International Journal of Biomathematics 2016年第2期9卷 159-173页

作者： Qazi Mahmood ul Hassan syed Tauseef Mohyud-Din Department of Mathematics Faculty of Sciences HITEC University Taxila 47080 Pakistan

This paper is the spectator of the arrangement of an efficient transformation and exfunction technique to build up generalized exact solutions of the biological population model equation. Computational work and subsequent numerical results re-identify the effectiveness of proposed algorithm. It is pragmatic that recommended plan is greatly consistent and may be comprehensive to other nonlinear differential equations of fractional order.

Certificate revocation in vehicular ad hoc networks techniques and protocols: a survey

引用

Science China(Information Sciences) 2017年第10期60卷 7-24页

作者： Taimur KHAN Naveed AHMAD Yue CAO syed Asim JALAL Muhammad ASIF Sana ul HAQ Haitham CRUICHSHANK Department of Computer Sciences University of Peshawar Department of Computer and Information Sciences Northumbria University Institute of Communication Systems University of Surrey

Vehicular Ad hoc Networks(VANETs) are special kind of Mobile Ad hoc Networks(MANETs),where vehicles communicate with each other in ad hoc formation. VANETs consist of Vehicles and Road Side Units(RSUs) that assist in the network management. Vehicles communicate with each other and RSUs, with the aim to provide infotainment and safety services on road. Security is an important consideration in VANETs as safety of humans(passengers) is an important issue. Vehicular Public Key Infrastructure(VPKI) is an adapted form of Public Key Infrastructure(PKI) used to achieve the key management and security services in *** generation and revocation is one of the primary functions of VPKI. Certificate revocation is used for revoking the malicious nodes and terminate their access rights to the network. In this paper we classify revocation schemes in a novel way into centralized and decentralized manners. This paper covers a survey of different certificate revocation schemes, and provides an overview of the research in the area of certificate revocation in VANETs.

Enhanced urease inhibition activity of Ag nanomaterials capped with N-substituted methyl 5-acetamido-β-resorcylate

引用

Progress in Natural Science:Materials International 2019年第2期29卷 129-137页

作者： syeda Sohaila Naz Muhammad Raza Shah Nazar ul Islam syed Sartaj Alam Nanosciences and Technology Department National Centre for Physics Quaid-i-Azam University Campus ICCBS H.E.J.Research Institute of Chemistry University of Karachi Institute of Chemical Sciences University of Peshawar Sarhad University of Science and Information Technology Department of Plant Pathology The University of AgriculturePeshawar Pakistan

Medically, bacterial ureases are important virulent factors and are used for treatment of peptic ulcers and urinary tones. Reported urease inhibitors are associated with various side effects including antibiotic resistance as a major one. Still there is an urgent need to synthesize new urease inhibitors. In this context we have synthesized new urease inhibitor i.e. AgL that is composed of Ag nanomaterials capped with N-substituted methyl 5-acetamido-β-resorcylate(L). The conjugation of L to silver was confirmed through FTIR, UV–vis and TEM *** silver nanomaterials(Ag) were also prepared. The stability of AgL nanostructures was determined against various parameters(temperature, high salt concentration, pH) and found to be stable. The in vitro antimicrobial(antibacterial, antifungal), enzyme inhibition(xanthine oxidase, urease, carbonic anhydrase, α-chymotrypsin,cholinesterase) and antioxidant activities of AgL were investigated and compared with Ag, L and standard *** comparison to other bioactivities, AgL shows statistically enhanced selective enzyme inhibition activity against urease enzyme. Urease inhibition activity of AgL was significantly greater than standard drug(thiourea),L and Ag. On a per weight basis, AgL required about 11–18 times less amount of L for inhibition of urease enzyme.

On the Constant Metric Dimension of Generalized Petersen Graphs P(n,4)

引用

Acta Mathematica Sinica,English Series 2014年第7期30卷 1145-1160页

作者： Saba NAZ Muhammad SALMAN Usman ALI Imran JAVAID syed Ahtsham-ul-Haq BOKHARY Center for Advanced Studies in Pure and Applied Mathematics Bahauddin Zakariya University

In this paper, we consider the family of generalized Petersen graphs P（n,4）. We prove that the metric dimension of P（n, 4） is 3 when n = 0 （mod 4）, and is 4 when n = 4k ＋ 3 （k is even）.For n = 1,2 （mod 4） and n = 4k ＋ 3 （k is odd）, we prove that the metric dimension of P（n,4） is bounded above by 4. This shows that each graph of the family of generalized Petersen graphs P（n, 4） has constant metric dimension.

In this paper, we are dealing with the study of the metric dimension of some classes of regular graphs by considering a class of bridgeless cubic graphs called the flower snarks Jn, a class of cubic convex polytopes considering the open problem raised in [M. Imran et al., families of plane graphs with constant metric dimension, Utilitas Math., in press] and finally Harary graphs H5,n by partially answering to an open problem proposed in Ⅱ. Javaid et al., Families of regular graphs with constant metric dimension, Utilitas Math., 2012, 88： 43-57]. We prove that these classes of regular graphs have constant metric dimension.
