A quick-response and high-precision dynamic measurement method with application on small-angle measurement

Published: November 2021

Abstract
Small-angle measurement tools with pendulum mechanical structure face two major challenges. One is that it takes a long time to wait for the pendulum structure to completely stop swinging, and the other is that the instrument has poor anti-interference ability. Inspired by the two challenges, in this paper we propose a dynamical measurement method to achieve a fast and accurate measurement synchronously. Specifically, a damped oscillation modeling of the pendulum with nonlinear least-squares fitting is presented to estimate the model parameters, which includes the angle of the oblique plane. In addition, it is proved that the minimum sample size required for data fitting is decided by one oscillation period, which guarantees the shortest measuring time within high precision. Moreover, in this paper we also present the precision criterion of fitting parameters to judge whether the fitting results meet the requirements. This proposed method is applied to a developed small-angle measurement tool. The error of the proposed measurement system is better than

3.25

′
′

and the uncertainty is

4.8

′
′

within a measurement angle of

′

, and the settling time is 0.45 s. The experimental results confirm that this method can not only greatly shorten the measuring time, but enhance the anti-interference ability and realize high-precision measurement.
MEAM interatomic potentials of Ni, Re, and Ni–Re alloys for atomistic fracture simulations
Authors: Alam Masud , Lymperakis Liverios , Groh Sébastien , Neugebauer Jörg 
Published: November 2021

Abstract
Second nearest neighbor modified embedded atom method (2NN-MEAM) interatomic potentials are developed for the Ni, Re, and Ni–Re binaries. To construct the potentials, density functional theory (DFT) calculations have been employed to calculate fundamental physical properties that play a dominant role in fracture. The potentials are validated to accurately reproduce material properties that correlate with material’s fracture behavior. The thus constructed potentials were applied to perform large scale simulations of mode I fracture in Ni and Ni–Re binaries with low Re content. Substitutional Re did not alter the ductile nature of crack propagation, though it resulted in a monotonous increase of the critical stress intensity factor with Re content.

Published: November 2021

Abstract
In this work, two silicon nanostructures were doped into polymer/nematic liquid crystal composites to regulate the electric-optical performance. Commercial SiO2 nanoparticles and synthesized thiol polyhedral oligomeric silsesquioxane (POSS-SH) were chosen as the dopants to afford the silicon nanostructures. SiO2 nanoparticles were physically dispersed in the composites and the nanostructure from POSS-SH was implanted into the polymer matrix of the composites via photoinduced thiol-ene crosslinking. Scanning electron microscopy results indicated that the implantation of POSS microstructure into the polymer matrix was conducive to obtaining the uniform porous polymer microstructures in the composites while the introduction of SiO2 nanoparticles led to the loose and heterogeneous polymer morphologies. The electric-optical performance test results also demonstrated that the electric-optical performance regulation effect of POSS microstructure was more obvious than that of SiO2 nanoparticles. The driving voltage was reduced by almost 80% if the concentration of POSS-SH in the composite was nearly 8 wt% and the sample could be completely driven by the electric field whose voltage was lower than the safe voltage for continuous contact (24 V). This work could provide a creative approach for the regulation of electric-optical performance for polymer/nematic liquid crystal composites and the fabrication of low voltage-driven PDLC films for smart windows.
Mixing and observation for Markov operator cocycles*
Authors: Nakamura Fumihiko , Nakano Yushi , Toyokawa Hisayoshi 
Published: November 2021

Abstract
We consider generalized definitions of mixing and exactness for random dynamical systems in terms of Markov operator cocycles. We first give six fundamental definitions of mixing for Markov operator cocycles in view of observations of the randomness in environments, and reduce them into two different groups. Secondly, we give the definition of exactness for Markov operator cocycles and show that Lin’s criterion for exactness can be naturally extended to the case of Markov operator cocycles. Finally, in the class of asymptotically periodic Markov operator cocycles, we show the Lasota–Mackey type equivalence between mixing, exactness and asymptotic stability.
Ultrasonic guided wave-based debond identification in a GFRP plate with L-stiffener

Published: November 2021

Abstract
This paper presents a robust assessment of debond in a glass fibre-reinforced polymer composite structure with L-stiffener attachment. Towards this, the ultrasonic guided wave (GW) propagation based laboratory experiments have been carried out on a stiffened composite panel with piezoelectric transducers for the excitation of GWs and a scanning laser Doppler vibrometer for sensing the GW propagation. To study the changes caused by the stiffener and debond a signal processing based multi-point analysis has been carried out. The proposed methodology consists of two steps. Step 1 using the full wavefield root mean square energy map-based approach to check the presence of debond. Step 2 using point-wise measurements to study debond localization and size estimation using a baseline free signal coefficient difference algorithm (SCDA). The proposed processing approaches are applied for an in-depth analysis of the experimental signals that provide information about the interaction of GWs with stiffener and debond. The mentioned approaches take advantage of the asymmetry caused by the damage. For the applied SCDA methodology there is no need for full-wavefield measurements, healthy case measurements, as only a few measurement points can be enough for the assessment of stiffener debond in such structures.
CanariCam Mid-infrared Drift Scanning: Improved Sensitivity and Spatial Resolution
Authors: Torres-Quijano Amílcar R. , Packham Christopher , Fernandez Acosta Sergio 
Published: November 2021

Abstract
Ground-based mid-infrared (MIR) astronomical observations require the removal of the fast time variable components of (a) sky/background variation and (b) array background. Typically, this has been achieved through oscillating the telescope’s secondary mirror a few times a second, a process termed “chopping.” However, chopping reduces on-object photon collection time, imposes stringent demands on the secondary mirror, requires nodding of the telescope to remove the radiative offset imprinted by the chopping, and relies on an often-fixed chop-frequency regardless of the sky conditions in the actual observations. In the 30 m telescope era, secondary mirror chopping is impracticable. However, if the sky and background are sufficiently stable, drift scanning holds the promise to remove the necessity of chopping. In this paper, we report our encouraging drift scanning results using the CanariCam MIR instrument on the 10.4 m Gran Telescopio Canarias and the implications to future instruments and experiments.

Published: November 2021

Abstract
To support the scenario design for the upcoming long-pulse high-performance campaign of Wendelstein 7-X, this work presents a study of high-beta full-field 3D equilibria obtained with the HINT code. For three magnetic configurations of different edge-ι, the effects of both overall pressure and pressure profile changes on the magnetic topology are analyzed. Anisotropic diffusion modeling is used to obtain estimates of the conductive heat load distribution both on the divertor and other plasma-facing components in finite-beta magnetic configurations. For the magnetic standard configuration, limitations of the model are outlined by comparing measured and predicted heatloads by performing a linear regression of the main strike-line position against various plasma parameters in both the experimental and the simulated device.
Post-thermal-quench shattered pellet injection for runaway electron seed depletion in ITER
Authors: Nardon E. , Matsuyama A. , Hu D. , Wieschollek F. 
Published: November 2021

Abstract
The possibility of using shattered pellet injection after the thermal quench of an ITER disruption in order to deplete runaway electron (RE) seeds before they can substantially avalanche is studied. Analytical and numerical estimates of the required injection rate for shards to be able to penetrate into the forming RE beam and stop REs are given. How much material could be assimilated before the current quench (CQ) becomes too short is also estimated. It appears that, if hydrogen pellets were used, the required number of pellets to be injected during the CQ would be prohibitive, at least considering the present design of the ITER disruption mitigation system (DMS). For neon or argon, the required number of pellets, although large, might be within reach of the ITER DMS, but the assimilated fraction would have to be very small in order not to shorten the CQ excessively. This study suggests that other injection schemes, based for example on small tungsten pellets coated with a low Z material, may be worth exploring as an option for an upgrade of the ITER DMS.

Abstract
Indonesia is a country that has great potential for disaster. A major earthquake hit the Special Region of Yogyakarta, especially Bantul Regency, in 2006. This has demanded the establishment of a disaster-safe school that is ready to anticipate disasters. Disaster-safe school students need to be fully prepared in various aspects, including physical aspect. Therefore, this study aims to determine the increase in physical fitness before and after carrying out game-based physical activities for upper grade students in a Disaster-Safe School. This study adopted an experimental method that involved one group pre-test-post-test design. Participants were upper grade students (grade 4 to 5) in Madrasah Ibtidaiyah Negeri 2 Bantul, totaling 74 people under such criteria as aged 10 to 12 years and following the complete treatment. The instrument used was the Indonesian Physical Fitness Test (IPFT) for children aged 10-12 years. Data analysis using paired sample t-test. The results showed that there was an increase in the physical fitness of students after being given treatment in the form of game-based physical activity for 12 meetings. Good physical fitness is a form of physical preparedness in facing various emergencies including disasters. The better physical fitness level of students, the more physically prepared they will be when facing disasters.

Authors: Indayani M , Trisutomo S , Ramli M 
Published: November 2021

Abstract
The increasing number of disasters happening in cities has put the sustainability of urban life at stake. One of the measures to strengthen the community's resilience is by understanding how they got attached to the place they live. However, the findings of the previous research regarding the influence of place attachment to community resilience show dissimilarities. This research aims to further reveal the influence of place attachment to communities’ resilience in urban areas with a variety of socio-demographic and social dynamics. The study was conducted to 323 households that have frequently been affected by flood, at an urban-village, Tallo sub district, of Makassar City, Indonesia. With simple linear regression analysis, the aspects of place attachment which are personal, social, physical, and cultural are measured to assess its influence on each of their resilience perceptions. The research revealed that there is a positive influence of place attachment to a communities’ resilience. Based on the communities’ response, it can be seen that resilience is more likely to be formed by social-community aspects.

Authors: Syarafina A Z , Sumunar D R S 
Published: November 2021

Abstract
Merapi Vulcano is one of the most active volcanoes in the world. This volcano has a secondary hazard that is lahar flow. This research refers to the 2010 eruption of Merapi Vulcano in Indonesia. Eventhough there was a phreatic eruption in 2018, it did not increase the deposition of lahar material on its slopes. The communities living along the lahar prone rivers have various vulnerabilities including physical, social, economic and environmental vulnerability. This research aims to determine the physical vulnerability distribution of settlement in lahar hazard prone areas alongside Pabelan River. This study is a descriptive quantitative research using secondary data and spatial analysis. The results of this research show that the high vulnerability distribution covers the area of Mungkid Sub-district and Sawangan Sub-district as many as 5 clusters or equal to 7.49% of the research area. The medium level of physical vulnerability is Dukun Sub-district, Mungkid Sub-district and Muntilan Sub-district as many as 26 clusters or equal to 41.27% of the research area. The low physical vulnerability of settlements is scattered in Dukun Sub-district, Mungkid Sub-district, Muntilan Sub-district and Sawangan Sub-district as much as 32 clusters or equal to 50.79% of the research area. It can be concluded that the physical vulnerability of settlements in lahar hazar prone along the Pabelan river after the 2010 eruption of Merapi Vulcano is dominated by low vulnerability.

Authors: Arifah Dinda Zannuba , Supriatna S. 
Published: November 2021

Abstract
Indonesia is a country located between three tectonic plates. It is the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate. The location caused Indonesia to be prone to disasters caused by the movement of plates, one of which was a tsunami. Tsunamis are high waves that hit ports or beaches. Relatively sloping beaches with low beaches can cause larger tsunami waves. This study was carried out on the coastal of Ujung Genteng, Sukabumi. The purpose of this study is to analysis the area of tsunami exposure that occurred on the coast of Ujung Genteng. GIS-based spatial modelling is used to combine different types of data, both spatial and non-spatial data to be processed into tsunami exposure area information. Modelling of the inundation was carried out with mathematical calculations developed by Berryman (2006). By modeling the tsunami with a worst-case scenario of wave height of 20 meters, it was obtained that the tsunami exposed area reached 663.29 Ha. The area belongs to a low hazard class of 2.59 Ha, a medium hazard class of 29.05 Ha, and an area that belongs to a high hazard class of 631.65 Ha. The results of this modeling are expected to be a reference for tsunami disaster mitigation planning in Ujung Genteng.
