    Breast carcinoma has become one of the most frequently diagnosed life threatening cancer among women. Early detection of breast cancer is highly essential with the aid of non-contact imaging modalities. Recently, non-contact breast imaging methods based on fringe projection has been developed for breast surface change inspection. In this work, a non-contact digital fringe projection imaging modality that utilizes phase shifting fringe patterns for identifying surface changes has been developed for investigating breast surface changes caused by the presence of tumors. A medical grade prosthetic breast was used as the experimental subject and subjugated to breast changes through the enlargement of a round shaped silicon catheter as a tumor. The fringes were projected onto the breast surface based on the three steps phase shift fringe projection. The fringe patterns consisted of a large fringe width to enable the breast image to be confined in fewer fringe patterns. A resulting phase map was obtained where pixel coordinate marking was conducted on the phase map breast image. Each of the pixel’s coordinate was compared to identify the location of the surface changes. A range of 2-9 pixel coordinate shifts from the 0.5 – 2 cm tumor growth were obtained from the results which demonstrated the capability of using phase map analysis from digital fringe projection in identifying surface changes of the women’s breast.

    In this work, we investigate the impact of employing silicon-on-nothing (SON) versus silicon-on-insulator (SOI) on the electrostatic performance of a transistor with various ground-plane (GP) structures of Lg = 10 nm through the use of Sentaurus TCAD simulator. The digital figure-of-merit (FoM) of interest includes the results of drain-induced barrier lowering (DIBL) which is a major indicator of a control of short-channel effects (SCEs). It is found that SOI devices produce a lower off-current (Ioff) as compared to SON. In terms of the different GP architectures, the introductions of various GP architectures were found to affect the values of DIBL in SOI whereas the impact on SON is negligible. It can be concluded that GP-B architectures with ground plane underneath the channel areas of SOI is most effective in suppressing substrate depletion effects as evidenced from the lowest DIBL produces.

    The performance of film bulk acoustic wave resonators (FBAR) is greatly dependent on the choice of piezoelectric materials. Different piezoelectric materials have distinct properties that can impact the performance of FBAR. Hence, this work presents the analysis of three different piezoelectric materials which are aluminum nitride (AlN), scandium aluminum nitride (ScAlN) and zinc oxide (ZnO) on the performance of FBARs working at resonance frequencies of 6 GHz until 10 GHz. The one-dimensional (1-D) modelling is implemented to characterize the effects of these materials on the quality (Q) factor, electromechanical coupling coefficient (k2eff) and bandwidth (BW). It is determined that employing ScAlN in FBAR results in the highest Q factor, ranges from 628 to 1047 while maintaining a relatively compact area (25 μm × 25 μm) and thickness (430 nm to 720 nm). However, ScAlN yields the narrowest BW, measuring 0.11 GHz at 6 GHz, as opposed to AlN and ZnO, which exhibit broader bandwidths of 0.16 GHz and 0.23 GHz, respectively.

    This paper discusses the effects of pH and concentration on the capability of E. coli ATCC29522 and S. epidermidis RP62A biofilm with bentonite in removing divalent copper, nickel and lead from wastewater. Batch adsorption study at laboratory scale was utilized to evaluate the potential use of bacterial biomass (E. coli ATCC29522 and S. epidermidis RP62A) aided with geosynthetic clay (bentonite) for the removal of Cu2+, Ni2+and Pb2+. Results revealed that removal of Cu2+, Ni2+and Pb2+ by both types of organisms supported with bentonite were high in the first 4 hours of the experiment. This illustrates that the binding site on that particular time was abundant. Hence, the removal rate was evident at high concentration depicting the line adsorption equilibrium. It also revealed that S. epidermidis RP62A supported with bentonite had the highest affinity to Copper and Lead with Qm = 277.7 mg/g and 5.0075 mg/g, respectively. While E. coli ATCC 29522 had the highest affinity to Nickel (Qm= 58.82 mg/g). Hence, the sorption of Cu2+, Ni2+and Pb2+ onto E. coli ATCC29522 and S. epidermidis RP62A biofilm supported with bentonite clay occurred through monolayer chemisorption on the homogeneous surface of E. coli ATCC29522 and S. epidermidis RP62A biofilm with bentonite clay. Batch kinetics studies revealed that the sorption of Cu2+, Ni2+and Pb2+ onto E. coli ATCC29522 and S. epidermidis RP62A biofilm supported with bentonite clay was well described by a pseudo-second-order equation model of type 1 (R2 = 0.9999), which implies that chemisorption is the rate limiting step.

    Recent advancement of vehicle technologies has resulted in development of replacing conventional Internal combustion engine (ICE) to Electric Vehicle (EV) mostly powered by Lithium-ion batteries (LIB). These batteries contain massive amount of energy confined in a very small space. Thermal runaway occurs when the batteries and its circuits start to heat up anomaly. Thermal runaway can cause failures that can lead to battery ignition, resulting in explosions and imminent threats to life and property. This research focused on MEMS capacitance pressure sensor, using three distinct square slotted diaphragm designs: clamped-square, four-slotted-square, and eight-slotted-square diaphragms. The investigation commenced with an evaluation of diaphragm performance, and subsequently, the diaphragm was integrated into the structure of the MEMS capacitive pressure sensor and subjected to simulation. Varied pressure levels ranging from 0.1 to 0.35 MPa were applied to both the diaphragm and the pressure sensor. The outcomes revealed that the eight-slotted-square diaphragm yielded the most substantial displacement, registering at 5.507 μm. It also exhibited the highest Mises stress of 644.67 MPa, and recorded the highest mechanical sensitivity at 15.7545 (10-12/Pa). The clamped-square design, despite its slotted area, yielded the highest capacitance value among the three designs for the pressure sensor.

    The digital fringe projection has been widely used in the field of surface imaging however its application in the field of body imaging especially for human breasts is still quite limited. Currently, the common imaging modality for breast tumor diagnoses are breast ultrasound and mammogram. There are advantages and limitations of using the mammogram and ultrasound in terms of the procedure of the process and the non-invasive nature of the procedure. In this work, an automated digital fringe projection system is developed to execute the imaging of surface changes of a helical shaped phantom breast. The fringe projection setup utilizes a computer, LCD projector, and a CCD camera. The tumor used was round-shaped with a diameter size of 1.5 and 2 cm. The fringe pattern was projected through the three-step phase shift where a resulting phase map was obtained. Results demonstrated that the system was able to identify an average pixel shift of five and ten on the breast surface caused by the presence of the round breast tumors.

    Flip chip (FC) has been used to replace wire bond due to its better performance. The 1st interconnection in FC plays an important role in terms of reliability study. Au/Cu stud bump capped with Sn tends to have Kirkendall void in the joint which can cause open circuit. This paper focuses on depth analysis on solderless chip bumping by using only Cu stud bump in the chip on chip (CoC) ball grid array (BGA) package. High temperature storage 150 °C has been applied on package and the result was compared with those the use of Au stud bump capped with Sn. The result shows that Cu stud bump has a better reliability in term of electrical resistance compared with Au stud bump capped with Sn. Therefore, solderless chip bumping has the potential to replace Au stud bump capped with Sn for FC BGA package.

    The application of ultrasonic transducers is relying on the frequency which the transducers resonated. In the imaging application, an ultrasonic transducer should possess resonant frequency that higher than 2 MHz while in ultrasound testing, a range of 2 to 10 MHz is seeming to be adequate. This report is investigating the performance of high frequency Si-based PMUT with different piezoelectric material used in the structure. The piezoelectric materials used are Aluminium Nitride (AlN), Lead Zirconate Titanate (PZT), and Zinc Oxide (ZnO). Using the same dimensions, the obtained resonant frequencies of PMUT are 4.0370 MHz, 2.8224 MHz, and 3.4358 MHz for AlN, PZT and ZnO respectively.
