Background: Images are widely stored and transformed over public channel for communication, medical purpose or organizational uses. Mostly the images are collected from the remote location, therefore the confidentiality of the data becomes the most important matter of concern. The most convenient way to protect the data (image) is to encrypt it right after the capturing the images from the sensors at remote locations. Th Read More

Background: Mobile Adhoc NETwork (MANET) is a self-configurable network consisting of mobile nodes connected by wireless links according to recent patents. The inherent features of MANETs like- dynamic topology, limited resources and lack of centralized trusted authority make it more vulnerable to attacks than wired networks. Reactive protocols that involve broadcasting of route request (RREQ) messages to their one Read More

Background: Patents reveal that mobile phones are the best possible mode of contact in case of any emergency situation. However, a message such as switched off or out of coverage area on mobile phones may make a caller helpless. There is no way of contacting a mobile user if the user is in a situation of out of range or switched off state due to non-coverage or any technical fault. Objective: This paper proposes a metho Read More

Background: Due to easily available Virus Creation Kits that help in the generation of variants from an original malware in no time on the Internet has led to an exponential growth of the advanced malware. In recent years, the detection of advanced malicious programs like Metamorphic and Polymorphic variants has become a major issue for the Anti-Virus companies due to their concealing property either by mutating their c Read More

Background: Water treatment, important for maintaining clean water among other applications, is still a challenge to improve remediation technologies for eliminating pollution. Ultrafiltration, as one kind of membrane separation processes which play a vital role in water treatment, has been attracted extensive attention for its merits of high-efficiency, low-cost and energy-saving. However, some drawbacks still restrict t Read More

Background: Fluid transport pipelines are subjected to operating conditions that generate their continuous deterioration. The deterioration rate is of great significance when the pipeline is considered a high pressure line (above 200 psi), which can lead to major loss of life and assets in case of any system's failure. Objective: This study seeks for innovative pressure pipeline intervention methods used in industry, like the oil & gas. Me Read More

Background: The fabrication of Micro-holes in hard machining materials is always difficult according to recent patents. The electrochemical drilling process is a good selection for the fabrication of Micro-holes. Methods: In this paper, an electrochemical drilling process for fabricating Micro-holes with high efficiency is introduced, and simulation of the gap electric field and the gap flow field is carried out. Firstly, the model of ultra s Read More

Background: Patents suggest that fault diagnosis is an important technology for maintenance, which is usually employed to avoid system catastrophic damage and ensure reliability. Objective: As traditional diagnosis method was limited in linear systems, a novel diagnosis method was proposed to address hidden failure in nonlinear system. Methods: This method was based on the combination of strong tracking square Read More

Background: The post-tensioned pre-stressed concrete girder is widely used in modern bridge construction. Grouting compactness has a great influence on the safety, reliability and durability of pre-stressed concrete girders. So, it is important to test the grouting compactness of the pre-stressed girder to ensure the construction quality and meet the design requirements. However, there are some defects in the existing m Read More
