Scheduling and Resource Management in Sustainable Construction Projects

Construction shapes our world but is taking a heavy toll on our planet. From our energy consumption to carbon emissions, how we build today affects the world in the future. As energy bills rise and our planet deteriorates, builders and developers are rethinking their approach. By embracing greener materials and sustainable construction, they are finding ways to have a lighter carbon footprint. Careful planning and effective resource management are the keys to making this work. These early decisions ripple through the entire project, ultimately determining whether we succeed in building for today and for future generations. This study explores the significance of strategic scheduling and resource optimization in environmentally friendly construction projects. Its objectives include examining how scheduling methods affect the incorporation and efficacy of green materials and energy-efficient technologies, assessing resource management approaches to minimize delays and budget overruns, and creating a framework that balances sustainability objectives with traditional construction limitations while maximizing long-term investment returns. The research data was gathered through case studies, structured interviews with industry experts, and an examination of life cycle assessments. The results underscore the necessity of incorporating sustainability considerations into project timelines and resource allocation strategies. This research offers practical insights for construction managers and policymakers, emphasizing how efficient scheduling and resource management can drive environmental and financial advantages in sustainable construction projects.

Three dimensional passive localization for single path arrival with unknown starting conditions

Introduced in this paper is the time difference of arrival (TDoA) conic approximation method (TCAM), a technique for passive localization in three dimensions with unknown starting conditions. The TDoA of a mutually detected signal across pairs of detectors is used to calculate the relative angle between the signal source and the center point of the separation between the detectors in the pair. The relative angle is calculated from the TDoA using a mathematical model called the TDoA approximation of the zenith angle (TAZA). The TAZA angle defines the opening angle of a conic region of probability that contains the signal source, produced by each detector pair. The intersecting region of probability is determined from the conic regions of probability and represents the volumetric region with the highest probability of containing the signal source. TCAM was developed and tested using synthetic data in a simulated environment

Scaling Up with Radically Embodied Cognition

Radically embodied cognitive science (REC) is typically concerned with basic cognition such as perception and action. However, complex cognition or higher-order cognition is difficult to explain for REC, as these theories eschew traditional representational explanations. This leaves REC with a scaling-up problem. In this dissertation I will explore options for REC to fix its scaling-up problem. I am specifically interested in autonoetic cognition, which is the ability to remember and imagine objects and events in the way they would be experienced if they were immediately present to be perceived. I contend that a simulationist account provides many of th necessary conceptual tools for understanding autonoetic cognition from a REC perspective. Furthermore, simulationist accounts are generally useful, as they are suggestive of a way to understand the observed neural activity and can be used to make empirical predictions. I will examine different simulationist theories in order to determine whether or not they can cohere with REC and help solve the scaling-up problem. Eventually I will argue that the REC commitment to reject representations makes the scaling-up problem insurmountable at this time

Relationships between Young Adults’ Housing Tenure, Elements of Perceived Job Security and Social Capital in Britain

Against the backdrop of the changing trends in tenure in the UK housing system, young adults are faced with different situations that continue to shape their housing consumption and decisions. This paper investigates the relationships between young adults’ housing tenure, social capital, and elements of perceived job security in Britain. Socio-psychological dimension of housing tenure decisions has been receiving attention by housing market analysts and practitioners seeking deeper understandings of UK housing market dynamics, particularly in the wake of changing tastes and preferences of young people concerning housing decisions across major cities of the world. More specifically, very little research has been done to investigate the contributions of social capital formation, for example, neighbourhood or social integration and social relations, and elements of perceived job security, on housing tenure transitions among British young adults. A quantitative approach has been applied to the British Household Panel Survey (BHPS) from 2001-2015. We discover that British young adults’ homeownership decisions are increasingly influenced by social capital and elements of perceived job insecurity, depending on their tenure of origin. Although we find minimal evidence of a combination effect from our variables of interest. Nevertheless, it is our view that findings from this study will significantly enhance our understanding of tenure shifts amongst young adults in the UK and provide property developers, local authorities, and central governments the knowledge and information to guide economic policies, urban renewal towards achieving better social cohesion and sustainable communities

Two conceptions of the mind

Since the cognitive revolution during the last century the mind has been conceived of as being computer-like. Like a computer, the brain was assumed to be a physical structure (hardware) upon which a computational mind (software) was built. The mind was seen as a collection of independent programs which each have their own specific tasks, or modules. These modules took sensory input data and transduced it into language-like representations which were used in mental computations. Recently, a new conception of the mind has developed, grounded cognition. According to this model, sensory stimulus is saved in the original format in which it was received and recalled using association mechanisms. Rather than representations being language-like they are instead multimodal. The manipulation of these multimodal representations requires processing distributed throughout the brain. A new holistic model for mental architecture has developed in which the concerted activity of the brain\u27s modal systems produces functional systems which are intimately codependent with one another. The purpose of this thesis is to explore both the modular and multimodal theories of mental architecture. Each will be described in detail along with their supporting paradigms, cognitivism and grounded cognition. After my expositions I will offer support for my own position regarding these two theories before suggesting avenues for future research

The Legal Framework for Sale of Goods in Nigeria: A Critical Analysis

There is a need to revisit the current legal framework for the sale of goods in Nigeria. This is inview of the fact that the law has numerous pitfalls as a result of its stagnant nature. The economicbackground that dictated its emergence has evolved over time. Thus, given the above backgroundit has become important to critically access the current legal framework to determine the extentof its relevance. This paper looked through the historical aspect of trading activities in Nigeriawhich led to the development of the extant laws. The paper also focused on the appraisal ofinternational instruments such as the CISG and also carried out a comparative analysis of thelaws of both the United Kingdom and that of Nigeria. Amongst all, the paper recommended thata complete overhaul of the Act is to be carried out in order to attend to recent developments andrealities in the commercial world

Maritime labour convention 2006: implications for seafarers after a decade

The protection of seafarers and the enforcement of their rights under national and international law has been an issue of great concern in recent years. This paper examined whether the current legal framework provides sufficient support for seafarers and to assess potential options for reform. In carrying out this study, the primary international legislation which is the Maritime Labour Convention (MLC) 2006 was considered and focus was on two jurisdictions, Panama and Philippine, which are of significant importance to the maritime world. The use of relevant journals and texts contributed to the discourse and opinions of key researchers in maritime law and practice was helpful in the analysis. This study found out that there are in existence some elements of protection available for the seafarers in the Maritime Labour Convention 2006. However, these provisions have suffered from poor implementation and inadequacy. It is acknowledged that steps have been taken to amend some of these provisions; however it is important that regular and consistent amendments should be effected as concerns are being raised by the seafarers as regards improvements in their rights and obligations.Keywords: Seafarers, Maritime Labour Convention, Ships, Abandonmen

Lattice Gas Automata for Reactive Systems

Reactive lattice gas automata provide a microscopic approachto the dynamics of spatially-distributed reacting systems. After introducing the subject within the wider framework of lattice gas automata (LGA) as a microscopic approach to the phenomenology of macroscopic systems, we describe the reactive LGA in terms of a simple physical picture to show how an automaton can be constructed to capture the essentials of a reactive molecular dynamics scheme. The statistical mechanical theory of the automaton is then developed for diffusive transport and for reactive processes, and a general algorithm is presented for reactive LGA. The method is illustrated by considering applications to bistable and excitable media, oscillatory behavior in reactive systems, chemical chaos and pattern formation triggered by Turing bifurcations. The reactive lattice gas scheme is contrasted with related cellular automaton methods and the paper concludes with a discussion of future perspectives.Comment: to appear in PHYSICS REPORTS, 81 revtex pages; uuencoded gziped postscript file; figures available from [email protected] or [email protected]
