abstract: in this study, it has been tried to test the accuracy of output and hence the model efficiency in the predictions of 24 and 48 hour precipitation forecasting by choosing different schemes be assessed. therefore, in order to test the accuracy of model product, two conditions of rainfall precipitation and lack of rainfall precipitation were considered. four thresholds were taken. adapti...

considerable indirect taxes are obtained to finance different expenditures of governments. the indirect taxes have different and to somewhat contrary effects in the economy. this paper investigates on the effects of the indirect taxes on sectors’ products to finance the government expenditures. using an input-output analysis, the effects of this policy on the cost-push price inflation and emplo...

energy is one of major factors of productions in all of economic sectors, which have important effect on a country economy. the effect of increasing price of energy carriers on productions of economic sectors is inevitable. therefore, this research was conducted by using the input - output model and product forecasting. the study investigated the latest available input - output table in 1385. t...

ActiveCube is a novel device that allows a user to construct and interact with a 3D environment by using cubes with a bi-directional user interface. A computer recognizes the 3D structure of connected cubes in real time by utilizing the real-time communication network among cubes. Also, ActiveCube is equipped with both input and output devices, at where the user expects to be, and this makes th...

technological developments in various sectors and considering the speed and accuracy as an integral part of the decision-making process in the age of knowledge economy, has caused the disaster economy an important role in risk assessment and management in national and regional planning. the development of models used in this area, resulted in considering indirect consequences of disasters on th...

Given a parallel or distributed system, the interconnection network ensures the communication between the processors, the terminal nodes. Each intermediate node has a router, a dedicated co-processor which forwards the messages between processors through the links of the underlying topology. The routers run a distributed algorithm which specifies the way to go from a node of the network to anot...

kashan aquifer is adjacent to salt lake. because of this adjacency, the saline water of the lake has moved to the aquifer. in this study groundwater quality of the aquifer was simulated using artificial neural network (ann) model. for this purpose, the dominant ion of water was first determined by piper diagram. results showed that the sodium chloride is the dominant ion of water and so it was ...

It is well-known that part of speech depends on context. The word ‘‘table,’’ for example, can be a verb in some contexts (e.g., ‘‘He will table the motion’’) and a noun in others (e.g., ‘‘The table is ready’’). A program has been written which tags each word in an input sentence with the most likely part of speech. The program produces the following output for the two ‘‘table’’ sentences just m...
