description: Due to the manifold connected devices future cellular based Internet of Things (IoT) networks require significant attention. Random point process (PP) based networks models are now widely accepted models for designing cellular based IoT networks because of theirs analytical tractability. This thesis focuses on analyzing the performance of cellular networks for massive connectivity of IoT devices using stochastic geometry. In cellular based IoT network, one of the key challenges resides in establishing connection between the devices and the base stations (BSs). An IoT device performs random access channel (RACH) procedure when it needs to establish connection with its intended BS. This thesis specifically focuses on the study of success of RACH access procedure for different BSs' distribution. In particular, we propose a novel generalized approach to calculate connection failure probability of IoT devices in RACH phase of uplink (UL) transmission. The proposed approach uses a calculation of the devices' association probability rather than an approximation of the Voronoi tessellation's cell area distribution. There are some limitations of using Voronoi tessellation based approach. This approach can only be used when the BSs are distributed according to Poisson point process (PPP). The merit of the proposed approach, besides its exact analysis, is that it can be applied for general scenarios of BSs' distributions. To adopt this approach, we derive the void probability for different Poisson cluster processes (PCP), in particular, Matérn cluster process (MCP) and Thomas cluster process (TCP), which is defined as the probability of having no children point of PCP in a given distance. First, we use our proposed mathematical approach to single-tier network. Next, we extend our mathematical framework in multi-tier cellular based IoT network. For both types of networks, we investigate the performance metrics using PPP and PCP distributions for BSs' deployment. We validate our approach with the numerical simulations via MATLAB. We vary different network parameters to see the effect in failure probability which can help network designers to set values of various design parameters. Numerical results demonstrate that our mathematical framework is highly accurate and adaptable for general scenarios.

description: Recommender systems have made significant strides in various industries, primarily driven by extensive efforts to enhance recommendation accuracy. However, this pursuit of accuracy has inadvertently given rise to echo chamber/filter bubble effects. Especially in industry, it could impair user's experiences and prevent user from accessing a wider range of items. One of the solutions is to take diversity into account. However, most of existing works focus on user's explicit preferences, while rarely exploring user's non-interaction preferences. These neglected non-interaction preferences are especially important for broadening user's interests in alleviating echo chamber/filter bubble effects.Therefore, in this paper, we first define diversity as two distinct definitions, i.e., user-explicit diversity (U-diversity) and user-item non-interaction diversity (N-diversity) based on user historical behaviors. Then, we propose a succinct and effective method, named as Controllable Category Diversity Framework (CCDF) to achieve both high U-diversity and N-diversity simultaneously.Specifically, CCDF consists of two stages, User-Category Matching and Constrained Item Matching. The User-Category Matching utilizes the DeepU2C model and a combined loss to capture user's preferences in categories, and then selects the top-$K$ categories with a controllable parameter $K$.These top-$K$ categories will be used as trigger information in Constrained Item Matching. Offline experimental results show that our proposed DeepU2C outperforms state-of-the-art diversity-oriented methods, especially on N-diversity task. The whole framework is validated in a real-world production environment by conducting online A/B testing.

description: Watershed  is  considered  to  be  the  ideal  unit  for  management  of  the  natural  resources.  Extraction
of  watershed  parameters  using  Remote  Sensing  and  Geographical  Information  System  (GIS)  and
use  of  mathematical  models  is  the  current  trend  for  hydrologic  evaluation  of  watersheds.  Soil
erosion  is  a  serious  threat  in  the  Guder  watershed.  Deforestation,  overgrazing,  and  poor  land
management  accelerated  the  rate  of  erosion.  To  develop  effective  erosion  control  plans  and  to
achieve  reductions  in  sedimentation,  it  is  important  to  quantify  the  sediment  yield  and  identify
areas  that  are  high  contributors  of  sediment  at  micro- watershed  level  and  over  large  areas.  In this
study  SWAT   (Soil  and  Water  Assessment  Tool)  having  an  interface  with  ArcView  GIS  software
was  used  to  estimate  sediment  yield  and  identify  spatial  distribution  of  sediment  yield  in  the
watershed.  The  model  was  successfully  calibrated  and  validated  for  measured  stream   flow  and
suspended  sediment  concentration   at  Guder  gauging  stations.  The  calibration  and  validation
result  showed  that  model  performance  evaluation  statistics  (coefficient  of  determination   (R
2
)  and
Nash- Sutcliffe  model  efficiency  (E
NS ))  were  in  the  acceptable  range  (R
2
in  the  range  0.85 to 0.89
and  E
NS   in  the  range  0.72  to  0.79).  This  indicates  that  the  observed values  show good agreement
with  simulated  value  for  both  flow  and  sediment  yield.  The  model  prediction  result  shown  that
the  annual  sediment  yield  leaving  the  watershed  was  found   to  be  5,319,678  ton/yr.  It  was
5,113,088  ton /yr.  by  rating  curve  generation .  The  model  prediction  results  indicated  that  about
8.9%  of  the  watershed  areas  severely  eroded  with   annual  sediment  load  ranging  from  18  to
35ton es/ha/yr.  and  about  21.7%  of  the  watershed  area  has  high  erosion  with  annual  sediment
load  ranging  12  to  17tones/ha/yr.   The  annual  average  sediment  yield  of  the  watershed  was
8.26t/ha/yr.  and  total  of  5.32  m illion  tons  of  sediment  yield  was  leaving  the  G uder  watershed
annually.   The  result  of  the  study  could  help  different  stakeholders  to  plan  and  implement
appropriate  soil  and water conservation  strategies  in the watershed.

description: We use a combination of original light scattering techniques and particles with unique optical properties to investigate the behavior of suspensions of attractive colloids under gravitational stress, following over time the concentration profile, the velocity profile, and the microscopic dynamics. During the compression regime, the sedimentation velocity grows nearly linearly with height, implying that the gel settling may be fully described by a (time-dependent) strain rate. We find that the microscopic dynamics exhibit remarkable scaling properties when time is normalized by strain rate, showing that the gel microscopic restructuring is dominated by its macroscopic deformation.

description: One of the most striking features of quantum mechanics is the appearance of phases of matter with topological origins. These phases result in remarkably robust macroscopic phenomena such as the edge modes in integer quantum Hall systems, the gapless surface states of topological insulators, and elementary excitations with non-abelian statistics in fractional quantum Hall systems and topological superconductors. Many of these states hold promise in the applications to quantum memories and quantum computation. Artificial quantum systems, with their precise controllability, provide a versatile platform for creating and probing a wide variety of topological phases. Here we investigate topological phenomena in one dimension, using photonic quantum walks. The photon evolution simulates the dynamics of topological phases which have been predicted to arise in, for example, polyacetylene. We experimentally confirm the long-standing prediction of topologically protected localized states associated with these phases by directly imaging their wavefunctions. Moreover, we reveal an entirely new topological phenomenon: the existence of a topologically protected pair of bound states which is unique to periodically driven systems. Our experiment demonstrates a powerful new approach for controlling topological properties of quantum systems through periodic driving.

description: Robotic assistants reduce the manual efforts being put in by humans in their day-to-day tasks. In this paper, we develop a voice-controlled personal assistant robot. The robot takes the human voice commands by its own built-in microphone. This robot not only takes the commands and executes them but also acknowledges them through speech output. This robot can perform different movements, turns, wakeup/shutdown operations, relocate an object from one place to another, and can also develop a conversation with humans. The voice commands are processed in real time using an offline server. The speech signal commands are directly communicated to the server using a USB cable. The personal assistant robot is developed on a microcontroller-based platform. Performance evaluation is carried out with encouraging results of the initial experiments. Possible improvements for applications in homes, hospitals, car systems, and industries are also discussed.

PERFORMANCE EVALUATION OF ALIFIF MEDIUM SCALE IRRIGATION   SCHEME IN EAST HARARGHE
Creators: name: SHAMSUDIN KELIL
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Ethiopia  is one of sub-Saharan  Africa country, in which rain-fed agriculture is the mainstay of
the  rural  population.  One  of  the  challenges  Ethiopia  is  facing  in  attaining  food  security  and
reducing poverty is high dependence on rain fed agriculture. To achieve food self-sufficiency,
use of the available water resource for irrigation development is the most promising option.  The
Alfif irrigation project operates under a low level of performance due to poor water management
and  lack  of  timely  maintenance  of  structures.The  aim  of  this  research  was  to  evaluate  the
performance  of  the  Alifif  irrigation  scheme  using  performance  indices  such  as  application
efficiency (Ea), conveyance efficiency (Ec), storage efficiency (Es), distribution uniformity (DU)
and  outputs  per  units  of  land  and  water  used.  Overall  activities  in  primary  data  collected
included:  field  observation,  interviewing  beneficiary  farmers,  discharge  measurements  in  the
canals, determination of moisture contents of the soil before and after irrigation, determination of
soil physical properties and measurement of depth of water  applied to the fields.  Secondary data
were  also  collected from the  secondary sources.  For technical evaluation of  both  left and right
schemes using performance indices, six farmers‘ fields were selected each from the head, middle
and tail-end water users.  Conveyance efficiencies of the Left and Right main canals  for distance
of 2650m were 55.85 % and 53.1 % respectively. Conveyance losses on primary canals were due
to spillage, seepage and overtopping from conveyance systems.  Relative water supply for crops
are 2.4 on left and 2.5 on right canal indicates over supply of water for crops that have impact on
yield reduction. Relative irrigation water supply is 2.9 on left and 3.1 on right that is greater than
unity indicates unwise use of resource.  The head, middle and tail-ends application efficiencies
were in the range of 23.77 to 65.0 %. The losses were due to deep percolation as the basins are
ridged  from  all  sides.  Delivery  of  water  in  the  scheme  showed  that  there  was  inequitable
distribution in each head, middle, and tail reaches of canal  system.  Increasing  of water turn, the
type of irrigation system used, the ridged irrigation practice and the poor irrigation scheduling in
the  study  sites  were  the  main  problems  identified  in  the  management  and  operations  of  the
schemes;  which  causes  the  under-  performance  of  the  scheme.  To  improve  the  system,  the
corrective measures of previous problems, Proper design and layout of canals, on-farm training
farmers and improvement of the physical structures of the scheme are essential.

description: We report a new reversal mechanism of magnetic vortex cores in nanodot elements driven by out-of-plane currents, occurring through two coupled edge-solitons via dynamic transformations between magnetic solitons of different topological charges. This mechanism differs completely from the well known switching process mediated by the creation and annihilation of vortex-antivortex pairs in terms of the associated topological solitons, energies, and spin-wave emissions. Strongly localized out-of-plane gyrotropic fields induced by the fast motion of the two coupled edge-solitons enable a magnetization dip that plays a crucial role in the formation of the reversed core magnetization. This work provides a new physical insight into the dynamic transformations of magnetic solitons in nanoelements.

description: Thesis for MSc Science Communication.
Considering the immense impacts that science and society have on each other, the relationship between science and ‘the public’ deserves a great deal of attention. Through exploring the power dynamics behind the dominant, pervasive deficit model of public engagement with science, I uncover why it is harmful for both citizens and scientists, focusing on how undemocratic decision making about the direction of scientific research widens societal inequalities.
 Reflecting on these issues, I explore the questions: what is responsive science, what are its benefits and what needs to be in place for it to occur? how can public engagement practitioners facilitate dialogue, so that scientists can better understand citizen needs?
 I use the AccessLab project to help answer these questions, combining extensive research with details about the format of the project and testimony from interviews I conducted with two scientist and two citizen participants in the workshops.
 This analysis exposed several ways that the project challenged the concerning, out-dated assumptions underlying public engagement with science. Firstly, the pitching of science as a service to citizens stressed the importance of ensuring science is not only relevant but responsive to citizen needs. Secondly, the project demonstrated how to challenge transmission models of communication within current constraints, through disseminating research skills, emphasising the skills of scientists over their expertise, and theming citizen participant groups. Thirdly, through careful consideration about the makeup and size of groups as well as the format and environment of the workshops, AccessLabs displayed several ways of easing dialogue between citizens and scientists. Finally, AccessLabs demonstrates how essential it is to adopt experimental, open, and critical approaches to public engagement if practices are to move forward and become more useful for citizens.

description: We present exact formulas for the entanglement and Rényi entropies generated at a quantum point contact (QPC) in terms of the statistics of charge fluctuations, which we illustrate with examples from both equilibrium and non-equilibrium transport. The formulas are also applicable to groundstate entanglement in systems described by non-interacting fermions in any dimension, which in one dimension includes the critical spin-1/2 XX and Ising models where conformal field theory predictions for the entanglement and Rényi entropies are reproduced from the full counting statistics. These results may play a crucial role in the experimental detection of many-body entanglement in mesoscopic structures and cold atoms in optical lattices.

description: Irrigation scheme performance assessment is vital to evaluate the impacts of irrigation
practices, to identify performance gaps and to improve system performances. However,
the performance of Jari and Aloma Small Scale Irrigation (SSI) schemes was not assessed
since its operation. Therefore, this study was carried out to evaluate the water delivery,
on-farm  water  management  and  organizational  performances  of the  two SSI  schemes.
Secondary  data  from  different reports and  primary  data  through  field  measurements,
household  surveys,  key  informant  interviews  and  group  discussions  were  collected.
CROPWAT 8.0 model, SPSS and GIS software were used to analyze the data. The result
of this study revealed that, the overall canal water delivery efficiencies of Jari and Aloma
SSI schemes were 66% and 59%, respectively. Majority of the respondents, 37% in Jari
and 61.9% in Alom, reflected that the maintenance condition of irrigation infrastructures
was bad. From the respondents 45.5% in Jari and 50% in Aloma described that illegal
water abstraction accounts the primary cause for unfair water distributions. The ratios of
relative water supply and the relative irrigation water supply were almost equal to 1 at
both SSI schemes. This implied that the amount of water supplied was sufficient for the
water demand  of  the  schemes.  Output  per  unit  irrigated  area  values  of  2198$/ha  and
1356$/ha were calculated at Jari and Aloma SSI schemes, respectively. Furthermore, the
output per unit command area of Jari (3464$/ha) was three fold higher than the value of
Aloma  (1061$/ha).  Water  productivity  indicators  such  as,  Output  per  unit  irrigation
water supplied (OPUIS), Output per unit irrigation water delivered (OPUID) and Output
per  unit  water consumed  (OPUWC)  values  of 0.47$/m

and  0.2$/m

in  Aloma  schemes  were  calculated,  respectively.
Irrigation intensity ratio in Jari (174%) was much higher than Aloma (78%). The original
irrigable areas were declined by 14% in 3 years and 39% in 10 years operation periods
in Jari and Aloma schemes, respectively. The main reasons for low output production in
Aloma  scheme  were  low  irrigation  intensity,  grown  low  value  crops.  Generally  the
performance of Jari is better than Aloma SSI schemes.

Using recently obtained potential energy and permanent dipole moment surfaces of H$_3^-$, we calculate the lowest rovibrational levels of the H$_3^-$ electronic ground state, and the cross section for the formation of H$_3^-$ by radiative association between H$^-$ and ortho- and para-H$_2$. We discuss the possibility for the H$_3^-$ ion to be formed and observed in the cold and dense interstellar medium in an environment with a high ionization rate. Such an observation would be a probe for the presence of H$^-$ in the interstellar medium.

description: Graphs and feature functions on graphs provide a comprehensive framework for handling discrete data and play an increasingly important role in many areas of applied mathematics. The graph framework provides many tools, in particular the graph Laplacian operator ubiquitous both in the general study of graphs and in application. Graphs are, however, limited to the modeling using pairwise connections. This has motivated the use of hypergraphs, a generalization of graphs that can represent arbitrarily $N$-ary interactions and relationships directly with their hyperedges. To define a hypergraph framework, as with graphs, one aims to define feature functions and function spaces on the nodes and edges. The feature spaces then show up as the codomains of these functions and are in the majority of cases Euclidean of some dimension. In this case, many hypergraph Laplacians have been proposed in the literature. While effective for many problems, there are others where features are more naturally represented as points in a more general manifold. This work generalizes previous hypergraph approaches to accommodate such manifold-valued data for many commonly encountered manifolds, taking their Riemannian geometrical structure into account. In particular, we introduce two frameworks of manifold-valued hypergraph functions, each including its families of isotropic and anisotropic $p$-Laplacians generalizing hypergraph Laplacians of existing literature.

description: The research interest on location-based services has increased during the last years ever since 3D centimetre accuracy inside intelligent environments could be confronted with. This work proposes an indoor local positioning system based on LED lighting, transmitted from a set of beacons to a receiver.The receiver is based on a quadrant photodiode angular diversity aperture (QADA) plus an aperture placed over it.This configuration can be modelled as a perspective camera, where the image position of the transmitters can be used to recover the receiver's 3D pose. This process is known as the perspective-n-point (PnP) problem, which is well known in computer vision and photogrammetry. This work investigates the use of different state-of-the-art PnP algorithms to localize the receiver in a large space based on four co-planar transmitters and with a distance from transmitters to receiver of 3.4 m. Encoding techniques are used to permit the simultaneous emission of all the transmitted signals and their processing in the receiver. In addition, correlation techniques are used to determine the image points projected from each emitter on the QADA. This work uses Monte Carlo simulations to characterize the absolute errors for a grid of test points under noisy measurements, as well as the robustness of the system when varying the 3D location of one transmitter. The IPPE algorithm obtained the best performance in this configuration. The proposal has also been experimentally evaluated in a real setup. The estimation of the receiver's position at three points using the IPPE algorithm achieves average absolute errors of 4.33cm, 3.51cm and 28.90cm in the coordinates x, y and z, respectively. These positioning results are in line with those obtained in previous work using triangulation techniques but with the addition that the complete pose of the receiver is obtained in this proposal.

NK Hybrid Genetic Algorithm for Clustering

description: The NK hybrid genetic algorithm for clustering is proposed in this paper. In order to evaluate the solutions, the hybrid algorithm uses the NK clustering validation criterion 2 (NKCV2). NKCV2 uses information about the disposition of $N$ small groups of objects. Each group is composed of $K+1$ objects of the dataset. Experimental results show that density-based regions can be identified by using NKCV2 with fixed small $K$. In NKCV2, the relationship between decision variables is known, which in turn allows us to apply gray box optimization. Mutation operators, a partition crossover, and a local search strategy are proposed, all using information about the relationship between decision variables. In partition crossover, the evaluation function is decomposed into $q$ independent components; partition crossover then deterministically returns the best among $2^q$ possible offspring with computational complexity $O(N)$. The NK hybrid genetic algorithm allows the detection of clusters with arbitrary shapes and the automatic estimation of the number of clusters. In the experiments, the NK hybrid genetic algorithm produced very good results when compared to another genetic algorithm approach and to state-of-art clustering algorithms.

Does Quantum Mechanics Clash with the Equivalence Principle - and Does it Matter?

description: With an eye on developing a quantum theory of gravity, many physicists have recently searched for quantum challenges to the equivalence principle of general relativity. However, as historians and philosophers of science are well aware, the principle of equivalence is not so clear. When clarified, we think quantum tests of the equivalence principle won't yield much. The problem is that the clash/not-clash is either already evident or guaranteed not to exist. Nonetheless, this work does help teach us what it means for a theory to be geometric.

description: The properties of the superconducting state in calcium under the pressure at 120 GPa were analyzed. By using the imaginary axis Eliashberg equations it has been shown, that the Coulomb pseudopotential reaches the high value equal to 0.215. In the considered case, the critical temperature is not properly described by the Allen-Dynes formula and it should be calculated with an use of the modified expression. In the paper the exact solutions of the Eliashberg equations on the real axis were also obtained. On this basis it was stated, that the effective potential of the electron-electron interaction is attractive for the frequencies lower or equal to the maximum phonon frequency. Then, the dimensionless parameter 2Δ(0)/k_{B}T_{C}=4.10 was calculated. In the last step it has been proven, that the ratio of the electron effective mass to the bare electron mass is high and reaches its maximum equal to 2.36 for the critical temperature.
