In this paper, we introduce a cerebral cortex inspired architecture for robots in which we have mapped hierarchical cortical representation of human brain to logic flow and decision making process. Our work focuses on the two major features of human cognitive process, viz. the perception-action cycle and its hierarchical organization, and the decision making process. To prove the effectiveness ...

To provide hierarchical description from different software architectural viewpoints we need more than one abstraction hierarchy and connection mechanisms to support the interactions among components. Also, these mechanisms will support the refinement and traceability of architectural elements through the different levels of each hierarchy. Current methods and tools provide poor support for the...

Hierarchical Mobile IPv6 (HMIPv6) is an enhanced Mobile IPv6 for reducing signaling cost of location management. Multi-level Hierarchical Mobile IPv6 (MHMIPv6) can organize mobile region as a multi-level hierarchy architecture, which is more flexible to support scalable services. However, MHMIPv6 will bring additional packet processing overhead, and produce negative impact especially on some mo...

Course generation automatically assembles courseware adapted to the learner’s competencies and learning goals. Previous course generators offered only a limited representation a pedagogical knowledge and did not take full advantage of service-oriented architectures. This dissertation proposes a course generation framework (called Paigos) that enables the formalization and application of complex...

In this report, we develop a railway control system. We are mainly concerned with the software architecture of the control system and its dynamic evolution; we do not discuss here the implementation details of the components forming the control system. The software architecture is characterized by a hierarchy of controllers whose leaves are local controllers connected in a network that mimics t...

In this paper, by introducing hierarchical component model into design of ATP (Auto Train Protection) software architecture, an applicable railway signal system software modeling scheme is proposed. For detail discussion, the design of software hierarchical architecture, hierarchical component model, dynamic component insert mechanism and fault injection mechanism have been also presented. As r...

A hierarchical MEMS synthesis and optimization architecture has been developed for MEMS design automation. The architecture integrates an object-oriented component library with a MEMS simulation tool and two levels of optimization: global genetic algorithms and local gradient-based refinement. An object-oriented data structure is used to represent hierarchical levels of elements in the design l...

Image location prediction is to estimate the geolocation where an image is taken. Social image contains heterogeneous contents, which makes image location prediction nontrivial. Moreover, it is observed that image content patterns and location preferences correlate hierarchically. Traditional image location prediction methods mainly adopt a single-level architecture, which is not directly adapt...

Building robust and reliable storage systems and memory hierarchies is very important in modern computing environment because hierarchical memory architecture is present almost everywhere. This hierarchy is not limited to attached devices, but it expands to middle-tiers, web caches, and network and internet storage. So optimizing access of the data stored along all these hierarchical levels is ...
