Due to resource restricted sensor nodes, it is important to minimize the amount of data transmission among sensor networks so that the average network lifetime and the overall bandwidth utilization are improved. To reduce the amount of sending data, an aggregation approach can be applied along the path from sensors to the sink. It means computing and transmitting partially aggregated data to th...

Information extraction or knowledge discovery from large data sets should be linked to data aggregation process. Data aggregation process can result in a new data representation with decreased number of objects of a given set. A deterministic approach to separable data aggregation means a lesser number of objects without mixing of objects from different categories. A statistical approach is les...

Parallel Wireless Communications area of research that enables mobile clients to multiple wireless networks concurrently. This concurrent bandwidth aggregation techniques t wireless communications on mobile devic aggregation can be performed using wireless device or cooperatively across devices within w of each other.. The aggregation can be a application-layer, transport layer like Multi layer...

The separation of cells or particles from solution has traditionally been accomplished with centrifuges or by sedimentation; however, many particles have specific densities close to unity, making buoyancy-driven motion slow or negligible, but most cells and particles carry surface charges, making them ideal for electrophoretic separation. Both buoyancy-driven and electrophoretic separation may ...

A global sensitivity analysis was conducted on the algorithm implemented in the Echoview w software to detect and describe aggregations in acoustic backscatter. Multiple aggregation detections were performed using walleye pollock (Theragra chalcogramma) data from the eastern Bering Sea. Walleye pollock form distinct aggregations and dense and diffuse layers. In each aggregation detection, input...

Applied network science often involves preprocessing network data before applying a network-analysis method, and there is typically a theoretical disconnect between these steps. For example, it is common to aggregate time-varying network data into windows prior to analysis, and the trade-offs of this preprocessing are not well understood. Focusing on the problem of detecting small communities i...

The process of colloidal drying gives way to particle self-assembly in numerous fields including photonics or biotechnology.

Via electroless metal deposition, well-defined silver dendrites and thin porous silicon (por-Si) layers are simultaneously prepared in ammonia fluoride solution containing AgNO3 at 50 C. A self-assembled localized microscopic electrochemical cell model and a diffusion-limited aggregation mode are used to explain the growth of silver dendrites. The formation of silver dendritic nanostructures de...

Characterizing in situ water turbidity is critical to numerous naval operations. In particular, water column turbidity impacts the efficacy of sensors that use optical measurements for a variety of purposes including laser detection of mines and prediction of the operational detection horizon for bioluminescence and diver visibility algorithms. Nepheloid layers, are optically significant and re...
