Abstract: For tag anti-collision algorithm in the current RFID system, considering the problems of tag privacy leakage and tag being tracked, a security solution based on Hash function was put forward. A theoretical analysis and a security evaluation about the proposed solution are also made. Through the analysis and evaluation, it turns out that this solution can prevent tag from privacy leaking, being tracked, cloning and counterfeit.

Abstract: The paper deals with the use of the connection lane on the left of running lane. It is all about its impact on improving traffic flow butt junction, shortening the waiting time required for the safe passage of vehicles on side roads and not the least impact on traffic safety at the intersection with the appearance of the lane. The paper also deals with conflict situations that were identified in the survey.

Abstract: Exhaust noise is one of the noise pollution to the environment and it will cause interference that may harm the activity or balance of human. A muffler is designed to minimize transmission caused by exhaust gases. In this paper, the principle of transfer matrix method is used to analyze the transmission loss. The method is used for developed source code programming to predict muffler performance. The result from programming show excellent agreement with the previous established research paper. This programming is applied for baffle effect to determine transmission loss.

Abstract: Submarine slides can trigger tsunamis with high affecting offshore structures, subsea facilities and human lives along the shoreline. Unfortunately, slide-generated tsunami is a difficult problem due to the source of sliding of mass failure by itself or by the other earthquakes. There are no effective numerical model that could simulate simultaneously all stages of generation, propagation, run-up and impact of tsunami phenomena. Physical understanding of slide tsunami hazards is very poor. We must understand substance of tsunami clearly and how to find methods to reduce damage from tsunami wave. This paper will present a parallel computing based on ParallelSPHysics, it can simulate a comprehensive model of tsunami wave by using Smooth Particle Hydrodynamics method.

Abstract: Geologic sequestration of carbon dioxide (CO2) in deep saline aquifers is one of the most feasible techniques for mitigating the greenhouse effect. However, over-optimistic design of CO2 injection scheme may adversely overwhelm the sealing capability of the cap-rock in the saline reservoir. In this study, we have developed a complex three-dimensional heterogeneous model to study the spatial and temporal distribution and storage of CO2 injection into the saline aquifer structure at Taiwan western offshore. For investigating the mechanisms of CO2 migration in a deep saline reservoir, which was hypothesized as a sequestration site, the result of numerical simulations was analyzed. Numerical simulation of CO2 migration in geologic formations can provide key information for predicting CO2 plumes before conducting field-scale operations or pilot tests. In order to avoid the problems of overpressure in the saline reservoir, the case study employs multi-well injection strategies. The sensitivity analyses based on the two different injection strategies in the western sea of Taiwan show that the locations of CO2 plume front might be from hundreds of meters to kilometers.

Abstract: Changes taking place in project-based manufacturing emphasize the importance of agile manufacturing, product knowledge management and product lifecycle information. The paper describes dependencies between product definition and production strategy covering also other potential areas of research i.e. growth of industrial service business and development of manufacturing and supply networks. As an outcome it can be argued that more research is needed to align product lifecycle management in project-based manufacturing, as well as to cover the evolving information needs of internal and external stakeholders. Due to the increase of industrial services, also services should be included as a part of product definition; the extended product description introduces a new set of requirements that need to be taken into account as a part of product and production strategy definition.

Abstract: Energy is a key factor in the comfort and well-being of people in different countries both developed and developing countries, as well as directly to national security, political, military, economic, social and especially power components and important for economic development in all fields such as agriculture, industry, business, housing, construction, electricity, water, transport and communications by the consumption of energy is directly related to the economic and social development of the country, if developed, the more they need to increase power consumption as well and if used incorrectly and does not save energy, it makes the energy gone very quickly. Therefore, all countries need to find ways to prevent and resolve such problems by requiring conservation measures for energy efficiency in both the short and long term.

Abstract: Current industrial manufacturing or agencies tend to adopt ERP systems into applications to enhance the work of the administration of the organization. The use the ERP system is not easy. They also have to endure the force of employees in an organization that does not change the original work. To the development of corporate ERP is slow. This research focuses on the analysis of problems and issues that come up that I use the ERP system ERP reason to successfully injected problems in the organization.

Abstract: In present, manufacturing organizations in some countries will have to submitinformation to both internal and external to the organization, called circular mail to report newswithin the organization or external relations. Administrative officer is responsibility about to senda circular mail for each organization and will be responsible for receiving letters in paper form orpublication or media message. Then the administrative officer will be read and extracted the letterand send a message in the form of emails to receivers as indicated on the letter. In mailings sendsuch potential attacks from disgruntled individuals; such as a change of email messages duringtransmission or identity thieves use a fake email address to send officials to the other party. If anattack occurs, the organization will make a loss. In terms of stability credibility and security in theuse of corporate email. This paper presents a model and how to send an email or letter online ina format that is more stable and secure by the applied technology of public key cryptography andhash function to encrypt the message to provide stability and security in the mail's circulars online.

Abstract: Reverse Engineering (RE) and Rapid Prototyping (RP) were used for manufacturing cream bottle. Points cloud data of cream bottle was accessed by handheld laser scanner firstly. Then, points cloud data was handed by Imageware software and the three-dimensional model was formed by Solidworks software. Finally, the entity model was manufacturing by RP machine. In the research, rapid prototyping was combined with reverse engineering technology, manufacturing cycle was shorten, production requirements, improve efficiency and other advantages were met.
