Scientometric Portrait of Homi Jehangir Bhabha: The Father of Indian Nuclear Research Programme
No full textQuantitative and qualitative analysis with graphic representation of the publication productivity of a scientist facilitates easy and clear perception about the work of a scientist. Bhabha’s scientific work spanned over more than three decades (1933-1967) during which he published 104 publications, which could be classified into nine fields: Interaction of Radiation with Matter (4), Quantum Electrodynamics (5), Mathematical Physics (2), Cosmic Ray Physics (18), Elementary Particle Physics (14), Field Theory (15), General Physics (2), Nuclear Physics (4) and General (40). The highest number of publications (6) were published in 1941, 1945 and 1964 respectively. The average number of publications published per year was 3.05. His productivity coefficient was 0.05 which is a clear indicates that his publication productivity was quite consistent throughout his scientific career. He was single author in 79 of his publications and the main author in 24 publications indicates that he always preferred to work himself and lead the team as ‘mentor’. Bhabha had 22 collaborators during the period. Team of research collaborators working with a successful scientist documents the sociological aspect of history of science while generating knowledge by a leader in a domain.
Bhabha became a citable author in 1937. Bhabha received 1211 citations to his 30 publications out of 104 publications. Out of 104, 74 publications did not receive any citations. Out of 74 publications, 40 publications dealt subjects mainly of general interest. Bhabha’s 86.66 percent of cited publications received their first citations within four years of their publication indicates that his publications were noticed immediately and had direct impact among the fellow researchers working all over the world. His overall citation rate was 11.64 per cited publication. The highest citations 389 were received to the domain ‘Cosmic ray physics’. The highest number of citations received were 45 in 1938. His self-citations were only 24 (1.98%) and citations by others were 1187 (98.02%). The highest self citations were six in 1946. Bhabha’s mean diachronous self-citation rate was 1.98. The highest citation rate 28.4 was to the domain ‘Quantum electrodynamics. His single authored publications have received the highest number 863 (71.26%) of citations. Bhabha’s five publications have been cited more than 100 times each. His publications have been cited by the authors working in various diverse fields like nuclear physics, mathematical physics, instrumentation, optics, geophysics and geochemistry, condensed matter physics, applied physics, electrical and electronic engineering, mechanical engineering etc., indicating a very diverse influence and impact of Bhabha’s publications. Bhabha’s publications have also been cited by the Nobel laureates like V. L. Ginzberg, Wolfgang Pauli, H. A. Bethe, M. Born, W. Bothe, E. P. Wigner, H. Yukawa, P. M. S. Blackett and C. N. Yang which is an indication of his originality of ideas and high quality of publications
Locally Recoverable Streaming Codes for Packet-Erasure Recovery
No full textStreaming codes are a class of packet-level erasure codes that are designed with the goal of ensuring recovery in low-latency fashion, of erased packets over a communication network. It is well-known in the streaming code literature, that diagonally embedding codewords of a [τ+1,τ+1-a] Maximum Distance Separable (MDS) code within the packet stream, leads to rate-optimal streaming codes capable of recovering from a arbitrary packet erasures, under a strict decoding delay constraint τ. Thus MDS codes are geared towards the efficient handling of the worst-case scenario corresponding to the occurrence of a erasures. In the present paper, we have an increased focus on the efficient handling of the most-frequent erasure patterns. We study streaming codes which in addition to recovering from a>1 arbitrary packet erasures under a decoding delay τ, have the ability to handle the more common occurrence of a single-packet erasure, while incurring smaller delay r<τ. We term these codes as (a,τ,r) locally recoverable streaming codes (LRSCs), since our single-erasure recovery requirement is similar to the requirement of locality in a coded distributed storage system. We characterize the maximum possible rate of an LRSC by presenting rate-optimal constructions for all possible parameters {a,τ,r}. Although the rate-optimal LRSC construction provided in this paper requires large field size, the construction is explicit. It is also shown that our (a,τ=a(r+1)-1,r) LRSC construction provides the additional guarantee of recovery from the erasure of h, 1 ≤ h ≤ a, packets, with delay h(r+1)-1. The construction thus offers graceful degradation in decoding delay with increasing number of erasures
Anil Kumar Lala (1950–2004)
No full textAnil Kumar Lala, Professor of Chemistry at the Indian Institute of Technology (IIT), Bombay died on 17 July 2004, following a stroke that he suffered three weeks earlier. Born on 13 January 1950, Lala did his B Sc from Delhi University and obtained his Ph D in 1974,working under the supervision of A. B. Kulkarni at Bombay University. His doctoral work was in the area of steroid chemistry, introducing him to the areas of NMR spectroscopy and mass spectrometry. Following a year at the Central Drug Research Institute in Lucknow, Lala moved to the State University of Ghent, Belgium,to work with Marc Anteunis. I first saw his name in a scientific publication,when the conformational analysis of methionine enkephalin, then recently discovered as the endogeneous ligand for the opioid receptor, was described by the French and Belgian groups, with Lala as a co-author (Roques, B. P. et al., Nature,1976, 262, 778). In 1976, he moved to Harvard University to work with Konrad Bloch and it is this period, which sparked his lifelong interest in membranes, specifically lipid–protein interactions. Lala joined the chemistry department at IIT,Mumbai in 1979 and it was here that he spent the remaining 25 years of his scientific career

Techniques for the performance analysis of queueing networks
No full textETDs are only available to UIUC Users without author permissionU of I OnlyAnalyzing the performance of queueing networks that do not admit a product form solution is a challenging problem. In this thesis we present some tools for doing so. Our attention is restricted to Markovian queueing networks.We first present a technique for bounding the performance of such networks. Assuming a steady state for functionals of the state, we obtain linear programs which bound the performance. This technique is illustrated using quadratic functionals to bound the performance of a class of Markovian queueing networks called reentrant lines. We also show how this technique may be applied to bound throughput and blocking probabilities in networks with buffer capacity constraints. In some cases bounds obtained using multimedial functional of the state are shown to approach the exact value when the degree of the multimedial increases.We also study another important technique for the analysis of queueing networks, namely, the fluid limit approach. This approach is used to establish the stability of a class of policies called Fluctuation Smoothing policies for open reentrant lines. We also show how the fluid limit approach can be used to obtain the asymptotic performance of closed queueing networks in heavy traffic. We then use fluid limits to establish the efficiency of Fluctuation Smoothing policies for closed reentrant lines, as well as the Harrison-Wein policy for two station closed reentrant lines.Made available in DSpace on 2011-05-07T14:22:46Z (GMT).

No. ZSI/ WGRC /IR/INV.14857.</p> <p> <b>Diagnosis</b>. The female of <i>Dasyproctus geethae</i> runs to <i>Dasyproctus pentheri</i> Leclercq, 1956 in the key to Asian and Oceanic <i>Dasyproctus</i> (Leclercq 2015) due to the overall appearance and texture of the body. It resembles the widespread <i>D. pentheri</i> in the punctation of head, mesosoma and metasoma; robustness of first metasomal tergum; conspicuous interocular carina dividing the frons, followed by a regular, concave and vaguely foveolate excavation and carina from one orbit to the other; maculation pattern on metasomal terga and well-imprinted supra-orbital fossa smaller than median ocellus. However, <i>D. geethae</i> <b>sp. nov.</b> differs from <i>D. pentheri</i> in having: clypeus with two well produced lobes apico-medially and pointed lateral process, no median indentations (in <i>D. pentheri</i>, clypeus quadridentate with a median indentation formed by an overhanging prolongation of median carina); with macula of Gt 2 elongated and similar to macula of Gt 3 and Gt 4 (in <i>D. pentheri</i>, macula of Gt 2 is rounded and smaller than maculae of Gt 3 –Gt 5); punctation on mesopleuron similar to that of the head, mesosoma and metasoma (in <i>D. pentheri</i>, punctation of mesopleuron is obsolete); POD almost equal to OOD (in <i>D. pentheri</i> POD is distinctly shorter than OOD); pronotum anterolaterally distinctly rugose with vertical wrinkles (in <i>D. pentheri</i>, pronotum has no large vertical wrinkles anterolaterally); Gt 1 with anterior third distinctly and conspicuously rugose (in <i>D. pentheri</i>, Gt 1 uniformly sculptured with widely separated pits and alutaceous interspaces); length of Gt 1 distinctly less than 2×, its greatest width, 1.4× Gt 2 (in <i>D. pentheri</i>, length of Gt 1 roughly 2× its greatest width, not greatly exceeding the length of Gt 2). In the key to males of <i>Dasyproctus</i> from Asia and Oceania (Leclercq 2015), the male of <i>D. geethae</i> <b>sp. nov.</b> runs to the couplet separating <i>D. pentheri</i> and <i>D. percarus</i> Leclercq. It resembles <i>D. pentheri</i> in having Gt 5 –Gt 6 with wide bands and punctation on head and mesosoma and a sturdy, short Gt 1. The male differs from <i>D. pentheri</i> in having pronotum with distinct rugae anterior to the collar (in <i>D. pentheri</i> pronotum without rugae or wrinkles anteriorly); Gt 2 finely punctured (in <i>D. pentheri</i> Gt 2 impunctate). The male of <i>D. geethae</i> <b>sp. nov.</b> resembles <i>D. percarus</i> in having Gt 2 punctate and pronotum with distinct rugae anterior to the collar. However, the new species differs in that: Gt 2 –Gt 6 maculated (in <i>D. percarus</i> all terga immaculate); Gt 1 short and sturdy (in <i>D. percarus</i> Gt 1 slenderer); punctation moderate on head and mesosoma (in <i>D. percarus</i> punctation on head and mesosoma is conspicuous and dense with reticulate interspaces).</p> <p> <b>Description</b>.
