SKINcure: A Real Time Image Analysis System to Aid in the Malignant Melanoma Prevention and Early Detection
No full textSkin cancer (Melanoma) incidence rates have been increasing for the past three decades. The most important risk factors for melanoma skin cancer are unprotected exposure to UV radiation, and growing melanoma-type moles. However, early diagnosis of malignant melanoma increases the chances for cure significantly. Therefore a real time image analysis system to aid in the malignant melanoma prevention and early detection is highly in-demand. In this poster, we propose a portable real time image analysis system to aid in the malignant melanoma prevention and early detection. We present an image recognition technique, where the user will be able to capture skin images of different mole types. Our system will analyze and process the images and alert the user at real-time to seek medical help urgently

Managing Information Across the Enterprise: Implementing a Program Management Office (PMO)
No full textProgram management offices (PMOs) can help develop and implement organizational improvements. PMOs can increase the efficiency and effectiveness of product and service delivery and help bridge the strategy–execution gap to sustain a competitive advantage. A PMO is one essential element for driving collaborative vision, prioritization, communication, and execution of projects [Allen, 2006]. This article introduces (1) PMO concepts (framework, structure, and procedures), (2) a PMO Case Study Methodology to implement an organization’s PMO, and (3) concepts in case method research for the classroom experience that could be used in universities’ business, information systems, and enterprise resource planning curricula
Brain Signals Analysis during Concentrated and Diluted Modes
Get PDF© ASEE 2015One way of avoiding procrastination is by activating areas within the brain where we switch from one mode of thinking to another. Scientists say the primary cause of procrastination is that people tend to become uncomfortable when they are not sure what to do. However, the discomfort can be changed. Scientists have found that stimulating the brain from an unpleasant to a happy thought is possible by fooling the brain, even it is temporary. This study focuses on brain signals during people’s interaction with non-familiar situations (diluted mode), monitors their performance during familiar activity (concentration mode), and analyzes their performance. Cerebral cortex signals are analyzed from the participant using electroencephalography (EEG). The brain can be trained to deal with unexpected scenarios that lead to frustration. This study can help improve a person’s life by training their brain to take proper action to deal with their discomfort
Design and Simulation of an Electrostatically-Driven MEMS Micro-Mixer
No full textBio MEMS ( Biology Micro-electro-mechanical Systems) focus on some micro-fabricated devices including electrical and mechanical parts to study the biological system such as new polymer-based drug delivery systems for anti-cancer agents, specialized tools for minimally invasive surgery, novel cell sorting systems for high-throughput data collection, and precision measurement techniques enabled by micro-fabricated devices. Especially some micro-liquid handling devices like micro-pumps, active and passive micro-mixers that can make two or more micro-fluids mixing completely, with the chaotic advection. This kind of rapid mixing is very important in the biochemistry analysis, drug delivery and sequencing or synthesis of nucleic acids. Besides, some biological processes like cell activation, enzyme reactions and protein folding also require mixing of reactants for initiation, electrophoresis activation. Turbulence and inter-diffusion of them play crucial role in the process of mixing of different fluids. In this report, it will introduce a new kind of electromechanical active micro-mixer, which includes two inlets and one outlet under the electrostatic driven voltage. Two different fluids will enter the micro-mixer and shows different colors separately blue and red. Choosing the ANSYS for the simulation of the fluids running in the micro-mixers, we can see nearly 100% fluids that have been mixed. ANSYS is used to show the effectiveness of the micro-mixer
Biocompatibility of PCL-Graphene Nanostructured Scaffolds with Mouse Embryonic Stem Cell-derived Cardiomyocytes
No full textSince adult cardiomyocytes are not readily available for clinical use, numerous efforts have been made to derive functional cardiomyocytes from pluripotent stem cells. [1,2]. A variety of cardiovascular tissue engineering strategies have been explored to develop engineered cardiac tissues for in vitro and in vivo applications utilizing fibrous tissue scaffolds, both single polymer scaffolds and hybrids of polymers with hydrogels, coatings or embedded materials[3-9]. While graphene, a single layer carbon crystal, has recently become a material of interest for tissue engineering applications including osteogenic, neural and stem cell differentiation [10-12], its potential for cardiac tissue engineering is yet unknown. The inherent electro-activity of the myocardium makes graphene an especially attractive option for cardiac tissue engineering due to its high electrical conductivity. Thus, a novel hybrid 3D scaffold with graphene has been developed and its effect on the function of stem cell derived cardiomyocytes is examined
Fortified Anonymous Communication Protocol for Location Privacy in WSN: A Modular Approach
No full textWireless sensor network (WSN) consists of many hosts called sensors. These sensors can sense a phenomenon (motion, temperature, humidity, average, max, min, etc.) and represent what they sense in a form of data. There are many applications for WSNs including object tracking and monitoring where in most of the cases these objects need protection. In these applications, data privacy itself might not be as important as the privacy of source location. In addition to the source location privacy, sink location privacy should also be provided. Providing an efficient end-to-end privacy solution would be a challenging task to achieve due to the open nature of the WSN. The key schemes needed for end-to-end location privacy are anonymity, observability, capture likelihood, and safety period. We extend this work to allow for countermeasures against multi-local and global adversaries. We present a network model protected against a sophisticated threat model: passive /active and local/multi-local/global attacks. This work provides a solution for end-to-end anonymity and location privacy as well. We will introduce a framework called fortified anonymous communication (FAC) protocol for WSN.https://doi.org/10.3390/s15030582

An Efficient Video Steganography Algorithm Based on BCH Codes
No full text© ASEE 2015In this paper, in order to improve the security and efficiency of the steganography algorithm, we propose an efficient video steganography algorithm based on the binary BCH codes. First the pixels’ positions of the video frames’ components are randomly permuted by using a private key. Moreover, the bits’ positions of the secret message are also permuted using the same private key. Then, the secret message is encoded by applying BCH codes (n, k, t), and XORed with random numbers before the embedding process in order to protect the message from being read. The selected embedding area in each Y, U, and V frame components is randomly chosen, and will differ from frame to frame. The embedding process is achieved by hiding each of the encoded blocks into the 3-2-2 least significant bit (LSB) of the selected YUV pixels. Experimental results have demonstrated that the proposed algorithm have a high embedding efficiency, high embedding payload, and resistant against hackers
