The orientation of SFF-manufactured parts can have a signiicant eeect on the quality of the parts, in both surface eeects and strength. Currently, orientation is either ignored or set on the basis of experience. This paper takes some simple experiments and creates quantitative measures relating diierent aspects of part quality to orientation. This leads to several computational tools for optimi...

Recent efforts in reconstructing historical sea level change have led to a range of published estimates for the global mean sea level trend over the last century. Disagreement in these estimates can be attributed to two factors: (1) differences in analysis and/or reconstruction techniques and (2) differences in tide gauge selection and quality control of the data. Here the impact of tide gauge ...

The Wisconsin glaciation was started a approximately 125,000 years ago and reached its lowest extend between 20,000 to 21,000 years ago during which the sea level fell 120 to 130 meter. At the end of the ice age, about 18,000 years ago, the sea level increased and reached its present level about 5,000 years ago. The Persian Gulf was exposed in the last glacial moment (LGM). After this moment, t...

Low-latitude continental shelves, mixed siliciclastic–carbonate sedimentary systems, provide an understanding of sedimentary environments driven by paleoclimatological processes. The Bonaparte Gulf, northwestern Australian continental shelf, is among the widest in the world, ranging to 500 km, with shallow carbonate terraces and platforms that were exposed during periods of lower sea level. The...

in the past 25 years, rising of the caspian sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. the main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. the goal of this study is to introduce a proper setback line for th...
