Relationships in works Poet Na. Muthukumar
No full textRelationships with others or similar groups in society in the youth of everyone's life provide many experiences. Home situations, the sense of safety and care available to parents are significant in this development. For the youth, the family provides the protective features of food, clothing, shelter and love. It is desired to give himself priority and freedom in homes. It is learnt that children's attitudes also develop according to the upbringing of their parents at home. Human behaviors are developed and regulated by social units in which human interaction sits. In this way, relationships are often the state of family relationships and the state of co-relationships of society. It is the urge to live together, the urge to depend, to do so, and to take the lead in the process of conception and co-operation. This article is a demonstration of the nature of such relationships through the works of poet N. Muthukumar

Complete and efficient methods for supporting side effects in independent/restricted and-parallelism
No full textIt has been shown that it is possible to exploit Independent/Restricted And-parallelism in logic programs while retaining the conventional "don't know" semantics of such programs. In particular, it is possible to parallelize pure Prolog programs while maintaining the semantics of the language. However, when builtin side-effects (such as write or assert) appear in the program, if an identical observable behaviour to that of sequential Prolog implementations is to be preserved, such side-effects have to be properly sequenced. Previously proposed solutions to this problem are either incomplete (lacking, for example, backtracking semantics) or they force sequentialization of significant portions of the execution graph which could otherwise run in parallel. In this paper a series of side-effect synchronization methods are proposed which incur lower overhead and allow more parallelism than those previously proposed. Most importantly, and unlike previous proposals, they have well-defined backward execution behaviour and require only a small modification to a given (And-parallel) Prolog implementation
Achieving progressive fine granularity scalable coding in H.26L
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaves 60-61).Issued also on microfiche from Lange Micrographics.Fine granularity scalable (FGS) coding and progressive fine granularity scalable (PFGS) coding are novel scalable video schemes which are ideally suited for streaming multimedia over networks with varying bandwidth, network conditions and receiver capabilities. The FGS coding scheme has already been implemented in the MPEG-4 standard and has shown good performance in streaming applications when compared to traditional scalable video schemes. H.26L, the long term version of H.263, is an upcoming standard which performs better than MPEG-4 over a wide range of bit rates. But this standard does not currently have any scalability feature in it which makes it suitable to be used for streaming multimedia applications. The above mentioned FGS and PFGS scalable video schemes are implemented in H.26L and their performance is compared with that of the non-scalable MPEG-4 scheme. Some variations of the currently existing PFGS coding frameworks are implemented and further improvements are also proposed in this thesis
A hybrid network IDS for protective digital relays in the power transmission grid
No full textIn this paper, we propose a novel use of network intrusion detection systems (NIDSs) tailored to detect attacks against networks that support hybrid controllers that implement power grid protection schemes. In our approach, we implement specification-based intrusion detection signatures based on the execution of the hybrid automata that specify the communication rules and physical limits that the system should obey. To validate our idea, we developed an experimental framework consisting of a simulation of the physical system and an emulation of the master controller, which serves as the digital relay that implements the protection mechanism. Our Hybrid Control NIDS (HC-NIDS) continuously monitors and analyzes the network traffic exchanged within the physical system. It identifies traffic that deviates from the expected communication pattern or physical limitations, which could place the system in an unsafe mode of operation. Our experimental analysis demonstrates that our approach is able to detect a diverse range of attack scenarios aimed at compromising the physical process by leveraging information about the physical part of the power system
Apparent Molar Mass of a Polyelectrolyte in an Organic Solvent in the Low Ionic Strength Limit As Revealed by Light Scattering
No full textThe
apparent molar mass of a partially quaternized poly-2-vinylpyridines
(degree of quaternization 4.3% Q < 35%) in
1-propanol is measured by light scattering at low ionic strength (10–6 M cs –3 M) as a function of polyion repeat unit concentration
(7 × 10–5 monomol/L cm,p –2 monomol/L). No
dialysis was applied prior to measurements. The apparent molar mass
under “salt-free” conditions is smaller than the true
molar mass by an order of magnitude, while approaching the true value
at higher ionic strength. Concomitant data on the dependence of scattering
intensity on scattering wave vector show that the dilute polyelectrolyte
solutions are strongly correlated. A recent theory by Muthukumar for
light scattering of dilute polyelectrolyte solutions, developed for
correlated multicomponent systems, accounts for interchain electrostatic
correlations and regularization of polymer charge by counterion binding
isotherm. The experimental results on the relation between the apparent
and true molar masses as a function of salt concentration are compared
with the predictions of Muthukumar’s counterion adsorption
theory. Taking binding equilibrium constant as a single fitting parameter,
this theory is demonstrated to describe the experimental data as long
as the chains do not interact significantly
Management of Acidic Soils
No full textSoil acidity is a serious constraint to crop production in many regions of the world including India. Acidic
soils in India are mainly prevalent in the humid Southwestern, Northeastern and Himalayan regions (Maji
et al. 2008). They are particularly acute in the humid tropical regions that have been subjected to severe
weathering. In India, about 48 m ha out of 142 m ha of arable land are affected by acidity, of which 25
m ha have pH below 5.5 and 23 m ha have pH between 5.6 and 6.5 (Mandal 1997). Strongly acidic and
moderately acidic soils cover 6.24 m ha (1.9%) and 24.41 m ha (7.4%), respectively of the country’s total
geographic area (Maji et al. 2012). In the Northeastern region, approximately 95% of the soils are acidic
and nearly 65% have strong acidity with pH below 5.5 (Sharma and Singh 2002). Acidic soils of Odisha
account for 70% of its total geographical area (Jena 2008). A similar finding was reported in Odisha by
Nanda et al. (2008) based on the analyses of 1,219,000 soil samples. A recent study conducted by ICRISAT
found that of the 40,265 soil samples analysed, more than 80% were acidic in natur

Effect of Long-Term Tillage Practices on Soil Physico-Chemical Properties and Weed Population Dynamics in a 36-Year Old Experiment
No full textChanges to tillage practices can influence soil physico-chemical properties and weed population dynamics. Experiments were conducted in 2016 and 2017 in a 36-year long tillage experiment at Texas A&M University, College Station, TX to study the impact of tillage regimes on soil physio-chemical properties and weed population dynamics in monoculture grain sorghum (Sorghum bicolor), and weed dynamics alone in monoculture soybean (Glycine max). The tillage systems studied include conventional-tillage (CT) and no-tillage (NT). Results showed that tillage did not affect soil bulk density, total porosity, air filled porosity, water-filled pore space and volumetric water content. However, water holding capacity, soil organic carbon, and cumulative carbon mineralization were 25, 43, and 16% greater in the NT system, compared to CT, at the 0 to 5 cm soil depth. Conversely, cumulative water infiltration and CO2 emission were greater in the CT system (23.66 cm hr^–1 and 7.28 g m^–2) than NT (3.98 cm hr^–1 and 5.19 g m^–2) in 5 and 24 hrs study. The long-term tillage regimes also influenced weed population dynamics and seedling emergence in grain sorghum and soybean. Greater densities of Johnsongrass (Sorghum halepense), prostrate spurge (Chamaesyce humistrata), tall waterhemp (Amaranthus tuberculatus), henbit (Lamium amplexicaule) and shepherd’s purse (Capsella bursa-pastoris) were recorded in the NT system, compared to the CT system in both crops. The long-term NT system was characterized by greater weed diversity (Shannon-Wiener’s index, H = 0.8) and species richness (S = 6.2) compared to CT (H = 0.6; S = 4.2) in sorghum; however, no differences were found in weed species diversity in soybean. Moreover, a greater proportion of the viable seedbank was located in the top 5 cm soil depth in the NT system (24 to 96% depending on the weed species) compared to the CT system (22 to 61%). Overall, results illustrated that long-term NT practices can provide environmental benefits and are more sustainable than CT. However, growers shifting to NT practices should consider potential changes to weed population dynamics and adjust the management programs accordingly
