A Smooth Path between the Classical Realm and the Quantum Realm

A simple example of classical physics may be defined as classical variables, p and q, and quantum physics may be defined as quantum operators, P and Q. The classical world of p&q, as it is currently understood, is truly disconnected from the quantum world, as it is currently understood. The process of quantization, for which there are several procedures, aims to promote a classical issue into a related quantum issue. In order to retain their physical connection, it becomes critical as to how to promote specific classical variables to associated specific quantum variables. This paper, which also serves as a review paper, leads the reader toward specific, but natural, procedures that promise to ensure that the classical and quantum choices are guaranteed a proper physical connection. Moreover, parallel procedures for fields, and even gravity, that connect classical and quantum physical regimes, will be introduced.

Magnetogenesis and the Cosmic Web: A Joint Challenge for Radio Observations and Numerical Simulations

The detection of the radio signal from filaments in the cosmic web is crucial to distinguish possible magnetogenesis scenarios. We review the status of the different attempts to detect the cosmic web at radio wavelengths. This is put into the context of the advanced simulations of cosmic magnetism carried out in the last few years by our MAGCOW project. While first attempts of imaging the cosmic web with the MWA and LOFAR have been encouraging and could discard some magnetogenesis models, the complexity behind such observations makes a definitive answer still uncertain. A combination of total intensity and polarimetric data at low radio frequencies that the SKA and LOFAR2.0 will achieve is key to removing the existing uncertainties related to the contribution of many possible sources of signal along deep lines of sight. This will make it possible to isolate the contribution from filaments, and expose its deep physical connection with the origin of extragalactic magnetism.

This system of ours is a daisy-chained series of electronics having a DIN-rail compatible form factor, where each of the modules support all of the functionalities related to inter-module communication, autonomous computing and supporting physical connection and drivers to external interfaces.

Sentiment Analysis of Nepali COVID19 Tweets Using NB, SVM AND LSTM

The government's months-long total lockdown in response to the COVID19 outbreak has resulted in a lack of physical connection with others. This resulted in a massive increase in social media communication. Twitter has become one of the most popular places for people to communicate their thoughts and opinions. As a result, massive amounts of data are created every day. These data can assist businesses in making better judgments. In the case of Nepal, there has been relatively little investigation into the text's analysis. Because few researchers are working in the field, development is slow. In this study, Four language-based models for sentiment analysis of Nepali covid19 tweets are designed and evaluated. Because the number of individuals using social media is expected to skyrocket in the next few days, companies will benefit from an AI-based sentiment analysis system. It will greatly assist firms in adapting to the changing climate.

Feeder Topology Configuration and Application Based on IEC 61850

Distribution automation (DA) and Internet of Things (IoT) all need the topology information of power distribution network to support some applications, such as fault diagnosis, network reconfiguration and optimization. IEC 61850 is a general communication model and standard for information exchange between intelligent electronic devices (IEDs). However, it has no mechanism for feeder topology information exchange. This paper solves this problem by developing the corresponding information model. Firstly, a feeder model is established as a container of the equipment along a distribution line. Secondly, logical models, such as terminal and connection nodes, are added to describe the physical connection relationship between the electrical equipment. Taking a circuit breaker as an example, this paper introduces how to add the terminal attribute to an existing logical node (XCBR). The physical connection between the circuit breaker and other electrical equipment is described by adding the logic node LCNN. Then, a new logical node LTPN is added to describe the logical connection between the devices. A new logical node, FTPA, is added to describe the status of the topology analysis and the topology results. Based on these new logical nodes, this paper proposes the mechanism of topology information exchange between IEDs. Three IEDs and the IEEE 13-node model are used to build an experimental environment. The result verifies the effectiveness of this method. More distributed applications can be used to test the validity and interoperability of the proposed model.

Closeness is Not Accessibility: Isolation and Depopulated Rural Areas in the Proximity of Metropolitan Urban Areas, A Case-Study in Inland Spain

The increase of accessibility is one of the most important strategies to achieve territorial cohesion and slow down depopulation processes in rural areas. Accessibility is a wide concept with a range of interpretations. When it comes to rural areas, usual accessibility measures introducing proximity and ease of physical connection could lead to misinterpretations and a lack of knowledge for rural areas. This study proposes an accessibility analysis based on connection and function of one of the most depopulated territories in inland Spain: the province of Guadalajara (NUTS-3) which constitutes an interesting case-study because its proximity to the Spanish capital city (Madrid) and the integration of part of the province on its dynamics and economic processes. Results show different rural accessibility levels useful for public policies and decision making on infrastructures. In addition, the accessibility model suggested can be applied in other depopulated rural areas of Europe.

Technical Analysis of ZigBee Wireless Communication

Information transformed over a long distance without any means like wires, cables and other forms of conductors. The term wireless communication is broad which incorporate different forms of communication and connecting between more devices without any mode of wires through this wireless communication technology. In pre-industrial age, the first network of wireless was developed. This technology has more advanced and featured with upcoming technology and this is one form is future generation. This technology has more impact in growing world. The name wireless communication itself gives the meaning without any physical connection the communication is done in better way. Wireless communication has exponential growth in cellular system and over around two to three billion users.

In this paper we propose an application written in LabVIEW through which a number of transducers or sensors are controlled so that the data from them are taken according to a certain algorithm and also this application realize the data processing. Control consists in selection for each of these transducers, their inputs selection and retrieves information from them. The physical connection between used transducers and master is made through RS-485 bus and the transmission protocol used is Modbus RTU.
