Bath A direct conversion modulator-demodulator with even harmonic mixers with emphasis on noise analysis is presented.The circuits consist of even harmonic mixers (EHMs) realized with antiparallel diode pairs (APDPs).We evaluate the different levels of I/Q imbalances and DC offsets and use signal space concepts to analyze the bit error rate (BER) o
Background and ObjectiveVoice disorders are pathological conditions that directly affect voice production.Computer based diagnosis may play a major role in the early detection and in tracking and even development of efficient pathological speech diagnosis, based on a computerized acoustic evaluation.The health of the Voice is assessed by several ac
According to the Alawite teachings in Nahj-ul-Balaghah, the methods of leadership contain two components: "maximum flexibility" and "minimum intensity" (Nahj-ul-Balaghah, letter 46).This leadership style is similar to behavioral theories in management because Bath in the neoclassical school, employees stand at the focus of attention and managers at
In this paper, a structure composed of a T- Cot or L-shaped recycled concrete column frame (RCCF) and lightweight infill wall (LIW) with a herringbone brace has been proposed to investigate its seismic behavior.Two T-shaped and two L-shaped full-size experimental models of the structure have been built and tested under low-cyclic loading conditions
Background: Autogenous costal cartilage is a good option for large volume requirements in rhinoplasty, when septal or conchal cartilages do not suffice.Reluctance to use costal cartilage is due to apprehension of warping.However, warping can be avoided if we follow the principle of balanced section as advocated by Gibson and Davis."Warping" can als
