Purpose This paper aims to develop the Hybrid feature descriptor and probabilistic neuro-fuzzy system for attaining the high accuracy in face recognition system. In recent days, facial recognition (FR) systems play a vital part in several applications such as surveillance, access control and image understanding. Accordingly, various face recognition methods have been developed in the literature, but the applicability of these algorithms is restricted because of unsatisfied accuracy. So, the improvement of face recognition is significantly important for the current trend. Design/methodology/approach This paper proposes a face recognition system through feature extraction and classification. The proposed model extracts the local and the global feature of the image. The local features of the image are extracted using the kernel based scale invariant feature transform (K-SIFT) model and the global features are extracted using the proposed m-Co-HOG model. (Co-HOG: co-occurrence histograms of oriented gradients) The proposed m-Co-HOG model has the properties of the Co-HOG algorithm. The feature vector database contains combined local and the global feature vectors derived using the K-SIFT model and the proposed m-Co-HOG algorithm. This paper proposes a probabilistic neuro-fuzzy classifier system for the finding the identity of the person from the extracted feature vector database. Findings The face images required for the simulation of the proposed work are taken from the CVL database. The simulation considers a total of 114 persons form the CVL database. From the results, it is evident that the proposed model has outperformed the existing models with an improved accuracy of 0.98. The false acceptance rate (FAR) and false rejection rate (FRR) values of the proposed model have a low value of 0.01. Originality/value This paper proposes a face recognition system with proposed m-Co-HOG vector and the hybrid neuro-fuzzy classifier. Feature extraction was based on the proposed m-Co-HOG vector for extracting the global features and the existing K-SIFT model for extracting the local features from the face images. The proposed m-Co-HOG vector utilizes the existing Co-HOG model for feature extraction, along with a new color gradient decomposition method. The major advantage of the proposed m-Co-HOG vector is that it utilizes the color features of the image along with other features during the histogram operation.

This experimental research aims to characterize the complex compound M-curcumin (M=Cu, Co, Ag) based on turmeric (Curcuma longa Linn) rhizome as a candidate for photosensitizer in solar cells. The basic material used for manufacturing the M-curcumin complex compound in this study was curcumin from turmeric rhizome extract added to Cu2+, Co2+, and Ag+ metal ions. The results of the synthesis of the M-curcumin complex were characterized by FTIR and Uv-Vis spectrophotometers. The FTIR spectrophotometer test showed a curcumin compound in the viscous curcumin extract, characterized by an absorption wave number corresponding to the curcumin compound. In the M-curcumin complex, the bond between the metal and the ligand only appears in the Co-curcumin complex at the absorption number of 498.77 cm -1. The results of the UV-Vis spectrophotometer test showed that the maximum wavelength absorption in curcumin extract was 430 nm (abs = 0.688), Cu-Curcumin complex lmax 300 nm (abs = 2.573), Co-curcumin complex lmax 425 nm (abs = 1.067), and complex Ag-Curcumin lmax 430 nm (abs = 1.36). The UV-Vis and FTIR characterization showed that the Co-curcumin complex has good potential compared to the organic compounds (curcumin) and can be used as an alternative photosensitizer in solar cells

Flexible Manufacturing Systems-FMS is a term with various types of definitions, each of them trying to describe the complexity and the generalized features. One of these features is their complexity, along with difficulties in building models that capture the system in all its important aspects. In a heterogeneous flexible system, the scheduling events or actions could be a combinatorial problem which claims a particular solution. Manufacturing scheduling process, in special for FMS, is a very difficult scheduling problem, because involves all the aspects of the processes: order, resources, transportation system i.e. automated vehicle guided, perturbation factors such as breakdowns of machine, etc. Typically, the scheduling problem is a NP-hard problem modeled in mathematical form. If we simulate n jobs or orders which have to be assigned to the m machines or resources, we will observe that the mathematical solution is a huge number that means (n!)m possibilities of solutions. The challenge of researchers is to solve this equation in a reasonable time with an optimal solution, and of course with minimal resources. Those scientists applied many solutions which became Operational Research-OR or Combinatorial Optimization-CO areas using a various methods: Local Search-LS, Artificial Intelligence-AI, heuristic method, priority rules, memetic or hybrid techniques which combine this techniques.

Today, companies often have operations distributed around the world, and production facilities and designers are often in different locations. Increased use of outsourcing and geographically dispersed supply chains further complicates the manufacturing world. The globalization of manufacturing business means that companies should be able to design, build, and maintain, anywhere at any time. Manufacturing engineers are seeking effective tools during planning to help improve production processes, plant designs, and tooling, and to allow earlier impact on product designs. Collaboration may exist in a number of activities such as (a) reviewing designs with the design team; (b) interfacing with tooling designers; (c) verifying tooling assembly and operation; (d) reviewing manufacturing process plans and factory layouts; and (e) discussing manufacturing problems with suppliers. In larger companies, collaboration is becoming increasingly important in design and manufacturing. Everyone knows something, but no one knows everything. There is an evolution from individuals working independently to functioning in workgroups, as well as enterprise collaboration and collaboration throughout a supply chain. Within a supply chain, sharing knowledge has become paramount. This chapter describes the methods of developing an Internet-enabled, integrated CAD, CAPP, CAM, and CNC system to support collaborative product development. The main goal is to provide a team environment enabling a group of designers and engineers to collaboratively develop a product in real time. STEP can be used to represent product data for heterogeneous application systems and data formats, and the Web-based Product Structure Manager developed can be an effective function module to co-ordinate collaborative activities.

Abstract Co based superalloy Mar M 509 having excellent high temperature oxidation and hot corrosion resistance is studied via the laser powder bed fusion (LPBF) process. The microstructure and mechanical properties of Mar M 509 in the as-printed (AsP) and heat-treated (HT) condition are compared, as a function of two build orientations (longitudinal (L) and transverse (T)), to establish a working range for application of the alloy. The AsP condition has a distinct cellular microstructure (500–600 nm) with 50–60 nm carbide particles decorating the cell boundaries. The L build orientation displays a strong <001> texture, has columnar grains with a grain size of 8–35 μm (along major axis) and a grain aspect ratio of 4, while the T orientation displays a more equiaxed, but bi-modal microstructure with a grain size of 5–28 μm. The room temperature mechanical properties show variability between L and T with T having 15% higher hardness and 34% higher 0.2% yield strength (YS), 30% lower elongation than L. After a short cycle heat treatment at 1250°C, the weld bead structure and cellular boundaries are broken down and there is substantial grain growth in both L (25–33 μm along major axis) and T orientations (5–42 μm), along with coarsening of carbides (250–350 nm). The dislocation density reduces substantially, indicating recrystallisation, and the lattice parameter of the matrix drops significantly, suggesting solute depletion that contributes to precipitate growth and enrichment of the carbides. There is a drop in the yield strength from 860 MPa to 740 MPa in L and from 1150 MPa to 840MPa in T and an increase in ductility from 14% to 23% in L.

Mechanical properties of a commercial out-of-autoclave non-crimp fabric epoxy prepreg (AR2527 NCF) composite were investigated in detail for the manufacturing plant elevations. To simulate the effects of elevation, the vacuum pump used for pulling vacuum from the laminate during debulking and curing was adjusted to provide two different vacuum pressures: 1) 96 kPa corresponding to 450 m elevation in Wichita KS, and 2) 84 kPa corresponding to 1550 m elevation in Denver CO. One laminate for each vacuum pressure was cured in an oven using manufacturer’s recommended cure cycle and subsequently, the laminates were machined into appropriate mechanical test coupons tested at room temperature. It was observed that the average short beam shear, combined loading compression, and flexural strength of the prepreg dropped 5%, 9%, and 12% as a result of 1100 m increase in the elevation. It was also observed that the two laminates had similar porosity (∼4%). The decrease in mechanical properties of the prepreg was attributed to the increase in resin content of the laminate.

Air quality monitoring of any specific location is important for continuous improvement of air quality and protecting public health. We demonstrate the design and development of an autonomous copter-type air quality monitoring drone to measure the amount of CO2 and CO present in the ambient air of any desired trajectory. We also measured the temperature, pressure, and humidity of the surrounding air. The proposed low cost drone is small in size, light weight, easy to maintain, and capable of flying a long distance. In addition to autonomous control, the proposed drone can be manually controlled using a long-range remote controller. The maximum altitude of the drone from the ground control station is approximately 500 m, whereas the maximum velocity is 50 km/hour. During air quality monitoring, we collected the air quality data from 1 feet to 200 feet with 20 feet interval where the average velocity of the drone was 5.4 km/hour. We selected three different locations for data collection. Afterwards, we analyzed the collected data and determined the primary causes of variation in the CO2 and CO concentration of various locations under different altitudes. We strongly believe that, the proposed drone will be useful for collecting location specific air quality information and taking necessary actions to reduce air pollution.

More than 380,000 hips are replaced with total joint prostheses each year in the U.S. Wear debris generated by metal-on-metal implant designs is of concern due to potential adverse biological effects arising from chronic exposure of human tissue to the wear debris. This paper presents a new methodology for optimizing the wear performance of prosthesis made of Co-Cr-Mo alloys by varying tool edge geometry and machining conditions to alter the wear behavior of this alloy, while also controlling the residual stresses induced during the machining process. The machining process causes inhomogeneous inelastic deformations near the surface layer of machined parts which create residual stresses in the surface of machined components. Residual stresses in the machined surface and the subsurface are affected by cutting tool material, tool geometry, workpiece, tool-work interface conditions, and the cutting parameters such as feed rate, depth of cut and cutting speed. In the current work, residual stresses were measured using X-ray diffraction technique (XRD). The surface residual stresses in two directions (radial and hoop) were measured on the machined pins after machining with different machining conditions, but prior to the wear test. Wear behavior of Co-Cr-Mo alloy pin specimens, produced from machining with varying tool edge geometry and machining conditions, was studied using a custom-made biaxial motion pin-on-disc tribological testing system in which the pin specimen is immersed in a simulated bio-fluid environment. Wear-induced weight loss (± 10 μg) and changes in surface roughness (± 0.001 μm) were obtained at 100,000 cycle intervals upto 500,000 cycles. Metallographic analysis was performed on the machined pin specimens to analyze the microstructure and microhardness before and after testing. The rate of wear for the specimens was lowest for those pins where the change of the subsurface microhardness was small due to prevention of additional steady state wear after the initial run-in wear in the wear tester. A combination or response surface methodology and genetic algorithm (GA) was used in to optimize the various machining parameters for minimized wear generation. The optimal combination of the four machining parameters (feed 0.18mm/rev, nose radius 0.6 mm, cutting speed 27.6 m/min and depth of cut 0.38) produced the largest compressive residual stresses on the surface and subsurface of the implants thereby reducing the wear/debris generation by about fifty percent.

Digital transformation processes in the course of industry 4.0 affect computer-aided manufacturing (CAM) in two ways: The acceleration of production and innovation cycles shortens the time to carry out CAM-planning tasks; simultaneously, an increasing product individualization raises the complexity of CAM-planning tasks and quality requirements for the planning results. Thus, CAM users need to solve complex CAM-planning tasks in increasingly shorter time frames. Efforts to meet the quality requirements nonetheless lead to overload and frustration of the user [1], [2]. To overcome this challenge, the R&D project CAM2030 aims to develop a new generation of CAM systems that integrates innovative technologies (artificial intelligence, cloud computing, and evolutionary algorithms) to make CAM-planning processes more efficient for the CAM planner. The innovation process requires a novel methodology that involves the stakeholders’ different perspectives, esp. the users’ preferences and needs, and brings them into compliance. This paper presents a co-creation-based framework for the agile development of AI-supported system components. The framework intends to continuously support the innovation process of complex software systems in a highly interdisciplinary team working collaboratively under remote conditions. The framework was developed successively in line with the project’s progress over two years. The resulting framework describes a multi-level and partly iterative approach that covers the following stages of the innovation process: (i) the elicitation, specification, and prioritization of requirements for AI-supported CAM systems, their user interface, and CAM user training; (ii) the design of an interactive prototype for selected parts of the user interface; (iii) the prototype testing; and (iv) the iteration of (i) to (iii) as well as the refinement of their output. The approach applies and adapts co-creation methods for use in online workshops. The research activities focused on the development, implementation, and evaluation of the single workshop concepts, partly complemented by studies investigating topics such as user expectations and requirements concerning new features and the system introduction. The main characteristics of the workshops are their interdisciplinary composition of participants, their conduction under remote conditions, and the mix of methods and tools to support collaboration in each stage of the innovation process [3], [4].The framework application shows a high potential to support the development of AI-supported CAM systems in creating a shared vision of the individual stages of the innovation and the innovation process as a whole. The framework helps to: (i) understand and reflect the user’s needs and preferences, (ii) align different and partly controversial perspectives, and (iii) identify and overcome sticking points of the system development. The project shows that the innovation and development process benefits from the active involvement of end users (workers and companies), the continuity of interdisciplinary exchange, and iterative testing. Limitations arise from the restricted application scope of the framework (innovating automated CAM system components for the CAM parameter optimization by well-educated CAM planners in German SMEs). Future research should consider the reconciliation of innovation processes with day-to-day business in manufacturing companies and the framework’s transferability to other application contexts.

<div class="section abstract"><div class="htmlview paragraph">Brake pad is considered to be the most essential part of the vehicle. Owing to environmental requirements, natural materials are the raising alternative sources for manufacturing degradable specimens. The main intern of this work was to study the tribological properties of carbon fibre with Cashew Nut Shell Liquid (CNSL) resin, Cashew Nut Shell (CNS) filler, nano Silicon dioxide (SiO<sub>2</sub>), alumina and graphite. Four samples of varying composition were prepared under optimum process parametric conditions using compression moulding machine. The prepared samples are taken for tribometer test using pin-on-disc apparatus at room temperature. In this load of 10,20,30,40N and sliding distance of 1000,2000 m are applied and responds like wear rate and co-efficient of friction were noted. In addition, the comparisons of hardness of the specimens before and after the tribometer test were also made to note the behaviour of specimens after exposure to thermal and loaded condition. The sample of 40wt% CNSL resin, 35wt% of Carbon fiber and 10wt% of CNS filler with fixed 10 wt. % of SiO<sub>2</sub>, 3 wt. % of Al<sub>2</sub>O<sub>3</sub> and 2wt.% graphite shown lesser wear rate and improved coefficient of friction. Hence frictional material of this composition will be a better choice for replacing the conventionally used organic and non-organic brake pad material.</div></div>

Abstract Manufacturing of MnCo2O4 spinel coatings by solution precursor plasma spraying (SPPS) was studied in order to produce thin ceramic coating on a ferritic stainless steel interconnect for SOFC’s. The main purpose to use MnCo2O4 coating in SOFC devices is to prevent the migration of harmful CrO3 and Cr2(OH)2 compounds to the triple phase barriers (TPB) of the cathode. In this study Mn(NO3)2•4H2O and Co(NO3)2•6H2O were diluted to deionized water and mixture of deionized water and ethanol at 3 M mixture rate. The solutions were sprayed on 0.5 mm thick Crofer 22 APU substrate by Sulzer Metco F4-MB plasma gun with a modified solution feeder. Microstructural characterizations for the as-sprayed coatings were done by using a field-emission scanning electron microscopy (FESEM) with SE-mode. Elemental analyses were done with energy dispersive spectroscopy (EDS) and an X-ray diffraction (XRD) was used for crystallographic studies. The coating with full equivalence of the crystallographic structure of MnCo2O4 spinel was sprayed using argon-helium plasma and water based solution. Plasma gas with hydrogen as a secondary or ternary gas and ethanol based solutions caused the formation of the mixed phases of CoO and MnCo2O4. Although the microstructures of sprayed coatings were still quite porous, the influence of relevant gun and solution parameters were found in order to improve coating denseness in further studies.

A rainbow field test sponsored by the Electric Power Research Institute (EPRI) under contract RP 2465-1 was performed to evaluate the comparative hot corrosion resistance of commercially available coatings for gas turbine blades and vanes. A 10,307-hr field test was carried out on a Solar Centaur T-4000 gas turbine operating on a lower grade liquid fuel at the Owens-Illinois, Inc. glass manufacturing facility in Valera, Venezuela. This paper reviews the results of an evaluation of the performance of a simple aluminide, a Pt, Rh-aluminide and two MCrAlY (M = Co, NiCo) overlays applied to the first stage FSX-414 vanes. As found for blade coatings, on the basis of visual and metallographic examination, and remnant coating thickness measurements, it was established that the MCrAlY coatings were generally more effective than the simple aluminide and the Pt, Rh-aluminide in providing protection to first stage vanes. A remnant coating thickness index (RCTT) was used to express coating survival and protectiveness quantitatively. The results of the study have been compared with literature.
