This paper shows the comparison between several well-known classification algorithms in Machine Learning with the purpose to find the most suitable algorithm to predict the dwelling time i.e., how long a certain tourist should stay in a particular tourist spot. This dwelling time prediction can be adopted for tour and travel agents to provide optimal scheduling for their package tour. The algorithm in question is strictly for classification because in this case, the dwelling time does not require a very specific number of minutes, thus the time can be classified and restricted into several time frames. The origin and features of the dataset are described in this paper as well as the comparison methodology to show the procedure of how the comparison was made. Lastly, the performance results will be used to determine which algorithm to use for this specific case and it will be shown in a form of a graph

This study describes the development of a smart trash bin that separates and collects recyclables using a webcam and You Only Look Once (YOLO) real-time object detection in Raspberry Pi, to detect and classify these recyclables into their correct categories. The classification result rotates the trash bin lid and reveals the correct trash bin compartment for the user to throw away trash. The performance of the YOLO model was evaluated to measure its accuracy, which was 91% under an optimal computing environment and 75% when deployed in Raspberry Pi. Several Internet of Things hardware, such as ultrasonic sensors for measuring trash bin capacity and GPS for locating trash bin coordinates, are implemented to provide capacity monitoring controlled by Arduino Uno. The capacity and GPS information are uploaded to Firebase Database via theESP8266 Wi-Fi module. To deliver the capacity monitoring feature, the uploaded trash bin capacity information is displayed on the mobile application in the form of a bar level developed in the MIT App Inventor for the user to quickly take action if required. The system proposed in this study is intended to be implemented in a rural area, where it can potentially solve the recyclable waste separation problem.

Nowadays we can see nearly everything which was once controlled by human being are being automated using machines and electronics circuits. In this paper, we are mainly concentrating on the use of a cell phone to run a remote controlled robotic arm. We have designed the robotic arm with base rotation, elbow and wrist motion with a functional gripper to pick and place as well as to hold objects. Like the bones in your body, the individual segments are connected together with joints. The decision to pick and place the object will be taken by operator by pressing the cell phone key. By pressing different keys of cell phone the robotic arm can be moves in desire direction such as left, right, up and down. We have used the ATmega328P microprocessor, DTMF and GSM modules for the purpose of remote controlling by cell phone. Proteus 8 for the hardware simulation and Arduino IDE for control part programming as well. This remote controlled robotic arm can be used to reach the places where humans cannot reach such as small tunnels, etc. This solution demonstrates the use of cell phone as a control unit without use of computer.

Widespread use of fossil fuels as a source of energy leads to automobile emissions of CO2 and other greenhouse gases (GHG) that plays a significant role in environmental pollution. A transition from fossil fuel to cleaner and more energy-efficient alternative fuel vehicles such as hydrogen fuel cell vehicles (FCVs), is a vital step in reducing the automobile emission. However, the insufficient charging stations and the long charging time compared to the conventional vehicles have to be overcome before hydrogen fuel-based vehicles can be fully adopted on a mass scale. This paper proposes a method that can count the approximate waiting time by using YOLO real-time object detection to detect how many hydrogen fuel-based vehicles are charging or queueing in the charging station. Therefore, the driver can choose the charging station that has minimal waiting time so that the insufficient charging stations and the long charging time can be managed.

This research will begin by mapping the stages of software development and secure software development so that the comparison of the needs of both parties can be seen, where the application of security concepts will refer to the Software Security Touchpoint, and for the risk side a comparison of risk assessment methods that must support a development secure software, seen from the stages and output that will be generated in the form of security controls. So that a guideline can be produced in making IT security control as a solution in developing secure software based on risk during Software Development Life Cycle.

There are a lot of cases of non-disabled drivers regularly using spaces for people with disability. They often get away with it too unless an authority happens to check while their vehicle is parked there. This project presents a reserve-based parking system in securing the parking spaces for the disabled. In this proposed system a special parking area for disabled will be introduced using current technology such as the internet of things (IoT), and mobile application as a Smart City concept initiatives. By using the reservation system and alarm system, violation of disabled parking system can be avoided. In order to separate normal people and disabled people, we use identification method by using NFC tag reader. After the successful identification process, the user can make a reservation and choose the disabled parking space with their mobile application. The system also uses an alarm system to warn the non-disabled person who wants to park in the disabled parking spot. The implementation of the system, expected to simplify the operations of parking systems, as well as improve the quality of life of the disabled person.

In this paper, we propose a new method to enhance an android security by exploiting a selective management of application permission. To that purpose, we analyze behavior of the current android security, via which we draw out possible vulnerabilities. After that, we develop a tool to implement the selective management of the application permission, witch has a function to give a permission selectively for the application when we install a new application. Via experiment we show validity of the developed tool in solving the drawn vulnerability in the current android security.

As part of the development of information technologies for eco-friendly transportation system, we performed a study on cost-effective bicycle sharing system feasible for developing countries. The sharing system will work based on online registration and real-time monitoring system, using smart phone and passcode. A low budget Kiosk system for bicycle access from the station will be used. This provides efficiency to users as well as the system for smooth and easy operation.

Even though IoT devices for monitoring and managing the environment are already present at national level, vulnerability related to security in these systems still prevails at large. Therefore, it is required to study and implement a feasible security protocol in these systems. In this paper, we tested optimal lightweight cryptography for security enhancement in an IoT based Environmental Monitoring System that monitors and controls the surrounding temperature and humidity. We compared the CPU usage and processing time when various lightweight cryptography was applied. This helped us to conclude that the optimal lightweight cryptography for IoT based system is LEA which is a block cipher.

There is a strong movement to utilize sensor data which are collected by IoT devices on manufacturing facility. Especially, using these data, companies which manufactures and sells the manufacturing facility or buyers require a kind of maintenance systems for easily managing their facilities because they want to minimize a suspension of work caused by a breakdown on the facility. From their perspective, the suspension means unnecessary expenditure. Therefore, they want to quickly recognize that the breakdown has occurred and restart the facility as soon as possible by solving the problem. In this paper, we design the reference model for the manufacturing facility maintenance systems. The purpose of this systems is to reduce the losses caused by the breakdown.

As part of the development of ICT convergence technologies for special education, we implemented a mobile-based disability test application. In this paper, we studied an information visualization method that uses a graph to optimize the display on the screen of mobile devices. The implemented application properly divides the screen of the mobile device, and the test scores obtained from the results of the disability test are displayed in a graph that can be moved left and right using the GraphView library. Test comments are also displayed in a table format that can be simultaneously moved up and down. This provides efficiency to users due to the large amount of data that can be represented.

Though the WiMedia supports higher data rates than other WPAN technologies, a WiMedia device cannot reach other devices that are separated from it by more than 10 m, which is the typical limited transmission range of the WiMedia protocol. In this work, we propose a multi-hop QoS routing protocol to enable WiMedia devices to transmit real-time data to devices that are located out of the transmission range. The proposed routing protocol is a hybrid algorithm, which mixes the table-driven and on-demand routing algorithms, searching one or more routes according to the number of hops to a destination device. WiMedia MAC is potentially capable of learning the existence of neighbor devices by using a beacon frame. By utilizing the neighbors’ information, all devices can create routing entries for devices within 2-hops periodically. For devices beyond the 2-hop range, the newly designed on-demand routing algorithm is applied to multi-hop routing. If a routing entry for a destination device is not listed in the routing table, the source device sends a request packet to 2-hop range devices which could be found in the routing table. Since every device maintains routing entries for 2-hop range devices in the routing table, the request packet is replied in advance before its arrival at the destination device. Also, to decide the optimal route for a destination device, the number of medium access slots (MASs), received signal strength indicator (RSSI) and hop count are utilized to establish a QoS-enabled routing table. We perform ns-2 simulation to investigate the performance of the proposed routing protocol with AODV and DSDV. The simulation results show that the proposed protocol has better throughput and lower overhead than other protocols.

In this work, we developed an application to support Android 4.0 security system permission. Permission of every application that has been installed is represented, which is classified by the level of risk. The developed tool can make users to review the permission of applications, and users can find whether it is malicious or not. This work can be applied to remove the malicious application.

Though WiMedia supports the higher data rates than other WPAN technologies, a WiMedia device cannot reach other devices which are apart from it more than 10 meter; the limited transmission range of the WiMedia protocol. In this paper, we propose a multi-hop QoS routing protocol to enable WiMedia devices to transmit real-time data to devices that is located out of transmission range. The proposed routing protocol is a hybrid routing protocol, which is the mixed protocol of table-driven and on-demand routing algorithm. In the proposed protocol, a route for a device within 2-hop is established by using the table-driven routing algorithm and a route for the device beyond 2-hop is established by using the on-demand routing algorithm. We perform ns-2 simulation to investigate the performance of the proposed routing protocol with AODV and DSDV. The simulation results show that the proposed protocol`s performance is better than AODV and DSDV in terms of the throughput and delay.

In this paper, we studied lightweight cryptography for IoT based Bicycle Sharing System. We maintained a remotely located real time server and four separate stations with kiosk control box system, designed with Internet based IoT devices. Then, we calculated the processing time to unlock the bicycle from each station, once the request was sent to the server. The calculated load and processing time were compared after the application of cryptography algorithm. The comparison helped us conclude that the LEA cryptography showed minimal time difference when applied in a real time system. At the same time, highly secure data transmission was also achieved.
