At the Height of Consciousness: An Analytical Study of Herman Miller

Herman Miller is one of the strongest, most well-known furniture manufacturers in the world today. Since its birth in 1923, the company's innovative management philosophies and programs have delighted employees and clients alike. The purpose of this study is to analyze various aspects of Herman Miller--corporate culture, environment, mission--and explore their implications to further my understanding of the organization and the furniture industry as a whole. The scope of the study is Herman Miller's present situation as analyzed through interviews, periodical research, company literature, and textbooks. A major finding of the study is Herman Miller's unwavering dedication to excellence. I have found the company to be a fine example for other furniture manufacturers, or any other firm, to emulate.B.S. (Bachelor of Science

GigaRad – a multi-purpose high-resolution ground-based radar system

Recently DLR has developed and constructed a new experimental radar instrument for various applications like radar signature collection, SAR/ISAR imaging, motion detection, tracking, etc., where high performance and high flexibility have been the key drivers for system design. Consequently a multi-purpose and multi-channel radar called GigaRad is operated in X band and allows an overall bandwidth of up to 6 GHz, resulting in a theoretical range resolution of up to 2.5 cm. Hence, primary obligation is a detailed analysis of various possible error sources, being of no or less relevance for low-resolution systems. A high degree of digital technology enables advanced signal processing and error correction to be applied. The paper outlines technical main features of the radar, the basic error correction strategy and illustrates some first imaging results

Strain-rate Dependence for Ni/Al Hybrid Foams

Shock absorption often needs stiff but lightweight materials that exhibit a large kinetic energy absorption capability. Open-cell metal foams are artificial structures, which due to their plateau stress, including a strong hysteresis, can in principle absorb large amounts of energy. However, their plateau stress is too low for many applications. In this study we use highly novel and promising Ni/Al hybrid foams which consist of standard, open-cell aluminium foams, where nanocrystalline nickel is deposited by electrodeposition as coating on the strut surface. The mechanical behaviour of cellular materials, also under higher strain-rates, is governed by their micro-structure due to the properties of the strut material, pore/strut geometry and mass distribution over the struts. Micro inertia effects are strongly related to the micro structure. For a conclusive model the exact real micro-structure is needed. In this study a micro-focus computer tomography (μCT) system has been used for the analysis of the micro-structure of the foam samples and for the development of a micro-structural Finite Element (micro-FE) mesh. The micro-structural FE models have been used to model the mechanical behaviour of the Ni/Al hybrid foams under dynamic loading conditions. The simulations are validated by quasi-static compression tests and dynamic split Hopkinson pressure bar tests.JRC.G.4-European laboratory for structural assessmen

Broadband Polarizer Miter Bend for High Power Radar Applications

Polarizer miter bends are used to alter the polarization in overmoded waveguides. For future space debris observation with broadband high power W-band radar sensors these are important transmission line components. A polarizer miter bend uses a grooved mirror as phase grid for polarization. The present paper addresses a suitable design of such a phase grid for broadband high power radar applications within the frequency range from 90GHz to 100GHz. An appropriate parameter combination is found by a parametric study. For reduction of the required amount of calculation a plane wave approximation and unit cell simulations are used. With a suitable parameter combination a cross polarization of Xpol B −26 dB can be achieved within the considered frequency range. This corresponds to a suitable value for radar applications
