Opis:
In this paper we examine the narrative formulae of the Cantar de Mio Cid (CMC) in order to trace phenomena of the transposition of the original deictic reference they include. As a result, it is argued that the formulae used by the narrator of the CMC may have a phatic function as they absorb the perspective of the addressee: either by a centripetal or a centrifugal movements of the narration. Uso del componente deíctico en las fórmulas narrativas del Cantar de Mio Cid 21 Moreover some expressions seem to serve (intratextually) to organize the informational pattern of the plot by enhancing the epic text with an additional meaning. Finally, it is concluded that the analysis of the pragmatic component of the CMC may add some new insights for its literary, linguistic and textual construction.

Opis:
The measurements of geometrical distribution of thermal neutron flux in research reactors are often used in the field of reactor operation and reactor physics. Usually such measurements are carried out by using the gold wire activation method. This method has been used for measuring a thermal neutron flux at the location of a Cobalt Irradiation Device (CID) of ETRR-2. A special device was used for locating samples in an irradiation box and the measurements were performed for seventy-two positions. The Monte Carlo MCNP-4B code has been used for the modeling and simulation of ETRR-2 core with structural materials and surrounding beryllium reflectors. The device used in the flux measurement was also simulated in the MCNP-4B model. The thermal flux has been calculated and compared with the experimental one. The results show good agreement between the measured and calculated flux.

Opis:
In this paper, we address the pursuit-evasion problem of tracking an Omnidirectional Agent (OA) at a bounded variable distance using a Differential Drive Robot (DDR), in an Euclidean plane without obstacles. We assume that both players have bounded speeds, and that the DDR is faster than the evader, but due to its nonholonomic constraints it cannot change its motion direction instantaneously. Only a purely kinematic problem is considered, and any effect due to dynamic constraints (e.g., acceleration bounds) is neglected. We provide a criterion for partitioning the configuration space of the problem into two regions, so that in one of them the DDR is able to control the system, in the sense that, by applying a specific strategy (also provided), the DDR can achieve any inter-agent distance (within an error bound), regardless of the actions taken by the OA. Particular applications of these results include the capture of the OA by the DDR and maintaining surveillance of the OA at a bounded variable distance.

Opis:
The union of different devices in order to obtain a specific response for a process is commonly called a control system. For a control system, it is necessary to have one or more controllers. Among the most used in the industrial sector are the PID and PI controllers. Next to these controllers is the control software. Scilab is a good example of control software. It is characterized as free code software, with no cost for its acquisition, in addition to having a large computational power and integrated tools, such as Xcos, intended for modeling and simulation. For the union with Scilab, there is Arduino. Such a mixture can be used, for example, to control liquid levels in tanks. In this context, the present work aims to study the tank-level control system based on PID and PI controllers through the union between Scilab and Arduino. Phenomenological models were developed based on closed-loop control (feedback control system) of the process with two tanks not coupled with recycle. Furthermore, for comparison purposes, two approaches were used for each process: one considering the saturation of the manipulated variable and the other without the presence of such saturation. At first, there was a need to implement an anti-windup system. For tuning the controller parameters, the ISE method was used, executed through a programming code developed in Scilab. The parameters found for the two systems were tested on a made-up experimental bench. Therefore, using the block diagrams and the method here called “ISE method”, satisfactory values were obtained for the control parameters. These were ratified in the tests carried out in the experimental module. Level control was achieved with greater prominence for the PI controller since there is one less parameter to be tuned and processed by the system. This controller provided results close to the PID controller for cycles up to 50%. In general, the PI controller showed maximum response deviations smaller than the PID, such as deviations of 1.55 cm and 2.40 cm, respectively, for the case with 75% recycle. It was also clear the influence of the saturation of the manipulated variable on the system response, but not on the tuning of the controller parameterseters.

Opis:
Desde que Les cadres sociaux de la mémoire de Halbwachs en 1925 postulou a construción social da memoria colectiva, as Ciencias Sociais non desatenderon os estudos sobre a memoria, xa fose enfocando o seu carácter normativo ou a súa relación coa historia. Hoxe, esta asúmese como un mecanismo de reconstrución e resignificación dos elementos presentes ou incorporábeis ao imaxinario social por intereses diversos. Observando a produción poética galega da década dos 90 (e non só), percíbese a reiteración de certos elementos ligados á historia e á construción da memoria nacional, entre os que podemos atopar desde mencións ao imaxinario atlantista ou medieval, até interdiscursividade e intertextualidade coa literatura popular ou reescrituras da historia literaria. Ao sermos conscientes da ligazón destes marcos coa fabricación das identidades nacionais, e sen deixar de considerar o sistema galego como un sistema se non emerxente, si en loita pola súa definición e contraste, é pertinente cuestionar se certas escollas na produción poética constituíron unha norma de repertorio na altura dos 90. Reformulada por Torres Feijó (2004), esta noción de Itamar Even-Zohar designa aqueles elementos que non delimitan sistemas, pero son promovidos por dotaren de maior xenuinidade os produtos propios dunha comunidade. Nun sistema no que a historiografía e a historia literaria se alicerzaron retroalimentándose, no que a relación entre construción da identidade e construción dun sistema literario propio é decisiva, faise máis nutricia esta revisión.

Opis:
Some recent accident reports involving large vessels in mooring operations or breaking away from their moorings conclude that brakes of mooring winches do not render before line parts. As the potential loss of life is high, the utmost attention on-board must be paid to minimise this inherent risk. When the load on the mooring lines becomes overloaded beyond the pre-set levels, mooring winches band brakes have the safety function of rendering and allowing the line to shed this load before its potential breaking and the subsequent snap-back. As a preventive measure against breaking, the pre-set level, known as Brake Holding Capacity (BHC), must be below the Minimum Breaking Load (MBL) of the line. In this paper, the authors analyse concerns that can arise from those with conventional screw manually-applied band brakes regarding their BHC reliability. Thus, in order to improve safety, the advantages of the spring-applied band brakes with manual setting and release or with hydraulic release are highlighted. Finally, the paper shows a typical procedure using a hydraulic jack for brake testing the winch of a Liquefied Natural Gas (LNG) ship to fix their BHC in order to hold 60% of the MBL of the mooring line.
