“The World Had Forgotten about Us”: Heterotopian Resistance in Richard Flanagan’s Wanting and Lloyd Jones’s Mister Pip

This article explores how the different forms of heterotopias present in Richard Flanagan’s Wanting (2008) and Lloyd Jones’s Mister Pip (2006) articulate problematic identity politics and cultural memory. In Wanting, the collocation of Mathinna’s story with that of the lost Franklin expedition offers a form of reclaiming. This article argues that Flanagan’s novel moves from heterotopias of deviation to a crisis heterotopia, displacing and debunking the compensation function of the colonial heterotopia to highlight the crushing of Aboriginal identity. This shifting heterotopia is doubled by Mathinna’s heterotopic carceral body, that is, body as confined space, which qualifies the act of reclaiming. In Mister Pip, heterotopias concern cultural memory as the island of Bougainville, secluded from the rest of the world, turns into the repository of the villagers’ culture juxtaposed with the reading of Charles Dickens’s Great Expectations (1860–1861). This article argues that Jones’s creation of a palimpsestic heterotopia allows him to resist Eurocentric views as well as to actualize postcolonial concepts. Jones’s novel calls for a dynamic appropriation of literature. Matilda’s ‘Pacific version’ of Pip’s story reflects the cracks in the Victorian and contemporary exploitations of the island. Readers’ immersions in these heterotopias do not provide an escape from but a thoughtful commitment to the past.

Study on Cross-Basin Ecological Compensation Mechanism and Compensation Standard

Water resources in China’s river basins are scarce, and the pollution that shrouds them is serious. Constant disputes have emerged between the upstream and downstream sectors due to the contamination of river basins. Moreover, China’s research on ecological compensation mechanisms and compensation standards is still immature at present. Thus, this study establishes a compensation model and introduces the compensation coefficient K, including the compensation coefficient K1 between the upstream and downstream governments and the compensation coefficient K2 between the upstream government and the central government. This paper adopts the Bargain Game Model and obtains the value of K2 through the decision-making process between the central government and the upstream local government. In addition, amendment to the final offer arbitration law is used to acquire the value of K1 by proving the existence and uniqueness of equilibrium. Then, this paper takes the Taohe River Basin as an example and combines the compensation model to analyze, using the simplified compensation function to determine the amount of emission pollution from upstream to downstream and the compensation that upstream should receive.

A Medium-Frequency Fiber Bragg Grating Accelerometer Based on Flexible Hinges

Mediumfrequency fiber Bragg grating (FBG) acceleration sensors are used in important applications in mechanical, aerospace and weapon equipment, and have strict requirements in terms of resonance frequency and sensitivity. A novel medium-frequency accelerometer, based on fiber Bragg grating and flexible hinges, is proposed in this paper. The differential structure doubles the sensitivity of the sensor while avoiding temperature effects. The structure model and principle for the sensor are introduced, the sensor’s sensing characteristics are theoretically analyzed, and the structure parameters for the sensor are determined through numerical analysis. The sensing experiments show that the resonance frequency of the sensor is approximately 2800 Hz, the sensitivity is 21.8 pm/g in the flat frequency range of 50–1000 Hz, and the proposed sensor has a good temperature self-compensation function and lateral anti-interference capability.

Design Concept and Structural Configuration of Magnetic Levitation Stage with Z-Assist System

Magnetic levitation technology is expected to provide a solution for achieving nanometer-scale positioning accuracy. However, magnetic leakage limits the application of the magnetic levitation stage. To reduce magnetic density, motors should be installed at an appropriate distance from the table. This increases the axis interference between the horizontal thrust and the pitching, making it difficult to achieve stable levitation. In this study, a magnetic levitation stage system that has a unique motor structure fusing a gravity compensation function and pitching moment compensation is proposed. This compensation mechanism operates automatically using the passive magnetic circuit structure, ensuring that noises from the coil current and the timing gaps do not affect the driving characteristics and that neither wiring nor sensors are required. The basic characteristics were evaluated through the driving experiments, and the efficiency of the proposed gravity and pitching moment compensation system was demonstrated.

SECURITY (GUARANTEE) PAYMENT AS AN INNOMINATED ENFORCEMENT OF OBLIGATIONS

The article is devoted to clarifying the features of a security (guarantee) payment as an innominated method of securing the enforcement of an obligation. As a result of the study, there are provisions that can serve as a basis for constructing a sub-institution of a security (guarantee) payment in the obligation law of Ukraine. The conclusion is justified that a security (guarantee) payment is possible only when the material objects of the main and accounting obligations are homogeneous. Homogeneity in security payments is that the subject matter and mode of performance of the principal obligation can be replaced by the same performance, but at the expense of reserved funds. A monetary security payment cannot provide non-monetary obligations in an obligation, since their fulfillment cannot be replaced by a monetary provision. It is proved that the security (guarantee) payment must have separate characteristics of the deposit, pledge, and predetermined losses. A distinctive feature of a security (guarantee) payment, in comparison with other methods of securing the performance of the obligation, is the weakened emphasis, which manifests itself at the stage of the occurrence of the obligation, allows to ensure obligations arising in the future. The regulatory fixation of a security payment in the Civil Code of Ukraine, of course, will be a logical result of its application in practice as an innominated method of ensuring the fulfillment of an obligation. The conclusion is justified that a security (guarantee) payment can perform a punitive function only indirectly: through the application of civil liability measures. In other words, a security payment is only a financial source of satisfaction for claims for forfeiture or damages, but unlike the mentioned measures of liability, a security payment does not have a punitive mechanism in its structure. A security payment is characterized by the existence of a compensation function that aims to restore the property sphere of the creditor, and not acting as a means of punishing the debtor. Attention is drawn to the need to introduce a certain mechanism for allocating funds from the estate of the person to whom they are transferred as a security payment. This mechanism will balance the interests of participants in civil traffic, leveling the risk of their non-return for the person who transferred money as a security payment.

Calibration Algorithm for Error Screening Based on Line Structured Light

The 3D measurement system based on line-structured light uses a camera to capture laser stripes due to changing in the shape of an object, and uses the acquired pixel coordinates for 3D reconstruction. System calibration is an important step in 3D measurement. The current camera calibration algorithm research mainly focuses on improving the algorithm itself, and there is less research on the influence of external factors. This paper proposes a coplanar hybrid calibration algorithm based on the error screening model by combining the error screening model, mathematical model and neural network model. It is mainly divided into two steps. The first step is to use the radial array constraint calibration algorithm based on the error screening model to solve the camera’s internal and external parameters. The second step uses the camera internal and external parameters obtained in the first step to convert the pixel coordinates into real three-dimensional coordinates, and compares the calculated three-dimensional coordinates with the actual coordinates. Using machine learning to establish a compensation network, get a compensation function, and use the resulting 3D world coordinates to perform point cloud stitching. Experiments show that compared with the traditional calibration algorithm, the calibration algorithm has a small error and reduces the calibration error by about 6.5%.
