Investigating the Normal Operating Mode of Abule-Egba Distribution Grid with Respect to Bus Voltages, Line Currents and Line Flow[ ]


This paper carries out the power flow studies of the distribution network of Abule-Egba regional area using the Run Load-Flow Functionality (RLFF) of the ETAP software developed algorithm. The part of real network of Abule-Egba distribution network was modeled and simulated through load- flow analysis. This work generates report on the load-flow and the real and reactive power loadings of each transformer unit of the network. This report was analyzed using simulation by the plotting of graph imported into Matlab software environment. The result obtained for the bus voltage and current level, transformer rating and load distribution efficiency based on voltage and current variations under the existing normal operational mode were compared and analyzed with the reaction of surrounding network under abnormal condition when a three-phase fault system is simulated. By comparing these results (as shown in table 1), the reaction of the electrical system of Abule-Egba to three-phase fault at the various feeders can be predicted

Network Intrusion Detection Using Temporal Association Rules[ ]


Network security has become the most challenging issue in computer network field. Many researches have been done in detection of network intrusion in different layers of computer network. Most of the transport and network layer intrusion detection is based on previously specified signatures of packet fields without checking the relationship of one packet information with others. But these signatures cannot find novel attacks. Anomaly detection is used to find any behavior deviation from normal behavior. By using anomaly detection along with signature detection strength of IDS can be increased. This paper proposes an idea of mining temporal association rules between packet patterns of normal traffic. This method is making use of the temporal association of one packet pattern with the sequence of previous packet patterns to generate rules. These rules can detect any deviation from the normal activity as well as signature based intrusion. For optimization of rules a Reduced FP (False Positive) rate method is used. This method enables pruning the rules based on FP rate. Finally after several iterations a system with a reduced optimal FP rate will be obtained. Reduced error rate should be optimal so that number of detections is not much affected.

Design and Prototype Modelling Of Foreign Object Debris Detector and Remover[ ]


FOD interference for an aircraft in runway would cause damage. In severe cases, “Foreign Object Debris” can directly threaten safety of flight crews and integrity of the aircraft. Anything that can find its way into an aircraft engine or flight control mechanisms is a recipe for foreign object debris. So, Innovative future in airport can be reached here we implement the idea of FOD detection and removal in the airport runway into the concept that we designed a vehicle that can be radio controlled which will consist of Radar and a camera that will be used for detection, and Magnets with vacuum cleaner for removal of the detected debris. We consider different airports and their physical characteristics for implementing this concept. Our undertaking holds the imaginative engineering by more reliable by uses our vehicle in the service line in the airside and detect the FOD in Runway. This extend additionally includes the few numbers of vehicles, situated in an extra constructed area connected to the runway. Situated areas are constructed as per the calculations using the standard Runway length and time gap. Process will continue for each time gap. This vehicle would surely help to aircraft safety and do not need to hold it. The highlight of our concept is the mobility and the freedom that one gets in controlling and detecting the FODs.

Structural and Dielectric Properties of PZT Ceramics Prepared by Solid-state Reaction Route[ ]


Polycrystalline Pb (Zr1-xTix)O3 with x = 0.50 abbreviated as PZT has been prepared by high energy solid-state reaction technique. Analysis of XRD patterns of this composition suggests the formation of PZT phase with tetragonal structure. SEM studies were used for microstructural characterization. The dielectric properties of PZT ceramics have been characterized. The measurements have been made in frequency ranging from 100 Hz to 1 MHz and between room temperature (RT) and 550ºC for low and high frequencies. At RT, the value of dielectric constant (er) is 515.492 at 1 KHz whereas the loss tangent is 0.005. From er (T) measurements, the Curie temperature of our sample has been determined at 380ºC. The increase of er observed at high temperatures and low frequencies in the paraelectric state are explained, this abnormal behavior is due to the migration of oxygen ions towards the electrodes.

Asphalt – Polymer Blends: Leverage of Chlorine Gas on the Topography, Thermal Stability and Fuel Resistance[ ]


This paper evaluates the fuel resistance and the morphology of the asphalt physio-chemically modified using waste polymer namely high density polyethylene and chlorine gas. Different percentages (2%, 4%, 6% and 8%) of the waste polymer were used in the preparation of the asphalt blends followed by chlorination. Modified standard procedure was used to examine the solubility of asphalt blends in leaded petroleum kerosene while the morphology of the asphalt blends was characterized using optical microscope and the topography of these blends was computed by the aid of software. The obtained results showed that chlorination significantly reduces the asphalt solubility in the kerosene. It was also found that the new topographic method applied to identify the asphaltic blends further and to determine the homogeneity were clearly effective. The thermal stability has been improved for all samples. The dynamic shear rheometer outlined significant improvement in the viscoelasticity as well as the stiffness of the modified samples in compare to the original binder. Observing absorption band at 668 cm-1 in the Fourier Transform Infra-Red spectroscopy disclosed that the chlorine was introduced to asphalt binder matrix chemically meaning no phase separation may expect; in one word the modified samples tend to be more stable.

Mystery of Ramanujan Number: a3 + b3 = c3 + d3[ ]


1729 is the least number which can be expressed as sum of two cubes in two different ways. It was first identified by the great mathematician Sri Srinivasa Ramanujan in 1913. In my solution of Beal Equation mystery which was published in August Edition 2013 in IJSER, 4th volume, it was clearly shown that there cannot exist any number which can be expressed as sum of two numbers both are in power form of equal even exponents greater than two in two or more ways. So among all odd exponents three is the minimum. Why 1729 is the least? What should be the characteristic of a number to produce such type of relation? This paper basically contains the characteristic of a number with respect to its factors so that it can produce such type of Ramanujan relation.
