The norm (length) of a vector is the distance from its intitial point to its terminal point and is nonnegative. ■ Multiplication of a nonzero vector by a nonzero scalar results in a vector that is parallel to the original. ■ For any given nonzero vector, there is a unique unit vect...

Each vector a has a counterpart negative vector –a so that a + –a = 0. [13]+[−1−3]=[00]=0 We shall have occasion to refer to one or more of these properties quite frequently in subsequent dicussions. 2.3.4 Scalar Multiplication of a Vector Assume we have some real number...
In this analysis, each resonator can be regarded as a discrete mass-spring system coupled at a single point with the bar having the nominal mechanical impedance z0. We will show that, owing to the installation of the paired resonators, the effective impedance z of the region that they surrou...
model, a Poisson model was implemented at a first stage to determine whether the data presented over-dispersion; finally, the performance of the proposed model was compared against some base models: Negative Binomial (NB), Zero-Inflated Poisson (ZIP), and Zero-Inflated Negative Binomial (ZINB)....
which leads to the permittivity of the accumulation layer changing from a positive one to a negative one. For applied bias values larger than 3.0 V, the permittivity of the accumulation layer is negative, similar to metal. In the case of an applied bias around 2.6 V,εaccis close to zero...
Scopes may be declared as 'unstacked', meaning that they do not appear in the sequence of numbers, either positive or negative. A unstacked scope with no alias could not be referred to at all and is thus disallowed. A scope may be recast with a new alias, stacked or unstacked, with...
The data were found to have excess zeros (35%); thus several count data models such as Poisson, Negative Binomial, Zero Inflated Poisson, Zero Inflated Negative Binomial and Hurdle regression models were modeled and fitted. From the exploratory analysis the results showed that among those eligible...
Pre-shaped microbeams, curved or inclined, are widely used in MEMS for their interesting stiffness properties. These mechanisms allow a wide range of positive and negative stiffness tuning in their direction of motion. A mechanism of pre-shaped beams wit
