Standard Model Higgs Boson Combination at the Tevatron
Creators: name: Yao, Wei-Ming

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We present the recent results from combinations of searches for a standard model (SM) Higgs boson ($H$) by the CDF and D0 experiments at the Tevatron $p\bar p$ collider at $\sqrt{s}=1.96$ TeV. The data correspond to an integrated total luminosity of 8.2 (CDF) and 8.6 (D0) fb$^{-1}$. Compared to the previous Tevatron Higgs boson search combination more data have been added, additional channels have been added, and some previously used channels have been reanalyzed to gain sensitivity. No excess is observed above background expectation, and set 95% C.L. upper limits (median expected) on Higgs boson production at factors of 1.17 (1.16), 1.71 (1.16), and 0.48(0.57) times the SM predictions for Higgs bosons of mass $m_H$=115, 140, and 165 GeV/c$^2$, respectively. We exclude a standard-model Higgs boson in the mass range 156--177 GeV/c$^2$ at the 95% C.L, with an expected exclusion region 148--180 GeV/c$^2$. The absence of a Higgs boson signal also constrains some new physics such as $4^{th}$ generation models and other exotic models.

Creators: name: Webb, Sarah-Ann Katherine
Publisher: name: University of Kentucky
Year: 2016
Subjects: subject: Educational Methods

description: The purpose of this study was to teach telling time to the hour, half-hour, quarter to the hour, and to 5 min to students with austim spectrum disorder (ASD) or other developmental disabilities using video modeling (VM). Two research questions were asked: 1. Is there a functional relation between VM and increases in level and trend for telling time to the hour, half-hour, quarter hour, or 5 min for students with ASD and/or other developmental disabilities? 2. Will the use of the VM help students reach criterion on the task analytic steps for the process of telling time? A multiple probe (days) across participants design was used evaluate the effectiveness of the VM. The results showed student improvement of telling time, but no functional relation was found. The results showed improvement of telling time once System of Least Prompts was added to the VM.

description: The purpose of this research study was to provide training for peer tutors to use simultaneous prompting to increase the percentage of correct responses of sight words by students with moderate to severe disabilities. The study included four students with moderate to severe disabilities in an elementary school setting. A multiple probe (days) design across behaviors replicated across students was used to evaluate the effectiveness of the simultaneous prompting procedure used by peer tutors to teach students with moderate to severe disabilities in the general education setting. The results indicated the peers were able to reliably implement the procedures, but a functional relation was demonstrated with only one participant.

description: Excerpts from the report Introduction: European--particularly West German--as well as domestic markets are concerned with additives to foods. One of the issues raised concerns the question of biphenyl residues on American-grown citrus fruit. This report supplements previous research in giving information on how control of decay can be accomplished effectively without excessive biphenyl accumulating in the fruit. This research is part of a broad continuing program by the Agricultural Marketing Service to maintain quality and to reduce spoilage losses in farm products. The effects of temperature, storage time, carton venting, and kind of fruit on the rate of loss of biphenyl from the biphenyl pads and on the concentration of biphenyl vapor in the carton atmosphere, and the relationship of these factors to decay, sporulation, and soilage (dusting of sound fruit with spores of fungi from decaying fruit) of the fruit were determined.

description: We report on the design, fabrication, and characterization of GaN interband tunnel junction showing forward tunneling characteristics. We have achieved very high forward tunneling currents (153 mA/cm2 at 10 mV, and 17.7 A/cm2 peak current) in polarization-engineered GaN/InGaN/GaN heterojunction diodes grown by plasma assisted molecular beam epitaxy. We also report the observation of repeatable negative differential resistance in interband III-Nitride tunnel junctions, with peak-valley current ratio (PVCR) of 4 at room temperature. The forward current density achieved in this work meets the typical current drive requirements of a multi-junction solar cell.

description: We report the detection of transit timing variations (TTVs) well in excess of one hour in the Kepler multi-planet candidate system KOI 806. This system exhibits transits consistent with three separate planets -- a Super-Earth, a Jupiter, and a Saturn -- lying very nearly in a 1:2:5 resonance, respectively. We used the Kepler public data archive and observations with the Gran Telescopio de Canarias to compile the necessary photometry. For the largest candidate planet (KOI 806.02) in this system, we detected a large transit timing variation of -103.5$\pm$6.9 minutes against previously published ephemeris. We did not obtain a strong detection of a transit color signature consistent with a planet-sized object; however, we did not detect a color difference in transit depth, either. The large TTV is consistent with theoretical predictions that exoplanets in resonance can produce large transit timing variations, particularly if the orbits are eccentric. The presence of large TTVs among the bodies in this systems indicates that KOI806 is very likely to be a planetary system. This is supported by the lack of a strong color dependence in the transit depth, which would suggest a blended eclipsing binary.

description: Effective, permanent tuning of the whispering gallery modes (WGMs) of p-i-n doped GaN microdisk cavity with embedded InGaN quantum dots over one free spectral range is successfully demonstrated by irradiating the microdisks with a ultraviolet laser (380nm) in DI water. For incident laser powers between 150 and 960 nW, the tuning rate varies linearly. Etching of the top surface of the cavity is proposed as the driving force for the observed shift in WGMs, and is supported by experiments. The tuning for GaN/InGaN microdisk cavities is an important step for deterministically realizing novel nanophotonic devices for studying cavity quantum electrodynamics.

description: We present a combined experimental, numerical and theoretical investigation of the geometric scaling of the onset of a purely-elastic flow instability in a serpentine channel. Good qualitative agreement is obtained between experiments, using dilute solutions of flexible polymers in microfluidic devices, and two-dimensional numerical simulations using the UCM model. The results are confirmed by a simple theoretical analysis, based on the dimensionless criterion proposed by Pakdel-McKinley for onset of a purely-elastic instability.

description: Blue (metal-poor) globular clusters are observed to have half-light radii that are ~20% larger than their red (metal-rich) counterparts. The origin of this enhancement is not clear and differences in either the luminosity function or in the actual size of the clusters have been proposed. I analyze a set of dynamically self-consistent Monte Carlo globular cluster simulations to determine the origin of this enhancement. I find that my simulated blue clusters have larger half-light radii due to differences in the luminosity functions of metal-poor and metal-rich stars. I find that the blue clusters can also be physically larger, but only if they have a substantial number of black holes heating their central regions. In this case the difference between half-light radii is significantly larger than observed. I conclude that the observed difference in half-light radii between red and blue globular clusters is due to differences in their luminosity functions and that half-light radius is not a reliable proxy for cluster size.

Measuring uniformity in kraft digesters using flow-following sensors
Creators: name: Albadvi, Elham
Publisher: name: University of British Columbia
Year: 2010

description: Measurements of pulp variability and temperature distributions within kraft digesters have been the subject of intense interest for many years. An extensive survey carried out on the previous approaches to measure digester variability has shown that data directly taken from within the digester, during the kraft cook is scarce. Moreover, the increased size of modern digesters is believed to reduce the flow uniformity within them, increasing the risk of pulp variability and highlighting the need to collect data from within the digesters themselves. This has motivated the development of a new method for measuring digester variability: the “SmartChip”. This device is a flow-following sensor package that measures and records the temperature directly within the digester during the kraft cook. This research proposes a theoretical model to describe the heat transfer mechanisms occurring within the digester and then uses the data captured by the SmartChip to measure the digester variability. Preliminary test trials were conducted to ensure that the SmartChip could withstand the harsh environment of the kraft cook. Subsequently, multiple SmartChips were deployed in a single cook to provide insight on the temperature variability and heat transfer mechanisms occurring within the digester and these experimental results were then be compared with the predictions of the proposed model. Moreover, by taking pulp samples in the vicinity of the SmartChip sensors, the relation between nonuniformity and temperature gradients is established. The SmartChips have been tested in two laboratory batch digesters and as expected, temperature was already well-controlled within them and little variability was observed in these small-scale devices. Moreover, a good agreement is found between the model predictions and the experimental results and the model is experimentally validated, showing that the heat transfer through the digester contents is by pure advection with almost negligible thermal energy required for the heating of wood chips. These findings further suggest that the SmartChip works well under the harsh conditions of the kraft cook and future work is warranted to develop the instrument for its use at the industrial scale, where the temperature fluctuations along the digesters are more noticeable.
title: DEUTERIUM AND OXYGEN-18 DIFFUSION IN A CONFINED AQUIFER

Subjects: subject: Hydrology

description: The stable isotopes 2H and 18O, combined with noble gases and radioisotopes (e.g., 3H, 14C, 36Cl), are used to infer groundwater age and climate during recharge. Flow regimes within low-velocity flowpaths and long residence times could allow an aquitard-aquifer diffusive flux to alter isotope abundance. Consequently, the diffusion of isotopes (e.g., 14C, 2H and 18O) between aquifers and confining layers needs to be considered in such conditions. In this study, COMSOL Multiphysics was used to determine if diffusion of 18O (and 2H by proxy) from a bounding aquitard could explain observed downgradient enrichment of 2H and 18O within a regional aquifer. Using the geologic and hydraulic properties of the lower Wilcox aquifer of the Mississippi Embayment aquifer system in Missouri and Arkansas, the advection-dispersion equation was solved along a 1-D groundwater flow domain, coupled with a cross-contact aquitard-aquifer diffusive flux. Although the observed signal within the lower Wilcox was not matched, a sensitivity analysis indicated the importance of the isotope composition gradient between the aquifer and aquitard. Furthermore, groundwater velocity was suggested as a controlling influence on aquitard-aquifer exchange that could alter aquifer isotope composition.

description: The disk around the Herbig Ae star HD\,169142 was imaged and resolved at 18.8 and 24.5\,$μ$m using Subaru/COMICS. We interpret the observations using a 2D radiative transfer model and find evidence for the presence of a large gap. The MIR images trace dust that emits at the onset of the strong rise in the spectral energy distribution (SED) at 20\,$μ$m, therefore are very sensitive to the location and characteristics of the inner wall of the outer disk and its dust. We determine the location of the wall to be 23$^{+3}_{-5}$\,AU from the star. An extra component of hot dust must exist close to the star. We find that a hydrostatic optically thick inner disk does not produce enough flux in the NIR and an optically thin geometrically thick component is our solution to fit the SED. Considering the recent findings of gaps and holes in a number of Herbig Ae/Be group I disks, we suggest that such disk structures may be common in group I sources. Classification as group I should be considered a support for classification as a transitional disk, though improved imaging surveys are needed to support this speculation.

description: Microscopic structural instabilities of EuTiO3 single crystal were investigated by synchrotron x-ray diffraction. Antiferrodistortive (AFD) oxygen octahedral rotational order was observed alongside Ti derived antiferroelectric (AFE) distortions. The competition between the two instabilities is reconciled through a cooperatively modulated structure allowing both to coexist. The electric and magnetic field effect on the modulated AFD order shows that the origin of large magnetoelectric coupling is based upon the dynamic equilibrium between the AFD - antiferromagnetic interactions versus the electric polarization - ferromagnetic interactions.

It is shown that the violation of Clauser-Horne-Shimony-Holt (CHSH) inequality is necessary and sufficient for the nonlocality of two-qubit SC states, whereas the violation of the Svetlichny inequality is only a sufficient condition for the genuine nonlocality of three-qubit SC states. Furthermore, the relations among the maximum violation values, concurrence and relative entropy entanglement are discussed.

description: Emerging health concern for gaseous nitrogen oxides (NOx) emitted during surface mine blasting has prompted mining authorities in the United States to pursue new regulations. NOx is comprised of various binary compounds of nitrogen and oxygen. Nitric oxide (NO) and nitrogen dioxide (NO2) are the most prominent. Modern explosive formulations are not designed to produce NOx during properly-sustained detonations, and researchers have identified several causes through laboratory experiments; however, direct sampling of NOx following full-scale surface mine blasting has not been accomplished.  The purpose of this thesis was to demonstrate a safe, innovative method of directly quantifying NOx concentrations in a full-scale surface mining environment. A small unmanned aircraft system was used with a continuous gas monitor to sample concentrated fumes. Three flights were completed – two in the Powder River Basin. Results from a moderate NOx emission showed peak NO and NO2 concentrations of 257 ppm and 67.2 ppm, respectively. The estimated NO2 presence following a severe NOx emission was 137.3 ppm. Dispersion of the gases occurred over short distances, and novel geometric models were developed to describe emission characteristics. Overall, the direct sampling method was successful, and the data collected are new to the body of scientific knowledge.
A MODULAR ELECTRICAL POWER SYSTEM ARCHITECTURE FOR SMALL SPACECRAFT

Subjects: subject: Electrical and Electronics

description: Small satellites and CubeSats have established themselves within the aerospace community because of their low cost and high return on investment. Many CubeSats are developed in a short time frame and often leverage commercial off the shelf components for quick turnaround missions. With regard to the Electrical Power System, commercially available products typically use a centralized architecture. However, a centralized architecture is not reusable, since missions that require additional solar arrays or batteries would necessitate a redesign of the power system. With the range of CubeSat sizes and mission goals, it is obvious that a one-size-fits-all solution is not appropriate. This thesis details a reusable and scalable power system architecture applicable to a variety of missions. Reusability is achieved by using common building blocks or "modules," where the same modules can be used between missions. Scalability is achieved by not limiting the number of modules that can be connected together—more modules can be added as needed. In this system, solar arrays and battery units connect directly to a common bus, supplying an unregulated voltage to each subsystem. These subsystems then regulate the bus voltage to their individual needs. The power system also features direct energy transfer and solar-only operation.
Increasing the performance of mammalian perfusion culture system

description: Perfusion culture processes are potentially the most efficient way of producing large quantities of biopharmaceuticals. However, these processes are not the most commonly used by industry in part due to a lack of simple solutions to perfusion challenges. This thesis has investigated recombinant protein production instability, a strategy to improve low perfusion rate culture performances and the complications due to cell aggregate formation. Human embryonic kidney 293 (HEK293) cells producing recombinant human interferon-alpha2b (IFN-α2b) were investigated as a model recombinant cell line. These cells also were maintained for more than 4 weeks in batch cultures using three media with different osmolalities in order to evaluate production stability. Exposure to high osmolality (~ 375 mOsm kg­‾¹) gradually decreased the yield of IFN-α2b secreted by the viable cells. Perfusion cultures validated the batch cultures with results showing that it was not possible to maintain stable production at elevated osmolality whereas at normal osmolality (~ 300 mOsm kg­‾¹), the titer was maintained at 250 mg L­‾¹. A reduced perfusion rate strategy was explored to increase the product titer in a perfusion bioreactor using enriched media. The HEK293 cell line was found to have a growth-associated production. By increasing the bleed rate in order to increase growth, the perfusion process yielded an up to 35% increased IFN-α2b concentration. Several modified medium conditions were investigated in batch cultures to help identify the main mechanism of aggregation observed in perfusion cultures. The addition of dead cells in the batch case was found to yield cellular aggregation that was most similar to perfusion cultures. The presence of aggregation did not affect the on-line monitoring of the viable cell concentration using a permittivity signal. However, if cells in aggregates are neglected, this can result in major cell specific-rate calculation errors. The image analysis used to estimate the cellular content of aggregates was an efficient method of improving viable cell estimates and cell specific-rate analyses. Overall, advances in the methods to more efficiently monitor and operate high performance perfusion-culture processes should expand their potential to fulfill the increasing demand for recombinant protein products from biotechnology.

description: In interacting multi-component dark matter (DM) models, if the DM components are nearly degenerate in mass and the interactions between them are strong enough, the relatively heavy DM components can be converted into lighter ones at late time after the thermal decoupling. Consequently, the relic density of the lightest DM component can be considerably enhanced at late time. This may contribute to an alternative source of boost factor required to explain the positron and electron excesses reported by the recent DM indirect search experiments such as PAMELA, Fermi-LAT and HESS etc..

description: The advent of milli-kelvin scanning tunneling microscopes (STM) with inbuilt magnetic fields has opened access to the study of magnetic phenomena with atomic resolution at surfaces. In the case of single atoms adsorbed on a surface, the existence of different magnetic energy levels localized on the adsorbate is due to the breaking of the rotational invariance of the adsorbate spin by the interaction with its environment, leading to energy terms in the meV range. These structures were revealed by STM experiments in IBM Almaden in the early 2000's for atomic adsorbates on CuN surfaces. The experiments consisted in the study of the changes in conductance caused by inelastic tunnelling of electrons (IETS, Inelastic Electron Tunnelling Spectroscopy). Manganese and Iron adatoms were shown to have different magnetic anisotropies induced by the substrate. More experiments by other groups followed up, showing that magnetic excitations could be detected in a variety of systems: e.g. complex organic molecules showed that their magnetic anistropy was dependent on the molecular environment, piles of magnetic molecules showed that they interact via intermolecular exchange interaction, spin waves were excited on ferromagnetic surfaces and in Mn chains, and magnetic impurities have been analyzed on semiconductors. These experiments brought up some intriguing questions: the efficiency of magnetic excitations was very high, the excitations could or could not involve spin flip of the exciting electron and singular-like behavior was sometimes found at the excitation thresholds. These facts called for extended theoretical analysis; perturbation theories, sudden-approximation approaches and a strong coupling scheme successfully explained most of the magnetic inelastic processes. In addition, many-body approaches were also used to decipher the interplay between inelas

Decoherence and the conditions for the classical control of quantum systems

description: We find the conditions for one quantum system to function as a classical controller of another quantum system: the controller must be an open system and rapidly diagonalised in the basis of the controller variable that is coupled to the controlled system. This causes decoherence in the controlled system that can be made small if the rate of diagonalisation is fast. We give a detailed example based on the quantum optomechanical control of a mechanical resonator. The resulting equations are similar in structure to recently proposed models for consistently combining quantum and classical stochastic dynamics.

description: Acute lower respiratory tract infections (ALRI) are a substantial source of global morbidity and mortality, particularly among young children. Respiratory syncytial virus (RSV) and influenza are consistently observed to be significant drivers of this burden, but substantial gaps in our understanding remain. Greater understanding of the burden of these pathogens at the community-level, and their association with severe illness has the potential to substantially reduce the toll of ALRI, particularly among young children. In chapter 2 of this dissertation we assess the community burden of RSV and RSV-associated severe illness among Nicaraguan children aged < 2 years. In chapters 3 and 4 we explore the individual-level association between influenza and subsequent pneumonia along with characterizing the risk period for pneumonia following symptomatic influenza infection. To explore these questions we use data from the Nicaragua Influenza Birth Cohort Study (2011-2016), the Nicaraguan Pediatric Influenza Cohort Study (2011-2018), and the Nicaragua Influenza Cohort Study (2007-2010). In chapter 2 we observed the highest incidence of RSV occurred among children aged 6-11 months, while the highest incidence of RSV-associated severe ALRI was highest among those aged < 3 months and generally decreased as age increased. RSV was also associated with at least 25% of illness deaths that occurred in the cohort, highlighting its importance in reducing in infant mortality. In chapters 3 and 4 we established that influenza is associated with increased risk of subsequent pneumonia at the individual level across types and subtypes with the exception of seasonal H1N1. We also observed distinct periods of elevated pneumonia risk following influenza among children aged <2 which is suggestive of multiple etiologic pathways existing between influenza and pneumonia. By better understanding the burden and temporal dynamics of RSV and influenza we can develop more effective interventions to prevent and mitigate their effects among children.

description: We consider the finite field dependent BRST (FFBRST) transformations in the context of Hamiltonian formulation using Batalin-Fradkin-Vilkovisky method. The non-trivial Jacobian of such transformations is calculated in extended phase space. The contribution from Jacobian can be written as exponential of some local functional of fields which can be added to the effective Hamiltonian of the system. Thus, FFBRST in Hamiltonian formulation with extended phase space also connects different effective theories. We establish this result with the help of two explicit examples. We also show that the FFBRST transformations is similar to the canonical transformtaions in the sector of Lagrange multiplier and its corresponding momenta.

description: Low-energy continuous states of electron in heterosrtucture with periodically placed quantum-dot sheets are studied theoretically. The Green's function of electron is governed by the Dyson equation with the self-energy function which is determined the boundary conditions at quantum-dot sheets with weak damping in low-energy region. The parameters of superlattice formed by quantum-dot sheets are determined using of the short-range model of quantum dot. The density of states and spectral dependencies of the anisotropic absorption coefficient under mid-IR transitions from doped quantum dots into miniband states of superlattice strongly depend on dot concentration and on period of sheets. These dependencies can be used for characterization of the multi-layer structure and they determine parameters of different optoelectronic devices exploiting vertical transport of carriers through quantum-dot sheets.

description: We discuss the choice of input parameters for the renormalization of the chargino and neutralino sector in the minimal supersymmetric standard model (MSSM) in the on-shell scheme. We show that one should chose the masses of a bino-like, a wino-like and a higgsino-like state as inputs in order to avoid large corrections to the masses of the other eigenstates in this sector. We also show that schemes where the higgsino-like input state is a neutralino are more stable than those where the mass of the higgsino-like chargino is used as input. The most stable scheme uses the masses of the wino-like chargino as well as the masses of the bino- and higgsino-like neutralinos as inputs.

description: A way to probe alternative theories of gravitation is to study if they could account for the structures of the universe. We then modified the well-known Gadget-2 code to probe alternative theories of gravitation through galactic dynamics. As an application, we simulate the evolution of spiral galaxies to probe alternative theories of gravitation whose weak field limits have a Yukawa-like gravitational potential. These simulations show that galactic dynamics can be used to constrain the parameters associated with alternative theories of gravitation. It is worth stressing that the recipe given in the present study can be applied to any other alternative theory of gravitation in which the superposition principle is valid.

description: This study examines how two media sources—one Russian and one Ukrainian—portray Russia and Ukraine before, during, and after the EuroMaidan crisis in Ukraine. Russian-language texts posted between January 2013 and December 2015 on the sites Ukranews.com (a Ukrainian news outlet) and TASS.ru (Russian) were organized in a corpus of over 20,000,000 words. This study analyzes the nouns “Россия” (“Russia”) and “Украина” (“Ukraine”) according to the verbal predicates that attach to either noun. The results demonstrate predictable variation in the agency of the two entities in response to cultural events and contexts.  The analysis of the corpus data operationalizes a combined model of agency using Halliday and Matheissen’s (2004) classification of processes, shaped by the animacy of the actor, and Dik’s (1989) States of Affairs Matrix, which prioritizes the actor’s physical effect in space and time. In this study, predicates of “Russia” and “Ukraine” are given numeric scores based on the models. Then, a new method of checking the validity of these models is tested by examining other entities that take the same predicates as Russia and Ukraine. Measurements from discrete time periods reveal how the agency of both entities changed before, during, and after EuroMaidan.

description: Close-in massive planets interact with their host stars through tidal and magnetic mechanisms. In this paper, we review circumstantial evidence for star-planet interaction as revealed by the photospheric magnetic activity in some of the CoRoT planet-hosting stars, notably CoRoT-2, CoRoT-4, and CoRoT-6. The phenomena are discussed in the general framework of activity-induced features in stars accompanied by hot Jupiters. The theoretical mechanisms proposed to explain the activity enhancements possibly related with hot Jupiter are also briefly reviewed with an emphasis on the possible effects at photospheric level. The unique advantages of CoRoT and Kepler observations to test these models are pointed out.

description: RESUMEN:

Propone un modelo de mejora para la evaluación de los proyectos en el área de estudios y proyectos de la Municipalidad Provincial del Cusco, estableciendo su importancia, así mismo se propone definir el marco teórico y el ámbito conceptual en que se enmarca la problemática haciendo un diagnóstico situacional del actual modelo con el fin de diseñar y proponer un modelo mejorado que incluye un plan para su implementación. A fin de definir la problemática, se han utilizado herramientas de investigación cualitativas y cuantitativas tales como entrevistas en profundidad con expertos, análisis estadístico de los datos de las obras ejecutadas por la entidad en los últimos cuatro años. Así mismo, se han hecho uso de herramientas de análisis tales como la matriz de involucrados, análisis de causas raíz y matriz FODA. Respecto a la principales conclusiones se ha establecido que la importancia de la mejora en la evaluación de expedientes técnicos contribuirá a un uso más eficiente de los, cada vez más reducidos, recursos del estado destinados a obras públicas, mismos que provienen mayormente de la minería y de los contribuyentes. En base al marco teórico propuesto, se ha hecho un diagnóstico de la situación actual del modelo concluyéndose que existe una percibida imposición de los intereses políticos sobre los intereses técnicos, esto, junto con los sesgos cognitivos de los recursos humanos que tienen a su cargo la formulación de expedientes técnicos conlleva a eludir los controles de calidad en la formulación de los proyectos, siendo que no existe evidencia estadística para afirmar que la experiencia de los proyectistas esté relacionada con la incertidumbre en la estimación de los costos reales de las obras. Finalmente se ha diseñado un modelo mejorado para la evaluación de los proyectos en el área de estudios y proyectos de la Municipalidad Provincial del Cusco, el cual incluye medidas de mitigación de la incertidumbre en la estimación de los costos en todas las fases de formulación de un expediente técnico, con sus respectivos indicadores. Se brinda además las recomendaciones para su exitosa implementación brindándose una estimación de los beneficios económicos de hacerlo.
