    A coupled artificial neural network and RSM model for the prediction of chip serration frequency in end milling of Inconel 718 by Patwari, Muhammed Anayet Ullah, Amin, A. K. M. Nurul, Ishtiyaq, M. H.

    Published 2011
    “…They found that chatter arising during turning is a result of resonance, caused by mutual interaction of the vibrations due to serrated elements of the chip and the natural vibrations of the system components, e.g. the spindle and the tool holder [2-3]. Komanduri [4-5] has made some remarkable progress in the research of chip segmentation and instability in chip formation. …”

    An investigation on the performance of a single cylinder diesel engine using biodiesel by Uddin, Md. Nasir, Rashid, Muhammad Mahbubur, Nithe, N. A., Rony, J. I.

    Published 2016
    “…The thermal performance and emissions characteristics are evaluated by operating the engine at different preset compression ratios (CRs) of 14, 15, 16, 17, 17.5 and 18, different injection pressures (IPs) of 150 bar, 200 bar and 250 bar and varying loads from 0kg to 12 kg in steps of 3kg.The thermal performance parameters evaluated are brake thermal efficiency (BTHE), brake specific fuel consumption (BSFC), brake mean effective pressure (BMEP), volumetric efficiency, heat equivalent of brake power (HBP), heat with exhaust gas (HGas) and exhaust gas temperature (EGT). …”
