FAST AND PARALLEL MINING OF K HIGH UTILITY ITEMSET[ ]


A large number of contributions in the literature have been proposed for item set mining, exploring various measures according to the chosen relevance criteria. However, items are actually different in many aspects in a number of real applications, such as retail marketing, network log, etc. The difference between items makes a strong impact on the decision making in these applications. Therefore, traditional ARM cannot meet the demands arising from these applications. By considering the different values of individual items as utilities, parallel mining focuses on identifying the itemsets with high utilities.

Requirements Prioritization Using Analytic Network Process (ANP)[ ]


Software project development deals with many requirements. Since software is developed in different increments, it is difficult for requirement engineers to implement all these requirements in one single increment. For this purpose, prioritization of requirements is essential in order to deliver right product on right time. A thorough survey of literature depicts that no requirements prioritizing methodology prioritizes dependent requirements. Moreover, performance of existing methodologies regarding requirements prioritization needs improvement. During the literature survey, most of the prioritization methodologies were studied and critically reviewed. After analyzing different techniques, a new requirements prioritization methodology is proposed and a model is developed that can prioritize both dependent and independent requirements. The interdependent requirements will be prioritized with newly proposed requirements prioritization technique that is Analytic Network Process (ANP). The simulation results of the proposed technique showed that ANP produced finest outcomes for prioritizing requirements. The simulations were carried out in MATLAB software.

High Performance of Induction Motor Based on New DTC-SVM[ ]


Direct torque control (DTC) is one of the most important control techniques used in induction motor drives to obtain high-performance torque control and speed response. However, the classical DTC-SVM has disadvantage through transient, steady state and low speed. One of the most important defects is a high torque ripple and harmonics in stator current. In this paper,the proposed control system for solve these problems by utilizing space vector modulation upon the reference torque and flux (DTC-SVM). In this proposed control technique, PI flux and PI torque controller are designed to investigation estimated flux and torque with good tracking and fast response with reference torque and there is no steady state error. In addition, design PI flux and PI torque controller are utilized to improve voltage in d-q axis which applied to SVM. The DTC-SVM is applied to the three-phase three-level neutral point clamped diode inverter (NPC) which fed the induction motor drive. This paper confirms using the Space Vector Pulse Width Modulation (SVPWM) technique for derivation of switching states. The proposed control is implemented using MATLAB/Simulink software package. Resulting tests which obtain from the proposed control is better than the classical system.

Comparison of Signal to Noise Ratio of Lower Atmospheric Wind Profiler Data using Signal Processing Techniques[ ]


The main objective of the Lower Atmospheric Wind Profiler (LAWP) is used to identify the atmospheric echoes and estimation of the three spectral moments (i.e., zeroth moment, first moment and second moment) is most important for the study of dynamics and to provide continuous high resolution wind measurements in all weather conditions. The height profile of the wind vector can be improved by detecting the Doppler shift of echoes, so that Signal to Noise Ratio (SNR) may also be improved. At present, we are receiving the LAWP radar data at National Atmospheric Research Laboratory (NARL), Gadanki, India. SNR and doppler shift computation are important parameters in radar signal processing. This paper discusses improvement of doppler shift using Fast Fourier Transforms (FFT), Empirical Mode Decomposition (EMD) and Wavelet Transforms (WT) for LAWP signals. The threshold can detect the fake peaks that are adjacent to the actual signals. In order to get the actual position of the object, those fake peaks should be removed by using Peak Detection Algorithm. SNR for this LAWP data is computed for EMD and Wavelet de-noised signals are compared with the FFT de-noised signals. Results show that there is an effective doppler shift and 21 dB improvement in SNR after de-noising using Db11 wavelet for Lower Atmospheric signals.

Reclamation of Nanjarayan Lake by Using Bioclean STP Treatment Tirupur Corporation in Tamilnadu, India[ ]


The demand for water in and around Tirupur region is very high as the water bodies are very few in number even the available water bodies are being polluted by dying unit effluents and other harmful industrial effluents being let out into the available water source due to lack of waste disposal units. Nanjarayan Lake is a 440 acre reservoir in the outskirts of Tirupur town, near Koolipalayam, off Uthukkuli Road. It is officially known as “Koolipalayam Reservoir” or “Sarkar Periyapalayam Reservoir”. Going back in history, we come to know that this tank was built by a local king called “Nanjarayan”, over 400 years ago. Hence the tank has been renamed as Nanjarayan Tank in the recent past. This tank has been a home for several inland and migratory birds for centuries. The water source is the Nallar River, flowing from the Avinashi big Tank and few sewage canals, carrying the effluents and sewage from Tirupur town. Eventually the water level has never come down due to the above sources.The flora and fauna of this tank attracts as many as 135 species of birds from all over. Inland birds like Spot-billed Pelicans, Painted Storks, and etc. It also brings in a huge number of species from other parts of the World during the winter. Starting from November, every year, various birds flock in to Nanjarayan Tank and spend their winter and leave back to their home by the end of March. A new method called Bio-Ozolyte method has been implemented and tested by us to treat and restore the water in the reservoir. This method involves three treatments they are biological treatment, Ozone treatment and Anoyte treatment. This method increases the dissolved oxygen level in the water and makes the water favorable for existence of organisms and fit for usage. If this reservoir is restored, all water demands in and around Tirupur can be met.

Possibility of Dispensing Cycle Slips Correction Process Using Artificial Neural Networks (ANN)[ ]


Cycle slips may result in critical errors in the derived positions if it were not detected and treated properly. All previous works in this field concerned with detecting the occurrence of cycle slips, and hence, fixing the new value of the phase ambiguity. Then, the collected data should be re-processed to get the corrected 3-D coordinates. In this paper, a new approach was tried to dispense this traditional scenario. This approach is based on the modeling of the positional errors, resulted by cycle slips, using Artificial Neural Networks (ANN). The main reason behind the choice of ANN is its ability of relating different inputs and outputs without deciding previously the kind of relation (mathematical model) among them. The key for the successful construction of the thought ANN is the determination of the involved parameters that should be used as inputs.

Uses and quality assessment of cocoa butter sold in retail markets in Yaounde capital city, Cameroon[ ]


This study was carried out to screen the uses and evaluate the quality of cocoa butter sold in local markets. A survey was conducted in markets of Yaoundé capital city. Thirty cocoa butter users and twenty sellers were directly interviewed. In assessing the quality of cocoa butter, five samples were randomly purchase and their physicochemical composition compare to a control. Coliforms and mould were looked for to asses the sanitary quality of the samples. Analysis of data shows that the majority of cocoa butter users are young people between 25-30 years old. Cocoa butter is generally used in therapy and then in cosmetic and finally as food. The majority of users are satisfied after using cocoa butter but the quality of the product remains their expectation. Cocoa butter sellers are mainly famers. Cold processing is the extraction method. The result of physicochemical analysis shows that four of the five samples bought on markets are adulterated. For all samples, contamination by coliform is less than the standard limit. The presence of mould was detected in two of the five samples analyzed which can be attributed to an inadequate processing or a post processing contamination.

Sewage Sludge Management: A Case Study of Monrovia, Montserrado county Liberia[ ]


Sewage sludge management has been a problem faced by most developing cities as in the case of Monrovia. The management of sewage sludge in Monrovia is still in its infant stage. The city is still struggling with poor sanitation, clogged pipes, shortage of septic tanks, lack of resources/human capacity, inadequate treatment facilities, open defecation, absence of clear guidelines etc. The rapid urban population growth of Monrovia has severely stressed Monrovia’s marginally functional urban WSS system caused by the civil conflict which led to break down in many sectors as well as infrastructure. The sewerage system which originally covered 17% of the population of Monrovia was down to serving about 7% because of bursts and blockages causing back flows in other areas. Prior to the Civil War, the average water production for Monrovia was about 68,000 m3/day, but has now dropped to about 10,000 m3/day. Only small parts of Monrovia currently have direct access to the piped water supply while most areas depend on trucked water delivered to community collection points or household tanks, and/or on water from unprotected dug wells or hand pumps. There are only two functional treatment plants; The Fiamah Treatment plant and the White Plains Treatment Plant.

International Journal of publication[ ]


This abstract contemplate on literature as activism which promotes the writer to think critically how this literature made known to be as an activism through the writings of Toni Morrison. She is one of the outstanding writers who contributed much on African American Literature. Her contribution to literature is highly appreciated, brought out the changes in the socio-political issues. African Americans were discriminated against and subject to racist attitudes. It explores the issues of freedom and equality long denied to Blacks in the United States. They often tried to exercise their political and social autonomy in the face of resistance from the white public. Throughout American history, African American has been discriminated against and subject to racist attitudes. This experience inspired some black writers, like Toni Morrison at least during the early years of African American literature to prove that they were the equals of European- American authors. The core focus of black feminist writing was based on racism, sexism, heterosexism, and classism in their lives.

Application of Pareto principle and Fishbone diagram for Waste Management in a Powder Filling Process[ ]


This paper represents a detailed assessment on raw material waste generation of a semi-automated powder filling and packing process by applying certain quality tools such as Pareto Analysis and Fishbone Diagram. The aim of this study is to identify the sources or categories of raw material waste and analyse its underlying causes. Waste generation is an unavoidable incident in any production process which could even result in products with varied weights. The major waste source; “overfill” occurs when powder is filled more than the actual net weight resulting a loss in waste. Therefore identification of underlying causes for powder waste and a measure to minimize it, using monitoring and controlling is vital to maintain consistency of the product. In this paper, Pareto principle, a major statistical quality control tool is applied to identify the key sources of waste within the production line. In order to detect possible underlying reasons/factors, a fishbone diagram is applied.
