to Probability Models‚ Academic Press‚ and J. Hamilton‚ Time Series Analysis‚ Princeton University Press. Definition 1 A stochastic process {X (t )‚ t ∈ T } is a collection of random variables: for each t ∈ T ‚ X (t ) is a random variable. The set T is called an index set‚ and t ∈ T is often interpreted as time. So X (t ) would be the (random) state of a process at time t . Sometimes for simplicity we write X t = X (t ). Note that each X t is a random variable‚ so really we should be writing

Communication Process Communication is the process of sending and receiving messages with attached meaning ( Schermerhorn‚ Osborn‚ Hunt 2000). Communication process has the following basic aspects‚ which are source‚ receiver‚ channel‚ noise and feedback. The source is the person that encodes a message in understandable terms‚ and then transmits it via a communication channel that carries the message. There are various communication channels such as face-to-face meetings‚ emails‚ memorandums‚ faxes

An example of a business process: Credit card approval in a bank. An applicant submits an application. The application is reviewed first to make sure that the form has been completed properly. If not‚ it is returned for completion. The complete form goes through a verification of information. This is done by ordering a report from a credit company and calling references. Once the information is verified‚ an evaluation is done. Then‚ a decision (yes or no) is made. If the decision is negative

A Process Paragraph A process is a series‚ a sequence‚ an orderly progression. One step or event follows another: first this‚ then that‚ then something else. You generally write a process paragraph to accomplish one of two tasks: 1. To describe how to make or do something (directional process) 2. To describe how something works (informational process) The Structure of a Process Paragraph 1. The topic sentence names the process and indicates the reason someone should be interested in knowing about

A process costing system is a costing system in which the cost of a product or service is obtained by assigning costs to masses of like or similar units. Unit costs are then calculated on an average basis. Process costing systems are used in industries that produce like or similar units which are often mass produced. In these industries‚ products are manufactured in a very similar way. The companies usually use the same amount of direct materials‚ direct manufacturing labor costs and manufacturing

The Scientific Process is commonly represented as a linear process‚ but is better represented by a web or cyclic process because there is no distinct beginning or end. The cyclic process shows that there is no pattern to the process of science‚ and that one discovery can lead to a whole new process. Scientists can’t precisely predict exactly where their research might take them. The linear process shown in textbooks does not accurately portray the Scientific Method. It only shows one distinct path

The Refrigeration Process Refrigeration has probably been around longer than you think. In 1823‚ Michael Faraday discovered that certain gases under constant pressure will condense when they cool. In 1875‚ Raoul Picet used sulfur dioxide as a refrigerant and in 1931 Refrigerant R-12 was developed by Thomas Midgley and C. F. Kettering. The Kelvinator refrigeration unit‚ ice cream units‚ and Semi-hermetic compressors were introduced at the beginning of the 20th century. In this
