Phenylketonuria felnőttkorban
Authors: Sumánszki Csaba , Barta András Gellért , Reismann Péter
Published: November 2017

Abstract:

Starting from 1975 phenylketonuria is part of the newborn screening program in Hungary. Since then a generation, treated with special diet and medical foods right after neonatal diagnosis has reached adulthood. Thanks to early treatment initiation, children with phenylketonuria are able to lead life to the full. Consequently, phenylketonuria is no longer considered a pediatric disease. Follow up of adult patients with phenylketonuria is performed in internal medicine centers specialized in metabolic diseases. The outcome of the lifelong special treatment, and the particularities of phenylketonuria in adulthood are yet to be determined. The aim of our review is to present recent findings in phenylketonuria focusing mainly on the adult care. After long time the first international guidelines appeared, new therapies were put in use, and these current developments are expected to be implemented in daily practice in the near future. New challenges must be met such as maternal phenylketonuria, long term effects of dietotherapy and the sequelae of untreated phenylketonuria in adulthood. Orv Hetil. 2017; 158(46): 1857–1863.
Do high-fidelity, augmented reality simulations improve students’ engagement with simulation sessions?
Authors: Thompson Oliver David , Harris Rhydian , Godfrey Tim
Published: November 2017

This article was migrated. The article was not marked as recommended. Simulation is used extensively in medical education, where it allows students to train safely and develop both clinical and non-clinical skills. However, many scenarios are low-fidelity and the lack of realism can psychologically remove students from those scenarios. This lack of engagement can be detrimental to student learning.We produced a scenario utilising numerous sensory augmentations, including olfactory, auditory and visual, with the aim of increasing the realism of the scenario. This scenario ran twice, with and without the augmented components, and students' engagement with the scenarios was measured using a questionnaire.Due to the small number of students taking part in the study (six), a full statistical analysis of the results was deemed inappropriate. The students in the augmented scenario reported that they felt the simulation felt more realistic. However, in some measures of engagement the non-augmented scenario received higher scores. Many augmented-reality features, especially the video-handover, received positive feedback and were viewed as successful in improving realism and engagement.We believe that augmenting simulation scenarios has the potential to improve engagement and retention of knowledge and skills. Further work is required, involving greater numbers of students and more robust methods of measuring engagement and knowledge retention.

Published: November 2017

Las niñas y jóvenes en situación de desamparo presentan deficiencias de salud mental que deterioran gravemente su bienestar biopsicosocial. Mundialmente casi no hay instrumentos de evaluación para esta población. Consecuentemente, se carece de diagnósticos fiables. Propósito: se realizó este estudio preliminar para adaptar y validar escalas de medición de síntomas ansiosos y depresivos, asertividad y regulación emocional en 413 niñas y jóvenes mexicanas en situación de desamparo de entre 6 y 23 años de edad (M[DT]=11.75[2.78]). Metodología: se llevaron a cabo tres estudios piloto y la versión final de los cuestionarios se aplicó a 240 participantes del total. Hallazgos: los resultados alcanzados muestran estimados de validez y fiabilidad que determinan la veracidad de las características psicométricas de las escalas. Según el análisis factorial confirmatorio efectuado, se obtuvieron índices de ajuste y de validez discriminante y convergente apropiados constatando aún más que dichas pruebas pueden ser retomadas para futuras aplicaciones con poblaciones similares. Originalidad: la utilidad del estudio estriba en que se tienen, por primera vez en México, instrumentos preliminares para medir sintomatología ansiosa y depresiva, conductas asertivas y estrategias de regulación emocional en niñas y jóvenes en situación de desamparo.

Authors: NEGOIȚĂ Ionuț Șerban , BĂLĂCEANU Rosalie Adina , DOJANĂ Nicolae
Published: November 2017

The experiments were carried out on four groups of Hy-Line var. Brown hens (n = 350 each) monitored from 20 to 68 weeks of age. The hens were fed on diets which provided the following calcium intakes (%): 2.56 and 3.12 in groups I and II, respectively, 3.86 in control and 4.22 in group III. The shell weight increased during the laying period proportionally to the ingested calcium. The thickness of the eggshell decreased: the decrease was higher in the groups which ingested less calcium. The eggshell strength increased from 20 to 36 weeks of age in all the hen groups. Further, the eggshell strength decreased from 36 to 68 weeks of age. These decreases were higher as the amount of calcium intake increased. In conclusion, calcium diet influences on eggshell properties are age-dependent and more pronounced at the peak of laying period. The increase in diet calcium content from 3.86 to 4.22% has less and negative influences on the physical properties of the eggshell.

EXPORT POTENTIAL AND POSSIBILITIES OF UKRAINIAN SMALL AND MEDIUM SIZE ENTERPRISES IN THE EUROPEAN MARKET
Authors: Lytvyn O.
Published: November 2017

This article deals with the export potential and possibilities of the Ukrainian small and medium size enterprises in the European market as well as markets of the third countries, especially after acting of the deep and comprehensive free trade area («FTA+») between Ukraine and the EU. Most of the articles of the Association Agreement between the EU and Ukraine concern the terms of business, competition defence in the market i.e. liberalization and removal of different administrative and discriminatory measures in Ukraine. The access to the market of the EU for the domestic small and medium size entrepreneurial activity players must be considerably broaden. In the case of the European market entry, the Ukrainian businessman, adjusting to the requirements of all countries-members of the EU, will be able to get a considerable competitive advantage as a mediator or intermediate link among the economic players of the EU countries.
The consequences of adaptation of the technical adjusting, corporate management, defence of consumer rights and competition are analysed at the same time. The achievement of results on these questions is non-equivalent and has contradictions in the Ukrainian terms. The unwillingness of «FTA+» is exposed by the most Ukrainian economic players in separate market niches. The main reason is the expulsing of domestic products in the internal market by the European commodities and impossible access to the EU markets due to the competition and disparity of the Ukrainian standards to the European requirements. There are recommendations in relation to the effective implementation of the foreign economic activity of small and medium size enterprises, and increase of the products’ competitiveness of the domestic producers in the European market.
THE ACTIVITIES OF THE KING OF ENGLAND HENRY VIII AND CARDINAL THOMAS WOLSEY AS PART OF THE "ITALIAN WARS" IN THE XVI CENRURY
Authors: Rzhevskaya V.
Published: November 2017

A significant event of international politics of the Renaissance epoch was that of the so-called «Italian wars» (1494-1559), that had as their part a great number of agreements on military alliances. On one hand those agreements testified the infidelity and quick changeability of the alliances they were meant to give form to, on the other hand they reflected the ideas of their members as to the substance of international security and the means to attain their political aims under the guise of its reestablishment and protection. The article sums up the treaty undertakings of the King of England Henry VIII, taken within the context of the «Italian wars» with the active part of his chief minister at the period, Cardinal Thomas Wolsey. Of the agreements looked upon the main importance is acknowledged with the London treaty of 1418, as with one of historical projects of the all-European collective security, that acquired the form of an international treaty. With the help of the analysis of the other treaties’ contents, the main features of legal undertakings in the field of security, characteristic of the period, can be defined. Attention is also paid to the legal grounds of the two Holy Leagues (of 1495 and 1511).
To study and evaluate the effect of intravenous lignocaine on haemodynamic responses to intubation, extubation and post‐operative analgesia in laparoscopic cholecystectomy surgeries
Authors: S. Amitha , P. V. Vinay
Published: November 2017

Background: Laryngoscopy, tracheal intubation and subsequent extubation are often associated with an increase in arterial blood pressure (BP), heart rate, arrhythmias, and raised intracranial and intraocular pressure. Lignocaine as bolus I.V. dose just prior to tracheal intubation or extubation has been effectively used to decrease haemodynamic responses associated with them.Methods: Double blinded Randomized Controlled Trial was undertaken at Department of Anesthesia, Sri Siddartha Medical College for a period of one year among ASA 1 and 2 patients. Group A: 0.9% normal saline was used as placebo for perioperative intravenous infusion. Group B: Preservative free lignocaine (xylocard) diluted with normal saline and made to 1% used as intravenous infusion started at a dose of 1.5 mg per kg of lignocaine given as bolus over 10 minutes before induction followed by an infusion of 1.5mg/kg/hr till 1 hour post op.Results: There was significantly less rise in PR and MAP in Group B as compared to Group A. It was also seen that during tracheal extubation there was significantly less rise in PR and MAP in the Group B as compared to the Group A.Conclusions: Administration of lignocaine infusion attenuates the rise in PR as well as MAP duringthe peri‑intubation and peri‑extubation period. Furthermore, infusion of lignocaine significantly increases the mean pain‑free period post‑operatively.

In this paper, we present a numerical study of surface plasmon resonance (SPR) excitation in a bent single-mode optical fiber with metallized cladding. It is shown that with a suitable combination of the bending radius and metal film thickness, surface plasmon waves can be excited in the film as a result of coupling between the fundamental and surface plasmon modes via whispering gallery modes (WGM) supported by the bent fiber cladding. The coupling brings about a dip in the transmission spectrum at the resonant wavelength which is strongly dependent on the ambient refractive index, thus, making it possible to build an SPR- refractometer based on a single-mode fiber without breaking the structural integrity of the fiber or using any additional elements. The refractometric sensitivity of ~12 mm/RIU are demonstrated.

This work shows the possibility of estimating errors of super-resolution imaging based on the use of several frames. The possibility of identifying areas with large interpolation errors is shown, based only on the interpolation method and interpolated data used. The possibility of determining the necessary number of frames used for imaging from the interpolation error estimate is demonstrated. In this paper, we present both the results of interpolation of the generated test frames, the method of correlation subpixel detection of frame shifts relative to 1 frame, and the estimates of the resulting interpolation errors. It is shown that before measurements, the number of frames necessary to achieve the required level of interpolation errors can not be predicted. The proposed method allows the error value to be controlled during the measurement. It is shown that the estimation of errors of the super resolution method based on test images is not very promising, since the error value depends both on the image itself and on a set of subpixel offsets of low-resolution frames. We discuss the entire procedure of obtaining the results of the work, starting from the test image generation and ending with the conclusions.

Arcadias bajo vidrio
Authors: Prieto Eduardo
Published: November 2017

Los invernaderos se han visto tradicionalmente como poco más que una anécdota en la historia de la construcción, aunque en realidad fueran el tipo arquitectónico más innovador del siglo XIX. Conjugando la rigurosa atención a los problemas del clima con el uso de los materiales industriales y los nuevos sistemas de calefacción, los invernaderos dieron pie a soluciones formales y técnicas extremadamente eficaces, que están en la base del diseño pasivo contemporáneo. Este artículo da cuenta de los orígenes del invernadero, de su desarrollo y consolidación como tipo termodinámico, y de su rápida extrapolación a otros usos convertido ya en ‘pseudomorfo’, para acabar desvelando su íntima relación con las llamadas ‘casas solares’ del siglo XX. Todo ello a la luz de una pulsión de calado en la tradición moderna: la búsqueda improbable de un clima completamente artificial.

Las viviendas de la colonización alemana en el sur de Chile
Authors: Tilleria González Jocelyn , Vela Cossio Fernando
Published: November 2017

La ocupación efectiva del territorio austral chileno se produjo en la segunda mitad del siglo XIX. Para su ejecución fueron claves las medidas dictadas por el Estado a través del denominado “proyecto de colonización”, que favoreció la llegada de inmigrantes procedentes de Europa durante un periodo de grandes flujos migratorios hacia el continente americano. La ciudad de Valdivia fue el punto de partida de este proyecto. En 1845 desembarcan los  pobladores procedentes de los territorios de la Confederación Alemana. En esta ciudad se producen los primeros intercambios culturales entre la población local y la extranjera, en un “laboratorio constructivo” que estableció las bases de la arquitectura de la colonización y determinó la formación de la vivienda tradicional del sur del país. Mediante un estudio histórico y constructivo hemos identificado los invariantes arquitectónicos generados en este periodo de la colonización. Hemos comprobado su permanencia en distintos ejemplos de viviendas tradicionales localizadas, entre las ciudades de Valdivia y Puerto Montt, a lo largo del territorio que fue ocupado entre 1845 y 1875 con esta población alemana.
El Pabellón Suizo y el Colegio de España en París
Authors: Alonso Pereira José Ramón
Published: November 2017

La Cité Internationale Universitaire de París vio la luz en una Europa que, tras la Guerra de 1914-1918, reformulaba sus modelos universitarios. Sus edificios presentan un amplio registro arquitectónico que pasa de los estilos nacionales a la modernidad, haciendo de la Cité un reflejo de la pluralidad de la arquitectura del siglo XX.El Pabellón Suizo y el Colegio de España reflejan esa pluralidad (Figura 1). Si el Pabellón es emblema de la modernidad y de la arquitectura corbuseriana, el Colegio simboliza los compromisos aún vigentes con la tradición. La coincidencia del programa y el paralelismo del lugar permiten confrontarlos y analizarlos comparativamente.Basado en documentos depositados en la Cité Universitaire, el Pabellón Suizo, el Colegio de España y otros archivos, este trabajo se propone explicar y analizar su arquitectura, oponiendo ambas obras para entenderlas mejor y entender así un tiempo histórico que se debate en toda Europa entre tradición y vanguardia.
Spectral and Spatial Cloud Detection Onboard for Hyperspectral Remote Sensing Image
Authors: Li Haoyang , Zheng Hong , Han Chuanzhao , Wang Haibo , Miao Min
Published: November 2017

It is strongly desirable to accurately detect the clouds in hyperspectral images onboard before compression. However, conventional onboard cloud detection methods are not appropriate to all situation such as shadowed cloud or darken snow covered surfaces which are not identified properly in the NDSI test. In this paper, we propose a new spectral–spatial classification strategy to enhance the orbiting cloud screen performances obtained on hyperspectral images by integrating threshold exponential spectral angle map (TESAM), adaptive Markov random field (aMRF) and dynamic stochastic resonance (DSR). TESAM is performed to classify the cloud pixels coarsely based on spectral information. Then aMRF is performed to do optimal process by using spatial information, which improved the classification performance significantly. Some misclassification points still exist after aMRF processing because of the noisy data in the onboard environment. DSR is used to eliminate misclassification points in binary labeling image after aMRF. Taking level 0.5 data from hyperion as dataset, the average overall accuracy of the proposed algorithm is 96.28% after test. The method can provide cloud mask for the on-going EO-1 images and related satellites with the same spectral settings without manual intervention. The experiment indicate that the proposed method reveals better performance than the classical onboard cloud detection or current state-of-the-art hyperspectral classification methods.

Authors: Boretti Albert , Castelletto Stefania , Al-Zubaidy Sarim
Published: November 2017

The paper examines design and operating data of current concentrated solar power (CSP) solar tower (ST) plants. The study includes CSP with or without boost by combustion of natural gas (NG), and with or without thermal energy storage (TES). The latest, actual specific costs per installed capacity are very high, 6085 $/kW for Ivanpah Solar Electric Generating System (ISEGS) with no TES, and 9227 $/kW for Crescent Dunes with TES. The actual production of electricity is very low and much less than the expected. The actual capacity factors are 22% for ISEGS, despite combustion of a significant amount of NG largely exceeding the planned values, and 13% for Crescent Dunes. The design values were 33% and 52%. The study then reviews the proposed technology updates to produce better ratio of solar field power to electric power, better capacity factor, better matching of production and demand, lower plant’s cost, improved reliability and increased life span of plant’s components. The key areas of progress are found in materials and manufacturing processes, design of solar field and receiver, receiver and power block fluids, power cycle parameters, optimal management of daily and seasonal operation of the plant, new TES concepts, integration of solar plant with thermal desalination, integration of solar plant with combined cycle gas turbine (CCGT) installations and finally, specialization and regionalization of the project specification.

Published: November 2017

Bottom-up synthesis of porous NiMo alloy reduced by NiMoO4 nanofibers was systematically investigated to fabricate non-noble metal porous electrodes for hydrogen production. The different annealing temperatures of NiMoO4 nanofibers under hydrogen atmosphere reveal that the 950 °C annealing temperature is a key to produce bicontinuous porous NiMo alloy without oxide phases. The porous NiMo alloy as cathodes in electrical water splitting demonstrates not only almost identical catalytic activity with commercial Pt/C in 1.0 M KOH solution, but also superb stability for 12 days at an electrode potential of −200 mV (v.s. RHE).

Published: November 2017

Dynamic laser speckle is applied as a reliable sensor of activity in all sort of material. Traditional applications are based on a time rate that is usually higher than 10 frames-per-second (FPS). Even in drying processes, where there is a high activity in the first moments after the painting and a slow activity after some minutes or hours, the process is based on the acquisition of images in a time rate that is the same in both moments of high and low activity. In this work, we present an alternative approach to follow the drying of paint and the other processes related to restauration of paintings that takes long-term to reduce the activity. We illuminated, using three different wavelength lasers, an accelerator (Cyclododecane) and a varnish used in restauration of paintings and monitor them at long-term drying using an alternative fps, comparing the results to the traditional method. The work also presents a way to do the monitoring using a portable equipment. The results present the feasibility to use the portable device and show the improvement in the sensitivity of the dynamic laser speckle to sense long-term process regarding the drying of Cyclododecane and Varnish used in restauration.

We would like to suggest that, by considering three virtual gravitational constants assumed to be associated with gravitational, electromagnetic and strong interactions along with a strongly interacting virtual nuclear elementary charge, a workable model of final unification can be developed. In a verifiable approach, Newtonian gravitational constant and Fermi’s weak coupling constant can be interrelated via nuclear and electromagnetic gravitational constants.

This work aims to tackle the following two research questions regarding post-disaster rescues: how to optimize the rescue team dispatch based on the specialties of the team and the type of damage incurred, and how to optimize the allocation of injured patients to hospitals based on their symptoms, the rescue teams allocated, and the abilities of the hospitals to minimize fatalities. Rather than handling these two problems separately, we formulate them into an integrated system. A real-coded genetic algorithm is applied to minimize the estimated transport time in terms of distance, and the disparity between resource supply and demand. A set of scenarios is simulated and analyzed to provide insight for policy makers. Further, the simulated results can be used for future post-disaster medical assistance training.

To enable us to select only the specific scenes that we want to watch in a baseball video and personalize its highlights sub-video, we require an Automatic Baseball Video Tagging system that can divide a baseball video into multiple sub-videos per at-bat scene automatically and append tag information relevant to at-bat scenes. Towards developing the system, the previous papers proposed several Tagging algorithms using ball-by-ball textual reports and voice recognition, and tried to refine models for baseball games. To improve its robustness, this paper proposes a novel Tagging method that utilizes multiple kinds of play-by-play comment patterns for voice recognition which represent the situation of at-bat scenes and take their “Priority” into account. In addition, to search for a voice-recognized play-by-play comment on the start/end of at-bat scenes, this paper proposes a novel modelling method called as “Local Modelling,” as well as Global Modelling used by the previous papers.

Technology Update: Lowering Adoption Barriers to MPD - Land and Sea
Authors: Kamps Charley , Dow Blaine
Published: November 2017

Technology Update

In the past, most wells have been drilled using conventional methods, but the landscape is changing as economic pressures have forced the drilling industry to refocus. Attention is at an all-time high on technologies that deliver operational efficiency and improve safety. Operators, drilling contractors, and service companies have gone through exhaustive measures to reduce cost, refine efficiency, optimize asset performance, and maximize returns. The recently introduced Schlumberger Managed-Pressure Drilling Integrated Solution offers a significant impact in all of these areas.

Managed-pressure drilling (MPD) is an adaptive drilling process used to precisely control the annular pressure profile throughout the wellbore. In conventional drilling, the system is open to the atmosphere. However, with MPD, a closed-loop circulation system is created. The closed-loop system is the key element, as it enables control of the annular pressure profile through the application of surface pressure.

MPD can dramatically improve operational efficiency through the reduction of nonproductive time associated with influxes, mud losses, and stuck-pipe events. The closed-loop system improves safety by providing an increased awareness of pressure state in the well and facilitates a much higher level of control with quicker response.

The MPD drilling technique has been around for many years on land but is relatively new to deep water, as the needed technologies have only become available in the past 5 to 7 years.

While manual chokes have been the principal form of control of MPD operations since the technique was introduced, it has been noted that the consistency and repeatability of manual methods is only as good as the choke operator’s skill and the level of experience and teamwork between the driller and the choke operator. For this reason, automated MPD was introduced, and a solution now exists that addresses the many challenges associated with MPD operations.

A Shifting Business Case

Historically, MPD components have been owned and leased through various service companies. Operators have called out multiple providers to deliver the kit and execute the service.

Deepwater MPD requires substantial planning and financial investment, which has typically recurred with each call-out. On top of that has been the need to coordinate multiple service providers to work with the drilling contractor so that the system is properly integrated.

Given these requirements, operators have tended not to use the technique unless the well or hole section they are planning cannot be drilled without it. For the most part, MPD in deep water has been a contingency solution rather than a standard practice.

It is difficult to build a reasonable business case around a contingency solution or a call-out service that requires such significant investment and has multiple variables at stake. Additionally, service companies must charge a premium to ensure a sufficient return on their investment.
Building Type Wells for Appraisal of Unconventional Resource Plays
Authors: Carpenter Chris
Published: November 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 185053, “Building Type Wells for Unconventional Resource Plays,” by P. Miller, N. Frechette, and K.D. Kellett, Repsol, prepared for the 2017 SPE Canada Unconventional Resources Conference, Calgary, 15–16 February. The paper has not been peer reviewed.

Although the application of statistical techniques to type wells is gaining acceptance, it is often unclear to evaluators how these techniques can be applied to capture accurately the full range of uncertainty in the average single-well estimated ultimate recovery (EUR) for a geologic subset. The objective of the complete paper is to present an integrated work flow that can be used to build P90, mean, and P10 type wells, which represent the range of potential outcomes for the geologic subset in an unconventional resource play.

Introduction

A common challenge that accompanies new technologies dedicated to the discovery of unconventional resources is how to forecast production and quantify EUR. Early in the life of a resource play, it can be difficult to build type wells because of limited production history and a small well count.

Traditional methods would use an analogous-field well model or decline methods to predict future production. Because of unconventionals being a relatively recent development, no late-life fields exist that can be used as direct analogs to understand mid- to late-time horizontal-well behavior in tight unconventional formations. For plays in the early stages of development, because of the relatively small well count and difficulty with a direct analog, the early-time well behavior is also not easily predicted with confidence. There is thus a high degree of uncertainty in both the shape and the magnitude of the type-well profile. Consequently, it is becoming more common for management to ask for an expected type well with a range to capture uncertainty, rather than a single deterministic estimate. The work flow in this paper applies such methods.

Methodology

Acknowledging Uncertainty. For unconventional resource plays, the two basic sources of uncertainty are the drilling-and-completion (D&C) design and the geological properties that characterize the reservoir. Ideally, one would select a statistically significant number of wells with identical (or nearly identical) geological properties, completions, lateral length, and drilling azimuth to construct type wells. However, this scenario is often far from reality.

One solution is to wait until enough wells exist with nearly identical D&C designs and geological properties before proceeding with type-well construction. Obviously, this solution is not practical if management needs to rank assets in the portfolio and justify capital allocation for development of some assets but not others. Therefore, alternative solutions to deal with varying D&C designs and geological properties are to normalize production data for D&C design and to define geologic subsets for areas with similar geological properties.
Eliminate Decision Bias in Facilities Planning

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 187283, “Eliminate Decision Bias in Facilities Planning,” by Z. Cristea, Stochastic Asset Management, and T. Cristea, Consultant, prepared for the 2017 SPE Annual Technical Conference and Exhibition, San Antonio, Texas, USA, 8–11 October. The paper has not been peer reviewed.

The complete paper holds the traditional facilities-planning methodologies, heavily based on design-basis documents and biased toward the most-conservative conditions, fail to recognize the entirety of operational conditions throughout the oilfield life cycle, leading to significant residual risk and the wastage of resources in the operations stage. An integrated stochastic approach is proposed, accounting for both subsurface and surface uncertainties and their interrelations throughout field life.

Introduction

The authors discuss an unbiased, data-driven stochastic work flow addressing the effect of subsurface uncertainties on surface-facilities design and operational decisions. Unlike classical design approaches, in which the most-conservative values are typically used as design input variables and assembled into design-basis documents, the stochastic work flow accounts for design-input-variable distribution and combination throughout the entire system life cycle. An example case is provided in which a flow-assurance risk is managed and chemical consumption optimized in a wet-gas field development.

Theory and Definitions

Oil and gas engineering projects are typically processes of high variety, low volume, and intermittent productivity, and with a high rate of diversification and complexity. Conversely, oilfield-facilities operations are expected to be continuous, characterized by high volumes and low variety. This expectation is reflected in the approach toward facilities design, where single-point, “conservative” design conditions are proposed and assembled as facilities design-basis documents. This approach frequently fails to recognize the risks and uncertainties associated with oilfield developments.

In the proposed work flow, deterministic models are established to account for the dependencies between design input variables {static variables [i.e., bottomhole pressure (BHP) and bottomhole temperature (BHT)]} and the desired objective [static results (i.e., chemical- injection rate)]. In the provided example, the analyzed variables change because of subsurface and surface events with different levels of uncertainty (i.e., condensate banking, lean-gas injection, water breakthrough). Stochastic algorithms are used to create probability-distribution functions (PDFs) for all analyzed design input variables (stochastic variables). Stochastic algorithms are then applied in the deterministic model, sampling from the previously defined probability distributions. Stochastic results are assembled into insightful charts and used to analyze the most-relevant variables and correlations affecting the objective function.

Enfoque matricial para el diseño de sistemas de prestación de servicios
Authors: Davis-Castro Dina
Published: November 2017

El cambio desde un enfoque puramente funcional a uno por procesos está condicionado desde fuera y desde dentro de las organizaciones. El mundo cambia aceleradamente, y esta velocidad aumenta por décadas. Las condiciones políticas, económicas, sociales y tecnológicas en el mundo en general, y en América Latina en particular, distan mucho entre los últimos 50 años del siglo XX y los primeros 15 años del siglo XXI. Hay una estrecha relación entre la velocidad de los cambios tecnológicos y   socioeconómicos.  Esto conduce a un estado de incertidumbre que incide fuertemente sobre las formas de planificar de las organizaciones. En la medida en que los ciclos Innovación – Desarrollo se acortan, se produce un desfase entre la aparición de productos con prestaciones superiores en el mercado y la duración de bienes similares adquiridos previamente por los usuarios. Este fenómeno se manifiesta de particular forma, pues la tendencia en el comportamiento de los clientes es a la solicitud de servicios que solucionen sus necesidades más que de productos específicos. El presente ensayo analiza algunos de los fenómenos que inciden en el diseño de procesos de servicios con un enfoque matricial, resultado de investigación realizada en este ámbito.
