Semi-automated mobile television interactive application generation based on XHTML and Java ME

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 11/02/2011.Mobile Digital TV (MDTV), the hybrid of Digital Television (DTV) and mobile devices (such as mobile phones), has introduced a new way for people to watch DTV and has brought new opportunities for development in the DTV industry. Nowadays, the development of the next generation MDTV service has progressed in terms of both hardware layers and software, with interactive services/applications becoming one of the future MDTV service trends. However, current MDTV interactive services still lack in terms of attracting the consumers and the service creation and implementation process relies too much on commercial solutions, resulting in most parts of the process being proprietary. In addition, this has increased the technical demands for developers as well as has increased substantially the cost of producing and maintaining MDTV services. In light of the aforementioned situation, the Thesis has contributed to this field, by proposing an innovative MDTV service creation and consumption system based on XHTML and Java ME. On the head-end it introduces a semi-automatic creation mechanism to facilitate a less technical and more efficient interactive service creation process. This enables designers and creative individuals to be actively involved in the MDTV service creation process and to develop interactive-rich MDTV service. On the client-end it employs an open-source software environment as the interactive service MDTV consumption platform, rendering the MDTV service implementation process as less proprietary as possible. Furthermore, the Thesis offers a discussion on the different MDTV interactive application models currently used and based on the proposed software, a novel MDTV service presentation method is further introduced and adopted instead of the Rich Media and ECMAScript based methods. Finally, a series of qualitative testing procedures have been implemented with regards to conducting an essential evaluation on the operability of the proposed software system

Semi-automatic creation of graphically-rich mobile television services and applications using an XHTML browser and J2ME

Mobile Digital Television (MDTV) has increasingly become one of the key topics of interest within the DTV industry. This has been particularly successful with regards to the definition and rollout of different content and service distribution standards such as DVB-H, DMB and several others. This is in contrast to the application layer (with regards to middleware and service creation) of the MDTV system, where research and development lags behind. This paper presents work that aims at integrating the service implementation reference, the Application Model (AM), in different MDTV standards by proposing a compatible MDTV service creation process that employs XHTML and Java ME on the service presentation layer; where interactive MDTV services are created using a semi-automated service development tool. With the implementation of this process, this paper aims at developing a universal open-standard environment as an enhancement to the MDTV service development, that on one hand enables more creative and design oriented people with little technical expertise to be involved in the service creation process and on the other hand speeds up the process of creating interactive MDTV services

Fusing Local Shallow Features and Global Deep Features to Identify Beaks

Cephalopods are an essential component of marine ecosystems, which are of great significance for the development of marine resources, ecological balance, and human food supply. At the same time, the preservation of cephalopod resources and the promotion of sustainable utilization also require attention. Many studies on the classification of cephalopods focus on the analysis of their beaks. In this study, we propose a feature fusion-based method for the identification of beaks, which uses the convolutional neural network (CNN) model as its basic architecture and a multi-class support vector machine (SVM) for classification. First, two local shallow features are extracted, namely the histogram of the orientation gradient (HOG) and the local binary pattern (LBP), and classified using SVM. Second, multiple CNN models were used for end-to-end learning to identify the beaks, and model performance was compared. Finally, the global deep features of beaks were extracted from the Resnet50 model, fused with the two local shallow features, and classified using SVM. The experimental results demonstrate that the feature fusion model can effectively fuse multiple features to recognize beaks and improve classification accuracy. Among them, the HOG+Resnet50 method has the highest accuracy in recognizing the upper and lower beaks, with 91.88% and 93.63%, respectively. Therefore, this new approach facilitated identification studies of cephalopod beaks

Identifying QTLs for Grain Size in a Colossal Grain Rice (<i>Oryza sativa</i> L.) Line, and Analysis of Additive Effects of QTLs

Grain size is an important component of quality and harvest traits in the field of rice breeding. Although numerous quantitative trait loci (QTLs) of grain size in rice have been reported, the molecular mechanisms of these QTLs remain poorly understood, and further research on QTL observation and candidate gene identification is warranted. In our research, we developed a suite of F2 intercross populations from a cross of 9311 and CG. These primary populations were used to map QTLs conferring grain size, evaluated across three environments, and then subjected to bulked-segregant analysis-seq (BSA-seq). In total, 4, 11, 12 and 14 QTLs for grain length (GL), grain width (GW), 1000-grain weight (TGW), and length/width ratio (LWR), respectively, were detected on the basis of a single-environment analysis. In particular, over 200 splicing-related sites were identified by whole-genome sequencing, including one splicing-site mutation with G>A at the beginning of intron 4 on Os03g0841800 (qGL3.3), producing a smaller open reading frame, without the third and fourth exons. A previous study revealed that the loss-of-function allele caused by this splicing site can negatively regulate rice grain length. Furthermore, qTGW2.1 and qGW2.3 were new QTLs for grain width. We used the near-isogenic lines (NILs) of these GW QTLs to study their genetic effects on individuals and pyramiding, and found that they have additive effects on GW. In summary, these discoveries provide a valuable genetic resource, which will facilitate further study of the genetic polymorphism of new rice varieties in rice breeding

Co-application of melatonin and zeolite boost bamboo tolerance under cadmium by enhancing antioxidant capacity, osmolyte accumulation, plant nutrient availability, and decreasing cadmium absorption

Bamboo, a fast-growing and high biomass plant, is one of the income resources of local people in the south and southeast of Asia, known as a food resource with high calories and fiber. However, increased heavy metal contamination cases in bamboo shoots have recently caused concerns. Recently, the role of zeolite and melatonin in the emendation of plant soil and increasing plant growth has been discovered, yet, there is no data on the combined effect of the two on bamboo species. The concurrent interaction in higher plants, particularly, remains elusive. Here, we investigated the role of a combination of zeolite and melatonin in bamboo under cadmium (Cd) stress. In one-year-old bamboo plants (Sasa kongosanensis f. aureo– striatusor), the treatments included a single 150 µM foliar spray of melatonin (Me) and 15 g Zeolite (Ze) kg−1 soil under four concentrations of Cd toxicity (0, 100, 150, and 200 mg L−1). The Cd-induced oxidative stress with overproduction of reactive oxygen species (ROS), lipoperoxidation, and membrane permeability imbalance in bamboo plants reduced biomass and growth. However, melatonin and zeolite alone and together significantly increased plant nutrients in the soil by enhancement of 23% in phosphorous, 23% in nitrogen, 20% in magnesium, 15% in calcium, 10% in potassium as well as 17% increase in relative water content (RWC), 7% in water content (WC), 16% in soluble carbohydrate, 34% in proline, 29% in antioxidant activity, and 26% in non-antioxidants, 13% in ascorbic acid, 24% in anthocyanin, 28% in chlorophylls, 14% in shoot, and 16% in root dry biomass and 15% in shoot length. We concluded that combining 150 µM melatonin and 15 g zeolite with essential mechanisms such as improving antioxidants, increasing plant nutrient availability, reducing Cd absorption, and raising osmolyte accumulation promotes bamboo durability against Cd toxicity and can help further reduce metal toxicity in bamboo species. Such an approach might subsequently have benefits for food safety
