Green algae are of great economic importance. Seaweed is consumed fresh or as seasoning in Japan. The commercial value is determined by quality, color, and flavor and is also strongly influenced by the production area. Our research, based on solid phase microextraction gas chromatography mass spectrometry (SPME-GC-MS), has revealed that volatile compounds(More)
Carotenoids are the precursors of important fragrance compounds in flowers of Osmanthus fragrans Lour. var. aurantiacus, which exhibit the highest diversity of carotenoid-derived volatiles among the flowering plants investigated. A cDNA encoding a carotenoid cleavage enzyme, OfCCD1, was identified from transcripts isolated from flowers of O. fragrans Lour.(More)
We introduce the organization of the Todai Robot Project and discuss its achievements. The Todai Robot Project task focuses on benchmarking NLP systems for problem solving. This task encourages NLP-based systems to solve real high-school examinations. We describe the details of the method to manage question resources and their correct answers, answering(More)
This paper investigates multiple wheeled mobile manipulators coordinating with each other for a common task such as transporting a common object. In our previous work we derived kinematic and dynamic manipulability measures for multiple mobile manipulators transporting a common object and also developed a simulation environment. The main objective of this(More)
The NTCIR-12 QA Lab-2 task aims at the real-world complex Question Answering (QA) technologies using Japanese university entrance exams and their English translation on the subject of " World history ". The exam questions are roughly divided into multiple-choice and free-description styles, and have various question formats, which are essay, fac-toid,(More)
A lightweight, human-in-the-loop evaluation scheme for machine translation (MT) systems is proposed. It extrinsically evaluates MT systems using human subjects' scores on second language ability test problems that are machine-translated to the subjects' native language. A large-scale experiment involving 320 subjects revealed that the context-unawareness of(More)
In the today's information society, where information access is ubiquitous and data is abundantly available, the importance of memorization is giving way to information gathering skills (search, filtering, summarization), and this focus should also be reflected in the educational process. In this study, we focus on the problem-solving skills of information(More)
The raw and boiled odors of celery leaves and stalks were investigated. Among 12 compounds identified as potent odorants, 3-n-butylphthalide 1, sedanenolide 2, and trans- and cis-sedanolides 3, 4 were assessed to be most contributive to the overall odor of celery. These three phthalides, (3E,5Z)-1,3,5-undecatriene, myrcene, and (E)-2-nonenal were common to(More)
Since the very successful release of the world's first mass-produced HEV (hybrid electric vehicle) in 1997, the number of HEVs as well as EVs (electric vehicles) has been gradually increasing in major cities around the world. Reliable and efficient power devices transferring energy between the battery and the motor/generator represent the heart of the(More)
