Data Alignment for Data Fusion in Wireless Multimedia Sensor Networks Based on M2M

Advances in MEMS and CMOS technologies have motivated the development of low cost/power sensors and wireless multimedia sensor networks (WMSN). The WMSNs were created to ubiquitously harvest multimedia content. Such networks have allowed researchers and engineers to glimpse at new Machine-to-Machine (M2M) Systems, such as remote monitoring of biosignals for telemedicine networks. These systems require the acquisition of a large number of data streams that are simultaneously generated by multiple distributed devices. This paradigm of data generation and transmission is known as event-streaming. In order to be useful to the application, the collected data requires a preprocessing called data fusion, which entails the temporal alignment task of multimedia data. A practical way to perform this task is in a centralized manner, assuming that the network nodes only function as collector entities. However, by following this scheme, a considerable amount of redundant information is transmitted to the central entity. To decrease such redundancy, data fusion must be performed in a collaborative way. In this paper, we propose a collaborative data alignment approach for event-streaming. Our approach identifies temporal relationships by translating temporal dependencies based on a timeline to causal dependencies of the media involved.

Drought is a major abiotic stress that limits rice productivity in rain-fed and upland ecosystems. African rice, Oryza glaberrima, has low yields but is tolerant to drought and other stresses. We evaluated 513 BC2F3progenies from alien introgression lines (AILs) that were derived from crosses of Oryza sativa (IR64) × O. glaberrima. They were assessed for yield and other traits when grown under drought at two locations. Such conditions reduced grain production by 59% compared with the recurrent parent (IR64). However, 33 AILs had higher yields, thus demonstrating their potential as genetic material for transferring drought-related traits from O. glaberrima to O. sativa. A set of 200 AILs was selectively genotyped with 173 simple sequence repeat and sequenced tagged site markers. Molecular analysis showed that a mean of 4.5% of the O. glaberrima genome was introgressed in BC2F3 AILs. Our analysis revealed 33 quantitative trait loci (QTLs;including 10 novel) for different traits. O. glaberrima contributed 50% of the alleles to those newly identified QTLs, with one for grain yield per plant (ypp9.1) being new. A QTL at RM208 on chromosome 2 positively affected yield under stress, accounting for 22% of the genetic variation. Our identification of drought-related QTLs for yield and yield components will be useful to future research efforts in marker-assisted selection.

Philippine pigmented traditional rice varieties (TRVs) ofer potential novel genes for genetic improvement. In this study, forty-three pigmented traditional rice varieties (TRVs) from Region X, XII and XIII in Mindanao were evaluated using 47 agromorphological (22 qualitative and 25 quantitative) traits, grain chemical properties, disease reaction, insect pests, and 64 SSR markers. The standardized Shannon–Weaver diversity index for phenotypic diversity averaged at 0.30 for qualitative and 0.88 for quantitative traits. Desirable traits observed in the TRVs include erect fag leaf, pubescent leaf blade, and strong culm for lodging resistance. Three TRVs, Malagkit (CollNo. 4555), Dinorado (CollNo. 11071), and Canayo (CollNo. 12794) showed resistance to blast. While Kabuyok (CollNo. 1091), Kabuyog (CollNo. 11052), Dinorado (CollNo. 12786), Lubang (Red) (CollNo. 4541), Manganahaw (CollNo. 4570), Palawenyo (CollNo. 6361), Boringan (CollNo. 4291), Mixture from Kabuyok (CollNo. 11070) and Mimis (CollNo. 1092) recorded intermediate resistance to whiteheads. Tapul (CollNo. 5156) was identifed to have blast resistance with desirable grain chemical properties: intermediate amylose content, low gelatinization temperature and medium cooked rice. The PIC values revealed that RM26550, RM28166, RM10665, RM27492 and RM23251 could be the best markers for genetic diversity estimation of these TRVs. The diversity at gene level showed average of 3.48 alleles ranging from 2 to 11 per locus. Mean gene diversity (H) value for all SSR loci was at 0.34, indicates moderate genetic diversity of TRVs used in the study. These pigmented TRVs can be tapped for pests/diseases resistance, and grain quality research, direct utilization or as parents in specifc breeding purposes.
