This paper investigates natural convection heat transfer of generalized Oldroyd-B fluid in a porous medium with modified fractional Darcy's law. Nonlinear coupled boundary layer governing equations are formulated with time–space fractional derivatives in the momentum equation. Numerical solutions are obtained by the newly developed finite difference method combined with L1-algorithm. The effects of involved parameters on velocity and temperature fields are presented graphically and analyzed in detail. Results indicate that, different from the classical result that Prandtl number only affects the heat transfer, it has remarkable influence on both the velocity and temperature boundary layers, the average Nusselt number rises dramatically in low Prandtl number, but increases slowly with the augment of Prandtl number. The maximum value of velocity profile and the thickness of momentum boundary layer increases with the augment of porosity and Darcy number. Moreover, the relaxation fractional derivative parameter accelerates the convection flow and weakens the elastic effect significantly, while the retardation fractional derivative parameter slows down the motion and strengthens the elastic effect.

Toole, Hallowell and Chinowsky (2013) define innovation as, “the act of introducing a significant improvement in a process, product, or system that is novel to the organization, may cause individuals to view things differently, and results in competitive advantage, increased value for the client or benefit to stockholders”. The road construction industry needs new applications from the view point of innovation and technology (Caerteling et al., 2009). Focus needs to be on enhancing road industry performance considering that road infrastructure is a substantial contributor to employment and gross domestic product (Caerteling et al., 2011). Based on limited literature available on application of innovative technologies in the road sector, typical examples reported are: solar roads, Smart highways in the Netherlands that glow in the dark, new road surface material, CFA (Continuous Flight Augur) piling, Moveable barrier system, use of recycled material and others. This paper presents an overview of innovation in the road construction sector, the driving factors behind adopting new techniques and materials; and the barriers it faces in their application.
Toole, Hallowell和Chinowsky(2013)将创新定义为“对组织来说是新颖的过程,产品或系统进行重大改进的行为,可能会导致个人以不同的方式看待事物,并导致竞争优势,为客户增加价值或为股东带来利益”。从创新和技术的角度来看,道路建设行业需要新的应用(Caerteling et al., 2009)。考虑到道路基础设施是就业和国内生产总值的重要贡献者,重点需要放在提高道路行业绩效上(Caerteling et al., 2011)。基于有限的关于创新技术在道路领域应用的文献,报道的典型例子有:太阳能道路、荷兰在黑暗中发光的智能公路、新型路面材料、CFA(连续飞行预测)打桩、可移动屏障系统、回收材料的使用等。本文概述了道路建设领域的创新,采用新技术和新材料背后的驱动因素;以及它在应用中面临的障碍。

Construction professional service (CPS) in the international arena has been very competitive despite that the industry is proliferating at a high rate. To excel in international business, CPS firms have the importance of building overseas competition strategies on a proper understanding of the international CPS (I-CPS) market. However, subject to borderless trade, information technology–based networking, global outsourcing, and changing forms of procurement, the I-CPS market structure has become more covert, intricate, and unstraightforward than before. Through examining business competition among top international design firms, this study aims to identify the attributes of the I-CPS market structure from two perspectives—concentration and turnover. Data from Engineering News-Record over the period 2001–2011 were collected to calculate market concentration ratios and turnover indices. The results show that I-CPS competition is characterized by atomism, much turbulence with a steady increase in competition intensity, and the predominant role of new entrants and exiting firms in market turnovers. The combination of concentration and turnover is found useful to address the attributes of the I-CPS market structure, which favors I-CPS firms to formulate international competition strategies in due ways.
