TL;DR: Simulations demonstrate the energy efficiency of the proposed algorithms and the tradeoff between energy saving and coverage guarantee and centralized and decentralized implementations are investigated.
Abstract: The explosive development of ICT (information and communication technology) industry has emerged as one of the major sources of world energy consumption. Therefore, this paper concerns about the BS (base station) energy saving issue, for most energy consumption of the communication network comes from the BSs and the core network. Particularly, we consider dynamically turning off certain BSs when the network traffic is low. Centralized and decentralized implementations are investigated. Simulations demonstrate the energy efficiency of the proposed algorithms and the tradeoff between energy saving and coverage guarantee.

TL;DR: In this paper, a space and time domain automatic classification technique was developed and applied to single event upsets (SEUs) of 130nm SRAM under quasi-mono energetic neutron irradiation at TSL and CYRIC.
Abstract: Recent diversity in multicell upset (MCU) of CMOS SRAMs are reviewed and scaling effects are discussed. Space and time domain automatic classification techniques are developed and applied to single event upsets (SEUs) of 130nm SRAM under quasi-mono energetic neutron irradiation at TSL and CYRIC. Tests show very high dependency of MCU features on data patterns, typically \"All `0'/`1'\" and checkerboard. Three error propagation categories with 41 modes inherent in device architectures are identified. Novel MCU features, in which errors can be corrected by rewriting but Idd increases stepwise depending on MCU multiplicity, are identified. With \"All `0'/`1'\" pattern, ratio of double bit error is found to be even higher than that of single bit errors. The majority of the double bit error is in nearest neighborhood (NN) position along word line (WL). Underlining basic mechanism can be either charge collection-diffusion or parasitic bipolar actions. But most features can be elucidated only fully by a novel MCU mechanism MCBI (multi-coupled bipolar interaction) proposed by the authors, giving clues for SEU tolerant sub-100nm design

TL;DR: In this paper, a method for hand printed Kanji character classificatin is proposed, based on extraction of directional line segments and partitioning of the character frame area, a feature vector that represents the distribution of strokes is generated and matched with average vectors in a dictionary.
Abstract: A method for handprinted Kanji character classificatin is proposed in this paper. After extraction of directional line segments and partitioning of the character frame area, a feature vector that represents the distribution of strokes is generated and is matched with average vectors in a dictionary.
