in order to evaluate the interference effect natural population weeds and plant density, an experiment with randomized complete block design in factorial arrangement with 4 replications was conducted in 2006 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments included two factor, plant density of corn at three levels (4, 7 and 10 plants m-2) and ...

contextual interference is one of the instructional methods for several skills.the aim of this research was to determine the effects of interference beforeperformance and interference during performance on the acquisition and retentionof generalized motor program and parameter in basketball skills with an emphasison the examination of contextual interference hypotheses and self-regulationlearni...

This contribution presents a fixed point implementation for acoustical active noise control in hearing defenders. The well known filtered-x least mean squares structure is conformed to fixed point arithmetic and evaluated in real time. The measured performance of the implementation is 20dB to 30dB attenuation of broad band noise and ca 60dB for sinusoidal interference. The implementation uses a...

The embedded-systems industry is about to make a transition to multi-core platforms. This is a highly risky step as several essential problems are not yet solved. In particular, the performance analysis problem has no viable solution for the existing multi-core designs. The main culprit is the interference on shared resources. Several alternative approaches both in architecture and system desig...

Researchers from academia and industry will present the latest developments in the application of interference RNA (RNAi) as a tool for gene silencing at “RNAi2008 Functions and Applications of Non-coding RNAs” to be held in March in Oxford, U.K. The meeting will focus on advances in the field and current opportunities and challenges in developing RNAi-based strategies for use in understanding ...

We present experimental work that reveals the benefits of performing magnetic force microscopy measurements employing the torsional resonance mode of cantilever oscillation. This approach provides two clear advantages: the ability of performing magnetic imaging without topography-related interference and the significant lateral resolution improvement (approximately 15%). We believe that this wo...

The interest in micro- and nano-devices based on biodegradable polymers for in vivo applications is growing rapidly and the key to these applications lies in the fashioning of features analogous to the size of cells. This paper presents fabrication techniques for leveraging micro- and nanostructures on biodegradable polymers. Innovative approaches such as replication molding, laser interference...

Future industrial radio systems for Industry 4.0 applications will heavily rely on the management of shared spectrum to provide coexistence of different wireless communication systems and unknown wireless transmitters. A crucial component for successful coexistence management is the estimation of the spectrum of interest to identify active wireless systems and potential interference sources. Mo...

In this paper the logical process structure of the Chandy-Misra parallel simulation algorithm has been studied. The excessive synchronization caused by the algorithm is avoided by minimizing the number of connections between logical processes. The amount of connections are reduced by restricting the direct communication of the logical processes to their neighborhoods. Two methods, message path ...

In this thesis I exam ined the effects of task switching on people’s ability to ignore irrelevant distractors. Load theory proposes that distractor interference critically depends on the availability of executive control to minimise the effects of irrelevant stimuli (e.g. Lavie, 2000). Much work on task switching suggests that task switching demands executive control in order to prepare for and...
