Comparative Study on Time Averaged Wave Drifting Force
Frank Lin,Nigel White,Mohammad Hajiarab,Jun-Bum Park 대한조선학회 2011 대한조선학회 학술대회자료집 Vol.2011 No.11
With the evolution of technology, newly built ships become larger in size, and the second order hydrodynamics starts playing its role. The added wave resistance for a large vessel and longitudinal and horizontal drifting force on a FPSO are well known examples. In this paper a direct pressure integration method is presented and applied to a few comparative studies. First the results of longitudinal drifting force in short regular incident waves are compared with the experiments. Another case is for a FPSO in which the mean wave drifting forces for a number of wave conditions obtained from WAVELOAD are compared with the same AQWA model. Finally vertical and lateral wave drifting forces for a two-ship interaction model is analyzed and compared with the experimental data. The advantage and disadvantage of the direct pressure integration method is addressed and some key factors in computation of drifting force with the presented method are discussed.
Implications of Technology and Imports for Employment and Wages in Canada
( Frank C. Lee ) 세종대학교 경제통합연구소(구 세종대학교 국제경제연구소) 1999 Journal of Economic Integration Vol.14 No.2
This paper analyzes the net effects of technology and import competition on employment, wages and wage inequality in the Canadian manufacturing sector over the 1970-1990 period by estimating reduced form employment and wage equations. The analysis uses non-production and production workers to distinguish between two types of workers. For each group, person-hours worked, the level of employment and the hourly labor compensation by industry are examined. The major findings for the study are as follows: (1) the growth of employment and real hourly labor compensation in the Canadian manufacturing sector is positively related to technical progress and to the price of imports; (2) the relative employment of non-production to production workers is negatively related to technical progress, while the relative real hourly labor compensation of non-production to production workers is positively associated with technical progress; (3) the relative employment of non-production to production workers is negatively related to the price of imports, and the relative real hourly labor compensation is positively associated with the price of imports.
