Abstract:
Behaviour under torsion is an important performance-related property of automotive box sections. A previous experimental study has identified joining technique, section thickness and section area as the major influencing factors on the torsional behaviour of box hat sections. Using these test results as the basis, a finite element modelling strategy that can simulate the behaviour of adhesively bonded and spot-welded automotive box sections subjected to torsion is presented. The numerical study investigated the effects of material representation, mesh density and layout, and joining technique

The cross section of Hybrid Double-I-Box Beam section is distinctive, which has advantages of both an ‘I’ section and a closed-box section. A total of 24 sections in three series that includes 8 homogeneous sections and 16 hybrid sections were tested under four-point bending.

Abstract:
This study compares plastic deformation behavior in box girder bridges with multiple boxes and cellular box cross-sections. The cross-section's shape significantly influences the girder's post-yield behavior despite being designed to have the exact yield moment. Steel's stress-strain relationship undergoes linear behavior until the yield stress is reached, followed by strain hardening. This study aims to assess the impact of strain hardening on the plastic behavior of girder box bridges.Two types of box girder sections, multiple box and cellular box, are designed with equivalent yield moments.

Damage identification is an important topic in structural assessment and structural health monitoring (SHM). Vibration-based identification techniques use modal data to identify the existence, location and severity of possible damages in structures, often via a numerical model updating procedure. Among other factors influencing the practicality and reliability of a damage identification approach, two are of primary interest to this study. The first one concerns the amount and quality of modal data that can be used as ‘response’ data for the model updating. It is generally recognised that natur

Abstract:
&lt;p&gt;The Box section has complicated mechanical behavior under loads, including in-plane and out-of-plane stresses in each slab of box components. Traditional checking stresses originated from simple open sections, such as rectangular, T and I sections, featured by normal stresses at extreme fibers and shear stress in the web. For statically indeterminate box sections, cracks found in the outside surface of the web were much different from those found inside the web. This means that the stress indicator for the outside surface of the web should be different from the stress indicator for th

Abstract:
In this paper we study neural networks and their approximating power in panel data models. We provide asymptotic guarantees on deep feed-forward neural network estimation of the conditional mean, building on the work of Farrell et al. (2021), and explore latent patterns in the cross-section. We use the proposed estimators to forecast the progression of new COVID-19 cases across the G7 countries during the pandemic. We find significant forecasting gains over both linear panel and nonlinear time-series models. Containment or lockdown policies, as instigated at the national level by governments,

Abstract:
Broadband has a potential impact on the base of the pyramid (BOP), a segment of the population previously excluded from markets, and which lacks access to quality goods and services. Broadband facilitates the development of new business models that are more effective and efficient in terms of accessing, creating, and distributing goods and services to the BOP. A variety of private-sector-led broadband initiatives involving the BOP around the world have demonstrated profitability, while also providing social and economic returns along the value chain.

Abstract:
This paper discusses the radical change of the role of the public sector in the financing of infrastructure projects during the nineties. The generalized response to the new environment has taken the form of arrangements in which private initiative is empowered to construct and finance the projects, retaining their ownership temporarily. These arrangements, which are referred to as Build-Lease-Transfer (BLT) and Build-Operate-Transfer (BOT), respectively, have proved to be an efficient approach to develop infrastructure that the public sector by itself could not undertake.

How, for whom, and under what conditions does Participatory Action Research (PAR) generate innovation to tackle the drivers of the worst forms of child labour (WFCL)? This paper presents the findings of a realist evaluation that investigated how PAR groups facilitated children who work in exploitative and harmful labour and business owners in the leather industry in Bangladesh and the adult entertainment sector in Nepal to generate innovative actions. These PAR groups were facilitated over a period of 18 months to two years by non-governmental organisation professionals trained in PAR approach
