Abstract:
A laminar flow micro fuel cell comprising of bridge-shaped microchannel is investigated to find out the effects of the cross-section shape of the microchannel on the performance. A parametric study is performed by varying the heights and widths of the channel and bridge shape. Nine different microchannel cross-section shapes are evaluated to find effective microchannel cross-sections by combining three bridge shapes with three channel shapes. A three-dimensional fully coupled numerical model is used to calculate the fuel cell’s performance. Navier-Stokes, convection and diffusion, and Butler-V

Circular tunnels are the most popular shapes used in urban underground transportation systems when mechanized tunneling is used for tunnel excavation. However, circular tunnels have a small space utilization ratio. With the material development, non - circular tunnels such as sub - rectangular, U - shaped lining, etc. are now common, and their cross - section helps to improve the underground space utilization. However, there have been not many studies on the structure and the calculation method of the metro tunnels with the above cross - sections. The paper uses the analytical synthesis method

Introduction. The current standards for the design of concrete and reinforced concrete structures provide no methods for calculating the strength of the oblique sections in bending elements of various cross-sectional shape under the action of transverse forces. This prompts the designers to use simplifications in calculation of such elements, which, in some cases, may lead to excessive consumption of transverse reinforcement or the strength underestimation.Aim.

Abstract An important issue in the design of the main visitable sewer collectors is the hydraulic calculation in permanent movement and non-permanent movement. Some main collectors that can be visited have non-standard flow sections, a situation that complicates the hydraulic calculation. Non-standard flow sections derive from standard sections (circular, ovoid, bell, rectangular and mixed) through natural and anthropogenic degradation processes. The initially designed section changes over time in terms of shape, dimensions and roughness, a situation in which determining the hydraulic paramete

An analytical method for studying flow in wavy channels is presented. The flow is considered laminar and steady, and the fluid viscoelastic. A shape factor is inserted in expressions for the stream function, thus allowing to model many different cross-section shapes that are the outcome of the chosen shape factor. This work aims at investigating kinematic aspects of the flow that may enhance heat transfer between the channel walls and the fluid.

Abstract:
In this investigation, a numerical procedure that can be used for the analysis of wheel/rail two-point contact geometries in turnout sections is developed. In turnout section, the tongue rail changes its shape along the track. Cross-sectional shapes of the tongue rail, therefore, need to be generated by interpolations along the rail and these profiles are used to determine the location of contact points for given location of wheelset along the track trajectory. Numerical examples of wheel/rail contact in point section are presented in order to demonstrate the use of the procedure developed in

Abstract:
Spiral mandrel dies are deeply integrated into the extrusion process and are the predominant die type for manufacturing products with a ring-shaped cross-section, e.g. blown film. The geometry of the axial spiral mandrel die is characterized by a spiral mandrel with one or more feed holes that merge into the spiral channels. The spiral channels themselves are embedded in the mandrel and have a characteristic u-shape in cross-section, which is dictated by the milling head used during manufacturing. In the past, numerous geometric parameters of the conventional axial spiral mandrel distributor h

Abstract:
This paper reviews developments in Europe from the eve of the introduction of the euro through the euro crisis. The paper begins with a discussion of the tax reform agenda. Although there are differences in the literature on specific taxes, and while European countries vary in their preferred levels of taxation, there is general consensus on the shape reforms should take. The paper then discusses the evolution of tax systems with the overall agenda in mind. It is found that overall revenue levels were broadly stable until just before the crisis, but marginal rates in corporate and top personal

Abstract:
In this study, we ask whether the U-shaped relationship between life satisfactionand age is flatter for individuals who are partnered. An analysis of cross-sectionalEU-SILC data indicates that the decline in life satisfaction from the teens to thefifties is almost four times larger for non-partnered than for partnered individuals,whose life satisfaction essentially follows a slight downward trajectory with age.However, the same analysis applied to three panel datasets (BHPS, SOEP andHILDA) reveals a U-shape for both groups, albeit somewhat flatter for the partneredthan for the non-partnered in

Abstract:
This paper documents disparities in cognitive development- as measured by a receptive vocabulary test-between children from households with high and low socioeconomic status (SES) in two different phases of childhood (before and after early school years) in four developing countries: Peru, Ethiopia, India, and Vietnam. Intercontinental evidence on the timing, shape, pattern, and persistence of these disparities is provided. The nonparametric analysis suggests that disparities found at age 5 persist into the early school years across all four countries, and the conditional analysis shows that S

Abstract:
Diversification of the economy, including exports, is a core goal of Saudi Vision 2030 (SV2030). The petrochemical sector can considerably contribute to the Kingdom’s diversification strategy, as it holds a substantial share in non-oil exports. First, this study econometrically estimated how exports of chemicals and rubber-plastics were shaped by theoretically articulated domestic and foreign factors over the 1993-2020 period. Then, the estimated export equations were integrated into a general equilibrium model, called the King Abdullah Petroleum Studies and Research Center (KAPSARC) Global En

Abstract:
Two basic factors shape private sector development in Belize. First, the population is small - only 322,000 as of mid-2008. This limits the size of the domestic market and potential economies of scale. The economy was only US$1.3 billion in 2009 and diversification is limited. The economy depends strongly on trade with the world economy, both as a market for domestic produce and as a source of the wide range of products that would be costly or impossible to produce domestically. Aside from Caribbean micro-states, Belize is the fourth most open economy in Latin America and the Caribbean (Figure

Abstract:
This paper presents advancements in a surrogate-based, rotor blade design optimization framework for improved helicopter performance. The framework builds on previous successes by allowing multiple airfoil sections to designed simultaneously to minimize required rotor power in multiple flight conditions. Rotor power in hover and forward flight, at advance ratio 𝜇 = 0.3, are used as objective functions in a multi-objective genetic algorithm. The framework is constructed using Galaxy Simulation Builder with optimization provided through integration with Dakota. Three independent airfoil sections

Abstract:
This Caribbean Region Quarterly Bulletin explores constraints to private sector development in the Caribbean. With economic growth weak and dependent on only a few sectors -either tourism or commodity exports- authorities in all countries aim at diversifying the economy and boosting private sector development. While the private sector in each country faces specific issues, most share challenges resulting from red tape, complicated and tedious processes and weak environments for doing business. As usual, the Quarterly Bulletin covers the economic developments in The Bahamas, Barbados, Guyana, J
