This paper proposes the full simulation model for electrical analysis of all-electric ship (AES) based on a medium voltage DC power system. The AES has become popular both in commercial and military areas due to low emission, high fuel consumption efficiency, wide applicability. In spite many advantages, it is complex difficult construct whole system with mechanical components onboard. Full ess...

The purpose of this study was a techno-environmental assessment analysis for 280,000 m3 liquid hydrogen (LH2) tanker powered by hydrogen-fuelled combined-cycle gas turbine (COGAS) as the prime mover. This utilised established and reliable methods to simulate LH2 in different journeys conditions analysing advantages COGAS terms performance emission reduction. based on engine behaviour under carg...

Bed pushing during patient transfer is one of the most physically demanding and yet common tasks in the hospital setting. Powered bed movers have been increasingly introduced to hospitals to reduce physiological strains on the users. This study introduces and quantifies the manpower efficiency and health benefits of a novel robotic-assisted omni-directional hospital bed transporter (SESTO Bed M...

This study presents a combined cooling, heating, and power system powered by biogas, suitable for small scale communities in remote locations. To run such system, order to obtain the daily life essentials of electricity, hot water, municipal waste can be considered as an option. Furthermore, organic Rankine cycle part vapor compression chiller used times need additional electric production. The...

This research examined the effects of timing, order and the durability of first mover advantages by analyzing the stock market reactions to new product introductions and imitations. The major findings are that both timing and order of moves are important and that rival reactions undermine the durability of first mover advantages. More specifically, (1) early and fast movers achieve greater gain...

We offer a new algorithm for analyzing innovation timing games. Its main advantage over the traditional approach is that it applies to problems that had previously been intractable. We use the algorithm to examine two classical innovation problems. We find that the competition takes the form of a waiting game with a second-mover advantage either for any level of R&D costs (process innovation) o...

In this note we present a proof that the variation distance up to relabeling is upperbounded by the “relative earth mover distance” (to be defined below). The relative earth mover distance was introduced by Valiant and Valiant [VV11], and was extensively used in their work. The foregoing claim was made in [VV11], but was not used there. The claim appears a special case of [VV15, Fact 1] (i.e., ...
