Keynote Speech’s title:

Microwave Bio-Sensor with High Accuracy of Measurement for Material Properties Detection


The topic of material characterization is one of the most active areas in dielectric properties research today. The microwave sensor development has significant application areas towards characterizing materials such as the chemical industry, food processing, agriculture, pharmaceutical, and bio-sensing. The knowledge of the characterizing materials is important to provide valuable scientific understanding and critical information on electrical characteristic of chemical and bio mechanism to conduct an initial evaluation of the materials. A considerable amount of literature has been published on sensor design such as a coaxial probe, waveguide, and dielectric resonators to extract the dielectric properties of test specimen due to their polar nature and covalent bond. However, these types of sensors are expensive to build, since most of them have a complicated measurement setup and complex design structure. From that particular review, the planar structure of the biochemical resonator sensor is proposed to overcome the drawbacks of existing sensors which is more compact, simple structure design, low manufacturing cost and easy to fabricate. Another concern is most of the planar sensor suffers from poor quality factor and measurement errors which restrict their usage in crucial applications. In this study, however, we present novel structures of planar microwave sensors based on symmetrical split ring resonator (SSRR) and Circular Substrate Integrated Waveguide (CSIW) for determining and detecting the dielectric properties in common solid and liquid materials. The spurline filter is used for producing high Q-factor with capability to suppress the undesired harmonic spurious and undesired frequency. The high sensitivity of sensor with Q-factor of more than 400 and average measurement error less than 0.55% have achieved. This new class of microwave sensor is very important for various industrial applications such as food industry, quality control, bio–sensing medicine and pharmacy.

Keynote Speech Title: Applied Mathematics: From History to Mystery

One could argue that applied mathematics is nearly as old as humanity itself. From the early days when prehistoric men notched Ishangoo bones (20,000 BC) to the creation of Egyptian hieroglyphs to the Hindu-Arabic and Roman numeral systems. Mathematics has developed in parallel in the eastern and western world form simple counting with the Chinese style abacus and the invention of the decimal system to Greek arithmetic of Pythagoras. Practical applications of mathematics included measurements of length, weight and time to calculation of geometric shapes and volumes like the Cavalieri principle to find the volume of a sphere. During the Middle Ages the focus of mathematics was more theoretical as in Euclid’s elements. During the Renaissance mathematics and accounting started to become intertwined, and compound interest calculations spread throughout Europe with the Italian merchant families and the Fuggers of Augsburg. Solid geometry, cubic equations and linear perspective were introduced in 1492 by Piero Della Francesca. In the 17th century Galileo observed the moons of Jupiter and Johannes Kepler calculated planetary motion. Isaac Newton discovered the laws of physics and Gottfried Wilhelm Leibniz developed calculus. Pierre de Fermat and Blaise Pascal discussion of gambling set the groundwork for probability theory and Bernoulli applied mathematics in hydrodynamics and other disciplines. In the 18th century Leonhard Euler founded the study of graph theory and the notations of the Greek letter  for the ratio of a circles circumference to its diameter, and Laplace started statistics to assist Napoleon. In the 19th century Carl Friedrich Gauss did revolutionary work on the functions of complex variables and convergence of series. Bernhard Rieman found that the angels in a triangle add up to 180°. Albert Einstein used differential geometry in his general relativity theory E=m*c2. John von Neumann’s game theory changed the types of questions mathematical methods could answer. All branches of engineering use applied mathematics in various forms, and computer scientist are foremost mathematicians. There are many observable trends in applied mathematics most notable the volume of data that is generated and can be analyzed with the help of computers leads to new algorithms for even more complex systems and discoveries in all major sciences while the academic disciplines are becoming more interdisciplinary and interwoven. Yesterday is history and tomorrow is a mystery that needs to be discovered through more risk taking in research that strives beyond counting indexed peer reviewed journal articles and thinking outside the box.

Keynote Title: Direct Metal Deposition: a breakthrough fabrication process

Rapid Prototyping & Manufacturing (RP&M) has showed significant commercial applications since one technology adapted conventional fusion welding. Considering fusion welding with feed material as an additive manufacturing process, it was seen as a suitable process for the Direct Metal Deposition (DMD) of three-dimensional (3D) structures for repair, feature addition and new component manufacture when equipped with an appropriate manipulation system. Basically, the 3D structure is produced by layer-wise DMD of thin two-dimensional (2D) cross-sections until a final geometry is obtained. In the manufacture and repair of parts by DMD it is common to inject powder into a molten pool formed by laser heating. However, a wire feedstock offers potential advantages over powder due to its lower cost, lower oxide content and higher deposition rate. This talk will describe the heat sources used in various types of DMD process with wire as the additive material, commercial applications, available materials and recent research in this emerging technology. DMD is a breakthrough fabrication process that enables fully dense metal to be manufactured in shorter lead time than conventional shaping processes. Indeed, the future looks bright for DMD.
