Under the assumption that competition (Darwinian in nature) reigns in the stock market, we analyzethe behavior of company stocks as if they were species competing for investors’ resources. The approachrequires the study of dollar values and share volumes, daily exchanged in the stock market, via logistic growthfunctions. These two variables, in contrast to prices, obey the law of natural growth in competition, which likeevery natural law, is endowed with predictability. A number of unexpected insights about the stock marketemerge. The forecasts indicate that whereas there is no looming crash in the near future, no significant growthshould be expected either. The DJIA is to hover around 9500 depicting large erratic excursions above andbelow this level for a few years. The use of Volterra-Lotka equations demonstrates that the 1987 crash alteredthe stock-bond interaction from a symbiotic to a predator-prey relationship with stocks acting as predators. This research work has lead to the publication of the book "An S-Shaped Trail to Wall Street" by T. Modis,(Growth Dynamics, Geneva, 1999).

Henry B. Wonham, “Realism and the Stock Market: The Rise of Silas Lapham” (pp. 473–495) William Dean Howells’s The Rise of Silas Lapham (1885) is usually approached as a representative text in the American realist mode and an unambiguous expression of Howells’s disdain for—in Walter Benn Michaels’s words—“the excesses of capitalism,” especially as embodied in the novel’s rendering of “the greedy and heartless stock market.” Like many commentators of the period, Howells promoted a traditional view of honest industry against the emerging phenomenon of speculative finance, and yet to read the novel as an allegory of opposition to Wall Street speculation is to oversimplify Howells’s complicated attitudes toward high finance and to make a caricature out of the novel’s treatment of complex economic developments. In this essay, I reassess Silas’s investment career and the novel’s surprisingly dense engagement with the dynamics of securities trading as a form of commerce. Critics such as Michaels and Neil Browne have contended that through Silas’s failed investment career, Howells “attempts to disarticulate…an emergent market ethos,” but as I read the novel this same “market ethos” is inseparable from Howells’s conception of realism and of the vocation of the literary realist.

Weak Form Efficiency

The purpose of this paper is to examine the random walk hypothesis (RWH) by testing the weak-form efficiency in the Nepalese capital market. Descriptive, correlation and causal comparative research design has been used for analyzing the variables and different phenomenon. This research has been prepared only with the help of secondary data. Closing price of company has been collected and analyzed for the period 2015/16-2019/20. Thus researcher tried to analyze the market efficiency with the help of five years data (daily closing price).There are altogether around 233 companies listed in NEPSE. So to make this research feasible and simple researcher has selected only 10 companies from the NEPSE by using purposive sampling technique. In course of selecting company researcher has tried to incorporate only financial sectors as commercial banks, finance companies, insurance, and microfinance companies but development bank has not been taken as sample due to same nature of commercial bank. Researcher examined the weak form efficiency of the Nepal stock exchange (NEPSE) using auto correlation test (parametric test) and run test (non-parametric test) for the period of 2015/16-2019/20. Mainly this research work tested the efficient market hypothesis of Nepalese stock market with the help of daily closing price of 10 Sample Company of different sectors. The market is inefficient in the weak form implies that the NEPSE does not follow a random walk. This means that the NEPSE provides an opportunity for out- performance by skillful managers and investment specialists. Auto correlation exists in price of stock evident that there is high level of dependency of price of stock with the previous ones. It will be easy for speculator and trader to exploit the market and gain handsome profit from the market. All investor are not assumed to be rational in inefficient market, most of the people say investor are investing on the basis of market rumor. Market may be inefficient due the asymmetric of information and insider trading.

From Main Street to Wall Street examines the relation between the economy and the stock market. It discusses the academic theories and empirical facts, and guides readers through the fascinating interaction between economic activity and financial markets. Itexamines what causes long-run economic growth and shorter-term business-cycle fluctuations and analyses their impact on stock markets. From Main Street to Wall Street also discusses how investors can use knowledge of economic activity and financial markets to formulate expectations to future stock returns. The book relies on data, and figures and tables illustrate arguments and theories in intuitive ways.In the end, From Main Street to Wall Street helps academic scholars and practitioners navigate financial markets by understanding the economy.

Traditionally, routing decisions have been based on minimizing travel time as the associated cost. Eco-routing considers the environmental aspects (e.g., emissions and fuel) as part of the travel cost to mitigate the undesirable impact of transportation systems on the environment. Unlike the existing eco-routing review papers, this research work is aimed at providing a three-factor taxonomy at a more disaggregated level from the optimization perspective and map eco-routing studies to the proposed taxonomy. Furthermore, the strengths and weaknesses of the presented models are summarized. Our main findings include (a) a majority of studies optimized one objective at a time; (b) the microscopic level of aggregation of the flow and emission/fuel models was rarely employed for large case studies, due to the associated complexity; and (c) all of the reviewed studies were applied in a centralized routing system environment. In the near future, when intelligent vehicles will be on the roads, a multi-objective distributed routing framework can be employed with a microscopic level of aggregation for both traffic and emission models, which is capable of operating on largescale networks in real time. Additionally, short-term spatiotemporal prediction of GHG cost is a crucial aspect to be tackled.

New Energy Vehicles

New energy vehicles have bright prospect in the near future. In new energy vehicles some parts which are driven by engine through transmission will be replaced by electric drive, such as refrigeration compressor used for air conditioning and air compressor used for air brake system. Because of advantages, such as high efficiency, low friction, compact structure, and so on, linear compressor is suitable to solve above problems. In this paper a novel electric linear compressor is presented. Research work, such as simulation, structure design, control design, has been done. Further experiments are being done by my research team. We believe that electric linear compressor is worthy of being researched to popularize new energy vehicles.

Ocean acidification poses a range of threats to marine invertebrates; however, the emerging and likely widespread effects of rising carbon dioxide (CO 2 ) levels on marine invertebrate behaviour are still little understood. Here, we show that ocean acidification alters and impairs key ecological behaviours of the predatory cone snail Conus marmoreus . Projected near-future seawater CO 2 levels (975 µatm) increased activity in this coral reef molluscivore more than threefold (from less than 4 to more than 12 mm min −1 ) and decreased the time spent buried to less than one-third when compared with the present-day control conditions (390 µatm). Despite increasing activity, elevated CO 2 reduced predation rate during predator–prey interactions with control-treated humpbacked conch, Gibberulus gibberulus gibbosus ; 60% of control predators successfully captured and consumed their prey, compared with only 10% of elevated CO 2 predators. The alteration of key ecological behaviours of predatory invertebrates by near-future ocean acidification could have potentially far-reaching implications for predator–prey interactions and trophic dynamics in marine ecosystems. Combined evidence that the behaviours of both species in this predator–prey relationship are altered by elevated CO 2 suggests food web interactions and ecosystem structure will become increasingly difficult to predict as ocean acidification advances over coming decades.
