Factors influencing penetration of microinsurance in Ethiopia
Creators: name: Bulti, Abdi
Publisher: name: Zenodo
Year: 2018

description: The purpose of this study is to identify the factors influencing penetration of micro-insurance in Ethiopian insurance companies. The study adopts a cross-sectional quantitative technique with descriptive and analytical design based on primary data sampled using non probability sampling from 110 executive managements of five insurance companies providing microinsurance and nine years data from the same companies. Five (5) key factors affecting microinsurance penetration in Ethiopia are identified. The Multiple Linear regression model was used for analyising regression results and all relevant diagnostic tests were conducted to validate results. Empirical investigation using the Multiple Linear regression model indicates client awareness, income Level and trust having positive and significant impact on microinsurance penetration rate. Whereas product Price of microinsurance have negative and significant impact on microinsurance penetration rate. The study therefore recommends, amongst other things, intensive awareness creation campaign by all stakeholders about microinsurance product and its benefit among low income people, setting price that does not compromise the ability of clients to pay for essential items such as food and shelter, build trust and provide incentive like tax exemption on microinsurance transaction for provider and put coercive low for non provider to participate in providing microinsurance products taking in to consideration the double advantages that it has in protecting the poor from unexpected loss and alleviating poverty. In addition the government must integrate micro insurance program into its grand strategy in poverty reduction and Growth and transformation plan in striving to become middle income country by 2025

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: In this paper, we address the problem of efficient routing in delay tolerant network. We propose a new routing protocol dubbed as ORION. In ORION, only a single copy of a data packet is kept in the network and transmitted, contact by contact, towards the destination. The aim of the ORION routing protocol is twofold: on one hand, it enhances the delivery ratio in networks where an end-to-end path does not necessarily exist, and on the other hand, it minimizes the routing delay and the network overhead to achieve better performance. In ORION, nodes are aware of their neighborhood by the mean of actual and statistical estimation of new contacts. ORION makes use of autoregressive moving average (ARMA) stochastic processes for best contact prediction and geographical coordinates for optimal greedy data packet forwarding. Simulation results have demonstrated that ORION outperforms other existing DTN routing protocols such as PRoPHET in terms of end-to-end delay, packet delivery ratio, hop count and first packet arrival.

description: In this article we present calculations which indicate that nanoshells can be used as a high pressure gauge in Diamond Anvil Cells (DACs). Nanoparticles have important advantages in comparison with the currently used ruby fluorescence gauge. Because of their small dimensions they can be spread uniformly over a diamond surface without bridging between the two diamond anvils. Furthermore their properties are measured by broad band optical transmission spectroscopy leading to a very large signal-to-noise ratio even in the multi-megabar pressure regime where ruby measurements become challenging. Finally their resonant frequencies can be tuned to lie in a convenient part of the visible spectrum accessible to CCD detectors. Theoretical calculations for a nanoshell with a SiO2 core and a golden shell, using both the hybridization model and Mie theory, are presented here. The calculations for the nanoshell in vacuum predict that nanoshells can indeed have a measurable pressure-dependent optical response desirable for gauges.However when the nanoshells are placed in commonly used DAC pressure media, resonance peak positions as a function of pressure are no longer single-valued and depend on the pressure media, rendering them impractical as a pressure gauge. To overcome these problems an alternative nanoparticle is studied: coating the nanoshell with an extra dielectric layer (SiO2) provides an easy way to shield the pressure gauge from the influence of the medium, leaving the compression of the particle due to the pressure as the main effect on the spectrum. We have analyzed the response to pressure up to 200 GPa. We conclude that a coated nanoshell could provide a new gauge for high-pressure measurements that has advantages over current methods.

Performance-Optimum Superscalar Architecture for Embedded Applications

Year: 2012

description: Embedded applications are widely used in portable devices such as wireless phones, personal digital assistants, laptops, etc. High throughput and real time requirements are especially important in such data-intensive tasks. Therefore, architectures that provide the required performance are the most desirable. On the other hand, processor performance is severely related to the average memory access delay, number of processor registers and also size of the instruction window and superscalar parameters. Therefore, cache, register file and superscalar parameters are the major architectural concerns in designing a superscalar architecture for embedded processors. Although increasing cache and register file size leads to performance improvements in high performance embedded processors, the increased area, power consumption and memory delay are the overheads of these techniques. This paper explores the effect of cache, register file and superscalar parameters on the processor performance to specify the optimum size of these parameters for embedded applications. Experimental results show that although having bigger size of these parameters is one of the performance improvement approaches in embedded processors, however, by increasing the size of some parameters over a threshold value, performance improvement is saturated and especially in cache size, increments over this threshold value decrease the performance.

description: We report on our analysis of the Coulomb singularity problem in the frame of the coupled channel scattering theory including spin-orbit interaction. We assume that the coupling between the partial wave components involves orbital angular momenta such that $Δl = 0, \pm 2$. In these conditions, the two radial functions, components of a partial wave associated to two values of the angular momentum $l$, satisfy a system of two second-order ordinary differential equations. We examine the difficulties arising in the analysis of the behavior of the regular solutions near the origin because of this coupling. First, we demonstrate that for a singularity of the first kind in the potential, one of the solutions is not amenable to a power series expansion. The use of the Lippmann-Schwinger equations confirms this fact: a logarithmic divergence arises at the second iteration. To overcome this difficulty, we introduce two auxilliary functions which, together with the two radial functions, satisfy a system of four first-order differential equations. The reduction of the order of the differential system enables us to use a matrix-based approach, which generalizes the standard Frobenius method. We illustrate our analysis with numerical calculations of coupled scattering wave functions in a solid-state system.

description: We suggest here a novel nano-laminate, 5[Fe]/2[W$_x$Re$_{1-x}$] (x=0.6-0.8), with enhanced magnetic hardness in combination with a large saturation moment. The calculated magnetic anisotropy of this material reaches values of 5.3-7.0 MJ/m$^3$, depending on alloying conditions. We also propose a recipe in how to identify other novel magnetic materials, such as nano-laminates and multilayers, with large magnetic anisotropy in combination with a high saturation moment.

description: Numerous deep learning techniques have been explored in pursuit of achieving precise road segmentation; nonetheless, this task continues to present a significant challenge. Exposing shadows and the obstruction of objects are the most important difficulties associated with road segmentation using optical image data alone. By incorporating additional data sources, such as LiDAR data, the accuracy of road segmentation can be improved in areas where optical images are insufficient to segment roads properly. The missing information in spectral data due to the object blockage and shadow effect can be compensated by the integration of 2D and 3D information. This study proposes a feature-wise fusion strategy of optical images and point clouds to enhance the road segmentation performance of a deep learning model. For this purpose, high-resolution satellite images and airborne LiDAR point cloud collected over Florida, USA, were used. Eigenvalue-based and geometric 3D property-based features were calculated based on the LiDAR data. These optical images and LiDAR-based features were used together to train, end-to-end, a deep residual U-Net architecture. In this strategy, the high-level features generated from optical images were concatenated with the LiDAR-based features before the final convolution layer. The consistency of the proposed strategy was evaluated using ResNet backbones with a different number of layers. According to the obtained results, the proposed fusion strategy improved the prediction capacity of the U-Net models with different ResNet backbones. Regardless of the backbone, all models showed enhancement in prediction statistics by 1% to 5%. The combination of optical images and LiDAR point cloud in the deep learning model has increased the prediction performance and provided the integrity of road geometry in woodland and shadowed areas.

description: Agricultural extension is a form of rural development that relies on non-formal education. It is an old curriculum that works hand in hand with applied and academic agricultural scientific research. There is a wide debate about the necessity of separating the skills of the researcher from those of the agricultural extension worker. This study demonstrates what a scientific specialist needs to be a crucible that combines academic foundation, research mastery, and agricultural advisor skills. In this popular article, a quick presentation of the contents of 11 academic lectures separated into 10 sections on agricultural extension targeting master's students in plant protection at the University of Debrecen, Hungary. In the summary, a skilled agricultural supervisor needs broad academic capabilities, integrated research, scientific applications skills, and social characteristics, as well as the use of various media to understand the needs of the local community and build extension plans to affect the adoption of qualitative technologies that contribute to rural agricultural development. The article recommends the necessity to raise awareness on the importance of combining the characteristics of an academic, researcher, and agricultural advisor in agricultural societies.

description: The generalised-geometric formulation of 10-dimensional supergravity suggests a particular simple "limit", which results in a theory whose only dynamical degrees of freedom are the dilaton and the dilatino. The theory is still invariant both under generalised diffeomorphisms and a local supersymmetry and in many aspects is structurally similar to the original supergravity, which makes it a convenient playground for understanding more subtle aspects of the full physical setup. In particular, the simplicity and the geometric nature of the dilatonic theory allow us to build a full BV extension to all orders in the fermionic variables.

Dadurch entsteht eine Kette der Abwerbung und Abwanderung, die an verschiedensten Stellen der Welt immer wieder zu Lücken im Personalbestand führt und damit die Stabilität der Gesundheitssysteme vor Ort gefährdet. Die WHO versucht, dem mit einem Verhaltenskodex zu begegnen, der eine ethische Praxis der Anwerbung, Gleichbehandlung, internationale Kooperation und vieles mehr thematisiert. Ziel dieser Arbeit ist es, den Kodex und die behandelten Problemstellungen aus christlich-sozialethischer Perspektive zu beleuchten und mittels der Prinzipien Personalität, Subsidiarität, Solidarität und Nachhaltigkeit zu einer sozialethischen Beurteilung des Verhaltenskodex der WHO zu gelangen.

A critique of just war theory

Publisher: name: University of Calgary
Year: 2003

description: Bibliography: p. 229-231
description: Just war theory is a moral tradition that sets out the criteria that must be met for a war to be morally justified. In this dissertation, I undertake a critical analysis of those criteria. That analysis often makes use of an analogy with individual self-defense theory. Therefore, as part of the introductory chapter, I point to the parallels between international military conflict and domestic self-defense, and I also describe the strengths and limitations of the analogy between the two theories. I then turn to the ad helium criteria, arguing that the right intention criterion should not be included in the criteria, and that the reasonable hope of success criterion is redundant. As for the competent authority criterion, I argue that its inclusion is appropriate, but that the criterion cannot be used by an unjust enemy to demonstrate that he is being treated unjustly. With respect to the central criteria of just cause, last resort, and proportionality, I provide my own accounts of them. In considering the in hello criteria, I begin by arguing that there is a closer relationship between in hello and ad helium criteria than is often contended. I then provide my own account of the in hello criteria. In particular, I develop an account of the discrimination criterion that does not rely on considerations of intention. In the final chapter of the dissertation, I discuss some comparative weighing principles that are relevant in applying the ad helium proportionality and last resort criteria and the in hello proportionality and necessity criteria.
Assessment of left ventricular diastolic suction using wave-intensity analysis

Publisher: name: University of Calgary

description: Bibliography: p. 85-94
description: Left ventricular diastolic suction (LV DS) is defined as the property of the LV to refill itself during early diastole, independent of any force from the left atrium (LA). Two different mechanisms have been developed to explain this phenomenon. The first mechanism relates DS to the decrease in L V elastance. The second theory, relates DS to negative L V pressure, suggesting that the smaller the end-systolic volume, the greater the DS. In an attempt to reconcile these two mechanisms, wave-intensity analysis was used. The purpose of this study was to illustrate that Iw-BE (L V generated backward expansion wave) depends on both decreasing elastance and the L Vend-systolic volume. It was found that the energy ofLV DS is inversely proportional to -c and LV end-systolic volume. From these data a 3-D plot was formed demonstrating the non-linear dependence of L V DS on both of these variables.

description: The linear Kelvin{Voigt operator L_εis a typical example of wave operator L_0 perturbed by higher-order viscous terms as \epsilonu_xxt. If Pεis a prefixed boundary value problem for L_ε, when ε= 0, L_εturns into L_0 and P_εinto a problem P_0 with the same initial{boundary conditions of Pε. Boundary layers are missing and the related control terms depending on the fast time are negligible. In a small time interval, the wave behavior is a realistic approximation of u_εwhen ε\rightarrow 0. On the contrary, when t is large, diffusion effects should prevail and the behavior of u_εfor ε\rightarrow 0 and t \rightarrow 1 should be analyzed. For this, a suitable functional correspondence between the Green functions G_εand G_0 of P_epsilon and P_0 is derived and its asymptotic behavior is rigorously examined. As a consequence, the interaction between diffusion effects and pure waves is evaluated by means of the slow time \epsilont; the main results show that in time intervals as (ε; 1/epsilon) pure waves are quasi-undamped, while damped oscillations predominate as from the instant t > 1/ε.

description: Because sensor nodes operate on power limited batteries, sensor functionalities have to be designed carefully. In particular, designing energy-efficient packet forwarding is important to maximize the lifetime of the network and to minimize the power usage at each node. This paper presents a Geographic Energy-Aware Multipath Stream-based (GEAMS) routing protocol for WMSNs. GEAMS routing decisions are made online, at each forwarding node in such a way that there is no need to global topology knowledge and maintenance. GEAMS routing protocol performs load-balancing to minimize energy consumption among nodes using twofold policy: (1) smart greedy forwarding and (2) walking back forwarding. Performances evaluations of GEAMS show that it can maximize the network lifetime and guarantee quality of service for video stream transmission in WMSNs.

description: Using the formalism of the interaction picture we calculate an expression for the Wightman function for only the spherically symmetric modes of a quantum Klein-Gordon scalar field in a general Vaidya spacetime with ingoing null dust. It is demonstrated that particle detectors following time-like trajectories that are in the ground state at some time outside of the collapsing shell will respond independently from the configuration of the ingoing null dust if the response is taken at any time outside of the collapsing shell. For detectors that are taken to be in the ground state at a time interior to the shell it is shown that their response will depend on the configuration of the ingoing null dust. Relevance to the information loss paradox is discussed.

description: This study examined the relationship between the Canadian Cognitive Abilities Test (CCAT) and the Wechsler Intelligence Scale for Children - Third Edition (WISC-III) using archival data pertaining to a sample of 279 students with learning difficulties. A significant correlation (r =.43) was found between the CCAT Composite Standard Age Score (SAS) and WISC-III Full Scale IQ. Significant correlations between Verbal and Nonverbal CCAT SASs and WISC-III Verbal and Performance IQs were .35 and .42, respectively. Significant correlations between Verbal, Nonverbal, and Quantitative CCAT SASs and corresponding WISC-111 Index scores were .31, .43, and .31. WISC-111 mean IQ/Index scores were significantly higher than CCAT mean SASs for composite, verbal and nonverbal comparisons, while the CCAT Quantitative SAS mean did not differ significantly from the WISC-III Freedom from Distractibility Index mean. Discrepancies between participants' CCAT and WISC-III composite scores are reported. Directions for future research and implications for practice are discussed.

Given a smoothing of a projective surface X of this type, we construct an associated exceptional vector bundle on the nearby fiber Y in the case H^{2,0}(Y)=H^1(Y)=0. If Y is the projective plane we show that our construction establishes a bijective correspondence between the possible degenerate surfaces X and exceptional bundles on Y modulo dualizing and tensoring by line bundles. If Y is of general type then our construction establishes a connection between components of the boundary of the moduli space of surfaces deformation equivalent to Y and exceptional bundles on Y.

As is the case of NN forces previously considered, we show that 3NF have repulsions at short distance at 1--loop, which becomes exact in the short distance limit thanks to the asymptotic freedom of QCD. Moreover these behaviors are universal in the sense that they do not depend on the energy of the NBS wave function for 3 nucleons.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We study the linear instability with respect to necking of a filament of polymeric fluid undergoing uniaxial extension. Contrary to the widely discussed Considere criterion, we find the onset of instability to relate closely to the onset of downward curvature in the time (and so strain) evolution of the zz component of the molecular strain, for extension along the z axis. In establishing this result numerically across five of the most widely used models of polymer rheology, and by analytical calculation, we argue it to apply generically. Particularly emphasized is the importance of polymer chain stretching in partially mitigating necking. We comment finally on the relationship between necking and the shape of the underlying steady state constitutive curve for homogeneous extension.

description: Feedback control of open quantum systems is of fundamental importance for practical applications in various contexts, ranging from quantum computation to quantum error correction and quantum metrology. Its use in the context of thermodynamics further enables the study of the interplay between information and energy. However, deriving optimal feedback control strategies is highly challenging, as it involves the optimal control of open quantum systems, the stochastic nature of quantum measurement, and the inclusion of policies that maximize a long-term time- and trajectory-averaged goal. In this work, we employ a reinforcement learning approach to automate and capture the role of a quantum Maxwell's demon: the agent takes the literal role of discovering optimal feedback control strategies in qubit-based systems that maximize a trade-off between measurement-powered cooling and measurement efficiency. Considering weak or projective quantum measurements, we explore different regimes based on the ordering between the thermalization, the measurement, and the unitary feedback timescales, finding different and highly non-intuitive, yet interpretable, strategies. In the thermalization-dominated regime, we find strategies with elaborate finite-time thermalization protocols conditioned on measurement outcomes. In the measurement-dominated regime, we find that optimal strategies involve adaptively measuring different qubit observables reflecting the acquired information, and repeating multiple weak measurements until the quantum state is "sufficiently pure", leading to random walks in state space. Finally, we study the case when all timescales are comparable, finding new feedback control strategies that considerably outperform more intuitive ones. We discuss a two-qubit example where we explore the role of entanglement and conclude discussing the scaling of our results to quantum many-body systems.

description: For the Harry Dym hierarchy, a non-standard Lax formulation is deduced from that of Korteweg-de Vries (KdV) equation through a reciprocal transformation. By supersymmetrizing this Lax operator, a new N=2 supersymmetric extension of the Harry Dym hierarchy is constructed, and is further shown to be linked to one of the N=2 supersymmetric KdV equations through superconformal transformation. The bosonic limit of this new N=2 supersymmetric Harry Dym equation is related to a coupled system of KdV-MKdV equations.

KIC 1571511B: A Benchmark Low-Mass Star In An Eclipsing Binary System In The Kepler Field

description: KIC 1571511 is a 14d eclipsing binary (EB) in the Kepler dataset. The secondary of this EB is a very low mass star with a mass of 0.14136 +/- 0.00036 M_sun and a radius of 0.17831 +0.00051/-0.00062 R_sun (statistical errors only). The overall system parameters make KIC 1571511B an ideal "benchmark object": among the smallest, lightest and best-described stars known, smaller even than some known exoplanet. Currently available photometry encompasses only a small part of the total: future Kepler data releases promise to constrain many of the properties of KIC 1571511B to unprecedented level. However, as in many spectroscopic single-lined systems, the current error budget is dominated by the modeling errors of the primary and not by the above statistical errors. We conclude that detecting the RV signal of the secondary component is crucial to achieving the full potential of this possible benchmark object for the study of low mass stars.

title: Fusion Bonding Behavior of 3D Printed PA6/CF Composites Via Post Fabrication Compaction
Creators: name: Fernandez Mediavilla, Gonzalo
Publisher: name: Old Dominion University Libraries
Year: 2023

description: Additive manufacturing (AM) is becoming a robust production technology for aerospace, healthcare, and construction industries among others. Fused Deposition Modelling (FDM) is one of the methods most used to 3D print products. FDM has limitation due to interlayer adhesion and restriction imposed by the printing direction. Specially with AM composites, as reinforced nylon PA6 with short fibers, parts show more strength along the direction of the filament due to the alignment of the carbon fibers, but weaker in other directions. The proposed method to solve this issue is to print parts separately and join them together by fusion bonding. PA6/CF dovetail and simple lap joint samples were designed to study the optimal procedure for fusion bonding using Talc Bed Compaction Molding (TBCM), and were tested using mechanical tensile testing processes, comparing tensile stress characteristics to the specifications provided by Desktop Metal and reference results from 3D printed, untreated samples. This analysis was used to test T-brackets designed with subparts printed in different directions, to verify the procedure was optimal. The results indicate that T-bracket configuration after using TBCM show an increase of strength and elongation of 144%. Also, TBCM can improve the internal structure quality in 3D printed parts, limit the number of voids, and create strong bonds between PA6/CF. This paper will discuss the optimal fusion bonding procedure and the bonding strength analysis of PA6/CF using TBCM.

RXTE Observations of Anomalous X-ray Pulsar 1E 1547.0-5408 During and After its 2008 and 2009 Outbursts

description: We present the results of Rossi X-ray Timing Explorer (RXTE) and Swift monitoring observations of the magnetar 1E 1547.0-5408 following the pulsar's radiative outbursts in 2008 October and 2009 January. We report on a study of the evolution of the timing properties and the pulsed flux from 2008 October 4 through 2009 December 26. We show that the pulsed flux decrease which followed an initial rise in the 2008 outburst was interrupted by a spike ~9 days after the initial outburst. In our timing study, a phase-coherent analysis shows that for the first 29 days following the 2008 outburst, there was a very fast increase in the magnitude of the rotational frequency derivative nudot, such that the second derivative was a factor of ~60 larger than that reported in data from 2007. This nudot magnitude increase occurred in concert with the decay of the pulsed flux following the start of the 2008 event. Following the 2009 outburst, for the first 23 days, the second derivative was consistent with zero, and nudot had returned to close to its 2007 value. In contrast to the 2008 event, the 2009 outburst showed a major increase in persistent flux, relatively little change in the pulsed flux, and sudden significant spectral hardening ~15 days after the outburst. We show that, excluding the month following each of the outbursts, and because of the noise and the sparsity in the data, multiple plausible timing solutions fit the pulsar's frequency behavior. We note similarities in the behavior of 1E 1547.0-5408 following the 2008 outburst to that seen in the AXP 1E 1048.1-5937 following its 2001-2002 outburst and discuss this in terms of the magnetar model.

description: Transitioning from fossil fuel supplied energy to renewable technology must meet cost efficient parameters throughout the manufacturing process while possessing the characteristics of a functioning and reliable power source. With a significant demand in renewable energy products, developmental techniques require adaptive approaches and procedures for novel materials in the manufacturing phase. This report proposes how a solid oxide fuel cell (SOFC), a renewable energy system, can employ additive manufacturing for directly 3D printing its components by utilizing stereolithography (SLA) 3D printing techniques. Fabrication of the printed components from the mixtures were first mixed with varying concentrations of ceramic powder and resin. The application of SLA 3D printing was then evaluated by printing SOFC components from the various component mixtures. Following the fabrication of the components, the reliability of the additive materials was analyzed through characterization of the components. To do this, the components were first sintered with various heating curves, adjusting for the generation of solid component products. Then, the components had their surfaces topographically imaged for microstructure characterization through a scanning electron microscope (SEM). The resulting analysis of the porosity value corresponds to the performance potential of that component. Thus, verifying the material properties succeeding the fabrication of SOFC components via SLA 3D printing techniques.

Year: 2012
Subjects: subject: Genomics (q-bio.GN)
subject: FOS: Biological sciences

description: Two-dimensional gel electrophoresis has been instrumental in the development of proteomics. Although it is no longer the exclusive scheme used for proteomics, its unique features make it a still highly valuable tool, especially when multiple quantitative comparisons of samples must be made, and even for large samples series. However, quantitative proteomics using 2D gels is critically dependent on the performances of the protein detection methods used after the electrophoretic separations. This chapter therefore examines critically the various detection methods (radioactivity, dyes, fluorescence, and silver) as well as the data analysis issues that must be taken into account when quantitative comparative analysis of 2D gels is performed.
