Abstract This research explores university students’ perspectives on integrating sustainable development goals in physics education subjects (SDGs-PE). However, there is a few research that focuses on SDGs-PE. This research adopts a quantitative survey and is supported by a qualitative interview design. Fifty-two university students participated in the survey to fulfill the SDGs-PE instrument, and five interview participants for data collection. An exploratory factor analysis (EFA) and descriptive analysis were used to achieve the research’s goals. The research indicated that the SDGs-PE fulfills the criteria of validity and reliability. The construct validities of the SDGs-PE varied from .538 to .886 and explained 64.26% of the variance. Overall, the Cronbach’s alpha coefficient of the instrument was .812. This research has also highlighted the integration of physics education, education for sustainable development, and sustainable development goals.

Abstract Renewable energy penetration presents challenges for power systems, including unit reconfiguration, resource allocation, and potential electricity shortage. In Yunnan Province, where hydropower is a dominant energy source, annual power and electricity imbalance is a serious issue due to insufficient hydropower regulation capacity and less scheduling flexibility. To address these problems, a rolling dispatch method is proposed to connect medium- and long-term scheduling with short-term scheduling, providing hourly start-stop statuses and output plans for units throughout the year and effectively solving power imbalance issues. Additionally, an economic benefit and electricity shortage analysis of the Longpan leading reservoir in the Jinsha River Basin is conducted, resulting in a 13 billion kWh annual power generation increase and approximately 4 billion yuan in direct economic benefits, greatly improving Yunnan Province’s adjustment ability from dry seasons to wet seasons.

Abstract In this research, we investigate control of a hypersonic vehicle (HV) following its reentry into the Earth’s atmosphere, using deep reinforcement learning (DRL) in a continuous space. Here, we incorporate the basic kinematic and force equations of motion for a vehicle in an atmospheric flight to formulate the reentry trajectory satisfying the boundary constraints and multiple mission related process constraints. The aerodynamic model of the vehicle emulates the properties of a common aero vehicle (CAV-H), while the atmospheric model of the Earth represents a standard model based on US Standard Atmosphere 1976, with significant simplification to the planetary model. In an unpowered flight, we then control the vehicle’s trajectory by perturbing its angle of attack and bank angle to achieve the desired objective, where the control problem is based on different actor-critic frameworks that utilize neural networks (NNs) as function approximators to select and evaluate the control actions in continuous state and action spaces. First, we train the model following each of the methods, that include on-policy proximal policy approximation (PPO) and off-policy twin delayed deterministic policy gradient (TD3). From the trajectory generated, we select a nominal trajectory for each algorithm that satisfies our mission requirements based on the reward model.

Abstract As we know, the ply angle deviation of Carbon Fiber Reinforced Polymer(CFRP) reflector is difficult to obtain accurately in engineering applications, it will make thermal deformation of reflector unpredictable due to the discreteness of ply angle. In this paper, based on constitutive relationships between generalized internal force and strain of laminated composite, a novel ply angle deviation model based on normal distribution is proposed. Furthermore, an orthogonal test was designed and significance analysis were carried out by means of a 2.6m aperture reflector with polygonal back structure. Assumed that the ply angle deviation obeys normal distribution, a number of samples were further randomly generated, and the sample mean and standard deviation of the thermal deformation of reflector were calculated. According to χ2-test of goodness of fit, the thermal deformation of reflector still follows normal distribution. Finally, an example was employed to verify the validity and effectiveness of the proposed method. The results reach a good agreement with the experimental data, thus it is capable of providing a promising prospect for engineering practice.

Abstract This work’s most notable memory concept for next-generation novels was a reversible phase shift in a substance called phase change materials (PCMs). Here, a polyethylene glycol (PEG) polymer relaxation study employing DMA will be conducted to investigate the qualities of PCMs as superior materials. Through the method of wet mixing, PEG polymer with reinforcement made of silica was synthesized. The variation of silica xerogel was a composition of up to 20% silica xerogel. Adding silica is quite good in reducing the loss factor up to 50 MPa at the addition of 20% silica xerogel. This condition was due to the bonds formed in the polymer chain causing shrinkage and flexibility of composites. Due to the addition of silica xerogel as filler, we can study the relaxation behavior and loss factor of a material using DMA and learn more about its viscoelastic characteristics, including its capacity to absorb vibrations, resistance to impacts, and overall mechanical performance at various temperatures. Relaxation was frequently used to describe phase change materials (PCMs), especially when discussing their capacity to store thermal energy. The release or absorption of thermal energy by a PCM during its phase transition was referred to as the relaxation process.

Abstract In recent years, multi-energy complementation has been deepening, and the application rate of new energy sources has been increasing. A multi-timescale optimal scheduling strategy is proposed to mobilize the energy flexibility of residential integrated energy systems (RIES) and to reduce the negative impact of source-load forecast uncertainty on the scheduling plan. Firstly, for the energy supply structure of RIES, the operation constraint model of each energy hub equipment is established. Then, the optimal scheduling is divided into three stages: day-ahead planning, intra-day planning, and real-time planning, each of which will consider the volatility of source-load prediction and determine the operation status of the equipment according to its importance level. The experimental results show that the proposed multi-timescale scheduling strategy can ensure the economy while minimizing the deviation of the main grid power purchase in the real-time and day-ahead phases, providing a basis for the development of new energy capacity in the grid to grow to higher penetration rates.

Abstract As the structure of existing anti-power attack circuits has certain security problems, this paper proposes a new mask-based control constant power logic circuit based on the existing masking technology. By integrating OR/NOR and AND/NAND circuits into a dual-rail circuit, different circuit logic functions can be controlled by inputting different masks. By introducing two parameters, Normalised Energy Deviation (NED) and Normalised Standard Deviation (NSD), the structure proposed in this paper improves the level of resistance of the circuit to power attacks to a certain extent, as well as reduces the cost of the circuit compared to other power attack resistant circuits.

Abstract Multi-pedestrian tracking is one of the hot topics in computer vision. For an intelligent mobile robot, multi-pedestrian tracking from a first-person perspective can provide information for navigating through a crowd and ensure safety. Most of the existing methods cannot deal with occlusion and trajectory overlap well. In this paper, a multi-pedestrian tracking method fusing two-stage matching is proposed. Firstly, the detection and the corresponding feature values of the pedestrians are obtained by a multi-task learning network based on CenterNet. Then the detected pedestrians are matched with feature values by greedy strategy. When dealing with the reappearance of pedestrians caused by occlusion or trajectory overlap, the sample database is established to update the samples in real time. The color histogram and HOG feature are calculated for each sample. When the pedestrian disappears, the direction of disappearance and the last position is recorded for the selection of trajectory. Finally, the KM algorithm is used for cross-frame matching. Our method is compared with some recent methods on MOT data sets. The result shows that our method has a significant improvement in the main evaluation index MOTA.
