Title: Fatigue crack initiation at a notch

Plenary Talk

Prof. N.Ranganathan

University of Tours, France

Abstract

A short crack approach has been developed to determine the fatigue crack initiation life at a notch tip, in which the initiation life is assumed to correspond to the period during which an initial crack, equivalent to a microscopic defect, grows to attain a detectable size. This approach is compared to conventional local strain approach and it is shown that the short crack approach gives acceptable predictions as compared to experiments, in the 2024 T351 alloy. In the 7449 alloy, a different approach, using marker band technique has been applied to determine the short crack growth kinetics at a notch. The advantages and disadvantages of the conventional strain based approach and the short crack model are discussed.

Title: Stereolithographic Additive Manufacturing of Ceramic Components with Functionally Modulated Dimensions

Keynote

Prof. Soshu Kirihara

Osaka University, Japan

Abstract

In stereolithographic additive manufacturing (STL-AM), 2D cross sections were created through photo polymerization by UV laser drawing on spread resin paste including nanoparticles, and 3-D models were sterically printed by layer lamination. The lithography system has been developed to obtain bulky ceramic components with functional geometries. An automatic collimeter was newly equipped with the laser scanner to adjust beam diameter. Fine or coarse beams could realize high resolution or wide area drawings, respectively. As the row material of the 3D printing, nanometer sized metal and ceramic particles were dispersed into acrylic liquid resins at about 60 % in volume fraction. These materials were mixed and deformed to obtained thixotropic slurry. The resin paste was spread on a glass substrate at 50 μm in layer thickness by a mechanically moved knife edge. An ultraviolet laser beam of 355 nm in wavelength was adjusted at 50 μm in variable diameter and scanned on the spread resin surface. Irradiation power was changed automatically for enough solidification depth for layer bonding. The composite precursors including nanoparticles were dewaxed and sintered in the air atmosphere. In recent investigations, ultraviolet laser lithographic additive manufacturing (UVL-AM) was newly developed as a direct forming process of fine metal or ceramic components. As an additive manufacturing technique, 2D cross sections were created through dewaxing and sintering by UV laser drawing, and 3D components were sterically printed by layer laminations with interlayer joining. Though the computer aided smart manufacturing, design and evaluation (Smart MADE), practical materials components were fabricated to modulate energy and material transfers in potential fields between human societies and natural environments as active contributions to Sustainable Development to Goals (SDGs).

Title: Blocking ion migration to improve the stability of unencapsulated perovskite solar cell

Keynote Talk

Dr. Yang Li

University of Macau, China

Abstract

Perovskite solar cells (PSCs) witnessed an impressive development towards commercialization in the past few years. However, the ion migration inside PSCs hinders further enhancement on their long-term stability and influences the device performance. Among all fabrication technologies for n-i-p PSCs, ions blocking layer (IBL) plays an important role in enhancement of device stability. Herein, we have developed two kinds of spiro-structured small molecules, named S1 and S2, as IBLs in n-i-p PSCs. The device based on S2 exhibits excellent long-term stability, which remains 95% of its initial efficiency after storage in ambient (around 40% humidity) for more than 3000 h. Our methodology paves out a path for fabricating more efficient and stable PSCs. Besides, due to the improved crystallinity of perovskite film and enlarged charge carrier length enlarged caused by surface passivation effect, the device based on S2 exhibits steady power conversion efficiency (PCE) above 21% at maximum power point (MPP), surpassing the pristine one without IBL (18.5%).

Title: Session Title: Enabling Operationalization of MLOps Automation at Scale

Invited Speaker Talk

VirooPax Mirji

WinWire Technologies, United States

Abstract

Several organizations do not consider the implications of deploying models in production with scalability & high data quality in mind. They remain confined to sandboxes or work within silos in an organization with no defined process for automating/managing the MLOps lifecycle. The total value of upcoming AI applications in healthcare, life sciences, and pharma is enormous. But how can any company build, deploy, and maintain 10,000 custom models without hiring 10,000 machine learning engineers? Why do many proof-of-concept implementations and demos do not make it into production? While a team of engineers can build a one-off application, we still need better tools and automation to make this work scalable and economically viable. Also, if we want to relieve data scientists and engineers from such repetitive and tedious tasks, we should consider a better MLOps approach to scale the commercialization of AI projects.

Title: TUNABLE Q-SWITCHED ERBIUM-DOPED FIBER LASER WITH METAL BASED SATURABLE ABSORBER IN CONJUNCTION WITH INTERFERENCE FILTER

Keynote Talk

Dr. Zairi Ismael Rizman

Universiti Teknologi MARA Shah Alam, Malaysia

Abstract

Cost-efficient, robust, and tunable laser systems are vital for a wide range of applications ranging from optical communication to sensing. This research aims to explore metal oxide nanoparticles and pristine (pure, original) metal nanoparticles as Q-switcher SA in tunable Erbium-doped fiber laser (EDFL) cavities. The generations of Q-switched pulses with a tunable output wavelength in 1.55 µm regions have been successfully demonstrated using a nickel oxide (NiO), vanadium pentoxide (V2O5), gold, silver, or titanium nanoparticles as SA. Sagnac loop mirror (SLM) and Fabry-Perot (FP) tunable bandpass filter (TBF) methods were employed for tuning the operating wavelength of the Q-switched lasers. For instance, a tunable Q-switched EDFL was successfully realized using a NiO SA in combination with TBF with 1 nm bandwidth. The wideband operation of NiO enables broadband tunability from 1535 to 1565 nm. At an operating wavelength of 1535 nm, the repetition rate increases while the pulse width reduces with increasing output power. The highest slope efficiency was 22.11% at the operating wavelength of 1540 nm. At 1565 nm wavelength, the highest pulse energy was obtained at a pump power of 37.7 mW. It is found that the TBF provides a wider tuning range with more efficient Q-switching compared to SLM tuning, which induced a higher cavity loss. These findings show that the metal oxide and pure metal nanoparticles based SAs have great potential for photonic applications. Such wideband tunable Q-switched laser could provide a simple and low-cost light source for various applications including sensing, metrology, and biomedical diagnostics.

Title: Computation of Combined Electrical and Magnetic Field Effects on Dissipative Immiscible Newtonian Fluid/Nanofluid Dynamics

keynote Talk

Prof. J.C. Umavathi

Gulbarga University, India

Abstract

This article presents numerical simulations for nonlinear mixed convection heat transfer in an enclosure divided into two immiscible regions comprising a non-conducting Newtonian viscous fluid and an electromagnetic viscous nanofluid.  The enclosure walls i.e. parallel vertical plates are sustained at constant asymmetric temperatures and the top and base walls are shielded.  An interfacial stress condition is employed at the junction between the two immiscible fluid zones. The Tiwari-Das nanoparticle fraction model is deployed. The coupled transport equations for both a Newtonian fluid and a Newtonian electromagnetic nanofluid are formulated, rendered dimensionless and then solved numerically with finite difference method adopting the efficient Southwell Over-Relaxation (SOR) method subject to appropriate boundary conditions. The influence of pertinent parameters including the Grashof (thermal buoyancy) number, Brinkman (viscous dissipation) number, Hartmann (magnetic) number, electric field load parameter, nanoparticle solid volume fraction in addition to different nanoparticles (metallic and carbon-based) and base fluid material properties on the thermo-convection flow characteristics are discussed. The results indicate that flow rate is boosted with increasing convective and viscous dissipations, and electric field load parameter and it is depleted with greater Hartmann number and solid volume fraction reduce the flow rate. Significant elevation in both velocity and energy is produced with increasing electric load parameter (both short and open circuit cases). An increment in Grashof number decelerates the flow adjacent to the left plate and accelerates the flow at the opposite wall. The combined action of electrical and magnetic field exerts a more dramatic influence on transport characteristics compared with thermal buoyancy (Grashof number). By adding different nanoparticles (e.g. aluminium oxide, copper oxide and graphite oxide) and using alternative base fluids (blood, water and engine oil), more noticeable modifications in heat and momentum characteristics are achieved with copper oxide nanoparticles. The study finds applications in nano-doped electromagnetic hybrid fuel cells, medical flow processing (electromagnetic blood flow meters), sensing systems in chemical engineering etc.

Title: Prospective and Challenges of micro-plasma technology

Invited Speaker Talk

Dr. Rajneesh Kumar

Banaras Hindu University, Varanasi, India

Abstract

Contracted plasma sources or micro to nano plasmas have found a number of significant applications. Microplasmas can be defined as plasmas where at least one plasma dimension is in the sub-millimeter range. During the last decade a number of microcavity plasma devices have been developed. Examples are microhollow cathode (MHC) discharges and cathode boundary layer (CBL) discharges. The advantage of this technology is that large numbers of miniature atmospheric-pressure non-equilibrium discharges can be operated in parallel. Applications include emitters for visible and UV radiation, photodetectors, sensors, decontamination, surface modification, etching, film deposition, generation of nanoparticles. Novel applications are expected from the combination of microreactor technology with non-equilibrium plasma chemistry. Further it is interesting to mention that the implementation of semiconductor and microelectronics and MEMs microfabrication techniques has resulted in the realization of microplasma arrays as large as 250,000 devices. Fabricated in silicon or ceramics with characteristic device dimensions as small as 10 µm and at packing densities up to 104 cm−2, these arrays offer optical and electrical characteristics well suited for applications in medical diagnostics, displays and environmental sensing. Several microplasma device structures, including their fundamental properties. Moreover, microdischarge has also been used to form plasma column in the plasma photonic crystal for study the positive and negative refraction of x-band microwave. For this purpose, three electrodes are made by molybdenum foil and alumina used as a dielectric to make sandwich of electrodes with the hole of diameter 0.5 to 1 mm. High temperature glue is used to pack the electrodes and alumina. Two DC power supplies are used to produce voltage differences between electrodes. Typical cathode voltage is 800 V and anode voltage varies from 1 to 2 kV maintaining current up to 15 mA. Argon and helium gases are used as background gases in the glass chamber. Experimental results will also be discussed in present talk.

Title: Numerical Analysis of Through-plane Separator Shape on Temperature Distribution in Single Cell of PEFC Operated at Higher Temperature than Usual

Keynote Talk

Dr. Akira Nishimura

Mie University, Japan

Abstract

According to NEDO road map 2017 of Japan, polymer electrolyte fuel cell (PEFC) system is required to be operated at 363 K and 373 K for stationary and mobility applications, respectively. I already reportetd that the combination of thin polymer electrolyte membrane (PEM) and thin gas diffusion layer (GDL) is effective to obtain high power generation performance at higher tempreature. In this study, the impact of separator thickness on distribution on reaction tempearature (Treact) changing relative humidity (RH) of supply gas and initial operation temperature (Tini) with using thin PEM and thin GDL. As a result, wider tempreature distribution is confimed in the case of thickness of 2.00 mm while the tempreature increases along with the gas flow through the gas channel by approximately 2 K in the case of thikcness of 1.50 mm and 1.00 mm. In the case of thickness of 1.50 mm amd 1.00 mm, the impact of RH on distributions of Treact – Tini is larger with increase in Tini. The tempearture difference between the maximum and minimum temperature decreases with increase in Tini irrespective of RH as well as separator thickness excluding the case of anode of 80 %RH and cathode of 80 %RH using separator thickness of 2.00 mm. It is revealed that the wider temeprature ditsribution causes the decrease in power genreation performance. This study can propose the thin separators such as thickness of 1.50 mm and 1.00 mm are not suitable for higher opreation than usual.

Title: Specialty Optical Ring Fibers Supporting OAM Modes for Future Optical Communication System

Plenary Talk

Prof. Yang Yue

Xi'an Jiaotong University, China

Abstract

Orbital angular momentum (OAM) multiplexing technology is expected as one of the prospective candidates for sustaining the further increment of data-transmission capacity in the optical communication systems. An OAM-carrying beam has a doughnut shaped intensity profile due to its twisted helical phase front. Besides, the amount of 2π phase shift that occurs in the azimuthal direction represent different states or modes, which are orthogonal to each other while propagating coaxially. These properties enabled researchers to push the frontiers of OAM in optical communication systems. The complex multiplexing formats of combining mode division multiplexing (MDM) technology based on OAM modes with dense space-division multiplexing (DSDM) along multicore/multimode fibers can be utilized to further improve the transmission rate and spectrum efficiency.

In this talk, we will review our recent work on new type fibers support numerous OAM modes. Firstly, we design an air-core fiber with a single As2S3 high-index thin ring, which can support 1322 OAM modes at 1550 nm while maintaining single radial mode condition. Based on this fiber material, we further introduce the concept of multi-ring fiber and propose a multi-ring air-core chalcogenide fiber, which has 37 rings and can support a record high 4440 radially fundamental OAM modes at 1550 nm, featuring low inter-ring crosstalk and large intra-ring modal effective refractive index difference. The chalcogenide material is promising but it could lead to the relatively low mode purity. It might be more suitable to be utilized in short-distance applications such as short-reach optical interconnect in data centers and high-performance computers. In this case, we propose a 7-ring-core Ge-doped fiber and it can provide 434 OAM modes across C and L bands. The 7-ring-core Ge-doped fiber has relatively high mode purity and has great potential to increase the spectral efficiency and the overall capacity in long-distance fiber-based communications system.

According to the European Union Space Policy, the GNSS (Global Navigation Satellites Systems) programs play an important role, and the estimated budget for the space programme, according to the current status of the multiannual financial framework for 2021-2027, is around 14 billion euros in current prices. The cybersecurity audits are considered critical within these programs. The cybersecurity audits are described as the evaluation of the level of compliance of the information security management system and implemented security measures with defined requirements, security policies in place and the appropriate safety standards. The conference will highlight the importance of the logistics when performing the planning phase of these cybersecurity audits, and the most relevant lessons learnt at the European Space Agency about this topic. The number of interfaces and interdependencies in these systems, the increasing trend in subcontracting parts of the systems, the technical and legal requirements and the high number of facilities involved make the process really complex. In this conference, the author will introduce the concept of cybersecurity audits, explain some of the factors that contribute to the complexity of the projects in the space sector along the supply chain, and describe how the logistic is impacting the audit process to conclude with some recommendations to be taken into account to facilitate the process.

Title: Dynamic Responses Measured by Fiber Bragg Grating Sensors

Speaker

Prof. Shiuh-Chuan Her

Abstract

Basing on the shift of Bragg wavelength, fiber Bragg grating sensors (FBG) have been employed to measure a variety of physical parameters such as stress, strain, displacement, temperature, vibration and pressure. FBG with small size, light weight, immunity to electromagnetic interference (EMI) and corrosion and embedding capability has demonstrated its inherent advantages for integration in civil structures. In this work, the FBG was connected to an optical spectrum analyzer (OSA) to measure the mechanical strain. The measuring results were validated by a strain gauge with an error less than 5 %. In order to measure the dynamic responses, the FBG was incorporated with an optical filter and photo detector to convert the shift of Bragg wavelength to a change of light intensity. The experimental tests of dynamic three-point bending test and free vibration test of a cantilever beam were presented to demonstrate the capability of measuring dynamic responses using FBG sensors.

Title: Identification of Solids for True Design and Detailed Characterization of Functional Materials

Plenary Talk

Abstract

 

How can we design functional solid materials, such as catalysts and photocatalysts? What is the decisive structural parameters controlling their activities, performance or properties? What is obtained as structural properties by popular conventional analytical methods, such as X-ray diffraction (XRD) or nitrogen-adsorption measurement, is limited to bulk crystalline structure and specific surface area, i.e., no structural characterization on amorphous phases, if present, and surface structure has been made so far. This is because there have been no macroscopic analytical methods to give surface structural information including possibly-present amorphous phases. Recently, we have developed reversed double-beam photoacoustic spectroscopy (RDB-PAS) which enables measure energy-resolved distribution of electron traps (ERDT) for semiconducting materials such as metal oxides [1,2]. Those detected electron traps (ETs) seem to be predominantly located on the surface for almost all the metal oxide particles, and therefore they reflect macroscopic surface structure, including amorphous phases, in ERDT patterns. Using an ERDT pattern with the data of CB bottom position (CBB), i.e., an ERDT/CBB pattern, it has been shown that metal oxide powders, and the other semiconducting materials such as carbon nitride, can be identified without using the other analytical data such as XRD patterns or specific surface area, and similarity/differentness of a pair of metal-oxide samples can be quantitatively evaluated as degree of coincidence of ERDT/CBB patterns. In this talk, an approach of material design based on the ERDT/CBB-pattern analyses is introduced [3,4].
