Smart Charging of Electric Vehicles
There is a continuous and fast increase in electric vehicles (EVs) adoption in many countries due to the reduction of EVs prices, governments’ incentives and subsidies on EVs, the need for energy independence, and environmental issues. It is expected that EVs will dominate the private cars market in the coming years. These EVs charge their batteries from the power grid and may cause severe effects if not managed properly. On the other hand, they can provide many benefits to the power grid and get revenues for EV owners if managed properly.  This article presents the potential negative impacts of EVs charging on electric power systems mainly due to uncontrolled charging and how through controlled charging and discharging those impacts can be reduced and become even positive impacts through an energy management for electric vehicles.

Hepatic Vessel Skeletonization
Hepatic vessel skeletonization serves as an important means of hepatic vascular analysis and vessel segmentation. Skeletonization provides an effective and compact representation of an image object by reducing its dimensionality to a centerline while preserving the original topologic and geometric properties. Hepatic vascular analysis plays a critical role in the diagnosis and treatment of many liver diseases, classification of liver function regions and inquiry into the nature of vascular growth. Hepatic vessel skeletonization serves as an important means of hepatic vascular analysis, particularly because a hepatic vessel is a kind of thin tubular object satisfying the growth principle of Murray’s law.

Tungsten Inert Gas Welding Process of Dissimilar Metals
Special attention is required when joining two materials with distinct chemical, physical and thermal properties in order to make the joint bond robust and rigid. Welded samples employing ER-309L filler wires had a microstructure consisting of a delta ferrite network in an austenite matrix. The tensile strength experimental results revealed that welding current, followed by GFR, was a highly influential parameter on tensile strength. Weld metals had higher hardness and flexural strength than stainless steel and carbon steel base metals.

Sensors Used on Fabric-Handling Robots
Fabric-handling robots could be used by individuals as home-assistive robots. While in most industries, most processes are automated and human workers have either been replaced by robots or work alongside them, fewer changes have occurred in industries that use limp materials, like fabrics, clothes, and garments, than might be expected with today’s technological evolution. Integration of robots in these industries is a relatively demanding and challenging task, mostly because of the natural and mechanical properties of limp materials.

Finite Element Analysis for Studying Knee Osteoarthritis
Osteoarthritis (OA) is a degenerative disease that affects the synovial joints, especially the knee joint, diminishing the ability of patients to perform daily physical activities. Finite element analysis (FEA) has been considered a promising computational method to be developed for knee OA management. The FEA pipeline consists of three well-established phases: pre-processing (to prepare the model), processing (to solve the mathematical problem), and post-processing (to analyze the results). Each of these phases requires extensive expertise to conduct them properly, as there exist several different approaches with selection-specific limitations.

Industry 6.0 and Their Implementation in AEC Sector
The Architecture, Engineering, and Construction (AEC) Industry 6.0 is the sixth transformative phase of the architectural, engineering, and construction sector, built on Industry 5.0. Industry 6.0 pioneers advancements in quantum computing, nanotechnology, artificial intelligence, and cloud-based energy solutions. Harmonization facilitates design, building, and maintenance processes, improving efficiency, accuracy, and sustainability. Construction has changed, like the 5.0 framework. Industry 5.0 uses AI and robotics to boost productivity, creativity, and supply chain alignment.

F-X (Japan)
The F-X (unofficially called F-3) is a sixth-generation stealth fighter in development for the Japan Air Self-Defense Force (JASDF). It is Japan's first domestically developed stealth fighter jet and will replace the Mitsubishi F-2 by the mid–2030's. Its development is to also bolster the nation's defense industry and potentially enter the international arms market amid Japan's change in defense posture. The F-X has been nicknamed the "Godzilla" fighter owing to its large size, as well as a nod to the popular Kaiju.

Radar Gun
A radar speed gun (also radar gun and speed gun) is a device used to measure the speed of moving objects. It is used in law-enforcement to measure the speed of moving vehicles and is often used in professional spectator sport, for things such as the measurement of bowling speeds in cricket, speed of pitched baseballs, athletes and tennis serves. A radar speed gun is a Doppler radar unit that may be hand-held, vehicle-mounted or static. It measures the speed of the objects at which it is pointed by detecting a change in frequency of the returned radar signal caused by the Doppler effect, whereby the frequency of the returned signal is increased in proportion to the object's speed of approach if the object is approaching, and lowered if the object is receding. Such devices are frequently used for speed limit enforcement, although more modern LIDAR speed gun instruments, which use pulsed laser light instead of radar, began to replace radar guns during the first decade of the twenty-first century, because of limitations associated with small radar systems.

Constructed Wetlands as a Sustainable Sanitation Solution
The application of nature-based solutions (NBSs) in treating wastewater are treatment wetlands or constructed wetlands (CW). CWs are natural treatment technologies that efficiently treat many different types of wastewater (domestic wastewater, agricultural wastewater, coal drainage wastewater, petroleum refinery wastewater, compost and landfill leachates, fish-pond discharges, industrial wastewater from pulp and paper mills, textile mills, seafood processing). CWs can effectively treat raw wastewater to different levels of treatments and can be used as a primary, secondary, or tertiary treatment. CWs are engineered systems designed to optimize and copy processes found in natural environments thus they are considered as sustainable, environmentally friendly options for wastewater treatment. CWs have low operational and maintenance requirements and have a stable performance with less vulnerability to inflow variation. CWs have proved their ability to treat several types of wastewaters. Several benefits and facts, such as the low construction and operational costs of CWs, low-energy, and less operational requirements, have raised the interests in CWs as a treatment technology. The sustainability of CWs as a sanitation solution (technical, financial, environmental sustainability) is described with a focus on integrating climate change resilience and a circular economic approach to the technical and financial sustainability.

Particulate Matter Generation and Mitigation in Poultry Houses
Poultry farming plays a key role in agricultural air emissions. Particulate matter (PM) level tends to be high in broiler and cage-free layer houses, that may impair health and welfare of animals and their caretakers. To protect public health and welfare, the occupational exposure limit for PM10 and PM2.5 (i.e., PM diameters that are generally ≤10 and 2.5 μm, respectively) are suggested not to exceed 150 µg m−3 and 35 µg m−3, respectively, based on 24-h concentrations thresholds as suggested by US. EPA. However, the levels of PM10 and PM2.5 in poultry houses could be 100 times higher than that limit. Generally, PM emissions are affected by various factors, including housing types, seasonal and diurnal variation, manure management, bedding materials, ventilation rates, and birds’ activities. High PM concentrations in poultry houses impair birds’ and caretakers’ liver, kidneys, and respiratory systems. Effective mitigation strategies include frequent house cleaning, optimum light intensity, liquid spraying, bedding management, and air filtration systems. However, mitigation strategies can be cost-prohibitive and have side effects. Therefore, poultry farms should select mitigation strategies based on farm location, climate conditions, environmental policies, and available resources (government assistance programs).
