关键词： Magnetic anomalies: modelling and interpretation   Fourier analysis   Fractals and multifractals  

摘要： Australia and North America arc the only two continent-wide regions, currently, with the complete wavelength spectrum of magnetic anomalies that can address the much-debated issue of the existence and understanding the magnetic state of the upper mantle. The depth to the base of magnetic sources (DBMS) has been extensively investigated in Australia in previous studies, yielding differing DBMS estimates across the continent. In this contribution, we re-assess the DBMS in Australia from aeromagnetic data using the defractal method, which simultaneously estimates the DBMS and the fractal parameter of the magnetic field. We test the effect of window size on DBMS estimates for the defractal method and conclude that a window size 10 times the expected DBMS is required for the defractal method. We also demonstrate the dependence of derived spectral slopes (and thereby depths) on the size of window by comparing spectral slopes obtained from window sizes up to 1000 km. Our analysis yields DBMS estimates between 25 and 60 km over Australia and are complexly related to temperature structure, magnetic mineralogy and petrology and geological history. Deeper DBMS estimates (-55-60 km) arc obtained for the Yilgarn Craton (West Australian Craton) and the Gawler Craton (South Australian Craton). These estimates are significantly deeper than the Moho, suggesting the uppermost mantle is ferromagnetic for these cold and old cratonic regions. Shallower DBMSs of 25 35 km are obtained in the Pilbara Craton, the eastern and southern part of the Delamerian Orogen, the northwestern part of the Canning Basin, Officer, Cooper and Georgina Basins and the Tasmanides. The areas of shallower DBMS are positively correlated with high heat flow in the regions. On the other hand, regions of large concentrations of radiogenic elements associated with the major metallogenic deposits have high heat flow arising from the radiogenic heat, but deeper DBMSs, for example the eastern margin of the Gawler Crato

摘要： The development of different Data Base Management System (DBMSs) and computer networks and the proliferation of communication led to an increase in the distribution of DBMS network displays. Major diversity issues and challenges include Different types of information, different types of rules and semantics, different DBMSs (recycling, etc.). Address here is a long-term goal of a diversified Database Management System (DBMS), no node. The network, where the user can give an integrated and customized view or mode, cannot support the data. It resides in a single database or database, managed separately by the same DBMS type (according to a single user claims) or by different DDBMSs. The main way to go about data sharing and access: downloading / loading and downloading to the computer from existing top business files and databases created as a result and long-distance desire in the existing DBMS, common interface. Covers are also an item of commercial availability that can become a problem with motivational installation, opportunity cost, and the need to share data with a diverse world. These platforms are partly part of the long-term goals that major research and development projects seek to develop. The calculations were first done on desktop-based systems, and therefore data-based. However, embedded time-dependent systems are required to measure the output events or output events of a given period, run at regular intervals, and more widely. Embedded course Advanced course basket is an effective teaching time-related program. Programming early learning habits are difficult to break in the current situation. Introducing time-related programs for beginners or sophomores, involving a balance between abstraction and resource awareness can provide a good foundation. Combined with a clean microcontroller and a timer, the synchronous state machine calculation model can provide such a balance. © 2021

摘要： Databank Systems was set up in 1967 by a consortium of New Zealand banks to share computing services. This was the first instance of computers being used to integrate the ledger accounts of all trading banks within a country, an innovation facilitated by the relatively small size of the country, the rising use of cheque facilities, and the realization that a joint effort would provide a more efficient service by enabling the pooling of resources to achieve scale from expensive computing technology. In 1972, Databank introduced time slicing, allowing nonbank customers to use spare capacity on the Databank system. This use of Databank outside the banking systems was controversial and the management of Databank was increasingly at odds with the Bankers Association. This article uses the example of Databank to address the tensions between consortium computing and the sale of spare time resources in banking.

摘要： Database systems research has been part of the academic culture in the Arab world since the 1970s. High-quality computer science and database education has been available at several universities within the Arab region, such as Alexandria University in Egypt. Many students who completed these programs have been drawn to database systems research and became globally prominent, such as Ramez Elmasri (professor at University of Texas, Amr El Abbadi (professor at University of California, Santa Barbara), and Walid Aref, professor at Purdue University. Today, many prominent database researchers are settling within the region and furthering its database research culture.
