We review the construction of extended ( N = 2 and N = 4 ) superconformal algebras over triple systems and the gauged WZW models invariant under them. The N = 2 superconformal algebras (SCA) realized over Freudenthal triple systems (FTS) admit extension to “maximal” N = 4 SCA’s with SU(2)× SU(2)× U(1) symmetry. A detailed study of the construction and classification of N = 2 and N = 4 SCA’s ove...

Overview of review : This paper described the intercomparison results of methane profiles and its total column density between AIRS and GOSAT TANSO-FTS, the methane profiles were retrieved by thermal infrared spectral range of both instruments. The results showed the influence of Averaging Kernel through the comparison, it was found that the AK reduces the difference. The results also showed th...

The offshore wind industry, which aims to reduce the operational costs, usually achieved through learning curves and supply chain improvements, has seen drastic cost increase over the last five years. In order to sustain the competitiveness of the offshore wind industry against other renewable energy sources, the cost of offshore wind needs to come down to today’s onshore cost. This cost reduct...

To enhance fleet operation and management, taxi operators instrument their vehicles with GPS receivers and network connectivity to servers. Mobility traces from such large fleets provide significant information on commuter travel patterns, traffic congestion and road anomalies, and hence several researchers have mined such datasets to gain useful urban insights. The fleet companies, however, in...

The transit fleet maintenance community is positioned to make some significant advances in the new millennium. Changes in technology offer much potential for supporting both traditional management activities and some equipment capabilities that have recently become available. However, benefits will be realized only after successfully navigating some significant challenges. Ironically, the tende...

This paper presents a hybrid evolutionary algorithm (HEA) to solve heterogeneous fleet vehicle routing problems with time windows. There are two main types of such problems, namely the fleet size and mix vehicle routing problem with time windows (F) and the heterogeneous fixed fleet vehicle routing problem with time windows (H), where the latter, in contrast to the former, assumes a limited ava...

According to the demand for condition-based maintenance online decision making among a mission oriented fleet, an intelligent maintenance decision making method based on Multi-agent and heuristic rules is proposed. The process of condition-based maintenance within an aircraft fleet (each containing one or more Line Replaceable Modules) based on multiple maintenance thresholds is analyzed. Then ...

Automated material handling systems are used in healthcare facilities to optimize flow, minimize workforce requirements, reduce risk of contamination, and work injuries. This paper develops a case study using data from Greenville Memorial Hospital (GMH) South Carolina, USA. The is focused on the delivery surgical carts operating rooms at GMH via Guided Vehicles (AGVs). proposes framework that i...
