Quantum Selective Encryption for Medical Images
No full textTo trade security off for computational complexity, Selective Encryption (SE) in Image Processing denotes an approach which is capable of encrypting an image partially. In other words, it is aimed at turning the visually most important parts of images into meaningless ones, ignoring unimportant regions to have a computationally-efficient technique. Based on BRQI images, in this paper, a novel quantum selective encryption method for medical images is investigated. ROI (Region of Interest) tends to be the most vital part of medical images, which should be protected during the transmissions. The proposed method encrypts this region effectively by manipulating the bitplanes of the images according to a key. Experimental results encompassing correlation of adjacent pixels, histogram analysis and entropy rate analyzed in MATLAB environment demonstrate a good performance. Furthermore, regarding a BRQI image of 2(n) pixels, the time complexity is not more than O(m), where m is length of the key sequence. On no condition does it depend on size of images, bringing about being far more time-efficient compared to its classical counterpart and even earlier studied works found in the literature (full-encryption ones). To the best of our knowledge, this is the first method to introduce a quantum selective image encryption method.

Impact of the Lubricant on a Modified Revolving Vane Expander (M-RVE) in an Organic Rankine Cycle System
No full textThe expansion device is the critical component of micro-to-small scale organic Rankine cycle (ORC) systems, substantially affecting system efficiency and cost. Low isentropic efficiency and lubrication requirements are the main issues associated with using volumetric expanders in ORC systems. Despite lubrication contributing to reducing internal leakages in an expander, it may compromise the performance of the ORC system by adversely affecting the evaporator’s thermal capacity. This study tests a recently developed and modified revolving vane expander (M-RVE) in a micro-scale ORC test rig by implementing an adjustable oil mass flow rate. The impact of the lubricant oil on the performance of the M-RVE prototype is investigated within a wide range of oil circulation rates (OCR). The results demonstrate a negligible improvement in the filling factor for OCRs higher than 1%. Moreover, the shaft power is not considerably sensitive to OCR, while the calculated isentropic efficiency of the expander improves with OCR. Furthermore, the impact of the lubricant oil on the performance of the evaporator is studied, assuming the exact OCR as the expander and measured temperature and pressure similar to the pure refrigerant for the lubricant-refrigerant mixture in the evaporator. The study shows that the evaporator capacity is penalized with OCR, especially for values higher than 1%. Hence, an OCR of about 1% is a good compromise, and it can be used as a guideline for designing revolving vane expanders for micro-scale ORC systems without a dedicated lubricant oil circuit
فاکتورهاي مؤثر بر حاشيه ايمني عابرين پياده در خيابانهاي فاقد علائم راهنمايي و رانندگي
No full textBackground and Objectives: One of the most important factors in traffic engineering is pedestrian crossing safety. Investigating the parameters affecting the pedestrian’s safety margins and their relationship on the identifying the main causes of accidents relate to pedestrians on the streets without the traffic signs and driving has an important role. This article examine some of the factors related to the safety of pedestrians and the relationship between them.
Materials and Methods: For this purpose, the videos were recorded of 56 pedestrians, were evaluated. This study was cross - sectional and conducted on the basis of observational data. Data analysis was performed using SPSS 21 software and linear regression method.
Results: The results obtained from software has shown that the influence coefficients of various factors affecting pedestrian’s safety margin that include waiting time before moving with 0.78, repeat looking at the vehicles before and while crossing with 0.58, looking time at the vehicles before and after passing with 0.73 and passing time with 0.29.
Conclusion: In this case study that has been done in Tehran Motahari street, “The pedestrians waiting time before passing “ were determined as the most important factor affecting the pedestrians safetymargin on the streets without traffic signals.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Get PDFFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
