    2005-04-01

    Urban squares are important components of cities, and the acoustic environment is important for their usability. While models and formulae for predicting the sound field in urban squares are important for their soundscape design and improvement, acoustic animation tools would be of great importance for designers as well as for public participation process, given that below a certain sound level, the soundscape evaluation depends mainly on the type of sounds rather than the loudness. This paper first briefly introduces acoustic simulation models developed for urban squares, as well as empirical formulae derived from a series of simulation. It then presents an acoustic animation tool currently being developed. In urban squares there are multiple dynamic sound sources, so that the computation time becomes a main concern. Nevertheless, the requirements for acoustic animation in urban squares are relatively low compared to auditoria. As a result, it is important to simplify the simulation process and algorithms. Based on a series of subjective tests in a virtual reality environment with various simulation parameters, a fast simulation method with acceptable accuracy has been explored.

    Facing climate change and global warming, outdoor climatic environment is an important consideration factor for planners and policy makers because improving it can greatly contribute to achieve citizen's thermal comfort and create a better urban living quality for adaptation. Thus, the climatic information must be assessed systematically and applied strategically into the planning process. This paper presents a tool named Urban Climate Map System (UCMS) that has proven capable of helping compact cities to incorporate climate effects in planning processes in a systematic way. UCMS is developed and presented in a Geographic Information System (GIS) platform in which the lessons learned and experience gained from interdisciplinary studies can be included. The methodology of UCMS of compact cities, the construction procedure, and the basic input factors - including the natural climate resources and planning data - are described. Some literatures that shed light on the applicability of UMCS are reported. The Municipality of Arnhem is one of Dutch compact urban areas and still under fast urban development and urban renewal. There is an urgent need for local planners and policy makers to protect local climate and open landscape resources and make climate change adaptation in urban construction. Thus, Arnhem is chosen to carry out a case study of UCMS. Although it is the first work of Urban Climatic Mapping in The Netherlands, it serves as a useful climatic information platform to local planners and policy makers for their daily on-going works. We attempt to use a quick method to collect available climatic and planning data and create an information platform for planning use. It relies mostly on literature and theoretical understanding that has been well practiced elsewhere. The effort here is to synergize the established understanding for a case at hand and demonstrate how useful guidance can still be made for planners and policy makers.

Anticipating on the effects of climate change, the research was guided by the question: Which urban design principles can be applied in specific Dutch neighbourhoods to respond to the effects of climate change, especially in terms of outdoor thermal comfort and water management?The three stages of the project are: A literature review of existing knowledge on climate adaptation and knowledge gapsResearch into the specific field of urban climatologyApplied research on the broader field of urban planningThe urban climate and adaptation measuresIn the evaluation of measures for climate robust urban areas it is important to gauge the extent of the effects of such measures. These effects are generally expressed in terms of air temperature. However, the comparison of results of measures from various studies is not a simple matter: there are significant differences in spatial, climatological and methodological variations adopted in these studies. Bringing results together from very specific studies may give an impression of the potential of certain measures. For example, most studies support the idea that greening has the highest effect on thermal comfort as it provides both shade and active cooling due to ‘evapotranspiration’1. Nevertheless, vegetation can also retain heat, as we can feel after sundown. Other measures that were investigated for their effects are water, urban morphology, materials and colour

    Full Text Available In research on perception of open urban space, psychological and structural aspects are important, as well as social use. Social use however is most important, because open urban space and its green surfaces satisfies needs of an urban population. The psychological aspect applies to direct experiencing and perception of space, while the structural aspect proves that public urban places are an important category in the urban structure. On the example of Bevk square, Nova Gorica, three types of analyses were carried out. With the structural analysis and evaluation, development and structure of the place were shown, its problems and qualities. The survey on public opinion utilised the method of cognitive mapping, enabled definition of the image of the square, as perceived by everyday users. With the method of time samples events on the square were observed, in different time slots and days of the week.

  4. Urban food consumption and associated water resources: The example of Dutch cities.

    Science.gov (United States)

    Vanham, D; Mak, T N; Gawlik, B M

    2016-09-15

    Full self-sufficiency in cities is a major concern. Cities import resources for food, water and energy security. They are however key to global sustainability, as they concentrate a rapidly increasing and urbanising population (or number of consumers). In this paper, we analysed the dependency of urban inhabitants on the resource water for food consumption, by means of Dutch cities. We found that in extremely urbanised municipalities like Amsterdam and Rotterdam, people eat more meat and cereals and less potatoes than in other Dutch municipalities. Their current water footprint (WF) related to food consumption is therefore higher (3245l/cap/day) than in strongly urbanised cities (3126l/cap/day). Dutch urban citizens who eat too many animal products, crop oils and sugar can reduce their WF (with 29 to 32%) by shifting to a healthier diet. Recommended less meat consumption has the largest impact on the total WF reduction. A shift to a pesco-vegetarian or vegetarian diet would require even less water resources, where the WF can be reduced by 36 to 39% and 40 to 42% respectively. Dutch cities such as Amsterdam have always scored very high in international sustainability rankings for cities, partly due to a long history in integrated (urban) water management in the Netherlands. We argue that such existing rankings only show a certain - undoubtedly very important - part of urban environmental sustainability. To communicate the full picture to citizens, stakeholders and policy makers, indicators on external resource usage need to be employed. The fact that external resource dependency can be altered through changing dietary behaviour should be communicated.

    Models are presented that describe Virginia urban area annual peak streamflow per square mile based on basin percent urban area and basin drainage area. Equations are provided to estimate Virginia urban peak flow per square mile of basin drainage area in each of the following annual exceedance probability categories: 0.995, 0.99, 0.95, 0.9, 0.8, 0.67, 0.5, 0.43, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 (recurrence intervals of 1.005, 1.01, 1.05, 1.11, 1.25, 1.49, 2.0, 2.3, 5, 10, 25, 50, 100, 200, and 500 years, respectively). Equations apply to Virginia drainage basins ranging in size from no less than 1.2 mi2 to no more than 2,400 mi2 containing at least 10 percent urban area, and not more than 96 percent urban area. A total of 115 Virginia drainage basins were analyzed. Actual-by-predicted plots and leverage plots for response variables and explanatory variables in each peak-flow annual exceedance probability category indicate robust model fits and significant explanatory power. Equations for 8 of 15 urban peak-flow response surface models yield R-square values greater than 0.8. Relations identified in statistical models, describing significant increases in urban peak stream discharges as basin urban area increases, affirm empirical relations reported in past studies of change in stream discharge, lag times, and physical streamflow processes, most notably those detailed for urban areas in northern Virginia.

  8. Discerning urban spiritualities: Tahrir Square, Occupy Wall Street and the idols of global market capitalism

    Directory of Open Access Journals (Sweden)

    Calvyn C. du Toit

    2015-03-01

    Full Text Available Discernment might be said to be a process of searching for meaning in the light of an (un articulated Absolute. This search takes place in the tension between the private and public spheres of life, mostly mitigated by a community. Intermediate communities, such as churches or social movements, construct symbolic spirituality systems for its adherers to search for meaning in the light of an (unarticulated Absolute. The urban events of Occupy Wall Street and Tahrir Square also step into the tension between the public and private spheres of life, creating a (temporary symbolic spirituality system for its adherers. These events were attempts to construct alternatives to the meta-narrative of global market capitalism. As events attempting to symbolise an urban spirituality, Tahrir Square and Occupy Wall Street dissipated rapidly, effecting rather little change at the heart of global market capitalism. This article theorises a possible reason for these urban spiritualities� dissipation, namely an overlap with global market capitalism�s idols of instant gratification and technology.Interdisciplinary Implications: Viewing Occupy Walls Street and Tahrir Square as symbolic systems of spirituality further strengthens theological urban discourse whilst adding weight to viewing mass movements as spiritualities attempting discernment.

  9. Climate adaptive urban planning and design with water in Dutch polders.

    Science.gov (United States)

    Schuetze, T; Chelleri, L

    2011-01-01

    The existing water management in Dutch polders is based on independent water systems for each polder. These are featuring artificial stabilized ground and surface water levels. As a result of the local climate the water levels in the polders are not continuously at a constant level. To maintain a stable water table in the polders, the surplus of relatively clean rainwater has to be pumped away during the cold seasons into canals or rivers, which are located on a higher level. During the summer relatively polluted water from these waterways is led into the polders to top up the declining water levels. This procedure leads to various problems regarding water quantity and water quality. The described existing system is not adaptable to climate change and includes the risk of flooding, particularly from torrential rain. Therefore it is crucial to develop, preferably self-sufficient, rainwater management systems in the polders. They should allow the fluctuation of the water levels inside the polders for seasonal storage and flood control. The described concept is adopted in the present water policy in the Netherlands as well as in research and recent urban development projects in Dutch polders.

    urban vitality are the co-presence of people as well as the social, cultural and economic activities in public spaces. The primary conditions are categorized as attractor-determinism, space-determinism and people-determinism. In regard to the spatial factors, the focus is on the spatial configuration of street networks, the composition of urban blocks and neighborhoods, as well as the value of details on small scales. The non-spatial factors primarily include the changing urban planning and governance approaches. The systems approach of planning and control, and the decentralization of decision-making powers are of particular importance to the topic. Various urban vitality evaluation criteria are derived, and then applied and tested in the comparative case studies.The Dutch new town Almere and the Chinese new town Tongzhou are both important new towns in their regions. They are selected based on their contrasting features as planned and market-driven, self-organized new towns, and the resultant differences in the level and character of their urban vitality. It is believed that their governments could gain inspiration from each other’s experiences for the future development of the towns. The key analytical approach of the case studies is to overlap multiple layers of top-down socio-spatial analyses with the actual space use from the bottom-up field investigations. The spatial analysis focuses on finding relations between the distribution of the planned and unplanned socioeconomic activities and the spatial configuration of different elements on different scales. Space syntax is adopted as one of the key analytical tools. The field study tasks include registering people’s movement of flows through static snapshots method, the mapping of self-organized small-businesses, activities and space appropriations, and conducting interviews and surveys of city officials, local people and shop owners.The results of the comparative case studies show that there is a strong

    2015-06-01

    Full Text Available Several studies all around the world were conducted on the phenomenon of the urban heat island, and referring to the results obtained, one of the most important factors that influence this phenomenon is the mineralization of the cities which means the reducing of evaporative urban surfaces, replacing vegetation and wetlands with concrete and asphalt. The use of vegetation and water can change the urban environment and improve comfort, thus reduce the heat island. The trees act as a mask to the sun, wind, and sound, and also as a source of humidity which reduces air temperature and surrounding surfaces. Water also acts as a buffer to noise; it is also a source of moisture and regulates temperature not to mention the psychological effect on humans. Our main objective in this paper is to determine the impact of vegetation, ponds and fountains on the urban microclimate in general and on the thermal comfort of people along the Independence square in the Algerian city of Sétif, which is a semi-arid climate, in particularly. In order to reach this objective, a comparative study between different scenarios has been done; the use of the Envi-met program enabled us to model the urban environment of the Independence Square and to study the possibility of improving the conditions of comfort by adding an amount of vegetation and water ponds. After studying the results obtained (temperature, relative humidity, PMV and PPD indicators, the efficiency of the additions we've made on the square was confirmed and this is what helped us to confirm our assumptions regarding the terms of comfort in the studied site, and in the end we are trying to develop recommendations and solutions which may contribute to improve the conditions for greater comfort in the Independence square. Keywords: microclimate, vegetation, water ponds, simulation, Envi-Met software, comfort.

    Urban expansion is a spatial phenomenon that reflects the increased level of importance of metropolises. The remotely sensed data and GIS have been widely used to study and analyze the process of urban expansions and their patterns. The capital of Libya (Tripoli) was selected to perform this study and to examine its urban growth patterns. Four satellite imageries of the study area in different dates (1984, 1996, 2002 and 2010) were used to conduct this research. The main goal of this work is identification and analyzes the urban sprawl of Tripoli metropolitan area. Urban expansion intensity index (UEII) and degree of freedom test were used to analyze and assess urban expansions in the area of study. The results show that Tripoli has sprawled urban expansion patterns; high urban expansion intensity index; and its urban development had high degree of freedom according to its urban expansion history during the time period (1984-2010). However, the novel proposed hypothesis used for zones division resulted in very good insight understanding of urban expansion direction and the effect of the distance from central business of district (CBD).

  17. The Influences of Actual and Perceived Familiarity on Environmental Preferences for the Design of a Proposed Urban Square

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available People gain actual familiarity through direct experience of environments, but environments we have never visited can still seem familiar. To date, few academic studies have investigated this phenomenon of perceived familiarity. This paper discusses the concept of perceived familiarity and environmental preference from the perspective of people who may be asked to make judgements of future urban designs as part of the planning process. A sample of local (n=102 and nonlocal (n=176 people were asked to rate images of two versions (existing environment and proposed redesign of an urban square on scales of preference and perceived familiarity. Results showed that the mean ratings for the proposed design were similar for both local and non-local samples. However, we found a clearly discernible difference in the way psychological antecedents are associated with environmental preference. For nonlocals, preference for the existing design is significantly associated with preference for the proposed design, but for local people this is not the case. In addition, for non-locals perceived familiarity of the proposed design is associated with perceived familiarity of the existing environment, but for the local sample this is not the case. Implications for public participation processes in urban design, as well as limitations and future lines of research, are discussed.

    Full Text Available This study examines the dominance of the D/H ratio as a design element for an enclosed urban square, long claimed by numerous urban designers. It claims that like the D/H ratio, other design elements significantly affect the perceptual quality of an enclosed square, but their impacts differ according to the context in which they are applied. The study reviews the literature pertaining to enclosures as an urban design strategy and design elements for an enclosed urban square. Then it presents a comparative analysis of the impact of the D/H ratio and other design elements such as the size of the square and the facade design using a visual assessment survey with computer-simulated images of urban squares. Results of the analysis support the argument that like the D/H ratio, the square size and its facade design have a considerable but distinctly different influence on users’ perceptions of urban squares.

    The water distribution system of one residential district in Tianjin is taken as an example to analyze the changes of water quality. Partial least squares (PLS) regression model, in which the turbidity and Fe are regarded as con-trol objectives, is used to establish the statistical model. The experimental results indicate that the PLS regression model has good predicted results of water quality compared with the monitored data. The percentages of absolute relative error (below 15%, 20%, 30%) are 44.4%, 66.7%, 100% (turbidity) and 33.3%, 44.4%, 77.8% (Fe) on the 4th sampling point; 77.8%, 88.9%, 88.9% (turbidity) and 44.4%, 55.6%, 66.7% (Fe) on the 5th sampling point.

    2017-01-01

    To better understand the influence of urban green infrastructure (UGI) on outdoor human thermal comfort, a survey and physical measurements were performed at the campus of the University of Groningen, The Netherlands, in spring and summer 2015. Three hundred eighty-nine respondents were interviewed in five different green spaces. We aimed to analyze people's thermal comfort perception and preference in outdoor urban green spaces, and to specify the combined effects between the thermal environmental and personal factors. The results imply that non-physical environmental and subjective factors (e.g., natural view, quiet environment, and emotional background) were more important in perceiving comfort than the actual thermal conditions. By applying a linear regression and probit analysis, the comfort temperature was found to be 22.2 °C and the preferred temperature was at a surprisingly high 35.7 °C. This can be explained by the observation that most respondents, who live in temperate regions, have a natural tendency to describe their preferred state as "warmer" even when feeling "warm" already. Using the Kruskal-Wallis H test, the four significant factors influencing thermal comfort were people's exposure time in green spaces, previous thermal environment and activity, and their thermal history. However, the effect of thermal history needs further investigation due to the unequal sample sizes of respondents from different climate regions. By providing evidence for the role of the objective and subjective factors on human thermal comfort, the relationship between UGI, microclimate, and thermal comfort can assist urban planning to make better use of green spaces for microclimate regulation.

    The Rocky Mountain Arsenal (RMA) was a United States chemical weapons manufacturing center located in the Colorado, Denver area. This presentation described the transformation of this highly contaminated site into a premier urban wildlife refuge. It included background information on the RMA and described the manufacturing and disposal history, including munition storage, liquid waste disposal and an overview of groundwater contamination. Soil remedies were summarized with particular reference to the timeline of the reclamation; wildlife-remedy/refuge interaction; innovative technologies such as hex pits and a dioxin study; and nuisance odour projects. The RMA was described as a nationwide clean-up success as it was a winner of the 2007 revitalization award from the Environmental Protection Agency. The RMA was originally about 27 square miles in the greater Denver area, of which 1 square mile was transformed into the wildlife refuge. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process was demonstrated in chart format. The presentation concluded with a discussion of lessons learned, such as sharing a mutual goal, and assuming that a mutually acceptable solution is possible. tabs., figs.

    Visitors utilize the urban space based on their thermal perception and thermal environment. The thermal adaptation engages the user's behavioural, physiological and psychological aspects. These aspects play critical roles in user's ability to assess the thermal environments. Previous studies have rarely addressed the effects of identified factors such as gender, age and locality on outdoor thermal comfort, particularly in hot, dry climate. This study investigated the thermal comfort of visitors at two city squares in Iran based on their demographics as well as the role of thermal environment. Assessing the thermal comfort required taking physical measurement and questionnaire survey. In this study, a non-linear model known as the neural network autoregressive with exogenous input (NN-ARX) was employed. Five indices of physiological equivalent temperature (PET), predicted mean vote (PMV), standard effective temperature (SET), thermal sensation votes (TSVs) and mean radiant temperature ( T mrt) were trained and tested using the NN-ARX. Then, the results were compared to the artificial neural network (ANN) and the adaptive neuro-fuzzy inference system (ANFIS). The findings showed the superiority of the NN-ARX over the ANN and the ANFIS. For the NN-ARX model, the statistical indicators of the root mean square error (RMSE) and the mean absolute error (MAE) were 0.53 and 0.36 for the PET, 1.28 and 0.71 for the PMV, 2.59 and 1.99 for the SET, 0.29 and 0.08 for the TSV and finally 0.19 and 0.04 for the T mrt.

    2005-01-01

    In the Japanese post WWII urban planning and design field, concerns for formal features regarding the sequential street-front visual image in new high-density urban spaces have been a rather subordinated subject. Famous New Town schemes such as Tsukuba Science City (1963), or Minato Mirai 21 (1965) for instance, are typical inland and reclaimed land examples that summarize the validity and limitations of functional zoning systems applied to these artificial urban developments for the last half century. In those examples, the interaction between space mobility and land use has not been explored sufficiently in order to create attractive street-front images, yet such interaction is essential to the way the cityscape and its character are perceived by the eye. However, current insight regarding the sustainable New Town paradigm has brought a renewed perspective regarding design policy of the pedestrian precinct. This study investigates the formal features of the sequential street-front image of Dutch late-medieval town examples which could help re-formulate the existing design policies regarding the quality of pedestrian space especially in the artificial reclaimed land design field. The purpose is to find out how the principles of those old high-density artificial environmental design models generate such effective interaction between mobility and land usage, creating an enriched aesthetic visual image of street-front space as a result.

    2016-12-01

    The effects of urban conditions on tree growth have been investigated in an increasing number of studies over the last decades, emphasizing the harsh environment of cities. Urban trees often grow in highly paved, compacted sites with consequently less soil moisture, higher soil temperatures, and greater vapor pressure deficits. However, there is still a knowledge gap regarding the impact of harsh paved environments on urban tree growth during drought years on the growth patterns of urban trees. The present study investigated the structure and growth of the common urban tree species small-leaved lime (Tilia cordata) at a highly paved public square (CPS) compared with a contrasting more open, greener square (OGS). Continuously, measured high precision dendrometer data along with meteorological data of the extreme dry and warm summer 2015 as well as dendrochronological data of the sampled trees were investigated to analyze tree growth during a drought year. The results highlight different tree dimensions and growth patterns of the trees at both sites, influenced by tree age and distinct site conditions. While the trees at OGS grew up to 2.5 mm from July until mid of August, the trees at CPS had only 0.4-mm diameter increment. After the initial expansion at CPS, tree diameter contracted again during summer to the point of shrinkage (up to 0.8 mm) at the end of our investigation. Further drought year analysis confirmed the patterns of significant stem growth reductions in the consecutive two years following the drought. A correlation analysis revealed that transpiration, air temperature, and vapor pressure deficit were negatively correlated with the daily diameter growth, whereas precipitation had a strong positive effect. Due to high transpiration rates associated with anisohydric water use behavior, T. cordata was able to provide evaporative cooling even during drought. However, this anisohydric behavior resulted in substantial growth decline afterwards especially at

  17. Living Near to Attractive Nature? A Well-Being Indicator for Ranking Dutch, Danish, and German Functional Urban Areas.

    2017-01-01

    While nature is widely acknowledged to contribute to people's well-being, nature based well-being indicators at city-level appear to be underprovided. This study aims at filling this gap by introducing a novel indicator based on the proximity of city-residents to nature that is of high-amenity. High-amenity nature is operationalized by combining unique systematic data on people's perceptions of what are the locations of attractive natural areas with data on natural land cover. The proposed indicator departs from the usual assumption of equal well-being from any nature, as it approximates the 'actual' subjective quality of nature near people's homes in a spatially explicit way. Such indicator is used to rank 148 'cities' in the Netherlands, Denmark, and Germany. International comparability of the indicator is enhanced by the use of a definition of cities as functional urban areas (FUAs), which are consistently identified across countries. Results demonstrate that the average 'nearness' of FUA populations to high amenity nature varies widely across the observed FUAs. A key finding, that complements insights from existing city-level indicators, is that while populations of FUAs with higher population densities may live relatively far from nature in general, they also live, on average, closer to high-amenity nature than inhabitants of lower density FUAs. Our results may stimulate policy-debates on how to combine urban agglomeration with access to natural amenities in order to account for people's wellbeing.

    Many problems concentrate in deprived neighbourhoods, among which is poor health. One possible way to address these health problems is to invest in the green space in deprived neighbourhoods. The number of evaluations of the public health impact of actual changes in neighbourhood green space is still limited. This study investigated the impact of real-life changes in the quality or quantity of green space in severely deprived neighbourhoods on physical activity and perceived general health. Repeated cross-sectional surveys from 2004 till 2011 yielded self-reported information on leisure time walking, cycling and sports, and perceived general health of 48,132 adult residents. We fitted generalised mixed models to assess the rate of change per half year, estimate the linear trend, and the change in trends before and after the start of the urban regeneration mid-2008. Using a quasi-experimental design, we compared the trends in the intervention neighbourhoods with different selections of control areas. The deprived neighbourhoods that intervened in green space did not show more favourable changes in the trend of physical activity and good general health compared to all the different groups of control areas. We did not observe short-term positive effects on physical activity and general health among adults from improvements in green space in deprived neighbourhoods. This suggests that greening interventions that have been carried out in the context of the Dutch District Approach did not achieve short-term health gains among adults.

  20. The soil-water system as basis for a climate proof and healthy urban environment: opportunities identified in a Dutch case-study.

    One of the effects of climate change expected to take place in urban areas in the Netherlands is an increase in periods of extreme heat and drought. How the soil can contribute to making cities more climate proof is often neglected. Unsealed soil and green spaces increase water storage capacity and can consequently prevent flooding. The planning of public or private green spaces can have a cooling effect and, in general, have a positive effect on how people perceive their health. This paper reviews existing guidelines from Dutch policy documents regarding unsealed soil and green spaces in the Netherlands; do they support climate adaptation policies? Scientific literature was used to quantify the positive effects of green spaces on water storage capacity, cooling and public health. Finally we present a case study of a model town where different policy areas are linked together. Maps were made to provide insight into the ratio of unsealed soil and the number of green spaces in relation to existing guidelines using Geographical Information Systems (GIS). Maps marking the age and social-economic status of the population were also made. The benefits of green spaces are difficult to express in averages because they depend on many different factors such as soil properties, type of green spaces, population characteristics and spatial planning. Moreover, it is not possible to provide quantifications of the benefits of green spaces because of a lack of scientific evidence at the moment. Based on the maps, however, policy assessments can be made, for example, in which site a neighborhood will most benefit from investment in parks and public gardens. Neighborhoods where people have a low social-economic status have for example fewer green spaces than others. This offers opportunities for efficient adaptation policies linking goals of several policy fields. Copyright © 2014 Elsevier B.V. All rights reserved.

    In the Netherlands audiological care is given at different stages. An attempt is made to screen the hearing of all Dutch babies between the ages of 8 and 12 months. At the age of 4 or over, general audiological care is given by the school medical service; referral is first to a family doctor, who may refer to an otolaryngologist. Curative medical care (examination and therapy) is the province of the family doctor and the otolaryngologist. Otolaryngologists and pediatricians can refer patients to one of 19 Audiological Centers distributed around the country, where a number of workers in different disciplines cooperate for habilitation and rehabilitation. These may include an otolaryngologist in charge, a psychologist, a speech and hearing therapist, an audiologist (usually a physicist or university-trained engineer), social worker, technician, ortho-pedagogue, audiology assistant, and teacher. There are at the moment 25 schools for the hard of hearing and 5 institutes for the deaf. These are often found in conjunction with Audiological Centers, the latter providing paramedical assistance to the pupils by agreement. Finally, the Dutch Organization for Preventive Medicine works to prevent hearing loss in noisy industries.

    Full Text Available Natal is a city with environment singularities. The urban legislation tried to preserve the features of the local landscape delimiting “Areas for Controlling Building High”, destined to protect the scenic value of some parts of the city. In 1979 was created a “NonÆdificandi” area to protect the scenery of Ponta Negra beach, one of the most famous view of the city. Since this time, the real state market, the building constructers and the land owners of this area have exerted constant pressure in sense to abolish or to modify this legal instrument.Nowadays, the public administration presented a new project which try to answer public and private interests.This paper is the result of an inclusion of the University in this polemic issue. Architecture and Urban Planning and Statistic students of two universities of the city (UFRN and UNP, helped the process collecting data and producing information. The proposed of the investigation was to know the users of this area and their opinion about the subject. It was done together with the Public agency, Secretaria Especial de Meio Ambiente e Urbanismo. At the end, the students presented their particular solutions for the problem, inside the disciplines of Landscaping and Urban Planning.

    Thomas, W.O.; Corley, R.K.

    1977-01-01

    Statewide regression equations are defined for estimating peak discharges of floods having recurrence intervals ranging from 2 to 500 years. Contributing drainage area, main-channel slope and mean annual precipitation are the independent variables required for estimating flood discharges for rural streams. For urban streams the percentage of the basin that is impervious and served by storm sewers also is required. The regression equations are applicable for watersheds draining less than 2,500 square miles (6,500 square kilometers) that are not significantly affected by regulation. For the rural streams, the regression equations are presented in graphical form for easy application. Calibration of the U.S. Geological Survey rainfall-runoff model and synthesis of long-term annual peak data for 60 small watersheds is discussed. Synthetic frequency curves, generated using six long-term rainfall stations, are combined into one frequency curve and weighted with the observed frequency curve at each site. Use of the rainfall-runoff model parameters to estimate flood discharges reduces the standard error for selected frequencies by 9-12 percent. However, collection of the necessary rainfall-runoff data to determine the model parameters is time consuming and expensive. Annual peak data, basin and climatic characteristics, log-Pearson Type III statistics, and the flood-frequency relations are presented for 188 gaging stations.

Let f(n) and g(n) denote the maximum values of the sum of the edge lengths of the n small squares, where in the case of f(n) the maximum is taken over all arbitrary packings of the unit square, and in the case of g(n) it is taken over all tilings of the unit square (i.e., the total area of the n small squares is 1). Benton and Tyler asked for which values of n we have f(n)=g(n). We show that f(8)>g(8). More precisely, we show that g(8)=13/5; it is known that f(8) is at least 8/3.

Veracious forecast of water consumption is very significant for the urban water resource use in a well-planned way. We also know that the urban water consumption is actually influenced by numerous factors, among which there stands the problem of relativities. To solve the problem of relativities, we have introduced a stepwise regression method into the partial least-square (PLS) regression analysis process for choosing the likely influential factors. The advantages of the two methods can be synthesized to improve the accounting power so that it can be used to predict the urban water consumption. Moreover, the improvement may allow the problem of mutual influence among the independent variables to be solved effectively without decreasing its accuracy. What is needed to do is to simplify the given model and refine it through dimension reduction. In so doing, the model innovated by us can be worked out by using a software named R. And make a comparative analysis between the simulated results of PLS model with the stepwise regression analysis by using the main influential factors and traditional PLS model with all its independent variables. The research shows that the precision of the former model in simulation can

    A square chiliagonal number is a number which is simultaneously a chiliagonal number and a perfect square (just as the well-known square triangular number is both triangular and square). In this work, we determine which of the chiliagonal numbers are perfect squares and provide the indices of the corresponding chiliagonal numbers and square numbers. The study revealed that the determination of square chiliagonal numbers naturally leads to a generalized Pell equation x2 - Dy2 = N with D = 1996 and N = 9962, and has six fundamental solutions out of which only three yielded integer values for use as indices of chiliagonal numbers. The crossing/independent recurrence relations satisfied by each class of indices of the corresponding chiliagonal numbers and square numbers are obtained. Finally, the generating functions serve as a clothesline to hang up the indices of the corresponding chiliagonal numbers and square numbers for easy display and this was used to obtain the first few sequence of square chiliagonal numbers.

    Cardiopulmonary bypass procedures remain complex, involving many potential risks. Therefore, a nationwide retrospective study was conducted to gain insight into the number of incidents and accidents in Dutch adult perfusion practice. An anonymous postal survey (85 questions about hardware, disposables, fluids and medication, air emboli, anticoagulation, practice, and safety measures) was sent to all Dutch perfusionists involved in adult cardiovascular perfusion during 2006 and 2007. To guarantee complete anonymity, respondents were asked to return the survey to a notary who discarded personal information. The net response rate was 72% and covered 23,500 perfusions. Individual respondents performed 240 ± 103 perfusions during the 2-year study period and had 13.8 ± 8.7 years of practical experience. The incident rate was 1 per 15.6 perfusions and the adverse event rate was 1 per 1,236 perfusions. The three most reported incidents were: (1) persistent inability to raise the activated coagulation time above 400s during perfusion (184 incidents); (2) an allergic or anaphylactic reaction to drugs, fluids, or blood products (114 incidents); and (3) clotting formation in the extracorporeal circuit (74 incidents). Furthermore, pre-bypass safety measures showed no statistically significant association with the reported incidents. In comparison with data from the recent literature, the reported number of incidents is high. Nevertheless, the adverse outcome rate is well matched to other published surveys. The relatively high response rate conveys the impression that the Dutch perfusionist is vigilant and willing to report incidents. Hence, a web-based Dutch perfusion incident registration system is recommended.

    OBJECTIVES OF THE THESISHeathlands in The Netherlands are vanishing due to the invasion of trees. The transition from heathland to woodland in Dutch heathlands may either proceed directly or is preceded by the development of an intermediate grass heath. These changes are due to natural succession in the absence of management. In addition to the absence of management atmospheric pollution i.e. increased inputs of nitrogen has accelerated the replacement of heather heath by grass heath.The main...

    Full Text Available The paper deals with changes in street names in the city of Zagreb. Taking the Lower Town (Donji grad city area as an example, the first part of the paper analyses diachronic street name changes commencing from the systematic naming of streets in 1878. Analysis of official changes in street names throughout Zagreb’s history resulted in categorisation of five periods of ideologically motivated naming/name-changing: 1. the Croatia modernisation period, when the first official naming was put into effect, with a marked tendency towards politicisation and nationalisation of the urban landscape; 2. the period of the Kingdom of the Serbs, Croatians and Slovenians/Yugoslavia, when symbols of the new monarchy, the idea of the fellowship of the Southern Slavs, Slavenophilism and the pro-Slavic geopolitical orientation were incorporated into the street names, and when the national idea was highly evident and remained so in that process; 3. the period of the NDH, the Independent State of Croatia, with decanonisation of the tokens of the Yugoslavian monarchy and the Southern Slavic orientation, and reference to the Ustashi and the German Nazi and Italian Fascist movement; 4. the period of Socialism, embedding the ideals and heroes of the workers’ movement and the War of National Liberation into the canonical system; and, 5. the period following the democratic changes in 1990, when almost all the signs of Socialism and the Communist/Antifascist struggle were erased, with the prominent presence of a process of installing new references to early national culture and historical tradition. The closing part of the paper deals with public discussions connected with the selection of a location for a square to bear the name of the first president of independent Croatia, Franjo Tuđman. Analysis of these public polemics shows two opposing discourses: the right-wing political option, which supports a central position for the square and considers the chosen area to

    1985-11-01

    This study focuses on hospital sisters in 30 Dutch hospitals. The so-called role-set approach has been adopted. In this approach the sisters are the focal persons. Direct superiors, specialists, registered nurses and student nurses acted as role-senders. The possible number of respondents is 600 (120 of each group). The response of hospital sisters is 100%, that of role-senders 88%. The study started out as an attempt to collect background information on the causes of wastage of sisters. High wastage rates are generally regarded as an indication of an unfavourable working environment. Since hospital sisters occupy a key position in hospitals, the ward problems will be studied from their angle. Although wastage rates have dropped recently, it does not necessarily follow that the working environment has improved. Wastage is known to act as a safety valve, thus allowing tensions to resolve. The threat of unemployment clogs this outlet, which increases the tensions on the hospital ward. Data from the study show that work overload is one of the major stress factors for sisters. Analyses demonstrated that there exists a relationship between work overload and tensions with the management and direct superiors, tensions in job execution, irritableness on the ward, low self-esteem, health complaints and psychological condition. Sisters with an excessive job involvement refer to work overload more often than their moderate colleagues. There is a relationship between an unfavourable working environment and irritableness of sisters.

The authors relate Dutch developments to initiatives abroad, some of which were taken up by Dutch psychiatrists and developed further. The development of the extensive network of out-patient mental health facilities in particular, which makes the Dutch system stand apart from that of most others, receives a lot of attention. Unfortunately, the history of psychiatry in the former Dutch colonial empire is not covered. The study is applauded for providing a wealth of material that could give a new impulse to discussions about the nature of mental health in the Netherlands, such as the following: How are supply and demand in mental health care related to each other? Do individuals with a lower socio-economic status have adequate access to care? How did the relationship between biological, social, and psychological approaches to mental illness and individual distress change over time?

    We consider dilaton--axion gravity interacting with $p\\;\\, U(1)$ vectors ($p=6$ corresponding to $N=4$ supergravity) in four--dimensional spacetime admitting a non--null Killing vector field. It is argued that this theory exibits features of a ``square'' of vacuum General Relativity. In the three--dimensional formulation it is equivalent to a gravity coupled $SO(2,2+p)/(SO(2)\\times SO(2+p))$. Kähler coordinates are introduced on the target manifold generalising Ernst potentials of General Relativity. The corresponding Kähler potential is found to be equal to the logarithm of the product of the four--dimensional metric component $g_{00}$ in the Einstein frame and the dilaton factor, independently on presence of vector fields. The complex axidilaton field, while it undergoes holomorphic/antiholomorphic transformations under general target space isometries. The ``square'' property is also manifest in the two--dimensional reduction of the theory as a matrix generalization of the Kramer--Neugebauer map.

    The ELMO Bumpy Square (EBS) concept consists of four straight magnetic mirror arrays linked by four high-field corner coils. Extensive calculations show that this configuration offers major improvements over the ELMO Bumpy Torus (EBT) in particle confinement, heating, transport, ring production, and stability. The components of the EBT device at Oak Ridge National Laboratory can be reconfigured into a square arrangement having straight sides composed of EBT coils, with new microwave cavities and high-field corners designed and built for this application. The elimination of neoclassical convection, identified as the dominant mechanism for the limited confinement in EBT, will give the EBS device substantially improved confinement and the flexibility to explore the concepts that produce this improvement. The primary goals of the EBS program are twofold: first, to improve the physics of confinement in toroidal systems by developing the concepts of plasma stabilization using the effects of energetic electrons and confinement optimization using magnetic field shaping and electrostatic potential control to limit particle drift, and second, to develop bumpy toroid devices as attractive candidates for fusion reactors. This report presents a brief review of the physics analyses that support the EBS concept, discussions of the design and expected performance of the EBS device, a description of the EBS experimental program, and a review of the reactor potential of bumpy toroid configurations. Detailed information is presented in the appendices.

    Aims: We develop a fully Bayesian least squares deconvolution (LSD) that can be applied to the reliable detection of magnetic signals in noise-limited stellar spectropolarimetric observations using multiline techniques. Methods: We consider LSD under the Bayesian framework and we introduce a flexible Gaussian process (GP) prior for the LSD profile. This prior allows the result to automatically adapt to the presence of signal. We exploit several linear algebra identities to accelerate the calculations. The final algorithm can deal with thousands of spectral lines in a few seconds. Results: We demonstrate the reliability of the method with synthetic experiments and we apply it to real spectropolarimetric observations of magnetic stars. We are able to recover the magnetic signals using a small number of spectral lines, together with the uncertainty at each velocity bin. This allows the user to consider if the detected signal is reliable. The code to compute the Bayesian LSD profile is freely available.

  6. Generalized conjugate gradient squared

    Energy Technology Data Exchange (ETDEWEB)

    Fokkema, D.R.; Sleijpen, G.L.G. [Utrecht Univ. (Netherlands)

    1994-12-31

    In order to solve non-symmetric linear systems of equations, the Conjugate Gradient Squared (CGS) is a well-known and widely used iterative method. In practice the method converges fast, often twice as fast as the Bi-Conjugate Gradient method. This is what you may expect, since CGS uses the square of the BiCG polynomial. However, CGS may suffer from its erratic convergence behavior. The method may diverge or the approximate solution may be inaccurate. BiCGSTAB uses the BiCG polynomial and a product of linear factors in an attempt to smoothen the convergence. In many cases, this has proven to be very effective. Unfortunately, the convergence of BiCGSTAB may stall when a linear factor (nearly) degenerates. BiCGstab({ell}) is designed to overcome this degeneration of linear factors. It generalizes BiCGSTAB and uses both the BiCG polynomial and a product of higher order factors. Still, CGS may converge faster than BiCGSTAB or BiCGstab({ell}). So instead of using a product of linear or higher order factors, it may be worthwhile to look for other polynomials. Since the BiCG polynomial is based on a three term recursion, a natural choice would be a polynomial based on another three term recursion. Possibly, a suitable choice of recursion coefficients would result in method that converges faster or as fast as CGS, but less erratic. It turns out that an algorithm for such a method can easily be formulated. One particular choice for the recursion coefficients leads to CGS. Therefore one could call this algorithm generalized CGS. Another choice for the recursion coefficients leads to BiCGSTAB. It is therefore possible to mix linear factors and some polynomial based on a three term recursion. This way one may get the best of both worlds. The authors will report on their findings.

    Full Text Available Compares slave trading and slavery in the Dutch colonial empire, specifically between the former trading and territorial domains of the West India Company (WIC, the Americas and West Africa, and of the East India Company (VOC, South East Asia, the Indian Ocean region, and South and East Africa. Author presents the latest quantitative assessments concerning the Dutch transatlantic as well as Indian Ocean World slave trade, placing the volume, direction, and characteristics of the forced migration in a historical context. He describes how overall the Dutch were a second-rate player in Atlantic slavery, though in certain periods more important, with according to recent estimates a total of about 554.300 slaves being transported by the Dutch to the Americas. He indicates that while transatlantic slave trade and slavery received much scholarly attention resulting in detailed knowledge, the slave trade and slavery in the Indian Ocean World by the Dutch is comparatively underresearched. Based on demand-side estimates throughout Dutch colonies of the Indonesian archipelago and elsewhere, he deduces that probably close to 500.000 slaves were transported by the Dutch in the Indian Ocean World. In addition, the author points at important differences between the nature and contexts of slavery, as in the VOC domains slavery was mostly of an urban and domestic character, contrary to its production base in the Americas. Slavery further did in the VOC areas not have a rigid racial identification like in WIC areas, with continuing, postslavery effects, and allowed for more flexibility, while unlike the plantation colonies in the Caribbean, as Suriname, not imported slaves but indigenous peoples formed the majority. He also points at relative exceptions, e.g. imported slaves for production use in some VOC territories, as the Banda islands and the Cape colony, and a certain domestic and urban focus of slavery in Curaçao.

Besides the known Freudenthal-Rozenfeld-Tits MS, the single-split G\\"unaydin-Sierra-Townsend MS, and the double-split Barton-Sudbery MS, we obtain other 7 Euclidean and 10 Lorentzian novel MS's. We elucidate the role and the meaning of the various non-compact real forms of Lie algebras, entering the MS's as symmetries of theories of Einstein-Maxwell gravity coupled to non-linear sigma models of scalar fields, possibly endowed with local supersymmetry, in D = 3, 4 and 5 space-time dimensions. In particular, such symmetries can be recognized as the U-dualities or the stabilizers of scalar manifolds within space-time with standard Lorentzian signature or with other, more exotic signatures, also relevant to suitable compactifications of the so-called M*- and M'- theories.

    Full Text Available ResumenEste artículo recoge los resultados del estudio de las características físicas, funcionales y climáticas de tres plazas de la ciudad de Madrid, así como el uso que las personas hicieron de ellas durante los meses de primavera. Los resultados muestran la relación existente entre los condicionantes físicos y ambientales y el modo de ocupación del espacio por parte de los ciudadanos en los días analizados, pero también ponen de manifiesto la dificultad de generalizar el concepto de confort en el espacio público. En el presente trabajo se ha verificado la utilidad de ciertas herramientas de caracterización climática de plazas y se ha puesto de manifiesto que aquellas plazas que ofrecen al ciudadano una mayor mezcla de posibilidades en lo referente a situarse en lugares con condiciones microclimáticas y posibilidades de utilización del espacio diversas han sido los más empleados durante los periodos analizados. Así, se evidencia la necesidad de conservación y creación de la ciudad compleja, con mezcla de usos y que ofrece al ciudadano la posibilidad de elección, transformándose así, en un lugar más habitable y democrático.Palabras clave Plazas, primavera, mezcla de posibilidades, condiciones ambientales, herramientas climáticas, ciudad compleja. AbstractThis article presents the results of the study of physical, functional and climatic properties of three public squares in the city of Madrid, and the use people made of them during the 2010 spring months.

    The SKA is an observatory for m/cm wavelengths that will provide quantum leaps in studies of the early universe, the high-energy universe, and astrobiology. Key science areas include:(1) Galaxy Evolution and Large-Scale Structure, including Dark Energy;(2) Probing the Dark Ages through studies of highly redshifted hydrogen and carbon monoxide;(3) Cosmic magnetism;(4) Probing Gravity with Pulsars and Black Holes; and(5) The Cradle of Life, including real-time images of protoplanetary disks, inventory of organic molecules, and the search for signals from extraterrestrial intelligence.From a phase-space point of view, the SKA will expand enormously our ability to discover new and known phenomena, including transient sources with time scales from nano-seconds to years. Particular examples include coherent emissions from extrasolar planets and gamma-ray burst afterglows, detectable at levels 100 times smaller than currently. Specifications needed to meet the science requirements are technically quite challenging: a frequency range of approximately 0.1 to 25 GHz; wide field of view, tens of square degrees (frequency dependent); high dynamic range and image fidelity; flexibility in imaging on scales from sub-mas to degrees; and sampling the time-frequency domain as demanded by transient objects. Meeting these specifications requires collaboration of a world-wide group of engineers and scientists. For this and other reasons, the SKA will be realized internationally. Initially, several concepts have been explored for building inexpensive collecting area that provides broad frequency coverage. The Reference Design now specifies an SKA based on a large number of small-diameter dish antennas with "smart feeds." Complementary to the dishes is a phased aperture array that will provide very wide-field capability. I will discuss the Reference Design, along with a timeline for developing the technology, building the first 10% of the SKA, and finishing the full SKA, along with the

  3. A Dutch Confederate: Charles Liernur Defends Slavery in America

    Full Text Available In the 1850s and 1860s, Dutch immigrants in America struggled to square their racial views with the politics of slavery in their new country. The historiography of the Dutch world would benefit from incorporating this story, because it is often in moments of conflict when the most explicit expressions of ideology present themselves. The letters of Charles Liernur, a Dutch-born Confederate, provide a unique insight into the mind of an explicit supporter of slavery in an American context. How and why a Dutchman could defend slavery is the primary question this article addresses. Building on Liernur’s story, this article also challenges the standard view that Dutch Americans were natural opponents of slavery. Instead, they held diverse and ambiguous views, shaped in part by the circumstances of their settlement.Een Nederlandse Confederate: Charles Liernur verdedigt slavernij in AmerikaIn de jaren vijftig en zestig van de negentiende eeuw hadden Nederlandse immigranten in Amerika grote moeite een standpunt in te nemen met betrekking tot de slavernij. Een analyse daarvan lijkt van belang voor de Nederlandse geschiedschrijving, omdat ideologische overtuigingen vaak tijdens conflicten op scherpe wijze uitgedragen worden. De brieven van Charles Liernur, een Nederlandse ‘Confederate’, bieden een unieke blik op de denkwereld van eenuitgesproken voorstander van de slavernij. Hoe en waarom kon een Nederlander zo fel de slavernij verdedigen? Dat is de centrale vraag waarop dit artikel een antwoord probeert te geven. Het verhaal van Liernur laat zien dat de gangbare visie, dat Nederlandse Amerikanen van nature tegenstanders van de slavernij waren, niet klopt. Immigranten hadden veeleer uiteenlopende en ambigue meningen over slavernij, bepaald door de omstandigheden waarmee ze in hun nieuwe vaderland te maken kregen.

    Since the introduction of a design methodology for Dutch banknotes, the quality of Dutch paper currency has improved in more than one way. The methodology is question provides for (i) a design policy, which helps fix clear objectives; (ii) design management, to ensure a smooth cooperation between the graphic designer, printer, papermaker an central bank, (iii) a program of requirements, a banknote development guideline for all parties involved. This systematic approach enables an objective selection of design proposals, including security features. Furthermore, the project manager obtains regular feedback from the public by conducting market surveys. Each new design of a Netherlands Guilder banknote issued by the Nederlandsche Bank of the past 50 years has been an improvement on its predecessor in terms of value recognition, security and durability.

  13. Perception of Length to Width Relations of City Squares

    Directory of Open Access Journals (Sweden)

    Harold T. Nefs

    2013-04-01

    Full Text Available In this paper, we focus on how people perceive the aspect ratio of city squares. Earlier research has focused on distance perception but not so much on the perceived aspect ratio of the surrounding space. Furthermore, those studies have focused on “open” spaces rather than urban areas enclosed by walls, houses and filled with people, cars, etc. In two experiments, we therefore measured, using a direct and an indirect method, the perceived aspect ratio of five city squares in the historic city center of Delft, the Netherlands. We also evaluated whether the perceived aspect ratio of city squares was affected by the position of the observer on the square. In the first experiment, participants were asked to set the aspect ratio of a small rectangle such that it matched the perceived aspect ratio of the city square. In the second experiment, participants were asked to estimate the length and width of the city square separately. In the first experiment, we found that the perceived aspect ratio was in general lower than the physical aspect ratio. However, in the second experiment, we found that the calculated ratios were close to veridical except for the most elongated city square. We conclude therefore that the outcome depends on how the measurements are performed. Furthermore, although indirect measurements are nearly veridical, the perceived aspect ratio is an underestimation of the physical aspect ratio when measured in a direct way. Moreover, the perceived aspect ratio also depends on the location of the observer. These results may be beneficial to the design of large open urban environments, and in particular to rectangular city squares.

    A new method for Total Least Squares (TLS) problems is presented. It differs from previous approaches and is based on the solution of successive Least Squares problems.The method is quite suitable for Structured TLS (STLS) problems. We study mostly the case of Toeplitz matrices in this paper. The numerical tests illustrate that the method converges to the solution fast for Toeplitz STLS problems. Since the method is designed for general TLS problems, other structured problems can be treated similarly.

    Science.gov (United States)

    Kantak, A. V.

    1994-01-01

    The Least Squares Curve Fitting program, AKLSQF, computes the polynomial which will least square fit uniformly spaced data easily and efficiently. The program allows the user to specify the tolerable least squares error in the fitting or allows the user to specify the polynomial degree. In both cases AKLSQF returns the polynomial and the actual least squares fit error incurred in the operation. The data may be supplied to the routine either by direct keyboard entry or via a file. AKLSQF produces the least squares polynomial in two steps. First, the data points are least squares fitted using the orthogonal factorial polynomials. The result is then reduced to a regular polynomial using Sterling numbers of the first kind. If an error tolerance is specified, the program starts with a polynomial of degree 1 and computes the least squares fit error. The degree of the polynomial used for fitting is then increased successively until the error criterion specified by the user is met. At every step the polynomial as well as the least squares fitting error is printed to the screen. In general, the program can produce a curve fitting up to a 100 degree polynomial. All computations in the program are carried out under Double Precision format for real numbers and under long integer format for integers to provide the maximum accuracy possible. AKLSQF was written for an IBM PC X/AT or compatible using Microsoft's Quick Basic compiler. It has been implemented under DOS 3.2.1 using 23K of RAM. AKLSQF was developed in 1989.

    In 2009, the nationwide Dutch Surgical Colorectal Audit (DSCA) was initiated by the Association of Surgeons of the Netherlands (ASN) to monitor, evaluate and improve colorectal cancer care. The DSCA is currently widely used as a blueprint for the initiation of other audits, coordinated by the Dutch Institute for Clinical Auditing (DICA). This article illustrates key elements of the DSCA and results of three years of auditing. Key elements include: a leading role of the professional association with integration of the audit in the national quality assurance policy; web-based registration by medical specialists; weekly updated online feedback to participants; annual external data verification with other data sources; improvement projects. In two years, all Dutch hospitals participated in the audit. Case-ascertainment was 92% in 2010 and 95% in 2011. External data verification by comparison with the Netherlands Cancer Registry (NCR) showed high concordance of data items. Within three years, guideline compliance for diagnostics, preoperative multidisciplinary meetings and standardised reporting increased; complication-, re-intervention and postoperative mortality rates decreased significantly. The success of the DSCA is the result of effective surgical collaboration. The leading role of the ASN in conducting the audit resulted in full participation of all colorectal surgeons in the Netherlands. By integrating the audit into the ASNs' quality assurance policy, it could be used to set national quality standards. Future challenges include reduction of administrative burden; expansion to a multidisciplinary registration; and addition of financial information and patient reported outcomes to the audit data.

    The Dutch parliament has recently accepted a tax law in which certain groups of alternative therapists can be exempt from VAT. To be eligible for this VAT exemption, the disciplines to which the therapists belong have to meet certain training requirements. In this article it is contended, in agreement with the Royal College of Physicians in the UK, that statutory regulation is inappropriate for disciplines whose therapies are neither of proved benefit nor appropriately tested. It legitimizes harmful therapies. This is illustrated by two serious accidents, previously described in this journal, caused by a chiropractor and a craniosacral therapist.

    Drawing on the authors' substantial expertise in modeling longitudinal and clustered data, Quasi-Least Squares Regression provides a thorough treatment of quasi-least squares (QLS) regression-a computational approach for the estimation of correlation parameters within the framework of generalized estimating equations (GEEs). The authors present a detailed evaluation of QLS methodology, demonstrating the advantages of QLS in comparison with alternative methods. They describe how QLS can be used to extend the application of the traditional GEE approach to the analysis of unequally spaced longitu

  4. In How Far is Elckerlijc Dutch? References to the Dutch Origin in the Polish Reception of the Middle Dutch Text

    Directory of Open Access Journals (Sweden)

    Dowlaszewicz Małgorzata

    2016-11-01

    Full Text Available The sixteenth-century morality play Elckerlijc is one of the few texts mentioned in almost all Dutch canon lists. It is no surprise that this is one of the few medieval Dutch texts transferred into different languages and cultures. There are two Polish texts based on it, the first from 1921 by Jarosław Iwaszkiewicz (Kwidam, the second from 1933 by Stanisław Helsztyński (Każdy (Everyman: średniowieczny moralitet angielski. The text was though never directly translated into Polish from Dutch. The main issue is whether these translations have influenced the image of Dutch literature in Poland. It appears that secondary literature has seen the plays of Iwaszkiewicz and Helsztyński only as transfer of German or English literature and ideas and that it is rarely known that the original story originates from the Netherlands.

    Full Text Available Aim: To determine whether the subjective oral health (SOH of the Dutch adult population was associated with clinical and demographic variables. Methods: A clinical examination was conducted in a sample of 1,018 people from the Dutch city of ‘s-Hertogenbosch. SOH was measured using the Dutch translation of the short form of the Oral Health Impact Profile (OHIP-NL14. Results: The average score on the OHIP-NL14 was 2.8 ± 5.9 and 51% of the respondents had a score of 0. Dental status was the most important predictor of SOH. Conclusions:  The SOH in the Dutch adult population was much better than in groups of adults in Australia, the United Kingdom and New Zealand. Nevertheless, there were important variations in SOH related to dental and socio-economic status.

    The main development approaches and some technologies developed in support of the different objectives of the Dutch Utilization Center (DUC) are reported. The DUC acts as a point of coordination of Dutch user support activities. The support needs of the user are analyzed and from there the required support efforts of the entities in the Dutch User Support Organization (DUSO) are activated. The main objectives of the DUSO are to promote the availability of the Columbus Space Station infrastructure among potential Dutch users, and to assist the users during the process of experiment definition, development, execution, and results evaluation. The DUSO support activities cover promotion and familiarization, and administrative, scientific, technical, and operational support to microgravity and space experimentation. The DUC developmental approaches consist of two approaches: a top down or formal approach; and a bottom up approach.

  20. Partial least squares methods: partial least squares correlation and partial least square regression.

    Science.gov (United States)

    Abdi, Hervé; Williams, Lynne J

    2013-01-01

    Partial least square (PLS) methods (also sometimes called projection to latent structures) relate the information present in two data tables that collect measurements on the same set of observations. PLS methods proceed by deriving latent variables which are (optimal) linear combinations of the variables of a data table. When the goal is to find the shared information between two tables, the approach is equivalent to a correlation problem and the technique is then called partial least square correlation (PLSC) (also sometimes called PLS-SVD). In this case there are two sets of latent variables (one set per table), and these latent variables are required to have maximal covariance. When the goal is to predict one data table the other one, the technique is then called partial least square regression. In this case there is one set of latent variables (derived from the predictor table) and these latent variables are required to give the best possible prediction. In this paper we present and illustrate PLSC and PLSR and show how these descriptive multivariate analysis techniques can be extended to deal with inferential questions by using cross-validation techniques such as the bootstrap and permutation tests.

  1. Radioactivity in Dutch consumer products

    CERN Document Server

    Janssen, M P M

    2002-01-01

    This study took place within the framework of a general update of the average radiation dose for the Dutch population. It focuses on consumer products in which radionuclides have been intentionally incorporated and on radiation-emitting devices that can be supplied to members of the public without special surveillance. Eleven consumer products were studied in more detail. The radiation from these products determined 90% of the total collective dose due to consumer products in the Netherlands in 1988. Individual and collective doses are presented here for each product. The total collective dose has decreased from 130 personSv in 1988 to 4.6 personSv at present. This reduction was attributed to: a decrease in the number of radioactive products (gas mantles), lower estimates of the number of radioactive products present in the Netherlands thanks to new information (camera lenses, smoke detectors containing Ra-226), replacement of radioactive by non-radioactive products (gas mantles, dental protheses), and a lowe...

  6. DNA barcoding of Dutch birds

    2013-12-01

    Full Text Available The mitochondrial cytochrome c-oxidase subunit I (COI can serve as a fast and accurate marker for the identification of animal species, and has been applied in a number of studies on birds. We here sequenced the COI gene for 387 individuals of 147 species of birds from the Netherlands, with 83 species being represented by >2 sequences. The Netherlands occupies a small geographic area and 95% of all samples were collected within a 50 km radius from one another. The intraspecific divergences averaged 0.29% among this assemblage, but most values were lower; the interspecific divergences averaged 9.54%. In all, 95% of species were represented by a unique barcode, with 6 species of gulls and skua (Larus and Stercorariusat least one shared barcode. This is best explained by these species representing recent radiations with ongoing hybridization. In contrast, one species, the Lesser Whitethroat Sylvia curruca showed deep divergences, averaging 5.76% and up to 8.68% between individuals. These possibly represent two distinct taxa, S. curruca and S. blythi, both clearly separated in a haplotype network analysis. Our study adds to a growing body of DNA barcodes that have become available for birds, and shows that a DNA barcoding approach enables to identify known Dutch bird species with a very high resolution. In addition some species were flagged up for further detailed taxonomic investigation, illustrating that even in ornithologically well-known areas such as the Netherlands, more is to be learned about the birds that are present.

  7. Tolerance at arm's length: the Dutch experience.

    Science.gov (United States)

    Schuijer, J

    1990-01-01

    With respect to pedophilia and the age of consent, the Netherlands warrants special attention. Although pedophilia is not as widely accepted in the Netherlands as sometimes is supposed, developments in the judicial practice showed a growing reservedness. These developments are a spin-off of related developments in Dutch society. The tolerance in the Dutch society has roots that go far back in history and is also a consequence of the way this society is structured. The social changes of the sixties and seventies resulted in a "tolerance at arm's length" for pedophiles, which proved to be deceptive when the Dutch government proposed to lower the age of consent in 1985. It resulted in a vehement public outcry. The prevailing sex laws have been the prime target of protagonists of pedophile emancipation. Around 1960, organized as a group, they started to undertake several activities. In the course of their existence, they came to redefine the issue of pedophilia as one of youth emancipation.

  18. Urban Scaling of Cities in the Netherlands

    CERN Document Server

    van Raan, Anthony F J; Goedhart, Willem

    2015-01-01

    We investigated the socioeconomic scaling behavior of cities in the Netherlands and found significant nonlinear correlations between gross urban product as well as number of jobs with population size. This nonlinearity manifested by a super-linear power law scaling is found for both the cities defined as municipalities and for the agglomerations of major cities. We used two types of agglomerations as defined by the Netherlands Central Bureau of Statistics: the direct agglomeration, i.e. the central city (municipality) with the adjacent suburbs (which are separate municipalities); and the larger urban area of the same major cities. The exponents are all similar, with values around 1.20. Remarkably, the agglomerations of cities underperform as compared to a city which is one municipality with the same population as the agglomeration. This effect is larger for the second type of agglomerations, the urban areas. We think this finding has important implications for the current Dutch urban policy. A residual analys...

These interacting factors constitute so-called “urban vulnerability” which town planners use in order to contribute to the field in the form of analysis definition and interventions in the mitigation of seismic risk on an urban scale. The research paper “Relational Spaces as Safe Places” positions itself firmly in the vein of town planning research which focuses on the mitigation of seismic risk, and which intends to blaze a new methodological trail that aims to identify safety traits in urban spaces. The research paper’s starting point is the assumption that empty urban spaces, given the indications provided by the principal organs for Civic Protection, have come to be seen as the spaces designed to accommodate the public in cases of emergency. This can generate new thought regarding town planning by reviewing early post-earthquake urban designs where the rules were laid out for earthquake-proof cities: a “chessboard” plan with wide streets, both straight and perpendicular, empty spaces like squares and markets positioned along the longitudinal streets, and buildings with regular layouts all at right-angles. These simple guidelines, which are often disregarded and distorted in modern towns, are extraordinarily relevant and oriented towards new definitions of the urban traits of quality and security.

  14. A Novel Latin Square Image Cipher

    CERN Document Server

    Wu, Yue; Noonan, Joseph P; Agaian, Sos; Chen, C L Philip

    2012-01-01

    In this paper, we introduce a symmetric-key Latin square image cipher (LSIC) for grayscale and color images. Our contributions to the image encryption community include 1) we develop new Latin square image encryption primitives including Latin Square Whitening, Latin Square S-box and Latin Square P-box ; 2) we provide a new way of integrating probabilistic encryption in image encryption by embedding random noise in the least significant image bit-plane; and 3) we construct LSIC with these Latin square image encryption primitives all on one keyed Latin square in a new loom-like substitution-permutation network. Consequently, the proposed LSIC achieve many desired properties of a secure cipher including a large key space, high key sensitivities, uniformly distributed ciphertext, excellent confusion and diffusion properties, semantically secure, and robustness against channel noise. Theoretical analysis show that the LSIC has good resistance to many attack models including brute-force attacks, ciphertext-only at...

  15. Enhancing building footprints with squaring operations

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Whatever the data source, or the capture process, the creation of a building footprint in a geographical dataset is error prone. Building footprints are designed with square angles, but once in a geographical dataset, the angles may not be exactly square. The almost-square angles blur the legibility of the footprints when displayed on maps, but might also be propagated in further applications based on the footprints, e.g., 3D city model construction. This paper proposes two new methods to square such buildings: a simple one, and a more complex one based on nonlinear least squares. The latter squares right and flat angles by iteratively moving vertices, while preserving the initial shape and position of the buildings. The methods are tested on real datasets and assessed against existing methods, proving the usefulness of the contribution. Direct applications of the squaring transformation, such as OpenStreetMap enhancement, or map generalization are presented.

  16. Quantity of plant leaf area on three major public squares in Kunming City, China

    DONGYan; ZHAOLin-sen; ZHAOYu-xiang

    2004-01-01

    Regressive formulae to calculate the quantity of plant leaf area for 13 species of ornamental plants were set up based on investigation data of 30 species on 3 major public squares (Dongfeng square, Shengli square and Guandu square) in Kunruing City, China, which were applied to calculate quantities of plant leaf area of these 13 species. The quantities of plant leaf area for the other 17 ornamental plant species on these squares were directly measured, and the total quantity of plant leaf area of each studied square was obtained individually. The results showed that the quantity of plant leaf area on Shengli square with ornamental plants structure composed of arbor tree species, shrub tree species and turf grass was highest among the three squares. It is believed that the design model of multi-storied vertical structure and proper tending of plant community could not only increase the quantity of plant leaf area, but also play an important role in generating ecological and landscaping benefits.Some corresponding suggestions were put forward on the basis of comprehensive analyses on the plant leaf area quantity of the three representative squares in Kunming urban area.

    2006-11-01

    The aim of this study was to gain deeper insight into relational aspects of the medical communication pattern in intercultural consultations at GP practices in the Netherlands. We ask whether there are differences in the verbal interaction of Dutch GPs with immigrant and Dutch patients. Data were drawn from 144 adult patient interviews and video observations of consultations between the patients and 31 Dutch GPs. The patient group consisted of 61 non-Western immigrants (Turkish, Moroccan, Surinamese, Antillean, Cape Verdian) and 83 Dutch participants. Affective and instrumental aspects of verbal communication were assessed using Roter's Interaction Analysis System (RIAS). Patients' cultural background was assessed by ethnicity, language proficiency, level of education, religiosity and cultural views (in terms of being more traditional or more modern). Consultations with the non-Western immigrant patients (especially those from Turkey and Morocco) were well over 2 min shorter, and the power distance between GPs and these patients was greater when compared to the Dutch patients. Major differences in verbal interaction were observed on the affective behavior dimensions, but not on the instrumental dimensions. Doctors invested more in trying to understand the immigrant patients, while in the case of Dutch patients they showed more involvement and empathy. Dutch patients seemed to be more assertive in the medical conversation. The differences are discussed in terms of patients' ethnic background, cultural views (e.g. practicing a religion) and linguistic barriers. It is concluded that attention to cultural diversity does matter, as this leads to different medical communication patterns. A two-way strategy is recommended for improving medical communication, with implications for both doctor and patient behavior.

    Both children with specific language impairment (SLI) and children who acquire a second language (L2) make errors with verb inflection. This overlap between SLI and L2 raises the question if verb inflection can discriminate between L2 children with and without SLI. In this study we addressed this question for Dutch. The secondary goal of the study was to investigate variation in error types and error profiles across groups. Data were collected from 6-8-year-old children with SLI who acquire Dutch as their first language (L1), Dutch L1 children with a typical development (TD), Dutch L2 children with SLI, and Dutch L1 TD children who were on average 2 years younger. An experimental elicitation task was employed that tested use of verb inflection; context (3SG, 3PL) was manipulated and word order and verb type were controlled. Accuracy analyses revealed effects of impairment in both L1 and L2 children with SLI. However, individual variation indicated that there is no specific error profile for SLI. Verb inflection use as measured in our study discriminated fairly well in the L1 group but classification was less accurate in the L2 group. Between-group differences emerged furthermore for certain types of errors, but all groups also showed considerable variation in errors and there was not a specific error profile that distinguished SLI from TD.

    The sixties have not only witnessed the start of the Dutch Society for Immunology (NvvI), but were also the flourishing beginning of the discipline of transplant immunology. The interest in immunology in the Netherlands had its start in the context of blood transfusions and not for instance in the field of infectious disease, as in many other countries. It began in the 1950-ties thanks to Joghem van Loghem at that time director of the Central Laboratory of Blood Transfusion in Amsterdam. The discoveries of these times have had major impact for transfusion medicine, hematopoietic stem cell transplantation and organ transplantation. In this review we will look back at some early highlights of Dutch transplant immunology and put them in the perspective of some recent developments.

    2010-10-01

    Fear of suffocation and fear of restriction are thought to underlie claustrophobia and can be assessed with the Claustrophobia Questionnaire (CLQ; Radomsky et al., 2001). A first study tested the psychometric properties of a Dutch version of the CLQ. Students (N=363) completed a Dutch translation of the CLQ and a set of other questionnaires assessing other specific fears, anxiety or depression. Results confirmed the two-factor structure and showed that the Dutch version of the CLQ has good psychometric properties. A second study tested the predictive validity of the Dutch CLQ. Participants (N=23) were exposed each to nine claustrophobic situations with elements of suffocation, restriction or both. The Dutch CLQ was found to be a significant predictor of fear and respiratory reactivity during claustrophobic exposure. It can be concluded that the Dutch version of the CLQ is a reliable and valid instrument to assess claustrophobic fear. Copyright 2010 Elsevier Ltd. All rights reserved.

  11. Extraction in Dutch with Lexical Rules

    CERN Document Server

    Rentier, G

    1994-01-01

    Unbounded dependencies are often modelled by ``traces'' (and ``gap threading'') in unification-based grammars. Pollard and Sag, however, suggest an analysis of extraction based on lexical rules, which excludes the notion of traces (P&S 1994, Chapter 9). In parsing, it suggests a trade of indeterminism for lexical ambiguity. This paper provides a short introduction to this approach to extraction with lexical rules, and illustrates the linguistic power of the approach by applying it to particularly idiosyncratic Dutch extraction data.

    Full Text Available In the Lithuanian acts of law and in the scientific literature there are no clear criteria and notions to define a square. The unbuilt city space places or the gaps between buildings are often defined as the squares, which do not have clear limits or destination. The mandatory attributes of the place which is called the square are indicated in the article, the notion of square is defined. The article deals with Lithuanian squares theme, analyses the differences between representation and representativeness. The article aims to indicate an influence of city environmental context and monument in the square on its function. The square is an independent element of city plan structure, but it is not an independent element of city spatial structure. The space and environment of the square are related to each other not only by physical, aesthetical relations, but as well as by causalities, which may be named as the essences of squares’ formation. The interdisciplinary discourse analysis method is applied in the article.

    Full Text Available Dutch, a West-Germanic language, is spoken by approximately 23 million people worldwide. In Europe, it is the language of all of the Netherlands and the northern part of Belgium, called Flanders. It is often said that since the Dutch and the Flemish speak Dutch differently, they in fact speak two different languages - Netherlandic Dutch and Belgian Dutch (Flemish. Linguists, however, argue they are not necessarily two separate languages but rather two varieties - a Netherlandic and a Belgian variety - of the same language, Dutch. Since there are a substantial number of grammatical, lexical, phonetic and even spelling differences between Belgian and Netherlandic Dutch, the question is whether Dutch is a pluricentric language with two centres of standardization or not. By explaining the socio-historical background of the Dutch language and giving a comprehensive overview of the differences between Netherlandic and Belgian Dutch, this article attempts to answer the aforementioned (research question.

    Adaptive filters play an important role in the fields related to digital signal processing and communication, such as system identification, noise cancellation, channel equalization, and beamforming. In practical applications, the computational complexity of an adaptive filter is an important consideration. The Least Mean Square (LMS) algorithm is widely used because of its low computational complexity (O(N)) and simplicity in implementation. The least squares algorithms, such as Recursive Least Squares (RLS), Conjugate Gradient (CG), and Euclidean Direction Search (EDS), can converge faster a

But how can entrepreneurs prosper in an environment that is not geared up towards such a change? And which strategies do they use to bend conditions in their favor? In this article we make use of the Market and System Failure Framework to analyze the pressures that entrepreneurs are confronted with when introducing sustainable innovations. We recognize that these pressures can be seen as bottlenecks, but that market and system failures can also create entrepreneurial opportunities. We interviewed 16 entrepreneurs in the Dutch construction industry to determine the influences they experienced from their environment and the strategies they use to deal with these. We conclude that we can distinguish between system building and following entrepreneurs, where the former aims to build a new system to challenge the old one, whereas the latter rather makes use of existing structures to build a business. We find that both strategies can be successful and that overall, the entrepreneurs confirm the belief that sustainability on people, planet and transparency aspects, can contribute very well to the long term profitability of the businesses the entrepreneurs are running. These in-depth insights into the influences from the context on the one hand, and the entrepreneurs’ strategic reactions on the other hand, contribute to our understanding of the interactions between entrepreneurs and the system context. This can help us to more effectively stimulate and support innovating entrepreneurs to contribute to the transition towards sustainability.

    The square centre of a given square is the point of intersection of its two diagonals. When two squares of different side lengths share the same square centre, there are in general four diagonals that go through the same square centre. The Two Squares Theorem developed in this paper summarizes some nice theoretical conclusions that can be obtained when two squares of different side lengths share the same square centre. These results provide the theoretical basis for two of the constructions given in the book of H.S. Hall and F.H. Stevens , 'A Shorter School Geometry, Part 1, Metric Edition'. In page 134 of this book, the authors present, in exercise 4, a practical construction which leads to a verification of the Pythagorean theorem. Subsequently in Theorems 29 and 30, the authors present the standard proofs of the Pythagorean theorem and its converse. In page 140, the authors present, in exercise 15, what amounts to a geometric construction, whose verification involves a simple algebraic identity. Both the constructions are of great importance and can be replicated by using the standard equipment provided in a 'geometry toolbox' carried by students in high schools. The author hopes that the results proved in this paper, in conjunction with the two constructions from the above-mentioned book, would provide high school students an appreciation of the celebrated theorem of Pythagoras. The diagrams that accompany this document are based on the free software GeoGebra. The author formally acknowledges his indebtedness to the creators of this free software at the end of this document.

  20. The Dutch model for legalizing end-of-life decisions.

    2003-01-01

    The Dutch experience with euthanasia is used as a model for other countries for regulating end-of-life decisions. Several elements of the Dutch debate, for example the definition of euthanasia, are copied and imported to other debates. This paper studies the specific Dutch construction of regulating euthanasia and the concept of the requirements of prudent practice. The requirements of prudent practice embody the conditions for careful medical management in end-of-life decisions. It is argued that the requirements of prudent practice are a relatively acceptable way of regulating the Dutch practice of euthanasia as they are embedded in an elaborate network of relations, standards and values. As a consequence of this local character and the way the requirements of prudent practice relate to the Dutch practice of euthanasia it is difficult to simply transport them to other countries in order to regulate euthanasia.

    The world population is ageing and healthcare services require trained staff who can address the needs of older patients. In this study we determined how current medical education prepares Dutch students of medicine in the field of Gerontology and Geriatrics (G&G). Using a checklist of the essentials of G&G, we assessed Dutch medical education on three levels. On the national level we analysed the latest National Blueprint for higher medical education (Raamplan artsopleiding 2009). On the faculty level we reviewed medical curricula on the basis of interviews with program directors and inspection of course materials. On the student level we assessed the topics addressed in the questions of the cross-institutional progress test (CIPT). The National Bluepr int contains few specific G&G objectives. Obligatory G&G courses in medical schools on average amount to 2.2% of the total curriculum measured as European Credit Transfer System units (ECTS). Only two out of eight medical schools have practical training during the Master phase in the form of a clerkship in G&G. In the CIPT, on average 1.5% of questions cover G&G. Geriatric education in the Netherlands does not seem to be in line with current demographic trends. The National Blueprint falls short of providing sufficiently detailed objectives for education on the care of older people. The geriatric content offered by medical schools is varied and incomplete, and students are only marginally tested on their knowledge of G&G in the CIPT.

    2014-11-01

    Full Text Available In this paper we discuss recent developments in administrative court proceedings in the Netherlands, called the New Approach. Along with developments leading to the New Approach, it became clear that the insights from research on procedural justice deserve particular attention. The goals of the judge's actions in this respect are both that the proceedings are fair and just and that parties perceive the way they are being treated during proceedings as fair and just.Within the New Approach we discern five procedural justice elements: (1 respect, (2 voice and due consideration, (3 some influence on how proceedings will continue, (4 an explanation of how the proceedings will continue and (5 direct interpersonal contact.The introduction of the New Approach shows two important bottlenecks in Dutch administrative court proceedings, which are (i the possible or supposed collision between legally right outcomes and  procedural justice and (ii the lack of uniformity and predictability.Although what we describe and discuss in this paper focuses on the Dutch situation, many of these considerations apply to administrative court proceedings in other countries. The themes and difficulties that face the administrative law judge seem to be common to many countries.

    2016-02-01

    Full Text Available This thesis proposes a framework for evaluating the mobility potential and performance of urban areas in the city region, as an instrument to support urban development that contributes positively to regional sustainable mobility objectives. The research takes a quantitative approach, modelling and measuring the characteristics of a city-region and of its individual urban areas, in terms of travel patterns and socioeconomic characteristics of the resident population, and in terms of built environment characteristics. It then explores how the built environment defines the affordances of urban areas for travelling by particular modes of transport, i.e. its walk-ability, cycleability, drive-ability and transit-ability, by developing a typology of what I call their ‘urban modality’. And finally the work combines this typology with the socio-economic characteristics of urban areas to determine their sustainable mobility potential and performance. It focuses on the case of the Randstad region of the Netherlands and its VINEX neighbourhoods, which are an emblematic example of new urban areas created under a policy programme with sustainable mobility objectives.A key stance in this work is the understanding that the location of an urban area in the region can be indicative of its population’s travel patterns, because the built environment (infrastructural and socio-economic characteristics are interrelated and present strong regional spatial patterns. What types of urban areas support sustainable travel patterns, and what are their spatial characteristics? How do new neighbourhoods compare to the best performing urban areas, and to other areas of the same ‘modality’ type? These are some of the questions addressed in this study. There are two main contributions of this research: the methods for building and analysing integrated multimodal network models, and the framework for contextual performance evaluation using urban area typologies

  13. Vertex micromagnetic energy in artificial square ice

    Perrin, Yann; Canals, Benjamin; Rougemaille, Nicolas

    2016-10-01

    Artificial arrays of interacting magnetic elements provide an uncharted arena in which the physics of magnetic frustration and magnetic monopoles can be observed in real space and in real time. These systems offer the formidable opportunity to investigate a wide range of collective magnetic phenomena with a lab-on-chip approach and to explore various theoretical predictions from spin models. Here, we study artificial square ice systems numerically and use micromagnetic simulations to understand how the geometrical parameters of the individual magnetic elements affect the energy levels of an isolated square vertex. More specifically, we address the question of whether the celebrated square ice model could be made relevant for artificial square ice systems. Our work reveals that tuning the geometry alone should not allow the experimental realization of the square ice model when using nanomagnets coupled through the magnetostatic interaction. However, low-aspect ratios combined with small gaps separating neighboring magnetic elements of moderated thickness might permit approaching the ideal case where the degeneracy of the ice rule states is recovered.

    William Wilde spent the final third of his life, from 1855 to 1876, in 1 Merrion Square. During the first half of his occupancy of the house his career blossomed to its fullest; the second decade, on the other hand, was marked by scandal, personal tragedy, and an unhappy professional and social decline. This paper considers the background to the development of Merrion Square, the architectural history of 1 Merrion Square from its building in 1762 to the arrival of the Wildes in 1855, the attractions and possibilities which the house offered for William Wilde, the major architectural expansion of the building which he commissioned in 1859, and aspects of his and his family's life in the house.

    Full Text Available The aim of present study was to show the main production parameters of sows based on 4359 crossbred Dutch Large White and Dutch Landrace pigs. The data were collected from 2004 to 2010 from Hungarian nucleus farms to analyze the lifetime performance of removed sows. The paper has studied the frequency of different culling reasons, the average lifespan of removed sows and the number of piglets born alive according to the parity. The result showed that the most frequent reasons for sow removal were the different fertility problems (29.5% and productivity problems (26.8%. In additional, it was detectable that the 35% of culling occured after the first farrowing or before this and there were removed 95% of the examined sows after the 8th parity. The highest litter size was observed at the 6th parity when the mean of lifespan of sows was 1210 days.

    Full Text Available In previous work, the authors derived a mathematical expression for the optimal (or "saturation" number of reinsurers for a given number of primary insurers (see Powers and Shubik, 2001. In the current article, we show analytically that, for large numbers of primary insurers, this mathematical expression provides a "square-root rule"; i.e., the optimal number of reinsurers in a market is given asymptotically by the square root of the total number of primary insurers. We note further that an analogous "fourth-root rule" applies to markets for retrocession (the reinsurance of reinsurance.

    Full Text Available Interest in self-esteem has been fuelled by the suggestion that level of self-esteem is associated with psychological well-being. In the present study, we translated the Rosenberg Self-Esteem Scale (RSES into the Dutch language and evaluated its psychometric properties in a sample of 442 adults. The results of both exploratory and confirmatory factor analyses confirmed that a single-factor solution provides the best fit. In addition, the Dutch RSES showed high internal consistency as well as high congruent validity. Overall, these findings support the usefulness of the Dutch RSES as a measure for global self-esteem.

  4. A validation of an operational wave and surge prediction system for the Dutch Coast

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Knowledge of the actual condition of hydrodynamics in the nearshore and coastal area is essential for coastal monitoring activities. To this end, a coastal operational model system can serve as a tool in providing recent and up-to-date state of the hydrodynamics along the coast. In this paper we apply CoSMoS (Coastal Storm Modeling System, a generic operational model system applied here to predict storm impact on dunes along the Dutch Coast. The CoSMoS application is not limited to storm impact prediction on the Dutch coast, but can also be applied to other coastal hazards such as rip currents and coastal flooding, in other environments. In this paper, we present the set-up of the CoSMoS system and validation of the wave and surge model within it using deep water wave buoy data and tidal gauge measurements as ground truth validation material. The evaluation is presented as monthly error measures between computed parameters and observed ones. Hindcast results over the whole year of 2009 show that the simulated wave parameters and surge elevation from the CoSMoS are in good agreement with data, with average root mean square error over the year of 0.14 m for the surge elevation and 0.24 m for the significant wave height. It is noted that there is a tendency of the wave model to underestimate the height of northerly waves with lower frequencies (swell. Additionally, when a wave separation algorithm is applied on the overall spectrum, results show consistent underestimation of the swell component by the model, which for the Dutch Coast, will mainly come from the North where the North Sea is open to the Atlantic Ocean. In the proposed model system, the swell boundary can have a significant effect on the simulated wave results, suggesting room for improvement for the swell boundary conditions on the North and the swell propagation within the Dutch Continental Shelf Model. Finally we show that in forecast mode, CoSMoS can provide reasonably good wave

    1999-01-01

    Hospitals in The Netherlands are governed by two boards: The Board of Directors, the legal representative of the hospital, responsible for strategic and operational business activities; and the Supervisory Board, made up of co-opted volunteers and responsible for checking and approving of the major decisions of the Board of Directors. The question which arises is whether the system of governance is able to function appropriately and guarantee enough concern about general health problems, moral and ethical questions and the interest of the patients. This paper investigate the successes and shortfalls of such a system of governance in Dutch hospitals. The results and conclusions determine that although copied from the corporate governance model, it does not function well in an environment where the influence of patients and the inhabitants of the region are of great importance and shareholders do not exist.

    2003-01-01

    Full Text Available Historical records provide direct information about the climatic impact on society. Especially great natural disasters such as river floods have been for long attracting the attention of humankind. Time series for flood development on the Rhine branches Waal, Nederrijn/Lek and IJssel in the Dutch Rhine Delta are presented in this paper. In the case of the Waal it is even possible to compare historical flood frequencies based on documentary data with the recent development reconstructed from standardized instrumental measurements. In brief, we will also discuss various parameters concerning the structure of the flood series and the "human dimension" of natural disaster, i.e. the vulnerability of society when facing natural disasters.

  7. Deformation analysis with Total Least Squares

    2006-01-01

    Full Text Available Deformation analysis is one of the main research fields in geodesy. Deformation analysis process comprises measurement and analysis phases. Measurements can be collected using several techniques. The output of the evaluation of the measurements is mainly point positions. In the deformation analysis phase, the coordinate changes in the point positions are investigated. Several models or approaches can be employed for the analysis. One approach is based on a Helmert or similarity coordinate transformation where the displacements and the respective covariance matrix are transformed into a unique datum. Traditionally a Least Squares (LS technique is used for the transformation procedure. Another approach that could be introduced as an alternative methodology is the Total Least Squares (TLS that is considerably a new approach in geodetic applications. In this study, in order to determine point displacements, 3-D coordinate transformations based on the Helmert transformation model were carried out individually by the Least Squares (LS and the Total Least Squares (TLS, respectively. The data used in this study was collected by GPS technique in a landslide area located nearby Istanbul. The results obtained from these two approaches have been compared.

    Mihaescu, Radu; Pachter, Lior

    2008-09-01

    A recurring theme in the least-squares approach to phylogenetics has been the discovery of elegant combinatorial formulas for the least-squares estimates of edge lengths. These formulas have proved useful for the development of efficient algorithms, and have also been important for understanding connections among popular phylogeny algorithms. For example, the selection criterion of the neighbor-joining algorithm is now understood in terms of the combinatorial formulas of Pauplin for estimating tree length. We highlight a phylogenetically desirable property that weighted least-squares methods should satisfy, and provide a complete characterization of methods that satisfy the property. The necessary and sufficient condition is a multiplicative four-point condition that the variance matrix needs to satisfy. The proof is based on the observation that the Lagrange multipliers in the proof of the Gauss-Markov theorem are tree-additive. Our results generalize and complete previous work on ordinary least squares, balanced minimum evolution, and the taxon-weighted variance model. They also provide a time-optimal algorithm for computation.

    A weighted least-squares problem with a very ill-conditioned weight matrix arises in many applications. Because of round-off errors, the standard conjugate gradient method for solving this system does not give the correct answer even after n iterations. In this paper we propose an iterative algorithm based on a new type of reorthogonalization that converges to the solution.

    In this paper we consider the least-squares (LS) fitting of the Gompertz curve to the given nonconstant data (pi,ti,yi), i=1,...,m, m≥3. We give necessary and sufficient conditions which guarantee the existence of the LS estimate, suggest a choice of a good initial approximation and give some numerical examples.

  18. Time Scale in Least Square Method

    Full Text Available Study of dynamic equations in time scale is a new area in mathematics. Time scale tries to build a bridge between real numbers and integers. Two derivatives in time scale have been introduced and called as delta and nabla derivative. Delta derivative concept is defined as forward direction, and nabla derivative concept is defined as backward direction. Within the scope of this study, we consider the method of obtaining parameters of regression equation of integer values through time scale. Therefore, we implemented least squares method according to derivative definition of time scale and obtained coefficients related to the model. Here, there exist two coefficients originating from forward and backward jump operators relevant to the same model, which are different from each other. Occurrence of such a situation is equal to total number of values of vertical deviation between regression equations and observation values of forward and backward jump operators divided by two. We also estimated coefficients for the model using ordinary least squares method. As a result, we made an introduction to least squares method on time scale. We think that time scale theory would be a new vision in least square especially when assumptions of linear regression are violated.

  3. Predicting naming latencies for action pictures: Dutch norms.

    2014-03-01

    The present study provides Dutch norms for age of acquisition, familiarity, imageability, image agreement, visual complexity, word frequency, and word length (in syllables) for 124 line drawings of actions. Ratings were obtained from 117 Dutch participants. Word frequency was determined on the basis of the SUBTLEX-NL corpus (Keuleers, Brysbaert, & New, Behavior Research Methods, 42, 643-650, 2010). For 104 of the pictures, naming latencies and name agreement were determined in a separate naming experiment with 74 native speakers of Dutch. The Dutch norms closely corresponded to the norms for British English. Multiple regression analysis showed that age of acquisition, imageability, image agreement, visual complexity, and name agreement were significant predictors of naming latencies, whereas word frequency and word length were not. Combined with the results of a principal-component analysis, these findings suggest that variables influencing the processes of conceptual preparation and lexical selection affect latencies more strongly than do variables influencing word-form encoding.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2012n62p127   It was not until the twentieth century, and especially the 1980s, that Dutch Gothic fiction began to flourish. This article gives an overview of the history of the Gothic in Dutch literature, and discusses the explanations given for the absence of a Dutch Gothic tradition. It then examines six Gothic novels from the 1980s in more depth to determine what kind of “cultural work” the Gothic does in late-twentieth century Dutch novels. In those novels, the Gothic is a way of expressing the ambivalences accompanying new societal relations following the 1960s, when constructs of the self in terms of gender and sexuality were reformulated.

    Full Text Available Generally, quality of life of urban population is heavily dependent on social facilities provided within the environment. One of the most important facilities is transportations. Study on transportation mode in an urban area is especially very important because for almost every individual living in a large and densely populated area, mobility is one of the most crucial issues in everyday life. Enhance mobility, faster journey to work and less pollution from petrol-propelled vehicles can increase the quality of life, which in turn lead to a sustainable urban living. The study present transportation mode usage issues faced by community related to quality of life in an urban area. This study identifies several issues of transportation mode in urban areas and its impact on the quality of life. The study areas are Putrajaya, Kuala Lumpur and Bandar Kajang, Selangor. The methodology used in this research is secondary and primary data. The questionnaires for the survey were distributed from May 2008 to Jun 2008. These researches were conducted on 144 respondents for to evaluate their perception of transportation mode correlated to the quality of life. The collected data were then analyzed using “Statistical Packages for the Social Science” (SPSS. The respondents comprise of 61 males and 84 females from the age group of 18 to 57 years. This study identifies the percentage of public transportation mode usage in urban area, such as buses (16.7%, train (ERL, monorail and commuter-6.4%; which is very low compared to owning personal car (45.8% and motorcycle (25.4%.The result shows owning personal car is the highest (45.8% in three study areas and monorail and taxi are the lowest (1.4%.

But “Das Ornament der Masse” is first of all a program for the critical intellectual in the age of mass culture....... Kracauer’s essay may even provide a conceptual basis for critical studies of modern urbanity.

  18. Sustainable urban structures to challenge climate change

    Directory of Open Access Journals (Sweden)

    Emil CREANGA

    2012-07-01

    Full Text Available Public spaces within the city in all their form of different types - streets, boulevards, squares, plazas, market places, green areas - are the backbone of cities. Over the centuries buildings defined the shape and quality of public spaces, valorising them in various ways. The post-modern development of urban form generated a great number of “urban spaces”, where there is no longer correspondence between architectural forms and social and political messages: shopping malls and theme parks, inner public spaces, strip developments etc. Urban sprawl accompanied by loss of agricultural/rural land and its impact on the environment are serious concerns for most cities over Europe. To strike the right balance between inner city regeneration, under-use of urban land in the old abandoned sites and the ecological benefits that accompany the new private business initiatives in suburban areas, is one of the major challenges confronting cities in Europe. The paper will analyze the complex relations between architecture and public space, in an attempt to understand how traditional urban structures, public and green spaces, squares and streets, could provide orientation for quality-oriented regeneration. Case in point is Bucharest - capital city of Romania - where aggressive intervention in the urban structure during the 1980s disrupted the fabric of the city. The investigation is oriented towards fundamental questions such as: how to secure and preserve sites that serve as initial points in upgrading processes, how to balance private investment criteria and the quality interests of the urban communities. The major aim is to provide a support for decision making in restoring the fundamental role of public urban space in shaping urban form and supporting community life.

    Full Text Available Bringing History Home: Postcolonial Immigrants and the Dutch Cultural ArenaThree Dutch-language monographs published in 2008-2009 by Ulbe Bosma, Lizzy van Leeuwen and Gert Oostindie in the context of the interdisciplinary research programme Bringing History Home, present a history of identity politics in relation to ‘postcolonial immigrants’. This term refers to some 500,000 people who since 1945 arrived in the Netherlands from Indonesia and the former Dutch New Guinea, Suriname or the Antillean islands in the Caribbean. Bosma traces the development of postcolonial immigrant organizations. In interaction with government policies, these organizations moved from mere socioeconomic emancipation struggles to mere cultural identity politics. Van Leeuwen takes such cultural identity politics as the starting point for her analysis of Indo-Dutch and Dutch Indies cultural initiatives and the competing interests at stake in the Indies heritage discourse. Oostindie discusses these developments in terms of community development and change within Dutch society at large. He introduces the notion of a ‘postcolonial bonus’. In postcolonial Netherlands, this bonus was available to immigrants on the grounds of a shared colonial past. Today, this bonus is (almost spent. The review discusses the three monographs, as well as the coherence of Bringing History Home as a research programme. Legêne argues, that notwithstanding valuable research outcomes, the very category of postcolonial immigrants does not constitute a convincing category of analysis.

    2009-10-01

    Full Text Available This study focuses on the way in which the Dutch monophthongal vowels are pronounced by Indonesian students. To investigate whether Indonesian students realize the Dutch vowels correctly, especially when they are stressed, I analysed duration and quality of stressed and unstressed Dutch vowels. Measurements were done on the duration and the formant frequencies of the vowels spoken by Indonesian students and by native speakers of Dutch as well. Statistical analysis showed that in general the differences in duration between vowels spoken by the Indonesian students and by the native speakers were not significant. However, the effect of stress on the lengthening of the vowels was stronger for the Indonesian students than for the native speakers. In addition, statistical analysis of the formant frequencies confirmed that the non-native speakers realized the Dutch vowels slightly differently from the Dutch native speakers. The Indonesian students pronounced the stressed vowels more clearly than their unstressed counterparts; yet their vowel diagram is smaller than the vowel diagram of the native speakers.

    Treagus, Susan H.; Lan, Labao

    2003-12-01

    Finite element models of square objects in a contrasting matrix in simple shear show that the objects deform to a variety of shapes. For a range of viscosity contrasts, we catalogue the changing shapes and orientations of objects in progressive simple shear. At moderate simple shear ( γ=1.5), the shapes are virtually indistinguishable from those in equivalent pure shear models with the same bulk strain ( RS=4), examined in a previous study. In theory, differences would be expected, especially for very stiff objects or at very large strain. In all our simple shear models, relatively competent square objects become asymmetric barrel shapes with concave shortened edges, similar to some types of boudin. Incompetent objects develop shapes surprisingly similar to mica fish described in mylonites.

  9. Diagonal loading least squares time delay estimation

    LI Xuan; YAN Shefeng; MA Xiaochuan

    2012-01-01

    Least squares (LS) time delay estimation is a classical and effective method. However, the performance is degraded severely in the scenario of low ratio of signal-noise (SNR) due to the instability of matrix inversing. In order to solve the problem, diagonal loading least squares (DL-LS) is proposed by adding a positive definite matrix to the inverse matrix. Furthermore, the shortcoming of fixed diagonal loading is analyzed from the point of regularization that when the tolerance of low SNR is increased, veracity is decreased. This problem is resolved by reloading. The primary estimation's reciprocal is introduced as diagonal loading and it leads to small diagonal loading at the time of arrival and larger loading at other time. Simulation and pool experiment prove the algorithm has better performance.

  10. Least Squares Moving-Window Spectral Analysis.

    Lee, Young Jong

    2017-01-01

    Least squares regression is proposed as a moving-windows method for analysis of a series of spectra acquired as a function of external perturbation. The least squares moving-window (LSMW) method can be considered an extended form of the Savitzky-Golay differentiation for nonuniform perturbation spacing. LSMW is characterized in terms of moving-window size, perturbation spacing type, and intensity noise. Simulation results from LSMW are compared with results from other numerical differentiation methods, such as single-interval differentiation, autocorrelation moving-window, and perturbation correlation moving-window methods. It is demonstrated that this simple LSMW method can be useful for quantitative analysis of nonuniformly spaced spectral data with high frequency noise.

  11. Dancoff Correction in Square and Hexagonal Lattices

    1966-11-15

    This report presents the results of a series of calculations of Dancoff corrections for square and hexagonal rod lattices. The tables cover a wide range of volume ratios and moderator cross sections. The results were utilized for checking the approximative formula of Sauer and also the modification of Bonalumi to Sauer's formula. The modified formula calculates the Dancoff correction with an accuracy of 0.01 - 0.02 in cases of practical interest. Calculations have also been performed on square lattices with an empty gap surrounding the rods. The results demonstrate the error involved in treating this kind of geometry by means of homogenizing the gap and the moderator. The calculations were made on the Ferranti Mercury computer of AB Atomenergi before it was closed down. Since then FORTRAN routines for Dancoff corrections have been written, and a subroutine DASQHE is included in the report.

    We present a detailed experimental study of the symmetry properties and the momentum space representation of the field distributions of a dielectric square resonator as well as the comparison with a semiclassical model. The experiments have been performed with a flat ceramic microwave resonator. Both the resonance spectra and the field distributions were measured. The momentum space representations of the latter evidenced that the resonant states are each related to a specific classical torus, leading to the regular structure of the spectrum. Furthermore, they allow for a precise determination of the refractive index. Measurements with different arrangements of the emitting and the receiving antennas were performed and their influence on the symmetry properties of the field distributions was investigated in detail, showing that resonances with specific symmetries can be selected purposefully. In addition, the length spectrum deduced from the measured resonance spectra and the trace formula for the dielectric square resonator are discussed in the framework of the semiclassical model.

Its technological challenges and huge cost requires a multinational effort, and Europe has recognised this by putting the SKA on the roadmap of the European Strategy Forum for Research Infrastructures (ESFRI). The Spanish SKA White Book is the result of the coordinated effort of 119 astronomers from 40 different research centers. The book shows the enormous scientific interest of the Spanish astronomical community in the SKA and warrants an optimum scientific exploitation of the SKA by Spanish researchers, if Spain enters the SKA project.

    We study the effect of quantum memory in magic squares game when played in quantum domain. We consider different noisy quantum channels and analyze their influence on the magic squares quantum pseudo-telepathy game. We show that the probability of success can be used to distinguish the quantum channels. It is seen that the mean success probability decreases with increase of quantum noise. Where as the mean success probability increases with increase of quantum memory. It is also seen that the behaviour of amplitude damping and phase damping channels is similar. On the other hand, the behaviour of depolarizing channel is similar to the flipping channels. Therefore, the probability of success of the game can be used to distinguish the quantum channels.

    This article is concerned with natural convective heat transfer from square cylinder mounted on a plane adiabatic base, the cylinders having an exposed cylinder surface according to different horizontal angle. The cylinder receives heat from a radiating heater which results in a buoyant flow. There are many industrial applications, including refrigeration, ventilation and the cooling of electrical components, for which the present study may be applicable

    Let $p$ be a prime number, $p=2^nq+1$, where $q$ is odd. D. Shanks described an algorithm to compute square roots $\\pmod{p}$ which needs $O(\\log q + n^2)$ modular multiplications. In this note we describe two modifications of this algorithm. The first needs only $O(\\log q + n^{3/2})$ modular multiplications, while the second is a parallel algorithm which needs $n$ processors and takes $O(\\log q+n)$ time.

    Considering the coherent nonlinear dynamics in double square well potential we find the example of coexistence of Josephson oscillations with a self-trapping regime. This macroscopic bistability is explained by proving analytically the simultaneous existence of symmetric, antisymmetric and asymmetric stationary solutions of the associated Gross-Pitaevskii equation. The effect is illustrated and confirmed by numerical simulations. This property allows to make suggestions on possible experiments using Bose-Einstein condensates in engineered optical lattices or weakly coupled optical waveguide arrays.

    The thermal mean square displacement (MSD) of hydrogen in proteins and its associated hydration water is measured by neutron scattering experiments and used an indicator of protein function. The observed MSD as currently determined depends on the energy resolution width of the neutron scattering instrument employed. We propose a method for obtaining the intrinsic MSD of H in the proteins, one that is independent of the instrument resolution width. The intrinsic MSD is defined as the infinite ...

    Faraday waves are computed in a 3D container using BLUE, a code based on a hybrid Front-Tracking/Level-set algorithm for Lagrangian tracking of arbitrarily deformable phase interfaces. A new dynamic superlattice pattern is described which consists of a set of square waves arranged in a two-by-two array. The corners of this array are connected by a bridge whose position oscillates in time between the two diagonals.
