Abstract

Purpose

The paper aims to introduce an intelligent recognition system for viewpoint variations of gait and speech. It proposes a convolutional neural network-based capsule network (CNN-CapsNet) model and outlining the performance of the system in recognition of gait and speech variations. The proposed intelligent system mainly focuses on relative spatial hierarchies between gait features in the entities of the image due to translational invariances in sub-sampling and speech variations.

Design/methodology/approach

This proposed work CNN-CapsNet is mainly used for automatic learning of feature representations based on CNN and used capsule vectors as neurons to encode all the spatial information of an image by adapting equal variances to change in viewpoint. The proposed study will resolve the discrepancies caused by cofactors and gait recognition between opinions based on a model of CNN-CapsNet.

Findings

This research work provides recognition of signal, biometric-based gait recognition and sound/speech analysis. Empirical evaluations are conducted on three aspects of scenarios, namely fixed-view, cross-view and multi-view conditions. The main parameters for recognition of gait are speed, change in clothes, subjects walking with carrying object and intensity of light.

Research limitations/implications

The proposed CNN-CapsNet has some limitations when considering for detecting the walking targets from surveillance videos considering multimodal fusion approaches using hardware sensor devices. It can also act as a pre-requisite tool to analyze, identify, detect and verify the malware practices.

Practical implications

This research work includes for detecting the walking targets from surveillance videos considering multimodal fusion approaches using hardware sensor devices. It can also act as a pre-requisite tool to analyze, identify, detect and verify the malware practices.

Originality/value

This proposed research work proves to be performing better for the recognition of gait and speech when compared with other techniques.

Abstract

Purpose

Aluminum alloys are applicable in marine and aero fields. Alloys AA5083 and AA6061 are aluminum alloys with different chemical and physical properties. Combination of two dissimilar materials could result in enhanced strength. Generally, dissimilar aluminum alloy joint is made by friction stir welding (FSW) to achieve improved physical properties compared with the parent alloys. The purpose of this research is to develop a new FSW dissimilar material with enhanced properties using AA5083 and AA6061 alloys.

Design/methodology/approach

In this research, FSW joint was made for butt joint configuration using AA5083 and AA6061 aluminum alloys. Cylindrical pin with threaded profile was used to perform the joint. The tool tilting angle was maintained as constant, and the tool rotational speed and the welding speed were varied. Wear performance and mechanical strength of the joint were analyzed.

Findings

The results revealed that the increase of tool rotational speed led to poor wear performance, whereas increase of welding speed showed a better wear performance. Further, the prepared joint was analyzed for different wear parameters such as sliding velocity and applied load. The results displayed that the increase of sliding velocity exhibited low wear rate and the increase of load showed high wear rate.

Originality/value

This work is original and deals with the wear performance of AA5083–AA6061 joint at different tool rotational and welding speeds.

Abstract

Purpose

This paper aims to analyze spray characteristics of rapeseed oil as a cutting fluid in minimum quantity lubrication (MQL) through numerical simulation.

Design/methodology/approach

Computational fluid dynamics (CFD) is used in this numerical study. The Eulerian–Lagrangian approach was used in this simulation to project trajectories of the droplets as the cutting fluid is dispersed into a continuous phase, i.e. air. The spray characteristics of the multiphase fluids were obtained numerically using the discrete phase model (DPM).

Findings

The spray characteristics such as particle diameter and velocity were obtained for various pressure level, flow rate and nozzle diameter. The particle diameter decreased with increased pressure, whereas the velocity increased with increased pressure, flow rate and nozzle diameter. The changes in particle diameter are insignificant with respect to flow rate and nozzle diameter. DPM is an effective tool for machining processes to determine the behaviour of different cutting fluids under the MQL system.

Originality/value

In this study, the droplet and velocity distribution of vegetable oil, i.e. rapeseed oil, was investigated at the different air pressure, flow rate and nozzle diameter. This study will give insight for the manufacturer to select the better MQL system parameters to reduce the cost, time of machining processes and enhance the sustainability of the process.

Abstract

Purpose

The purpose of this paper is to provide sector-specific empirical evidence on the comparative evaluation of total productive maintenance (TPM) and total quality management (TQM) approaches, implemented exclusively and collectively on improving manufacturing business performance.

Design/methodology/approach

This paper develops a multi-sector analysis framework to comparatively assess the synergistic and standalone effect of TPM and TQM improvement approaches. A total of 231 manufacturing organizations from food and beverages, textiles and electrical and electronics sectors have been extensively surveyed. These firms were further clustered into TPM focus, TQM focus and integrated TPM×TQM on the basis of their primary manufacturing strategy. Comparative assessment of these three manufacturing approaches has been evaluated using t-test statistics.

Findings

This paper highlights that adoption of integrated TPM×TQM approach is beneficial for food and beverages and electrical and electronics sectors. However, this supposition is rejected for firms operating in the textile sector.

Research limitations/implications

The findings of this research are still exploratory. Future research using countrywide and cross-country approach can be undertaken to statistically generalize the findings of the present research. In-depth case studies are needed to further validate the findings of the study empirically.

Practical implications

The result of this study help managers and practitioners to make manufacturing strategic decision based on the nature of their operating business sector regarding adoption of TPM and TQM practices, which will further revive their firm’s competitiveness.

Originality/value

Every operating sector embraces a diversity of manufacturing activities based upon their competing priorities. This paper makes an attempt to present a multi-sectoral evaluation of joint implementation and effect of manufacturing programs.

Waste production and related environmental problems have caused urban services management many problems in collecting, transporting and disposal of waste. The purpose of this study is to design a new model for municipal waste collection vehicle routing problems with time windows and energy generating from waste. To this purpose, a bi-objective model is presented with the objectives of increasing the income of waste recycles and energy generation from waste and reducing emissions from environmental pollutants.

Design/methodology/approach

A bi-objective model is presented with the objectives of increasing income of recycles trade and energy generation and reducing emissions from environmental pollutants. Concerning the complexity of the model and its inability to solve large-scale problems, non-dominated sorting genetic algorithms and multi-objective particle swarm optimization algorithms are applied.

Findings

In this research, an integrated approach to urban waste collection modeling that coordinates the various activities of waste management in the city of Kermanshah and energy generation from waste are provided. Besides, this study calculates the criteria that show the environmental effects of municipal waste. The proposed model helps to collect municipal wastes in the shortest possible time in addition to reducing the total cost, revenues from the sale of recycled materials and energy production.

Originality/value

The proposed model boosts the current understanding of the waste management and energy generation of waste. The paper adds additional value by unveiling some key future research directions. This guidance may demonstrate possible existing and unexplored gaps so that researchers can direct future research to develop new processes.

Abstract

Purpose

Waste production and related environmental problems have caused urban services management many problems in collecting, transporting and disposal of waste. Since collecting and transporting waste are important parts of waste management budget, it is necessary to apply an appropriate method to reduce costs of collection. The aim of this study is to design a new model for urban waste collection vehicle routing problem with time windows and energy generating from waste.

Design/methodology/approach

A multiobjective model is presented with the objectives of minimizing cost of waste collection, reducing emissions from environmental pollutants and increasing income of recycles trade and energy recovery. Concerning the complexity of the model and its inability to solve large-scale problems, hyperactive genetic algorithms and multiple objective particle swarm optimization are applied.

Findings

The proposed model not only affects costs and income but also reduces the emissions of environmental pollutants. To solve the formulated model, multitarget approaches are applied on the processing site of Kermanshah city as a case study. The solutions of these algorithms and the exact method of partial constraints are compared and the outcomes are verified by numerical analysis by solving various examples in small, medium and large scales. The proposed model helps to collect urban wastes in the shortest possible time in addition to reducing the total cost, revenues from the sale of recycled materials and energy generation.

Research limitations/implications

Waste collection is related to VRP issue. Considering the environmental requirements in waste management, the concept of green supply chain is approached. This study provides a better understanding of urban waste management by examining various articles and combining economic and environmental dimensions. Waste management with a green approach and energy production from disposable waste involves many common stakeholders.

Practical implications

This study suggests that proper waste management can generate revenue from municipal waste. Moreover, it reduces cost of collecting and emission of environmental pollutants. These findings could motivate companies to waste management with a sustainable approach.

Originality/value

The proposed model boosts the current understanding of the waste management and energy generation of waste. The paper adds additional values by unveiling some key future research directions. This guidance may demonstrate possible existing and unexplored gaps so that researchers can direct future research to develop new processes.

Abstract

Purpose

The purpose of this paper is to explore the association between ISO 9000 certification and business performance for small-to-medium enterprises in the food and beverage (F&B) industry.

Design/methodology/approach

The research employed a qualitative approach based on case studies to investigate in depth how companies perceive ISO 9001. More specifically, four enterprises were examined, and a total of 26 semi-structured in-depth interviews were conducted with top and middle managers from the companies. Questions were validated by experts and through pilot interviews. In total, 45 documents of a broad range related to the quality management system were examined. Personal observation and non-structured consultation with personnel were also used to evaluate the possible impacts and livelihood outcomes.

Findings

Research findings showed that the certified companies in the F&B industry gain a number of both internal and external benefits, including: quality awareness, increased productivity, increased personnel participation and efficiency, improved image and penetration into new markets. Regarding the financial benefits of certification, the findings are not as convincing, as one company reported no financial benefits, and the rest reported that financial benefits are indirect and intangible. Conclusively, it can be said that SMEs that wish to pursue certification should certainly expect benefits.

Practical implications

Although many studies have concentrated on analyzing the impact of the implementation of ISO 9001 certification, there is still a clear need for research in specific sectors. Practicing managers and researchers will be able to examine findings in order to evaluate benefits and weaknesses from certification, thereby identifying and acting before and after certification.

Originality/value

Although the F&B industry has shown a great preference for the ISO 9000 standard and has adopted it extensively, scant empirical evidence has been recorded on the subject. This paper contributes to a better understanding of the benefits for implementing the ISO 9001 certification and to the analysis of its application to the ever-important F&B industry in Greece, a country whose economy is particularly supported by SMEs and has been severely hit by the economic crisis. Researchers will therefore further their knowledge, understand benefits but also acknowledge weaknesses.

Abstract

Purpose

The purpose of this paper is to improve production effectiveness of equipment by facilitating the implementation of the key principles of total productive maintenance (TPM).

Design/methodology/approach

A sequential TPM-based scheme consisting of 13 procedural steps is proposed. The steps cover the basic aspects of a generic improvement system, i.e. planning, implementation, checking, corrective action and control.

Findings

The proposed scheme was effective in increasing the overall equipment effectiveness by 62.6 percent over a nine-month period only. This was a direct reflection of improvements in equipment availability, efficiency and product quality. A positive feedback regarding the smooth implementation of the scheme was also received from the responsible maintenance staff.

Research limitations/implications

The proposed scheme is intended mainly to the manufacturing industrial sector, which utilizes failure-prone equipment in running operations.

Originality/value

This study presents an original scheme that tries to avoid the many barriers of success frequently encountered during the implementation of TPM schemes, as reported in the literature. This scheme is unique in integrating between 5S and safety, health and environment initiatives, by capitalizing on the close relation between the two initiatives, and simplifying procedures for measuring how well the two initiatives are implemented in an organization in one score card. Different from previous studies, the scheme treats both “education and training” and 6S as a foundation to the core TPM principles.
