This paper lists the recent developments in the FDS+Evac evacuation model. FDS+Evac is an agent based emergency egress simulation model which is embedded in the fire simulation program FDS, thus, enabling simultaneous simulation of the fire and egress processes. The main new feature of the evacuation module is better treatment of different behavioral types of the evacuees using herding type alg...

In current paper, we put forward a design method to Fault Diagnostic Systems(FDS) by proposing a new fault model and using the incremental hybrid learning algorithm which tightly combines symbolic learning and neural networks. It’s capable of overcoming several shortcomings in the existing diagnostic systems, such as the lack of universality, the unbalance in the use of fault prior knowledge an...

Disk scheduling is one of the main responsibilities of Operating System. OS manages hard disk to provide best access time. All major Disk scheduling algorithms incorporate seek time as the only factor for disk scheduling. The second factor rotational delay is ignored by the existing algorithms. This research paper considers both factors, Seek Time and Rotational Delay to schedule the disk. Our ...

Frame saw machine is one of tools that used to process dimension stone. The velocity fluctuation traditional feed drive system (FDS) lead excessive wear diamond particles. dynamic performance the FDS has time-varying characteristics during processing stone with a large material removal rate. In this paper, novel was proposed. Firstly, modeling set up on account lumped parameter method (LPM). Th...

Context. Galaxies either live in a cluster, group, or field environment. In the hierarchical framework, group environment bridges to cluster environment, as galaxies form groups before aggregating into clusters. principle, environmental mechanisms, such galaxy–galaxy interactions, can be more efficient than clusters due lower velocity dispersion, which lead changes properties of galaxies. This ...

Over the last twenty years, several algorithms have been proposed for automatic rule/constraint discovery from data, for the purpose of data cleaning. These algorithms look for constraints such as functional dependencies (FDs), conditional FDs (CFDs), inclusion dependencies (INDs), conditional INDs (CINDs), association rules, integrity constraints (ICs) and denial constraints (DCs), among other...

We present a complete logic for reasoning with functional dependencies (FDs) with semantics defined over classes of commutative integral partially ordered monoids and complete residuated lattices. The dependencies allow us to express stronger relationships between attribute values than the ordinary FDs. In our setting, the dependencies not only express that certain values are determined by othe...

The air fluorescence detectors (FDs) of the Telescope Array (TA) experiment have been constructed in a dessert of Utah, USA. We can measure the longitudinal developments of EASs directly with the FDs by detecting air fluorescence lights and determine the primary energies of ultra-high energy cosmic rays. In order for accurate observation and measurements of EASs, elaborate detector calibrations...
