Numerical study of contra-rotating Vertical Axis Wind Turbine H-Rotor Darrieus type / Aditya Ilham Setyawan Haryogo, Vivien S. Djanali and Bagus Nugroho
No full textThe new Contra-rotating Darrieus turbine configuration has been invented to enhance the Vertical Axis Wind Turbine (VAWT) performance. This configuration increases the relative rotational speed of the generator, resulting in higher output power. It is well known that the increase can reach four times the output power. However, how the Darrieus turbine VAWT contrarotating configuration influences its aerodynamic performance still needs to be discovered. This study investigates the aerodynamic performance of the contra-rotating configuration by comparing it to the single-rotating Darrieus turbine VAWT under the same conditions. The freestream speed is 5 m/s, with TSR varying from one to two intervals of 0.2. This research is being completed using Computational Fluid Dynamics (CFD) 3D cases with an Unsteady Reynold Average Navier-Stokes (URANS) equation as the turbulent model equation. The results of this study show that in terms of output power or Power coefficient (Cp), the contra-rotating has a greater value than the singlerotating configuration. However, in all TSR variations, contra-rotating outperforms single-rotating in terms of aerodynamic performance or moment coefficient (Cm). This is due to the fact that the aspect ratio of stage 1 contra-rotating rotor is lower than the single-rotating rotor, resulting in more significant blade tip losses in contra-rotating. The flow was discovered through the gap between stages 1 and 2 contra-rotating, providing additional momentum. This phenomenon increases Cm at an azimuth angle of 200°-255°

Design, modeling and real-time monitoring of continuous powder mixing processes
No full textContinuous processing is an advantageous alternative for the current methods used in the pharmaceutical manufacturing. Important advantages that it offers include smaller equipment footprint, reduced efforts in the scale-up work, and the potential to utilize already continuous processes to make the entire manufacturing more efficient. In the current pharmaceutical manufacturing environment, powder mixing process is carried out in the batch mode. The necessary methods and guidelines to design an equivalent continuous process are not well established. The work presented in this dissertation focuses on the characterization, design and optimization of a continuous powder mixing process for pharmaceutical powders. A systematic study was performed of the effects of process and design variables, and material properties involved in the continuous powder mixing process. The bulk powder flow behavior was characterized using the residence time distribution (RTD) measurement approach. Impeller speed, material bulk density and impeller design greatly influenced the mean residence time. With increasing impeller speed, mechanical fluidization was observed, which significantly affected axial dispersion coefficients. Intermediate rotation rates exerted maximum strain on the material, which leads to maximum homogenization. The strain measurements correlated well with the properties of tablets including content uniformity and tablet hardness. Mixing performance was largely dominated by the material properties of the mixture, and the blend uniformity measurement was affected by the sample size analyzed. An experimental protocol was developed to measure the blend uniformity in the in-line mode, and a methodology was further built to quantitatively relate the in-line NIR measurements with the off-line wet chemistry measurements. Considering the shear limitations of the continuous bladed mixer, alternative blending strategies, suitable for blending of cohesive materials were also demonstrated. A combination of a high-shear mixing followed by a low-shear mixing process provided the optimal mixing performance. The predictive understanding of the continuous powder mixing process developed in this dissertation can assist towards the design and development of a fully controlled continuous manufacturing process.Ph.

On the two-potential constitutive modelling of rubber viscoelastic materials
No full textU of I Only Restriction Lifted for Item 93166 on 2018-07-08T09:15:36Z."This work lays out the specialization of the two-potential constitutive framework --- also known as the ""generalized standard materials'' framework --- to rubber viscoelasticity. Inter alia, it is shown that a number of popular rubber viscoelasticity formulations, introduced over the years following different approaches, are special cases of this framework. As a first application of practical relevance, the framework is utilized to put forth a new objective and thermodynamically consistent rubber viscoelastic model for incompressible isotropic elastomers. The model accounts for the non-Gaussian elasticity of elastomers, as well as for the deformation-enhanced shear thinning of their viscous dissipation governed by reptation dynamics. The descriptive and predictive capabilities of the model are illustrated via comparisons with experimental data available from the literature for two commercially significant elastomers."Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Aditya Kumar, accepted the attached license on 2016-04-21 at 16:42.The student, Aditya Kumar, submitted this Thesis for approval on 2016-04-21 at 17:40.This Thesis was approved for publication on 2016-04-25 at 13:53.DSpace SAF Submission Ingestion Package generated from Vireo submission #9421 on 2016-07-07 at 13:50:34Made available in DSpace on 2016-07-07T20:27:55Z (GMT).

ABSTRAK
Latar Belakang: Pulih sadar dari general anestesi diartikan sebagai keadaan
dimana kesadaran seseorang telah kembali penuh setelah selesainya tindakan
operasi. Periode yang dibutuhkan pasien dalam mencapai keadaan pulih sadar
disebut dengan waktu pulih sadar. Jika dalam waktu 15 menit setelah selesai
pemberian obat anestesi namun pasien masih dalam keadaan tidak sadar disebut
delayed waktu pulih sadar. Delayed waktu pulih sadar memiliki banyak dampak
buruk, seperti peningkatan resiko terjadinya sumbatan jalan nafas, aspirasi pada
pasien, koma hingga kematian. Tata laksana dalam mencegah delayed waktu pulih
sadar pasien dapat melalui 2 cara, yaitu dengan terapi farmakologi dan non
farmakologi. Terapi komplementer merupakan terapi yang digunakan sebagai
pendamping terapi farmakologi yang digunakan untuk mempercepat pemulihan.
Dzikir merupakan salah satu terapi komplementer, dzikir membuat tubuh
mengalami keadaan santai (relaksasi). Sehingga membuat pasien lebih cepat
sadar.
Tujuan: Penelitian ini bertujuan untuk mengetahui pengaruh terapi dzikir
terhadap waktu pulih sadar pasien pasca general anestesi di Rumah Sakit Paru dr.
Ario Wirawan Salatiga.
Metode: Desain penelitian yang digunakan bersifat quasy eksperiment.
Responden penelitian berjumlah 36 orang, yang merupakan pasien yang menjalani
operasi dengan tata laksana general anestesi di RS Paru dr. Ario Wirawan
Salatiga. Teknik pengambilan sampel menggunakan purposive sample. Dalam
penelitian ini terdapat dua kelompok, yaitu kelompok kontrol (tidak diberikan
terapi) dan kelompok perlakuan (diberikan intervensi terapi dzikir), Untuk
menguji perbandingan waktu pulih sadar antara kelompok kontrol dengan
kelompok intervensi, maka dilakukan uji Mann Whitney
Hasil: Dari hasil penelitian, didapatkan bahwa nilai Asymp.Sig. (2-tailed)
didapatkan hasil sebesar 0,000 yang berarti <0,005 yang menunjukkan bahwa ada
pengaruh signifikan terapi dzikir terhadap waktu pulih sadar pasien pasca general
anestesi.
Kesimpulan: ada pengaruh pemberian terapi dzikir terhadap waktu pulih sadar
pasien pasca General Anestesi di RS Paru dr. Ario Wirawan Salatiga.

Stitches: Blending landscape fabric through the golden threads of spatial identity in San Riku coastline, Otsuchi, Iwate, Japan
No full textDisaster prevention and coastal protection of Otsuchi have affected the livelihood and the daily pattern of lifestyle of the regular Otsuchian. This work represents the alternative to a typical top down prefectural level demand for a line based infrastructural solution to disaster prevention and creates the required importance of livelihood, culture and identity of a place over the protection structure. While in the design of such critical areas it is important to place protection of the citizens at a high level, it is also a necessity to understand the situation of each city as different from each other. In this way, the genius loci of a place is founded. Along the San Riku coastline where the tsunami and earthquake hit the hardest due to the landscape features and the proximity to the epicenter the government has set a list of top down governed structures that have impacted the urban fabric of the city, This document looks at one of these towns “Otsuchi” and how alternate solutions based on the historical and landscape features of the district can help create landscapes of livelihood for the citizens. Otsuchi among many other Japanese cities faces the issue of a shrinking population due to a lack of economy, a lack of education in the rural areas and a lack of opportunities. The design document also looks at how Identity crisis in a Rias coastline/ Aditya Athreya Rao/ TU Delft 1 landscape can create a set of cyclical opportunities for the people to develop their town responsibly and sustain-ably as they see fit. Landscape design seeks to provide opportunity to the stakeholders to further create, it provides the platform for this creation and the thesis looks at ideas and solutions on ways this can be done.

Evaluating model free policy optimization strategies for non linear systems
No full textThe Iterative Linear Quadratic Regulator (ILQR), a variant of Differential Dynamic Programming (DDP) is a tool for optimizing both open-loop trajectories and guiding feedback controllers using dynamics information that can be inferred from data. This technique assumes linear dynamics and quadratic cost functions and improves the control policy iteratively until convergence. We demonstrate the capabilities of this framework in designing controllers for regulating both natural and custom behavior on a simple pendulum, the primitive non linear system. The method's assumptions limit its validity to smaller regions of the state space. Direct Policy Search methods use Reinforcement Learning to develop controllers for such scenarios. Nevertheless, these methods require numerous samples to generate an optimal policy and often converge to poor local optima. Guided Policy Search (GPS) is a new technique that optimizes complex non-linear policies, such as those represented through deep neural networks, without computing policy gradients in high dimensional parameter space. It trains the policy in a "supervised" fashion using numerous locally valid controllers produced by ILQR. GPS provides appealing improvement and convergence guarantees in simple convex and linear settings and bounds the error in a non-linear setting. We apply Guided Policy Search to generate control policies for locomotion of a tensegrity robot, producing closed-loop motion that could not be achieved with previous methods.M.S.Includes bibliographical referencesby Aditya H.
