    Abstract: Calculations of adsorption and reaction mechanism on ZnO  surface have been investigated. In this work, the deposition of six atomic copper clusters (6Cu) on ZnO  surface (called 6Cu/ZnO  model), using density functional theory was employed to calculate for CO and H2O co-adsorption. In performance, on ZnO  surface, 6Cu were adsorbed to obtain four stable sites of 6Cu/ZnO model, called as 6Cu-I, 6Cu-II, 6Cu-III, and 6Cu-IV. The calculated results found that the 6Cu-IV was the most stable surface model, thus, used to examine the co-adsorption of CO and H2O molecules. Further, CO and H2O co-adsorption on ZnO  surface were calculated also to compare with 6Cu/ZnO surface. Based on co-adsorption energy calculations indicated that CO and H2O co-adsorption on 6Cu/ZnO surface were more favorable than on ZnO  surface. The studied results will provide an insight into the effective adsorption of cluster on ZnO-based surface by deposition.

    Abstract: Nowadays, the applications of automatic control systems have been developing very fast in many diversify of the industry fields. One of the most significant industry that is needed to care and focus to develop this automation technology in order to reduce the huge number of workers and increase the productivity is the seafood industries. Normally, the seafood industry has a lot of workers to carry out everything manually. There still remain many research topics relating to this field to help this industry to develop in the trend of 4.0 ages. The semi–automation shrimps Tempura frying production line is a system to make Tempura shrimps with high productivity. The workers simply put the shrimps into the serial of chain frying molds and the system will automatically do the whole production process to produce the completed Tempura shrimps. The whole process to produce Tempura shrimps includes the following steps: (1) Shaping shrimp and cover with powder solution by automatic powder solution spraying system; (2) Complete frying to make the shrimps to be cooked; (3) Oil draining system to remove the remain oil inside the shrimp and the powder cover. Then the finished products will be put into the frozen system to preserve. The whole production line will be separated into 3 main modules: Module 1: The shaping module (first time frying) and powder solution spraying module; Module 2: The deep fry module (second time frying); Module 3: The oil draining module. This paper introduces about the control system for each module and the controller of the whole system to make a complete semi-automation shrimp tempura frying production line. Some controller technology as On/Off, PID control algorithms are proposed to apply for the whole production line as: speed control of the stainless-steel chain conveyors, temperature control of the cooked tanks, quantitative control of the powder solution amount to be sprayed on the shrimps, the oil draining conveyor speed, the heat and air flow control of the oil draining module.

    Abstract: Currently, Tempura shrimp consumption is very high in most Japanese restaurants all over the world. There are many companies that produce Tempura shrimp to provide for many restaurants as well as to sell in many supermarkets in many countries. In fact, the benefits of this product are enormous for the seafood industry in Vietnam as well as in other countries. However, most of the companies that produce the Tempura shrimps manually by workers. There are a lot of workers who fry shrimp manually to keep the company productive. The quality of this product also bases on the skill of the workers. And, to satisfy the condition of mass production, the enterprise also needs the very large area to set up the workplace for the workers. Secondly, this situation leads to the practical results that the quality of Tempura shrimp is not identical, unstable and the amount of waste is very high. Therefor, the requirement for the application of automatic control system in this tempura field can help the company to solve these difficult problems. This issue is the primary focus of this document. It is the situation of the Tempura fried shrimp companies which lead them to implement automated systems to replace unskilled workers. This paper presents the design of the whole semi automation single-side Tempura shrimp frying production line to propose some innovation about the shrimp tempura frying process. The entire Tempura semi automation production line consists of 3 main modules. Each module can operate as an independent machine. The workers just put the coated shrimp in the molds and then the frying process will perform the remaining steps automatically. The first module (Module 1) is the shaping module or the first time frying module. The powder solution also installed with this module. The second module (Module 2) is the finished frying module. Finally, the oil drainning module (Module 3) using the technique of the hot heating airflow system to drain the excess oil inside the Tempura shrimps.

    Abstract: In considering the problem of saving spaces during the transportation of items from one station to another, for example, in warehouses, factories, hospitals, etc., an automatic transportation system (ATS) that could take advantage of the above ceiling spaces for the transportation of products is considered. Such a system guarantees that the activities occurring in the floor area will be maintained as usual. To achieve this requirement, the ceiling spaces of a building are used to construct an automatic multi-station multi-container (MSMC) transportation system. This system can transport items from one place to another in the whole system. This system is designed to utilize the spaces above the ceiling, and it has the advantage of saving floor space for transportation operations. This will increase the operational capability of the industries and also improve the productivity of the industry in which this system is implemented. The entire transportation system includes (1) the essential conveying system (which is a functional conveyor module with a specified number of containers); (2) the control block that can monitor and operate the system; and (3) the sensor block for detecting and identifying the containers. The content of this article focuses on the introduction of the mechanical system (1); the control system (2); and the operating principle of the whole system (3).

    Abstract: In this study, depositing with two copper atoms (2Cu) on ZnOsurface, obtaining 2Cu/ZnO surface model, and its applications then for adsorbed CH3OH were investigated using the density functional theory (DFT). In performances, 2Cu was adsorbed on ZnOsurface to form the model of 2Cu deposited over ZnO (2Cu/ZnO). Further, on 2Cu/ZnO surface model, the resulted analysis as density of state (DOS) and electron density difference (EDD) contour plot pointed out that two atomic Cu were formed by the transferred electrons from Cu to ZnO, leading Cu oxidation to become Cu+ ion, while was modeled 2Cu/ZnOsurface. To investigate CH3OH adsorption, many configurations of adsorbed CH3OH on the surface found, in which the most stable configurations were also identified. This result presented that methanol adsorption on 2Cu/ZnO is more favorable than that on ZnO in our previous works.

    Abstract: Introduction: A common problem in image restoration is image denoising. Among many noise models, the mixed Poisson-Gaussian model has recently aroused considerable interest. Purpose: Development of a model for denoising images corrupted by mixed Poisson-Gaussian noise, along with an algorithm for solving the resulting minimization problem. Results: We proposed a new total variation model for restoring an image with mixed Poisson-Gaussian noise, based on second-order total generalized variation. In order to solve this problem, an efficient alternating minimization algorithm is used. To illustrate its comparison with related methods, experimental results are presented, demonstrating the high efficiency of the proposed approach. Practical relevance: The proposed model allows you to remove mixed Poisson-Gaussian noise in digital images, preserving the edges. The presented numerical results demonstrate the competitive features of the proposed model.
