Background dominant colors extraction method based on color image quick fuzzy c-means clustering algorithm

A quick and accurate extraction of dominant colors of background images is the basis of adaptive camouflage design. This paper proposes a Color Image Quick Fuzzy C-Means (CIQFCM) clustering algorithm based on clustering spatial mapping. First, the clustering sample space was mapped from the image pixels to the quantized color space, and several methods were adopted to compress the amount of clustering samples. Then, an improved pedigree clustering algorithm was applied to obtain the initial class centers. Finally, CIQFCM clustering algorithm was used for quick extraction of dominant colors of background image. After theoretical analysis of the effect and efficiency of the CIQFCM algorithm, several experiments were carried out to discuss the selection of proper quantization intervals and to verify the effect and efficiency of the CIQFCM algorithm. The results indicated that the value of quantization intervals should be set to 4, and the proposed algorithm could improve the clustering efficiency while maintaining the clustering effect. In addition, as the image size increased from 128 × 128 to 1024 × 1024, the efficiency improvement of CIQFCM algorithm was increased from 6.44 times to 36.42 times, which demonstrated the significant advantage of CIQFCM algorithm in dominant colors extraction of large-size images.     

Dynamic impact protective body armour: A comprehensive appraisal on panel engineering design and its prospective materials

Personal body armour is one of the most important pieces of equipment to protect human beings from various critical and fatal injuries. In today’s modern world, various organizations including law enforcement and security service have made it mandatory for their personnel to wear personal protection system while on field duty. However, the systems should comprise an improved ballistic performance, light-weighted, flexible as well as comfortable panel not only to be accepted with a wider range but also for effective performances of the consumer. Generally, the overall performances of the protective body armour could be affected by various parameters including armour design techniques, type of materials used and finishing of the panels. The current paper aims to critically review state-of-art for armour panel design techniques and the different perspective body armour materials. The paper starts by discussing the different body armour and its category. Later, the different states of technology for armour panel design (mostly for women), its problems and the possible solutions will be cited. Later, the commonly used different polymeric fibrous and the future possible advanced materials including carbon nanotube (CNT), Graphene CNT and shear thickening fluids (STFs) treated materials for developing the reinforced body armour panel will be discussed. The authors believe that this paper will enlighten useful guidelines and procedures about the different panel design techniques and current and promising future materials for researchers, designers, engineers and manufacturers working on the impact resistance body armour field.     

关于公共消防安全管理学科建设和专业设置的思考

公共安全问题,已经成为影响我国经济发展和社会稳定的主要问题之一,并已引起社会的广泛关注。公共安全管理正在作为一个学科和人才培养专业发展起来。消防安全是公共安全的主要内容之一,以消除火灾危害为主要目的的公共消防安全管理,既有公共安全管理的共性问题,也有自己独特的问题。公共消防安全管理与现有的消防指挥学科、消防工程学科有较大的区别,是后两者不能取代和涵盖的。因此,完善公共消防安全管理学科建设,设立公共消防安全管理专业非常必要。本文分析了我国消防学历教育中专业设置和课程设置所存在的问题,提出设置公共消防安全管理专业的必要性和重要性,并对公共消防安全管理学科建设提出了建设性意见。

新中国道德建设的基本经验及发展走向

新中国道德建设的基本经验主要是：形成了社会主义道德体系,坚持社会主义核心价值体系主导地位;明确了“相适应”、“相协调”、“相承接”三者统一的目标任务,坚定中国特色社会主义方向;坚持了先进性与广泛性相结合的实践要求,发挥先进典型示范引导作用,等。在新的历史时期,我们要力戒道德建设的“无我化”、“空洞化”和“泛政治化”,抵制“非道德主义”和“道德相对主义”的泛滥与风行。新中国道德建设的发展走向是：要在社会主义核心价值体系中,大力践行社会主义荣辱观;在“四观”中凸显道德观教育;在“四真”上下工夫塑造道德主体。
