The Center for Radiation Protection and Hygiene (CPHR) is the institution in Cuba that provides dosimetric calibration services of instruments at radiationl protection, radiotherapy, diagnostic radiology and interventionism level. This practice is developed by the Secondary Standard Dosimetric Laboratory and guarantees the metrological traceability of dose magnitudes to a Primary Standard Dosimetric Laboratory. It is carried out in compliance with a strict Radiation Protection Program designed to guarantee the radiation safety of people and the environment and to obtain the Operating License established in the national regulatory framework. The radiation protection program includes the necessary provisions to ensure the radiation protection of people while working with ionizing radiation sources. The safety of the personnel is one of the key elements of the program and is based on requirements such as radiological control both individually and of the workplaces, the design of the facilities, operational and safety procedures and inventory control, among other aspects that have allowed compliance with the annual dose constraints imposed by the Regulatory Authority for this category of exposed personnel. This paper presents the experiences in the application of these requirements for more than 20 years. [ABSTRACT FROM AUTHOR]

In the Yanuncay river that runs through the city of Cuenca, floods frequently occur due to the large discharge that flow through the river. The anticipated knowledge of these phenomena requires a detailed study of the rain-runoff relationship. In the present paper, the determination of this relationship was obtained through a calibration process with nine events (with maximum discharge contained in the range of 17, 1 to 101 m3 / s that occurred in two hydrometric stations) and a subsequent validation stage, with four new events, using for this the HEC-HMS program. The selected events for these stages allowed the process to be carried out, guaranteeing its representativeness for the flow interval with large return periods that could occur in the basin.

Precision and accuracy, which are common requirements in manufacturing processes, are defined by the manufacturing context, both from the specifications of the process and from the manufacturing system itself. In this context, the kinematic calibration of electromechanical systems contributes to achieve manufacturing requirements. This paper presents a kinematic calibration method for a CNC router that operates in a context of ISO 2768-c linear dimensional tolerances. The calibration method is based on the estimation of the parameters of a kinematic model with a representation of dimensional variations (linear and angular) of the structure. The estimation of the parameters is based on machining errors measured by monocular photogrammetry of a geometric pattern that records a machining. The calibration was implemented on a CNC machine by adjusting the G code, thus meeting the manufacturing requirements demanded by the proposed context. [ABSTRACT FROM AUTHOR]

The main objective of this paper is to create and calibrate a two-dimensional regional groundwater model for the "Cuentas Claras" aquifer. First, an overall model was conceived and it was subjected to a calibration process. For that purpose AQÜIMPE groundwater simulation software was applied. As the calibration was not achieved for the overall model, the idea of conceiving a partial model representing only the exploitation zone was carried through. The recharge coming from the mountains was introduced to this second model as a groundwater intake, and therefore it had to be calibrated as well. As a final result, a logical calibration of the model was achieved with high accuracy. The present work also attempts to contribute with the groundwater management strategies of this aquifer.

This paper proposes the use of random noise signals for the determination of the seismometers and accelerometers frequency response, as part of a device for device calibration which are the fundamental part of seismometric channel. The theory of the method is presented including mathematical relationship, considering these sensors as linear time invariant system (LTI) excited by stochastic signals and calculating the frequency response using these signals as a function of the Power Spectral Densities (PSD). Also, the main relationships and input - output equations defining the frequency response of these systems are shown and finally presented, for example, the calibration of very broad band sensor which is use extensive in seismic networks at national and international level.

One of the main objectives of EU climate and energy policy is to reduce energy dependency and "decarbonise" the economy. These policies have a considerable influence on the building sector, and where Directive 2010/31/EU on the energy performance of buildings establishes that all new buildings in the EU shall have to consume 'nearly zero-energy' as from 2021 and that all public authority owned or rented buildings apply these measures as from 2019. The analysis presented in this paper -focusing on the case of office buildings due to their far greater energy demands with respect to residential buildings- forms part of a study that attempts to examine the technical characteristics and economic feasibility of these "nearly zero-energy" buildings.

The anchoring effect is defined as the tendency of human thought to the fixation on certain pieces of information that affect decision-making. In the same context, the underconfidence bias is understood as an agent's propensity to underestimate his or her own objective performance. While some aspects of these phenomena are well known, there are no formal models that specifically describe the relationship between both. This paper presents: i) an experiment that illustrates the anchoring effect on the underconfidence bias by both reducing and amplifying such bias in the domain of geographic decision tasks and ii) the foundations of a new mathematical model that promotes precision in the study of the relationship between anchoring and underconfidence.

This paper develops the calibration of a system of data acquisition to monitoring the relative humidity in real time using the saturated solutions method, which produce constant relative humidity bath to a given temperature. Relative humidity sensor HIH3610 is introduced in that bath and finally it compared the experimental values of the sensor output voltage with the referenced values by the data sheet.
