Powered wheelchair skills training for older adults with cognitive impairment : using shared control to facilitate independence
Creators: name: Smith, Emma Maria
Publisher: name: University of British Columbia
Year: 2019

description: Powered wheelchairs (PWCs) promote participation and well-being for individuals with limited mobility. However, many individuals who would benefit from a PWC do not have access to one. This is particularly true for older adults with cognitive limitations who are perceived as being unable to learn or require additional training to become safe and effective drivers. Novel training approaches which address the needs of this population, while maintaining safety in the training environment, are necessary. Purpose: To generate knowledge through end-user input to develop a wheelchair skills training program for older adults with cognitive impairment, using an errorless learning approach, and evaluate the feasibility of implementing this program in a randomized controlled trial for individuals living in residential care. Methods: To address the purpose, we conducted three studies: A North American survey of PWC skills training providers; qualitative interviews; a think-aloud task analysis; and a mixed-methods feasibility 2x2 factorial randomized controlled trial. Results: Evidence-based PWC skills training programs are rarely used in current practice. The most commonly used training techniques are trial-and-error methods using verbal and visual cues, with safety maintained through proximity to the wheelchair. Clinicians experience tensions in providing client-centred practice in resource limited environments and maintaining safety during training while meeting the learner’s needs. There is a perception shared control technology may enable safe training opportunities and reduce training related anxiety and stress, however, clinicians require training and practice with new technologies to ensure competence. The majority of the skills and abilities used when driving a PWC are mental functions, while knowledge of the self, environment, wheelchair, and activity or task are used during driving. An errorless intervention for PWC skills training, facilitated by shared control, is safe and effective for training new wheelchair users with cognitive impairment. Participants felt safe and benefitted from the use of shared control. Conclusion: Although many clinicians are hesitant to train individuals with cognitive impairments, learning is possible within this population. Shared control can facilitate errorless training strategies. Future research should incorporate alternative trial designs, integration into clinical practice, and wheelchair-related outcome measures validated for use with older adults with cognitive impairment.

Year: 2015

description: The  main  aim  of  this  thesis  is  to  study  the  current  and  future  water  availability  and
allocation under changing climate condition in Lower Nyabarongo river catchment in the
developing country, where demands are growing and the supply seems to be constant.
Assessment of impact of climate change on water resources in river catchment requires a
proper estimation of availability of water and that can only be achieved by hydrologica
modeling of the catchment.  In this study a catchment simulation model (HEC-HMS) has
been  calibrated  and  validated  for  Lower  Nyabarongo  catchment  for  forecast  of  its
hydrologic response. The future stream flow forecasted in the  catchment  were simulated
by  the  dynamically  downscaled  RCP  4.5  (Representative  Concentration  Pathways
scenarios  has  been  adopted  from  CORDEX  archive  and  bias  correction  were  done  by
using  power  transformation  equation  before  using  in  Hydrologic  Engineering  Cente
Hydrologic  Modeling  system  (HEC-HMS  model).  The  annually  result  of  current  and
future water availability from 1983-2010 and 2011 to 2040 in the catchment was found to
be  7482.14Million  Cubic  Meter  (MCM)  and  5951.67Million  Cubic  Meter  (MCM
respectively.
Water  Evaluation  and  Planning  System  (WEAP)  model  is  used  for  the  study  for  wate
allocation  of  the  river  water  based  on  the  existing  water  requirement  and  user  priority
setting  situation.  The  water  resources  availability  assessment  and  the  allocations  are
performed  for  two  scenarios;  Scenario  I:  The  current  (1983-2010)  water  use  rate.  This
scenario  holds  the  overall  existing  water  supply  in  Kigali,  Muhanga,  Gicumbi  and
Rwamagana  city.  Also  two  irrigation  scheme  and  industry  demand  takes  into  account
The  overall  irrigable  area  in  this  scenario  is  around  864.93ha.  Scenario  II:  The  presen
water use rate plus various schemes under Planed. In this scenario the total irrigable area
under  this  scenario  is  5,000  ha.  According  to  future  scenario  period  the  Kajevuba  and
Kanyenyomba  irrigation  projects  shows  increasing  monthly  water  demand  from  3.83
Million  Cubic  Meter  to  64.57  Million  Cubic  Meter  due  to  extension  of  the  irrigation
scheme.  The  Annually  water  demand  and  supplied  for  the  current  period  found  to  be
78.49MCM while the demand rises to 244.10 MCM for the future scenario with unme
demand of 165.61 Million Cubic Meter (67.87%)

Creators: name: TESFA YIMER
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Hydrological  models are  influential    tools for simulating the effect of watershed processes
and  management  on  soil  and  water  resources.  The  main  objective  of  this  study  was
comparative hydrological modeling of Maybar watershed using SWAT-WB and SAWT-CN
in  order  to  understand  hydrological  components  of  Watershed  and  to  evaluate  the
performance  of  the  models  for  simulating  stream  flow.  The  Arc  SWAT  interface
implemented in the ArcGIS software was used to delineate the sub-basin, combine the data
layers and edit the model database.  The effective depth of the soil profile values for seven
soil  types  was  assigned  based  on  the  topographic  index  of  the  watershed.  The  hydro
meteorological  data  collected  from  nearby  stations  and  the  missed  data  were  filed  by
arithmetic  mean  and  simple  interpolations.    Sensitivity  analysis  was  conducted  for  both
SWAT-WB & SWAT-CN. The sensitivity result showed base flow alpha factor & maximum
canopy storage are the most sensitive parameters for SWAT-WB &SWAT-CN respectively.
The models were calibrated and validated on Maybar watershed using Sequential Uncertainty
Fitting  and  Generalized  Likely-hood  Uncertainty  estimation  for  SWAT-WB  &SWAT-CN.
Sequential  Uncertainty  Fitting  gives  good  result  compared  to  Generalized  Likely-hood
Uncertainty  estimation.  SWAT-WB  was  performed  slightly  better  during  calibration  than
SWAT-CN with the value of Sequential Uncertainty Fitting of (0.91 &0.87) for SWAT-WB
& SWAT-CN respectively.  In the validation period SWAT-WB was also performed better
than SWAT-CN with the value of Sequential Uncertainty Fitting of (0.85&0.78) for SWAT
WB  and  SWAT-CN  respectively.  All  sources  of  uncertainty  captured  by  bracketing  more
than  33%  for  SWAT-WB  &  51%  of  SWAT-CN.  Base-  flow  (64.2%  -  71.46%)  is  an
important  component  of  the  total  discharge  compared  to  surface  runoff  in  the  study  area.
Based on the statistical indicators, the evaluation indicates that SWAT-WB &SWAT-CN had
very good performance for both month calibration and validation period. The statistical result
revealed that if properly calibrated SWAT-WB can be used more effectively than SWAT-CN
in Monsoonal climate like Ethiopia.

description: For the phenomenological description of magnetohydrodynamic turbulence competing models exist, e.g. Boldyrev [Phys.Rev.Lett. \textbf{96}, 115002, 2006] and Gogoberidze [Phys.Plas. \textbf{14}, 022304, 2007], which predict the same Eulerian inertial-range scaling of the turbulent energy spectrum although they employ fundamentally different basic interaction mechanisms. {A relation is found that links} the Lagrangian frequency spectrum {with} the autocorrelation timescale of the turbulent fluctuations, $τ_\mathrm{ac}$, and the associated cascade timescale, $τ_{\mathrm{cas}}$. Thus, the Lagrangian energy spectrum can serve to identify weak ($τ_\mathrm{ac}\llτ_{\mathrm{cas}}$) and strong ($τ_\mathrm{ac}\simτ_{\mathrm{cas}}$) interaction mechanisms providing insight into the turbulent energy cascade. The new approach is illustrated by results from direct numerical simulations of two- and three-dimensional incompressible MHD turbulence.

HYDROLOGICAL DROUGHT ANALYSIS UNDER CLIMATE CHANGE  SCENARIO FOR UPPER BLUE NILE BASIN, ETHIOPIA (A CASE STUDY OF KESSIE SUB-BASIN)
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 Kessie sub-basin is exposed 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  sub
basin  based  on  daily  data  from  1983-2012,  in  11  stations  over  the  study  area  were  obtainable
using SWAT model. These changes of the climate variables were applied to SWAT hydrological
model  to  simulate  future  water  availability.  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.  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  Q
70
line,  it  indicates  the  hydrological  drought.  According  to  the
output, in this study area the hydrological drought was observed 313 months within 1044 months
for both A2a and B2a scenarios.

Year: 2010

description: The paper presents three self-stabilizing protocols for basic fair and reliable link communication primitives. We assume a link-register communication model under read/write atomicity, where every process can read from but cannot write into its neighbours' registers. The first primitive guarantees that any process writes a new value in its register(s) only after all its neighbours have read the previous value, whatever the initial scheduling of processes' actions. The second primitive implements a "weak rendezvous" communication mechanism by using an alternating bit protocol: whenever a process consecutively writes n values (possibly the same ones) in a register, each neighbour is guaranteed to read each value from the register at least once. On the basis of the previous protocol, the third primitive implements a "quasi rendezvous": in words, this primitive ensures furthermore that there exists exactly one reading between two writing operations All protocols are self-stabilizing and run in asynchronous arbitrary networks. The goal of the paper is in handling each primitive by a separate procedure, which can be used as a "black box" in more involved self-stabilizing protocols.

description: We present a first look at the local LIRG, IRAS04296+2923. This barred spiral, overlooked because of its location in the Galactic plane, is among the half dozen closest LIRGs. More IR-luminous than either M82 or the Antennae, it may be the best local example of a nuclear starburst caused by bar-mediated secular evolution. We present Palomar J and Pa beta images, VLA maps from 20-1.3cm, a Keck LWS image at 11.7mic and OVRO CO(1-0) and ^13CO(1-0), and 2.7 mm continuum images. The J-band image shows a symmetric barred spiral. Two bright, compact mid-IR/radio sources in the nucleus comprise a starburst that is equivalent to 10^5 O7 stars, probably a pair of young super star clusters separated by 30pc. The nuclear starburst is forming stars at the rate of ~12Msun/yr, half of the total star formation rate for the galaxy of ~25Msun/yr. IRAS04296 is bright in CO, and among the most gas-rich galaxies in the local universe. The CO luminosity of the inner half kpc is equivalent to that of the entire Milky Way. While the most intense CO emission extends over a 15"(2 kpc) region, the nuclear starburst is confined to ~1-2"(150-250 pc) of the dynamical center. From ^13CO, we find that the CO conversion factor in the nucleus is higher than the Galactic value by a factor 3-4, typical of gas-rich spiral nuclei. The nuclear star formation efficiency is M_gas/SFR^nuc = 2.7x10^-8 yr^-1, corresponding to gas consumption timescale, tau_SF^nuc~4x10^7 yrs. The star formation efficiency is ten times lower in the disk, tau_SF^disk~3.3x10^8 yrs. The low absolute star formation efficiency in the disk implies that the molecular gas is not completely consumed before it drifts into the nucleus, and is capable of fueling a sustained nuclear starburst. IRAS04296 is beginning a 100Myr period as a LIRG, during which it will turn much of its 6x10^9Msun of molecular gas into a nuclear cluster of stars. (abridged)

Resistive transition in disordered superconductors with varying intergrain coupling

description: The effect of disorder is investigated in granular superconductive materials with strong and weak links. The transition is controlled by the interplay of the \emph{tunneling} $g$ and \emph{intragrain} $g_{intr}$ conductances, which depend on the strength of the intergrain coupling. For $g \ll g_{intr}$, the transition involves first the grain boundary, while for $g \sim g_{intr}$ the transition occurs into the whole grain. The different intergrain coupling is considered by modelling the superconducting material as a disordered network of Josephson junctions. Numerical simulations show that on increasing the disorder, the resistive transition occurs for lower temperatures and the curve broadens. These features are enhanced in disordered superconductors with strong links. The different behaviour is further checked by estimating the average network resistance for weak and strong links in the framework of the effective medium approximation theory. These results may be relevant to shed light on long standing puzzles as: (i) enhancement of the superconducting transition temperature of many metals in the granular states; (ii) suppression of superconductivity in homogeneously disordered films compared to standard granular systems close to the metal-insulator transition; (iii) enhanced degradation of superconductivity by doping and impurities in strongly linked materials, such as magnesium diboride, compared to weakly-linked superconductors, such as cuprates.

description: Multidomain crowd counting aims to learn a general model for multiple diverse datasets. However, deep networks prefer modeling distributions of the dominant domains instead of all domains, which is known as domain bias. In this study, we propose a simple-yet-effective Modulating Domain-specific Knowledge Network (MDKNet) to handle the domain bias issue in multidomain crowd counting. MDKNet is achieved by employing the idea of `modulating', enabling deep network balancing and modeling different distributions of diverse datasets with little bias. Specifically, we propose an Instance-specific Batch Normalization (IsBN) module, which serves as a base modulator to refine the information flow to be adaptive to domain distributions. To precisely modulating the domain-specific information, the Domain-guided Virtual Classifier (DVC) is then introduced to learn a domain-separable latent space. This space is employed as an input guidance for the IsBN modulator, such that the mixture distributions of multiple datasets can be well treated. Extensive experiments performed on popular benchmarks, including Shanghai-tech A/B, QNRF and NWPU, validate the superiority of MDKNet in tackling multidomain crowd counting and the effectiveness for multidomain learning. Code is available at \url{https://github.com/csguomy/MDKNet}.

description: We investigate the possibility of detecting dark matter at TeV scale linear colliders in the scenario where the dark matter is a massive particle weakly interacting only with the Higgs boson $h$ in the low energy effective theory (the Higgs portal dark matter scenario). The dark matter in this scenario would be difficult to be tested at the CERN Large Hadron Collider when the decay of the Higgs boson into a dark matter pair is not kinematically allowed. We study whether even in such a case the dark matter $D$ can be explored or not via the $Z$ boson fusion process at the International Linear Collider and also at a multi TeV lepton collider. It is found that for the collision energy $\sqrt{S}>1$ TeV with the integrated luminosity 1 ab$^{-1}$, the signal ($e^{\pm}e^-\to e^{\pm}e^-h^\ast \to e^{\pm}e^-DD$) can be seen after appropriate kinematic cuts. In particular, when the dark matter is a fermion or a vector, which is supposed to be singlet under the standard gauge symmetry, the signal with the mass up to 100 GeV can be tested for the Higgs boson mass to be 120 GeV.

description: Crop  water  estimation  is  relevant  to  address  issues  such  as  proper  utilization  of  water,
prediction  of  crop  productivity  to  design  irrigation  systems,  resources,  farm  irrigation
scheduling and environmental assessment. An experiment was conducted during April to July
in 2015 at Jawe and Kerekicho  Kebeles in  SNNP. The aim was  to measure ETc,  Kc  of Desho
grass, oats and vetch fodder crops; with objective of evaluating the WFD (scheduling tool) in
terms  of  biomass  yield  and  water  productivity.  The  study  was  among  two  treatments  with
three replicated plots  at  each  of the  study  areas  and each plot size prepared was 10 m X 10
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.
"Playing with monopoly money" : a participatory exploration of the space-time aspects of homeless social capital
Creators: name: Cook, Shelley B.
Publisher: name: University of British Columbia

description: Social capital is generally understood as the benefits received through people’s relationship with others. Although social capital is recognized as a fundamental ingredient in the psychological and material wellbeing of all people, little is known about how it functions for the homeless. Even less is known about context-sensitive accounts that consider the relevance of space and time in the production of social capital, the connection to the construction of homeless identity, and how social capital experiences of homeless people vary based on different factors, including gender. My doctoral research is an exploratory, participatory investigation of the space-time aspects of homeless social capital and the relationship to the trajectory of homelessness. It furthers theoretical and practical knowledge of homelessness, social capital, and the influence of gender through the use of Bourdieusian social capital theory and multiple methods and data sources. My research was conducted in Kelowna, BC, a mid-sized Canadian city, and involved one-year of fieldwork with time spent on city streets in locations known to be pivotal hubs of homeless activity. I conducted participatory mapping on an individual-basis with 29 street homeless adults, and on a group-basis with participants separated through a female/male binary. I used an advisory committee composed of formerly homeless people to guide research and interviews with key stakeholders with knowledge of street homelessness locally to inform my research approach. As a way to enhance policy and service recommendations, focus groups with key stakeholders and the advisory committee for the project were used to leverage research findings. Three key areas of findings were identified: 1) six distinct categories of homeless social capital with defined geographies, temporal aspects, and gender profiles; 2) three categories of fixed or variable factors with gender being the most important in shaping the space-time aspects of homeless social capital; and, 3) key themes from the thematic analysis of qualitative data, including the prevalence of negative social capital, the conscious performance of representations of homeless identity, and pronounced gender differences in the space-time aspects of social capital, including gendered survival and resistance strategies. The many theoretical, methodological, and practical implications are discussed.

hydrologists.  This  long-standing  issue  has  received  increased  attention  recently  due  to  the
prediction in ungauged basin initiative by the International Associations of Hydrological Science.
In  developing  countries  like  Ethiopia  most  of  the  Rivers  are  ungauged.  Therefore,  applying
regionalization techniques for ungauged or poorly gauged river basin is crucial.  This paper deals
with predicting discharge at ungauged catchments using conceptual lumped rainfall-runoff model
HBV-96 in Didessa sub-basin.  Four regionalization methods (multiple linear regression, spatial
proximity, area ratio and sub-basin mean) were applied to transfer model parameter values from
the gauged to the ungauged catchments. In regional model, gauged catchments model parameters
and physical  catchment characteristics  of ungauged catchments were used to develop the  equations
in order to  predict discharge from  ungauged catchments.  To have better understanding of model
parameter  performance,  the  sensitivity  analysis  of  eight  model  parameters  were  performed
manually  by  trial  and  error.  The  evaluation  shows  that  runoff  coefficient  (Beta),  recession
coefficient  of upper reservoir zone (Khq),  limit for evapotranspiration (LP), field capacity (Fc),
percolation (Perc) and capillary rise coefficient (Cflux) are more sensitive than others. The model
performance was evaluated using Nash Sutcliff efficiency and relative  volume error. The  result
shows  that  from seven gauging river four of them have good  agreement and distribution  since  Nash
Sutcliff efficiency  greater than 0.60 and  relative volume error  lies between +10%  and  -10%.  In
predicting model parameters from ungauged catchments in regional model method p-value ≤ 0.1
and  determination  coefficient  (R
2
)  ≥  0.94  were  obtained.  The  model  parameters  in  ungauged
catchments  were  determined  by  using  regional  model,  sub-basin  mean,  area  ratio  and  spatial
proximity  methods  and  simulated  the  discharge  by  using  HBV-96  model.  River  flow  from
ungauged catchments simulated  by regional model  method  was the best.  Therefore, regional model
method is recommended in predicting discharge for ungauged catchments.

description: This  study  intended  to  introduce  the  concept  of  comparative  performance  indicators  with
some  irrigation  efficiencies  indicators  such  as  water  application  efficiency  and  distribution
uniformity  as tool to evaluate the performance of two small scale irrigation projects namely
Ntende and Rwagitima located in Ntende Rwagitima marshland in Rwanda.
In order to evaluate the irrigation water use efficiency of farmers at field level three farmers
were selected from each irrigation projects in relation to their location (from the head, middle
and  tail  end)  for  required  primary  data  collection  while  the  comparative  performance
indicators  relied  on  the  availability  of  secondary  data  required  to  calculate  th e  all  nine
external  indicator  as  developed  by  International  Water  Management  Institute‟s.  To  analyze
the collected data different appropriate  formulas,  International  Water Management Institute‟s
Comparative  performance  indicators  calculation  and  Models  like  CROPWAT  for  seasonal
crop  water  requirement  and  irrigation  requirement  and  AQUACROP  for  assessing  the
potential land productivity in order to find out the performance gap  were used.
From  the  data  analysis,  the  resultants  of  water  irrig ation  efficiencies  showed  that  the
application efficiencies  of  Kiliba  are  64.77%, 60.62 and 60.59 respectively for field 1,  field 2
and  field  3  while  the  application  efficiencies  of  Ntende  are  62.47%,  60.16%  and  60.39  %
respectively  for  field  1,  field  2  and  field  3.  The  values  of  distribution  efficiency  all  fields
were found to be close to 100% while those of efficiency of the canal system to convey water
showed  that  there  is  water  loss  over  a  given  travel  distance  because  of  earthen  canal.   For
comparative  performance  indicators,  the  resultants  showed  Ntende  irrigation  scheme
performs  better  in  terms  of  land  productivity  compared  to  Kiliba  while  the  latter  is  more
productive in terms of water  productivity. The  financial self-sufficiency of both schemes are
still  lower  (imbalance  between  incomes  &  expenditures)  and  both  schemes  are  poorly
performing compared to their potentials  land productivity..

EVALUATION OF IMPACT OF CLIMATE CHANGE ON WATER RESOURCE  AVAILABILITY OF ABAYA - CHAMO BASIN: (A CASE STUDY OF KULFO CATCHMENT),ETHIOPIA
Creators: name: TADELECH ALEM
Publisher: name: National Academic Digital Repository of Ethiopia
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. Accordingly, this impact is significant on the water
resource system. This study mainly deals with evaluation of the climate change impacts  on
the  Kulfo  catchment  which  is  found  in  Rift  valley.  Statistical  Down  Scaling  Method  was
applied in order to downscale the climate variables at catchment level. SDSM was also used
to  downscale  the  present  and  future  monthly  precipitation  and  temperature  from  the  UK
Hadley center (HadCM3). Two future emission scenarios, A2 and B2 were considered for the
three  different  periods  2030s  (2020-2049),  2060s  (2050-2079)  and  2090s  (2080-2099).
Downscaling was done to obtain finer resolution output from the GCM, so that it matches
with the Kulfo catchment scale. The downscaled  future climate showed that the mean daily
minimum and maximum  temperature  increase  may  up to 1.65/2.0 (2030s), 1.66/3.0 (2060s)
and  1.66/3.6 (2090s) and  an increase of rainfall with change of 2% (2030s) 6% (2060s) and
11% (2080-2099) for A2 scenario with respect to the baseline period and 1% (2030s), 4%
(2060s)  and  9  %(  2090s)  for  B2  scenario.  The  output  of  downscaled  data  provided  input
rainfall  and  temperature  data  for  the  HEC-HMS  model  to  estimate  flow.  A  hydrological
model,  HEC-HMS  was  utilized  to  simulate  the  flow.  The  performance  of  the  model  was
assessed  through  calibration  and  validation  process  and  resulted  R
2
=0.86  and  NSE=0.85
during calibration and R
2
=0.85, NSE =0.79  during validation.  The generated flow to Sikela
gauge shows an average annual increase by 24.9% in 2050s (2043-2052) and 26.3% in 2090s
(2090-2099) under A2  scenario. The B2 emission scenario projects that the average annual
flow  volume  will  increase  by  20.9%  in  2050s  (2043-2052)  and  26.11%  in  2090s  (2090-
2099).The  increasing  of  seasonal  mean  flow  in  Bega  (JFD)  has  its  own  contribution  for
occurrence  of  flooding  in  Kulfo  Catchment.  It  is  observed  that  there  may  be  a  net  annual
increase in mean annual flow volume in Kulfo River due to climate change.

description: Given a graph G with a distinguished vertex s, the critical group of (G,s) is the cokernel of their reduced Laplacian matrix L(G,s). In this article we generalize the concept of the critical group to the cokernel of any matrix with entries in a commutative ring with identity. In this article we find diagonal matrices that are equivalent to some matrices that generalize the reduced Laplacian matrix of the path, the cycle, and the complete graph over an arbitrary commutative ring with identity. We are mainly interested in those cases when the base ring is the ring of integers and some subrings of matrices. Using these equivalent diagonal matrices we calculate the critical group of the m-cones of the l-duplications of the path, the cycle, and the complete graph. Also, as byproduct, we calculate the critical group of another matrices, as the m-cones of the l-duplication of the bipartite complete graph with m vertices in each partition, the bipartite complete graph with 2m vertices minus a matching.

description: We examine many SO(10) models for their viability or otherwise in explaining all the fermion masses and mixing angles. This study is carried out for both supersymmetric and non-supersymmetric models and with minimal ($10+\bar{126}$) and non-minimal ($10+\bar{126}+120$) Higgs content. Extensive numerical fits to fermion masses and mixing are carried out in each case assuming dominance of type-II or type-I seesaw mechanism. Required scale of the B-L breaking is identified in each case. In supersymmetric case, several sets of data at the GUT scale with or without inclusion of finite supersymmetric corrections are used. All models studied provide quite good fits if the type-I seesaw mechanism dominates while many fail if the type-II seesaw dominates. This can be traced to the absence of the $b$-$τ$ unification at the GUT scale in these models. The minimal non-supersymmetric model with type-I seesaw dominance gives excellent fits. In the presence of a $45_H$ and an intermediate scale, the model can also account for the gauge coupling unification making it potentially interesting model for the complete unification. Structure of the Yukawa coupling matrices obtained numerically in this specific case is shown to follow from a very simple U(1) symmetry and a Froggatt-Nielsen singlet.

description: After the prediction that strong enough optical activity may result in negative refraction and negative reflection, more and more artificial chiral metamaterials were designed and fabricated at difference frequency ranges from microwaves to optical waves. Therefore, a simple and robust method to retrieve the effective constitutive parameters for chiral metamaterials is urgently needed. Here, we analyze the wave propagation in chiral metamaterials and follow the regular retrieval procedure for ordinary metamaterials and apply it in chiral metamaterial slabs. Then based on the transfer matrix technique, the parameter retrieval is extended to treat samples with not only the substrate but also the top layers. After the parameter retrieval procedure, we take two examples to check our method and study how the substrate influences on the thin chiral metamaterials slabs. We find that the substrate may cause the homogeneous slab to be inhomogeneous, i.e. the reflections in forward and backward directions are different. However, the chiral metamaterial where the resonance element is embedded far away from the substrate is insensitive to the substrate.
