-Organizations need to work on productivity improvement in order to enhance their operational performances. A number of works have taken efforts in efficiency evaluation and ranking using analytic methods such as the data envelopment analysis (DEA). However, few works have highlighted the relationship among significant factors that affect productivity. Performing efficiency evaluation and ranki...

Over the course of the past half a century, a vast amount of research has been undertaken on the welfare state comprising a wide range of theoretical perspectives and empirical traditions. However, exactly how such plurality should be regarded has been less than clear since there has notably been a lack of discourse within the field of comparative political economy with regard to possible ways ...

A path-factor in a graph G is spanning subgraph F of such that every component path. Let d and n be two nonnegative integers with ≥ 2. P -factor its each whose components path at least vertices. called covered if for any e ∈ E ( ), admits containing . , )-factor critical N ⊆ V ) | = the − graph. uniform In this paper, we verify following results: (i) An + 1)-connected order 3 ≥3 satisfies δ &gt...

the chamomile species of anthemis triumfettii (l.) all is one of important medicinal plant belong to compositae family and it grows as wild species in zagros and alborz mountains, iran. the aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. seeds of seven accessions were sown in jiffy pots and transferred to field using rando...

In this dissertation the work done in the projects KME-410/502 will be presented. The overall objective in these projects is to evaluate and develop tools for designing against fatigue in single-crystal nickel-base superalloys in gas turbines. Experiments have been done on single-crystal nickel-base superalloy specimens in order to investigate the mechanical and fatigue behaviour of the materia...

Although many performance studies of memory speculation mechanisms in speculative multithreading chip multiprocessors have been reported, it is still questionable whether the mechanisms are complexity effective and worth to implement. In this paper, we perform a complexity analysis of a cache controller designed by extending an MSI controller to support thread-level memory speculation. We model...

We present experimental results on the use of antifuse-based FPGA's in a performance critical digital design, performed at the recently completed Thayer Rapid Prototyping Facility. Our case study focuses on the design of a special purpose ALU for gene sequence analysis. Our work indicates the existence of highly nonlinear relationships between design changes and critical path lengths, due to th...

Efficient performance tuning of parallel programs is often hard. Optimization is often done when the program is written as a last effort to increase the performance. With sequential programs each (executed) code segment will affect the completion time. In the case of a parallel program executed on a multiprocessor this is not always true, due to dependencies between the different threads. Thus,...

In Wireless Sensor Networks, data collection by the Mobile Sink (MS) from the sensor nodes is a challenging task. In the proposed approach, the MS visits an optimal set of subsinks in order to collect data instead of visiting all the nodes in the network. In this paper, the subsink selection has been proven to be optimal since the subsinks are chosen by the Critical Path Method (CPM). Initially...

In this paper, a new very fast fault simulation method to handle the X-fault model is proposed. The method is based on a two-phase procedure. In the first phase, a parallel exact critical path fault tracing is used to determine all the detected stuck-at faults in the circuit, and in the second phase a postprocess is launched which will determine the detectability of X-faults. Keywords-digital c...
