Telah dilakukan karakterisasi reservoar hidrokarbon pada Lapangan Penobscot Kanada mengunakan metode seismik inversi deterministik model based. Penelitian ini mengunakan data seismik PSTM (post stack time migration) 3D pada inline 1300 sebagai data input dan data sumur L30 dan B41 sebagai data kontrol. Karakterisasi reservoar dilakukan dengan melakukan analisis crossplot dan menentukan nilai impedansi akustik atau acoustic impedance (AI). Analisis crossplot menunjukkan bahwa log gamma ray sensitif dalam pemisahan lapisan shale, sandstone, dan limestone. Penentuan zone of interest yang diindikasikan sebagai reservoar hidrokarbon dilakukan melalui analisis atribut dekomposisi spektral dengan frekuensi 10 Hz. Hal tersebut menunjukkan dengan jelas kemenerusan pola penyebaran litologi yang diduga sebagai hidrokarbon dengan lebih mudah. Hasil inversi deterministik model based menunjukkan bahwa pada inline 1300 terdapat potensi hidrokarbon melalui sebaran nilai impedansi akustik. Slicing yang dilakukan pada lapisan zone of interest menunjukkan hasil sebaran nilai impedansi akustik dengan rentang 13556-27501(m/s)*(g/cc). Potensi reservoar hidrokarbon sandstone ditunjukkan melalui zona impedansi akustik pada nilai 20000-25461 (m/s)*(g/cc). Kata kunci: atribut dekomposisi spektral, impedansi akustik, inversi deterministik, model based, zone of interest

Satuan stratigrafi dari karbonat tebal akibat siklus sedimen yang terendapkan di wilayah Zagros pesisir selatan Neotitis, Iran dikenal dengan formasi Sarvak sebagai rangkaian karbonat yang tersusun atas batuan sedimen non – klastik sebagai penghasil hidrokarbon yang signifikan. Perbedaan nilai vp yang didapat pada tiap lapisan membuat penelitian ini ingin mengetahui kisaran nilai impedansi akustik pada lapisan karbonat formasi sarvak dengan Persamaan Gassman dan juga Differential Effective Medium (DEM). Gassman yang digunakan secara luas dalam industri minyak dan gas dapat mengidentifikasi fluida serta pemantauan reservoir, sedangkan Differential Effective Medium (DEM) dapat memprediksi sifat elastis batuan agregat berpori pada semua jenis batuan tanpa asumsi spesifik seperti Gassman. Pengukuran kecepatan gelombang P batuan karbonat menggunakan alternatif lain (metode DEM) akibat asumsi Gassman yang tidak valid. Setelah didapat nilai kecepatan gelombang P pada formasi Sarvak, kisaran nilai impedansi pada tiap lapisan didapatkan. Kisaran tersebut dapat mengidentifikasi litologi lapisan formasi Sarvak menggunakan klasifikasi tabel 1 dan 2. Pada praktiknya, klasifikasi menurut tabel 1 dan 2 tidak sinkron hanya dengan salah satu indikator yaitu vp saja atau impedansi akustik saja, sehingga dibutuhkan penelitian lanjutan untuk mengetahui karakterisasi batuan penyusun litologi menggunakan software AVO, data log, serta parameter pendukung lainnya seperti EEI (Extended Elastic Impedance).

Ruang kuliah membutuhkan persyaratan akustik yang optimal agar kegiatan belajar-mengajar bisa berjalan dengan baik. Waktu dengung yang terlalu panjang menyebabkan suara dari dosen menjadi kurang jelas terdengar oleh mahasiswa. Kaca jendela mempunyai nilai α (koefisien absorbsi bunyi) yang rendah sehingga dapat memperpanjang waktu dengung. Lantai mempunyai luas permukaan dominan dalam suatu ruangan. Rendahnya nilai α kaca jendela dan luasnya permukaan lantai berpengaruh besar terhadap nilai waktu dengung. Tujuan penelitian ini adalah menemukan model lantai dan jendela di ruang kuliah yang paling optimal waktu dengungnya.
Ruang kuliah Wastu 1, Universitas Tarumanagara, Jakarta dijadikan sampel penelitian. Metode yang digunakan adalah metode eksperimen. Ruang kuliah kondisi eksisting dan 5 model lantai dan jendela disimulasikan ke dalam Autodesk Ecotect Analysis 2011 untuk mengetahui perbandingan waktu dengungnya. Hasil penelitian membuktikan bahwa model ruangan yang menggunakan lantai karpet dan panggung karpet setinggi 30 cm dan jendela yang menggunakan double glazed aluminium frame mempunyai RT paling mendekati standard. Penggunaan karpet pada lantai dan double glazed aluminium frame pada jendela mampu menurunkan waktu dengung karena kedua material tersebut mempunyai nilai α yang cukup tinggi.

Underwater acoustic sampling techniques provide an advantage over traditional net-sampling for zooplankton research. The research presents a methodology for extracting both biological and physical information from high frequency sonar. These methods can easily provide the information that will improve our understanding of the spatial and temporal distribution of zooplankton. Measured acoustic data converted into biological organisms and numerical physics-based scattering models were used in this research. The numerical backscattering process was modeled using the Distorted-Wave Born Approximation (DWBA) to predict the amount of sound scattered by a weakly scattering animal. Both acoustic measurement and DWBA modeled scattering patterns showed that acoustic scattering levels are highly dependent on zooplankton orientation. The acoustic backscattering from zooplankton depends on the material properties (i.e. the sound speed and density of the zooplankton), the shape and size, and the orientation relative to the incident acoustic wave. DWBA model significantly improve the accuracy and precision of zooplankton acoustic surveys. Zooplankton data measurement and DWBA model analysis provide a basis for future acoustical studies.

The use of high-density loudspeaker arrays (HDLAs) has recently experienced rapid growth in a wide variety of technical and aesthetic approaches. Still less explored, however, are applications to interactive music with live acoustic instruments. How can immersive spatialization accompany an instrument already with its own rich spatial diffusion pattern, like the grand piano, in the context of a score-based concert work? Potential models include treating the spatialized electronic sound in analogy to the diffusion pattern of the instrument, with spatial dimensions parametrized as functions of timbral features. Another approach is to map the concert hall as a three-dimensional projection of the instrument's internal physical layout, a kind of virtual sonic microscope. Or, the diffusion of electronic spatial sound can be treated as an independent polyphonic element, complementary to but not dependent upon the instrument's own spatial characteristics. Cartographies (2014), for piano with two performers and electronics, explores each of these models individually and in combination, as well as their technical implementation with the Meyer Sound Matrix3 system of the Südwestrundfunk Experimentalstudio in Freiburg, Germany, and the 43.4-channel Klangdom of the Institut für Musik und Akustik at the Zentrum für Kunst und Media in Karlsruhe, Germany. The process of composing, producing, and performing the work raises intriguing questions, and invaluable hints, for the composition and performance of live interactive works with HDLAs in the future.

ABSTRAK Karakterisasi reservoir menjadi penting dalam tahapan eksplorasi minyak dan gas bumi. Salah satu hal yang dibutuhkan untuk mencapai keakuratan dalam mengkarakterisasi reservoir adalah penampang seismik yang sesuai dengan penampang aslinya. Struktur lapisan bumi yang kompleks mengakibatkan gelombang terdifraksi, sehingga penampang seismik mengalami pembelokan dari posisi sebenarnya. Penelitian ini menerapkan metode migrasi seismik Kirchhoff dan Stolt (F-K) untuk mengembalikan posisi reflektor pada waktu dan kedalaman yang sebenarnya pada data seismik 2D di Perairan Utara Bali. Data seismik diintegrasikan dengan data sumur APS-1 sebagai kontrol untuk diinversikan dengan teknik inversi berbasis model sehingga dapat mengkarakterisasi reservoir. Penelitian ini bertujuan membandingkan hasil migrasi seismik yaitu migrasi Stolt dan migrasi Kirchhoff untuk diinversikan menggunakan metode inversi berbasis model sehingga dapat diketahui sejauh mana kualitas data seismik mempengaruhi proses karakterisasi reservoir. Nilai korelasi dari hasil analisis regresi antara log impedansi inversi dengan log impedansi data sumur pada migrasi Kirchhoff sebesar 0,739 dan galat regresi sebesar 873,54, sedangkan pada migrasi Stolt memiliki nilai korelasi sebesar 0,698 dan nilai galat sebesar 1236,17. Hal ini menunjukkan bahwa migrasi Kirchhoff lebih baik dari migrasi Stolt baik secara kualitatif maupun kuantitatif dalam mengkarakterisasi reservoir hidrokarbon. ABSTRACTReservoir characterization is an important method in gas and oil exploration. In order to obtain accuracy for defining reservoir, required seismic image that similar to the actual seismic image. The complexity of earth structure could cause diffracted waves, therefore, seismic image was diffracted from its actual position. This study applies Kirchhoff and Stolt (F-K) seismic migration methods to restore the position of the reflector at the actual time and depth seismic data in North Bali. Seismic data is integrated with APS-1 well data as controls to be converted with model-based inversion techniques so as to characterize the reservoir. This study aims to compare the results of seismic migration namely Stolt and Kirchhoff migration to be converted using a model-based inversion method so that it can be seen to what extent the quality of seismic data influences the reservoir characterization process. Correlation value from the results of regression analysis between inversion log impedance and well impedance log data in Kirchhoff migration is 0.739 and regression error is 873.54, while the Stolt migration has a correlation value of 0.698 and an error value of 1236.17. This shows that Kirchhoff's migration is better than Stolt migration both qualitatively and quantitatively in characterizing hydrocarbon reservoirs.

In the paper the theoretical consideration of the acoustic metamaterials is given. Metamaterials, which are usually composite, are artificial materials whose properties differ from those observed in nature or in the constituent materials. Metamaterials which are suitable for acoustic wave absorption are presented. Acoustic absorber is a beam made of solid material connected with spring-mass subunits. The purpose of the subunits is to give a band gap where some frequencies of acoustic wave are stopped. Mathematical models for various types of connection of subunits in the metamaterial and absorber are discussed. Based on the analogy between electromagnetic and acoustic waves the concept of negative effective mass is introduced as a basic principle for modeling. Acoustic metamaterial beams based on one, two or multi-frequency vibration absorbers are discussed. Depending on connection of absorbers in the beam, the structure may absorb wave in one-direction (for example the longitudinal one) or waves in two directions (transversal and longitudinal). In the paper an overview of mathematical models and suggestions for further investigation are given.

This thesis deals with the properties of soundproof partition structures in the low-frequency sound at impact sound insulation and security of acoustic comfort inside buildings. The prediction of impact sound is a simulation laboratory measurements of impact sound. The work is based on the occurrence of frequent complaints of inhabitants of residential homes for subjectively poor impact sound insulation of horizontal dividing structures, whose top layer is formed laminate. Although these structures conform in terms of impact sound insulation in accordance with the requirements of CSN 73 0532: 2010, residents complain about the subjective perception of the sounds of lower frequencies. A noise with a distinctive character of sound at low frequencies has been proved by measuring the spectral analysis and evaluation of sound pressure levels caused by the movement of persons roof construction to the floor. On the measurement and evaluation carried out in accordance with the measurement and evaluation of noise in non-working environment can be related requirement under the Regulation No. 272/2011 Coll. "On the protection of health from the adverse effects of noise and vibration." Occupational noise limits for protected buildings interior space do not apply to noise from ordinary use of the apartment. Under current legislation, the problem is in the Czech Republic at present insoluble. Therefore, this work explores ways evaluation of impact sound and delivery is determined conclusions. With the low-frequency impact sound insulation is also related to the latter part of this dissertation, where the computing program ANSYS (version 14.0) is simulated laboratory measurements of impact sound insulation of the real structure. The paper presents the results of simulation, and the sound pressure level in the receiving room to třetinooktávového band 630 Hz. These results are compared with measured values modeled in the laboratory.

An adaptable binaural model for surround sound has been developed in this master’s thesis. The adaptability is based on measurements of the listener’s head. This model is based on what was found to be the best suited material combination of successful models in earlier studies. This includes an ellipsoidal model for interaural time difference, an one-pole, one-zero head shadow filter and the use of Blauert’s directional bands for spectral manipulation. The model can play back six channel surround content using the standardized 5.1 surround sound loudspeaker setup. This standardized loudspeaker placement is used when creating virtual sound sources. Arbitrary sound directions are made in the horizontal plane by creating virtual sound sources using vector base amplitude panning between the standardized loudspeaker positions.To test the performance of this model, a listening test was conducted. The hypothesis tested was that the adaptable model would produce equal or lower localization error, compared to the commercial model. 20 test subjects participated. The test featured three different test types; standardized 5.1 loudspeaker setup, a commercial model for surround sound in headphones, and the adaptable model. Localization accuracy for ten selected directions in the right half plane was tested. The results from the adaptable model were compared to the result of the commercial model. The loudspeaker setup acted as a reference.Mean localization error was found to be thrice as high for the adaptable model, compared to the commercial model. Both models had the same standard deviation. 95% of the confidence intervals for these models did not overlap, i.e. there is a significant difference between the two methods. With this one can safely conclude that the commercial model provided a smaller localization error than the adaptable model. Hence the hypothesis has to be disproved.Both the commercial model and the thesis model performed significantly worse than the loudspeaker setup. One difference between commercial model, and the thesis model, was that that the commercial model had added room reflections and reverberation. This can create the sensation that the sound is coming from outside the head, and make it easier to localize. This contradicts with the knowledge that reverberation diffuses the sound field, making the direct sound that provides the directional information become less prominent.

Der volle Inhalt der QuelleAnnotation:
This thesis is a step towards the long-term and high-reaching objec-tive of building dialogue systems whose behaviour is similar to a human dialogue partner. The aim is not to build a machine with the same conversational skills as a human being, but rather to build a machine that is human enough to encourage users to interact with it accordingly. The behaviours in focus are cue phrases, hesitations and turn-taking cues. These behaviours serve several important communicative functions such as providing feedback and managing turn-taking. Thus, if dialogue systems could use interactional cues similar to those of humans, these systems could be more intuitive to talk to. A major part of this work has been to collect, identify and analyze the target behaviours in human-human interaction in order to gain a better understanding of these phenomena. Another part has been to reproduce these behaviours in a dialogue system context and explore listeners’ perceptions of these phenomena in empirical experiments. The thesis is divided into two parts. The first part serves as an overall background. The issues and motivations of humanlike dialogue systems are discussed. This part also includes an overview of research on human language production and spoken language generation in dialogue systems. The next part presents the data collections, data analyses and empirical experiments that this thesis is concerned with. The first study presented is a listening test that explores human behaviour as a model for dialogue systems. The results show that a version based on human behaviour is rated as more humanlike, polite and intelligent than a constrained version with less variability. Next, the DEAL dia-logue system is introduced. DEAL is used as a platform for the re-search presented in this thesis. The domain of the system is a trade domain and the target audience are second language learners of Swedish who want to practice conversation. Furthermore, a data collection of human-human dialogues in the DEAL domain is presented. Analyses of cue phrases in these data are provided as well as an experimental study of turn-taking cues. The results from the turn-taking experiment indicate that turn-taking cues realized with a di-phone synthesis affect the expectations of a turn change similar to the corresponding human version. Finally, an experimental study that explores the use of talkspurtinitial cue phrases in an incremental version of DEAL is presented. The results show that the incremental version had shorter response times and was rated as more efficient, more polite and better at indicating when to speak than a non-incremental implementation of the same system.QC20100830
