The aim of this paper is to provide a comprehensive review mode-division and spatial-division optical fiber sensors, mainly encompassing interferometers advanced gratings. Compared with their single-mode counterparts, which have very mature field many highly successful commercial applications, multimodal configurations developed more recently advances in device fabrication novel mode control de...

Studies on human activities and the natural water cycle as a coupled system are essential for effective resource management in river basins. However, existing calculation methods based solely do not meet accuracy requirements of society dualistic simulations. Therefore, it is necessary to establish more scientific reasonable unit division method confluence relationship determination method. Thi...

The purpose of this study is to provide a clearer idea for the optimization wetland functional areas and new method identification analysis under background latest Wetland Protection Law in China. This selected Pan’an Lake Wetland, first national park built coal mining subsidence land China, as research object. By constructing “Water-water-landscape-function” (WLF) model, combined with landscap...

We consider a size-structured model for cell division and address the question of determining the division (birth) rate from the measured stable size distribution of the population. We propose a new regularization technique based on a filtering approach. We prove convergence of the algorithm and validate the theoretical results by implementing numerical simulations, based on classical technique...

SRT division schemes are presented based on a redundant number operand format aiming high speed operation. The proposed SRT division method based on a redundant binary adder (RBA) and one based on a recoded binary signed digit adder (RBSDA) show a 33% and 50% speed improvement, respectively. The time complexity of the proposed division based on redundant number is O(n); importantly, the redunda...

The proposed divisive clustering method performs simultaneously a hierarchy of a set of objects and a monothetic characterization of each cluster of the hierarchy. A division is performed according to the within-cluster inertia criterion which is minimized among the bipartitions induced by a set of binary questions. In order to improve the clustering, the algorithm revises at each step the divi...
