Survey methodologists have acknowledged that the social environment may influence survey and census participation—both at societal level community level. The 2020 COVID-19 pandemic affected daily life throughout entire U.S., but to differing degrees depending upon particular neighborhood or community. In this article, we use U.S. Centers for Disease Control county-level infection data coupled w...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...

development, a concept that is called often to process of moving from point to another that covers various aspects such as economic growth, structural change, industrialization, self-actualization and cultural, religious, national and individual self-reliance. a sustainable development is a new concept of economic growth. a growth that is as justice and opportunity for all people that living in...

We analyze the dynamics of a two-dimensional cellular automaton, 2D Minority, for the Moore neighborhood (eight neighbors per cell) under fully asynchronous dynamics (where only one random cell updates at each time step). Even if 2D Minority seems a simple rule, from the experience of Ising models and Hopfield nets, it is known that models with negative feedback are hard to study. This automato...

We contribute to the evaluation of urban renewal policies based on a large-scale program launched in France 2004. Using an estimator aimed at avoiding bias estimation treatment effects that are heterogeneous across groups or time periods, and complementing its results with more precise double fixed difference-in-differences estimator, we find no significant aggregate impact housing prices. iden...

In this paper, an effective approach based on the variable neighborhood search (VNS) algorithm is presented to solve the uncapacitated multilevel lot-sizing (MLLS) problems with component commonality and multiple end-items. A neighborhood structure for the MLLS problem is defined, and two kinds of solution move policies, i.e., move at first improvement (MAFI) and move at best improvement (MABI)...
