In-network data aggregation is widely recognized as an acceptable means to reduce the amount of transmitted data without adversely affecting the quality of the results. To date, most aggregation protocols assume that data from localized regions is correlated, thus they tend to identify aggregation points within these regions. Our work, instead, targets systems where the data sources are largely...

Travel time and speed estimation are part of many intelligent transportation applications. Existing approaches rely on either function fitting or data aggregation represent different tradeoffs between generalizability accuracy. Function-fitting learn functions that map feature vectors of, e.g., routes to travel estimates, which enables generalization unseen routes. However, mapping imperfect of...

In our contribution we discuss the power stability of 1-Lipschitz binary aggregation functions. The main result is the characterization of power stable quasi-copulas by means of their dependence functions. The notions are illustrated by examples.

Wireless Sensor Networks consist of multiple energy-constrained sensing devices called sensor nodes. Typically, the sensor nodes generate data that must reach a single data sink across multiple hops. The data from neighboring nodes are usually correlated and can be aggregated and compressed inside of the network. This process is referred to as data aggregation and requires the development of da...

Abstract Introduction Platelet aggregation plays a significant role in the etiology of cardiovascular diseases. Therefore, treatments to inhibit platelet aggregation can reduce the risk of coronary thrombosis. Several studies indicated that garlic can inhibit platelet aggregation. This study aimed to determine the effect of garlic in comparison with Plavix on platelet aggregation. Materials ...

BACKGROUND AND OBJECTIVES P-selectin ctin has been implicated in important platelet functions. However, neither its role in thrombus formation and cardiovascular disorders nor its suitability as a therapeutic target structure is entirely clear. DESIGN AND METHODS Platelet aggregation was assessed in complementary in vitro settings by measurements of static aggregation, standardized aggregomet...

protein aggregation and precipitation is associated with many debilitating diseases including alzheimer's, parkinson's, and light-chain amyloidosis. β-casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

School Quality, Educational Attainment and Aggregation Bias Data from 31 countries participating in the Programme for International Student Assessment (PISA) is used to estimate education production functions for reading literacy. The analysis suggests that the probability of finding statistically significant and correctly signed class size effects increases the higher the level of aggregation ...
