implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
Numerous approaches to verifying the safety of vehicles in the AHS architecture of PATH have been proposed (see 1] and 2]). One approach involves nding a boundary between safe and unsafe initial conditions. This task is signiicantly easier if we can guarantee that the severity of an accident is monotonic in the initial conditions. Simulation results are presented in which it is shown that this ...
in the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. according to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. on the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. in the primary stage of th...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
Optimal control systems are of considerable practical and theoretical interest. Although solutions of certain optimal control problems have been known for many years, it is only recently that fairly general, rigorous solution techniques have been developed. Unfortunately, the computational aspects of these solution techniques still present formidable problems. The time-optimal problem which is ...
this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....
The need for reliability and robustness in present day systems requires that they possess the capability for accommodating faults in the controlled plant. Fault accommodation requires tight integration of online fault detection, isolation, and identi cation with the system control loop. This paper develops an e ective fault diagnosis scheme for plants that mainly exhibit continuous behavior, bu...
This paper deals with the automated veriication of a class of task-control systems with periods, durations, and scheduling specii-cations. Such systems are translated into Periodic Hybrid Automata for veriication. We show that safety, liveness, and time-bounded properties are decidable for the considered systems.
