Integrated methods and scenario development for urban groundwater management and protection during tunnel road construction: a case study of urban hydrogeology in the city of Basel, Switzerland

In the northwestern area of Basel, Switzerland, a tunnel highway connects the French highway A35 (Mulhouse-Basel) with the Swiss A2 (Basel-Gotthard-Milano). The subsurface highway construction was associated with significant impacts on the urban groundwater system. Parts of this area were formerly contaminated by industrial wastes, and groundwater resources are extensively used by industry. During some construction phases, considerable groundwater drawdown was necessary, leading to major changes in the groundwater flow regime. Sufficient groundwater supply for industrial users and possible groundwater pollution due to interactions with contaminated areas had to be taken into account. A groundwater management system is presented, comprising extensive groundwater monitoring, high-resolution numerical groundwater modeling, and the development and evaluation of different scenarios. This integrated approach facilitated the evaluation of the sum of impacts, and their interaction in time and space with changing hydrological boundary conditions. For all project phases, changes of the groundwater system had to be evaluated in terms of the various goals and requirements. Although the results of this study are case-specific, the overall conceptual approach and methodologies applied may be directly transferred to other urban area

Is the CERN recommended SCADA useable for the ST division?

Supervisory Control and Data Acquisition (SCADA) systems are widely used at CERN and in industrial control environments. In order to limit the costs of purchase, maintenance and support, a recommendation for one SCADA system is in preparation by the SCADA working group. This SCADA system should be used for all CERN in-house developed applications as they exist today e.g. in the Technical Control Room (TCR). This presentation will show the actual environment for the control and monitoring of the technical infrastructure at CERN and the needs for the future LHC infrastructure monitoring. The presentation will cover the control activities of all ST groups represented in the ST Control System WG. A possible solution for the integration of the technical infrastructure data into a SCADA system and a solution for the data exchange with the accelerators and the experiments will be presented. This includes a short term planning for the evaluation period as well as the long-term strategy on how to implement the chosen solution

TCR remote monitoring for the LHC technical infrastructure

The remote monitoring of the LHC technical infrastructure will mainly be done in CERN’s Technical Control Room (TCR). The technical infrastrucure consists of specialised equipment from different groups and divisions, mainly cooling and ventilation and electrical equipment. The responsibility for the definition, operation and maintenance of the equipment is covered by the relevant equipment group. However the monitoring and alerting for action in case of equipment failure is initiated by the TCR and is based on alarms that are sent by the equipment. This implies the correct integration of the equipment and the establishment of rules to follow during the commissioning and start-up of the equipment in order to ensure proper operation. This paper shows the integration possibilities and the different tasks and steps to follow by the different parties for smooth equipment integration and avoiding organizational problems

CERN LHC Technical Infrastructure Monitoring (TIM)

The CERN Large Hadron Collider (LHC) will start to deliver particles to its experiments in the year 2005. However, all the primary services such as electricity, cooling, ventilation, safety systems and others such as vacuum and cryogenics will be commissioned gradually between 2001 and 2005. This technical infrastructure will be controlled using industrial control systems, which have either already been purchased from specialized companies or are currently being put together for tender. This paper discusses the overall architecture and interfaces that will be used by the CERN Technical Control Room (TCR) to monitor the technical services at CERN and those of the LHC and its experiments. The issue of coherently integrating existing and future control systems over a period of five years with constantly evolving technology is addressed. The paper also summarizes the functionality of all the tools needed by the control room such as alarm reporting, data logging systems, man machine interfaces and the console manager. Particular attention is paid to networking aspects, so that reliable and timely transmission of data can be assured. A pyramidal layered component architecture is compared with a complete SCADA solution

The first year of the ST Operation Committee: is there a future ?

The main objective of the ST Operation Committee (STOC) was to develop a proactive and homogeneous service of operation that satisfies the needs of the service users. Furthermore, the role of the Technical Control Room (TCR) should have been developed to a unique and competent entry point for ST operation by bringing the operation teams closer together on a daily basis. Have these objectives been achieved and to what extend? Is there a future for this committee and what could it look like? What are the implications of the first year of work on ST operation as a whole? This paper answers these questions and gives recommendations how to make best use of the STOC for the ST partners and ST, respectively

Groundwater, geothermal modelling and monitoring at city-scale : reviewing European practice and knowledge exchange : TU1206 COST sub-urban WG2 report

The need for cities to make more effective use of the subsurface on which they stand, is increasingly being recognised in Europe and further afield to be essential for future cities to be sustainable and more resilient [1,2]. However, city planning worldwide remains largely 2D, with very few cities having any substantial subsurface planning or Masterplans – the cities of Helsinki, Montreal, Singapore being rare exceptions [3,4]. The consequences of inadequate consideration and planning of the subsurface are far-reaching, in economic, environmental and social terms. Across Europe, poor understanding of ground conditions is recognised as the largest single cause of construction project delay and overspends [5]. Management of urban groundwater and shallow geothermal energy resources is becoming increasingly important as cities are increasingly looking to use these resources to meet current and future energy and heating and water needs. Whilst these are, alongside potential underground building space, the two most important resources for future cities, the monitoring and regulation of these resource is widely variable across Europe. For subsurface opportunities such as groundwater and geothermal energy to be realised and utilised to greatest effect to support growing city populations and infrastructure, city planners must be both aware of, and have some understanding of the resources, available data and research, and both the opportunities and risks which the resources provide to city development [6,7]. To supply this understanding to city municipalities and others, geological surveys must have robust datasets of groundwater and geothermal resources at city-scale, and the relevant knowledge and understanding from these data must be made accessible to inform subsurface planning in appropriate datasets relevant to different scale of interest in different planning stages. What density and frequency of data are required for a robust understanding of a city’s groundwater and geothermal resources will be different in different cities, according to the complexity of the resources, and the intensity of subsurface use and demands on the resources. Indeed, no one design of city-scale monitoring or modelling of ground-water and -heat resources is appropriate for all cities, or for all monitoring objectives. However, the guiding principles of good practice for developing robust city-scale monitoring, and datasets are widely applicable, as are the key principles for ensuring these data inform city planning processes. This report provides an initial review of existing examples of current practices in Europe with respect to groundwater and geothermal monitoring and modelling, as a resource for other cities to learn from and build upon. The report also provides an overview of some of the different practices used for communicating groundwater and geothermal energy data and knowledge to inform urban planning and managemen

Učinkovitost u zadacima fine motorike i prostornih odnosa tijekom menstrualnog ciklusa

Various studies have shown fl uctuations in task performance during the menstrual cycle. The aim of this study was to see the effects of the menstrual cycle on performing fi ne motor and spatial tasks of different level of complexity in twenty students aged 18 to 21 years, with regular menstrual cycle (28 to 30 days). The students performed O’Connor Finger Dexterity Test and mental rotation test during the menstrual, late follicular, and midluteal phase. Before the tests were performed, we administered Spielberger’s State-Trait Anxiety Inventory for each phase. After the tasks were completed, the subjects ranked their diffi culty on Borg’s scale. The results showed the best performance in both tests in the midluteal phase (with sex hormones at their peak). The anxiety level and task diffi culty ranking were the highest in the menstrual phase, when the hormone levels were the lowest.Različita su istraživanja pokazala promjene učinkovitosti tijekom menstrualnog ciklusa. U zadacima u kojima su uspješnije žene, najveća učinkovitost događa se tijekom kasne folikularne ili srednje lutealne faze. U zadacima u kojima su pak uspješniji muškarci najveća je učinkovitost nađena u menstrualnoj fazi. Na osnovi uporabe zadataka fi ne motorike i prostornih zadataka različitih razina kompleksnosti, cilj ovog istraživanja bio je ispitati utjecaj menstrualnog ciklusa na kognitivne funkcije. U istraživanju je sudjelovalo dvadeset ispitanica, dobi od 18 do 21 godinu, s redovitim menstrualnim ciklusima (28 do 30 dana). Ispitanice su izvodile O’Connorov deksterimetar i zadatke mentalne rotacije tijekom menstrualne, kasne folikularne i srednje lutealne faze. Prije izvođenja zadataka, u svakoj fazi ciklusa primijenjen je Spielbergerov upitnik stanja anksioznosti. Nakon izvođenja zadataka, ispitanice su procjenjivale njihovu težinu na Borgovoj skali. Rezultati su pokazali najbolju učinkovitost u oba zadatka u fazi visokih razina spolnih hormona (srednja lutealna faza). Stanje anksioznosti i procijenjene težine zadataka bili su najviši u menstrualnoj fazi, kada su razine spolnih hormona najniže

The application of the repertory grid in forensic practice

The purpose of this paper is to demonstrate the utility of the repertory grid method with forensic populations. Three case studies are presented, each using an adapted variation of the repertory grid method with a different forensic clients: an individual maintaining their innocence, an individual convicted of sexual offenses, and an individual convicted of stalking. An analysis of the repertory grid findings is presented for each case study, including a Principal Component Analysis and a Self-Identity Plot. This analysis of subjective meaning and idiosyncratic belief systems proves invaluable ordinarily, but particularly when working with populations who present as suspicious and guarded in research or clinical settings. Relationship and offending-related psychological vulnerabilities are explored, with small psychological changes documented and the use of the repertory grid approach as a clinical tool is highlighted. The findings provide a significant contribution to the field of forensic practice, by demonstrating the utility of the repertory grid method when working with forensic populations. This may, in turn, contribute to researchers’ and practitioners’ consideration of its use within future forensic practice
