The design of nonlinear controllers for mechanical systems has been an ex tremely active area of research in the last two decades. From a theoretical point of view, this attention can be attributed to their interesting dynamic behavior, which makes them suitable benchmarks for nonlinear control the oreticians. On the other hand, recent technological advances have produced many real-world engineering applications that require the automatic con trol of mechanical systems. the mechanism for de Often, Lyapunov-based techniques are utilized as veloping different nonlinear control structures for mechanical systems. The allure of the Lyapunov-based framework for mechanical system control de sign can most likely be assigned to the fact that Lyapunov function candi dates can often be crafted from physical insight into the mechanics of the system. That is, despite the nonlinearities, couplings, and/or the flexible effects associated with the system, Lyapunov-based techniques can often be used to analyze the stability of the closed-loop system by using an energy like function as the Lyapunov function candidate. In practice, the design procedure often tends to be an iterative process that results in the death of many trees. That is, the controller and energy-like function are often constructed in concert to foster an advantageous stability property and/or robustness property. Fortunately, over the last 15 years, many system the ory and control researchers have labored in this area to produce various design tools that can be applied in a variety of situations.
The Atlas of Climate Change—Based on SEAP-CMIP5" is intended to satisfy readers’ curiosity: how will our climate system change over the next 100 years? It is the first showcase for the state-of -the-art earth system models that released their CMIP5 simulations for the IPCC AR5.The atlas focuses on both the past climate system change from 1850 and the projection of the future climate system change to 2100 using the RCP2.6, RCP4.5 and RCP8.5 scenarios based on climate models. This provides the research and application community interested in the impact of climate change on fields such as agriculture, ecosystem, environment,water resources, energy, health, economy, risk governance and international negotiation, etc. with the newest climate change projection information. Additionally, the atlas will show the historical responsibility of the developed/developing countries and possible contributions to the mitigation of climate change according to their pledge of GHG emission reduction after the Cancun Agreement as an extension numerical experiment to CMIP5 with NCAR’s CESM1.0. The authors will update this atlas after future releases of CMIP5 model outputs and update the figures in the second edition of the atlas in 2012-2013. Both Prof. Wenjie Dong and Yan Guo work at the Beijing Normal University, China. Prof. Fumin Ren works at the China Meteorological Administration, China. Prof. Jianbin Huang works at the Tsinghua University, China.
Changing China has become an important factor in influencing the value of human society as a whole. However, in order to truly achieve substantive change in Chinese society, it is necessary to achieve a new understanding of the civilizational order of human society. Although there are already various ideas and theories guiding and influencing the real world, all kinds of disputes and confusion are emerging. The endless disputes over various interests and concerns over various values are all urging a rebirth of the cognitive values of human civilization! Although I have the desire to contribute to the advancement of human civilization, I am not able to do so alone. Although I have spent most of my life exploring, I have not been able to meet the needs of reality. In recent years, I have been fortunate enough to live in the United States, where I enjoy a great deal of freedom, and I have been able to express some of my initial understanding publicly. Although my conceptualization of these values is not formally acknowledged by relevant authorities or experts, I feel it is important to articulate and record these ideas in the hope that they will help influence people's perception of the real world and improve it, especially in Chinese society!

This monograph introduces the overall systems architecture and patterns for data streams that enables autonomy for marine robots towards environmental sensing applications. It proposes a concept called cyber-maritime cycle and surveys its use as a recent development in the marine robotic community.
