title: An efficient travel scheduling for Electric Vehicles based on Car-Sharing service abstract: Electric vehicles (EV) have become popular in the past several years. However, the short travel distance and the long charge time are big problems. In this study, we plan to adapt EVs to long distance travel by using car-sharing service. The idea is allowing driver change his/her EV to other full charged EV before the current EV run out of battery. The target of our proposed method is to find an optimal car-sharing schedule in a multiple drivers/EVs environment. language of the presentation: Japanese 発表題目: カーシェアリングに基づいたEVの効率的運用スケジューリングの検討 発表概要: 近年，電気自動車（EV，Electric Vehicle）は徐々に普及するようになったが，EVの短い航続距離と長い充電時間はさらなる普及に向けた課題となっている．本研究では，カーシェアリングの仕組みを利用しユーザが電力残量が少ないEVを他のEVに乗り換えることで長距離走行を実現する．提案手法では，多数のカーシェアリング利用者を対象に，EV乗換スケジューリングを行う． | ||

title: Paper introduction "CPU-Assisted GPGPU on Fused CPU-GPU Architectures"
abstract: This paper presents a novel approach to utilize the CPU resource to facilitate the execution of GPGPU programs on fused CPU-GPU architectures. In our model of fused architectures, the GPU and the CPU are integrated on the same die and share the on-chip L3 cache and off-chip memory, similar to the latest Intel Sandy Bridge and AMD accelerated processing unit (APU) platforms. In our proposed CPU-assisted GPGPU, after the CPU launches a GPU program, it executes a pre-execution program, which is generated automatically from the GPU kernel using our proposed compiler algorithms and contains memory access instructions of the GPU kernel for multiple threadblocks. The CPU pre-execution program runs ahead of GPU threads because (1) the CPU pre-execution thread only contains memory fetch instructions from GPU kernels and not floating-point computations, and (2) the CPU runs at higher frequencies and exploits higher degrees of instruction-level parallelism than GPU scalar cores. We also leverage the prefetcher at the L2-cache on the CPU side to increase the memory traffic from CPU. As a result, the memory accesses of GPU threads hit in the L3 cache and their latency can be drastically reduced. Since our pre-execution is directly controlled by user-level applications, it enjoys both high accuracy and flexibility. Our experiments on a set of benchmarks show that our proposed preexecution improves the performance by up to 113% and 21.4% on average. language of the presentation: Japanese

title: A Wi-Fi Offloading Method Based on Prefetching
abstract: Mobile data traffic is growing at a drastic rate. This growth is due to the spreading of the use of smartphones, the increasing number of subscribers, and the rapid development of mobile broadband. This explosive growth of the number of mobile users causes immense pressure on the limited spectrum of cellular networks (3G networks), and the deterioration in the quality of wireless communication. To cope with this problem, mobile network operators deploy Wi-Fi access points(Wi-Fi APs) to offload the traffic from 3G networks to Wi-Fi. However, since the coverage of a Wi-Fi AP is relatively small and the number of Wi-Fi APs are limited, Wi-Fi connectivity is far from ubiquitous. There are some existing offloading methods that postpone communication requests from applications in 3G networks until the user moves to a Wi-Fi area in the near future. These methods, however, cause the poor performance of delay sensitive applications like web browsing and streaming of video and audio. To address this problem,we propose a Wi-Fi offloading method based on prefetching. Our method predicts the contents that will be requested by the user in the 3G networks, and prefetches them in advance when Wi-Fi connectivity is available. Thus if the prefetched contents are requested after the user moves from the Wi-Fi area to a 3G area, the user can instantly access the contents without communication over 3G networks. In this presentation, I will talk about the background of our research, related studies, and our proposed method.After that, I will show what has been done so far, and present my research plan. language of the presentation:Japanese 発表題目:プリフェッチに基づいたWi-Fiオフローディング手法の提案 発表概要:スマートフォンの普及，携帯電話利用者の増加，モバイル・ブロードバンドの普及によりモバイル・データ・トラフィックが急増している．これにより，携帯電話回線（3G回線）の負荷が高まり，それに伴う通信品質の低下が危惧されている． このような状況から，3G回線の負荷をWi-Fiネットワーク側に逃がすWi-Fiオフローディングが注目されている．しかし，1つのWi-Fiアクセスポイント（Wi-Fi AP）のカバレッジは狭く，またその設置台数も少ないため，Wi-Fiオフローディングの機会が少ないという問題がある． この問題に対して，既存研究では，3Gエリアで発生した通信要求を，近い将来Wi-Fiエリアに入るまで遅延させることで，オフローディングの機会を拡大する方法を提案するものがある． しかしこの方法は，高い応答性が求められるコンテンツの閲覧に対しては適用が困難である．この問題を解決するために，本研究では，プリフェッチに基づいたWi-Fiオフローディング手法を提案する． 提案手法では，ユーザがWi-Fiエリアに滞在中に，そのエリアを出た後に3Gエリアで閲覧する可能性があるコンテンツを予測し,事前にダウンロード（プリフェッチ）する．これにより，ユーザが3Gエリアに移動した後，プリフェッチ済みのコンテンツが要求された場合に，3G回線を利用せずに即座にコンテンツの提示が可能となる． スマートフォンにとってバッテリは最重要のリソースであるため,この手法を提案するにあたって消費電力に対する制約を設ける.そして制約では,あるコンテンツをプリフェッチと,プリフェッチできなかった文を3G回線で取得した場合の消費電力量の合計が,同じコンテンツを3G回線のみで取得した場合の消費電力量を超えないようにする. また提案手法では,プリフェッチするコンテンツを,その容量と閲覧確率より導き出したオフローディング期待を元に評価する.そして,オフローディング期待値が最大になるようなコンテンツの集合をプリフェッチすることによって,オフローディング量を最大化する. 本発表では，研究背景，関連研究，提案手法，および進捗と今後の課題について述べる． | ||

title: The Effect of Electronic Self-Monitoring on Weight Loss and Dietary Intake: a Randomized Behavioral Weight Loss Trial
abstract:Technology may improve self-monitoring adherence and dietary changes in weight loss treatment. Our study aimed to investigate whether using a personal digital assistant (PDA) with dietary and exercise software, with and without a feedback message, compared to using a paper diary/record (PR), results in greater weight loss and improved self-monitoring adherence. Healthy adults (N = 210) with a mean BMI of 34.01 kg/m2 were randomized to one of three self-monitoring approaches: PR (n = 72), PDA with self-monitoring software (n = 68), or PDA with self-monitoring software and daily feedback messages (PDA+FB, n = 70). All participants received standard behavioral treatment. Self-monitoring adherence and change in body weight, waist circumference, and diet were assessed at 6 months; retention was 91%. All participants had a significant weight loss (P < 0.01) but weight loss did not differ among groups. A higher proportion of PDA+FB participants (63%) achieved >= 5% weight loss in comparison to the PR group (46%) (P < 0.05) and PDA group (49%) (P = 0.09). Median percent self-monitoring adherence over the 6 months was higher in the PDA groups (PDA 80%; PDA+FB 90%) than in the PR group (55%) (P < 0.01). Waist circumference decreased more in the PDA groups than the PR group (P = 0.02). Similarly, the PDA groups reduced energy and saturated fat intake more than the PR group (P < 0.05). Self-monitoring adherence was greater in the PDA groups with the greatest weight change observed in the PDA+FB group. language of the presentation: Japanese | ||
