Abstract:

Most studies on human–structure interactions have focused on vertical coupling, which refers to the interaction between human bodies and structures in the vertical direction. This study, however, analyzes horizontal coupling. Several experiments on mass–structure and human–structure systems were conducted, and two horizontal-coupling human–structure models are proposed. The experimental results indicate that a stationary human body should not be regarded as a simple mass. As the number of individuals increases, the horizontal self-resonance frequency gradually decreases by approximately 0.2–0.

Abstract:

Crowd flow prediction is an essential task benefiting a wide range of applications for the transportation system and public safety. However, it is a challenging problem due to the complex spatio-temporal dependence and the complicated impact of urban structure on the crowd flow patterns. In this article, we propose a novel framework, 3- D imensional G raph C onvolution N etwork (3DGCN), to predict citywide crowd flow. We first model it as a dynamic spatio-temporal graph prediction problem, where each node represents a region with time-varying flows, and each edge represents the origin–destinat

Abstract:

Human crowd behavior is an intriguing example of collective behavior where global dynamics emerge from interindividual interactions. Although most studies of human crowds assume that all individuals are independent, the presence and impact of social groups, such as friends or families, have recently been explored. Spatial structures resulting from group behavior and decision-making processes are key aspects of social groups, and how such structures are formed and the impact of these are largely unknown, especially in the scenario of crowd evacuations. Here we experimentally show that in the vi

Abstract:

This paper presents a revisiting, with developments, of the so-called kinetic theory for active particles, with the main focus on the modeling of nonlinearly additive interactions. The approach is based on a suitable generalization of methods of kinetic theory, where interactions are depicted by stochastic games. The basic idea consists in looking for a general mathematical structure suitable to capture the main features of living, hence complex, systems. Hopefully, this structure is a candidate towards the challenging objective of designing a mathematical theory of living systems. These topic

The vibration caused by human excitation has become a key factor at the structural design stage of large-span structures including footbridges, sport stadia, and high-rise buildings. As the structures tend to become slenderer and lighter, the mass of the crowd is not negligibly small compared with the mass of the structure. In such cases, the crowd and the structure form a coupling system through a mechanism known as human–structure interaction (HSI).

Abstract:

PurposeThe purpose of this paper is to examine the presumed role played by foreign direct investment (FDI) in transferring technology from home country into a host country. This paper uses data from Albanian manufacturing industry; first, to examine whether foreign presence results in technology transfer and, if yes, what type of technology is more prevalent and to what extent? Second, the paper attempts to investigate the purported determinants of technology transfer.Design/methodology/approachThe paper uses two main methodological approaches; first, the technology transfer was determined usi

Abstract:

Parallels between the dynamic response of flexible bridges under the action of wind and under the forces induced by crowds allow each field to inform the other. Wind-induced behaviour has been traditionally classified into categories such as flutter, galloping, vortex-induced vibration and buffeting. However, computational advances such as the vortex particle method have led to a more general picture where effects may occur simultaneously and interact, such that the simple semantic demarcations break down. Similarly, the modelling of individual pedestrians has progressed the understanding of h

Abstract:

A cable-stayed bridge model under crowd excitation is established in this paper by considering the geometric nonlinear property of the cables. Lateral vibrations of the model are investigated by employing the center manifold theory, and the first-order approximation solution of the periodic vibration of the bridge is derived by using the energy method. Numerical simulations are carried out to verify the validity of our analytical expressions. Our research shows that the existence of the cables can reduce the amplitude and frequency of the bridge, especially for the large amplitude case. This m

Abstract:

In this paper, based on a multi-layer network consisting of a social network and a physical contact network, we propose a microscopic Monte Carlo simulation model to reproduce the interaction and spread phenomena in the crowd from complex network perspective. The model mainly is used to reproduce the epidemic spread in the situation that the crowd becomes panic showing preventive control behaviors. This coupled microscopic simulation model considers variable infectious rate, recovery rate, panic heterogeneity and preventive measures suitable for studying different actual scenarios. Under the p

Abstract:

Abstract The added-damping effect of human-structure interaction (HSI) is of great importance on the vibration serviceability of footbridges. To account for the interaction effects between the human body and the footbridge, the former is often described by a mass-spring-damper (MSD) system. The parameters of this MSD system are in this contribution estimated by minimizing the discrepancy between the experimentally derived and the numerically simulated power spectral density of the structural response. The methodology assumes that the dynamic behavior of the empty structure, the average weight

Abstract:

The first bacterial and viral avirulence ( avr) genes were cloned in 1984. Although virus and bacterial avr genes were physically isolated in the same year, the questions associated with their characterization after discovery were very different, and these differences had a profound influence on the narrative of host-pathogen interactions for the past 30 years. Bacterial avr proteins were subsequently shown to suppress host defenses, leading to their reclassification as effectors, whereas research on viral avr proteins centered on their role in the viral infection cycle rather than their effec

Abstract:

Abstract Human-induced loads may produce resonance when the forcing frequency coincides with the natural frequency of the system. In this work, the dynamic assessment of a pedestrian cable-stayed bridge in Uppsala, Sweden is presented. The dynamic properties of the system have been identified and a loading scenario is evaluated. A comparison between the theoretical and measured acceleration of the bridge is made using a detailed finite element model. Different modelling aspects are considered and evaluated by studying their influence on the natural frequencies of the system such as the tie rod

Abstract:

This paper describes the first direct measurements of human-induced dynamic forces due to bouncing on a perceptibly moving force platform. A unique test rig, permitting a person to bounce physically on an idealized "single-degree-of-freedom system" with variable natural frequency and mass, is described and the test methodology explained. A set of representative results for different structure and bouncing frequencies is presented for one test subject. These results clearly demonstrate the effect that the flexibility of the structure has on the levels of force and dynamic response achieved. In
