“…[7] The value of dielectric constant depends on the various factors such as synthesis route, temperature, frequency, and dopants. [8] Doped and undoped barium titanate can be prepared by various methods-solidstate reaction method, [9] hydrothermal method, [10,11] sol-gel processing, [12,13] solvothermal method, [14] chemical coprecipitation method, [15] etc. The method of synthesis of ceramic shows an important effect on its microstructure, which directly affects its performance.…”

In this work, a series of BaTi 1−x Mn x O 3 -polyimide films were prepared by simple solution casting method. For the preparation of composite films firstly, manganese doped barium titanate, BaTi 1−x Mn x O 3 (where x = 0.00, 0.01, 0.03, 0.05) was synthesized by sol-gel process. The effect of Mn doping on its structural and dielectric properties was nicely explained. The highest dielectric constant value of 7,104 was obtained for BaTi 0.99 Mn 0.01 O 3 (BTMn) nanoparticles with low dielectric loss value 2.44. It was observed that Mn-doping concentration on barium titanate influences its crystal structure. Improved dielectric properties were reported for nanocomposite thin films containing BaTi 0.99 Mn 0.01 O 3 and polyimide (PI). A series of five homogeneous nanocomposite films were successfully prepared and were characterized thoroughly. The dielectric properties were studied as a function of frequency and loading percentage of BTMn in PI. The dielectric constant of the BTMn/PI nanocomposite films increased from 3.23 to 8.63 with the increase in loading percentage of ceramic from 0 to 5 wt%, respectively. The nanocomposite films were flexible with good mechanical properties and the flexibility decreased with increase in loading percentage of BTMn. The films showed high thermal stability in nitrogen atmosphere up to 571°C with 10% weight loss and also exhibited high glass transition temperature up to 337°C.

“…Li Tiancheng et al established a fan grid map model based on polar coordinate system, which can effectively solve the problem of circular wave propagation algorithm [3]. Guo Lijin et al proposed an adaptive raster map creation algorithm based on quadtree to solve the problem that different raster sizes greatly affect the accuracy and effect [4]. Under the condition of the same accuracy, the algorithm can effectively reduce the amount of data storage and computation, and improve the real-time performance.…”

In view of the problems existing in the path planning algorithms of unmanned vehicles, such as low search efficiency, slow convergence speed and easy to fall into the local optimal. Based on the characteristics of route planning for unmanned vehicles, this paper introduces Q-Learning into the traditional ant colony algorithm to enhance the learning ability of the algorithm in dynamic environment, so as to improve the overall efficiency of route search. By mapping pheromones into Q values in Q-learning, rapid search in complex environments is realized, and a collection-free path satisfying constraints is quickly found. The results of case analysis show that compared with the traditional ant colony algorithm and the improved ant colony algorithm considering reward and punishment factors, the improved ant colony algorithm based on Q-Learning can effectively reduce the number of iterations, shorten the path optimization time and path length and other performance indicators, and has many advantages in jumping out of the local optimal, improving the global search ability and improving the convergence speed, and has good adaptability and robustness in complex environments. It ensures the safety and stability of unmanned vehicles in complex environments.

“…This means that EM resembles a "black-box" approach in which pure mass spectra are extracted independently without any discrimination (chemical compounds or background). At present, EM approach has been applied to analyze signals of FTIR, 20,21 UV, 22 MS, 18 Raman, 23,24 and NMR 25,26 spectral data with success. More importantly, the uniqueness of the EM approach allows it to accurately identify and quantify target analytes in complex mixtures or those that are embedded in the chromatographic background.…”

Gas chromatography‐mass spectrometry (GC‐MS) is an important analytical technique for the analysis of organophosphorus pesticides in food products. Because of the complex matrices of food products, multiple preprocessing steps are required prior to performing the GC‐MS analysis. Despite that, it is difficult to totally eliminate the interference of complex matrix background. In this work, we introduce an entropy minimization technique that can eliminate the need for comprehensive preprocessing steps to detect organophosphorus pesticides in a fortified orange juice sample. The pure mass spectra and extracted‐ion chromatograms of the pesticides were extracted and reconstructed. The results achieved higher National Institute of Standard and Technology (NIST) match scores in comparison to the conventional background subtraction technique. Taken together, the entropy minimization technique is capable of providing rapid qualitative and quantitative analyses of complex GC‐MS data. This technique is expected to have great potential for natural products and food analysis applications.
