An open architecture manufacturing system pursues to integrate manufacturing components on a single platform. Therefore, a particular component can be easily added and/or replaced. In this paper, a modular and object-oriented approach for the PC-based open robot control system is investigated. A standard reference model for controlling robots, which consists of a hardware platform, an operating...

Multiplayer computer games play a big role in the ever-growing entertainment industry. Being competitive in this industry means releasing the best possible software, and reliability is a key feature to win the market. Computer games are also actively used to simulate different robotic systems where reliability is even more important, and potentially critical. Traditional software testing approa...

We propose a PC-based real-time software Digital Video Broadcasting-Terrestrial (DVB-T) receiver, including hardware, driver, and software parts. The total data rate of DVB-T is much greater than that of Digital Audio Broadcasting (DAB). A more efficient signal processing algorithm than our previous software DAB receiver is necessary to improve the speed of the software part of the DVB-T receiv...

Microscope has been widely used to observe microscopic objects. The types of microscope are varied according to its function. The conventional optical microscope only provides intensity information of an object and it has some difficulties to provide information about the real shape of the object and the projection of the object in different depth and perspective. In addition, optical microscop...

Beckhoff hit upon the idea of using a PC as a controller in 1986. 25 years ago a floppy disk drive was to be integrated into the controllers with Motorola processors developed up to that point by Beckhoff. Since this task was not quite so easy to accomplish, it was decided to use the PC as the CPU, whereby the floppy disk drive was automatically included. As further developments demonstrated, t...

2 VRMLモデルへの変換 まず、顔ツール群 [2]に含まれる FaceFitを用いて、3次 元ワイヤーフレームモデルを顔画像にフィッティングする。 FaceFitでは、その結果を独自フォーマットで保存してい るが、これに VRML(1.0/2.0)形式でファイルを保存する 機能を追加した。この機能拡張により、作成した顔モデル データを広くインターネットで公開することが可能になる。 また、既存のVRML空間の中にアバタとして顔モデルデー タを自由に組み込むことができる。 一方、顔ツール群に含まれる FaceExpでは、顔モデル データに対する表情付けを行うことができる。VRML2.0 では、モデルの内部状態をフィールドの形で外部に公開し ており、イベントメカニズムを通してこのフィールドの読 み書きを行うことにより、モデルをインタラクティブかつ 動的に変化させることができる [3]。本...

Ansoft Corporation recently acquired Compact Software. This new development offers a win-win relationship among Ansoft, Compact, and — most important — the microwave/wireless circuit design industry. Ansoft wins advanced linear and nonlinear circuit simulation; Compact wins enabling electromagnetic (EM) simulation technology; and the microwave industry wins a clear, viable and comprehensive sol...
