[Title]
Herbal Plants improved Animal Reproduction in Thailand
[Abstract]
Thailand is one of the countries where plant biodiversity is so great. Herbal plants are abundant and are normally used in humans as Thai Traditional Medicine to cure illness or to promote healthy body. Despite its high potential in medicinal properties, herbal plants are not frequently used in animals. Livestock is a type of animal which play crucial roles nowadays as they gives important protein sources for human beings. They are, for example, beef cattle, dairy cows, pigs, buffaloes, sheep, goats and chicken. As world population is increased, the numbers of animals required are also increased to make sure that protein sources are sufficient for human consumption. The number of animals produced are primarily depending on breeding techniques. At present, such breeding technique as Artificial Insemination (AI) with frozen-thawed semen are widely adopted among farmers. Making frozen semen, sperm are processed in a very cold environment starting from room temperature to -196⁰C in liquid nitrogen. During this cold process some free radicals or oxidants are produced and these will cause oxidative stress and damages to sperm cells. To protect sperm from oxidative stress some antioxidants like Glutathione, Catalase, SOD, Vitamin C or vitamin E are added to freezing media before frozen semen is made. A number of herbal plants in Thailand are rich in antioxidants and can be used in animals. In my presentation, some beneficial effects of herbal plants on semen quality will be shown.

Transport Strategic Appraisal: A Comprehensive Decision Making Approach to Collaborate Participatory and Technocratic Processes in Strategic Planning Level for Determining Priority of Mass Transport Development Policy
[Abstract]
Development of mass transportation policy in a metropolitan area has a fairly extensive complexity (multi-aspect and multi-dimensional), hence, it is within the scope of strategic planning. Thus, to assess, evaluate a mass transport policy should also be placed on a strategic level. The problems are, devices and system that can be used for this study is still very limited, especially in countries - developing countries. The number of parties (actors), interest (criteria) and different levels of authority requires a good system, and be able to elaborate on the multi-dimensional condition. This study took Jakarta Metropolitan Area as a study case; a large agglomeration area consisting of the main cities, namely Jakarta with some buffer cities such as Bogor, Tangerang, Depok and Bekasi. In this research, a participatory approach developed by combining Multi Actor Multi Criteria Analysis (MAMCA) which has been well developed with fuzzy approach. While the technocratic approach through the analysis procedure expert judgment using the Modification of Rapid Impact Assessment Matrix and analysis of the characteristics of mass transportation on any policy alternatives. This research successfully developed a transport strategic appraisal decision making system that can used to determining the selection of policy priorities in the development of mass transport in an agglomeration metropolitan area especially in developing country.

Smart street light system based on IoT
[Abstract]
Enormous electric energy is consumed by the street lights, which are automatically turn on when it becomes dark and automatically turn off when it becomes bright. Even if there are no people or cars, the street lights turn on. This is the huge waste of energy in the whole world. This talk gives a smart street light system. The smart street light system turns on lights when there are people or cars and turns off lights when not. Moreover, the smart street light system in this paper behaves like usual street lights that turn on all night. The ideal behavior of the smart street light system is that no one finds turn-off of street lights at night. Realization of the smart street light system uses IoT technology. The system consists of sensors and lights. These elements of systems communicate with each other for smart street light systems.

[Title]
The e-JIKEI Network Camera: Abuse prevention of street camera network by recording browsing-history
[Abstract]
A street camera network, in which many IP cameras are installed at a high density, similar to street lights throughout a nation, will have a stronger positive effect in suspect tracking and crime deterrence in the near future. On the other hand, it will also have a stronger negative effect related to the violation of privacy of ordinary citizens. In order to make such a stronger surveillance camera system, which forcibly captures the images of passersby for the public interest, be accepted as an essential social infrastructure by a society, it is necessary for this camera system to make ordinary citizens be convinced that it is used only for the public interest. To realize this, a new concept, in which the abuse of a street camera network is deterred by recording and disclosing browsing-history, is proposed.

Wearable 2.0 for Sustainable Health Monitoring: Connecting Human with Clouds and Big Data
[Abstract]
With the rapid progress of wireless networking, mobile communications, data mining, and learning techniques, people start to pursue higher quality of experience (QoE). The technology advances should make people healthier and happier. This motivates us to implement a wearable 2.0 healthcare system to improve QoE by integrating wearable computing, big data clouds, robotics and emotion-aware computing technology. In order to enable sustainable health monitoring, we design a novel “smart clothing” system, which gathers ECG signals for emotion detection and other various physiological indicators of human body in a comfortable and durable way. In this talk, an emotion communication system is also introduced, which is a cyber-physical system which can collect emotional data, and transmit them to clouds, and perform emotion analysis by a smart cloud. The vital signs collected by smart clothing are utilized for early disease detection as well. A risk assessment model of chronic disease is introduced using several learning algorithms. The ultimate goal of our system is to provide cognitive intelligence to enhance the quality of life from both physiological and psychological considerations.

Development of a Low Cost Mobile Volcano Early Warning System
[Abstract]
A new early monitoring system has been developed for Indonesian volcano which is in the second place for the most dated eruption after Japan. This low cost system consists of Wireless Sensor Network (WSN) for sensing, processing, distributing and transmitting the data; satellite technology for remote sensing data of the volcano; and mobile robot for replacing a died sensor node in emergency situation. Not only for normal condition when only small events happen, but the system is also robust to a hazard erupting volcano environment to acquire real-time data in high-fidelity operation and manages both the power and bandwidth efficiently in the same time. Simulation and laboratory experimental result show that the system consumed lower energy and utilized better the bandwidth than the current existing system. Furthermore, the mobile robot has been successfully arrived at the desired location for broken node substitution with no human involvement in a toxic dangerous area.

A Proposal of a Numerical Method to Compute Dynamic Responses for Complicated Systems including Elastic/Viscoelastic Structures, Gas, Porous Medea, Nonlinear Restoring Force Element with Nonlinear Hysteresis and Living bodies with Reaction Using Fast FEM
[Abstract]
A new numerical method was proposed to compute dynamic responses for complicated systems involving elastic/viscoelastic structures, gas, porous media and nonlinear restoring force with nonlinear hysteresis and living bodies with reaction using fast FEM.

In this method, there are three features mainly as follows.

(1) By applying asymptotic method to complex eigenvalue problem of the systems, explicit expressions of modal loss factor are derived. This method diminishes computational time for large-scale finite element models. By using this method, modal couplings of damping in the systems can be investigated and optimized. This numerical procedures were proposed by Yamaguchi and were named as Modal Strain and Kinetic Energy Method (MSKE method).

(2) MSKE method is extended for the systems having nonlinear restoring force with linear/nonlinear hysteresis. In this method, the restoring force has nonlinear function as power series of its elongation and nonlinear hysteresis damping using complex coefficients. The discredited equations in physical coordinate are transformed into the nonlinear ordinary coupled equations using normal coordinate corresponding to linear natural modes. This transformation yields computation efficiency. The proposed method is applied to simulation for impact responses of soft structures.

(3) The nonlinear restoring force element with nonlinear hysteresis is extended to apply impact responses of interaction systems between human bodies and machines (e. g. robots and vehicles). Dynamic responses can be computed for alive human bodies in consideration of difference between contraction and relaxing condition of muscle using complex coefficients for the nonlinear restoring force. Further, if negative values are given for the imaginary parts of the nonlinear restoring force element, influences of panic, precaution and foresight on the responses can be investigated.

Application of new water technology to space travel
[Abstract]
Water is a unique chemical substance abundant on the earth.  For example, its true freezing temperature is known to be much below zero degree Celsius, which is widely seen in the atmospheric phenomena.  In human body, 60% is water by weight, but most of chemical reactions for life happens in cellular, aquatic environment.

Combination of gas with water yields strange phenomena.  These days, ‘micro bubble water’ is used for cleaning surfaces in factories.  What if we generate smaller size bubbles?  They tend to stay in the water bottle for more than 6 months. When we choose ozone as gas part, it exibits potent anti-microbial power.

We are exploring applications of nano-bubble water for astronaut drinking water sanitation, etc.  JAXA plans a program to measure microgravity effect in nano-bubble water shelf life.  We may find nano-bubble watger generators on the spacecraft traveling to Mars.

Luminescence from Ln³⁺ Doped in Glass: Properties and Applications

[Abstract]
In recent time, different glass substances are extensively study to enhance their luminescence characteristics, which is used for the development of various luminescence and optical materials in the field of Solid State Lighting. Solid State lighting like W-LEDs, traffic signals, liquid crystal displays, cellular displays etc., are supposed to show an important aspect in the future. These materials save manifold of electrical energy and lower carbon emissions by approximately 28 million metric tons per year, worldwide. Glasses are source of material have properties like low cost, easy to prepare, high transparency at room temperature, hardness along with sufficient strength, excellent electrical resistance, absence of the grain boundaries and continuously variable composition for the optical applications. Glasses doped with Lanthanide ions (Ln³⁺) can be well developed as luminescence materials because of high emission efficiencies, corresponding to 4f–4f and 4f–5d electronic transitions in the Ln³⁺. The 4f–4f transition gives an especially sharp fluorescence patterns from the ultraviolet to the infrared region, because of shielding effects of the outer 5s and 5p orbitals on the 4f electrons. In this review, up and down conversion luminescence properties of the glasses doped with several lanthanide ions, i.e., Ce³⁺, Pr³⁺, Nd³⁺, Sm³⁺, Eu³⁺, Dy³⁺, Er³⁺, Yb³⁺,Tm³⁺, and Tb³⁺ have been explain. Moreover, the current status of their potential applications for solid state lighting materials are also given.

Equivalent-Circuit Modeling of Electrically-Very-Small Wireless Systems

[Abstract]
In recent years, wireless systems much smaller than the wavelength of electromagnetic waves (electrically-very-small) are widely used. Typical examples include near-field communication (NFC) systems, intrabody communication (IBC) systems, wireless power transfer (WPT) systems, and so on and so forth.

Because such systems can be regarded as antenna problems as well as electric circuits, intense researches have been done by engineers in both the fields. However, sometimes their knowledges are separated and hard to integrate because the commonly used design analysis techniques are highly specialized in spite of the fact that they are based on the same physics, i.e. Maxwell’s equations.

In this talk, equivalent-circuit modeling techniques of electrically-very-small wireless systems and their applications are introduced.

X-ray spectroscopic study of liquid water

[Abstract]
Over the past decade, there have been controversies over the interpretation of the local hydrogen bonding structure of water. The beginning of this dispute was the Science paper in 2004, where researchers found an unexpected distortion of hydrogen bonding in liquid water using soft X-ray absorption spectroscopy. Whether the water is homogeneous or inhomogeneous - in terms of this fundamental question, X-ray spectroscopy lead us to a totally different structural model from conventional continuum model of water structure by monitoring the electronic structure of water. In this talk our recent efforts using soft X-ray absorption/emission spectroscopy and discussion about the future of water research are introduced.

Nanopattern Formation of a Block Copolymerby Water as a Non-Solvent

[Abstract]
Block Copolymers (BCPs) have been industrially used as thermoplastic elastomeric materials such as baby diapers, footwear, adhesives, coatings, etc.  BCPs are also used in medical sector, such as medical bags, medical tubing, syringes, and in construction industry, such as paving, roofing, home interiors, etc. In order to improve their functionality, such as applying them to optical devices or hard disc memories, spatial arrangement with the high degree of order is required. Here, we demonstrate how to obtain a highly ordered nanopattern of a BCP in solutions. For visible light, we investigated a pattern formation via microphase separation and order-order transition of a BCP with an ultra-high-molecular-weight (UHMW). Generally, UHMW-BCPs have so high viscosity that they do not reach equilibrated state when they form nanopatterns because of the large number of entanglements per chains. We enhanced the chain mobility by adding to a BCP a neutral solvent, i.e., a miscible solvent to all the components of the BCP (a semi-dilute solution). However, the nanopattern had a low degree of order or disappeared because the segregation power was also extremely shielded due to the dilution effect. Here, we found that addition of a “differentiating non-solvent” (ex. water) in the semi-dilute solution enhances the segregation power and the resulting nanopatterns are highly ordered. The patterns were successfully applied to non-linear optical materials such as photonic crystals..

The FTIR Analysis of   Nd2O3 Substitution on (35-x)CuO-xNd2O3-65P2O5 glasses

[Abstract]
Melt quenching technique (MQT) has been used to prepare the series of (35-x)CuO-xNd2O3- 65P2O5 (0 £ x £ 10 mol%) glasses, The thermal properties and structure of those glasses were investigated. The glass transition temperature increases as the Nd2O3 is substituted for CuO. This behaviour indicates that the replacement of CuO by Nd2O3 improves the strength of the cross-links between the phosphate chains of the glasses. The analysis of the infrared spectra of the studied glasses reveals that the increase of Nd2O3 content decreases the formation of the end groups in phosphate chain structure.

Analog-to-Digital Converter Algorithms for Reliability Based on Number Theory

[Abstract]
This talk describes successive approximation register (SAR) analog-to-digital converter (ADC) algorithms to ensure reliability with possible targets for automotive applications. The SAR ADC has beneficial characteristics of low power and small chip area, and hence it is widely used, especially in automotive applications together with micro-controllers. There, digital error correction method using redundant comparison is an effective method to improve its reliability and conversion speed because it realizes correction of misjudgment at a comparator and incomplete settling of an internal digital-to-analog converter (DAC). Then this talk describes two effective redundancy design algorithms based on number theory: (i) The first one uses Fibonacci sequence and its property called Golden ratio Especially, several interesting properties are clarified that contribute to solve SAR ADC design problems, such as radix standard and shortening required settling time. (ii) The second one uses pseudo silver ratio (square root of 2) for the SAR ADC, which leads to simple SAR logic design and fast conversion speed in case of multiple clock period usage.

 In this presentation, the following statement is emphasized:

“Beautiful mathematics leads to sophisticated electronic circuits.”
