The time delay is a key parameter for modeling fluidelastic instability, especially the damping controlled mechanism. It can be determined experimentally by measuring directly the time lag between the tube motion and the induced fluid forces. The fluid forces may be obtained by integrating the pressure field around the moving tube. However, this method faces certain difficulties in two-phase flow since the high turbulence and the non-uniformity of the flow may increase the randomness of the measured force.

Abstract:
Novel computational and small-scale experimental investigations were performed in order to better understand the high velocity flow behavior of gas-particle mixtures. The motion of solid objects impacted by the flow of the mixtures was measured by use of high-speed digital video photography. Computations were performed by use of an arbitrary Lagrangian Eulerian (ALE) treatment in a nonlinear finite element code. Constitutive models for description of the solid component of the gas-particle blend were developed based on quasi-statically determined test results. It was observed that there was ve

Abstract:
Honeycomb cellular structures, due to their light weight and high energy absorbing, have been used extensively as energy absorbers or cushions to resist external loads. In this paper, the mean crushing stress and the wavelength of the folding mode, as two important parameters in the study of metal square honeycomb crushing under quasi-static loading have been investigated theoretically and experimentally. Firstly, by considering the true cylindrical curvature effects and the flow stress in the folding mode of the honeycomb material, the Wierzbicki’s model in the study of metal hexagonal honeyc

Abstract In this paper, pipe elbow under cyclic in-plane bending loads was evaluated using strain-based evaluation methods. For strain-based evaluation methods, acceptance criteria for local failure presented in ASME BPVC Sec. VIII and the void growth/shrinkage model were considered. The void growth/shrinkage model is evaluation model that incorporates the void growth effect to the acceptance criteria presented in ASME BPVC Sec. VIII. For the validation of evaluation models, predicted failure cycle of pipe elbow was compared with experimental results. The ASME BPVC Sec. VIII method gives very

Abstract:
The purpose of this guideline is to provide ideas and technical advice on how to measure the effectiveness of Science, Technology and Innovation Programs (STIP). The paper addresses the specific challenges of evaluating STIP, from the assessment of the intervention logic to the choice of the most appropriate method to solve the attribution problem. Much attention is devoted to the topic of data, discussing pros and cons of different data sources, data quality issues, and strategies for data collection.

Abstract:
Although the nonhormonal copper intra-uterine device (IUD) is the safest and cheapest long-acting contraceptive method, its use has been declining day-by-day in Bangladesh. Less than 1% of married women 15-49 years of age who currently use a contraceptive method use an IUD. Researchers conducted a quasi-experimental pre-post-test non-equivalent control group designed study to test a simple intervention intended to increase acceptance, use, and continuation of the IUD among married women of reproductive age (18 to 45 years) in Keraniganj, Savar, and Nawabganj Upazilas (sub-districts) in Banglad

This pilot quasi-experimental project examines the effectiveness of an adapted flipped classroom approach for the teaching of 2 teacher education courses over a semester of 13 weeks. Both the experimental and control groups would be matched at programme level. The control group would be two comparable classes not using the flipped classroom approach but using the didactic or traditional approach of teaching. The flipped classroom approach is also known as the Thayer Method or the inverted classroom or reverse teaching. It involves interactive student-centred engagement pedagogy with individual

Abstract:
Do U.S. households with battery electric vehicles (BEVs) drive less or more than U.S. households with internal combustion engine vehicles (ICEVs)? Answering this question is important to policymakers and transportation planners concerned with reducing vehicle miles traveled and the emissions of greenhouse gases from transportation. So far, this question has not been answered satisfactorily, possibly because of the relatively low number of EVs in the U.S. until recently, but also because of methodological issues. In this paper, we aim to fill this gap by analyzing data from the 2017 National Ho
