For a graph G, the irregularity and total irregularity of G are defined as irr(G)=∑_(uv∈E(G))〖|d_G (u)-d_G (v)|〗 and irr_t (G)=1/2 ∑_(u,v∈V(G))〖|d_G (u)-d_G (v)|〗, respectively, where d_G (u) is the degree of vertex u. In this paper, we characterize all ‎connected Eulerian graphs with the second minimum irregularity, the second and third minimum total irregularity value, respectively.

Vertical vibrations in railway vehicles are not only induced by track irregularity but also affected the rotation of wheelsets with small mass imbalance. It is known that excitation force generated transmitted from bogies to car bodies through longitudinal connecting members such as traction devices and yaw dampers. In this research, we first investigated influence dampers on vertical body vibr...

ESRD03 is the database collected from 21 sound effect CDs and RWCP (Sound Scene Database in Real Acoustic Environment) database for environmental sound recognition, including more than 16000 sound tracks and most of them happening in home environments. This paper introduces the database manipulation of segmenting and labeling the data manually. Firstly the tracks are categorized according to th...

For a simple graph G with no isolated edges and at most, one vertex, labeling ?:E(G)?{1,2,…,k} of positive integers to the is called irregular if weights vertices, defined as wt?(v)=?u?N(v)?(uv), are all different. The irregularity strength known maximal integer k, minimized over labelings, set ? such exists. In this paper, we determine exact value modular fan graphs.

This paper analyzes the influence of foundation deformation and variation coefficient vehicle parameters on reliability a vertical safety. Based theory stochastic analysis nonlinear vehicle–track coupled systems, combining generalized probability density evolution theory, this takes reduction rate wheel load as measurement index, considering combined effects stochasticity track irregularity, de...

BACKGROUND/PURPOSE The Irregularity Index is a measure of border irregularity from pigmented skin lesion images. The measure attempts to quantify the degree of irregularity of the structural indentations and protrusions along a lesion border. A carefully designed study has shown that the parameters derived from the Irregularity Index were highly correlated with expert dermatologists' notion of ...

In this paper we develop a method for report level tracking based on Dempster-Shafer clustering using Potts spin neural networks where clusters of incoming reports are gradually fused into existing tracks, one cluster for each track. Incoming reports are put into a cluster and continuous reclustering of older reports is made in order to obtain maximum association fit within the cluster and towa...

The objective of this work is to find the melodic line in MIDI files. Usually, the melodic line is stored in a single track, while the other tracks contain the accompaniment. The detection of the track that contains the melodic line can be very useful for a number of applications, such as melody matching when searching in MIDI databases. The system was developed using WEKA. First, a set of desc...

If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...

The HERA collider has recently been upgraded to produce a factor of approximately 5 more luminosity. In parallel, upgrades to the H1 detector and trigger have been necessary. One of the projects was the design of an improved Fast Track Trigger (FTT) which should replace the old track trigger and is based on the central drift chambers of the H1 experiment. This work describes the design and expe...
