Application of a Generic Curriculum Change Management Process to Motivate and Excite Students

The School of Mechanical and Aerospace Engineering at Queen’s University Belfast is committed to enhancing the quality of student learning. A plan to implement curriculum change around this goal has been formulated and is already several years underway. A specific part of the plan involved instigating a first year introductory module to engage the students in the practice of their engineering discipline. The complicated nature of devising this type of module with regard to objectives, resources, timeframe and the number of students involved meant that a very systematic approach had to be adopted. This paper presents the simple but definitive change management process that facilitated in the creation of a first year Introduction to Engineering module. The generic nature of this process is described and its application to other facets of curriculum change is discussed. Within this process the importance of collaboration to establish a forward momentum is emphasised. This enables academic staff to progress as a group and build curriculum development based on their own experiences, expertise and established practice

Comparison of a centralised and distributed approach for a generic scheduling system

PEGS (Production and Environmental Generic Scheduler) is a generic production scheduler that produces good schedules over a wide range of problems. It is centralised, using search strategies with the Shifting Bottleneck algorithm. We have also developed an alternative distributed approach using software agents. In some cases this reduces run times by a factor of 10 or more. In most cases, the agent-based program also produces good solutions for published benchmark data, and the short run times make our program useful for a large range of problems. Test results show that the agents can produce schedules comparable to the best found so far for some benchmark datasets and actually better schedules than PEGS on our own random datasets. The flexibility that agents can provide for today's dynamic scheduling is also appealing. We suggest that in this sort of generic or commercial system, the agent-based approach is a good alternative.

Japan’s Blair Witch: Restraint, Maturity, and Generic Canons in the British Critical Reception of Ring

This essay examines the British critical reception of the Japanese horror ? lm Ring. Critics claimed that Ring was representative of a non-graphic, suggestive tradition in horror, and used the ?lm rhetorically to present a sense of difference from teen horror ?lms such as Scream.

RESURRECTION OF THE GENUS OSMUNDEA WITH AN EMENDATION OF THE GENERIC DELINEATION OF LAURENCIA (CERAMIALES, RHODOPHYTA)

Vegetative and reproductive development of some European and Californian species of Laurencia Lamouroux (Ceramiales, Rhodophyta), L. obtusa (Hudson) Lamouroux, L. spectabilis Postels et Ruprecht, L. crispa Hollenberg, L. osmunda (S.G. Gmelin) Maggs et Hommersand, L. pinnatifida (Hudson) Lamouroux and L. truncata Kutzing, is investigated on the basis of liquid-preserved and herbarium specimens. The latter five species share several features, but they differ distinctly from L. obtusa, the lectotype of the genus, in essential anatomical characters of vegetative and male reproductive structures and tetrasporangial development. In these five species each vegetative axial segment produces two rather than four pericentral cells, and spermatangial branches (filaments) are produced in apical pits of branchlets from apical and epidermal cells rather than from trichoblasts arising from axial cells. The spermatangial branches are usually branched alternately and usually terminate in a cluster of several large sterile vesicular cells, rather than being branched dichotomously and terminating in a single, or occasionally a row of two, large sterile vesicular cells as in L. obtusa. Apical spermatangial pits of fertile male branchlets (except for those in L. truncata) are pocket- (or urn)-shaped, with an ostiole-like upper opening, rather than cup- (or bowl)-shaped. In these five species tetrasporangia are produced laterally from random epidermal cells rather than abaxially from particular pericentral cells (the third and fourth ones) as in L. obtusa, and the two presporangial cover cells are aligned parallel rather than transverse to the stichidial axis in surface view. These important differences strongly suggest that L. spectabilis, L. crispa, L. osmunda, L. pinnatifida and L. truncata occupy a phylogenetically different position from L. obtusa, and lead to the conclusion that the genus Osmundea Stackhouse, which was based on 0. expansa Stackhouse, nom. illeg. (= Laurencia osmunda) and which has been a nomen rejiciendum as an earlier facultative synonym of Laurencia, should be resurrected. Emendations of the generic criteria of Laurencia and Osmundea are proposed here, and relevant nomenclatural changes for several Laurencia species are also included.

Generic scheduling methods for a linear QR array SoC processor

A scheduling method for implementing a generic linear QR array processor architecture is presented. This improves on previous work. It also considerably simplifies the derivation of schedules for a folded linear system, where detailed account has to be taken of processor cell latency. The architecture and scheduling derived provide the basis of a generator for the rapid design of System-on-a-Chip (SoC) cores for QR decomposition.

A Generic Reference Software Architecture for Load Balancing over Mirrored Web Servers: NaSr Case Study

With the rapid expansion of the internet and the increasing demand on Web servers, many techniques were developed to overcome the servers' hardware performance limitation. Mirrored Web Servers is one of the techniques used where a number of servers carrying the same "mirrored" set of services are deployed. Client access requests are then distributed over the set of mirrored servers to even up the load. In this paper we present a generic reference software architecture for load balancing over mirrored web servers. The architecture was designed adopting the latest NaSr architectural style [1] and described using the ADLARS [2] architecture description language. With minimal effort, different tailored product architectures can be generated from the reference architecture to serve different network protocols and server operating systems. An example product system is described and a sample Java implementation is presented.

Generic low-latency NoC router architecture for FPGA computing systems

A novel cost-effective and low-latency wormhole router for packet-switched NoC designs, tailored for FPGA, is presented. This has been designed to be scalable at system level to fully exploit the characteristics and constraints of FPGA based systems, rather than custom ASIC technology. A key feature is that it achieves a low packet propagation latency of only two cycles per hop including both router pipeline delay and link traversal delay - a significant enhancement over existing FPGA designs - whilst being very competitive in terms of performance and hardware complexity. It can also be configured in various network topologies including 1-D, 2-D, and 3-D. Detailed design-space exploration has been carried for a range of scaling parameters, with the results of various design trade-offs being presented and discussed. By taking advantage of abundant buildin reconfigurable logic and routing resources, we have been able to create a new scalable on-chip FPGA based router that exhibits high dimensionality and connectivity. The architecture proposed can be easily migrated across many FPGA families to provide flexible, robust and cost-effective NoC solutions suitable for the implementation of high-performance FPGA computing systems. © 2011 IEEE.
