Peroxisome inheritance at the right time and place E very yeast cell has numerous peroxi-somes—organelles that metabolize fatty acids— and roughly half are passed on to their daughter cells. Signaling from the bud to the mother cell ensures even peroxisome distribution by controlling the organelles' transport, say Fagarasanu et al. Peroxisomes travel into the bud along actin tracks using the my...

Innovation is essential especially in such a highly competitive and fast changing market as we see in the telecommunication industry. Research and development are the groundwork to make innovation possible and also challenge the whole organisation to think ahead. It is a long way from an idea to real products and we will show the process and tools to help companies to choose and prioritise the ...

Electric drives control without shaft sensors has been an active research topic for almost three decades. It consists of estimating the rotor speed and/or position from the currents and voltages measurement. This paper deals with the observability conditions of electric drives in view of sensorless control. The models of such systems are strongly nonlinear. For this reason, a local observabilit...

Solid state drives(SSDs) are increasingly being used for database applications, due to their low seek latency and low power consumption. Solid state drives differ fundamentally in their characteristics from disk drives, which mandates that some core database design decisions, such as column layout, needs to take into account the specific characteristics of SSDs for optimal performance. This pap...

Neural schema mechanism is an embodied autonomous agent control structure that makes use of both neural network and symbolic constructs to learn sensory motor correlations and abstract concepts through its own experience. The mechanism can also learn which intermediate states or goals should be achieved or avoided based on its primitive drives. In addition, a psychological theory of consciousne...

The paper presents the theory of control systems for electrical drives based on fuzzy logic, from the author’s point of view. The paper offers practical answers at questions related to the design of speed control systems based on fuzzy PI speed controller: what is the adequate structure of fuzzy controller, the number of rules fuzzy values, how to assure stability, implementation, control syste...

The IBM Virtual Tape Server provides a revolutionary tape storage solution that emulates tape drives using a disk cache, providing up to 256 virtual tape-drive images and stacking the virtual tape volumes onto a maximum of 12 physical tape drives. The high ratio of virtual to physical drives, combined with the stacking of virtual volumes, provides tape storage that is both costand space-efficie...

Recent work has not only defined the origin of the direct cortico-motoneuronal output to the upper limb but has also identified some of the cortical networks that engage the corticospinal output during movement. A surprising finding is that some corticospinal neurons show 'mirror-like' properties and are actively modulated not only during self-movement but also during action observation.

While promotional literature about computer science programs may claim that curricula are determined by the needs of the students and by international best practice, the reality is often different. In this paper we reflect on the factors underlying curriculum change in computer science departments and schools, from institutional requirements and financial pressures to purely academic considerat...

The accuracy of rotor position estimation in the (several kHz), and its amplitude cannot be changed as it is conventional signal injection based sensorless control of determined by the DC-link voltage and the PWM duty cycle, permanent magnet brushless AC drives depends on the load the amplitude of high frequency current will be too small for current. This paper proposes an improved method, whic...
