Multiple description video coding for stereoscopic 3D

In this paper, we propose an MDC schemes for stereoscopic 3D video. In the literature, MDC has previously been applied in 2D video but not so much in 3D video. The proposed algorithm enhances the error resilience of the 3D video using the combination of even and odd frame based MDC while retaining good temporal prediction efficiency for video over error-prone networks. Improvements are made to the original even and odd frame MDC scheme by adding a controllable amount of side information to improve frame interpolation at the decoder. The side information is also sent according to the video sequence motion for further improvement. The performance of the proposed algorithms is evaluated in error free and error prone environments especially for wireless channels. Simulation results show improved performance using the proposed MDC at high error rates compared to the single description coding (SDC) and the original even and odd frame MDC

Antioxidant properties of stingless bee honey and its effect on the viability of lymphoblastoid cell line

Research on the medical benefit of stingless bee honey (kelulut honey) is rather new although it has been used as traditional food and additive for ages. The primary objective of our study was to evaluate the antioxidant properties of kelulut honey and its effect on lymphoblastoid cell line. We analysed the antioxidant properties of kelulut honey by ferric reducing antioxidant potential assay, total phenolic and flavonoid contents using UV spectrophotometry. The total phenolic content, total flavonoid content and ferric reducing antioxidant potential of Malaysian kelulut honey produced by Trigona spp. were found to be 844.45 mg RE/kg honey, 78.29 mg RE/kg honey and 1132.66 mM FE/kg honey, respectively. Our findings showed a strong correlation between total phenolics and flavanoids contents with its antioxidant potential at R2 = 0.920 and R2 = 0.951, respectively. The effect of honey on cell viability of lymphoblastoid cell line (LCL) was also investigated. The cells were cultured in RPMI-1640 medium supplemented with 0 - 500 μg/mL of kelulut honey for 24 hours. Cell viability was quantitated using 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, MTS assay showed that honey supplementation boosted the viability of LCL up to 164.64% (p< 0.01). The significant increase in cell viability might be modulated by the antioxidant properties of kelulut honey

New Adaptive Data Transmission Scheme Over HF Radio

Acceptable Bit Error rate can be maintained by adapting some of the design parameters such as modulation, symbol rate, constellation size, and transmit power according to the channel state.<br />An estimate of HF propagation effects can be used to design an adaptive data transmission system over HF link. The proposed system combines the well known Automatic Link Establishment (ALE) together with variable rate transmission system. The standard ALE is modified to suite the required goal of selecting the best carrier frequency (channel) for a given transmission. This is based on measuring SINAD (Signal plus Noise plus Distortion to Noise plus Distortion), RSL (Received Signal Level), multipath phase distortion and BER (Bit Error Rate) for each channel in the frequency list. Channel condition evaluation is done by two arrangements. In the first an FFT analysis is used where a pilot signal is transmitted over the channel, while the data itself is used in the second arrangement. Passive channel assessment is used to avoid bad channels hence limiting the frequency pool size to be used in the point to point communication and the time required for scanning and linking. An exchange of channel information between the transmitting and receiving stations is considered to select the modulation scheme for transmission. Mainly MPSK and MFSK are considered with different levels giving different data rate according to the channel condition. The results of the computer simulation have shown that when transmitting at a fixed channel symbol rate of 1200 symbol/sec, the information rate ranges from 2400 bps using 4FSK up to 3600 bps using 8PSK for SNR ranges from 11dB up to 26dB.<br /

THE DISTRIBUTION AND BIODIVERSITY OF FISHES IN LEBAK PAMPANGAN SWAMP SOUTH SUMATRA PROVINCE

This research was conducted to evaluate the fish distribution and biodiversity within three types of swamp ecosystem with different water sources in Pampangan Sub-district during July to December 2011. The field observation were conducted in three different types of swamp. Ecological data and samples were collected from three sampling points in each swamp type. Parameters including local distribution, diversity index, similarity index, evenness and species richness, were analyzed. The results show a number of 9,723 fishes corresponding to 46 species were collected, the fish categorized into 16 families belonging to five orders. Eight species were found in all type of swamps i.e. Mystus nemurus, Channa striata, Cyclocheilchthys apogon, Cyclocheilichthys armatus, Pristolepis fasciata, Puntius lineatus, Osteochillus hasselti, and Trichogaster pectoralis. A diversity index of fishes in Pampangan Swamp ranged from 2.31 to 2.85, indicating moderate values. The evenness index was high more than 50%. The highest similarity was found between type 1 and type 3 of (0.43). The highest diversity index (2.85) found in type 2 of swamp indicates the swamp in more stable condition

State of catecxolaminergine systems of the brain in forming of sydnocarb psychosis.

Violations of mnestic reactions are one of substantial signs of disorders of nervous activity. On the basis of it, as a criterion of forming of experimental psychosis, in our supervisions, the state of processes of conditionally-reflex memory was studied in rats. To cover up mechanisms of derangements of conditionally reflex activity in the process of forming of psychotic symptomatic complex, maintenance of adrenalin, noradrenalinum and neurospecific albumen S - 100 in the brain structures, that take a direct part in the processes of memory was studied. Derangements of cognitive function, that are the result of neurotoxic action of sydnocarb, are related to reduction of maintenance of noradrenalinum in the frontal cortex, as well as adrenalin in the pons varolii. That is, sydnocarb psychosis is accompanied by reduction of activating role of the cortex and trunk structures, negatively affecting the state of mnestic reactions. In the hippocampus and striate body excitation causes violation of memory processes and on the contrary, concentration of noradrenalinum rose. Thus, the presented model of experimental psychosis, created by subacute introduction of sydnocarb, is an adequate and alternative methodology of psychotic disorders forming in animals resulted from direct participation of the catecholaminergetic systems of CNS

UNIFIED TOPOLOGICAL FRAMEWORK FOR RETRIEVING 2D AND 3D MULTI-SCALE SPATIAL INFORMATION

Different applications or users need different model (differ requirement on level of details; geometry and information), less focuses in topological element. Improper manage geometry, attribute and topology elements in multi-scape environment will cause data repetition/redundancy, storage capacity and performance issues. This research focuses on utilizing topological graph which is important for various Geographical Information Science applications such as 3D indoor, network analysis, and sharing information/attribute from multiple level of details (LoD). A conceptual framework towards a unified data structure/model for representing several levels of details (LoDs) which integrates 2D and 3D topological and geometrical spaces in a single view is presented. The proposed framework has a potential of adopting into the CityGML/IndoorGML standards with representing different CityGML LoDs in a single view representation. Potential applications of the proposed conceptual framework including solar energy and utility mapping are discussed
