Study of atmospheric ice accretion on a non-rotating vertical circular cylindrical object was carried out at dry and wet ice conditions. Both numerical and experimental techniques were used during this study. 3D numerical study was carried out using computational fluid dynamics based approach, whereas experimental study was carried out at Cryospheric Environmental Simulator ‘CES’ in Shinjo, Japan. ...

The problems encountered in installation, maintenance and operations of equipment in the cold climate regions are far more complicated than others. The contributing factors and problems that can affect the system operation and performance should be identified, assessed and focused within well-defined parameters before its installation in cold climate regions. The harsh cold environment, could not ...

Dissociation of passenger travel from baggage delivery has been proposed as one of the radical innovations in future air travel. This concept is still relatively new and largely unexplored, so there are many issues that need to be resolved. For instance, a complete end-to-end baggage dissociation will require the ground distribution networks to deliver passenger luggage to and from the departing ...

The purpose of this paper is to look at the indicators to which a city can be considered to be a smart city based upon the degree it meets specific indicators within the categories of ‘Social Smartness’, ‘Technological Smartness’ and ‘Environmental Smartness’. The data collection for this paper was conducted through desk research in academic and non academic articles and publications that focus on ...

With the increase of the concern from the public for environmental pollution and waste of resources, the value recovery through reuse, repair, remanufacturing and recycling from the end-of-use (EOU) and end-of-life (EOL) products have become increasingly important. Reverse logistics is the process for capturing the remaining value from the EOU and EOL products and also for the proper disposal of the ...

Application of automation in SMEs working in fish industry is not in advanced state as in other fields of production and manufacturing industries. Due to expensive equipment, high labor costs of engineers required to implement such features into production lines, and low-quantity contracts, introduction of automation technologies is in large part of these companies is absent. This paper analyses ...

Due to the unprecedentedly increasing demands of waterway transportation on the Yangtze River during the latest years, traffic congestion at the Three Gorges Dam (TGD) has becoming a serious problem. In busiest seasons, a vessel may need to wait up to 3 days for passing the TGD via the ship lift or the five-stage ship lock. In order to improve the navigation efficiency and the utilization of passing ...

The erratic modern world introduces challenges to all sectors of societies and potentially introduces additional inequality. One possibility to decrease the educational inequality is to provide remote access to facilities that enable learning and training. A similar approach of remote resource usage can be utilized in resource-poor situations where the required equipment is available at other premises. ...

With globalization and rapid technological-economic development accelerating the market dynamics, consumers' demand is becoming more volatile and diverse. In this situation, capacity adjustment as an operational strategic decision plays a major role to ensure supply chain responsiveness while maintaining costs at a reasonable norm. This study contributes to the literature by developing computationally ...

Ice accretion has been a persisting issue in cold regions and poses a threat to onshore and offshore infrastructure, especially to sensitive equipment and personnel safety. Thermal infrared imaging (thermography) can be used as a non-destructive, non- invasive technique to determine the presence and thickness of ice over a surface. The paper presents early-stage experiment results with a FLIR® Lepton ...
