TL;DR: In this article, a comparison of the engine performance and exhaust emission on a gasoline and compressed natural gas (CNG) fueled retrofitted spark ignition car engine was performed using a computer-based data acquisition and control system.

TL;DR: In this article, a comprehensive and up-to-date review of the existing literatures on manufacturing under uncertain conditions is presented, where the authors have identified the various sources and factors of uncertainty in manufacturing/production environment and adjusted the focus on the techniques and models used to tackle the storms.

TL;DR: In this paper, a solar air heater is designed, fabricated and its performance is assessed in the perspective of an emerging/developing country with a huge energy demand like Bangladesh, where the shortness of winter days can be compensated by reducing the heat loss during long nights.

TL;DR: In this paper, an in-depth scenario and analysis of the micro hydro energy in Bangladesh is presented, which represents a look into a time tested, yet underused technology driven by water.

TL;DR: In this paper, an experimental investigation has been carried out for turbulent flow in a tube with perforated twisted tape inserts, and the results showed that the insertion of twisted tape in a circular tube enhanced the heat transfer rate with an increase in friction factor and pumping power.
