UBLS - USER-BASED LOCATION SELECTION SCHEME FOR PRESERVING LOCATION PRIVACY
Get PDFDue to the wide availability of location-based services (LBSs) that enable many applications to provide user tailored services, it becomes possible to trace the locations of an individual by an adversary, especially when the LBS server is distrusted, which violates the user’s privacy. Therefore, we propose, in this project, a user-based location selection scheme (UBLS) to hide the users’ locations using k-anonymity to preserve users’ privacy. The proposed scheme uses the concept of dummy locations to hide the real locations of the users, but on top of that, it selects the dummy locations based on the users that exist in these locations. Moreover, we propose an attacker location exclusion (ALE) algorithm that can be used to attack the existing location privacy-preserving schemes. We also propose a new metric, namely location privacy level (LPL), to qualify the ability of the malicious LBS server to reduce the privacy level of the requester. Our envisioned UBLS scheme is evaluated with extensive computer-based simulations. Comparing to the existing schemes in the literature that preserve location privacy, our proposed UBLS demonstrates performance improvement in terms of entropy, cloaking region, and location privacy level metrics
BRAIN TUMOR DETECTION FROM MRI IMAGE USING DIGITAL IMAGE PROCESSING
Get PDFBrain tumor is the main threat among the people. But currently, it become more advanced because of the many Machine Learning techniques. Magnetic Resonance Imaging is the greatest technique among all the image processing techniques which scans the human body and gives a clear resolution of the tumors in an improved quality image. The fundamentals of MRI are to develop images based on magnetic field and radio waves of the anatomy of the body. The major area of segmentation of images is medical image processing. Better results are provided by MRI images than CT scan, Xrays etc. Nowadays the automatic tumor detection in large spatial and structural variability. Recently Convolutional Neural Network plays an important role in medical field and computer vision. One of its application is the identification of brain tumor. Here, the pre-processing technique is used to convert normal images to grayscale values because it contains equal intensity but in MRI, RGB content is included. Then filtering is used to remove the unwanted noises using median and high pass filter for better quality of images. The deeper architecture design in CNN is performed using small kernels. Finally, the effect of using this network for segmentation of tumor from MRI images is evaluated with better results

Get PDFThe biblical book of Genesis contains a description of the creation of the world, which is similar in large measure to the order of Creation known to science today. This article offers an explanation as to how those who wrote the Old Testament could have known the quite accurate order of Creation they set down in writing
The Changing Face of International Relations: Adapting to Global Governance Challenges
Get PDFThe landscape of international relations is undergoing a profound transformation in the face of unprecedented global governance challenges. This article delves into the evolution of the field, tracing its historical roots and examining how it is adapting to the complexities of the contemporary world. We explore the dynamic interplay of historical events, emerging technologies, and shifting power dynamics that are reshaping the traditional paradigms of international relations. From the challenges posed by climate change, cybersecurity, and pandemics to the rise of non-state actors and the impact of technological advancements, this article provides a comprehensive analysis of the forces at play. Moreover, we investigate the changing role of international institutions and the innovative approaches, such as public-private partnerships and collaborative networks, that are emerging to address these challenges. As we navigate the uncharted waters of the 21st century, understanding and adapting to this changing face of international relations becomes imperative for a world seeking effective global governance

Design and Development of Two Wheel Drive Track Spy Robot with Night Vision Camera
Get PDFThe design and development of a 2-wheel drive track spy robot arise from the increasing demand for advanced surveillance systems in various domains such as military operations, security applications, and exploration missions. There is a need for a compact and agile robot that can navigate challenging terrains, gather visual and auditory information discreetly, and transmit data in real-time. The existing surveillance technologies often face limitations in terms of mobility, stealth, and adaptability to diverse environments. The two-wheel drive track spy robot aims to overcome these limitations by leveraging the advantages of a compact, track-based design. This enables enhanced manoeuvrability over rough surfaces, noise reduction, and the ability to traverse obstacles efficiently. By designing and developing a 2-wheel drive track spy robot, it is expected to provide a cost-effective and versatile solution for surveillance and reconnaissance applications. The resulting system will enable improved situational awareness, reduced risks to human operators, and enhanced operational capabilities in both civilian and military scenarios
Cardiac Complications Induced by Biliary Diseases: Clinical Manifestations, Pathogenesis, and Treatment Strategies for Cholecardia Syndrome
Get PDFAmong the most prevalent digestive disorders are gallbladder and biliary diseases (GBDs). As people's diets havechanged and medical diagnostic technology has advanced steadily, links between GBDs and several other organs haveprogressively come to light. Cholecardiasyndrome, which targets the heart as a major target for GBD problems, hasreceived particular attention. Nevertheless, there is currently no comprehensive study on the pathophysiology andaccompanying clinical symptoms. Arrhythmia, myocardial damage, acute coronary syndrome, and heart failure are allprevalent in the general population, according to this study, which included the most current reports of cholecardiasyndrome types. Additionally, the clinical diagnostic rate of Alagille syndrome linked to gene mutation and intrahepaticcholestasis of pregnancy (ICP) is rising. Thus, more information was provided on the underlying pathophysiology,which included aberrant bile acid secretion, gene mutation, translocation, and deletion (JAG1, NOTCH2, ABCG5/8,and CYP7A1), nerve reflex, and autonomic neuropathy. In order to support clinical diagnosis and treatment, the clinicalmedication and potential treatment measures represented by ursodeoxycholicacid were finally summarized

Optimizing DSRC Systems through Combined Similarity-Oriented Logic Simplification and Manchester Encoding
No full textThe significance of encoding strategies in communication systems cannot be overstated, with methods such as Manchester and FM0 encoding playing crucial roles in various applications. Each strategy exhibits distinct operations tailored to specific requirements. This paper introduces the Similarity-Oriented Logic Simplification technique (SOLS), which integrates design and synchronizes tasks, coupled with the use of Differential Manchester Encoding (DSRC) to maintain DC balance and signal reliability. The combination of these techniques aims to reduce the number of transistors and preserve DC balance. The current work focuses on achieving an integrated design of FM0 and Manchester encoding to address shortcomings in traditional methods. This approach results in a reduction in the number of hardware components, consequently minimizing the overall area occupied by additional functionality in Dedicated Short-Range Communication (DSRC) systems
EXPERIMENTAL STUDY ON REINFORCED CONCRETE COLUMN STRENGTHENED WITH FERROCEMENT JACKET
Get PDF: This investigates the behavior of ferro-cement encased square reinforced concrete (RC) column subjected to monotonically increasing the small eccentric load or axially. Three different types of square jacketing techniques have been studied experimentally to find out the effectiveness of ferro-cement confinement of RC columns against eccentric loading. Six scaled down ferro-cement jacketed specimens (two from each group) and two non jacketed scale down specimens (square column) were tested for this purpose. The result obtained from this study show that the benchmark specimens (column without firrocement encasement) fail with non ductile mode of failure when the load reaches to its peak value, however incase of jacketed specimens load carrying capacity and ductility performance are obtained to be more than those obtained from bench mark specimen
