Flexibility of MIP Technology

The flexibility of MIP technology to meet market demand is mainly introduced in this study. Their commercial application and technical principle are analyzed too. The MIP technology with wide feed adaptability can form a good combination with other technologies. The MIP technology has been applied extensively in China. Based on this platform, the CGP, MIP-LTG and MIP-DCR technologies have been developed, which can further improve the flexibility of MIP technology. Based on its novel reaction control technique with a sole sequential two-zone riser, the MIP users can easily switch to different operating modes between producing either more clean gasoline and propylene or diesel through changing the catalysts and varying the operating conditions. That offers MIP users with enough production flexibility and a rational production arrangement to meet the market demand. The MIP-DCR technology with less dry gas and coke yields can provide a more flexible operating mode since the catalysts to oil ratio has become an independent variable.

This paper focuses on the changing process of global competition model based on the analysis of production model and its tendency of development, especially analyses the positive effect of mass customization. The paper introduces the concept of market turbulence to decide the occasion of transformation to mass customization for industries/enterprises. Several transformation roadmaps to mass customization and competitive models and strategies are established.

Modified origin-based algorithm for traffic equilibrium assignment problems

Key tactics of origin-based user equilibrium (OUE) algorithm was studied,which involved the algorithm procedure and several implementation issues.To speed up the convergence,update policies of flows,costs and bushes were proposed.The methods of step-size searching and bush construction are proved to be practical.The modified OUE algorithm procedure was also optimized to take the advantage of multi-thread process.Convergence performances were compared with those of other algorithms by different sizes of urban transportation networks.The result shows this modified OUE algorithm is more efficient and consumes less time to achieve the reasonable relative gap in practical applications.

Participation of Users in Traditional and Modern Turkish Settlements

When the development level of a city is determined, its residents＇ level of participation and support to social organizations, especially the voluntarily participation to civil organizations, are taken into account, as well as, their level of utilization from city services. It is beneficial to organize civil groups who are sensitive to urban and environmental issues. In traditional Turkish settlements, it can be talked about the existence of such an organization as a natural process in social organizations including moral and humanistic values. The feeling of belonging had raised the environmental quality both physically and socially. Respect to the nature and human was the main principle of these settlements. Such organizations has displaced with the written rules and official or civil organizations in modern urban settlements. In these organizations, participation of the users to urban planning decisions is not directly, but indirectly. As people who live in modern settlements do not participate to the planning and building process, they have not felt themselves belong to the place. The environmental quality and respect to the nature and human have been lessened in these modern settlements. This study focuses on the participation of users on planning and building housing environments in traditional and modern Turkish settlements and the comparison of them with their positive and negative results with the examples given.

Modelling the User

The relatively high percentage of people with disabilities in Europe combined with the facts of ageing population, strong relation of impairment to age, and as State of the Art shows, dissatisfaction or even unawareness of people with disabilities of available assistive technology are revealing the necessity to incorporate a user-centric approach that beyond 2nd generation practices will achieve to provide embedded and built-in accessibility solutions, as well as toolkits for developers, for ＂engraving＂ accessibility in existing and emerging mass-market ICT-based products, aiming to make accessibility open, plug and play, personalised and configurable, realistic and applicable in various contexts, keeping always the user in the loop. The AEGIS （Accessibility Everywhere： Groundwork, Infrastructure, Standards） IP （Integrated Project） of the 7th European Framework Programme seeks to determine whether 3rd generation access techniques will provide a more accessible, more exploitable and deeply embeddable approach in mainstream ICT （information and communication technologies）. This paper presents the holistic UCD （user-centered design） implementation plan, upon which AEGIS has been based in order to achieve its targets, starting from modelling its target users, in the most efficient way possible.

Space-Use Analysis in the Design of Neighborhood Walking Paths

SUA （space-use analysis） is about techniques that objectively describe environments and relate this description to specific problems of use. The purpose of this paper is to explore a space-use analytical tool--POE （post-occupation evaluation）--regarding a neighborhood accessibility condition. Based on a site-specific approach, the main research question is focused on how far neighborhood walking paths are compatible with different user needs, guaranteeing their safety and autonomy, as well as easiness of perception and use, thus providing access to local services and resources they need for participation in the day-to-day activities of community life. This paper is organized in three parts： The first one introduces the main concepts and explains how to ensure it in a practical application in urban design; The second part presents the practical approach, referring to the used methodology, the specific case-study and reached results; The third one establishes correlations between the two approaches and discusses the main findings.

Improvement of User's Accuracy Through Classification of Principal Component Images and Stacked Temporal Images

The classification accuracy of the various categories on the classified remotely sensed images are usually evaluated by two different measures of accuracy, namely, producer＇s accuracy （PA） and user＇s accuracy （UA）. The PA of a category indicates to what extent the reference pixels of the category are correctly classified, whereas the UA of a category represents to what extent the other categories are less misclassified into the category in question. Therefore, the UA of the various categories determines the reliability of their interpretation on the classified image and is more important to the analyst than the PA. The present investigation has been performed in order to determine if there occurs improvement in the UA of the various categories on the classified image of the principal components of the original bands and on the classified image of the stacked image of two different years. We performed the analyses using the IRS LISS Ⅲ images of two different years, i.e., 1996 and 2009, that represent the different magnitude of urbanization and the stacked image of these two years pertaining to Ranchi area, Jharkhand, India, with a view to assessing the impacts of urbanization on the UA of the different categories. The results of the investigation demonstrated that there occurs significant improvement in the UA of the impervious categories in the classified image of the stacked image, which is attributable to the aggregation of the spectral information from twice the number of bands from two different years. On the other hand, the classified image of the principal components did not show any improvement in the UA as compared to the original images.

China＇s Housing Market Imbalance from 2003 to 2016： An Analysis Based on the User Cost Approach

During 2003-2016, China experienced an unprecedented housing market imbalance. The present paper applies the user cost approach to conduct a systematic analysis of this important phenomenon, examines the policy factors behind the persistent housing market imbalance, and explores policy options to correct the housing market imbalance. We found that during most of 2003-2016, the user cost was significantly lower than 2 percent, caused by high income growth, rapid credit expansion and low interest rates, which led to the persistent housing market imbalance. Therefore, the government should control bank credit and introduce property taxes during the possession of houses.
