Leaky coaxial cable which can be used as antennas is able to detect the location of the user in a simple way due to its potential property. In this paper, we proposes a simple method to improve the localization accuracy of 2-D indoor localization using multiple LCX cables. In addition, we also evaluate the channel capacity loss due to the localization error of the LCX-MIMO using our proposed method. en-copyright= kn-copyright= en-aut-name=ZhuJunjie en-aut-sei=Zhu en-aut-mei=Junjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HouPengcheng en-aut-sei=Hou en-aut-mei=Pengcheng kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HouYafei en-aut-sei=Hou en-aut-mei=Yafei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DennoSatoshi en-aut-sei=Denno en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkadaMinoru en-aut-sei=Okada en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Division of Information Science, Nara Institute of Science and Technology kn-affil= en-keyword=Leaky coaxial cable kn-keyword=Leaky coaxial cable en-keyword=Capacity kn-keyword=Capacity en-keyword=MIMO kn-keyword=MIMO END start-ver=1.4 cd-journal=joma no-vol=226 cd-vols= no-issue= article-no= start-page=165 end-page=203 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201706 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Canonical and n-canonical modules of a Noetherian algebra en-subtitle= kn-subtitle= en-abstract= kn-abstract= We define canonical and -canonical modules of a module-finite algebra over a Noether commutative ring and study their basic properties. Using -canonical modules, we generalize a theorem on -syzygy by Araya and Iima which generalize a well-known theorem on syzygies by Evans and Griffith. Among others, we prove a noncommutative version of Aoyamafs theorem which states that a canonical module descends with respect to a flat local homomorphism. en-copyright= kn-copyright= en-aut-name=HashimotoMitsuyasu en-aut-sei=Hashimoto en-aut-mei=Mitsuyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Mathematics, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue= article-no= start-page=90 end-page=95 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=200410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Experience over five years using a shunt placed between the right ventricle and the pulmonary arteries during initial reconstruction of hypoplasia of the left heart en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SanoShunji en-aut-sei=Sano en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshinoKozo en-aut-sei=Ishino en-aut-mei=Kozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawadaMasaaki en-aut-sei=Kawada en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshizumiKo en-aut-sei=Yoshizumi en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakeuchiMamoru en-aut-sei=Takeuchi en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhtsukiShin-ichi en-aut-sei=Ohtsuki en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine and Dentistry affil-num=2 en-affil= kn-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine and Dentistry affil-num=3 en-affil= kn-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine and Dentistry affil-num=4 en-affil= kn-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine and Dentistry affil-num=5 en-affil= kn-affil=Department of Anesthesiology, Okayama University Graduate School of Medicine and Dentistry affil-num=6 en-affil= kn-affil=Department of Pediatrics, Okayama University Graduate School of Medicine and Dentistry en-keyword=Hypoplastic left heart syndrome kn-keyword=Hypoplastic left heart syndrome en-keyword=Norwood kn-keyword=Norwood en-keyword=systemic-to-pulmonary shunt kn-keyword=systemic-to-pulmonary shunt END
