Simulation is a useful tool for engineering systems, and it is used in numerous and diverse fields. Simulation of large systems can result in better designs, and make the design process more efficient. One important use of simulation lies in comparing different simulation models that represent competing or alternative designs before the actual deployment and implementation. Simultaneous Simulat...

This paper presents a new data representation known as Dual FiXedpoint (DFX), which employs a single bit exponent to select two different fixedpoint scalings. DFX provides a compromise between conventional fixed-point and floating-point representations. It has the implementation complexity similar to that of a fixed-point system together with the improved dynamic range offered by a floating-poi...

Pairwise classification has many applications including network prediction, entity resolution, and collaborative filtering. The pairwise kernel has been proposed for those purposes by several research groups independently, and become successful in various fields. In this paper, we propose an efficient alternative which we call Cartesian kernel. While the existing pairwise kernel (which we refer...

A new way of constructing efficient semiparametric instrumental variable estimators is proposed. The method involves the combination of a large number of possibly inefficient estimators rather than combining the instruments into an optimal instrument function. The consistency and asymptotic normality is established for a class of estimators that are linear combinations of a set of √ n– consiste...

Suffix trees are versatile data structures that are used for solving many string-matching problems. One of the main arguments against widespread usage of the structure is its space requirement. This paper describes a new structure called suffix vector, which is not only better in terms of storage space but also simpler than the most efficient suffix tree representation known to date. Alternativ...

The invariant feature detectors are essential components in many computer vision applications, such as tracking, simultaneous localization and mapping (SLAM), image search, machine vision, object recognition, 3D reconstruction from multiple images, augmented reality, stereo vision, and others. However, it is very challenging to detect high quality features while maintaining a low computational ...

This paper presents a novel, promising approach that allows greedy decision tree induction algorithms to handle problematic functions such as parity functions. Lookahead is the standard approach to addressing difficult functions for greedy decision tree learners. Nevertheless, this approach is limited to very small problematic functions or subfunctions (2 or 3 variables), because the time compl...

It is increasingly being used to transmit data on networks but is a verbose format and needs an efficient encoding to send relatively large amounts of data efficiently since XML became an official recommendation of the World Wide Web Consortium (W3C) in 1998. This requirement is particularly important, which is most for attractive to wireless data communications. It is a common technical challe...

MATERIALS AND METHODS: Using open-source CAD modeling software, we developed a customizable prosthetic eye model. The eye can be customized within the following parameters: shape, height, length, width, thickness, concavity, iris diameter, and pupil diameter. The customization process is user friendly, requiring numeric inputs or parametric adjustments. The final model is exported and processed...
