To help you in writing an LL grammar, we have developed a tool to analyze a grammar and determine if it is LL(1). A jar file containing the class files can be downloaded here. Place this jar file in your class path before running the analyzer. LLanalyze requires JDK 1.2. In the CSUGLAB, use g:\jdk1.2.2\bin\java (NT) or /usr/local/jdk1.2.1 (Solaris). You can also look at the source code for LLanalyze. JLex is required to build it.

在航電系統(tǒng)維護(hù)過(guò)程中，為解決定位故障的效率和降低維修成本等問(wèn)題，提出了基于ICD（Interface Control Document，接口控制文件）的1553B總線的信息監(jiān)控系統(tǒng)模型。該系統(tǒng)運(yùn)用數(shù)據(jù)采集卡對(duì)總線中傳輸?shù)男盘?hào)有無(wú)失真、偏差等電氣特性進(jìn)行檢測(cè)，并使用1553B通訊卡通過(guò)測(cè)控軟件LabWindows/CVI編程與ICD數(shù)據(jù)庫(kù)的動(dòng)態(tài)鏈接，實(shí)現(xiàn)總線信息的解析和故障的判斷。與傳統(tǒng)的維護(hù)過(guò)程相比，這種模型能夠從信號(hào)的電氣特性以及信息的解析等全方位的去檢測(cè)判斷故障的來(lái)源，并且能夠廣泛在其他1553B總線系統(tǒng)內(nèi)擴(kuò)展應(yīng)用。驗(yàn)證表明該監(jiān)控系統(tǒng)可以對(duì)總線信息進(jìn)行快速有效地監(jiān)測(cè)分析，能滿足應(yīng)用需求。 Abstract: In the process of avionics system maintenance， to solve the problems such as improving the efficiency of fast orientation to troubles and reducing maintenance cost， system of 1553B bus information monitor model based on ICD was proposed. The system observed whether the data which transmitted on the bus appear distortion and deviation by using data acquisition card. And using 1553B communication card programming of the measure software LabWindows/CVI and the dynamic linking of ICD database， message analysis and fault estimation could be realized. Compared with traditional maintenance， this model can all-dimensionally detect and analyze the source of faults from both electrical characteristics of the signal and message analysis， and it can be widely applied in the other 1553B system. Experiment shown that this monitor system can effectively detect and analyze the bus message and can meet the application requirements.

Expert Choice represents a significant contribution to the decision making process 工t assists a decision maker in solving complex problems involving many criteria and several courses of action . An Expert Choice solution to a problem reflects the expertise of the decision maker , not the computer . Behavioral scientists have spent many years studying the human mind and how it makes decisions . They have found that humans are influenced by their previous experiences and this causes them to have biases . Basic instincts , preferences and environmental factors also play key roles in how we analyze data and make decisions . There 15 way to remove these factors from human decision making , nor would we necessarily want to , but as the problems of our world become more and more complex , it 15 necessary for us to employ a framework to help make more logical and less biased decisions while still taking our feelings and intuition into consideration .

三維矢量有限元-矩量法電磁場(chǎng)分析程序。 EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.

Fast settling-time added to the already conflicting requirements of narrow channel spacing and low phase noise lead to Fractional4 divider techniques for PLL synthesizers. We analyze discrete "beat-note spurious levels from arbitrary modulus divide sequences including those from classic accumulator methods.

ARP test mode. According to the idea we design the arithmetic for the key part, first the system sends a message to the target machine, and then system wait for the response. Once system receives a message, it starts to analyze the message, according to the message s parameter system judges whether the message satisfies the conditions. Once the message satisfies all the conditions, the system thinks the machine is sniffing, and adds this machine into the list of sniffing machines. On this basis the detection has done well, and at the same time we insert the result into the log database for inquire and analyze later.
