The Model of the IT Impact Treated as Feedback in a Production Environment Based on a Cybernetic Model
Cornelia NOVAC-UDUDEC,Daniela Ancuta SARPE
Risk in Contemporary Economy , 2011,
Abstract: This paper presents an approach on the assessment of the impact that Information Technology has in an based- knowledge economy. In order to achieve this goal, we proposed the use of feedback model from the production environment, considered as a cybernetic system. The impact of the IT is treated similarly to the technological and behavioral relationships between the main effects of feedbacks. We also studied different effects that feedback produces as an IT impact.

Abstract: the control of the management is one of the aspects that today worry to directors about all the levels of the organizations. it is important to know the different tools displayed by the theoreticians and like it can be his application in areas or departments that are displaying results not satisfactory in the organization.
A produ??o de memória biotecnológica e suas conseqüências culturais
Ferreira, Jonatas;
Revista Brasileira de Ciências Sociais , 2003, DOI: 10.1590/S0102-69092003000300006
Abstract: biologic memory has traditionally been conceived as a sacred writing, whose syntax would be forever barred to the human being - he himself a product of divine word. given the recent advances in molecular biology, however, such syntax and writing have been unveiled and appropriated by tecnoscience. this paper investigates the relationship between the digitalization of life and the mathematical logics that determines the inner dynamics of this kind of scripture. aiming at establishing the fundamental relationship between mathematics and modern science, particularly as it emerges in cybernetics and molecular biology, the article seeks to identify the impact the archiving and edition of life might have in the western culture.
Concepts to Analyze the Vulnerability of Critical Infrastructures - Taking into account Cybernetics
Frédéric Petit,Beno?t Robert
Journal of Systemics, Cybernetics and Informatics , 2010,
Abstract: Critical Infrastructures (CIs) are complex systems. For their operations, these infrastructures are increasingly using Supervisory Control And Data Acquisition (SCADA) systems. Management practices are therefore highly dependent on the cyber tools, but also on the data needed to make these tools work. Therefore, CIs are greatly vulnerable to degradation of data. In this context, this paper aims at presenting the fundamentals of a method for analyzing the vulnerabilities of CIs towards the use of cyber data. By characterizing cyber vulnerability of CIs, it will be possible to improve the resilience of these networks and to foster a proactive approach to risk management not only by considering cybernetics from a cyber-attack point of view but also by considering the consequences of the use of corrupted data.
Conversa??es: modelo cibernético da constru??o do conhecimento/realidade
Pellanda, Nize Maria Campos;
Educa??o & Sociedade , 2003, DOI: 10.1590/S0101-73302003000400014
Abstract: this paper discusses the application of a methodology based on cybernetic principles to a group of education researchers, in the process of knowledge construction through conversational dynamics. conversation is one of the basic assumptions of humberto maturana's theory on biology of cognition, which is the core theoretical framework of this study.
Cybernetic structured modeling of the production of polyhydroxyalkanoates by Alcaligenes Eutrophus
Brazilian Journal of Chemical Engineering , 1999, DOI: 10.1590/S0104-66321999000200014
Abstract: this paper presents a cybernetic structured mathematical model developed for the fermentation step of the process of production of the copolymer of polyhydroxyalkanoates by the bacteria alcaligenes eutrophus. this process is performed in two different fermentation stages. the first emphasizes the growth of the microorganism in a batch operation without substrates limitations, while in the second, the focus is on copolymer production by a fed-batch operation in the absence of the nitrogen source. this paper presents the results of the treatment of experimental data and of preliminary parameter estimation. the fitting of the proposed model to the experimental data of a standard experiment showed a good agreement.
A sociedade cibernética
Vieira, Euripedes Falc?o;
Cadernos EBAPE.BR , 2006, DOI: 10.1590/S1679-39512006000200008
Abstract: this paper analyzes the changes that have occurred in society during its transition from industrial modernity to the cybernetic modernity. these periods were characterized by different events in the fields of technology, knowledge and information. changes that occurred in all segments of society in the last two decades have produced significant transformations in the cognitive framework, changing behavior and mechanisms of action and reaction in face of a new reality. clearly, this new reality has imposed itself and advanced as a cybernetic society, a cyberspace-time society with its still short narratives about economic, social and cultural events.
Tejiendo voces: jóvenes universitarios opinan sobre la apropiación de internet en la vida académica
Crovi Druetta, Delia;López González, Rocío;
Revista mexicana de ciencias políticas y sociales , 2011,
Abstract: in this article, the authors report some of the results of a wider investigation titled "technologies of information in the academic community of unam: access, use and adaptation". the object of this was to realize a diagnosis on the daily practices of the academic community in unam on access, use and adaptation of the information and communication technologies, tic, in education material. the results indicate that there are differences in areas as well as in the semester that the student courses, since while for the students of biological areas and health and physics-mathematics and engineering, the tic are fundamental resources the academic activities and life in general, for the students of social sciences these are instruments of socialization. humanities and arts, on the other hand, consider them as secondary tools in the academic sphere and of socialization. the knowledge on the resources offered by the unam increases to the degree in which the students take more advanced semesters not only thru a natural information, product of their daily university coexistence, but also for the need to realize their thesis for their degree.
International Journal of Bioinformatics Research , 2011,
Abstract: Fermentation products are indigenous to many civilizations, and they have been produced by industriessince a long time. Saccharomyces cerevisiae S288C (commonly known as baker's yeast) is the strain mainly usedin the Glucose based fermentation industries. We have seen the use of same yeast strain at different places withdifferent Phenotypic Constraints. The way to improve the adaptability of considered strain for desired phenotypicconditions, using smart selection of genes through cybernetic modeling is illustrated. Phylogenetic homologues forall S. cerevisiae S288c Glucose Fermentation pathway genes were screened to search evolutionarily relatedfunctional domains in other yeast strains like Saccharomyces cerevisiae YJM789, Candida glabrata CBS138,Kluyveromyces lactis NRRL Y-1140, Ashbya gossypii ATCC10895 etc., which are adapted naturally in different setof environment. We observed that Saccharomyces cerevisiae YJM789, Candida glabrata CBS138, Ashbyagossypii ATCC10895, Kluyveromyces lactis NRRL Y-1140 possess highly conserved functional domains, whichcan be carefully selected based on usage. This study aims at designing an algorithm to select and incorporateevolutionary homologues for genes of a considered strain, which mostly show sub-optimal performance in thedesired set of experimental constraints. Such a consideration of native microenvironment and evolutionarycloseness in the selection of functional homologues of the entire genetic set can thus be significantly fruitful.
The Intelligent Vehicle Coordination of the Cybernetic Transportation System
Fenghui Wang,Ming Yang,Ruqing Yang
International Journal of Advanced Robotic Systems , 2009,
Abstract: Cybernetic Transportation System (CTS) is a new branch of Intelligent Transportation Systems (ITS), which is a solution to the urban transportation problem. The coordination of intelligent vehicles is critical for the operation of the Cybernetic Transportation System. We present a distributed coordination approach for the intelligent vehicles of the Cybernetic Transportation System, which is based on an agent-based framework. Each vehicle agent generates intention independently by considering its and other agents' shared status and intentions in the coordination. Typical coordination scenes, including platoon and overtaking, have been demonstrated in the two-lane, two-way traffic situation and the effectiveness of the proposed coordination approach has been validated.
