this study was carried out to evaluate the effects of tillage practices (with different depths) on soil penetration resistance, technical parameters and grain yield of wheat crop. the experiment was conducted as a randomized complete block design with three replications for two years. treatments included: moldboard plow fallowed by two passes of disc harrow and leveler (ct), two passes of disc ...

OBJECTIVE To describe the epidemiology and associated clinical features of gonorrhoea and chlamydial infection and to develop a profile of sexually transmitted diseases (STDs) in an outer London health district. DESIGN Hospital-based retrospective study. SETTING Genitourinary medicine clinic, Northwick Park Hospital, Harrow and Brent Health Authority. SUBJECTS 70 male and female individua...

We study the one-shot zero-error classical capacity of quantum channels assisted by quantum non-signalling correlations, and the reverse problem of simulation. Both lead to simple semi-definite programmings whose solutions can be given in terms of the conditional min-entropies. We show that the asymptotic simulation cost is precisely the conditional min-entropy of the Choi-Jamiołkowski matrix o...

We describe an application that combines velocity data from a Windprofiler radar and a NEXRADII Doppler radar to compute 3D optical flow of moving severe weather. Windprofiler data improves the recovery of the velocity component in the upwards direction in the optical flow, where Windprofiler data is believed to be more accurate. We demonstrate this quantitatively using synthetic radar data and...

It is well-known that during tillage operations suprising items may appear below the soil surface in agricultural lands. Sometimes a stone/rock or solid root can cause major damage to equipments. These rocks and roots impacts on equipment. In order eliminate minimize impact of these forces, shock absorbing equipment used provides connection between disc harrow chassis. The most commonly materia...

Aim of study: To develop an instrumentation system comprising three force sensing elements to measure the draught resistance any tillage and seeding tools during field operation by connecting one element each three-point linkage tractor.
 Area Department AgFE, Indian Institute Technology, Kharagpur, India
 Material methods: Commercial S-type transducers were packed laterally in betwee...

We present two new quantum algorithms. Our first algorithm is a generalization of amplitude amplification to the case when parts of the quantum algorithm that is being amplified stop at different times. Our second algorithm uses the first algorithm to improve the running time of Harrow et al. algorithm for solving systems of linear equations from O(κ logN) to O(κ log κ logN) where κ is the cond...
