Path planning based on artificial potential field method, particle swarm optimization algorithm and fuzzy logic controller for navigation in static and dynamic environments. Two schemes of motion controller are used. The first scheme is based on PID controller and second scheme is based on fuzzy logic controller. The PID controller parameters and parameters of membership functions have been optimized by using particle swarm optimization (PSO) algorithm.

Inulinase is an enzyme catalyzing the hydrolysis of inulin, a plant reserve polysaccharide, into fructoses and fructo-oligosaccharides which are widely used in pharmaceutical and food industry. Although several substrates for the production of inulinase have been reported as being economically effective such as utilization of inulin-rich substrate rather than pure inulin, however, there is still need to develop the substrate to make the entire process much cheaper and more effective. Here we reported inulinase production from Acinetobacter as there is not found any report on inulinase...

Microbiological investigation of male partners in infertile couple can be useful to detect the male urogenital tract infection, especially asympto-matic infections. The isolation of microorganisms from seminal fluid especially of infertile men had been widely reported.It is always recommended that microbiological study of semen can be performed in asymptomatic infertile men with leukocytospermia. Aerobic and anaerobic culture of semen can detect a wide range of urogenital pathogens. Little or no attention has been paid to the role of bacterial infection of seminal fluid in asthenospermia and...

Microlens arrays contain multiple lenses formed in a one-dimensional or two-dimensional array on a supporting substrate. With optical sensor arrays tiny lens systems serve to focus and concentrate the light onto the photodiode surface instead of allowing it to fall on non-photosensitive areas of the pixel device. Fill-factor area occupied by the microlens arrays. Mostly, the lens shape is cylindrical or spherical. Array size strongly depends on the applications. It can range from 1x2 for optical switch applications up to more than 103x103 for diffusers or display applications. Single...

Porous alumina forms on the surface of aluminum in a self organized manner when anodized in an acid under specific conditions. Such templates have recently emerged as an important self-assembly method for nanofabrication.They can be used in different ways to synthesize self-assembled arrays of nanowires and nanodots of a variety of materials, such as metals, alloys, binary compounds, and multilayers. Characterization of these materials can easily be achieved by releasing the nanowires from the template. Magnetic, electric, transport, and optical measurements all contribute toward the...
