Smartphone is on everyoneโs hand and Vietnamese spend hours playing with it. We made the research as to what apps are indispensable for those who live in urban area of Vietnam.
After a period of strong loan book growth during 2013-2017, Vietnam has witnessed a slowdown - the national loan book grew by 14% in 2018 compared to 18% in 2017. Concerns about aggressive lending practices, and the possible risk in the real estate and non-production sectors have resulted in a tightening of regulations by the State Bank of Vietnam (SBV). Additionally, the focus was on resolving the legacy bad debt with the resulting non-performing loans ratio (NPL) at only 1.89% by YE2018. Considering these events, the SBV also set a modest target of 14% YoY credit growth for 2019.
The strongest driver for credit growth, the consumer finance market, has been maturing after several years of exponential growth. In 2018, CF increased its contribution to the national loan book, at 19.7%, compared to 16.7% in 2017. At the same time, although the market has been growing at 59% YoY for the last five years, in 2018, the overall growth registered at 30.4%. The slowdown is attributed to the marketโs development, growing from a larger base, the increasing exposure to real estate loans, as well as the saturation of some of CF key products such as installment loans for home appliances and consumer electronics.

The sensor data may be remotely recorded, such as video, radar, or other wireless methods. It contains data generated from accelerometer, gyroscope and other sensors of Smart phone to train supervised predictive models using machine learning techniques like SVM , Random forest and decision tree to generate a model. Which can be used to predict the kind of movement being carried out by the person, which is divided into six categories walking, walking upstairs, walking down-stairs, sitting, standing and laying?
MLM and SVM achieved accuracy of more than 99.2% in the original data set and 98.1% using new feature selection method. Results show that the proposed feature selection approach is a promising alternative to activity recognition on smart phones.
Leveraging the Power of Smartphones: Real Time Monitoring of Water PointsIJERA Editor
ย
In recent years, the world has become more sophisticated. Different aspects of todayโs life has been digitized, this include; business, education, health, communication and numerous community services. With the existing extended coverage of cellular networks, most services are constantly deployed to be accessed via mobile phones, as they are also the most pervasive pocket carried devices. Though, both regular and smartphone can be used to convey the basics of mobile based services such as mobile banking, calling and text messaging, smartphone goes extra mile. While regular phones are still the better choice for some, smartphones are tremendously taking over the cellphone market. Smartphones are powered by the vast amount of mobile apps available today which offer unprecedented features and functionalities and as well more advanced internet connectivity. To ensure reliable, sufficient and safe water supply to public, the installed water points need to be well monitored. Quality and quantity parameters of water produced from the water points are constantly tracked to determine if they are within the acceptable range. In case of acute condition, the identified parameters need to be instantly communicated to the District Water Engineer (DWE) for prompt intervention. In this paper we explore the popularity and advantages of smartphones and present a proposed prototype that exploit the power of smartphones in real time monitoring of water points.
IRJET- Design an Approach for Prediction of Human Activity Recognition us...IRJET Journal
ย
The document proposes a framework for human activity recognition using smartphones. It involves collecting data from a smartphone's accelerometer and gyroscope sensors worn on the waist during various activities of daily living. The data is preprocessed and classified using machine learning algorithms like Naive Bayes, logistic regression, and SVM. The proposed framework first loads and preprocesses the sensor data, then generates features before splitting the data into training and test sets. Various classifiers are applied and evaluated to select the best performing one for activity recognition. The authors conclude that implementing tri-axial acceleration from sensors provides different accuracy for different algorithms, with SVM achieving maximum accuracy in previous work.
The document describes a study that investigates using gestures as a form of authentication on smartwatches. The researchers collected accelerometer data from smartwatches as users performed different gestures. They extracted time and frequency domain features from the data and used k-nearest neighbors and random forest classifiers to distinguish between gestures and identify individual users performing the same gesture. Through 5-fold cross validation experiments, they found it was possible to accurately classify gestures and identify users with error rates comparable or better than previous gait-based authentication studies. This suggests gesture-based authentication on smartwatches is a viable solution.

Age Estimation And Gender Prediction Using Convolutional Neural Network.pptxBulbul Agrawal
ย
Identifying the attributes of humans such as age, gender, ethnicity, emotions etc. using computer vision have been given increased attention in recent years. Such attributes can play an important role in many applications such as human-computer interaction, surveillance, searching, biometrics, sale of product, entertainment, and cosmetology. Generally, it is possible to classify human life into one of four age groups: Children, Young, Adult, and Old. The image of a personโs face exhibits many variations which may affect the ability of a computer vision system to recognize the gender. In this dissertation, we evaluate the CNN architecture along with the PCA for gaining good performance.

Inspired by this, we introduce a new concept Mobile Behaviometrics, which uses algorithms and models to measure and quantify unique human behavioral patterns in place of human bio-attributes. Behaviometrics algorithms take multiple data from various sensors as input and fuse them to build behavioral models which are capable of producing application specific quantitative analysis on the unique individuals that were the originators of the data.
EyePhone is a system that allows users to control their mobile phone using only their eyes. It tracks the user's eye movements across the phone's display using the front-facing camera. EyePhone detects eye blinks to emulate mouse clicks and activate target applications. It works by first detecting the user's eyes, then tracking eye movements to infer gaze position on the screen. Blinks are detected by applying a threshold to normalized correlation scores from template matching of the user's open eye template. EyePhone was evaluated on a Nokia N810 and shown to accurately track eyes and detect blinks with low computational overhead. Potential applications include eye-based menus and detecting driver drowsiness. Future work could improve performance under different lighting conditions and online
Report: A Model For Remote Parental Control System Using SmartphonesIJCI JOURNAL
ย
The document summarizes a research paper that proposes a model called "RePort" for remotely monitoring children and teens' access and online activities via their computers and smartphones. The 4-layer RePort model includes layers to monitor smartphone usage through call logs, SMS, GPS, WiFi, and Bluetooth; desktop computer usage; social networking activities; and generate reports. It was implemented as an Android app and Windows service to track parameters like time spent, posts, and messages. Experiments validated the model's ability to monitor access behaviors remotely with 93.46% accuracy.
BEHAVIOR-BASED SECURITY FOR MOBILE DEVICES USING MACHINE LEARNING TECHNIQUESijaia
ย
The goal of this research project is to design and implement a mobile application and machine learning techniques to solve problems related to the security of mobile devices. We introduce in this paper a behavior-based approach that can be applied in a mobile environment to capture and learn the behavior of
mobile users. The proposed system was tested using Android OS and the initial experimental results show that the proposed technique is promising, and it can be used effectively to solve the problem of anomaly detection in mobile devices.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the bodyโs response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
