ABSTRACT Energy storage technologies that are connected to medium- or low-voltage distribution systems are referred to as Distributed Energy Storage (DES). DES are becoming more common as the storage technologies are becoming cheaper. Energy stored on the distribution system, whether it is generated by Distributed Generation (DG) or central generation units, could provide crucial services (such as load leveling, automatic generation control, smoothing fluctuations in intermittent sources, etc) to electricity suppliers. The need of the hour is to effectively utilize these distributed storage devices so as to lower operating costs while offering aforementioned services. In contemporary literature, while DES have been considered, they could only be charged/discharged from/to the grid. The current work marks a significant departure with the goal of allowing storage devices to charge each other. Such battery-to-battery energy transfer is useful for instance in scenarios when generators cannot be run for certain reasons, or that it might cause too much load on the network, if the storage devices were to be charged directly from the power grid. Simulation results on a 30-bus IEEE benchmark system validate the benefits of inter-storage charge transfers.

ABSTRACT In the theory of linear viscoelasticity, creep and relaxation functions are the important delay kernels in the stress-strain relations. Quite recently, a creep function power law has been obtained experimentally for an isolated living cell (on the scale of the cell). The corresponding form of the relaxation function is derived using the interconversion formula. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

A new report published by 23 researchers at NUPI and sister institutes in all ten ASEAN countries analyses the consequences of climate change and climate policy for international affairs in ASEAN. Both climate change and climate mitigation are likely to affect international affairs in ASEAN—in ways that are both good and bad—for example through forced migration, strains on food production, accelerated dam construction on the region’s international rivers on reduced dependency on fossil fuel imports.

The new report published by NUPI, jointly contributed by its partner institutes in all ten ASEAN countries, analyses the consequences of climate change and climate policy toward international affairs in ASEAN. Both climate change and climate mitigation are likely to affect international affairs in ASEAN—in ways that are both good and bad—for example through forced migration, strains on food production, accelerated dam construction on the region’s international rivers on reduced dependency on fossil fuel imports. Major analysis and assessment in term of global energy transition, international climate-policy commitments of ASEAN countries, ASEAN's role on climate and energy policy as well as recommendations were put forward.

This study examines the implications of climate change for international affairs in Southeast Asia and for ASEAN as a multilateral organization. Climate change and efforts to mitigate climate change give rise to major risks as well as opportunities in international affairs. It is therefore in the interest of all countries to be aware of the risks and prepare for them, and the overarching purpose of this study is to support ASEAN and its member states in this area. Given Southeast Asia’s complex geography—with numerous archipelagoes, long coastlines, intricate borders, and great-power neighbors—climate change is especially likely to affect interstate relations in the region.Climate change may impact on international affairs among the ASEAN countries at several levels. Firstly, changing climatic conditions may affect interstate relations through humanitarian crises, migration, and/or the need for greater imports of vital goods. Secondly, reducing greenhouse gas emissions requires international coordination and cooperation. Thirdly, the global energy transition driven by climate policy may lead to an altered geopolitical situation in the world, including ASEAN.

Remote sensing is a technique which demands a large amount of analysis on data which may have been captured from a variety of sources. Common sources range from aerial vehicles equipped with scanning devices to sensors attached to satellites in space missions. The data acquisition, however, is commonly subject to the interference of external factors, such as particles in the atmosphere and clouds, which may lead to noise in the data. This paper presents a technique to detect the presence of such artifacts, as observed in some digital elevation model data, and an algorithm to patch them. A case study on the second version of the ASTER GDEM shows that the proposed algorithm is effective in the detection and patching of vertical artifacts and that it can be applied to different data sets in the realm of digital elevation models.
