the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...

Abstract—Keyword Search is known as a user-friendly alternative for structured languages to retrieve information from graph-structured data. Efficient retrieving of relevant answers to a keyword query and effective ranking of these answers according to their relevance are two main challenges in the keyword search over graph-structured data. In this paper, a novel scoring function is proposed, w...

We expect emerging nanotechnology substrates to consist of a vast number of small processing nodes that are randomly assembled, have defect rates as high as 30%, and have globally asynchronous communication. Directly constructing an architecture on such a substrate presents many challenges to a system designer. An alternative approach, that would ease the constraints faced by a nanotechnology a...

Signal processing and pattern recognition algorithms make extensive use of convolution. In many cases, computational accuracy is not as important as computational speed. In feature extraction, for instance, the features of interest in a signal are usually quite distorted. This form of noise justi es some level of quantization in order to achieve faster feature extraction. Our approach consists ...

Regardless of the application domain and deployment scope, the ability to retrieve information is critical to the successful functioning of any wireless sensor network (WSN) system. In general, information extraction procedures can be categorized into three main approaches: agentbased, query-based and macroprogramming. Whilst query-based systems are the most popular, macroprogramming techniques...

We explore theoretical uncertainties in the hydrodynamic description of relativistic heavy-ion collisions by examining full nonlinear causality conditions and quantifying second-order transport coefficients' role on flow observables. The impose physical constraints maximum allowed values inverse Reynolds numbers during evolution. Including additional gradient terms Denicol-Niemi-Moln\'ar-Rischk...

Content-based indexing and query has been considered as a powerful technique for accessing large visual information systems (databases and video servers). By extracting and indexing the visual contents of the images such as texture, color, and shape, users may search desired images by specifying the image contents directly. However, a practical and economical solution cannot afford extensive us...
