Structural health monitoring for lightweight complex composite structures is being investigated in this paper with a data-driven deep learning approach to facilitate automated of the map transformed signal features damage classes. Towards this, series acoustic emission (AE) based laboratory experiments have been carried out on sample using piezoelectric AE sensor network. The registered time-do...

Active sonar target classification remains an ongoing area of research due to the unique challenges associated with problem (unknown parameters, dynamic oceanic environment, different scattering mechanisms, etc.). Many feature extraction and techniques have been proposed, but there a need relate explain classifier results in physical domain. This work examines convolutional neural networks trai...

Jakarta and Bandung metropolitan areas in Indonesia are experiencing urban expansion, which makes these two increasingly connected by corridors to become one mega-urban. Karawang Purwakarta Regencies part of the Jakarta-Bandung corridor area then triggers physical development. This study aims 1) Determine level service facilities Regencies; 2) Identify changes built-up paddy fields Land Use/Lan...

Tangerang Regency has an economic structure dominated by the industrial sector. Population distribution, settlement location and influenced land use patterns regional development levels in Regency. The objectives of this research are: to analyze level inequality factors that influence development; typology; evaluate consistency with Spatial Planning; formulate direction plan. method used are sc...

Active sonar performance is limited by noise, reverberation or false alarm rate (FAR). High FAR is overcome through the use of signal classification, which depends on the information content of the signals. Information content and classification are addressed using a set of broadband sonar echoes. The set of broadband echoes generated by an explosive source scattered from 30 different geographi...

Bearings are one of the critical components which fail often in rotating machinery during operation. Bearing faults in the mechanical system run by an induction motor causes change in its stator current spectrum. It is due to the fact that faults in the bearings cause variations of load irregularities in the magnetic field which in turn change the mutual and self inductance causing side bands a...

OBJECTIVE The aim of this study was to determine postural responses before and after a vestibular rehabilitation program (VRP) in 14 patients with central vestibular disorders (CVD). MATERIAL AND METHODS The confidence ellipse (CE) of the center of pressure distribution area and the sway velocity (SV) were the parameters used for the quantitative assessment of postural control (PC). These two...

Patients with different vestibular disorders exhibit changes in postural behaviour when they receive visual stimuli, reproducing environmental stimulation. Postural control was studied using an AMTI Accusway platform, measuring the confidential ellipse (CE) and sway velocity (SV). Postural responses were recorded according to the following stimulation paradigm: i) without specific stimuli; ii) ...

This review focuses on the analysis of temporal beta diversity, which is the variation in community composition along time in a study area. Temporal beta diversity is measured by the variance of the multivariate community composition time series and that variance can be partitioned using appropriate statistical methods. Some of these methods are classical, such as simple or canonical ordination...
