Used Car Price Estimation: Moving From Linear Regression Towards A New S-Curve Model

A simple linear regression is commonly used as a practical predictive model on a used car price. It is a useful model which carry smaller prediction errors around its central mean. Practically, real data will hardly produce a linear relationship. A non-linear model has been observed to better forecast any price appreciation and manage prediction errors in real-life phenomena. In this paper, an S-curve model shall be proposed as an alternative non-linear model in estimating the price of used cars. A dynamic S-shaped Membership Function (SMF) is used as a basis to build an S-curve pricing model in this research study. Real used car price data has been collected from a popular website. Comparisons against linear regression and cubic regression are made. An S-curve model has produced smaller error than linear regression while its residual is closer to a cubic regression. Overall, an S-curve model is anticipated to provide a better and more practical estimate on used car prices in Malaysia

Effect of ionizing radiation towards human health: a review

This paper reviews the properties, process and effect of ionizing radiation towards human health. Ionizing radiation is a radiation that carries enough energy to liberate electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds such as alpha, beta, gamma, neutron particles and X-rays. The spontaneous disintegration of atoms is known as radioactivity and the excess energy emitted is a form of ionizing radiation. Unstable elements which disintegrate and emit ionizing radiation are called radionuclides. It has many beneficial applications, including uses in medicine, industry, agriculture and research. As the use of ionizing radiation increases, so does the potential for health hazards. Radiation exposure may be internal or external, and can be acquired through various exposure pathways. Different organs have different sensitivity to ionizing radiation. Understanding the effects of radiation on human bodies provide useful information for the development of radiation protection measures

Hybrid LTE-Vanets Based Optimal Radio Access Selection

The access technology selection,that a user can associate with any radio access technology (RAT) with the availability of multiple RATs available,has been intensively investigated by vehicular Ad hoc Network (VANET).In particular it carries and distributes information,inter-communicates and is capable of communicating with other stationary units deployed along roadways.The current study proposed hybrid optimal radio access selection algorithm (ORAS) for LTE/VANETs network. The periodically broadcasted network information supports mobile users to make their selection decisions;mobiles consider their own individual preferences,cost and partial QoS information signaled by the network while making their decision.The switches algorithm between VANET and LTE based on the load value of network and quality of service requirements were proposed.The simulation results have shown that the proposed algorithm has better performance compared with LTE and VANETs separately in terms of packet delivery ratio,latency and application-level throughput

Safety culture in handling radioactive materials for radiation practitioners : a review

Safety culture refers to how safety is addressed and communicated in the workplace. It encompasses the attitudes, beliefs, perceptions, and values of all employees in an organization about safety. A good safety culture can be promoted by management through a commitment to safety, realistic practices for handling hazards, continuous organizational learning and concern for hazards shared across the workforce. The objective of this paper is to reviews the safety culture in handling radioactive sources. The radioactive substances used should comply with the following characteristics where radiotoxicity must be as low as possible, short-living isotopes are preferred to long-living ones and the amounts used must be kept to a minimum. Therefore, the As Low As Reasonably Achievable (ALARA) principle was applied that based on the minimization of radiation doses and limiting the release of radioactive materials into the environment by employing all reasonable methods. Besides that, the ALARA principle is an integral part of all activities that involve the use of radiation or radioactive materials and can help prevent unnecessary exposure as well as overexposure. The three major ALARA principles to assist with maintaining doses are time, distance and shielding. It takes a whole team effort to successfully implement the ALARA in safety culture while doing routine elements of working in handling radioactive materials

The Preferences of Student’s Learning Method Based on Course, Gender and Age: Visual, Audio, Reading & Kinesthetic (VARK)

Different students have different preferences for learning methods. Some of the students might prefer visual or audio reading or kinesthetic learning. It is believed that the student’s preferences of learning methods might help the students understand more about the subject and hence contribute to their academic performance. Therefore, this study investigates whether the students’ preferences for learning methods are influenced by the courses they registered for and the gender, and age of the students. A sample of 341 students from different backgrounds was selected in this study comprised of students from the Faculty of Business and Management, Faculty of Accountancy, Faculty of Graphic Design, and Faculty of Nursing in Universiti Teknologi MARA (UiTM) Puncak Alam. The findings show that course and gender play an important role in student’s preferences for learning methods while age is not the significant variable. There is a very high positive correlation between courses and preferences of learning methods, while age and gender have a high positive correlation toward preferences of learning methods. This study might help educators in tailoring their lectures to the students’ preferences of learning methods, thus contributing to the academic performance of the students
