Transfer Protocol

Abstract Tag ownership transfer is an important process for RFID system. Besides the user needs to obtain the information concerning the quality of products in some scenarios, which are attached by tags. In this paper, we proposed an ownership transfer protocol with retrospective ability and analyzed its security level by using GNY logic. The results indicate that the ownership transfer protocol provides high-quality security to RFID systems. It provides an authentication between the tag and owners and location privacy of the tag. The protocol enables to resist a replay attack, man-in-the-middle attack and desynchronization attack. It also protects forward security and backward security. Moreover, it provides the information concerning the quality of the product attached by tags. We analyzed the performance of the protocol and implemented it. The results of the empirical study show that the cost time of a tag is less than some other protocols and suitable for low-cost tags.

Conventional methods for assessing the quality of components mass produced using injection molding are expensive and time-consuming or involve imprecise statistical process control parameters. A suitable alternative would be to employ machine learning to classify the quality of parts by using quality indices and quality grading. In this study, we used a multilayer perceptron (MLP) neural network along with a few quality indices to accurately predict the quality of “qualified” and “unqualified” geometric shapes of a finished product. These quality indices, which exhibited a strong correlation with part quality, were extracted from pressure curves and input into the MLP model for learning and prediction. By filtering outliers from the input data and converting the measured quality into quality grades used as output data, we increased the prediction accuracy of the MLP model and classified the quality of finished parts into various quality levels. The MLP model may misjudge datapoints in the “to-be-confirmed” area, which is located between the “qualified” and “unqualified” areas. We classified the “to-be-confirmed” area, and only the quality of products in this area were evaluated further, which reduced the cost of quality control considerably. An integrated circuit tray was manufactured to experimentally demonstrate the feasibility of the proposed method.

One of the popular uses of UAVs in photogrammetry is providing an archaeological documentation. A wide offer of low-cost (consumer) grade UAVs, as well as the popularity of user-friendly photogrammetric software allowing obtaining satisfying results, contribute to facilitating the process of preparing documentation for small archaeological sites. However, using solutions of this kind is much more problematic for larger areas. The limited possibilities of autonomous flight makes it significantly harder to obtain data for areas too large to be covered during a single mission. Moreover, sometimes the platforms used are not equipped with telemetry systems, which makes navigating and guaranteeing a similar quality of data during separate flights difficult. The simplest solution is using a better UAV, however the cost of devices of such type often exceeds the financial capabilities of archaeological expeditions. <br><br> The aim of this article is to present methodology allowing obtaining data for medium scale areas using only a basic UAV. The proposed methodology assumes using a simple multirotor, not equipped with any flight planning system or telemetry. Navigating of the platform is based solely on live-view images sent from the camera attached to the UAV. The presented survey was carried out using a simple GoPro camera which, from the perspective of photogrammetric use, was not the optimal configuration due to the fish eye geometry of the camera. Another limitation is the actual operational range of UAVs which in the case of cheaper systems, rarely exceeds 1 kilometre and is in fact often much smaller. Therefore the surveyed area must be divided into sub-blocks which correspond to the range of the drone. It is inconvenient since the blocks must overlap, so that they will later be merged during their processing. This increases the length of required flights as well as the computing power necessary to process a greater number of images. <br><br> These issues make prospection highly inconvenient, but not impossible. Our paper presents our experiences through two case studies: surveys conducted in Nepal under the aegis of UNESCO, and works carried out as a part of a Polish archaeological expedition in Cyprus, which both prove that the proposed methodology allows obtaining satisfying results. The article is an important voice in the ongoing debate between commercial and academic archaeologists who discuss the balance between the required standards of conducting archaeological works and economic capabilities of archaeological missions.

One of the most important problems is the timely and accurate accounting of costs and output. Providing benefits from sales, obtaining benefits from enterprises and, accordingly, improving the quality of products. In this regard, the problem of building a system of state accounting of costs in agriculture is very relevant for national scientists. The article explores the methods of calculating the cost of livestock production by the traditional method and the ABC method, and also studies the prospects for determining the nature of ABC in the practice of enterprises. The study should lead to difficulties. This system is not widespread and does not have developed guidelines. This can lead to an incorrect distribution of processes and costs, a distortion of the calculation of the cost of production. Nevertheless, with a competent approach to using these parameters, you can get more accurate results.

Production of high precision circular scales is a complicated process requiring expensive equipment and complex processes to achieve. Precision angle measurement equipment tends to be very expensive and therefore not accessible to all in need. Simplification of production of such devices can lead to reducing costs of angle measurement systems ensuring easier accessibility. A new method of producing precision circular scales using low cost mass production can reduce the costs of these devices drastically. Therefore, utilising a common CD technology as the basis for such scales is analysed. This paper deals with the analysis of the newest laser cutting method for plastic circular scales. Preliminary results of manufacturing such scales are presented in the paper as well as measurements of the grating of the scale were performed. The quality of different scales manufactured using different laser types is analysed in the study. The cost – effective alternative of manufacturing circular scales is discussed in the paper.
