A proportional fairness algorithm with QoS provision in downlink OFDMA systems
No full textIn this letter, we formulate a downlink packet scheduling problem for proportional fairness in orthogonal frequency division multiple access with frequency division multiple access (OFDMA) systems to derive necessary conditions for optimality, which results in efficient subcarrier and power allocation algorithms. Simulation results reveal that our proposed algorithm achieves the tradeoff between system throughput and fairness
Development of TD Website and Repository
No full textSEAFDEC, an Inter-Governmental Organization plays an important role in promotion of sustainable development of fisheries and aquaculture in the Southeast Asian Region for more than four decades. Cooperation with other regional and international organizations have been recognized through several important events such as Millennium Conference in 2001 and ASEAN-SEAFDEC Conference in 2011. Since 1990s, internet have been introduced worldwide, where information technology becomes important as a part of human life including education, economic, social and politicsand so on. Development of high speed internet creates a new communication system and support living style including works and activities such as public relations, multi-media production, publication etc., especially information dissemination and website which are technologies for communication between internal and external organization as well as in developing management system for efficiencies. The objective of this paper is to enhance SEAFDEC visibility by developing the information and dissemination system which developed new TD website in 2017.
In this regards, TD established Southeast Asian Fisheries Development Center, Training Department Institutional Repository (STIR), which is the official digital repository of scholarly, research and technical information of the Department to download all information materials using open source software named the DSpace.
In this paper, author considers the importance of information technology for introducing SEAFDEC/TD activities and improving access to SEAFDEC/TD technical/scientific articles was expressed via the website. In this regards, the author introduced for developing of the TD website and Repository to increase public relation and increase TD’s visibility as well as point out constrains of its development that requires the strengthening and cooperation within the Training Department of SEAFDEC

Coordinating multiple concurrent negotiations
No full textTo secure good deals, an agent may engage in multiple concurrent negotiations for a particular good or service. However for this to be effective, the agent needs to carefully coordinate its negotiations. At a basic level, such coordination should ensure the agent does not procure more of the good than is needed. But to really derive benefit from such an approach, the agent needs the concurrent encounters to mutually influence one another (e.g. a good price with one opponent should enable an agent to negotiate more strongly in the other interactions). To this end, this paper presents a novel heuristic model for coordinating multiple bilateral negotiations. The model is empirically evaluated and shown to be effective and robust in a range of negotiation scenarios
Reasoning about commitments in multiple concurrent negotiations
No full textAutomated negotiation by software agents is a key enabling technology for agent mediated e-commerce. To this end, this paper considers an important class of such negotiations - namely those in which an agent engages in multiple concurrent bilateral negotiations for a good or service. In particular, we consider the situation in which a buyer agent is looking for a single service provider from a number of available ones in its environment. By bargaining simultaneously with these providers and interleaving partial agreements that it makes with them, a buyer can reach good deals in an efficient manner. However, a key problem in such encounters is managing commitments since an agent may want to make intermediate deals (so that it has a definite agreement) with other agents before it gets to finalize a deal at the end of the encounter. To do this effectively, however, the agents need to have a flexible model of commitments that they can reason about in order to determine when to commit and to decommit. This paper provides and evaluates such a commitment manager and integrates it into the negotiation model
Energy potential from the anaerobic digestion of food waste in municipal solid waste stream of urban areas in Vietnam
No full textAnaerobic digestion (AD) was introduced in Vietnam more than 10 years ago, but at a small scale to deal with agricultural wastes, manure, etc. Despite its many advantages, AD does not yet make a significant contribution to resolving Vietnams urban waste issues due to a lack of information, data and experience. This paper, using an energy model of food waste digestion, provides a usable source of information regarding energy potential of food waste generated from urban areas in Vietnam in forms of electricity, heat, and upgraded biogas under two different scenarios. Results show that if food waste is separated from the municipal solid waste (MSW) stream and sent to AD plants, total available energy equivalent each day is about 19, 20 and 45 GWh in 2015, 2020, and 2025, respectively. This could contribute between 2.4 and 4.1 % of the electricity demand of Vietnam, as well as double this amount of energy in the form of heat. Alternatively, upgraded biogas could contribute approximately 2.2–4.7 % of fuel consumption for transportation. This suggests AD is a promising method to treat MSW in cities, especially when considering the problematic aspects of other current waste disposal methods such as: landfilling, composting and, incineration
Multi-scale Bushfire Detection from Multi-modal Streams of Remote Sensing Data
No full textBushfire is a destructive force that would change the course of a country and even the Earth. They are causing casualties and affect the quality of life of millions of people. Governments are calling for remote sensing methods to monitor and detect active bushfires around-the-clock. To fulfill this call, we develop a remote sensing framework on top of imagery satellite streams to monitor and detect bushfire timely before beyond control. However, detecting bushfires from satellite images needs to take into account several aspects including spatial pattern of fire-positive pixels, temporal dependencies, spectral correlation between channels, and adversarial effects. In this article, we propose a multi-scale deep neural network model that combines both satellite images and weather data for detecting and locating bushfires at both image and pixel level. We illustrate that the weather information with careful spatio-temporal alignment can be utilised to augment imagery data. Experiments on real-world datasets show that the proposed model is better than the baselines with 93.4% accuracy and detects bushfires 1.2 times faster. It is also robust to the effects of cloud and night-time.Full Tex
