Non-viscous Regularization of the Davey-Stewartson Equations: Analysis and Modulation Theory

In the present study we are interested in the Davey-Stewartson equations (DSE) that model packets of surface and capillary-gravity waves. We focus on the elliptic-elliptic case, for which it is known that DSE may develop a finite-time singularity. We propose three systems of non-viscous regularization to the DSE in variety of parameter regimes under which the finite blow-up of solutions to the DSE occurs. We establish the global well-posedness of the regularized systems for all initial data. The regularized systems, which are inspired by the $\alpha$-models of turbulence and therefore are called the $\alpha$-regularized DSE, are also viewed as unbounded, singularly perturbed DSE. Therefore, we also derive reduced systems of ordinary differential equations for the $\alpha$-regularized DSE by using the modulation theory to investigate the mechanism with which the proposed non-viscous regularization prevents the formation of the singularities in the regularized DSE. This is a follow-up of the work of Cao, Musslimani and Titi on the non-viscous $\alpha$-regularization of the nonlinear Schr\"odinger equation

Perancangan Monitoring Jarak Jauh Ketinggian Air pada Bendungan Menggunakan Sistem Android Via Jaringan Wi-fi

In this writing of this essay has discussed a problem about “DESIGN OF DISTANCEMONITORING IN DAM LEVEL USING ANDROID SYSTEM VIA WI-FI NETWORK”. Thistools used for remote monitoring from distance ofthe water level atthe dam using android. Soit can easer us to monitor the dam though from a great distance. Simulation of this dam usingAT89S51 Microcontroller, conductivity sensor, PSA, Relay, water pump system also Androidand PC as Server and Receiver when the tool works. conductivity sensor works read the leverof water and then sent to e server that can be monitored from great distance using android.This tools work when sensor detect the level of water then the microcontroller and sent thedata to the PC by RS232 and in the computer displayed visualization the lever of water andbroadcasted by wifi network.This program created to readthe level of water and detected bysensor. The data sent to the PC by serial port

Evaluasi Dampak Pembangunan Sosial, Bagi Kesejahteraan Masyarakat Kabupaten Purbalingga

This research evaluation is a part of activities development management is to know how the activities development works. Evaluation could be good or bad is depended on the inputs of the monitoring systems. This research is analysed by indicator descriptions. The conclusion shows that Purbalingga's PDRB in 2003 increase about 1.3%. In other side, the gaps among sectors are low enough. It means each sector works better and relatively will be spread evenly. That's why the policy of budget allocation is better to lead to have interrelatedness (backward and forward) for all sectors

Prospek Pembangunan Hutan Tanaman Rakyat di Kabupaten Biak Nunfor, Papua

Pembangunan hutan tanaman oleh rakyat diharapkan secara bertahap akan mengubah lahan kritis menjadi produktif dan meningkatkan kesejahteraan masyarakat. Salah satu faktor yang menyebabkan lambannya pembangunan hutan tanaman rakyat adalah kurangnya minat masyarakat. Untuk mendukung minat masyarakat dan pengusaha lokal dalam mengembangkan hutan tanaman rakyat dibutuhkan beberapa hal yaitu : sosialisasi program ditingkat masyarakat sehingga tepat sasaran, kepastian hukum atas status lahan, informasi kelayakan USAha baik secara teknis maupun finansialnya, dan pendampingan kelembagaan masyarakat. Penelitian ini bertujuan memberikan informasi prospek hutan tanaman rakyat yang dapat dikembangkan di Kabupaten Biak Nunfor termasuk manfaat ekonomis yang diterima dengan keberadaan hutan tanaman rakyat tersebut. Penelitian dilakukan dengan menggunakan metode Desktiptif Kwantitatif dengan teknik survey. Prospek pengembangan hutan rakyat dihitung dengan melihat aspek finansial dan kontribusi kegiatan HTR pada pendapatan petani. Perhitungan aspek finansial dilakukan dengan mengambil contoh pada hutan rakyat KTH Insumarires Distrik Biak Timur yaitu pendapatan bersih pengusahaan hutan dengan menggunakan rumus Faustman, kelayakan finansial dihitung kriteria Net Present Value (NPV), Benefit Cost Ratio (BCR) dan Internal Rate of Return (IRR) yang dinyatakan dalam satuan persen. Hasil penelitian menunjukkan 1) jika 10% dari hutan produksi di Kabupaten Biak Nunfor merupakan hutan produksi yang tidak produktif maka diperkirakan terdapat 7.477,8 ha yang dapat dimanfaatkan sebagai areal hutan tanaman rakyat dengan jenis unggulan Calophyllum inophyllum dengan menggunakan sistem silvikultur THPB. 2) Pengusahaan HTR layak dilaksanakan dalam daur 50 tahun dengan discount rate 5%. 3) Tingginya curahan hari kerja (5.724 HOK) memberikan dampak pada perluasan lapangan kerja dan tingkat pendapatan petani dari kegiatan tersebut. 4) Kontribusi pendapatan petani terbesar berasal dari nilai biodiesel dari biji Calophyllum inophyllum yang mencapai yang mencapai 68% dari total pendapatan. Perkiraan pendapatan bersih pengusahaan HTR yang dapat diterima pada akhir daur pengelolaan (50 tahun) oleh masing-masing anggota kelompok (1 kelompok 159 orang), dengan luas ideal pengusahaan ideal 1717.2 ha mencapai Rp. 724.008.070;90. Kondisi ini diharapkan mampu meningkatkan surplus di sektor kehutanan yang pada akhirnya meningkatkan pertumbuhan PDRB dan peningkatan sarana prasarana pendukung bagi pembangunan wilayah

Perubahan Gaya Hidup Mahasiswa Fakultas Ekonomi Universitas Riau Asal Kecamatan Kandis Sebelum Dan Sesudah Tinggal Di Kota Pekanbaru

Lifestyle is something that is beyond the personality. Lifestyle happens especially in the Faculty of Economics is of respondents noticed a significant change from other Faculties, starting from the change in the dress code that is used by students and staffs who work in that environment. The use of private vehicles ranging from motorcycles and cars that look more numerous than in other Faculties, the use of communication devices such as mobile phones (HP) more updates. With a style of life lived now makes students lose Reviews their critical mind. The purpose of the formulation of the problem is to know the shapes of the lifestyle of students of Faculty of Economics, University of Riau after staying in Pekanbaru and to determine the factors of lifestyle changes that occur in students of the Faculty of Economics, University of Riau. Types of change lifestyle from the students are influenced by advertising a lifestyle, an independent lifestyle, hedonistic lifestyle and their consumer behavior which students inculcate the importance of self-image to appear publicly in advance. Factors affecting changes in economic students of Faculties of this is the influence of attitude, personality, self-concept, motives, perceptions, social class and family. With the problems and objectives that have been Formulated, then the population in this study were all students of economic university Faculties Riau originating from Kandis District using census method or the total amounting to 31 students. This research Data collection instrument was a questionnaire and documentation. In analyzing the data is using quantitative descriptive method. The conclusion of this research is a form of lifestyle changes that occur in the Student Faculty is dominant in the form of an independent lifestyle changes which these students to find out the latest information via various electronic media.
