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

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.

In this paper an improvement of a well-known nature inspired meta-heuristic algorithm is compared with the original algorithm i.e. Multi-Verse Optimizer (MVO). Multi-Verse Optimizer with Time Freeze Effect (MVOTFE) is compared with original MVO in terms of optimization performance, time taken and convergence behavior. MVOTFE is first tested with same 19 benchmark test problems that are used by MVO. MVOTFE uses same mathematical model as used by MVO with only addition of time freeze effect in the algorithm. Comparative analysis suggests that MVOTFE not only outperforms original MVO in 16 out of 19 test problems but also provides faster convergence in lesser time. As indicated by convergence curves, it also effectively escapes from local optima present in the search space.

The purpose of this paper was to investigate the preferred contexts in learning number concepts in integers. The research also looked at the impact of contexts in the interpretation of the integer using stories. The researcher decided to interrogate and find out if the use of contexts could enhance the learners’ academic performances. The problem is the intermediate phase learners are operating two grade levels behind the expected and South African intermediate phase learners are performing poorly in Mathematics. The scope is on focus relevance, appropriateness, and correctness in the development of mathematical thinking and practice. The argument is the use of contexts in learning number concepts can facilitate the understanding of the learning of the number concept integers. Discussions on different contexts for learning integers were done by intermediate phase learners (Grade 4-6) in one primary school in Johannesburg North in Gauteng Province. Interviews on preferred contexts in learning number concept integers comprised 29 learners. The research adopted a qualitative approach of analyzing the interview responses from the learners. Analysis of results indicates that the use of preferred contexts in learning number concepts in contexts can either facilitate or hinder the learning of number concepts in integers in the intermediate phase. The findings imply that the use of contexts has a positive or a negative impact on the learning of number concepts in context integers. These results can be generalized to all the other learners who are in the same phase.

In this paper, the performance of a multi- swarm Harris Hawk’s Optimization algorithm is reported on a set of benchmark functions provided by CEC2005. In literature, any multi-swarming technique has not been applied to Harris Hawk’s Optimization. In this algorithm, the population is designed to include a number of swarms. All the swarms follow the original algorithm of HHO; however, agents from different swarms are regrouped frequently. Regrouping is performed using random permutation and the global best among all the swarms is considered as Rabbit or Best Solution so far, after iteration. Results show significant improvements in benchmark functions
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).
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.
