CHATGPT FOR POINT CLOUD 3D OBJECT PROCESSING

Abstract. Large-scale pretrained language models have been a revolution in human-machine communication. Recently, such language models also generate code for required tasks. The objective of this work is to evaluate the functionality of the codes generated by ChatGPT (version 15-Dec-2022) for point cloud processing. The programming language selected for the test was MATLAB due to the extensive use in prototyping and toolboxes for Computer Vision and LiDAR. Using the Question-Answer system, the ChatGPT was asked for codes to calculate surface normals, curvature, eigenvalues, and eigenfeatures, with specific parameters and outputs. The provided codes were compiled and executed. The results show that ChatGPT can generate functional code for very specific and short applications, however, it is not capable of generating large code involving the correct use of loops, indexes, or equations.

The Resistance of Montessori Education to Social-Media Regimentation

Maria Montessori's educational proposal had a revolutionary significance since its origins. It freed childhood from the raising social marginalization to a "golden age". In a period marked by widespread national-popular illiteracy, a "New Education" originated exactly among the poorest social classes, represented a valuable tool for the literacy and regimentation of the masses to the rising fascist ideology. Montessori avoided it, paying with obstructionism and discredit. However, even today, Montessorian theory keeps on gaining credit as a "pedagogy of resistance" to the technical and technological revolution of information and communication. She is not even adverse to the use of technology in daily life or in education. Far from stopping the technical progress and the social technological literacy, it is a question of stemming the educational deprivation of the young people experience, rediscovering an active, direct and participative learning, with a specific attention to the early childhood. Experience offers a good and attractive alternative to the standstill caused by the overuse of the mass communication means. Preserving the 0-3 years children from the early abuse of technology, provides a "dilating education" of childhood's fields of experience and evolutive possibilities. In this way the child is ready to approach the technologies, in order to enjoy without suffering their growing capacities.

Starlink: A Revolution in Global Satellite Internet Communication

Abstract: The evolution of global communication infrastructures is entering a new phase with the introduction and development of Starlink, a satellite constellation project by SpaceX. Due to the [COVID-19], people all over the world need high-speed Internet connections, and India is one of the world's best copied consumer markets. Starlink has advised its customers around the world, including India, to allow all schools and organizations to access high-speed internet over the 'distance' of satellites and in the nature layer. Daily tasks are done online, and they urgently need high-speed Internet connection. There are demands, there are solutions directly from Sky, but Reliance JIO, Vodafone-Idea, Airtel etc. There are other service providers such as. Use FTTH, mobile networks Road and satellite internet, people are already using the internet, but the speed of the internet could be the turning point. Another point to consider is the price of $99 and $499, which may create some problems in the market because the Indian market is price sensitive. Starlink's architecture consists of low Earth orbit (LEO) satellites, which aim to minimize latency and maximize throughput, representing a significant departure from traditional geostationary satellites. In this research article, the author tries to find out what people think about Starlink's other business activities such as announcing products that start providing internet from SKY and competing with manufacturers in the market

The Spanish Gough maps: first pre-postal maps of the Iberian Peninsula in its European context

In this paper, we study two singular maps, the Modern Map of Spain, attributed to Cardinal Margarit, and Spagna con le distantie de li loci; made in northern Italy in the late 15th and early 16th centuries. Like the British Gough map, both already show communication networks with expressed distances. Using formal analysis, statistical methodology, and computer processing, we present the cartographic characteristics of each one and relate them to their historical context, updating the scarce information available until now. We explain their relationship as two milestones of the same cartographic process. At the same time, we study the routes represented, finding out the units of measurement used and the communication networks that both maps show us in the context of the Revolution of Communications that the Renaissance represented in Europe. The research has allowed us to attribute a new dating to them, question the traditional authorship, and advance a theory on the transport networks’ functionality, demonstrating that both maps are part of a cartographic and historical process at the European level. All these updates to the vision on the first maps of communications in Western Europe established new contributions to the relationship between maps and itineraries. It contributes to filling a void occupied in solitary, until now, by the map of Gough of Great Britain.

Holistic Trash Collection System Integrating Human Collaboration with Technology

Effective waste management is of paramount importance as it contributes significantly to environmental preservation, mitigates health hazards, and aids in the preservation of precious resources. Conversely, mishandling waste not only presents severe environmental risks but can also disrupt the balance of ecosystems and pose threats to biodiversity. The emission of carbon dioxide, methane, and greenhouse gases (GHGs) can constitute a significant factor in the progression of global warming and climate change, consequently giving rise to atmospheric pollution. This pollution, in turn, has the potential to exacerbate respiratory ailments, elevate the likelihood of cardiovascular disorders, and negatively impact overall public health. Hence, efficient management of trash is extremely crucial in any society. It requires integrating technology and innovative solutions, which can help eradicate this global issue. The internet of things (IoT) is a revolutionary communication paradigm with significant contributions to remote monitoring and control. IoT-based trash management aids remote garbage level monitoring but entails drawbacks like high installation and maintenance costs, increased electronic waste production (53 million metric tons in 2013), and substantial energy consumption for always-vigilant IoT devices. Our research endeavors to formulate a comprehensive model for an efficient and cost-effective waste collection system. It emphasizes the need for global commitment by policymakers, stakeholders, and civil society, working together to achieve a common goal. In order to mitigate the depletion of manpower, fuel resources, and time, our proposed method leverages quick response (QR) codes to enable the remote monitoring of waste bin capacity across diverse city locations. We propose to minimize the deployment of IoT devices, utilizing them only when absolutely necessary and thereby allocating their use exclusively to central garbage collection facilities. Our solution places the onus of monitoring garbage levels at the community level firmly on the shoulders of civilians, demonstrating that a critical aspect of any technology is its ability to interact and collaborate with humans. Within our framework, citizens will employ our proposed mobile application to scan QR codes affixed to waste bins, select the relevant garbage level, and transmit this data to the waste collection teams’ database. Subsequently, these teams will plan for optimized garbage collection procedures, considering parameters such as garbage volume and the most efficient collection routes aimed at minimizing both time and fuel consumption.

Information security in the space age: Britain’s Skynet satellite communications program and the evolution of modern command and control networks

ABSTRACT Britain initiated its Skynet satellite communications program in 1966 to provide assured connectivity with its forces across the world. Using recently declassified documents, this article reframes the history of British space activities by elucidating how the requirements for flexible and secure defense communications shaped U.K. space policy during the Cold War. Although Skynet inaugurated a communications revolution, it was the product of the longstanding British priority of possessing global information networks under sovereign control. In the Space Age, however, Britain had to reconcile its desire for an autonomous satellite communications network with the reality that American assistance was vital.

Impact of Mass Media and Globalization

“Curiosity” is an inherent and important quality of human nature. Based on which human spiritual and physical development becomes possible. The history of human race has been changing time and time again. It has undergone changes especially as a result of economic, social, and political revolutions. In all these revolutions, the contribution of two major revolutions has been important in changing the manner, style, and approach of human society. There are two such revolutions that have radically changed the pattern of human life, one is the industrial revolution and the other is the communication revolution. The breadth of these two revolutions or the extent of their influence may be different but these two revolutions have had a radical impact on human society. The resulting social and economic changes are different in each country. The present age is known as the age of knowledge and information. Mass media has affected the people of every society to such an extent that it is difficult to imagine how the society would be without it. Mass media such as newspapers, magazines, magazines, pamphlets, radio, books, films, television, smart phones and internet etc. have made a profound impact on human life today. Modern mass media have reached a wider audience than traditional media. People get so much information through mass media that as a result the present age is called the knowledge age. Information travels from one corner of the world to another in the blink of an eye. The era of globalization has complemented these two.

Why the Discovery of the Overlapped Multiplexing Principle is Bound to Cause a Revolution in Communication and Information Technology?

Abstract This article firstly introduces the overlapped multiplexing principle discovered by Prof. Daoben Li, and the new channel capacity derived from it, which is far beyond the capacity of Shannon's channel, and then introduces the characteristics and superiority of the waveform coding theory and the brand-new communication system, OVXDM, which is the cornerstone of his work. The article exposes two paradoxes and major errors of Shannon's information theory that violate the basic principles of physics, and makes predictions about the future development of communication and information technology. It criticizes several erroneous views on the development of 6G mobile communications: 6G should move to millimeter-wave terahertz band, the only means to improve the spectral efficiency of mobile communications is ultra-large-scale MIMO, and exposes that the U.S. Starlink and StarShield satellites can realize the global Internet 6G communications when the deception, the essence of which is the seizure of space resources and maintenance of the U.S. space hegemony. He emphasizes the great advantage of overlapped multiplexing waveform coding over Shannon coding, and points out that the Internet is only a network built under the guidance of the old Shannon multi-user network theory, which is as outdated as Shannon's information theory and should be eliminated. The Internet and GPS are the kingpin espionage tools of the United States to control the global information hegemony and steal information from other countries. In order to abandon the U.S. information hegemony, our country must leave the GPS in addition to the Internet! Under the guidance of the theory of subversive overlapped multiplexing multi-user network, the author puts forward suggestions on the establishment of our country's independent ultra-large-capacity wide-area Ov information network, which is a brand-new integrated network including space, sky, ground, ground to underwater, underwater and other categories, with a capacity much higher than that of the Internet.

Secure and Private Internet of Things for Industry, Training, and Homes: A Communications Solution for Connected Devices

We are currently living in the era of the Internet of Things (IoT) [1], which has been fostered by the electronic and communications revolution that happened in recent decades. The already great number of devices connected is continuously increasing, while their size and energy consumption keep decreasing. These IoT devices offer network interfaces that allow the interaction between a user/manager and the device through the network. These interfaces are usually developed by the manufacturers, and so, they constitute a private software interface (PSI). Within the IoT, a great variety of devices, such as, for example, appliances and other electric equipment, are publicly accessed. The essence of the IoT’s structure is presented in Figure 1, where appliances are accessible through a smartphone and their local area network (LAN). This basic architecture has been used in older IoT works such as [2]. To get this accessibility, the user must first register in a cloud, which is usually run by the manufacturer of the appliance, meaning that the management of the data is completely unknown for the end user in most cases. This lack of privacy does not dissuade people from using those devices (in many cases, because the only alternative is to not use such a device at all), but also, nowadays, people manage a large part of their professional, personal, and leisure information through the Internet [3], within a cloud (cloud computing) [4].

Gain Enhancement of Composite Photonic Crystal Microstrip Patch Antenna Inspired by Maxwell Garnett Model for C‐Band, X‐Band and Ku Band Applications

AbstractThe latest developments in communication systems require an economical, light‐weight, compact size, and excellent performance in microstrip patch antennas in order to meet the requirements of the upcoming implementation. The optical, electrical, and physical properties of different materials have an impact on the design of antennas. An innovative composite photonic crystal microstrip patch antenna with outstanding gain has been developed. For composites of fumed silica embedded in RT‐Duroid dielectric material, the effective permittivity is calculated using the Maxwell‐Garnett model. The performance of composite antennas for different volume fractions and various dielectric substrate thicknesses is studied. The resonance frequencies of composites also shift from the X‐band to the C‐band with an increase in volume concentration, which is suitable for wireless communication systems. This investigation provides a perspective on how composite substrates can represent a communication revolution by providing an alternative to substrates that are readily accessible commercially in situations when the material qualities are insufficient. The photonic crystal composite antenna records the highest gain of 13.89 dB with the coverage of C‐band, X‐band, and Ku‐band, whereas the composite antenna reaches the best gain of 10 dB with the coverage of C‐band and X‐band.

Lithium Sulfide –Carbon Composite Use as Positive Electrode in Post Lithium Ion Batteries Technology

Li‐ion batteries (LIBs) are the powerhouse for the electronic devices in this modern mobile society, and enabler of the current communication revolution. Consumers demands advanced electronics and sustainable industries in general. To satisfy these demands, the new generation of rechargeable batteries need to provide much higher energy and power density than the actual technology. Commercial LIBs consist of lithium cobalt oxide as positive electrodes and graphite as a negative electrode, this system has energy density values ca. 250 WhL-1.Lithium-sulfur is commonly considered as one of the most promising chemistries for improve traditional lithium-ion batteries in weight sensitive applications due to high theoretical capacity of lithium sulfide (Li2S) and high gravimetric energy density of such cells. Li2S provides a promising route for lithium storage due to high theoretical specific capacity (1166 mAh g−1). This positive electrode material can be coupled with lithium-free negative electrode to develop high-energy-density batteries; this can improve the safety of the devices. Li2S is significantly more thermally stable, and offer greater mechanical stability as no further volumetric expansion occurs upon cycling.Li2S particles must be handled only in inert atmospheres (making production of high-performance cathode materials, on a commercial scale, quite difficult) and suffer from rapid degradation in cells during cycling. There are still challenges with it (e.g., low conductivity, high over potential and irreversible polysulfide diffusion), which have prevented the S utilization and stability. The dissolved polysulfides deposit on the surface of both electrodes resulting in a rapid impedance growth, loss in active material and ultimately battery failure.The complex synthesis method of Li2S–carbon composites restrains the large-scale productivity. We propose an easy and time saving method to synthesize a Li2S based nanocomposite cathode material by wet milling.This work may shed fresh insight into bridging the huge gap between high energy and safety of rechargeable cells for feasible applications.

Study on the wireless sensor networks routing for Low-Power FPGA hardware in field applications

Very intelligent compact sensors with low-power and inexpensive solutions have been created because of the industrial revolution and subsequent advancements in electrical technology and wireless communications. Modern innovative enhancements have been made for the utilization of small, low-price, and low-power wireless communication devices with fast processing capabilities. The sensor node communication and routing play a significant role in the configuration of a specific WSN environment. There are three types of WSN routing: proactive, reactive, and hybrid. DSDV and OLSR are two proactive routing technologies. AODV and DSR are reactive routing technologies. DSDV Routing requires a progress update of its routing tables even when the network is not in use, which uses battery power and generates negligible data. As a result, this protocol is inappropriate for networks that are both huge in scope and very dynamic. OLSR maintains track of all potential solutions in a routing table. The overhead from control messages rises as there are more mobile hosts. It requires more processing power than other protocols while looking for alternate routes. The DSR protocol relies on the minimal hop count parameter to pick the way without considering other parameters that impact routing algorithm performance, such as energy consumption, residual energy, and connection stabilities. The FPGA realization provides an ascendable computing environment for WSN planning in a specific region. The research articles emphasize the hardware chip simulation and analysis of these routing protocols which can be further applied for field applications and configuration The network performance is evaluated using several performance metrics such as throughput, control overhead, delay, packet delivery ratio, and power consumption. This study offers a key method for creating FPGA-based power estimation and verification models for a WSN planning environment.

Capitalismo de plataforma e tipologia constitucional das plataformas digitais: entre mercados, praças públicas, anfiteatros e estradas

This text deals with a proposed classification of digital platforms, based on a constitutional typology and represented by the archetypes of the “Market”, the “Public Square”, the “Amphitheatre” and the “Roads”. The article begins by analyzing the heuristics for understanding the digital age (speed, complexity, ambivalence, and uncertainty). In sequence, the industrial and communication revolutions are covered, until the advent of the digital age. Furthermore, it is demonstrated that technological progress is not a simple deterministic march but is also subject to political and social choices. It continues with the exposition of the evolution of the concept of platform, its main characteristics (network effects, non-neutrality of prices, scalability at “almost zero” marginal cost, intensive use of data and algorithms, and tendency to concentration in quasi-natural monopolies). Moreover, the current concept of the multilateral digital platform is presented, as well as its main functions (coordination, governance, and dispute resolution). The article ends with an analysis of the main classifications already presented for digital platforms, as well as proposing the outline of a new classification, based on the aforementioned constitutional typology.

The role of social media in promoting cultural rights

The current communications revolution, and in particular social media, has opened a new era of human cultural development, making it possible for all peoples of the world to get to know each other, especially in the field of culture and cultural exchange, transfer of values and principles, science, knowledge, literature and arts that this cultural diversity and exchange of cultures will continue to exist between peoples thanks to modern technological means, as social media contribute greatly to the promotion of cultural rights through openness, interaction and cultural communication between different peoples of the world with different cultures. provides advanced means of communication, Today, it is witnessing great communication between different cultures after the various social media ensured for them the possibility of spreading and reaching different distances and places far from the place in which they were found or grown, as they provided the elements of culture with the possibility of moving from human societies to another and from one generation to another as it secured It has the necessary mechanisms for crossfertilization, mixing and interaction with other cultures prevailing in other peoples.

Self-Proficiency of Essential Technology Skills of Undergraduate Students at a Coastal University in Ghana

One of the numerous challenges facing education today is that of preparing students and staff for globalization and the information and communication revolution. Policymakers, educationists, non-governmental organizations, academics, and ordinary citizens are increasingly concerned with the necessity to make their societies competitive in the evolving information economy. Globalization and advancements in technology have led to an increased utilization of ICTs in all sectors, and education is no exception. Uses of ICTs in education are widespread and are repeatedly growing worldwide. Thus, this study investigated undergraduate students’ self-proficiency of essential technology skills in the University of Cape Coast, Ghana on the use of technology for various educational purposes. The study adopted the descriptive survey design using 318 randomly selected respondents from three different programmes in the university. The quantitative data collected were analyzed using descriptive statistics. The study found that students possessed technical abilities needed to perform some specific tasks such as changing the default settings of tech tools to meet specific needs and also make configurations to connect computers to a network. However, respondents were unable to perform advanced formatting functions such as customized tabs, insert page breaks, query databases and sort the results, and using styles as well as unable to create and manage classroom webpages.

STATE, NEOLIBERALISM AND FINANCIALIZATION

As liberalism took roots during the 18-th and 19-th centuries, and as United States closed to such an overwhelming position which has made it a political actor with outmost importance at global level especially after the 1-st World War, there was another activity which accompanied this evolution, which is connected to financial activities and their speculative character; one important effect of these actions was the Great Depression in 1929-1939, which threw waves of shocks in America, and all over the world with unforeseen consequences. After the experiences brought upon by the Second World War, doubled by fresh memories of Great Depression, Keynesianism and its system torsed around Bretton Woods negotiations imagined a greater role for the state in relation with the market, especially the international financial market. As this gave birth to what can be seen as the Golden Age of capitalism, it is important to mark the role of state versus market during this period. But as the British Empire was closing to its end, London found a way to reinvent itself, as heir of the dying empire. In order to hold a central position in world affairs, it has looked at money, and the power they could provide: to save its system, London help inventing Eurodollar, circumventing the key-aspects of Bretton Woods and what it stood for. Slowly but surely, the market – especially the financial market – has gained more central position in face of state, and with it, the financialization of the economy. Between 1956 and 1980 there were identifiable clashes in state-market nexus, the most important being triggered by the oil shock in the 70’s; but as world entered the 80’s, it became clear that the market would gain the upper hand. The Reagen-Teacher understanding was the visible point of the picture regarding the shift of importance from state to market. The 90’s will only bring new and fresh markets ready to embrace globalization, sustained by the revolution in communications, which was already in full development. And now we see a minimal state put in a marginal position by the forces of economic globalization and the philosophy of free-market, while the market is seen as a “know and fix everything”; its invisible hand can overcome any temporary disequilibrium. A recurrent question needs to be addressed: where is the state, with its main attributes, in order to protect the people from selfish market forces?

(Re)imagining Ndau indigenous religion of Zimbabwe in the digital age

ABSTRACT The twenty-first century has been characterized by various digital communication technologies that are a major agent of globalization. Today Africans find themselves in new geo-cultural contexts within their countries and in the diaspora through migration triggered by many factors. These geographical dislocations disrupt the traditional clan settlement patterns and in turn challenge indigenous media of communication in indigenous African societies. Digitalization becomes a lifestyle in this globalizing world. African Indigenous Religions (AIRs) practitioners are embracing digital communication facilities. However, there are fears within some sections of African indigenous communities whether African Indigenous Religions could utilize the emergent communication technologies and remain unscathed. These sections hold the view that digital communication technologies are incompatible with the African indigenous worldview. There has been scanty literature on AIRs in general and Ndau religio-culture in particular to respond to these fears. Mindful of the variations that characterize AIRs, this article uses Ndau religio-culture of Zimbabwe to contend that AIRs are dynamic and have long been digital. In this regard, digitalization is neither new nor opposed to African indigenous religions. Rather, it is the amplification of the old as it fuses with the new. This empirical article employs the theological ethnography design to access the meaning embedded in the indigenous Ndau’s interaction with the digital communication services. Afro-centricity provides the lens to glean phenomena from the standpoint of the Ndau as key players in their life-worlds. The research findings were that the Ndau have a penchant for innovation and creativity in ways of thinking and doing things in order to survive in new circumstances. The article concludes that the Ndau religio-culture is an enduring heritage that has responded to the digital communication revolution by finding ways of reimagining and revitalizing its communication repertoire to be compliant with the dictates of the digital era.

Experimental Research in Synthetic Molecular Communications – Part I

Since its emergence from the communication engineering community around one and a half decades ago, the field of Synthetic Molecular Communication (SMC) has experienced continued growth, both in the number of technical contributions from a vibrant community and in terms of research funding. Throughout this process, the vision of SMC as a novel, revolutionary communication paradigm has constantly evolved, driven by feedback from theoretical and experimental studies, respectively. It is believed that especially the latter ones will be crucial for the transition of SMC towards a higher technology readiness level in the near future. In this spirit, we present here a comprehensive survey of experimental research in SMC. In particular, this survey focuses on highlighting the major drivers behind different lines of experimental research in terms of the respective envisioned applications. This approach allows us to categorize existing works and identify current research gaps that still hinder the development of practical SMC-based applications. Our survey consists of two parts; this paper and a companion paper. While the companion paper focuses on SMC with relatively long communication ranges, this paper covers SMC over short distances of typically not more than a few millimeters.

States, Modes, Fields, and Photons in Quantum Optics

The quantum nature of light enables potentially revolutionary communication technologies. A key to advancing this area of research is a clear understanding of the concepts of states, modes, fields, and photons. The concept of field modes carries over from classical optics, while the concept of state has to be considered carefully when treating light quantum mechanically. The term "photon" is an overloaded identifier in the sense that it is often used to refer to either a quantum particle or the state of a field. This overloading, often used without placing it in context, has the potential to obfuscate the physical processes that describe the reality we measure. We review the uses and relationships between these concepts using modern quantum optics theory, including the concept of a photon wave function, the modern history of which was moved forward in a groundbreaking paper in this journal by Iwo Białynicki-Birula, to whom this article is dedicated.
