Umanità

description: Il taccuino analizza l’etimologia e la trasformazione storica del termine umanità. Dal latino humanitas, presunta celebrazione delle qualità umane che originariamente par indicasse gentilezza e cultura, proseguiamo sino all’accezione moderna di appartenenza alla specie cosiddetta umana.  

Critichiamo le narrazioni universaliste dell’illuminismo e del cristianesimo, mostrando come il concetto di umanità sia stato spesso usato in modo esclusivo e selettivo, creando una distinzione tra “due umanità”: una dominante, inclusiva solo di chi rispetta determinate condizioni culturali o religiose, e una marginalizzata, esclusa dalla narrazione ufficiale, ridotta a comparsa. L’arma ideologica è utilità artatamente creata per sacrificare intere popolazioni sull’altare del macabro sogno, del modello, della seducente dottrina di uguaglianza e fratellanza.  

Costruzioni religiose e politiche, dietro la retorica dell’unità, nascondono secoli di esclusione, violenza e oppressione.  

Attraverso la storia dei diritti umani, dalla Dichiarazione Universale del 1948 al contesto più ampio delle tradizioni religiose e culturali, il testo invita a superare l’ipocrisia dell’universalismo, proponendo una visione radicale dell’essere umano, centrata sull’esperienza biologica e sulla eterogeneità come vero fondamento di humanitas, vera essenza del vivere.

description: This thesis examines the application of hybrid active filter technology to large unbalanced loads such as those presented by electric railway traction systems. The thesis provides a systematic overview of possible hybrid topologies which will provide improvement over existing topologies. Several new topologies are identified in this process. The topologies are analysed to demonstrate the potential reduction in ratings of the active element achieved by the use of the hybrid topologies. A weakness is identified in the areas of signal detection and control system modelling. These areas are also addressed in the thesis and the modelling approach presented is believed to be new in this area. The modelling approach is demonstrated using one topology identified as having the lowest active element ratings. The analysis, operation and control algorithms are demonstrated using both simulation studies and experimental studies. The theoretical, simulated and experimental results show good correlation. The concept of duality is used to analyse and explain the operation of several new topologies identified as useful for harmonic isolation between two distorted buses. The use of hybrid topologies for harmonic isolation has not been seen before in the literature. These topologies are demonstrated using simulation studies.

description: Existence of minimal length is suggested in any quantum theory of gravity such as string theory, double special relativity and black hole physics. One way to impose minimal length is deforming Heisenberg algebra in phase space which is called Generalized Uncertainty Principle (GUP). In this paper, we develop statistical mechanics in GUP framework. Our method is quite general and does not need to fix the generalized coordinates and momenta. We define general transformation in phase space which transforms usual Heisenberg algebra to a deformed one. In this method, quantum gravity effects only acts on the structure of phase space and we relate these effects to the density of states. We find an interesting phenomenon in Maxwell-Boltzmann statistics which has not a classical analogy. We show that there is an upper bound for the number of excited particles in the limit of high temperature which implies to the condensation. Also we study modification of Bose-Einstein condensation and the completely degenerate gas.

description: Deploying deep convolutional neural network (CNN) models on ubiquitous Internet of Things (IoT) devices has attracted much attention from industry and academia since it greatly facilitates our lives by providing various rapid-response services. Due to the limited resources of IoT devices, cloud-assisted training of CNN models has become the mainstream. However, most existing related works suffer from a large amount of model parameter transmission and weak model robustness. To this end, this paper proposes a cloud-assisted CNN training framework with low model parameter transmission and strong model robustness. In the proposed framework, we first introduce MonoCNN, which contains only a few learnable filters, and other filters are nonlearnable. These nonlearnable filter parameters are generated according to certain rules, i.e., the filter generation function (FGF), and can be saved and reproduced by a few random seeds. Thus, the cloud server only needs to send these learnable filters and a few seeds to the IoT device. Compared to transmitting all model parameters, sending several learnable filter parameters and seeds can significantly reduce parameter transmission. Then, we investigate multiple FGFs and enable the IoT device to use the FGF to generate multiple filters and combine them into MonoCNN. Thus, MonoCNN is affected not only by the training data but also by the FGF. The rules of the FGF play a role in regularizing the MonoCNN, thereby improving its robustness. Experimental results show that compared to state-of-the-art methods, our proposed framework can reduce a large amount of model parameter transfer between the cloud server and the IoT device while improving the performance by approximately 2.2% when dealing with corrupted data.

description: Study examines the practice of nurses with members of a local adult Aboriginal community who were admitted to hospital. The grounded theory study was conducted in regional Queensland.. This dissertation provides the results of a grounded theory study undertaken in a regional area of Queensland which resulted in the development of a substantive theory of nursing practice with adult Aboriginal people who were admitted to hospital. This study is foundational both for nursing research and in developing an understanding of Aboriginal-non-Aboriginal relationships in the 20th century. There have been no previous studies identified through the literature or available databases which have attempted to explore or explain the relationships of nurses with Aboriginal people who are hospitalised. In addition, there is little evidence of any qualitative studies with urban Aboriginal people. Through the analysis of a variety of data, the research has identified a theory of nursing practice which is unique to the professional relationship between Aboriginal patients and professional nurses. In addition, the theory identifies those variables which support optimal nursing practices with Aboriginal patients and others which reduce standards of professional service. The development of the theory and the tenets of the theory have resulted in a number of significant implications for both the nursing profession and providers of health services to Aboriginal people. In this current climate of reconciliation, it is timely that professional nurses undertake a critical examination of their practices with Aboriginal people and those aspects which can redress some of the inequities perpetrated through ignorance or ethnocentricity over the last 160 years.

description: We introduce a one dimensional parity-time (PT)-symmetric nonlinear magnetic metamaterial consisted of split ring dimers having both gain and loss. When nonlinearity is absent we find a transition between an exact to a broken PT-phase; in the former the system features a two band gapped spectrum with shape determined by the gain and loss coefficients as well as the inter-unit coupling. In the presence of nonlinearity we show numerically that as a result of the gain/dissipation matching a novel type of long-lived stable discrete breathers can form below the lower branch of the band with no attenuation. In these localized modes the energy is almost equally partitioned between two adjacent split rings on the one with gain and the other one with loss.

description: We revisit the Hall effect and magnetoresistivity by incorporating the anisotropic scattering caused by apical oxygen vacancies in overdoped La-based cuprates. The theoretical calculations within the Fermi liquid picture agree well with a handful of anomalous magneto-transport data, better than the results using an isotropic scattering rate alone. In particular, we obtain the upturn of Hall coefficient $R_H$ with decreasing temperature $T$, the initial drop of $R_H$ in magnetic field $B$ in all overdoped regimes, the linear resistivity $ρ$ versus $B$ near the van Hove doping level, the temperature dependence of the magnetoresistivity ratio, and the violation of Kohler's law. These results suggest that many of the anomalous transport behaviors in overdoped La$_{2-x}$Sr$_x$CuO$_4$ could actually be understood within the Fermi liquid picture.

Molecular techniques for the identification of triploid citrus

subject: Horticultural crop improvement (incl. selection and breeding)

description: Project involves various methods of triploid identification in citrus fruit.. Seedlessness is a desirable horticultural attribute in Citrus and is positively associated with triploidy. The conventional cytological method for triploid identification is a laborious technique as it involves the preparation of foot-tips for chromosomal analysis. Isozymes and digital densitometry, however, offer the facility to distinguish triploid Citrus from large populations of seedlings both quickly and cheaply. Where there are no gene-dosage regulation effects, greater band density, reflecting increased enzyme activity, should be evident in the allozyme contributed by the diploid gamete for a heterozygous locus. To achieve this, appropriate methods of sample preparation, isozyme electrophoresis and digital densitometry were established. The isozymes of four enzymes, malate dehydrogenase, 6-phosphogluconate dehydrogenase, shikimate dehydrogenase, and phosphoglucose isomerase were investigated for band density differences between allozymes. Polyacrylamide gel electrophoresis was employed to study the isozymes of these four enzymes and band density was measured using a digital densitometer. Of the 4 enzymes investigated only allozymes for shikimate dehydrogenase exhibited consistent differences over a wide range of Citrus cultivars. Greater band density was evident in the allozyme contributed by the diploid gamete. The band density ratio between allozymes for triploid Citrus was close to 0.5, while for diploid Citrus band density ratios were close to 1.0. This effect is due to the extra protein coded by the additional gene dose and was not observed in diploids. Shikimate dehydrogenase proved to be an accurate molecular marker for distinguishing between diploid and triploid Citrus.
A semantic wiki as repository to review published palaeo-data in East Africa

description: Our research interests in palaeo-studies in East Africa remain high, partly because of the Out-of-Africa hypotheses predicting Homo sapiens origin to be situated in East Africa. Since several decades archaeologists and geoscientists explore suitable sites to answer related questions. Simultaneously, analytical methods applied to the archives improved in their sensibility or resolution over the given time. The amount of published scientific data is enormous, but has to be carefully checked on their robustness compared to modern standards. Therefore, it is necessary to compile datasets and excerpt the given data that are source of scientific interpretations (e.g., palaeoenvironment, palaeoclimate, evolution patterns, time models etc.). In addition, the names of the study sitesin East Africa are often transcribed from different languages or hold several synonyms for various reasons. Thus, we decided to use a semantic wiki to have the advantage of queryable structured data combined with the ability of web based frontend for collaborative editing of the content.

The presented application is based on Semantic Mediawiki (SMW), an extension of the famous Mediawiki software, the widely used wiki system mostly developed and maintained by the Wikimedia foundation as the software base of Wikipedia. The SMW extension allows to enter structured semantic data on wiki pages. This data can then be queried through several interfaces within the wiki and the Mediawiki API as well as an SPARQL endpoint for access from external applications. Query results can be exported in several well known formats, such as CSV, XML, JSON, and more. It is also possible to display query results directly in the wiki, using a number of provided display formats, like tables, data graphs or maps.

The presented system allows to collaboratively develop and maintain a data basis and thus implements a collaborative research environment (CRE). The data can be exported for use in scientific software packages for e.g. statistical or GIS analysis. A further outcome of the approach is a domain data model of the structured information stored in the system, which can be formalised and mapped to existing data bases to allow data integration between applications.

Details of published and unpublished archaeological and geological sites/localities in East Africa are collected in the presented wiki including their bibliographical reference. For example from sediment records, results from available sedimentological/chemical/biological proxy data (e.g., grain size, total organic carbon, stable isotopes, diatoms, ostracods, magnetic susceptibility) are copied into the database including their spatial resolution. Related dating samples (i.e., 14C, OSL, TSL) are also included with their metadata and lab-codes.

description: Uncertainty relations express limits on the extent to which the outcomes of distinct measurements on a single state can be made jointly predictable. The existence of nontrivial uncertainty relations in quantum theory is generally considered to be a way in which it entails a departure from the classical worldview. However, this perspective is undermined by the fact that there exist operational theories which exhibit nontrivial uncertainty relations but which are consistent with the classical worldview insofar as they admit of a generalized-noncontextual ontological model. This prompts the question of what aspects of uncertainty relations, if any, cannot be realized in this way and so constitute evidence of genuine nonclassicality. We here consider uncertainty relations describing the tradeoff between the predictability of a pair of binary-outcome measurements (e.g., measurements of Pauli X and Pauli Z observables in quantum theory). We show that, for a class of theories satisfying a particular symmetry property, the functional form of this predictability tradeoff is constrained by noncontextuality to be below a linear curve. Because qubit quantum theory has the relevant symmetry property, the fact that its predictability tradeoff describes a section of a circle is a violation of this noncontextual bound, and therefore constitutes an example of how the functional form of an uncertainty relation can witness contextuality. We also deduce the implications for a selected group of operational foils to quantum theory and consider the generalization to three measurements.

Alternative environments and young relocated athletes

description: Investigates the relocation of 'elite' young male athletes and the environment they need to be housed in when moved from their original home to new surroundings.. Sport for Australians can mean many different things. For some it is a favourite recreational pursuit but for a small percentage of the Australian population sport represents a way of life or a career. It has become increasingly beneficial for the skills and talent of our athletes to be utilised as a natural resource (Woodman, 1985) and to be exported overseas, thus generating an international reputation via sport for Australia. To pursue the dream of 'eliteness', many individuals may often need to relocate to reach their goals. This often means moving away from their family and home and being housed in an environment unknown to them. This research was concerned with investigating the environment that relocated athletes need to be housed in, while also identifyng the issues that arise from the process of relocating an individual from their original home environment to 'new' surroundings. Two phases were employed in the research. The first phase was to identify the elements perceived necessary when establishing a suitable relocation environment for young male athletes. The second phase explored the participants' views on the identified elements and issues. It was not the focus ofthis research to study the effect of the environment on athletic ability but to determine a suitable relocation environment for young male athletes. By achieving this, a small step may be made towards enhancing the influence of environment on the development ofathletic talent.

description: In previous papers, a cosmological model with constant-rate particle creation and vacuum term decaying linearly with the Hubble parameter was shown to lead to a good concordance when tested against precise observations: the position of the first peak in the spectrum of anisotropies of the cosmic microwave background (CMB), the Hubble diagram for supernovas of type Ia (SNe Ia), the distribution of large-scale structures (LSS) and the distance to the baryonic acoustic oscillations (BAO). That model has the same number of parameters as the spatially flat standard model and seems to alleviate some observational/theoretical tensions appearing in the later. In this letter we complement those tests with 109 gamma ray bursters (GRB), 59 of them with redshifts above $z=1.4$, which permits to extend the Hubble diagram to redshifts up to $z\approx 8$. For the calibration of the 50 GRBs with $z<1.4$ we use the 288 supernovas of the Sloan Digital Sky Survey (SDSS) project, calibrated with the MLCS2k2 fitter, less model-dependent than other samples like Union2. Our results show a good concordance with the previous tests and, again, less tensions between SNe Ia and GRB best fits as compared to the standard model.

description: We re-investigate the possibility of X(3872) as a $D\bar{D}^*$ molecule with $J^{PC}=1^{++}$ within the framework of both the one-pion-exchange (OPE) model and the one-boson-exchange (OBE) model. After careful treatment of the S-D wave mixing, the mass difference between the neutral and charged $D(D^*)$ mesons and the coupling of the $D(D^*)$ pair to $D^*\bar{D}^*$, a loosely bound molecular state X(3872) emerges quite naturally with large isospin violation in its flavor wave function. For example, the isovector component is 26.24% if the binding energy is 0.30 MeV, where the isospin breaking effect is amplified by the tiny binding energy. After taking into account the phase space difference and assuming the $3π$ and $2π$ come from a virtual omega and rho meson respectively, we obtain the ratio of these two hidden-charm decay modes: $\mathcal{B}(X(3872)\rightarrow π^+π^-π^0 J/ψ)/\mathcal{B}(X(3872)\rightarrow π^+π^- J/ψ)=0.42$ for the binding energy being 0.3 MeV, which is consistent with the experimental value.

description: The ground vector $B_{c}^{\ast}$ meson has not yet been experimentally discovered until now. Besides the dominant electromagnetic decays, nonleptonic weak decays provide another choice to search for the mysterious $B_{c}^{\ast}$ mesons. Inspired by the potential prospects of $B_{c}^{\ast}$ mesons in future high-luminosity colliders, nonleptonic $B_{c}^{\ast}$ weak decays induced by bottom and charm quark decays are studied within the SM by using a naive factorization approach. It is found that for $B_{c}^{\ast}$ ${\to}$ $B_{s,d}π$, $B_{s,d}^{\ast}π$, $B_{s,d}ρ$, $B_{s}K$, $B_{s}^{\ast}K$, $B_{s}K^{\ast}$, $η_{c}(1S,2S)π$, $η_{c}(1S,2S)ρ$ and $ψ(1S,2S)π$ decays, a few hundred and even thousand of events might be observable in CEPC, FCC-ee and LHCb@HL-LHC experiments.

description: High entropy materials (HEMs) are of great interest for their mechanical, chemical and electronic properties. In this paper we analyse (TaNbHfTiZr)C, a carbide type of HEM, both in crystalline and amorphous phases, using density functional theory (DFT). We find that the relaxed lattice volume of the amorphous phase is larger, while its bulk modulus is lower, than that of its crystalline counterpart. Both phases are metallic with all the transition metals contributing similarly to the density of states (DOS) close to the Fermi level, with Ti and Nb giving the proportionally largest contribution of states. We confirm that despite its great structural complexity, 2x2x2 supercells are large enough for reliable simulation of the presented mechanical and electronic properties by DFT.

For a point set in this collection, we characterise minimality of an associated dynamical system by almost repetitivity of the point set. We also provide linear versions of almost repetitivity which lead to uniquely ergodic systems. Apart from linearly repetitive point sets, examples are given by periodic point sets with almost periodic modulations, and by point sets derived from primitive substitution tilings of finite local complexity with respect to the Euclidean group with dense tile orientations.

description: We study the motion of a superfluid vortex in condensates having different background density profiles, ranging from parabolic to uniform. The resulting effective point-vortex model for a generic power-law potential $\propto r^k$ can be experimentally realized with recent advances in optical-trapping techniques. Our analysis encompasses both empty-core and filled-core vortices. In the latter case, the vortex acquires a mass due to the presence of distinguishable atoms located in its core. The axisymmetry allows us to reduce the coupled dynamical equations of motion to a single radial equation with an effective potential $V_{\rm eff}$. In many cases, $V_{\rm eff}$ has a single minimum, where the vortex precesses uniformly. The dynamics of the vortex and the localized massive core arises from the dependence of the energy on the radial position of the vortex and from the $r^k$ trap potential. We find that a positive vortex with small mass orbits in the positive direction, but the sense of precession can reverse as the core mass increases. Early experiments and theoretical studies on two-component vortices found some qualitatively similar behavior.

description: The 10-electron generalized relativistic effective core potential and the corresponding correlation spin-orbital basis sets are generated for the Ra atom and the relativistic coupled cluster calculations for the RaO molecule are performed. The main goal of the study is to evaluate the P,T-odd parameter X characterized by the molecular electronic structure and corresponding to a "volume effect" in the interaction of the ^{225}Ra nucleus Schiff moment with electronic shells of RaO. Our final result for X(^{225}RaO) is -7532 which is surprisingly close to that in ^{205}TlF but has different sign. The obtained results are discussed and the quality of the calculations is analyzed. The value is of interest for a proposed experiment on RaO [PRA 77, 024501 (2008)] due to a very large expected Schiff moment of the ^{225}Ra nucleus.

description: The optimal shapes attained by contractile cells on adhesive substrates are determined by the interplay between intracellular forces and adhesion with the extracellular matrix. We model the cell as a contractile film bounded by an elastic cortex and connected to the substrate via elastic links. When the adhesion sites are continuously distributed, optimal cell shape is constrained by the adhesion geometry, with a spread area sensitively dependent on the substrate stiffness and contractile tension. For discrete adhesion sites, equilibrium cell shape is convex at weak contractility, while developing local concavities at intermediate values of contractility. Increasing contractility beyond a critical value, controlled by mechanical and geometrical properties of adhesion, cell boundary undergoes a discontinuous transition to a star-shaped configuration with cusps and protrusions, accompanied by a region of bistability and hysteresis.

description: Poor workplace relations are an issue of concern in many workplaces and this phenomenon is not restricted to the nursing profession. The issue of workplace violence in nursing is well documented and there are an increasing number of studies which have investigated the notion of horizontal violence amongst graduate nurses. The impact that poor workplace relations has on the development of a professional identity by nursing students in the off-campus clinical setting is significant in light of the current global shortage of nurses. There is a dearth of knowledge in understanding how Australian undergraduate nursing students experience the off-campus clinical setting and subsequently develop a professional identity as a nurse. Therefore the aim of this study was to discover and describe the phenomena in order to develop a substantive theory that explains the experiences of the under-graduate nursing students in a regional setting. Constructivist grounded theory methods were utilised in the conduct of the study. A sample of 29 participants was recruited permitting the formulation of a substantive theory regarding the development of a professional identity in nursing students. This substantive theory contributes knowledge relevant to the undergraduate nursing students, nurse educators, nursing workforce planners, and the tertiary educational institutions offering nursing. This is achieved through discovering, describing and explaining the phenomenon of anxiety which the nursing students experience as a result of the interrelationship and interactions of tradition bearing, staff and student performance. These interactions intersect to form expectations of where the student fits within the hierarchy of the facility and the nursing profession in general. An understanding of the issues associated with tradition bearing, staff performance, and student performance and the impact that the interaction of these conditions has upon the students developing professional identity as a nurse is necessary to allow for the implementation of corrective strategies.

description: We report a highly unusual angular variation of the upper critical field (H_c2) in epitaxial superlattices CeCoIn_5(n)/YbCoIn_5(5), formed by alternating layers of n and a 5 unit-cell thick heavy-fermion superconductor CeCoIn_5 with a strong Pauli effect and normal metal YbCoIn_5, respectively. For the n=3 superlattice, H_{c2}(θ) changes smoothly as a function of the field angle θ. However, close to the superconducting transition temperature, H_{c2}(θ) exhibits a cusp near the parallel field (θ=0 deg). This cusp behavior disappears for n=4 and 5 superlattices. This sudden disappearance suggests the relative dominance of the orbital depairing effect in the n=3 superlattice, which may be due to the suppression of the Pauli effect in a system with local inversion symmetry breaking. Taking into account the temperature dependence of H_{c2}(θ) as well, our results suggest that some exotic superconducting states, including a helical superconducting state, might be realized at high magnetic fields.

description: "This thesis describes the development of an expert system, EXFIT designed to bridge the gap between the scientist and the coach and facilitate the provision of scientific information in a systematic and coherent fashion in a report to the coach." -- abstract. One of the problems in the physiological assessment of an athlete is poor communication of the results of the physiological tests to the coach. This thesis describes the development of an expert system, EXFIT designed to bridge the gap between the scientist and the coach and facilitate the provision of scientific information in a systematic and coherent fashion in a report to the coach. The expert system provides generalized recommendations which the coach utilizes in developing specific training schedules suited to the particular athlete to enhance performance. The recommendations are based on a series of physiological analyses of the athlete. The analyses available in EXFIT are: anaerobic power (peak and total), aerobic power, onset of blood lactate accumulation, maximum blood lactate, blood, muscle structure (fibre type), metabolic status of muscle - aerobic capacity and anaerobic capacity. For two of these analyses, namely the anaerobic power (peak and total) and the aerobic power, provision has been made to allow for both manual and automatic acquisition of the data from the tests for which the data acquisition system was developed as part of this project. The results of the test equipment not presently interfaced to the computer are collected and entered manually. The implementation of the expert system is described with emphasis placed on recognition of the internal structure of theknowledge, independence from a particular expert system shell and the design for future expansion and maintenance. EXFIT has been split into the four separate modules of user interface, data, information and knowledge. The data and information have been normalized and stored using the knowledge dictionary concept. The design for maintenance was tested by writing a program that allows the domain expert to modify or add to the data and information of EXFIT without the requirement for a knowledge engineer.

description: Sampling is ubiquitous in machine learning methodologies. Due to the growth of large datasets and model complexity, we want to learn and adapt the sampling process while training a representation. Towards achieving this grand goal, a variety of sampling techniques have been proposed. However, most of them either use a fixed sampling scheme or adjust the sampling scheme based on simple heuristics. They cannot choose the best sample for model training in different stages. Inspired by "Think, Fast and Slow" (System 1 and System 2) in cognitive science, we propose a reward-guided sampling strategy called Adaptive Sample with Reward (ASR) to tackle this challenge. To the best of our knowledge, this is the first work utilizing reinforcement learning (RL) to address the sampling problem in representation learning. Our approach optimally adjusts the sampling process to achieve optimal performance. We explore geographical relationships among samples by distance-based sampling to maximize overall cumulative reward. We apply ASR to the long-standing sampling problems in similarity-based loss functions. Empirical results in information retrieval and clustering demonstrate ASR's superb performance across different datasets. We also discuss an engrossing phenomenon which we name as "ASR gravity well" in experiments.

description: Project describes experiments done to study the effects of some variants in the austempering process on mechanical properties, especially fatigue of ADI. The calculation of the stress intensity factor is also looked into.. Some factories in Indonesia plan to produce Austempered Ductile Iron (ADI), because this material offers some advantages over other cast irons, such as having excellent fatigue properties and also being cheaper than steel. This thesis describes some experiments done to study the effect of some variants in the austempering process on mechanical properties, especially fatigue of ADI. In particular the effect of holding time on fatigue properties of ADI were studied, and an attempt was made to answer the question "Can the stress concentration factor theory proposed by Kubicki be applied to ductile cast iron and ADI?" This stress concentration model enables quantification of the influence of both matrix yield strength and size ofinclusions on the endurance limit of inhomogeneous material. Initially some laboratory experiments were done such as tensile tests, hardness tests and fatigue tests. The tensile and hardness data are plotted on a histogram diagram while the fatigue results are plotted on an S-N curve. The results of the calculations were compared withthe fatigue test results. The conclusions are: Increasing holding time can decrease the mechanical properties of ADI; Comparing Kubicki's theoretical result with the fatigue test result shows quite strong agreement.
