Abstract—The power buck converter is the most widely used DC/DC converter topology. They have a very large application area such as DC motor drives, photovoltaic power system which require fast transient responses and high efficiency over a wide range of load current. This work proposes, the modelling of DC/DC power buck converter using state-space averaging method and the current-mode control ...

− This article presents further testing and verification results for a previously introduced new intelligent regulation method that controls the power-electronic Buck converter utilizing a small-signal model of the pulse width modulation (PWM) switch. The implemented intelligent control method uses a fuzzy-PID controller that is tuned using the global search method of genetic algorithm (GA). Th...

Aims: To determine the alterations in some haematological and serum biochemical parameters contagious ecthyma (CE) or Orf-infected Sokoto red goats (SRG).
 Presentation of Case: Following a complaint sore mouth disease SRG, patients were noticed to be docile, pyrexic with congested visible mucus membranes. There crusty skin lesions around oral nasal commissures which firm painful. Blood sa...

In this work a buck converter model for multidomain simulations is proposed and compared with a stateof-the-art buck converter model. In the proposed model no switching events are calculated. By avoiding the computation of the switching events in power electronic models the processing time of multi-domain simulations can be decreased significantly. The proposed model calculates any operation po...

Most mobile equipments use battery as power source. The increasing use of low voltage portable devices and growing requirements of functionalities embedded into such devices. Thus an efficient power management technique is needed for longer battery life for them. Given the highly variable nature of batteries systems often require supply voltages to be both higher and lower than the battery. Thi...

The changes in genital tract morphometry, foetal dimensions, the relative volumes of fluids during gestation was evaluated Red Sokoto (Maradi) does using 28 gravid genitalia. Based on ages fetuses, each genitalia classified into one three phases namely: early, mid and late for a comparison all parameters. While both uterus placenta were significantly enlarged, (P<0.05) at gestation, other mo...
