Introduction: Several studies have contributed to our understanding of the record of alteration of CR chondrites [e.g., 1-5]. However, recent observations of CR2 GRA 06100 suggest that hydration of the CR parent body was a more diverse process than previously anticipated [6]. [6] observed that Fe,Ni metal in this meteorite was invariably and extensively altered to form complex assemblages conta...

Scalable and secure sharing of personal health record in cloud computing is an emerging trend in Health field for exchange and the use of personal Health information. This sensitive data is shared and stored by the third party reference in cloud computing. Therefore the need of encrypting data stored at this sites is highly essential to reduce the storage space and for the cost reduction. Since...

polymeric yarns for reinforcing cement composites have got great interest in all over the world. in this research the performance of bonding between nylon tire cord grad yarns, and one kind of cement composite called fine grained concrete was studied. two kinds of nylon cord yarns, nylon 6 and 66, with different finesse were selected. the durability of yarns with time in alkaline media was inve...

Automatically classifying plant leaves is a challenging fine-grained classification task because of the diversity in leaf morphology, including size, texture, shape, and venation. Although powerful deep learning-based methods have achieved great improvement classification, these still require large number well-labeled samples for supervised training, which difficult to get. In contrast, relying...

The latest effective defense against code reuse attacks is fine-grained, per-process memory randomization. However, such process randomization prevents code sharing since there is no longer any identical code to share between processes. Without shared libraries, however, tremendous memory savings are forfeit. This drawback may hinder the adoption of fine-grained memory randomization. We present...

With multi-core architectures now firmly entrenched in many application areas both computer architects and programmers now face new challenges. Computer architects must increase core count to increase explicit parallelism available to the programmer in order to provide better performance whilst leaving the programming model presented tractable. The programmer must find ways to exploit this expl...

Given two images, we want to predict which exhibits a particular visual attribute more than the other—even when the two images are quite similar. For example, given two beach scenes, which looks more calm? Given two high-heeled shoes, which is more ornate? Existing relative attribute methods rely on global ranking functions. However, rarely will the visual cues relevant to a comparison be const...

We performed experiments on two fine-grained classification tasks using a state-of-the-art pipeline (descriptor + dictionary + LLC encoding + max pooling + linear SVM). We found that this standard pipeline out-performed a dictionary-free classification technique (stacked evidence trees) that was specifically designed for fine-grained classification. The success of the method depends on two fact...
