description: We perform a calculation of the cross section for nine reactions induced by $\bar K$ scattering on protons. The reactions studied are $K^-p \to Λπ^+ π^-$, $K^-p \to Σ^0 π^+ π^-$, $K^-p \to Λπ^0 η$, $K^-p \to Σ^0 π^0 η$, $K^-p \to Σ^+ π^- η$, $\bar K^0 p \to Λπ^+ η$, $\bar K^0 p \to Σ^0 π^+ η$, $\bar K^0 p \to Σ^+ π^+ π^-$, $\bar K^0 p \to Σ^+ π^0 η$. We find that in the reactions producing $π^+ π^-$ a clear peak for the $f_0(980)$ resonance is found, while no trace of $f_0(500)$ appears. Similarly, in the cases of $πη$ production a strong peak is found for the $a_0(980)$ resonance, with the characteristic strong cusp shape. Cross sections and invariant mass distributions are evaluated which should serve, comparing with future data, to test the dynamics of the chiral unitary approach used for the evaluations and the nature of these resonances.

description: For the application of Potential-Induced Degradation detection via dark current-voltage curve measurement, the temperature dependency of electrical module parameters plays a vital role. For the detection of shunting-type PID, the shunt resistance can serve as an indicator. The experiments show that the shunt resistance of Copper-Indium-Gallium-Selenide Thin-Film modules is strongly temperature dependent. In a 90 K range between -10 °C and 85 °C, the shunt resistances of two modules from two different manufacturers both show a negative temperature coefficient over the whole temperature interval. For module A, the shunt resistance changes by a factor of around five and for module B, the factor is around three. The decrease of the shunt resistance with increasing temperature is monotonically decreasing and non-linear for both modules. The correlation between temperature and shunt resistance does not show any hysteresis effect.

PV Module Design, Manufacture, Performance and Reliability

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 776-778
description: We present results of full size bifacial PV module combining Silicon Heterojunction (SHJ) solar cells and Shingle interconnection. SHJ solar cells, based on crystalline silicon (c-Si) absorber and thin hydrogenated amorphous silicon (a-Si:H) passivation and selective contacts, have demonstrated to reach efficiencies higher than 25% at industrial scale. On the other hand, shingling technology applied to solar cell allows the elimination of the space between the cells; increases the active surface per module; removes exposed busbars, reducing the overall resistive losses and promoting a highly aesthetic appearance. Moreover, shingling, due to low-temperature process, is completely suitable for HJT cells and is currently the only industrial solution compatible with thinner wafers (<120 um) and larger wafer formats. At present time, there are not commercial modules using both technology and there are very few data in literature. Previous studies on minimodules based on SHJ cells showed promising results in terms of both power output as well as reliability. In this work, we show the results of a full size bifacial PV module (72 cells equivalent), glass-to-glass assembled. We obtained 9% increment of power output on shingled module with respect to the reference module based on ECA- busbar interconnections. Shingling technology allows to reach a Cell-To-Module (CTM) factor equal to 1 and to maintain high bifaciality factor (>90%).

PV Module Design, Manufacture, Performance and Reliability

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 779-782
description: Solar photovoltaic (PV) module encapsulation technology has grown rapidly worldwide in the last few years. Various novel encapsulation materials have been introduced in the PV market. Thermoplastic polyolefin elastomer (POE) encapsulant is a highly relevant alternative to the most commonly used crosslinking ethylene-vinyl acetate copolymer (EVA). During lamination, encapsulation materials are frequently crosslinked or cured, which allows for reducing creep at elevated temperatures. Crosslinking agents based on organic peroxides are well established. The main objective of this paper was to implement an isothermal, dynamic-mechanical analysis (DMA) method to investigate and compare the crosslinking kinetics of EVA and POE encapsulants. Isothermal experiments were carried out in torsional mode at different temperatures. The gelation point was deduced from the crossover-point of the real and imaginary part of the modulus. Comparable activation energies (Ea) of 149 and 152 kJ/moles were obtained for EVA and POE, respectively. By assessment of complex viscosity, the degree of crosslinking was deduced. Interestingly, the degree of crosslinking at gelation point was a factor of about three higher for POE, which revealed a significantly lower viscosity in the fully cured state. This paper will help in understanding the crosslinking kinetics, which is very beneficial for the PV industry and encapsulant manufacturers for quickly assessing the modification of any encapsulant crosslinking process.

description: Building Integrated Photovoltaics (BIPV) is a potential solution for zero emission buildings. Different aspects ranging from aesthetics, yield, safety, cost, etc. need to be further developed to meet the requirement from the market for further growth. Shingle module technology is a very good approach for BIPV application due to the advantage on both aesthetics and energy output. However, the reliability of the shingle modules is an issue making the PV industry hesitant. Here, the shingle modules fabricated with two different kinds of adhesives were investigated. The electroluminescence image and current-voltage measurement shows that all the modules passed 1000 thermal cycles from -40oC to+85oC without failure.

description: The main objective of this paper is to assess the overall opportunities and challenges of lease financing service in development Bank of Ethiopia. Leasing is financing in kind and DBE has been providing lease financing service in the form of supplying capital goods to small and medium enterprises since 2016. The research approach adopted in this study was a mix of quantitative and qualitative approaches. Both primary and secondary data were used. In identifying the respondents from the study population, purposive sampling was adopted. All District offices of the Bank and selected work units from Head office were included in the sample. The study identified opportunities of lease financing and got high level of agreement by respondents. The level of agreement on opportunities questions responded as lease business sector, strong support from the government, leasing business opportunity for employment creation, new investment opportunity and contributing for SMEs development. The study also found out that the major internal and external challenges of the lease financing in DBE are high lease NPLs, tight lease requirements, lack of hard currency, inadequate MIS, policy and procedure amendments repeatedly, and lack of capital. Based on the survey and interview results the researcher forwarded its conclusion and recommendation.

description: Building integrated module technologies are expected to meet a growing market in the next years. In contrast to large-scale power plants, the optical appearance of the modules is a major criterion in addition to energy output for their success as building components. In particular, PV modules for architecture, display facades or urban noise protection may be individually designed by colored patterns based on ink-jet printing technologies. In our work, we set up an optical simulation tool that calculates energy output of colored PV modules from the optical properties of the bare printing inks. The model is experimentally tested using common inkjet inks for CMYK+W digital printing on glass substrates. Optical spectroscopy on specially prepared ink samples are implemented in order to provide the required transmission and reflection coefficients as input parameters. Simulated efficiency predictions can be performed for colored PV modules with various ink multilayer stacks and thus for different possible color shades obtained by subtractive color mixing. In case of a double-print-layer including white ink, we can improve the power loss estimation from about 20% obtained by a simple approach to about 5% accuracy by considering individual optical losses and gains in the layer stack.

description: The performance of multi-image alignment, bringing different images into one coordinate system, is critical in many applications with varied signal-to-noise ratio (SNR) conditions. A great amount of effort is being invested into developing methods to solve this problem. Several important questions thus arise, including: Which are the fundamental limits in multi-image alignment performance? Does having access to more images improve the alignment? Theoretical bounds provide a fundamental benchmark to compare methods and can help establish whether improvements can be made. In this work, we tackle the problem of finding the performance limits in image registration when multiple shifted and noisy observations are available. We derive and analyze the Cramér-Rao and Ziv-Zakai lower bounds under different statistical models for the underlying image. The accuracy of the derived bounds is experimentally assessed through a comparison to the maximum likelihood estimator. We show the existence of different behavior zones depending on the difficulty level of the problem, given by the SNR conditions of the input images. We find that increasing the number of images is only useful below a certain SNR threshold, above which the pairwise MLE estimation proves to be optimal. The analysis we present here brings further insight into the fundamental limitations of the multi-image alignment problem.

description: The purpose of this study was to investigate factors affecting the adoption of electronic payment on cash transfer program in Ethiopia in the case of M-Birr and Ethiopia Productive Safety Net Program (PSNP). A sample of 390 respondents were drawn from fifteen (15) woredas households of the four regional governments (Amhara, Oromia, SNNP and Tigray) of Ethiopia where a structured questionnaire was distributed to these samples. However, the response rate from among the intended samples was only 95.4% therefore; around 372 responses were found to be workable by this study. SPSS V 24.0 was used to analyze the data collected and to test the hypotheses put forward. Descriptive Research and Explanatory Research design was employed in order to identify the extent at which the independent variables affect the dependent variable. Multiple regression analysis was used in establishing the significance of the relationship. The findings of this study then show that factors namely convenience and relative advantage have a positive and significant relationship with electronic cash transfer adoption in Ethiopia which led to, the acceptance of hypothesis two and four. From hypothesis three, perceived risk was found to have a significant negative influence on electronic cash transfer adoption, meaning hypothesis three was supported. Whereas hypothesis one, trust has no significant relationship with the dependent variable electronic cash transfer adoption. These findings are beneficial for M-Birr and Productive Safety Net Program (PSNP) in Ethiopia to identify factors that influence the effectiveness of electronic cash transfer adoption. The study recommends M-Birr and Ethiopia Productive Safety Net Program (PSNP) to consider investing in campaigns and arranging information sessions to demonstrate the features of electronic cash transfer system, and its benefits over manual cash transfer system.

The course lasts four weeks and is situated at the end of the academic year. Students work on a project in randomly assigned groups of three students, and various activities are included to promote skill development. To enhance reflection on skill development, the ALACT model was implemented in the course. Three teachers-as-researchers were invited for individual semi-structured interviews to explore their experiences with the ALACT model and the use of reflection in the MDPhar course. This document describes the questions asked during the interview, and to which phase(s) of the ALACT model the questions relate.
description: Although questions for the semi-structured interview were designed in English, the interviews themselves were held in Dutch, as this was the primary language for both the interviewer and the interviewees. The Dutch translation of these questions was corroborated by a second author.

description: This study aimed at assessing the relationship between front office employee's job satisfaction and individual customer's satisfaction in Commercial Bank of Ethiopia. Two independent surveys, one measuring the job satisfaction level of the front office employees and the other measuring the satisfaction level of the customers were performed using two data collection instruments to obtain the primary data for this research. The questionnaires were distributed to 351 sample front office employees and 384 customers of the Bank. 337 front office employees and 373 customers responded to the survey and used for analysis. The participants of the study were selected using convenience-non-random selection method. Descriptive statistics, Pearson's correlation and regression analysis were used to examine and analyze the data. The results indicated low level of satisfaction on both front office employee's job satisfaction and customer's satisfaction. A Pearson's correlation analyses result of a 93.5 percent correlation with a significance of p = 0.000 which is less than α = 0.05 and the regression analysis indicates that a positive and statistically significant relationship between front office employee's job satisfaction and customer satisfaction levels does exist. Finally it is recommended that the Bank should work on the factors that has been identified to have low satisfaction score on both sides and to develop ways in order to satisfy its front office employee's job satisfaction so as to increase its customer's satisfaction.

description: We address the issue of visual saliency from three perspectives. First, we consider saliency detection as a frequency domain analysis problem. Second, we achieve this by employing the concept of {\it non-saliency}. Third, we simultaneously consider the detection of salient regions of different size. The paper proposes a new bottom-up paradigm for detecting visual saliency, characterized by a scale-space analysis of the amplitude spectrum of natural images. We show that the convolution of the {\it image amplitude spectrum} with a low-pass Gaussian kernel of an appropriate scale is equivalent to such an image saliency detector. The saliency map is obtained by reconstructing the 2-D signal using the original phase and the amplitude spectrum, filtered at a scale selected by minimizing saliency map entropy. A Hypercomplex Fourier Transform performs the analysis in the frequency domain. Using available databases, we demonstrate experimentally that the proposed model can predict human fixation data. We also introduce a new image database and use it to show that the saliency detector can highlight both small and large salient regions, as well as inhibit repeated distractors in cluttered images. In addition, we show that it is able to predict salient regions on which people focus their attention.

description: We demonstrate that partial shading of a single c-Si solar cell in a state-of-the-art high-power photovoltaic (PV) module with three bypass diodes can result in hot cells with critical module peak temperatures of 196 °C. The PV module under test features 144 bi-facial PERC+ half-cells of M6 silicon wafer format with a cell area of (166 x 83) mm2. The module’s measured maximum power output is 437 WP. We test three cells of the PV module in an extended IEC 61215-2 MQT09 hot-spot endurance test for 5 h in a steady-state sun simulator. All shaded cells reach steady-state temperatures above 175 °C. For the hottest cell we measure peak temperatures of 196 °C at the module surface. After the test the PV modules shows a discoloration of the white backsheet at the position of the shaded solar cells. This is likely to result in a module power loss or module failure due to encapsulation discolorations, desoldering of the cell interconnection, backsheet cracking of even glass breakage. Our results are essential for improving the long-term stability of new high-power modules with M10- or M12-sized cells and power outputs over 500 WP against partial shading. New high-power modules require hot cell mitigation techniques that go beyond three bypass diodes per module or heat-resistant module materials.
The Role of Banking Sector In Capital Accumulation and Economic Growth of Ethiopia: An application of ARDL approach to Co-integration
Creators: name: Tadesse, Yirgu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Economists have been arguing regarding the importance of financial development for economic growth. In this connection, the study examine the effect of the role of banking sector on capital accumulation and economic growth of Ethiopia using time series data from 1981 to 2016. The model estimation includes unit root tests, co-integration test using ARDL approach, granger non-causality tests and investigates the short-run and long-run dynamics using VECM. The result of the analysis shows that, in the short-run, deposit has a significantly positive effect on capital accumulation and economic growth; whereas credit has only significant effect on short-run capital accumulation. On the other hand, except deposit which has significant effect on economic growth, the role of banking sector, as measured by deposit and credit, appeared as having no significant effect on long-run capital accumulation & economic growth. It's expected that capital accumulation has a significantly positive effect on long-run economic growth. The analysis made to determine the direction of causality shows the existence of bidirectional causality between deposit and economic growth, while there is a unidirectional causality running from economic growth to credit. The study has only found a unidirectional causality running from capital accumulation to deposit and credit. This confirms the fact that banking sector of the country is not in a position to support long-run investment need which is a precondition for sustainable economic growth. As a result the study recommends policymakers to strengthen the capacity of the banking sector in a way that would mobilize higher savings and efficiently allocate to most productive sector of the economy, so that the country will attain rapid capital accumulation and sustainable economic growth.

description: We propose a multiple-range quantum communication channel to realize coherent two-way quantum state transport with high fidelity. In our scheme, an information carrier (a qubit) and its remote partner are both adiabatically coupled to the same data bus, i.e., an N}-site tight-binding chain that has a single defect at the center. At the weak interaction regime, our system is effectively equivalent to a three level system of which a coherent superposition of the two carrier states constitutes a dark state. The adiabatic coupling allows a well controllable information exchange timing via the dark state between the two carriers. Numerical results show that our scheme is robust and efficient under practically inevitable perturbative defects of the data bus as well as environmental dephasing noise.

description: Lightweight photovoltaic (PV) modules are the key technology to access new markets such as industrial buildings and mobile applications. In this work we investigate methods to reduce the weight of a module while still being able to withstand mechanical loads according to IEC 61215. Finite element modelling (FEM) shows that increasing stiffness of the backsheet has more impact on the stress of the solar cells and displacement of the module under mechanical load than increasing the encapsulants stiffness. Therefore, two approaches are evaluated to increase the Young’s modulus and hence stiffness: Firstly, laminating glass fiber layer onto the rear side of a module and secondly laminating honeycomb structures into the module. The results show that an increase in Young’s modulus by glass fiber layers or honeycomb structures are sufficient to provide a significant rigidity to show a similar displacement during mechanical load tests as conventional module setups. Therefore, embedded glass fibers or honeycomb structures in the backsheet can be used to achieve lightweight modules with thinner or even without front glass. Additionally, backsheets with embedded glass fibers may be a viable option for modules with thinner front glass which currently require a rear glass.
The Practice and Challenge of Internal Auditing Function of Privately Owned Commercial Banks of Ethiopia in Light of International Accepted Auditing Standards and Principles

description: The aim of this study was to examine the practice and challenge of internal auditing function of privately owned commercial banks of Ethiopia in light of international accepted auditing standards and principles on selected 16 Ethiopian privately owned commercial banks. An interview data collection method was used. The study used semi-structured face to face interview to 8 purposely selected head of internal audit departments as a primary data. The findings of the study showed that majority of internal audit activities and responsibilities were practiced by all internal audit departments of commercial banks in line with accepted international auditing standards and principles. However, some internal audit departments faced challenges in the following areas of internal audit independence such as: non-existence of NBE involvement in the removal process of the head internal audit department; lower remuneration of head of internal audit department compared to others having equivalent status; failure to conduct an evaluation on board and sub-committee performance by some banks; the misconception of senior management and board of director/audit committee with respect to penalty imposed by NBE for the non-compliance as the result of internal audit report; not issuing RBIA framework or guidelines by NBE to have uniformity and consistency among all commercial banks; NBE"s instruction to widening the audit coverage which is contradictory with RBIA methodology; and branch residence auditors are mainly engaged in routine checking activities of the internal control which is different from risk based auditing. The study recommends that the senior management, the BoD/audit committee of the commercial banks and NBE have to provide the necessary support and the internal audit department has to implement the accepted international auditing standards and principles so as to have effective internal audit functions in all commercial banks.

The analysis shows that this heterogeneity increases with increasing occupancy. Some participants were able to reach lower travel time due more efficient path selection and more aggressive behavior within the crowd. Based on this observations, linear model predicting travel time with respect to the aggressiveness of pedestrian is proposed.

description: Corrosion is one main lifetime limiting degradation modes of photovoltaic (PV) modules. The process is usually gradual and it can take decades to become a factor that significantly affects performance because of the slow accumulation of moisture and acetic acid (from encapsulant degradation). In this work accelerated corrosion tests were performed on modules with Al-back surface field (BSF) and silicon heterojunction (SHJ) solar cells by immersion in water or acetic acid baths. After lamination the top encapsulant/glass were removed so that only the front size of the cells was exposed. During the tests to failure three factors were varied: acid concentration, temperature, and electrical bias. SHJ solar cells were found to be more resistant to degradation than Al-BSF cells. For all factors studied the presence of acid accelerated degradation compared to the control tests with water. Elevated temperatures accelerated the rate of degradation by several times. Application of electrical bias led to an initial drop in current, but these modules eventually outperformed the non-biased modules. Lead oxides were the primary degradation products detected, found to accumulate mostly along the printed metallization in proximity to the busbar. The accelerated corrosion test methodology is being optimized to match characteristics observed in field modules with corrosion, and can readily be applied to other solar cell, metallization, and interconnection technologies to assess their long-term durability.

description: In this paper, we study the recent 750 GeV diphoton excess in the Hill Model with vector-like fermions, in which the singlet-like Higgs boson is chosen as 750 GeV resonance and is mainly produced by the gluon fusion through vector-like top and bottom quarks. Meanwhile its diphoton decay rate is greatly enhanced by the vector-like lepton. Under the current experimental and theoretical constraints, we present the viable parameter space that fits the 750 GeV diphoton signal strength at 13 TeV LHC. We find that the heavier vector-like fermion masses are, the smaller mixing angle $θ$ is required. The mixing angle of singlet and doublet Higgs bosons is constrained within $|\sinθ| \lesssim 0.15$ in the condition of the perturbative Yukawa couplings. In the allowed parameter space, the 750 GeV diphoton cross section can be maximally enhanced to about 6 fb at 13 TeV LHC.

description: In this work, we calculate material gain for long wavelength III-nitride InN and AlInN quantum dot (QD) structures. Strain and QD inhomogeneity are included in the calculations. The study covers (800-2300 nm) wavelength range which is important in optical communications. While p-doping is shown to be efficient to increasing gain, changing QD size (especially QD radius) is more efficient to vary wavelength. The results predicted that n-doped QD structures are promises for broad band laser applications.

description: The possibility of application of crosslinking encapsulants POE and EVA with SmartWire Connection Technology in glass/glass, glass/backsheet and frontsheet/backsheet module structures was studied. The main obstacle of the modules lamination with EVA and POE encapsulants is an intensive formation of bubbles under the SmartWire electrode connecting polymer film. The reason of this is volatile organic compounds release from the encapsulants because of the chemical reactions during their crosslinking. Several approaches have been proposed to resolve this problem: 1) to find the technological window for producing modules with the POE and EVA encapsulants without bubbles; 2) to use connecting electrode films which is less inclined to accumulate the bubbles 3) to ensure smoother heating of the module stack using pin-equipped design of laminator.

description: The purpose of this research is to examine the determinant factors affecting employees' job performance at commercial bank of Ethiopia Addis Ababa city branches. This research is conducted through descriptive design by employing mixed research approach. The stratified random sampling method was employed to select respondents for the questionnaire, and Purposive sampling was also managed to select the interviewees. Descriptive statistics incorporation with qualitative analysis was used to present and analyze the collected data. The analysis result shows that the employees' job performance and the overall bank's achievement is deterred by factors related to employees' skill, commitment and ability, performance management system, training, working environment and motivational practices of the bank. Specifically, the research result shows as most of the employees' are male and young with 62.8% and 67.5% percentage distribution respectively. The employees' intention towards most of employee related factors is positive with the overall mean score value of 3.87. However, PMS of the bank is not managed in good manner since it lacks clarity, employees' involvement, supervisory support and fair measurement at different jobs. On the other hand, the training practice of the bank is good though it needs some improvements particularly in training place, time, need assessment and evaluation. With regard to working environment related factors, the result shows that as there are abundant office facilities and resources, inflexible working hours and unsafe working environment. Furthermore, the analysis result shows that as employees' intention towards the banks motivation and benefit package is weak with an overall average mean value of 1.75. Hence, the management of commercial bank of Ethiopia should periodically review its human resource, performance management system, training working environment and motivation practices in order to improve the limitations and to enhance employees' productivity and organizational achievement.

description: PV module failures can be a result of a variety of causes. They can lead to catastrophic failures, like glass breakage, or are observable as a loss in output power over time. Glass breakage of crystalline Silicon PV modules for instance is typically either a design flaw (too thin, not strong enough, incorrect specifications), a result of misuse (incorrect installations e.g. in a region of high snow loads or hail impact) or dramatic non-predictable weather events (flooding, extreme hail or storm events). Those are generally not related to the PV module production or design (for thin-film technologies this statement is not correct!). In this contribution we evaluate field observations and try to point them to production (process) related influencing factors. Based on a detailed FMEA of failures and possible production factors we prioritized the influence and weight “risk” of detection and failure. The FMEA is based on contributions from two research institutions, two module manufacturers and one manufacturer of production equipment. This interdisciplinary approach allowed extensive experience along module production and failure analyses could be considered. The processes with the highest priority numbers are followed up in terms of process variations and a detailed indoor and outdoor test study.

description: The recently started Austrian R&D project “ADVANCE! - Advanced Degradation Modelling of Photovoltaic Modules and Materials!”, a collaboration of Austrian applied science research and a module manufacturer, addresses innovative and complex statistical and data processing methods to enhance analysis and modelling of climate related degradation processes of photovoltaic modules. As a starting point, data from a previous project, that dealt with module design adaption to different outdoor climatic conditions, will be used, and enhanced by additional data derived from measurements and observations. In the first step the focus is on applying data science approaches on PV module stress testing results to achieve insight in underlying PV module degradation processes and to support manufacturing. An example for applying mixed effects modelling on power degradation data from 6-cell mini modules by means of pairwise comparison of aging actions using a base action, and one with an additional stress, is given, resulting in relative degradation values. Beside investigations on mini modules with identical BOM and different aging actions applied, variations in modules BOM are also investigated. In the next steps feature extraction from data will be continued and network structural equation models implemented. Of course, outdoor data analysis is necessary too, to understand module and system performance.

description: Back-contact solar cells are gaining terrain in the PV industry, although the lack of a standardized and low-cost interconnection method inhibits their market growth. To overcome this challenge, the three-dimensional multi-ribbon interconnection is proposed by imec as a novel interconnection concept for highly efficient back-contact cells. It is based on an interconnection fabric of encapsulant with incorporated metal ribbons that form a three-dimensional network. Module fabrication consists of a layup phase and a lamination step. In the layup step, a stack is established with the frontsheet, a front encapsulant, the cells, the interconnection fabric a glass or polymer backsheet. During the lamination step, soldering and encapsulation happen simultaneously. In previous research, the concept was tested in two four-cell modules with interdigitated back-contact (IBC) cells, both passing three times the IEC 61215 standard for thermal cycling reliability testing. In this work, these modules were tested using damp-heat and humidity-freeze tests. No significant sign of degradation was observed based on electrical characterization and electroluminescence imaging after consecutive 1000 hours of damp-heat and 50 cycles of humidity-freeze exposure.
