Bayes Estimation of the Reliability Function of Pareto Distribution Under Three Different Loss Functions
Authors: Shukla Gaurav , Chandra Umesh , Kumar Vinod
Published: February 2023

In this paper, we have proposed Bayes estimators of shape parameter of Pareto distribution as well as reliability function under SELF, QLF and APLF loss functions. For better understanding of Bayesian approach, we consider Jeffrey’s prior as non-informative prior, exponential and gamma priors as informative priors. The proposed estimators have been compared with Maximum likelihood estimator (MLE) and the uniformly minimum variance unbiased estimator (UMVUE). Moreover, the current study also derives the expressions for risk function under these three loss functions. The results obtained have been illustrated with the real as well as simulated data set.

Published: February 2023

This study offers a newly proposed distribution called alpha power Lomax (APL) distribution as a new extension of the Lomax distribution using the alpha power transformation (APT) method. Some distributional properties of newly defined distribution such as density function, moments, hazard and survival functions, orders statistics etc. are investigated. Parameters of the APL distribution are estimated with the help of the maximum likelihood (ML) estimation method. The applicability of the APL distribution is conducted through a simulation study and a real data example.
Sub-wavelength, phase-sensitive microscopy of third-order nonlinearity in terahertz frequencies
Authors: Zhu Hanyu , Lin Tong , Xu Rui , Chen Xiaotong , Guan Yuxuan , Yao Mingxing , Li Xinwei
Published: February 2023

The third-order nonlinear susceptibility χ³ occurs universally in materials and can provide label-free fingerprint of materials’ electronic, vibrational, and structural information. One quantitative spectroscopic method to access low-energy resonances of χ³ is the terahertz electric field induced second harmonic generation (TEFISH), particularly suitable for centrosymmetric materials without second-order processes. However, quantifying TEFISH requires light sources with high spectral intensity, which is challenging for the “new terahertz gap” frequencies between 5-15 THz that, not by coincidence, is the fingerprint phonon bands for many solid-state materials. Here we report the realization of phase-sensitive heterodyne TEFISH microscopy offering simultaneous temporal, spectral, and spatial resolution in the frequency range of 4 to 18 THz for the first time. Using chirped pulse difference frequency generation, ee generated intense and frequency-tunable narrowband terahertz fields, and then demonstrated time-resolved hyperspectral TEFISH microscopy in polymer thin films (SU-8), 2D crystalline semiconductors (MoS₂), and a sub-wavelength terahertz resonator. By interfering the nonlinear emission with a local oscillator field, we retrieved both the amplitude and sign of TEFISH, quantitatively resolved the nonlinear spectra, and observed the resonance features of the samples with high sensitivity. The spatial resolution is much better than the diffraction limit of the terahertz excitation due to the short wavelength of the visible TEFISH signal. Our compact implementation of TEFISH allows ultrafast time-domain imaging of vibrational and polaritonic resonances in micro- and nanoscale quantum materials.

A KAPOCS csoport olvasáskutatásában hangsúlyos szerepet kapott a digitális platform- és eszközhasználat változásainak vizsgálata. Az erre vonatkozó kérdések és válaszok azt mutatják, hogy a vizsgált korcsoportban jelentősen növekedett a (nem feltétlenül irodalmi) szövegek online fogyasztása; az információgyűjtés és a kapcsolattartás, ill. a közösségi tevékenységi formák ugyancsak digitális platformokon valósulnak meg. Feltételezésünk szerint ezt a folyamatot csak erősítette a Covid okozta fizikai bezárkózás; az online oktatás jelentősen növelte a képernyőidőt.

A tanulmány elsődleges célja a napjainkra kiteljesedett digitális tér emberének kultúrafilozófia szempontú leírása. A dolgozat megkísérli tisztázni a digitális tér státuszát az állam és a társadalom klasszikus definícióinak tükrében. A vizsgálat során transzparenssé kell tenni azt az összefüggést, ami a digitális létmód és közösségalkotás képességének és igényének torzulása között áll fenn. Mivel a homo digitalis már nem cselekszik, hanem valamely digitális eszköze segítségével villámgyors műveleteket hajt végre, már nem időzhet el egy-egy kérdés mellett, azt kontemplatívan latolgatva. Az információdömping ab ovo ki is zárja ezt. A homo digitalis filozófiai antropológiai vizsgálatának eredményeiből a kutatás arra következtet, hogy a digitális hipertér emberei közötti kommunikáció felszínes, nem eredményez igazi együttműködést.

Published: February 2023

Consumer preferences are greatly influenced by eating and cooking qualities of rice grains, along with the economic value of a specific rice variety. This study was to evaluate ten rice varieties including the check variety IR64 on their physicochemical, cooking and eating qualities as well as to identify their genetic diversity using SSR markers. Most rice varieties are medium-grain types based on length-breadth ratio, whereas the famous Myanmar rice variety, Paw San Bay Kyar, (PSBK) is bold. PSBK showed the best cooking and eating quality traits with intermediate amylose content (AC), intermediate gelatinization temperature (GT), soft gel consistency (GC), and the highest elongation ratio among the studied rice varieties. Seventeen SSR markers linked with cooking and eating traits were used to assess the extent of polymorphism and genetic variation among ten rice varieties. There were 49 alleles in total, with an average of 2.88 alleles per locus. RM592 had the maximum number of alleles. The average PIC value ranged from 0.22 (RM540) to 0.77 (RM592). Cluster analysis with UPGMA method based on Jaccard’s similarity coefficient divided ten rice varieties into two main groups and four sub-clusters. In multiple regression analysis, RM190 and Wx primers were discovered to be significantly associated with AC, GC and GT of cooking and eating quality traits. This study could contribute to the choice of rice varieties with superior cooking and eating qualities for rice breeding programs by implementing physicochemical characteristics and molecular analysis.
Historia, kreacja i opowieść, która je łączy. Sposoby funkcjonowania wątków słowiańskich we współczesnej rodzimej fantasy
Authors: Mazurkiewicz Adam
Published: February 2023

Artykuł jest studium przypadku poświęconym sposobowi uobecniania wątków słowiańskich we współczesnej polskiej twórczości fantasy. Przywołane tu teksty są zarazem reprezentatywne dla dwu dominujących w rodzimej fantastyce słowiańskiej strategii artystycznych:• nastawienia na eksponowanie historycznego wymiaru fabuły;• uwypuklenia kreacyjnego aspektu opisywanych przygód.Konfrontacja komiksów Christy i powieści Terakowskiej uświadamia, do jakiego stopnia funkcjonujące w imaginarium communis wyobrażenie słowiańskości sytuuje się między tym, co rekonstruowane dzięki ustaleniom historyków i archeologów, a tym, co zostaje kreowane na potrzeby opowieści mocą artystycznej wyobraźni. Linia podziału przebiega przy tym nie tyle między poszczególnymi tekstami kultury, co w poprzek nich. Obie artystyczne wizje Słowiańszczyzny łączy poszukiwanie wspólnoty duchowej (dotyczy to zwłaszcza Samotności Bogów) w realiach odrzucenia jej dotychczasowej, utrwalonej tradycją, zinstytucjonalizowanej formuły.
The laboratory journey to become a decision engine: a roadmap for diagnostic transformation
Authors: Lange Florian
Published: February 2023

Laboratories and diagnostic departments are presiding over a massive amount of data they are failing to fully leverage it. Data is the new black gold of healthcare organizations and by extracting insights from it, laboratories could become true decision engines, able to drive action across healthcare. This opinion paper responds three fundamental questions: (1) Where are we (diagnostic parties)? Taking a look at the most significant trends and challenges in healthcare and shedding some light upon the status of diagnostics. (2) Where do we want to be? Reviewing the opportunities for digital health, its role in the healthcare of the future and providing inspiration about what success looks like. (3) What do we need to do? Explaining what Digital Health Solutions (DHS) from Abbott is doing in this regard. This will include information about how DHS can impact the Diagnosis Cycle and how to set a roadmap for laboratories and diagnostic organizations. Diagnosis Cycle means the different steps in the diagnosis process, from the beginning when a patient is seen by a clinician and some tests are ordered, until the results are reviewed by the clinician and the treatment, follow up or discharge is decided.
Sobre la mirada decolonial de Mía Gallegos: Apuntes sobre Una mirada decolonial en torno a la novela Limón Blues
Authors: Solórzano-Castillo Alejandra
Published: February 2023

La autora Mía Gallegos nos ofrece varias coordenadas para emprender el camino de reflexión sobre Limón Blues de Anacristina Rossi.  La primera es el análisis de/colonial, abiertamente expuesto como motor de su reflexión; la otra, que suma a la mirada decolonial, es la del análisis interseccional.  Gallegos hilvana el análisis retrospectivo de las racionalizaciones y justificaciones del binomio modernidad/colonialidad y de las ramificaciones dicotómicas de poder, sostenidas en las categorías mentales propias de la colonialidad para mostrarnos cómo estas delinean los personajes de la novela de Rossi en el marco de su dimensión histórica, política, social, identitaria y de género. La interseccionalidad refiere, por su lado, al entrecruzamiento macro de las novelas Limón Blues de Rossi y Orlandus, de Virginia Woolf, para dar por resultado un exquisito ensayo crítico de una de las escritoras contemporáneas más importantes de Costa Rica.

Los derechos humanos y su protección en el ámbito interamericano e internacional: El caso Lhaka Honhat, Salta, Argentina
Authors: Soriano Gonzalo Victor Humberto
Published: February 2023

El propósito de este artículo es, por un lado, reflexionar y problematizar la noción de derechos humanos en América Latina. Por otro lado, describir y analizar los instrumentos y mecanismos de protección internacionales e interamericanos de los derechos humanos que promueven herramientas para su respeto y garantías para todas las personas. Por último, se procura analizar el caso Lhaka Honhat, teniendo en cuenta los marcos institucionales que el Sistema Interamericano de Protección de los Derechos Humanos emplea ante la alegada violación del derecho a la propiedad en perjuicio de las comunidades indígenas de la localidad de Rivadavia, Provincia de Salta, Argentina.

El interés de abordar estos objetivos retoma la idea de pensar la protección de los derechos humanos como respuestas normativas a problemáticas y necesidades que acontecen en la sociedad. De tal modo, se recurre a herramientas teóricas para discutir las concepciones que giran en torno a cómo se entienden los derechos humanos en la actualidad, y de qué manera ciertos instrumentos, mecanismos y sistemas a nivel internacional e interamericano promueven su protección respecto a los pueblos indígenas. En consecuencia, se asume que los derechos humanos componen un campo de luchas sociales, históricas y culturales por la dignidad, entendiéndolos como el acceso igualitario a bienes necesarios para la vida, cuyos resultados deben garantizarse por normas jurídicas, políticas y económicas.

Major challenges in engineering and its role in society
Authors: Peña-Reyes José Ismael
Published: February 2023

Engineering has a long historical tradition; it began as a discipline in the sixteenth century and reached maturity during the twentieth century. However, the twenty-first century's features strongly differentiate it from earlier times; when referring to this period, we speak of globalisation, knowledge society and national innovation systems. This is a period marked by contradictions. Technological developments and social and political changes have improved human beings' quality of life. New technologies have provided the context for its opening decade: nanotechnology, microelectronics and nanoelectronics, photonics, materials science, biotechnology, information and communications technology, logistics, medical engineering and renewable and clean energy. Technologies feed each other and off each other, offering endless possibilities for development. This is a time where the doors of political democratisation, art and culture have opened; however, it is also a world facing political, financial and environmental crisis. Colombia, particularly, is a country encountering problems regarding its competitiveness, having crippling levels of corruption and impunity, problems related to education, health and infrastructure. Colombia needs more engineers who can contribute towards resolving complex problems. Such engineers must have had excellent technical and humanistic training; they must be creative, able to work as a team, have become leaders who can listen and communicate and help develop a world to ensure that humans and other living species on earth can flourish with a uniform, durable level regarding their quality of life. Work must thus be done on critical engineering education and the present work presents some characteristics concerning what these engineers training/education should be.
Power Quality Problems Caused by Termites on 138-kV Underground Cables
Authors: Fuscaldi Romeu , Silveira Fernando H. , De Conti Alberto , Visacro Silvério
Published: February 2023

This paper discusses problems found in the operation of underground cables in the transmission system of CEMIG, with emphasis on insulation failures caused by termites. This problem has been the source of many scheduled and non-scheduled interruptions in later years, leading to significant maintenance costs. Experience with current practices designed to detect and prevent this failure mode is described. It is argued that new procedures are needed for improved on-line, pre-failure detection. Test improvement will hopefully contribute to increase the lifetime of underground cables currently in use, as well as to reduce maintenance costs.
Analysing transfer phenomena in osmotic evaporation
Authors: Forero Longas Freddy , Vélez Pasos Carlos Antonio
Published: February 2023

Osmotic evaporation is a modification of traditional processes using membranes; by means of a vapour pressure differential, produced by a highly concentrated extraction solution, water is transferred through a hydrophobic membrane as vapour. This technique has many advantages over traditional processes, allowing work at atmospheric pressure and low temperatures, this being ideal for heat-sensitive products. This paper presents and synthetically analyses the phenomena of heat and mass transfer which occurs in the process and describes the models used for estimating the parameters of interest, such as flow, temperature, heat transfer rate and the relationships that exist amongst them when hollow fibre modules are used, providing a quick reference tool and specific information about this process.
Alternatives for erosion control by using conventional coverage, non-conventional coverage and revegetation
Authors: Díaz Mendoza Claudia
Published: February 2023

Humankind's unsustainable behaviour regarding land-use has negative effects on the environment, leading to loss of fertility and degradation and desertification; this has a direct impact on the decline and deterioration of water resources, soil erosion and thus changes in the weather leading to drier conditions. The foregoing are caused by the misuse of soil. The way soil resources have suffered gradual deterioration has become evident in Colombia during recent years; this has been produced by erosion and the removal of mass caused by various factors including physical and chemical erosion. All the above, together with negative events such as global climate change and the sedimentation of rivers, means a negative environmental impact. Soil erosion and desertification are major environmental issues regarding disturbances and threats affecting the arid, semiarid and dry sub-humid Mediterranean region's geo-ecosystems in the third millennium; additionally, economic global change may exacerbate such problems (Ingram et al., 1996; Williams et al., 1996). Regarding soil deterioration, soil vegetation cover and erosion control and mitigation measures should be introduced by using mechanisms which should be as natural as possible and do not induce fresh impacts on the environment. This literature review has thus documented the state of the art regarding several alternatives for erosion control currently involving bioengineering.

The aim of this study is to present results of an investigation about the developing of a high-performance concrete (HPC) using a highly reactive pozzolan made from chemically treated rice husk ash (ChRHA) prepared by a chemical-thermal attack to the rice husk. This particular rice husk ash (RHA) consists of 99% of silica, highly amorphous, white in color and of greater pozzolanic activity than the silica fume and another rice husk ash prepared with only by a thermal treatment. The results of the physical, chemical and mineralogical characteristics of ChRHA are analyzed. In this study, the compressive strength, flexural strength, water absorption, resistance to carbonation, total charge-passed derived from rapid chloride permeability test (RCPT) and modulus of elasticity of hardened concrete were determined in the laboratory. Test results indicate that it is possible to produce HPC with the incorporation the chemically treated RHA. The incorporation of the chemically treated rice husk ash into the concrete enhances the compressive strengthand the durability properties being comparable to the properties of high performance concretes with silica fume (SF) made with the same replacement levels.
Implementation of Robotic Process Automation in Public Sector Goods and Services e-Procurement Audit
Authors: Hidayanti Ermina , Kunrat Kamia Achyuniasih , Ikram Syafrizal
Published: February 2023

Indonesia has adopted e-Procurement through an electronic procurement system (SPSE) implemented by the Electronic Procurement Service to improve transparency and efficiency in the procurement of goods and services (LPSE). Although the data/information presented in the LPSE is easily accessible, using the data in the LPSE for supervisory or audit functions is still not optimal, despite the fact that procurement of goods and services is the area with the highest corruption cases in Indonesia. The large amount of data in LPSE makes the audit process difficult because there is too much data to consider, especially if the audit process is still manual. As a result, auditors must use information technology to aid audit activities, also known as Computer Assisted Audit Techniques (TABK). In the field of public procurement auditing, the methodology for extracting large amounts of information is also unknown. Robotic Process Automation (RPA), which is thought to have great potential to facilitate audit work, is one of the information technologies that can help with the process of extracting large amounts of data. The author attempts to investigate how the implementation of RPA in the audit of the procurement of goods and services in the public sector that were analyzed descriptively in this study. The study's findings show that process automation can be done well and produce data that can be used in audits.

The implementation of MSMEs Protection Policies during the Covid-19 Pandemic
Authors: Haryaningsih Sri , Yohanes Yulius , Sihaloho Nahot Tua Parlindungan , Andriani Farah Devi
Published: February 2023

During the crisis in the last two years, the government implemented five policy schemes to protect Micro, Small, and Medium Enterprises (MSMEs). This research aims to seek how the policies scheme recovers MSME activities and provides recommendations to distribute the policies benefits evenly. This qualitative research was conducted through a literature review design. Data were collected from laws and regulations, empirical research results, and credible newspapers. Data were analyzed using the theory of Mazmanian & Sabatier (1983). This research finds that not all MSMEs can recover sales, funding, supply, operations, and diversification. Problem characteristics and policy characteristics have been mapped according to the policy scheme. However, the goals achieved are more influenced by variables outside the law. Not all MSMEs meet bankable criteria and integrate with the digital ecosystem. As a structural problem, these situations can be overcome through a derivative policy with a top-down pattern. As a cultural problem, these situations require an MSMEs mindset change. Therefore, this research recommends MSMEs' digitalization through expanding fund access and protection (insurance). This research concludes that the protection of MSMEs is only effective for the integrated digital ecosystem. Thus, a derivative policy is needed to "force" MSMEs' digitalization ecosystem.
