We have conducted a systematic survey for z $<$ 0.04 active Galactic nuclei (AGNs) that may changed spectral class over the past decade. use SkyMapper, Pan-STARRS and V\'eron-Cetty & V\'eron (2010) catalogue to search entire sky these ``changing-look'' AGNs using variety of selection methods, where has coverage 3$\pi$ steradians (sky north Declination $-30^\circ$) SkyMapper $\sim$ 21,000$~\rm{d...

The informality of Strategic Research Project Management procedures is still a reality in several health science and technology institutions Brazil, with recognized negative impact on innovation management. objective this work to verify the scientific academic production related methodologies strategic management research projects databases journals last 10 years, period from 2011 2021. methodo...

Two potential sources of systematic variation in output from Mefar dosimeters, the system used in the European Community Respiratory Health Survey (ECRHS) study have been evaluated: individual nebulizer characteristics and dosimeter driving pressure. Output variation from 366 new nebulizers produced in two batches for the second ECRHS were evaluated, using a solute tracer method, at a fixed dri...

Given the basic parameters of a cosmic shear weak lensing survey, how well can systematic errors due to anisotropy in the point spread function (PSF) be corrected? The largest source of error in this correction to date has been the interpolation of the PSF to the locations of the galaxies. To address this error, we separate the PSF patterns into components that recur in multiple exposures/point...

The Department of Archaeology at Siena has been engaged for several decades in the testing of new methodologies, new approaches and new instruments for construction of the archaeological record. In relation to landscape archaeology and in particular with the South Tuscan landscapes the low level of visibility and heavy clay soils have directed us towards those techniques of remote sensing that ...

This paper considers the design of acoustic surveys for estimating the mean abundance of spatially correlated populations. We examined how the choice of survey design affects the bias and precision of the sample mean as an estimator of mean abundance. Further, we investigated three different ways of estimating the error variance of the sample mean: the pooled within strata variance and two geos...

Electronic Nose is one of the most advance device in the field of sensor technology. It is responsible for the automated detection and classification of gases, odors and vapors. This paper reviews the three components of Electronic Nose i.e. sample handling, detection system, data processing system. It outlines the range of sensors their principles, advantages and disadvantages. It describe the...
