A Comparative Study of the Use of Reward Systems between Production and Service Sectors
Creators: name: Amha, Dawit
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This study is about reward system, which essentially is a steering instrument available to maintain the organizational efficiency and productivity and which also have the purpose of motivating the employees to act in the best interest of the organization as well as to reach organizational goals. The purpose with this study was to see how companies in different sectors make use of a reward system in order to increase their effectiveness and efficiency. The aim was also to see to what extent organizations are linking the organizational goals with the individual goals that occur within an organization. A comparison between the sectors has done in order to observe similarities as well as differences. As groundwork of this thesis theories regarding motivation and effectiveness and efficiency were used. The research question was based on the purpose with this study and stated as follows: "In what way are organizations using a reward system to motivate the employees to work in the best interest of the organization and reach organizational goals?" In order to answer the research question I have conducted a qualitative study. I have made two interviews with different companies within two different sectors, a total of four interviews. The sectors that I have chosen to focus on were the production sector and the service sector. The interviews were all face to face meetings in Addis Ababa. The empirical findings have then been tried to be analyzed by linking them to the theories used in the theoretical framework. The main conclusions I have made is that all companies are focusing primarily on profitability and results when rewarding. Within all sectors, the companies have found very difficult to link individual goals to organizational goals in the organization. It is only Ethiopian Electric Power Corporation (EEPCO) that already laid the ground for linking individual goals to organizational goals though it is not yet started implementing the system. Based on my finding the production sector is working more satisfactorily concerning employees' job satisfaction and motivation. Further I could conclude that the less developed reward system an organization has and considers it to be a steering instrument the less thoroughly developed will the groundwork for it be and vice versa. Some similarities that I could see within the two sectors were that they all are using monetary and non monetary rewards (financial and non financial rewards) and that the rewards are being given to both individuals to teams though differ in extent.

"Determinants of Non-Performing Loans: Evidence from Commercial Banks in Ethiopia"
Creators: name: Asfawesen, Mekdes
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This study examined the bank-specific and macro-economic determinants of Non-performing loans (NPLs) of Ethiopian commercial banks. The study adopted a quantitative research approach. The study uses data collected from the National Bank of Ethiopia, Central Statistical Agency and financial statement of nine commercial banks. Data covers the period from 2006-2016. Descriptive and multiple regression analysis employed to analyze the unbalanced panel data. Findings of the study show that return on equity and capital adequacy have negative and significant impact on NPLs. Whereas, loan loss provision and loan to deposit have positive significant relationship with NPLs. The finding of this study is important since once identifying the determinants of NPLs might enable management body to make appropriate lending policies that prevent the occurrence of NPLs. The study recommended as bank managers better emphasize the management of current assets specially loans. Furthermore, preferable for commercial banks to concentrate or diversify their credit portfolio by calculating risk relative to its return in order to increase return on equity and to reduce the level of nonperforming loans. Also the study suggest for future researcher to validate the consistency of the result and provide additional results by including other variables like priority sector loan, monitory policy and sensitive sector's loan. Key words: Nonperforming loans, bank specific factors, macroeconomic factors

description: We compare the bar fractions as a function of the Hubble sequence by adopting different methods for the same sample (Lee et al.2019). For the same sample with z < 0.01 from SDSS, the visual inspection, ellipse fitting method, and the Fourier analysis detect 63%, 48%, and 36% of barred galaxies. The fractions largely get different as a function of the Hubble sequence. The ellipse fitting method obtains the increasing bar fraction towards late-type spirals, whereas the Fourier analysis releases the opposite tendency, increasing the bar fraction towards early-type spirals. It is because the ellipse fitting method generally misses barred galaxies when the bulge dilutes the ellipticity of the whole galaxy. The bar strength is also differently affected by the algorithm to measure it: the Fourier analysis increases the bar strength when a galaxy has a large bulge. We develop a new method to classify barred galaxies based on their potential map by analyzing the butterfly pattern (Lee et al. 2020). This method detects 53% of barred galaxies including SBs and SABs, which are consistent with the visual inspection by an accuracy of 87%. Finally, we classify barred galaxies into fast, medium, and slow bars by estimating the frequency curves and using the bar pattern speed (Lee et al. 2022). It could provide information for the evolutionary stage of the bar, supporting little evolution of the bar length and strength during the bar evolution.

description: Recently, we extracted the strong coupling, $α_s(m_τ^2)$, from the revised ALEPH data for non-strange hadronic tau decays. Our analysis is based on a method previously used for the determination of the strong coupling from OPAL data. In our strategy, we employ different moments of the spectral functions both with and without pinching, including Duality Violations, in order to obtain fully self-consistent analyses that do not rely on untested assumptions (such as the smallness of higher dimension contributions in the OPE). Here we discuss the $α_s$ values obtained from the ALEPH and the OPAL data, the robustness of the analysis, as well as non-perturbative contributions from DVs and the OPE. We show that, although the $α_s$ determination is sound, non-perturbative effects limit the accuracy with which one can extract the strong coupling from tau decay data. Finally, we discuss the compatibility of the data sets and the possibility of a combined analysis.

description: In this paper, we aimed at assessing the best conditions for the isolation of actinobacteria from old potato samples. A set of media and pretreatments were tested. The optimal were chosen for the isolation of actinobacteria from potatoes from Peru, Chile and Argentina. Isolates were tested on the presence of thaxtomin phytotoxin by amplification of the respective gene. Phylogenetic position of strains was compared with their geographical origin, pathogenic potential and existence of common scab (CS) symptoms on potato sample. We demonstrated that RNAlater can be successfully used for the long-term preservation of potato peel for subsequent isolation of actinobacteria on R2A medium. Many streptomycetes were thaxtomin-positive, though they are distantly-related to described pathogens causing CS. Genus Nocardia was first reported to be thaxtomin-positive. Potentially pathogenic strains were isolated not only from infected potato but also from those lacking CS symptoms. Some strains from scabby potatoes were thaxtomin-negative.
Uncertain Loading and Quantifying Maximum Energy Concentration within Composite Structures

description: We introduce a systematic method for identifying the worst case load among all boundary loads of fixed energy. Here the worst case load is defined to be the one that delivers the largest fraction of input energy to a prescribed subdomain of interest. The worst case load is identified with the first eigenfunction of a suitably defined eigenvalue problem. The first eigenvalue for this problem is the maximum fraction of boundary energy that can be delivered to the subdomain. We compute worst case boundary loads and associated energy contained inside a prescribed subdomain through the numerical solution of the eigenvalue problem. We apply this computational method to bound the worst case load associated with an ensemble of random boundary loads given by a second order random process. Several examples are carried out on heterogeneous structures to illustrate the method.
Conditions for Bar Formation in Disk Galaxies with Halo and Bulge

Year: 2023

description: While bars are common in disk galaxies, their formation conditions are not well understood. We use N-body simulations to study the formation and evolution of a bar in isolated galaxies consisting of a stellar disk, a classical bulge, and a dark halo. We consider 24 galaxy models that are similar to the Milky Way but differ in the mass and compactness of the classical bulge and halo concentration. We find that the bar formation requires (QT,min /1.2)2 + (CMC/0.05)2 < 1, where QT,min and CMC refer to the minimum value of the Toomre stability parameter and the central mass concentration, respectively. Bars tend to be stronger and longer, and to rotate more slowly, in galaxies with a less massive and less compact bulge and halo. All bars formed in our models correspond to slow bars. A model with the bulge mass of ∼10%–20% of the disk under a concentrated halo produces a bar similar to that of the Milky Way. We discuss our findings in relation to other bar formation criteria suggested by previo

description: The attention for the replacement of peat in growing substrates is increasing due to its environmental and economic advantages. The aim of the present work was to evaluate the impact of peat substitution by new type olive mill pomace and its compost on the vegetative activity of potted olive trees. A new type of humid pomace (hP) derived from an innovative two phase extraction system and its derived compost (C-hP) are used as total or partial (50% vol/vol) replacement of peat in olive growing substrate. The main chemical characteristics (moisture, water extractable organic carbon, total nitrogen, C/N ratio and electrical conductivity) of the hP and C-hP were measured. In order to evaluate the effects of the peat substitution on the plants vegetative activity, measurements of mortality, plant height, leaf net photosynthesis and plant growth (through final destructive measurements) were carried out. The use of hP resulted in a significant increase of the salinity of the substrate. The water extractable organic carbon concentration was higher in all substrates where peat was ewplaced and in particular when C-hP was used. The total replacement of peat with hP caused 100% mortality of the plants while C-hP can substitute peat up to 50% without causing a significative reduction of the final plant growth.

description: We present digital tables for the radiative terms that appear in the energy and momentum equations used to simulate the accretion onto supermassive black holes (SMBHs) in the center of galaxies. Cooling and heating rates and radiative accelerations are calculated with two different Spectral Energy Distributions (SEDs). One SED is composed of an accretion disk + [X-ray]-powerlaw, while the other is made of an accretion disk + [Corona]-bremsstrahlung with $T_X=1.16 \times 10^8$ K, where precomputed conditions of adiabatic expansion are included. Quantification of different physical mechanisms at operation are presented, showing discrepancies and similarities between both SEDs in different ranges of fundamental physical parameters (i.e., ionization parameter, density, and temperature). With the recent discovery of outflows originating at sub-parsec scales, these tables may provide a useful tool to model gas accretion processes onto a SMBH.

description: The RXTE observed four outbursts of the accreting X-ray binary transient source, GX 304-1 in 2010 and 2011. We present results of detailed 3-100 keV spectral analysis of 69 separate observations, and report a positive correlation between cyclotron line parameters, as well as other spectral parameters, with power law flux. The cyclotron line energy, width and depth versus flux, and thus luminosity, correlations show a flattening of the relationships with increasing luminosity, which are well described by quasi-spherical or disk accretion that yield the surface magnetic field to be ~60 keV. Since HEXTE cluster A was fixed aligned with the PCA field of view and cluster B was fixed viewing a background region 1.5 degrees off of the source direction during these observations near the end of the RXTE mission, the cluster A background was estimated from cluster B events using HEXTEBACKEST. This made possible the detection of the ~55 keV cyclotron line and an accurate measurement of the continuum. Correlations of all spectral parameters with the primary 2-10 keV power law flux reveal it to be the primary driver of the spectral shape. The accretion is found to be in the collisionless shock braking regime.

description: In the system of comprehensive assessment of feed nutritional value, protein plays a special role. With the correct selection of proteolytic enzymes in the diet and with appropriate conditions (pH, temperature, duration and quantity of enzymes), most feed proteins can be degraded to preferred degree in the body: either partially, limited by proteolysis, or deep and complete – to individual amino acids, which is accompanied by an increase in animal productivity. The objective was to study the efficiency of using the exogenous enzyme Sibenza DP 100 in the diet on productivity and development of broilers chickens’ internal organs. The experimental part of the work was carried out under the industrial conditions of private limited company 'LISKoBroiler' on Ross 308 broiler chickens. When the proteolytic enzyme was added to the birds’ diet without decreasing the nutritional value of crude protein and digestible aminoacids, higher values of the average daily gain were observed among all experimental groups compared to the control group, while reducing feed output per 1 kg of gain. While reducing the nutritional diet value in accordance with the matrix by 2.5% for crude protein and digestible amino acids and with the addition of the Sibenza DP 100 enzyme (500 g t-1), growing broilers was characterized by a slight lag in live weight compared to the control group, but with the most effective consumption feed per 1 kg of gain. The abovementioned system for the proteolytic enzyme use had the most positive effect on the morphological structure of the pancreas of broiler chickens.

description: We studied the physical parameters of a sample comprising of all Spitzer/IRS public spectra of Seyfert galaxies in the mid-infrared (5.2-38$μ$m range) under the active galactic nuclei (AGN) unified model. We compare the observed spectra with $\sim10^6$ CLUMPY model spectral energy distributions, which consider a torus composed of dusty clouds. We find a slight difference in the distribution of line-of-sight inclination angle, $i$, requiring larger angles for Seyfert 2 (Sy2) and a broader distribution for Seyfert 1 (Sy1). We found small differences in the torus angular width, $σ$, indicating that Sy1 may host a slightly narrower torus than Sy2. The torus thickness, together with the bolometric luminosities derived, suggest a very compact torus up to $\sim$6 pc from the central AGN. The number of clouds along the equatorial plane, $N$, as well the index of the radial profile, $q$, are nearly the same for both types. These results imply that the torus cloud distribution is nearly the same for type 1 and type 2 objects. The torus mass is almost the same for both types of activity, with values in the range of $M_{tor}\sim$10$^{4}-$10$^{7}\rm M_{\odot}$. The main difference appears to be related to the clouds' intrinsic properties: type 2 sources present higher optical depths $τ_V$. The results presented here reinforce the suggestion that the classification of a galaxy may depend also on the intrinsic properties of the torus clouds rather than simply on their inclination. This is in contradiction with the simple geometric idea of the unification model.

description: Kombucha – a spontaneously fermented tea beverage, produced by SCOBY (a symbiont of bacteria and yeasts), has become popular in recent years. Its functional properties and features for industrial production and treatment remain largely unknown, however. Our aim of using additional yeast cultures during the primary fermentation was to modify and ultimately improve the sensory properties of the kombucha beverage. During five fermentation experiments the total viable count (TVC) of microbes was determined both in Kombucha and SCOBY samples. The first four fermentation experiments were conducted to stabilize the growth of SCOBYs that were initially of different origin. The last (5th) fermentation contained the simultaneous inoculation of three different active S. cerevisiae cultures into the sweetened black tea together with the SCOBY and was followed by a sensory analysis. Two samples remained as control samples without additional yeast starter culture. The yeast starter cultures affected the microbial counts of Kombucha, but the effect on the microbial count of SCOBY was not statistically significant (p >0.05). The Kombucha containing wine yeast culture had the lowest sensory quality, while Kombucha containing brewer's yeast had the most pleasant flavour and aroma. In conclusion, the simultaneous fermentation with commercial yeast cultures had a minor effect on the microbial counts in SCOBY when compared to the fermentation time, but all added cultures clearly modified the taste and aroma properties of the Kombucha drinks.

description: Maturity models to assess research data management (RDM) in engineering research projects. For this purpose, individual maturity models are developed for identified process areas that include RDM activities based on their occurrence in the research process. These enable a qualitative assessment on discrete maturity levels, from an initial state to an optimizing final state. Researchers are primarily responsible for meeting the requirements of research data management, which is why the maturity models are aimed directly at the researchers in the research project and enable self-assessment. The individual maturity models follow a defined maturity structure with five maturity levels from an undefined, reactive stage to continuous improvement and active participation in the research community. This work thus shows the structural framework of the maturity models to be developed and offers an implementation of research data management in the research process.

Essays on International Finance and Economic Growth in Africa
Creators: name: Addis, Yimer
Publisher: name: National Academic Digital Repository of Ethiopia

description: This study attempts to estimate the volume of capital flight from Ethiopia and its determinants, focusing on economic, institutional, and political determinants. Capital flight is estimated at US$ 31 billion over the 1970–2012 period. On average, the country lost around half a billion dollars annually under the 'Derg' regime. This amount nearly doubled to US$ 1 billion per annum during the EPRDF regime. The empirical evidence suggests that macroeconomic instability, the degree of financial market deepening, exports, interest rate differentials, political instability, corruption, and debt-creating flows are the most important determinants of capital flight from Ethiopia. The political environment is also found to be crucial. Generally, capital flight was high before violent regime changes and low in the subsequent periods, when regimes were in the process of establishing a firmer grip on power; after this point, however, capital flight began to rise significantly again. The historical analysis points to potential causality running from political factors to capital flight. A strong improvement in economic and political governance will be key to abating the problems of capital flight in Ethiopia.

description: The Coulomb and Higgs branches of certain 3d N=4 gauge theories can be understood as closures of nilpotent orbits. Recently, a new theorem by Namikawa suggests that this is the simplest possible case, thus giving this class a special role. In this note we use branes to reproduce the mathematical work by Kraft and Procesi. It studies the classification of all nilpotent orbits for classical groups and it characterizes an inclusion relation via minimal singularities. We show how these minimal singularities arise naturally in the Type IIB superstring embedding of the 3d A-type theories. The Higgs mechanism can be used to remove the minimal singularity, corresponding to a transition in the brane configuration that induces a new effective 3d theory. This reproduces the Kraft-Procesi results, endowing the family of gauge theories with a new underlying structure. We provide an efficient procedure for computing such brane transitions.

description: Optimization of product performance repetitively introduces the need to make products adaptive in a more general sense. This more general idea is often captured under the term 'self-configuration'. Despite the importance of such capability, research work on this feature appears isolated by technical domains. It is not easy to tell quickly whether the approaches chosen in different technological domains introduce new ideas or whether the differences just reflect domain idiosyncrasies. For the sake of easy identification of key differences between systems with self-configuring capabilities, I will explore higher level concepts for understanding self-configuration, such as the Ω-units, in order to provide theoretical instruments for connecting different areas of technology and research.

description: We prove the renormalizability to all orders of a refined Gribov-Zwanziger type action in linear covariant gauges in four-dimensional Euclidean space. In this model, the Gribov copies are taken into account by requiring that the Faddeev-Popov operator is positive definite with respect to the transverse component of the gauge field, a procedure which turns out to be analogous to the restriction to the Gribov region in the Landau gauge. The model studied here can be regarded as the first approximation of a more general nonperturbative BRST invariant formulation of the refined Gribov-Zwanziger action in linear covariant gauges obtained recently in [Phys. Rev. D 92, no. 4, 045039 (2015) and arXiv:1605.02610 [hep-th]]. A key ingredient of the set up worked out in [Phys. Rev. D 92, no. 4, 045039 (2015) and arXiv:1605.02610 [hep-th]] is the introduction of a gauge invariant field configuration $\mathbf{A}_μ$ which can be expressed as an infinite non-local series in the starting gauge field $A_μ$. In the present case, we consider the approximation in which only the first term of the series representing $\mathbf{A}_μ$ is considered, corresponding to a pure transverse gauge field. The all order renormalizability of the resulting action gives thus a strong evidence of the renormalizability of the aforementioned more general nonperturbative BRST invariant formulation of the Gribov horizon in linear covariant gauges.

description: In 2015, using an innovative technique, Carando, Defant and Sevilla-Peris succeeded in proving a Bohnenblust--Hille type inequality with constants of polynomial growth in $m$ for a certain family of complex $m$-homogeneous polynomials. In the present paper, using a completely different approach, we prove that the constants of this inequality are uniformly bounded irrespectively of the value of $m$.

description: This chapter analyzes FDI's impact on economic growth in SSA countries for which relevant macroeconomic data is available for the period 2001-15. To achieve this, it develops a dynamic system GMM model to capture FDI's impact on economic growth. It chooses the dynamic panel system GMM because of its superiority over other models in that it takes care of endogeneity problems and alleviates possible biases in the estimation. Besides, it also provides a solution to the problem associated with time-invariant individual heterogeneity, among others. The study includes 43 SSA countries for which data is available. The countries are categorized into 'resource-rich' and 'resource-poor' using data on their natural resource endowments and other important factors. The study found that there was no meaningful difference in the growth of per capita GDP and in these countries' ability to attract FDI inflows based on their resource endowments. These findings indicate that FDI had a negative and statistically significant effect on the per capita GDP growth rate in SSA countries in the study period. However, the own lagged value of the growth rate of per capita GDP and gross capital formation, which is used as a proxy for domestic investments and exports, had positive and statistically significant effects on the growth rate of per capita incomes. Though FDI is touted as a catalyst for growth, the empirical findings of this study do not support this claim in SSA. The study provides an explanation for the possible reasons for this divergence from the expected positive effects. It is clear that FDI is not a panacea for the economic malaise in the region and is not contributing to the betterment of lives and welfare. Hence, it is time for SSA governments and policymakers to find out where the problem lies and align policies in a way that make FDI have a more meaningful positive contribution in dragging millions of people out of poverty.

description: Purpose: The purpose of this paper is to analyze the results of a survey that aims to explore and identify the thread between strategic management practices of food processing companies in Addis Ababa and their corporate entrepreneurship intensity. Design\methodology: The research followed deductive approach, survey as a strategy, a crosssectional time horizon and questionnaire as data collection instrument. It also employed factor analysis (explanatory and confirmatory factor analysis) to analyze the data. Both primary and secondary data were used to gather data. Primary data were used for data analysis while the secondary sources of data included extensive review of literature. Findings: Major findings revealed that most of strategic management practice component (i.e. locus of planning, planning horizon, strategic control and planning flexibility) has positive impact on core corporate entrepreneurship dimensions (i.e. innovativeness, proactiveness and risk taking) whereas some SM dimension (i.e. financial control) has negative impact on CE dimensions. Research limitation: The research is temporally and contextually limited to food processing sub sector specifically in Addis Ababa city only which might limit its generalizability into other industries, sectors, small, medium, and large-scale business organizations and other cities and country level as a whole. Originality/value: As far as the researcher's knowledge is concerned, the absence of similar empirical studies specifically on the relationship between a firm's strategic management practices and its corporate entrepreneurial intensity in Ethiopian context also motivated the researcher to put his own contribution since Ethiopian manufacturing sector in not yet well strong as developed countries and need empirical study on this area. Key words: Strategic management, corporate entrepreneurship intensity, food processing firms Paper type: Research paper

description: We consider the mechanism of photophoretic transport in protoplanetary disks that are optically thick to radiation. Here, photophoresis is not caused by the central star but by temperature fluctuations that subject suspended solid particles, including chondrules, to non-isotropic thermal radiation within the disk. These short-lived temperature fluctuations can explain time-of-flight size sorting and general number density enhancements. The same mechanism will also lead to velocity fluctuations of dust aggregates beyond $100\,\mathrm{m\,s^{-1}}$ for mm-sized particles in protoplanetary disks. Applying this in future research will change our understanding of the early phases of collisional dust evolution and aggregate growth as particles cross the bouncing barrier and as mass transfer rates are altered.

description: We prove that a certain binary linear code associated with the incidence matrix of a quasi-symmetric 2-(37,9,8) design with intersection numbers 1 and 3 must be contained in an extremal doubly even self-dual code of length 40. Using the classification of extremal doubly even self-dual codes of length 40, we show that a quasi-symmetric 2-(37,9,8) design with intersection numbers 1 and 3 does not exist.

description: We show that a class of solutions of minimal supergravity in five dimensions is given by lifts of three--dimensional Einstein--Weyl structures of hyper-CR type. We characterise this class as most general near--horizon limits of supersymmetric solutions to the five--dimensional theory. In particular, we deduce that a compact spatial section of a horizon can only be a Berger sphere, a product metric on $S^1\times S^2$ or a flat three-torus. We then consider the problem of reconstructing all supersymmetric solutions from a given near--horizon geometry. By exploiting the ellipticity of the linearised field equations we demonstrate that the moduli space of transverse infinitesimal deformations of a near--horizon geometry is finite--dimensional.

description: This study designed to indicate factors affecting consumers shoe preference: domestic versus imported leather shoes. Specifically, to indicate how consumers evaluated both domestic and imported leather shoes interms of product quality, style and price, to examine to what extent these factors influenced the consumers' shoe choice and to look whether there was difference or not between the age groups regarding their preference in Addis Ketema sub-city shoe market. In order to achieve its objectives the study gathered data from 180 leather shoe consumers in Addis Ketema shoe market through open and close ended questionnaires. The data were analyzed through help of statistical package for social science and micro soft excel software. The findings revealed that the imported leather shoe were superior in comfortability, fashionability and range of variety. But, Domestic leather shoes had competitive advantage interms of durability and price. The study also indicated that quality, style, price, friends and culture as the major factors influenced the consumers' shoe preference. In addition, the result of the study discovered that there is difference in preference depending on consumers' age groups.

description: In this Letter, we report the observational constraints on the Hu-Sawicki $f(R)$ theory derived from weak lensing peak abundances, which are closely related to the mass function of massive halos. In comparison with studies using optical or x-ray clusters of galaxies, weak lensing peak analyses have the advantages of not relying on mass-baryonic observable calibrations. With observations from the Canada-France-Hawaii-Telescope Lensing Survey, our peak analyses give rise to a tight constraint on the model parameter $|f_{R0}|$ for $n=1$. The $95\%$ CL limit is $\log_{10}|f_{R0}| < -4.82$ given WMAP9 priors on $(Ω_{\rm m}, A_{\rm s})$. With Planck15 priors, the corresponding result is $\log_{10}|f_{R0}| < -5.16$.

description: A combined experimental and numerical study on the variation of the elastic properties of defective single-crystal diamond is presented for the first time, by comparing nano-indentation measurements on MeV-ion-implanted samples with multi-scale modeling consisting of both ab initio atomistic calculations and meso-scale Finite Element Method (FEM) simulations. It is found that by locally introducing defects in the 2x10^18 - 5x10^21 cm-3 density range, a significant reduction of, as well as of density, can be induced in the diamond crystal structure without incurring in the graphitization of the material. Ab initio atomistic simulations confirm the experimental findings with a good degree of confidence. FEM simulations are further employed to verify the consistency of measured deformations with a stiffness reduction, and to derive strain and stress levels in the implanted region. Combining these experimental and numerical results, we also provide insight into the mechanism responsible for the depth dependence of the graphitization threshold in diamond. This work prospects the possibility of achieving accurate tunability of the mechanical properties of single-crystal diamond through defect engineering, with significant technological applications, i.e. the fabrication and control of the resonant frequency of diamond-based micromechanical resonators.
