Xqx Based Modeling For General Integer Programming Problems

We present a new way to model general integer programming (IP) problems with in- equality and equality constraints using XQX. We begin with the definition of IP problems folloby their practical applications, and then present the existing XQX based models to handle such problems. We then present our XQX model for general IP problems (including binary IP) with equality and inequality constraints, and also show how this model can be applied to problems with just inequality constraints. We then present the local optima based solution procedure for our XQX model. We also present new theorems and their proofs for our XQX model. Next, we present a detailed literature survey on the 0-1 multidimensional knapsack problem (MDKP) and apply our XQX model using our simple heuristic procedure to solve benchmark problems. The 0-1 MDKP is a binary IP problem with inequality con- straints and variables with binary values. We apply our XQX model using a heuristics we developed on 0-1 MDKP problems of various sizes and found that our model can handle any problem sizes and can provide reasonable quality results in reasonable time. Finally, we apply our XQX model developed for general integer programming problems on the general multi-dimensional knapsack problems. The general MDKP is a general IP problem with inequality constraints where the variables are positive integers. We apply our XQX model on GMDKP problems of various sizes and find that it can provide reasonable quality results in reasonable time. We also find that it can handle problems of any size and provide fea- sible and good quality solutions irrespective of the starting solutions. We conclude with a discussion of some issues related with our XQX model

Cho. Dharman's Sool novel from the point of view of social anthropology

As a result of the development of the human mind, there are many forms of literature that have emerged. These reflect the change in the development of language from time to time. The novel is one of these forms of reflection. All the anthropological aspects of people's lives are expressed in the novels. In order to learn about the people, there are more sociological elements of novel literature that record the folk life than the classical literature. On that basis, after Ki.Ra. & Poomani, the life philosophies of the people of karisal region, and the novel 'Sool', which records a great deal in terms of the devendrakula Vellalar race known as Pallar, examines and explains the sociocultural and anthropological aspects recorded in them

Decolorization and Biodegradation of basic violet dye by fungal- bacterial consortia

The present study was aimed to test the ability of Penicillium citrinum MTCC 8009, Aspergillusterreus MTCC 3006, Bacillus cohnii and their consortia to decolorize basic violet dye. Different parameters such as initial dye concentration, dye to inoculum ratio and period of incubation were studied for the decolourization of the dye. The developed fungal-bacterial consortia exhibited maximum percent decolorization (92%) ability when compared to the treatment of dyes by individual microbes. Percent decolorization of basic violet dye (92%) was more efficient using fungal-bacterial (Penicillium citrinum and Bacillus cohnii) consortia than with individual cultures. Phyto-toxicity results indicated that bacterial-fungal consortia (Penicillium citrinum and Bacillus cohnii) treatment  was believed to degrade the dyes to non-toxic intermediates. The FTIR analysis also revealed that decolorization of basic violet dyes was due to its degradation

Seaweeds-products, processing and utilization

Seaweeds-products, processing and utilization Marine macroalgae which are popularly termed as Seaweeds belong to the primitive group of nonflowering plants known as Thallophyta. They are autotrophic plants and grow in the intertidal and subtidal regions of the sea

Stochasticity among Victims of COVID-19 Pandemic

This article provides a thorough explanation of methods and theoretical concepts to detect infectivity of COVID-19. The concept of heterogeneity is discussed and its impacts on COVID-19 pandemics are explored. Observable heterogeneity is distinguished from non- observable heterogeneity. The data support the concepts of heterogeneity and the methods to extract and interpret the data evidence for the conclusions in this paper. Heterogeneity among the vulnerable to COVID-19 is a significant factor in the contagion of COVID-19, as demonstrated with incidence rates using data of a Diamond Princess cruise ship. Given the nature of the pandemic, its heterogeneity with different social norms, pre- and post-voyage quick testing procedures ought to become the new standard for cruise ship passengers and crew. With quick testing, identification of those infected and thus, not allowing to embark on a cruise or quarantine those disembarking, and other mitigation strategies, the popular cruise adventure could become norm for safe voyage. The novel method used in this article adds valuable insight in the modeling of disease and specifically, the COVID-19 virus

Marine fish calendar. V. Kakinada

The current article provides the marine fish landing data of various gears at Kakinada landing centre, Andhrapradesh. Data of the period I98l-'85 from the trawlers and 1980-'82 from indigenous gear and published information on different species from Kakinada are used for the present fish calendar

Reachability for dynamic parametric processes

In a dynamic parametric process every subprocess may spawn arbitrarily many, identical child processes, that may communicate either over global variables, or over local variables that are shared with their parent. We show that reachability for dynamic parametric processes is decidable under mild assumptions. These assumptions are e.g. met if individual processes are realized by pushdown systems, or even higher-order pushdown systems. We also provide algorithms for subclasses of pushdown dynamic parametric processes, with complexity ranging between NP and DEXPTIME.Comment: 31 page
