An augmented reality (AR) technology enables to show an additional information by superimposing virtual objects onto the real world. The AR technology is gradually used in the learning environment for observing unseeable objects. Observation is the important process of inspecting a target object with significant details. It forms the basic of all scientific knowledge in education. However, ther...

closed kinematic chains and 1 2 ) as a force constrainad mechanical system working on the samo object simultaneously. based on a feedback linearization and simultaneous output docoupling technique. Applying a nonli ear faodback and a nonlinear coordinate transformation, the complicated model of the multiple robot arms in either formulation is converted into a linear and output decoupled system....

Studies with fluoroquinolones have led to a general method for restricting the selection of antibiotic-resistant mutants. The strategy is based on the use of antibiotic concentrations that require cells to obtain 2 concurrent resistance mutations for growth. That concentration has been called the "mutant prevention concentration" (MPC) because no resistant colony is recovered even when >10(10) ...

Augmented reality (AR) has been widely applied in our lives. An AR tag is usually used and stacked on products for sake of being detected and recognized easily. With the recognized pattern, the AR system thereby can superimpose the corresponding virtual object on the AR tag. The AR tag, however, distort the perception of products. In this study, we proposed a mechanism that integrates the AR ta...

Introduction Since the mid-1990s the search for extra-solar, terrestrial planets (called ‘exo-planets’ hereafter for brevity), and the possibility of life on them has received much attention. Both ESA and NASA are studying space-based telescopes that will enable the scientific community to conduct such a search. The most promising technology that will allow the detection of exoplanets and the s...

On the one hand any effective action of the QCD, involve, at least in principle, a tower of hadronic fields of all spins; on the other hand the front form of the field theory has emerged as an appropriate framework to investigate the high energy behaviour of many systems. Motivated by these simple considerations we present a systematic formalism which explicitly provides the front form fields a...

In this paper, we propose a system to achieve Augmented Reality (AR) on a smartphone. In this system, we assume a fixed RGB-D camera connected to a server is installed in the environment, and perform AR based on the 3D environment shape got by the RGB-D camera in real-time. On the smartphone side, it sends the image captured by its camera, and receives the output image processed to perform AR b...

The aim of the article is to determine whether so and /'( fulfil distinct discourse-building roles, in their predicateand proposition-anaphoric guise. Is the choice between them determined by the syntactic or semantic nature of their 'antecedent', or of the context in which the choice between them is to be made? Or do they in fact themselves determine their 'antecedent' (or at least superimpose...

Interferometer Setup The Twyman–Green interferometer (Figure 1) is a special configuration of the well-known Michelson interferometer with optics that superimpose the images of the object and the reference planes. Polytec engineers use this interferometer and place a CCD image sensor like those used for digital photography at the point where the two images are superimposed. A broadband “white-l...

The earthquake is usually a big disaster that causes several death and mortalities. Post earthquake crisis is an important situation for management. The recent 2015 Nepal earthquake is one of the most destructive earthquakes in history. In post earthquake crisis, lack of facilities, destroyed of infrastructures and limitation of transportation can be expected. This can superimpose the situation...
