With the development of intelligent technology, intelligent products start to come into people's sight. Wider thoughts are provided to enhance the efficiency of utilization of water resources in urban families because of the intelligent technology. Based on literature research, we regard the technology of water grading and saving as starting point and technical support. According to analysis of intelligent...
The design and development of an automatic identity management system for the retrieval and matching of tattoo images is considered to be very important in the advancement of the investigative capabilities of forensics as well as law enforcement agencies. Conventional tattoo-based retrieval techniques are keyword-based, where content and body location meta-data are combined in an indistinguishable...
Surveillance systems are very important for law enforcement and military applications. Capturing a biometric modality at a distance and under difficult conditions is a very challenging process. While face or gait can be used to identify an individual in such application, tattoos can also help in the identification process whenever available. Tattoos are considered a soft biometric and in some scenarios...
Computational methods derived from digital signal processing are playing a significant role in the security and copyrights of audio, video, and visual arts. In light of the quantum computing, the corresponding algorithms are becoming a new research direction in today's high-technology world. The nature of quantum computer guarantees the security of quantum data, so a safe and effective quantum watermarking...
The homogeneous nanocomposites of 1-pyrenebutyric acid modified nitrogen-doped carbon nanotubes (PBA/NCNTs) are synthesized for the immobilization of enzymes and glucose biosensing. Through the aqueous carbodiimide coupling chemistry, glucose oxidase (GOD) is covalently immobilized on the surface of the as-prepared PBA/NCNTs with high enzyme loading (1.986 ${\rm nmol}\cdot{\rm cm}^{-2}$ ). Fast direct...
Taking a super high-rise building as the engineering background, a wind resistant design method of high-rise buildings installed with viscoelastic dampers (VED) is presented in this paper. The mechanical model of VED system and the structure is established through the following steps. Firstly, the typical impulsive wind load is obtained by the impulsive wind simulation program developed by the author...
Recently, stampede accident in crowd-gathered place has become a hot topic in the research of public security. As a typical crowd-gathered place, the large business district is one of the most crowd places in the city. This paper studied the risk early-warning method of passenger flow in business district from four aspects: regional density, flow rate of the section, bidirectional flow ratio of the...
Innovation is a complicated process interacted by many factors such as knowledge, economy and society. Only by innovation synergy of market, technology and management, comprehensive profit which is higher than those done by one-sided innovation can be achieved. This paper gained conclusion that 1+1>2 synergy effect can't be realized by single innovation but innovation synergy. Based on the explanations...
