This research concerns the topic of Land Use and Transport Interaction (LUTI) models. In particular, the patterns between residential households’ location and mobility choices are analyzed and simulated. The attributes that influence household residential location choices belong to four categories: socioeconomic and mobility attributes of households and/or of their components; land use; real-estate market; transport system. The paper presents the results of a pilot study on households’ location and mobility patterns in the metropolitan area of Reggio Calabria (Southern Italy). The pilot study is divided into two stages. In the first stage, a survey allowed to collect information and identify existing patterns about residential and mobility choices of a sample of households. In the second stage, a residential location model is proposed and some preliminary calibrations are presented in a prototypal way. The pilot study could be extended and improved in terms of spatial extension and sample dimension in order to allow a complete specification-calibration-validation process of the model. The model development can support the land use-transport planning process in the Metropolitan City of Reggio Calabria.

This paper analyzes the land use and land cover change (LUCC) of Wuliangsu Lake by interpreting Landsat5 TM images of 1987, 2000 and 2010. In the first stage (1987-2000), the area of mobile sandy land increased significantly, which signed that the environment of Wuliangsu Lake got worse. On the contrary, in the second stage (2000-2010), over 50% of mobile sandy land transformed into fixed sandy land. In addition, grassland gained a large percent from fixed sandy land and swamp. All of these changes signed that the environment of Wuliangsu Lake got better. In the two stages, the area of residential area and farmland increased obviously, large amount of grassland, swamp and fixed sandy land were converted into farmland, so we can predict that the main reason for land use changes in Wuliangsu Lake is agricultural development.

The objective of this study is to propose, implement, and test a framework of assigning relevant Library of Congress (LC) subject headings to tweet messages. In this study, the task of assigning LC headings is considered an automatic classification task that identifies relevant LC subject headings for given tweets. The classification task is conducted in two stages. In the first stage, tweets are clustered so that similar tweets are grouped together. In the second stage, the degree of similarity between a cluster of tweets and LC subject headings is measured by a popular similarity metric, Jaccard Coefficient (JC). In this pilot study, five selected tweet clusters and nine LC subject headings were carefully chosen and used. This pilot study demonstrates a positive result forthe proposed approach of identifying subject headings for tweets. In three cluster cases out of the five, JC selected the most relevant headings as the largest degrees of similarity. For the other two cases, JC was not successful in ranking the most relevant within the top three headings. In the next step, a more sophisticated clustering method will be explored and applied. Also, all possible LC subject headings will be employed to identify LC subjects for tweets in the next steps of this study.

This chapter describes the manner by which the ANES converted the insights of many people into strong and innovative questionnaires. This description is broken into two stages to reflect the nature of the decision-making processes. The first stage began in 2006, two years before the general election of 2008. The chapter describes how a large set of new questions were evaluated and which questions were to be included in the 2006 Pilot Study. The second stage began about six weeks after the pilot study, when the data was released to the public. This period started at the end of 2006 and continued into the early months of 2008. The chapter looks at how the Pilot Study Reports from the period were evaluated and how these evaluations affected choices of which questions would appear on one or more of the 2008 studies.

Abstract. The development of semidistributed hydrological models that reflect the dominant processes controlling streamflow spatial variability is a challenging task. This study addresses this problem by investigating the case of the Thur catchment (Switzerland), an alpine and pre–alpine catchment that, while having a moderate (1702 km2) extension, presents a large spatial variability in terms of climate, landscape, and streamflow (measured at 10 subcatchments). The methodology for model development consists of a two–stages approach. In a first stage, we use correlation and regression analysis to identify the main influencing factors on the spatial variability of streamflow signatures. Results of this analysis show that precipitation (rainfall or snow) controls signatures of seasonality and water balance, while landscape characteristics (especially geology) control signatures of hydrograph shape (e.g. baseflow index and flashiness index). In a second stage, we use the results of the previous analysis to develop a semidistributed hydrological model that is consistent with the data. Model experiments confirm that only hydrological models that account for the heterogeneity of precipitation and geology produce hydrographs that have signatures similar to the observed ones. These models provide consistent results in space–time validation, which is promising for prediction in ungauged conditions. The presented methodology can be transferred to other case studies, since the data used in this work (meteorological variables, streamflow, morphology and geology maps) is available in many regions around the globe.

Belief systems as discussed by Harvey and colleagues provide a summary description of individual differences across a variety of psychological characteristics in combination with people's assumptions as to how the world operates. Here we provide a brief report as to how individuals' belief systems related to their attitudes toward workplace issues which were defined in the course of the study. The data on which these conclusions were based were collected in two stages of a pilot study. The second stage used a refinement of the inventory which measured attitudes toward the workplace in the first stage, both stages used the same inventory for measuring belief systems. People with different belief systems had divergent concerns in the workplace. The most prominent finding was that “cynics” tend to express negative attitudes toward the same issues which “extrapersonalists” (who are more likely to be managers) tend to favor.

B-lymphocytes normally synthesize small amounts of immunoglobulin, some of which is incorporated into the cell membrane where it serves as receptor of antigen. These cells, on contact with specific antigen, proliferate and differentiate to plasma cells which synthesize and secrete large quantities of immunoglobulin. The two stages of differentiation of this cell line (generation of B-lymphocytes and antigen-driven maturation to plasma cells) are clearly separable during ontogeny and in some immune deficiency diseases. The present report describes morphologic aberrations of B-lymphocytes in two diseases in which second stage differentiation is defective.

Ch Selection

In Wireless Sensor Networks (WSN) the energy of Sensor nodes is not certainly sufficient. In order to optimize the endurance of WSN, it is essential to minimize the utilization of energy. Head of group or Cluster Head (CH) is an eminent method to develop the endurance of WSN that aggregates the WSN with higher energy. CH for intra-cluster and inter-cluster communication becomes dependent. For complete, in WSN, the Energy level of CH extends its life of cluster. While evolving cluster algorithms, the complicated job is to identify the energy utilization amount of heterogeneous WSNs. Based on Chaotic Firefly Algorithm CH (CFACH) selection, the formulated work is named “Novel Distributed Entropy Energy-Efficient Clustering Algorithm”, in short, DEEEC for HWSNs. The formulated DEEEC Algorithm, which is a CH, has two main stages. In the first stage, the identification of temporary CHs along with its entropy value is found using the correlative measure of residual and original energy. Along with this, in the clustering algorithm, the rotating epoch and its entropy value must be predicted automatically by its sensor nodes. In the second stage, if any member in the cluster having larger residual energy, shall modify the temporary CHs in the direction of the deciding set. The target of the nodes with large energy has the probability to be CHs which is determined by the above two stages meant for CH selection. The MATLAB is required to simulate the DEEEC Algorithm. The simulated results of the formulated DEEEC Algorithm produce good results with respect to the energy and increased lifetime when it is correlated with the current traditional clustering protocols being used in the Heterogeneous WSNs.

Outburst Hazard

Abstract The Author endeavored to consult some of the Polish experts who deal with assessing and preventing outburst hazards as to their knowledge and experience. On the basis of this knowledge, an expert system, based on fuzzy logic, was created. The system allows automatic assessment of outburst hazard. The work was completed in two stages. The first stage involved researching relevant sources and rules concerning outburst hazard, and, subsequently, determining a number of parameters measured or observed in the mining industry that are potentially connected with the outburst phenomenon and can be useful when estimating outburst hazard. Then, the Author contacted selected experts who are actively involved in preventing outburst hazard, both in the industry and science field. The experts were anonymously surveyed, which made it possible to select the parameters which are the most essential in assessing outburst hazard. The second stage involved gaining knowledge from the experts by means of a questionnaire-interview. Subjective opinions on estimating outburst hazard on the basis of the parameters selected during the first stage were then systematized using the structures typical of the expert system based on fuzzy logic.
