Invasive Eurasian watermilfoil data from Minnesota lake point-intercept surveys between 1995 and 2019
No full textThe data was used to develop multiple species distribution models and includes both surveyed and several selected unsurveyed lakes. Besides EWM invasion status and abundance information for all surveyed lakes, the data also provides a snapshot of various ecological lake-level covariates (such as water chemistry conditions, water temperature and surrounding land-use).The datasets uploaded describe Eurasian watermilfoil distribution and abundance across the state of Minnesota. The dataset formed the basis for all the analyses in the paper referenced below.Minnesota Aquatic Invasive Species Research Center (MAISRC)Thomas, Shyam. (2021).

Projects - the cutting edge for development
Get PDFA developing country like India is generally faced with the problem of a rapidly
growing population coupled with the pressure on the arable lands .. The rapid growth of
population has created problems of unemployment and under employment in such countries.
An underdeveloped country suffers from a chronic deficiency of capital resources. The
capital per capita is very low to the tune of $350. It is the opinion of most demographers
that population pressures are like to increase still further in future in the under developed
countries. As such it become necessary to step up the rate of development in order to
outstrip the rate of population increase
Entropy and Galilean invariance of lattice Boltzmann theories
No full textA theory of lattice Boltzmann (LB) models for hydrodynamic simulation is developed upon a novel relation between entropy construction and roots of Hermite polynomials. A systematic procedure is described for constructing numerically stable and complete Galilean invariant LB models. The stability of the new LB models is illustrated with a shock tube simulation

Fisheries Project Formulation and Management
Get PDFProject formulation is an important part of entrepreneurship
development. Fisheries sector, hosting a gamut of entrepreneurship venture, requires technical know-how in project formulation and management. Keeping this in mind, my colleagues Mr. Shyam S. Salim, Scientist and Dr. R. S. Biradar, Principal Scientist of Fisheries Informatics,
Technology Evaluation and Transfer Division of this Institute have written a course manual on "FISHERIES PROJECT FORMULA TlON AND MANAGEMENT' in a simple and systematic manner to cater to the requirements and
expectations of students of fishery science. The manual contains basic concepts and applications, which are necessary to understand and practice the subject
Set Membership with Two Classical and Quantum Bit Probes
Get PDFWe study the classical and quantum bit-probe versions of the static set membership problem : Given a subset, S (|S| ≤ n) of a universe, (|| = m ≫ n), represent it as a binary string in memory so that the query "Is x in S?" (x ∈ ) can be answered by making at most t probes into the string. Let s_{A}(m,n,t) denote the minimum length of the bit string in any scheme that solves this static set membership problem. We show that for n ≥ 4
s_A(m,n,t = 2) =
(m^{1-1/(n-1)}) (if n = 0 (mod 3));
(m^{1-1/n}) (if n = 1,2 (mod 3));
(m^{6/7}) (if n = 8,9).
These bounds are shown using a common scheme that is based on a graph-theoretic observation on orienting the edges of a graph of high girth. For all n ≥ 4, these bounds substantially improve on the previous best bounds known for this problem, some of which required elaborate constructions [Mirza Galib Anwarul Husain Baig and Deepanjan Kesh, 2020]. Our schemes are explicit. A lower bound of the form s_A(m,n,2) = Ω(m^{1-1/⌊{n/4}⌋}) was known for this problem. We show an improved lower bound of s_A(m,n,2) = Ω(m^{1-2/(n+3)}); this bound was previously known only for n = 3,5 [Mirza Galib Anwarul Husain Baig and Deepanjan Kesh, 2020; Mirza Galib Anwarul Husain Baig et al., 2019; Mirza Galib Anwarul Husain Baig and Deepanjan Kesh, 2018; Mirza Galib Anwarul Husain Baig et al., 2019; Mirza Galib Anwarul Husain Baig and Deepanjan Kesh, 2020].
We consider the quantum version of the problem, where access to the bit-string b ∈ {0,1}^s is provided in the form of a quantum oracle that performs the transformation _b: |i⟩ ↦ (-1)^{b_i} |i⟩. Let s_Q(m,n,2) denote the minimum length of the bit string that solves the above set membership problem in the quantum model (with adaptive queries but no error). We show that for all n ≤ m^{1/8}, we have s_{QA}(m,n,2) = (m^{7/8}). This upper bound makes crucial use of Nash-William’s theorem [Diestel, 2005] for decomposing a graph into forests. This result is significant because, prior to this work, it was not known if quantum schemes yield any advantage over classical schemes. We also consider schemes that make a small number of quantum non-adaptive probes. In particular, we show that the space required in this case, s_{QN}(m,n = 2,t = 2) = O(√m) and s_{QN}(m,n = 2,t = 3) = O(m^{1/3}); in contrast, it is known that two non-adaptive classical probes yield no savings. Our quantum schemes are simple and use only the fact that the XOR of two bits of memory can be computed using just one quantum query to the oracle
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Criteria for Crack Nucleation in Polycrystalline Ice
No full textA theoretical analysis of crack nucleation in isotropic polycrystalline ice due to the elastic anisotropy of the constituent crystals has recently been presented by Shyam Sunder and Wu [1]. Subsequently, Shyam Sunder and Nanthikesan [2] have analyzed crack nucleation in polycrystalline ice that is isotropic but porous. The singularity of the stress concentrations near a grain boundary facet junction provides the mechanism for inducing microcrack precursors, if similar nuclei do not already exist. The total stress field is obtained by linearly superposing the microstructural stress field created by the elastic anisotropy mechanism on the applied stress field. Assuming plane stress conditions, the analysis of the nucleation stress is based on a solution to the problem of an extending precursor in a combined stress field including the effects of Coulombic frictional resistance. In the earlier papers, the local material resistance is characterized in terms of a critical value for the maximum principal tensile stress, MPTS, (Erdogan and Sih [3]). This paper compares the nucleation stresses for uniaxial and biaxial loading conditions obtained previously with those obtained from the use of a critical strain energy density, SED, factor (Sih [4]) to characterize the local material resistance. The results, synthesized into biaxial nucleation surfaces, are compared with the limiting tensile strain, LTS, criterion of Shyam Sunder and Ting [5]. The critical precursor orientation and the incipient growth direction for the two models are also compared.</jats:p
