Modern automobiles are complex distributed systems in which virtually all functionality — from acceleration and braking to lighting and HVAC — is mediated by computerized controllers. The interconnected nature of these systems raises obvious security concerns and prior work has demonstrated that a vulnerability in any single component may provide the means to compromise the system as a whole. T...

This paper presents a second-law of thermodynamics analysis to quantify the exergy destruction in each component of an Environmental Control Unit (ECU) for military applications. The analysis is also used to identify the potential contribution from each component to improve the overall energy efficiency of the system. Three ECUs were investigated experimentally at high ambient temperature condi...

Wireless sensor networks are an efficient way of reading and transmitting information through a system of controls. They are used for a variety of purposes. The signals passed between each sensing unit and the central control unit needs to be theoretically nonexistent for perfect transmission but there are many hindrances like transmission techniques and physical disturbances which cause delay....

The aim of this paper is the steady state and dynamic simulations of the ammonia unit of Shiraz petrochemical complex and system behavior study versus the feed flow rate change for producing a good quality product. The ammonia unit consists of the reformer units, shift converter units, carbon dioxide absorption unit, methanation unit, and ammonia synthesis unit. For this purpose, in the first s...

We describe an approach for doubling distribution grid capacity for connecting renewable generators based on curtailing a maximum of 5 % of the yearly energy fed in to the grid on a pergenerator basis. The paper contains information about the control unit needed for automatic minimum curtailment and the field test that has been set up to validate the approach. Furthermore, topics concerning the...

Active vibration control has been introduced and used as one of the effective approaches to suppress unwanted vibrations in different systems. Effective performance of each vibration control method is contingent to accurate design and proper dynamics selection of the control unit. These methods have been extensively studied in various studies in recent years. Each of these new methods are desig...
