Secondary Device

In the process of the operation and maintenance of secondary devices in smart substation, a wealth of defect texts containing the state information of the equipment is generated. Aiming to overcome the low efficiency and low accuracy problems of artificial power text classification and mining, combined with the characteristics of power equipment defect texts, a defect texts mining method for a secondary device in a smart substation is proposed, which integrates global vectors for word representation (GloVe) method and attention-based bidirectional long short-term memory (BiLSTM-Attention) method in one model. First, the characteristics of the defect texts are analyzed and preprocessed to improve the quality of the defect texts. Then, defect texts are segmented into words, and the words are mapped to the high-dimensional feature space based on the global vectors for word representation (GloVe) model to form distributed word vectors. Finally, a text classification model based on BiLSTM-Attention was proposed to classify the defect texts of a secondary device. Precision, Recall and F1-score are selected as evaluation indicators, and compared with traditional machine learning and deep learning models. The analysis of a case study shows that the BiLSTM-Attention model has better performance and can achieve the intelligent, accurate and efficient classification of secondary device defect texts. It can assist the operation and maintenance personnel to make scientific maintenance decisions on a secondary device and improve the level of intelligent management of equipment.

Secondary Device

The Nottingham Obstacle Director (NOD) is an ultrasonic handheld aid designed to help visually handicapped people detect obstacles as they travel. NOD emits pulses of high-frequency sound up to 7½ feet ahead of the user. The pocket-sized secondary device requires little training and is intended to be used with a primary aid (long cane, dog guide). This article describes the development of the NOD and the results of two evaluation studies that tested the efficacy of the device.

In this paper, we investigate implications of running a cooling system of two silicagel/water adsorption chillers powered by a district heating network. The devices are connected in series, i.e., the heating water output from the primary chiller is directed to the secondary one. In consequence, the secondary device must deal with an even lower driving temperature and with temperature fluctuations caused by the primary device. We have evaluated three factors that influence the operation of those coupled devices: synchronization of their operating cycles, selection of their cycle time allocations (CTAs), and changing the heating water mass flow rate. Numerical analyses indicate that the performance of the secondary chiller drops significantly if the coupled devices that use the same CTA run asynchronously. The decrease is largest if the shift between the operating cycles is x=0.375 and x=0.875. We found that it is possible to reduce the negative influence of the asynchronous operation by implementing different CTA in each chiller. The best performance is achieved if the primary chiller uses an adsorption time to desorption time ratio f=1.0 and the secondary chiller uses f = 0.6–0.7.

This chapter discusses time travel as the secondary device for exploring the idea of liberty in Terry Gilliam's 12 Monkeys. It analyzes the juxtaposition between free will and determinism, in which the film seems to be caught in something of a bind. It also explains time travel that is one-directional, in which the scientists only ever send people into the past, never into their own future to see if their plan will pan out. The chapter talks about how 12 Monkeys seems to suggest that it is possible to influence the future, which is an idea that is entirely reliant on the illusion of linear time. It examines the debate between compatibilists and incompatibilists that centres on a failure to distinguish between that which is known and that which is real.
