    Modelling the intermixing effects in highly strained asymmetric InGaAs/GaAs quantum well

    In this work, we have theoretically investigated the intermixing effect in highly strained In0.3_{0.3}Ga0.7_{0.7}As/GaAs quantum well (QW) taking into consideration the composition profile change resulting from in-situ indium surface segregation. To study the impact of the segregation effects on the postgrowth intermixing, one dimensional steady state Schrodinger equation and Fick's second law of diffusion have been numerically solved by using the finite difference methods. The impact of the In/Ga interdiffusion on the QW emission energy is considered for different In segregation coefficients. Our results show that the intermixed QW emission energy is strongly dependent on the segregation effects. The interdiffusion enhanced energy shift is found to be considerably reduced for higher segregation coefficients. This work adds a considerable insight into the understanding and modelling of the effects of interdiffusion in semiconductor nanostructures.Comment: 6 pages, 4 figure

Dengan menggunakan metode yuridis empiris, penelitian menunjukkan bahwa: 1). Pelaksanan pidana pelatihan kerja di Balai Rehabilitasi Sosial Anak Memerlukan Perlindungan Khusus Alyatama Jambi dapat dikatakan belum terlaksana, Balai Rehabilitasi Sosial Anak Memerlukan Perlindungan Khusus Alyatama Jambi sebagai tempat pelaksanaan pelatihan kerja tersebut belum memberikan pelatihan kerja dikarenakan belum adanya Peraturan Pemerintah mengenai pelaksanaan pidana pelatihan kerja, sehingga Balai Rehabilitasi Sosial tersebut hanya memberikan Rehabilitasi berupa Terapi-terapi mulai dari terapi Psikososial hingga terapi mental dan spiritual 2). Kendala yang dihadapiyaitu dari Peraturan pelaksana yang belum ada, sarana dan prasaraan pendukung belum tersedia, serta belum adanya petugas yang secara khusus memberikan pelatihan kerja terhadap anak pelaku tindak pidana.

    Integration Efforts Estimation in Service Oriented Architecture (SOA) Applications

    Get PDF
    Service Oriented Architecture (SOA) is an emerging area of software engineering, based on the concept of re-usable services to support the development of rapid, economical and stable distributed application even in heterogeneous environments. Function point is considered an accurate and well established approach among its competitors to estimate the efforts, size and functionality of software development projects. Estimating the cost, size and efforts for SOA application is a difficult task due to its diverse nature and loose coupling behavior, which results in an inaccurate estimate to measure the efforts, size and functionality of SOA applications. This research paper highlights the integration efforts estimation using a work flow model, to accurately estimate the efforts and cost needed for SOA application. Keywords: Service Oriented Architecture (SOA), Integration Efforts, Efforts Estimation, Function Point Analysis
