Decentralized spectrum allocation schemes for cognitive radio networking
No full textThis thesis presents simulation and an experimental investigation of a decentralized spectrum allocation algorithm for secondary user co-existence in a cognitive radio network. Conventional centralized approaches use a Base Station (BS) or a centralized server with a global view of spectrum availability to carry out spectrum allocation. To keep this global view updated in real-time requires significant amount of signaling between the users and the BS, requiring additional spectrum. On the other hand, a decentralized spectrum allocation has the advantage of low-overhead for control information signaling and is typically more appropriate for ad-hoc network deployments. Various frameworks for decentralized resource allocation have already been proposed (Game theoretic framework, markov decision theoretic framework etc.). However, a full system implementation of any such technique has not been attempted. Inspired by the TCP congestion control mechanism, an Additive Increase Multiplicative Decrease (AIMD) based decentralized spectral allocation algorithm is proposed. It leads to a network-level fairness and efficient spectral usage in a cognitive radio network. A network consisting of only secondary users is considered for this problem and each secondary user uses a Non-Contiguous OFDM (NC-OFDM) transceiver system for data transmission. The GNU Radio-USRP2 cognitive radio platform is used for implementation purposes. This thesis also presents an experimental evaluation of an active interference suppression scheme used along with NC-OFDM to enhance the spectral quality of the transmitted waveform and, thereby, improving the overall spectral efficiency of the network. The RF transmission quality of the IA-PFT based NC-OFDM transmission using GNU Radio-USRP2 has been verified with reference to simulation results. Some system level throughput measurement results for Primary- Secondary Co-existence experiments are also discussed in the thesis. The functioning of the decentralized spectrum allocation algorithm has been validated using MATLAB simulations.M.S.Includes bibliographical referencesby Srinivas Pinagapan
Characterization and evolution of complex 3D materials by digital image analysis and correlation
No full textThe aim of this thesis is to present a methodology to utilize spatial density visualization capabilities of X-Ray Microtomography (μCT) to characterize, and to capture the deformation in complex materials. μCT is a versatile technique, which has been used to non invasively visualize, investigate and quantitatively analyze materials and works on the principle of attenuation of X-Rays as they pass through them. In the first part of this dissertation, we have attempted to employ this 3D imaging technique to study the influence of local density variations along the length and width of a roller compacted Micro Crystalline Cellulose (MCC) ribbon on the local ribbon strength which in turn, potentially alter the mechanical properties (such as tensile strength and hardness) of its end product - a solid pharmaceutical dosage form. Density variations in three cases of ribbons produced a) with no lubrication b) by including Magnesium Stearate lubricant in the excipient and c) by lubricating rolls and screws have been investigated. Heckel and elastic recovery analysis indicate that the local density variations in the roller compacted ribbons drastically impact the mechanical properties of the solid dosage form. The rest of this dissertation involves the study of micromechanical behavior of open-cell solid foams. Metallic foams are cellular materials of very low densities in comparison to their parent material and are capable of large deformations owing to cellular collapse. Our understanding of their mechanical behavior is restricted to their heterogeneous deformation under uniaxial compression because of its architecture. Even though high speed photography combined with Digital Image Correlation techniques, capture the whole field strain map, they are limited by their capacity to visualize the surface deformation. Since the boundary conditions inside the volume of the sample are different, the surface deformation may or may not be a representative of the deformation pattern in the complete volume of the sample. Assuming plane strain along the direction of applied uni-axial deformation, the full field strain in the sample volume is measured by Digitally Correlating average images extracted from volumetric μCT data (which capture spatial material information from a thin section of the sample volume) with a similar successive image through progressive steps of applied deformation. Strain fields at slices at the surface and those at the interior are compared. It has been found that regions closer to the free surface are susceptible to higher deformation values in comparison to the core. A foundation has been created to expand this methodology to capture the out of plane deformation in the entire volume.M.S.Includes bibliographical referencesby Srinivas Iye
Preventing ethnic violence with local capacities: lessons from civil society in India
No full textThe research questions are: How have civil society organizations (CSOs) in India prevented Hindu-Muslim riots? And what can these experiences teach us about building local capacities around the world to prevent ethnic riots? This study seeks to elucidate patterns of institutional identities, relationships, and micro-level processes that can improve CSOs‘ ability to prevent ethnic riots. The Hindu-Muslim conflict offers a specific case from which a general framework for CSO interventions is induced. There is little systematic comparison of successful micro-level processes of riot prevention. Anecdotes of CSO successes do not offer guidance on why they were successful and if they are relevant for other CSOs in other places. Understanding these successes and challenges in a comparative framework, rather than as isolated events, is not only important for developing preventive mechanisms in India, but it can also offer lessons for increasing capacities for prevention in other multi-ethnic societies. Interviews, based on questionnaires that were developed, were the main form of data gathering. Two types of comparisons was done: 1) comparing successful and unsuccessful cases of prevention between organizations in a city, and 2) comparing successful cases in different cities and noting similarities and differences in institutions and strategies. In addition to specific lessons detailed in the thesis, the following broad principles were uncovered as important for effective prevention. 1) Regular contact with potential victims and leaders in communally sensitive communities is the foundation for prevention. 2) Development CSOs in the field are best placed to conduct operational prevention because their work in communally sensitive areas has earned them the trust of residents, they have detailed knowledge of the area, and have more funding. However, peacebuilding organizations have the expertise on conflict prevention, and thus should collaborate with development organizations. 3) Relationships with police will impact the effectiveness of intervention. 4) CSOs should create operational prevention networks with CSOs and build relationships with actors in the community in order to increase their power to lobby political authorities during crises, increase resources for prevention, and to scale up the impact of their activities to affect a wider area.Ph.D.Includes bibliographical referencesIncludes vitaby Srinivas Vaitl
IMPROVEMENT OF BEARING CAPACITY OF SANDY SOIL BY GROUTING
No full textThe constructional activities in the coastal areas often demand deep foundations because of the poor engineering properties and the related problems arising from weak soil at shallow depths. The very low bearing capacity of the foundation bed causes shear failure and excessive settlements. Further, the high water table and limited depth of the top sandy layer in these areas restrict the depth of foundation thereby further reducing the safe bearing capacity. Grouting, which has several applications in the field of civil engineering, was once considered as a mysterious operation. The effectiveness of grouting requires a lot of understanding, skill, meticulous attention and an intuitive perception Grout is injected under pressure into the material to be grouted until it fills the desired volume of material around the hole or until the maximum specified pressure is attained and a specific minimum grout flow is reached. the strength improvement of loose sandy soils through cement grouting Permeation grouting is a simple method of ground improvisation technique which helps to stabilize the loose soil stratum. Permeation grouting is a process of filling the pores in the soil with the cement slurry and improves the engineering properties of the possible solutions to the foundation problems by improving the properties of soil at shallow depths by using sodium silicate. The shear strength parameters in the loose and medium dense state of the soil are investigated by plate load test on the grouted soil sample by determining the correlation between load and displacement on the grouted medium

Physical properties of amorphous Al-Gd-transition metal alloys
No full textAmorphous alloys of the composition Al65Gd15Cu20 and Al1Gd1Fe1 have been prepared by rapid quenching from the melt. The alloys have been studied by X-ray diffraction, thermal analysis and SQUID magnetization methods. Thermal analysis results show crystallization temperatures of 647 and 945 K for Al-Gd-Cu and Al-Gd-Fe, respectively. For Al-Gd-Cu, magnetization measurements show Curie-like behaviour with a localized Gd magnetic moment of 8.0mu(B). Magnetic measurements of Al-Gd-Fe show conventional ferromagnetic behaviour. The Curie temperature is found to be 275 K and a saturation magnetization of 124 emu/g is measured at 4.2 K in an applied magnetic field of 1 T.PT: J; CR: DUNLAP RA, 1989, PHYS REV B, V39, P4808 DUNLAP RA, 1990, J PHYS CONDENS MATT, V2, P4315 DUNLAP RA, 1990, UNPUB HE Y, 1988, SCIENCE, V241, P1640 INOUE A, 1981, J MATER SCI, V16, P1989 INOUE A, 1988, JPN J APPL PHYS, V27, P1796 INOUE A, 1988, JPN J APPL PHYS, V27, L1579 INOUE A, 1988, JPN J APPL PHYS, V27, L479 OHANDLEY RC, 1991, HDB MAGNETIC MATERIA, V6, P453 SRINIVAS V, 1990, J APPL PHYS, V67, P5879 SUZUKI RO, 1985, J MATER SCI, V18, P1195 YEWONDWOSSEN M, 1990, THESIS DALHOUSIE U YEWONDWOSSEN M, 1992, J PHYS-CONDENS MAT, V4, P461; NR: 13; TC: 1; J9: J NON-CRYST SOLIDS; PN: Part 1; PG: 3; GA: LC964Source type: Electronic(1
