Abstract

The successful software project can be defined as the project that meets the planned quality, cost, schedule, and effort. It has been suggested that there are many reasons which might lead to software project success.  Several success and failure factors for particular projects were discussed in the literature. This paper aims to identify the most common success factors through reviewing a set of software project reports and case studies. In order to fully understand reasons behind the project success, the reasons behind project failure and the definition of failure itself are discussed. Furthermore, case studies of successful and failed software projects are described. This paper also investigates techniques that have been developed to increase software project success rate and decrease probable failures.

Abstract

Workflow scheduling is one of the important issues in implementing workflows in the cloud environment. Workflow scheduling means how to allocate workflow resources to tasks based on requirements and features of the tasks. The problem of workflow scheduling in cloud computing is a very important issue and is an NP problem. The relevant scheduling algorithms try to find optimal scheduling of tasks on the available processing resources in such a way some qualitative criteria when executing the entire workflow are satisfied. In this paper, we proposed a new scheduling algorithm for workflows in the cloud environment using Cuckoo Optimization Algorithm (COA). The aims of the proposed algorithm are reducing the processing and transmission costs as well as maintaining a desirable load balance among the processing resources. The proposed algorithm is implemented in MATLAB and its performance is compared with Cat Swarm Optimization (CSO). The results of the comparisons showed that the proposed algorithm is superior to CSO in discovering optimal solutions.

Abstract

Encryption of digital color image is the process of conversion original digital color image into an encrypted one to protect the image from hacking or to prevent an authorized person to get the valuable information located in the color image. The process of color image encryption-decryption is very important issue in human activities and here in this paper we will introduce a new simple, efficient and highly secure method to be used for color image encryption-decryption. The proposed method will be tested and implemented, the efficiency parameters of the proposed method will be calculated and will be compared with other methods parameters to prove the efficiency issues of the proposed method.

Abstract

The Ministry of Defence in Malaysia has realized a lot of information technology venturing into the world of healthcare for armed forces. From time to time, the majority of these successful healthcare systems are increasingly aware of the extent and success of its operations. Along with IT growth, there is a need for excellent technical capability as well as integrated, centralized, comprehensive and intensive health information systems for armed forces in Malaysia. However, given the success rate in the application of transverse health information system is very high, it is significant to identify the user adoption factor to increase the success rate. Thus, this paper attempt to identify user adoption factors among the medical and clinical personnel’s which Malaysian Armed Forces Hospital and Clinics should keep in mind, to ensure the success of health record systems’ implementation. In this article, we propose our proposition for the clinician and medical personnel’s adoption model to answer our research problem.

Abstract

Colour image retrieval, identification and recognition play an important role in vital computerized applications, so creating an image signature which can be used as a key to identify the image is an essential and important problem to be solved. In this paper a new method of image signature extraction will be proposed. The proposed method will be implemented and tested and the experimental results will be compared with other method results to prove the efficiency of the proposed method by mean of creating a unique signature which will require a minimum memory space and a smaller time to extract the signature.

Abstract

Robotics technology is very useful for the lives of many people today. Almost all aspects of his life utilize robotics technology according to the required field. The development of robotics technology has become a higher quality of human life. Perhaps robotics are still less popular among the general public who still thinks robotics are humanoid robots (robots or human machines). Robotics has been widely implemented in the real world ranging from the fields of industry, medicine, entertainment, security, to household appliances. In the field of security, robotics has an important role. As the robot principle itself is tireless and has little tolerance, the product in robotics in the security field can be a very useful tool. In addition to facilitate human insecurity, robotics products can also facilitate human in various jobs, such as in the locking doors or walls of anyone who already exists. The development of robotics is in line with the development of computer vision which is increasing its application in everyday life. With this research, is expected to improve security and comfort in the security room. The design of this system using electronic door locks, open source OpenCV and webcam as a unit component.

Abstract

Ponorogo district, in East Java Province, is one area that is often hit by landslides.  In addition to threatening the safety of residents, this landslide caused dozens of houses and public infrastructure to be damaged. The losses caused by this landslide disaster also reached billions of rupiah each year. Integrated of emergency mitigation and response systems for landslides are needed to provide information accurately and widely to the community. This paper proposes a new framework of mitigation and emergency system for landslide in Ponorogo district. The system can analyze, display, explore and store vulnerability data based on web GIS application. The information generated from the mitigation system is a landslide susceptibility map using the analytical hierarchy process (AHP) - Natural break method. The landslide susceptibility index is produced based on 4 factors that cause landslides including slope, soil type, land use and rainfall.  The map displays 4 levels of vulnerability including very low, low, moderate and high. The mitigation system is equipped with information features for the community about handling landslides.  Pearson's Chi-squared test showed the classification class of vulnerability was declared very significant result. Emergency system information in the form of alternative route information and nearest evacuation sites.

Abstract

Data on shipping accident investigations from the National Transportation Safety Committee (NTSC) throughout 2010-2016 of fifty-four accident cases at sea, seventeen of which were accidents caused by collisions on ships in Indonesian waters, act to avoid a collision by detecting an object on the sea surface. Detection object is challenging because so many varieties object on the sea surface. Illumination variations with different seasons, periods, illumination intensity and direction affect the detection of objects directly. A rough sea is seen as a dynamic background of moving objects with size order and shape. All these factors make it difficult to object detection. Therefore, it is possible to conclude that background subtraction on sea surface problem remains open and a definitive robust solution is still missing. In this paper, we have applied a selection of background subtraction algorithms with post-processed to the problem. Experimental results with our dataset verify the high efficiency of our proposed method

Abstract

Scrum is a part of agile software development which also called incremental software development model. Scrum methodology commonly used to overcome uncertain condition and tight deadline. Scrum consists of three roles, they are product owner, development team, and scrum master. Scrum can be implemented on many areas such as development of education mobile application, integration of document management system, strengthen IT development centers, and many others. The successful of Scrum implementation depends on the skill and knowledge of the team members. The Scrum also has several risk factors and therefore needs risk management approaches. A comparison between agile and waterfall model is also discussed. The Scrum performance can also be tested with certain ways.  Scrum used to make sure that all parts of the software can be delivered on time. The other benefits, scrum can make creative and productive workplace, and scrum can also increase business value.
