Polymorphic Data Modeling
… on our new data modeling pattern named <em>The Polymorphic Table</em> <em>Pattern</em>. The pattern embraces the “schemaless” nature of document store NoSQL while allowing the data modeler to use his or her existing skillsets. The concepts of our proposed modeling have been demonstrated against …

Dinatural transformations and polymorphic operators
… context-free grammar, initial algebra, and polymorphic operator are elaborated. The theorem that the dinatural transformations between certain functors in the category of partial equivalence relations are exactly the canonical dinaturals is proved. Open questions are discussed, and …

Polymorphic computing abstraction for heterogeneous architectures
… is that application threads need to be polymorphic. Operating system layer is thus faced with the problem of scheduling polymorphic threads. Resource allocation is also an important problem to be dealt by the OS. Morphism evolution of application threads is constrained by the …

Conjunctive polymorphic type checking with explicit types
… type inference can be done for a large class of polymorphic functions, including those typeable with parametric types. To this end, we introduce a simple combinator based language with typing rules based on type conjunction and a subtype relation, of sorts, called "weaker." The validity of the …

DL-based defense against polymorphic network attacks
… when faced with continuously evolving atypical/polymorphic cyberattacks. Therefore, it is crucial to develop and train an AI-based Intrusion Detection System (IDS) that proactively learns to resist infiltration by such dynamically changing attacks. For this purpose, in this research work, we …

A polymorphic type system for logic programs
This thesis develops a polymorphic type system for logic programs. Our approach is semantically oriented. We define a type language with precise semantics. Type inference rules are derived from the semantics of the type language and the semantics of logic programs. Algorithms for automatic type …

Polymorphic Adversarial DDoS attack on IDS using GAN
… attackers look for new methods to evade the IDS. Polymorphic attacks are favorites among the attackers as they can bypass the IDS. GAN is a method proven in generating various forms of data. It is becoming popular among security researchers as it can produce indistinguishable data from the …

The bus structure for a polymorphic computer system
The proposed advances in fifth Generation Computing Systems aim to provide an Intelligent Image to the system user. While such images are software based, written in languages such as Prolog and LISP, much of the proposed hardware architecture has lacked innovation and vision. This Thesis addresses …

Evolutionary polymorphic neural networks in chemical engineering modeling
Evolutionary Polymorphic Neural Network (EPNN) is a novel approach to modeling chemical, biochemical and physical processes. This approach has its basis in modern artificial intelligence, especially neural networks and evolutionary computing. EPNN can perform networked symbolic regressions for …

Investigations of polymorphic colour vision in new world primates
… for maintaining colour vision polymorphism. For polymorphic colour vision to be complementary advantageous, primates should be able to perceive the behavioural changes resulting from sensory abilities of conspecifics. Cooperation tests were used with captive primates to investigate the …

Bio-inspired lightweight polymorphic security system for IoT devices
… This thesis proposes a novel application of polymorphic principles, inspired by biological immune systems, to engineer a lightweight, adaptive, and resilient security system for resource-constrained Internet of Things (IoT) devices. The Bio-Inspired Lightweight Polymorphic Security System …

The Conformational Dynamics of the Polymorphic Amyloid β Protofilaments
… the Aβ protofilament. Therefore, we studied two polymorphic Aβ (9-40) structures [1] as likely conformations. We relaxed the structures through normal mode analysis. In normal mode analysis, we approximated around a thermal equilibrium and treated every atom-to-atom interaction like a …

Random amplified polymorphic DNA (RAPD) analysis of Bacillus sphaericus
… and phage typing. I have used random amplified polymorphic DNA (RAPD) fingerprinting to determine the phenetic relationships among 31 pathogenic and 14 nonpathogenic strains of B. sphaericus. DNA Bands in agarose gel migrating the same distance were verified as being homologous using …

Polymorphic mating signals and female choice in an Amazonian frog
… observations to understand the evolution of polymorphic male mating signals in the frog Peters’ Dwarf Frogs (Physalaemus petersi). In this frog, different populations form distinct genetic clades that coincide with the type of advertisement call males produce. My thesis has four chapters: the …

Polymorphic types for constructing concurrent objects and layered communication protocols
Polymorphic type abstractions are proposed for constructing concurrent objects and layered peer-to-peer communication protocols, both of which exhibit inherently asynchronous behavior. The type abstractions are shown to be both expressive and efficient in the context of a statically typed …

Exploration of High-Pressure Electride, Polymorphic Transformations, and Superconducting Clathrate Frameworks
The exponential growth of high-performance computing resources has transformed first-principles modeling into a cornerstone of condensed matter research. Today, large-scale density-functional theory calculations, accelerated by machine-learned interatomic potentials and high-throughput workflows, …

Insertionally polymorphic human endogenous retroviruses and their potential role in cancer
… with some of its members being insertionally polymorphic in modern human populations. There have been numerous reports of HERV-K(HML-2) members being present in cancer samples. Here, a robust analysis of the state of HERV-K(HML-2) family in the human genome known to date is presented, along …
