A Web Smart Space Framework for Intelligent Search Engines
M. Asif Naeem,Noreen Jamil
International Journal of Emerging Sciences , 2011,
Abstract: A web smart space is an intelligent environment which has additional capability of searching the information smartly and efficiently. New advancements like dynamic web contents generation has increased the size of web repositories. Among so many modern software analysis requirements, one is to search information from the given repository. But useful information extraction is a troublesome hitch due to the multi-lingual; base of the web data collection. The issue of semantic based information searching has become a standoff due to the inconsistencies and variations in the characteristics of the data. In the accomplished research, a web smart space framework has been proposed which introduces front end processing for a search engine to make the information retrieval process more intelligent and accurate. In orthodox searching anatomies, searching is performed only by using pattern matching technique and consequently a large number of irrelevant results are generated. The projected framework has insightful ability to improve this drawback and returns efficient outcomes. Designed framework gets text input from the user in the form complete question, understands the input and generates the meanings. Search engine searches on the basis of the information provided.
First Integrals for Two Linearly Coupled Nonlinear Duffing Oscillators
R. Naz,I. Naeem,F. M. Mahomed
Mathematical Problems in Engineering , 2011, DOI: 10.1155/2011/831647
Abstract: We investigate Noether and partial Noether operators of point type corresponding to a Lagrangian and a partial Lagrangian for a system of two linearly coupled nonlinear Duffing oscillators. Then, the first integrals with respect to Noether and partial Noether operators of point type are obtained explicitly by utilizing Noether and partial Noether theorems for the system under consideration. Moreover, if the partial Euler-Lagrange equations are independent of derivatives, then the partial Noether operators become Noether point symmetry generators for such equations. The difference arises in the gauge terms due to Lagrangians being different for respective approaches. This study points to new ways of constructing first integrals for nonlinear equations without regard to a Lagrangian. We have illustrated it here for nonlinear Duffing oscillators.
An analytical treatment of the neutrino masses and mixings
Jora, Renata;Schechter, Joseph;Shahid, M. Naeem
High Energy Physics - Phenomenology , 2013,
Abstract: We obtain analytical formulas which connect the neutrino masses and the leptonic mixing matrix with the entries in the mass matrix for the approximation in which the charged lepton mixing matrix is the unit matrix. We also extract the CP violation phase and determine the conditions in which this is present.
Efficacy of Different Herbicides for Control of Weeds in Srghum (Sorghum bicolor L) under Rainfed Conditions
Abdul Shakoor,Shamsul Islam,M. Naeem
Pakistan Journal of Biological Sciences , 2000,
Abstract: Sorghum variety PARC-SS-2 was subjected to five different herbicides with different levels of active ingredients for control of weeds in comparison with hand-weeded and un-weeded check during summer seasons of 1997 and 1998 at the National Agricultural Research Centre Islamabad. Weed population significantly reduced from 73.79 to 90.04 per cent due to the application of various herbicides and by 78.69 per cent due to hand weeding over the un-weeded check. Reduction in weed population per unit area was more in the increased levels of herbicides. All treatments gave significantly higher grain yields than the unweeded check in both the years. The grain yield of the plots treated with Metolachlor + Atrazine @ 1.00 kg ha-1 was significantly more than the plots treated with either dose of other herbicides or hand weeded in both the years. At the two levels of herbicides the increase in yield ranged from 845 to 1144 kg ha-1 through Metolachlor + Atrazine @ 1.00 kg ha-1, 328 to 1144 kg ha -1 by hand weeding and 665 to 1750 kg ha-1 by Metolachlor + Atrazine @ 0.75 kg ha-1, as compared to no weeding. As such, increase in the levels of herbicides increased the yield. It was found that the yield from hand-weeded plots was more than all the herbicides at either level. However, Metolachlor + Atrazine @ 1.00 kg ha-1 (ai), higher level resulted significantly higher yields than the hand weeded ones. The effect of the lower level of Metolachlor + Atrazine @ 0.75 kg ha-1 (ai), was at par with hand-weeded plots. Though the difference was there, but it was non-significant statistically. The higher doses of these herbicides which have resulted significant grain yield, could be considered for higher return. The economic analysis revealed that there was increased net income from the plots treated with herbicides or hand weeded over the unweeded check. The highest marginal rate of return (MMR) of 404.16 per cent was obtained from T3 (the plots treated with Metolachlor + Atrazine @ 1.00 kg ha-1 (ai) followed by T6 (Metolachlor + Atrazine @ 0.75 kg ha-1 (ai) with MRR of 297.22 per cent while that of hand weeded treatment the MRR was 229.54 per cent.
Electrical transport and optical studies of ferromagnetic Cobalt doped ZnO nanoparticles exhibiting a metal-insulator transition
M. Naeem,S. K. Hasanain,A. Mumtaz
Physics , 2007, DOI: 10.1088/0953-8984/20/02/025210
Abstract: The observed correlation of oxygen vacancies and room temperature ferromagnetic ordering in Co doped ZnO1-o nanoparticles reported earlier (Naeem et al Nanotechnology 17, 2675-2680) has been further explored by transport and optical measurements. In these particles room temperature ferromagnetic ordering had been observed to occur only after annealing in forming gas. In the current work the optical properties have been studied by diffuse reflection spectroscopy in the UV-Vis region and the band gap of the Co doped compositions has been found to decrease with Co addition. Reflections minima are observed at the energies characteristic of Co+2 d-d (tethrahedral symmetry) crystal field transitions, further establishing the presence of Co in substitutional sites. Electrical transport measurements on palletized samples of the nanoparticles show that the effect of a forming gas is to strongly decrease the resistivity with increasing Co concentration. For the air annealed and non-ferromagnetic samples the variation in the resistivity as a function of Co content are opposite to those observed in the particles prepared in forming gas. The ferromagnetic samples exhibit an apparent change from insulator to metal with increasing temperatures for T>380K and this change becomes more pronounced with increasing Co content. The magnetic and resistive behaviors are correlated by considering the model by Calderon et al [M. J. Calderon and S. D. Sarma, Annals of Physics 2007 (Accepted doi: 10.1016/j.aop.2007.01.010] where the ferromagnetism changes from being mediated by polarons in the low temperature insulating region to being mediated by the carriers released from the weakly bound states in the higher temperature metallic region.
Conditional linearizability criteria for a system of third-order ordinary differential equations
F. M. Mahomed,I. Naeem,Asghar Qadir
Mathematics , 2007, DOI: 10.2991/jnmp.2008.15.s1.11
Abstract: We provide linearizability criteria for a class of systems of third-order ordinary differential equations (ODEs) that is cubically semi-linear in the first derivative, by differentiating a system of second-order quadratically semi-linear ODEs and using the original system to replace the second derivative. The procedure developed splits into two cases, those where the coefficients are constant and those where they are variables. Both cases are discussed and examples given.

Naeem M. Desai,William R. B. Lionheart
Mathematics , 2015,
Abstract: We give an explicit plane-by-plane filtered back-projection reconstruction algorithm for the transverse ray transform of symmetric second rank tensor fields on Euclidean 3-space, using data from rotation about three orthogonal axes. We show that in the general case two axis data is insufficient but give an explicit reconstruction procedure for the potential case with two axis data

Sami ul Haq, Mushtaq Raza, Asraf Zia, M. Naeem Ahmed Khan
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.410069
Abstract: A number of companies have employed Global Software Development (GSD) methodology as a useful tool for their software development practices. GSD is a contractual relationship between client and vendor organizations in which a client outsources all or some part of its software development activities to a vendor. The vendor in return provides the agreed services in lieu of certain amount of remuneration. The main reasons to select the GSD technique include reduced cost, faster development and access to skilled manpower. Though GSD is emerging as an effective technique, but it suffers from many challenges like poor communication, lack of trust and coordination. These challenges pose serious risk to the smooth execution of the GSD projects. In this paper, we present a comparative study on GSD to highlight its merits and demerits. Our findings reveal that much of the research in this area has been focused on addressing issues faced by client organizations, however, vendor side in the GSD relationship is much ignored due to which this area is still immature; and, hence, further research work is required to be undertaken to address the issues faced by the vendor organizations.

M. Tahir Jan,M. Naeem,M. Idrees Khan,Rashid Mehmood
Asian Journal of Plant Sciences , 2002,
Abstract: During the crop season leafhoppers and aphids were found the serious pests of potato crop with seasonal mean of 15.55 per branch and 5.21 per sweep, in control plot (monoculture) respectively. The field cricket was also found damaging the tubers but the population was low. Potato crop was mix grown with berseem (PBM) and radish (PRM) as control strategy. Over 70% reduction in leafhopper population occurred due to inter-cropping tactics as compared to control. However among the inter-cropping system, PBM combination was found better than PRM.
