Abstract In this paper, we will prove some fundamental properties of the power mean operator $$ \mathcal{M}_{p}g(t)= \biggl( \frac{1}{\Upsilon(t)} \int _{0}^{t} \lambda (s)g^{p} ( s ) \,ds \biggr) ^{1/p},\quad\text{for }t\in \mathbb{I}\subseteq \mathbb{R}_{+}, M p g</mml:mi...

OBJECTIVE To evaluate the accuracy of prediction of birth weights from body weights of newborns till six days after birth. DESIGN Prospective follow-up. SETTING Four villages near Hyderabad. METHODS Weights of 47 newborns were recorded daily from the day of birth for seven days. The birth weights were regressed on the weights of the babies taken on the 2nd day to the 7th day. Specificity ...

One popular feature type in speech recognition is based on linear transformations of sequences of cepstral feature vectors. In general the transformation is generated in two steps: first a transformation like linear discriminant analysis (LDA) or heteroscedastic linear discriminant analysis (HLDA) is used to maximize separation between classes and reduce the dimensionality, followed by a decorr...

Linear codes have been an interesting subject of study for many years. Recently, linear codes with few weights have been constructed and extensively studied. In this paper, for an odd prime p, a class of three-weight linear codes over Fp are constructed. The weight distributions of the linear codes are settled. These codes have applications in authentication codes, association schemes and data ...
