Composite models of quarks and leptons
We review the various constraints on composite models of quarks and leptons. Some dynamical mechanisms for chiral symmetry breaking in chiral preon models are discussed. We have constructed several "realistic candidate" chiral preon models satisfying complementarity between the Higgs and confining …

Holographic and Composite Models of the Axion
… excellent dark matter candidate. If the axion is composite, it must be bound by a novel strong interaction. Some strongly-coupled models, mathematically intractable until now, are recently discovered to be calculable through a mapping onto 5-dimensional gravity. We propose a series of composite …

'Composite' models of project management : integration of control-oriented and adaptive approaches in rural water supply
This thesis explores the case of an International Development Association (IDA) assisted rural water supply and sanitation project in Azad Jammu & Kashmir, Pakistan, to raise some important questions about how donor-assisted projects are administered in developing countries. The paper analyzes some …

Analytical and Experimental Investigation of Interphase and Dispersion Effects on the Mechanical Stiffness of Cellulose Nanocomposites
… on the elastic behavior of cellulose nanocomposites was investigated using a number of composite models, experimental data and a thorough literature review. Cellulose nanocomposites consisting of soy protein isolate (SPI) and cellulose nanocrystals (CNC) or polydopamine coated cellulose …

The use of neural networks in the combining of time series forecasts with differential penalty costs
… By combining individual techniques to form composite forecasts in order to improve on the forecasting accuracy, researchers have taken advantage of the various strengths of these techniques. A number of combining methods have proven to yield better forecasts than individual methods, with the …

Atomistic simulation of deformation induced rotation in Cu-Nb composites
… (ARB) of three copper-niobium (Cu-Nb) nano-composite models is simulated using molecular statics techniques to assess the rotational stability of Cu-Nb interfaces at high strains up to 90% thickness reduction. Crystals strain and rotate under compression, and certain Cu-Nb composites have …

Influence of geometry on creep and moisture movement of clay, calcium silicate and concrete masonry
… and brick or block units in order to verify composite model expressions for predicting masonry movements. Simulation of moisture diffusion of the corresponding mortarjoints and embedded bricks or block were made in terms of V/S ratio by partial sealing of the individual mortar prisms and …

A reevaluation of distortional isomerism.
… presenting a consistent description of their composite nature. A single crystal X-ray structure determination of a crystal of green "MoOCl₂(PMe₂Ph)₃" allowed the compositional disorder to be partially resolved in this case, due to the high composition of MoOCl₃(PMe₂Ph)₃ in the sample (ca. 0.30 …

Online cause-related marketing: the impact of donation amount and congruence on consumers’ response.
… and practical contributions by identifying composite models of consumers’ response towards ACM and CS tactics, with more favourable purchase intention towards ACM than CS.

Ultrasonic hot spots in solids
… remain elusive. Typical solid explosives are composites of EM crystals with polymer binders. Multiple mechanisms have been proposed for hot spot formation in these structures, such as shear band formation in explosive crystals, void collapses, interfacial friction and triboelectric discharge. …

Smart passive adaptive control of laminated composite plates (through optimisation of fibre orientation)
In the classical laminate plate theory for composite materials, it is assumed that the laminate is thin compared to its lateral dimensions and straight lines normal to the middle surface remain straight and normal to the surface after deformation. As a result, the induced twist which is due to the …

The adaptation and demolition of existing buildings on masterplan sites
… structural, event-sequence and agency models, are applied to the research findings to offer a potential theoretical framing applicable to the masterplan scale. Through the multiple lenses provided by composite models, the variations in the factors governing decisions are explained. …

Understanding ethnic entrepreneurship in agricultural settings : qualitative comparative analysis of ethnic groups in New Zealand agriculture
… development of ethnic networks in business. This composite model of ethnic entrepreneurship considered host hostility in conjunction with collectivistic cultural endowments as the principal causal configuration responsible for development of ethnic business networks. The model also pointed at the …

Relevant Operators of Particle Physics and Cosmology
<p>Although the Standard Model of Particle Physics can reproduce the results of all the experiments performed to this date, it can only be an effective theory of fundamental physics. However, treating the Standard Model this way brings its own set of challenges; namely, the coefficients of relevant …
