Creators: name: Ali, Mohammed
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Cross-border livestock trade is an important livelihood activity for many pastoral and agropastoral communities in the Horn of Africa. The Objective of the study were to examine the challenges and its policy implications of cross border livestock trade along the border of Somali regional state of Ethiopia with Somaliland. The main target population of this study includes livestock producers, livestock traders and livestock exporters of the three districts namely (Togwajale, Kebribeyah and Awbare) via Togwjale trade routes in the Somali regional state of Ethiopia with Somaliland. These Districts are purposely selected to the evidence that, they are located along the outlet and strong potentials for both domestic and cross border livestock trading. The study was relied on both quantitative and qualitative data collected from primary and secondary sources. The primary data for this study was collected with the aid of close-ended and open-ended questionnaire. The Secondary data for this study was collected from Custom Revenue Authority of Jigjig town, related literatures, annual reports, National livestock trading policies, custom office of the outlet, Regional trade bureau, and livestock-marketing department of the region. In addition, checklist interview was designed to Key-informants. Furthermore, the challenges and policy implications of cross border livestock trading was analyzed and presentedin tabulations and graphs. On the other hand, narrative type of analysis was used to illustrate qualitative information. Finally, recommendations are given based on the findings of the study.

description: It seems that the wealth of information revealed by the multi-messenger observations of the binary neutron star (NS) merger event, GW170817/GRB 170817A/kilonova AT2017gfo, places irreconcilable constraints to models of the prompt emission of this gamma-ray burst (GRB). The observed time delay between the merger of the two NSs and the trigger of the GRB and the thermal tail of the prompt emission can hardly be reproduced by these models simultaneously. We argue that the merger remnant should be an NS (last for, at least, a large fraction of 1s), and that the difficulty can be alleviated by the delayed formation of the accretion disk due to the absorption of high-energy neutrinos emitted by the NS and the delayed emergence of an effective viscous in the disk. Further, we extend the consideration of the effect of the energy deposition of neutrinos emitted from the NS. If the NS is the central object of a GRB with a distance and duration similar to that of GRB 170817A, thermal emission of the thermal bubble inflated by the NS after the termination of accretion may be detectable. If our scenario is verified, it would be of interest to investigate the cooling of nascent NSs.

description: Tourism which is regarded as information intensive sector is the mostly affected sector by technology revolution and its traditional trading structures have been totally changed. The adoption and use of e-commerce in tourism sector is regarded as a tool to widen market reach and improve efficiency and effectiveness of business operations. This study considers e-commerce adoption by TOs in Ethiopia. This study is motivated by the fact that the adoption of e-commerce by tourism sector, especially in Ethiopia, is very important but still very farbehind. This study used TAM, innovation diffusion; e-readiness theories identified nine factorsas the determinant factors of e-commerce adoption, which are top management support,organizational competency, IT capacity, perceived benefits, perceived compatibility, perceivedcomplexity, market e-readiness, supporting industry and government e-readiness. A surveywas conducted with 217 Ethiopian tour operators that have already been listed by MoTC.SPSS was used to analyze the data. . The findings indicated that All variables have a positiveand significant correlation. Based on multiple linear regression analysis, it reveals that theimpact of each determining factors in e-commerce adoption and their significance. The impactof Market E-Readiness, IT Capability, Perceived Benefit, Supporting industries,Organizational Competency, Government E-Readiness, Perceived Compatibility, Topmanagement support and Perceived Complexity on e-commerce adoption with Tour operatorsin Ethiopia in their descending order. By examining this beta weight of data analysis result thefinding shown that Market e-readiness followed by IT Capability and Perceived Benefit wasmaking relatively larger contribution to the prediction model. The model summary reveals that the proportion of the variation in e-commerceAdoption is explained by the nine independent variables collectively are 92.2% andthe remaining 7.8% of the variance is explained by other variables This thesismakes a contribution to theory and practice by providing for Ethiopian tourism in particularto TOs , a holistic picture of e-commerce adoption; the extent of e-commerce adoption; and,the determinant factors leading to adoption.

description: The occurrence and frequency of a phenomenon of resonance (namely the coalescence of some Dubrovin canonical coordinates) in the locus of Small Quantum Cohomology of complex Grassmannians is studied. It is shown that surprisingly this frequency is strictly subordinate and highly influenced by the distribution of prime numbers. Two equivalent formulations of the Riemann Hypothesis are given in terms of numbers of complex Grassmannians without coalescence: the former as a constraint on the disposition of singularities of the analytic continuation of the Dirichlet series associated to the sequence counting non-coalescing Grassmannians, the latter as asymptotic estimate (whose error term cannot be improved) for their distribution function.

description: The GAIA space mission is impacting astronomy in many significant ways by providing a uniform, homogeneous and precise data set for over 1 billion stars and other celestial objects in the Milky Way and beyond. Exoplanet science has greatly benefited from the unprecedented accuracy of stellar parameters obtained from GAIA. In this study, we combine photometric, astrometric, and spectroscopic data from the most recent Gaia DR3 to examine the kinematic and chemical age proxies for a large sample of 2611 exoplanets hosting stars whose parameters have been determined uniformly. Using spectroscopic data from the Radial Velocity Spectrometer (RVS) onboard GAIA, we show that stars hosting massive planets are metal-rich and $α$-poor in comparison to stars hosting small planets. The kinematic analysis of the sample reveals that the stellar systems with small planets and those with giant planets differ in key aspects of galactic space velocity and orbital parameters, which are indicative of age. We find that the galactic orbital parameters have a statistically significant difference of 0.06 kpc for $Z_{max}$ and 0.03 for eccentricity respectively. Furthermore, we estimated the stellar ages of the sample using the MIST-MESA isochrone models. The ages and its proxies for the planet-hosting stars indicate that the hosts of giant planetary systems are younger compared to the population of stars harboring small planets. These age trends are also consistent with the chemical evolution of the galaxy and the formation of giant planets from the core-accretion process.

description: A canonical Hamiltonian is found for a reduced version of the Jackiw-Pi model for bilayer graphene. From the corresponding Lagrangian, the Noether point symmetries and conserved quantities are determined. The Noether symmetry group is the same as the fifth-dimensional group for the time-dependent harmonic oscillator. The realization of the algebra is achieved in terms of just one particular solution $g_1$ of the time-dependent harmonic oscillator equation underlying the reduced Jackiw-Pi model. Some numerical solutions are worked out.

Please cite this paper as: Amirhossein Tavanaei, Timothee Masquelier, and Anthony Maida, Acquisition of visual features through probabilistic spike-timing-dependent plasticity. IEEE International Joint Conference on Neural Networks. pp. 307-314, IJCNN 2016. This paper explores modifications to a feedforward five-layer spiking convolutional network (SCN) of the ventral visual stream [Masquelier, T., Thorpe, S., Unsupervised learning of visual features through spike timing dependent plasticity. PLoS Computational Biology, 3(2), 247-257]. The original model showed that a spike-timing-dependent plasticity (STDP) learning algorithm embedded in an appropriately selected SCN could perform unsupervised feature discovery. The discovered features where interpretable and could effectively be used to perform rapid binary decisions in a classifier. In order to study the robustness of the previous results, the present research examines the effects of modifying some of the components of the original model. For improved biological realism, we replace the original non-leaky integrate-and-fire neurons with Izhikevich-like neurons. We also replace the original STDP rule with a novel rule that has a probabilistic interpretation. The probabilistic STDP slightly but significantly improves the performance for both types of model neurons. Use of the Izhikevich-like neuron was not found to improve performance although performance was still comparable to the IF neuron. This shows that the model is robust enough to handle more biologically realistic neurons. We also conclude that the underlying reasons for stable performance in the model are preserved despite the overt changes to the explicit components of the model.

Super-Resolution Delay-Doppler Estimation for OFDM Passive Radar
Creators: name: Zheng, Le
name: Wang, Xiaodong
Publisher: name: arXiv
Year: 2016
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this paper, we consider the problem of joint delay-Doppler estimation of moving targets in a passive radar that makes use of orthogonal frequency-division multiplexing (OFDM) communication signals. A compressed sensing algorithm is proposed to achieve supper-resolution and better accuracy, using both the atomic norm and the $\ell_1$-norm. The atomic norm is used to manifest the signal sparsity in the continuous domain. Unlike previous works which assume the demodulation to be error free, we explicitly introduce the demodulation error signal whose sparsity is imposed by the $\ell_1$-norm. On this basis, the delays and Doppler frequencies are estimated by solving a semidefinite program (SDP) which is convex. We also develop an iterative method for solving this SDP via the alternating direction method of multipliers (ADMM) where each iteration involves closed-form computation. Simulation results are presented to illustrate the high performance of the proposed algorithm.

According to that hypothesis interviewing methods that impose cognitive load can expose lies versus truths (e.g., Vrij & Granhag, 2012). Previously, I single-handedly extracted and thematized those justifications (Neequaye, 2021 [see Supplemental Table, Preprint Version 3]). This registration is to specify the process to ascertain the reliability of my previous coding.

description: We demonstrate an experimental technique for both transverse and longitudinal characterization of bunched femtosecond free electron beams. The operation principle is based on monitoring of the current of electrons that obtained an energy gain during the interaction with the synchronized optical near-field wave excited by femtosecond laser pulses. The synchronous accelerating/decelerating fields confined to the surface of a silicon nanostructure are characterized using a highly focused sub-relativistic electron beam. Here the transverse spatial resolution of 450 nm and femtosecond temporal resolution achievable by this technique are demonstrated.

description: One of the most interesting puzzles in particle physics today is that new physics is expected at the TeV energy scale to solve the hierarchy problem, and stabilise the Higgs mass, but so far no unambiguous signal of new physics has been found. Strong constraints on the energy scale of new physics can be derived from precision tests of the electroweak theory and from flavour-changing or CP-violating processes in strange, charm and beauty hadron decays. Decays that proceed via flavour-changing-neutral-current processes are forbidden at the lowest perturbative order in the Standard Model and are, therefore, rare. Rare $b$ hadron decays are playing a central role in the understanding of the underlying patterns of Standard Model physics and in setting up new directions in model building for new physics contributions. In this article the status and prospects of this field are reviewed.

description: Observations from space missions have allowed significant progress in many scientific domains due to the absence of atmospheric noise contributions and having uninterrupted data sets. In the context of asteroseismology, this has been extremely beneficial because many oscillation frequencies with small amplitudes, not observable from the ground, can be detected. One example of this success is the large number of hybrid delta Sct-gamma Dor stars discovered. These stars have radial and non-radial p- and g-modes simultaneously excited to an observable level allowing us to probe both the external and near-to-core layers of the star. We analyse the light curve of hybrid delta Sct-gamma Dor star CoRoT ID 102314644 and characterise its frequency spectrum. We detected 29 gamma Dor type frequencies in the range [0.32-3.66] cycles per day (c/d) and a series of 6 equidistant periods with a mean period spacing of DeltaPi=1612 s. In the delta Sct domain we found 38 frequencies in the range 8.63-24.73 c/d and a quintuplet centred on the frequency p_1=11.39 c/d and derived a possible rotational period of 3.06 d. The frequency analysis of this object suggests the presence of spots at the stellar surface, nevertheless we could not dismiss the possibility of a binary system. The initial modelling of the frequency data along with external constraints has allowed us to refine its astrophysical parameters giving a mass of approximately 1.75 solar masses, a radius of 2.48 solar radii and an age of 1241 Myr. The observed period spacing, a p-mode quintuplet, the possible rotation period and the analysis of the individual frequencies provide important input constraints for the understanding of different transport phenomena in A-F-type stars.[abridged]

The Status of Ethiopia's Inter-country Adoption Policy Implementation: the Case of Key Stakeholders in Intercountry Adoption Process
Creators: name: Getachew, Daniel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The main objective of the study is to investigate the challenges of intercountry adoption and come up with feasible policy alternatives that can contribute to the implementation of child rights in the country. A qualitative study is used which included both primary and secondary data. In order to achieve the results, purposive sampling is used in identifying and selecting appropriate organizations and respondents in the study. Relevant information was collected through key informant interview from experts of MoWCYA and four nongovernment organizations (2 local and 2 international). Data thematically organized and analysed qualitatively based upon logical and descriptive analysis. The study was able to find out that the Ethiopian government has adopted different policies and conventions on the right of children. Despite some notable progresses, child fundamental rights have remained major challenges in the country.Legislatives/policies introduced over the past years have not made significant difference to the implementation of alternative child care packages. Systemic inadequacies, illegal financial gains and corruption, child trafficking, buying selling, and abducting and falsification of documents have been recognized as major problems facing in the intercountry policy implementation. Therefore, effective implementation, monitoring and evaluation of pro-children policies/legislative have sought to decrease the prevalence of the problems. Wherever and whenever intercountry adoption is applied as a measure of last resort and before institutional care, it should be carried out based on the principle of the best interest of the child

description: BRST quantization is an elegant and powerful method to quantize theories with local symmetries. In this article we study the Hamiltonian BRST quantization of cosmological perturbations in a universe dominated by a scalar field, along with the closely related quantization method of Dirac. We describe how both formalisms apply to the perturbations in a time-dependent background, and how expectation values of gauge-invariant operators can be calculated in the in-in formalism. Our analysis focuses mostly on the free theory. By appropriate canonical transformations we simplify and diagonalize the free Hamiltonian. BRST quantization in derivative gauges allows us to dramatically simplify the structure of the propagators, whereas quantization in synchronous gauge, which amounts to Dirac quantization, dispenses with the need to introduce ghosts and preserves the locality of the gauge-fixed action.

description: NEID is a high-resolution red-optical precision radial velocity (RV) spectrograph recently commissioned at the WIYN 3.5 m telescope at Kitt Peak National Observatory, Arizona, USA. NEID has an extremely stable environmental control system, and spans a wavelength range of 380 to 930 nm with two observing modes: a High Resolution (HR) mode at R $\sim$ 112,000 for maximum RV precision, and a High Efficiency (HE) mode at R $\sim$ 72,000 for faint targets. In this manuscript we present a detailed description of the components of NEID's optical fiber feed, which include the instrument, exposure meter, calibration system, and telescope fibers. Many parts of the optical fiber feed can lead to uncalibratable RV errors, which cannot be corrected for using a stable wavelength reference source. We show how these errors directly cascade down to performance requirements on the fiber feed and the scrambling system. We detail the design, assembly, and testing of each component. Designed and built from the bottom-up with a single-visit instrument precision requirement of 27 $\textrm{cm~s}^{-1}$, close attention was paid to the error contribution from each NEID subsystem. Finally, we include the lab and on-sky tests performed during instrument commissioning to test the illumination stability, and discuss the path to achieving the instrumental stability required to search for a true Earth twin around a Solar-type star.

description: Gravitational lensing provides unique insights into astrophysics and cosmology, including the determination of galaxy mass profiles and constraining cosmological parameters. We present spectroscopic confirmation and lens modeling of the strong lensing system DESI-253.2534+26.8843, discovered in the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys data. This system consists of a massive elliptical galaxy surrounded by four blue images forming an Einstein Cross pattern. We obtained spectroscopic observations of this system using the Multi Unit Spectroscopic Explorer (MUSE) on ESO's Very Large Telescope (VLT) and confirmed its lensing nature. The main lens, which is the elliptical galaxy, has a redshift of $z_{L1} = 0.636\pm 0.001$, while the spectra of the background source images are typical of a starburst galaxy and have a redshift of $z_s = 2.597 \pm 0.001$. Additionally, we identified a faint galaxy foreground of one of the lensed images, with a redshift of $z_{L2} = 0.386$. We employed the GIGA-Lens modeling code to characterize this system and determined the Einstein radius of the main lens to be $θ_{E} =2.520{''}_{-0.031}^{+0.032}$, which corresponds to a velocity dispersion of $σ$ = 379 $\pm$ 2 km s$^{-1}$. Our study contributes to a growing catalog of this rare kind of strong lensing systems and demonstrates the effectiveness of spectroscopic integral field unit observations and advanced modeling techniques in understanding the properties of these systems.

Three-nucleon bound states and the Wigner-SU(4) limit

description: We examine the extent to which the properties of three-nucleon bound states are well-reproduced in the limit that nuclear forces satisfy Wigner's SU(4) (spin-isospin) symmetry. To do this we compute the charge radii up to next-to-leading order (NLO) in an effective field theory (EFT) that is an expansion in powers of $R/a$, with $R$ the range of the nuclear force and $a$ the nucleon-nucleon ($N\!N$) scattering lengths. In the Wigner-SU(4) limit, the triton and Helium-3 point charge radii are equal. At NLO in the range expansion both are $1.66$ fm. Adding the first-order corrections due to the breaking of Wigner symmetry in the $N\!N$ scattering lengths gives a ${}^3\mathrm{H}$ point charge radius of $1.58$ fm, which is remarkably close to the experimental number, $1.5978\pm0.040$ fm (Angeli and Marinova in At Data Nucl Data Tables 99:69-95, 2013). For the ${}^3\mathrm{He}$ point charge radius we find $1.70$ fm, about 4% away from the experimental value of $1.77527\pm0.0054$ fm (Angeli and Marinova 2013). We also examine the Faddeev components that enter the tri-nucleon wave function and find that an expansion of them in powers of the symmetry-breaking parameter converges rapidly. Wigner's SU(4) symmetry is thus a useful starting point for understanding tri-nucleon bound-state properties.

description: The conventional electromagnetic forming processing can’t shape large parts due to limitation of the strength of working coil and the capacity of capacitor bank. In this paper, a novel technology named electromagnetic-incremental forming (EMIF) has been proposed. A small working coil moves along the special motion trail and many small electromagnetic pulses energy are used to form a larger aluminum alloy sheet. The effect of vent holes, discharge voltage on sheet final profiles are analyzed. In addition, two discharge times with varying value of discharge voltage is used to obtain better final sheet profiles. The effect of the previous discharge on the second one is also analyzed. Then, a 3D sequential coupling method is used to calculate the magnetic force on the sheet and analyze the forming process. In the latter deformation, the deformation information is also considered from the former one, such as the deflection, velocity, stress, strain, et al. The simulation values are in better agreement with the experimental ones. This work demonstrates that the new technology offers an ability to form large and complex components with a small working coil and small discharging energy of the electromagnetic machine. Moreover, the simulation method can be used for more complex forming system.

description: Forming limit diagrams are an essential tool for describing the formability of sheet materials in the deep-drawing process. Here, the well known and frequently employed procedures are the Nakajima and the Marciniak-Tests. Whereas these procedures' standardisation is quite advanced in the quasi-static range, numerous different test procedures exist in the range of elevated forming speeds. In the first part of this work, an overview of the various procedures is given for generating forming limit diagrams in the high speed range. In the second part, a pneumatically operated testing device is introduced which was developed at the Institute for Material Science for performing Nakajima-Tests in the high speed range. Using this device, standard specimens can be dynamically formed according to the Nakajima-Test. The testing device is to be employed for scientifically exploring the deformation mechanisms operating at very high forming speeds. The testing device’s mode of functioning is demonstrated by means of forming discs of an EN AW-6082 aluminium alloy sheet. In doing this, the testing apparatus is mainly characterised by holding the testing conditions constant during the tests: This particularly concerns the velocity of the tool for forming the sheet discs.
Comparative Study of Performance Management and Reward Practices Between Privatized and Public Enterprises: Cases of Addis Ababa Tannery S.C. and Anbessa Shoe S.C.

description: This comparative case study compares the performance management and reward practiced being followed by Addis Ababa Tannery Share Company (privatized enterprise) and Anbessa Shoe Share Company (state owned). Its main objective was to investigate the differences in applying the different performance management and rewarding mechanisms. It also addressed the similarities and deviations in what the policy documents in those enterprises show. The data collection was made through questionnaire filled by employees, review of policy documents and interview with general managers of both enterprises. The sample respondents for administration of questionnaire were selected on random basis from each work units as groups in each enterprise. These were 32 in the privatized and 68 in the public enterprise which constitute 10% of employees in each. This case study contributes empirical information about performance management and rewards in privatized and public enterprise. Findings show that, in many instances, performance management practices are not significantly different between these enterprises. In some parameters of performance management, the privatized enterprise is found better than the public enterprise. However, this study has limitation in that a case study is not conclusive for all other similar organizations. The study concludes within a set of recommendations for improved practice in all sub sets of performance management and rewards. . Among others, both enterprises are recommended to make their PMS one that contributes for employees' performance. Moreover, improved mentoring, giving autonomy for employees, to use 360 degree feedback appraisal and to consider individual performance while rewarding are the most important points recommended

description: Topological phases are greatly enriched by including non-Hermiticity. While most works focus on the topology of the eigenvalues and eigenstates, how topologically nontrivial non-Hermitian systems behave in dynamics has only drawn limited attention. Here, we consider a breathing honeycomb lattice known to emulate the quantum spin Hall effect and exhibits higher-order corner modes. We find that non-reciprocal intracell couplings introduce gain in one pseudo-spin subspace while loss with the same magnitude in the other. In addition, non-reciprocal intracell couplings can also suppress the spin mixture of the edge modes at the boundaries and delocalize the higher-order corner mode. Our findings deepen the understanding of non-Hermitian topological phases and bring in the spin degree of freedom in manipulating the dynamics in non-Hermitian systems.

description: In high speed metal forming, determination of contact stresses applied to forming dies is necessary in order to identify the requirements to the die material. Contact stresses greatly control the die design due to their effects on die durability. Very high contact stresses and fracture under impulsive loading have been reported in literature on contact type of high speed forming. In pulsed forming operations using electro-hydraulic forming (EHF), a work piece is often accelerated into the die cavity of a desired shape resulting in a substantial impact pressure on the die. Contact algorithm and mesh size play an essential role in providing accurate results in such high speed processes. Using the soft contact model with an appropriate control of the penetration value provided stable and consistent contact stresses.

description: The electromagnetic forming process is high-velocity manufacturing techniques that use electromagnetic forces to shape tube and sheet metal parts. Aluminum alloys are widely used in engineering structures and components where light- weight and corrosion resistance are required. Electromagnetic forming process are successfully employed for the materials that are difficult to form by conventional methods because of spring back, as this process achieves large amount of plastic deformation without spring back. In addition, electromagnetic forming improves mechanical properties of the materials, especially, its hardness, and also increases the rate of production. In this paper, the experimental investigation and analysis on electromagnetic compression forming of aluminum alloy AA6101 tubes is presented. Aluminum alloy tubes of outer diameter 40 mm and wall thickness of 2 mm with a nominal tensile strength of 214 MPa were electromagnetically compressed using a 4 turn helical actuator that discharges energies up to 20 kJ. It is found that a maximum of 15.85% reduction in outer diameter could be achieved during electromagnetic forming at 18 kJ with an approximate discharge current of 160 kA. The post- forming hardness, micro structure and deformed grain size were also studied. The experimental results were correlated with mathematical analysis using MATLAB and also with simulation using ANSYS. The comparison of analytical results with experiment and simulation showed good.

Microphysics in the gamma ray burst central engine

description: We calculate the structure and evolution of a gamma ray burst central engine where an accreting torus has formed around the newly born black hole. We study the general relativistic,MHD models and we self-consistently incorporate the nuclear equation of state. The latter accounts for the degeneracy of relativistic electrons, protons, and neutrons, and is used in the dynamical simulation, instead of a standard polytropic -law. The EOS provides the conditions for the nuclear pressure in the function of density and temperature, which evolve with time according to the conservative MHD scheme. We analyze the structure of the torus and outflowing winds, and compute the neutrino flux emitted through the nuclear reactions balance in the dense and hot matter. We also estimate the rate of transfer of the black hole rotational energy to the bipolar jets. Finally, we elaborate on the nucleosynthesis of heavy elements in the accretion flow and the wind, through computations of the thermonuclear reaction network. We discuss the possible signatures of the radioactive elements decay in the accretion flow. We suggest that further detailed modeling of the accretion flow in GRB engine, together with its microphysics, may be a valuable tool to constrain the black hole mass and spin. It can be complementary to the gravitational wave analysis, if the waves are detected with an electromagnetic counterpart.
