Many current Evolutionary Algorithms (EAs) suffer from a tendency to converge prematurely or stagnate without progress for complex problems. This may be due to the loss of or failure to discover certain valuable genetic material or the loss of the capability to discover new genetic material before convergence has limited the algorithm's ability to search widely. In this paper, the Hierarchical ...

The explosive growth in mobile broadband traffic, driven by smart phones and tablets that significantly increase traffic per subscriber, has accentuated the spectrum shortage for Commercial Mobile Radio Services (CMRS). The spectrum shortage is driving up the costs of deploying competitive 4G mobile broadband networks and is fueling pressure for industry consolidation, and thus poses a threat t...

The challenges of how to respond to climate change and ensure sustainable development are currently high on the political agenda among the world’s leading nations. The Clean Development Mechanism (CDM) is part of the global carbon market developing rapidly as part of the Kyoto response towards mitigation of global warming. One of the aims of the CDM is to achieve sustainable development in deve...

Global mental health (GMH) is a growing domain with an increasing capacity to positively impact the world community's efforts for sustainable development and wellbeing. Sharing and synthesizing GMH and multi-sectoral knowledge, the focus of this paper, is an important way to support these global efforts. This paper consolidates some of the most recent and relevant 'context resources' [global mu...

Background Sustainable public transport is not an option; it is a necessity [1]. In a media competition run by the Institution of Engineering and Technology (IET), we introduced an award-winning design model of financially secure and sustainable automatic fare collection (AFC) [2]. In the public transport industry, AFC commonly refers to transit providers’ automated ticketing systems for collec...

In this paper, maximum sustainable yield policy in prey-predator system is discussed where the prey population follows logistic law of growth. Here a model is proposed involving linear prey–predator interaction and intra-specific competition among predator populations. The growth rate of the predator depends upon predation on the modelled and alternate prey. In traditional prey–predator system,...

Modern bioenergy is seen as a promising option to curb greenhouse gas emissions. There is, however, a potential competition for land and water between bioenergy and food crops. Another question is whether biomass for energy use can be produced in a sustainable manner given the current conventional agricultural production practices. Other than the land and water competition, this question is oft...

Balanced harvesting, where species or individuals are exploited in accordance with their productivity, has been proposed as a way to minimize the effects of fishing on marine fish communities and ecosystems. This calls for a thorough examination of the consequences balanced harvesting has on fish community structure and yield. We use a size- and trait-based model that resolves individual intera...

Future international social stability cannot be built on “imposed balance.” Addressing the problem of the commons is a key to stability. This requires individuals and groups to study the future. Unyielding ethnic, philosophical, or religious group assertiveness is destabilizing. Inter-group competition in a finite space will create imbalance between short-term and long-term stability and obviat...

With the rapid development of China's economy, construction scale is more and more big; the construction enterprises are facing new opportunities for development, while also facing the fierce competition in the industry. Financial management of construction enterprises is an important measure to ensure the sustainable operation of enterprises, play an important role in the enterprise management...
