The physics motivations for a fine grain 1st level electron/photon trigger which exploits the properties of the CMS crystal calorimeter are briefly introduced. An implementation architecture that extends the present design of the CMS calorimeter trigger is described. We then discuss the characteristics and the requirements of the electronic circuits needed to implement the fine grained trigger ...

To assign semantic roles in building Treebanks, there is a need for annotators having a guideline in determining semantic relations between phrasal head and its modifiers or arguments. Semantic roles are hard to have clear-cut definitions. It is not always easy to determine thematic relations between two concepts. This paper aims to introduce an integrated nominal modifier system. Basically we ...

We describe an implementation of a fine-grain adaptive scheduling mechanism, based on software feedback. Conventional scheduling makes job assignment exclusively a function of time. We broaden the meaning of the term "scheduling" to include job assignment as a function of a sequence of events, such as timer interrupts, I/O operations, queue overflodunderflow, and system call traps. Our implemen...

This paper proposes a benchmarking methodology for characterising the power consumption of the fine-grain fabric in reconfigurable architectures. This methodology is part of the GroundHog 2009 power benchmarking suite. It covers active and inactive power as well as advanced low-power modes. A method based on random number generators is adopted for comparing activity modes. We illustrate our app...

This paper presents a new scheme to replace course grain barriers with ne grain synchronisation in virtual shared memory systems. Traditionally, shared memory programming models separate data access from synchronisation. In our scheme synchronisation between both writes and their subsequent reads, and reads and their following writes, is achieved through the coherence tags associated with each ...

This work has two primary goals. The first is to advance our fundamental understanding of grain boundaries by making direct measurements of grain boundary thermodynamic properties using ultrafine-grained materials. The second is to explore possible deviations from conventional behavior at ultrafine grain sizes, specifically in regards to grain boundary thermodynamic properties and solute segreg...

This study explores incremental processing in spoken word recognition in Russian 5- and 6-year-olds and adults using free-viewing eye-tracking. Participants viewed scenes containing pictures of four familiar objects and clicked on a target embedded in a spoken instruction. In the cohort condition, two object names shared identical three-phoneme onsets. In the noncohort condition, all object nam...

Multi-core architectures are becoming mainstream, permitting increasing on-chip parallelism through hardware support for multithreading. Synchronization, especial finegrain synchronization, is essential to the effective utilization of the computational power of high-performance large-scale multi-core architectures. However, designing and implementing fine-grain synchronization in such architect...

A safe basis for automatic loop parallelization is the polyhedron model which represents the iteration domain of a loop nest as a polyhedron in Zn. However, turning the parallel loop program in the model to efficient code meets with several obstacles, due to which performance may deteriorate seriously – especially on distributed memory architectures. We introduce a fine-grained model of the com...
