abstract This paper describes a novel approach to nd a tighter bound of the transformation of the Min-Max problems into the one of Least-Square Estimation. It is well known that the above transformation of one problem to the other can lead to the proof that their target functions linearly bound each other. However, this linear bound is not a tight one. In this paper, we prove that if we transfo...

This study investigates various models to represent the gross geometric shape of the Moon. Asymmetric polyaxial geometric modelsnamely three-, fourand six-axial lunar figure are compared and contrasted with the axially symmetric three-axis ellipsoidal model derived from Chang'e 1 and SELENE laser altimetry data. All solutions confirm a hydrostatically stable lunar shape shifted with respect to ...

This study investigated infant social looking in a social referencing procedure with mothers and strangers. Sixty-one infants and their mothers participated when the infants were 18 and 24 months old. The frequency and latency of looking toward each adult when the baby encountered remotecontrolled ambiguous toys were measured. Mothers and strangers (female experimenters) expressed positive or n...

The problem of determining the optimal warranty period, assumed to coincide with the manufacturer’s lower specification limit for the lifetime of the product, is addressed. It is assumed that the quantity sold depends via a Cobb–Douglas-type demand function on the sale price and on the warranty period, and that both the cost incurred for a non-conforming item and the sale price increase with th...

Background: Anthropometry is a branch of anatomy. One of the important parts of anthropometry is cephalometry, which is characterized by anatomical dimensions of the head area. The aim of this study was to investigate the relationship between brain volume, weight, and IQ in children. Methods: This descriptive-analytical study was performed on 300 students...

INTRODUCTION Over 70 million people in Europe and >50 million people in the USA are reported to experience tinnitus (the sensation of noise in the absence of any corresponding sound source). Tinnitus is a multidimensional concept. Individual patients may report different profiles of tinnitus-related symptoms which may each require a tailored management approach and an appropriate measure of the...

Introduction: The objective of this study was to gather information about normal occlusion and arch dimensions in the primary teeth of the children belonging to an Iranian population. Methods: This descriptive cross-sectional study was performed on 68 children from the city of Mashhad in the 3-5 age range. Dental arch dimensions, interrelationships of primary canine and second molars, overbite ...
