This paper presents a novel approach to the detection and recognition of faulty audio signalling devices as part of an automated industrial manufacturing quality assurance process. The proposed system outperforms other well-established automated systems based on mel-frequency cepstrum coefficients (MFCC) and multi-layer perceptron (MLP). It uses both unlabelled sound data and labelled historica...

Objective: To investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic Parkinson’s disease (PD). Materials and methods: In this cross-sectional study, 55 patients with idiopathic PD by mean age of 59.85 ± 11.89 years, and mean Hoehn and Yahr stage ...

The use of carbon composites has continuously increased in the commercial aircraft industry due to more challenging weight targets which is one way to handle the environmental requirements to lower the CO2 emissions. One type of aircraft structure component made at Saab Aerostructures is long and slender U-sections manufactured in carbon composites. The manufacturing is performed by manual layu...

A linear axis is a vital subsystem of machine tools, which are vital systems within many manufacturing operations. When installed and operating within a manufacturing facility, a machine tool needs to stay in good condition for parts production. All machine tools degrade during operations, yet knowledge of that degradation is illusive; specifically, accurately detecting degradation of linear ax...

Virtual manufacturing (VM) has been studied in various activities of manufacturing. The objectives of the studies depend on the nature of investigation: ranging from optimization of product and process design, workplace design, simulation of plant operation and layouts, to improvement of manual operations in ergonomic studies. VM helps to shorten the product development process by its ability o...

Silica nanoparticles (SNPs) are widely used all around the world and it is necessary to evaluate appropriate risk management measures. An initial step in this process is to assess worker exposures in their current situation. The objective of this study was to compare concentrations and morphologic characteristics of fumed (FS) and sol-gel silica nanoparticles (SS) in two manufacturing facilitie...

Wire harness manufacturing in the aeronautic sector is highly manual work, with production defined by multiple references and small batches. Although complete automation of process not feasible, a robot-assisted approach could increase efficiency existing means. This paper presents novel dual-arm robotic solution for workbench configuration cable routing during initial steps wire manufacturing....

It is a common practice in biotherapeutic manufacturing to define a fixed-volume feed strategy for nutrient feeds, based on historical cell demand. However, once the feed volumes are defined, they are inflexible to batch-to-batch variations in cell growth and physiology and can lead to inconsistent productivity and product quality. In an effort to control critical quality attributes and to appl...

Cable wound electric machines are used mainly for high voltage and direct-drive applications. They can be found in areas such as wind power, hydropower, wave power and high-voltage motors. Compared to conventional winding techniques, cable winding includes fewer manufacturing steps and is therefore likely to be better suited for automated production. Automation of the cable winding production s...

original article   health, safety, and environment management are dedicated a vast area in which ergonomics aspects known as one of the related aspects. in the following case study, the occupational hygiene by ergonomic intervention is focused. one of the prevalent activities among industrial sectors' workers in the developing countries is manual lifting tasks and other related physical activit...
