This paper presents a new ILP processor architecture calledCompressed VLIW (CVLIW). The CVLIW processor constructs a sequence of long instructions by removing nearly all NOPs (No OPerations) and LNOPs (Long NOPs) from VLIW code. The CVLIW processor individually schedules each instruction within long inamctions using fonctional unit and dynamic scheduler palm Every dynamic scheduler in the CVLIW processor individually checks for data dependencies and resource collisions while scheduling each insu'uction. In this paper, we simulate the architecture and show that the CVLIW processor performs better than the VLIW prueesser for a wide range of cache sizes and re:ross various numerical benchmark applications. These performance gains of the CVLIW processor n~,dt from individual inslruction scheduling and size reduction of object code. Even though we assume a cache with a zero miss rate, the CVLIW's performance is still 9%--15% higher than that of the VLIW processor regardless of benchmark applications.

Numerical analyses were performed to study the cluster suction bucket foundation performance in comparison with the monopod suction bucket foundation. The possibility of improving the resistance performance of suction bucket foundations by using cluster configuration was studied. Clustered foundations are formed by arranging multiple bucket foundations in relatively short distances among them. A model cluster foundation composed of three individual buckets was configured such that it has the same cross sectional area, length and total bucket weight to a monopod foundation. Results of numerical modeling are presented in the form of load-displacement curves. Vertical, horizontal and horizontal combined with moment load conditions were considered. The results show that the cluster type configuration improved the resistance performance of the foundations under typical loading conditions.

For circular rigid footings with a rough base on sand, combined vertical -moment loading capacity was studied by three-dimensional numerical modelling. Mohr-Coulomb plasticity model with the associated flow-rule was used for the soil. After comparing the results of the swipe loading method, which can construct the interaction diagram with smaller number of analyses, and those of the probe loading method, which can simulate the load-paths in the conventional load tests, it was found that both loading methods give similar results. Conventional methods based on the effective width or area concept and the results by eccentricity factor (  ) were reviewed. The results by numerical modelling of this study were compared with those of previous studies. The combined loading capacity for vertical (V) -moment (M) loading was barely affected by the internal friction angle. It was found that the effective width concept expressed in the form of eccentricity factor can be applied to circular footings. The numerical results of this study were smaller than the previous experimental results and the differences between them increased with the eccentricity and moment load. Discussions are made on the reason of the disparities between the numerical and experimental results, and the areas for further researches are mentioned.요 지

Penetration resistance of bucket foundations with skirt wall in the silty sand of the western coast of Korea was analyzed by centrifuge modelling. The penetration resistance is induced when the bucket foundations are jacked into the soil without suction, and is directly related to the self-weight penetration depth. The procedure by Houlsby and Byrne (2005), which takes into account the effect of stress increase by frictional resistance of skirt wall, was utilized to generate the penetration resistance similar to the experimental results. This paper describes the methods by which major parameters such as lateral earth pressure coefficient and friction angle between the skirt wall and the soil are evaluated. The effect of changes in these parameters on the predictions is analyzed. Also, observed soil behaviour during jacking penetration is investigated.
