public-private partnerships
No full textThesis(Master) -- KDI School: Master of Public Policy, 2022Despite the efforts being made globally to achieve sustainable development through public-private partnership projects, the number of canceled projects remains higher than concluded projects. Yet, we know very little about what determines the success of a PPP project. Review of the critical success factors (CSFs) that determine the success of PPP projects are outdated, and even when some information is available, it almost exclusively relies on qualitative case examinations. This paper attempts to fill this gap by first reviewing the existing literature to determine the list of CSFs. Then, via regression modeling, the paper attempts to determine a quantitative readiness index on the success of PPPs via four main groups: macroeconomic situation, favorable market conditions, governance & political climate, and regulatory & institutional environment. Based on the literature review, the study reveals the importance of nine CSFs: project type, project sector, contract period, private ownership, project financials, change in nations’ Gross Domestic Product (GDP), the consumer price index (CPI), income level target of the project, and the number of bids for a project. Using these factors as independent variables in a multivariate regression model, the paper finds that the factors identified explain over 71% of the variations in PPP success.INTRODUCTION

Numerical modeling of cone cracking in ceramics via indentation
No full textCeramic is a hard and brittle material with little ductility. It has wide applications in diverse industries viz. metallurgy, atomic energy, electronics, communication, space, military, insulation, biomechanical appliances etc. It is preferred material for armour protection due to its high strength-weight ratio. Its plastic deformation and failure behavior have, therefore, become a subject of extensive research in the recent past. Consequently, several material models were formulated in the second half of the nineteenth century by researchers such asJohnson- Holumquist, Rajendran-Grove, Deshpande-Evans etc. to study ceramic response under high-velocity impact. But these models are complex and require extensive calibration, while the Drucker-Prager (DP) Model is easy to implement. It was developed for study in soil and rock and is chosen to analyze ceramic quasi-plastic and tensile behaviour as part of research through the current thesis.Tensile ring and cone cracks, first observed by Hertz, are one of the modes of failure in brittle materials like ceramic. The prime objective of the thesis is the study of ceramic failure as well as cone crack initiation and its propagation through the ceramic body under the influence of varying material parameters such as cohesion, friction angle, dilatancy and softening of ceramics besides confinement by indentation. The Drucker Prager model is employed to studyindentation by simulation through numerical methods in JEM JIVE FEM library. Verification of the model was done through simulation of unit cubes subjected to unidirectional stresses at prescribed displacements. Suitable modification for pressure dependent softening behaviour of the ceramic is also made into the model and simulations undertaken in order to get insight into the nonlinear strength degradation of the ceramic post-elastic limit. Since the DP criteriontends to overestimate material strength, a suitable mechanism to limit the material strength is integrated with DP yield function and also to facilitate the comparison of results arrived through DP and modified yield functions. The results obtained by a simulated indentation in accordance with the DP formulation suggest that ceramic having high dilatancy, low friction angle and small softening modulus under confined conditions is more suited for use as armor protection. The pressure dependent softening behavior of ceramic is favorable for it being a good armor protection material. The DP Yield function modified to limit the material strength to a finite value, did not have any significant impact on crack initiation though the zone of compressive plastic strain grew in size during indentation. The DP based numerical model suffered from mesh sensitivity. The introduction of viscoplasticity to the numerical model was observed to have a positive influence in mitigating mesh sensitivity.Civil Engineering | Structural Engineerin
Challenges in conducting the undergraduate medical program in a medical school in Nepal: a personal selection
No full textContext: In Nepal, a developing country in South Asia, many medical schools have been opened in the private sector recently. KIST Medical College is a private medical school in Lalitpur district affiliated to Tribhuvan University. The college admitted the first batch of undergraduate medical (MBBS) students in 2008 and has recently admitted its fourth batch of students. Justification: Nepal, a country in transition had suffered from a decade long violent conflict. The country is in the process of writing a new constitution and suffers from political instability which may have a contributory role to many of the challenges which I will be enlisting in the article like frequent general shutdowns, load shedding, reduced number of patients in the teaching hospital and problems in conducting the academic calendar on schedule. Method: The challenges mentioned have been listed on the basis of the personal experience of the author and following discussion with colleagues in the institution and in other medical schools. Statement of the problem: Among the major ones are shortage of electricity and blackouts in winter, voltage fluctuations, frequent bands or general shutdowns, reduced number of inpatients in the teaching hospital during certain seasons and problems with internet connectivity. Possible solutions: The solution of many of these problems may be linked to political stability. Load shedding can be reduced by greater investment in production capacity and using other energy sources and reducing dependence on hydroelectricity. Creating a conducive climate for investment and industrial growth is necessary. Conclusion: The challenges can be overcome by various actors (political and non-political) working together in cooperation and creating a peaceful and stable political climate
The Art of Living. Un mouvement indien au-delà des clivages religieux ?
No full textInternational audienceThe Art of Living (TAOL) is a new religious movement whose popularity has not ceased to grow in the whole Indian sub-continent, and beyond. Founded and carried out by Sri Sri Ravi Shankar, the movement promotes a spirituality accessible to all, based on simplified yogic practices and a philosophical teaching of neo-vedantic inspiration. Thus, the guru intends to join together a transnational community around a universal spirituality, transcending individual religious backgrounds. In order to understand the motivating forces behind the international success encountered by TAOL, the author goes back over the genesis of the movement and focuses on the various strategies which govern its community development, be it in its Indian context of birth, or on a world-wide scale.The Art of Living (TAOL) est un nouveau mouvement religieux dont la popularité ne cesse de croître dans l'ensemble du sous-continent indien et au-delà. Fondé et mené par Sri Sri Ravi Shankar, le mouvement promeut une spiritualité accessible à tous, basée sur des pratiques yogiques simplifiées et un enseignement philosophique d'inspiration néo-védântique. Le guru entend ainsi réunir une communauté transnationale autour d'une spiritualité à vocation universelle, transcendant les appartenances culturelles et religieuses individuelles. Afin de comprendre les ressorts du succès international que rencontre actuellement TAOL, l'auteur revient sur la genèse du mouvement et s'intéresse aux stratégies de diffusion qui président à son développement communautaire tant dans son contexte de naissance indien qu'à l'échelle planétaire
Prediction of Fatigue Crack Propagation in Orthotropic Steel Decks using XFEM based on LEFM and VCCT
No full textOrthotropic Steel Decks (OSDs) are widely used in various types of steel bridges due to their benefits of light weight, high load bearing capacity and speedy construction. Although many improvements in aspects of design, fabrication, inspection, and maintenance have been achieved over the years for such bridge decks, fatigue remains a predominant problem, mostly because of the complexity of prediction methods. Many researchers have tried to investigate this component through experiments. However, performing only experiments may not lead to a cost-effective solution. Therefore, it is necessary to combine the experimental data with the numerical approaches. Particularly Linear Elastic Fracture Mechanics (LEFM) allows to model and analyse the crack propagation until subsequent failure, and significantly reduces the requirement of experiment. ABAQUS® provides an enriched feature, commonly referred to as the Extended Finite Element Method (XFEM) which incorporates two enrichment function namely the discontinuity function which represents the gap between the crack surface and asymptotic function which captures the singularity and thus can be used to model discontinuity independent to the finite element mesh. To evaluate the modelling efficiency and validate the simulation methodology, two XFEM-model based on LEFM and Virtual Crack Closure Technique (VCCT) are developed and the simulated results are compared with the experimental data. The first phase of the thesis deals with the numerical simulation to investigate the crack propagation rate in Compact-Tension (CT) specimen for different stress ratios. The results of two-dimensional (2D) model are found to be in good agreement (within 1.48%) with the fatigue coupon test results. As most of the work concentrates on 2D shell model, the extension to three-dimensional (3D) solid requires the investigation of related parameters to consider through-thickness effects. Nevertheless, the mechanism of 3D model is studied, and the simulated results match with the 2D results for fatigue crack growth (a, N). Moreover, a reliable technique of computing Stress Intensity Factor (SIF) is obtained by comparing with the ISO 12108 standard formulation. However, when the SIF and fatigue crack growth are combined, the crack propagation rate in 3D is overestimated (about 26%) when compared to the experimental data possibly because of the imperfection in the application of boundary conditions. The second phase deals with the numerical simulation in welded connection of OSD to determine the Paris law constants (C, m) by correlating the numerical result of fatigue crack growth with the beach mark measurements obtained in the fatigue experiments. Prior to automated XFEM simulation, a set of finite element analyses are performed to determine the vertical deformation, longitudinal stain distribution and hotspot stresses to validate the numerical model as per the test setup. The results of numerical analyses showed a good correlation (within 18%) with test data and Paris law constant C is predicted to be lower than the recommended value by IIW standard. The validated methodology is then applied on large scale to an existing bridge (Suurhoff bridge) structure which was built in 1971. In this case study, a crack length of 230 mm was detected in the deck plate originating from the root of the stiffener-to-deck plate welded connection between the cross-beams using TOFD measurements. To verify the problem, a numerical model is developed based on the dimension of the bridge to evaluate the crack initiation period and the crack propagation period. The crack initiation period is predicted using hotspot stress method and the crack propagation period is evaluated using automated XFEM simulation. Overall, the total fatigue load cycles are predicted to be 7.86 million which is equivalent to 48 years. A similar crack length was however detected after a service life of 44 years. This overestimation can be possibly explained as the model did not take residual stresses and other welding defects into account. The numerical model showed a good correlation with the real scenario and is therefore used to predict the permissible limit of deck plate crack length of 500 mm. The model predicted 8.02 million load cycles for a crack length of 500mm, which is equivalent to 34 years after the crack initiation period. Nevertheless, the fracture mechanics approach showed improvements in the assessment of fatigue life.Civil Engineerin
