In this study, a series of physical and chemical tests were conducted to investigate, evaluate and improve the building cleaning efficiency....

Young children have difficulties to make connections between objects and events around them. They are not able to think systematically and articulate how things are related; lack of reflection makes this worse. We introduced software called Model-It to address the challenges....

Acoustic sensors have been developed for many years. However, most acoustic sensors in application are chemical sensors which rely on the chemical material principle to predict mechanical vibration response signals subject to acoustics waves....

In the past three decades, various optimization based redundancy-resolution schemes have been proposed and developed for the motion planning and control of robot manipulators....

The increasing demand for high bit rate wireless communication prompts people resorting to the mmWave spectrum. A single chip radio becomes possible for the small wavelength of millimeter EM waves. The antenna plays an important role in a radio because its independent properties can affect the radio as a whole....

The field of control theory in PDEs has broadened considerably as more realistic models have been introduced and investigated. This book presents a broad range of recent developments, new discoveries, and mathematical tools in the field....

Die A?konomie des 21. Jahrhunderts ist durch eine immer stA¤rker werdende Fokussierung auf Wissen und Informationen bestimmt a?? man spricht aus diesem Grund auch von einer Wissens- oder Informationsgesellschaft. Dadurch gewinnt der Faktor Mensch als TrA¤ger von Wissen immer mehr an Bedeutung....
