The frequency dependence of the ultrasonic backscattering coefficient (BSC) was studied to assess the level of red blood cell (RBC) aggregation. Three monoelement focused wideband transducers were used to insonify porcine blood sheared in a Couette flow from 9 to 30 MHz. A high shear rate was first applied to promote disaggregation. Different residual shear rates were then used to promote forma...

The feasibility of detecting red blood cell (RBC) aggregation with photoacoustics (PAs) was investigated theoretically and experimentally using human and porcine RBCs. The theoretical PA signals and spectra generated from such samples were examined for several hematocrit levels and aggregates sizes. The effect of a finite transducer bandwidth on the received PA signal was also examined. The sim...

Automated reasoning is becoming crucial for information systems. Building one uniform decision support system has become too complicated. The natural approach to divide the task and combine results from different subsystems into answer. It basic idea behind approach, where solution a composition of multiple subsystems. In this paper, main emphasis on establishing theoretical framework that comb...

Classes The property isAbstract indicates that a given class specification cannot be instantiated directly. This construct mainly introduces a uniform treatment of related real-world things in problem analysis. According to our modelling experience, this adornment is often used when similar structural as well as behavioural features of classes are combined into a generalisation. The specialised...

α-synuclein (αS) is a protein involved in neurotransmitter release in presynaptic terminals, and whose aberrant aggregation is associated with Parkinson's disease. In dopaminergic neurons, αS exists in a tightly regulated equilibrium between water-soluble and membrane-associated forms. Here we use a combination of solid-state and solution NMR spectroscopy to characterize the conformations of αS...

A dramatic increase of event monitoring capabilities by wireless sensors requires new, more sophisticated, event correlation over time and space. This new paradigm implies composition of events in ubiquitous computing environments and event Correlation will be a multi-step operation from event sources to final subscribers, combining information collected by wireless devices into higher level in...

Object-Relational Database (ORDB) is increasingly popular as the database storage. Its popularity is based on its ability to capture the object-oriented modeling semantic and the maturity of relational implementation. Many works have proposed the design method for ORDB. The design includes different data structures and relationships. One type of relationship is composition. It is not the same a...

in this paper, we study the finitely many constraints of the fuzzyrelation inequality problem and optimize the linear objectivefunction on the region defined by the fuzzy max-product operator.simplification operations have been given to accelerate theresolution of the problem by removing the components having noeffect on the solution process. also, an algorithm and somenumerical and applied exa...

In this paper, we describe a semantic middleware which aims to provide ubiquitous computing applications with high level contextual knowledge. The proposed middleware architecture is designed around service agent entities, offering transparent and reusable services for context semantic discovery, capture and aggregation. Aggregation of contextual knowledge is modeled using services composition ...
