Spark and Couchbase– Augmenting the Operational Database with SparkMatt Ingenthron
How do NoSQL Document-Oriented Databases like Couchbase fit in with Apache Spark? This set of slides gives a couple of use cases, shows why Couchbase works great with Spark, and sets up a scenario for a demo.
IN THIS SUMMARY
CEOs face a life that not many people have the opportunity to experience. Not only are they in a position to effect great change, but as leaders of companies, they also have an incredible amount of responsibility and accountability on their shoulders. Adapting to change and navigating a company through both success and failure can be hugely challenging, yet there are CEOs who seem to do it with ease and confidence. What are their secrets? In The New Secrets of CEOs, authors Steve Tappin and Andrew Cave explore this very question and delve into the mindset of a CEO. After conducting hundreds of interviews with CEOs, Tappin and Cave present a broad spectrum of executive insights, thoughts on what drives them, and how they operate.

In the age of good – how good is your organisation? by Stephen PainAddison Group
Stephen J Pain, independent consultant and Visiting Fellow, Henley Business School, looks at how the economic downturn has forced corporates to repriortise their values in rebuilding the reputation at The Group seminar on Measuring corporate brand reputation, 18 May 2010
How you can use game mechanics to increase user engagement, from market research surveys to controlling traffic speed. Cheskin Added Value's Leigh Marriner presented this fascinating lecture at Stanford University.

概要:リソース効率に優れた特徴点マッチングのための軽量なアーキテクチャ「XFeat(Accelerated Features)」を提案します。手法は、局所的な特徴点の検出、抽出、マッチングのための畳み込みニューラルネットワークの基本的な設計を再検討します。特に、リソースが限られたデバイス向けに迅速かつ堅牢なアルゴリズムが必要とされるため、解像度を可能な限り高く保ちながら、ネットワークのチャネル数を制限します。さらに、スパース下でのマッチングを選択できる設計となっており、ナビゲーションやARなどのアプリケーションに適しています。XFeatは、高速かつ同等以上の精度を実現し、一般的なラップトップのCPU上でリアルタイムで動作します。
セル生産方式におけるロボットの活用には様々な問題があるが,その一つとして 3 体以上の物体の組み立てが挙げられる.一般に,複数物体を同時に組み立てる際は,対象の部品をそれぞれロボットアームまたは治具でそれぞれ独立に保持することで組み立てを遂行すると考えられる.ただし,この方法ではロボットアームや治具を部品数と同じ数だけ必要とし,部品数が多いほどコスト面や設置スペースの関係で無駄が多くなる.この課題に対して音𣷓らは組み立て対象物に働く接触力等の解析により,治具等で固定されていない対象物が組み立て作業中に運動しにくい状態となる条件を求めた.すなわち,環境中の非把持対象物のロバスト性を考慮して,組み立て作業条件を検討している.本研究ではこの方策に基づいて,複数物体の組み立て作業を単腕マニピュレータで実行することを目的とする.このとき,対象物のロバスト性を考慮することで,仮組状態の複数物体を同時に扱う手法を提案する.作業対象としてパイプジョイントの組み立てを挙げ,簡易な道具を用いることで単腕マニピュレータで複数物体を同時に把持できることを示す.さらに,作業成功率の向上のために RGB-D カメラを用いた物体の位置検出に基づくロボット制御及び動作計画を実装する.
This paper discusses assembly operations using a single manipulator and a parallel gripper to simultaneously
grasp multiple objects and hold the group of temporarily assembled objects. Multiple robots and jigs generally operate
assembly tasks by constraining the target objects mechanically or geometrically to prevent them from moving. It is
necessary to analyze the physical interaction between the objects for such constraints to achieve the tasks with a single
gripper. In this paper, we focus on assembling pipe joints as an example and discuss constraining the motion of the
objects. Our demonstration shows that a simple tool can facilitate holding multiple objects with a single gripper.
