Research ArticleOpen accessIn the abstractA Price Hedging Model in Dynamic MarketKuo-Wei Lin, Kuang-Jung Tseng, Szu-Cheng ChengProblem statement: Pricing is a problem when a firm has to set a price for the first time. This happens when the firm develops or acquires a new product, introduces its regular product into a new distribution or geographical area, or enters bids on the new contract work. Many companies try to set the price to maximize current profits. They … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 3 Aug 2012 · 6,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Applications of Differential Subordination and Differential OperatorM. Darus, R. W. IbrahimProblem statement: The object of this study is to obtain certain differential subordinations. Approach: Here we use known generalized differential operator given by Darus and Ibrahim and well known lemmas given by Miller and Mocanu. Results: We will pose several results on subordination theorems. Conclusion: Many other results can be obtained by using the operator defined. …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 1 Mar 2012 · 7,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Applications of Spanning Trees in Complete and Complete Bipartite GraphsS. N. DaoudProblem statement: The number of spanning trees τ(G) in graphs (networks) is an important invariant, it is also an important measure of reliability of a network. Approach: Using linear algebra and matrix analysis techniques to evaluate the associated determinants. Results: In this study we derive simple formulas for the number of spanning trees of complete graph Kn and complete bipartite … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 15 Feb 2012 · 7,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractComplexity of Cocktail Party Graph and Crown GraphS. N. DaoudProblem statement: The number of spanning trees τ(G) in graphs (networks) was an important invariant. Approach: Using the properties of the Chebyshev polynomials of the second kind and the linear algebra techniques to evaluate the associated determinants. Results: The complexity, number of spanning trees, of the cocktail party graph on 2n vertices, given in detail in the text was proved. … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 12 Dec 2011 · 7,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompositional Analysis on Ancient Bricks from Candi Sungai Mas (Site 32/34), Bujang Valley, KedahZuliskandar Ramli, Nik Hassan Shuhaimi Nik Abd. Rahman, Adnan Jusoh, Mohd. Zobir HusseinProblem statement: The significance of Kampung Sungai Mas as an importance archaeology site in Lembah Bujang was revealed in the year 1979 when a cannel was built along Kampung Sungai Mas area. During the construction study of this cannel, thousands of ceramic pieces from India, Middle East, China, Southeast Asia and Europe was discovered, pieces of glasses from Middle East … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 12 Dec 2011 · 9,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Local Wisdom for Production of Condiment Isan' Food Ingredient into CommercialNitchapanrawee PhengpholProblem statement: The problem of the research derives from a lack of study and understanding about the production of condiment Isan food and ingredients being introduced into commercial, even though Isan food is popular among consumers widespread both inside and outside the country. The government introduced a policy to expand trade to create an export value of Isan products. The … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 7,217 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Parametric p-Valent Meromorphic FunctionsPoonam SharmaProblem statement: In this research, we studied parametric p-valent meromorphic functions Pαf by considering two classes Mαp (β) and Mαp (λ,A) . Approach: With the help of Jack’s Lemma an inclusion relation for the class Mαp was obtained and it is shown that this class is closed by an integral operator Ic. Results: A subordination result for the class Mαp … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,033 accessesView PDFCite

Research ArticleOpen accessIn the abstractEfficient Reversible Montgomery Multiplier and Its Application to Hardware CryptographyNoor Muhammed Nayeem, Lafifa Jamal, Hafiz Md. Hasan BabuProblem Statement: Arithmetic Logic Unit (ALU) of a crypto-processor and microchips leak information through power consumption. Although the cryptographic protocols are secured against mathematical attacks, the attackers can break the encryption by measuring the energy consumption. Approach: To thwart attacks, this study proposed the use of reversible logic for designing the ALU of a crypto-processor. Ideally, reversible circuits do not … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,852 accessesView PDFCite
