Abstract: In order to improve the performance of helical springs, such as increasing the fatigue life and suppressing resonance, variable pitch angle and variable helix radius may be incorporated into ...

Abstract: This study is focused upon one example from a class of cam systems with a fluctuating rocker-arm ratio, known as “finger follower” cam systems. This class of cam systems is typically built ...

Abstract: The general dynamic equations of helical compression springs with circular wire cross section, variable pitch angle, and variable helix radius are derived. The equations are formulated by Hamilton’s ...

Abstract: Extremely hot and humid environments are common in numerous occupational settings. Construction work is tough and physically demanding, and the difficulty is exacerbated by the hot and humid weather of tropical and subtropical ...

Abstract: Over the past decade, corruption has elicited increasing attention in the construction industry, and several studies have been conducted and published on the topic of forms of corruption in the construction industry. ...

Abstract: This paper presents an evaluation model useful for assessing the suitability of public-private partnership (PPP) projects by studying their attractive and negative factors. A survey of industrial practitioners in Hong Kong ...

Abstract: A significant body of literature has been dedicated to research studies on construction labor productivity (CLP) and related issues, and many underlying theories and industrial practices on CLP application have been reported. ...

Abstract: Construction management (CM) as an applied academic discipline has a dual mission of creating scientific knowledge and solving practical problems. To do this, proper research approaches are required. Traditionally, CM ...
