A new advanced scanning technique has been developed to analyze confiscated iron artifacts, allowing researchers to gain insights into their origins and manufacturing processes. This method enhances the understanding of historical metalwork and supports archaeological studies for Iranian Iron Age artifacts (3000 B.C.). #Ironage #iran #metalwork https://lnkd.in/gT3RKZWk

According to the article, axial flux electric motors, such as the one patented by General Motors, have a distinctive disc-shaped design that distinguishes them from more common radial flux motors. This design allows for a higher power density and torque output in a more compact package. Specifically, the article notes that axial flux motors can generate high torque at low speeds, which could potentially eliminate the need for multi-speed transmissions in electric vehicles. This is because the motor's high torque output across a wide speed range can mimic the functionality of traditional geared transmissions, providing the desired torque and acceleration without the need for complex shifting mechanisms. In traditional internal combustion engine vehicles, the transmission and gearing system are crucial for matching the engine's torque curve to the vehicle's needs. However, electric motors inherently have a flatter torque curve that extends across a wide speed range. https://lnkd.in/g22TFXxx

Based on the information provided in the article, it seems that Toyota, Mazda, and Subaru are taking a cautious and measured approach to the adoption of electric vehicles. While the industry as a whole is moving towards greater electrification, these companies appear to be waiting for the technology and infrastructure to mature before making significant investments in EVs. Their decision to focus on hybrid and traditional vehicles in the meantime may be a strategic move to maintain competitiveness and profitability in the short-term, while positioning themselves for a potential shift towards EVs in the future. However, this approach also carries risks, as they may fall behind competitors who are more aggressively pursuing EV technology. Ultimately, the success or failure of this strategy will depend on a variety of factors, including the pace of technological advancements, changes in consumer preferences, and the evolution of regulatory environments around the world. It will be interesting to see how these companies navigate the shifting automotive landscape in the coming years. #ev #hev #ICE https://lnkd.in/g476JBnc

The Parthians were an ancient Iranian civilization that ruled a vast empire in the Middle East from the 3rd century BC to the 3rd century AD. 1. The Parthians' political and cultural influence, as they were able to establish a powerful empire that rivaled the Roman Empire. 2. The Parthian's advancements in architecture and art and the adoption of Hellenistic influences. 3. Their historical obscurity can be attributed to limited written records and the dominance of Greek and Roman histories in Western scholarship. 4. Modern interest in ancient Middle Eastern empires is gradually increasing, shedding more light on the significant impact of the Parthians in resisting one of history’s most powerful empires. #Persian #Iran https://lnkd.in/g8if8tuF

The article discusses a dispute between Geely and BYD over the claim of having the world's most thermally efficient engine. This dispute arose after BYD announced its fifth generation DM (PHEV) technology, which raised questions about the three main claims and how they are measured. Geely is not happy with BYD's claim and has engaged in a spat over who actually has the most efficient engine. The article also mentions the launch of BYD's fifth generation DM technology and the unveiling of the first two cars to use it, the Qin L DM-i and the Seal 06 DM-i, at a press conference. Key information from the press conference includes BYD's claims of achieving the highest engine thermal efficiency, lowest fuel consumption, and longest comprehensive range. The article also touches on the specifications of the new PHEV system and the potential impact of the dispute on the companies involved.
