캐싱 알고리즘 동작 확인용 시뮬레이터 설계 및 구현

김우완,천희식 경남대학교 정보통신연구소 1999 연구논문집 Vol.1 No.-

멀티프로세서 시스템을 설계할 경우에는 공유 메모리 구조와 메시지 전달방법이라고 하는 두 가지의 패러다임을 바탕으로 하게 된다. 데이터 분할과 동적 부하 분산 문제를 단순화시킬 수 있으며 확장성을 용이하게 지원하는 장점을 가지고 있는 공유메모리 구조의 멀티프로세서 시스템에서 각 프로세서가 자신의 전용 캐시를 가지는 경우에는 메인 메모리와 이러한 전용 캐시내에 존재하는 데이터 사본간에 일관성 문제가 발생한다. 본 논문에서는 일관성 유지를 위해 제안되어 있는 여러 알고리즘 중 처리 노드와 고대역 저지연 인터커백션 네트워크로 구성되는 공유메모리 구조의 멀티프로세서 프로토타입인 DASH 프로토콜을 지원하기 위한 전용 버스 시스템을 완전 개방형인 IEEE Futurebus+ 스탠다드에 준하여 설계한 다음, 이 시스템이 DASH 프로토콜을 지원하며 캐시의 일관성을 유지하기 위해 필요한 각종 행동과 기존의 범용 버스 시스템이 수행하는 행동의 병렬 처리를 지원한다는 점을 전용 시뮬레이터를 통하여 증명한다. The design of a multi-processor system is based on one of the two approaches: a message-passing mechanism, and a shared-memory architecture[1]. The latter alternative gains an advantage over the former in that it can eliminate problems from the data partitioning and simplify dynamic load balancing so that a system adopting the architecture may be scaled with ease. On the other hand, if a certain shared-memory multiprocessor is allowed to have its own private cache memories, a problem how to keep the consistency between a block in main memory and the copy of the block in a cache shall arise[2][4]. This paper designs and implements a dedicated bus system supporting the DASH protocol, a prototype of a shared-memory multiprocessor consisting of processing nodes and high-bandwidth low-latency interconnection networks, in accordance with the completely open IEEE Futurebus+ Standards. The effectiveness and appropriateness of the bus system are verified through a simulation applied to the DASH protocol. In conclusion, the parallel processing of activities related to cache coherency and those related to existing common bus systems surpass the hardware redundancy induced by the dedicated bus system in performance.

TCP-friendly 혼잡 제어 기법에 관한 연구

김우완,천희식,장상동 慶南大學校 附設 工業技術硏究所 2003 硏究論文集 Vol.21 No.1

멀티캐스트 및 실시간 오디오/비디오 스트리밍 어플리케이션과 같은 새로운 커뮤니케이션 트렌드로 인하여 인터넷상에서 non-TCP 트래픽이 증가하는 추세에 있다. 이러한 어플리케이션은 TCP-friendly기준에 따르는 혼잡 제어를 거의 수행하고 있지도 않으며, 유효 대역폭을 웹 브라우저, FTP, 이메일 클라이언트 등과 같이 TCP를 기반으로 하는 어플리케이션과 공평하게 공유하지도 않는다. 그러므로 지금과 같은 추세로 나아간다면 인터넷은 TCP 트래픽의 Starvation과 Congestion Collapse를 발생시킬 가능성이 높다. 이를 위해 TCP 플로우와의 공존을 지원하는 TCP-friendly프로토콜이 개발되고 있다. 본 논문에서는 TCP friendliness를 위한 현재의 접근 방법을 살펴보고, 각각의 특징을 알아보기로 한다. 그리고 유니캐스트 및 멀티캐스트에 관한 여러 혼잡 제어 프로토콜을 상세히 살펴보기로 한다. Non-TCP traffic on the Internet is on an increasing trend due to new communication patterns such as multicast and real-time audio/video streaming applications. These applications inherently do not perform congestion control in accordance with TCP-friendly standard criteria, nor share valid bandwidth with TCP-based applications like Web Browsers, FTP. E-mail Clients, etc. This means that current drift on the Internet may produce a high possibility of starvation and congestion collapse of TCP traffic. To deal with the unwanted situation such as congestion collapse and starvation, many TCP-friendly protocols supporting non-TCP flows in keeping pace with TCP ones are proposed and still being developed. This paper comprehensively surveys current approaches to TCP-friendliness and their properties in detail in order to systematically aid researches in TCP congestion controls that are the subject of wide attention.

Effect of fenpropathrin on the viability and homing ability of worker bees Apis mellifera

Chun-hua Liao,Jie Wu,Zi-long Wang,Zhi Jiang Zeng,Xiaobo Wu 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.4

To explore the effect of fenpropathrin on survival and homing ability of honeybees Apis mellifera L., the newly emerged honeybee workers (< 12 h old) were randomly divided into 4 groups with 3 replicates in each group. Fenpropathrin (1/2 LD50, 1/4 LD50, 1/8 LD50 and 0% LD50) was added on the thorax of the bees. The viability of worker bees and their homing rate at 1 km distance away from colonies were analyzed, and the expression levels of two memory related genes (GluRA and Nmdar 1) in 20-day–old worker bees were also quantified. Overall, the lifespan and homing rates were significantly decreased with the increase of fenpropathrin dose (P < 0.05), but there was no significant difference between the least group (1/8 LD50) and the control group (0% LD50) (P > 0.05). The relative expression of Nmdar1 was decreased significantly with the increasing doses of fenpropathrin and the lower expression level of Nmdar 1 was found in the fenpropathrin-treaded groups. The expression level of GluRA of workers in 1/8 LD50 group and the control group were significantly higher than that in 1/2 LD50 group and 1/4 LD50 group (P < 0.05), whereas the expression level of GluRA of workers in 1/4 LD50 group was significantly higher than that in 1/2 LD50 group (P < 0.05), and there is no significant difference between 1/8 LD50 group and the control group (P > 0.05). In conclusion, the use of fenpropathrin for agricultural crops may show negative influence on the viability and homing ability of worker bees Apis mellifera L.

Decoupling of the Secondary Saliencies in Sensorless PMSM Drives using Repetitive Control in the Angle Domain

Wu, Chun,Chen, Zhe,Qi, Rong,Kennel, Ralph The Korean Institute of Power Electronics 2016 JOURNAL OF POWER ELECTRONICS Vol.16 No.4

To decouple the secondary saliencies in sensorless permanent magnet synchronous machine (PMSM) drives, a repetitive control (RC) in the angle domain is proposed. In this paper, the inductance model of a concentrated windings surface-mounted PMSM (cwSPMSM) with strong secondary saliencies is developed. Due to the secondary saliencies, the estimated position contains harmonic disturbances that are periodic relative to the angular position. Through a transformation from the time domain to the angle domain, these varying frequency disturbances can be treated as constant periodic disturbances. The proposed angle-domain RC is plugged into an existing phase-locked loop (PLL) and utilizes the error of the PLL to generate signals to suppress these periodic disturbances. A stability analysis and parameter design guidelines of the RC are addressed in detail. Finally, the proposed method is carried out on a cwSPMSM drive test-bench. The effectiveness and accuracy are verified by experimental results.

Wu, Bing-Li,Luo, Lie-Wei,Li, Chun-Quan,Xie, Jian-Jun,Du, Ze-Peng,Wu, Jian-Yi,Zhang, Pi-Xian,Xu, Li-Yan,Li, En-Min Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.12

Background: Fascin, an actin-bundling protein forming actin bundles including filopodia and stress fibers, is overexpressed in multiple human epithelial cancers including esophageal squamous cell carcinoma (ESCC). Previously we conducted a microarray experiment to analyze fascin knockdown by RNAi in ESCC. Method: In this study, the differentially expressed genes from mRNA expression profilomg of fascin knockdown were analyzed by multiple bioinformatics methods for a comprehensive understanding of the role of fascin. Results: Gene Ontology enrichment found terms associated with cytoskeleton organization, including cell adhesion, actin filament binding and actin cytoskeleton, which might be related to fascin function. Except GO categories, the differentially expressed genes were annotated by 45 functional categories from the Functional Annotation Chart of DAVID. Subpathway analysis showed thirty-nine pathways were disturbed by the differentially expressed genes, providing more detailed information than traditional pathway enrichment analysis. Two subpathways derivated from regulation of the actin cytoskeleton were shown. Promoter analysis results indicated distinguishing sequence patterns and transcription factors in response to the co-expression of downregulated or upregulated differentially expressed genes. MNB1A, c-ETS, GATA2 and Prrx2 potentially regulate the transcription of the downregulated gene set, while Arnt-Ahr, ZNF42, Ubx and TCF11-MafG might co-regulate the upregulated genes. Conclusions: This multiple bioinformatic analysis helps provide a comprehensive understanding of the roles of fascin after its knockdown in ESCC.

High Feasibility of Liquid-Based Cytological Samples for Detection of EGFR Mutations in Chinese Patients with NSCLC

Wu, Chun-Yan,Hou, Li-Kun,Ren, Sheng-Xiang,Su, Bo,Chen, Gang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.18

Background: Activating mutations of epidermal growth factor receptor (EGFR) could predict response to tyrosine kinase inhibitor (TKI) treatment in patients with non-small cell lung cancer (NSCLC). However, the detection of EGFR mutation is frequently challenging in clinical practice for the lack of tumor tissue. The aim of this study was to investigate the feasibility of performing EGFR mutation testing on various types of liquid-based cytology (LBC) samples. Materials and Methods: A total of 434 liquid-based cytology samples were collected from March 2010 and November 2013. Among them, 101 with diagnosis of lung adenocarcinoma had paired surgically resected specimens. The ADx Amplification Refractory Mutation System (ADx-ARMS) was used to determine EGFR mutation status both in LBC and resected samples. Results: All liquid-based cytology samples were adequate for EGFR mutation analysis. The mutation rate was 50.5% in the 434 NSCLC patients with LBC samples and the incidence rates of EGFR mutation were consistent among different specimens. We also detected EGFR positives in 52.5% (53/101) patients with paired histologic specimens. The concordance rate of EGFR mutation between LBC samples and paired histologic specimens was 92.1%. Conclusions: Our results suggest that liquid-based cytology samples are highly reliable for EGFR mutation testing in patients with NSCLC.
