The use of containers have greatly reduced handling operations at ports and at all other transfer points, thus increasing the efficiency and speed of transportation. This was done in an attempt to cut down the cost of maritime transport, mainly by reducing cargo handling and costs, and ships' time in port by speeding up handling operations. This paper discusses the major factors influencing the transfer efficiency of seaport container terminals. A network model is designed to analyse container progress in the system and applied to a seaport container terminal. The model presented here can be seen as a decision support system in the context of investment appraisal of multimodal container terminals. (C) 2000 Elsevier Science Ltd.

Optimising the container transfer schedule at the multimodal terminals is known to be NP-hard, which implies that the best solution becomes computationally infeasible as problem sizes increase. Genetic Algorithm (GA) techniques are used to reduce container handling/transfer times and ships' time at the port by speeding up handling operations. The GA is chosen due to the relatively good results that have been reported even with the simplest GA implementations to obtain near-optimal solutions in reasonable time. Also discussed, is the application of the model to assess the consequences of increased scheduled throughput time as well as different strategies such as the alternative plant layouts, storage policies and number of yard machines. A real data set used for the solution and subsequent sensitivity analysis is applied to the alternative plant layouts, storage policies and number of yard machines.

This 45 minute non-verbal intermedial performance for children was adapted from the picture book I authored of the same name. The process involved writing and re-writing text and music with the result being a new draft of both script and soundtrack. Part of the judging process for the award the script was nominated for involved a playreading, which offered a particular challenge to the researcher in terms of composition and playwriting. How can a script and soundtrack for a non-verbal, intermedial work adapt and innovate the within the formal and practical constraints of the traditional ‘playreading’? This project’s emphasis on nestling intermediality within ostensibly traditional theatrical constraints and processes draws on concepts of musicalisation, identified by Varopolou. (in Lehmann 2006:91) Certain ‘musical moments’ in the piece echoed Ross Brown’s (2010) acoustemological concepts of sonification of everyday life, and the process involved dynamic curation of ‘music under’ for emotional effect, avoiding cinematic clichés and reaching for connections between music and emotion characterized by scholars such as Juslin and Sloboda (2001) The resulting performance was a hybrid of playreading and slideshow, supported by an original soundtrack of ‘music under’ (pre-recorded, but ‘DJ’ed’ live) as well as text-driven moments where music and sound were foregrounded. Research contribution This iteration of The Empty City shows that the tradition of the playreading can be a playful space where even the multiple layers of an intermedial performance text can be represented. The Empty City was a finalist in the 2012-13 Queensland Premier’s Drama Award. A ticketed public playreading of the script was held in the Queensland Theatre Company’s Bille Brown Studio on the 28th of July 2012 alongside the other finalists.

"In 1997–98, the ASEAN (Association of Southeast Asian Nations) region suffered an unprecedented health and environmental catastrophe due to choking haze created by a massive forest !re in Indonesia. It is estimated that the total losses from the fire could be US$5–6 billion after taking into account the loss of trees and other natural resources as well as the long-term impact on human health. This unprecedented anthropogenic disaster not only created a severe health and environmental hazard but also raised a question mark about the credibility and effectiveness of the ASEAN regional grouping. Against this background, ASEAN took a number of regional initiatives to try and solve the problem and finally adopted a new treaty for regional cooperation to combat forest fire and haze in 2002. This paper assesses the future success of this agreement from the perspectives of the legal, institutional and geopolitical reality of the region. Since numerous studies have examined state responsibility for transboundary environmental harm under international law and its implications on the ASEAN haze problem, this article will not touch upon that general debate nor the remedies that are possibly available to victim states. Rather, it will focus on the ASEAN regional legal and institutional initiatives to combat the haze pollution and compare them with a similar European regional agreement. Regarding the following analysis, it is important to recognise the uncertainty arising from Indonesia’s status (presently a non-party to the Agreement). A primary indication of the future effectiveness of this agreement can be drawn from an analysis of the principles involved in this agreement, bearing in mind the inherent difficulty of enforcing norms in the international environmental legal system as a whole, and the geopolitical reality of the region."

These wordless songs were composed as music first, and soundtrack second. There is a difference. A soundtrack will always be connected with whatever it is accompanying. Music doesn’t neccessarily need to reference anything else. The Empty City transformed a picture book into a non-verbal performance combining the live and animated. Without spoken words the show would dance on the dangerous intersection of music, image and action. In both theatre and film (and this production drew on both traditions) soundtrack and music are often added on at the end when everything’s been pre-determined, a passive, responsive mode for such a powerful artform. It’s literally added in ‘post’. In The Empty City, music was present from its inception and grew with the show. It was active in process and product. It frequently led rehearsals and shaped other key decisions in virtual and live performance. Rather than tailor-make music towards pre-determined moments, independent compositions created without specific reference to narrative experimented with the creation of a flock of small musical pieces. I was interested in seeing how they flew and where they roosted, rather than having them born and raised in (narrative) captivity. The sonic palette is largely acoustic, incorporating ukulele, prepared piano and supported by a range of other elements tending towards electronica. Eventually more than seventy pieces of music were made for this show, twice the number used. These pieces were then placed in relation to the emerging scenes, then adapted in duration, texture and progression to develop a relationship with the scene. In this way, music (even when it’s synced) has a conversation with a performance, an exchange that may result in surprise rather than fulfillment of expectation. Leitmotif emerged from loops and layers, as the pieces of music ‘conversed’ with each other, rather than being premeditated and imposed. Nineteen of these tracks are compiled for this release, which finds the compositions (which progressed through many versions) poised at the moment between their fullest iteration as ‘music’ and their editing and full incorporation into a sychronised soundtrack. They are released as the began: as 'music-alone' (Kivy) In picture-book writing, the mutual interplay of text and image is sometimes referred to as interanimation , and this is the kind of symbiosis this project sought in the creation of the soundtrack. Reviewers of the noted the important role of the soundtrack in two separate productions of The Empty City: “The original score…takes centre stage” (Borhani, 2013) “…swept up in its repetition of sounds and images, like a Bach fugue” (Zampatti, 2013)

This creative work is the production of the live and animated performance of The Empty City. With a significant period of creative development and script work behind it, the team engaged in a range of innovative performance-making practices in order to realise the work onstage as a non-verbal live and animated theatre work. This intermedial process was often led by music, and involved the creation and convergence of non-verbal action, virtual performers, performing objects and two simultaneous projections of animated images. The production opened at the Brisbane Powerhouse on June 27 2013, with a subsequent tour to Perth’s Awesome Festival in October 2013. Its technical achievements were noted in the critical responses. "The story is told on a striking set of two huge screens, the front one transparent, upon which still and moving images are projected, and between which Oliver performs and occasional “real” objects are placed. The effect is startling, and creates a cartoon three dimensionality like those old Viewmaster slide shows. The live action… and soundscape sync perfectly with the projected imagery to complete a dense, intricately devised and technically brilliant whole." (The West Australian 14.10.13)

Parametric roll is a critical phenomenon for ships, whose onset may cause roll oscillations up to +-40 degrees, leading to very dangerous situations and possibly capsizing. Container ships have been shown to be particularly prone to parametric roll resonance when they are sailing in moderate to heavy head seas. A Matlab/Simulink parametric roll benchmark model for a large container ship has been implemented and validated against a wide set of experimental data. The model is a part of a Matlab/Simulink Toolbox (MSS, 2007). The benchmark implements a 3rd-order nonlinear model where the dynamics of roll is strongly coupled with the heave and pitch dynamics. The implemented model has shown good accuracy in predicting the container ship motions, both in the vertical plane and in the transversal one. Parametric roll has been reproduced for all the data sets in which it happened, and the model provides realistic results which are in good agreement with the model tank experiments.

Background Regenerative endodontics is an innovative treatment concept aiming to regenerate pulp, dentin and root structures. In the diseased or necrotic tooth, the limitation in vascular supply renders successful tissue regeneration/generation in a whole tooth challenging. The aim of this study is to evaluate the ability of vascularized tissue to develop within a pulpless tooth using tissue engineering techniques. Materials and methods A pulpless tooth chamber, filled with collagen I gel containing isolated rat dental pulp cells (DPC) and angiogenic growth factors, was placed into a hole created in the femoral cortex or into its own tooth socket, respectively. The gross, histological and biochemical characteristics of the de novo tissue were evaluated at 4 and 8weeks post-transplantation. Results Tooth revascularization and tissue generation was observed only in the femur group, confirming the important role of vascular supply in tissue regeneration. The addition of cells and growth factors significantly promoted connective tissue production in the tooth chamber. Conclusion Successful revascularization and tissue regeneration in this model demonstrate the importance of a direct vascular supply and the advantages of a stem cell approach. © 2012 John Wiley & Sons A/S.

Supply chains are the core of most industrial networks in which your business operates. They provide the pipeline through which the products and services flow from supplier to customer across each element within the business activity system. Global supply chain relationships have become the basis for many industries with an international network of firms engaged in the supply of goods and services that must be produced to quality standards in one country and delivered just-in-time for assembly or integration into further production processes in another country, frequently many thousands of miles apart. This topic examines the nature of supply chain management and their role in strategic networking. The previous learning tasks have focused on having the correct internal mechanism to effectively manage the inputs and outputs of the organisation by implementing an effective and transparent management system. This learning task takes a look at how management intent strategy and innovation are used to measure the external factors that influence the overall performance of the organisation and develop new strategies by understanding the business cycle and the people within your market environment.

This paper is presented in workshop format in order to meet the style and themes of the conference, and seeks to explore as fully as possible with participants issues, concerns and proposals around the discourse of young people and citizenship. This paper takes the position that the relationship between young people and citizenship is complex and in places contradictory, and while Ruth Lister (1998), argues for an 'inclusionary potential', a central concern is that the citizenship that young people get is as Hartley Dean (1997), suggests, at best 'ambiguous', and at its worst, 'diminished'. Under not so new Labour, the term has according to Gail Lewis (1998) re-emerged as a 'category of political articulation', imbued with the pronouncements of Charles Murray (1995) on the underclass, and Amitai Etzioni (1996), on the virtues of Communitarianism and the central assertion that in relation to young people and certain communities, 'rights have exceeded responsibilities'. This body of opinion has proved to be seductive to a government dedicated to joined up solutions in the battle against social exclusion and to the reconfiguration of the welfare state to place the onus for welfare and social provision on to individuals and communities. Those who work with young people and young people themselves may wish to be proactive in asserting the kind of citizenship they require, rights-based, expansive and supportive, rather than accept an imposed version devoid of rights but full to the brim of authoritarian measures, vindictive proposals and narrow horizons. This paper will engender debate and reflection and offer a context of the erosion of young people's rights over the last 20 years, Hartley Dean (1996), and will consider the work of T.H. Marshall (1950) in dividing citizenship into three elements: the civil element, the political element, and the social element. The paper will explore in workshop tradition, strategies and proposals for action relevant to practitioners and academics, such as the reduction in the voting age to 16.

The DeLone and McLean (D&M) model (2003) has been broadly used and generally recognised as a useful model for gauging the success of IS implementations. However, it is not without limitations. In this study, we evaluate a model that extends the D&M model and attempts to address some of it slimitations by providing a more complete measurement model of systems success. To that end, we augment the D&M (2003) model and include three variables: business value, institutional trust, and future readiness. We propose that the addition of these variables allows systems success to be assessed at both the systems level and the business level. Consequently, we develop a measurement model rather than a structural or predictive model of systems success.

Semantic perception and object labeling are key requirements for robots interacting with objects on a higher level. Symbolic annotation of objects allows the usage of planning algorithms for object interaction, for instance in a typical fetchand-carry scenario. In current research, perception is usually based on 3D scene reconstruction and geometric model matching, where trained features are matched with a 3D sample point cloud. In this work we propose a semantic perception method which is based on spatio-semantic features. These features are defined in a natural, symbolic way, such as geometry and spatial relation. In contrast to point-based model matching methods, a spatial ontology is used where objects are rather described how they "look like", similar to how a human would described unknown objects to another person. A fuzzy based reasoning approach matches perceivable features with a spatial ontology of the objects. The approach provides a method which is able to deal with senor noise and occlusions. Another advantage is that no training phase is needed in order to learn object features. The use-case of the proposed method is the detection of soil sample containers in an outdoor environment which have to be collected by a mobile robot. The approach is verified using real world experiments.

This study explores the potential use of empty fruit bunch (EFB) residues from palm oil processing residues, as an alternative feedstock for microbial oil production. EFB is a readily available, lignocellulosic biomass that provides cheaper substrates for oil production in comparison to the use of pure sugars. In this study, potential oleaginous microorganisms were selected based on a multi-criteria analysis (MCA) framework which utilised Analytical Hierarchy Process (AHP) with Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) aided by Geometrical Analysis for Interactive Aid (GAIA). The MCA framework was used to evaluate several strains of microalgae (Chlorella protothecoides and Chlorella zofingiensis), yeasts (Cryptococcus albidus and Rhodotorula mucilaginosa) and fungi (Aspergillus oryzae and Mucor plumbeus) on glucose, xylose and glycerol. Based on the results of PROMETHEE rankings and GAIA plane, fungal strains A. oryzae and M. plumbeus and yeast strain R. mucilaginosa showed great promise for oil production from lignocellulosic hydrolysates. The study further cultivated A. oryzae, M. plumbeus and R. mucilaginosa on EFB hydrolysates for oil production. EFB was pretreated with dilute sulfuric acid, followed by enzymatic saccharification of solid residue. Hydrolysates tested in this study are detoxified liquid hydrolysates (LH) and enzymatic hydrolysate (EH).
