This study demonstrates the applicability of pressurized stirred tank bioreactors for oxygen transfer enhancement in aerobic cultivation processes. The specific power input and the reactor pressure was employed as process variable. As model organism Escherichia coli, Arxula adeninivorans, Saccharomyces cerevisiae and Corynebacterium glutamicum were cultivated to high cell densities. By applying...

Power transformer rupture and fire resulting from an arcing fault inside the tank usually leads to significant security risks and serious economic loss. In order to reveal the essence of tank deformation or explosion, this paper presents a 3-D numerical computational tool to simulate the structural dynamic behavior due to overpressure inside transformer tank. To illustrate the effectiveness of ...

Demand for faster data rates in wireline and wireless markets has resulted in tighter jitter and phase noise requirements for oscillators. Although active device noise (and not the resonator noise) dominates the phase noise of most CMOS oscillators [1], in a properly designed oscillator, the quality factor, Q, of the resonant tank indirectly plays a central role in the phase noise. The best pha...

In order to improve the efficiency of sewage treatment, we construct P-ILC algorithm for output data dropouts. The P-ILC algorithm is used in the aeration tank of oxygen input link, and according to the actual situation, considering the data generating omissions, adjusting the algorithm can completely control the aeration tank of oxygen. After 15 iterations, we can completely control the oxygen...

We propose an efficient solution to optimize buffer dumping allowing to reduce significantly the losses caused by buffer overflow. To highlight the proposed architecture we have analyzed its performance compared with different configurations of polling scheme.

Whale Tank Virtual Reality is a novel technique for collocated collaboration in virtual reality. It provides a simple solution for head-coupled virtual reality technology allowing more than one user at a time to observe a 3D scene from a correct perspective. Whale Tank VR employs natural interaction using a large touch screen display. It provides each user with a personal viewport into the virt...

Fish tank VR systems provide head coupled perspective projected stereo images on a display device of limited dimensions that resides at a fixed location. Therefore, fish tank VR systems provide only a limited virtual workspace. As a result, such systems are less suited for displaying virtual worlds that extend beyond the available workspace and depth perception problems arise when objects that ...
