引用

Journal of Software Engineering and Applications 2013年第7期6卷 343-348页

作者： Wasim ahmad Ashraf Zia usman Khalid Department of Computer Sciences Abdul Wali Khan University Mardan Shankar Campus Khyber Pakistan

Social Networking is a harbinger to a more recent era in the area of computing where allocated and central resources are used in an exclusive manner. Millions of people around the globe with access to the internet are part of one or more social networks. They have permanent online accounts on Facebook and Twitter etc. where they create profiles, share photos, videos, useful links, their thoughts and spend hours catching up with what their friends are doing in their lives. The problem arise when somebody needs specific information about any city inside a country e.g. Where he/she can live? What he/she can eat? Where is the best place for outing? What are the special events relevant to that region? And may be any other help? In this paper we suggest a social network called Google map based social network (GMBSN), where users can choose their desired city of interest from the list. The selected city will be highlighted on Google map. After choosing any city from the map, the user will be able to select any category from the list and start finding and sharing information about the desired city of any country.

Leaching of styrene and other aromatic compounds in drinking water from PS bottles

引用

Journal of Environmental Sciences 2007年第4期19卷 421-426页

作者： Maqbool ahmad ahmad S. Bajahlan Environmental Control Department Directorate General for Royal Commission at Yanbu P.O.Box 30031 Yanbu Al-SinaiyahKingdom of Saudi Arabia

Bottled water may not be safer, or healthier, than tap water. The present studies have proved that styrene and some other aromatic compounds leach continuously from polystyrene （PS） bottles used locally for packaging. Water sapmles in contact with PS were extracted by a preconcentration technique called as ＂purge and trap＂ and analysed by gas chromatograph-mass spectrometer （GC/MS）. Eleven aromatic compounds were identified in these studies. Maximum concentration of styrene in PS bottles was 29.5 μg/L. Apart from styrene, ethyl benzene, toluene and benzene were also quantified but their concentrations were much less than WHO guide line values. All other compounds were in traces. Quality of plastic and storage time were the major factor in leaching of styrene. Concentration of styrene was increased to 69.53 μg/L after one-year storage. In Styrofoam and PS cups studies, hot water was found to be contaminated with styrene and other aromatic compounds. It was observed that temperature played a major role in the leaching of styrene monomer from Styrofoam cups. Paper cups were found to be safe for hot drinks.

Overcoming the limits of piezoelectric composites

引用

National Science Review 2023年第9期10卷 118-119页

作者： ahmad Safari Department of Materials Science and Engineering Rutgers University

The study of piezoelectric composites traces its origins back to the 1970s, when the concept of combining ceramics and polymers to introduce self-connectivity was first proposed [1-3].Creating composites using polymers as the matrix and ferroelectric ceramics as fillers has proven to be an effective approach for improving the electromechanical coupling performance of piezoelectric materials.

The Strategic Form of Quantum Prisoners' Dilemma

引用

Chinese Physics Letters 2013年第5期30卷 4-9页

作者： ahmad Nawaz National Centre for Physics Quaid-i-Azam University CampusIslamabad 45320Pakistan

In a normal form, prisoners' dilemma (PD) is represented by a payoff matrix showing players' strategies and payoffs. To obtain the distinguishing trait and strategic form of PD, certain constraints are imposed on the elements of its payoff matrix. We quantize PD by a generalized quantization scheme to analyze its strategic behavior in the quantum domain. The game starts with a general entangled state of the form |ψ>=cos(ξ/2)|00>+sin(ξ/2)|11> and the measurement for payoffs is performed in entangled and product bases. We show that for both measurements, there exist respective cutoff values of entanglement of the initial quantum state up to which the strategic form of the game remains intact. Beyond these cutoffs the quantized PD behaves like the chicken game (CG) up to another cutoff value. For the measurement in the entangled basis the dilemma is resolved for sinξ >1/7 with Q⊗Q as a Nash Equilibrium (NE). However, the quantized game behaves like PD when sinξ >1/3;whereas in the range 1/7

Effect of SrCO_3 addition on the dynamic compressive strength of ZTA

引用

International Journal of Minerals,Metallurgy and Materials 2016年第4期23卷 481-489页

作者： Ali Arab Roslan ahmad Zainal Arifin ahmad School of Mechanical Engineering Universiti Sains Malaysia Engineering Campus Structural Materials Niche Area School of Materials and Mineral Resources Engineering Universiti Sains Malaysia Engineering Campus

Ceramic parts usually experience dynamic load in armor applications. Therefore, studying the dynamic behaviors of ceramics is important. Limited data are available on the dynamic behaviors of ceramics; thus, it is helpful to predict the dynamic strength of ceramics on the basis of their mechanical properties. In this paper, the addition of SrCO3 into zirconia-toughened alumina（ZTA） was demonstrated to improve the fracture toughness of ZTA due to the formation of the SrAl12O19（SA6） phase. The porosity of ZTA was found to be increased by the addition of SrCO3. These newly formed pores served as the nucleation sites of cracks under dynamic load; these cracks eventually coalesced to form damaged zones in the samples. Although the KIC values of the samples were improved, the dynamic strength was not enhanced because of the increase in porosity; in fact, the dynamic strength of ZTA ceramics decreased with the addition of SrCO3.
