Determination of main performance data of an aircraft threedimensional maneuver split-S with a permissible flight envelope limiter
Authors: Zhuravsky K. A. , Kostin P. S.
Published: January 2023

Due to a steady extension of the flight envelope of modern agile combat aircraft, with the growing requirements for state tests, it is increasingly necessary to study the entire flight envelope and specifically, to determine the main performance data of individual maneuvers. Currently, state tests are based on a flight full-scale experiment, which is cost-ineffective in terms of cost, duration, and limit lines of the flight envelope. The accelerating trends to update state tests are semirealistic simulation and complex simulation modeling. The article presents the various techniques to determine main performance data of a three-dimensional maneuver split-S, which include the calculation method, semirealistic simulation, and simulation modeling. The calculation method is understood as calculation formulas expressed from the system of equations for motion of the aircraft mass center. Semirealistic simulation was carried out using a flight-simulation stand by operator pilots. Simulation modeling was conducted using a complex simulation model of an aircraft, consisting of a pilot’s control actions model based on fuzzy logic. The article provides the description, advantages and disadvantages, comparison of the results of each of the techniques. The calculation method, despite its efficiency, is the most inaccurate due to the complexity and inability to define the average flight parameters. Additionally, this method does not take into consideration such factors as the aircraft flight configuration, atmospheric disturbances, the pilot’s command profile, the logic of the permissible flight envelope limiter operation. The results of semirealistic simulation showed that this method is more accurate than the calculation one, but complex and time consuming in terms of the organization and execution of experiments. The analysis of the study illustrated that the most appropriate way to determine main performance data of split-S is simulation modeling on a complex simulation model of the aircraft, because the given method considerably saves financial and time resources used on state flight tests.

Organismos, movimientos, campos, espacios, escenarios. En torno a los debates sobre la definición de las luchas por los derechos humanos en Argentina
Authors: Alonso Luciano 
Published: January 2023

Resumen

 Desde la transición a la democracia en Argentina, se han presentado diversas alternativas respecto de los conceptos con los cuales definir las acciones colectivas en defensa de los derechos humanos. Probablemente lo que se juega en esos debates no es sólo el modo de nombrar y definir un objeto de estudio, sino la misma posibilidad de dar cuenta con palabras precisas y excluyentes del carácter abierto e indeterminado de ciertas prácticas sociopolíticas. En ese sentido, este texto revisa los supuestos teóricos de la construcción de categorías analíticas y concluye abogando por un cierto pluralismo conceptual, que facilite a los discursos académicos dar cuenta de la complejidad material del pasado.

Palabras clave

 Derechos humanos, categorías analíticas, conceptos descriptivos, pluralismo conceptual

La censura editorial en Japón entre los siglos XVII y XIX: El caso de la publicación y circulación de obras relacionadas con el cristianismo
Authors: SAN EMETERIO CABAÑES Gonzalo
Published: January 2023

Este trabajo toma como base la investigación más reciente realizada en Japón sobre los procesos de censura editorial entre el siglo XVII y el siglo XIX, también conocido como periodo Edo, para ver cómo los mismos afectaron a las obras relacionadas con la temática cristiana. El mapa resultante es una división en dos secciones cronológicamente diferenciadas. La primera de ellas, centrada en el siglo XVII se caracteriza por un control intenso de las obras vinculadas al cristianismo importadas de China y una presión indirecta por parte de las autoridades sobre los editores que publicasen sobre la temática en cuestión, incluso aunque se tratase de obras anticristianas. Dicha presión se intensificará a lo largo del siglo XVII, proceso que queda reflejado en las ilustraciones de las diferentes ediciones de obras relacionadas con la temática cristiana. La segunda parte se centra en el siglo XVIII, momento en que se construirá un sistema de control gubernamental a nivel nacional que eliminará toda posibilidad de publicar material relacionado con el pasado histórico cristiano de Japón. Este sistema se mantendrá hasta mediados del siglo XIX, pero no será capaz de frenar la distribución de obras relacionadas con esta temática, que experimentará un nuevo resurgir gracias a la transmisión de textos manuscritos al margen de los cauces editoriales más convencionales.

The Admissibility of the Detention of Minors in Guarded Centers for Refugees in the Context of the Principle of Best Interests of the Child
Authors: Lis-Staranowicz Dorota
Published: January 2023

The glossed ECHR judgment concerns the extension of detention in a guarded center of an Armenian family seeking international protection. The Court has found that Poland breached art. 5 par. 1 (f) of the Convention for the Protection of Human Rights and Fundamental Freedoms. It has upheld its position expressed in the case of Bilalova and Others v. Poland (application no. 23685/14), that “Various international bodies, including the Council of Europe, are increasingly calling on States to expeditiously and completely cease or eradicate the immigration detention of children. The Court has found that the presence in a detention centre of a child accompanying its parents will comply with art. 5 par. 1 (f) only where the national authorities can establish that such a measure of last resort was taken after verification that no other measure involving a lesser restriction of their freedom could be implemented […]”. Therefore, the “rule of no recollection” operating in Polish legislation may be an additional test verifying the admissibility of minors’ detention in guarded centers.

Authors: Juliana Juliana , Sihombing Sabrina Oktaria , Antonio Ferdi
Published: January 2023

The experience economy approach shows that consumers are not only offered a product as a commodity but as an experience. Experience in a destination will distinguish one place from another. The purpose of this research is to examine the four categories of experiences owned by the Keranggan Tourism Village and to provide a product development strategy based on that experience. The four categories are aesthetic experience, entertainment, education, and getting out of the routine. Kampung Keranggan has been developed since 2012 and already has several tourist attractions that are visited by tourists. The research method used is descriptive qualitative. Data collection was done by interviewing the Tourism Awareness Group and field observations. The findings of this study are that Kampung Keranggan already has aspects in realizing the experience, but the packaging still needs to be developed. Among them, the educational experience for tourists is given the experience of food processing production, from harvesting cassava, peeling, steaming, and mashing to forming opaque chips. The results of this experience study will be included in the tourism product development strategy.

El impacto inicial de una lesión de la médula espinal (LME) es siempre devastador, tanto para la persona, como para la familia. Hace apenas sesenta años la expectativa de vida para cualquier persona con LME en el mundo no sobrepasaba más que algunas semanas o meses. La situación mejoró significativamente gracias al trabajo de eminentes pioneros de la medicina, principalmente en Europa y en los Estados Unidos. En América Latina y el Caribe, aunque los recursos humanos capacitados y los servicios de salud para las personas con LME han mejorado notablemente en los últimos años, queda aún mucho por hacer. Para muchas personas con esta lesión la situación continúa siendo angustiante y poco esperanzadora. Ello nos enfrenta a grandes retos que exigen, al mismo tiempo, inmensos esfuerzos, compromisos, alianzas y cambios en políticas públicas y dentro de los sistemas de salud.
The Effects of COVID-19 on Informal Traders in Undesignated Spaces
Authors: Ndhlovu Emmanuel , Mhlanga David
Published: January 2023

The literature on COVID-19 impacts overlooks the pandemic’ impact on informal traders who operate in undesignated public spaces. While studies on the impact of COVID-19 on informal traders exist, there remains little focus on how the socio-economic livelihood activities of informal traders in undesignated public spaces, such as parks, who rely on both domestic and international tourists as customers, have been impacted. This paper fills this gap by focusing on two case studies of urban public spaces in the city of Tshwane, South Africa. These spaces are Jubilee Square and Magnolia Dell Park. The study is predicated on the spatial triad framework which enables it to interrogate how the restriction on access and utilisation of public spaces during the COVID-19 lockdown impacted on the socio-economic activities of informal traders. It found that informal traders in these two parks were the most vulnerable category of traders during the COVID-19 lockdown and faced huge socio-economic and livelihood challenges. They lost their income sources and had their social networks disrupted. The article proposes social policy interventions in the governance of public spaces as part of an effort to save both lives and livelihoods in the face of a pandemic. Doi: 10.28991/ESJ-2023-SPER-07 Full Text: PDF

Kejadian banjir di musim hujan merupakan hal biasa bagi sebagian masyarakat Indonesia terutama bagi mereka yang tinggal di perkotaan. Kejadian banjir akhir-akhir ini semakin meningkat baik intensitas maupun frekuensinya, menyebabkan kerugian material yang sangat besar dan tidak jarang menelan korban jiwa. Hal tersebut berkaitan erat dengan semakin masifnya kerusakan Daerah Aliran Sungai yang disertai perubahan iklim global. Pengendalian banjir yang dilakukan pemerintah (pusat dan daerah) bersifat sektoral dan berfokus pada pendekatan sipil teknis nampaknya belum efektif mengendalikan banjir saat ini. Lahan pertanian dan kehutanan memberikan kontribusi signifikan penyebab banjir di Indonesia, sehingga pengendalian banjir dengan pendekatan vegetatif-agronomis menjadi sangatlah penting.

Published: January 2023

Pengawasan perikanan berperan penting dalam mewujudkan perikanan yang berkelanjutan. Penghapusan kewenangan pemerintah kabupaten/kota dalam hal seluruh pengawasan perikanan pada UU No. 23/2014 menciptakan kekosongan tugas dan fungsi pemerintah kabupaten/kota dalam pengawasan perikanan di perairan darat yang baru disadari beberapa tahun berikutnya. Adanya regulasi tersebut menyebabkan hilangnya bidang pengawasan perikanan di Dinas Perikanan Kabupaten/Kota yang berujung pada ketiadaan unit kerja, keterbatasan SDM, dan kurangnya pembiayaan. Oleh sebab itu, pengakuan terhadap peran pemerintah kabupaten/kota terkait pengawasan perikanan di perairan darat menuntut adanya penguatan peran dan sinergisasi antar lembaga dalam menyelenggarakan urusan bidang pengawasan sumber daya kelautan dan perikanan.

Companies with assessment criteria often consider only the leader's subjectivity and ignore other criteria. Limited appraisal criteria result in shortcomings in the decision-making process. This study examines the performance appraisal in a plastic manufacturing company's production floor and develops a multi-criteria decision-making model for performance appraisal by considering company criteria. We propose a qualitative approach using the analytic network process to determine the weighted criteria and sub-criteria to evaluate performance by involving all criteria. The results show that qualitative performance criteria yield higher scores for workers than the quantitative performance criteria, thereby confirming that subjectivity and qualitative criteria influence performance appraisal in the manufacturing industry. A multi-criteria decision-making model is required in performance appraisals to determine the overall measurable criteria. Moreover, this study contributes to an empirical solution for achieving an effective human resource management system.

The aim of this study is to evaluating an Organic Rankine Cycle (ORC) system from diesel engine waste heat recovery by selecting three different working fluids with different pressure and temperature condition. The working fluid include N-Pentane, R-245fa, and R-134a are conditioned on variations in pressure and evaporation temperature with a difference of 0.5 bar and 5 °C to achieve the best thermal efficiency. The proposed evaluation involved two phases, first is analysis of the working fluid with various condition is carried out using REFPROP software and then results of that analysis will be used as the basis of input in calculating the overall heat balance using the Cycle Tempo software. This study found that a diesel engine with a capacity of 1000 kVA wastes energy of 1177 kW which is released through exhaust pipe and engine radiator can produce a turbine power of 144,47 kW. The highest thermal efficiency of 13.48% was obtained by using the working fluid R-245fa at the evaporator pressure and temperature of 23.5 bar and 154 ⁰C, respectively.

The paper proposes a novel Antenna-in-Packaging (AiP) structure design for 60 GHz, millimeter wave WiFi applications. In the AiP design, single-or double-sided glass redistribution layers were embedded in a typical fan-out (FO) packaging structure to introduce design flexibility and to improve the radiation properties of the antenna. ANSYS-HFSS software was employed for electromagnetic (EM) characteristic simulations on the fan-out AiP (FO_AiP) design. To improve antenna radiationperformance, single factor analyses were first performed to study the impact of each of the design parameters. A consecutive procedure followed to find more suitable combinations of the design parameters. As a result, two typical glass-embedded FO_AiP structures -one with 7.6 GHz bandwidth plus 4.7 dB gain and upward radiation, and another with 5.3 GHz bandwidth plus 5.2 dB gain and downward radiation, are proposed for the 60 GHz applications.

Published: January 2023

The microgrid (MG) is a coordinated collection of different distributed generation (DG) typesthatsupply local demandthrough a distribution network. MG may operate in two different modes: grid-connected (GC), and islanded (IS)modes.The fault current valuevaries significantly between the GC and IS mode for a MG with inverter-based distributed generators(IBDGs). The fault currents are minimal in the IS mode owing to the power electronics equipment have a limited current carrying capacity. Therefore, the coordination of traditional overcurrent (OC) protection is difficult for these two operation modes. Therefore, a comprehensive MG protection scheme should be established to safeguard MG against all kinds of faults. The main protection strategy proposed in this paperis a positive sequence differential current protection scheme. The envisioned concept can overcome the protective device coordination problems, and all fault types can be detected during both operation modes of MG for radial andloop configurations. The validation of the proposed design is performed using PSCAD/EMTDC software. The results indicate that the maximum fault clearing time for the main protection in GC mode and IS modeisof 31.5 ms and 34 ms respectively.

Fuel economy and emissions reduction are the vital tasks, which are currently being solved by dismissing cars with only internal combustion engines to the benefit of electric and hybrid electric vehicles (HEV). HEVs have a significant advantage over electric vehicles, namely a bigger drive range and independence from the charging stations at hand. However, high cost and big weight of HEVs discourage their wider use. To minimize the cost and weight of HEV, the algorithm of its power plant operation is changed. This paper presents a method for calculating the electric drive mode of a hybrid vehicle in accordance with the proposed algorithm for the power plant operation. The results of calculation of the main characteristics are presented and analyzed. The experimental studies were carried out with the hybrid vehicle developed on the base on the Lanos pickup vehicle. The research results showed good agreement between the experimental and the calculated results. The proposed technical solution is presented as practical and effective. The results of this work can be used in the automotive industry. The development helps to reduce the cost and weight of hybrid vehicles, maintaining their operational characteristics and good economic and environmental indicators.

The problems of releasing and identifying features of key elements and their identification in images are shown. The basic algorithms and methods for forming descriptors for key elements in the image are considered. The main disadvantages of existing methods in aerospace images are the loss of stability and the presence of a large number of false key elements when changing recording to theconditions (for example, brightness and contrast of the received images). To eliminate these drawbacks, it is proposed to use selected lines as key elements, and their geometrical characteristics to form a descriptor. To analyze the proposed algorithm andthe SIFT method, fragments of aerospace images changed in brightness and contrast in a graphic editor from -50 to +50 percent of the original were used, which made it possible to evaluate the operation of these algorithms in conditions close to the real survey. It is shown that the proposed algorithm is more stable than the SIFT method with increasing contrast and decreasing the brightness of the test aerospace image. Also, the proposed algorithm is characterized by a smaller number of detected false key elements compared to the SIFT method.

The maximum power extraction using single integral sliding mode control scheme is established from the sliding mode control scheme. The sliding mode control (SMC) scheme extracts the maximum power during the partial shading weather conditions using the effective selection sliding surface duty cycle ratio in combination of dc/dc boost converter. This dynamic operation of sliding surface selection operation in partial shading conditions aids to enhance the solar panel efficiency compared to the other existing MPPT schemes. The effective dynamic operation of sliding surface mode control is designed using feedback loop control scheme to diminish the steady state voltage error of the solar panel, further to obtain the higher sliding duty cycle ratio. The dc-to-dc boost converter is made active using sliding duty cycle ratio as input gate signal boost converter switch. Hence, higher efficiency attains at higher sliding surface duty ration. This sliding surface duty ratio is limited in sliding mode MPPT control scheme and requires the necessary advancements to achieve the maximum duty cycle ratio. The single integral sliding mode control scheme (SISMC) offers the enhanced sliding surface duty cycle ratio with integration of voltage error obtained in SMC scheme. Therefore, the major application of SISMC compared to SMC scheme is the proposed SISMC schemeoffers the effective dynamic sliding operation using integrated steady state voltage error signal and allows to nullify the lacuna of maximum sliding duty cycle ratio. Hence, this paper aims to discuss the design and performance analysis of SMC scheme and proposed SISMC MPPT control scheme. To corroboratethe performance of the proposed SISMC MPPT scheme, the MATLAB / Simulink model was designed and verified. Also,this paper presents the comparison results of proposed SISMC MPPT schemes with the SMC scheme.

In recent decades, restructuring has cut across all probable domains, involving the power supply industry. The restructuring has brought about considerable changes whereby electricity is now a commodity and has become a deregulated one. These competitive markets have paved the way for countless entrants. This has caused overload and congestion on transmission lines. In addition, the open access transmission network has created a more intensified congestion issue. Therefore, congestion management on power systems is relevant and central significance to the power industry. This manuscript reviews few congestion management techniques, consists of Reprogramming Generation (GR), Load Shedding, Optimal Distributed Generation (DG) Location, Nodal Pricing, Free Methods, Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Fuzzy Logic System Method, as well as Additional Renewable Energy Sources. In this manuscript a review work is performed to unite the entire publications on congestion management.

It has been recorded so far that the earthquake in Indonesia has damaged many publicfacilities and claimed many victims. Most cases of casualties were not caused directly by the earthquake but as a result of falling debris from buildings that were unable to respond to the earthquake. To avoid similar incidents in the future, all buildingsin Indonesia need to be inspected and ensured that they are safe from the threat of an earthquake, and school buildings are no exception. The absence of a specific assessment tool for earthquake-resistant school buildings underlies this research. The assessment tool was developed based on the results of a literature review of several building inspection standards in various countries. Several research variables that were previously identified were then validated and processed using the Analytical Hierarchy Process method. Some experts in related fields were involved in the process to formulate the significant variables, the respective weights as well as scoring systems. This research produced a preliminary assessment tool in two parts. The first one, which emphasizes examination by visual method, is translated into four new categories: Building Slope Inspection, Sub-structure Component Inspection, Upper Structure Component Inspection, and Document Inspection, with 12 sub-categories and 28 indicators. Meanwhile, the second part emphasizes on the non-destructive testing as additional scores. It includes three types of tests for concrete and two tests for steel materials. Finally, the level of preparedness for the structural components of a good school building needs to meet a minimum score of 70.
