This paper discussed the coarsening behavior of the γ′ phase in Waspaloy during heat treatment at different aging timesunder the temperatures of 960 °C and 1000 °C. The morphology of γ′ phase is obtained by scanning electron microscopyand it is measured by the software Image Pro Plus 6.0 in a variety of aging conditions. The volume fraction of the γ′ phase isdecreasing with the increase of the temperature. The radius of the γ′ phase is subject to involve the coarsening process duringaging treatment, and the coarsening rate decreases with the extension of the aging time at certain temperature. Besides,the coarsening kinetics of γ′ phase in Waspaloy is adequately characterized by the Lifshitz–Slyozov–Wagner (LSW) theorymodel as the particle size distribution and coarsening behavior show excellent agreement with the LSW model. Accordingto the experimental results and LSW model, the coarsening rate coefficients were determined to be 27.23 nm3/s and58.67 nm3/s under the aging temperature of 960 °C and 1000 °C respectively. Meanwhile, on the basis of the experimentalstatistics analysis and the LSW model, the mathematical model of the coarsening behavior of the γ′ phase in Waspaloy wasdeveloped. Mathematical model developed in this paper can be used to evaluate the coarsening process of the γ′ phase duringthermal exposure. The interfacial energy between the γ′ phase and the γ matrix was determined to be 56.04 mJ/m2 and44.27 mJ/m2 at the temperature of 960 °C and 1000 °C respectively.

Numerical investigation on cooling performance of pulsating flow in a ribbed channel

Wei Wang,Yang Gao,Genwei Wang,Haiping Tian 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.4

The gas turbine vanes have to withstand the impact of the high temperature gas and keep working in this high temperature which is much higher than the metal melting point. For this reason, these vanes need effective cooling. The traditional coolant is the steady state air flow, whose cooling performance is not satisfied to some extent. The pulsating flow may have better cooling performance due to its more complicated flow characteristics. This paper performs a numerical study to investigate the cooling performance of pulsating flow for the internal convection cooling of the vane. The geometric model is a heated rectangular duct with rib turbulators cast on its internal surfaces. This rectangular duct has different geometric parameters such as different rib spacing (P/e) and channel width to height ratio (W/H). Also, the coolant pulsating flow has three different flow patterns (triangular wave, square wave and sinusoidal wave). Studies show that the pulsating frequence (fv), pulsating amplitude (A) and Reynolds number (Re) are the most immediate parameters characterizing the flow and heat transfer of the pulsating flow. The numerical results of the pulsating flow have been analyzed and compared with the steady flow.

拓展港口功能 發展城市經濟

왕해평(Wang Haiping) 한국항만경제학회 1994 韓國港灣經濟學會誌 Vol.10 No.-

The superiority of a port city is that, it can work as a hub of communications joining land traffic with sea borne traffic and joining domestic market with foreign market, and it can also work as a link in multiple transportation network. The development of a port will result in the change of industrial structure and make the port multi-functional at the same time, creating vast space for the development of the industrial structure. As a result, products can reach consumers more rapidly, cheaply, efficiently and safely and the port can thus become more internationalized and informative. Therefore, it is very demanding for Tianjin to take the advantage of the superiority of its port in order to further widen its openness to the outside world, make full use of both domestic market and foreign market and actively take part in international competition and cooperation as well as to achieve the rejuvenation of Tianjinls economy to expedite Tianjin's development.

Ciphertext-Policy Attribute-Based Encryption with Hidden Access Policy and Testing

( Jiguo Li ),( Haiping Wang ),( Yichen Zhang ),( Jian Shen ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.7

In ciphertext-policy attribute-based encryption (CP-ABE) scheme, a user`s secret key is associated with a set of attributes, and the ciphertext is associated with an access policy. The user can decrypt the ciphertext if and only if the attribute set of his secret key satisfies the access policy specified in the ciphertext. In the present schemes, access policy is sent to the decryptor along with the ciphertext, which means that the privacy of the encryptor is revealed. In order to solve such problem, we propose a CP-ABE scheme with hidden access policy, which is able to preserve the privacy of the encryptor and decryptor. And what`s more in the present schemes, the users need to do excessive calculation for decryption to check whether their attributes match the access policy specified in the ciphertext or not, which makes the users do useless computation if the attributes don`t match the hidden access policy. In order to solve efficiency issue, our scheme adds a testing phase to avoid the unnecessary operation above before decryption. The computation cost for the testing phase is much less than the decryption computation so that the efficiency in our scheme is improved. Meanwhile, our new scheme is proved to be selectively secure against chosen-plaintext attack under DDH assumption.

3차원 정보로부터 정확한 에지를 추출하고 푸리 변환하여 물체를 인식할 수 있는 고 효율의 물체 인식방법을 제안하였다. 물체의 윤곽은 인식에 유용한 많은 정보를 포함하고 있지만, 정확한 윤곽정보를 얻기가 어려우며, 정확한 윤곽정보를 얻었다고 하더라도 물체의 크기나 방향 마다 윤곽이 달라지기 때문에 물체 인식에 획기적 대안으로 활용되지 못하고 있다. 제안한 물체 인식 알고리즘은 1) 레이저 스캔 디바이스를 사용하여 얻는 3 차원 물체정보로부터 정밀한 물체 윤곽을 획득하고 2) 크기 및 회전 불변한 푸리에 표시 자를 이용하여 윤곽을 표현함으로써, 필요 데이터 베이스의 크기를 대폭 줄인다. 이렇게 얻어진 물체에 대한 푸리에 표식자 정보는 미리 준비된 푸리에 표식자 데이터 베이스로부터 최적 정합되는 물체를 찾아 인식한다. 이 알고리즘은 MPEG7 Part B의 방대한 영상 데이터 베이스를 대상으로 실험하였으며, 그에 대한 결과를 논문에 포함시켰다. A high performance object recognition algorithm using Fourier description of the 3D information of the objects is proposed. Object boundaries contain sufficient information for recognition in most of objects. Howeveer, it is not well utilized as the key solution of the object recognition since obtaining the accurate boundary information is not easy. Also, object boundaries vary highly depending on the size or orientation of object. The proposed object recognition algorithm is based on 1) the accurate object boundaries extracted from the 3D shape which is obtained by the laser scan device, and 2) reduction of the required database using the size and rotational invariant feature of the Fourier Descriptor. Such Fourier information is compared with the database and the recognition is done by selecting the best matching object. The experiments have been done on the rich database of MPEG 7 Part B.

Background: The dysregulation of LncRNAs is related to the malignant progression of many cancers. Objective: The study aimed to investigate the expression and the biological role of LncSNHG3 in hepatocellular carcinoma (HCC). Methods: The TCGA data of the LncSNHG3 in HCC were analyzed. The expression in HCC cell lines was detected by qRT-PCR. Proliferation, migration, and invasion of HepG2 and Huh7 were examined by cell counting kit-8, colony formation, transwell assays, and wound healing assays. At the same time, the interactions among LncSNHG3, miR-152-3p, and JAK1 were confirmed by dual-luciferase reporter assay, RNA immunoprecipitation, subcellular distribution. Xenograft tumor-bearing mice models were used to measure the effect of LncSNHG3 on the growth of HCC in vivo. The apoptosis and epithelial mesenchymal transition (EMT)-associated proteins were checked by WB and IHC. Results: LncSNHG3 was overexpressed in HCC tissues and cell lines. In addition, it is correlated with the tumor stage and survival time of HCC patients. Down-regulated LncSNHG3 could significantly suppress the EMT progression of HCC in vivo and in vitro. LncSNHG3 could promote the JAK1 expression by sponging miR-152-3p. Conclusions: LncSNHG3 acted as an oncogene and promoted the EMT procession in HCC by binding miR-152-3p and promoting JAK1 expression. Predictably, LncSNHG3 was used as a potential marker and will be used as a novel therapy target for HCC in the future.
