Research ArticleOpen accessIn the abstractThermal Energy Loss in the Steam Valves and its EffectsGalip Temir, Durriye BilgeIn this study, the effects of thermal losses in steam valves for flow have been analyzed. In a set of experiment built to achieve this, pressure and condensate values have been calculated in different temperatures for insulated and non-insulated cases in three different nominal diameter steam valves. The amount of energy lost from the valve surface in the natural convection … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractChildren Perception on TV Advertisement: The Impact of Age, Gender and Parental InfluenceAhasanul Haque, Ali KhatibiThis study examined two components of understanding TV advertising: the recognition of the difference between programmes and commercials and the comprehension of advertising intent. ANOVA analyses were performed to assess the effect on age, gender, parent-child interaction and parental control over children of TV programme watching. Research found that majority of children aged between five and eight have some understanding … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Causal Relationship between Inflation and Productivity: An Empirical Approach for RomaniaNikolaos DritsakisThis study attempts to analyze the relationship between the productivity and the inflation of a transition country of the European Union as Romania. For this purpose we use quarterly data since 1990: IV in 2003: I and the causality analysis, which is based on an error correction model. The results of the empirical analysis showed that there is a causal … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,096 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgramming of the Generalized Nonlinear Paraxial Equation for the Formation of Solitons with MathematicaFrederick Osman, Robert BeechThis study presents the nonlinearity and dispersion effects involved in the propagation of optical solitons which can be understood by using a numerical routine to solve the Generalized Nonlinear Paraxial equation. A sequence of code has been developed in Mathematica, to explore in depth several features of the optical soliton’s formation and propagation. These numerical routines were implemented through the … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractFurther Improvements in Temperature Calculation During Cooling of Fish PackagesF. A. Ansari, K. A. Abbas, J. Bakar et al.In an earlier study, it was demonstrated that the empirical approach used to calculate the surface film conductance resulted into a higher value compared to those obtained from the other methods available in the literature. During further investigations, surface film conductance values were found to gradually decrease with a fall in temperature. When this non-linear variation was used to develop … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving Linear Programming Problems on the Parallel Virtual Machine EnvironmentJrJung Lyu, Hsing Luh, Ming-Chang LeeThis study developed a parallel algorithm to efficiently solve linear programming models. The proposed algorithm utilizes the Dantzig-Wolfe Decomposition Principle and can be easily implemented in a general distributed computing environment. The analytical performance of the well-known method, including the speedup upper bound and lower bound limits, was derived. Numerical experiments are also provided in order to verify the complexity … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,841 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Optimum Numbers of Stages in Vapour Compression Refrigeration SystemsDurriye Bilge, Galip TemirIn this study, cases of single-stage and multi-stage compression have been compared and contrasted through various angles while concentrating on refrigeration systems with 600 kW cooling capacity and working with ammonia. For five different numbers of stages, power consumption, costs of investment, operation and maintenance (O and M), COP and 2nd law efficiencies have been calculated. As the amount of … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractRevisiting the Unit Root Hypothesis and Structural Break: Asia and Emerging Economies Foreign Exchange MarketsChristopher Gan, Sirimon Treepongkaruna, Hue Hwa Au YongThis study examines the stationary of ten Asian and for emerging Foreign Exchange (FX) rates during the 1990s. The paper employs the Augmented Dickey-Fuller (ADF) unit root test to the following FX rates: Hong Kong Dollar (HKD) Japanese Yen (JPY), South Korean won (KRW) new Taiwan dollar (TWN), Chinese Renminbl (CHR), Indonesia Rupiah (IDR), Malaysian Ringgit (MYR), Singapore Dollar (SGD), … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 6,954 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Mechanism of Stock Market Integration: Evidence for the Taiwan and U.S. Stock MarketMin-Hsien Chiang, Rung-Ho Lai, Hsiao-Ching LeeThis study investigates the sources of the comovement of the Taiwan and U.S. stock market. The empirical evidence shows that both economic fundamentals and equity risk premiums can act as transmission mechanisms of both markets. In the meantime, the financial integration is much stronger than real economic integration. Moreover, the deregulation of foreign investments in Taiwan and the Southeast Asian … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,199 accessesView PDFCite
Review ArticleOpen accessIn the abstractMitochondria are Naturally Micro Robots - A reviewRaffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuThe mitochondrion is a natural robot (cell) with a length of about one micron. Between organisms (plant, animal or human) with its organs and the atomic and molecular components are positioned based cells, which are building all the necessary organs body. Years ago, medical specialists who are studying organ disease have considered that is caused by impaired organ or related … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 18 Nov 2016 · 8,838 accessesView PDFCite
