Understanding cognitive heterogeneity in psychosis and high risk individuals
De ernst van cognitieve problemen kan sterk verschillen tussen patiënten met een psychotische stoornis onderling. Julia Meijer keek of deze verschillen te verklaren zijn uit drugsgebruik - frequent gebruik nu en in het verleden was namelijk geassocieerd met meer problemen in verbaal leren en werkgeheugen. Patiënten met een psychotische stoornis ervaren vaak problemen bij het verwerken van informatie. Dat heeft een negatieve invloed op hun sociaal en beroepsmatig functioneren. De ernst van cognitieve problemen kan sterk verschillen tussen patiënten onderling. Julia Meijer keek of deze verschillen te verklaren zijn uit drugsgebruik - frequent gebruik nu en in het verleden was namelijk geassocieerd met meer problemen in verbaal leren en werkgeheugen. Er bleek geen verband met obsessief-compulsieve symptomen (angst- en dwangstoornissen). Patiënten met een psychose zijn minder goed in geuridentificatie. Wellicht kan dat in de toekomst gebruikt worden als marker voor het risico op het ontwikkelen van een psychose
Graph-based identification of critical elements in urban water infrastructure
The purpose of this thesis was to develop and demonstrate methods for determining the criticality of elements in networks. The impact failures could have on the network performance was its primary focus. A second objective was to determine whether the developed method could be applied successfully based on network characteristics. To achieve these goals, research was conducted on factors that influence the criticality of an element, on the possibilities of applying simplified hydrodynamic processes in the determination of criticality and on the contribution of different model components to the functioning of water network models
Accelerated norm-optimal iterative learning control
This paper proposes a novel technique for accelerating the convergence of the previously published norm-optimal iterative learning control (NOILC) methodology. The basis of the results is a formal proof of an observation made by the first author, namely that the NOILC algorithm is equivalent to a successive projection algorithm between linear varieties in a suitable product Hilbert space. This leads to two proposed accelerated algorithms together with well-defined convergence properties. The results show that the proposed accelerated algorithms are capable of ensuring monotonic error norm reductions and can outperform NOILC by more rapid reductions in error norm from iteration to iteration. In particular, examples indicate that the approach can improve the performance of NOILC for the problematic case of non-minimum phase systems. Realisation of the algorithms is discussed and numerical simulations are provided for comparative purposes and to demonstrate the numerical performance and effectiveness of the proposed methods

The Life and Work of D.H. Hyers, 1913-1997
The following is a sketch of the life and work of Donald Holmes Hyers, Professor Emeritus from the University of Southern California. The theorem put forth by Hyers in 1941 concerning linear functional equations has gained a great deal of interest over the past two decades. Hundreds of articles have been written citing his works, many of which have furthered the theorem. This paper contains a brief description of Hyers’ theorem, a biographical essay and an extensive bibliography of Hyers’ work and works citing the Hyers theorem or the D.H. Hyers–S.M. Ulam–Th.M. Rassias theorem or related subjects of almost the last three decades. The author of this paper is the grandson of D.H. Hyers
Hidden Danger: Mapping consequences of underground water infrastructure failure to guide asset management
Continuous functioning of sewer systems and water distribution networks is crucial for liveability, public health and economic prosperity in urban areas. Progressive deterioration of these underground water infrastructures leads to an increased probability of failure. Maintenance is needed to ensure a desired level of functioning. For municipalities and drinking water companies as asset owners, the trend is to develop risk-based asset management. A risk-based asset management strategy links the likelihood of failure with the consequences. Hence, knowledge is needed on the condition of the underground water infrastructure and the consequences in case of failure. Within this strategy, a risk assessment should be performed to prioritise the maintenance and renewal of underground water infrastructure. Based on their criticality, resources can be applied appropriately. The more critical a conduit segment, the more important it is to perform maintenance. To contribute to risk-based asset management, this study investigates the consequences of failure in sewer systems and water distribution networks. In this research, a methodology is developed for mapping consequences of underground water infrastructure failure to guide asset management. Including the consequences of underground water infrastructure failure in the risk determination may lead to a different prioritisation of maintenance activities. Three failure mechanisms are considered: structural sewer failure, hydraulic sewer failure and water distribution network failure. Structural sewer failure leads to partial or complete loss of the load-carrying capacity, whereas hydraulic sewer failure occurs when a system does not meet serviceability requirements for system performance. For water distribution networks, it is assumed that hydraulic failure (caused by overpressure) and structural failure occur simultaneously. Hence, no distinction is made between failure mechanisms in water distribution networks. Using a screening method, the consequences of underground water infrastructure failure are mapped. The consequences of failure are expressed as the affected area and the characteristics of the built environment. The affected area consists of the sinkhole area and the flood zone. The characteristics of the built environment are displayed by means of consequence categories. Within this study, five different consequence categories are taken into account, using hydraulic modelling and (open) classified data. The consequence categories are: 1) Damage to buildings 2) Traffic obstruction 3) Impact on human health 4) Costs of conduit reconstruction 5) Drinking water supply outage. A flat, typical Dutch study area in Tuindorp (Utrecht) is used to test the methodology. For these five consequence categories, findings are illustrated and compared with the results of the hydraulic network functioning according to the Graph Theory method (GTM). This GTM determines the effects of failure of individual conduits on the functioning of a system as a whole, based on a simplified network structure using links and nodes. Results of the analyses show a positive relation between the individual consequences in case of hydraulic sewer failure. For example, critical conduits in the category `damage to buildings', are critical for `impact on human health' as well. Besides, there is a positive relation between the consequence categories and the hydraulic network functioning. Conduits with large diameters are stated as critical for both methods, yet dead-end segments are only critical for hydraulic network functioning. Contradictory, individual consequences are uncorrelated for structural sewer failure and water distribution network failure. The consequences are independent and can not be linked. Besides, there is no relation between the hydraulic network functioning and the individual consequences of structural sewer failure and water distribution network failure.Water Managemen

Environmental (waste) compliance control systems for UK SMEs
While the ‘environment’ is often perceived as a heavily regulated area of business, in reality, directly-regulated businesses represent a small proportion of the business community. This study aimed to evaluate and outline potential improvements to compliance controls for small and medium-sized enterprises (SMEs), particularly those involved in the waste sector. Forty-four SMEs from England were interviewed/audited between April-September 2008. Using a UK-based system as a case-in-point, the Environment Agency’s (EA) Operational Risk Appraisal (‘Opra’)/Compliance Assessment Report (CAR) system was analysed. Environmental compliance performance indicators and an initial assessment methodology for SMEs were developed. The study showed:• Compliance with permitting legislation was poor in many areas.• Regulatory authorities are either unable/failing to implement their enforcement policies or unable/failing to identify non-compliances due to the infrequency or limited nature of their inspections.• Improvements are needed to the EA Opra/CAR system – control measures are not fully taken into account when calculating risk.Recommendations to improve SME compliance controls include using internationally applicable general and specific compliance and non-compliance performance indicators, re-designing the Opra system and using an initial assessment methodology based on understanding the hazardousness of SME categories, compliance levels and operator competency.<br/
The Importance Of Sex In Marriage Reflected In D.H. Lawrence’s Lady Chatterley’s Lover Novel (1928): A Psychoanalytic Perspective
This study is about the importance of sex in marriage in Lady Chatterley’s Lover. The objectives of the study are conducted to identify the indicators of the need for sex of the major character, to describe the major character attempt to meet the need, and to reveal the underlying reason of why the major character did viewed from the psychoanalytic perspective. The object of the study is Lady Chatterley’s Lover by D.H. Lawrence. It used psychoanalytic perspective. This research is a descriptive qualitative research. The type of data in this study is a text that consists of words, phrases and sentences. There are two data sources in this study. The primary data source is Lady
Chatterley’s Lover by D.H. Lawrence. The secondary data source consists of the other data, which have a relationship with the study, such as some biography of
the author, and other relevant information. The result of the study shows the following conclusions. First, based on the structural analysis the author wants to deliver a message that the meeting of sexual need is important in marriage. Second, based on the psychoanalytic perspective, it clear that in this novel D.H. Lawrence describes psychological phenomena in which one is seeking for the sexual satisfaction from a person other than one‟s spouse
A topological characterisation of looped drainage networks
Hydrodynamic models are used to analyse water networks (water distribution, drainage, surface water, district heating, etc.). The non-linear nature of water flows necessitates the use of iterative solution methods in hydraulic modelling. This requires a relatively large computational effort. To reduce this effort, networks, network forcing and/or the flow in networks are often simplified and analysed using the Graph Theory. The simplification options depend on the network characteristics. There are many topological features to describe Graph-based networks. In this paper, these characteristics are summarised, applied on 7 urban drainage networks and discussed. As the topological features do not describe the networks in a uniform manner, a new type of topological characterisation of looped drainage networks (Network Linearisation Parameter, NLP) is proposed based on linearized hydraulics and bottlenecks identified in paths to outfalls.Sanitary Engineerin
DELTA.M: A tool for metropolitan designing systems
This research deals with the development of a tool to enable designers, decision-makers and citizens to jointly shape the physical environments they inhabit, through interaction and communication via electronic networks. The designing of physical environment becomes the collective responsibility of all interested societal actors, who together form a "designing system". This research defines a 'designing system' as a temporary alliance of people responsible for decisions about the spatial development of an area, consisting of public and private investors, and citizens. This research involved the integration of theoretical knowledge, empirical knowledge and information communication technologies (ICT) in order to develop a tool, the decision support system called "Delta M."Architectur
