Distributed optimization on a wireless sensor network testbed
No full textThe focus of this thesis is to implement various distributed optimization algorithms on a physical wireless sensor network. Distributed optimization refers to optimization of some global function which is not completely known to any single node in a communication network. The global function is some combination of local functions that are available at each node. Therefore the objective is for all nodes to achieve consensus on the global optimum given only local information and communication with neighbors.
Algorithms from the literature that address this problem in different set- tings are introduced, focusing on an incremental subgradient-based algorithm and a broadcast, gossip-based algorithm. These algorithms are applied to lo- calize a light source. This localization problem is formulated as a distributed optimization problem in which the global optimum is the true location of the source, and the local information is comprised of light intensity measurements at each node. Simulation results and results from physical implementations on the testbed are presented for the two different approaches. A modified version of the broadcast algorithm is also presented, and is shown to be supe- rior to the unaltered algorithm in certain settings via simulation and testbed results.Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-05-01The student, Neeraj Venkatesan, accepted the attached license on 2015-04-23 at 19:16.The student, Neeraj Venkatesan, submitted this Thesis for approval on 2015-04-23 at 19:21.This Thesis was approved for publication on 2015-04-24 at 09:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #8071 on 2015-07-22 at 14:18:45Made available in DSpace on 2015-07-22T22:33:52Z (GMT).

Comparison of anti-inflammatory efficacy of lercanidipine and Tanacetum parthenium with indomethacin in rats
No full textBackground: Inflammation can be classified as either acute or chronic. NSAIDs are the most commonly prescribed drugs worldwide, and mostly have adverse effects. Lercanidipine a CCB of (DHPs) blocks the mediators of inflammation and has additional anti-inflammatory potential. Tanacetum parthenium (Feverfew) extracts have also shown its anti-inflammatory effects in experimental studies. It was decided to study anti-inflammatory effects of Lercanidipine and Tanacetum parthenium which was compared with Indomethacin. The present study was aimed to evaluate and compare the anti-inflammatory effect of lercanidipine and Tanacetum parthenium with Indomethacin in rats.Methods: The study was conducted in the department of Pharmacology UPUMS, Saifai after getting approval from IAEC.A total of 24 animals divided into 4 groups of six (n=6) animals each group were used, and the anti-inflammatory effects of both drugs were evaluated by Carrageenan-induced Paw Edema Model by digital Plethysmometer in rats, drug administration was with the same frequency.Results: The result of the present study had shown that lercanidipine produced anti-inflammatory effect compared to Indomethacin, while its efficacy in reducing paw edema was better at 1st hour, 48 and 72 hours while at 2nd hour and 3rd hour Indomethacin had better efficacy. Tanacetum parthenium also decreased paw edema at 2nd, 3rd, 48 and 72 hour while at 1st hour no effect was seen. However, at 72 hours, shown good efficacy compared to lercanidipine and Indomethacin.Conclusions: Lercanidipine could be a promising anti-inflammatory drug in reducing the inflammation and edema. However, herbal drug (Tanacetum parthenium) has shown anti- inflammatory efficacy when compared with Indomethacin. Both drugs were found safe during our study.</jats:p
Effect of Food Subsidies on Micronutrient Consumption
No full textIn this article, we study the effect of an exogenous increase in wheat and rice price subsidy to poor families resulting from a targeted food price subsidy program in India called the Targeted Public Distribution System (TPDS) on micronutrient intake in low-income families. Descriptive results show that wheat and rice have one of the lowest micronutrient density scores, suggesting that these are poor suppliers of micronutrients. Empirical analysis suggests that the increase in subsidy amount of Rs. 15-18 resulting from the TPDS expansion lowered calcium intake by 12-14 percent and had negligible to small (often negative) effects on the consumption of most micronutrients.Peer reviewe
Culture, labor supply, and fertility across immigrant generations in the United States
No full textRecent immigration to the United States and other developed nations has increasingly been from countries that have relatively traditional gender norms. This study uses data from the Current Population Survey for 2000–14 to investigate how source-country gender norms influence the labor supply and fertility of married women across immigrant generations in the US. It finds that immigrants’ and descendants’ labor supply and fertility are associated with the female-to-male labor force participation ratio and total fertility rate in the source country; importantly, the association declines across successive generations. Husbands’ source-country characteristics are also associated with the labor supply and fertility of immigrant women. These findings indicate evolution and assimilation of traditional gender norms in the long run.Peer reviewe
Comparative study to evaluate efficacy and safety of topical alcaftadine 0.25% versus topical olopatadine 0.2% eye drops in patients with allergic conjunctivitis in a tertiary care teaching hospital, Haldwani
No full textBackground: Ocular component is the most prominent and disabling feature of allergy leading to symptoms like itching and watering of eyes causing significant irritation. Allergic conjunctivitis (AC) is one of the most common ocular conditions affecting adult and pediatric patients that requires treatment by ophthalmologists. AC and its debilitating symptoms like itching, watering of eyes and ropy discharge have interfered their day to day activities, difficulty in concentrating in work and has adversely affect the quality of life. Aim and objectives were to study and compare the efficacy and safety profile of topical alcaftadine versus topical o lopatadine eye drops in patient with AC. To compare efficacy of topical alcaftadine versus topical olopatadine eye drops, to observe adverse drug reaction of both eye drops.
Methods: A prospective, open labelled comparative hospital based study was conducted in the department of ophthalmology in collaboration with department of pharmacology GMC Haldwani, Uttarakhand. Patients with AC (n=120) were randomised into two groups: Alcaftadine 0.25% eye drop and olopatadine 0.2% eye drop once daily. Patients were assessed on the first day 2nd week and 4th week. Reduction in total severity score and efficacy was measured in both treatment groups. Safety was assessed by observing adverse drug reaction using WHO UMC Causality assessment scale and modified Hartwig Siegel’s severity scale.
Results: A trend in significant improvement in patients treated with alcaftadine eye drop in comparison to patients treated with olopatadine eye drop at both second week and fourth week follow up. No adverse effects were reported with either eye drops in both groups.
Conclusions: Alcaftadine eye drop showed higher efficacy than olopatadine eye drop in relieving signs and symptoms of AC. Both treatment groups were found to be safe and effective
The infrastructural space of appearance : the re-formed public library
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Architecture, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Vita.Includes bibliographical references (p. 219-227).This thesis examines the dilemma of the common object in a liberal pluralist society. Situating the arguments in Hannah Arendt's The Human Condition, the thesis investigates the notion of the Space of Appearance in the contemporary city as providing a common platform for exchange. This Space of Appearance is conceived of through the linking of two public and democratic infrastructures -- mass transport lines and the public library. By symbiotically linking the two infrastructures, a space for action and speech emerges that creates concern for the collective object, thereby affirming the reality provided by the public realm. Using Toronto, Ontario as a case study of multicultural pluralism, the thesis examines the location of Southern Ontario in North America as a precursor to Toronto's multicultural success. From here, the study zooms into a specific site in the center of Toronto entitled "CityPlace." CityPlace is an island formed and bounded through massive infrastructural separation, while simultaneously situated at the convergence of the city's flows. It is this "neither zone" of both Southern Ontario, and more locally, CityPlace that is believed to strengthen its ability to embrace pluralism. An urban design proposal for this foreign island of CityPlace investigates the common object in pluralism at the scale of the city. Lastly, this thesis investigates the common object in pluralism at the scale of architecture, namely the public library. through situating the discourse of the library in a historic lineage, the current dilemmas of library design are extracted. A new typology is developed which directly addresses these problems, the CityPlace island, and Arendt's notion of plurality.(cont.) As the medium of library information increasingly changes to non-spatially bound forms, the primary role of the new typology is repositioned as its ability to provide a common meeting ground for the city. Through an investigation of pluralism, the thesis proposes an Infrastructural Space of Appearance that provides a collective platform for exchange at the scale of the city and building, in the liberal pluralist city of Toronto.by Neeraj Bhatia.S.M
Quantifying and improving the availability of cooperative cluster-based internet services
No full textMuch research has shown that cluster-based servers can substantially increase performance when nodes cooperate to share and globally manage their resources. In this paper, we apply a quantification methodology to show that this performance increase has a corresponding substantial cost in availability. Specifically, we show that a sophisticated cluster-based web server gains a factor of 3 in performance when nodes cooperate to balance load and jointly manage their memories, but also suffers an increase in unavailability of a factor of 10. We then show how this web server can be augmented with Commercial Off-The-Shelf (COTS) components embodying a small set of high-availability techniques to regain the lost availability. Among other interesting observations, we show that the application of multiple high-availability techniques, each implemented independently in its own subsystem, can lead to inconsistent recovery actions. We also show that a novel technique called Fault Model Enforcement can be used to resolve such inconsistencies. Augmenting the server with these techniques led to a final predicted availability of close to 99.99.Technical report DCS-TR-51
Evaluating the Impact of Communication Architecture on the Performability of Cluster-Based Services
No full textWe consider the impact of different communication architectures on the performability (performance + availability) of cluster-based servers. In particular, we use a combination of fault-injection experiments and analytic modeling to evaluate the performability of two popular communication protocols, TCP and VIA, as the intra-cluster communication substrate of a sophisticated Web server. Our analysis leads to several interesting conclusions, the most surprising of which is, under the same fault load, VIA-based servers deliver greater availability than TCP-based servers. If we assume higher fault rates for VIA-based servers because the underlying technology is more immature and programming model more complex, we find that packet errors or application faults would have to occur at approximately 4 times the rate in TCP-based servers before their performability become the same. We also use results from the study to make suggestions for the design of a high-performance and robust communication layer for highly available cluster-based servers. More specifically, we argue that it should use messaging (not a byte stream), single-copy transfers, pre-allocated channel resources, and match the network fabric's fault model.Technical report DCS-TR-49
