coccolithophores are important primary producers in the modern world ocean and were almost certainly important in the mesozoic oceans, prior to the evolution and rise of diatoms in the phytoplankton. calcareous nannofossils are abundant, planktonic, rapidly evolving and largely cosmopolitan, so they are a good tool for biostratigraphy and paleoecology studies especially in the cretaceous system...

Wafer-to-wafer bonding processes for microstructure fabrication are categorized and described. These processes have an impact in packaging and structure design. Processes are categorized into direct bonds, anodic bonds, and bonds with intermediate layers. Representative devices using wafer-to-wafer bonding are presented. Processes and methods for characterization of a range of bonding methods a...

In the recent past, provenance – a research field that can be used to determine the origin and derivation history of data – has gained much attention [12]. Additionally, provenance is an important field for validating computation results. It covers coarse grained data as well as very fine grained information showing details of the implementation. Moreover, it is highly related to different topi...

this study aims at comparing the performance of logistic regression, maximum entropy, and multilayer perceptron techniques in preparing the predictive habitat distribution map of amygdalus scoparia in rangelands of qom province. for this purpose, vegetation sampling was done using random systematic methods after identifying pure habitats of this species. for soil sampling, eight profiles were e...

Shadow maps are a widely used means for the generation of shadows although they exhibit aliasing artifacts and problems of numerical precision. In this paper we extend the concept of a single shadow map by introducing dual shadow maps, which are based on the two depth layers that are closest to the light source. Our shadow algorithm takes into account these two depth values and computes an adap...

Ensuring product conformance according to 3GPP standards TS36.141 Base Station Conformance Test and TS36.521 UE Conformance Specification Radio Transmission and Reception is critical to any LTE device manufacturer. However, conducting common radio transmit characteristics, such as OFDM, MIMO, and Layers 1/2/3, based on these standards efficiently and accurately can be a challenge. Using designa...

Most of hybrid agent architectures are made by a hierarchical succession of a reactive (at a lower level) and a cognitive (at a higher level) layers. Each of these layers represents a behavior, a function, a decision, etc. Instead of using such functional layers, we propose in this paper a generic model of social hybrid agent, which is rather based on natural (animal/human) motivations of the a...
