this paper presents a full duplex, real time implementation of itu-t g.723.1 [7,8] speech coder using the tms320c5402 dsp chip which is based on a 16 bit fixed-point architecture. an optimization method is proposed in order to reduce the total necessary cycle time consumed in real-time implementation. the multi-pulse maximum likelihood quantization (mp-mlq) excitation search block which is the ...

Due to the development of science and technology, the computer has become a useful tool for supporting engineering activities in product design. Many computer aided tools such as CAD/CAM, product data management (PDM), product life cycle assessment (PLA), etc., have been popularly used in industry for reducing product development lead-time and increasing total product quality. However, the nume...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

response surface methodology (rsm) is a statistical method useful in the modeling and analysis of problems in which the response variable receives the influence of several independent variables, in order to determine which are the conditions under which should operate these variables to optimize a corrugated box production process. the purpose of this research is to create response surface mode...

objective(s): t-cell acute lymphoblastic leukemia (t-all) is an aggressive hematologic malignant tumor. administration of chemical compounds influencing apoptosis and t cell development has been discussed as promising novel therapeutic strategies. valproic acid (vpa) as a recently emerged anti-neoplastic histone deacetylase (hdac) inhibitor and pioglitazone (pgz) as a high-affinity peroxisome p...

reliability of a system is the probability that it will function as intended for the required period of time. the opposite of reliability is failure probability per unit time or over time, such as a life cycle. following a review of existing reliability codes and approaches, comprehensive approaches to assess the reliability of offshore structures are described, including probabilistic analysis...
