Rewriting XQuery to Avoid Redundant Expressions based on Static Emulation of XML Store (2009)
Hiroyuki Kato, Soichiro Hidaka, Zhenjiang Hu, Yasunori Ishihara, Keisuke Nakano
Rewriting composite expressions based on eliminating intermediate results generated by redundant expressions is a traditional optimization technique (known as fusion) in both programming languages...

Bidirectional transformation is a pair of transformations: a view function and a backward transformation. A view function maps one data structure called source onto another called view. The...
Theoretical Analysis of Route Expected Transmission Count in Multi-Hop Wireless Networks (2008)
MIYAKITA, Kazuyuki, NAKANO, Keisuke, SENGOKU, Masakazu, SHINODA, Shoji
In multi-hop wireless networks, communication quality depends on the route from a source to a destination. In this paper, we consider a one-dimensional multi-hop wireless network where nodes are...
Analysis and Relative Evaluation of Connectivity of a Mobile Multi-Hop Network (2008)
NAKANO, Keisuke, MIYAKITA, Kazuyuki, SENGOKU, Masakazu, SHINODA, Shoji
In mobile multi-hop networks, a source node S and a destination node D sometimes encounter a situation where there is no multi-hop path between them when a message M, destined for D, arrives at S. In...
LDTA'01 Preliminary Version Deriving Event-Based Document Transformers (2007)
Keisuke Nakano, Susumu Nishimura
The event-based document transformers, which process a structured document simply as a stream of parsing events, have an advantage over the conventional tree-based ones that they can avoid the...
Bi-X Core: A General-Purpose Bidirectional Transformation Language (2007)
Dongxi Liu, Keisuke Nakano, Yasushi Hayashi, Zhenjiang Hu, Masato Takeichi, Akimasa Morihata, ...
Bi-X Core is a general-purpose bidirectional transformation language, aiming to implement various systems that need synchronization between their input data and output data. In syntax, Bi-X Core is a...

A pushdown machine for recursive XML processing (2006)
Abstract. XML transformations are most naturally defined as recursive functions on trees. Their direct implementation, however, causes inefficient memory usage because the input XML tree is...
KABASAWA, Tatsuya, NAKANO, Keisuke, TANAKA, Yuta, SATO, Ikuo, SENGOKU, Masakazu, SHINODA, Shoji
We investigated performance improvement in a cellular system by introducing direct communication between terminals. Previous research has indicated that direct communication efficiently uses...
Streamlining functional XML processing (2005)
Since an XML document has tree structure, XML transformations are ordinarily defined as recursive functions over the tree. Their direct implementation often causes inefficient memory usage because...

TreeCalc: towards programmable structured documents (2003)
Masato Takeichi, Zhenjiang Hu, Kazuhiko Kakehi, Yasushi Hayashi, Shin-cheng Mu, Keisuke Nakano
A programmable structured document is a structured document with dynamically calculated components that can be specified by users in a functional programming language. TreeCalc, a tree version of...
Deriving event-based document transformers from tree-based specifications (2001)
Keisuke Nakano, Susumu Nishimura
Structured documents are usually processed by tree-based document transformers, which transform the document tree representing the structure of the input document into another tree structure....
Immunohistochemical Characteristics of Bone Forming Cells in Pleomorphic Adenoma
Nakano, Keisuke, Watanabe, Takehiro, Shimizu, Takako, Kawakami, Toshiyuki
Histopathological and immunohistochemical examinations were carried out in a case of pleomorphic adenoma with bone formation, occurring in the chin of a 34-year-old Japanese man. Examination results...
