Environmental effects are not considered sufficiently in product design. Reliability problems caused by environmental effects are very prominent. This paper proposes a method to apply ontology approach in product design. During product reliability design and analysis, environmental effects knowledge reusing is achieved. First, the relationship of environmental effects and product reliability is analyzed. Then environmental effects ontology to describe environmental effects domain knowledge is designed. Related concepts of environmental effects are formally defined by using the ontology approach. This model can be applied to arrange environmental effects knowledge in different environments. Finally, rubber seals used in the subhumid acid rain environment are taken as an example to illustrate ontological model application on reliability design and analysis.

Through introducing the design axioms in axiomatic design, the thesis elaborated the relationship between axiomatic design and reliability design of product, then analyzed the effects of product reliability caused by coupled design, and explained the necessity that avoided coupled design and the significance that kept the product function independent during product design.

El barrio Ituzaingó Anexo está ubicado en la periferia sureste de la ciudad de Córdoba. Hace dieciséis años, la lucha de un grupo de madres visibilizó el conflicto ambiental que aún viven. Tal hecho, se hizo evidente al identificar enfermedades y muertes causadas por los efectos ambientales de los agrotóxicos en la producción de soja transgénica. En este trabajo, nos preguntamos de qué manera quienes deciden sobre la ciudad también son responsables de los daños ambientales producidos en este sector de la sociedad, a partir de comprender la relación del barrio con la configuración de la ciudad. Para esto, analizamos el surgimiento de Ituzaingó Anexo como barrio obrero en la expansión industrial de la ciudad y posteriormente el inicio del modelo productivo de agricultura extensiva. Haciendo énfasis en la incompatibilidad de usos habilitados por la zonificación en la planificación de la ciudad, y los efectos de segregación urbana y ambiental. The Ituzaingó Anexo neighborhood is located on the Córdoba’s city southeast periphery. Sixteen years ago, the struggle of a mother’s group made visible the environmental conflict that they still live through. This fact became evident when they identified diseases and deaths caused by the environmental effects of agrotoxics in the production of transgenic soybeans. In this work, we wonder how those who decide about the city are also responsible for the environmental damage produced in this sector of society, understanding the relationship of the neighborhood with the configuration of the city. In this way, we analyze the creation of Ituzaingó Anexo as a working class neighborhood in the industrial expansion of the city and later the beginning of the productive model of expansive agriculture. Emphasizing the incompa tibility of uses enabled by zoning in the planning of the city, and the effects of urban and environmental segregation.

This research is to develop the products that can communicate environmental information to the user. The study investigated design styles of eco-information and impact on user’s emotions which can be used as data for product design enhancing environmental perception and encouraging behavioural change. The research aimed to 1) study design styles of eco-information and impact on user’s emotions 2) analyse the relationship of design styles and impact on user’s emotions effective in promoting environmental behaviour change. Ten-second video clips of seven design styles were presented through a computer and a projector and perception evaluation forms were employed. The sample included 60 students from the Faculty of Architecture and Design, Rajamangala University of Technology Phra Nakhon, Bangkok, Thailand. The results showed that the most effective design style could encourage emotions in the aspects of interest, excitement and preference. This study found that using living creatures to encourage emotions was the most effective attribute. Additionally, giving detailed information through the use of texts and graphs could encourage effectiveness in promoting behavioural change towards energy and resource consumption.

The main essentials of power units and their accessories have not changed significantly over the last 40 years, and fuel feed pumps come into this category. The basic requirements are well established, but there has been a continual striving for improved performance and strenuous efforts to reduce costs in order to meet the vehicle manufacturers' demands. The author has endeavoured to indicate the trends in developments of the various types of fuel pumps, mechanical and electrical, with particular reference to application and performance for petrol and diesel equipment. The importance of correct installation is related to performance and reliability; design materials are discussed, particularly in relation to the influence of fuels and temperature and the need to meet the demands of modern high-output engines. Mention is made of the relationship of fuel feed systems to safety and evaporative emission control and the special requirements of fuel injection installations. The need for efficient fuel filtration is discussed and the application and design details of filters are outlined.

Quality Function Deployment (QFD), a set of concepts and tools often used in manufacturing engineering to link consumer needs with product design, can be used to improve academic advising systems and processes. QFD promotes a structured and logical examination of students' advising needs and a rigorous examination of the relationship of these needs to the design of advising systems, processes, methods, and tools. Because its conceptual base is radically different from the disciplines underpinning advising theory, QFD can offer advising leadership useful insights and avenues for advising improvement.

King's general systems model provides a useful way to organize and implement a curriculum in nursing. The model clarifies the relationship of individuals and families to communities by using concepts that define personal, interpersonal, and social systems. A model has been developed that uses concepts, axioms, skills, and values as the central components of the curriculum.

This paper uses modern products design style to analysis new peculiarities hiding in the new modern products, and combing the examples in life to analysis the different design logos that products design have in the new form. And it clears the future trends of products design in which foundation, we propose the Art sublimation of modern product design, it including the Traditional Art Extension in modern product design, the using of “Subconscious” ideal in the product design and the product “redesign”. At last it discusses the relationship of” Low-carbon” and the modern products design.

Faults are the commonly encountered large geological discontinuities in hard rock masses, many severe open pit slope failures are found to be closely associated with the faults presence nearby. Open-pit slope takes shape gradually as a rock unloading process accompanied by geostress redistribution, especially in a slope containing a fault. The finite difference code (UDEC) was employed as the analytical method in this paper and coulomb slip model was utilized to describe the properties of fault provided by UDEC. Parametric analysis has identified both the fault dips and fault locations relative to the open pit slope to be really critical for the open pit slope stability. The relationship of crest displacements, safety factor varying with these fault parameters was established. The distribution of plastic zone and displacement was graphically presented and the mechanisms such effects were discussed. These results offer a guideline in support design for an open-pit slope containing a fault.

Detection and responding to a player’s affect are important for serious games. A method for this purpose was tested within Chem-o-crypt, a game that teaches chemical equation balancing. The game automatically detects boredom, flow, and frustration using the Affdex SDK from Affectiva. The sensed affective state is then used to adapt the game play in an attempt to engage the player in the game. A randomized controlled experiment incorporating a Dynamic Bayesian Network that compared results from groups with the affect-sensitive states vs those without revealed that measuring affect and adapting the game improved learning for low domain-knowledge participants.
