In this paper, we propose a localization technique for smartphones in indoor environments. This technique can calculate the coordinates of a smartphone using existing illumination infrastructure with light-emitting diodes (LEDs). The system can locate smartphones without further modification of the existing LED light infrastructure. Smartphones do not have fixed position and they may move frequently anywhere in an environment. Our algorithm uses multiple (i.e., more than two) LED lights simultaneously. The smartphone gets the LED-IDs from the LED lights that are within the field of view (FOV) of the smartphone’s camera. These LED-IDs contain the coordinate information (e.g., x- and y-coordinate) of the LED lights. Concurrently, the pixel area on the image sensor (IS) of projected image changes with the relative motion between the smartphone and each LED light which allows the algorithm to ca...

Exchanging information about the relative directional position of each vehicle together with front and rear-facing direction is significant for fast, accurate and reliable communication. Radio Frequency (RF) (causing extensive interference) or expensive laser (Laser) that is also harmful to the human body are the currently available technology for vehicular communication purposes. Some existing technologies are also using visible light (i.e. LEDs) communications (VLC). But these technologies have the limitation of fast object detection and multiple objects detection as well as maintaining communication simultaneously. However, ensuring high temporal and spatial detection resolution has become one of the challenging tasks for OWC. This paper proposes an image sensor based OWC technique to ensure high temporal and spatial resolution based on VLC system. We proposed an algorithm to support multiple objects detection and communication principal in temporal and spatial condition. We have simulated different scenarios related to spatial and temporal condition using Matlab simulation. The results reveal that our proposed method ensure high temporal and spatial resolution criteria. After all, it also provides secure and fast communication at critical and multiple objects condition efficiently without deploying any tracking method.

Invisibility is a new term for ISC to adopt a communication process between light emitting device, for instance, display and image sensor (e. g: smartphone camera) without notifying the users of the data that is embedded in the image of the display. Although several method has been suggested for invisible communication between display and camera, this work proposes a new mechanism to transmit data from the display image to image sensor receiver. The intensity of the pixels in an image is varied over a period sequentially that the changes can be converted to a signal for communication. The derived signal from the sequential changing of the pixels can be compared to the RF signal in case of communication aspect. In addition, the idea of MIMO has been applied in the communication with a view to removing the shortcomings of low data rate issues of the ISC technology. The performance analysis of our proposed scheme illustrates the practicability with the advantages of the communication methodology.

A compound library collected from natural sources in Australia was screened for antimicrobial activity against a panel of Gram-positive and Gram-negative bacteria. Two natural products psammaplysins F (1) and H (2), inhibited the growth of different Gram-positive strains by 80% or more. The activity of these compounds, isolated from marine sponge Pseudoceratina is related to the amine at position C20, where substitution to a urea group reduced the antibacterial activity by 3-fold (psammaplysin G [3]). The MIC values for (1) and (2) were 42-45 µM against penicillin-resistant S. aureus, and between 40-80 µM against two strains of methicillin-resistant S.aureus (MRSA). Morphological evaluation of treated S. aureus using 3D-structured illumination microscopy indicates that psammaplysin F (1) inhibits equal partitioning of DNA into each daughter cell. Indeed, this is the first report of ...

In case of heat induced HRBC heamolysis, the plant extracts also showed significant activity where the values of inhibitory actions were 14.46 ± 0.344, 28.23 ± 0.315, 25.18 ± 0.303, 17.09 ± 0.365, 13.44 ± 0.470% for methanol extract, pet-ether, carbon tetrachloride, chloroform and aqueous soluble partitionates respectively.Conclusion It can be postulated from the observed results that the membrane stabilizing action and inhibition of erythrocyte lysis property of E. rubiginosum may be the possible mechanism of action of its anti-inflammatory activity. So, further studies are suggested to evaluate the anti-inflammatory and analgesic activities of the plant.

Diets containing sugar beet bagase, wheat bran, brewer yeast, and others with wheat bran and palletized soybean protein from Brazil were tested. Diets based on soybean protein have shown promising results regarding pupal recovery, pupal weight and adult emergence. Soybean bagase in the form of pellets with 60% of protein can be a very important substitute for other expensive sources of protein.

When tested against two strains of methicillin resistant Staphylococcus aureus (MRSA), the minimum inhibitory concentrations (MICs) for psammaplysin F (40-80μM) were similar to the structurally-related alkaloid psammaplysin H (2). Psammaplysin F (1) increased membrane permeability by two to four-fold compared to psammaplysin H (2) or control-treated bacteria, respectively. Unlike psammaplysin H (2), we show that psammaplysin F (1) inhibits equal partitioning of DNA into each daughter cell, suggesting that this natural product is a unique prokaryotic cell division inhibitor.
