there have been many productive methods developed so far for optimization of multiple response surface (mrs) problems. this paper tends to review the most seminal approaches in mrs and discuss the strength and weakness of each of the approaches through existing aspects in mrs. a numerical example is included to compare results by different methods. finally some of the prominent areas for future...

S U M M A R Y Wavelet analysis for filtering is used to improve estimation of gravity variations induced by Chandler wobble. This method eliminate noise in superconducting gravimeter (SG) records with bandpass filters derived from Daubechies wavelet. The SG records at four European stations (Brussels, Membach, Strasbourg and Vienna) are analysed in this study. First, the earth tidal constituent...

Sensory gating (SG), referring to an attenuated neural response to the second identical stimulus, is considered as preattentive processing in the central nervous system to filter redundant sensory inputs. Insufficient somatosensory SG has been found in the aged adults, particularly in the secondary somatosensory cortex (SII). However, it remains unclear which variables leading to the age-relate...

Starch (ST) is the main determinant of cassava root industrial quality and routinely quantified using specific gravity (SG) method, which simple but lacks precision. This study aimed to estimate dry matter (DM) ST content in nine modern genotypes SG method develop updated empirical equations that relate values with DM content. Two field experiments were conducted a randomized block design genot...

Abstract Brazilian potato production is based on cultivars originating from the USA and Europe; however, these were developed under different environmental conditions than those found in Brazil. The aim of this study was to evaluate adaptability stability 18 clones (MLG), by Universidade Federal de Lavras, four six environments state Minas Gerais, following traits evaluated: marketable tuber yi...

BACKGROUND AND AIM: Sesame has a high content of calcium. Regarding to the lack of adequate data about its remineralizing potential, we conducted this study to evaluate the surface hardness of enamel exposed to sesame extraction gel in comparison to artificial saliva and fluoride.METHODS: After mounting and polishing twenty-four caries-free human premolars, the baseline microhardness was record...

The objective of this work was to develop bioadhesive topical gel of Aceclofenac with the help of response-surface approach. Experiments were performed according to a 3-level factorial design to evaluate the effects of two independent variables [amount of Poloxamer 407 (PL-407 = X1) and hydroxypropylmethyl cellulose K100 M (HPMC = X2)] on the bioadhesive character of gel, rheological property o...

We investigate the system of D-dimensional hard spheres in D-dimensional space, where D>3. For the fluid phase of these hyperspheres, we generalize scaled-particle theory to arbitrary D and furthermore use the virial expansion and the Percus-Yevick integral equation. For the crystalline phase, we adopt cell theory based on elementary geometrical assumptions about close-packed lattices. Regardle...

Loblolly pine ( Pinus taeda L.) productivity over the past century has increased significantly from genetic improvements and more intensive management practices. The current study concludes a series of assessments loblolly growth/physiological responses to continuous resource treatments weed control (W), plus irrigation (WI), fertigation (WIF). Increment cores were analyzed by X-ray densitometr...
