Purpose: This paper tries to qualitatively present the issues related to axes of development in digital libraries, including human force, content, services, and technology, and provide a clear viewpoint in this regard by considering all existing aspects. Methodology: In this paper, all existing resources were used. Through citation (library) method, the related literature was studied and, besi...
In this work we present novel axes-based visualizations that can be used to explore and analyze multivariate time series data. We propose different types of interactive axes, which in turn can be used to compile novel 3D axes arrangements. The proposed axesbased visualizations utilize an exposed central time axis around which axes representing time-dependent attributes are arranged. Each depend...
We investigate alignments between the spin axes of cosmic voids and the principal axes of nearby superclusters using the Millennium Run simulation of a ΛCDM cosmology. The concept of void spin was first introduced by Lee and Park in 2006 to quantify the tidal effect on voids from the surrounding matter distribution. Our numerical analysis reveals that the void spin axes are strongly aligned wit...
a r t i c l e i n f o a b s t r a c t Gmat 2.1 is a program able to compute the rovibrational G matrix in different molecule-fixed axes extending the capabilities of Gmat 1.0. The present version is able to select optimal molecule-fixed axes minimizing the pure rotational kinetic elements, the rovibrational kinetic elements or both simultaneously. To such an end, it uses a hybrid minimization a...
The effect of temperature change on dynamic performances of an industrial robot with six axes of freedom is studied in this paper. In general, the strain and stress are produced not only by the external exciting force, but also by temperature change. The strain energy that is caused by temperatureThis paper describes how the temperature variation effects the dynamic performance of an indu...
BACKGROUND the complex motions of the wrist are described in terms of four anatomical directions that are accomplished through the multiple articulations of the carpus. With minimal tendinous insertions, the carpus is primarily a passive structure. This emphasizes the importance of its mechanical properties, which few studies have examined to date. The purpose of the present study was to determ...

A new control approach to position synchronization of multiple motion axes is developed, by incorporating cross-coupling technology into adaptive control design. The strategy is to stabilize position tracking of each axis while causing differential position errors between each axis and the other two axes converge to zero. If motions of every pair of axes are synchronized, motions of all axes ar...
We investigated if visual direction-selective neurons in the pretectal area (APT) of goldfish (Carassius auratus auratus) preferred visual stimuli resulting from rotations around axes corresponding to the best responsive axes of the semicircular canals [optic flow that is consistent to a maximal activation of the horizontal canal pair (yaw), to a maximal activation of the right anterior/left po...
Technology can provide safety in physical practices and improving the performance of these activities, so manufacturing of equipments for these purposes has been considered widely. The aim of the present paper was design and fabrication of three-axis accelerometer. hree acceleration sensors, three gyroscopes for angular velocity measurement, a microcontroller for converting analog data to ...
