In data transmission networks, the feasibility of data transmission can be characterized by the existence of fractional factors. If some channels and stations are not available in the transmission network at the moment, the possibility of transmission between data is characterized by whether the corresponding graph structure of the network is critical deleted. Toughness used to measure the vulnerability and robustness of a network, which is an important parameter to be considered in network designing. In this paper, we mainly study the relationship between toughness and the all fractional critical deleted graph, and a toughness condition for a graph to be all fractional (g,f,n)-critical deleted is determined.

Abstract In data transmission networks, the availability of data transmission is equivalent to the existence of the fractional factor of the corresponding graph which is generated by the network. Research on the existence of fractional factors under specific network structures can help scientists design and construct networks with high data transmission rates. A graph G is named as an all fractional (g, f, n′, m)-critical deleted graph if the remaining subgraph keeps being an all fractional (g, f, m)-critical graph, despite experiencing the removal of arbitrary n′ vertices of G. In this paper, we study the relationship between neighborhood conditions and a graph to be all fractional (g, f, n′, m)-critical deleted. Two sufficient neighborhood conditions are determined, and furthermore we show that the conditions stated in the main results are sharp.

Data security is very important in the multi-path transmission networks (MTN). Efficient data security measurement in MTN is crucial so as to ensure the reliability of data transmission. To this end, this paper presents an improved algorithm using single-single minimal path based back-up path (SSMP-BP), which is designed to ensure the data transmission when the second path is out of work. From the simulation study, the proposed algorithm has the better network reliability compared with existing double minimal path based backup path (DMP-BP) approach. It could be found that, the proposed algorithm uses less back-up paths compared with DMP-BP so that less network resources like nodes are achieved.

The publication deals with the design and modeling of fault tolerance for secured software-defined data transmission networks. A technique for evaluating the parameters of fault tolerance of a software-defined data transmission network is proposed. An organizational model for building a software-configurable data transmission network based on the design of a configuration based on the principle of dynamic protection with the use of selective transformation, taking into account the probability of failures and allowing to ensure high specified parameters of fault tolerance.

IntroductionThe relationship between parents and children is a complex link. In the process of pregnancy-birth-puerperium, frequent feelings such as responsibility, love, fear, uncertainty, generate strong expectations at birth. The death of a newborn may not be perceived as natural by the parents, considering the local culture and the context of great technological development of neonatology.ObjectiveTo explore possible guilt and fantasies in life experiences of parents during mourning process due to death of their newborn.MethodClinical-qualitative design, a particularization of qualitative methods here applied in clinical assistance settings with highlight to psychological aspects. Data collection with the technique of semi-directed interview with open-ended questions, in-depth. Sample intentionally constructed, with closure by theoretical saturation of information. The participants were 7 parents, mourning by the death of their child at the neonatal intensive care unit, in a university hospital of Campinas, São Paulo State.ResultsFeelings of guilt - conscious or not - lead to an internal and particular movement so that mourning can be lived. The participants showed certain embarrassment, accompanied by natural suffering facing to the cultural pattern that permeates the emotional experience. It predicts types of psychological meanings that the experience will give to the person.ConclusionHealth professionals working with bereaved parents should consider more deeply the moment these one experienced, with emphasis on the details of the death scenery, beside the problems of illness and death properly so called.Disclosure of interestThe authors have not supplied their declaration of competing interest.

In this article, Victoria Hunter explores the concept of the ‘here and now’ in the creation of site-specific dance performance, in response to Doreen Massey's questioning of the fixity of the concept of the ‘here and now’ during the recent RESCEN seminar on ‘Making Space’, in which she challenged the concept of a singular fixed ‘present’, suggesting instead that we exist in a constant production of ‘here and nows’ akin to ‘being in the moment’. Here the concept is applied to an analysis of the author's recent performance work created as part of a PhD investigation into the relationship between the site and the creative process in site-specific dance performance. In this context the notion of the ‘here and now’ is discussed in relation to the concept of dance embodiment informed by the site and the genius loci, or ‘spirit of place’. Victoria Hunter is a Lecturer in Dance at the University of Leeds, who is currently researching a PhD in site-specific dance performance.

In this paper, in order to achieve real-time remote monitoring of fire site, we designed a intelligent remote fire monitoring system based on ZigBee network and GPRS network. This system, used ZigBee and sensor to build data acquisition and short distance transmission network and combined with GPRS wireless data transmission and SMS alarm ,cooperates with the server and PC to build a remote monitoring scheme based on GRPS.

The relationship between parameters extracted from the musical stimuli and emotional response has been traditionally approached using several physical measures extracted from time or frequency domains. From time-domain measures, the musical onset is defined as the moment in that any musical instrument or human voice issues a musical note. The onsets’ sequence in the performance of a specific musical score creates what is known as the onset curve (OC). The influence of the structure of OC on the emotional judgment of people is not known. To this end, we have applied principal component analysis on a complete set of variables extracted from the OC to capture their statistical structure. We have found a trifactorial structure related to activation and valence dimensions of emotional judgment. The structure has been cross-validated using different participants and stimuli. In this way, we propose the factorial scores of the OC as a reliable and relevant piece of information to predict the emotional judgment of music.
