To this end, we propose the notion of logical neighborhood as a way to logically partition a WSAN. Differently from physical neighborhoods, where a node’s physical transmissions range determines the set of devices it is able to communicate with, we here introduce an application-defined notion of neighborhood where the programmer specifies, using a declarative language we devised, the characteri...

The local positivity of solutions to logarithmically singular diffusion equations is investigated in some space-time domain E×(0, T ]. It is shown that if at some time level to ∈ (0, T ] and some point xo ∈ E the solution u(·, to) is not identically zero in a neighborhood of xo, in a measure-theoretical sense, then it is strictly positive in a neighborhood of (xo, to). The precise form of this ...

The factorial and construct equivalence of subscales assessing parents' and children's perceptions of the quality of their neighborhood was examined in Mexican American and European American families. All subscales (dangerous people in the neighborhood, sense of safety in the neighborhood, quality of the physical environment) demonstrated adequate partial factorial invariance across English- an...

we study the notion of harmonicity in the sense of symplectic geometry, and investigate the geometric properties of harmonic thom forms and distributional thom currents, dual to different types of submanifolds. we show that the harmonic thom form associated to a symplectic submanifold is nowhere vanishing. we also construct symplectic smoothing operators which preserve the harmonicity of distri...

The purpose of this note is to state a collection of results, all related to questions of uniqueness of smooth neighborhoods of finite complexes as imbedded (nicely) in differentiable manifolds. The reported results will appear in subsequent papers, the first of which is [l ]. The approach taken is always via the theory of simple homotopy types (due to J. H. C. Whitehead), and the main theorem ...

We consider the parallel machine scheduling problem where jobs have different earlinesstardiness penalties and a restrictive common due date. This problem is NP-hard in the strong sense. In this paper we define an exponential size neighborhood for this problem and prove that finding the local minimum in it is an NP-hard problem. The main contribution of this paper is to propose a pseudo-polynom...

The social dynamics of cities have long been dependent on their spaces and places. On the one hand, human interactions, and relationships are formed by the city form and on the other hand, the body recovers its identity from existing social life. The more a city can communicate with its citizens through physical features, the more it will affect their social identity. Thus, the city form can ha...
