Small satellite missions are becoming increasingly complex as scientists and engineers propose to utilize them to accomplish more ambitious science and technology goals. Small satellites such as CubeSats are challenging to design because they have limited resources, coupled subsystems, and must operate in dynamic environments.
Right skewed data is available in the field of health science, biological science, epidemiological science and others. This paper assessed some existing procedures for testing the difference of means of two right skewed populations. A Monte Carlo simulation study has been conducted to compare the performance of the test statistics in the sense of empirical size and power of the selected tests. Based...
As a kind of Chinese culture, Chinese Kung-fu has been very popular in movies and TV programs and attracted the interest of people all over the world. The paper address the problem to recover Chinese Kung-fu from video sequence for further use in computer games. Human motion capture for animation and VR has reached a level of capturing real motion data from people using various visual and non-visual...
Hidden Markov model used in multiple alignment is a new field of bioinformatics. Nowadays large amount of data about protein sequence structures have been obtained. Tranditional methods of protein analysis are no longer used. biologists have updated their research methods with computer technology and statistics, which can deal with large amount of data. Hidden Markov model can be used to distinguish...
With the mathematical theory of Yuanjian, this paper proposes a mathematical formulation of the secondary structure of nucleic acid The goal of this article is to represent and interpret the genetic structure at the molecular level mathematically, and to explore the fundamental principle of molecular biology and further research the disease mechanism at the system level. Propositions based on the...
This paper deals with a Luenberger observer for a class of Takagi Sugeno (TS) descriptor systems. This kind of systems represents many fields as chemical, robotics and electrical systems. A new approach is used to study the stability analysis of the Takagi Sugeno descriptor observer system. The state estimation error leads to formulate linear matrix inequalities (LMIs) which solve the observer gains...
We employed the Random Matrix Theory (RMT) to construct a nearly unbiased estimator of true error rate of linear discriminant analysis (LDA) with ridge estimator of inverse covariance matrix in the multivariate Gaussian model and in small-sample situation. In such a scenario, the performance of the constructed estimator, as measured by Root-Mean-Square (RMS) error, shows consistent improvement over...
Optimizing problems are problems of finding the best feasible solution in a set of solutions. Multi Battalion Search Algorithm (MBSA) is a heuristic algorithm used to solve optimization problems by simulating battlefield strategies and tactics to find optimal or near optimal solutions. The strategy of search in MBSA consists of dividing search space into several battalions or cells. The algorithm...
Stage structured based population models have found many applications in the recent years. In this paper an age structured population model is developed and implemented to study the trends in the computer and video game playing population of US. The entire game paying population is divided into three compartments on the basis of the age group to which they belong. After simulating the mathematical...
Two big earthquakes happened in October 2011 in one of the city at Eastern Region of our country and all educational system affected negatively and the university in the city has to break down its education. In order to solve this problem, it was decided to use Moodle to continue education at the university. All students and instructors except for the medical and dental faculties were obliged to use...
Artificial immune systems (AIS) utilize isolated mechanisms of the immune system to build specific algorithms. However, the immune system functions as a holistic system to protect the human body. In the same way, we propose to integrate independent AIS algorithms to build holistic AIS, namely unified artificial immune system (UAIS). It pushes AIS research to a higher level. We expect to see more powerful...
It's very important to investigate the effect of crustal movement on water cycle and related land surface processes in the laboratory environment for geographic researchers, especially the influence of tectonic deformations on the basin, the river course and the estuary. In this paper, a crustal movement simulation system (CMSS) is proposed, including the mechanical design and related control system...
A novel analysis method for systems engineering based on wargaming technology is proposed. First, the essential factors and procedures of wargaming are introduced. Then, the systems engineering method based on wargaming is analyzed. At last, the systems modeling, simulating, and analyzing procedure is described in details by illustrating a living example. The characteristics and advantages of this...
We present an approach to use high level data from hand X-Rays in postero-anterior (PA) view for synthesizing the animation and deformation of 3D hand models. We discuss our approach to model muskuloskeletal deformations caused by rheumatoid arthritis (RA) and show how this could be used to animate progressions 1 of RA from early to late stage. We also discuss a potential use case of our method as...
In this work, we propose a computer model for simulating and studying crowd evacuation behavior, and apply it to study the evacuation of a soccer stadium. Our model uses 2D cellular automata defined over multiple grids that represent different levels of the simulated environment. A pedestrian moves from a given grid cell to another by analyzing multiple movement options and resolving conflicts with...
In the centenary year of Turing's birth it is appropriate to explore the relationship between Computational and Human Intelligence along the path that he proposed over 60 years ago. In many way, he saw clearly what the issues were, although there were some that he missed or underestimated. We approach the problem of Human-level Computational Intelligence from two perspectives: the aspects of human...
This paper describes an approach for the design of coursework in crash injury biomechanics based on a remote collaborative learning environment. Virginia Tech and Wake Forest University (VT-WFU) have formed the Center for Injury Biomechanics, a unique partnership, which offers a graduate curriculum in crash injury biomechanics to prepare graduate biomechanics students to address this critical public...
Hadoop MapReduce has become one of the most popular tools for data processing. Hadoop is normally installed on a cluster of computers. When the cluster becomes undersized, it can be scaled by adding new computers and storage devices, but it can also be extended by real or virtual resources from another computer cluster. We present a utilization of the MapReduce paradigm on a Hadoop installation extended...
By using molecular dynamics (MD), we study the course of behavior and constitution of lipid vesicle in order to be able to recreate the measured results obtained in previous experiments. Simulated lipid vesicles are composed of thousands of DSPC lipid molecules. All preformed vesicles have a mean radius of around nine nanometers and interact with the watery environment. We use coarse grain molecular...
