Research of Power Battery Management System in Electric Vehicle
Yinquan Hu,Xiaobing Wu,Jianshan Tu,Qiheng Fan 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.2
Power battery management system is a very important part in electric vehicle. Currently, power battery management system is only monitor and control of the power batteries group voltage. This may cause a single battery over-charge and over-discharge, thus affecting cycle life of the power battery. In this paper, for each cell in the batteries group is monitored and controlled to prevent any battery over-charge and over-discharge. Hardware and software of power battery management system has been designed. Experimental results show that power battery management system can accurately monitor the power batteries, thereby ensuring the safety of the power batteries and prolonging the cycle life of the power batteries group.

Background/Aims: Epstein-Barr virus-associated gastric cancers (EBVaGCs) have unique molecular and clinicopathological characteristics. The cyclic GMP-AMP synthase-stimulator of interferon genes (STING) pathway is recently recognized as the critical innate immunity against pathogens and tumors. STING is also a master regulator in the cancer-immunity cycle and targeting STING could synergize with existing immune-checkpoint therapies. However, the role of STING in GC, especially in EBVaGC, and its correlation with programmed death-ligand 1 (PD-L1) remain largely unclear. Methods: We collected 78 cases of EBVaGCs and 210 cases of EBV-negative GC (EBVnGC) from a total of 1,443 cases of GC analyzed by EBV-encoded small RNA in situ hybridization. We investigated STING and PD-L1 expression and their concomitant prognostic value in EBVaGCs and EBVnGCs using tissue microarray and immunohistochemistry. The effects of STING and PD-L1 expression on the overall survival of patients with EBVaGC or EBVnGC were assessed by univariate and multivariate analysis. Results: We found that both STING and PD-L1 exhibited significantly higher expression in the EBVaGCs than that in the EBVnGCs. The expression of STING was positively correlated with that of PD-L1 in EBVaGCs. Simultaneous negative expression of STING and PD-L1, and positive expression of STING were independent prognostic risk factors for EBVaGC and EBVnGC, respectively. Conclusions: This is the first prognostic retrospective study of STING and PD-L1 expression and the prognosis among EBVaGC and EBVnGC. The expression and prognostic value of STING and PD-L1 are different in the two types of GCs. STING and PD-L1 are promising prognostic biomarkers and therapeutic targets for EBVaGC and EBVnGC.

Heping Hang,Juan Song,Fang Yang,Xiaobing Fan 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
The design of digital temperature transmitter based on microcontroller ADuC824 is introduced. With the peripheral feature integrated in microcontroller ADuC824 the hardware is simplified and reliability is improved. The interface of thermocouple with A/D converter in ADuC824 and RS232 interface with master computer is presented. The non-linear compensation and cold-junction compensation of thermocouple is provided.
