The Taguchi parameter design approach was used to find the optimal conditions for electrolytic Pb(II) removal using a flow-by fixed bed electrochemical cell composed of a vertical stack of stainless steel screens. The investigated process parameters were initial metal ion concentration, current, flow rate, and mesh number of screen. Removal, current efficiencies, and energy consumption were considered as responses for the optimization of metal removal. An orthogonal array L9, the signal-to-noise(S/N) ratio, and the analysis of variance were used to analyze the effect of selected process parameters and their levels on the performance of Pb(II) removal.The results indicated that concentration and current have the major effect on performance of lead removal. Flow rate and screen mesh number have lower contribution on the performance of Pb(II) removal and their contributions are close in all responses. The optimum values of control factors were Pb(II) initial concentration 200ppm, current 0.58A, flow rate 7l/min ,and mesh number 40 wire/in. The highest current and removal efficiencies were 48.5% and 89.7% respectively with energy consumption (2.43kwhkg-1).

Effects of Surcharge on the Behavior of Passive Piles in Sandy Soil[ ]


The effects of adjacent embankment on the behavior of pile in sandy soil, river sand, had been investigated through manufacturing an experimental model of steel. The soil sample classified as (SP-SM) according to USCS of dry unit weight 13.5 kN/m3. The pile model was an aluminum tube of 10 mm outer diameter. An incremental surcharge was applied at distances of 2.5D, 5D and 10D from the edge of pile model, where D is the outer diameter of model pile. Also, two embedded lengths were investigated Le = 360 mm which classified as rigid pile and Le = 420 mm which classified as flexible pile. The effects of these parameters had been studied on axially loaded pile (LP) and unloaded pile (UP). The results obtained from the model piles are: the displacement at the soil surface, the rotation at the soil surface, bending moment profiles, pile deflection profiles, pile rotation profiles, and shear force profiles. Some of these results are measured experimentally an others are calculated theoretically based on measured values.Based on the results of tests, it was concluded that increasing the distance between the embankment and pile reduces the effects of embankment on the pile, also the axial loading on pile reduces the effects of embankment on the pile.

STRATEGIC PLANNING FOR ENTERPRENUERSHIP STUDIES IN INDUSTRIAL DESIGN PROGRAMMES[ ]


Although Industrial Design Programmes constitute some of the curricular arrangements in Nigerian Institutions of higher learning for the purpose of establishing a strong foundation for entrepreneurship studies, there are strong indications of summountable problems. According to Blake (2011) there are problems of traditionalism and conservative beliefs which have largely failed to exploit the roles of effective communication in emphasizing the importance of the curricular underpinnings. Industrial Design Programmes being interdisciplinary and multidisciplinary studies with commitments linked to entrepreneurship must embrace the sense of innovations. These factors according to Onwuka (2010) are meant to explore and capitalize on the development and advantages of appropriate resources for the purpose of rationalizing instructions on entrepreneurship education in Industrial Design.

Ranked Phrase Search Using Order Preserving Encryption For Cloud Documents[ ]


Cloud Computing has been considered as the next-generation architecture of IT Enterprise. This exclusive paradigm produces many new security issues, which have not been well recognized. This paper presents a new framework for privacy preserving multikeyword rank-ordered search and retrieval over large document collections. The proposed framework not only protects document/query privacy against an outside intruder, but also prohibits an untrusted data center from learning information related to the query and the document collection. We introduce practical methods for proper combination of relevance scoring methods and cryptographic techniques, such as order preserving encryption, to protect data collections and indices and provide efficient and accurate search capabilities to securely rank-order documents in response to a query and related document collection. The proposed methods thus form the steps to bring together advanced information retrieval and secure search capabilities for a wide range of applications including managing data in government and business operations, enabling scholarly study of sensitive data, and facilitating the document discovery process in litigation.

Pros and cons of different types of geometry[ ]


Geometry must be as longstanding and deep rooted as humans’ fight for the sake of survival. Making a good hunting bow and the different kind of arrows having different shapes surely involved some special kind of intuitive gratitude of distance, space, direction, and kinematics. In the same way, delimitating the enclosures, constructing the shelters, and accommodating the little hierarchical or classless communities must have presumed an appreciation for the ideas, concepts and designs of center, length, equidistance,area, straightness and volume.Some of the above mentioned illusorily “clear” terminologies remain vague as human beings are not very well servedand aided all the time by different kinds ofmathematical acculturation that encompasses even one of the finest available instruction in fundamental geometry. Different shapes need different kind of rules to relate them with real world and different kind of geometry types are used for this purpose.

Initialize and extract M-dimensional vectors or blocks from that image. However, initialize and design a code-book of size N for the compression. Quantize that image by using K-Means Algorithm to design a decode with table-lookup for reconstructing compressed image of different 8 scenarios. Compute the histogram equalization, discrete fourier transform, and fourier spectrum for the original and reconstructed image. Hence, perform that image compression in spatial filtering domain to distinguish it with the frequency filtering domain. To get in more detailed and experimental purposes, how this compressed reconstructed image pass through low pass and high pass filter from different techniques (Ideal, Gaussian, and Butterworth) in frequency filtering domain. With the help of vector quantizing K-Means clustering algorithm, evaluate and analyze the performance metrics (compression ratio, bit-rate, PSNR, MSE and SNR) for reconstructed compress image with different scenarios depending on size of block and code-book. Once finally, check the execution time, how fast it computes that compressed image in one of the best scenarios. The main aim of Lossless Huffman coding using block and codebook size for image compression in spatial and frequency domain is to convert the image to a form better that is suited for analysis to human by using K-Means algorithm. In this research paper, performance metrics also notifies from scenario (figure 57(c), when M=16 and N-25, if threshold=0.1) to perform lesser entropy and higher the average length for lossless Huffman coding on image compression using K-Means Algorithm,. Finally, in this research paper that scenario 8 from figure 3, image has a higher PSNR, SNR and lesser Compression ratio shows a better quality of reconstructed image using K-Means algorithm in terms of Lossless Huffman coding in spatial and frequency domain.

Pronunciation Problems Arab Speakers Encounter While Learning English[ ]


Arabic is an official spoken and written language in 23 countries. Arabic is the most important language for 1.5 billion Muslims around the world because it is the language of The Quran, which is the book of Islam and the different are ways of using the language. Pronunciation in Arab countries varies due to the distances and cultural differences. In Morocco, Arab speakers use a certain pronunciation and accent that cannot be understood by Arab speakers in the Middle East, such as people from Saudi Arabia and Egypt. (Wahba, Taha, and England. 2006. Page 3). These differences might affect learners’ speaking and pronunciation such as using the plural s and stress. “The Arabic and English phonological system are very different, not only in the range of sounds used, but in the emphasis placed on vowels and consonant in expressing meaning (& Smith, 2001, page 195-196). These variations mean Arab speakers might encounter different problems pronouncing some vocabulary, but usually they encounter similar difficulties. In Arabic there are 28 letter which are easy to comprehend and be heard as sounds.
