    Deogratias Nurwaha and Xinhou Wang

    This study presents the application of Artificial Intelligence (AI) techniques to predict the morphology of nanofibers
    produced by needless electrospinning method. Two straight and parallel copper wire electrodes electrospinning
    method was used to produce nanofibers. Using digital image processing software Image Journal, Mean Nanofiber
    Diameter (MFD) and Nanofiber Diameter Standard Deviation (NFSD) have been measured and recorded. Adaptive
    Neuro-Fuzzy Inference Systems (ANFIS), Support Vector Machines (SVMs) and Gene Expression Programming
    (GEP) methods were used for prediction of electrospun nanofiber morphology. Prediction results and experimental
    were compared. It was found that SVMs model has better predictive power in comparison with both ANFIS and Gene
    Expression Programming models. However, results provided by both GEP and ANFIS are also acceptable. The
    relative importance of process parameters as contributor to the nanofiber morphology was also investigated. It was
    found that nanofiber morphology was strongly or weakly dependent on processing parameters.

      Influence of Principal Component Analysis as a Data Conditioning Approach for Training Multilayer Feedforward Neural Networks with Exact Form of Levenberg-Marquardt Algorithm

      Najam Ul Qadir*, Md. Rafiul Hassan and Khalid Akhtar

      DOI: 10.37421/2229-8711.2020.11.239

      Artificial Neural Networks (ANNs) have generally been observed to learn with a relatively higher rate of convergence resulting in an improved training performance if the input variables are preprocessed before being used to train the network. The  foremost objectives  of  data  preprocessing  include  size  reduction  of  the  input  space,  smoother  relationship,  data  normalization,  noise  reduction,  and  feature  extraction. The most commonly used technique for input space reduction is Principal Component Analysis (PCA) while two of the most commonly used data normalization approaches include the min-max normalization or rescaling, and the z-score normalization also known as standardization. However, the selection of the most appropriate preprocessing method for a given dataset is not a trivial task especially if the dataset contains an unusually large number of training patterns. This study presents a first attempt of combining PCA with each of the two aforementioned normalization approaches for analyzing the network performance based on the Levenberg-Marquardt (LM) training algorithm utilizing exact formulations of both the gradient vector and the Hessian matrix. The network weights have been initialized using a linear least squares method. The training procedure has been conducted for each of the proposed modifications of the LM algorithm for four different types of datasets and the training performance in terms of the average convergence rate and a proposed performance metric has been compared with the Neural Network Toolbox in MATLAB® (R2017a).

      Sonoluminescence from Ultra-High-Temperature and High-Pressure Cavitation and its Effect on Surface Modification of Cr-Mo Steel

      Toshihiko Yoshimura*, Daisaku Maeda, Takayuki Ogi, Fumihiro Kato and Masataka Ijiri

      DOI: 10.37421/2229-8711.2020.11.240

      Sonoluminescence from various types of cavitation bubbles, namely those of water jet cavitation (WJC), water jet cavitation with a swirl flow nozzle (SFN-WJC), multifunction cavitation (MFC), ultrasonic cavitation (UC), and ultrahigh-temperature and highpressure cavitation (UTPC), wasinvestigated. The sonoluminescence measurements were compared with the surface modification characteristics imparted to Cr-Mo steel. The luminescence intensity of the various types of cavitation was measured using two types of photon counting head, whose detection sensitivity depends on the wavelength range. 2 UTPC had the highest light intensity, followed by MFC, UC, SFN-WJC, and WJC. The temperature inside the bubbles from the various types of cavitation could be estimated using the black-body emission method based on Planck’s law and the emission intensity, which was corrected for the sensitivity of the detector. UTPC, which had high luminosity and could treat surfaces at high temperatures, was found to increase compressive residual stress and decrease surface roughness compared to WJC and SFN-WJC, which had low luminosity and are forms of cold working. At higher cavitation temperature, more corrosion-resistant and oxidation-resistant films form on a steel surface. The magnitude of luminescence intensity for a cavitation process corresponds to the magnitude of corrosion potential (surface potential), which indicates corrosion resistance

      Advances in Centrifugal Compressors

      Natasha Jones*

      DOI: 10.37421/2229-8711.2020.11.243

      In the case where flow passes through a straight pipe to enter a centrifugal compressor the flow is straight, uniform and has no vorticity, ie swirling motion, so the swirl angle α1 = 0° as illustrated. As the flow passes through the centrifugal impeller, the impeller forces the flow to spin faster as it gets further from the rotational axis. According to a form of Euler's fluid dynamics equation, known as the pump and turbine equation, the energy input to the fluid is proportional to the flow's local spinning velocity multiplied by the local impeller tangential velocity. In many cases, the flow leaving the centrifugal impeller is travelling near the speed of sound. It then flows through a stationary compressor causing it to decelerate. The stationary compressor is ducting with increasing flow-area where energy transformation takes place. If the flow has to be turned in a rearward direction to enter the next part of the machine, e.g. another impeller or a combustor, flow losses can be reduced by directing the flow with stationary turning vanes or individual turning pipes (pipe diffusers). As described in Bernoulli's principle, the reduction in velocity causes the pressure to rise.

          Adding Bluetooth Capabilities to the Vehicle Key Fob

          Ziad AlHihi

          While working to deliver an app that send commands to the vehicle, I noticed it will not function properly when the phone battery dies. I thought to have the other regular key as alternative solution but the customers did not like to carry the bulky keys. I did some research and came up with a credit card form factor with the same functionalities of a regular key. I added value of Bluetooth chip that connects to the app. I also realized some customers own multiple vehicles and I added a memory chip to save the key learning of up to four vehicles. From the app we can decide what the active profile is. A system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to transmit a message to the fob indicating a fob action using the mobile device transceiver. The fob is programmed to, using the fob transceiver, receive the message and transmit a second message to a vehicle requesting the vehicle to perform the fob action. In one or more illustrative examples, a system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to transmit a message to the fob indicating a fob action using the mobile device transceiver, and the fob is programmed to, using the fob transceiver, receive the message and transmit a second message to a vehicle requesting the vehicle to perform the fob action. In one or more illustrative examples, a method includes transitioning a fob into valet mode by sending a wireless short-range message to the fob responsive to receiving input to a mobile device to set the fob into valet mode; and transitioning the fob from valet mode into full access mode by sending a second wireless short-range message to the fob responsive to receiving second input to the mobile device to remove the fob from valet mode. In one or more illustrative examples, a system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to, responsive to user input, transmit a message using the mobile device transceiver to the fob to transition the fob from being configured to control a first vehicle profile to being configured to control a second vehicle profile, and the fob is programmed to, using the fob transceiver, receive the message and control the second vehicle.
