http://ijaems.com/ Open Access international Journal to publish research paper en-us February 2017 Internet has been widely applied in various fields, more and more network security issues emerge and catch people’s attention. However, adversaries often hide themselves by spoofing their own IP addresses and then launch attacks. For this reason, researchers have proposed a lot of trace back schemes to trace the source of these attacks. Some use only one packet in their packet logging schemes to achieve IP tracking. Others combine packet marking with packet logging and therefore create hybrid IP trace back schemes demanding less storage but requiring a longer search. In this paper, we propose a new hybrid IP trace back scheme with efficient packet logging aiming to have a fixed storage requirement for each router in packet logging without the need to refresh the logged tracking information and to achieve zero false positive and false negative rates in attack-path reconstruction. http://ijaems.com/detail/a-novel-ip-traceback-scheme-for-spoofing-attack/ Dr K Butchi Raju http://ijaems.com/upload_images/issue_files/1 IJAEMS-FEB-2017-3-A Novel IP Traceback Scheme for Spoofing Attack.pdf Digital multipliers are among the most critical arithmetic functional units. The overall performance of these systems depends on the throughput of the multiplier. Meanwhile, the negative bias temperature instability effect occurs when a pMOS transistor is under negative bias (Vgs = −Vdd), increasing the threshold voltage of the pMOS transistor, and reducing multiplier speed. A similar phenomenon, positive bias temperature instability, occurs when an nMOS transistor is under positive bias. Both effects degrade transistor speed, and in the long term, the system may fail due to timing violations. Therefore, it is important to design reliable high performance multipliers. In this paper, we propose an aging-aware multiplier design with novel adaptive hold logic (AHL) circuit. The multiplier is able to provide higher throughput through the variable latency and can adjust the AHL circuit to mitigate performance degradation that is due to the aging effect. Moreover, the proposed architecture can be applied to a column- or row-bypassing multiplier. The experimental results show that our proposed architecture with 16 ×16 and 32 ×32 column-bypassing multipliers can attain up to 62.88% and 76.28% performance improvement, respectively, compared with 16×16 and 32×32 fixed-latency column-bypassing multipliers. Furthermore, our proposed architecture with 16 × 16 and 32 × 32 row-bypassing multipliers can achieve up to 80.17% and 69.40% performance improvement as compared with 16×16 and 32 × 32 fixed-latency row-bypassing multipliers. http://ijaems.com/detail/age-acknowledging-reliable-multiplier-design-with-adaptive-hold-logic/ Dontabhaktuni Jayakumar, Ch Ananda Kumar, B.

The main objective of this work is to discuss the impact of biodiesel from Pomegranate fruit seed oil bio-diesel on performance, combustion and emission characteristics diesel. In this study, the effect of bio-diesel from fruit seed oil [Indian Pomegranate seed oil] and its blends on a single cylinder Kirloskar TV-1 diesel engine were investigated. In this work, the performance, combustion and emission analysis were conducted. The tests were performed at steady state conditions with the blend ratio of B25, B50, B75 and B100. These represent the ratio of biodiesel in the blend and the rest diesel. The aim of this investigation was to reformulate the fuel to utilize the biodiesel and its blend to enhance the fuels performance, combustion characteristic and to reduce the pollution from the engine. In this work only Indian Jujube seed oil bio-diesel is utilized for the experimental work. The experimental results reveal a marginal decrease in brake thermal efficiency when compared to that of sole fuel. In this investigation, the emission test were done with the help of AVL DI gas analyzer, in which CO, HC and NOx are appreciably reduced on the other hand smoke, CO2 have marginal increased when compared to that of sole fuel. In this work combustion analysis also made with the help of AVL combustion analyzer in which bio diesel blend shows the better result when compared with diesel. http://ijaems.com/detail/performance-and-emission-radiation-using-of-indian-pomegranate-seed-oil-as-bio-diesel/ G.V.Churchill, C.Ananda Srinivasan http://ijaems.com/upload_images/issue_files/3 IJAEMS-JAN-2017-34-Performance and Emission Radiation using of Indian.pdf Quantity Surveyors are an asset to both the building clients and other professionals within and outside the construction industry. This is because quantity surveyors are in charge of financial matters and provide cost management expertise in the industry. Not fully knowing their roles as quantity surveyors have hindered their engagement by the public, especially non-construction professional. This research work was carried out with the Aim of appraising the perception of Quantity Surveying Profession by Non-allied construction professionals in Nigeria, with a view to determining the level of awareness on the existence and roles of the quantity surveyors in Nigeria. The study employed questionnaire survey. Mean item score and percentage were used to analyze the data collected. It was discovered that 94.6% of the respondents have heard about the Profession and majority of them are aware of the profession for over 5 years. The study concluded that the awareness level of quantity profession among the non-construction professionals is high although, they are not well patronized by the public due to the cost of hiring the professionals. Also, there were low level of awareness in few of quantity surveyors’ duties and roles. It is recommended that there is the need for the Professionals to work hard to improve their image so as to attract patronage. http://ijaems.com/detail/appraisal-of-the-perception-of-quantity-surveying-profession-by-non-allied-construction-professionals-in-nigeria/ Eze Emmanuel Chidiebere, Awodele Imoleayo Abraham, Seghosime Ramat http://ijaems.com/upload_images/issue_files/4 IJAEMS-FEB-2017-4-Appraisal of the Perception of Quantity Surveying Profession.pdf An investigation of a viscoelastic material damping effect is studied on an example of plenum air-cushion craft model.

However, membrane fouling is a critical problem associated with reverse osmosis (RO) plants, since it has many negative impacts on RO efficiency, effectiveness and operation costs. Moreover, membrane cleaning techniques used to overcome fouling reduce the membrane life time, and sometimes it damage the membrane, also these techniques may create environmental issues related to the waste chemical disposal. In this study the effectiveness of applying Kinetic Degradation Fluxion media (KDF ) as pretreatment step for reducing fouling caused by high dosage of chlorine in RO system was investigated. Each test was carried out using two membranes, reference or control membrane in which feed solution moved directly inside without passing through the KDF media (RO-only), and pretreatment membrane with feed solution passing through KDF media (RO-KDF). The comparison between the two systems in terms of salt rejection and permeate flow indicates that KDF-media effectiveness in cl2 removal is high and it can extend the lifetime of RO membrane 3 times at least. http://ijaems.com/detail/reverse-osmosis-membrane-chlorine-effects-reduction-using-kinetic-degradation-fluxion-media/ Rawan Abu Eisheh, Jawad A.

These large diameter pipes such as φ216.3 mm are used for a plant as a flow channel of gas and liquid. The connection of pipes are generally welded at the plant. However, the other connecting method are required from a viewpoint of making the plant environment worse by welding. Therefore, flaring process of large diameter pipes were proposed. This flaring process is one of a method of pipe flange forming. The formed pipes were connected used with loose flange. Flaring process was generally hot process, thus it has some problem such as becoming complex of forming machine and accuracy of dimension. In this study, cold flaring process of SGP pipe was proposed to satisfy these requisitions. FEM analysis of cold flaring process were performed to clarify the optimum forming conditions for the flat length of connecting surface such as corner R. As a result, the optimum die corner R was from R6 to R9. http://ijaems.com/detail/fem-analysis-of-cold-flaring-process-of-sgp-pipe/ Ryosuke Okushima, Shinichi Nishida, Junshi Ichikawa, Yuta Kashitani, Yujiro Nitta, Atsuhiro Aoki, Yuto Takigawa, Hayato Aso, Hideto Harada, Akihiro Watanabe http://ijaems.com/upload_images/issue_files/13 IJAEMS-FEB-2017-24-FEM Analysis of Cold Flaring Process of SGP Pipe.pdf Plastic forming of magnesium alloy is hardly reported because of its low forgeability. The productions of magnesium alloy are mainly produced by casting. Typical wrought magnesium alloy is AZ31. Magnesium-aluminum alloy indicates maximum elongation when the composition includes 3% aluminum. When the magnesium alloy includes over 3% aluminum, its elongation slightly decreases. Therefore, AZ31 that include 3% aluminum and 1% zinc is generally used for plastic forming. The more increasing aluminum composition, the larger 0.2% proof stress becomes. However its forgeability is decreasing because of precipitation of β phase such as Mg17Al12. It is supposed that the β phase is refined by rapid cooling casting process such as twin roll casting. In this paper, the magnesium alloy thick sheet of AZ91, AZ121 and AZ131 for hot forging, that include 9%, 12% and 13% aluminum composition respectively, was produced by twin roll strip casting process. And the forgeability of high aluminum containing magnesium alloy was investigated by die forging. As a result, it was possible to forge their magnesium alloys. http://ijaems.com/detail/forgeability-of-az-series-magnesium-alloy-produced-by-twin-roll-casting/ Nao Ozawa, Shinichi Nishida, Toshio Haga, Junshi Ichikawa, Yuta Kashitani, Ryosuke Okushima, Yujiro Nitta, Atsuhiro Aoki, Yuto Takigawa, Hayato Aso, Hideto Harada, Akihiro Watanabe http://ijaems.com/upload_images/issue_files/14 IJAEMS-FEB-2017-25-Forgeability of AZ Series Magnesium Alloy produced by Twin Roll Casting.pdf Image morphing provides the tool to generate the flexible and powerful visual effect.

The growth of pearl oysters are affected by the availability of food (phytoplankton) in the waters. The phytoplankton own self is highly affected by N and P in the waters. This study aims to assess the carrying capacity of the Sathean Bay for pearl oysters farming for three different size group pearl oyster based on the nutrient balance which was the ratio between N and P are available in the waters and in the pearl oyster tissue. The study was conducted from April to September 2016 in nine sampling sites of Sathean Bay, Southeast Maluku. The result showed the smallest group size of pearl oyster(5 ± 2 cm) had the highest carrying capacity among the other two size group (13 ± 2 cm, 18 ± 2 cm). The carrying capacity of pearl oyster based nitrogen level(DIN) in the waters was always greater than the carrying capacity based on DIP level for all size groups of pearl oyster. http://ijaems.com/detail/carrying-capacity-for-pinctada-maxima-jameson-1901-farming-in-sathean-bay-southeast-maluku-based-on-nitrogen-and-phosphate-balance/ Usman Madubun, Ario Damar, Kadarwan Soewardi, Niken Tunjung Murti Pratiwi http://ijaems.com/upload_images/issue_files/16 IJAEMS-FEB-2017-14-Carrying Capacity for Pinctada maxima (Jameson 1901) Farming in Sathean Bay.pdf The globalised world has become more integrated and has witnessed an unprecedented dispersal of Multinational Enterprises (MNEs) across various nations and regions of the world. Most of these MNEs advertently or inadvertently exhibit tendencies that show them off as ethnocentric- possessing superior culture than those of their host country. This study assessed the effects of ethnocentric behaviours on the performance of MNEs in the South West of Nigeria. Adopting a survey design, the study made use of primary data collected mainly through administering a set of questionnaire to 207 management staff of selected MNEs from Oyo, Lagos and Ogun states respectively. Findings inter alia revealed that: engaging expatriates in strategic positions by MNE’s leads to increased operating costs; foreign culture of MNE’s home country negatively affects the local acceptance of management techniques by employees in host countries and MNE’s standardized marketing strategies encouraged customers’ loyalty and patronage in the Nigeria business environments. The work among other things, recommends that local employees in host nations must be incorporated into key decisions to aid MNE’s continuous effectiveness. The work, in addition to that, also advised that MNE’s should guide against culture shock i.e. the disorientation, cultural risks and stress associated with being in a foreign environment. http://ijaems.com/detail/ethnocentric-behaviour-and-business-performance-of-multinational-enterprises-mnes-evidence-from-south-west-nigeria/ Vincent A.

In this design, the triangular-shaped (inverted Y) three-electrode system consists of two stainless steel rods as the working and counter electrodes, and a brass rod as the pseudo-reference electrode inside the H2-air flame. The inter-electrode distance was set to 2.0 mm using two micrometers, connected to the counter and reference electrodes. The atomic emission of metal species such as alkali and alkaline earth ions was selected as the detection system during applying a fixed DC potential to the electrode system. In this system, the analyte was introduced into the flame as the electrolyte via formation of aerosols using a sonicator through the flow of N2 as a carrier gas. The mixture of H2 and air was introduced into the flame by a capillary hole along the working electrode. To analyze each metal ion, parameters such as type and quantity of supporting electrolyte, kind of electrodes, inter-electrode distance, applied potential, and the flow rates of H2, air, N2-were optimized using the one-at-a-time method. According to the figures of merit under the optimized condition, this system has linear dynamic ranges of 0.3-8.0, 0.26-9.6, 0.65-8.0, 64.0-192.0, 80.0-400.0, and 160.0-800.0 µg mL-1 for Li+, Na+, K+, Cs+, Ca2+, and Ba2+, respectively. Regarding 90% of maximum response (t90), the response time was estimated to be 7.0 s. The reliability of the sensor was also evaluated via determination of sodium and potassium in different wastewater samples. Compared to the flame photometry, no significant interfering effect was observed during spiking at least 200-fold excess of some foreign species such as alkali and alkaline earth metal ions to their standard solutions. An appropriate correlation was evaluated during the comparison between the results of this method and those estimated using inductively coupled plasma revealing the reliability and acceptance of this process. The validity of this method has also been evaluated via estimation of the recovery percentages. Compared to the atomic absorption/emission flame spectrometric techniques, the significant advantages of this AESE system include: I) more sensitive emission during applying the electrical potential in a cool flame such as H2-air; II) more improved detection limit and wider linear dynamic range, and III) the cheapness of this method. http://ijaems.com/detail/atomic-emission-spectroelectrochemistryas-a-sensitive-technique-for-trace-and-ultra-trace-determination-of-metal-species/ Mohammad Mahdi Doroodmand, FatemehGhasemi http://ijaems.com/upload_images/issue_files/21 IJAEMS-JAN-2017-19-Atomic Emission Spectroelectrochemistryas A Sensitive Technique.pdf Gas turbines are extensively used for air craft propulsion, land based power generation and industrial applications. Thermal efficiency of gas turbine can be improved by increasing turbine rotor inlet temperature. The current rotor inlet temperature in advanced gas turbine is for above the melting point of blade material. A sophisticated cooling scheme must be developed for continuous safe operation of gas turbines with high performance. Gas turbines are cooled externally and internally. Several methods have been suggested for the cooling of blades and vanes. The technique that describes in thesis is by cooling the blade by circulating sodium liquid filled inside it. The hot less denser sodium liquid travels the bottom region of the blade and transfer heat to the high velocity air passing near it. In this thesis a turbine blade model is designed and modeled in CATIA V5. CFD analysis of the model is performed for variant models.
