    In aerial photogrammetry, aerial photographs are acquired using aerial camera and light aircraft as a platform. The aerial photographs are usually processed for mapping such as for production of topographic map and other special purpose map known as thematic map. However, this method is expensive and suitable for large area but it is not practical for mapping small area. This study concentrates on the use of high resolution digital camera and a very light platform known as unmanned aerial vehicle (UAV) as data acquisition system in capturing digital aerial photographs. The acquired digital aerial photographs were processed using image processing software to produce digital map and digital orthophoto. The results showed that an accuracy of sub-meter can be obtained using the employed method. In Geographical Information System (GIS), it is quite common that topographic map and orthophoto are used as a base map. Hence, the findings from this study could also be used as an input for GIS. Not to forget, the photogrammetric technique could be used not only for mapping but it could also be used for any environmental protection and conservation

    Seasonal and extreme poverty in Bangladesh : evaluating an ultra-poor microfinance project

    Get PDF
    Microfinance is often criticized for not adequately addressing seasonality and hard-core poverty. In Bangladesh, a program known as PRIME was introduced in 2006 to address both concerns. Unlike regular microfinance, PRIME introduces a microfinance scheme that offers a flexible repayment schedule and consumption smoothing, as well as production, loans. It targets the ultra-poor, many of whom are also seasonally poor, with a severe inability to smooth consumption during certain months of the year. Besides providing loans, PRIME offers extension and training services. This paper uses a quasi-experimental survey design to evaluate PRIME against regular microfinance programs. The results show that PRIME is more effective than regular microfinance in reaching the ultra-poor, as well as the seasonal poor. PRIME also helps reduce seasonal deprivation and extreme poverty. Although the program has demonstrated its promise, it is too early to conclude whether the accrued benefits are large enough to contain both seasonal and chronic poverty on a sustained basis.Rural Poverty Reduction,Regional Economic Development,Food&Beverage Industry,Debt Markets

    Can social safety nets alleviate seasonal deprivation ? evidence from northwest Bangladesh

    Get PDF
    This paper examines the role of social safety-net programs in Bangladesh run by the government and nongovernmental organizations to mitigate seasonal deprivation in the country's highly vulnerable northwest region. Specifically, the paper explores whether social safety nets are limited to averting seasonal deprivation or can also address seasonality of income and employment more generally. Using a recent survey from the greater Rangpur (northwest) region, the paper finds that social safety nets have a positive effect on mitigating both seasonal and non-seasonal food deprivation. The results are robust, owing to the recent expanded coverage of social safety-net programs run by nongovernmental organizations active in the region. But given the annual recurrence of monga (seasonal food insecurity) in the northwest region owing to agricultural seasonality and an overwhelming dependence on agriculture for livelihoods, social safety nets are not a reliable tool for monga eradication. Programs are also needed to promote the income and productivity of the poor through diversification of income and employment.Safety Nets and Transfers,Rural Poverty Reduction,Food&Beverage Industry,Regional Economic Development,Housing&Human Habitats

    Jenis penelitian ini adalah eksperimen semu (Quasi Experiment) untuk mengetahui perbedaan hasil belajar siswa dengan menggunakan model pembelajaran kooperatif tipe STAD dan model pembelajaran berbasis masalah serta kecerdasan emosional siswa pada SMP Negeri berakreditasi A dan berakreditasi B. Populasi dalam penelitian ini adalah Siswa kelas VIII SMP Negeri di Kabupaten Gowa tahun pelajaran 2014/2015. Penentuan sampel penelitian dilakukan dengan menggunakan metode cluster random sampling. Sampel yang terpilih adalah empat kelas yang dipilih dari dua Sekolah Negeri yang ada di Kabupaten Gowa, yakni SMP Negeri 2 Sungguminasa dalam hal ini berakreditasi A dan SMP Negeri 4 Sungguminasa dalam hal ini berakreditasi B. Ada dua macam variabel dalam penelitian ini, yaitu (1) variabel bebas yang terdiri atas model pembelajaran, akreditasi sekolah dan kecerdasan emosional, dan (2) variabel terikat adalah hasil belajar matematika siswa. Model pembelajaran yang dimaksud dalam penelitian ini adalah model pembelajaran kooperatif tipe STAD dan model pembelajaran berbasis masalah, akreditasi sekolah yang dimaksud adalah akreditasi sekolah A dan akreditasi sekolah B, sedangkan kecerdasan emosional yang dimaksud adalah kecerdasan emosional optimal dan kecerdasan emosional rentan. Instrumen yang digunakan  adalah angket kecerdasan emosional, dan tes hasil belajar matematika. Hasil penelitian menunjukkan bahwa  (1) skor rata-rata hasil belajar siswa di sekolah akreditasi A dan akreditasi B cenderung sama, (2) kecerdasan emosional siswa di sekolah akreditasi A mempunyai skor rata-rata yang cenderung sama pada sekolah akreditasi B berada pada kategori optimal, (3) tidak terdapat pengaruh akreditasi sekolah terhadap hasil belajar siswa, (4) terdapat pengaruh model pembelajaran terhadap hasil belajar siswa, (5) terdapat pengaruh kecerdasan emosional terhadap hasil belajar siswa, (6) tidak terdapat interaksi antara akreditasi sekolah dan model pembelajaran terhadap hasil belajar siswa, (7) tidak terdapat interaksi antara akreditasi sekolah dan kecerdasan emosional terhadap hasil belajar siswa, (8) terdapat pengaruh interaksi antara model pembelajaran dan kecerdasan emosional terhadap hasil belajar siswa kelas VIII SMP Negeri di Kabupaten Gowa

    Dufour and Soret Effects on Unsteady MHD Free Convection and Mass Transfer Flow past a Vertical Porous Plate in a Porous Medium

    The Dufour and Soret effects on unsteady MHD free convection and mass transfer flow past an infinite vertical porous plate embedded in a porous medium have been studied numerically. The non-linear partial differential equations, governing the problem under consideration, have been transformed by a similarity transformation into a system of ordinary differential equations, which is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with sixth order Runge-Kutta integration scheme. The effects of various parameters entering into the problem have been examined on the flow field for a hydrogen-air mixture as a non-chemical reacting fluid pair. Finally, the numerical values of local Nusselt number and local Sherwood number are also presented in tabular form

    The problem of combined free-forced convection and mass transfer flow over a vertical porous flat plate, in presence of heat generation and thermaldiffusion, is studied numerically. The non-linear partial differential equations and their boundary conditions, describing the problem under consideration, are transformed into a system of ordinary differential equations by using usual similarity transformations. This system is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. The effects of suction parameter, heat generation parameter and Soret number are examined on the flow field of a hydrogen-air mixture as a non-chemical reacting fluid pair. The analysis of the obtained results showed that the flow field is significantly influenced by these parameters
