در این رساله عملکرد یک موتور توربوپراپ که ملخ آن از نوع clark y 5868-r9 است در شرایط نقطه طرح (on- design) و خارج از نقطه طرح (off- design) مورد مطالعه قرار گرفته شده است. موتور توربوپراپ یکی از انواع موتور جت در تراست بالا و مصرف مخصوص سوخت پایین است که عدد ماخ پروازی آن هرگز از 8/. تجاوز نمی کند. دور موتور های توربوجت به حدی زیاداست که در صورت اتصال مستقیم به ملخ، سرعت نوک تیغه های ملخ به سرع...

Due to the increasing tendency construct taller and more slender buildings, need address aerodynamic induced dynamic forces (inertial forces) under both service strength-level wind loads has become important. Currently, application of performance-based design (PBWD) reduce applied through acceptance inelastic deformation is permitted as an alternative approach, in which load can be reduced with...

The degree to which hardware and operating systems support debugging strongly in uences the caliber of service that a debugger can provide. We survey the di erent forms in which such support is available. We limit our survey to lower-level debugger design issues such as accessing the debugged program's state and controlling its execution. The study concentrates on those types of support that ma...

First order reliability method (FORM) for the computation of reliability index has been used widely because of its advantages of the efficiency and effectiveness as well simplicity for many years. There exists the phenomenon of convergent failure in the FORM in calculating the reliability index iteratively for some limit state functions, for which the essential factor is investigated using chao...

Conducted analyse of the knowledge of design brick arched lintels shows lack of information about the mentioned process. The only piece of information, reached by the author, includes simplified matching method of arch’s shape by empirical use of ultimate limit state method. Presented paper contains review of more interesting empirical and numeric research. Additionally, the analyse of technica...

The Extensible Authentication Protocol (EAP) allows a server to request authentication information from a client. In order to transport EAP messages over an IP network, the Protocol for Carrying Authentication for Network Access (PANA) has been developed. This paper applies a protocol engineering methodology using Coloured Petri nets (CPNs) as a step towards formally verifying the design of PAN...

the aim of this study was the increasing of leachate quality using integrated membrane bioreactor (mbr). the reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the analysis of cod, biochemical oxygen demand (bod5), total suspended solids (tss), and total dissolved solids (tds) were performed in feed and filtrate, whenever the system reached steady stat...

In recent years, reliability-based design (RBD) has gradually gained popularity in geotechnical engineering. Several RBD codes have been developed and implemented around the world that calibrate ultimate limit state (ULS) designs for a target ULS reliability index (βuls). However, the serviceability limit state (SLS) design still is considered using conventional deterministic approaches with an...

In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
