The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Eugene McDermott
Eugene McDermott (February 12, 1899 in Brooklyn, New York - August 23, 1973 in Dallas, Texas) was an engineer and geophysicist who co-founded Geophysical Service Incorporated (GSI) in 1930 and later its parent company Texas Instruments in 1951. One of his most widely acclaimed patented inventions was for oil exploration equipment, related to the early use of reflection seismographs, still widely used today in oil exploration to map underground rock strata using sound wave technology. Other inventions ranged from geochemical applications to antisubmarine warfare, often focusing on the use of sonar. Early life and career Born in Brooklyn, New York, McDermott graduated from Stevens Institute of Technology in 1919 with a mechanical engineering degree. Upon graduation, he began working for the Goodyear Rubber Company. In 1923, McDermott found work with Western Electric Company where he first met J. Clarence Karcher. Earlier, Everette Lee DeGolyer, vice president and general man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIAM Journal On Control And Optimization
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million. The country is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the extremity of Myanmar. Thailand also shares maritime borders with Vietnam to the southeast, and Indonesia and India to the southwest. Bangkok is the nation's capital and largest city. Tai peoples migrated from southwestern China to mainland Southeast Asia from the 11th century. Indianised kingdoms such as the Mon, Khmer Empire and Malay states ruled the region, competing with Thai states such as the Kingdoms of Ngoenyang, Sukhothai, Lan Na and Ayutthaya, which also rivalled each other. European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Society For Industrial And Applied Mathematics
Society for Industrial and Applied Mathematics (SIAM) is a professional society dedicated to applied mathematics, computational science, and data science through research, publications, and community. SIAM is the world's largest scientific society devoted to applied mathematics, and roughly two-thirds of its membership resides within the United States. Founded in 1951, the organization began holding annual national meetings in 1954, and now hosts conferences, publishes books and scholarly journals, and engages in advocacy in issues of interest to its membership. Members include engineers, scientists, and mathematicians, both those employed in academia and those working in industry. The society supports educational institutions promoting applied mathematics. SIAM is one of the four member organizations of the Joint Policy Board for Mathematics. Membership Membership is open to both individuals and organizations. By the end of its first full year of operation, SIAM had 130 memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K-convexity In Rn
K-convexity in Rn is a mathematical concept. Formula Let ''\Kappa''= (''K0'',''K1'',...,''Kn'') to be a vector of (n+1) nonnegative constants and define a function \Kappa(.): \Re_+^n → \Re_+^1 as follows: \Kappa(x) = ''K0''\delta(''e''x) + \sum_^n''Ki''\delta(x_i), where ''e'' = (1,1,...,1) ∈ \Re^n, \Re_+^n = \, \delta(0) = 0 and \delta(z)= 1 for all z > 0. The concept of K-convexity generalizes ''K'' -convexity introduced by Scarf (1960) to higher dimensional spaces and is useful in multiproduct inventory problems with fixed setup costs. Scarf used ''K'' -convexity to prove the optimality of the (s, S) policy in the single product case. Several papers are devoted to obtaining optimal policies for multiple product problems with fixed ordering costs. This definition introduced by Gallego and Sethi (2005) is motivated by the joint replenishment problem when we incur a setup cost ''K0'', whenever we order an item or items and an individual setup cost ''Ki'' for each item i ...

Sethi-Skiba Point
Sethi-Skiba points, also known as DNSS points, arise in optimal control problems that exhibit multiple optimal solutions. A Sethi-Skiba point is an indifference point in an optimal control problem such that starting from such a point, the problem has more than one different optimal solutions. A good discussion of such points can be found in Grass et al. Definition Of particular interest here are discounted infinite horizon optimal control problems that are autonomous. These problems can be formulated as : \max_\int_0^ e^ \varphi\left(x(t), u(t)\right)dt s.t. : \dot(t) = f\left(x(t), u(t)\right), x(0) = x_, where \rho > 0 is the discount rate, x(t) and u(t) are the state and control variables, respectively, at time t, functions \varphi and f are assumed to be continuously differentiable with respect to their arguments and they do not depend explicitly on time t, and \Omega is the set of feasible controls and it also is explicitly independent of time t. Furthermore, it is assu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sethi Model
The Sethi model was developed by Suresh P. Sethi and describes the process of how sales evolve over time in response to advertising. The model assumes that the rate of change in sales depend on three effects: response to advertising that acts positively on the unsold portion of the market, the loss due to forgetting or possibly due to competitive factors that act negatively on the sold portion of the market, and a random effect that can go either way. Suresh Sethi published his paper "Deterministic and Stochastic Optimization of a Dynamic Advertising Model" in 1983. The Sethi model is a modification as well as a stochastic extension of the Vidale-Wolfe advertising model. The model and its competitive and multi-echelon channel extensions have been used extensively in the literature.Bensoussan, A., Chen, S., Chutani, A., Sethi, S.P., Siu, C.C., and Yam, S.C.P., "Feedback Stackelberg-Nash Equilibria in Mixed Leadership Games with an Application to Cooperative Advertising," ''SIAM Jour ...
