Effects of soil compaction in the sub-humid cropping environment in Pakistan on uptake of NPK and grain yield in wheat (Triticum aestivum): II Alleviation. (2009)

Ahmed, N., Hassan, F., Belford, Robert

Alleviation of soil compaction can be achieved through application of appropriate measures which will vary from soil to soil and with the socio-economic factors of the farmers. The effects of...

Effect of soil compaction in the sub-humid cropping environment in Pakistan on uptake of NPK and grain yield in wheat (Triticum aestivum): I Compaction. (2009)

Ahmed, N., Hassan, F.U., Belford, Robert

Soil compaction is a major cause of decrease in crop yield. The most serious cause of soil compaction is continuous ploughing at the same depth which affects bulk density, porosity and root...

(Guest Editors) Floating Textures (2008)

M. Eisemann, B. De Decker, M. Magnor, P. Bekaert, E. De Aguiar, N. Ahmed, ...

We present a novel multi-view, projective texture mapping technique. While previous multi-view texturing approaches lead to blurring and ghosting artefacts if 3D geometry and/or camera calibration...

Low Power Pattern Generation for BIST Architecture (2008)

N. Ahmed, M. H. Tehranipour, M. Nourani

A new low power test pattern generator using a linear feedback shift register (LFSR), called LP-TPG, is presented to reduce the average and peak power of a circuit during test. The correlation...

Frequency Driven Repeater Insertion for Deep Submicron (2008)

N. Ahmed, Ahmed Tehranipour Zhou, D. Zhou, M. Nourani

Repeaters are now widely used to decrease delay and increase the performance of long interconnects. The maximum operating frequency is limited by the longest wire between two repeaters. The main goal...

Addressing Workers' Rights in the Textile and Apparel Industries: Consequences for the Bangladesh Economy (online first) (2008)

Ahmed, N., Peerlings, J.H.M.

This paper applies a CGE model to analyze the effects of better addressing worker¿s rights in Bangladesh¿s textile and apparel industries. Results show that an increased minimum wage for unskilled,...

Robot Motion Planning (2007)

N. Ahmed

Robotics has blossomed as a discipline in Computer Science from the fiction world of Isaac Asimov and grown rapidly in response to the increasing demand for industrial automation. It all started with...

Motion planning in Prototypical Corridors (2007)

N. Ahmed, A. Sowmya

We discuss the motion planning of a rectangular moving object in certain prototypical situations arising in a 2-D isothetic workspace. We have suggested three possible motion strategies involving...

Intra-domain Bandwidth Management in Differentiated Services Network (2007)

S. Jha, M. Hassan, N. Ahmed

In absence of any link layer traffic controls or priorityqueuing mechanism in LAN infrastructure (such as shared media LAN), Subnet Bandwidth Management based approach of managing bandwidth is...

Predicting Gran alkalinity and calcium concentrations in river waters over a national scale using a novel modification of the G-BASH model (2006)

Cresser, M.S., Ahmed, N., Smart, R.P., Arowolo, T., Calver, L.J., Chapman, P.J.

Monthly stream water calcium and Gran alkalinity concentration data from 11 sub-catchments of the Nether Beck in the English Lake District have been used to appraise the transferability of the...

Testing SoC Interconnects for Signal Integrity Using Boundary Scan (2003)

M. H. Tehranipour, N. Ahmed, M. Nourani

As the technolog isshrinking toward 50 nm and theworking frequency isg(RF into multiglti(DFF rangZ the effect of interconnects on functionality and performance of system-on-chips isbecoming dominant....

Experimental study of weak antilocalization effect in a high mobility InGaAs/InP quantum well (2002)

Studenikin, S. A., Coleridge, P. T., Ahmed, N., Poole, P., Sachrajda, A.

The magnetoresistance associated with quantum interference corrections in a high mobility, gated InGaAs/InP quantum well structure is studied as a function of temperature, gate voltage, and angle of...

Ahmed, N., Pansino, F., Clyde, Riley, Murthi, P., Quinn, M. A., Rice, G. E., ...

Recent evidence suggests that integrins are involved in the multi-step process of tumour metastasis. The biological relevance of αv integrins and associated β-subunits in ovarian cancer metastasis...
