Year: 2015

description: Nowadays the sign of climate change and its impact is revealing on different natural and man-made
systems,  in  one  or  other  ways.  This  impact  is  significant  on  water  resource  systems.  Therefore
impact of climate change on different sectors need to be evaluated in order to understand the extent
of  the  impact  and  to  propose  possible  adaptation  measures  to  reduce  the  expected  future
consequences. This study mainly deals with hydrological impact of climate change impact on Koga
reservoir operation which is found in Upper Blue Nile Basin,  using the reliability, resilience and
vulnerability indices. The hydrological models, HBV were utilized  to simulate the  water balance
inflow of the reservoir. The model result shows good performance with R
2
=0.853 and NSE=0.744.
The projected future climate variables has two future time series (2031-2040 and 2091-2100), in
which the annual percentage change of PET with respect to the base period (1991-2000) ranges
between  +4.68%  and  +10.30%.  The  annual  precipitation  shows  reductions  which  range  between
1.69 to 5.93% with in the two time series and annual runoff shows a 14.04% reduction in the first
time  series  and  9.75%  on  the  second  time  series.  Two  seasons  (FMAM  and  JJAS)  shows  high
reduction  of  runoff  in  both  future  time  series  (-16.52%  to  -26.76%)  and  (-13.84%  to-25.51%)
respectively.
The reservoir simulation model,HEC-ResSim was used for release and rule curve development and
in general it is observed that no significant changes on release and rule curve for future condition.
From  reservoirs  operational  performance  indices  on  average  it  was  generally  observed  that  the
reliability index (time based and volumetric basis) in the Koga reservoirs for all climate scenarios
reveals above 80%, hence the reservoir has high capability to meet the required target demand in
the next century.  The resilience of the reservoir on average has an index of less than 50%  for all
climate scenarios as result the reservoir will not able to recover rapidly from failure to safe state.
The vulnerability of the reservoir has an index of less than 50% for all climate scenarios hence the
reservoir has no shortage of flow to meet the demand in the next century.
Finally  from results of performance indices the Koga reservoir has very good potential to irrigate
the required area under future climatic condition.
Development of an instantaneous frequency estimation pipeline for compressional and shear wave arrival picking : application to quarry blast data

description: Many seismology applications such as earthquake hypocenter determination, source mechanism analysis, and hydrocarbon reservoir imaging, require accurate compressional and shear wave arrival time picking. Traditionally different seismological organizations have relied on human expert manual picking of seismic wave arrival and labeling. However as the number of seismic stations around the world rapidly grows, the need for automatic phase picking algorithms is increasing and requires the employment of large datasets. These algorithms need to distinguish between the different seismic phases, and accurately measure their onset. This thesis proposes a seismic signal processing pipeline application for automatic time picking of seismic compression waves (P) and shear waves (S). The algorithm picking accuracy is evaluated on quarry blasts seismic traces, and compared to manual expert picking. The proposed pipeline consists of three main segments: The data pre-processing segment focuses on Empirical Mode Decomposition (EMD) as a method of deconstructing multicomponent signals into monocomponent signals, followed by the Singular Spectral Analysis (SSA) method as a denoising filter. The data processing segment computes the instantaneous frequency (IF) using weighted least squares and Tychonov regularization with quadratic constraints. The data post-processing segment uses seismic signal IF estimation to pick the compressional and shear waves arrival times.

description: In supersymmetric quantum mechanics the emergence of a singularity may lead to the breakdown of isospectrality between partner potentials. One of the regularization recipes is based on a topologically nontrivial, multisheeted complex deformations of the line of coordinate $x$ giving the so called quantum toboggan models (QTM). The consistent theoretical background of this recipe is briefly reviewed. Then, certain supersymmetric QTM pairs are shown exceptional and reducible to doublets of non-singular ordinary differential equations a.k.a. Sturm-Schrödinger equations containing a weighted energy $E\to EW(x)$ and living in single complex plane.

description: This work is devoted to the issue of partitioning the 10 kV distribution network using smart reclosers, which is an important solution for improving the reliability of power supply and reducing the damage to distribution grid companies from undersupply of electricity. A study of the feasibility of installing reclosers in a 10 kV distribution network was conducted. The optimal number of reclosers was identified, the installation location was selected, and the distribution network operation modes were analyzed. Installation of the recloser allowed to reduce the number and duration of emergency shutdowns, to reduce the damage caused by power failure, which proves the feasibility of using this equipment.
Analyzing the Impact of Land use and Climate changes on Soil erosion and  Stream flow in the Upper Gilgel Abbay Catchment, Ethiopia.
Creators: name: Kirubel Mekonnen Gebreyesus

description: Land use and climate are two main factors directly influencing the hydrological processes of
the  catchment.  Hence,  it  is  crucial  to  know  the  combined  effects  of  land  use and  climate
change  on  catchment  hydrology  for  effective  land  use  planning  and  water  resource
management. The Soil and Water Assessment Tool (SWAT) model was used to examine the
impact of various land use and climate change scenarios on soil erosion and stream flow in
the Upper Gilgel Abbay Catchment. The base reference hydrologic response units  (HRUs)
for  land  cover  was  modified  to  reflect  the  trend,  conservation  and  plan  based  land  use
scenario definitions and projected to the foreseeable future, 2011-2025.These three plausible
land  use  scenarios  were  also  integrated  with 2011-2025  meteorological  data  from climate
local  model  simulation  and  their  combined  effects  were  evaluated  and  quantified  by
comparing SWAT outputs to baseline run (1996-2010).
The combined effect of trend based land use and climate change scenario can increase the
average annual flow by 5.2% and sediment yield by 29% and would affect soil erosion and
stream flow more significantly than other scenario conditions. The trend based land use and
climate change alone will increase the flow by 1.7% and 4.7%, and sediment yield by 17.2%
and 2.4 %, respectively. On the other hand, the implementation of both plan and conservation
based  land  uses  will  reduce the  increased  stream  flow  and  sediment  yield  caused  by  the
projected climate change scenario; and can be used as an adaptation option for the projected
climate change impacts .In general, in all scenario simulation, the flow is more sensitive to
climate changes than land use changes however ;soil erosion is likely to be more affected by
land use changes than climate changes even if the combined effects of land use and climate
change  would  considerably  alters  the  hydrological  behavior  of Upper  Gilgel  Abbay
catchment during 2011-2025. Therefore; in the planning of adaptation strategies to climate
and  land  use  change  impacts  on  catchment  hydrology, it  is  necessary  to  consider  the
combined  effects  of  climate  and  land  use  change  rather  than  to  simulate  their  impacts
separately.

description: An elementary Ising spin model is proposed for demonstrating cascading failures (break-downs, blackouts, collapses, avalanches, ...) that can occur in realistic networks for distribution and delivery by suppliers to consumers. A ferromagnetic Hamiltonian with quenched random fields results from policies that maximize the gap between demand and delivery. Such policies can arise in a competitive market where firms artificially create new demand, or in a solidary environment where too high a demand cannot reasonably be met. Network failure in the context of a policy of solidarity is possible when an initially active state becomes metastable and decays to a stable inactive state. We explore the characteristics of the demand and delivery, as well as the topological properties, which make the distribution network susceptible of failure. An effective temperature is defined, which governs the strength of the activity fluctuations which can induce a collapse. Numerical results, obtained by Monte Carlo simulations of the model on (mainly) scale-free networks, are supplemented with analytic mean-field approximations to the geometrical random field fluctuations and the thermal spin fluctuations. The role of hubs versus poorly connected nodes in initiating the breakdown of network activity is illustrated and related to model parameters.

We fit the color-octet (CO) long-distance matrix elements , and to the transverse momentum (p_T) distributions measured by CDF at Fermilab Tevatron and by H1 at DESY HERA and show that they also successfully describe the p_T distributions from PHENIX at BNL RHIC and CMS at the CERN LHC as well as the photon-proton c.m. energy and (with worse agreement) the inelasticity distributions from H1. In all experiments, the CO processes are shown to be indispensable.

The impact of lifestyle on the reproductive, metabolic, and psychological well-being of women with polycystic ovary syndrome (PCOS)
Creators: name: Cutler, Dylan
Publisher: name: University of British Columbia

description: Introduction: Polycystic ovary syndrome (PCOS) affects the reproductive, metabolic, and psychological health of 6 to 18% of women worldwide. The impact of lifestyle is poorly understood in research and practice. This dissertation aims to elucidate how dietary intake, physical activity, and psychological well-being relate to the array of symptoms and characteristics of PCOS. Methods: Women diagnosed with PCOS were compared to women without PCOS with subfertility in four observational studies. Data collected included: dietary intake, physical activity, psychological well-being symptoms (depression, anxiety, stress, and quality of life), anthropometrics, metabolic and reproductive hormonal assays. A protocol for a randomized controlled trial involving a lifestyle intervention is presented. Results: Women with PCOS had similar caloric intake and physical activity as women without PCOS, despite being more overweight (P < 0.001). In women with PCOS, those with insulin resistance (IR) consumed less fiber (P < 0.05), a greater glycemic load (P = 0.03) and less magnesium (P < 0.05) than without IR. Fiber intake was negatively correlated with IR (rho = -0.35, P < 0.005), fasting insulin (rho = -0.37, P < 0.005), glucose tolerance (rho = -0.23, P < 0.05), testosterone (rho = -0.35, P < 0.005), and dehydroepiandrosterone sulfate (rho = -0.27, P = 0.02). Magnesium intake was negatively correlated with IR (rho = -0.32, P < 0.01), C-reactive protein (rho = -0.47, P < 0.001), and testosterone (rho = -0.30, P < 0.01), but positively correlated with HDL cholesterol (rho = 0.29, P = 0.01). Symptoms of anxiety were significantly higher in women with PCOS, particularly those with hyperandrogenism (P < 0.01). In women with PCOS and increased depressive symptoms, vitamin D intake was significantly decreased (P < 0.02). Conclusions: While caloric intake of women with PCOS could not explain obesity, increasing fiber and magnesium intakes may reduce IR, hyperandrogenemia, and dyslipidemia. Women with PCOS, particularly hyperandrogenic phenotypes, experience increased symptoms of anxiety potentially related to hirsutism, which challenges societal expectations of women’s appearance. A lifestyle focused on a high fiber, low glycemic diet, supplementation, physical activity, and managing emotional distress may improve some symptoms of PCOS.

description: Investigations into the heterogeneous pinning properties of the vortex state created by partially nano-patterning single crystals of 2H-NbSe2 reveal an atypical magnetization response which is significantly drive dependent. Analysis of the magnetization response shows non-monotonic behavior of the magnetization relaxation rate with varying magnetic field sweep rate. With all the patterned pinning centers saturated with vortices, we find that the pinning force experienced by the vortices continues to increase with increasing drive. Our studies reveal an unconventional dynamic weak to strong pinning crossover where the flow of the vortex state appears to be hindered or jammed as it is driven harder through the interstitial voids in the patterned pinning lattice.

description: From radiation magnetohydrodynamic simulations of the solar atmosphere we find a new mechanism for the excitation of longitudinal slow modes within magnetic flux concentrations. We find that the convective downdrafts in the immediate surroundings of magnetic elements are responsible for the excitation of slow modes. The coupling between the external downdraft and the plasma motion internal to the flux concentration is mediated by the inertial forces of the downdraft that act on the magnetic flux concentration. These forces, in conjunction with the downward movement, pump the internal atmosphere in the downward direction, which entails a fast downdraft in the photospheric and chromospheric layers of the magnetic element. Subsequent to the transient pumping phase, the atmosphere rebounds, causing a slow mode traveling along the magnetic flux concentration in the upward direction. It develops into a shock wave in chromospheric heights, possibly capable of producing some kind of dynamic fibril. We propose an observational detection of this process.

description: In a pilot project to study the relationship between star formation and molecular gas properties in nearby normal early-type galaxies, we used the IRAM 30m telescope to observe the 13CO(J=1-0), 13CO(J=2-1), HCN(J=1-0) and HCO+(J=1-0) line emission in the four galaxies of the SAURON sample with the strongest 12CO emission. We report the detection of 13CO emission in all four SAURON sources and HCN emission in three sources, while no HCO+ emission was found to our detection limits in any of the four galaxies. We find that the 13CO/12CO ratios of three SAURON galaxies are somewhat higher than those in galaxies of different Hubble types. The HCN/12CO and HCN/13CO ratios of all four SAURON galaxies resemble those of nearby Seyfert and dwarf galaxies with normal star formation rates, rather than those of starburst galaxies. The HCN/HCO+ ratio is found to be relatively high (i.e., >1) in the three SAURON galaxies with detected HCN emission, mimicking the behaviour in other star-forming galaxies but being higher than in starburst galaxies. When compared to most galaxies, it thus appears that 13CO is enhanced (relative to 12CO) in three out of four SAURON galaxies and HCO+ is weak (relative to HCN) in three out of three galaxies. All three galaxies detected in HCN follow the standard HCN-infrared luminosity and dense gas fraction-star formation efficiency correlations. As already suggested by 12CO observations, when traced by infrared radiation, star formation in the three SAURON galaxies thus appears to follow the same physical laws as in galaxies of different Hubble types. The star formation rate and fraction of dense molecular gas however do not reach the high values found in nearby starburst galaxies, but rather resemble those of nearby normal star-forming galaxies.

description: We propose a theoretical scheme to generate a controllable and switchable coupling between two double-quantum-dot (DQD) spin qubits by using a transmission line resonator (TLR) as a bus system. We study dynamical behaviors of quantum correlations described by entanglement correlation (EC) and discord correlation (DC) between two DQD spin qubits when the two spin qubits and the TLR are initially prepared in $X$-type quantum states and a coherent state, respectively. We demonstrate that in the EC death regions there exist DC stationary states in which the stable DC amplification or degradation can be generated during the dynamical evolution. It is shown that these DC stationary states can be controlled by initial-state parameters, the coupling, and detuning between qubits and the TLR. We reveal the full synchronization and anti-synchronization phenomena in the EC and DC time evolution, and show that the EC and DC synchronization and anti-synchronization depends on the initial-state parameters of the two DQD spin qubits. These results shed new light on dynamics of quantum correlations.

description: This work is devoted to a review of swarm intelligence algorithms, specifically those that have received their inspiration from nature - from the behavior of birds, bees, ants, bats, flocks of wolves and fireflies. The origin and application of each of them is distinguished. Then a comparative analysis of the four algorithms is made on the twelve unimodal functions. Based on the results of the experiment, the algorithm that has shown itself to be the best on average is examined, and its principle of operation and implementation in the MatLab language are considered.
HYDROLOGICAL DROUGHT ANALYSIS UNDER CLIMATE CHANGE  SCENARIO FOR UPPER BLUE NILE BASIN, ETHIOPIA (CASE STUDY OF PROPOSED OUTLET ON KESSIE SUBBASIN]
Creators: name: ANIMIE AYEHU ABEBE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: This paper revises the hydrological drought under future climate change scenarios. The most part
of the study area is disposed to a drought; shared sources of water such as reservoirs, rivers and
groundwater for wells are in danger of running dry. An analysis of drought in Kessie basin based
on daily data from 1983-2012, in 11 stations over the study area  were  presented using SWAT
model. General Circulation Models (GCMs) which are considered as the most important tools for
estimating  future  climate  change  scenarios  operate  on  coarse  resolutions.  Climate  change
scenarios  of  precipitation  and  temperature  were  developed  at  Bahir  Dar,  Debre  Markos  and
Motta stations of the Basin  for three periods namely; 2011-2040, 2041-2070 and 2071-2099 and
their  respective  changes  were  determined  as  deltas  (for  temperature)  and  as  percentages  (for
precipitation)  from the base period values.  The outputs of HadCM3 coupled atmosphere-ocean
GCM  model  for  the  A2  and  B2  SRES  emission  scenarios  were  used  to  produce  the  future
scenarios.  The  study  found  that  there  is  an  overall  increasing  trend  in  annual  temperature  and
significant  variation  of  monthly  and  seasonal  precipitation  from  the  base  period  level.  These
changes of the climate variables were applied to SWAT hydrological model to simulate future
water  availability.  SWAT  was  calibrated  with  fifteen  years  of  data  (1985-1999)  to  assess  the
possible  impact  of  climate  change  in  the  Basin.  Stream  flow  model  efficiency  by  regression
coefficient  and  Nash-Sutcliffe  was  0.713  and  0.664  for  calibration  and  0.83  and  0.62  in
validation  respectively.  The  future  climate  variables  as  an  output  from  the  GCM  model  and
downscaled by the SDSM model and directly as an input to the SWAT model.  As a result of the
average total annual flow at the outlet of the study area might decrease up 11.13% and 10.24%
for both A2a and B2a scenario respectively at 2013-2040 period, 14.43% and 23.46% for both
A2a and B2a scenario respectively at 2041-2070 and 27.15% and 22.11% for both A2a and B2a
scenario respectively at 2071-2099.The decrease in the future flow of 2013-2040 periods might
be  unsatisfactory  in  some  months  to  meet  future  demands  for  the  water  of  the  ever  growing
population within and around the basin. The future possible volume of deficiency or hydrological
drought  appears  below  the  Q70
line,  it  indicates  the  hydrological  drought.  The  study  area  of
drought was observed 313 months of 1044 for both scenarios.

description: The Caldeira-Leggett Hamiltonian (Eq. (1) below) describes the interaction of a discrete harmonic oscillator with a continuous bath of harmonic oscillators. This system is a standard model of dissipation in macroscopic low temperature physics, and has applications to superconductors, quantum computing, and macroscopic quantum tunneling. The similarities between the Caldeira-Leggett model and the linearized Vlasov-Poisson equation are analyzed, and it is shown that the damping in the Caldeira-Leggett model is analogous to that of Landau damping in plasmas [1]. An invertible linear transformation [2, 3] is presented that converts solutions of the Caldeira-Leggett model into solutions of the linearized Vlasov-Poisson system.

EVALUATION OF CLIMATE VARIABILITY AND CHANGE ON  WATER RESOURCES AVAILABILITY FOR MAJOR WATER  RESOURCES DEVELOPMENT PROJECTS IN THE TANA BELES SUB-BASIN
Creators: name: ZELEKE BELAY ADMASU
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: To optimize benefits of the ongoing and planned water resources developments for sustainable socio
economic  development  in  Tana  and  Beles  sub-basin,  Ethiopia,  an  integrated  adaptive  water
resources management system is crucial. The objective of this study is to provide inputs to adaptive
water management by evaluating the impact of ongoing and planned water resources developments
with and without climate change on performance of Beles hydropower and main irrigation projects in
Tana-Beles  sub-basins.  This  study  is  different  from  previous  studies  for  the  study  area  since  high
resolution  climate  data  and  new  climate  scenario  are  used.  Two  independent  water  resources
scenarios were evaluated.  Scenario I refers to implementation of the water resources development
projects  without  climate  change,  i.e.  using  historical  climate  data. Scenario  II  refers  to
implementation of the water resources development projects under climate change for three future
periods:  near  term  (2011-2040),  medium  term  (2041-2070)  and  long-term  (2071-2095)  with  a
baseline scenario (1971-2000). Dynamically downscaled climate model outputs were obtained from
CORDEX-Africa program for the Representative Concentration Pathway of RCP4.5.The climate data
was bias corrected before serving as input to the impact models. The HBV-96 rainfall-runoff model
was used to simulate inflow of Lake Tana while WEAP21 was applied to assess the performance of
the  water  resources  projects.  Under  Scenario-I  (without  climate  change),   the  reliability  of
hydropower production reaches 83% with 100% demand coverage while there is considerable unmet
irrigation  water  demand.  Under  Scenario-II  (with  climate  change),  water  resources  availability
(inflow  to  Lake  Tana,  net  basin  supply  and  lake  storage  level)  of  all  future  scenarios  will  likely
increased unlike medium term scenario inhabited with insignificant change. Medium-term scenario
will face a considerable unmet demand of Tana sub-basin irrigation projects and Beles hydropower
reliability of 76%. This will be promoted in the near and long-term scenario with reliability of Beles
hydropower  by  90%  and  91.7%  respectively.  The  most  likely  affected  major  irrigation  projects  by
climate change are Jema and Megech followed by Ribb, Gumara, Koga and Tana pump irrigation
sites. The two independent scenarios were evaluated without affecting standard minimum operation
of the lake safe for navigation and downstream environmental flow requirement. For both scenarios
(with and without climate change) the maximum unmet demand for Beles hydropower will be 4.5%
and  13%  respectively  showing  that  impact  of  water  resources  development  on  Hydropower  is
insignificant.

description: The  main  aim  of  this  study  was  to  understand  the  groundwater  potential  of  Borkena  river
catchment for domestic  and  agricultural  uses.  Water qualitative  analysis  and recharge  estimation
of  groundwater resource  for sustainable  use and groundwater flow modeling were conducted in
the catchment.  The fast population growth,  uncontrolled urbanization and industrialization, poor
sanitary situation, uncontrolled solid  and  liquid waste disposal,  oil fuel etc. caused series quality
degradation of the river  and  borehole waters in the  catchment. Therefore,  evaluation  of physico
chemical  parameters  of  the  river  water  and  boreholes  in  the  catchment  of  Borkena  was

8.4 mg/l, 7.93 mg/l respectively.
The amount of natural groundwater recharge is a pre-requisite for efficient groundwater resource
evaluation and water balance approaches were used to  estimate  the annual  groundwater recharge
of  the  area.  It  was  found  to  be  133mm/year  which  is  11.5%  of  the  total  precipitation  of  the
catchment.
Processing  MODFLOW  Pro  is  useful in  confirming  the  distribution  of recharge  when  used  in
combination  with  a  water  balance  model  but  relies  on  the  correct  assumptions  on  the
hydrogeological model.  PMWIN Pro proved to be a very useful tool for the analysis of the water
budget  of  the  catchment.  The  model  was  calibrated  for  steady  state  condition  by  matching
simulated and observed hydraulic head data  for different periods. Model calibration was carried
out  by  trial  and  error  calibration  method  using  groundwater  contours  constructed  from  heads
collected for 11 wells. The calibration showed small error of simulated heads and the overall root
mean square errors for simulated hydraulic heads was found to be 3.96m.

However, the origin of this effect is not well known to date, and quantitative studies are rare. Here, we present the first statistical investigation of a sample of 76 HI discs using the WHISP survey. We perform a Fourier analysis to study the morphological lopsidedness. This allows to trace the degree of asymmetry with radius. We further investigate the dependence on, e.g., the morphological type and the environment.

description: The Nyabugogo River, located in the Nyabugogo watershed in central area of Rwanda, is
an important water resource for people living in this area. Agriculture dominates land use
in the basin, while the river receives waste water effluent from the town of Kigali capital
city.
The  purpose  of  this  study  was  threefold.  First,  to  evaluate  the  water  quality  of  the
Nyabugogo River and compare water quality parameters at different sites. Then, to study
selected parameters by using water quality index (WQI) and evaluate its suitability for
livestock and drinking use. Lastly to discuss the statistical results based on WHO surface
water quality Standards for dinking purpose. WQI was calculated on the basis of Weighted
Arithmetic Index by analyzing 12 physico-chemical parameters at Rwesero, Rusine, and
Giticyinyoni sites. The overall WQI results showed high pollution values at two sites for
rainy and dry season, except at Rwesero. On other side, the water quality parameters that
were  examined  statistically  include  physical,  chemical,  and  microbiological  parameters
where thirteen sampling sites were chosen along the Nyabugogo River. Turbidity and Lead
levels were high in all sites monitored, the highest average concentration of turbidity was
(3675.3NTU) at Rusine while Lead was (0.08g/L) at Nyacyonga site. These concentrations
exceeded  water  quality  guidelines.  The  average  concentration  of  DO  was  highest
(7.0mg/L) at Mwange. The conductivity was above the WHO limit at Rwesero, bridge1
and wetland sites, with the highest average concentration (408.3 s/cm) at wetland site. It
was found that the concentrations of faecal coliform and E.coli were higher to the WHO
limit especially downstream of the city indicates the untreated wastewater disposal from
the Kigali city. Moreover, nitrate showed a higher pollution with a highest average value
of (37.1 mg/L).
This thesis revealed that both urbanized and rural area have serious but different types of
pollution.  Based  on  the  parameters  concentrations  and  the  land  uses  impacts,  it  was
concluded that domestic and agricultural waste strongly influenced the variation and the
quality of the Nyabugogo River.
