基于CT技术沥青混合料集料的识别与分离

为了研究沥青混合料内部集料结构,利用CT断层扫描技术对沥青混合料内部集料进行三维重构,基于Matlab自行编制程序对集料进行识别与分离.很多情况下集料是互相接触的,这些相互接触的集料容易被程序错误地识别成是一个集料.为此首先用Gaussian过滤器使集料变得更光滑,再利用Hmax过滤器使集料变得更平滑,最后进行Wat...     

Integrated Coastal Zone Management Law in the European Union

The achievement of integrated coastal zone management (ICZM) in the European Union inevitably raises questions of law. Law has the potential to assist ICZM, but it also has the capacity to impede it. The European Demonstration Programme on ICZM has revealed considerable diversity within the 13 national legal systems governing the European Union (EU) coastal zone, but it has also shown a similarity of legal problems and has identified some examples of good practice. There are already provisions of European Community (EC) and international law that exert a unifying influence on aspects of coastal management in Europe. However the constitutional powers of the EU are limited by the legal principles of subsidiarity and proportionality, and any ICZM initiative must be consistent with these. The potential mechanisms available include a legally binding EC directive, but the European Com mission has instead preferred a nonbinding recommendation and strategic guidance. Each approach offers some practical advantages and disadvantages, but the success of any method will ultimately depend upon political will.
