Leak Detection Modeling and Simulation for Oil Pipeline with Artificial Intelligence Method
Pudjo Sukarno,Kuntjoro Adji Sidarto,Amoranto Trisnobudi,Delint Ira Setyoadi
ITB Journal of Engineering Science , 2007,
Abstract: Leak detection is always interesting research topic, where leak location and leak rate are two pipeline leaking parameters that should be determined accurately to overcome pipe leaking problems. In this research those two parameters are investigated by developing transmission pipeline model and the leak detection model which is developed using Artificial Neural Network. The mathematical approach needs actual leak data to train the leak detection model, however such data could not be obtained from oil fields. Therefore, for training purposes hypothetical data are developed using the transmission pipeline model, by applying various physical configuration of pipeline and applying oil properties correlations to estimate the value of oil density and viscosity. The various leak locations and leak rates are also represented in this model. The prediction of those two leak parameters will be completed until the total error is less than certain value of tolerance, or until iterations level is reached. To recognize the pattern, forward procedure is conducted. The application of this approach produces conclusion that for certain pipeline network configuration, the higher number of iterations will produce accurate result. The number of iterations depend on the leakage rate, the smaller leakage rate, the higher number of iterations are required. The accuracy of this approach is clearly determined by the quality of training data. Therefore, in the preparation of training data the results of pressure drop calculations should be validated by the real measurement of pressure drop along the pipeline. For the accuracy purposes, there are possibility to change the pressure drop and fluid properties correlations, to get the better results. The results of this research are expected to give real contribution for giving an early detection of oil-spill in oil fields.
Long-Term Projections of Global Food Requirements: Why Were We Wrong?  [PDF]
Ira Sohn
Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.42026

This article reports on and analyzes long-term projections of world food requirements compared with observed 2000 data reported by the United Nations’ Food and Agriculture Organization. The importance of this “post-mortem” is to strengthen the case for carrying out long-term projections of essential resources—food, energy, and non-fuel minerals because of the long-lead times needed to insure that adequate global output levels of these basic ingredients of living standards will be met. This study should prove useful to those preparing today’s long-term projections, with world population projected to rise to over 9bn by mid-century.

Shah, Ira;
Brazilian Journal of Infectious Diseases , 2006, DOI: 10.1590/S1413-86702006000600011
Abstract: hiv-associated nephropathy has been found in children with hiv-1 infection as a late manifestation of this disease; it is associated with nephrotic syndrome with focal segmental glomerulosclerosis and/or mesangial hyperplasia with microcystic tubular dilatation. this is quite rare in children and no cases have been reported from india. several mechanisms have been hypothesized for the hiv-induced renal damage. we report on two hiv-infected children with hiv-associated proteinuria and dramatic response to antiretroviral therapy.

Abstract: In this short essay we would like to trace the main phases through which an educational research is developed in order to reflect on some important questions for the researcher during a survey. In the last decades the national and international debate on this topic has been very heated and complex; this work doesn’t pretend to be exhaustive but it aims at delineating the most significant moment characterising a survey path and at underlining the value of researching in education as praxis – of though and action – demanding to be theoretically founded, on one side, and methodologically rigorous, on the other side. In this essay the quantitative approach will be privileged to highlight its peculiarities and importance in educational research; nevertheless this approach will be critically analysed and discussed in the light of the most recent reflections on the paradigms for social sciences research and the possibilities and limits of theoretical and methodological integration between quantitative and qualitative approaches. In questo breve saggio, si vogliono ripercorrere le fasi principali attraverso le quali si sviluppa un percorso di ricerca empirica e sperimentale in educazione, allo scopo di riflettere su alcune questioni importanti che si propongono al ricercatore durante il suo lavoro di indagine. Negli ultimi decenni, il dibattito nazionale e internazionale a questo proposito è stato molto vivace e complesso; la presente trattazione non pretende dunque di essere in alcun modo esaustiva, bensì mira a delineare i momenti più significativi che caratterizzano un itinerario di indagine e a sottolineare il valore del fare ricerca in educazione quale prassi – di pensiero e di azione – che esige di essere, da un lato, teoricamente fondata e, dall’altro lato, metodologicamente rigorosa. Nel saggio verrà prediletto l’approccio più propriamente sperimentale e quantitativo, al fine di evidenziarne le peculiarità e le valenze nell’ambito della ricerca empirica in pedagogia; tale approccio sarà tuttavia analizzato e discusso criticamente alla luce delle più recenti riflessioni sui paradigmi teorici della ricerca nelle scienze sociali e sulle possibilità e i limiti dell’integrazione, teorica e metodologica, tra approcci quantitativo e qualitativo.
Text Messages: A potentially rich medium in distributed organisations
Ira Galushkin
PRism Online PR Journal , 2003,
Abstract: This article argues that SMS (or text messaging), a type of computer-mediated communication (CMC), can be regarded as a rich medium in distributed organisations. Theories such as media richness and social presence regard any CMC as a lean medium. However, as a result of technological advancements, these classic communication theories have become outdated. This article uses four other theories to argue against these traditional theories and suggest that organisational communicators need to consider text messaging as a rich medium in many circumstances. Social presence theory, social influence theory, social identity de-individuation theory, and the social information processing model consider additional factors such as context, time, management support, individual user attributes, and the task at hand, in assessing media richness. This article discusses further review of management support, the equivocality of the task, and the ability of SMS to aid egalitarian participation within an organisation, concluding that SMS does not replace face-to-face communication, but can be used with other traditional and non-traditional mediums within a distributed working context.

Abstract: This research is based on the phenomena of the existence of Banjarese traditional houses in Bakumpai tribe. This research compares 15 samples of traditional houses in Marabahan with 62 traditional houses in Banjarmasin. Based on the field observation, there are 5 types of traditional houses that look alike in both places. The five traditional houses are among the 11 types of Banjarese traditional houses, they are (1) Bubungan Tinggi type, (2) Balai Bini type, (3) Palimasan type, (4) Cacak Burung type, and (5) Joglo type. Based on the comparison analysis, it is concluded that there is a close relationship between the two places, Marabahan and Banjarmasin. This is shown by the similarity in space organization, the shape of the roof, name of the space, the function of the space, the structure and construction of the house, as well as the ornament applications. Nevertheless, there are some differences between the two places. The differences lie in the aspects of dimension and the motifs of carvings. While as traced through its history aspect, it is shown that the development of traditional architecture of Bakumpai tribe preceded the development of traditional architecture of Banjarese tribe. Abstract in Bahasa Indonesia: Penelitian ini didasari fenomena adanya rumah tradisional suku Banjar di wilayah kediaman suku Bakumpai. Penelitian ini membandingkan antara 15 sampel rumah tradisional di wilayah Kota Marabahan dan 62 rumah tradisional di wilayah Kota Banjarmasin. Dari hasil pengamatan lapangan, diperoleh hasil bahwa terdapat 5 (lima) tipe rumah tradisional yang sama di kedua wilayah. Ke-5 tipe rumah tradisioanl tersebut merujuk pada referensi 11 (sebelas) tipe rumah tradisional yang ada di wilayah suku Banjar. Lima tipe rumah tersebut adalah (1) tipe Bubungan Tinggi, (2) tipe Balai Bini, (3) tipe Palimasan, (4) tipe Cacak Burung, dan (5) tipe Joglo. Berdasar analisis perbandingan diperoleh kesimpulan bahwa terdapat hubungan yang sangat erat antar kedua wilayah. Hubungan tersebut ditunjukan oleh kesamaan organisasi ruang, bentuk atap, nama ruang, fungsi ruang, struktur dan kontruksi, serta adanya ornamen. Namun demikian perbedaan tetap ada, yaitu pada aspek dimensi dan ragam hias.motif ukiran. Sedangkan dari aspek kesejarahan, bukti catatan sejarah menjelaskan bahwa perkembangan arsitektur tradisional suku Bakumpai berkembang mendahului perkembangan arsitektur tradisional suku Banjar. Kata kunci: Suku Banjar, Suku Bakumpai, Hubungan Arsitektural dan Sejarah.

Indian Streams Research Journal , 2013,
Abstract: Reduction of infant mortality rate has been recognised as important goal in the Millennium Development Goals of United Nations Organisation. Assam in north eastern region of India has also experienced high rate of infant mortality in rural areas. Therefore, the paper attempts to highlight the problem of high rate of infant mortality in Assam. The study attempts to examine the trend of infant mortality in rural Assam in comparison with rural India. As adopting policies for reduction of this disparity depends crucially on identification of factors, therefore, the paper also put an endeavour to identify the factors behind the high infant mortality rate in rural Assam. The results show that improvement in health facilities in the state is slow in comparison with the country average. Monthly Per capita Consumer Expenditure, Literacy Rate, and Female Work Participation Rate are the significant factors in influencing infant Mortality Rate in rural Assam.

JK Science : Journal of Medical Education & Research , 2004,
Abstract: To determine the sensitivity and specificity of HIV DNA PCR (Qualitative) at various age groups todetect or rule out HIV infection in infants born to HIV infected mothers. Pediatric and perinatal HIVclinic in a tertiary pediatric hospital.Sixteen infants born to HIV positive mother enrolled in the preventionof mother to child transmission of HIV at our center were tested for HIV infection by HIV DNAPCR at 1.5 months, 3 months, 5.5 months and/or 7 months of age. Their HIV status was confirmedby an HIV ELISA test at 18 months of age by 2 different ELISA kits. Eight patients (50%) had anegative HIV DNA PCR whereas 8 patients (50%) had a positive DNA PCR of which 6 patients(75%) had a false positive HIV DNA PCR and no false negative DNA PCR. Thus, the sensitivity ofHIV DNA PCR was 100% and specificity was 57.1% with a total efficiency of the test being62.5%. The efficiency of HIV DNA PCR at 1.5 months of age was 50%, at 3 months of age42.9%, at 5.5 months of age 60% and at 7 months of age was 100%. HIV DNA PCR has a highsensitivity but low specificity to diagnose HIV infection in infants less than 7 months of age. Hence,the results of the test have to be interpreted with caution in infants born to HIV positive mothers.
