Tau-congruent numbers and integers in number fields
Creators: name: Davis, Chad Tyler
Publisher: name: University of British Columbia
Year: 2019

description: A positive integer n is the area of a Heron triangle if and only if there exists a non-zero rational number tau such that the elliptic curve E^n_tau: Y² = X(X-n tau)(X+n tau-¹) has a rational point of order different than two. Such an integer n is called a tau-congruent number. In the first part of this thesis, we give two distribution theorems on tau-congruent numbers; in particular we show that given any fixed, non-zero rational tau, there exist infinitely many tau-congruent numbers in every residue class modulo any positive integer m, and we also prove a similar result for tau-congruent numbers whose corresponding elliptic curves have rank at least 2. In the second half of this thesis, we give some theorems on integers in certain algebraic number fields. First, we completely determine the index of a quartic field defined by a polynomial of the form X⁴ + aX + b. Second, we determine all possible normal integral bases in a certain cyclic quintic field. Finally, we give a family of cubic polynomials that define number fields that are both monogenic and have the same discriminant.

description: The  study  aims  at  evaluating  physical  suitability  (land  and  water resource)  for
surfaceirrigation  development  using  GIS  techniques.  The Segen sub-basin  was  selected  as
acase study for this thesis work which is located at the Southern part ofthe Rift Valley River
Basin covering an area of about 20,517 km
2
.
The evaluation of land in terms of the suitability classes for surface irrigation was basedon
the method as described in FAO guideline for land evaluation. The essence of landevaluation
for  irrigation is  to  compare  or  match  the physical  resource  of  soil,  water,  topography  and
others with the irrigation requirement. A land unit is obtained by the overlaying of selected
theme layers, which has uniqueinformation of land qualities for which the suitability is based
on.  The  selected  themelayers  for  this  study  include  soil  types,  with  their  corresponding
physical and chemicalcharacteristics that affect irrigation agriculture, land cover, and slope
layer, which isderived from the Digital Elevation Model of the study area. As its being the
mostlimiting  factor  for  the  realization  of,  especially  for  surface  irrigation  method,  the
slopelayer was used as the base map for the overlaying analysis.
The  suitable  land  identified  categorized  according  to  the  different  climatic  zones  alongthe
Weito and Segen River in the sub-basin. They are mostly concentrated in the South central
and North Eastern part of the sub-basin.The 95, 90, 85, and 80 percentage time exceedance
flow of the available surface waterin the respective climatic zones was estimated and the area
that can be irrigated withthis flow was computed using the selected climatic station data and
estimated ETo.Surface irrigation land suitability analysis indicate that 70.9 % of soil and 52.5
% slope in thestudy area are in the range of highly suitable to marginal suitable for surface
irrigation systemwhereas the remaining 29.1%  (soil) and 47.5% (slope) in the area  are not
suitable. In terms ofland cover/use, land covered by settlement, degraded shrub land, forest,
wetland, water bodyand grazing land covering 17.2% of the study area were restricted from
irrigationdevelopment.  When  these  factors  were  weighted  using  weighted  overlay  in  Arc
GIS, thepotential irrigable land for surface irrigation was reduced to 2.12%.
Assessment of Groundwater Potential Zones in Baro  Basin using GIS and Remote sensing

description: Baro  river  basin  located  in  southwest  of  Ethiopia  is  a  largest  sub  basin  of  Baro-Acoobo
basin.  For the proper utilization and management of groundwater resource  in the basin,  it
required to know its spatial distribution.  Hence, geographic information system and remote
sensing  techniques were  used  to analyze the groundwater system based on  seven  selected
groundwater  influence  factors  thematic  maps.  The  thematic  maps  we  used  were  geology,
soil,  lineament  density,  drainage  density,  rainfall  distribution,  slope  and  land  use  maps.
Lineament  and  land  use  maps  were  prepared  through  the  process  of  remote  sensing
techniques from Landsat 4-5 imagery using ERDAS imagine and PCI Geomatica softwares.
Other thematic maps  were  prepared using Arc GIS 9.3 from DEM and  previous prepared
soil and geology maps .for each maps weight value was estimated by using PriEst software
after  assigning  weight  value  of  domain  effect  by  using  pairwise  comparison  based  on
Saaty’s analytical hierarchy process. Finally thematic layers  were  integrated  in  Arc GIS  9.3
based  on  estimated  weight  values.  In  the  basin,  four  groundwater  potential  zones  were
identified;  namely:  excellent,  good,  moderate  and  poor.  Excellent  groundwater  potential
zones  are  associated with areas of alluvial deposition, flat and sand dominant  soil group of
western  part  of  the  basin;  north  and  eastern  portion  of  basin  have  good  and  moderate
potential zone. Poor potential zone are in areas of mountain  areas  which have  steep slope
and high drainage density in center of the basin.
Groundwater  recharge  of  the  basin  was  also  estimated  using  wetspass  model.  The  model
performs  recharge  estimation  by  using  water  balance  method  in  single  raster  cell  level.
Wetspass  model  inputs  are  grid  maps  of  elevation,  slope,  depth  to  water  table  or
groundwater,  land  use,  soil  and  seasonal  meteorological  grid  maps  such  as  temperature,
rainfall,  potential  evapotranspiration  and  wind  speed.  Wetspass  model  outputs  include
annual  recharge,  actual  evapotranspiration,  surface  runoff  and  others.  Estimated  annual
groundwater recharge reaches the highest  amount of 465 mm/ year in center of basin and
decreases to other areas of the basin.

description: In this paper we calculate the vacuum expectation values of the stress-energy bitensor of a massive quantum scalar field with general coupling to N-dimensional Euclidean spaces and hyperbolic spaces which are Euclidean sections of the anti-de Sitter (AdS) spaces. These correlators, also known as the noise kernel, act as sources in the Einstein-Langevin equations of stochastic gravity [1,2] which govern the induced metric fluctuations beyond the mean-field dynamics described by the semiclassical Einstein equations of semiclassical gravity. Because these spaces are maximally symmetric the eigenmodes have analytic expressions which facilitate the computation of the zeta-function [3,4]. Upon taking the second functional variation of the generalized zeta function introduced in [5] we obtain the correlators of the stress tensor for these two classes of spacetimes. Both the short and the large geodesic distance limits of the correlators are presented for dimensions up to 11. We mention current research problems in early universe cosmology, black hole physics and gravity-fluid duality where these results can be usefully applied to.

Numerical simulations of spicule formation in the solar atmosphere

Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We study the upward propagation of a localized velocity pulse that is initially launched below the transition region within the solar atmosphere. The pulse quickly steepens into a shock, which may lead to the formation of spicules. We solve two-dimensional time-dependent magnetohydrodynamic equations numerically to find spatial and temporal dynamics of spicules. The numerical simulations show that the strong initial pulse may lead to the quasi periodic rising of chromospheric material into the lower corona in the form of spicules. The periodicity results from the nonlinear wake that is formed behind the pulse in the stratified atmosphere. The superposition of raising and falling off plasma portions resembles the time sequence of single and double (sometimes even triple) spicules, which is consistent with observational findings. The two-dimensional rebound shock model may explain the observed speed, width, and heights of type I spicules, as well as observed multi-structural and bi-directional flows. The model also predicts the appearance of spicules with 3-5 min period due to the consecutive shocks.

description: In comparison to other countries belonging to the Communist Bloc in Central Eastern Europe all the activities created by the communist ideology were gradually aiming to completely eliminate the nuns' lifestyle in Poland. In the battle with the Catholic Church in People's Republic of Poland (PRL) the first goal was to eliminate religious orders. During the national sent of the Ministry of Public Security officers col. Julia Brystygierowa, the director of the Ministry of Public Security who specialized in the persecution of religion, delivered the speech "Clergies' offensive and our duties". She repeated many times that the elimination of the church
 and religion in Poland would have to be postponed. She considered the elimination of the religious orders as the most important as there were international and Polish samples - suppressions of the orders - that could be used. She presented the religious orders as "the most important link for the foreign intelligence service"

description: Thisstudy  First,  identify   potential irrigable land and characterize its nature of utility for surface
irrigation.  In  the  second  stage  estimate  potential  surface  water  resource  for  irrigation  and
determine crop water requirement for very common crops of the study area. Finally,  recommend
the storage volume demands  unless the available water resource would meet the demand of  the
potential area and crops.
The hydrological, meteorological, digital elevation model, soil, Land use, land cover map and etc
data were gathered from different organization of government  and otherconcerned sectors.Once
elevation data of the study area were delineated as 90m  by 90m  resolution, then, characteristics
of  flow  direction,  contours  and  radius  of  elevation  identified.  The  potential  irrigable  land  was
analyzed  by  using  slope,  land  use/cover  and  soil  in  arcGIS,  spatial  analysis  tool  to  test  their
suitability individually.
The  application  of   the  weighted  overlay  tool  was  provided  to  condense  overall  suitability
factors as specific outcome, and suitability was conducted implementing FAO criteria for surface
irrigation.  Analysis  of  the  water  resource  potential  of  the  study  area  was  carried  out  by  using
hydrological  data  after  filling  different  gaps  observed  using  techniques  like  the  average  mean
method and distance power method to screen them for further application. Here, there was, flow
duration  curve  developed,  flood  frequency  tested,  low  flow  analyzed  to  differentiate  between
variability  existed  between  time  series  of  the  records.  The  reservoir  requirements  of  the
catchment  were  dealt  with  dependable  flow  by  mass  curve  technique.  Also  crop  water
requirement  of  most  widely  growing  crops  of  the  study  area  viz.  Potato  and  Maize  were
computed from climatic data as an input depending on the preference of agro climatic condition
of the study area using CROPWAT model, version 8.
Potential  irrigable  land  was  identified  out  of  the  total  catchment  area  considering  suitability
outcomes for river catchments and selected crops  agro ecology.  The  Gross irrigation demand of
selected  crops for each month is computed for  low flow analysis of 80%, 85%, 90%, 95%, and a
100%  time  exceedence.  The area  that can be irrigated  considering  low flows  is 8627.8ha.  The
storage requirements  are  700,  105, 35 and 55,55Mm

description: The connection between QCD, a nonlocal Nambu--Jona-Lasinio type model and the Landau gauge gluon propagator is explored. This two point function is parameterized by a functional form which is compatible with Dyson-Schwinger and lattice QCD results. Demanding the nonlocal model to reproduce the experimental values for the pion mass, the pion decay constant, $Γ_{π\rightarrow γγ}$ and the light quark condensate we conclude that low energy physics does not distinguish between the so-called decoupling and scaling solutions of the Dyson-Schwinger equations. This result means that, provided that the model parameters are chosen appropriately, one is free to chose any of the above scenarios. Furthermore, the nonlocal Nambu--Jona-Lasinio quark model considered here is chiral invariant and satisfies the GMOR relation at the 1% level of precision.

description: We investigate the meaning of the entropy carried away by Hawking radiations from a black hole. We propose that the entropy for a black hole measures the uncertainty of the information about the black hole forming matter's precollapsed configurations, self-collapsed configurations, and inter-collapsed configurations. We find that gravitational wave or gravitational radiation alone cannot carry all information about the processes of black hole coalescence and collapse, while the total information locked in the hole could be carried away completely by Hawking radiation as tunneling.

description: Managing and archiving research data in a well-organized framework is an essential task in every interdisciplinary long-term research project. Within the framework of the Collaborative Research Centre TRR 228 “Future Rural Africa: Future-making and social-ecological transformation” (CRC/TRR228), a web-based research data management system, a so-called project database, was implemented by INF-project Z02 to handle all relevant research data of the project. This database should fulfill the obligations of the ‘Good Scientific Practice’ guidelines of the DFG to archive the data for at least ten years and also support synergies and communication between the researchers. Due to the interdisciplinary background of the project, the CRC/TRR228-Database (TRR228DB, www.trr228db.uni-koeln.de) has to store a large number of heterogeneous data, as for example collected research data, purchased geodata, reports, presentations, publications and pictures that were provided by the CRC/TRR228 participants. A central element of the database system is the developed metadata management system. It was designed, realized, and implemented according to the needs of the interdisciplinary project background, the demands of the stored data types and to recent metadata standards. The TRR228DB Metadata Schema is a structured list of metadata properties chosen to describe all data in the TRR228DB with accurate metadata to improve their searchability. It comprises a defined number of mandatory, optional and automatically generated metadata properties. The TRR228DB Metadata Schema is designed in compliance with Dublin Core Metadata Initiative and DataCite (Version 4.3) to achieve the interoperability with these metadata standards. Additionally, it is expanded with metadata elements from ISO 19115, INSPIRE, Data Documentation Initiative (DDI), as well as various properties appropriate to the stored data types and specific properties related to the CRC/TRR228 project background.

description: With the arrival of the big data era, mobility profiling has become a viable method of utilizing enormous amounts of mobility data to create an intelligent transportation system. Mobility profiling can extract potential patterns in urban traffic from mobility data and is critical for a variety of traffic-related applications. However, due to the high level of complexity and the huge amount of data, mobility profiling faces huge challenges. Digital Twin (DT) technology paves the way for cost-effective and performance-optimised management by digitally creating a virtual representation of the network to simulate its behaviour. In order to capture the complex spatio-temporal features in traffic scenario, we construct alignment diagrams to assist in completing the spatio-temporal correlation representation and design dilated alignment convolution network (DACN) to learn the fine-grained correlations, i.e., spatio-temporal interactions. We propose a digital twin mobility profiling (DTMP) framework to learn node profiles on a mobility network DT model. Extensive experiments have been conducted upon three real-world datasets. Experimental results demonstrate the effectiveness of DTMP.

Numerical modelling of the Abrasive Waterjet (AWJ) cutting process using Smoothed Particle Hydrodynamics (SPH) method
Creators: name: Budaraju, Siddharth
Publisher: name: University of British Columbia
Year: 2019

description: Computational fluid dynamics (CFD) is a valuable tool for the design or analysis of engineering processes in various industries. One such process is waterjet cutting, in which a high-pressure water jet mixed with abrasive is used to cut various materials. Alluvial garnet is an excellent abrasive, allowing cuts of 2 inches thickness or more, but due to its high cost, research into new, low-cost abrasives are needed. Metallurgical slag, a byproduct from smelting operations is found to be a promising abrasive alternative for waterjet cutting. However, slag has quite different material properties, particle size distributions, and flow characteristics than alluvial garnet, which can enhance or degrade the cut quality of the cut piece and/or experimental setup. A fundamental understanding of how the abrasive properties affect both the formation of the high-pressure jet and the material removal process is required. The main objective of the thesis is to develop a computational model of the waterjet cutting process that can provide an optimized parametric setup helping in better experiments. Challenges involved in modelling this problem constitute understanding flow characteristics such as the jet formation in the nozzle, multiphase (water and abrasive), compressibility, severe material distortions and deformations, which makes it very difficult to use mesh-based methods, such as finite element or finite volume. These complications can potentially be addressed through a mesh-free approach. Smoothed particle hydrodynamics (SPH) method, a Lagrangian-based meshless particle approach, approximates the differential terms as discrete summations based on kernel functions accounting for the weighted average influence of neighboring particles in the flow. Owing to the flexibility of its meshless formulation and generic applicability to various types of governing equations, SPH can be used to model the high-pressure jet, multiphase liquid/abrasive flow, and material removal process within a single unified modelling environment. This thesis will present the motivation, objectives and proposed methodology of the research, and will present a preliminary evaluation of the SPH methodology. An open-source SPH code, Python-based SPH code called PySPH, will also be discussed with an assessment of its accuracy and efficiency for compressible liquid flows, liquid/abrasive multiphase flows, and material removal processes.

description: In the context of averaging an inhomogeneous cosmological model, we propose a natural measure identical to the Kullback-Leibler relative information entropy, which expresses the distinguishability of the local inhomogeneous density field from its spatial average on arbitrary compact domains. This measure is expected to be an increasing function in time and thus to play a significant role in studying gravitational entropy. To verify this conjecture, we explore the time evolution of the measure using the linear perturbation theory of a spatially flat FLRW model and a spherically symmetric nonlinear solution. We discuss the generality and conditions for the time-increasing nature of the measure, and also the connection to the backreaction effect caused by inhomogeneities.

description: We study the quantum dynamics resulting from preparing a one-dimensional quantum system in the ground state of initially two decoupled parts which are then joined together (local quench). Specifically we focus on the transverse Ising chain and compute the time-dependence of the magnetization profile, m_l(t), and correlation functions at the critical point, in the ferromagnetically ordered phase and in the paramagnetic phase. At the critical point we find finite size scaling forms for the nonequilibrium magnetization and compare predictions of conformal field theory with our numerical results. In the ferromagnetic phase the magnetization profiles are well matched by our predictions from a quasi-classical calculation.

La testimonianza di vita delle religiose in Unione Sovietica (1945-1991)
Creators: name: Mirek Agata
Publisher: name: Zenodo
Year: 2017

description: Nel secondo dopoguerra i vertici dell’Impero sovietico si dedicarono con molto impegno alla realizzazione del piano di annientamento della religione e, in particolare, della Chiesa cattolica nei territori incorporati nel 1940 e divenuti parte integrante dell’URSS. Il processo interessò soprattutto le repubbliche occidentali, sorte dagli Stati baltici annessi all’Unione sovietica. Nelle “nuove” repubbliche occidentali, abitate da vari milioni di persone, le repressioni patite da tutte le comunità religiose furono molto brutali,ma colpirono particolarmente quelle cattoliche, presenti da secoli e, data la loro profonda coscienza religiosa e patriottica, animate da sentimenti ostili nei confronti dell’Unione Sovietica. La realtà dei fatti costrinse il regime comunista a tollerare le manifestazioni di vita religiosa sconosciute nel resto dell’Impero sovietico. Per la stessa ragione il programma e le procedure di eliminazione della Chiesa cattolica furono dilazionati nel tempo e significativamente diversificati a seconda della posizione geografica delle nuove repubbliche. In base a questa strategia, sorsero in territorio sovietico tre zone a differenziato tasso di libertà religiosa
CLIMATE CHANGE IMPACT ASSESSMENT ON SURFACE WATER  POTENTIAL IN UPPER AWASH BASIN: A CASE STUDY OF LEGEDADI - DIRE CATCHMENT
Creators: name: TSEGA WOLDESELASSIE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: In this study climate change impacts on surface water potential  at catchment scale  for the
two selected catchment in  Upper Awash Basin have  been assessed. The two catchments
included in the study were Legedadi (205 Km
2
) and Dire (77.56 Km
2
) catchments. A 0.44
by  0.44  degree  resolution  data  of  Coupled  Model  Inter-comparison  Phase5  (CMIP5)
global  climate  models  (GCMs)  output  of  precipitation  and  temperature  (maximum  and
minimum)  for  2020‟s  (2016-2035),  2050‟s  (2046-2065)  and  2080‟s  (2081-2100)  under
mid-range  Representative  Concentration  Pathway  (RCP  4.5)  were  applied  to  assess  the
climate  change  scenarios.  Bias  correction  was  applied  to  these  forcing  variables.
Moreover, a hydrological model,  Arc-SWAT,  was utilized to simulate runoff in the study
area.  Sensitivity  analysis  result  shown  that  Curve  Number  (CN)  factor  are  the  most
sensitive parameters affecting the hydrology of the catchment s. The model was calibrated
from 1988-1997 and  validated  from 1998-2003 at the estimated outlet of Legedadi and
Dire  catchment.  In  terms  of  hydrological  modeling  performance,  at  both  catchments
Nash-Sutcliffe (NSE)  indices are greater than 0.8  and  0.85 for calibration and  validation
period  respectively .  Future  projections  results  as  compared  to  base  period  (1986-2005)
have  shown  that,  the  annual  precipitation  exhibit  an  increasing  trend.    Maximum
increment  is  observed  for  2050s  projection  with  +11.9%  for  Legedadi  and  11.3%  for
Dire.  For  the  coming  90  years,  the  mean  monthly  precipitation  may  both  increase  and
decrease,  high  decrement  may  observe  during  (October  to  January )  months  and,  the
increment may observe on  (June to September)  months.  Legedadi has a range between  (-
27% and +25%), Where as Dire‟s range  is  between  (-63% and +32%).  The  mean  daily
temperature  increases  for  future  periods  (2020`s,  2050‟s,  and  2080`s)  with  maximum
increment of   +17% in 2080s.  In general in both study catchments; the impact of climate
change may cause an increase in annual runoff  for future periods. It may rise up to 14% in
Legedadi  and  17%  in  Dire  catchments  in  the  2050s.  Average  monthly  runo ff  increases
during Kermit  months  (wet  month)  and decrease  in Bega  months  (dry  month), ranging   in
between (+28% and  -33%)  in Legedadi  and (+29% and  -78%)  in Dire catchments.  High
Seasonal  mean  flow  may  be  observed  at  Kiremt   season  and  high  radiation  may  be
observed  on  Bega  season.  The  sensitivity  analysis  has  shown  that  both  catchments  are
more  sensitive to  rainfall. The  increase in  runoff  magnitude may  probably  have  positive
impacts in meeting the water supply demands to Addis Ababa city.
Distributed Creation and Adaptation of Random Scale-Free Overlay Networks

description: Random scale-free overlay topologies provide a number of properties like for example high resilience against failures of random nodes, small (average) diameter as well as good expansion and congestion characteristics that make them interesting for the use in large-scale distributed systems. A number of these properties have been shown to be influenced by the exponent γof their degree distribution P(k) ~ k^{-γ}. In this article, we present a distributed rewiring scheme that is suitable to effectuate scale-free overlay topologies with an adjustable exponent. The scheme uses a biased random walk strategy to sample new endpoints of edges being rewired and relies on a simple equilibrium model for scale-free networks. The bias of the random walk strategy can be tuned to produce random scale-free networks with arbitrary degree distribution exponents greater than two. We argue that the rewiring strategy can be implemented in a distributed fashion based on a node's information about its immediate neighbors. We present both analytical arguments as well as results that have been obtained using an implementation of the proposed protocol.

description: The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration. Specifically, we connect our modeling to neurotransmission in neural synapses where the diffusion of glutamate receptors is already known to refresh synaptic connections. We find that receptor diffusion indeed increases the accuracy of sensing for both the glutamate AMPA and NDMA receptors, although the NMDA receptor is overall much noiser. We propose that the difference in accuracy of sensing of the two receptors can be linked to their different roles in neurotransmission. Specifically, the high accuracy in sensing glutamate is essential for the AMPA receptor to start membrane depolarization, while the NMDA receptor is believed to work in a second stage as a coincidence detector, involved in long-term potentiation and memory.
