Book Description
Morphological, biological, biochemical and physiological characteristics have been used for the detection, identification and differentiation of fungal pathogens up to species level. Tests based on biological characteristics are less consistent. Immunoassays have been shown to be effective in detecting fungal pathogens present in plants and environmental samples. Development of monoclonal antibody technology has greatly enhanced the sensitivity and specificity of detection, identification and differentiation of fungal species and varieties/strains. Nucleic acid-based techniques involving hybridization with or amplification of unique DNA have provided results rapidly and reliably. Presentation of a large number of protocols is a unique feature of this volume.

Book Description
Comprehensive global garbage detection (GGD) in object-oriented distributed systems, i.e., GGD intrinsically able to detect distributed cycles of garbage, has mostly been addressed via graph tracing algorithms. Graph tracing algorithms must account for every live object in the system before any resource can actually be reclaimed which compromises both their scalability and robustness in a distributed environment. Alternative non-comprehensive approaches trade-off comprehensiveness for scalability and robustness under the assumptions that distributed cycles of garbage are rare and that all comprehensive algorithms are necessarily unscalable. This thesis contends instead that distributed cycles of garbage are as likely to occur as local cycles and that a comprehensive alternative to graph tracing GGD is possible. From the GGD perspective, the combined effects of the application processes and local garbage collectors fulfill the role of a global mutator. A subset of events of this global mutator's computation, called log-keeping events, reflect either the creation, or the destruction, of inter-site paths in the global object graph. The causal history of a log-keeping event corresponds to the set of events responsible for the creation of all the paths ever created that are incident to an object. The path history of this event is defined as a subset of its causal history and contains only those events responsible for the creation of the extant paths to this object. This dissertation presents a novel approach to comprehensive GGD that entails computing dependency vectors which characterize the path history of log-keeping events that reflect the destruction of a path. These dependency vectors can be computed by propagating increasingly accurate approximations of these vectors along the paths of the global object graph. In effect, this algorithm reacts to events that may result in the creation of garbage and identifies garbage without requiring a complete scan of the whole object graph. In conjunction with a lazy log-keeping mechanism, it can therefore be shown to be both scalable and robust despite being comprehensive.

Book Description
Open world games have tremendously become a demanding criterion for computer games development as user be able to freely roam through land and sea virtually. One of the elements involving computer games development is to bring applicable real-time collision detection for each object. Collision detection required sophisticated process of using hierarchical approach of Bounding-Volume Hierarchies (BVH) for detecting procedure. BVH is one of the most challenging issues in collision detection area that critically undergoing multiple splitting process. Splitting process requires an object with their set of triangles to be split into two parts using binary type tree. It is very crucial to make sure that the BVH tree construction is always in balanced as the speed of BVH tree traversal algorithm is dropped for unbalanced tree. In this thesis, we introduced Spatial Object Median Splitting (SOMS) to enhance the capability of BVH construction. Hence, SOMS creates an optimum level of BVH where most leaf nodes that was bounded with AABB contained one triangle compared to Spatial Median technique. From the BVH construction experiments, SOMS managed to perform faster as compared to other common technique. Furthermore, experiment to create one BV one triangle also showed that SOMS produced more nodes. As a conclusion, BVH can easily be constructed using SOMS approach together to create higher level of balanced tree for collision detection.

Book Description
The global population is increasing rapidly, and feeding the ever-increasing population poses a serious challenge for agriculturalists around the world. Seed is a basic and critical input in agriculture to ensure global food security. Roughly 90 percent of the crops grown all over the world are propagated by seed. However, seed can also harbour and spread pathogens, e.g. fungi, bacteria, nematodes, viruses etc., which cause devastating diseases. Seed-borne pathogens represent a major threat to crop establishment and yield. Hence, timely detection and diagnosis is a prerequisite for their effective management. The book "Seed-Borne Diseases of Agricultural Crops: Detection, Diagnosis & Management" addresses key issues related to seed-borne/transmitted diseases in various agricultural crops. Divided into 30 chapters, it offers a comprehensive compilation of papers concerning: the history of seed pathology, importance of seed-borne diseases, seed-borne diseases and quarantine, seed health testing and certification, detection and diagnosis of seed-borne diseases and their phytopathogens, host-parasite interactions during development of seed-borne diseases, diversity of seed-borne pathogens, seed-borne diseases in major agricultural crops, non-parasitic seed disorders, mechanisms of seed transmission and seed infection, storage fungi and mycotoxins, impact of seed-borne diseases on human and animal health, and management options for seed-borne diseases. We wish to thank all of the eminent researchers who contributed valuable chapters to our book, which will be immensely useful for students, researchers, academics, and all those involved in various agro-industries.
