Resolution studies with the DATURA beam telescope

Detailed studies of the resolution of a EUDET-type beam telescope are carried out using the DATURA beam telescope as an example. The EUDET-type beam telescopes make use of CMOS MIMOSA 26 pixel detectors for particle tracking allowing for precise characterisation of particle sensing devices. A profound understanding of the performance of the beam telescope as a whole is obtained by a detailed characterisation of the sensors themselves. The differential intrinsic resolution as measured in a MIMOSA 26 sensor is extracted using an iterative pull method and various quantities that depend on the size of the cluster are discussed: the residual distribution, the intra-pixel residual-width distribution and the intra-pixel density distribution of track incident positions

Development and simulations of Enhanced Lateral Drift Sensors

We present the concept of a new type of silicon tracking sensor called Enhanced Lateral Drift (ELAD) sensor. In ELAD sensors the spatial resolution of the impact position of ionising particles is improved by a dedicated charge sharing mechanism, which is achieved by a non-homogeneous electric field in the lateral direction in the sensor bulk. The non-homogeneous electric field is created by buried doping implants with a higher concentration with respect to the background concentration of the bulk. The resulting position-dependent charge sharing allows for an improved interpolation of the impact position. TCAD-based electric field simulations for 2D and 3D geometries as well as transient simulations with a traversing particle for the 2D geometry have been carried out. The electric field profiles have further been optimised for position resolution. The simulations show a strong dependence of the charge sharing mechanism on the buried implant concentration. Optimal values for the buried implant concentration allow for nearly linear charge sharing between two readout electrodes as a function of the impact position. Additionally, the foreseen production technique combining silicon epitaxy and ion beam implantation is outlined.Comment: 9$^{\text{th}}$ International Workshop on Semiconductor Pixel Detectors for Particles and Imaging, DESY 19-08

Suburban Infill to Redevelop Suburbia - Retrofitting Post-Suburban Business Locations in the Zürich Metropolitan Area as a Component of Growth Management

Regional growth management has become a significant component of sustainable urban land development in many European metropolitan areas. Particularly in rapidly growing metropolitan regions, increasing population and job numbers require strategic planning management, but there is little knowledge about which planning instruments influence or direct these processes most effectively. Based on an analysis of spatial development in the Zürich metropolitan region, particularly in suburban areas, over the past several decades, this article examines the opportunities for the infill, revitalization and retrofitting of suburban business locations as key elements of growth management. In doing so, this article focuses on one central question: To what extent does (cantonal) regional planning and its specific instruments (cantonal structure plan) influence and control the spatial development and urban design quality in the retrofitting of suburban locations? The Glattal region was chosen as a case study as it experienced a significant change in terms of its urban structure during the last 10–15 years. In this context, suburban service locations were examined and analysed in depth using two case studies. The Hochbord area in Dübendorf and the Glattpark area in Opfikon demonstrate the conversion of formerly mono-functional areas (Hochbord) to mixed-use neighbourhoods and the development of new mixed-use locations (Glattpark). The article demonstrates how the suburban office stock transformed to strategic spots for mixed-use in both locations and explores how the retrofitting process could be directed at the cantonal level. In this context, spatial planning instruments at the regional level, such as the cantonal structure plan, seem to play a significant role in the transformation of the urban periphery

Mobilstationen – Bausteine für eine zukunftsfähige Mobilität in der Stadt

For making our cities and regions more attractive, clean, competitive and liveable, solutions for an intelligent urban mobility are necessary. Urban transportation and traffic developments all over the world show the huge demand for solutions in this field. Future urban mobility is based on an intermodal traffic system, which allows people flexible and multimodal travelling within the city. Therefore the capacity of public transportation as the backbone of urban traffic systems has to be extended for individual traffic modes. The integration of the motorised individual traffic and cycling – both also provided as sharing offers – will be one important factor. Not only technological innovations extend the opportunities of travel mode choice. A key factor is the focus on the user and its lifestyle-related mobility preferences, since functionality, sensible integration in urban fabric accompanied by a user-centred design and the easy access to mobility offerings are two important aspects in terms of usability. Developing mobility stations at strategically relevant traffic nodes – including at least two forms of public transport – is beside others one of the measures recommended by the International Association of Public Transport (UITP 2012: 22). Due to its function and visibility within the urban space mobility stations could serve as the physical expression of future mobility. The central idea of a mobility station is the structural and spatial connection of functionality and design. As an important interface of public transportation and individual traffic modes the station needs to be organised as good as possible. Thus the size respectively the quality and quantity of features and offerings of each station depend on its location within the city. A basic requirement of mobility stations is the connection between different modes of transport including the availability of environmental-friendly forms of mobility. A sensible integration in the urban context along with a recognizable design of mobility station areas is the basis for developing an attractive urban space of high quality, which also serves as meeting point for people living in the neighbourhood and as a place of arriving, departure or change. Therefore mobility stations can in a second dimension serve as Bausteine to improve urban quality by reshaping the former traffic space

Strategy implementation practices and processes in defence evaluation and research institutes in South Africa

The purpose of this study was to explore the practices and processes executed by middle managers as practitioners during the implementation of strategy. In order to do that, this study investigated the problem of strategy implementation, analysed existing literature, identified the gaps, and explored the roles of middle managers in terms of strategy practices and processes, specifically in the South African Defence Evaluation and Research Institutes (DERI) context. Resources, time and effort are applied to formulating strategy but less of these to the execution of the strategy which includes the emotions, motivations and actions that are intangible during the implementation of strategy. The study therefore attempts to answer the following research question: What practices and processes are employed in strategy implementation in DERIs in South Africa? The literature study was undertaken with the objective of mapping the research problem and to highlight, through critical discussion, the latest work done on the subject of this study. The gap in relation to research work was identified and the contribution is clear that not much work has been done in this environment. Research is a systematic process where information on a specific topic is gathered in order to increase understanding of that phenomenon. A qualitative study was performed and data was obtained from several institutes through interviews, documents and questionnaires in order to build a rich database that could be analysed for the required output. Engagement with the first level of management as well as the next level management teams ensured that a representative population group was used during this study. The data was organised, categorised, interpreted, identified, synthesised and generalised. The quotations identified from the text were coded through inductive coding and grouped into categories until a logical theme, category and concept was formed. The objective of this research was to investigate, identify and understand what the strategy practices and processes are that make highly technical and scientific institutes execute strategies successfully. The study provided insight into and clarity on the complexity of the strategy implementation process as executed by middle managers, particularly in the South African context. The link was explored between formulation and implementation as applied by middle managers as practitioners and the practices and processes in use were identified. It was demonstrated that the outcome of this research is applicable to the research problem and also provides an understanding of the phenomenon, namely strategy practices and processes in use at the Defence Evaluation and Research Institutes. It can therefore be concluded that the research objective was achieved.Business ManagementD.B.L
