Designing of Modified Area Efficient Square Root Carry Select Adder(SQRT CSLA)
No full textIn the design of Integrated Circuits, The necessity of portable systems is increasing an area occupancy plays a vital role. Square Root Carry Select Adder (SQRT CSLA) is one of the fastest adders which is used in this data-processing processor to perform fast arithmetic functions. In this paper, an area-efficient square root carry select adder(SQRT CSLA design) by sharing Common Boolean logic term (CBL) is proposed The modified architecture has been developed using Binary to Excess-1 converter (BEC). Based on this modification 8-, 16-, 32-, and 64-b square-root CSLA (SQRT CSLA) architecture have been developed by using CBl. The proposed design has reduced area as well as power,but in this we study only for area with a slight increase in the delay
Architecture of a programmable system-on-chip platform for flexible radio processing
No full textThe emergence of multiple radio access technologies (RATs) and their continuous evolution, is driving the need for programmable radio processing. Programmable radio devices with run-time flexibility and resource virtualization features will not only enable faster time-to-market, longer lifetime of devices, and universal connectivity, but also act as building blocks for advanced wireless technologies of adaptive and cognitive radios. These requirements have forced a shift from the traditional ASIC approach. However, most existing flexible solutions are based on either fully software-defined or software-controlled approaches that lack the power efficiency, performance and determinism (for real-time constraints) needed for wireless processing. In this thesis, we propose a programmable multi-processor system-on-chip (SoC) platform architecture based on a novel Virtual Flow Pipelining (VFP) framework that aims at striking a balance between flexibility (as provided by SDR) and performance (as provided by ASICs). The key highlights of this concept are a simple task-level programming model for provisioning protocol flows, and the use of dedicated hardware-based OS-like support for controlling their run-time execution. We present the evolution of a clustering-based organization for the SoC with distributed-shared controllers. Clustering along with an inherent architectural support for message passing provides a balance between scalability and hardware overhead. Shared controllers with a pipelined microarchitecture and a separate interconnect for control messaging are designed for low hardware complexity and high performance. The proposed architecture is evaluated by creating a bit- and cycle-accurate model in synthesizable register-transfer-level (RTL). It has been built into a virtual platform for 802.11a transmitter, which has successfully executed single and multiple flows for rates of 6, 12 and 24 Mbps. This thesis also presents a characterization and analysis of the architecture to provide key implications such as control overhead for different task sizes, its impact on cluster size etc.M.S.Includes bibliographical referencesby Onkar Sarod
Abfraction Lesions: Analyzing the cause by identifying biological and lifestyle similarities
No full textAbfraction lesions are non-carious (not caused by decay), wedge-shaped indentations near the gumline that expose the sensitive dentin under the protective enamel (Sarode and Sarode, 2013). A clear understanding of the contributors to abfraction formation would have a major impact on clinical dentistry, potentially informing interventions to prevent these lesions. Knowing the causes of abfractions would also benefit forensic anthropology and bioarchaeology, since dental structures are widely used to determine aspects of a deceased individual’s identity, including their age, sex, population affinity, habits, and general lifestyle. However, there little consensus on the etiology of abfractions among the various disciplines affected (Jakupovic et al., 2014; Nascimento et al., 2016)
Color Image Compression Using Vector Quantization and Hybrid Wavelet Transform
No full textAbstractThis paper presents simpler image compression technique using vector quantization and hybrid wavelet transform. Hybrid wavelet transform is generated using Kronecker product of two different transforms. Image is converted to transform domain using hybrid wavelet transform and very few low frequency coefficients are retained to achieve good compression. Vector quantization is applied on these coefficients to increase compression ratio significantly. VQ algorithms are applied on transformed image and codebooks of minimum possible size 16 and 32 are generated. KFCG and KMCG are faster in execution and beats performance of LBG algorithm. KFCG combined with hybrid wavelet transform gives lowest distortion and acceptable image quality at compression ratio 192
Public participation in urban development: a case Nagpur city
No full textThe Oxford dictionary defines participation as "to have a share in" or "to take part in", thereby emphasizing the rights of individuals and the choices that they make in order to participate. Increased participation is needed to conquer an imbalance in access to information and to influence decisions. Vigorous citizen participation programs can benefit managing agencies by reducing conflicts, by improving public understanding and by helping managers assess public attitudes. Urban Planning
is an example of the need for community participation, for it affects everyone. The idea of an ideal community Participation can be traced back to Jean Jack Rousseau. As a reaction to his experience of the urban public of the eighteenth century, Rousseau developed a political philosophy based on the ideal community. In this philosophy Rousseau dreams of: A society where all people are aware of existing opportunities for effective participation in decision making, they believe participation is worthwhile, and they participate actively in a society that is bound together by collective decisions. In this society, the role of participation is exactly that men “not law” should rule, and therefore be ruled by the logic operation of the political situation that they themselves have created. According to Dr. David Harvey, author of the book ‘Rebel Cities: From Right to the City to Urban Revolution’, the role of the planner is to facilitate the provision of information on basic decision-making structure to open up the public space not just in the physical sense but as a public sphere in dialogue and negotiation for the empowerment of the general citizen. The study area selected for the purpose of this thesis is Nagpur City, in Maharashtra, India. Nagpur is governed by Nagpur Municipal Corporation since 1951, and Nagpur Metro Region Development Authority (NMRDA), formerly, Nagpur Improvement Trust is the Urban Development Authority. The area of Nagpur is 217.6 sq km. Nagpur is divided into 10 zones which are further divided
into 136 wards for administrative purposes. This thesis is a study of the citizen engagement strategies employed for the Smart Cities mission in Nagpur city. This thesis intends to explore the potential of Public Participation in Urban development in the contemporary Indian scenario, by understanding the process of communication between the citizens and authorities, identifying barriers to effective two-way communication and developing strategies to overcome such barriers
Opportunity cost analysis of android smartphones' permissions
No full textThis thesis provides the opportunity cost for reading androids permission model. We investigate the opportunity cost for users and an example nation (United States), if people would actually read these permission screens during installation time.While the Federal Trade Commission and reserachers try to protect users’ privacy and to improve their comfort level with mobile applications, users still remain unaware of these changes. Users are given a choice to overview the permissions an app would use and have to make an on the spot decision to accept these and move forward with the installation. In this research we project the time required by an average user if they were to read the permissions and compute the monetary value of that time in different situations. An average user may spend half an hour in overviewing permission screens bearing maximum opportunity cost of 3 based on whether it was read at work or leisure. Other than this, if the users decide to read the details of these permissions as well, they will spend more time and hence bear more cost. Reading permissions with details would require users to spend two and half hours annually with a maximum cost of 13. An entire nation (United States) would have to invest a minimum of 6 billion, in reading permissions.M.S.Includes bibliographical referencesby Swapnil Sarod
Thrombotic thrombocytopenic purpura: 24 Years of experience at the American University of Beirut Medical Center
No full textThrombotic thrombocytopenic purpura (TTP) is a hematological syndrome defined by the presence of thrombocytopenia and microangiopathic hemolytic anemia without a clinically apparent etiology. Patients may also suffer from fever in addition to neurological and renal impairment. Treatment should be initiated as soon as possible, otherwise this rare disease can be fatal. The main treatment options include therapeutic plasma exchange, fresh frozen plasma infusion, and adjuvant agents such as steroids and antiplatelet drugs. A search of patient records was carried out at the American University of Beirut Medical Center looking for patients who developed TTP over a 24-year period extending from 1980 to 2003. Relevant information was collected and analyzed. A total of 47 records were found. All presented with anemia and thrombocytopenia, 83percent had neurological symptoms, 61.7percent had fever and 34percent had renal impairment. All patients were treated with a multimodality regimen including therapeutic plasma exchange, FFP infusion, steroids, antiplatelet agents, vincristine and others. 38 (81percent) cases achieved complete remission. Out of these, 12 (31.6percent) relapsed and responded to treatment. Patients who did not receive plasma exchange were more likely to relapse (P = 0.032). A second relapse was observed in 6 cases. The overall mortality rate from TTP over 24 years was 21.3percent. TTP remains a fatal disease. A high index of suspicion should, therefore, always be present. Treatment options should be further developed and patients should directly be referred to tertiary care centers. © 2004 Wiley-Liss, Inc.ANSELL J, 1978, ANN INTERN MED, V89, P647; ASADA Y, 1993, JPN J CLIN MED, V51, P159; ASTER RH, 1985, NEW ENGL J MED, V312, P985, DOI 10.1056-NEJM198504113121510; ATKINSON K, 1983, BRIT J HAEMATOL, V54, P59, DOI 10.1111-j.1365-2141.1983.tb02067.x; BELL WR, 1991, NEW ENGL J MED, V325, P398, DOI 10.1056-NEJM199108083250605; Bennett CL, 2000, NEW ENGL J MED, V342, P1773, DOI 10.1056-NEJM200006153422402; BUKOWSKI RM, 1977, BLOOD, V50, P413; BYRNES JJ, 1977, NEW ENGL J MED, V297, P1386, DOI 10.1056-NEJM197712222972507; BYRNES JJ, 1986, CLIN HAEMATOL, V15, P413; Chang JC, 1996, AM J HEMATOL, V53, P11, DOI 10.1002-(SICI)1096-8652(199609)53:111::AID-AJH33.0.CO;2-8; Dervenoulas J, 2000, ANN HEMATOL, V79, P66, DOI 10.1007-s002770050012; Eldor A, 1998, BAILLIERE CLIN HAEM, V11, P475, DOI 10.1016-S0950-3536(98)80062-0; Furlan M, 1998, NEW ENGL J MED, V339, P1578, DOI 10.1056-NEJM199811263392202; Furlan M, 1996, BLOOD, V87, P4223; Furlan M, 1997, BLOOD, V89, P3097; HARKNESS DR, 1981, JAMA-J AM MED ASSOC, V246, P1931, DOI 10.1001-jama.246.17.1931; HAYWARD CPM, 1994, ARCH INTERN MED, V154, P982, DOI 10.1001-archinte.154.9.982; Lara PN, 1999, AM J MED, V107, P573, DOI 10.1016-S0002-9343(99)00286-7; MachPascual S, 1996, AM J HEMATOL, V52, P310, DOI 10.1002-(SICI)1096-8652(199608)52:4310::AID-AJH113.0.CO;2-H; McCarthy LJ, 2002, THER APHER, V6, P2, DOI 10.1046-j.1526-0968.2002.00363.x; Moake J.
