A data-base of the advanced multi-material joint performance has to be prepared for designing a future multi-material car body in order to select both the advanced materials and the joining methods appropriately. In this research, as one of the most important joint performances, the tensile fatigue properties of dissimilar lap joints were studied. Various advanced multi-material dissimilar lap joint using an ultra-high strength steel (UHHS), a carbon fiber reinforced thermo-plastic (CFRTP) and an aluminum alloy of A5083P-O were fabricated by the resistance spot welding (RSW), refill friction stir spot welding (RFSSW), friction stir spot welding (FSSW) and laser irradiation assistance plastic welding (LIAPW). Regardless of the types of dissimilar materials, it is found that the number of cycle achieving to the fracture decreases almost monotonically with increasing the applied load. In addition, the shear fatigue properties of UHHS & A5083P-O joint joined by RFSSW is found to be similar to that of aluminum alloy joint joined by RSW. Moreover, the fatigue properties of UHHS & CFRTP and A5083P-O & CFRTP joints made by FSSW are revealed to be governed by the interfacial strength between the metals and CFRTP and to be predicted by the tensile shear strength of the dissimilar lap joint. © 2023 Japan Welding Society.

In order to design a future multi-material car body, both an appropriate selection of the advanced materials and a suitable assignment of joining methods are essential technologies, where the data-base of the advanced multi-material joint performance has to be prepared. In this research various advanced multi-material dissimilar lap joints were fabricated and the tensile shear strength of those joints was evaluated. The materials used were an ultra-high strength steel (UHHS), a carbon fiber reinforced thermo-plastic (CFRTP) and an aluminum alloy of A5083P-O. The resistance spot welding (RSW) and refill friction stir spot welding (RFSSW) were employed for joining UHHS and A5083P-O, while UHHS & CFRTP and A5083P-O & CFRTP lap joints were fabricated by the friction stir spot welding (FSSW) and laser irradiation assistance plastic welding (LIAPW). The tensile shear strength of UHHS & A5083P-O joint joined by RFSSW was found to be almost two times of that produced by RSW, and this difference seems to be mainly caused by the difference of joint area. The difference of joint area also affects the tensile shear strength of UHHS & CFRTP or A5083P-O &CFRTP lap joints made by FSSW and LIAPW, and the joint strength of LIAPW was larger than that of FSSW. Moreover, all the tensile shear tests suggest that the total heat input during joining process might not influence the tensile shear strength proportionally and the relationship between the joining conditions and tensile shear strength has be evaluated by using the artificial intelligence technologies in order to contribute the data-base of the advanced multi-material joint performance. © 2023 Japan Welding Society.

One of the challenges of road safety is the uncertainty in deciding whether to continue crossing or to stop at an intersection during yellow or amber light signal. The issue arises from the dilemma zone when approaching a yellow light, often caused by insufficient yellow interval duration when using the road speed limit derived from the 85th-percentile of the recorded speeds of vehicles crossing in the kinematic equation computation, whereas the actual speed of crossing vehicles is often greater than the speed limit. This work demonstrated the ability of the developed Computer Vision based algorithm to determine the kinematic equation's optimum yellow interval duration by using object tracking to derive the approach speed of the test vehicles. It was concluded that the computer vision algorithm and the ground truth from the vehicle's speedometer are functionally congruent and there was no statistically significant difference between the outputs of the two methods with the variance attributed to normal distribution error. © 2023 IEEE.

Road safety is a major concern, in which technologies can help provide solutions. In this paper, a road safety information exchange and traffic control system were developed based on data-driven technologies and wireless communications with focus on two road safety use cases: Emergency Response Vehicle (ERV) prioritization and over speeding. An intelligent traffic controller equipped with a Variable Message Signboard (VMS) and Wireless Access Point (WAP) for communication of road safety messages, and an On-Board Unit (OBU) mounted on a vehicle, were developed, and applied to the two use cases. It was found that the system can communicate safety messages related to over speeding and ERV prioritization to motorists using the MQTT protocol over Wi-Fi and using a VMS for visual communication. Aside from road safety, the system can use road information to actuate traffic control. © 2023 IEEE.

Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) possess the intrinsic ability to differentiate into diverse cellular lineages, marking them as potent instruments in regenerative medicine. Nonetheless, the proclivity of these stem cells to generate teratomas post-transplantation presents a formidable obstacle to their therapeutic utility. In previous studies, we identified an array of cell surface proteins specifically expressed in the pluripotent state, as revealed through proteomic analysis. Here we focused on EPHA2, a protein found to be abundantly present on the surface of undifferentiated mouse ESCs and is diminished upon differentiation. Knock-down of Epha2 led to the spontaneous differentiation of mouse ESCs, underscoring a pivotal role of EPHA2 in maintaining an undifferentiated cell state. Further investigations revealed a strong correlation between EPHA2 and OCT4 expression during the differentiation of both mouse and human PSCs. Notably, removing EPHA2+ cells from mouse ESC-derived hepatic lineage reduced tumor formation after transplanting them into immune-deficient mice. Similarly, in human iPSCs, a larger proportion of EPHA2+ cells correlated with higher OCT4 expression, reflecting the pattern observed in mouse ESCs. Conclusively, EPHA2 emerges as a potential marker for selecting undifferentiated stem cells, providing a valuable method to decrease tumorigenesis risks after stem-cell transplantation in regenerative treatments.

In these days, construction sites are facing workforce shortages caused by declining labor and lack of young workers. Therefore, "Improve Productivity" is very important. Automation and autonomy of construction machinery is one of the solutions. As above, ICT hydraulic excavators and bulldozers are widely used in many sites, but the scope of the application is limited. In particularly, automated excavating in hydraulic excavators still has many difficulties in actual use. The root cause is needed to the complicated operation during excavation affected by the soil conditions. Since the soil conditions change anytime, if the operation is not adjusted to match to them, the efficiency will be decreased significantly. In other words, to achieve automated excavating, the hydraulic excavator must recognize variation of soil conditions first. While digging, the operator has been sensing the machine's response affected by the soil conditions to consider it and adjusting machine operation simultaneously. In other words, human senses were used to recognized soil conditions to perform efficient operations. In that case, we thought that if we could replace human senses with internal sensors of the machine, the machine could recognize the soil conditions by itself. In this study, based on this hypothesis, we conducted measuring sensor data during excavating in various soil conditions (e.g. hardness, materials…). The test results indicated that the soil hardness measured by simplified N-value meter, has a high correlation with the work efficiency and bucket tooth speed calculated from internal sensor data. This implicated that the sensor data from the hydraulic excavator can be used to be determine soil conditions. In addition, there is a possibility that excavator could recognize soil conditions by itself. © 2024 International Society for Terrain-Vehicle Systems. All rights reserved.
