Simulation of Deployable Cable Nets for Active Debris Removal in Space
Authors: Fisicaro Paolo , Pasini Angelo , Valvo Paolo S. 
Published: December 2022

Abstract
Deployable cable nets have been proposed as promising systems for the active removal of space debris. The modelling and analysis of such systems during deployment, capture, and post-capture phases are crucial for the effective design of an operative mission. To this aim, accurate and effective simulation tools are necessary. We propose a finite element model of the cable net with lumped nodal masses and first-order cable elements. The nodal positions are assumed as the main unknowns of the problem. The large displacements and finite deformations are described by the Green-Lagrange strain tensor. The cable elements are assumed to react only in tension. Global damping is considered in line with Rayleigh’s hypothesis. The governing equations are solved numerically by means of the Runge-Kutta method with a variable time step. As an illustrative example, we present the simulation of the in-plane deployment of a planar, square-mesh net. The proposed approach turns out to be computationally effective, even if the accuracy of the numerical integration scheme needs to be improved, particularly in the final stages of deployment.

Authors: Marchewka M , Zubrzycki J 
Published: December 2022

Abstract
A cataract is a disease of the 21st century. In highly developed countries, the opacification of the intraocular lens is removed and replaced with an implant. This article discusses the essential aspects related to the construction of implants that imitate the natural lens of the eyeball. The research was carried out owing to X-ray microtomography. Observer design differences in the two lenses' structures contribute to the implant's quality in question. The study aimed to check and compare two types of implants in terms of the design and manufacturing quality of the given lenses. The common element of the implants in question was their material and manufacturer. Lenses of the same material were used to maintain the same optics. The results gave a comparison in terms of the quality of the product in terms of the creation and modelling of the lenses than the properties of the material itself from which they were made.
Climate change to increase crop failure in U.S.
Authors: Kim Seung Min , Mendelsohn Robert 
Published: December 2022

Abstract
The literature has documented that climate change is likely to reduce crop yields of harvested acres in the United States. This study uses panel data methods to document that climate change could also reduce harvested area. We find that ‘crop failures’ are sensitive to spring and fall temperature conditions. Using perturbations of temperature and precipitation conditions, we show that a uniform 1 ∘C increase in temperature across the U.S. with no adaptation is expected to cause about 3.2 million additional failed acres in the United States, which is equal to a 0.9% decline in acreage. These harmful impacts are predicted to be stronger in the southern than northern United States. For illustrative purposes, we also examine a uniform 3 ∘C warming scenario with no adaptation, and project that damage increases to 11 million lost acres, about a 3% decrease in crop acreage. Projected increases in local precipitation have little effect. The effect of crop failure must be added to previously measured reductions in crop yields from harvested acres, implying climate change is likely to be more harmful to American crop production than previously thought.

Published: December 2022

Abstract
Evaluation of vehicle aerodynamics is an integral part of automotive engineering. The aerodynamic performance of automobile has great influence on the power performance, economy, handling stability and ride comfort of the vehicle. In this context, the present work focuses on improving the aerodynamic performance of a modelled sports vehicle using numerical techniques. Baseline analysis of a research paper was conducted for validation of the results obtained in numerical simulations. Multiple turbulence models, flow boundary conditions, and inlet parameters were explored using Ansys Fluent Computational Fluid Dynamics software. The validation of the baseline data was proved using convergence, numerical and theoretical validation. Solution convergence parameters were Absolute Residual criteria and Mass Flow Rate. Grid Independency, Inlet Velocity and Flow Turbulence Model checks were employed to further refine the accuracy of simulations. This research studied and presented the effects of a two-flap spoiler on the aerodynamic performance of the vehicle using pressure, velocity, and eddy viscosity contours using simulations of incompressible air flow over the modelled car body. Improved flow contours exhibited a reduction of Coefficient of Drag and Lift parameters. Using Coefficient of Pressure (Cp) as a baseline parameter, multiple configurations of flow boundary conditions were explored. The literature consists of theoretical, experimental, and numerical aspects of the research papers and journals that were studied for this research. The objectives were to model, mesh and simulate a sports car to better understand the flow vortices and validate the aerodynamic flow parameters with the studied literature.

Published: December 2022

Abstract
Demand response (DR) is a high priority smart grid technology yet, efficient implementation of the same at the circuit level is often overlooked. Technologies like DR is vital to the improvement, stability and reduction of congestion in the grid. At the distribution side, addition of photovoltaic (PV) systems with appropriate metering has made consumers to prosumers. Prosumers contribute to the grid supply and often meeting increased demand. PV installation has made surplus grid power available. Power from PV is an environment friendly approach, in-order to yield its maximum benefit, it should be appropriately connected with advanced metering infrastructure (AMI). Further, AMI enables other technologies like real time pricing (RTP), DR and demand side management (DSM). Pilot projects put forward by Government of India (GOI) has already deployed smart meters, transforming existing conventional meters into AMI. Hence, functional benefits of AMI are to be studied to its full usage potential. DR and RTP are more focused on consumer behaviour and involvement whereas, DSM is under the control of utility. Hence, novel layouts for energy efficient prosumers with net-metering, gross-metering, hybrid loads and renewable PV integration are analysed. Consumer feasibility of DR without compromising, basic needs of power availability and comfort is focused. Inference is made from both metering infrastructures, tariff schemes and its application in Puducherry locality of India.

Published: December 2022

Abstract
Steel-concrete composite beam is a typical construction which is made up of two dissimilar materials such as steel and concrete. It is used mainly for construction of commercial/residential high-rise buildings and bridges. From last few decades steel-concrete composite structure has been utilised in construction industry due to several advantages such as reduced time and cost of major construction and the avoidance of one of the major issues in present era, space scarcity. Shear connector is a basic component through which steel and concrete components are mechanically connected to transfer the load from concrete slab to steel beam in a conventional type of steel-concrete composite beam. Three dimensional numerical models are created using finite element analysis commercial software package ANSYS15 to study the flexural capacity of beam specimens. Earlier, validation has been done with the test results available in the literature and the proposed model is found to be capable of analysing the specimens with acceptable accuracy. Further numerical models are made to understand the behaviour of steel-concrete composite beam which is made up of two different flexible shear connectors such as stud and channel connector under four-point bending. Degree of shear connection, geometry and layout of shear connectors are taken into account as key parameters for this present numerical study. Normal strength of concrete is considered. The associated results such as ultimate load, mid-span deformation, interfacial slip capacity are presented. Diameter along with length of stud connector is found to influence the load carrying capacity of beams. Ultimate load capacity as well as stiffness of beams is found to enhance when channel section is considered with minimal spacing of connector. Thus finding the required degree of shear connection was also proved to be vital for assessing the performance of steel-concrete composite beams.

Published: December 2022

Abstract
Microalgae as a third-generation biofuel source with various advantages is a potential part of renewable energy resources. Various studies on the conversion process of microalgae into biofuels have been carried out, one of which is the thermochemical process. The thermochemical conversion process is considered better than the biochemical process which has a low conversion rate and higher production costs. Recent researches state that to obtain bio-crude oil from microalgae through a thermochemical process, there are two alternative technologies that can be used, which are pyrolysis and liquefaction. In this research, a selection was made to determine which technology was better using decision making tools of Analytic Hierarchy Process (AHP) method. The evaluation criteria that have been used are technological (readiness level, energy efficiency, pre-treatment process, and product output), operational complexity, environment, and economy (investment cost and operation cost). The alternative technologies evaluated were pyrolysis with bubbling fluidized bed reactor, pyrolysis with circulating fluidized bed reactor, and hydrothermal liquefaction. From the results of pairwise comparisons, the technological criteria had the highest weight (0.343) and hydrothermal liquefaction technology was the best alternative technology among other alternatives (0.420).
Preliminary Experiment on Reservoir Sediment Flushing
Authors: Laksitaningtyas A P , Legono D , Istiarto  , Jayadi R 
Published: December 2022

Abstract
Prediction of reservoir sediment flushing requires a large amount of sample data obtained from long-term field measurements. Before running the complete laboratory experiments to understand the flushing mechanism, preliminary experiments using an acrylic tank and a simple piping system were carried out. The acrylic model consists of a constant head tank and a reservoir model. The constant head tank is a model that ensures a continuous and consistent flow rate contribution to the next model component, namely the reservoir model. The Reservoir model is a component for modeling the sediment flushing process, where the sediment deposits have been prepared. The reservoir sediment flushing experiment used a bottom outlet with a circular hole connected by a pipe to a valve to release sediment. The valve is assumed to be a sluice gate that can be opened and closed for sediment flushing. Preliminary experiments show that the model can simulate the flow of reservoir sediment flushing through the bottom outlet with stable reservoir water depth, operation of sluice gates, and the presence of scour cones in the sediment.

Published: December 2022

Abstract
The extreme climate change can result in long dry season or high rainfall, thereby can affect water supply. Water supply highly influences paddy and fish productivity in Mina Padi (paddy-fish integration farming system) pattern. This research aims to analyze the Mina Padi farmers’ adapting strategy in dealing with climate change and the effect of adapting strategy on paddy and fish productivity. The research took place in Mina Padi area of Sukoharjo Regency, Central Java. This research employed a qualitative method with descriptive analysis. The informant of research consisted of farmers and extension officers selected using purposive sampling technique. The result of research shows that the Mina Padi farmers’ adapting strategy in dry season includes closing caren, the channel made in the deepest part of farming lot (the fish pond is concentrated in the front part of farm). The quality of production with caren is better than that without it. Paddy will not be attacked by pest when there is caren, because pest will be preyed directly by fish. The number of fish sowed is the same when there is and there is no Caren, but qualitatively the fish develop more rapidly than those concentrated in the pond only.

Published: December 2022

Abstract
Today, information technology plays an important role in public service, especially as the world grapples with the corona pandemic (covid-19). This is characterized by the increasing ease with which correspondence and information can be transferred from one location to another. Although the use of information technology includes several interrelated activities such as data, processing, information management, and electronic-based work systems to provide many conveniences, it has not been widely used in maximizing public services due to the apparatus’s limited skills. The goal of this study is to discover the application of information technology, public services, and the relationship between the two in Cipotakari Village, Panca Rijang District, Sidenreng Rappang Regency. The findings revealed that the application of information technology and public services is still quite good, but is becoming less so. While the influence of the application of public technology on public services shows that there is a significant and very significant influence in the corona pandemic, the authorities have proven to use a lot of information technology in providing services to the public.
High-efficiency broadband blazed metagrating working in visible light
Authors: Lin Yu , Han Yeming , Wang Chengmiao , Li Bowen , Zhang Jianyu , Deng Yongbo 
Published: December 2022

Abstract
A simple 1D blazed metagrating is proposed. The metagrating consists of SiO2 film sandwiched by Ag substrate and Ag nanostrips, which can achieve high-efficiency −1st-order diffraction in the range of 550 nm to 700 nm, and the peak efficiency is nearly 98%. The SiO2 dielectric layer in previous designs is used chiefly as a waveguide layer to support a guided mode. In comparison, it is introduced here to suppress the unwanted diffraction order (zero-order), which helps achieve high-efficiency diffraction at a high diffraction order. For analysis, the metagrating is disassembled into two parts, including a flat plate and a grating. By analysing the far-field radiation pattern of scattered waves and the reflection phase of a specific mode for these two parts, we conclude that the cause of high-efficiency blazing draws support from suppressing zero-order based on destructive interference. This work provides an intuitive physical image for this type of metagrating and an idea to design high-efficiency diffraction and beam deflection devices from the perspective of interference.
Coupled model analysis of the ablative Rayleigh–Taylor instability
Authors: KUANG Yuanyuan , LU Yan , LIN Zhi , YANG Ming 
Published: December 2022

Abstract
The weakly nonlinear stage of the ablative Rayleigh–Taylor instability (ARTI) is investigated by expanded hydrodynamic equations in which the third-order corrections of the two-mode perturbations are considered. In the present coupling model, two linear perturbations are simultaneously added near the ablation front at the initial moment, and we have derived the first three coupling harmonics. Furthermore, the coupling model analysis is studied via direct numerical simulation as well. When the original two fundamental modes are always dominant over other modes, the time evolution of the density amplitudes for these modes agrees well with the results of direct numerical simulation. It is found that the harmonics are stabilized by the mode coupling effects, and the long wavelength mode of the fundamental modes tends to dominate the growth of the ARTI. Two-mode coupling is one of the restriction factors for the realization of controlled inertial confinement fusion. Therefore, the coupling harmonics excited by two-mode perturbations have good application potential and are worth further study.

US Military Deployments and the Risk of Coup d’État*
Authors: Allen Michael A , Campbell Thomas , Hernandez Nicolas , Shepherd Valeryn 
Published: December 2022

Abstract
The foundation of post–WWII US foreign policy is the deployment and maintenance of a vast network of overseas military deployments. While the external security implications of these deployments are better known, scholars have spent little time connecting deployments to the internal stability threat of a coup d’état. The deployment of service members overseas creates multiple pathways to decreasing the likelihood of coup attempts by both supporting the government and its security apparatus and decreasing the benefits of a successful attempt by coup d’état conspirators. Our analysis of coups from 1951 to 2019 demonstrates that the presence of US troops decreases the likelihood of a coup.

AbstractWe report for the first time the geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas and Norwegian coast and rivers. We found that pink salmon have spread throughout the Norwegian Sea and along the Norwegian coast, and abundance increased by several orders of magnitude in 2017, with no signs that it has peaked. Marine pink salmon diet comprised mainly fish larvae, amphipods, and krill, but their relative importance varied with geographic distribution. North of 67.5°N, Amphipoda, herring, and saithe were more important, while south of 67.5°N, Euphausiidae and mesopelagic fish abounded. Pink salmon body size was larger in the northern rivers, and to the north of the Norwegian Sea and the Barents Sea, relative to the southern rivers and sea areas. Pink salmon were feeding in the ocean during the winter and spring, and in coastal areas immediately before return to the rivers, but not after they had entered the rivers. There was no geographical pattern in the seasonal timing of river ascent. The geographic pattern in abundance and diet of pink salmon, as reported here, offer a measure of the ecological effect of the invasion.
