Piles installed in row(s) are used as an effective technique to improve the stability of soil slopes. The analysis of pile-stabilized slopes require a reliable prediction of lateral resistance offered by the piles. In this work, an analytical solution is developed to estimate the lateral resistance offered by the stabilizing piles in sand and c − ϕ soil slopes considering soil arching phenomenon. The soil arching in both horizontal direction (between the neighboring piles) and vertical direction (in the active wedge in front of the pile row) are studied and their effects are incorporated in the proposed model. The shape of soil arch is assumed to be circular and principal stress trajectories are defined separately for both modes of arching. Experimental and numerical studies found in literature were used to validate the proposed method. A detailed parametric analysis was performed to study the influence of pile diameter, center-to-center spacing, slope angle and angle of internal friction on the lateral pile resistance. © 2020 Techno-Press, Ltd.

The current paper presents a meshless formulation for the analysis of geometrically nonlinear one-dimensional Euler-Bernoulli beams. Element-free Galerkin method (EFGM) is used as the meshless numerical tool and Newton-Raphson method as the iterative scheme. Numerical examples of beams with four different boundary conditions are solved, and the results are compared with that of the finite element method (FEM). EFGM results are found in good agreement with that of FEM. Also, it is found that EFGM eliminates the effect of membrane locking in thin beams. © Published under licence by IOP Publishing Ltd.

This work aims to economically evaluate centralized and decentralized Sewage Treatment Plants (STPs) for a metropolitan city. For the same, centralized and decentralized wastewater treatments for a catchment area in Sharjah city (United Arab Emirates) were evaluated by Net Present Value (NPV) method. Three options meeting local government regulations were considered for the catchment. Options 1 and 2 were centralized, and Option 3 was decentralized. Option 1 was about connecting the catchment to the existing centralized STP location, Option 2 to connect the catchment to the new proposed location which may be situated at the lowest point around the catchment area, and Option 3 involved constructing three decentralized STPs. The results showed that Option 3 had the lowest NPV of costs including CAPEX and OPEX for 25 years. There was a saving in Option 3 of around 44% compared to Option 1, and 23% compared to Option 2. This finding is useful for engineering managers for infrastructure planning for a metropolitan city like Sharjah city. © IEOM Society International.

The concept of Public Private Partnerships (PPP) Projects is a widely used method of executing infrastructure projects around the world, where it utilizes the private sector's contribution to benefit both the public agency as well as the private sector implementing the project. The PPP project delivery methods are relatively new to the developing middle-eastern region generally, and to the UAE specifically and there has been very few completed PPP Projects. This paper aims towards investigating risks related to the PPP Projects by ranking such risks in order of importance and rate of occurrence. To achieve this task, relevant data that would contribute to the analysis of the risks are collected. The method of data collection for this paper was a series of surveys and semi-structured interviews directed towards informed targets representing the different stakeholders of PPP projects such as Private Proponent Managers, Federal Government Officers, Engineering Practitioners etc. The analysis of the survey results showed that the risks concerned with the private sector were significantly different than those concerned with the public sector. The research also concludes that proper risk mitigation measures must be implemented in order to optimize the process of utilizing the concept of PPPs in the UAE. © 2020 IEEE.

Investigation of Project Delivery Risks in Public-Private-Partnership (PPP) Infrastructure Projects in UAE - A Stakeholder's Perspective

Road networks are susceptible to disruptions. Since disruptions on certain roads have graver impacts, critical link identification is vital in disruption preparedness. To identify critical links, most approaches systematically inject disruptions and evaluate the ensuing after-effects. Since degradation patterns are uncertain, such iterative approaches either presume knowledge of disruption patterns or try numerous patterns but soon escalate to computational impracticality on real-life road networks. This study obviates both, using a novel approach which measures the contribution of each link to a predefined operational limit on the network. It generates a criticality hierarchy on real-life networks, while on hypothetical symmetric networks it rightly identifies all links as critical. © Indian Academy of Sciences.

Freight forecasting models have been significantly improved in recent years, especially in the field of goods vehicle behavior modeling. On the other hand, the improvements to commodity flow modeling, which provide inputs for goods vehicle simulations, were limited. Contributing to this component in urban freight modeling systems, we propose an error component logit mixture model for matching a receiver to a supplier that considers two-layers in supplier selection: distribution channels and specific suppliers. The distribution channel is an important element in freight modeling, as the type of distribution channel is relevant to various aspects of shipments and vehicle trips. The model is estimated using the data from the Tokyo Metropolitan Freight Survey. We demonstrate how typical establishment survey data (i.e. establishment and outbound shipment records) can be used to develop the model. The model captures the correlation structure of potential suppliers defined by business function and provides insights on the differences in the supplier choice by distribution channel. The reproducibility tests confirm the validity of the proposed approach, which is currently integrated into a metropolitan-scale agent-based freight modeling system, for practical use. © 2018, The Author(s).

Commodity flow estimation for a metropolitan scale freight modeling system: supplier selection considering distribution channel using an error component logit mixture model

Despite significant advances in freight transport modeling in recent years, there is still lack of available tools for evaluating novel logistics solutions. We introduce the framework of SimMobility Freight, which is part of SimMobility, a multi-scale agent-based urban transportation simulation platform. SimMobility Freight is capable of simulating commodity contracts, logistics and vehicle operation planning and parking decisions in a fully-disaggregate manner. This allows us to evaluate alternative logistics solutions and measure their impacts. To illustrate its capability, we conduct an analysis of delivery time window regulations, assessing the policy impacts. © 2020 Elsevier Ltd
