Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Speed Control of truck prototype using PID is one of the methods to control speed by reading the RPM value using an optocoupler sensor with weight, speed, and slope parameters. Those parameters will be processed and the error value gained from the speed is used as the input for the PID method to reduce the error value. This research is expected to be an innovation in feature implementation using speed control for heavy vehicle initiated by using a truck prototype with 1:11 scale dimension from the real truck. In fact, for testing prototypes Trucks will use lines designed according to the dimensions of the truck prototype. The result of this paper shows that the system could control the speed with up to 96,25% success rate
The problem of protecting the quality of digital text has become a subject of concern in recent years. In particular, digital text security plays the pivotal role for disseminating the electronic material through the Internet. Watermarking is a valuable method for securing digital document information since it addresses the issue of distortion, replication, unauthorized access and breaches of security. The rapid development which is now evident in knowledge exchange and access is the product of the Internet extensive use. As regards to various forms of digital data, this paper is the most complex and challenging medium for the application of watermarking process. Text watermarking is a very challenging task and the relevant works in this area are still limited. Extensive research must be worked out to ensure some major points such as effective evaluation, analysis, and implementation. This paper discusses the theory, technique, and implementation of text watermarking, including meaning description, embedding and extraction techniques, specifications, watermarking strategies and languages which has been used. Moreover, this paper gives a short summary of steganography and cryptography techniques which have been proposed for implementing the text watermarking. Finally, this paper also aims a to discuss the scientific issues transparently and the future work directions
The steganography and watermarking systems are cousins in information security which belong to the same family of data, where between of them have a common feature with its own characteristics. The main objective of digital watermarking is to deal with image authentication, while data hiding is the basic target for steganography. Both systems are focusing on image security. During the great computer revolution and the development of the communications network, it became difficult to control the security of the data transmitted between the sender and the authorized receiver. Therefore, there must be a robust system that protects these confidential data. Therefore, a lot of researchers develop different methods of steganography and watermarking using two different domains, spatial domain, and frequency domain. This paper discusses a comprehensive comparison of methods used in the areas of steganography and watermarking in a spatial domain only
Internet of Things (IoT) and Cloud computing are extremely distinct technologies which are by now playing an important role in our life. It is expected that adopting and using them would be more and more common, that makes them significant components for the Future Internet (FI).The upcoming internet-associated revolution is almost there with the existence of the IoT. IoT empowers connection and communications among tons of devices between themselves to exchange information, knowledge, and data that promotes the quality of our daily lives. Alternatively, appropriate, upon-request, and adaptable network access is provided by Cloud Computing, as a result, makes it possible to contribute computing resources which helps dynamic data be integrated from a variety of data sources. However, Cloud Computing and IoT in FI cannot be implemented without an abundance of issues and problems. In this research paper, we will be endeavoring to outline and put light on the prime and main concepts of the Cloud Computing and IoT
Evaporative cooling is a good alternative of refrigeration cooling systems. This system is environmentally friendly and consumes low electrical energy. However, this system has some disadvantages which is greatly affect on the performance of the system. One of these problems is the affected by external conditions (humidity) makes space uncomfortable and reduces the effectiveness of evaporative cooling. This paper will focus on overcome this problem and improving the performance of the system. An evaporative cooling system was combined with heat recovery and desiccant in order to improve the performance of the system in a humid condition. The unit was constructed and installed at University of Technology in Baghdad. The system includes ducting, desiccant bed, plate heat exchanger (heat recovery), centrifugal fans and heaters. This is accomplished through reducing the moisture imposed on the cooling unit, as a result of handling the latent load of air (by desiccant material). Three air flow rate of supply in desiccant were studied (0.48, 0.61, and 0.73 m³/s). Four regeneration air flow rate in desiccant were studied (0.15, 0.28, 0.49 and 0.59 m³/s). The results show adding the desiccant material and heat recovery system could improve the performance of the system by 106 % (in a humid condition W=20.86 g/kg)
