Professor Haruo Kobayashi and Assistant Professor Anna Kuwana, Division of Electronics and Informatics, Gunma University, Japan, are utilising classical mathematics, including theorems such as number theory and\u0000 control theory in their design of circuits that contain elements of analogue signalling. Analogue circuit planning is regarded as an art as these circuits are typically designed based on mature designers' intuition and experiences in a process that is less systematic for coming up with new\u0000 architectures and more designing than digital circuit design and Kobayashi and Kuwana firmly believe that 'beautiful' mathematics can facilitate truly great circuit design. Additional mathematics techniques employed by Kobayashi and the team are statistics, coding theory, modulation and signal\u0000 processing algorithms and pairing pure mathematics theorems with electrical engineering is a key feature of the researchers' work. The team utilises theoretical analysis and simulations such as the circuit simulator (SPICE) and system simulator (MATLAB) to test its work and collaborates with\u0000 semiconductor companies and electronic measurement instrument companies in Japan for smart circuit design and effective circuit testing. So far, results include that using SAR ADC configurations with Fibonacci sequence weights can improve the speeds and reliability of the SAR ADC. Also several\u0000 new DAC architecutures and waveform sampling methods are derived based on mathematics.","PeriodicalId":88895,"journal":{"name":"IMPACT magazine","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78628172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In his most recent work, Nojima has developed a metallic solution ion source that will be used to construct unknown functional materials by using ion beams made up of specific elements. The metallic solution ion source can generate a copy of an original structure using\u0000 elementally selected materials. With support from the Japan Society for the Promotion of Science (JSPS), KAKENHI, the academic incentive system of the KIOXIA Corporation 2021 and the Toshiba Electric Devices & Storage Corporation 2021, Nojima is seeking to open up new materials for use\u0000 as ion sources utilising electrospray ionisation (ESI) methods. By harnessing the elements of FIBs primarily created from liquid metal ion source (LMIS) by field ionisation processes, Nojima hopes to create new generations of ion beams.

The idea is to mimic things that exist naturally in order to develop artificial things with novel\u0000 properties. Dr Akira Saito, Department of Precision Engineering, Osaka University, Japan, is working to develop new transmissive light materials inspired by butterflies. The blue Morpho butterfly has brilliant blue wings and scientists have discovered that the colour is attributed to a specific\u0000 nanostructure that has both order and disorder. Saito and the team have been working to artificially reproduce this coloration and have proven the optical principles of the Morpho butterfly's reflection, progressed various application technologies and, more recently, found a new direction\u0000 - the transfer from reflection to transmission which has applications in window technologies. The researchers have developed a daylight window that satisfies at once all conditions of high transmittance, wide angular spread, low colour dispersion, and spread-shape controllability and have\u0000 also realised the diffuser that will enable the light source to 'see the object correctly' in terms of the colour rendering. This has potential to be used in fields that rely on different forms of lighting, including fine arts, surgery and various types of photography.
