Generative feature-based design-by-constraints as a means of integration within the manufacturing industry
The article examines the development of computer aids within manufacturing industry and proposes an alternative approach to the way we design and the designer's role within manufacturing. A feature-based generative design-by-constraints approach is applied, which requires the designer to specify solutions in terms of manufacturing data, which is captured by means of an interactive simulation of machining processes, in which the constraints of equipment, materials and tools are displayed to the designer. The effect of this approach on the integration of all areas within a manufacturing environment is explored, as is the simultaneous design nature of this approach
Advancing automation and robotics technology for the Space Station and for the US economy. Volume 1: Executive overview
In response to Public Law 98-371, dated July 18, 1984, the NASA Advanced Technology Advisory Committee has studied automation and robotics for use in the Space Station. The Executive Overview, Volume 1 presents the major findings of the study and recommends to NASA principles for advancing automation and robotics technologies for the benefit of the Space Station and of the U.S. economy in general. As a result of its study, the Advanced Technology Advisory Committee believes that a key element of technology for the Space Station is extensive use of advanced general-purpose automation and robotics. These systems could provide the United States with important new methods of generating and exploiting space knowledge in commercial enterprises and thereby help preserve U.S. leadership in space
Strategic approach to psychotherapeutic intervention with male institutionalized white adolescents to control absconding
Bibliography: pages 92-98.Using a systems theoretical orientation the objective of this study was to implement a strategic approach for psychotherapeutic intervention with six male institutionalized white adolescents at a local custodial school. It was hypothesized that a strategic approach would control absconding for the duration of the investigation. Surveys of the literature were undertaken to provide the background to psychotherapeutic intervention with adolescents in custodial institutions, strategic psychotherapy and absconding. Absconding was selected as the condition for evaluating the interventions because it was an unambiguous indicator of school-based recidivism, viz., the adolescent was either on the property or he was not. The study was structured as a design-and-demonstrate investigation. Audiotape recordings were made during the sessions. Transcriptions of characteristic procedures and sequences of the strategic approach to psychotherapeutic intervention were presented, inter alia, paradoxes, reframing, metaphors, rituals, the declaration of therapeutic impotence. Evaluation of the interventions was based on follow-up interviews with the subjects and a qualitative analysis of risk of absconding aver the course of the intervention process. At the end of the investigation there was some evidence which suggested that five out of the six subjects were not as committed to absconding as they had claimed to be at the beginning of the study. The design of the study did not allow for the conclusion that the strategic approach for controlling absconding was of greater merit than any other form of intervention or no intervention at all. It was noted, however, that twelve of the eighteen potential subjects for the study indicated that they would abscond as soon as the opportunity arose. Therefore it was recommended that the issue of absconding be given priority in therapy on the admission of each new pupil. Given a strategic approach to addressing the issue of absconding in therapy, attention was drawn to a major aim of this type of intervention, viz., to generate a sense of personal autonomy. Hence a further recommendation was that once a pupil had made a commitment not to abscond, his sense of autonomy would need to be supported by an expeditious transfer to one of the more open hostels
Examining the appropriateness of nonverbal measures of intelligence with deaf and hard-of-hearing children: a critical review of the literature
There are a variety of assessment instruments available today that are widely used to assess the intellectual abilities of children. Specific considerations should be made when using these instruments to assess the deaf and hard-of-hearing population. This critical review of the literature begins with a brief overview of the D-HH population, a general history of intellectual assessment, and assessment considerations that are specific to the D-HH population. Information obtained from available literature regarding the internal consistency of six assessment instruments is presented. The instruments reviewed include the UNIT, the Leiter-R, the WISC-IV, the SB5, the CTONI, and the CAS. The results indicated that all of the measures examined show sufficient reliability and validity when applied to the general population. However, Braden (2005) has suggested that a measurement instrument is appropriate for a particular group when similar reliability and validity values are found for that group as for the general population. Of the measures examined, CTONI reported internal consistency studies with a subgroup of D-HH children in the manual. Additional independent research on the internal consistency of the UNIT and the WISC-IV is available. The literature review suggests that there are several factors that can influence test results when working with the D-HH population that have not been examined through independent research to date. Areas of interest for future research are presented
Where design meets construction: a review of bending active structures
Considerable gaps and discontinuities can arise between the design and the construction of bending
active structures. Computational techniques are increasingly widespread in the conceptual design stage
with a high degree of precision; even though, they are less commonly used in the manufacturing and
construction process, where they exhibit higher inaccuracies. This discrepancy can either introduce
redundant structural elements or develop highly demanding construction methods.
This paper presents a literature review over a selection of recently built bending active structures,
focusing on how information flows from conceptual design to manufacturing, construction and
operational life. Selected projects, organized in a multi-criteria matrix, are analyzed according to their
generative approach, structural efficiency, manufacturing processes, installation kits and construction
methods. The critical analysis of case studies is intended to investigate how construction is influenced
by fabrication techniques, focusing on the role of advanced design and manufacturing, as well as the
artisanal workforce.
The work presented offers the opportunity to explore how and when creativity and innovation are
generated in the information flow between the different actors (i.e. architects, engineers,
manufacturers, builders) involved in the project development of bending active structures. It also
inspires speculations upon potential applications of flexible construction responding to multiple uses
over time

Hybrid System of Distributed Automation
One of the most important tendencies in the development of the
industrial automation is the application of intelligent control systems
within factories, which focuses heavily on networked architectures.
Following this line of thinking, the goal of this dissertation resumes itself
in the implementation of a distributed system that controls two physical
processes, where the system components not only trade information
between each other, but also have that same information be accessible
remotely and within HMI equipment.
The controllers were conceptualized to offer different functional modes
with high customization available.
This system also takes resource of an OPC server, so it allows, not only
the communication between different manufacturer PLC controllers but
also the connection with remotes clients
The implemented remote clients hold the intent of demonstrating the
versatility of this architecture and are, namely, an operational historian
that registers information and a data viewer, which allows the use of more
advanced methods of monitoring

Developing a Methodology for Investigating the Design of Award Winning Industrial Architecture
This paper reports on research currently being conducted to investigate the methodological structure of the design of industrial buildings. A comparative analysis of a selection of exemplary industrial buildings is being used to investigate the relationship between the design process and the quality of the design proposal as realised. The evaluation of any realised design remains as tangible evidence of the success or otherwise of the design process that generated it. Therefore, to develop a conceptual framework linking design methods and building quality should contribute to a greater understanding of how the designer's interpretation of a design problem influences the structure of the design process. The effectiveness of the design process in producingindustrial buildings of high quality can also be evaluated
