Ch. 23 Cointegration 1 Introduction An important property of (1) variables is that there can be linear combinations of theses variables that are I(O). If this is so then these variables are said to be cointegrated. Suppose that we consider two variables Yt and Xt that are I(1) (For example, Yt= Yt-1+ St and Xt= Xi-1+nt.)Then, Yt and Xt are said to be cointegrated if there exists a B such

Cyclic Codes a cyclic code is a linear block code where if c is a codeword, so are all cyclic shifts of c E.g., 1000, 110, 101,011 is a cyclic code Cyclic codes can be dealt with in the very same way as all other lbc s Generator and parity check matrix can be found a cyclic code can be completely described by a generator string G All codewords are multiples of the generator string In practice, cyclic codes are often used for error detection(CRc) Used for packet networks When an error is detected by the received, it requests retransmission

n this chapter First: to find relations between properties that might not be thought to be related to derive expressions for the variation of the g with Tand p Second: to introduce the chemical potential, a property that will be at the center of discussions in the remaining chapters of this part of the text; to derive expression of fugacity

Let be the set of all input variables, X={, X1, .Xn} Let y be the set of all output variables, y={Y, 1 ...m} o The combinational function, F, operated on the input variable set, to produce the output variable set y. o The output is related to the input as

Directions: In this section, you will hear ten short conversations. At the end of each conversation, a question will be asked about what was said. Both the there will be a pause. During the pause, you must read the four choices marked A),),C) and D),and decide which is the best answer. Then mark the corresponding letter on the Answer Sheet with a single line through the center

As aerosols are important sources of infection, care should be taken to reduce the extent of their formation and dispersion Hazardous aerosols can be generated by many laboratory operations, e.g. blending, mixing, grinding, shaking, stirring, sonicating and centrifuging of infectious materials. Even when safe equipment is used, it is best to carry out these operations in an approved biological safety cabinet whenever possible

Chapter 6. Laboratory animal facilities Those who use animals for experimental and diagnostic purposes have a moral obligation to take every care to avoid causing them unnecessary pain or suffering. The animals must be provided with comfortable, hygienic housing and adequate wholesome food and water At the end of the experiment they must be dealt with in a humane manner
