Small Scale Models for Steel Frameworks

Engineering Journal, 1966
The analysis and design of steel structures has become increasingly sophisticated and efficient in the last decade. For conventional structures, present methods of analysis can be employed with confidence with the proportioning of members based upon some prescribed criteria, such as building and bridge construction codes.

Modelling entrepreneurship in small-scale enterprises

Applied Economics Letters, 2005
In the small-scale enterprises, the entrepreneurs and managers are often one and the same. This paper attempts to estimate the entrepreneurial competence in small-scale enterprises decomposing into entrepreneurial ability and managerial efficiency using the frontier production function.

Modeling of small scale reverse osmosis systems

Desalination, 1985
Abstract A simulation model was developed and verified for a small scale reverse osmosis (RO) system operating in a closed-loop concentrating mode. The model combines material balances on the feed tank, membrane module and product tank with membrane mass-transfer models.

Small‐scale models of oceanic transform zones

Journal of Geophysical Research: Solid Earth, 1996
Previous studies about oceanic transform zones reveal major morphological and structural differences that cannot be explained by simple factors such as spreading rates or offsets. In order to determine how kinematic and mechanic parameters control the deformation pattern, we perform small‐scale modeling using sand and silicone putty as analog material ...

Wavelet based model for small-scale turbulence

Physics of Fluids, 1995
Using a vector wavelet decomposition of the velocity field a simple model for locally isotropic turbulence has been derived from the Navier–Stokes equation (NSE). This model, which involves no empirical or ad hoc parameter, incorporates nonlocal interscale interactions, reveals backscatter and can be applied to represent small-scale turbulence in LES ...

MRIO modelling of small-scale trigeneration systems

2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019
This paper proposes a multi-regional input- output modelling method for small-scale trigeneration systems. Compared with other methods, a total quantity array which is used in this paper rather than an input array, has two advantages. Firstly, it is an elegant format with modular assembling convenience.

Global Linear Modeling of Small Scale Helicopter

2009
The establishment of global helicopter linear model is indispensable for the design of an onboard autonomous control system by using linear control laws. To date, however, it has never been afforded in the literatures. In the first principle approach, the mathematical model is developed using basic helicopter theory accounting for particular ...

Stochastic models for small-scale turbulence

2003
It was explained in section 4.5 that the calculation of turbulent reacting flows by means of DNS is found to be unfeasible for many relevant flows. The simplest way to overcome this problem is the use of RANS equations for ensemble-averaged variables.

Towards Modelling Interventions in Small-Scale Fisheries

2020
Interventions often have unintended effects, particularly when they target outcomes in complex social-ecological systems (SES), such as fisheries. Development agencies strive for ‘doing development differently’, because past efforts have often been unsuccessful. The question then is how to do better. Science can make a major contribution here.
