Face recognition technology has evolved as an enchanting solution to perform identification and the verification of identity claims. By advancing the feature extraction methods and dimensionality reduction techniques in the pattern recognition applications, number of facial recognition systems has been produced with distinctive degrees of success. In this paper, we have presented the biometric face recognition approach based on Multilinear Principal Component Analysis (MPCA) and Locality Preserving Projection (LPP) which enhance performance of face recognition. The methodology of the approach consists of face image preprocessing, dimensionality reduction using MPCA, feature Extraction using LPP and face recognition using L2 similarity distance measure. The proposed approach is validated with FERET and AT&T database of faces and compared with the existing MPCA and LDA approach in performance. Experimental results show the effectiveness of the proposed approach for face recognition with good recognition accuracy. © 2011 IEEE. Source

Purpose - The purpose of this paper is to assess the use of electronic information resources and facilities by humanities scholars at the University of the Punjab, Lahore, Pakistan. Design/methodology/approach - A questionnaire survey of faculty from arts and humanities departments at the University of the Punjab was conducted. In total, 62 faculty and research staff participated. Findings - The results correspond with previous studies conducted in other countries. The humanists still stick to the printed information sources but they pay good attention to electronic resources. Most of them have access to computer and internet at office and home. They are regular users of a variety of electronic technologies. Although faced with many problems, the humanists perceive that modern technology made their work easier. Research limitations/implications - The study is based only on the humanities faculty in a large university of Pakistan. The survey should be replicated on a larger sample for generalization. Practical implications - Keeping in view the positive trend of humanists towards modern technology, universities and libraries should give more funding to provide electronic resources and facilities in the arts and humanities discipline. Special training programmes for humanists should be organized. Originality/value - This is the first study on this topic in Pakistan. The results can be useful to design services and facilities in humanities libraries and information centres in Pakistan and other developing countries. © Emerald Group Publishing Limited 0264-0473.

This study describes a new approach, i.e., the intuitionistic fuzzy success index method, for human reliability estimation using intuitionistic fuzzy sets. In our study, two offshore platform muster scenarios, i.e., "man overboard" and "gas release," were considered as an assessing and a reference task, respectively. Herein,we aggregated the weightings and ratings of various performance shaping factors concerned with "man overboard" to obtain the intuitionistic fuzzy success index (IFSI) of the assessing task. Thereafter, we considered the pooled discrete intuitionistic fuzzy subset of the IFSI as the causal event and the known human reliability as the resultant event.Using this,we generate an intuitionistic fuzzy relation between the two events of the concerned task. The composition of the discrete intuitionistic fuzzy subset of the IFSI and the intuitionistic fuzzy relation gave the human reliability in the assessing task man overboard.© 2013 IEEE. Source

Reactions of [N12] macrocyclic ligand, L 2HClO4, with RuCl 3, PdCl2, K2[PtCl6], [K 2PtCl4] as well as [M(Ph3P)2Cl 2] (M = Pd or Pt), and [Ru(Ph3P)3Cl 2] produces bimetallic complexes whose analytical data are consistent with the molecular formulae as Ru2LCl4(ClO 4)2 (I), Pd2LCl2(ClO4)2 (II), Pt2LCl6(ClO4)2 (III), Pt 2LCl2(ClO4)2 (IV) and Ru 2LCl2(ClO4)2 (V). Reactions of the ligand with the precursors [M(Ph3P)2Cl2] (M = Pd or Pt), and [Ru(Ph3P)3Cl2], has released all the Ph3P ancillary ligand in solution. Magnetic moment, IR and UV-visible spectroscopic data confirms the encapsulation of metal ions in the macrocyclic cavities through chelation from aza groups of the unsymmetrical imine (CN) and amine (CNHC) functions. The macrocyclic moiety has accommodated both the lower as well as higher oxidation states of metal ions, i.e., Ru(II), Ru(III), Pd(II), Pt(II), and Pt(IV), which shows its flexible nature and capability to form stable complexes.

It is more than 20 years since the first cord blood transplant (CBT) was performed, following the realization that cord blood (CB), which is normally wasted, is rich in progenitor cells and capable of rescuing haematopoiesis. Since then it has been appreciated that CB is rich in stem cells, and has many other features not the least of which is its ability to rescue the transplanted patient without a rigid need for full human lymphocyte antigen (HLA) compatibility. Also it is easily accessible, relatively free from infections and poses no medical risk to the donor. However, the quantity of the stem cells is rather small, thus predominantly restricting its use to children or adults requiring double units. In Oman, we have taken a keen interest in stem cell research and also CBT. We see such activities as an avenue for our patients, for whom a compatible bone marrow (BM) or a peripheral blood donor cannot be found, to have an alternative in the form of CBT. This has encouraged us to establish a national voluntary cord blood bank (CBB) which is a valuable option open to a selected group of patients, as compared to the controversial private CBB. This national CBB will have a better representation of HLA-types common in the region, an improvement on relying on banks in other countries. Considering the need for stem cell transplant/therapy in this country, it is only appropriate that this sort of bank is established to cater for some of these requirements. Source
