description: A procedure is presented to map from the spatial correlation parameters of a turbulent density field (the radial and binormal correlation lengths and wavenumbers, and the fluctuation amplitude) to correlation parameters that would be measured by a Beam Emission Spectroscopy (BES) diagnostic. The inverse mapping is also derived, which results in resolution criteria for recovering correct correlation parameters, depending on the spatial response of the instrument quantified in terms of Point-Spread Functions (PSFs). Thus, a procedure is presented that allows for a systematic comparison between theoretical predictions and experimental observations. This procedure is illustrated using the MAST BES system and the validity of the underlying assumptions is tested on fluctuating density fields generated by direct numerical simulations using the gyrokinetic code GS2. The measurement of the correlation time, by means of the cross-correlation time-delay (CCTD) method, is also investigated and is shown to be sensitive to the fluctuating radial component of velocity, as well as to small variations in the spatial properties of the PSFs.

Year: 2016

description: Background: Reproductive health care is the constellation of methods, techniques and services that contribute to reproductive health and well-being by preventing and solving sexual health problems. Utilization of those services is an important component in preventing adolescents from different sexual and reproductive health problems. Objective: This study was aimed to investigate the level of reproductive health services utilization and associated factors among adolescents of age 15-19 who live in DebreBirhan town, Amhara National Regional State (ANRS), Ethiopia, 2016. Methodology: A community-based cross-sectional study was employed to assess reproductive health service utilization and its associated factors by administering a pre- tested semi-structured questionnaire from April 5 - May 1, 2016. A multi stage systematic sampling technique was used to select a total of 648 adolescents living in 5 randomly selected kebeles of DebreBirhan town. Data were entered and analyzed by SPSS version 21 software package. Logistic regression was done to identify possible factors associated with reproductive health service utilization. P value less than 0.05 was considered as a level of significance. Results: About one-third (33.8%) of adolescents utilized at least one of reproductive health services. Adolescents who had discussed sexual and reproductive health issues with their sexual partner and peers were 2 times more likely to use RH services than their counter parts (AOR= 2.368, 95% CI: 1.168-4.802 and AOR= 2.360, 95% CI: 1.155-4.820 respectively). Adolescents who weren't co-resided with both their parents were also about 2 times more likely to utilize RH service than those who were living together (AOR= 2.570, 95% CI= 1.155-4.820). Positive perception of oneself towards acquisition of HIV/AIDS urged the adolescents to use RH services twice than those who didn't perceive themselves as risky (AOR= 2.231, 95%CI: 1.001 – 4.975). Conclusion and recommendation: Utilization of RH services among adolescents in the study area were low. Discussion with sexual partner and peers, risk perception of oneself towards the acquisition of HIV/AIDS was among the predictors of RH services usage. Therefore, interventions such as advancing adolescents' knowledge, facilitating parent to child communication, strengthening of youth centers and school reproductive health clubs are important steps to improve adolescent reproductive health service utilization. Key words: Reproductive health, Service utilization, Adolescent (of age 15-19)

description: There is a need among transportation maintenance decision makers for a better understanding of the long-term behavior of railroad tracks. The use of accurate techniques (maintenance model and strategy) to predict track conditions increases track safety and maintenance effectiveness as well as reduce maintenance costs through improve planning. This paper describes the track maintenance model and strategyrelevant for Addis Ababa Light Rail Transit.By using reliability model with weibull distribution, the expected number of critical and degraded failures are determined. Then three failure mechanisms are determined and the rate of critical and degraded failures is determined for each failure mechanism. Finally the governing value of critical and degraded failure are chosen to determine reliability parameters such as mean time to failure(MTTF),mean time to detect(MTTD),mean time before failure(MTBF),mean time to repair(MTTR) and preventive maintenance index(Ipm). The analysis result shows that, the Frequency of critical failure is reduced by 56%by conducting three inspection per year. And also the Mean time until any failure is detected by conducting inspection at every four months of interval for AALRT Railway track line (MTBF) is obtained as 2.55 years. Then after, four maintenance strategies are developed for AALRT. These are: Repair as soon as the component is identified to be in a state where repair is necessary, repair when the component is identified in the state where a major repair is required, repair when the component is identified as being in the state where renewal is needed and no repair, component is allowed to deteriorate without any intervention.

description: Non Born-Oppenheimer quantum dynamics of H$_{2}^{+}$ excited by shaped one-cycle laser pulses linearly polarized along the molecular axis have been studied by the numerical solution of the time-dependent Schrödinger equation within a %three-body three-dimensional model, including the internuclear separation, $R$, and the electron coordinates $z$ and $ρ$. Laser carrier frequencies corresponding to the wavelengths $λ_{l}=25$~nm through $λ_{l}=400$~nm were used and the amplitudes of the pulses were chosen such that the energy of H$_{2}^{+}$ was close to its dissociation threshold at the end of any laser pulse applied. It is shown that there exists a characteristic oscillation frequency $ω_{\rm osc} \simeq 0.2265$~au (corresponding to the period of $τ_{\rm osc} \simeq 0.671$~fs and the wavelength of $λ_{\rm osc} \simeq 200$~nm) that manifests itself as a "carrier" frequency of temporally shaped oscillations of the time-dependent expectation values $\langle z \rangle$ and $\langle \partial V/\partial z \rangle$ that emerge at the ends of the laser pulses and exist on a timescale of at least 50~fs. Time-dependent expectation values $\langle ρ\rangle$ and $\langle \partial V/\partial ρ\rangle$ of the optically-passive degree of freedom, $ρ$, demonstrate post-laser-field oscillations at two basic frequencies $ω^ρ_{1} \approx ω_{\rm osc}$ and $ω^ρ_{2} \approx 2ω_{\rm osc}$. Power spectra associated with the electronic motion show higher- and lower-order harmonics with respect to the driving field.

description: A full understanding of the spacetime evolution of the QCD matter created in a heavy ion collision requires understanding the properties of the initial stages. In the weak coupling picture these are dominated by classical gluon fields, whose properties can also be studied via the scattering of dilute probes off a high energy hadron or nucleus. A particular challenge is understanding small systems, where LHC data is also showing signs of collective behavior. We discuss some recent results of on the initial matter production and thermalization in heavy ion collisions, in particular in the gluon saturation framework.

description: A Raman spectroscopy study was carried out for ZnGeN2 with direction of propagation along the (0001) crystallographic direction on hexagonal single crystal platelets obtained by reaction of gaseous ammonia with a Zn-Ge-Sn liquid alloy at 758 degree C. The sample geometry allowed measurement of the a2 and a1 Raman modes. First-principles calculations were carried out of the spectra. Measurements with crossed polarizers yielded spectra that agreed well with first-principles calculations of the a2 modes. Measurements with parallel polarizers should in principle provide the a1L modes. However, for most of the Raman modes, the LO-TO splitting was calculated to be very small, and for the few modes which were predicted to have larger LO-TO splittings, the LO mode was not observed. This absence is tentatively explained in terms of overdamped LO-plasmon coupling. LO-TO mode crossing was identified by comparing the calculated eigenvectors and intensities of individual modes. Some features in the experimental spectra were identified as arising from critical points in the phonon density of states and are indicative of the degree of disorder on the cation lattice.

Management of Regenerative Braking Energy for Addis Ababa Light Rail Transit System
Creators: name: Mequanint, Biazen
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Addis Ababa light railway is one of the newly constructing railway transport system in Ethiopia. Urban rail plays a key role in the sustainable development of metropolitan areas for several reasons such as its high capacity, energy efficiency and lack of local air pollution. Electricity has become the primary source of traction power in modern railways. DC-electrification is often used for urban public transport. Most electric trains in DC-electrified railways are presently equipped with regenerative braking system. Regenerative braking is a means to save energy and reduce maintenance costs in railway industry. Ultra-capacitor is a major promising alternative of energy storage technologies in the urban rail system. Compared to other storage technology, the ultracapacitor has the advantages of rapid charging and discharging frequencies, a long cycle life and high power density, which highly match the characteristics of urban rail transit such as short running time between stations, frequent accelerating and braking and booming power within a short time. In this thesis a braking energy recovery system based on super-capacitor is presented for Addis Ababa light rail transit system. Regenerative brake is preferably applied as service brake for AART vehicles. Taking the movement of Addis Ababa light rail transit trains between two stations for design purpose, it is shown that 34 percent of consumed energy can be regenerated using regenerative braking system. Regenerated energy is fed back to power other train in the network through brake chopper module or such energy is depleted by brake resistor when there is no train in the network to consume this energy. The thesis assesses design of onboard super capacitor based energy storage system for saving energy which is to be depleted by brake resistor. Based on the design I capacitance of super capacitor is required to save regenerated pick energy. In order to validate the design and do further research, the thesis presents a mathematical model of the whole system. At the end, the simulation is done, the results of simulation has been developed in Matlab programs and Simulink with theoretical analysis.

description: Railway networks are complex technical systems. Investments in railway infrastructure are expensive and already constructed railway infrastructure is not easily adjusted or changed. Dimensioning and constructing railway lines and networks therefore require extensive knowledge of future operation and demand. However, experience shows that the traffic often develops differently than expected. This means that railway infrastructure has to be designed for flexibility, i.e. for different operational conditions. To achieve such flexibility, a deep knowledge of infrastructure, timetable and perturbation properties, as well as inter-correlations between these, is essential. This research has been investigate the impact of various operational changes on different level of heterogeneity to specify the potential use of operational changes to reduce delay in different scenarios especially for single- and double-track systems based on graphical calculation from time-space diagram and CN parametric model. The time-space diagram which is a simple but powerful graphical thinking tool has been used to mode the idealized existing operation. CN parametric model was used to investigate the impact of various operational changes on differing levels of heterogeneity on a hypothetical signalized, single-track rail line using delay as capacity metric unit. Changes considered included: adding sidings, increase in train headway, equalizing maximum speeds, increasing uniformity, removing dispatching priorities and the combination of the best ones. Since the railway transportation can have significant effects on mobility, economic development, environmental quality, government finance and the quality of life, this study did analyze that the change of each parameters would have great improvement for the idealized existing operation, the combination of specified alternatives, specially adding sidings did provide a great capacity increment for the particular subdivisions. Those results from this study has great significance for railway operational capacity problems specifically for single -track lines and provides insight into which aspects of train type heterogeneity have the greatest impact on delay and leads to investigate the potential use of different operational changes that may reduce this delay in Ethiopian, Addis Ababa-Djibouti rail line.

description: Wheel and rail is one of the most important material used to support and guide rail vehicle safely and smoothly. Since wheel and rail suffers from various interacting mechanical and thermal forces, friction modifiers, various contaminants and environmental atmosphere, wear poses large Problem on wheel and rail. Wheel and rail wear can be result in an extensive cost for truck owner, if it is not predicated and prevented in an efficient way. To limit these costs, one measure is to predicate and prevent wheel and rail wear through wear modeling. The purpose of this research is to investigate the wear analysis on wheel / rail in rolling and sliding contact using CATIA V5 R16 software and ANSYS 16.0 Workbench. The wear of the wheels has been studies on stress structure as result and the analysis is done for two wheels having different material composition (that is Bainitic steel which is new material and R7 which is using by Ethiopian Light Railway Transit AALRT) Using stress output as input for structural analysis different stress concentration are observed The result obtained for the two wheels shows that wheel two has excellent hardness, strength and have good resistance wear Therefore, Bainitic steel can be applied to wheels in railway system

description: Higher education administrators today are simultaneously encountering first-year college students that are struggling to handle common challenges and parents intervening on behalf of their college children. With the ongoing emerging adult mental and emotional health crisis, parental involvement continues to be on the rise. The occurrences of the two phenomena- the current emotional health crisis and high parental involvement- provokes the question of if and how they might be related. Drawing from coping theory and parental attachment theory, this study employed a quantitative survey design to analyze the coping skills and parental attachment levels of a first-year student sample at a large, public research institution in the Northeast United States. A series of T-tests, ANOVAs, and MANOVAs were conducted to determine differences in both coping skill and parental attachment theory by gender identity, race/ethnicity, and first-generation status. A regression analysis was conducted to determine if parental attachment did affect the coping skill level of first-year students. Results showed differences in parental attachment and coping ability across different first-year populations, and that the parental attachment level of a first-year student accounted for 13.1% of the variation in coping skill level. Implications include formal emotional health education in college, meaningful parent programming, strict interpretation of FERPA, and general practice of encouraging parents to allow students to problem-solve on their own.

description: We present a scenario where a $Z_2$-symmetric scalar field $ϕ$ first drives cosmic inflation, then reheats the Universe but remains out-of-equilibrium itself, and finally comprises the observed dark matter abundance, produced by particle decays à la freeze-in mechanism. We work model-independently without specifying the interactions of the scalar field besides its self-interaction coupling, $λϕ^4$, non-minimal coupling to gravity, $ξϕ^2R$, and coupling to another scalar field, $gϕ^2σ^2$. We find the scalar field $ϕ$ serves both as the inflaton and a dark matter candidate if $10^{-9}\lesssim λ\lesssim g\lesssim 10^{-7}$ and $3 \rm{keV} \lesssim m_{\rm ϕ}\lesssim 85 \rm{MeV}$ for $ξ=\mathcal{O}(1)$. Such a small value of the non-minimal coupling is also found to be of the right magnitude to produce the observed curvature perturbation amplitude within the scenario. We also discuss how the model may be distinguished from other inflationary models of the same type by the next generation CMB satellites.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Now a day the railway transport infrastructure in Ethiopia is the major issues in relation to the development of the country. To strengthen this infrastructure, related researches must be conducted at the beginning of the construction of the sector. This paper which mainly concerned about the analysis of crack propagation of rail due to vertical wheel load is done to predict the initiated crack growth rate under different load conditions. The objective of this research is to analyze propagation of initiated crack and determine its growth rate under different load conditions and to identify the maximum axle load used, which is basic to justify the way of crack propagation near to the contacting interface. A design axle load of 25ton (ERC) and 22.5tons and 20tons are assumed for the calculation of Stress Intensity factors. A wheel of S1002 profile and a UIC60 rail profile are modeled using CatiaV5R19 software. The models are assembled and imported to Ansys 15.0 release workbench and then to Ansys APDL to simulate wheel/rail contact. The material properties of rail steel are taken and a side crack model is made to simulate crack propagation of railroad rail taking only the vertical load from wheel. The cracked plate is assumed as it is taken from a cracked rail. Then, initiated cracks of different sizes are taken and tensile stress loads are applied on each crack length. The analysis is done taking into account the theories of Linear Elastic Fracture Mechanics. The analysis is based on numerical and analytical methods. For numerical methods, the analytical stress intensity factor KI is calculated using a formula given by (Ewalds and Wanhill, 1989). The analytical method uses Ansys KCALC (Displacement extrapolation method) based on the stress and strain plane conditions. Both results are compared with the numerical results. The tensile loads which take in to account the effects of the dynamic magnification of the vertical wheel load show higher SIF and the life cycle the cracks under these cases are shorter.

description: The disc brake is a device for slowing or stopping the rotation of a wheel. Braking of the vehicle leads to heat generation during each braking event. Transient thermal analysis of the Rotor Disc of Disk Brake is aimed at evaluating the performance of ventilated disc brake rotor of a rail vehicle under emergency braking conditions and there by assist in optimization the curves of the shape of ventilated disc to identified the thermal analysis effect during braking. Here Disc brake modeled with CATIA software and its analysis is done using ANSYS workbench 12 with considering CFD-cfx package software. The main purpose of this study is to analyzing the thermal behavior of the ventilated disc brake during the braking phase by optimization the shapes of the curves of the vented disc and compare results. The coupled thermal-structural analysis is used to determine the Von Mises stress established in the disc for ventilated disc with the same materials and other data from ERC to enhance performance of the rotor disc. The results from the simulation with changing shapes of the vane like vane number, vane angle and vane curve radius; as vane number 50 ,60, 70 and 80 , then temperature generated reduced from 311.76-302.67[°C] until vane number 70. But at vane number 80 it is 308.94 [°C].And with changing the straight vane number 50 to 5, 10 and 20 angles its values of temperature generating at a time of 5.2488 [s] is 302.9, 239.86 and 302.24 respectively and at vane numbers 60 and 70 at angle 5 and 20 their values are 310.44, 310.19[°C] at time 5.2488 [s] and 309.86, 309.72 [°C] at time 5.0868 [s]respectively. At changes of vane curve radius from straight to 120 to 60mm its generating temperature is reduced 312.03 to 309.83 [°C] at time 5.2488[s]. Generally from simulation of emergency brake at braking time 9.72[s], reduced generating temperature at vane number 70 and at vane angle 5 with vane number 50 are 302.67 and 302.9[°C] respectively which preferable at emergency brake-1, when simulated at tentative with applying initial temperature induced at emergency brake-1, induced temperature at emergency brake-2 increase to 361.99 and 362.55[°C], these are preferable to compare from the current AALRT uses which is induced 383.26[°C] at emergency brake-2.

description: The two parameters Weibull function is used to describe the charged particle multiplicity distribution in $e^{+}e^{-}$ collisions at the highest available energy measured by TASSO and ALEPH experiments. The Weibull distribution has wide applications in naturally evolving processes based on fragmentation and sequential branching. The Weibull model describes the multiplicity distribution very well, as particle production processes involve QCD parton fragmentation. The effective energy model of particle production was verified using Weibull parameters and the same was used to predict the multiplicity distribution in $e^{+}e^{-}$ collisions at future collider energies.

description: Low-energy collective electronic excitations exhibiting sound-like linear dispersion have been intensively studied both experimentally and theoretically for a long time. However, coherent acoustic plasmon modes appearing in time-domain measurements are rarely observed due to Landau damping by the single-particle continua. Here we report on the observation of coherent acoustic Dirac plasmon (CADP) modes excited in indirectly (electrostatically) opposite-surface coupled films of the topological insulator Bi2Se3. Using transient second harmonic generation, a technique capable of independently monitoring the in-plane and out-of-plane electron dynamics in the films, the GHz-range oscillations were observed without corresponding oscillations in the transient reflectivity. These oscillations were assigned to the transverse magnetic and transverse electric guided CADP modes induced by the evanescent guided Lamb acoustic waves and remained Landau undamped due to fermion tunneling between the opposite-surface Dirac states.
Recent hadronic resonance measurements at ALICE

description: In heavy-ion physics, measurements of short-lived hadronic resonances allow the properties of the hadronic phase of the collision to be studied. In addition, resonances can be used along with stable hadrons to study parton energy loss in the quark-gluon plasma and the mechanisms that shape hadron pT spectra at intermediate transverse momenta. Resonance measurements in small systems serve as a reference for heavy-ion collisions and contribute to searches for collective effects. An overview of recent results on hadronic resonance production measured in ALICE is presented. These results include the pT spectra and yields of the rho(770)0, K*(892)0, and phi(1020) mesons in pp, p-Pb, and Pb-Pb collisions at different energies as well as the Sigma(1385)+/- and Xi(1530)0 baryons in pp and p-Pb collisions.

description: We report on the first fully differential calculation for double Higgs boson production through gluon fusion in hadron collisions up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. The calculation is performed in the heavy-top limit of the Standard Model, and in the phenomenological results we focus on pp collisions at 14 TeV. We present differential distributions through NNLO for various observables including the transverse-momentum and rapidity distributions of the two Higgs bosons. NNLO corrections are at the level of 10%-25% with respect to the next-to-leading order (NLO) prediction with a residual scale uncertainty of 5%-15% and an overall mild phase-space dependence. Only at NNLO the perturbative expansion starts to converge yielding overlapping scale uncertainty bands between NNLO and NLO in most of the phase-space. The calculation includes NLO predictions for pp -> HH+jet+X. Corrections to the corresponding distributions exceed 50% with a residual scale dependence of 20%-30%.

Exchange Rate Pass-Through to Import and Consumer Prices: Evidence from Ethiopia
Creators: name: Berga, Helen
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: The fact that Ethiopia adopted managed floating exchange rate policy since 1992 as well as various trade reform measures taken makes the country's import and consumer prices susceptible to the effects of exchange rate movements. Thus, the study investigates the degree of ERPT and its asymmetry to import and consumer prices in Ethiopia between 1991/92 and 2010/11 using two types of VAR models (SVAR and CVAR). Based on SVAR analysis the paper found that ERPT in Ethiopia during the period under review is moderate, significant and persistent in the case of import price and low and short lived in the case of consumer prices. The cointegration analysis shows incomplete ERPT to import price and absence of pass-through to consumer price in the long run. The result obtained from the asymmetric model suggests that ERPT to import prices is higher in periods of Birr depreciation than appreciation. Also, pass-through to import prices is found to be higher in periods of small changes than large changes in the exchange rate. The study also tries to get pass-through estimates in different inflation environments in order to test Taylor's hypothesis. However, no evidence is found which supports the hypothesis in the case of Ethiopia. The fact that ERPT was found to be incomplete has useful implication to policymakers, especially in the design and implementation of exchange rate and monetary policy.

description: Medication non-adherence is a significant challenge in healthcare, leading to poor health outcomesand increased healthcare costs. This paper proposes a novel patient engagement platform that leveragesmachine learning algorithms and web technologies to improve medication adherence. The platform utilizespredictive modeling to identify patients at risk of non-adherence, personalized interventions through web andmobile interfaces, and real-time monitoring to support patients in their medication regimens. By combiningthese technologies, we aim to create a more effective and scalable solution to the persistent problem ofmedication non-adherence.

description: Vibrational-excitation cross sections of ground electronic state of carbon dioxide molecule by electron-impact through the CO2-(2Π) shape resonance is considered in the separation of the normal modes approximation. Resonance curves and widths are computed for each vibrational mode. The calculations assume decoupling between normal modes and employ the local complex potential model for the treatment of the nuclear dynamics, usually adopted for the electron-scattering involving diatomic molecules. Results are presented for excitation up to 10 vibrational levels in each mode and comparison with data present in the literature is discussed.

description: Dual-comb spectroscopy is a powerful technique for real-time, broadband optical sampling of molecular spectra which requires no moving components. Recent developments with microresonator-based platforms have enabled frequency combs at the chip scale. However, the need to precisely match the resonance wavelengths of distinct high-quality-factor microcavities has hindered the development of an on-chip dual comb source. Here, we report the first simultaneous generation of two microresonator combs on the same chip from a single laser. The combs span a broad bandwidth of 51 THz around a wavelength of 1.56 $μ$m. We demonstrate low-noise operation of both frequency combs by deterministically tuning into soliton mode-locked states using integrated microheaters, resulting in narrow ($
