For polymer electrolyte based devices, it highlights that a strategic simple switch from proton exchange membranes(PEMs) to hydroxide exchange membranes(HEMs) may lead to a new-generation of affordable electrochemical energy devices including fuel cells, electrolyzers, and solar hydrogen generators. For lithium-ion batteries, a series of advancements in design and chemistry are required for electric vehicle and energy storage applications. Manufacturing process development and optimization of the LiF eP O_4/C cathode materials and several emerging novel anode materials are also discussed using the authors' work as examples.Design and manufacturing process of lithium-ion battery electrodes are introduced in detail, and modeling and optimization of large-scale lithium-ion batteries are also presented. Electrochemical energy materials and device innovations can be further prompted by better understanding of the fundamental transport phenomena involved in unit operations.展开更多

An innovation which is comparable, if only slightly less significant, was the transition from using 2D systems to the 3D structural model design. The article outlines the advantages of using BIM in the preparatory stages of a construction project. It also presents benefits which relate to the employment of the BIM system in cost estimation process. The article describes the Zuzia BIM system which uses the BIM model, as this system has just been created in Poland for the purpose of construction cost estimation. The preparation of the bill of quantities is automated in this system and this has been achieved on the basis of data directly obtained from virtual models of buildings, which were carried out thanks to the collaboration of various design sectors. The article authors, using their own experience, present difficulties which can be encountered by cost estimators in Poland when calculating the value of a building with the help of the BIM concept. The article shows the design errors that prevent or hinder takeoff automatic calculation based on BIM model. Design errors shown in the article are for example reinforcement bars have been defined by a designer as elements hollow in the middle or as one element for the whole building, one type of elements assigned as few different or incorrect defining of elements in relation to the type of works.展开更多

The ...This article provides an overview of an eleven step solid waste analysis and minimization process that is based on the six sigma approach to problem solving that may be applied at a wide variety of organizations. The six sigma approach provides a holistic process that focuses on minimizing defects, in this case, eliminating waste disposed at landfills. As many organizations are moving towards ＂zero landfill＂ facilities, such a process is needed to aid in achieving these goals. The eleven step processes provides details on establishing goals, creating process flowcharts, conducting waste sorts, data collection, establishing baseline data, identifying improvement opportunities, cost justification, executing improvement plans and validating results. The article also includes a case study that applies that eleven step process. The goal of the article is to provide the audience with a structured process to evaluate and minimize solid waste generation based on cost justified improvement opportunities.展开更多

As technology has evolved into various web fields, metaphors have become even more useful and at the same time more sophisticated. A current-generation site not only has an overall theme for the site, but the organization of the information and the navigational scheme is based on a metaphor of the theme, called a Web Metaphor. A web metaphor is a design element that helps the user to leverage their existing experience in the abstract environment of the web. In this study, an approach to a thinking process model for web design is proposed through the concept of metaphors, and a theoretical analysis based on creative thinking for solving design problems is studied. This study aims to provide a glimpse into the world of metaphors and how they can be used in user interface design, to analyze selected examples, and to introduce a model web design process. As the study of the essence of creative thinking in web design is ongoing, diverse possibilities for solving problems in web design can be found through the theoretical modeling of thinking in web design. This study will also explore strategic and effective web design by establishing a mental model for web designers based on the study of metaphors that will inspire the thinking of designers.展开更多

The aims of innovations are to decrease required power of construction （in particular, piling） equipment and, correspondingly, to improve environmental situation at the construction site. Another achieved goal is providing long tubular piles installation in hard soils conditions without application of very heavy and powerful driving machines. Worked out solutions are based on two approaches. One of them provides separate loading of driving force on pile＇s shaft and pile＇s tip concentrating the whole driving force on one of the mentioned parts of the pile. Another approach is focused on prevention of soil plug formation inside of the tubular pile tip facilitating the pile installation process. Also improved anchorage system for sheet piling seafront walls is presented and discussed. All considered innovations are patented and can be used in wide range of marine, offshore, coastal and harbor structures.展开更多

Combined with successful cases, this study analyzed and showed that one should not only deal with the relationship between the original architectural style and construction of modem cities in the process of renovation design of the old industrial building space. More attention should also be paid to create new space to meet the functional requirements of the modem features, and then complete substantial renovation of old industrial building space through the innovative design. In the use of aesthetic innovative design for the renovation of the old industrial building space, people must respect the space of old industrial buildings as the prerequisite of the renovation design. It is needed to expound the local space reconstruction methods and design principles respectively on the basis of respect. And then one should grasp the whole space and make the structured design and reasonable use according to the new space functional requirements of different functional areas. This paper attempted to learn from environmental art study on the renovation of old industrial buildings space and in terms of innovative design. The authors explored the innovative thinking on the renovation design of old industrial building space through the analysis of the reality.展开更多
