Discussion of Third Harmonic Voltage Characteristics of Large Hydro Generator Stator Winding and Improvement of Ground Protection
Authors: Tan Liming , Wang Yikai , Feng Xiaosong , Zhang Chunhui , Yin Xianggen 
Published: April 2022

Abstract
Large hydro-generators require a 100% protected area for stator ground protection. Because the fundamental voltage criterion has low sensitivity near the neutral point, a high sensitivity third harmonic voltage criterion is needed to ensure that the generator can accurately respond to stator ground fault. This paper analyzes the third harmonic voltage characteristics of two large hydro-generators, calculates the sensitivity of the existing third harmonic criterion, and points out that the impedance parameters of the grounding transformer should be considered. In view of the lack of sensitivity of the third harmonic criterion for large hydro-generators, this paper proposes a stator ground protection criterion based on the third harmonic voltage variation, which has zero action quantity under the generator non-fault conditions and zero braking quantity after a ground fault occurs, and thus has high sensitivity and can effectively respond to high-resistance ground faults. PSCAD/EMTDC simulation results show that the proposed method has high sensitivity at different fault locations and transition resistances, which can provide theoretical support for the improvement of stator grounding protection in practical engineering.

Published: April 2022

Abstract
Aiming at the problems of complex time-consuming and heavy data processing workload in the field test of commercial vehicle handling stability, a vehicle handling stability test solution based on virtual instrument technology is proposed. This solution is based on the existing test equipment and conditions, using LABVIEW virtual instrument, integrated application of GPS, AHRS and steering force angle tester to form a set of road test system solutions that can realize vehicle handling and stability. The system can meet the requirements of the national standard Controllability and Stability Test Procedure for Automobile (GB / T 6323-2014) to realize the vehicle handling stability test, and the system test is verified by the real vehicle test data, which provides a more efficient and convenient test method for the study of vehicle handling stability test.

Published: April 2022

Abstract
Consensus protocol is suggested for target following of two non-holonomic robots. For moving robot platform, the computer that acts as the controller, and the robots to establish wireless local area network (WLAN), the remote control of the robot is achieved by transmitting data through cordless communication. Kinematics mathematical modelling and pose error model of the moving automaton are raised, applying consensus protocol to implement trajectory tracking. Emulation effects demonstrate that the suggested control way is feasible.
Entanglement dynamics of thermofield double states in integrable models
Authors: Lagnese Gianluca , Calabrese Pasquale , Piroli Lorenzo 
Published: April 2022

Abstract
We study the entanglement dynamics of thermofield double (TFD) states in integrable spin chains and quantum field theories. We show that, for a natural choice of the Hamiltonian eigenbasis, the TFD evolution may be interpreted as a quantum quench from an initial state which is low-entangled in the real-space representation and displays a simple quasiparticle structure. Based on a semiclassical picture analogous to the one developed for standard quantum quenches, we conjecture a formula for the entanglement dynamics, which is valid for both discrete and continuous integrable field theories, and expected to be exact in the scaling limit of large space and time scales. We test our conjecture in two prototypical examples of integrable spin chains, where numerical tests are possible. First, in the XY-model, we compare our predictions with exact results obtained by mapping the system to free fermions, finding excellent agreement. Second, we test our conjecture in the interacting XXZ Heisenberg model, against numerical iTEBD calculations. For the latter, we generally find good agreement, although, for some range of the system parameters and within the accessible simulation times, some small discrepancies are visible, which we attribute to finite-time effects.

Published: April 2022

Abstract
Laser scanners are gaining acceptance as a tool for three-dimensional modelling of existing buildings, but not much more than that. The idea that a digital model constructed from hundreds of thousands of measured laser points having ‘soulful’ applications remains foreign to Architects. This paper presents the work that has been ongoing for over 5 years at the School of Architecture at Victoria University of Wellington in New Zealand and the ‘soulful’ experiences we have encountered in that work.
Sustainability for whom? Cities and buildings through the lens of older people
Authors: Soebarto V 
Published: April 2022

Abstract
As we move towards larger and more complex urban developments and with increasing occurrences of extreme weather resulting in significant environmental, societal and economic impacts, it is no longer a question that cities around the world must aim for sustainability. The past few decades have seen efforts by many countries to tackle these critical issues. At the same time, many countries also face significant demographic changes, with almost a quarter of their population over 65 years will be ageing in place, in their own homes. Yet cities, particularly our inner-city built environments, are spaces that are usually imagined, planned and structured for a younger, working-age demographic. This paper discusses the current gap in knowledge in addressing sustainability of our cities and buildings, and proposes a new way of engaging people who are often forgotten, yet they have many years of experience and wisdom about how to live sustainably: the older people. Two examples of ongoing research with older ‘citizen scientists’ are presented. Both cases demonstrate that it is critical to consider cities and buildings from the eyes of older people in society.

Published: April 2022

Abstract
This study aims to develop a new device, “cross-wind catcher”, for mid-to-high-rise affordable apartments for improving the ventilation performance in the tropics, where the natural ventilation is considered essential. We conducted a primary simulation study to find optimum wind catchers, followed by a field experiment using a full-scale experimental building to confirm the effects of the proposed device. The results showed that the proposed cross-wind catcher was able to increase the ACH by approximately 1.2 to 1.4 times compared with the control unit.

Published: April 2022

Abstract
Various forms of quarantine and social restrictions to prevent the spread of the COVID-19 pandemic has impacted lifestyle. WFH has emerged as a growing trend in this new normal era. The implementation of WFH results in all work-related activities becoming home-centred. This study aims to analyse the pheasant and find out the effect of household appliance use on energy consumption during the implementation of WFH. The questionnaire survey was conducted in April 2020 and it collected 215 responses from residents of Indonesia, during the pandemic which was distributed online. The data were analysed using a multiple regression analysis with SPSS to determine the relationship between variables. The results showed that the length of WFH time affected an increase of energy consumption especially from the use of home computer, internet, rice cooker, AC, and water needs. In addition, the increase that happened also depends on the population living and the size of the building they live in. If this continues, it could lead to the risk of an energy crisis. Strategies related to proper distribution and energy demand are needed to build resilience and form a sustainable society.

Published: April 2022

Abstract
Thermal and visual comfort are important elements in the learning process. The object chosen was the classroom of the Sawah Besar 01 public elementary school, Semarang where the building tends to have a homogeneous facade design but with openings that have varying orientation directions. This affects the level of comfort both thermal and visual in the classroom. Data analysis was carried out quantitatively, namely to obtain a thermal comfort index and natural lighting comfort index according to the Indonesia National Standard. The thermal comfort conditions of all selected rooms on the 1st and 2nd floors did not meet the comfortable thermal comfort standard for classrooms. Rooms 1 and 2 on the 1st floor tend to be above the minimum level of classroom lighting. Room 3 on the 2nd floor tends to be stable and all of them are above the minimum limit. In room 4 on the 2nd floor, the general lighting level has exceeded the minimum limit. New façade opening designs and mechanical ventilation aids need to be applied to improve thermal and visual comfort according to the Indonesia National Standard.

Abstract
The synergy between environmental sustainability and technological progress is the key to sustainable development. The dependence of the people of the Giri Kingdom on the Pegat Lake as a source of clean water as well as the orientation centre of the Giri Kingdom’s downtown area, has shifted due to the development of the city and advances in clean water technology. The potential for socio-cultural sustainability which is based on the existence of Pegat Lake is the strength of the meaning of local wisdom which is a process of harmonious relationship between nature, humans and architecture is starting to be forgotten. This paper explores the role of Pegat Lake from time to time based on artefacts, data and history as well as notes on the results of previous research. The important finding of interdependence between the Pegat Lake area, the Giri Palace area and the Tomb and Ainul Yaqin Mosque area is a strength of sustainability to continue to be developed according to the socio-cultural demands of the community as well as the development of religious and historical-based ecotourism as an answer to sustainable regional development.

AbstractThe rehabilitation of substandard housing (Rumah Tidak Layak Huni or RTLH) program is an effort of both central and local governments to provide decent housing for the low-income community. Over the past four years, Plandi Village has received substandard housing rehabilitation grants in the form of building materials and cash. This research will describe the physical and non-physical benefits felt by the beneficiaries using a qualitative descriptive method based on interviews, literature studies, and related documents. The results show that the beneficiaries can experience physical benefits in the form of a house that is suitable for habitation which is sturdy and healthy in providing enough light and sanitation as well as a standardized building floor area. Meanwhile, the non-physical benefits obtained are improved and more functional space to carry out daily activities in the house, even increasing their social status.
Housing challenges in sinking coastal city: rethinking urban housing in subsidence area for a more resilient community
Authors: Hamdani R S , Hadi S P , Rudiarto I 
Published: April 2022

Abstract
Housing in coastal cities is facing complex environmental hazards. The risk of being permanently submerged caused by sea level rise-related flooding is aggravated by the localized hazards, which is land subsidence. We explored the land subsidence conditions in the housing zone of Semarang City using overlay spatial analysis, and we expand the discussion to the regulatory aspect and local adaptation through content analysis. We found that challenges in housing zone are the severe subsidence that is occurring on dense housing zone, regulation that still less sensitive towards incorporating the slow onset disaster and not properly provided housing hydrological consideration nor the water provision, and poor drainage system as well as limited adaptation capacity that makes people lives in a false harmony of being resilient. Affordable alternative housing such as stilt house and drainage infrastructure improvement as well as detailing and reframing building regulation that is adequate to address both subsidence and flooding is undeniably important to ensure the adequate housing is accessible for all coastal city residents.

Published: April 2022

Abstract
Indonesia has a high risk of earthquake and tsunami disasters, especially in areas around the long and relatively sloping coastline. Nanggroe Aceh Darussalam as an area that has been hit by an earthquake and tsunami, in its development of settlements it is more directed to disaster-prone areas in coastal areas. This study aims to identify the development of housing after rehabilitation and reconstruction due to the earthquake and tsunami in the Gampong Pande area, in the context of mitigating earthquake and tsunami disasters in the future. This research is related to ethnographic research that uses an emic approach in field surveys, emphasizes the natural setting context, focuses on interpretation and meaning, involves the community deeply, and focuses on contemporary phenomena as a whole. Post-disaster mitigation actions carried out in residential development are structural modifications referring to and in line with the Building Code. Post-disaster mitigation actions carried out in the development of residential areas are land grants for road widening as an evacuation route during disasters and the construction of sea dikes to reduce tidal waves of sea water entering settlements and planting mangroves along the sea wall as a green belt that doubles as a green belt and source of fishermen’s economy.

Abstract
The demand for office building for the sports branch of martial arts in Indonesia has increasingly risen in line with the rapid development of the international arena. For the administrative region, including the province of East Java, a martial arts head office is essential the administrative duties and management of the sports organisation. A martial arts office is an office to accommodate administrative and management tasks. It also requires facilities for users who mostly have an athletic background and are physically fit and well-being. Therefore, this paper aims to explore and propose architectural designs of martial arts’ administrative office from finding the idea, determining the design’s parameters and concept to formal design transformation. Presenting big ideas by translating the character and value of sport is applied during the design process and considering the green design approach to provide building’s energy-efficient. The result proposes a building design that expresses the dynamicity of sport’s value and characters. The building is also designed by reducing negative impacts on the environment and maximise energy saving.
Shape exploration through airflow simulation for reducing dust in apartment design
Authors: Maharani R T , Ekasiwi S N N , Samodra FX T B 
Published: April 2022

Abstract
Dust is a particle in the air which at certain concentrations can be harmful to human health. Therefore, in designing buildings, we need to consider forms that can reduce dust exposure. The design process, which uses a force-based framework, was carried out to design an apartment located in a very dusty industrial area. Shape exploration is done using simulation software. The process of exploring the basic form of an apartment with a courtyard type is realized by forming a surface that is easy to flow through by wind, namely by making a sloping surface, so that the wind easily removes dust, so it does not enter the room.
Study on non-equilibrium solidification microstructure of Al–Cu3–Si–Mg alloy by MMDF
Authors: Wu Tong , Xing Shuming , Liu Xin 
Published: April 2022

Abstract
Al–Cu3–Si–Mg wheel hubs were prepared by molten metals die forging (MMDF). The as-cast microstructure morphology of the alloy formed under pressure was observed by optical microscope and scanning electron microscope. The granular phases θ (Al2Cu) were distributed in the α–Al grains, and the cross phases β (Mg2Si) grew near the grain boundary in the α–Al grains. Polygonal compounds φ (AlxTi9La2Ce6Cu) and irregular eutectic structures mainly formed by (α + Al2Cu) eutectic formed under non-equilibrium solidification were found at the grain boundaries. Q (Al5Cu2Mg8Si6) phases were found at the intersection of grain boundaries. With the increase of pressure, the proportion of irregular eutectic structures (α + Al2Cu) decreased from 7.3% to 5.2%. Combined with microstructure analysis and thermodynamic software analysis, the non-equilibrium solidification path was determined as follows: L → L + φ → L + α + φ → L + (α + e) + α + φ → (α + e) + Q + α + φ → (α + e) + Q + [α + θ] + φ → (α + e) + Q + [α + θ + β] + φ
Wear mechanism of Nomex/PTFE fiber reinforced composites
Authors: Jian Liu , Fei Lu , Tiantian He , Xianjuan Pang , Yongzhen Zhang 
Published: April 2022

Abstract
This paper is aimed at the problems of abnormal tribological damage and fluctuation of tribological performance in the self-lubricating composite serving in heavy load spherical plain bearing in aerospace field. The Nomex/PTFE fiber reinforced composite was used to carry out a reciprocating block on ring tribological test, investigating the tribological performance of the material and its wear evolution. Results show that the influence of oscillating frequency on material wear is obviously higher than that of load under high load condition (more than 90 MPa or 180 kN). Under a certain load and frequency condition, friction temperature is a key factor to affect wear behavior of the material. Friction heat plays a dominant role in the process of worn out failure of the material. Too high friction temperature greatly weakens the friction and wear performance, resulting in material failure in a short time. Thermal fatigue is the main tribological damage mode of the material under the high load and high frequency condition, with local worn out occurred. This finding was also verified by SEM analysis of the worn surface and wear debris.
Enhanced damping and thermal conductivity of hBN/silicone rubber composites via strong interfacial action
Authors: Ren Fengmei , Yang Zizheng , Ma Haihong , Zhou Zhengfa , Xu Weibing 
Published: April 2022

Abstract
High integration and miniaturization of electronic systems require thermal conductivity and mechanical damping materials. In this study, hexagonal boron nitride (hBN) particles were modified by vinyltrimethoxysilane (V171) and hexadecyltrimethoxysilane (N3116) for comparing, and described as V171-hBN and N3116-hBN, respectively. The pristine and surface modified hBN were filled in vinylmethylpolysiloxane (VMQ), and then vulcanized to fabricate hBN/silicone rubber composites. The damping properties of V171-hBN/silicone rubber composites were significantly higher than that of pristine hBN/silicone rubber composites, while N3116-hBN/silicone rubber composites were in contrast. The strong interfacial action in V171-hBN/silicone rubber composites came from the chemical bond by vinyl groups on the surface of V171-hBN taking part in the vulcanization of VMQ. This strong interfacial action led the deformation of hBN, and the internal friction between layers of hBN significantly increased to dissipate more energy. As a result, V171-hBN/silicone rubber composites with excellent damping and thermal conductivity as well as good mechanical properties were obtained.
Aggregation sheaves for greedy modal decompositions
Authors: Robinson Michael 
Published: April 2022

Abstract
This article develops a new theoretical basis for decomposing signals that are formed by the linear superposition of a finite number of modes. Each mode depends linearly on the weights within the superposition and nonlinearly upon several other parameters. The particular focus of this article is upon finding both the weights and the parameters when the number of modes is not known in advance. This article introduces a novel mathematical formalism, aggregation sheaves, and shows how they characterize the behavior of greedy algorithms that attempt to solve modal decomposition problems. It is shown that minimizing the local consistency radius within the aggregation sheaf is guaranteed to solve all modal decomposition problems. Since the modes may or may not be well-separated, a greedy algorithm that identifies the most distinct modes first may not work reliably.
