Bio-archaeological studies can contribute significantly to understanding the economic interactions between cities and their hinterland. In Pompeii, where research has often been intramurally focussed, analysis of biological remains is often confined to bones and macro-botanicals consumed as foodstuffs. Charcoal, if collected, often remains unexamined, and yet this material is key to understanding the fuel economy of a city. This study has two goals: first, to describe an efficient method for charcoal sampling and analysis in a dense urban environment using only dry-sieved charcoals above 5 mm; and, second, in doing so, to demonstrate the dependent relationship between Pompeii and its hinterland for the provision of fuel in a case study from the House of the Vestals. A pilot study of 25 contexts from six ‘rooms’ and 750 charcoal fragments was followed by an extended study of 62 contexts over 14 rooms (a total of 1579 charcoal fragments). The extended results identified only two further (minor) taxa (represented by only three fragments). The most important wood identified was beech (Fagus sylvatica), which constituted 50–75 per cent of the fuel supply, depending on the time period. Beech grows preferentially above about 900 m in central and southern Italy. Pompeii lies at 30 m altitude with the nearest mountain areas at least 15 km away. The study suggests that a methodology that relies on collection of charcoal from routine dry sieving (5 mm grid), in soils where this is possible, can provide robust results in a cost effective manner in an urban setting.

Steel Catenary Risers

Recently turret-Moored FPSOs have been used in many deep water developments worldwide, with consideration of disconnectable turrets for harsh environment applications. This trend makes the interactions between FPSO and risers system more important. Further, Steel Lazy Wave Risers (SLWR), which is a compliant variant of the mostly commonly used Steel Catenary Risers (SCR), is becoming an attractive riser option. The paper provides a review of the various riser systems that can be considered for turret-moored FPSOs, and specific emphasis on Steel Lazy Wave Risers. A detailed case study of Steel Lazy Wave Risers for a typical turret moored FPSO with disconnectable turret is presented. This system is described in terms of design and functionalities, the fabrication and installation methods are presented. The case study shows clearly that SLWR are an attractive alternative to be used for FPSO with disconnectable turret and is very efficient to fabricate and install in a very cost effective manner. Pros and Cons for SLWR are discussed, with consideration of the particular challenges of turret-moored FPSOs with large floater motions, hang-off geometry constraints at turret, hang-off loads, riser interferences, risers pre-installation, and turret disconnection constraints.

This study investigates ‘Manufacturing design for productivity’ surveying a case study of an existing assembly line for Turbo charger Core. The main aim is to investigate the possibilities of operational improvement by reducing number of stations in assembly line in a cost-effective manner by reducing the number of grippers used in complete assembly layout. An assembly line is selected for the case study. An existing assembly is redesigned by using the concepts of methods engineering. Then both cases are analyzed and discussed in terms of their output ability and manufacturing time. After the analysis of redesigned assembly layout it is observed that we can reduce average Operation time by 15 % at the end of this study. At the end of this project, we increased the production quantity from 824 to 955 products. Because efficiency of station work has increased with the redesigned assembly line with aid of dual arm robot. The new assembly line reduces the station idle time and increases its efficiency in operation. The existing assembly line was covering 8 m2 it got reduced to 4 m2 approximately in optimized layout. It is observed 15.89% productivity increased for the same period of time. By the standardization and the elimination of the station operations, and reducing the labor cost the company could increase its competitive strength through the optimized layout design.

Every system, when connected to a network, is susceptible to threat of being hacked. It is important to protect all systems of an organization in real-time in a cost-effective manner. This article presents a well-designed and integrated database for risk management data using a dashboard interface in real-time risk that makes it easy for risk managers to reach a understanding the level of threats to be able to apply right controls to mitigate them. In this article, a case study of a data center for a statistical management institute is presented that proposes the calculation of total risk at the organization level by using the proposed risk database. A digital dashboard is also designed for presenting the risk level results so that decision makers can apply counter measures. The risk level on a dashboard viewer makes it easy for decision maker to understand the overall risk level at the statistics data center and assists in the creation of a tool to follow-up risk management since the time a threat hits until the time of its mitigation.

Abstract The provision and maintenance of road infrastructure is a major global business, consequently it is essential that road maintenance services are provided in the most cost effective manner. Without regular maintenance, roads can rapidly fall into disrepair, preventing realization of the longer term impacts of road improvements on development, such as increased agricultural production and growth in school enrollment, which is of particular importance for a network of local (access) roads. Inadequate local roads maintenance in Albania is proposed to be solved by implementing performance based maintenance approach for which the costing exercise is presented within the paper.

The presence of vast communication and information nowadays necessitates the need for a system to readily access and transfer data. The study aimed to develop records archiving and document repository to overcome the barrier of server client method of deploying the documents from one place to another and easier data access to its stakeholders. The Sorsogon State College in the Philippines has four campuses which are located strategically in four municipalities of Sorsogon province. Their distance from each other sometimes causes a problem particularly along communication and real time updates. General User Interface (GUI) of the application has been built on top of all web-enabled computers and even to the mobile devices, so it requires only installed web browsers to render the GUI onto their devices regardless of its platform and specifications. The installation of web-based archiving and repository on its main campus enables satellite campuses to connect to the college private server in a cost-effective manner through virtual private network that connects on top of the Internet service provider. This study overcomes the vulnerability of security by means of allowing user credentials to login at the private server using a 1024 bit Rivest-Shamir-Adleman (RSA) private/public key exchange and 256-bit Advance Encryption System (AES) encryption through its virtual private network. Contents of the uploaded files were being encrypted at 128-bit to prevent intranet users from sneaking the file contents. Keywords - ICT, document archive, web, GUI, developmental research, Sorsogon City, Philippines,

Identifying hazardous locations on highways is an essential step for safety improvement programs and projects since it provides decision makers with a logical and scientific basis for the allocation of resources in a cost-effective manner. There have been numerous studies conducted to develop suitable methodologies for identifying hazardous locations; however, most of them have not considered spatial interactions which are inherent in traffic accidents. In this paper, we use the GIS-based geographically weighted regression (GWR) that can model crash outcomes and identify hazardous locations on expressways while reflecting the effect of spatial dependency and heterogeneity on the outbreak of traffic accidents. This method has been applied to a case study at Gyeongbu Expressway in Korea with 3-year crash data. Koenker's studentized Bruesch-Pagan and Moran’s I tests confirm the spatial relationship among crash data. The findings indicate that it is proper to model crash frequency with GWR for identifying hazardous locations.

Abstract Coping with changing requirements by means of introducing design margins may result in overdesign. In this paper, we present a design optimization method for minimizing overdesign by exploiting additive remanufacturing. Our problem formulation makes use of recently defined constituents of design margins: buffer and excess. The proposed method can be used to obtain a set of design decisions for different changing requirement scenarios. We demonstrate it using a turbine rear structure design problem where changes in the temperature loads are met by depositing different types of stiffeners on the outer casing. The results of the case study are visualized in a tradespace, which allows for comparison between sets of optimal, flexible, and robust designs. Results show that the optimized set of design decisions balances flexibility and robustness in a cost-effective manner.

Anthropogenic activities often lead to the degradation of valuable natural habitats. Many efforts have been taken to counteract this degradation process, including the mitigation of human-induced stressors. However, knowing-doing gaps exist in stakeholder’s decision-making of prioritizing sites to allocate limited resources in these mitigation activities in both spatially aggregated and cost-effective manner. In this study, we present a spatially explicit prioritization framework that integrates basic cost effectiveness analysis (CEA) and spatial clustering statistics. The advantages of the proposed framework lie in its straightforward logic and ease of implementation to assist stakeholders in the identification of threat mitigation actions that are both spatially clumped and cost-effective using innovative prioritization indicators. We compared the utility of three local autocorrelation-based clustering statistics, including local Moran’s I, Getis-Ord Gi*, and AMOEBA, in quantifying the spatial aggregation of identified sites under given budgets. It is our finding that the CEA method produced threat mitigation sites that are more cost-effective but are dispersed in space. Spatial clustering statistics could help identify spatially aggregated management sites with only minor loss in cost effectiveness. We concluded that integrating basic CEA with spatial clustering statistics provides stakeholders with straightforward and reliable information in prioritizing spatially clustered cost-effective actions for habitat threat mitigation.

Three levels of planning can be distinguished in grassland farming: strategic, tactical and operational. The purpose of strategic planning is to achieve a sustainable long-term fit of the farm business with its physical, social and financial environment. In pastoral farming, this essentially means developing plans that maximise and best match pasture growth with animal demand, while generating sufficient income to maintain or enhance farm resources and improvements, and attain personal and financial goals. Strategic plans relate to the whole farm business and are focused on the means to achieve future needs. They should be routinely (at least annually) reviewed and monitored for effectiveness through key performance indicators (e.g., Economic Farm Surplus) that enable progress toward goals to be measured in a timely and cost-effective manner. Failure to link strategy with control is likely to result in unfulfilled plans. Keywords: management, performance
