A Stream Input-Output System
نویسنده
چکیده
In a new version of the Unix operating system, a flexible coroutine-based design replaces the traditional rigid connection between processes and terminals or networks. Processing modules may be inserted dynamically into the stream that connects a user’s program to a device. Programs may also connect directly to programs, providing interprocess communication.

A Stream Cipher Based on Chaotic Permutations
In this paper we introduce a word-based stream cipher consisting of a chaotic part operating as a chaotic permutation and a linear part, both of which designed on a finite field. We will show that this system can operate in both synchronized and self-synchronized modes. More specifically, we show that in the self-synchronized mode the stream cipher has a receiver operating as an unknown input o...
متن کاملApplication of “Sink & Source” and “Stream wise” Methods for Exergy Analysis of Two MED Desalination Systems
Utilization of fossil fuel for supplying of requires energy of desalination systems is common. On the other hand, solar energy is one of the high-grade energies in the world that can be found specifically in hot weather places. Therefore, utilization of solar energy for operation of desalination systems will reduce greenhouse gases and is a good alternative way. Common exergy analysis method (s...
متن کاملInterfaces for Stream Processing Systems
Efficient processing of input data streams is central to IoT systems, and the goal of this paper is to develop a logical foundation for specifying the computation of such stream processing. In the proposed model, both the input and output of a stream processing system consists of tagged data items with a dependency relation over tags that captures the logical ordering constraints over data item...
متن کاملIdentification of Multiple Input-multiple Output Non-linear System Cement Rotary Kiln using Stochastic Gradient-based Rough-neural Network
Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...
متن کاملA PVS Implementation of Stream Calculus for Signal Flow Graphs?
We present early work on a PVS implementation of a model of simple control as signal flow graphs to enable formal verification of input/output behaviour of the control system. As has been shown by Rutten, Signal flow graphs can be described using Escardó’s coinductive stream calculus, which includes a definition of differentiation for streams over the real numbers and the use of differential eq...

The main problem of vehicle vibration comes from road roughness. An active suspension systempossesses the ability to reduce acceleration of sprung mass continuously as well as to minimizesuspension deflection, which results in improvement of tire grip with the road surface. Thus, braketraction control and vehicle maneuverability can be improved consider ably .This study developeda new active su...
