In this paper, we proposed a novel hybrid quantum dot emitting layer (QD EML) for the efficient quantum dot light-emitting diodes (QLEDs). This proposed hybrid emitting layer consisted of a composite polymer with poly (9-vinlycarbazole) (PVK) and 1,3-bis[(4-tert-butylphenyl)-1,3,4oxadiazolyl]phenylene (OXD-7) in the weight ratio of 7:3 and high quantum yield CdSe@ZnS/ZnS quantum dots. By using PVK as hole transport and OXD-7 as electron transport polymer, both hole and electron was supported to inject into QD efficiently. Consequently, the maximum current efficiencies of 7.9 cd/A was achieved in QLEDs with the hybrid EML, which was $sim 250$ % improvement over the bared EML-device. Moreover, high color purity and wavelength stable green QLEDs with peak wavelength of 536 nm was also obtained.

Rapid prototyping has been the up-and-coming technology to replace traditional manufacturing processes for several decades. However, the cost of producing a rapid prototyping machine that’s able to create a model using metal is too high to apply to low volume production. Therefore, one of the focal points of rapid prototyping is producing patterns for investment casting processes, called rapid casting. Fused deposition modelling (FDM) is a rapid prototyping process which forms a part by continuously melts plastic filaments such as ABS and PLA layer by layer. FDM is a method frequently used in rapid casting. There are two main problems with rapid casting, the cracking of mould shells during the burnout process and patterns incompletely burns out, leaving residual ash and releases corrosive by-products which affect the shells. In this study, we use three parameters to determine their effects on the amount of residual ash the patterns leave behind: Number of perimeters shells, infill percentage and infill pattern. ABS patterns fabricated using FDM method are used because ABS has considerably higher burnout temperature amd is used more frequently in industrial processes, previous studies have also shown that semi-hollow ABS plastic patterns have better dimensional accuracy and surface roughness compared to PLA plastic patterns. After that, we trained an Artificial neural network (ANN) and let it predict the outcomes of the same experiments and compared the results to that of Taguchi’s method predictions using the mean absolute percentage error (MAPE). The results indicate that the predicted outputs of the ANN are very close to the expected output with high reliability (95.218%). ANN method also has a lower MAPE than Taguchi’s method, highlighting that ANN method is a reliable alternative method to accurately predict the relationship between the chosen parameters and the results.

In this paper, a method for navigation of self-driving vehicles is proposed. Although the research for this problem has been performed for several years, we noticed that the elevated accuracy results have not been achieved yet. Therefore, the method using a convolutional neural network (CNN) for training and simulation of unmanned vehicle model on the UDACITY platform has been made. Details, we used three cameras mounted in front of a vehicle to follow three directions were left, right and center position to collect data. The data are the images that captured from three cameras. The number of samples image is 15504. In this research, the label with two parameters are the steering angle and speed from each image would also be created. After collecting the data, these parameters will be achieved by training CNN used to navigate the vehicle. With the combination of three cameras, the accuracy of this navigation task is improved significantly. When vehicle deviates to the left, we will compute the error of the steering angle value between the middle and left position. Afterward, the steering angle value will be adjusted to control the vehicle could run in the center of the lane. Similarly, in the case when vehicles deviate to the right. Based on the simulation platform of UDACITY, we simulated and obtained the result with accuracy was 98, 23%.

High-performance fiber-reinforced concretes (HPFRCs), including ultra-high-performance fiber-reinforced concretes (UHPFRCs) refers to smart construction materials those can monitor themselves by determining their electrical resistivity under loading, i.e., the electrical resistivity importantly governs the such smart property of HPFRCs. In this research work, the influences of environmental condition on the electrical resistivity of HPFRCs were experimentally reported. The electrical resistivities of HPFRCs were measured under controlled temperature and relative humidity using a chamber machine. As the temperature or relative humidity increased, the electrical resistivity of the studied HPFRCs clearly decreased. The electrical resistivities of cement-based composites were generally dependent much upon temperature and relative humidity.

Tra catfish (Pangasianodon hypophthalmus) is widely cultivated in the Mekong Delta Region, Vietnam, with mainly production of frozen fillets. Crude oil was extracted from tra catfish fat, a by-product, by hot water. Crude oil has phosphorus content of 18.1 mg/kg, Abs $_{mathbf {228nm}}$of 1.07, melting and solidification points of 33.8$^{mathbf {o}}textbf{C}$ and 24$^{mathbf {o}}textbf{C}$, respectively. After treatment stages (degumming using citric acid, neutralization, winterization, dewaxing, bleaching using activated carbon and deodorization), chemical and physical properties of refined oil have many advantaged changes. Respectively, phosphorus content, Abs$_{mathbf {228nm}}$, melting and solidification points were reduced to 3.84 mg/kg, 0.52, $10.2 ^{circ}mathrm {C}$ and $- 2.0 ^{circ}mathrm {C}$. Besides, quality parameters such as peroxide value (2.66 m.eq/kg), iodine value (66.85 g/100g), and saponification value (152 mg KOH/g) were analytical measurements. Moreover, total content of unsaturated fatty acid was 59.7% including palmioleic, oleic, linoleic, $gamma $-linolenic, paullinic, eicosadienoic, dihomo-$gamma $-linolenic, erucic acids. Refined tra catfish oil is pale yellow, liquid state at ambient temperature without strange odor. Obviously, our treatments elevated quality of tra catfish oil to reach the Codex 2017 standard.
