We have used Terahertz time-domain spectroscopy (THz-TDS) to investigate the complex dielectric function of water solutions containing different ions. Using HCl and NaCl solutions with different concentrations we study the changes of the dielectric response introduced by the ions. We find a linear increase of the real and imaginary part of the dielectric function compared with pure water with i...
We consider a model for quasar formation in which massive black holes are formed and fuelled largely by the accretion of hot gas during the process of galaxy formation. In standard hierarchical collapse models, objects about the size of normal galaxies and larger form a dense hot atmosphere when they collapse. We show that if such an atmosphere forms a nearly ‘maximal’ cooling flow, then a cent...
In this proposed system, the hand gestures are segmented from their backgrounds using a new algorithm to increase the accuracy of the response of gestures. In this, the gesture recognition is m based on the contour model. Hand gesture recognition plays vital role in humancomputer interaction (HCI), because of its extensive applications in Real-Time, sign language recognition, and 3-D games. In ...
Failure prediction methods are becoming sine qua non conditions for effective availability enhancement in complex computer and communication systems. Therefore, there is a growing need for validation, benchmarking and assessment of such methods on real industrial data. Our thesis is that the effectiveness of such methods can be significantly enhanced when combined with fault injection. Then, no...
Ensuring that a distributed real-time system with strict dependability constraints meets its prescribed speciication is a growing challenge that confronts software developers and system engineers. This paper reports on a software fault injection tool, called SockPFI, for testing the fault tolerance and timing behavior of distributed real-time applications. SockPFI, developed on Real-Time Mach, ...
We present a feasibility study to protect smart card software against fault-injection attacks by means of binary code rewriting. We implemented a range of protection techniques in a link-time rewriter and evaluate and discuss the obtained coverage, the associated overhead and engineering effort, as well as its practical usability.
In this study, IP administration of acetaminophen and its half-life were investigated. Acetaminophen as an analgesic drug ordinarily is used in tablets or syrup form. Therefore, there is no report about administration of acetaminophen through injection. Acetaminophen in ED50 dose (200 mg/kg) was injected into the animals intraperitoneally, and its analgesic effect was investigated by formalin t...
We propose a two-phase methodology for quantifying the performability (performance and availability) of cluster-based Internet services. In the first phase, evaluators use a fault-injection infrastructure to measure the impact of faults on the server’s performance. In the second phase, evaluators use an analytical model to combine an expected fault load with measurements from the first phase to...
In this study, we aimed to investigate reproductive performance in estrus-induced Zandi ewes treated with equine chorionic gonadotrophin (eCG) injection in combination with prostaglandin F2α (PGF2α)and gonadotrophin releasing hormone (GnRH) during non-breeding season. The estrous cycle was synchronized using controlled internal drug release (CIDR) for 12 days. The ewes were randomly assigned to...
The phenomenon of sleep is an active nervous and biologic rhythm, which is under influence of neurotransmitters of central nervous system. In this study, the influence of serotonergic system on sleeping time have been assessed by agonist-antagonist drugs using two methods of induction and non-induction behavioral and electrophysiology. The method used for measurement of total sleeing time was A...
