    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.

  • FPGA Implementation of Gate Level Modified Adaptive Filter Architecture for Noise Cancellation Application   Order a copy of this article
    by Gomathi Swaminathan, Murugesan G 
    Abstract: This paper provides an approach for the implementation of modifications in the gate level in the adaptive filter architecture. An adaptive filter is appreciable when processing real time data and under the conditions when the signal statistics are not known a priori. Filtering data in real time needs a dedicated hardware. The resources available for implementing an efficient digital filtering algorithm are present in Field Programmable Gate Array. To design a dedicated hardware with low computational complexity, an approach of gate level modifications is incorporated in the EX-OR gate and the modified EX-OR gate is implemented in the coefficient decimation method. The proposed modified coefficient decimation method is applied in the adaptive algorithms such as Recursive Least Square, Affine Projection, and Kalman algorithm. The designed structures are experimented with the ECG and speech signal and implemented in the Xilinx Virtex 5 FPGA. Simulation and implementation results infer area reduction is achieved up to 50% and delay reduction of 10% is obtained in the proposed structures.

  • TWO DIMENSIONAL CUTTING STOCK PROBLEM WITH MULTIPLE STOCK SIZES   Order a copy of this article
    by Umutcan Ayasand?r, Meral Azizoglu 
    Abstract: In this study, we consider a two dimensional cutting stock problem with multiple stock sizes and two stage guillotine cuts. Our objective is to maximize the difference between total revenue earned over all cut items and total cost spent over all used panels. We propose two mathematical models, derive some optimality properties and use them to enhance the performances of the models. We develop decomposition-based heuristics that use the best of the proposed models to solve the subproblems. The results of our computational study have revealed that the models can return optimal solutions for the instances with up to 30 items in 2 hours and the heuristics produce near-optimal solutions for the instances with up to 50 items in 5 minutes.

  • Reallocation and Imported technology: Evidence from Vietnam manufacturing Sector   Order a copy of this article
    by Nguyen Khac Minh, Phung Mai Lan 
    Abstract: The objective of this study is to measure the contribution of "high- tech" importers (high-tech firms) to the productivity growth of the Vietnamese manufacturing industry. This analysis uses augmented Olley - Pakes static and dynamic productivity decomposition and the annual panel industrial survey data from the period of 2012-2016. The results indicate that high-tech firms account for only 20.8% of total firms but contribute 59.6% to productivity growth. The static decomposition shows that the reallocation process is an important mechanism for increasing the industrial productivity. The dynamic decomposition indicates that the exiting firms are the factor that reduces productivity growth while learning by doing and improving technology within the firm are limited and only significantly contribute in high-tech firms. The results also shows that high-tech importers not only increase their productivity but also become stronger in the market. The spillover effect from the high-tech firms is stronger than that of foreign-owned firms.

  • Capability management of manufacturing research centres: challenges and opportunities   Order a copy of this article
    by Olga Uflewska, T.C. Wong, Michael Ward 
    Abstract: This paper is the first to investigate capability management of manufacturing research centres within the High Value Manufacturing Catapult (HVMC). The HVMC was established to address the valley of death by bridging the gap between industry and academia in order to drive the UKs economic and technological growth. However, the current literature does not fully recognise capability management of manufacturing research centres, and hence overlook its link with operations management and strategic management within research centres environment. Regarding technology capabilities, manufacturing companies usually adopt their own measurements or assessment tools such as Technology Readiness Levels (TRL) or Manufacturing Readiness Levels (MRL) to track their technological progression. These tools, however, are not sufficient to devise important capability management practices due to research centres unique operating characteristics. It is evident that standardising such practices within the HVMC is vital, and this drives the need of developing a new capability management framework.

    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, and 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.

  • 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.

  • Automatic Feature Based Inspection and Qualification for Additively Manufactured Parts with Critical Tolerances   Order a copy of this article
    by Christopher Kelly, Richard Wysk, Ola Harrysson, Russell King, Brandon McConnell 
    Abstract: This work expands the capabilities of the Digital Additive and Subtractive Hybrid (DASH) system by including "geometric qualification" of mechanical products. Specifically, this research incorporates the extended Additive Manufacturing Format files (AMF-TOL) which include American Society of Mechanical Engineers (ASME) Y14.5 specifications for planes, cylinders and other features so that "in-process" inspection can be completed automatically. An example for the production of hols is provided to illustrate On-Machine-Measurement collects sample radii to estimate the size and position of finished cylindrical features. Statistical analysis was used to measure bounds for comparison to specified tolerance callouts to determine whether a part is within specification, within a user-defined level of confidence. Seven different sampling strategies were evaluated on a DASH part including the bird cage sampling strategy defined in ISO-12180. Part data was utilized to show that for large data samples no statistically significant difference in accuracy was identified for four methods. Finally, analysis shows that using the DASH process with automatic inspection is economically advantageous for low volume production runs.

  • 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.

    Abstract: In order to solve the shortcomings of traditional methods such as high Hamming loss value and low demand supply rate, a multi product supply chain scheduling method based on hybrid genetic algorithm was designed. 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.

    Abstract: In order to overcome the problems of traditional warehousing location methods, such as time-consuming and low positioning accuracy, a real-time positioning method for electric power materials warehousing based on RFID technology is proposed. Firstly, the weight centroid between the electrical materials to be measured is determined by the trilateral measurement method to complete the distance measurement of electrical materials in storage. Secondly, determine the proportion of the weight of the location of electrical materials in storage, and set the electrical materials storage label with the help of Gaussian filter. Finally, RFID technology is introduced to analyze the probability of collision of electronic labels of warehousing materials. With the help of time stamp calculation, the collision of electronic labels is avoided and the warehousing location of materials is completed. The experimental results show that the positioning accuracy of this method is high, and the highest positioning accuracy reaches 92%.
