This Operation Manual contains a schedule, operation procedures, operation log forms, a rectifier panel drawing, and pertinent reference matenal. Operation procedures and operating records are contained in the body of the manual, while blank operation forms, as built drawings, and pertinent reference material are contained in the appendices.

Final Report (SPR Project 90-00-RB10-012) on the Maintenance Asset Management Project Phase I, 2012

This project resulted in the development of a proof of concept for a features inventory process to be used by field staff. The resulting concept is adaptable for different asset classes (e.g. culverts, guardrail) and able to leverage existing DOT resources such as the videolog and LRS and our current technology platforms including Oracle and our GIS web infrastructure. The concept examined the feasibility of newly available technologies, such as mobile devices, while balancing ease of use in the field. Implementation and deployment costs were also important considerations in evaluating the success of the project. These project funds allowed the pilot to address the needs of two DOT districts. A report of findings was prepared, including recommendations for or against full deployment of the pilot solution.

Mikroyritysten tietotekniikkataitojen osaamisen kehittämismalli

Tämän tutkimuksen tavoitteena oli tuottaa koulutuksen kehittämismalli mikroyritysten tietotekniikkataitojen kehittämiseen. Työssä tarkasteltiin myös mikroyritysten asenteita tietotekniikan oppimiseen. Tutkimus tehtiin EU-projektiin nimeltä 'Mikrotie', jonka tavoitteena on estää mikroyritysten tietotekninen syrjäytyminen. Työ koostuu teoreettisesta ja empiirisestä osasta. Teoriaosassa kerrotaan konstruktivistisesta oppimisprosessista ja sen ympärille rakennetaan teoriaviitekehystä niin kouluttajasta kuin oppimisympäristöstä. Teoria keskittyy myös erityisesti aikuisopiskelijoiden erityispiirteisiin. Empiirisen osan aloittaa lomakekyselynä toteutettu kvantitatiivinen tutkimus mikroyritysten asenteista, jonka jälkeen käsitellään haastattelututkimuksena tehtyä tarkempaa kvalitatiivista osaa palveluntarjoajien ja mikroyritysten suhtautumisesta tapahtuneeseen koulutukseen sekä heidän parhaaksi katsomistaan koulutustavoista. Johtopäätösten mukaan aikuisoppimisen ja kouluttamisen asiantuntijan tulisi suunnitella mikroyritysten tietotekniikan koulutus tukenaan koulutettaviin asioihin perehtyneet palveluntarjoajat. Pelkästään vikojen korjailun sijaan mikroyrityksiä tulisi kouluttaa suuremmista asiakokonaisuuksista. Opiskelutavoitteet saavutetaan parhaiten vierikoulutuksena ja yleisemmän peruskäytön osalta pienryhmissä. Parhaana oppimisympäristönä toimisi yrityksen oma työskentelytila ja pienryhmäkoulutuksessa tietokoneluokka. Oppimistapahtumat pitäisi jakaa alle neljän tunnin osiin, jotka sijoiteltaisiin niin että opiskelu ei haittaa mikroyrityksen liiketoimintaa.

Coscheduling techniques and monitoring tools for non-dedicated cluster computing

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel performance against the local interactive response. Explicit and implicit coscheduling techniques in a PVM-Linux NOW (or cluster) have been implemented. Furthermore, dynamic coscheduling remains an open question when parallel jobs are executed in a non-dedicated Cluster. A basis model for dynamic coscheduling in Cluster systems is presented in this paper. Also, one dynamic coscheduling algorithm for this model is proposed. The applicability of this algorithm has been proved and its performance analyzed by simulation. Finally, a new tool (named Monito) for monitoring the different queues of messages in such an environments is presented. The main aim of implementing this facility is to provide a mean of capturing the bottlenecks and overheads of the communication system in a PVM-Linux cluster.

Integrating defeasible argumentation with fuzzy ART neural networks for pattern classification

Many classification systems rely on clustering techniques in which a collection of training examples is provided as an input, and a number of clusters c1,...cm modelling some concept C results as an output, such that every cluster ci is labelled as positive or negative. Given a new, unlabelled instance enew, the above classification is used to determine to which particular cluster ci this new instance belongs. In such a setting clusters can overlap, and a new unlabelled instance can be assigned to more than one cluster with conflicting labels. In the literature, such a case is usually solved non-deterministically by making a random choice. This paper presents a novel, hybrid approach to solve this situation by combining a neural network for classification along with a defeasible argumentation framework which models preference criteria for performing clustering.

Teaching fundamentals of computing theory: a constructivist approach

A Fundamentals of Computing Theory course involves different topics that are core to the Computer Science curricula and whose level of abstraction makes them difficult both to teach and to learn. Such difficulty stems from the complexity of the abstract notions involved and the required mathematical background. Surveys conducted among our students showed that many of them were applying some theoretical concepts mechanically rather than developing significant learning. This paper shows a number of didactic strategies that we introduced in the Fundamentals of Computing Theory curricula to cope with the above problem. The proposed strategies were based on a stronger use of technology and a constructivist approach. The final goal was to promote more significant learning of the course topics.

Formalizing defeasible argumentation using a labeled deductive system

In the last years there has been an increasing demand of a variety of logical systems, prompted mostly by applications of logic in AI, logic programming and other related areas. Labeled Deductive Systems (LDS) were developed as a flexible methodology to formalize such a kind of complex logical systems. In the last decade, defeasible argumentation has proven to be a confluence point for many approaches to formalizing commonsense reasoning. Different formalisms have been developed, many of them sharing common features. This paper presents a formalization of an LDS for defensible argumentation, in which the main issues concerning defeasible argumentation are captured within a unified logical framework. The proposed framework is defined in two stages. First, defeasible inference will be formalized by characterizing an argumentative LDS. That system will be then extended in order to capture conflict among arguments using a dialectical approach. We also present some logical properties emerging from the proposed framework, discussing also its semantical characterization.

What to consider for applying backfilling on non-dedicated environments

The resource utilization level in open laboratories of several universities has been shown to be very low. Our aim is to take advantage of those idle resources for parallel computation without disturbing the local load. In order to provide a system that lets us execute parallel applications in such a non-dedicated cluster, we use an integral scheduling system that considers both Space and Time sharing concerns. For dealing with the Time Sharing (TS) aspect, we use a technique based on the communication-driven coscheduling principle. This kind of TS system has some implications on the Space Sharing (SS) system, that force us to modify the way job scheduling is traditionally done. In this paper, we analyze the relation between the TS and the SS systems in a non-dedicated cluster. As a consequence of this analysis, we propose a new technique, termed 3DBackfilling. This proposal implements the well known SS technique of backfilling, but applied to an environment with a MultiProgramming Level (MPL) of the parallel applications that is greater than one. Besides, 3DBackfilling considers the requirements of the local workload running on each node. Our proposal was evaluated in a PVM/MPI Linux cluster, and it was compared with several more traditional SS policies applied to non-dedicated environments.

CISNE-P: a global scheduling oriented to NOW environments

In this work, we present an integral scheduling system for non-dedicated clusters, termed CISNE-P, which ensures the performance required by the local applications, while simultaneously allocating cluster resources to parallel jobs. Our approach solves the problem efficiently by using a social contract technique. This kind of technique is based on reserving computational resources, preserving a predetermined response time to local users. CISNE-P is a middleware which includes both a previously developed space-sharing job scheduler and a dynamic coscheduling system, a time sharing scheduling component. The experimentation performed in a Linux cluster shows that these two scheduler components are complementary and a good coordination improves global performance significantly. We also compare two different CISNE-P implementations: one developed inside the kernel, and the other entirely implemented in the user space.

Los observatorios de la Sociedad de la Información: evaluación o política de promoción de las TIC en educación.

Este artículo trata de responder a la pregunta formulada en el título acerca de si los observatorios de la Sociedad de la Información tienen como principal finalidad llevar a cabo una evaluación sobre el impacto de las tic, o si constituyen una promoción de su uso en la educación. Para responder a esta interrogante hemos realizado, en primer lugar, una aproximación al concepto de observatorio y a su función en el ámbito de las Ciencias Sociales, así como al de Sociedad de la Información. Tras identificar el conjunto de observatorios accesibles desde Internet en las lenguas del Estado español, procedimos al análisis de sus promotores, de sus finalidades y objetivos, y de sus contenidos. La interpretación de los datos del análisis nos permitió llegar a la conclusión de que el principal interés y la motivación de estas iniciativas son la expansión y el fomento del uso de las tic en todos y cada uno de los ámbitos económicos, políticos, sociales, culturales y formativos. Por otro lado, aunque parece entenderse que la educación es una necesidad fundamental en el desarrollo de la Sociedad de la Informaciónque algunos comienzan a convertir en Sociedad del Conocimiento, sólo uno de los observatorios estudiados (hoy anticuado) está dedicado a valorar la evolución del uso de las tic en la mejora de la calidad educativa. En el resto el tema de la educación, cuando aparece, lo hace como cualquier otro, y no siempre como el más destacado entre muchos. De ahí que se concluya que el tema de la política de promoción de las tic en educación parezca más una acción indirecta, que se conseguiría a partir de generalizar el uso de estas herramientas en todos y cada uno de los espacios personales y sociales de los individuos.

Broadening the CRM domain of application to higher educational (e-learning) environments

In this paper, we reflect about the broadening of the field of application of CRM from the business domain to a wider context of relationships in which the inclusion of non-profit making organizations seems natural. In particular, we focus on analyzing the suitability of adopting CRM processes by universities and higher educational institutions dedicated to e-learning. This is an issue that, in our opinion, has much potential but has received little attention in research so far.
