Challenge and Algorithm of Face Alignment Development

Face alignment is a key step in face recognition.The location of face feature points is located in the face image,and the difference between different faces is reduced by geometric transformation.This is the basic condition of face information processing,such as expression recognition,face tracking,head pose estimation and so on.Due to the interference of expression,illumination,shading and other factors,face alignment has a great challenge and is becoming the developmental direction.Different algorithms can solve different problems at different levels.Deep learning algorithm can solve the shortcomings of traditional algorithm,improve the accuracy of face alignment,and promote the development of face alignment.

Development of Trusted Network and Challenges It Faces

As the information network plays a more and more important role globally, the traditional network theories and technologies, especially those related to network security, can no longer meet the network development requirements. Offering the system with secure and trusted services has become a new focus in network research. This paper first discusses the meaning of and aspects involved in the trusted network. According to this paper, the trusted network should be a network where the network’s and users’ behaviors and their results are always predicted and manageable. The trustworthiness of a network mainly involves three aspects: service provider, information transmission and terminal user. This paper also analyzes the trusted network in terms of trusted model for network/user behaviors, architecture of trusted network, service survivability and network manageability, which is designed to give ideas on solving the problems that may be faced in developing the trusted network.

China's Sustainable Development Faces Serious Challenges

Facing tough critical challenges in the fields of population, natural resources and the environment, China has to handle uphill tasks during the 10th Five-Year Plan (2001- 05) period. Researchers at the Research Center for the National Situation of the Chinese Academy of Sciences (CAS) and Tsinghua University recently pinpointed these challenges. The following are some of their findings.

Chemical Safety as a Major Challenge for Developing Countries: Role of the International Program on Chemical Safety^1

Developing countries face a number of unique problems related to the hazards of chemicals. The WHO International Program on Chemical Safety may play a useful role by working jointly with Member Nations and such international organizations as FAO, UNEP. and ILO. (c)1990 Academic Press. Inc.

China’s Development Should Respond to The New External Challenges

The international financial crisis has entered its fifth year,the euro-zone sovereign debt crisis is still fermenting,world economic growth is weak,the future development of China is facing multiple challenges and its external environment for sustainable development strategy witnesses a number of risks and uncertainties.

The latest process and challenges of microwave dielectric ceramics based on pseudo phase diagrams

The explosive process of 5G communication evokes the urgent demand of miniaturized and integrated dielectric ceramics filter It is a pressing need to advance the development of dielectric ceramics utilization of emerging technology to design new materials and understand the polarization mechanism.This review provides the summary of the study of microwave dielectric ceramics(MWDCs)sintered higher than 1000℃ from 2010 up to now,with the purpose of taking a broad and historical view of these ceramics and illustrating research directions.To date,researchers endeavor to explain the structure-property relationship of ceramics with multitude of approaches and design a new formula or strategy to obtain excellent microwave dielectric properties.There are variety of factors that impact the permittivity,dielectric loss,and temperature stability of dielectric materials,covering intrinsic and extrinsic factors.Many of these factors are often intertwined,which can complicate new dielectric material discovery and the mechanism investigation.Because of the various ceramics systems,pseudo phase diagram was used to classify the dielectric materials based on the composition.In this review,the ceramics were firstly divided into ternary systems,and then brief description of the experimental probes and complementary theoretical methods that have been used to discern the intrinsic polarization mechanisms and the origin of intrinsic loss was mentioned.Finally,some perspectives on the future outlook for high-temperature MWDCs were offered based on the synthesis method,characterization techniques,and significant theory developments.

Countermeasures of China Auto Industry in Challenging ITS Development

China automotive industry, as a sector di-rectly related with ITS, has been watching at-tentively the development and progress of ITS in Europe, America and Japan. Great importance attached to ITS, which integrates many modern hi-techs in one, will not only promote the mar-

中国城镇化空间主体——城市群发展格局与挑战

China’s urban agglomerations have gradually become new world economic centers and strategic regions under the initiatives of"The Belt and Road."Various researchers have long been interested in the issues encountered during the development of urban agglomerations.However,systematic research analyzing issues in the development of China’s urban agglomeration are relatively few.On the basis of a brief introduction to the concept of urban agglomeration and the status of current development in China,this paper analyzes current issues in China’s urban agglomerations from the perspectives of spatial attribution,function,resources,and environmental utilization as well as new patterns in urban agglomeration,which reaches the following conclusions:conficts exist between spatial identifcation and layouts in urban agglomerations;issues such as,unsound internally functioning systems,improper land utilization,and stressful resource and environmental pressures still prevail in certain urban agglomerations;in addition,the number and layouts of newly constructed areas in urban agglomerations are controversial because some new areas are eager to develop new cities but have neglected their transitions from and interactions with older districts,thus wasting resources unnecessarily.This paper also proposes certain suggestions regarding the problems mentioned above.In short,these fndings will elucidate a fresh perspective and ideas for researchers studying urban agglomeration and offer references related to policy making concerning China’s urban agglomerations in the future.
