Revealing the Limits of the Source Coding ProblemsNo intellect, no information. The nature of information is digital and discrete. It is invisible, but we can depict it with mathematical science.Each student handles his/her individual research problem.Discussion with the peers is important tosolve it. We must develop partnership and friendship.NishiaraLabCommunication,broadcast,andreadingandwritingonastoragecanberegardedasprocessesofdeliveringinformationfromsourcestodestinations.Inourlab,weformulatethemathematicalmodelsofvariousinformationsystemsandexplorethetheoreticallimitsofthetheirperformance.Forexample,theimplementationofastreamingsystemrequiresaninvestigationoftradeoffbetweenthebandwidthandthecompression.Althoughmanykindsofsuchproductsarealreadyavailableforusage,thetruthbehindthephenomenonisstillnotclear.Atthestartofdigital-broadcasting,emergencysignalsweresenttogetherwithimagedata.However,itturnsoutthatthecompressionprocessofimagedelaysanemergencysignal,andsotheyareprocessedseparatelynow.Byinvestigatingthetradeoffbetweentheprocessingandthedelay,wecanimprovethetransmissionoftheemergencysignals.MikihikoNishiaraAssoc. at the present post since 2007 after a research associate of the university of electro-communications.

By repeating the evolution of the entire population, we can obtain a set of compromised solutions (many options to be chosen) called POS. We hope to apply this technology to numerous applications such as smart grid, cloud computing and derivation of design variables (set of parameters to express complex shapes) in manufacturing.The alumni of our laboratory are working as research and development engineers at the manufacturers in a wide range of areas such as electrical, electricity, communication, information processing, machinery, electric device and medical system. Some of them are faculties at universities including Shinshu University.Professor Kiyoshi TanakaProf. Tanaka has worked at the Faculty of Engineering since 1995. Currently, he is the director of Global Education Center. He has put great effort into industry liaisons with companies and international exchange with universities and research centers abroad. His laboratory has energetically conducted research and education globally by receiving many international students and researchers.The concept of problem-solving using Evolutionary Computation for large scale/many-objective optimization problem; derivation of the set of optimal solutions in the management and the operation of complicated system.Shinshu Univ. has signed the agreement for academic cooperation and exchange with CINVESTAV which is the most prestigious graduate university in Mexico.
