Introduction

Computer technology has become an indispensable presence in modern society. In the 21st century, it has made progress in various fields. Amongst this progress, we must pay attention to the latest technology developments such as artificial intelligence (AI), blockchain, quantum computers, cloud computing, 5G networks, Internet of Things (IoT), femtosecond lasers, and nanotechnology. These technologies have the potential to significantly change our lives. However, reliable sources of information are necessary. In this blog, we will explain these technologies based on the latest research papers. We will deliver colourful explanations as a presence like that of a professor of mechanical engineering.

AI (Artificial Intelligence)

Artificial Intelligence (AI) is one of the rapidly advancing technologies in recent years. By using techniques such as machine learning and deep learning, computers can learn and understand like humans. Natural Language Processing (NLP) is also part of AI and is used in speech recognition and automatic translation. AI is currently being used in various fields, including medicine, autonomous driving, and finance, and is gaining attention. Recent research papers focus on building robots that can walk using self-learning technology by incorporating robotic technology into the propulsion device. It is important to check the latest research papers and reliable sources to learn about AI.

Blockchain

Blockchain has become well known as digital currencies have gained attention. Blockchain is a technology that ensures the reliability of person-to-person transactions and enables secure and decentralized transactions of digital currencies by eliminating the need for central monitoring agencies.

Smart contracts are an additional feature that blockchain provides, automatically executing contract conditions and enabling transactions to take place without third-party involvement.

Research on blockchain is currently focused on addressing authentication and scalability issues to solve common transaction system challenges. Specifically, blockchain is expected to significantly reduce the risk of fraud and illicit transactions.

Trustworthy additional information sources

1) Coin Guide, an information source on blockchain technology and digital currencies 2) Bitcoin News, a website that provides the latest innovations and trends related to blockchain technology 3) Blockchain Research Institute, a research paper that provides in-depth information on new discoveries related to blockchain.

The potential of blockchain is limitless, and it is expected to continue to attract significant attention in the future.

Quantum computer

A quantum computer can solve advanced problems because it operates on a different mechanism than traditional computers. The quantum bit is one of the components of a quantum computer. A quantum bit can take on states not only 0 or 1, but also states in between. Through quantum algorithms, quantum computers can solve optimisation problems and encryption cracking problems.

At present, quantum computer research is being carried out all over the world, and major companies such as Google, IBM, and Microsoft are conducting their own research. The government is also supporting research as a large investment is required. In Japan, institutions such as Nara Institute of Science and Technology, the University of Tokyo, and the National Institute of Informatics are conducting research.

The use of quantum computers is expected to bring innovative results in various fields, such as the development of new medicines, materials science, and artificial intelligence.

As reliable additional information sources, Quantum Computing Report and Quantum Computer Research Association can be listed.

Cloud computing

What is cloud computing? Although this term was first used several decades ago, its existence has recently become widely known to many people. Cloud computing is a technology that can provide processing power remotely over a network, allowing users to save energy and computer resources by not having to perform the processing themselves.

There are three main types of this technology. The first is generally known as public cloud, which is a cloud service for general users provided by well-known providers. Second, if sensitive information needs to be protected, a private cloud is required. This is a cloud environment set up and used exclusively by companies. Finally, there is the hybrid cloud, which combines the strengths of public and private clouds.

The rapid advancement of this technology has dramatically changed system architecture. For example, capacity can be expanded and data can be utilized. Cloud services are becoming increasingly attractive options for businesses.

Current research topics include cloud security, integration of cloud computing, combining cloud computing with artificial intelligence and grid computing. In addition, research is also being conducted on the daily operation and management of cloud services.

To find accurate information sources, it is desirable to consult official academic research papers and industry-specific sites. Along with the rapid growth of cloud services, there are many news articles and technology blogs. However, be sure to check the validity of the information source.

5G network

5G is the fifth-generation mobile communication system, which enables faster and more stable communication than the conventional 4G technology. The communication speed is approximately 100 times faster than traditional mobile phones, and the response time is approximately 10 times faster.

The innovation that 5G brings is remarkable, and it is expected to contribute to the development of technologies in various fields like autonomous cars, smart cities, VR/AR, medicine, among others.

Current research topics and achievements include the development of high- precision location information technology using 5G and the implementation of remote medical care using 5G.

Reliable additional information sources are ITU (International Telecommunication Union) and IEEE (Institute of Electrical and Electronics Engineers).

As shown above, 5G is rapidly evolving, and is expected to have a significant impact on our lives.

Internet of Things (IoT)

The Internet of Things (IoT) is one of the amazing advancements in modern technology. Similar to the normal internet, IoT connects multiple computers and enables the collection and analysis of vast amounts of information through data sharing. IoT has the potential to transform businesses and individual lives by utilising the information collected through IoT devices and sensors.

Currently, research on IoT focuses on areas such as security, privacy and energy efficiency. With real-time data analysis, IoT can identify and improve network and system problems. Furthermore, innovative applications of IoT can be imagined in various fields such as autonomous driving, smart cities, advanced medical equipment, secrecy-protecting security and temperature control systems.

Additional information on IoT can be obtained by referring scientific publications such as IEEE IoT Journal and IoT Insights. Technology-related publications such as Forbes and TechRadar also cover the latest developments in IoT and provide insights about the future of IoT.

Femtosecond laser

A femtosecond laser is a device that generates laser light with extremely short pulses. The laser light oscillates at a repetition frequency of about one trillion times per second, and ultrafast reactions occur due to electronic and nuclear physical phenomena in matter. Its applications are wide-ranging, including material cutting and processing, laser medicine, plasma generation, and quantum optical science. Current research topics include elucidation of new mechanisms and realization of high-power femtosecond laser technology. Reliable additional sources of information include international conferences and academic papers. The potential of femtosecond lasers is unknown, but research is sure to continue in the future.

Nanotechnology

Nanotechnology is a technology that manipulates materials at the atomic and molecular levels. It can be measured in nanometers (nm). Nanotechnology is applied in various fields such as medicine, electronics, environment, energy, and food industry. For example, in the medical field, it is possible to treat cancer, diabetes, and diagnose with biochips. Moreover, nanotechnology is also attracting attention as an eco-technology for producing alternative energy sources for oil and water purification. Current research topics include the synthesis of materials with nanoscale structures and the development of devices using synthesized nanomaterials. Academic journals such as Nature Nanotechnology, ACS Nano, and Journal of Nanoparticle Research are reliable additional sources of information.
