Chip size distribution is an important quality variable not only for buyers of forest fuels, but also for chipping contractors as it influences both fuel consumption and productivity of chippers. Studies of disc chippers and of drum chippers with closed drums have shown that increased chip target length increases chipper productivity and decreases fuel consumption per ton of chips produced. For...

Design and simulation environments are tools offering contrasted benefits for discovery learning in multiple domains. However, when these domains are complex the problems that the students have to solve during their learning justify the necessity to carry out the design activity itself in groups. From the perspective of modelling and simulation in collaboration, we present DomoSim-TPC, a system...

Most aggregation queries contain both group-by and join operators, and spend a significant amount of time evaluating these two expensive operators. Merging them into one operator (the groupjoin) significantly speeds up query execution. We introduce two main equivalences to allow for the merging and prove their correctness. Furthermore, we show experimentally that these equivalences can signific...

This paper argues that parsing and productivity are causally related, the more an affix is prone to parsing in speech perception, the more productive it is likely to be. We support this claim by demonstrating a strona relationship between junctural phonotactics and affix productivity. Affixes which tend to create phonotactic junctures which facilite parsing also tend to be more productive. We s...

The MicroBooNE experiment is a liquid argon TPC experiment designed for short-baseline neutrino physics, currently running at Fermilab. Due to its location near the surface, cosmic muons can be a source of backgrounds to many analyses and having a good understanding of the cosmic rays will be very valuable for the experiment. These proceedings describe the physics motivation, setup, and perform...

The most common benchmarks for faculty productivity are derived from Medical Group Management Association (MGMA) or Vizient-AAMC Faculty Practice Solutions Center® (FPSC) databases. The Association of Pathology Chairs has also collected similar survey data for several years. We examined the Association of Pathology Chairs annual faculty productivity data and compared it with MGMA and FPSC data ...

for the ALICE TPC Collaboration. Received (received date) Revised (revised date) Using a test TPC, consisting of the ALICE TPC field cage prototype in combination with the final ALICE TPC readout and electronics, the energy loss distribution and resolution were measured for identified protons. The measurements were compared to theoretical calculations and good quantitative agreement was found w...

The ArDM experiment, a 1 ton liquid argon TPC/Calorimeter, is designed for the detection of dark matter particles which can scatter off the spinless argon nuclei. These events producing a recoiling nucleus will be discerned by their light to charge ratio, as well as the time structure of the scintillation light. The experiment is presently under construction and will be commissioned on surface ...

WIMPs (Weakly Interacting Massive Particles) are considered the main candidates for Cold Dark Matter. The ArDM experiment aims at measuring signals directly induced by WIMPs in liquid argon. A 1-ton prototype is currently developed with the goal of demonstrating the feasibility and performance of a detector with such a large target mass. ArDM aims at acting as a liquid argon TPC and additionall...

あらまし 移動無線通信では,フェージング,シャドウイングや伝搬損失によって受信レベルが変動するため品 質劣化が発生する.一つの基地局に多数の送受信アンテナを集中させるよりも,それらをセル内に分散配置するこ とにより品質劣化を軽減できる.これまで,筆者らは,周波数分割多元接続(FDMA)セルラー環境でのマルチセル 下りリンクを対象に最大比送信(MRT)ダイバーシチを用いる分散アンテナネットワーク(DAN)について検討し,送 信ダイバーシチに参加するアンテナ数を増加させるとダイバーシチ効果が増大し,周波数利用効率が向上すること を示してきた.しかし,送信ダイバーシチを用いてもフェージング,シャドウイングや伝搬損失による受信電力の 変動が残留する.これを抑圧する技術に送信電力制御(TPC)がある.DAN に TPC を導入した時の周波数利用効率に ついては筆者らの知る限り,これまで検討が行...
