Plant identification and classification are critical to understand, protect, conserve biodiversity. Traditional plant requires years of intensive training experience, making it difficult for others classify plants. leaf is a challenging issue as similar features appears in different species plant. With the development automated image-based classification, machine learning (ML) becoming very pop...

Die-stacked DRAM has been proposed for use as a large, high-bandwidth, last-level cache with hundreds or thousands of megabytes of capacity. Not all workloads (or phases) can productively utilize this much cache space, however. Unfortunately, the unused (or under-used) cache continues to consume power due to leakage in the peripheral circuitry and periodic DRAM refresh. Dynamically adjusting th...

We have studied a superbounce scenario in set up of Brans-Dicke (BD) theory. The BD parameter is considered to be time dependent and assumed evolve with the scalar field. In scenario, model bounces at an epoch corresponding Big Crunch provided ekpyrotic phase continues until that time. Within given we investigate evolution for different equations state. chose axially symmetric metric has axial ...

The current cosmic acceleration does not imply that our Universe is basically de Sitterlike: in the first part of this work we argue that, by introducing matter into anti-de Sitter spacetime in a natural way, one may be able to account for the acceleration just as well. However, this leads to a Big Crunch, and the Euclidean versions of Bang/Crunch cosmologies have [apparently] disconnected conf...

The present work investigates some exact solutions of the gravitational wave equation in widely used cosmological spacetimes. examples are taken from spatially flat and closed isotropic models as well Kasner metric which is anisotropic. Various matter distributions considered, standard dust or radiation distribution to exotic matters like that with an state $$P = - \frac{1}{3} \rho $$ . In almo...
