Effect of Mold Flux Containing Ce2O3 on the Contents of Aluminum, Silicon, and Titanium in Incoloy825 Super Alloy by Geng Xin, Boyang Li, Zhouhua Jiang, Hou Yu

“…Firstly, the activity model of the CaO-SiO2-Al2O3-Na2O-MgO-CaF2-Ce2O3 slag system was established according to the ion and molecule coexistence theory (IMCT), and the calculation results show that with the increase of Ce2O3 content in the mold flux, the activity of Al2O3 decreases significantly and the activity of SiO2 decreases and gradually tends to 0. …”

INVESTIGATION ON THE DYNAMICS OF MOVEMENT OF CYLINDRICAL CLEANING PIGS THROUGH THE BENDS OF PIPELINE SYSTEMS FOR FLUID TRANSPORTATION by Serhii STETSIUK, Yaroslav DOROSHENKO, Robert BONDARENKO, Oleksandr FІLIPCHUK, Volodymyr VOLOVETSKYI

“…Contact forces of normal reaction, arising due to pig bending in the pipeline bend and determining the magnitude of frictional force between the pig and the inner wall of the bend, were determined based on classical bending theory. The impact of the material's modulus of elasticity, from which the pig is made, on the magnitude of contact forces of normal reaction at the pig pressing points against the inner wall of the pipeline bend was established. …”

Person Reference in Iranian Sistani Narrative Texts by Farideh Okati

“…The result shows that, apart from the frequent usage of proper noun for emphasis, the anaphoric zero has the highest range of occurrence and is the highest accessible marker in the context, and this violation, relating the ‘government and binding’ theory of Chomsky (1981), occurs because the discontinuity conditions, such as end of the clause-chain, does not force the anaphoric pronoun or proper noun to be used where they are expected to be. …”

Social network user geolocating method based on weighted least squares by Wenqi SHI, Xiangyang LUO, Jiashan GUO

“…When providing location-based dating and other location-based services, social networks will confuse the displayed user distance text to protect the user’s location privacy.In order to verify whether the current location confusion mechanism adopted by social networks can effectively protect user’s accurate location, a social network user geolocating method based on weighted least squares was proposed.The method constructed real-world tests to collect a large number of confused distance texts in location dating service, and identified the real distance boundary of reported distance combined with real distance data.Then, based on the discrimination of the quadrant of the coordinate system where the target user was located, the position of probes was optimally deployed, and multiple preliminary position estimations of the target user were obtained by using the trilateration model.The weights of the longest and the shortest distance of the target user were determined by the estimated position, and the related objective function was constructed.The optimal solution of the objective function was calculated based on the weighted least squares, which was the final geolocating result of the target user.The proposed method inferred the location of social network user based on the distance boundary constraint, which avoided the frequent query of location services and ensured the geolocating efficiency.The actual geolocating results based on 500 WeChat users showed that, the proposed method can accurately geolocate the “eople nearby” users of WeChat.Compared with the existing typical geolocating methods based on space partition and heuristic number theory, the proposed method have better performance in geolocating accuracy and efficiency.The average geolocating error is reduced by more than 10%, and the number of location service quarries in the geolocating process is reduced by more than 50%.…”
