An intelligent inspection and survey robot. Volume 1
ARIES {number_sign}1 (Autonomous Robotic Inspection Experimental System), has been developed for the Department of Energy to survey and inspect drums containing low-level radioactive waste stored in warehouses at DOE facilities. The drums are typically stacked four high and arranged in rows with three-foot aisle widths. The robot will navigate through the aisles and perform an inspection operation, typically performed by a human operator, making decisions about the condition of the drums and maintaining a database of pertinent information about each drum. A new version of the Cybermotion series of mobile robots is the base mobile vehicle for ARIES. The new Model K3A consists of an improved and enhanced mobile platform and a new turret that will permit turning around in a three-foot aisle. Advanced sonar and lidar systems were added to improve navigation in the narrow drum aisles. Onboard computer enhancements include a VMEbus computer system running the VxWorks real-time operating system. A graphical offboard supervisory UNIX workstation is used for high-level planning, control, monitoring, and reporting. A camera positioning system (CPS) includes primitive instructions for the robot to use in referencing and positioning the payload. The CPS retracts to a more compact position when traveling in the open warehouse. During inspection, the CPS extends up to deploy inspection packages at different heights on the four-drum stacks of 55-, 85-, and 110-gallon drums. The vision inspection module performs a visual inspection of the waste drums. This system will locate and identify each drum, locate any unique visual features, characterize relevant surface features of interest and update a data-base containing the inspection data
A theoretical and practical investigation of tools and techniques for the structuring of data and for modelling its behaviour
This thesis is about data and behaviour modelling for information system development. It has been sponsored at different times by two specialist consultancies: CACI Inc International and James Martin Associates.
Initially I found problem areas in the field of system development by interviewing practitioners and by consultancy. These initial problem areas were whittled down to: action modelling, entity model clustering and a diagrammer.
Action modelling is the modelling of detailed data behaviour using the same structuring concepts as data modelling. It was developed because of a lack of such analysis in systems development.
Entity model clustering is about aggregating the entity types in a large entity model to abstract the essential meaning and to identify the most fundamental entity types. It was developed because of a need to summarise large entity relationship models for usability and comprehension. It has been used widely and has many benefits.
A parallelism between data and activity modelling was developed as a result of the research into action modelling and entity model clustering. It needed the concepts derived from the other two areas to finally complete the theory, summarised as: every data modelling concept and structure has an exact equivalent in activity modelling and vice-versa. This theory gives a wholeness and completeness to modelling data and activity.
A diagrammer was produced for the automatic production and manipulation of entity relationship diagrams from a base description. These diagrams are the basic tool of the data modeller; automating them saves time and potentially raises their accuracy.
The main research problem was that few companies were willing to be guinea pigs, so most of the research was developed by thought 'games'. Most areas have been published in refereed publications as this was seen as the best way of establishing their academic credibility. All areas have been incorporated into or had an impact on James Martin Associates and their methodology Information Engineering, which provides a framework for
coordinating the research areas.
This research can best be techniques for improving summarised as the systems an attempt to find analysis process

A data-centric framework to perform end-of-life chemical flow analysis
[ES] Los productos qu铆micos est谩n presentes en actividades comerciales,
industriales y de consumo en todo el mercado mundial. El n煤mero de
sustancias qu铆micas que circulan por el mercado no deja de crecer, lo que
puede dificultar a los organismos gubernamentales la gesti贸n del riesgo
qu铆mico mediante la imposici贸n de restricciones reglamentarias y a las
empresas la selecci贸n de qu铆micos con perfiles m谩s seguros antes de lanzar
los productos al mercado o utilizarlos en los procesos de fabricaci贸n.
La identificaci贸n de los escenarios de exposici贸n a las sustancias qu铆micas
y de las cantidades que pueden liberarse en el medio ambiente son tareas
importantes para la evaluaci贸n del riesgo. Sin embargo, para estas tareas
hay que recopilar datos exhaustivos, lo que las convierte en una tarea larga
y dif铆cil. Adem谩s, estas tareas son a煤n m谩s dif铆ciles en la fase de fin de
vida (EoL, por sus siglas en ingl茅s) debido a la incertidumbre epist茅mica
sobre las v铆as exactas que siguen las sustancias qu铆micas a trav茅s de la
cadena de gesti贸n EoL.
Esta tesis pretende avanzar en el desarrollo de un marco hol铆stico que
permita realizar r谩pidamente el an谩lisis del flujo qu铆mico (CFA, por sus
siglas en ingl茅s) para la estimaci贸n y asignaci贸n de emisiones y la identificaci贸n
de escenarios de exposici贸n en la fase de fin de vida. Se propone un
enfoque centrado en los datos, en el que la ingenier铆a de datos desempe帽a
un papel crucial en la recopilaci贸n, transformaci贸n, armonizaci贸n y almacenamiento
de datos procedentes de sistemas de bases de datos de acceso
p煤blico, reglamentarios y aislados. En primer lugar, esta tesis explora el uso
de los datos reglamentarios de Estados Unidos para rastrear las sustancias
qu铆micas contenidas en los flujos de EoL transferidos por las instalaciones
industriales estadounidenses a lugares externos para su posterior gesti贸n.
En segundo lugar, este trabajo se adentra en las instalaciones industriales
para identificar las posibles tecnolog铆as de reducci贸n de la contaminaci贸n
aplicadas por las industrias, mejorando as铆 el CFA y la asignaci贸n de flujos.
En tercer lugar, los resultados de los dos pasos anteriores se conectan y
ampl铆an para describir el comportamiento de la cadena de gesti贸n de EoL
y el bucle de reciclaje, permitiendonos la identificaci贸n de transferencias
de flujo entre industrias y los posibles escenarios de exposici贸n posteriores
al reciclaje. En cuarto lugar, se hace un esfuerzo por ampliar el marco m谩s
all谩 de la informaci贸n estadounidense e incorporar datos de inventario de
otros pa铆ses y a帽os. Por 煤ltimo, los datos obtenidos en el cuarto paso se
utilizan para explorar el desarrollo de modelos basados en datos capaces de identificar posibles escenarios de exposici贸n a la EoL y de incorporarlos
al marco de comprensi贸n de la cadena de gesti贸n de EoL.
Estos estudios est谩n destinados a contribuir al desarrollo e implementaci贸n
de una metodolog铆a para la detecci贸n r谩pida de posibles escenarios
de exposici贸n qu铆mica de EoL y estimaciones de emisiones, as铆 como para
abordar los desaf铆os en la realizaci贸n de la evaluaci贸n de riesgos qu铆micos
para la toma de decisiones regulatorias y la selecci贸n de productos
qu铆micos de perfil m谩s seguro basado en el pensamiento del ciclo de vida.
[EN] Chemicals are involved in commercial, consumer, and industrial activities
across the world marketplace. The number of chemicals circulating
in the market keeps growing, which can make it difficult for government
agencies to manage chemical risk by imposing regulatory restrictions
and for businesses to select chemical candidates with safer profiles before
launching products into the market or using them in manufacturing
processes.
The identification of chemical exposure scenarios and the quantities of
chemicals that may be released into the environment are important tasks
for risk evaluation. Nonetheless, comprehensive data must be collected for
these tasks, making them time-consuming and challenging. In addition,
these tasks are even more difficult at the end-of-life (EoL) stage due to
the epistemic uncertainty about the exact pathways taken by chemicals
through the EoL management chain.
This thesis aims at moving forward to develop a holistic framework
to rapidly perform chemical flow analysis (CFA) for release estimations
and allocation and exposure scenario identification at the EoL stage. A
data-centric approach is proposed where data engineering plays a crucial
role in collecting, transforming, harmonizing, and storing data from
publicly-accessible, regulatory, and siloed database systems. First, this
thesis explored the use of U.S. regulatory data to track chemicals contained
in EoL flows transferred by U.S. industrial facilities to off-site locations for
further EoL management. Second, this work moves into industrial facilities
to identify the potential pollution abatement technologies implemented
by industries, thereby improving the CFA and flow allocation. Third, the
results of the above two steps are connected and extended to describe the
behavior of the EoL management chain and recycling loop, allowing us to
identify the inter-industry flow transfers and potential post-recycling exposure
scenarios. Fourth, an effort is made to extend the framework beyond
U.S. information and incorporate inventory data from other countries and
years. Finally, the data obtained in the fourth step is used to explore the
development of data-driven models able to identify potential EoL exposure
scenarios and be incorporated into the framework for understanding the
EoL management chain.
These studies are intended to contribute to the development and implementation
of a methodology for the rapid screening of potential EoL
chemical exposure scenarios and release estimates, as well as to address the challenges in performing chemical risk evaluation for regulatory decisionmaking
and selecting safer profile chemicals based on life cycle thinking
