Fatigue Durability Analysis for Welded Bogie Frame of AALRT
Creators: name: Ruhama, Minwuyelet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This research paper presents the fatigue durability analysis for the welded bogie frame of AALRT. The purpose of this research is to observe the fatigue life of the welded bogie frame and to protect it from failure. In the analysis of the research a three-dimensional finite element model of the bogie frame has been used to investigate the effect of the applied loading force at the frame surface area and observing the effects on the welded joints. The specimen S/N-curve is locally modified by different influence parameters as stress-gradient to take into account notch effects, mean-stress influence which is quantified by means of a Haigh-diagram, surface roughness and treatments, temperature, technological size, etc. This paper discusses some applications of the outstanding fatigue simulation program FEMFAT supporting the assessment of the applied loads and welding seams. On the bases of the model analysis the following results have been achieved. Output results without Sensitivity Factor: – maximum and minimum log10 damage values are 30 and -7.09 respectively, maximum and minimum log10 endurance safety factors are 1 and -5.11 respectively, maximum and minimum fatigue limits are 282 N/mm2 and 255 N/mm2 respectively, and fatigue life is 2e^6. Output results with small weld seam sensitivity Factor: – maximum and minimum log10 damage values are 30 and -20 respectively, maximum and minimum log10 endurance safety factors are 1 and -5.11 respectively, maximum and minimum fatigue limits are 282 N/mm2 and 0 N/mm2 respectively, and fatigue life is 2e^6. Hence it is possible to conclude that the maximum damage result, which is 30 in number is much exaggerated result, it is because the weld quality that I have taken is poor. Whereas the fatigue limit at each analytical outputs has been proved to be the recommended value. The endurance safety factor is below the anticipated value. There for a special attention should be given to the welded joints. Based on sensitivity seam thickness results, it is possible to conclude that welded connections are almost nearer to failure because they are highly exposed to residual stress. The study is significant and applicable because it introduces new knowledge on fatigue life analysis of welded bogie frame in the minds of the beneficiaries of the study particularly to those who are working in Railway Corporation.

description: Very massive stars in the final phases of their lives often show unpredictable outbursts that can mimic supernovae, so-called, "SN impostors", but the distinction is not always straigthforward. Here we present observations of a luminous blue variable (LBV) in NGC 2770 in outburst over more than 20 years that experienced a possible terminal explosion as type IIn SN in 2015, named SN 2015bh. This possible SN or "main event" was preceded by a precursor peaking $\sim$ 40 days before maximum. The total energy release of the main event is $\sim$1.8$\times$10$^{49}$ erg, which can be modeled by a $

Formation of Tidal Captures and Gravitational Wave Inspirals in Binary-Single Interactions

Year: 2016
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We perform the first systematic study on how dynamical stellar tides and general relativistic (GR) effects affect the dynamics and outcomes of binary-single interactions. For this, we have constructed an N-body code that includes tides in the affine approximation, where stars are modeled as self-similar ellipsoidal polytropes, and GR corrections using the commonly-used post-Newtonian formalism. Using this numerical formalism, we are able resolve the leading effect from tides and GR across several orders of magnitude in both stellar radius and initial target binary separation. We find that the main effect from tides is the formation of two-body tidal captures that form during the chaotic and resonant evolution of the triple system. The two stars undergoing the capture spiral in and merge. The inclusion of tides can thus lead to an increase on the stellar coalescence rate. We also develop an analytical framework for calculating the cross section of tidal inspirals between any pair of objects with similar mass. From our analytical and numerical estimates we find that the rate of tidal inspirals relative to collisions increases as the initial semi-major axis of the target binary increases and the radius of the interacting tidal objects decreases. The largest effect is therefore found for triple systems hosting white dwarfs and neutron stars. In this case, we find the rate of highly eccentric white dwarf - neutron star mergers to likely be dominated by tidal inspirals. While tidal inspirals occur rarely, we note that they can give rise to a plethora of thermonuclear transients such as Ca-rich transients.

Year: 2014

description: Nowadays, 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 dynamic strategic planning for rail project design is done to predict and minimize failures caused by improper strategic planning. In most cases, financial performance of railways deviates a lot from the forecasts. Means that, costs exceed predictions by far and demand is less than what is forecasted. The logic behind this is that the financial performance of the system can be improved if there is a pre specified plan for every possible future scenario. The entire analysis is done for Ethiopian railway projects deeply for first phase projects. The objective of this thesis is having a flexible plan for building and operating railway projects and to determine the optimum planning. The method to be used is based on data collecting through actual visit of construction site/area of concern and consult individuals for further clarification and confirmation. Additionally interviews with selected key stakeholders involved into ports and corridors management of railway operations area. Benefits of these options will be realized by arrival of new information as time goes by. This flexibility can increase long term benefits and minimizing the possibility of disastrous losses. The final outcome of this study, based upon NPV and decision tree planning software is to construct two routes and the construction of additional routes will be determined depending on the demand; i.e. adding three more routes if the demand is high and keeping the existing routes if the demand is either medium or low. The results obtained were found to be realistic and useful for the planning of Ethiopian rail routes. Applications and an analysis of the Ethiopian rail project situation can help and improve the financial performance of the current rail route.

description: We study the orbital diamagnetic susceptibility in excitonic condensation phase using the meanfield approximation for a two-band model defined on a square lattice. We find that, in semiconductors, the excitonic condensation acquires a finite diamagnetic susceptibility due to spontaneous hybridization between the valence and the conduction bands, whereas in semimetals, the diamagnetic susceptibility in the normal phase is suppressed by the excitonic condensation. We also study the orbital diamagnetic and Pauli paramagnetic susceptibilities of Ta2NiSe5 using a two-dimensional three-band model and find that the calculated temperature dependence of the magnetic susceptibility is in qualitative agreement with experiment.

Identification of the Best Material Combination Between Wheel and Rail of Railway Vehicle with Minimum Wear Rate
Creators: name: Natnael, Tesfamichael
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Wear is a natural phenomenon that exists when two bodies, which are in contact, perform a relative motion; this is also true for the wheel and rail of a railway vehicle. This wear is mainly dependent on the type of material they are made of. There is a tolerable level of wear that is safe to the railway operation. Once this critical wear level is reached, it is mandatory to re-profile the wheel, grind the rail. However, after some time it will be worn out to the level it can no more be used and the whole system must be replaced with a new one. This indicates that there is a need to focus on the wear properties of wheel and rail materials in order to secure a safe and sustainable railway operation. This research tries to set new combinations (pairs) of wheel and rail materials, simulate them for wear performance using a multi body simulation software (SIMPACK). An important criteria for the comparison is the hardness and strength of the wheel/rail materials. Then compare the wear rate of the different combination and identify for the best material combination with the minimum wear rate. Based on the simulation it is found that a softer wheel material rolling on a relatively harder rail material has a minimum wear rate. But increasing the hardness of both wheel and rails will not secure better wear performance. Safety is also considered in this research using the derailment coefficient parameter. Based on the minimum derailment coefficient value among the combinations those with better wear performance showed a better safety.
A Detailed Study of factors That Enhances the Performance of High-rate Li-Air Batteries
Creators: name: Zhang, Chengji
Publisher: name: University of Illinois at Chicago
Year: 2023

description: The rise in demand for electric transportation is widely acknowledged as a way to decrease reliance on fossil fuels and mitigate the impact of climate change. Among various contenders for advanced energy storage technology, the lithium-air battery has garnered significant attention due to its high theoretical energy density that is comparable to gasoline combustion. This renders it a promising option for powering fully electric vehicles. However, one of the significant challenges in its development is the high overpotential that occurs during the redox reaction between charge and discharge. Additionally, battery cycling results in electrolyte and electrode decomposition, which leads to cathode blockage, thereby reducing energy efficiency and cycle life. To overcome these challenges, this study introduces various methods, including a new solid-state catalyst and bi-functional electrolyte additives. As a result of these efforts, a significantly improved Li-O2 cell was developed, with a current density of up to 1mA/cm2 (equivalent to 10000mA/g). Furthermore, a Li-Air battery system was reported, and its discharge products were found to be lithium superoxide, as intended, rather than lithium peroxide under high current densities, thereby reducing discharge overpotentials and preventing cathode clogging. Additionally, 20 different RMs were analyzed for their electrochemical properties in the Li-O2 system using DMSO and TEGDME electrolytes through cyclic voltammetry (CV) experiments. The redox potential, cathodic and anodic peak separation, and current intensities were among the measured features. Different characterization techniques, including SEM, TEM, and Raman, were employed to investigate the battery's morphology and redox products, and battery cycling tests were conducted to gain a better understanding of the two-step mechanism of the Li-Oxygen battery system.

description: Generative AI systems, such as ChatGPT, have recently made their way into everyday life, setting off an alarm as to who uses them and how. Human computation via crowdsourcing has traditionally focused on problems requiring a ``human touch," problems that machines cannot (yet) solve. This work explores how Generative AI affects the present and future of crowdwork. We have conducted a large-scale, light-weight survey of crowdworkers' activities and beliefs on three popular platforms (Amazon Mechanical Turk, Prolific and Clickworker), asking 1.400 crowdworkers located across three different continents for their input. Our results not only explore the use of Generative AI tools by crowdworkers in the completion of the task, but also, document the emergence of a new type of crowdsourcing task. Additionally, we found strong evidence that the attitude of crowdworkers towards Generative AI is associated with the platform in which they operate.

description: We demonstrate that the quantum mutual information (QMI) is a useful probe to study many-body localization (MBL). First, we focus on the detection of a metal--insulator transition for two different models, the noninteracting Aubry-André-Harper model and the spinless fermionic disordered Hubbard chain. We find that the QMI in the localized phase decays exponentially with the distance between the regions traced out, allowing us to define a correlation length, which converges to the localization length in the case of one particle. Second, we show how the QMI can be used as a dynamical indicator to distinguish an Anderson insulator phase from an MBL phase. By studying the spread of the QMI after a global quench from a random product state, we show that the QMI does not spread in the Anderson insulator phase but grows logarithmically in time in the MBL phase.

Adaptation of Station Design Parameters for Addis Ababa Light Railway in Ethiopian Context
Creators: name: Kaleab, Tesfaye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Station is a basic production unit of railway transportation, integrating technical equipment relating to transportation. For the last couple of years investigations have been conducted in Ethiopia in railway site selection. One of that is the Addis Ababa light railway, where two alternative rights of way are seen. That is north- south corridor and East –west corridor of Addis Ababa which is about 34km. An important subject in the planning of a new railway line is the design of the railway stations since they affect the capacity, flexibility and the safety of the rail transport system. The main objective of paper is to investigate how stations can be designed to align with the proposed high speed railway concepts on the line of the light railway based the topography, demography, climatic and economic conditions of the country. The focus in the report is to adapt parameters of station design and investigate how they are affected by the high speed railway concepts. This paper consists of a literature study similar to the subject. The knowledge gained is then used to suggest possible station platforms, station safety. Some aspects of station design that are investigated in the literature study are platforms, platform safety issues, necessary dimensions of platforms and stations. It is concluded that the spacing of station and dimension of station (base width and length, plate form of station) is optimized in consideration of satisfying all passengers and the optimization analysis is need in estimation of cost of station. Therefore, sizing station is critical and designers should err on the side of safety when determining the size of the station.

description: In the presence of strong magnetic fields the electronic bandstructure of graphene drastically changes. The Dirac cone collapses into discrete non-equidistant Landau levels, which can be externally tuned by changing the magnetic field. In contrast to conventional materials, specific Landau levels are selectively addressable using circularly polarized light. Exploiting these unique properties, we propose the design of a tunable laser operating in the technologically promising terahertz spectral range. To uncover the many-particle physics behind the emission of light, we perform a fully quantum mechanical investigation of the non-equilibrium dynamics of electrons, phonons, and photons in optically pumped Landau-quantized graphene embedded into an optical cavity. The gained microscopic insights allow us to predict optimal experimental conditions to realize a technologically promising terahertz laser.

description: We present direct estimates of the mean sky brightness temperature in observing bands around 99GHz and 242GHz due to line emission from distant galaxies. These values are calculated from the summed line emission observed in a blind, deep survey for specrtal line emission from high redshift galaxies using ALMA (the 'ASPECS' survey). In the 99 GHz band, the mean brightness will be dominated by rotational transitions of CO from intermediate and high redshift galaxies. In the 242GHz band, the emission could be a combination of higher order CO lines, and possibly [CII] 158$μ$m line emission from very high redshift galaxies ($z \sim 6$ to 7). The mean line surface brightness is a quantity that is relevant to measurements of spectral distortions of the cosmic microwave background, and as a potential tool for studying large-scale structures in the early Universe using intensity mapping. While the cosmic volume and the number of detections are admittedly small, this pilot survey provides a direct measure of the mean line surface brightness, independent of conversion factors, excitation, or other galaxy formation model assumptions. The mean surface brightness in the 99GHZ band is: $T_B = 0.94\pm 0.09$ $μ$K. In the 242GHz band, the mean brightness is: $T_B = 0.55\pm 0.033$ $μ$K. These should be interpreted as lower limits on the average sky signal, since we only include lines detected individually in the blind survey, while in a low resolution intensity mapping experiment, there will also be the summed contribution from lower luminosity galaxies that cannot be detected individually in the current blind survey.

description: A major obstacle to attain the fundamental precision limit of the phase estimation in an interferometry is the identification and implementation of the optimal measurement. Here we demonstrate that this can be accomplished by the use of three conventional measurements among interferometers with Bayesian estimation techniques. Conditions that hold for the precision limit to be attained with these measurements are obtained by explicitly calculating the Fisher information. Remarkably, these conditions are naturally satisfied in most interferometric experiments. We apply our results to an experiment of atomic spectroscopy and examine robustness of phase sensitivity for the two-axis counter-twisted state suffering from detection noise.

description: With 91 months of the publicly available Fermi-LAT Pass 8 data, we analyze the gamma-ray emission from the Milky Way satellites to search for potential line signals due to the annihilation of dark matter particles into double photons. The searched targets include a sample of dwarf spheroidal galaxies, the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). No significant line emission has been found neither in the stacked dwarf galaxy sample nor in the direction of LMC/SMC. The corresponding upper limits on the cross section of DM annihilation into two photons are derived. Compared with results of previous gamma-ray line searches with the Pass 7 data, the current constraints on the line emission from dwarf spheroidal galaxies has been significantly improved in a wide energy range. With the rapid increase of the sample of dwarf spheroidal galaxies (candidates), we expect that the sensitivity of gamma ray line searches will be significantly improved in the near future.

The compactness of the waveguides results in efficient second-order nonlinear devices. A nonlinear conversion of 8% is obtained with a pulsed input in 4 mm long waveguides. The choice of silicon substrate makes the platform potentially compatible with silicon photonics, and therefore may pave the path towards on-chip nonlinear and quantum-optic applications.

description: The study was aimed at design and development of an energy efficient hybrid solar dryer suitable for drying of organic Conilon coffee placed in the town of Seropédica, Rio de Janeiro, Brazil. The energy efficiency and the drying efficiency were the evaluation criteria for thermal performance of the hybrid solar dryer during the coffee drying. Temperature and relative humidity (RH) of the drying and ambient air, solar radiation intensity and coffee weight loss were monitored during the drying process. The process occurred over six consecutive days; the drying time was from 07:00 to 17:00 h, totalling 120 h of operation with an intermittent period (at night) of 14 h. During intermittence, the exhaust system kept off and solar collector and drying chamber sealed. The effective drying period took 60 h, with temperature and RH, respectively, of 38.3 °C and 60.6% outlet of the solar collector, 32.7 °C and 72.2% outlet drying chamber and 27.8 °C and 74.5% ambient air. The maximum temperature in the solar collector and drying chamber reached 54 and 47.7 °C, respectively, with an ambient air temperature of 32 °C at 12:00 h. These values showing temperature increase 22.2 °C in solar collector and 10 ºC drying chamber. The mean variation for the reduction in RH between the drying air inside the solar collector and the ambient air was 28%, while in the chamber obtained in a range of 10.5% at 13:00 h. The solar collector and dryer chamber efficiency were 29.1 and 40.8%, respectively, while the overall dryer efficiency 39.7%.
Development of a Tongue Capability Model for Quantifying Pathology-Related Motor Deficits
Creators: name: Coda, Kyle R
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Motor speech disorders are difficult to evaluate clinically. Current clinical assessment tools are limited to measures of phonetic production rates and do not represent a comprehensive description of the motor capability of the affected muscle groups. Studies on upper limb impairments among stroke survivors have shown that motor free-exploration tasks provide a fuller description of individual motor deficits. To assess tongue motor function, we first developed a novel solution for intra-oral device fixation. Then we analyzed the tongue movement distributions of healthy individuals during a free exploration task in the presence of visual feedback to create a statistical model of healthy tongue capability. Finally, we utilize the healthy model to evaluate the motor deficits of individuals with motor speech disorders. Our preliminary findings are an encouraging step towards the assessment and rehabilitation of motor speech disorders.

To overcome the experimental difficulty that a $p$-wave pairing interaction to form $p$-wave Cooper pairs damages the system before the condensation growth, we first prepare a $p$-wave pair amplitude ($Φ_{p}$) in a spin-orbit coupled $s$-wave superfluid Fermi gas, without any $p$-wave interaction. Then, by suddenly changing the $s$-wave interaction with a $p$-wave one ($U_{p}$) by using a Feshbach resonance, we reach the $p$-wave superfluid phase with the $p$-wave order parameter being symbolically written as $Δ_{p}\sim U_{p}Φ_{p}$. In this letter, we assess this scenario within the framework of a time-dependent Bogoliubov-de Gennes theory. Our results would contribute to the study toward the realization of unconventional pairing states in an ultracold Fermi gas.

description: With the immense number of videos being uploaded to the video sharing sites, issue of copyright infringement arises with uploading of illicit copies or transformed versions of original video. Thus safeguarding copyright of digital media has become matter of concern. To address this concern, it is obliged to have a video copy detection system which is sufficiently robust to detect these transformed videos with ability to pinpoint location of copied segments. This paper outlines recent advancement in content based video copy detection, mainly focusing on different visual features employed by video copy detection systems. Finally we evaluate performance of existing video copy detection systems.

description: We leverage multi-omics approaches RNA-seq and 16S rRNA gene sequencing to characterize non-coding RNAs and microbial community changes in diseases that affect the lungs. In particular, we assess the roles of exosomal microRNAs in rhinovirus (RV)-induced asthma and the lung microbiome alterations in prophylaxis-treated infants with cystic fibrosis. Asthma symptoms are often exacerbated by the common-cold-causing RV. We characterized the temporal behavior of circulating exosomal microRNAs (ExoMiRNAs) in a longitudinal bi-phasic case-control study of mild asthmatic patients (n = 12) and matched non-atopic healthy controls (n = 12) inoculated with rhinovirus. We aimed to define clinical and immunologic characteristics associated with differentially expressed (DE) miRNAs. In total, 26 DE ExoMiRNAs, including (hsa-)let-7f-5p, let-7a-5p, miR-122-5p, miR-101-3p, and miR-126-3p, were identified between asthmatic and healthy subjects after inoculation with RV. Time series clustering identified a unique cluster of upregulated DE ExoMiRNAs with augmented mean expression and a distinct cluster of downregulated DE ExoMiRNAs with decreased mean expression in asthmatic subjects upon RV challenge. Notably, the Upregulated Cluster correlated with Th1 and interferon-induced cytokines/chemokines (IFN-γ and IFN-γ-inducible protein-10) and interleukin-10 (IL-10). Conversely, the Downregulated Cluster correlated with IL-13, a Th2 cytokine, pulmonary function measurements (FVC%, FEV1%, and PEF%), and inflammatory biomarkers (FeNO, eosinophil%, and neutrophil%). Key ExoMiRNA-target genes and anti-viral defense mechanisms of the Upregulated and Downregulated Clusters were identified by network and gene enrichment analyses. Our findings provide insight into the regulatory role of ExoMiRNAs in RV-induced asthma. Cystic fibrosis (CF) is a genetic disorder caused by the mutation of the CFTR gene. Antibiotic prophylaxis treatment has been recommended in certain countries, yet its effect on the lung microbiome and pulmonary function is not clear. In our multi-center observational study of 45 infants at two visits (∼3 and 14 months of age), we found a pulmonary microbial community shift in the prophylaxis-treated infants with CF. Other than the traditional CF bacteria Staphylocuccus and Pseudomonas, non-traditional CF bacteria such as Streptococcus, Neisseria and Gemella were among the core taxa. The prophylaxis-treated infants had a much lower alpha diversity and a higher composition of Streptococcus at the earlier visit, and the higher level of Streptococcus was associated with declined FEV0.5%. We also show that the alteration of the lung microbiota at the early CF may be linked to antimicrobial resistance. Our results suggest that prophylactic treatment may exert an adverse effect on pulmonary function and should be used with caution.

description: In this paper, we discuss the behavior of the Carroll-Field-Jackiw (CFJ) coefficient $k^μ$ arising due to integration over massive fermions, and the modification suffered by its topological structure in the finite temperature case. Our study is based on the imaginary time formalism and summation over the Matsubara frequencies. We demonstrate that the self-energy of photon is non-analytic for the small $k^μ$ limit, i.e., the static limit $(k_0=0,\vec k\rightarrow 0)$ and the long wavelength limit $(k_0\rightarrow 0,\vec k= 0)$ do not commute, while the tensorial structure of the CFJ term holds in both limits.

description: Microstructure emission, involving short time scale, often quasi-periodic, intensity fluctuations in subpulse emission, is well known in normal period pulsars. In this letter, we present the first detections of quasi-periodic microstructure emission from millisecond pulsars (MSPs), from Giant Metrewave Radio Telescope (GMRT) observations of two MSPs at 325 and 610 MHz. Similar to the characteristics of microstructure observed in normal period pulsars, we find that these features are often highly polarized, and exhibit quasi-periodic behavior on top of broader subpulse emission, with periods of the order of a few $μ$s. By measuring their widths and periodicities from single pulse intensity profiles and their autocorrelation functions, we extend the microstructure timescale - rotation period relationship by more than an order of magnitude down to rotation periods $\sim$ 5 ms, and find it to be consistent with the relationship derived earlier for normal pulsars. The similarity of behavior is remarkable, given the significantly different physical properties of MSPs and normal period pulsars, and rules out several previous speculations about the possible different characteristics of microstructure in MSP radio emission. We discuss the possible reasons for the non-detection of these features in previous high time resolution MSP studies along with the physical implications of our results, both in terms of a geometric beam sweeping model and temporal modulation model for micropulse production.

description: We describe the program HERWIRI2.1, which implements order alpha-squared photonic radiative corrections exponentiated at the amplitude level (initial state, final state, and initial-final interference) and electroweak corrections to the matrix element by generating events using the KK Monte Carlo to generate the hard process, with quark initial states generated according to PDFs via an LHAPDF interface. The events can be showered internally using HERWIG6.5 or exported and showered using any desired external showering program. Some early results are shown, including comparisons to HERWIG6.5 and HORACE 3.1.
