scheduling according to the priority attribute values of backup plans in each link of the supply chain closed-loop model. Taking the shortest scheduling time as the objective function and the location constraints of the revolving warehouse as the constraints, the scheduling results are obtained by combining the genetic algorithm. In order to avoid the genetic algorithm falling into the local optimum, the simulated annealing algorithm is introduced to solve the global optimal solution of the objective function to achieve the coordinated scheduling of the supply chain. The experimental results show that this method can achieve multi product supply chain scheduling more reasonably and effectively.

  • Image dehazing network based on improved convolutional neural network   Order a copy of this article
    by Changxiu Dai 
    Abstract: Image dehazing enhances its quality by restoring the actual pixels influenced by poor light and intensity due to environmental and other factors. Hazy images are rectified to improve visibility, guidance, and object recognition through channel attribute corrections. This article introduces a pre-emptive dehazing network (PDN) using an improved convolutional neural network (ICNN) for single to multi-image dehazing. In the proposed method, neural network layers are operated for intensity-based single and multi-feature analysis. The image is split based on intensity pixels for identifying the channel corrections. This channel correction and intensity verifications are processed using CNN in different independent layers. In the CNN training, the channel correction from the hidden layers and pixel correlation from the external dataset is performed for dehazing the image pixels. The dehazed pixels are organised based on the original input organisation for verifying the similarity measure. The proposed method's performance is validated utilising the metrics similarity, error, precision, F1-score, and time complexity.

  • Design of computer image automatic processing system based on artificial intelligence algorithm   Order a copy of this article
    by Guoqiang You 
    Abstract: Automatic image processing systems are applied for recognising human faces in crowds, person identification, and face matching applications. The varying textures, input representation, and position impact detection accuracy and recognition. Therefore, this article introduces an automatic image processing method (AIPM) for face recognition (FR) using deep learning (DL) paradigm. This method extracts the textural features based on the image position and classifies them based on pixel mapping. Semantic (even) and uneven pixel variations are observed in the classification process. The semantic classified pixels are used for correlating different image segments that are further used for training the learning network. The uneven pixels classified using DL is discarded to prevent recognition errors. The DL paradigm verifies the pixel position and coordinate mapping between different inputs. The detection is improved based on the classified output for semantic and uneven pixels. The training is based on semantic and mapping pixels, for which the training is improvised using erroneous pixels. Therefore, precision is improved with controlled analysis complexity.

  • Fuzzy system for image defect detection based on machine vision   Order a copy of this article
    by Yiqiang Lai, Yongjun Qi, Xianfeng Zeng 
    Abstract: With the continuous upgrading of the industrial field, the market's requirements for product quality are also increasing, which requires more accurate product monitoring equipment. This paper analyses the composition of the vision system, and compares the collected images with the defects under manual detection based on the non-local mean denoising algorithm, and the results meet the system requirements. The experimental results show that the image size is 140*141, the distortion rate is 0.992, the image size is 120*81, and the distortion rate is 0.703. This means that the larger the image size, the higher the distortion. Before the improved algorithm, a total of 47 defects were detected, while after the improved algorithm, a total of 83 defects were detected. It can be seen that when the algorithm is improved, the number of defect detections increases significantly.

  • Pre-settlement audit in project cost management based on cloud computing   Order a copy of this article
    by Daibing Cheng, Zhongyan Luo, Rong Ju, Yong Zhang 
    Abstract: This research mainly analysed the audit method of pre-settlement in project cost management, which served as a reference for the work in this field. The basis of the pre-settlement audit was the specific information of construction material submitted by the construction party to ensure its authenticity and legitimacy, so that the benefits of investment could be fully exerted, and the ultimate goal of resources optimal allocation could be achieved. Because the pre-settlement audit was an extremely important process in the standardised project cost, there was a need to improve the audit level so that the effective management objectives could be achieved. Therefore, we introduced cloud computing to provide a certain basis for reducing audit cost effectively. The experimental results showed that the application of the cloud computing to the pre-settlement audit had produced positive effects, and the accuracy of the audit calculation could reach about 91%.
    Keywords: cloud computing; project cost management; pre-settlement work; review method.

  • Automatic human face recognition system of image processing based on BP neural network paradigm   Order a copy of this article
    by Pei Yang, Guoqiang You 
    Abstract: Observation video analysis is useful in recognising human faces in crowded and coinciding scenarios. Overlapping images result in false recognition due to non-semantic textural features. The boundary analysis varies for this process, generating segments exceeding masks of the original image. Backpropagation learning (BPL) based textural-edge detection and recognition model (TED-RM) is designed to resolve this issue. The proposed model exploits the masked and un-masked textural features for identifying the semantics of the input. After this identification process, appropriate features are analysed for semantics and correlation with the inward and overlapping video image input edges. The masked and un-masked regions' semantic features are recurrently correlated with the previous datasets for independent human faces. The mapping feature points are identified and correlated with the actual edge of the training input. The non-semantic edge points are classified for further training and validation to detect errors in further input analysis. The proposed TED-RM improves 10.84% high accuracy, 11.5% less processing time, 10.2% high true positives, 5.55% less error, and 10.6% high recall compared to existing methods.

  • Simulation of EPC consortium partnership stability and data based on prospect theory   Order a copy of this article
    by Judan Hu, Shuang Tang, Minjie Yang 
    Abstract: For the rapid promotion and healthy development of the EPC general contracting mode, this paper constructs a game model for the stability evolution of the EPC consortium tripartite cooperation relationship based on the prospect theory from the perspective of the EPC consortium led by the design unit, analyses the behavioural interaction mechanism of the game subjects and the factors affecting the system evolution, and uses system dynamics for data simulation. The results show that the rate at which the EPC consortium triad eventually evolves into a stable cooperation strategy is positively related to the initial probability, loss avoidance coefficient, gain sensitivity, and gain/loss sharing coefficient, and negatively related to the risk pursuit coefficient. The steady state of the system is influenced by the strength of penalty and the level of regulation/cooperation cost. This paper can provide insights and a theoretical basis for the long-term stable development of EPC consortium.

    by Jiandong Wang 
    Abstract: While accounting resource sharing is convenient and saves a lot of time and energy, it also brings many potential risks to the enterprise. Therefore, how to protect and manage accounting resource sharing has become a top priority. This paper mainly studies the possible risks in the accounting resource sharing life cycle and the assessment of the security management risk of accounting resource sharing under the big data technology of the internet of things. This article will use various methods to evaluate the risk of accounting resource sharing security management, use information entropy and analytic hierarchy process to evaluate the uncertainty and risk size of accounting resource sharing security management risk, and use Markov chain and Bayesian formula to calculate the risk probability. The results show that the security protection efficiency of the optimised accounting resource sharing system has increased by 6.13%, and security management risks have been effectively controlled.
