The Laplace equation governs flow below the surface. The boundary condition on the body is of Neumann type, while on the free surface the nonlinear dynamic free surface condition has to be satisfied. In addition, the farfield and radiation condition, which determine the behaviour of waves going to infinity, have to be satisfied. Taking advantage of the potential flow model, Green Identity is then used to transform the problem of the Laplace equation with nonlinear boundary conation into a nonlinear problem in its boundary. To satisfy the nonlinear dynamic free surface condition, Newton iteration is employed. The scheme for relaxation is obtained by expanding the nonlinear dynamic free surface condition to obtain correction terms to the velocity potential. Truncation up to linear terms results in a simple scheme. Since the dynamic condition is valid on the unknown location of the free surface, in each iteration step the position of the free surface where the equation is applied, is corrected using the Bernoulli equation.

The suppression of noise and vibration by acoustic means are addressed. For the first, an analysis is carried out by representing noise by monopoles and higher harmonics, and to devise a straightforward method to counter their influence by selective secondary acoustic source. The second problem is analyzed using a methodology developed earlier for the computational scheme for the calculation of the acoustic disturbance to the aeroelasticity of structures. The generic approach of the latter consists of three parts. The first is the formulation of the acoustic wave propagation governed by the Helmholtz equation by using boundary element approach, to allow the calculation of the acoustic pressure on the acoustic-structure boundaries.

The Laplace equation governs flow below the surface. The boundary condition on the body is of Neumann type, while on the free surface the nonlinear dynamic free surface condition has to be satisfied. In addition, the farfield and radiation condition, which determine the behaviour of waves going to infinity, have to be satisfied. Taking advantage of the potential flow model, Green Identity is then used to transform the problem of the Laplace equation with nonlinear boundary conation into a nonlinear problem in its boundary. To satisfy the nonlinear dynamic free surface condition, Newton iteration is employed. The scheme for relaxation is obtained by expanding the nonlinear dynamic free surface condition to obtain correction terms to the velocity potential. Truncation up to linear terms results in a simple scheme. Since the dynamic condition is valid on the unknown location of the free surface, in each iteration step the position of the free surface where the equation is applied, is corrected using the Bernoulli equation.

The development of the working principle of solar magnetic sailing from MagSail to magnetospheric plasma propulsion and magneto-plasma-sail is reviewed and discussed to study their performance, focusing on its operation for interplanetary travel. The orbital dynamic of MagSail is elaborated to explore the probable trajectories of interest for space travel. Examples for MagSail interplanetary travel are discussed for insight and future continuing work.","publication_date":{"day":21,"month":11,"year":2018,"errors":{}},"publication_name":"Advances in Astronautics Science and Technology","grobid_abstract_attachment_id":116998314},"translated_abstract":null,"internal_url":"https://www.academia.edu/122305148/Review_of_Solar_Magnetic_Sailing_Configurations_for_Space_Travel","translated_internal_url":"","created_at":"2024-07-23T22:14:43.108-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":4040157,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":116998314,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116998314/thumbnails/1.jpg","file_name":"10.1007_2Fs42423-018-0022-4.pdf","download_url":"https://www.academia.edu/attachments/116998314/download_file?st=MTczMzAzMTQwNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Review_of_Solar_Magnetic_Sailing_Configu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116998314/10.1007_2Fs42423-018-0022-4-libre.pdf?1722127889=\u0026response-content-disposition=attachment%3B+filename%3DReview_of_Solar_Magnetic_Sailing_Configu.pdf\u0026Expires=1732987660\u0026Signature=P-XIzhj7K8CF3ZQ5eOiEBFWAAL2Oh9k7mnlxECIfz~Nr6fYJ19xTUag9GyK8HwicndxHVdrQW5Utsjngcpi5IxXPAWdf2YL4m2hlZs9uZ-MQyTBdGoAa0k0FGvhOglUGDPJPFxtZ-baQxyDM0NtpUZbaMTjjcshaYZq~qaOXPOhpztgDw-55ugKzNU1bDey0uPCBPDN8rx7hCZdRiBjDAG5L9ygyOoqWPWogbtNyc8DJ1bxRGj4PAIB8PZmrvH7kIb1V-XKZ9amzgWSYjeeye3SeKlFCJWWwslZvGJ9RYi-GXy5C6Fw~oIqxLEMBXecvm1mUypTGrFZcvWTPWv-J3Q__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Review_of_Solar_Magnetic_Sailing_Configurations_for_Space_Travel","translated_slug":"","page_count":13,"language":"en","content_type":"Work","owner":{"id":4040157,"first_name":"Harijono","middle_initials":"","last_name":"Djojodihardjo","page_name":"HarijonoDjojodihardjo","domain_name":"itb","created_at":"2013-05-03T11:27:42.148-07:00","display_name":"Harijono Djojodihardjo","url":"https://itb.academia.edu/HarijonoDjojodihardjo"},"attachments":[{"id":116998314,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116998314/thumbnails/1.jpg","file_name":"10.1007_2Fs42423-018-0022-4.pdf","download_url":"https://www.academia.edu/attachments/116998314/download_file?st=MTczMzAzMTQwNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Review_of_Solar_Magnetic_Sailing_Configu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116998314/10.1007_2Fs42423-018-0022-4-libre.pdf?1722127889=\u0026response-content-disposition=attachment%3B+filename%3DReview_of_Solar_Magnetic_Sailing_Configu.pdf\u0026Expires=1732987660\u0026Signature=P-XIzhj7K8CF3ZQ5eOiEBFWAAL2Oh9k7mnlxECIfz~Nr6fYJ19xTUag9GyK8HwicndxHVdrQW5Utsjngcpi5IxXPAWdf2YL4m2hlZs9uZ-MQyTBdGoAa0k0FGvhOglUGDPJPFxtZ-baQxyDM0NtpUZbaMTjjcshaYZq~qaOXPOhpztgDw-55ugKzNU1bDey0uPCBPDN8rx7hCZdRiBjDAG5L9ygyOoqWPWogbtNyc8DJ1bxRGj4PAIB8PZmrvH7kIb1V-XKZ9amzgWSYjeeye3SeKlFCJWWwslZvGJ9RYi-GXy5C6Fw~oIqxLEMBXecvm1mUypTGrFZcvWTPWv-J3Q__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":88,"name":"Aerospace Engineering","url":"https://www.academia.edu/Documents/in/Aerospace_Engineering"},{"id":498,"name":"Physics","url":"https://www.academia.edu/Documents/in/Physics"},{"id":723,"name":"Astrophysical Plasma","url":"https://www.academia.edu/Documents/in/Astrophysical_Plasma"},{"id":137209,"name":"Solar Wind","url":"https://www.academia.edu/Documents/in/Solar_Wind"},{"id":685608,"name":"Interplanetary Magnetic Field","url":"https://www.academia.edu/Documents/in/Interplanetary_Magnetic_Field"},{"id":820041,"name":"Spacecraft","url":"https://www.academia.edu/Documents/in/Spacecraft"}],"urls":[{"id":43662295,"url":"https://link.springer.com/content/pdf/10.1007/s42423-018-0022-4.pdf"}]}, dispatcherData: dispatcherData });

The suppression of noise and vibration by acoustic means are addressed. For the first, an analysis is carried out by representing noise by monopoles and higher harmonics, and to devise a straightforward method to counter their influence by selective secondary acoustic source. The second problem is analyzed using a methodology developed earlier for the computational scheme for the calculation of the acoustic disturbance to the aeroelasticity of structures. The generic approach of the latter consists of three parts. The first is the formulation of the acoustic wave propagation governed by the Helmholtz equation by using boundary element approach, to allow the calculation of the acoustic pressure on the acoustic-structure boundaries.

Analytical approach is usually preferred due to its convenience for parametric studies, however such an approach can usually be followed for limited class of geometries only. In the present work, a method which was proposed by Barboni, Gaudenzi, Mannini and Santini, which modified the well known transfer matrix method by expanding the governing differential equations for the structural state vector into a power series, with the power related to the eigenvalues of the dynamic eigenvalue problem, is followed and rederived.

Results for two and three dimensional nonlifting problem are presented as examples."},"translated_abstract":"A simple method to solve potential flow problem of submerged body-surface wave interaction is presented. The equation governing flow below the surface is Laplace equation. The boundary condition on the body is of Neumann type, while on the free surface the nonlinear dynamic free surface condition has to be satisfied. In addition, farfield and radiation condition, which determine the behavior of wave going to infinity, have to be satisfied. Taking advantage of potential flow model, then Green Identity is used to transform the problem of Laplace equation with nonlinear boundary condition into 'a nonlinear problem in its boundary. To satisfy the nonlinear dynamic free surface condition, Newton iteration is employed. The scheme for relaxation is obtained by expanding the nonlinear dynamic free surface condition obtain correction terms to the velocity potential. Truncation up to linear terms results in a simple scheme. Since the dynamic condition is valid on the unknown location of the free surface, in each iteration step the position of the free surface where the equation is applied, is corrected using Bernoulli equation. In this manner, dynamic free surface condition is satisfied exactly at the collocation points. Results for two and three dimensional nonlifting problem are presented as examples.","internal_url":"https://www.academia.edu/30323737/Numerical_Boundary_Element_Computation_of_Submerged_Body_Surface_Wave_Interaction","translated_internal_url":"","created_at":"2016-12-08T00:24:12.587-08:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":4040157,"coauthors_can_edit":true,"document_type":"conference_presentation","co_author_tags":[{"id":26453772,"work_id":30323737,"tagging_user_id":4040157,"tagged_user_id":null,"co_author_invite_id":5831517,"email":"b***a@gmail.com","display_order":1,"name":"B.Bimo Prananta","title":"Numerical Boundary Element Computation of Submerged Body-Surface Wave Interaction"}],"downloadable_attachments":[{"id":50779720,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/50779720/thumbnails/1.jpg","file_name":"Djojodihardjo_Numerical_Boundary_Element_Computation_of_Submerged_Body-Surface_Wave_Interaction_-_ISOPE-I-93-259.pdf","download_url":"https://www.academia.edu/attachments/50779720/download_file?st=MTczMzAzMTQwNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Numerical_Boundary_Element_Computation_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/50779720/Djojodihardjo_Numerical_Boundary_Element_Computation_of_Submerged_Body-Surface_Wave_Interaction_-_ISOPE-I-93-259-libre.pdf?1481185920=\u0026response-content-disposition=attachment%3B+filename%3DNumerical_Boundary_Element_Computation_o.pdf\u0026Expires=1732987662\u0026Signature=PmHuUkDjqCMab8YK6MYGRSSz3LYUWCcoSforcTE5gIUkiG9p1X95JbBWXtZmQ5auEcbuwii55o8ZJaK363TNLqGhq~uEKqWg09BSd7tUW0X3uyUWsdovPrKbYo92oOBBc6-g~tzaYV1kDLzrVDVUJC9NceTRmk7qPld62C9scD2EbBJJD4vbsU2rlgGgLiUkbL~pskIKIZN7bcgbESIuxhG9qxvZ2ZvfKTrlIpaZjrIm6mMvFWMlBKmkMQEwU6GfjhZxTwqTN3D1I0EBL6P9JGd7AQhjwDgMolSCme-0Q5nqNNwejI8spkIwsRy3Hu1BzyBMmjFgQJWoDxSIZTm5VQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Numerical_Boundary_Element_Computation_of_Submerged_Body_Surface_Wave_Interaction","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":4040157,"first_name":"Harijono","middle_initials":"","last_name":"Djojodihardjo","page_name":"HarijonoDjojodihardjo","domain_name":"itb","created_at":"2013-05-03T11:27:42.148-07:00","display_name":"Harijono Djojodihardjo","url":"https://itb.academia.edu/HarijonoDjojodihardjo"},"attachments":[{"id":50779720,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/50779720/thumbnails/1.jpg","file_name":"Djojodihardjo_Numerical_Boundary_Element_Computation_of_Submerged_Body-Surface_Wave_Interaction_-_ISOPE-I-93-259.pdf","download_url":"https://www.academia.edu/attachments/50779720/download_file?st=MTczMzAzMTQwNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Numerical_Boundary_Element_Computation_o.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/50779720/Djojodihardjo_Numerical_Boundary_Element_Computation_of_Submerged_Body-Surface_Wave_Interaction_-_ISOPE-I-93-259-libre.pdf?1481185920=\u0026response-content-disposition=attachment%3B+filename%3DNumerical_Boundary_Element_Computation_o.pdf\u0026Expires=1732987662\u0026Signature=PmHuUkDjqCMab8YK6MYGRSSz3LYUWCcoSforcTE5gIUkiG9p1X95JbBWXtZmQ5auEcbuwii55o8ZJaK363TNLqGhq~uEKqWg09BSd7tUW0X3uyUWsdovPrKbYo92oOBBc6-g~tzaYV1kDLzrVDVUJC9NceTRmk7qPld62C9scD2EbBJJD4vbsU2rlgGgLiUkbL~pskIKIZN7bcgbESIuxhG9qxvZ2ZvfKTrlIpaZjrIm6mMvFWMlBKmkMQEwU6GfjhZxTwqTN3D1I0EBL6P9JGd7AQhjwDgMolSCme-0Q5nqNNwejI8spkIwsRy3Hu1BzyBMmjFgQJWoDxSIZTm5VQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":81,"name":"Ocean Engineering","url":"https://www.academia.edu/Documents/in/Ocean_Engineering"},{"id":88,"name":"Aerospace Engineering","url":"https://www.academia.edu/Documents/in/Aerospace_Engineering"},{"id":2298,"name":"Computational Fluid Dynamics","url":"https://www.academia.edu/Documents/in/Computational_Fluid_Dynamics"},{"id":2435,"name":"Fluid Mechanics","url":"https://www.academia.edu/Documents/in/Fluid_Mechanics"},{"id":4955,"name":"Computational Modelling","url":"https://www.academia.edu/Documents/in/Computational_Modelling"},{"id":15532,"name":"Marine Engineering","url":"https://www.academia.edu/Documents/in/Marine_Engineering"}],"urls":[]}, dispatcherData: dispatcherData });

To this end, anticipating potential air transportation markets in the business jet type, the present work is devoted for exploring the possibilities of introducing some of a number of visionary and pioneering ideas and upcoming enabling technologies within Green and N+2 Aircraft framework in the Aerodynamic and Conceptual Design Study of Quad-Bubble Business Jet (QB-BJ). In view of and driven by the vision for a fuel efficient, environmentally friendly and technology driven aircraft to meet global need within the next 15 years, the characteristics of the conceptually designed aircraft will be assessed in comparison to an appropriately chosen business jet as a reference, as well as recent novel concepts, within the subsonic flight regimes. Major ideas derived from D8 and other novel concepts are appropriately applied in the work, which starts with fuel efficient motivation, and followed by wing Aerodynamics and other critical factors related to the Design Requirements and Objectives.

Each food is accompanied by a picture, and is written in Latin (Roman) characters, so that although the book is written in Indonesian, it may be comprehensible for many other readers.","internal_url":"https://www.academia.edu/104266047/HDS_MAKANAN_KESUKAANKU_HD_MS_AH","translated_internal_url":"","created_at":"2023-07-05T08:26:29.569-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":4040157,"coauthors_can_edit":true,"document_type":"book","co_author_tags":[],"downloadable_attachments":[{"id":104042022,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104042022/thumbnails/1.jpg","file_name":"HDS_MAKANAN_KESUKAANKU_HD_MS_AH.pdf","download_url":"https://www.academia.edu/attachments/104042022/download_file?st=MTczMzAzMTQwNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"HDS_MAKANAN_KESUKAANKU_HD_MS_AH.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104042022/HDS_MAKANAN_KESUKAANKU_HD_MS_AH-libre.pdf?1688572222=\u0026response-content-disposition=attachment%3B+filename%3DHDS_MAKANAN_KESUKAANKU_HD_MS_AH.pdf\u0026Expires=1732987662\u0026Signature=IX7NwQd9aBIUFcMBjx5y53B0g-IZXi2Ql-gm5C6MPrruZOCtoQlL6vchorWuPhiDfttc7gkPsGreE9Qa5XxoSCpVLJBP7QqT~G4FK9~4TnDSFAsMYseMMV5PbGxdhMsuoQ11KRbHMQyPxBGDPBZnQWnfvU8747T7fPYTICL1WQCgC7b1ow4USX6akBKn1JamfZt3vPvlRdMWTt4D1t8Vsy1UhGKbMrGv2ycBa-pKAQlEePJozFkDZkD3pZHlBfGLVRTW0nNI-xe92dL0W1h6EELEdjzhu32Obe6twfEmrMMfhpq4eI~IreDPjGKnwQ9avSTHnaDjD0-qD2rXxKP0LA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"HDS_MAKANAN_KESUKAANKU_HD_MS_AH","translated_slug":"","page_count":286,"language":"id","content_type":"Work","owner":{"id":4040157,"first_name":"Harijono","middle_initials":"","last_name":"Djojodihardjo","page_name":"HarijonoDjojodihardjo","domain_name":"itb","created_at":"2013-05-03T11:27:42.148-07:00","display_name":"Harijono Djojodihardjo","url":"https://itb.academia.edu/HarijonoDjojodihardjo"},"attachments":[{"id":104042022,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/104042022/thumbnails/1.jpg","file_name":"HDS_MAKANAN_KESUKAANKU_HD_MS_AH.pdf","download_url":"https://www.academia.edu/attachments/104042022/download_file?st=MTczMzAzMTQwNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"HDS_MAKANAN_KESUKAANKU_HD_MS_AH.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/104042022/HDS_MAKANAN_KESUKAANKU_HD_MS_AH-libre.pdf?1688572222=\u0026response-content-disposition=attachment%3B+filename%3DHDS_MAKANAN_KESUKAANKU_HD_MS_AH.pdf\u0026Expires=1732987662\u0026Signature=IX7NwQd9aBIUFcMBjx5y53B0g-IZXi2Ql-gm5C6MPrruZOCtoQlL6vchorWuPhiDfttc7gkPsGreE9Qa5XxoSCpVLJBP7QqT~G4FK9~4TnDSFAsMYseMMV5PbGxdhMsuoQ11KRbHMQyPxBGDPBZnQWnfvU8747T7fPYTICL1WQCgC7b1ow4USX6akBKn1JamfZt3vPvlRdMWTt4D1t8Vsy1UhGKbMrGv2ycBa-pKAQlEePJozFkDZkD3pZHlBfGLVRTW0nNI-xe92dL0W1h6EELEdjzhu32Obe6twfEmrMMfhpq4eI~IreDPjGKnwQ9avSTHnaDjD0-qD2rXxKP0LA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":803,"name":"Philosophy","url":"https://www.academia.edu/Documents/in/Philosophy"},{"id":7125,"name":"Culture","url":"https://www.academia.edu/Documents/in/Culture"},{"id":25286,"name":"Culinary Culture","url":"https://www.academia.edu/Documents/in/Culinary_Culture"},{"id":125863,"name":"Applied Mathematics and Computational Science","url":"https://www.academia.edu/Documents/in/Applied_Mathematics_and_Computational_Science"},{"id":133105,"name":"Classical piano music","url":"https://www.academia.edu/Documents/in/Classical_piano_music"},{"id":1264719,"name":"Earth and Space Sciences","url":"https://www.academia.edu/Documents/in/Earth_and_Space_Sciences"},{"id":1410015,"name":"Aerospace Engineering and Aeronautical Engineering","url":"https://www.academia.edu/Documents/in/Aerospace_Engineering_and_Aeronautical_Engineering"},{"id":2867299,"name":"Gastronomy and Culinary Arts","url":"https://www.academia.edu/Documents/in/Gastronomy_and_Culinary_Arts"}],"urls":[]}, dispatcherData: dispatcherData });

Then, what should be written should be something that the author has learned and like to share with his children, grandchildren, relatives, students and former students alike, and more importantly to the interested readers and mankind. It is by no means an autobiography or memoir, but something like a part of a “flashback”, that may represent my “accountability” in life. Having spent a large part of my life in academia, as a civil servant in government institutions dealing with science and technology, and partly in industry, but realizing that no extraordinary achievement have been delivered to the public, it seems appropriate that I would start from how and why what I have been doing began. It appears to me that all of these started from “my dream”, and from what I have been thankful, my capability to use my “reasoning capability”. This is something that need more thoughtful elaboration, and this is all about the book. My dream and why I have dreamed. I just want to share this dream and how I have been attempting to realize this dream through  a life paradigm that I dubbed “Being Together” reflecting the high-values of mankind reflected by many, if not all religions, that is Love, Care, Share, Give and Serve. In my mother’s tongue Javanese, this is expressed as “Guyub: Tresno, Gumati, Asih-Asih-Asuh, Caos, Laden”. I cannot claim I have delivered many down-stream products to mankind and universe, but I have a dream and started to interact with mankind and nature from upstream and from within my deep-self, by using the most sacred gift from God-All-Mighty, my “reasoning capability”, with the objective to contribute to the development of the culture of the society that should be so based, though my expertise. The latter goes on the scientific attitude and scientific culture, to expansion and sharing with associates the dream to generate the following dreams. As cases in point, writings and presentations, are ways of expressing your dream to certain extent, disseminating ideas and interact with co-workers, mostly young and inspiring young colleagues. These I found gratifying.  <br />With such background, the book is intended by the author to contribute in the long run to the cultural development and transformation of the nation, along the line of the historical progress of mankind, for the development of the nation to acquire smart and competitive culture. And that dictates the title of the book INGENUITY FOR NATIONAL CULTURE. Starting from basic philosophical point of views, motivation and ideas are elaborated. The product of the dream and reasoning capabilities that have been enjoyed by the author are exemplified in other dreams: presentations and scientific work in partnership with co-workers that represent development efforts, which could still comprise further scientifically elaborated dreams. For the author, the choice of the title of the book is natural and intuitional. <br />To complement the ideas elaborated in the chapters, the author provides a detailed biography. Having completed his engineering education at the Institute of Technology of Bandung (ITB), University of Kentucky and Massachusetts Institute of Technology (MIT) , he has served as academic faculty member at ITB and other universities, at the Government Science and Technology Offices such as The Indonesian Space Agency (LAPAN), the Agency for the Assessment and Application of Technology (BPPT), The Indonesia Aircraft Industry (PT IPTN, now PT DI) and the Office of the President, among others. These experiences have strengthened his motivation and dedication to contribute pro-actively for the cultural development of his Nation, at his capacity as a member of the silent moral force.<br />At the beginning of the writing, the book contains chapters in Indonesia and English, following the relevant event presented. Constructive suggestions by reviewers  lead to the split up of the book into two versions. One, a shorter version in Indonesian, and another one, a most complete delivery of the ideas in English. The present one is the latter. In elaborating the ideas following the dream and motivation, the chapters are divided into two groups, Macro-Aspects and Micro-Aspects. <br />The biography of the author is elaborated in some detail en-lieu of elaborating it in the main text to provide further background for the essays contained in the main body of the book.<br />As a closing remark, the author would like to thank many individuals that have given constructive suggestions to the preliminary edition of the book.

Two suppression methods for noise and vibration, both by acoustic means, are addressed. For the first problem, an analysis is carried out on the representation of noise by monopoles and their higher harmonics, and to devise a straightforward method to counter their influence by selective secondary acoustic source. The second problem is analyzed using a methodology developed earlier for the computational scheme for the calculation of the acoustic disturbance to the aeroelasticity of structures. The generic approach of the latter consists of three parts.
