BACKGROUND The Internet Addiction Test (IAT) by Kimberly Young is one of the most utilized diagnostic instruments for Internet addiction. Although many studies have documented psychometric properties of the IAT, consensus on the optimal overall structure of the instrument has yet to emerge since previous analyses yielded markedly different factor analytic results. OBJECTIVE The objective of t...

Most engineers are (indirectly) trained to be "feedforward thinkers" and they immediately think of "model inversion'' when it comes to doing control. Thus, they prefer to rely on models instead of data, although feedback solutions in most cases are much simpler and more robust.

chaos theory discusses unstable and non-periodic behavior of non-linear fluctuating dynamicsystems. since evaporation level variations of lakes have a dynamic identity, chaos theory can have a uniquerole in collecting data of these variations. therefore it is an important and challenging problem in the field ofplanning and qualitative and quantitative management of urmia lake to verify whether ...

Although it is generally accepted that blood has never been safer than today, transfusion-associated side effects, particularly infective, still occur. Unlike screening strategies, pathogen reduction technologies offer a new approach to increase blood safety by actively/directly targeting possible, also emerging pathogens or donor leukocytes. Advanced technologies for cellular blood products li...

In a search graph the node's value is dependent on the path leading to it. Diierent paths may lead to diierent values. Hence, it is diicult to determine the value of any node unambiguously. The problem is known as the graph-history-interaction (GHI) problem. This report provides a solution for best-rst search. First, we give a precise formulation of the problem. Then we review all important ear...

We read with great interest the paper of Puma et al. [1], in which they propose an external longitudinal titanium support after sternochondroplasty for severe asymmetric pectus excavatum repair. Pectus excavatum has probably been the chest deformity with the largest number of proposed techniques for its correction over the years. The very interesting solution proposed by Dr Puma gives rise to a...

This paper furnishes two classes of methods for calculating the best approximate solution of an operator equation in Banach spaces, where the operator is bounded, linear and has closed range. The best approximate solution can be calculated by an iterative method in Banach spaces stated in terms of an operator parameter. Specifying the parameter yields some new and some old iterative techniques....

Acquiring the complete surface geometry of an object using a range scanner invariably requires that multiple range images be taken of it from different viewpoints. An algorithm is presented which solves the “next best view” (NBV) problem: determine the next position for the range scanner given its previous scans of the object. As part of a complete surface acquisition system the scanner’s next ...

This paper discusses analytical and numerical issues related to elliptic equations with random coefficients which are generally nonlinear functions of white noise. Singularity issues are avoided by using the Itô-Skorohod calculus to interpret the interactions between the coefficients and the solution. The solution is constructed by means of theWiener Chaos (Cameron-Martin) expansions. The exist...
