Preface to volumes 8 and 9 of the UEC e-Bulletin
Volumes 8 and 9 of the UEC e-Bulletin are special issues dedicated to highlighting the excellence in research of young
members of faculty on the UEC Tenure Track Program.
Specifically, in 2007 UEC was selected by the Ministry of Education, Culture, Sports, Science and Technology (MEXT)
for its ‘Initiative for the Promotion of Young Scientists' Independent Research’ under MEXT's ‘Special Coordination
Funds for Promoting Science and Technology’.
Following the success of the MEXT program, UEC introduced its own‘Program to Disseminate Tenure Tracking
System’ throughout the university for hiring all members of faculty as assistant professors. To-date, UEC has employed
more than 40 tenure track assistant professors for many hundreds of applicants in this program.
These two issues of UEC e-Bulletin showcase the unique, challenging, and international research being undertaken by
sixteen highly talented tenure track assistant professors at UEC, Tokyo.

Graph-based data mining reveals patterns in learning space use
Collaborative learning spaces where users can study and work together require constant review so that theavailable facilities can be optimised. Present approaches use interviews with users but Kazushi Okamoto at the
University of Electro-Communications (the affiliation when this paper published was Chiba University),
Hitoshi Asanuma, and Kazuhiko Kawamoto at Chiba University propose a mathematical approach to gather
usage information into graphs that can be readily mined to identify usage patterns. They suggest the approach
will be useful for planning interviews and providing evidence to support the responses of interviewees.
The space studied provides movable desks, chairs, and whiteboards, but for ease the researchers defined only
users and moveable desks in the learning space as nodes, where the desks acted as reference nodes. They
defined edges between the nodes where the edge length was determined by the distance between the nodes inreal space. They could then identify groupings defined by nodes and edges from 324 photos taken in the Chiba
University library hourly over the course of two weeks.
The groupings identified were described as subgraphs within graphs that depict usage throughout the space.
Using histograms the researchers could identify the most common groupings or subgraphs, and more
extensive searches of all the data to identify rare groupings. In addition, a mathematical tool for cluster
analysis - "k means ++"- to log the common groupings for different times of the day and week allowed themto see what patterns emerge from the data, such as the common groupings during busy as opposed to quiet
periods in the library.
The researchers conclude that their test of the approach against data for the Chiba University Library"validated that the proposal can provide useful data for interview planning and evidences for interview
results."

Task allocation: Computing the logistics of snow-plowing
In winter, snowfall can rapidly disrupt daily life and impact on Japan's economy. Snowplowing is aconsiderable annual expense, and methods for co-ordinating plowing activity are needed to ensure an efficient,cost-effective service. Clever computer models are needed to manage such complex activities, which involve
many agents and interactions.
Now, Satoshi Takahashi at the University of Electro-Communications, and Tokuro Matsuo at the Advanced
Institute for Industrial Technology in Tokyo have devised a computational method that combines task
allocation and scheduling of individual snow-plows to maximize efficiency1.
The researchers aimed to identify the best routes for multiple snow-plows to take without replicating routepaths, meaning their computer model had to allocate and schedule tasks simultaneously. They consideredvarious routes in the city of Yonezawa as a series of graphical plots; this gave each snow-plow 'agent' a set of
potential arcs, or routes, to follow.
Takahashi and Matsuo then devised an algorithm for task allocation, followed by an agent simulation todetermine the best-fit arcs for each plow at any given time. Their method calculates directed paths thatminimize inefficient movement for each snow-plow, with the option of setting a maximum time limit for atask. Throughout the process, the progress of other snowploughs is monitored so that individual routes can bechanged instantaneously.
The researchers found that a higher number of snow-plows does not equal faster, more efficient clearance.
There are an optimum number of operating snow-plows needed depending on each snowfall scenario. The
model could help direct the country's snow-plow network in future.

Metal mesh filters: Calculating pressure drop
Metal woven meshes are used extensively as filters in multiple industrial settings, including the petrochemicaland pharmaceutical industries. The meshes are carefully designed to allow only particles of a certain size topass through apertures between the warp and weft. Two types of mesh - the plain Dutch weave and twilled
Dutch weave - are particularly desirable because they have high mechanical strength, tiny apertures, and highpressure / heat resistance. However, because of the complexity of the flow paths that fluids take through thesemeshes, overall flow pressure drops as fluid is filtered.
Predicting this pressure drop is important for industry, because of the need to estimate operating power, output
and filter lifespans. Now, Yohei Inoue at the University of Electro-Communications, Tokyo, Japan, together
with scientists across Japan, have used computational fluid dynamics to model how liquids pass through plain
Dutch weave and twilled Dutch weave meshes1. Their insights allowed them to derive an equation to predictpressure drop across the mesh structures.
The team first developed a computational model of the two mesh structures in three dimensions, together withaccurate representation of the resulting aperture sizes in each mesh type. They were then able to clarify theflow patterns through the meshes on a microscopic scale, and visualize patterns of resulting drag forces which
influence flow pressure. The model and subsequent numerical simulations allowed Inoue and his team toderive their pressure drop equations.
The researchers hope their equations will enable the design of a sophisticated Dutch weave filtration process
in future.

Environmentally friendly refrigerant measures up
The fluid flow and heat transfer characteristics of refrigerants in narrow tubes is important for designing heatexchangers for air-conditioning systems. While standard refrigerants have been well investigated,environmental concerns have prompted the development of refrigerants with lower global warming potential,
and the properties of these alternatives have been less well studied so far. A collaboration of researchers inJapan has now reported on the refrigerant R32, which has a low global warming potential.
A previous report had suggested a much better heat transfer coefficient for R32 compared to anotherrefrigerant that had higher global warming potential, that is, R410A. A number of parameters can affect heattransfer coefficients, including the tube diameter, heat flux and vapour quality - the mass fraction in asaturated mixture that is vapour. These affect the type of heat transfer, which include flow boiling, liquid film
evaporation, nucleate boiling and forced convection.
The work was the collaboration of Yudai Matuse at the Hitachi Zosen Corporation, Koji Enoki at the
University of Electro-Communications (the affiliation when this paper published was Tokyo University ofAgriculture and Technology), Hideo Mori and Yoshinori Yamamoto at Kyushi University, and Keishi Kariya
at Saga University. They monitored heat transfer, pressure drop and the phase flow pattern of R32 in a copper
tube with an inside diameter of 1.0 mm. They compared the results with another refrigerant R410A, which had
been extensively reported on previously.
The researchers concluded, "The liquid film evaporation heat transfer was predominant at low quality or low
mass flux in a low heat flux condition." The measured heat transfer data also raised questions with respect topredictions from other studies.

Research on the Earth's upper atmosphere using optical and radio remote sensing
Scientists have been fascinated by the composition of the Earth's atmosphere for centuries. For example, in thelate 1920s researchers first reported that the glow of light in the Earth's atmosphere contained light fromsodium atom. Now, Takuo Tsuda is shooting laser beams into the upper atmosphere and analyzing theresulting scattered light back on earth to study the sodium layer and other layers of the outer atmosphere for
future space utility and for insights into climate change. The research is carried by remote sensing at facilities
in northern Europe, Japan's Showa Station in Antarctica.

Multimodal categorization robots for forming concepts and acquisition of words
Human cognitive functions rely heavily on categorising things and are able recognize them by a minimum of
flexible and predictive cognitive processing, without having to refer to a whole lifetime of experiences. It is
possible to form such categories by classifying perceptive information. Here, Tomoaki Nakamura is studying
the meaning of words by considering a category as a concept and connecting it with words. One of theapplications of this study is to develop intelligent robots that can associate experiences with concepts andwords, with the ultimate goal being to clarify the "human language acquisition process."

Network architectures for ubiquitous networks
Advances in information-communications technology enables users to connect not only computers andsmartphones but other "things" to the internet such as televisions, gas and electricity meters. This new andrapidly expanding field of the "internet of things" (IoT) is a rapidly emerging field of research. Here, Ryo
Yamamoto is devising innovative networking architecture for ubiquitous networks to supersede and overcome
the shortcomings of conventional TCP/IP protocols. Issues to resolve with TCP/IP networks include the factthat an IP address is allocated to each individual device terminal, with associated routing, which is difficult tomonitor and manage in ubiquitous networks.

The University of Electro-Communications (UEC) in Tokyo
is a small, luminous university at the forefront of applied sciences, engineering, and technology
research. Its roots go back to the Technical Institute for Wireless Commutations, which wasestablished in 1918 by the Wireless Association to train so-called wireless engineers in maritime
communications in response to the Titanic disaster in 1912. In 1949, the UEC was established as anational university by the Japanese Ministry of Education, and moved in 1957 from Meguro to its
current Chofu campus Tokyo.
With approximately 4,000 students and 350 faculty, UEC is regarded as a small university, but withparticular expertise in wireless communications, laser science, robotics, informatics, and materialscience, to name just a few areas of research.
The UEC was selected for the Ministry of Education, Culture, Sports, Science and Technology (MEXT)
Program for Promoting the Enhancement of Research Universities as a result of its strengths in threemain areas: optics and photonics research, where we are number one for the number of joint
publications with foreign researchers; wireless communications, which reflects our roots; andmaterials-based research, particularly on fuel cells.
