Parametric 3D modeling of young women's lower bodies based on shape classification

Three-dimensional (3D) human body modeling is an important research direction in the field of clothing virtual design. On the basis of 3D human body scanning, this paper studied a method to build a 3D parametric lower body model according to body classification. The research includes three main parts. (1) Anthropometry and body shape classification. We randomly selected 333 young women ages 18–25 years old in Northeast China as the experimental sample. Then we divided the lower body shape into three categories using principal component analysis and K-means clustering. (2) Determination of feature cross sections and points, and reconstruction of feature curves. According to the average values of each body type, we obtained the mean reference body by Euclidean distance method. We determined feature cross sections and points, and extracted the 3D coordinates of the feature points of the mean reference body to reconstruct the feature curves. (3) The surface lofting and establishment of parametric 3D lower body model. According to the shape characteristics of the lower body, we constructed the guiding lines for the crotch and lower limbs, and established parametric lower body models for three body types.Relevance to industry3D human modeling is an important part of garment industry digitization. This research provides an effective way to construct a parametric 3D lower body model. The method offers a reference for the parametric virtual human modeling and virtual fitting of trousers.

东北地区冬季气温对海温异常响应的研究

利用HadISST OI海温和中国东北地区92站逐日气温资料,使用广义平衡反馈分析方法(GEFA)结合EOF分析方法(GEFA-EOF)研究了近50 a中国东北地区冬季气温对海表温度异常(SSTA)的响应.结果表明:对于热带和北半球中纬度5个海盆来说,东北地区冬季气温异常与同期热带大西洋和北大西洋海温异常有密切关系,与其他海盆关系不显著;热带大西洋的"正—负—正"三极型模态(TA3)以及北大西洋纬向上"正—负—正"三极型模态(NA3)分别对东北地区冬季气温的异常偏低和偏高有显著的强迫作用,且对北部地区的强迫作用大于南部地区.热带大西洋和北大西洋对东北地区冬季气温异常影响的可能途径为:热带大西洋TA3模态通过在北半球激发的"正—负—正"的遥相关波列,致使东亚大槽移至贝加尔湖地区,有利于极地冷空气南下至东北地区,导致该地区的冷冬;北大西洋的"正—负—正"三极型模态(NA3)直接响应使得东亚大槽减弱消失,极地冷空气南下受阻,导致该地区冬季气温异常偏高.     

中国东北地区的盐渍土资源

通过长期区域土壤考察,我国东北地区盐渍土资源的面积约为7 66×106hm2,其中松嫩平原的盐渍土面积占39 3%,西辽河沙丘平原占30 3%,辽河冲积平原占12 8%,呼伦贝尔盟高平原占9 3%,滨海平原占7 9%,三江平原仅占0 4%而已,20世纪80年代不同辖区所获的土壤普查结果与之相接近。在上述的盐渍土资源面积中,其潜在盐渍土的面积约占34%。在开发利用方面,盐渍土的耕地面积已由20世纪50年代的占其总耕地面积的21 4%,增加为80年代的37 8%,呈显著增长之势。水田灌区土壤普遍脱盐,作物高产稳产,已属新型的人工生态系统。在盐渍土旱作区,农作物亦已普遍持续增产,惟局部土壤的脱盐状况尚不甚稳定,其西部地区的盐渍化面积呈明显蔓延之势,主要原因在于大面积天然草场的土壤盐渍度加剧,生产力普遍下降。上述中国东北地区盐渍土资源的面积约占全国盐渍土面积的7.9%,战略地位重要,其实现农业可持续发展的开发利用任务仍然十分艰巨。     

Methodological approach to the study of the electro-hydrogen system in Northeast Asia

The article proposes a methodological approach to the development of the tools for studying the international electro-hydrogen system creation in Northeast Asia. The term "hydrogen carrier" was introduced and its definition was given. The resource, economic and technological prerequisites for the development of the unified regional infrastructure to produce, transfer, transform and utilise both electricity and "hydrogen carriers" for consumers of energy services are considered.The author points out the need for a comprehensive consideration of technological, economic, social and political factors when developing such a complex technical system, which affects the diverse actors' interests. In order to create mutual understanding and balance the stakeholders’ interests, the tool to evaluate the efficiency of such a system is necessary. The use of mathematical models is becoming one of the most vital and widespread techniques employed for this purpose. Thereby, the article deals with the structure and the development stages of a regional electro-hydrogen model for Northeast Asia.The review of models that address the issues of hydrogen technologies and renewable energy integration into energy supply systems is given. The main types of models used to describe such technical and economic systems are identified and it is concluded that the development of a two-level modelling system is necessary. The production and transport models at the upper (international) level should be the core of the proposed models system. At the lower level (the "green hydrogen carriers" production), the models of optimal resource management are required to determine the composition and parameters of the technological equipment.Step-by-step development of the modelling system is proposed. The first stage is the simplest scenario where only solar and wind energy is considered as an energy source. At this stage, it is possible to weed out inefficient technologies and identify targeted technologies and mechanisms for multilateral regional cooperation. The second stage should balance the interests of the actors and stakeholders. Here, the traditional renewable energy (biomass, hydro and pumped storage) along with carbon (thermal) and nuclear power generation, as well as other ("carbon") hydrogen technologies will become available for consideration. The final, third stage of the research tools development, will require separate accounting of "green" and "carbon" energy to consider certification mechanisms and energy pricing when building the international hydrogen system in Northeast Asia.In conclusion, the structure of the first stage production and transport model is described. This model will allow estimating the comparative effectiveness of different electric and hydrogen technologies to deliver green energy to consumers in the Northeast Asian economies.
