the physicochemical properties of solute in solutions provide valuable information on solute –solvent, solute – solute and solvent – solvent interactions. the intermolecular forces between theliquids molecules and solvent molecules affect the viscosity of the solution. information regardinginter and intra molecular interactions can be obtained from volumetric, and viscometric data in asolute so...

This paper presents a control design with integral action for vehicle platoons disturbances that ensures string stability of the closed-loop system and disturbance rejection. The addition coordinate change allows development sufficient smoothness conditions on to ensure using proposed controller is stable when subject time-varying disturbances, while rejecting constant disturbances. In addition...

to explain the strategic plan to achieve a new islamic civilization in its various fields and dimensions, a general and scientific structure must be exploited which in accordance with facts of existence from the universe and of human being. this research believes that this general structure along with its entire steps, resources and the foundations of every single one of those steps has been di...

ahmed mahmud is one of the most prominent iranian writers in recent decades. he began his work with writing the short story entitled “sob mishe” and continued with” mool”. he received a position among top rank writers with writing the novel  hamsayeha. many critics have criticized  and studied his works and often dealt with the content of his stories. the paper first addresses form and structur...

Torque ripple minimization of switched reluctance motor drives is a major subject based on these drives’ extensive use in the industry. In this paper, by using a well-known cascaded torque control structure and taking the machine physical structure characteristics into account, the proposed energy-based (passivity-based) adaptive sliding algorithm derived from the view point of energy dissipati...

A square splittered and unsplittered rod is placed in a turbulent boundary layer developed over a flat plate. The effect of the resulting disturbances on the local heat transfer coefficient is then studied. In both cases the square rod modifies the flow structure inside the boundary layer. As a result, a stagnation point, a jet and wake area are generated around the square rod, each making a co...

Disturbance modeling and design of state estimators for offset-free Model Predictive Control (MPC) with linear state-space process models is considered in the paper for deterministic constant-type external and internal disturbances (modeling errors). The application and importance of constant state disturbance prediction in the state-space MPC controller design is presented. In the case with a ...
