a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...

A PLTU must carry out operational tasks continuously to meet electricity needs. Based on historical data PT. PJB Service Kendari for the last three years, there has been an increasing trend of downtime and derating at Nii Tanasa Kendari. The boiler system is one systems that often experiences disturbances. purpose this research a risk analysis improve reliability using FMECA method calculations...

Interactions measured on the additive scale are more relevant than multiplicative interaction for assessing public health importance and also more closely related to notions of mechanistic synergism. Most work on sample size and power calculations for interaction have focused on the multiplicative scale. Here we derive analytic expressions for sample size and power calculations for interactions...

Overtopping is one of the main factors responsible for dam failure. To avoid overtopping, dam is equipped with one or some spillways to release the water impounded in the reservoir. The number and size of these spillways are determined on the basis of design flood. Determination of design flood of dam spillway can be formulated as a multiobjective risk problem. This problem can be solved by Qua...

Competition is the driving force of today's economy and it is vital for organizations to gain competitive advantages. In recent years, outsourcing has been the focus of managers as a tool for developing organizations and improving productivity. This study deals to analyze the outsourcing risks of the supply chain in the automotive industry using fuzzy inference systems. For this purpose, in the...

The binding energy and geometrical structure of all the possible dimeric systems of isothiocyanic acid (HNCS) with ozone have been investigated in the gas phase, theoretically. Six minima located on the singlet potential energy surface of the HNCS–ozone system at the MP2 level with binding energies (corrected with ZPE and BSSE) in the range 492.29–531.40 kcal/mol. All intermolecular interaction...
