Starting at the ground, conditions have to be very calm winds less than 2 mph, with no 28 precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence. The supersonic descent could happen as early as Sunda. The weatheThe balloon will slowly drift to the edge of space at 120,000 feet ( Then, I would assume, he will slowly step out onto something resembling an Olympic diving platform. Below, the Earth bees the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, he39。t start planning...

However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it. If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。 U1:SOUT PORT MAP(CLK=L_CLK,ENABLE=T_ENABLE,CLR=T_CLR,STO=T_STO,ST=L_ST)。 END COMPONENT。 C3:OUT STD_LOGIC_VECTOR(3 DOWNTO 0))。 COMPONENT PULSE PORT(CLK0:IN STD_LOGIC。 CLK_OUT:OUT STD_LOGIC)。 T_CLR:IN STD_LOGIC。 // 程序作者 ： 金人佼 // 最后修改日期 ： LIBRARY IEEE。 //顯示數(shù)字 6 WHEN 0111=SG=0000111。 END PROCESS P2。 WHEN 01=BT=010。 THEN IF SQ=10 THEN SQ:=00。 BT:OUT STD_LOGIC_VECTOR(2 DOWNTO 0))。 // 程序作者 ： 金人佼 // 最后修改日期 ： LIBRARY IEEE。 END IF。 ELSE IF Q21001 THEN Q2:=Q2+2。 WHEN 11= IF Q10101 THEN Q1:=Q1+5。Q2:=0000。Q3:=0000。 END COUNTER。 USE 。 //FULL 賦低電平 END IF。EVENT AND CLK0=39。 USE 。 //CQI80 時， state 賦 11 態(tài) END IF。 THEN STATE:=00。 THEN CQI:=(OTHERS=39。 STO :IN STD_LOGIC。 END PROCESS。 //快速檔的時鐘信號 JS:IN STD_LOGIC。在這次課程設(shè)計中也使我們的同學(xué)關(guān)系更進一步了，同學(xué)之間互相幫助，有什么不懂的大家在一起商量，聽聽不同的看法對我們更好的理解知識，所以在這里非常感謝幫助我的同學(xué)。各模塊完成后，在將它們組合成完整的出租車系統(tǒng)，在設(shè)計過程中還需要改進的是控制系統(tǒng)的糾錯功能。 程序輸入完成后進行編譯， 編譯完成后，可以對所進行的設(shè)計進行仿真，本課程設(shè)計的 9 仿真平臺是 MAX+plusⅡ ,通過對 VHDL 源程序進行編譯檢錯，然后創(chuàng)建波形文件（后綴名為 .scf），加入輸入輸出變量，選擇適用的芯片以及設(shè)定仿真結(jié)束時間，設(shè)置好輸入初值進行仿真，得到仿真波形圖： MS 的結(jié)果驗證 (如圖 ) 圖 當(dāng) JS 為高電平， CLK_OUT 按照 CLK1 輸出；低電平時，按照 CLK0 輸出 2 模塊 SOUT 的結(jié)果驗證 (如圖 ) enable 高電平時，每一個時鐘上升沿時， CQI 計數(shù)加 1，若 CQI=30 時， state 賦 01，30CQI=80 時， state 賦 10態(tài)， ? ..； enable 低電平時， CQI 計數(shù)暫停，保持不變 圖 3 模塊 PULSE 的結(jié)果驗證 (如圖 ) 10 每個 CLK0 上升沿時， CNT 計數(shù)加 1，加到 4 時在下一個時鐘上升沿賦值 0； t 不為 0時 fout 賦值高電平，否則低電平 圖 4 模塊 COUNTER 的結(jié)果驗證 (如圖 ) SI 為出租車狀態(tài)信號：“ 00”表示計費值停止， Q1~Q3 不變 。 車速選擇 起 /停 開關(guān) 基本速率 Reset 掃描時鐘 顯示輸出 顯示輸出 車速 控制模塊 計費動態(tài)顯示 里程 動態(tài)顯示 6 4 設(shè)計步驟 VHDL 設(shè)計流程圖 （如圖 ） ： 圖 VHDL 設(shè)計流程圖 圖 系統(tǒng)的總體模塊圖 VHDL 文本編輯 VHDL 文本編輯 FPGA/CPLD 適配器 FPGA/CPLD 編輯下載器 VHDL 仿真器 F
