Introduction The Airline Deregulation Act (ADA) of 1978 caused many changes in the industry. For the first time in 40 years, new airlines were permitted to enter the industry, and all airlines could choose the routes they would serve and the fares they would charge. Airlines were also free to exit the industry (go bankrupt), if they made poor choices in these matters. Naturally, this has led to...

Passenger flow safety detection in high-speed railway transport hub is considered in this paper. For accurately detecting the passenger flow safety, an improved watershed algorithm and a recognition algorithm are respectively proposed in sensor-based detection process. Computational experiments on sensor data from a specific Chinese high-speed railway transport hub show that the proposed algori...

BACKGROUND & OBJECTIVES Limited studies have been reported on Japanese encephalitis (JE) with reference to microarray data analysis. The present study involved an in silico approach for identification and characterization of differentially expressed genes in human microglial cell (CHME3) samples, infected with P20778 strain of Japanese encephalitis virus (JEV). METHODS Gene expression data (G...

Low power hub motors are widely used in electromechanical systems such as electrical bicycles and solar vehicles due to their robustness and compact structure. Such systems driven by hub motors (in wheel motors) encounter previously defined and undefined faults under operation. It may inevitably lead to the interruption of the electromechanical system operation; hence, economic losses take plac...

The 4th Prof. Vijaya Agarwala Memorial National Symposium on Microwave Absorbing Materials (VAMMAM-2020)” was held during 23 - 24th, August 2020 at Indian Institute of Technology Roorkee in association with Centre Nanotechnology and Common Research Development Hub (CRTDH) for New Materials/Stealth Applications Department Applied Mechanics Motilal Nehru Allahabad, Prayagraj, India.

In this paper we present a hybrid heuristic for the capacitated pmedian problem (CPMP). This problem considers a set of n points, each of them with a known demand, the objective consists of finding p medians and assign each point to exactly one median such that the total distance of assigned points to their corresponding medians is minimized, and the a capacity limit on the medians may not be e...

Hydrocarbon Utilizing Bacteria (HUB) were isolated at the juvenile and maturity stages from the core and rhizosphere of Tianung 1, Tianung 2 and Cuba 108 accessions of Kenaf (Hibiscus cannabinus) plant grown in a hydrocarbon unimpacted soil in the Niger Delta Area. Standard culture dependent techniques were used for the enumeration of heterotrophic and hydrocarbon-utilizing bacteria while PCR a...

This paper presents an artificial bee colony (ABC) algorithm adjusted for the capacitated vehicle routing problem. The vehicle routing problem is an NP-hard problem and capacitated vehicle routing problem variant (CVRP) is considered here. The artificial bee metaheuristic was successfully used mostly on continuous unconstrained and constrained problems. Here this algorithm has been implemented ...

Study objective: Assessment of the impact of the regionalisation of cardiac surgery through the organisational form of a hub&spoke model introduced in the year 2000. Design: Case mix adjusted before (1998–1999)—after (2000–2002) comparison of: (a) in-hospital and 30 days mortality rates; (b) proportion of patients timely (within one day) referred for surgery from spoke to hub centres; (c) patie...

In this paper we report on the LIMSI 1999 Hub-4E system for broadcast news transcription. The main difference from our previous broadcast news transcription system is that a new decoder was implemented to meet the 10xRT requirement. This single pass 4-gram dynamic network decoder is based on a time-synchronous Viterbi search with dynamic expansion of LM-state conditioned lexical trees, and with...
