Physical Review E, 2006
We have studied the collective calcium signaling behavior of an array of coupled N cells, taking into account the internal noises resulting from the small cell size V. The system's performance was characterized by the reciprocal coefficient of variance (RCV) of the calcium spike train.

On the optimal size of a robust swarm
International Journal of Computer Applications in Technology, 2011A systematic approach to optimising swarm size is proposed to ensure the robustness when individual swarm units possibly fail while the interference among the units is maintained at an acceptable level. Considering failures of swarm units (e.g. motor and control system) or a swarm system deployed for a hazardous mission, each swarm unit has a certain ...

Optimizing the Size and Configuration of Combinatorial Libraries
Journal of Chemical Information and Computer Sciences, 2002This paper addresses a major issue in library design, namely how to efficiently optimize the library size (number of products) and configuration (number of reagents at each position) simultaneously with other properties such as diversity, cost, and drug-like physicochemical property profiles.

Analysis of optimal thread pool size
ACM SIGOPS Operating Systems Review, 2000The success of e-commerce, messaging middleware, and other Internet-based applications depends in part on the ability of network servers to respond in a timely and reliable manner to simultaneous service requests. Multithreaded systems, due to their efficient use of system resources and the popularity of shared-memory multi-processor architectures ...

Optimal body size in bumblebees
Oecologia, 1978It is hypothesized that the body size of a bumblebee will be that size which maximizes its average net rate of energy intake while collecting nectar. A mathematical model is developed with the result that the net rate of energy intake of a nectar-collecting bumblebee is expressed as a function of the body size of the bumblebee. From this model the body

On the Optimal Fiscal Treatment of Family Size [PDF]
FinanzArchiv, 2002 Should a benevolent social planner subsidize family size? Typically, contributions assuming exogenous fertility yield an affirmative answer, while those assuming endogenous fertility do not reach definite conclusions. We re-examine the endogenous fertility model, and find that when redistribution is accomplished mostly using non-income taxes, there is ...

Maritime Policy & Management, 1990
The cost per container movement incurred by a containership per voyage leg on a given route is minimized under various scenarios. The principal conclusions reached from a comparative analysis of the optimal containership sizes are: (1) for a route of a given distance and the same time in port per port call, optimal containership size declines as the ...

On the optimal size of system model
1973The problem of finding the best size for the system model is considered. By explicitly synthesizing the complexity cost of a proposed model, one is able to transform this problem into a constrained integer programming problem.
