TL;DR: In this paper, the least square support vector regression-based algorithm was used to localize impact event in terms of $X$ - and $Y$ -coordinates and its energy on a CFRP plate-like structure and its comparison with other algorithms cited in the literature.
Abstract: Low-velocity impact (LVI) events in carbon fiber reinforced plastic (CFRP) structures are a major concern as they result in barely visible impact damage which can reduce the strength and stiffness of impacted structure. Detection of such impact events in terms of location and severity will be a significant milestone for aerospace structural health monitoring applications. This can result in well-targeted inspection programs thereby reducing the time and cost of periodic inspections. One of the easy and efficient ways of getting the impact response of a structure is through strain measurement. LVI event monitoring using fiber Bragg grating sensors has evolved as an attractive choice in recent years along with various soft computing algorithms and advanced signal processing techniques. Machine learning techniques such as artificial neural networks and support vector machine are widely used to localize impact events. Getting information regarding the ensuing damage due to LVI event from the strain response is not straight forward as it could involve estimation of intermediate parameters like energy/force of impact, which are further related with probable damage size. This paper demonstrates least square support vector regression-based algorithm to localize impact event in terms of $X$ - and $Y$ -coordinates and its energy on a CFRP plate-like structure and its comparison with other algorithms cited in the literature.

TL;DR: In this article, a review of the electrospinning process for the preparation of nanofibers and their possible applications is presented. But, the authors do not discuss the application of electro-spinning for the extraction of nanomaterials.
Abstract: Nanofibers are solid-state linear nanomaterials with diameters 1000 and are characterized by high surface area to volume ratio. Nanofibers, due to their high surface area to volume ratio are potential candidates for a large number of applications such as separation of liquids and gases, as sensors, photovoltaic applications, insulation, ultrapurification of water, drug delivery etc. In recent years, electrospinning technique has been successfully used for the preparation of nanofibers. Initially, polymer nanofibers are prepared using this technique. Recently, this technique has also been successfully extended for the preparation of ceramic nanofibers. This paper reviews the electrospinning process, application of electrospinning process for the preparation of ceramic nanofibers and their possible applications.
