Small Bowel Capsule Endoscopy
Small bowel capsule endoscopy (SBCE) is one of the most useful methods for diagnosing small bowel lesions. When a pill-like capsule endoscope is swallowed, the camera of the capsule endoscope captures the small bowel mucosa. Although it is a noninvasive endoscopy, it has the disadvantage of long reading time. To solve this problem, artificial intelligence (AI) algorithms for SBCE reading are being actively studied. The main goal is to quickly and accurately detect small bowel lesions using an AI algorithm trained on images of lesions. This content briefly summarizes the use of AI algorithms for SBCE reading.

ITO Electrodes
The very common electrode in the LC cells, i.e., ITO, is well known for its refractive index modulation property. In the regimes of low addressed electrostatic potential and visible optical power, it can act quite semiconducting due to the charge carriers’ redistributions with a low density in the laser beam spot. A challenge was the understanding of the sources of the SPR effect in the NLC cells; it was found that the electron-hole-pair production and subsequent transport can happen in the ITO thin layer in addition to the orientant, where the residing charge carriers in the beam spot can be effectively neutralized due to the photo-induced low conductivity. In the semiconducting operating mode of the ITO layer, a fringe electric field with its tangent element to the LC confining surfaces (equipped with ITO) was induced which results in the LC director field realignment parallel to the cell surfaces (irrespective of the sign of the dielectric anisotropy), hence the SPR effect.

ML-Based Classification Algorithms for SCIM
In industry, electric motors such as the squirrel cage induction motor (SCIM) generate motive power and are particularly popular due to their low acquisition cost, strength, and robustness. Along with these benefits, they have minimal maintenance costs and can run for extended periods before requiring repair and/or maintenance. Early fault detection in SCIMs, especially at low-load conditions, further helps minimize maintenance costs and mitigate abrupt equipment failure when loading is increased.

Power Line Communication Technology
Power line communication (PLC) is a technology that exploits existing electrical transmission and distribution networks as guiding structures for electromagnetic signal propagation. This facilitates low-rate data transmission for signaling and control operations. As the demand in terms of data rate has greatly increased, the attention paid to broadband PLC (BPLC) has also greatly increased. This concept also extended to railways as broadband traction power line communication (BTPLC), aiming to offer railway operators an alternative data network in areas where other technologies are lacking.

Network Slicing in 5G
As the idea of a new wireless communication standard (5G) started to circulate around the world, there was much speculation regarding its performance, making it necessary to carry out further research by keeping in view the challenges presented by it. 5G is considered a multi-system support network due to its ability to provide benefits to vertical industries.Due to the wide range of devices and applications, it is essential to provide support for massively interconnected devices. Network slicing has emerged as the key technology to meet the requirements of the communications network. In this paper, we present a review of the latest achievements of 5G network slicing by comparing the architecture of The Next Generation Mobile Network Alliance’s (NGMN’s) and 5G-PPP, using the enabling technologies software-defined networking (SDN) and network function virtualization (NFV). We then review and discuss machine learning (ML) techniques and their integration with network slicing for beyond 5G networks and elaborate on how ML techniques can be useful for mobility prediction and resource management. Lastly, we propose the use case of network slicing based on ML techniques in a smart seaport environment, which will help to manage the resources more efficiently.

Energy Management Systems in Microgrids
Microgrids usually employ distributed energy resources such as wind turbines, solar photovoltaic modules, etc. When multiple distributed generation resources with different features are used in microgrids, managing these resources becomes an important problem. The generated power of solar photovoltaic modules and wind turbines used in microgrids is constantly changing with solar irradiation and wind speed. Due to this impermanent and uncertain nature of renewable energy resources, generally, energy storage systems are employed in microgrid systems. To control the distributed energy resources and energy storage units and sustain the supply and demand balance within the microgrid and provide sustainable and reliable energy to the loads, energy management systems are used. Many methods are used to realize and optimize energy management in microgrids.

Framework of Efficient Energy Management System
The traditional power system is inefficient because it entirely depends on fossil fuels, and having centralized generation that is far away from consumers. In these circumstances, the generated electricity needs to be transmitted and distributed to consumers via transmission and distribution lines over long distances, spending many resources on construction, maintenance of all systems involved and high levels of technical losses. In smart grid, energy management is an indispensable for reducing energy cost of consumers while maximizing user comfort and alleviating the peak to average ratio and carbon emission under real time pricing approach.

Load Frequency Control Considering Renewable Energy Sources
The hybrid power system is a combination of renewable energy power plants and conventional energy power plants. This integration causes power quality issues including poor settling times and higher transient contents. The main issue of such interconnection is the frequency variations caused in the hybrid power system. Load Frequency Controller (LFC) design ensures the reliable and efficient operation of the power system. The main function of LFC is to maintain the system frequency within safe limits, hence keeping power at a specific range. An LFC should be supported with modern and intelligent control structures for providing the adequate power to the system.

Artificial Intelligence in Microgrid Control and Safety
Cyber attacks in microgrid systems not only cause issues with data integrity and confidentiality, but cause huge economic losses. Communication of sensor and operational data between each node is essential to attain the efficient operation of microgrid systems. Therefore, monitoring and analyzing the data continuously plays a major role in attaining data integrity. This becomes challenging when the attack is made at the device level rather than the network level. In this scenario, the basic network-level security used in the classical CPS fails to identify the attacks.  Artificial Intelligence (AI) can detect and mitigate cyber attacks.
