A quick and very sensitive method is proposed for the determination of the insecticide carbaryl, following transformation in 1-naphthol, using solid-phase fluorescence excited by a pulsed nitrogen laser and detected with a charge-coupled device. Carbaryl is hydrolized in an alkaline medium resulting in 1-naphthol. This hydrolysis product is fixed on QAE Sephadex A-25 gel at pH 11.20. The fluore...

Symbolic data are usually composed of some categorical variables used to represent discrete entities in many real-world applications. Mining symbolic is more difficult than numerical due the lack inherent geometric properties this type data. In paper, we use two kinds kernel learning methods create a estimation model and nonlinear classification algorithm for By using smoothing method, construc...

Abstract Driven by digital technologies, manufacturers aim to tap into data-driven business models, in which value is generated from data as a complement physical products. However, this transformation can be complex, different archetypes of models require substantially and technical capabilities. While there are manifold contributions research on capability development, an integrated aligned p...

Image classification and retrieval systems have gained more attention because of easier access to high-tech medical imaging. However, the lack of availability of large-scaled balanced labelled data in medicine is still a challenge. Simplicity, practicality, efficiency, and effectiveness are the main targets in medical domain. To achieve these goals, Radon transformation, which is a well-known t...

Antiferroelectrics (AFE) can exhibit a “shape memory function controllable by electric field”, with huge isotropic volumetric expansion (0.26%) associated with the AFE to Ferroelectric (FE) phase transformation. Small inverse electric field application can realize the original AFE phase. The response speed is quick (2.5 ms). In the Pb0.99Nb0.02[(Zr0.6Sn0.4)1-yTiy]0.98O3 (PNZST) system, the shap...

background: according to quality transformation of services during the time, the quality requirements and standards also change and recognition of these requirements and transformation process can assist in recognizing the quality dimensions of services. the aim of this research was to explain the transformation process, requirements and quality dimensions of services in hospitals.   methods: t...
