Among all the water bodies in Jammu & Kashmir Dal Lake has a peculiar significance due to its location in the heart of the capital city Srinagar. Historical studies over last fifteen hundred years indicate a continuous squeezing of the Lake due to different natural and manmade interventions. Over this long period, the governance of the land has passed through various wise and ugly human plans besides some slow natural processes. The mathematical modelling of such a dynamics is not an easy task because of the many intervening variables and the difficulty which implies their measurements. On the other hand, during the last decades, the use of Cellular Automata (CA) techniques to simulate the behaviour of linear or non-linear systems is becoming of great interest. This fact is mainly due to the fact that this approach depends largely on local relations and a series of rules instead of precise mathematical formulae. The infrared (IR) satellite imagery can be helpful in identifying the different areas of interest using CA as a tool of image processing. The study will not only separate the areas of interest but also pave a way towards a comprehensive study of all the identified zones using spectral signatures received from the continuous IR imagery of both pre-monsoon and post-monsoon periods in future.

AbstractMargaret Ann Harvey was born on 18 May 1792 in St Peter Port, which is the capital city of Guernsey, the second-largest of the Channel Islands; and died there on 4 April 1903 at the reported age of 110. In this contribution, her exceptional age is thoroughly validated. Considering the data collected on her parents and siblings, there is no possibility of an erroneous linkage, as the name of Margaret and Ann appears only once in the birth records, her family’s birth intervals were narrow, and the dates of death of her siblings have been checked. As she did not have children, her name was not found in civil registration records after her marriage in 1823 until her death in 1903. This lack of records might have made it difficult to prove that the person who died at age 110 in 1903 was the same person who married in 1823 at age 30. Fortunately, she was enumerated in six successive censuses from 1851 to 1901, and a comparison of the ages reported in these censuses and her exact ages shows only minor deviations. Moreover, numerous letters and her numerous diaries help us to follow her life during that long period. Upon reaching age 100, she became famous in Guernsey. Thus, there are many photos of her and press articles about her life. These data support the reliability of the reported chronology of her life events, and thus allow us to validate this exceptional case. Accordingly, we can state that Margaret Ann Harvey Neve is the first documented female supercentenarian. As in the case of recently deceased supercentenarian Emma Morano, her life spanned three successive centuries – albeit one century earlier.

Indonesia has a capital city which is one of the many big cities in the world called Jakarta. Jakarta's role in the dynamics that occur in Indonesia is very central because it functions as a political and government center, and is a business and economic center that drives the economy. Recently the discourse of the government to relocate the capital city has invited various reactions from the community. Therefore, in this study, sentiment analysis of the relocation of the capital city was carried out. The analysis was performed by doing a classification to describe the public sentiment sourced from twitter data, the data is classified into 2 classes, namely positive and negative sentiments. The algorithms used in this study include Naïve Bayes classifier, logistic regression, support vector machine, and K-nearest neighbor. The results of the performance evaluation algorithm showed that support vector machine outperformed as compared to 3 algorithms with the results of Accuracy, Precision, Recall, and F-measure are 97.72%, 96.01%, 99.18%, and 97.57%, respectively. Sentiment analysis of the discourse of relocation of the capital city is expected to provide an overview to the government of public opinion from the point of view of data coming from social media.

The Mongol conquest of the IRANIAN EAST put an end to the classical Islamic coinage introduced by ʿAbd al-Malik. At first, considerable local diversity existed under the early Mongols and Ilkhanids, but Ghazan and Rashid al-Din imposed a uniform monetary system on the many Ilkhanid mints, setting the pattern for eastern coinage for several hundred years. For this long period, it is easiest to treat separately Western Iran, Eastern Iran, the Steppes, and Anatolia, despite the many interrelationships of their coinages.

Cellular automata (CA) and lattice-Boltzmann (LB) models are two possible approaches to simulate fluid-like systems. CA models keep track of the many-body correlations and provide a description of the fluctuations. However, they lead to a noisy dynamics and impose strong restrictions on the possible viscosity values. On the other hand, LB models are numerically more efficient and offer much more flexibility to adjust the fluid parameters, but they neglect fluctuations. Here we discuss a multiparticle lattice model which reconciles both approaches. Our method is tested on Poiseuille flows and on the problem of ballistic annihilation in two dimensions for which the fluctuations are known to play an important role.

When Bangkok was named the capital of Siam it held an inconsiderable population of some fifty thousand. Now, two hundred years later, this capital city boasts some five million residents. A prodigious population increase, indeed: a hundredfold gain generated by an ever-increasing rate of growth, which, after gathering momentum only gradually during the greater part of the nineteenth century, rose rapidly around the turn of this century and has since soared. The foregoing compendious description is shown on Figure I as the curve which charts the march of the population of the built-up area of the city. I have calculated this particular population by reworking the numbers reported at particular times by certain “eyewitnesses”. Since the turn of this century, the “eyewitnesses” have been censuses and registration counts for administrative areas; earlier “witnesses” are the postal census of 1882 and the considered estimate of the population of the city proper in 1822 by the “very trustworthy” Dr John Crawfurd, Head-of-Mission to the Courts of Siam and Cochin China deputised by the Governor-General of India. I have forsaken all the many other pre-twentieth century eyewitness estimates of the population of Bangkok. Why?

Nicolas Desmarest's Géographie-Physique, his contribution to the Encyclopédie Méthodique, is a surprisingly useful resource for his biographer. The four volumes he completed during his declining years offer insights into his activities over a long period, such as the extent of his travels, and the sorts of phenomena he selected for observation. Leaving aside those articles that he plagiarized, the many entries he wrote testify to the depth of his commitment to a place-specific construction of a new science of the Earth. In comparison with the article ‘Géographie Physique’ that he provided for the Diderot-d'Alembert Encyclopédie (1757), the components of Géographie-Physique also exhibit Desmarest's deepened interest in cultivating knowledge of the Earth's past. Nonetheless his basic conception of physical geography—which he regularly distinguished from both Theories of the Earth and the emerging géologie (whose definition he found elusive)—remained centered on a search for law-like generalizations about the natural world's order, rather than its historical development.

Avant-Folk is the first comprehensive study of a loose collective of important British and American poets, publishers, and artists (including Lorine Niedecker, Ian Hamilton Finlay, and Jonathan Williams) and the intersection of folk and modernist, concrete and lyric poetics within the small press poetry networks that developed around these figures from the 1950s up to the present day. This book argues that the merging of the demotic with the avant-garde is but one of the many consequences of a particularly vibrant period of creative exchange when this network of poets, publishers, and artists expanded considerably the possibilities of small press publishing. Avant-Folk explores how, from this still largely unexplored body of work, emerge new critical relations to place, space, and locale. Paying close attention to the transmission of demotic cultural expressions, this study of small press poetry networks also revises current assessments regarding the relationship between the cosmopolitan and the regional and between avant-garde and vernacular, folk aesthetics. Readers of Avant-Folk will gain an understanding of how small press publishing practices have revised these familiar terms and how they reconceive the broader field of twentieth-century British and American poetry.
