TL;DR: Thank you very much for reading input output analysis foundations and extensions, as many people have search hundreds of times for their chosen readings like this, but end up in infectious downloads.
Abstract: Thank you very much for reading input output analysis foundations and extensions. As you may know, people have search hundreds times for their chosen readings like this input output analysis foundations and extensions, but end up in infectious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they are facing with some malicious virus inside their desktop computer.

TL;DR: Input-output analysis is a method of calculating income and employment multipliers which takes account of differences in technology between industries and of the linkages between industries.
Abstract: Input-output analysis is a method of calculating income and employment multipliers which takes account of differences in technology between industries and of the linkages between industries. The data required is the input-output accounts for the region often referred to as the transactions matrix. Example: the numbers are billions of $ Purchases Sales interm, demand final demand sector manuf. nonmanuf cons. govt. expt. total inter. manuf, 18 18 40 14 30 120 inputs nonman 20 37 43 7 18 125 hshlds 56 52 16 9 27 160 prim. govt. 6 7 20 22 0 55 inputs impt. 20 11 41 3 5 80 total 120 125 160 55 80 Here just two industrial sectors are used. Their output and the income and employment generated in each sector is determined by the final demand for the output of each sector. Input-output analysis is a method for estimating how changes in final demand will affect these outputs, incomes and employment.

TL;DR: This survey provides an overview of the general SCADA architecture, along with a detailed description of the SCADA communication protocols, and carries out an extensive review of the security proposals and tactics that aim to secure SCADA systems.
Abstract: Supervisory Control and Data Acquisition (SCADA) systems are the underlying monitoring and control components of critical infrastructures, such as power, telecommunication, transportation, pipelines, chemicals and manufacturing plants. Legacy SCADA systems operated on isolated networks, that made them less exposed to Internet threats. However, the increasing connection of SCADA systems to the Internet, as well as corporate networks, introduces severe security issues. Security considerations for SCADA systems are gaining higher attention, as the number of security incidents against these critical infrastructures is increasing. In this survey, we provide an overview of the general SCADA architecture, along with a detailed description of the SCADA communication protocols. Additionally, we discuss certain high-impact security incidents, objectives, and threats. Furthermore, we carry out an extensive review of the security proposals and tactics that aim to secure SCADA systems. We also discuss the state of SCADA system security. Finally, we present the current research trends and future advancements of SCADA security.
