Current–voltage (I–V) curve measurement is an essential performance characterization technique for laser power converters (LPCs). Choosing appropriate scan time can effectively avoid problems in the test process that lead to inaccurate data. We analyzed I–V error of a GaAs LPC relation by building system LPCs. A method determining optimal time, defined as period containing upper limit and lower...

In the attention-deficit hyperactivity disorder (ADHD) study, children are prescribed different stimulant medications. The height measurements recorded longitudinally along with medication time. Differences among patients captured by parameters suggested Superimposition Translation and Rotation (SITAR) model using three subject-specific to estimate their deviation from mean growth curve. this p...

In many application domains involving shapes and curves, polygonal curve simplification is an important part of the computer analysis processes. In this work, we have developed asymptotically optimal and linear-time algorithms to approximate a polygonal curve by another polygonal curve whose vertices are a subset of the vertices of the original one. The algorithm developed in this paper can be ...

Given two elliptic curves over a finite field having the same cardinality and endomorphism ring, it is known that the curves admit an isogeny between them, but finding such an isogeny is believed to be computationally difficult. The fastest known classical algorithm takes exponential time, and prior to our work no faster quantum algorithm was known. Recently, public-key cryptosystems based on t...
