description: Using a femtosecond laser writing technique, we fabricate and characterise three-waveguide digital adiabatic passage devices, with the central waveguide digitised into five discrete waveguidelets. Strongly asymmetric behaviour was observed, devices operated with high fidelity in the counter-intuitive scheme while strongly suppressing transmission in the intuitive. The low differential loss of the digital adiabatic passage designs potentially offers additional functionality for adiabatic passage based devices. These devices operate with a high contrast ($>\!90\%$) over a 60nm bandwidth, centered at $\sim 823$nm.
Towards an automatic method for clustering volatile organic compounds in breath samples

Subjects: subject: 89999 Information and Computing Sciences not elsewhere classified
subject: FOS: Computer and information sciences

description: It has been known for some time that vapours and odours produced by the body and breath can have some diagnostic value. This knowledge has been confirmed in recent history within clinical trial studies where animals have been successfully trained to detect diseases, through the sniffing of precise volatile organic profiles. Such metabolites can also be captured using analytical technologies. The term 'breathomics' is used to denote the science of analysing all the metabolites that are found in an organism’s breath. Studies in non-targeted metabolites with breathomics make use of Gas Chromatography-Mass Spectrometry (GC-MS) as the most advisable analytical method. Generally, the metabolic profiling of breath analysis encompasses the handling, configuration, scaling and bundling of thou-sands of features obtained from the GC-MS data obtained from hundreds of participating individuals. Also, as is the case with other technologies used in diagnosis,there are many random and systematic noises that influence breathomics. It is for this reason that multi-step data processing (deconvoluted) is needed. However,this is a process that is not only complex; it is also time-consuming and prone to operator errors. [Continues]

description: Self-supervised learning (SSL) has gained remarkable success, for which contrastive learning (CL) plays a key role. However, the recent development of new non-CL frameworks has achieved comparable or better performance with high improvement potential, prompting researchers to enhance these frameworks further. Assimilating CL into non-CL frameworks has been thought to be beneficial, but empirical evidence indicates no visible improvements. In view of that, this paper proposes a strategy of performing CL along the dimensional direction instead of along the batch direction as done in conventional contrastive learning, named Dimensional Contrastive Learning (DimCL). DimCL aims to enhance the feature diversity, and it can serve as a regularizer to prior SSL frameworks. DimCL has been found to be effective, and the hardness-aware property is identified as a critical reason for its success. Extensive experimental results reveal that assimilating DimCL into SSL frameworks leads to performance improvement by a non-trivial margin on various datasets and backbone architectures.

The Effect of Service Quality on Customer Satisfaction in Selected Insurance Companies in Addis Ababa
Creators: name: Awlachew, Akalu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The liberalization of the economic system in Ethiopia enabled the emergence of private insurance companies and have created competitive environment in the insurance industry. This study focused to examine the effect of service quality on customer satisfaction in selected insurance companies in Addis Ababa by applying SERVEQUAL model comprising five dimensions: Tangibility, reliability, responsiveness, assurance and empathy. The data collected from 141 questionnaires were analyzed using gap score, statistical tools such as mean, correlation and multiple regression analysis. The gap score between perception and expectation of customers of the insurance companies showed that there is a negative gap score in all service quality dimensions meaning those customers" expectations exceeds their perception. The study also indicated that the five service quality dimensions have positive and significant relationship with customer satisfaction. The study showed that the selected insurance companies in Addis Ababa were not providing the level of service quality demanded by customers. The findings suggested that the insurance companies need to improve all the dimensions of service quality. Keywords: SERVQUAL, Tangibility, Reliability, Responsiveness, Assurance, Empathy and customer satisfaction.

description: In recent years black hole configurations with non standard topology or with non-standard asymptotic have gained considerable attention. In this article we carry out numerical investigations aimed to find periodic coaxial configurations of co-rotating 3+1 vacuum black holes, for which existence and uniqueness has not yet been theoretically proven. The aimed configurations would extend Myers/Korotkin-Nicolai's family of non-rotating (static) coaxial arrays of black holes. We find that numerical solutions with a given value for the area A and for the angular momentum J of the horizons appear to exist only when the separation between consecutive horizons is larger than a certain critical value that depends only on A and |J|. We also establish that the solutions have the same Lewis's cylindrical asymptotic as Stockum's infinite rotating cylinders. Below the mentioned critical value the rotational energy appears to be too big to sustain a global equilibrium and a singularity shows up at a finite distance from the bulk. This phenomenon is a relative of Stockum's asymptotic's collapse, manifesting when the angular momentum (per unit of axial length) reaches a critical value compared to the mass (per unit of axial length), and that results from a transition in the Lewis's class of the cylindrical exterior solution. This remarkable phenomenon seems to be unexplored in the context of coaxial arrays of black holes. Ergospheres and other global properties are also presented in detail.

description: The design of an experiment can be always be considered at least implicitly Bayesian, with prior knowledge used informally to aid decisions such as the variables to be studied and the choice of a plausible relationship between the explanatory variables and measured responses. Bayesian methods allow uncertainty in these decisions to be incorporated into design selection through prior distributions that encapsulate information available from scientific knowledge or previous experimentation. Further, a design may be explicitly tailored to the aim of the experiment through a decision-theoretic approach using an appropriate loss function. We review the area of decision-theoretic Bayesian design, with particular emphasis on recent advances in computational methods. For many problems arising in industry and science, experiments result in a discrete response that is well described by a member of the class of generalised linear models. We describe how Gaussian process emulation, commonly used in computer experiments, can play an important role in facilitating Bayesian design for realistic problems. A main focus is the combination of Gaussian process regression to approximate the expected loss with cyclic descent (coordinate exchange) optimisation algorithms to allow optimal designs to be found for previously infeasible problems. We also present the first optimal design results for statistical models formed from dimensional analysis, a methodology widely employed in the engineering and physical sciences to produce parsimonious and interpretable models. Using the famous paper helicopter experiment, we show the potential for the combination of Bayesian design, generalised linear models and dimensional analysis to produce small but informative experiments.

Year: 2015

description: The reluctance of banks to effectively run Enterprise Risk Management program was the concern of NBE for years. This Project paper, therefore, is aimed to explore the practice of Enterprise Risk Management in Ethiopian Private Banks. Currently, there are 16 private commercial banks working in the country, some of which are celebrating their 20 years anniversaries. To represent all the 16 private banks, the researcher grouped them in to three categories. Dashen, Nib and Addis International banks were selected from each category in simple random sampling method. The data was collected through questionnaire and face to face interview. The questionnaires were distributed to Risk Committee members of the Board; senior executives of the bank management; Risk Management Unit personnel and Chief Controller of each bank. The interview was made with NBE's CBSD expert assigned by the Director. The research reveals that the practice is well understood by all stakeholders but is in its infant stage where continuous follow up and development requires.Key words: Enterprise Risk Management, Risk Management Program, Risk Management Unit, Chief Risk Officer, Credit Risk, Liquidity Risk

description: AI super-resolution, combining deep learning and N-body simulations has been shown to successfully reproduce the large scale structure and halo abundances in the Lambda Cold Dark Matter cosmological model. Here, we extend its use to models with a different dark matter content, in this case Fuzzy Dark Matter (FDM), in the approximation that the difference is encoded in the initial power spectrum. We focus on redshift z = 2, with simulations that model smaller scales and lower masses, the latter by two orders of magnitude, than has been done in previous AI super-resolution work. We find that the super-resolution technique can reproduce the power spectrum and halo mass function to within a few percent of full high resolution calculations. We also find that halo artifacts, caused by spurious numerical fragmentation of filaments, are equally present in the super-resolution outputs. Although we have not trained the super-resolution algorithm using full quantum pressure FDM simulations, the fact that it performs well at the relevant length and mass scales means that it has promise as technique which could avoid the very high computational cost of the latter, in some contexts. We conclude that AI super-resolution can become a useful tool to extend the range of dark matter models covered in mock catalogs.

description: When studying identity transitions, interview participants can find it difficult to reflect on their transitions and recall specific details related to past experiences. We present a new approach to enable participant reflection on past identity transitions, and a means to fill in blanks by eliciting data that may not otherwise come up: showing participants sentiment visualizations of their social media data. After detailing our methods of constructing sentiment visualizations, we discuss our experiences using them in a study on gender transition. For most participants, the visualizations elicited substantial reflection, and enabled recalling forgotten data and new interpretations of transition experiences. We guide researchers on how to use this method when studying other identity transitions; this may be especially powerful for marginalized people who undergo substantial identity changes. This article proposes a way to uncover participants’ personal histories, which can help HCI researchers to better understand and support marginalized people’s experiences

The Effect Of After Sales Service On Customers Retention The Case Of Tecno Mobile In Addis Ababa, Ethiopia
Creators: name: Workie, Zelalem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This research aims to study the effect of after-sales service on customer retention in case of Tecno Mobile, at Addis Ababa. The five independent variables namely; warranty, online support, provision of accessories, facility and equipment supply, maintenance and repair. The dependent variable was customer retention. Quantitative research method and non probability sampling technique (convenience) was applied. The results of the study revealed that the majorities of Tecno Mobile after sales service customers were moderately satisfied with the overall after sales service delivered by the company. But, online support and equipment supply seems somehow lacked great approval by customers since their response was lower than other variables even though the average score is met. The correlation result also proved that all five independent variables have strong and positive relationship with customer retention, dependent variable. The regression result also showed that the cumulative effect of independent variables on customer retention reached 62.4% .Normality test was also conducted and approved it the data were normally distributed.

description: An extended abstract accepted into the Dynamic Walking conference
description: Multilegged robots offer a potentially useful locomotion platform for both man-made and uncontrolled environments, as well as functioning as models for the scientific study of biological locomotion. Simple models, computable in faster than real time, are needed for design optimization, model based control, and comparative biomechanics. Commonly, models assume a non-slip contact with the substrate. We present an experimental study of hexapedal “steering”: gaits that allow turning while moving forward. Foot slipping is crucial for understanding these gaits in our robot. Surprisingly, increased slipping produces an improved ability to steer. Turning radii nearly halve and non-dimensional turning rates (deg/cycle) grow by 50% as the distance feet slip is doubled. Yet comparison of the foot motions in the body frame suggests that the geometry of leg motion remains virtually unchanged. We conclude that substantial work is needed to better understand and model multi-legged slipping, and relate body configuration changes to motion in the world frame.

Creators: name: Tegene, Dawit
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: In recent decades, the topic of after sales services get the highest attention in today's business across the globe since it impacts significantly the customers satisfaction. The general objective of the study was to investigate the factors that influence the customer satisfaction in related with after sales services domain on the telecom sector particularly the case of Ethio Telecom Key Account customers. A sample size of 147 was taken from Key Account customers located at Addis Ababa. Quantitative method of data collection was employed to collect the data through questionnaire. For the proper accomplishment of the study, the primary data were collected using Likert scale type questionnaire. Accordingly, 136 questionnaires were collected representing a 92.5 percent response rate. The study adopted quantitative method and the descriptive as well as inferential analysis has been done using SPSS Version 20. The major finding of the study indicated that after sales service quality i.e. provision of information, installation, billing service, customer complaint handling and enhanced service quality dimensions are positively & significantly affected the customer satisfaction except for one variable out of the total six variables. Moreover, 81.5% of the variations in customer satisfaction are explained by after sales services quality dimensions in Ethio Telecom. Based on the findings of the study, the researcher recommends the company to work on after sales services quality dimensions in providing enough information of product and services, make installations in highest quality with skilled professionals, dispatching quality bill to customers, manage customer complaints quickly and to give maximum focus on the dominate factor which is enhanced service quality (tangibility, reliability, responsiveness, assurance & empathy) to enhance the customer satisfaction.

description: We present X-ray observations of the recent outburst of 2022 from the neutron star low mass X-ray binary (LMXB) source 1A 1744-361. Spectral properties of the source have been analyzed using joint NuSTAR and NICER observations. During our observations, the source happens to be in the banana state (soft state) of the hardness intensity diagram (HID). In addition to a power-law with a high energy cutoff, the spectrum is found to exhibit broad iron $K_α$ emission along with distinct absorption features. A prominent absorption feature observed at 6.92 keV may be interpreted as $K_α$ absorption line from hydrogen-like iron. The absorption feature observed at 7.98 keV may be interpreted as a blend of Fe XXV and Ni XXVII transitions. We have summarized the evidence of variability of the spectral features observed in the X-ray continuum by time-resolved spectroscopy.

description: The escape phenomenon, mainly caused by thermal effects, is known as an obstacle to the further practical application of optical levitation system in vacuum. Irregular photophoresis induced by thermal effects can act as an amplifier of Brownian motion. Studies on this topic provide interpretation for particle escaping phenomenon during the pressure decreasing process, as well as valuable insights into the micro- and nanoscale thermal effects in optical trap in vacuum. In this paper, we derive and test a dynamic model for the motion of an optically levitated particle in a non-equilibrium state and demonstrate the escaping mechanism of heated particles. The result of theoretical investigations is consistent with experimental escape at 0.1mbar. This work reveals and provides a theoretical basis for the stable operation of laser levitated oscillator in high vacuum and pave the way for the practicability of ultra-sensitive sensing devices.

description: Physics-informed neural networks (PINNs) have been widely applied in different fields due to their effectiveness in solving partial differential equations (PDEs). However, the accuracy and efficiency of PINNs need to be considerably improved for scientific and commercial use. To address this issue, we systematically propose a novel dimension-augmented physics-informed neural network (DaPINN), which simultaneously and significantly improves the accuracy and efficiency of the PINN. In the DaPINN model, we introduce inductive bias in the neural network to enhance network generalizability by adding a special regularization term to the loss function. Furthermore, we manipulate the network input dimension by inserting additional sample features and incorporating the expanded dimensionality in the loss function. Moreover, we verify the effectiveness of power series augmentation, Fourier series augmentation and replica augmentation, in both forward and backward problems. In most experiments, the error of DaPINN is 1$\sim$2 orders of magnitude lower than that of PINN. The results show that the DaPINN outperforms the original PINN in terms of both accuracy and efficiency with a reduced dependence on the number of sample points. We also discuss the complexity of the DaPINN and its compatibility with other methods.

description: The purpose of this paper is to examine the contribution and effect of BPR factors on employee performance. Egalitarian leadership, cooperative working environment, top management commitment, management system, information technology and resistance to change are major factors dealt in the process. The first five factors are catalysts for positive employee performance whereas the sixth factor is affecting employee performance negatively. Capacity building and land administration bureaus are representing Addis Ababa City Administration. Twenty five percent of employees and two managers are considered for investigation. The researcher used questionnaire, interview, secondary documents and observation. These methods are used to collect data related with BPR factors and employee performance. Data presentation, analysis and interpretation are made with the aid of regression and descriptive statistics. Moreover, qualitative data is analyzed thematically. All, but top management commitment, have had positive impact on employee performance. In terms of contribution, cooperative-working environment is followed by managements system, resistance to change, egalitarian leadership, and information system. Findings, of top management commitment and resistance to change, show contradictory views against the theory advocated by the diamond model.

description: A recurrent neural network (RNN) is a universal approximator of dynamical systems, whose performance often depends on sensitive hyperparameters. Tuning of such hyperparameters may be difficult and, typically, based on a trial-and-error approach. In this work, we adopt a graph-based framework to interpret and characterize the internal RNN dynamics. Through this insight, we are able to design a principled unsupervised method to derive configurations with maximized performances, in terms of prediction error and memory capacity. In particular, we propose to model time series of neurons activations with the recently introduced horizontal visibility graphs, whose topological properties reflect important dynamical features of the underlying dynamic system. Successively, each graph becomes a layer of a larger structure, called multiplex. We show that topological properties of such a multiplex reflect important features of RNN dynamics and are used to guide the tuning procedure. To validate the proposed method, we consider a class of RNNs called echo state networks. We perform experiments and discuss results on several benchmarks and real-world dataset of call data records.

description: Electro-optically active low-bandgap conjugated copolymers were obtained by electrochemical polymerization (EP) in cholesteric liquid crystal (CLC). We prepared CLC electrolyte mixture blends of monomers, and electrochemically polymerized for obtaining conjugated copolymer with optical activity, in which the structure of the CLC is transferred, from achiral monomers on a CLC template. In addition, this copolymer showed a narrow bandgap and a significant red shift of the absorption band compared to the homopolymer. The optical rotatory dispersion (ORD) indicates that the polymer is chiroptically active and that the optical rotation can be tuned via redox. The guest monomers used for the EP in liquid crystal (LC) require solubility in the host LC and a rod-like structure, limiting their structural design. This technique has the advantage that complex synthesis of monomers is no required, and simple composition of monomers can be used to prepare copolymer films in a convenient manner by blending various monomers. This method expands the design range of optically active electrochromic devices based on conjugated polymers with pleochroic properties.

description: Supply chain management has become a potentially valuable way of securing competitive advantage and improving organizational performance since competition is no longer between organizations, but among supply chains. This is essentially due to the fact that supply chains account for as much as 70% of the product's cost, which by any measure speaks volumes about its significance. In Ethiopia the importance of supply chains in the manufacturing sector will continue receiving increased attention as the on-going industrialization in the country, the sugar manufacturing sector being one, would inevitably be facing a reality check in the form of competition from its global counterparts that by far have the competitive edge in embracing supply chain. The objectives of the study were 1) to identify the supply chain management practices being put in use by the selected three sugar manufacturing industries in Ethiopia; and 2) to determine the extent to which supply chain management practices are influencing the financial performance of the three sugar manufacturing companies (Metehara, Wonji and Fincha). The research design adopted was descriptive research design. Two sets of data – primary and secondary- were gathered. Primary data was collected using a questionnaire that consisted of both open and closed ended questions while secondary data was collected from the factories' financial records covering a period of seven years (2010-2016). The data collected was analyzed using descriptive statistics and also an inferential analysis involving multiple regressions was performed. The findings of the study were that supply chain across the three factories on average account for 55.1% of their annual cost entailing its worth to successful performance; that some of the supply chain management practices (knowledge management and information technology) had a positive effect on various parameters of financial performance of the factories while others (strategic supplier partnership and logistics outsourcing) do have a negative effect; and that effective implementation of supply chain management practices led to decrease in the operational cost of the factories, reduction on the response time for product design change, increased accuracy of order processing for customers which leads to improved profitability. The range of supply chain management practices embraced by the factories were found to be very limited to strategic supplier partnership, logistics outsourcing and IT infrastructure (accounting for 55.1% of the factories' cost, which is quite lower than the 70% in other countries). The study recommends that the management of the sugar factories should consider implementing various supply chain practices as appropriate.

description: We consider the pressureless Euler-Poisson equations with quadratic confinement. For spatial dimension $d\ge 2,\,d\ne 4$, we give a necessary and sufficient condition for the existence of radial global smooth solutions, which is formulated explicitly in terms of the initial data. This condition appears to be much more restrictive than the critical-threshold conditions commonly seen in the study of Euler-type equations. To obtain our results, the key observation is that every characteristic satisfies a periodic ODE system, and the existence of global smooth solution requires the period of every characteristic to be identical.

description: Polymers carrying different reactive groups that can be orthogonally functionalized are desirable for the design of multi-functionalizable materials. While several orthogonally functionalizable polymers have been reported, most of the work utilizes handles that are reactive toward different functional groups. However, examples of polymers that are orthogonally reactive toward molecules bearing the same functional group are rare. In this work, we report polymeric materials that can be sequentially functionalized using different amine-bearing molecules. Herein, we synthesized isocyanate and epoxide group containing copolymers, and investigated their sequential functionalization with amine-containing molecules. We show that such copolymers can be first functionalized with a particular amine-bearing molecule at room temperature, using conjugation through the isocyanate group. Thereafter, a different amine-containing molecule can be attached through the epoxy-amine reaction at 65 °C. Chemical characterizations of parent and subsequently functionalized copolymers were done by 1H NMR and FTIR spectroscopy techniques, to establish orthogonal functionalization. Additionally, the epoxide side chains were utilized as surface anchoring group after the functionalization of the polymer via isocyanate-amine reaction. This straightforward approach for obtaining orthogonally reactive amine-functionalizable copolymers, and surfaces derived thereof, would be attractive materials for various biomedical applications.
How Chinese Infrastructure Development Finance Affects Regime Ruling Parties

description: China has recently joined the upper ranks of the world’s foreign aid donor class, with much of its aid taking the form of large, capital-intensive infrastructure projects like power plants, highways, hospitals, and schools. This paper explores the theory that foreign development aid in the form of large infrastructure projects can incentivize an authoritarian regime to build out political party machinery for capturing the rewards of the project. Unlike natural resource windfalls or cash aid, local party officials hoping to leverage infrastructure development aid will need the capacity to hand out jobs as patronage, to direct contracts toward party loyalists, and to carefully manage project externalities to keep local voters happy. To test this mechanism, I conducted a quantitative analysis using China’s infrastructure development aid, V-Dem’s political party capacity rankings, and regime party vote share changes. While the results are inconclusive, the thesis suggests avenues for future testing and research.

Characteristic Functions for Cosmological Cross-Correlations

description: We introduce a novel unbiased, cross-correlation estimator for the one-point statistics of cosmological random fields. One-point statistics are a useful tool for analysis of highly non-Gaussian density fields, while cross-correlations provide a powerful method for combining information from pairs of fields and separating them from noise and systematics. We derive a new Deconvolved Distribution Estimator that combines the useful properties of these two methods into one statistic. Using two example models of a toy Gaussian random field and a line intensity mapping survey, we demonstrate these properties quantitatively and show that the DDE can be used for inference. This new estimator can be applied to any pair of overlapping, non-Gaussian cosmological observations, including large-scale structure, the Sunyaev-Zeldovich effect, weak lensing, and many others.

description: We consider a two-dimensional model of three species in rock-paper-scissors competition and study the self-organisation of the population into fascinating spiraling patterns. Within our individual-based metapopulation formulation, the population composition changes due to cyclic dominance (dominance-removal and dominance-replacement), mutations, and pair-exchange of neighboring individuals. Here, we study the influence of mobility on the emerging patterns and investigate when the pair-exchange rate is responsible for spiral waves to become elusive in stochastic lattice simulations. In particular, we show that the spiral waves predicted by the system's deterministic partial equations are found in lattice simulations only within a finite range of the mobility rate. We also report that in the absence of mutations and dominance-replacement, the resulting spiraling patterns are subject to convective instability and far-field breakup at low mobility rate. Possible applications of these resolution and far-field breakup phenomena are discussed.
