There is a significant dearth of time and qualified teachers to make 200 million adult illiterates of India spread across 22 Indian Languages literate and it would take massive effort to address the scale and variety challenges. In this paper, we summarize four and half years of our experience of analyzing and improving a decade-long technology to adult literacy problem. Based on this experience and...
Thin layers of material are commonly occurring structures in many modern integrated photonics devices. As the overall geometric complexity of these integrated structures increases, it is convenient to employ flexible full-wave numerical electromagnetic simulators for their design. In this paper we discuss and present a technique for embedding thin layer material responses into one such numerical technique,...
This paper extends a proposed new approach to deal with smart objects or smart mobile devices by proposing a middleware framework inspired by RNA mechanisms in molecular biology. This framework represents complex application scenarios of proximity-based federation of smart objects as catalytic reaction networks. Each catalytic reaction is modeled as an RNA expression from a DNA. We introduce smart...
Many people take it for granted that the college English teaching mode for “leaner autonomy” is nothing but to ask students to learn to self-study with the student-centered class teaching. In fact, the scientific college English teaching mode for “leaner autonomy” is not just the case at all. It is the product of modern high technology and the embodiment of the theory of “leaner autonomy” in college...
This paper evaluates the usefulness of different simulators developed in server system testing for a mobile application during 5 years, with the purpose of identifying the advantages and weaknesses of each simulation method in the given setup. The study found that simulation was used on almost every interface to external systems, and two factors that affected the usefulness of simulators over long...
Learner models are of great importance in the construction of intelligent tutoring systems. In this paper, after introducing intelligent tutoring systems and learner models, four kinds of classical learner models called Stereotypes Models, Overlay Models, Buggy Models and Constraint-Based Models and their properties are discussed in detail. Finally, we compare these four kinds of learner models in...
ICTs have a direct impact on the environment, consuming energy, materials and producing e-waste. But ICTs are the major enabling technology for mitigation of environmental impacts across all economic sectors. ICT applications and services can help limit energy use and material consumption. In other words ICTs can contribute in achieving more sustainable lifestyles, consumption and production. The...
In this work we present a versatile simulation tool for the batch processing of solar cell simulation by using Matlab and the wxAMPS console version. The wxAMPS console version gives a programming interface for other software to call the simulation kernel of wxAMPS, and Matlab provides a favorable platform to define the modeling process and design the data visualization. This method offers users a...
Radiometric image analysis methods heavily rely on reflectance models. Due to the complexity of real materials, methods based on simple models such as the Lambertian model often suffer from inaccuracy. On the other hand, more advanced models such as the Cook-Torrance model severely complicate the analysis problem. We tackle this dilemma by focusing on the low-frequency component of the reflectance...
Rarely do our embedded systems solutions exist in isolation. For the most part we enable a mechanical system. Our early prototype when first exercised in the laboratory will frequently appear to exhibit additional (unintended) behaviour from that of its well-behaved simulated design. We often ascribe that behaviour to the 'fragility' of the prototype, which may be typical of its mechanical attributes...
Molecular dynamics simulation is an important and powerful tool in studying physical and chemical properties of materials, in particular, at the nanoscales. Conventional molecular dynamics, as oppose to the ab initio molecular dynamics, adopts the Newton's second law to predict particle position in the next time step with the assistance of empirical interatomic potential to calculate the forces between...
In the immediate aftermath of unconventional emergencies, coordination process of the emergency resources involves many complex factors. How to model the coordination process of the emergency resources, to evaluate the decision performance of the process is among one of the most important issues in the real world. We employ the System Dynamics (SD) method to analyze the feedback mechanism and the...
Evolutionary computation has often been presented as a possible model for creativity in computers. In this theoretical paper, preparing for a series of experiments, evolution is discussed in the light of a theoretical model of human artistic process, recently presented by the author. Some crucial differences between human artistic creativity and natural evolution are observed and discussed, also in...
This paper proposes an effective forecasting framework for the Oilfield Class-A materials, which take a large scale of proportion in the total purchasing cost. Based on the ARIMA model in time series analysis method, the dynamic forecasting framework is constructed to make short-time price prediction for Class-A materials in Oilfield, which only needs a small sample set to obtain high prediction accuracy...
The need for the visual presentation of material is increasing. While static graphs, images and charts can convey information in a thorough manner, video is of greater demand. Whether it be a tutorial for a software package, an online course for training, or a presentation of research material, nothing surpasses video as a tool for delivering information to your audience. Traditionally video capture...
Parameter measurement of 3D soft tissue model is of great theoretical significance and application value in virtual surgery training simulation system. To solve the problems of existing soft tissue parameter measurement methods with high complexity, we propose a fast and effective parameter measurement method. We adopt a pillow as test material and exert pressure on it to simulate the parameter measurement...
The most outstanding feature of emergency distribution is time urgency. Decision maker should use less time to complete the distribution scheme which should guarantee the materials reach the emergency site with less time. At this time it is especially important to choose the optimal path in the decision-making process. This article builds up mathematical model which is based on the emergency logistics...
The complete stress-strain curve of rock is the mechanical property data which is used widely and the most elementary and important. But the material of rock is of special complex natural structure. It is very hard to obtain the complete and true performance data of rock by the common material tester which causes rock broken easily. This paper studies the rock mechanics tester intelligently controlled...
Gas transmission station is an important part of transmission system. How to effectively reduce the pressure loss inside the station and improve the transmission efficiency has become one of hotspots that pipeline operating companies pay much attention to. Sequential modular approach is proposed to realize the connection between devices and achieve a whole gas transmission station process simulation...
The Determinant Quantum Monte Carlo (DQMC) method is one of the most powerful approaches for understanding properties of an important class of materials with strongly interacting electrons, including magnets and superconductors. It treats these interactions exactly, but the solution of a system of electrons must be extrapolated to bulk values. Currently is state-of-the-art. Increasing...
