免費軟體-好用的網路收音機Tapinradio

以前學英語跟聽熱門音樂靠的是收音機與ICRT廣播電台~
現在軟體設計越來越方便~只要透過網路~便能連結世界各國的音樂電台~

甚至連只對區域開放的電台都能收聽~(想想~為何要限制??)


這套軟體"Tapinradio"

下載點
http://www.raimersoft.com/tapinradio.aspx

按下"Type to search"旁的下拉鍵它就會分出四個大分類~
Countries-國家別
Genres-年代
National-國家別
Networks-網路

可自行按一下~畢竟茫茫"廣播海"

邊尋邊找~才是樂趣~

且在"Stations"中還可勾選"Show station meanu"
便可看到及時播放的曲目

狠棒耶~

在Chrome 上使用 PDF-Xchange

PDF-XChange Viewer
一個非常好用的 PDF閱讀器
許多網站已寫過~所以不多說了~
下載點

但若要在Chrome上使用~請您跟我這樣做~

輸入 chrome://plugins/
停用 Adobe Acrobat
停用 Chrome Acrobat
勾選 PDF-XChange Viewer

順利完成

沒亂花~信用卡也會被盜刷- 請小心

今日收到聯邦的簡訊~ 說我刷卡2*,***...
但我狐疑得很~小弟我已經很久沒如此大方了

所以打到客服中心詢問
核對了一下資料~ 幸好最近生意做不大~交易很單純~
確認應該是非常有問題~

而之後~中心處理查詢資料後~
人員很快回復說是PayPal(國際付費系統)再度跟我確認授權情況
Of Course... NO....

我立刻採行下數步驟
1.查詢交易明細
2.提出申訴
3.更改必要資訊


感言...
1.簡訊空間要清空~這次若不是聯邦早點提醒~這下又得紛擾一陣子~
2.偶爾要查一下簡訊~雖然廣告多~
3.... 交易安全漏洞真是遍布全球~


不過話說~這個傢伙頗為奇怪~或說市利害~
電子郵件：**********@yahoo.com.tw(先不打草驚蛇)

台灣的帳號~計價為英鎊 GBP  收件還是德國漢堡的一間表演工坊...
會是台灣之光到德國嗎???  喔~ 不是光~ 是黑暗~


想想我也太紅了吧~
在家看書還到德國消費現場表演... 真是~


DG
忘了說~
可愛的聯邦客服 很細心 服務也很迅速
只是... PayPal念做"貝寶" 不是"貝配而"

害我聽不懂... 只好確認一次拼法~
但~真的服務很好~

感恩~

流行病學的傳染方程式-Kermack-McKendrick

最近對Diffusion產生了興趣~
結果又回到公共衛生的老本行-其實也不算"老本行"~只是大學四年修過且被當過很多次~
但說真的~印象中還真的沒學到這一塊-以數學模型估算感染的傳遞影響力...
...若公共衛生沒學到... 那... 怎管制疾病...

但是因為紅蔥頭我小時不努力~數學給它半知半解~當然微積分則更...不敢說明~
卻啊~到了四時多才發現數學的妙用-用"簡明的語言"來說明複雜問題的趨勢~...

只好到這時問東問西~甚至借來高中數學慢慢理解~

而以下呢~則是最近頗改興趣的領域~ 特別記錄一下~

以下文章為網路上找到的

The Kermack-McKendrick model is an SIR model for the number of people infected with a contagious illness in a closed population over time. It was proposed to explain the rapid rise and fall in the number of infected patients observed in epidemics such as the plague. It assumes that the population size is fixed (i.e., no births, deaths due to disease, or deaths by natural causes), incubation period of the infectious agent is instantaneous, and duration of infectivity is same as length of the disease. It also assumes a completely homogeneous population with no age, spatial, or social structure. The model consists of a system of three coupled nonlinear ordinary differential equations, (1) (2) (3) where is time, is the number of susceptible people(易受感染), is the number of people infected(被感染病人數), is the number of people who have recovered and developed immunity to the infection(產生免疫力的人), is the infection rate(感染的機率), and is the recovery rate(復原的機率).The key value governing the time evolution of these equations is the so-called epidemiological threshold, (資料2稱為基本再生率) (4) Note that the choice of the notation is a bit unfortunate, since it has nothing to do with . is defined as the number of secondary infections caused by a single primary infection(研究的限制); in other words, it determines the number of people infected by contact with a single infected person before his death or recovery(端視傳染力強不強). When , each person who contracts the disease will infect fewer than one person before dying or recovering(疾病到控制), so the outbreak(爆發) will peter out (). When , each person who gets the disease will infect more than one person(不只傳染一位~所以不易控制), so the epidemic will spread (). is probably the single most important quantity in epidemiology. Note that the result derived above, applies only to the basic Kermack-McKendrick model, with alternative SIR models having different formulas for and hence for . The Kermack-McKendrick model was brought back to prominence after decades of neglect by Anderson and May (1979). More complicated versions of the Kermack-McKendrick model that better reflect the actual biology of a given disease are often used. 參考資料 1.大部份資料來自(Most sentence was taken from- http://mathworld.wolfram.com/Kermack-McKendrickModel.html If copyright infringement, please sent me an e-mail.  I will take this article off as soon as possible. 2.http://dufu.math.ncu.edu.tw/calculus/calculus_eng/node137.html DG **If copyright infringement, plase let me know.  I will take this article off as soon as possible.**
