Over the years, face recognition has been the research topic that has attracted many researchers around the world. One of the most significant applications of face recognition is the access control system. The access control system allows authorized persons to enter or exit certain or restricted areas. As a result, it will increase the security situation without over-investment in staff security. The access information can be the identification, time, and location, etc. It can be used to carry out human resource management tasks such as attendance and inspection of employees in a more fair and transparent manner. Although face recognition has been widely used in access control systems because of its better accuracy and convenience without requiring too much user cooperation, the 2D-based face recognition systems also retain many limitations due to the variations in pose and illumination. By analyzing facial geometries, 3D facial recognition systems can theoretically overcome the disadvantages of prior 2D methods and improve robustness in different working conditions. In this paper, we propose the 3D facial recognition algorithm for use in an access control system. The proposed algorithm includes the preprocessing, feature extraction, and classification stages. The application of the proposed access control system is the automatic sliding door, the controller of the system, the web-based monitoring, control, and storage of data.

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.

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).
