The spatial resolution of micro-XRF can be improved by oversampling and image restoration techniques.

Ticagrelor is a BCS class IV drug that inhibits platelet action by reversibly binding to the P2Y12 receptor. One of major challenges faced (low solubility, low permeability) lower dissolution rate leading bioavailability. The bioavailability marketed formulation ticagrelor approximately 36%. Researchers have come up with various techniques improve II and formulations as an integral part develop...

In many image processing applications the image quality should be improved to support the human perception. The image quality evaluation by the human observers is, however, heavily subjective in the nature. Different observers judge the image quality differently. In many cases the relevant part of image information which is perceived by the observer should reach a maximum. In this work we prese...

In this paper, block-level reconfiguration techniques are proposed for content-addressable memories. The CAM words and redundant words are divided into blocks and reconfiguration is performed at the block level instead of the conventional word level. The reconfiguration mechanism used to implement our technique requires negligible hardware overhead. According to simulation results, the hardwar...

Image enhancement methods are widely used to improve the quality of image by improving its appearance. Usually the images taken by digital cameras are different from the original true color image in terms of color and brightness of the scene captured. Various factors like non uniform illumination, color of ambient light, low or high contrast, and over exposure or under exposure of some specific...

In 4G cellular system, due to the mobility, proper handoff or handover management is critical to ensure seamless migration from one cell to another cell. Besides of maintaining the connection quality during a handover process, any advanced handover algorithms which can minimize required resources for the connection are critical. When connections need to migrate between heterogeneous networks fo...

Failure of addressing all IEEE 802.11i Robust Security Networks (RSNs) vulnerabilities enforces many researchers to revise robust and reliable Wireless Intrusion Detection Techniques (WIDTs). In this paper we propose an algorithm to enhance the performance of the correlation of two WIDTs in detecting MAC spoofing Denial of Service (DoS) attacks. The two techniques are the Received Signal Streng...

Wired Equivalent Privacy (WEP) is an IEEE 802.11 standard implemented to provide security to data transmitted on wireless networks. In this paper we enhance the WEP security by improving the authenticity, integrity and confidentiality mechanisms. WEP uses static 40 bit as pre-shared secret key for pseudo noise sequence generation. Our method uses dynamic key which keeps changing time to time de...

Magnetic Resonance Image is one of the best technologies currently being used for diagnosing brain cancer at advanced stages. This paper proposes a novel approach for the MRI image enhancement, which is based on the Modified Tracking Algorithm, Histogram Equalization and Center Weighted Median (CWM) filter. This method consists of two approaches. The first approach is applying the modified trac...
