For original submission and image(s), see ARM Research Highlights http://www.arm.gov/science/highlights/ Research Highlight Subgrid-scale variability is one of the main reasons why parameterizations are needed in large-scale models. Similarly, subpixel-scale cloud heterogeneity also plagues satellite retrievals of cloud and aerosol properties. Cloud heterogeneity, to some extent, can be represe...

The solar radiation is the origin of energy for the photosynthesis and forest productivities. On the other hand, clouds constantly appear, move and disappear all the time and influence atmospheric and radiation conditions at the same time. Therefore, to understand cloud parameters which consist of cloud covers, its distributions and types etc. for a short time interval can help us to estimate s...

Security concerns are a substantial impediment to the wider deployment of cloud storage. There are two main concerns on the confidentiality of outsourced data: i) protecting the data, and ii) protecting the access pattern (i.e., which data is being accessed). To mitigate these concerns, schemes for Oblivious Storage (OS) have been proposed. In OS, the data owner outsources a key-value store to ...

A temporal subtraction image, which is obtained by subtraction of a previous image from a current one, can enhance interval changes on a chest radiograph by removal of most normal structures. However, subtraction artifacts, which tend to reduce its effectiveness in the detection of interval changes, were still included in the conventional method. In this study, we have developed a pixel matchin...

abstract background: clinical risk index of babies (crib), score for neonatal acute physiology (snap), an update of the clinical risk index for babies score (crib ii) and score for neonatal acute physiology - perinatal extension (snap-pe) are scoring devices developed in neonatal intensive care units. this study reviewed these scoring systems in critically ill neonates to determine how well the...

The authors propose a new method for the assignment of rainfall confidences on a pixel basis using cloud properties derived from optical satellite data during daytime. This approach is based on the concept model that the probability for precipitation is a function of the liquid water path, which in turn can be computed using the satellite-retrieved cloud optical thickness and the cloud effectiv...

The contrast of an image is a feature which determines how image looks better visually. In this paper, we are analysing the capability of activation functions for contrast enhancement. Activation functions are classically used in neural network. In this paper, Activation function creates a mask which is operated on the image on pixel by pixel basis. On the basis of activation function the pixel...

Pixel value access control (PVAC) was introduced to deliver a secure and simple graphical password method where it requires users load their image as password. PVAC extracts the obtain three-octet 8-bits Red-Green-Blue (RGB) its authenticate user. The pixel must be matched with record stored in database or otherwise, user is failed authenticate. However, which prefer store images on cloud stora...

aerosol formation due to ions in the atmosphere is not well understood, although it seems to play an important role in cloud formation. the ions in the atmosphere can enhance cloud formation and can increase nucleation as well as impeding the evaporation from the surfaces of the droplets. recently there has been some experimental work to find the relation between ions concentrations and cloud i...
