In recent years evolution of level sets of two-dimensional functions or images in time through a partial differential equation has emerged as an important tool in image processing. Curve evolutions, which may be viewed as an evolution of a single level curve, has been applied to a wide variety of problems such as smoothing of shapes, shape analysis and shape recovery. We give a stochastic inter...

Elliptic curve cryptography is known for its complexity due to its discrete logarithm problem, and this gives advantage to the system used since the formula developed using this concept is hard to break, therefore this criteria has given mathematicians a courage to explore this area of research. Earlier in [10], we have showed a new method for imbedding plaintexts using complementary elliptic c...

Advocacy for a fully circular economy of electronic products has intensified in response to relentless demand materials and the toxic legacy waste (e-waste). Convergence innovation resource recovery, regulatory policies, consumer participation is needed bend curve electronics revolution toward economy.

To provide supplementary oil recovery after the primary and secondary processes, enhanced oil recovery (EOR) techniques are introduced. Carbonated water injection (CWI) as an EOR method can improve sweep efficiency and the risk of gas leakage. On the other hand, the interfacial tension (IFT) is one of the key factors which can affect fluid displacement during the process of CWI greatly. Therefo...

A new strategy is proposed for verifying if recovery factor is constant and independent of the real analyte content of samples. A signal-recovery function has been developed on the basis of measurement of spiked test samples before and after a pre-treatment step and considering, as starting point, a recent IUPAC recommendation which distinguishes between two terms--recovery factor, R, and appar...

The assessment of the recovery factor with the analyte concentration in meat samples has been studied for the determination of organochlorine and organophosphorus pesticides in meat by gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS). For that purpose, recent IUPAC recommendations, which distinguishes between two terms, recovery factor and apparent recovery, have been followed....

objective: to evaluate the current scientific evidence for the applicability, safety and effectiveness of pathways of enhanced recovery after emergency surgery (eras). methods: we undertook a search using pubmed and cochrane databases for eras protocols in emergency cases. the search generated 65 titles; after eliminating the papers not meeting search criteria, we selected 4 cohort studies and ...

The time evolution of a Munch pressure-flow translocation system is calculated using a numerical computer method. Results are obtained for the time course of the system variables following application of a large resistance in the translocation path, intended to simulate a cold block. The resistance factor required to produce translocation inhibition indicates that even moderate inhibition is pr...
