This chapter describes the environmental assessment of hybrid broadband satellite systems using the latest lifecycle analysis (LCA) techniques. The BATS (Broadband Access via integrated Terrestrial and Satellite systems) project has based its assessments on the GHG Protocol approach, with the ETSI LCA and ITU-T L.1400 methodology series used to provide more detailed guidance where this is needed. This assessment has shown that it is possible to employ cut off rules and approximations to reduce the cost or length of an assessment and still provide useful results. The assessment has shown that, using current technology for the IUG and satellite modem, the carbon footprint of a hybrid broadband satellite network can be comparable with that of a terrestrial (fixed or mobile) network for an equivalent level of service when the use of low-power states are considered. The implementation of these states in future commercial systems should be explored. Finally ways are suggested to reduce the environmental impact of hybrid broadband satellite systems, in particular by reducing energy (power) consumption during the use stage. Key issues include how to compare the energy efficiency of a hybrid broadband satellite network with other methods of broadband delivery, how to accurately assess the carbon embodied during the production of the equipment, and how to use low-power modes to reduce energy consumption without affecting the response time or quality of experience (QoE).

Stable Control

This research aims to develop a method to reduce energy consumption when controlling an inverted pendulum system that is affected by external interference. In this paper, the authors use the quasi time-optimal control law and add on an inverted pendulum an auxiliary pendulum to absorb the energy of the external interference effects, to reduce the cost of controlling the energy stable inverted pendulum while ensuring system quality. The quality of the method is demonstrated through simulation results. The effectiveness of this method is shown by comparison with the method of no damping.

Reduce Energy Consumption

An ad hoc network is a dynamically wireless mobile network. It can construct network automatically and quickly. Because of the importance and universality of application, ad hoc network is trend to become a research hotspot. It is necessary to research an effective routing protocol so as to be adapted to mobility of terminal equipment and to provide the reliable data transmission. This paper firstly studied and analyzed existed routing protocols, and simulated these protocols. Finally we proposed an improved routing protocol based on DSR and AODV, in which we divided all nodes into different clusters, and every cluster has only one cluster head. These nodes within the same cluster communicate using DSR protocol while those nodes in the different cluster communicate through the cluster head using AODV protocol. So, the data packet can go through the shortest link, thus it can decrease transmission delay and reduce energy consumption remarkably. Finally we use the network simulation software named NS2 to simulate experiment result. The results show that this protocol can improve the performance and the service quality of the network.

AbstractAnalysis of patent solutions and research of scientific-research literature in the field of grain processing with technical devices, e.g. kneaders in relation to the quality and digestibility in feed doses of the obtained syrup for the development of beef and dairy cattle was performed. Assumptions of the development trend of feed production, new technologies based on grain, which allow improvement of the quality of feed and reliability of technological lines of animal nutrition, reduce energy consumption, reduce losses were presented. In this regard, reduction of the cost of producing feed compared for example to the production of fodder beet or sugar beet from 1.5 to 2 times is possible.

The Cost

The overwhelming growth of resource-intensive and latency-sensitive applications trigger challenges in legacy systems of mobile cloud computing (MCC) architecture. Such challenges include congestion in the backhaul link, high latency, inefficient bandwidth usage, insufficient performance, and quality of service (QoS) metrics. The objective of this study was to find out the cost-efficient design that maximizes resource utilization at the edge of the mobile network which in return minimizes the task processing costs. Thus, this study proposes a cooperative mobile edge computing (coopMEC) to address the aforementioned challenges in MCC architecture. Also, in the proposed approach, resource-intensive jobs can be unloaded from users' equipment to MEC layer which is potential for enhancing performance in resource-constrained mobile devices. The simulation results demonstrate the potential gain from the proposed approach in terms of reducing response delay and resource consumption. This, in turn, improves performance, QoS, and guarantees cost-effectiveness in meeting users' demands.

This paper examines the perceptions of small firms from eight OECD countries towards their national climate for innovation, and the perceived importance of outsiders in assisting them with innovation projects. A total of 505 firms were surveyed, each had an innovation they were seeking to commercialise. Key issues examined were the firm's senior managers' perceptions of how supportive their country was to innovators in relation to government policy, the cost of doing business and the quality of communications infrastructure. Also examined was the ease of access to markets, skilled labour, research centres and external financing. The managers were also asked to indicate how much value they placed on outsiders such as accountants, venture financiers, customers, suppliers, lawyers and others in relation to their strategic decision making over commercialisation activities. Differences were found between the country sub-samples using discriminant analysis. However, the similarities between these firms suggest more commonality than differences.

By transforming patterns of travel and work around the world, the COVID-19 pandemic is accelerating the transition to renewable energy and the decline of fossil fuels. Lockdowns brought car commuting and plane travel to a near halt, and the mass experiment in which white-collar employees have been working from home may permanently reduce energy consumption for business travel. Renewable energy and electric vehicles were already gaining market share before the pandemic. Under pressure from investors, major energy companies have started writing off fossil fuel reserves as stranded assets that are no longer worth the cost of extracting. These shifts may indicate that “peak oil demand” has arrived earlier than expected.

The accuracy in administering the diagnosis code was the important matter for medical recorder, quality of data was the most important thing for health information management of medical recorder. This study aims to know the coder competency for accuracy and precision of using ICD 10 at X Hospital in Pekanbaru. This study was a qualitative method with case study implementation from five informan. The result show that medical personnel (doctor) have never received a training about coding, doctors writing that hard and difficult to read, failure for making diagnoses code or procedures, doctor used an usual abbreviations that are not standard, theres still an officer who are not understand about the nomenclature and mastering anatomy phatology, facilities and infrastructure were supported for accuracy and precision of the existing code. The errors of coding always happen because there is a human error. The accuracy and precision in coding very influence against the cost of INA CBGs, medical and the committee did most of the work in the case of severity level III, while medical record had a role in monitoring or evaluation of coding implementation. If there are resumes that is not clearly case mix team check file needed medical record the result the diagnoses or coding for conformity. Keywords: coder competency, accuracy and precision of coding, ICD 10
