description: Astronomy is entering a new era of discovery, coincident with the establishment of new facilities for observation and simulation that will routinely generate petabytes of data. While an increasing reliance on automated data analysis is anticipated, a critical role will remain for visualization-based knowledge discovery. We have investigated scientific visualization applications in astronomy through an examination of the literature published during the last two decades. We identify the two most active fields for progress - visualization of large-N particle data and spectral data cubes - discuss open areas of research, and introduce a mapping between astronomical sources of data and data representations used in general purpose visualization tools. We discuss contributions using high performance computing architectures (e.g: distributed processing and GPUs), collaborative astronomy visualization, the use of workflow systems to store metadata about visualization parameters, and the use of advanced interaction devices. We examine a number of issues that may be limiting the spread of scientific visualization research in astronomy and identify six grand challenges for scientific visualization research in the Petascale Astronomy Era.

description: Cloud Data Servers is the novel approach for providing secure service to e-business .Millions of users are surfing the Cloud for various purposes, therefore they need highly safe and persistent services. Usually hackers target particular Operating Systems or a Particular Controller. Inspiteof several ongoing researches Conventional Web Servers and its Intrusion Detection System might not be able to detect such attacks. So we implement a Cloud Data Server with Session Controller Architecture using Redundancy and Disconnected Data Access Mechanism. In this paper, we generate the hash code using MD5 algorithm. With the help of which we can circumvent even the attacks, which are undefined by traditional Systems .we implement Cloud Data Sever using Java and Hash Code backup Management using My SQL. Here we Implement AES Algorithm for providing more Security for the hash Code. The CDS using the Virtual Controller controls and monitors the Connections and modifications of the page so as to prevent malicious users from hacking the website. In the proposed approach an activity analyzer takes care of intimating the administrator about possible intrusions and the counter measures required to tackle them. The efficiency ratio of our approach is 98.21% compared with similar approaches.

description: A characterization of the optical turbulence vertical distribution and all the main integrated astroclimatic parameters derived from the CN2 and the wind speed profiles above Mt. Graham is presented. The statistic includes measurements related to 43 nights done with a Generalized Scidar (GS) used in standard configuration with a vertical resolution of ~1 km on the whole 20-22 km and with the new technique (HVR-GS) in the first kilometer. The latter achieves a resolution of ~ 20-30 m in this region of the atmosphere. Measurements done in different periods of the year permit us to provide a seasonal variation analysis of the CN2. A discretized distribution of the typical CN2 profiles useful for the Ground Layer Adaptive Optics (GLAO) simulations is provided and a specific analysis for the LBT Laser Guide Star system ARGOS case is done including the calculation of the 'gray zones' for J, H and K bands. Mt. Graham confirms to be an excellent site with median values of the seeing without dome contribution equal to 0.72", the isoplanatic angle equal to 2.5" and the wavefront coherence time equal to 4.8 msec. We provide a cumulative distribution of the percentage of turbulence developed below H* where H* is included in the (0,1 km) range. We find that 50% of the whole turbulence develops in the first 80 m from the ground. The turbulence decreasing rate is very similar to what has been observed above Mauna Kea.

description: Until  now  electric power is the major problem for rural  areas  coupled with  climate change
posing a serious problem for a world in which this  impact  is  significant  on  the  water  resource
system  and availability.  This  study  mainl y  focuses on  developing reservoir operation rule and
assessing hydropower options on Ribb irrigation dam under climate change.
The  base and  future  climate  variables  which  develop on three  periods  those are base  (1993-2006), short (2017-2030) and long (2047-2060)  with their RCP correction  with 4.5  emission
scenario  was  used  for  future  flow  simulation.  HEC-HMS  model  was  used  for  stream flow
generation  and reservoirs  inflow  estimation  using  the  bias  corrected  data. After the flow was
forecasted, the performance of  the model was assessed. Finally MODSIM model was used to
simulate  and  optimize  reservoir  operation  and  Power  production  in addition to irrigation, water
supply and environmental demand.
The projected  mean  average  maximum  temperature  increase  from  the baseline  period  by
1.1

C  and  1.8
0
C  for  short-term  and  long-term  respectivel y.  Whereas  minimum
temperature  increases  by  0.2
0
C,  and  0.56
0
C  respectively  whereas  precipitation  shows
decrease by 1.15% and 1.35% for short and long term.
The model performances result display in terms of (R
2
), (NSE) and (D) have 0.70, 0.77, and 7%
for the calibration and for validation 0.71, 0.78,  7%.  Performance  indices  (RRV)  Final result
was done Rt value greater than 85%, Rv greater than 80%, Resilience  and vulnerability average
value of 40% and 18%.  Finally  power  produce  maximum of  10496.05  KW  and  9863.028  KW
for short and long term respectively  and  minimum power of  5099.59KW and  4973.47KW  for
short and long term future scenario respectively.
Generally temperature for future scenario have an increasing trend unlikely precipitation
and flow data have decreasing value for the future. In this case the value for new power
generation decrease for future.
Finally,  Protection of the floodplain and the catchment has a double advantage of sustaining the
power supply there by protecting the catchment and increasing the reservoir volume.

IDENTIFICATION OF GROUNDWATER POTENTIAL ZONES USING GIS AND  REMOTE SENSING: THE CASE OF MEGECH WATERSHED, ETHIOPIA
Creators: name: KIBRIT GEDAM BERHANU
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Groundwater is one  of  the water resources which plays an important role in water supply in
many countries including Ethiopia. Identifying  and delineating the groundwater potential
zones is very  important for development plans, policies and sustainable utilization of the
groundwater resources  in the area of interest. However, there were only limited studies
conducted on groundwater potential of the Megech watershed. This study is mainly aimed to
identify and map the groundwater potential zones of Megech watershed.  A total of nine
thematic layers including geology, lineament density, slope, geomorphology, soil, LULC,
rainfall, drainage density and elevation were used  to map the groundwater potential zones of
Megech watershed  in GIS environment.  Weights and rates were assigned for each thematic
layer and  for  each thematic layer  classes  respectively  using the PriEsT AHP tool. ArcGIS
overlay analysis was conducted to obtain the groundwater potential  map. The percentage of
influence to the output map of the study area in view of groundwater potential was computed
using PriEsT software package having geology/lithology 30%, lineament density 23%, slope
15%, geomorphology 10%, soil 7%, LULC 6%, rainfall 4%, drainage density 3% and finally
elevation 2%.  The first four thematic layers (geology, lineament density,  slope  and
geomorphology) were found to be the dominant factors as portrayed in the map removal
analysis. There were three groundwater potential zones identified and mapped in the study
area namely low, moderate and high.  The qualitative results were also compared with an
independent set  of  79  groundwater point data to validate the results. The validation analysis
showed  75%  agreement  between the  groundwater point data classes  and  the  groundwater
potential zones identified.

description: We present the observed-frame optical, near- and mid-infrared properties of X-ray selected AGN in the Lockman Hole. Using a likelihood ratio method on optical, near-infrared or mid-infrared catalogues, we assigned counterparts to 401 out of the 409 X-ray sources of the XMM-Newton catalogue. Accurate photometry was collected for all the sources from U to 24um. We used X-ray and optical criteria to remove any normal galaxies, galactic stars, or X-ray clusters among them and studied the multi-wavelength properties of the remaining 377 AGN. We used a mid-IR colour-colour selection to understand the AGN contribution to the optical and infrared emission. Using this selection, we identified different behaviours of AGN-dominated and host-dominated sources in X-ray-optical-infrared colour-colour diagrams. More specifically, the AGN dominated sources show a clear trend in the f_x/f_R vs. R-K and f_24um/f_R vs. R-K diagrams, while the hosts follow the behaviour of non X-ray detected galaxies. In the optical-near-infrared colour-magnitude diagram we see that the known trend of redder objects being more obscured in X-rays is stronger for AGN-dominated than for host-dominated systems. This is an indication that the trend is more related to the AGN contaminating the overall colours than any evolutionary effects. Finally, we find that a significant fraction (~30%) of the reddest AGN are not obscured in X-rays.

RESERVOIR PERFORMANCE UNDER CLIMATE  CHANGE ON MEGECH WATERSHED
Creators: name: HELINA FEREDE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Now a  days the sign of climate change and its impact is revealing on different natural and  man-made systems, in one or other ways. Accordingly, this impact is significant on the water resource
system. This study mainly deals with assessment of the  reservoir performance under  climate
change  impact on the Megech reservoir which is found in  Lake Tana Sub-Basin, using the
reliability, resilience and vulnerability indices.
To evaluate the impact of climate change, climate change scenario of evapotranspiration and
precipitation were developed for three period  (base, short term and long term)  using output of
CMIP5 with RCP for RCP4.5 emission scenarios and they are used to develop the future climate
change scenario. A hydrological model, HBV, was used in order to simulate the current and future
inflow volume to the reservoirs. The performances of the model were assessed through calibration
and validation  process and the  result  shows  NSE 0.72 during calibration and 0.69 during validation
at the gauge station.
The projected future climate variable shows an increasing trend .Tmax  0.23
o
c and 2.73
o
cin short
and long term respectively and Tmin 1.68
o
c and 2.13
o
c in short and long term respectively and but
precipitation  also  shows  decreasing  by 0.84% and 1.2% in short and long term respectively.
Relative to the current condition, the average annual open water evaporation for Megech reservoir
will  increase by  1.01% and  1.03% in  short  and  long  term  respectively.  Relative to the current
condition, the simulated future period average annual inflow volume shows a decrease of 1.15%
and 1.58 % in the period of 2021 -2030 and 2061-2070 respectively from the base period.
On average,  the time based reliability of Megech reservoir shows a value of above 90  %. However,
the resilience  shows value less than 50%  in the two  periods. This shows that, the reservoir needs
long time to  recover itself from failing to meet the demand. The dimensionless vulnerability,  below
50% in all period. This Shows that the Reservoir have no shortage of Flow to meet the Demand in
all periods.
A reservoir simulation model, MODSIM, was used to simulate the amount of release potential of
the reservoirs and to determine the reservoirs operation rule curve. The future period average
annual Release  will decrease  by  1.2% and 1.19% for both short and long term in comparison to
the base period.
REAL TIME OPERATION OF MULTI-PURPOSE RESERVOIR  (THE CASE OF GENALE DAWA DAM-3)
Creators: name: ABEBAW BELAYNEH ZELALEM
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Reservoir operation has become a  major focus of water resources planning and
management. Traditionally, reservoir operation is based on heuristic procedures, embracing
rule curves and, to a certain extent, subjective  judgements by the operator. Water use
involves a large number of stakeholders with different objectives, and real time operation
is expected to provide balanced solutions between often conflicting objectives. The study
area is the Genale Dawa dam3 catchment situated at the Genale Dawa River Basin in
Ethiopia. The objective of this study is to develop real time operation of multi-purpose
reservoirs and to evaluate suitability of GD-3 sub-basin for surface irrigation development.
In this study, CMORPH satellite rainfall product was used for streamflow forecasting using
Artificial Neural Network (ANN) model. Real-time operation was performed taking real-
time and forecast information about reservoir levels, reservoir inflows and water demands
into account using MODSIM model. The result shows that the average energy generated
by GD-3 plant is  1,962.24GWh/yr,  which  is greater than the average energy in the
feasibility study for GD-3 hydropower plant, 1640.0 GWh/yr by an amount  of
322.24GWh/yr and annual volume of water about 3648.7 Mm3
  will be released for
downstream water requirement through the controlled outlets. This volume of water has the
capacity to use for irrigation since the suitability model revealed that about  55.83%
(136138.2ha) of lands in the sub basin were in the range of highly suitable to marginally
suitable for surface irrigation development.

description: Engaged learning projects can effectively complement Extension programming goals and course learning objectives that enrich the outcomes for both components. A cooperative business management class at Cornell University provides an evaluation of the fundamental principles, structure, finance, and governance associated with the cooperative business model. In so doing, students analyze contemporary issues facing modern cooperatives. In collaboration with extension programming surrounding cooperative enterprises, contemporary issues are emphasized through projects with actual cooperative businesses. Cooperatives have included farmer-owned, customer-owned, and worker-owned businesses. Students benefit from applying principles learned in class, while cooperatives benefit from the fresh, new perspectives they receive from people outside their organization. Both value the highly interactive nature of this engagement and to which work plans and expected deliverables can and often do change throughout the course of the projects. This paper synthesizes the opportunities and obstacles associated with developing and administering engaged learning projects from the learned experiences of the class instructor, professional Extension staff, and cooperative industry clients. Recommended best practices are elucidated to better inform faculty interested in implementing this dynamic approach to extension and classroom education.
IRRIGATION RESERVOIR OPERATIONAL PLANNING FOR HYDROPOWER DEVELOPMENT: THE CASE OF  GIDABO RESERVOIR, ETHIOPIA
Creators: name: MICHAEL BIRHANU GEDO
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Electrical energy is an integral component of the overall development of any nation. Most
rural populace does not have access to electricity and the shortages of electric energy
production especially in small rural areas hinder the development of rural livelihood. This
study primarily intends to undertake only a rapid technical assessment that provides some
basic information that essentially helps in making unbiased technical decision on the viability
of the proposed energy production from Gidabo dam which had not been planned or designed
with the inclusion of a hydropower scheme.
The conceptual rainfall runoff model chosen for this study was HBV-light (Beta Version).
The model was applied to simulate flow at dam site, using split record evaluation, involving
the calibration and verification periods (about 60% for calibration and 40% for verification).
During calibration period, the optimized parameters which give good performance result
were determined (Reff=0.74). These optimized parameters are validated. Performance of the
model in the validation period was 0.68. The study also presents the work of reservoir
operation and hydropower potential estimation using HEC-ResSim Model for the better
operation and management of Gidabo  reservoir. The study attempts to examine the
complexities in reservoir operation and prepare an optimum operation plan or release rule for
Gidabo  reservoir. The main objectives are simulating the optimal operation of Gidabo
reservoir for the proposed water demand activities by accurately determining the reservoir
inflow using HEC-ResSim model and estimate the hydropower potential that can be
produced while meeting the current demands at a specified level of reliability. In the
simulation of  Gidabo reservoir, the reservoir physical characteristics, operational
characteristics, monthly water demands and the hydrological inputs to the reservoir (Net
evaporation, surface inflow) were collected and configured. This study developed optimum
operating rules for Gidabo reservoir by using the application of HEC-ResSim model and
estimates the optimal hydropower production regarding to storage (m3), reservoir level (m),
and inflow-outflow relations of the reservoir. Based on simulation result the study evaluated
the hydropower potentials of the Gidabo reservoir and found that the Gidabo reservoir can
potentially generate on daily base 2.3MW and 0.2MW if the Gidabo reservoir water level is respectively placed at 1215.9m and 1212.1m above mean sea level. These levels represent
the upper and the lower limits at which the proposed hydropower scheme can sufficiently
release water from  Gidabo  reservoir to conjunctively meet the water  demands for the
proposed hydropower and designed irrigation purposes.

m.  Data  collected  during  the  study  were:  plant  height,  soil  moisture  content  of  the  soil,
irrigation depth and  biomass yield. To determine the ETc of the fodder crops, water balance
method  was  used.  Kc  of  desho  grass  and  oats  &  vetch  fodder  crops  were  computed  from
measured  ETc  and  ETo  which  was  calculated  from  weather  data.  Seasonal  ETc  of  desho
grass  and  oats  and  vetch  was  206  and  186  mm,  respectively.  K
c  values  of  desho  grass  at
early, vegetative,  mid and late stages were  0.4, 0.71, 0.89, and 0.72 respectively whereas for
oats  &  vetch was 0.29, 0.89, 1.01, and 0.71,  respectively.  Evaluation of WFD was tested by
one way ANOVA software at a significant level of (p<=0.05).  At the mid and late stages of
Desho  grass,  the plant height  under  WFD treatment was higher than the  local practices  by
28% and 23% respectively whereas the plant height of  oats and vetch under  WFD treatment
was higher than the  local practices  at the mid and late season by 23% and 9%  respectively.
The  biomass  of desho grass  and oats  and vetch at the WFD treatment  was  higher than the
local practices  by 19% and 21% respectively. The irrigation water productivity difference of
desho grass and oats and vetch under  WFD treatment was higher than the local practices by
13.5  %  and 24% respectively.  In conclusion,  WFD  was better to save time, to have better
yield, and to use the water resource effectively and efficiently.

ASSESSMENT OF HYDROLOGIC IMPACTS OF LAND USE CHANGE IN  KULFO RIVER WATERSHED USING SWAT MODEL
Creators: name: Tilahun Wankie
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: ABSTRACT
Land  use  and  land  cover  changes  in  Kulfo  River  watershed  experiences  a  lot  of  human
disturbances due to agricultural expansion, and increasing urban demand for charcoal, fuel wood
and timber; resulting in forest and land degradation. This in turn altered the hydrologic responses
of the catchment. This study was conducted to assess the hydrological response of land use/cover
change on Kulfo River flows.  In this study SWAT model was selected  as  it applies distributed
hydrologic  model  where  various  spatial  parameters  could  be  used  and  runoff  is  simulated  at
required  scale.  Spatial  data  (land  use,  DEM  and  soil)  and  meteorological  data  were  obtained
from  USGS  Satellite  image,  Ministries  of  Water  Resources,  Irrigation  and  Energy,  National
Meteorology  agency  respectively.  SWAT  model  was  used  to  simulate  stream-flow  for  land
use/land  cover  for  the  year  1985,  1995  and  2005  to  determine  the  impact  of  land  use/cover
change on Kulfo stream flow. Land use maps of 1985, 1995 and 2005 were derived from satellite
images  processed  using  ERDAS  Imagine  9.1  software.  The  model  is  calibrated  and  validated
using  historical  flow  data.  Land  cover  change  analysis  has  shown  an  increment  in  the
proportional of the Agricultural land from  11.9%  to  14.39%,  Bare land from  25.8%  to  14.14%,
Forest  from  16%  to  12.43%.  Water  body,  remain  stable,  however,  Shrub  land  increased  from
29.28%  to  36.82%  in  between  1985  to  2005.  Sensitivity  analysis  has  shown  that  the  curve
number is the most sensitive parameter that affects the hydrology of the watershed. The models
were calibrated using flow data from the 1989 to 2001 and validate from 2002 to 2008. The R
2
and Nash-  Sutcliffe  Efficient  (NSE) value for the watershed were 0.78 and 0.93 for calibration
and  0.80  and  0.78  for  the  validation  respectively.  It  has  been  concluded  that  LULC  highly
affected the runoff process in the watershed.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The  main  aim  of  this  thesis  is  to  study  the  existing  and  future  water  availability  under
climate change in upper awash sub-basin which contributes significant flow to Koka dam
and  also  on  water  allocation  of  the  existing  and  planned  water  resource  projects
(irrigation, hydropower, industries, livestock etc.) in the upper awash.
HEC-HMS  hydrologic  model  is  used  to  assess  the  water  availability  of  sub-basin.  The
future  stream  flow  forecasted  in  the  sub-basin  were  simulated  by  the  dynamically
downscaled A1B  scenarios known as RCP 4.5 (Representative Concentration Pathways)
has been adopted from CORDEX archive and bias correction were done by using power
transformation  equation  before  using  in  HEC-HMS  model.  The  result  of  future  water
availability from 2006 to 2031 in sub-basin was found to be nearly 1001 MMC.
The  Water  Evaluation  and  Planning  System  (WEAP)  model  is  used  for  optimal  water
allocation for existing and proposed water resource projects using the monthly based data
in  both  the  demand  side  and  supply  sides  and  by  priority  setting  situation  for  demand
sites.  The  reference  period  used  for  the  simulation  ranges  from  1981-2009  while  the
future scenario period ranges from 2006-2031.
The  monthly  water  requirement  for  each  crop  mainly  sugarcane  is  estimated  using
Cropwat 8.0 software by adopting Penman-Monteith approach and crop coefficient of the
crop. The existing irrigation  projects  were  around  95,155 ha while in the future scenario
period  the  irrigable  land  expected  to  increase  by  21,103  ha.  According  to  reference
scenario  the  downstream  irrigation  project  shows  the  highest  supplied  volume  about
479.4  MCM annually. According to future scenario period the UV1 and UV3 irrigation
projects  shows  increasing  water  demand  from  the  refinance  period  by  about  203.5  and
357.5  MCM  annually  due  to  expansion  of  the  irrigation  projects.  The  annual  water
demand and supplied for the reference period found to be 1716.3 MCM while the demand
increases to 1953.3 MCM for the future scenario with no unmet demand.

description: Large  irrigation  systems   have  their  own  identity  and  have  a  very  important  role
in  economic development  of  many  parts  of  the  world. Therefore the aim of this study
was to assess the performance of selected command blocks of koga dam and irrigation
project for comparing their level of performance using minimum set of performance
indicators. The study was also met its objective by collected and analyzed secondary and
primary data of climatic, soil, Crop and water delivery or water use.
Irrigation water applied on irrigable areas within the blocks was insufficient, too much or
not  the  recommended  water  quantity.  Therefore  it  was  essential  to  revise  irrigation
schedule and the ways in which we managed water application uniformities, efficiencies
and conditions of irrigation and drainage canals. The results of water delivery  and
agricultural  performance indicators showed ranges of annual relative water supplied from
0.60 to 6.75; annual relative irrigation water supplied from 0.48 to 7.53; reliability of
water delivered from 0.57 to 0.84; Adequacy 0.9 to 3.00 ; crop production from 3.8
to13.5 tons/ha; output per unit water irrigation water supplied from 0.32 to 3.8 kg/m
3
with
irrigation  ratio    ranged  0,87  to  0.99.Therefore  there  should  be  strong  argument  for
ensuring water delivery of the main and secondary canals made as reliable as possible
thereby enhancing the management capacity of farmers to utilize irrigation water  and
land according to their own objectives at farm level.

description: A vortex crossing a thin-film superconducting strip from one edge to the other, perpendicular to the bias current, is the dominant mechanism of dissipation for films of thickness d on the order of the coherence length XI; and of width w much narrower than the Pearl length LAMBDA >> w >> XI. At high bias currents, I* < I < Ic, the heat released by the crossing of a single vortex suffices to create a belt-like normal-state region across the strip, resulting in a detectable voltage pulse. Here Ic is the critical current at which the energy barrier vanishes for a single vortex crossing. The belt forms along the vortex path and causes a transition of the entire strip into the normal state. We estimate I* to be roughly Ic/3. Further, we argue that such "hot" vortex crossings are the origin of dark counts in photon detectors, which operate in the regime of metastable superconductivity at currents between I* and Ic. We estimate the rate of vortex crossings and compare it with recent experimental data for dark counts. For currents below I*, i.e., in the stable superconducting but resistive regime, we estimate the amplitude and duration of voltage pulses induced by a single vortex crossing.

Nonlinear force-free reconstruction of the global solar magnetic field: methodology

description: We present a novel numerical method that allows the calculation of nonlinear force-free magnetostatic solutions above a boundary surface on which only the distribution of the normal magnetic field component is given. The method relies on the theory of force-free electrodynamics and applies directly to the reconstruction of the solar coronal magnetic field for a given distribution of the photospheric radial field component. The method works as follows: we start with any initial magnetostatic global field configuration (e.g. zero, dipole), and along the boundary surface we create an evolving distribution of tangential (horizontal) electric fields that, via Faraday's equation, give rise to a respective normal field distribution approaching asymptotically the target distribution. At the same time, these electric fields are used as boundary condition to numerically evolve the resulting electromagnetic field above the boundary surface, modelled as a thin ideal plasma with non-reflecting, perfectly absorbing outer boundaries. The simulation relaxes to a nonlinear force-free configuration that satisfies the given normal field distribution on the boundary. This is different from existing methods relying on a fixed boundary condition - the boundary evolves toward the a priori given one, at the same time evolving the three-dimensional field solution above it. Moreover, this is the first time a nonlinear force-free solution is reached by using only the normal field component on the boundary. This solution is not unique, but depends on the initial magnetic field configuration and on the evolutionary course along the boundary surface. To our knowledge, this is the first time that the formalism of force-free electrodynamics, used very successfully in other astrophysical contexts, is applied to the global solar magnetic field.

description: Bayesian networks are probabilistic graphical models widely employed to understand dependencies in high-dimensional data, and even to facilitate causal discovery. Learning the underlying network structure, which is encoded as a directed acyclic graph (DAG) is highly challenging mainly due to the vast number of possible networks in combination with the acyclicity constraint. Efforts have focused on two fronts: constraint-based methods that perform conditional independence tests to exclude edges and score and search approaches which explore the DAG space with greedy or MCMC schemes. Here, we synthesize these two fields in a novel hybrid method which reduces the complexity of MCMC approaches to that of a constraint-based method. Individual steps in the MCMC scheme only require simple table lookups so that very long chains can be efficiently obtained. Furthermore, the scheme includes an iterative procedure to correct for errors from the conditional independence tests. The algorithm offers markedly superior performance to alternatives, particularly because it also offers the possibility to sample DAGs from their posterior distribution, enabling full Bayesian model averaging for much larger Bayesian networks. Supplementary materials for this article are available online.

description: We prove in this paper that there exists some infinitary rational relations which are Sigma^0_3-complete Borel sets and some others which are Pi^0_3-complete. This implies that there exists some infinitary rational relations which are Delta^0_4-sets but not (Sigma^0_3U Pi^0_3)-sets. These results give additional answers to questions of Simonnet and of Lescow and Thomas.
