In this paper, an open architecture control system for automated container cranes is investigated. The hardware architecture for automating cranes is first discussed. A standard reference model for cranes based upon the OSACA platform is proposed, in which three modules are suggested: hardware module, operating system module, and application software module. Finally, a hybrid control system combining deliberative and reactive controls for autonomous operations of the cranes is implemented.

This paper addresses a hybrid control architecture for the hospital service robot, SmartHelper. In hybrid architecture, the deliberation takes place at planning layer while the reaction is dealt through the parallel execution of operations. Hence, the system presents both a hierarchical and an heterarchical decomposition, being able to show a predictable response while keeping rapid reactivity to the dynamic environment. The deliberative controller accomplishes four functions which are path generation, selection of navigation way, command and monitoring. The reactive controller uses fuzzy and potential field method for robot navigation. Through simulation under a virtual environment IGRIP, the effectiveness of the hybrid architecture is verified.

This paper is about a high-speed MAC (multiplier and accumulator) design applying radix-4 and radix-8 Booth's algorithm at the same time. The optimized hybrid radix design for high speed MAC has taken advantage of both a radix-4 and a radix-8 architectures. A radix-4 architecture meets high-speed, but it takes much more power and chip area than a radix-8 architecture. A radix-8 architecture needs less power and chip area than the other, but it has a bottleneck of generating three times the multiplicand problem. An optimized hybrid architecture performs the radix-4 multiplication partially in parallel with the generation of three times the multiplicand for use of the radix-8 multiplication. It reduces the concerned bit width of multiplier in radix-8 multiplication.

The ideas of cyberspace and bio-mechanic hybrid architecture which has been made in conjunction with the electro-mechanic environment and human body as an organic body are newly illuminated in the main stream of contemporary architecture. This study aims at the analysis of the expression of the image of cyborg as a hybrid of an organic body and machine after modern era and its methods of application to arthitectural design. The results are as following: Cyborg is a hybrid of human and machine that is made according to the principle of cybernetics, and is a kind of bachelor machine in the late 20th century. The cyborg images in modern architecture were expressed as prosthetic object-machine, organic image, pataphysical machine. The cyborg images in contemporary architecture are expressed as auto-control function, organic machine, cyberspace.

An optimized hybrid architecture performs tile radix-4 multiplication partially in parallel with the generation of three times the multiplicand for use of tile radix-8 multiplication. It reduces the concerned bit width of multiplier in radix-8 multiplication.

In this study, a cyclic tensile test on a notched butterfly specimen made of woven glass fiber composite was performed on a modified Arcan fixture. During the mechanical test, the sample was monitored with a hybrid stereoscopic system comprised of two visible lights and one infrared camera. The visible light cameras were employed for kinematic measurements using a finite-element-based multiview correlation technique. A semi-hybrid correlation approach was followed, providing Lagrangian temperature fields of the Region of Interest. Due to the complex composite architecture and specimen shape, localized shearing was observed during the tensile loading. Furthermore, asymmetrical damage developed around the notches as revealed by localized strains and thermal hot spots.

Structural behaviors of a sustainable hybrid column with the ultra high performance cementitious composites (UHPCC) permanent form under compression and flexure were studied. Critical state and failure stage characters are analyzed for large and small eccentricity cases. A simplified theoretical model is proposed for engineering designs and unified formulas for loading capacity of the hybrid column under compression and flexure loads are derived, including axial force and moment. Non-linear numerical analysis is carried out to verify the theoretical predictions. The theoretical predictions agree well with the numerical results which are verified by the short hybrid column tests recursively. Compared with the traditional reinforced concrete (RC) column, the loading capacity of the sustainable hybrid column is improved significantly due to UHPCC confinements.

This paper proposes a hybrid-boost Modular Multilevel Converter (MMC) for the Medium-Voltage (MV) Variable Speed Drives (VSDs) employed in subsea applications, such as oil and gas recovery. In the presented architecture, a hybrid-boost MMC with a reduced number of semiconductor devices driving a multiphase Induction Machine (IM) is investigated. The stepped output voltage generated by the MMC reduces or eliminates the filtering requirements. Moreover, the boosting capability of the proposed architecture eliminates the need for bulky low-frequency transformers at the converter output terminals. A detailed illustration of the hybrid-boost MMC operation, the expected limitations/constraints, and the voltage balancing technique are presented. A simulation model of the proposed MV hybrid-boost MMC-based five-phase IM drive has been built to investigate the system performance. Finally, a downscaled prototype has been constructed for experimental verification.

20세기 말부터 시작된 탈근대의 사회와 문화는 새로운 환경설계의 문법을 요구하고 있었고, 당대에 등장한 대지예술은 새로운 혼성적 설계의 계기를 마련해 주었다. 대지예술의 영향아래 건축으로부터 시작된 지형적, 경관적 접근은 환경설계 전반에 장르간 혼성화의 큰 흐름을 일으켰다. 대지예술과 지형건축의 영향을 받은 조경에서는 신픽쳐레스크 조경이 등장하게 되었고, 조경의 영향을 받은 도시설계에서는 랜드스케이프 어버니즘이 태동되었다. 이러한 환경설계 전반에 걸친 땅과 경관에 대한 새로운 관심과 함께 동시대 도시의 유동적 도시활동과 동태성이 중시되면서 시간에 대한 새로운 관심이 일어나게 되었다. 이들 땅과 시간에 대한 새로운 관심들은 혼성적 환경설계장르들의 작업에 필요한 새로운 방법론들을 안출해 내게 하였는데 맵핑과 다이어그램, 폴드가 그것이다. 이들 세 가지 방법론은 특히 랜드스케이프 어버니즘에서 가장 포괄적으로 적용되고 있고, 그 중에서도 폴드는 모든 혼성적 장르에 가장 공통적으로 사용되는 형식으로 나타난다. 다이어그램은 지형건축과 랜드스케이프 어버니즘에 보다 적극적으로 수용되고 있으며, 맵핑은 랜드스케이프 어버니즘에 적극적으로 수용되고 있고, 대지조형적 조경에서는 소극적으로 수용되고 있다. 맵핑이 가지는 진보적 성격에도 불구하고 그 방법론이 개별적이고 주관적이어서 보편적 적용이 어려운 이유로 보인다. 전체적으로 보아 랜드스케이프 어버니즘은 현대도시상황으로 보아 매우 시의적절한 대안적 방법이며, 혼성의 포괄성과 지역성 구현에서 매우 높은 가능성을 보이고 있다. 특히 조경분야가 도시로 영역을 확장할 수 있는 계기가 될 것으로 보여 향후 심도있는 연구가 필요할 것으로 생각된다.
