## Abstract The present paper proposes a novel design of a Wilkinson power splitter, which utilizes the nonlinear dispersion characteristic of a leftβhanded transmission line (LHTL). The proposed device has been fabricated using the lumped LβC βΞ»/4 LHTLs instead of the conventional TLs to implement

β¦ Synopsis
The paper addresses the issue of selection of diagnostic parameters and methods of an object's condition classification. The research was conducted for a power transmission unit of a commuter train. We analysed the vibration of the axle box as measured on the track for systems before and after an overhaul. In the final part of the paper, we proposed an algorithm that can be used to identify the technical condition of a machine while using neural networks and we also described the operation of an on-line diagnostic system.

## Abstract Realβtime monitoring of wastewater quality remains an unresolved problem to the wastewater treatment industry. In order to comply with increasingly stringent environmental regulations, plant operators as well as instrument manufacturers have expressed the need for new standards and impr
Near infrared (NIR) spectroscopy has been used in a noninvasively mode to develop qualitative and quantitative methods for the monitoring of a wet granulation process. The formulation contained API (10%w/w) and microcrystalline cellulose and maize starch as main excipients. NIR spectra have been acq
