We have proposed, fabricated and demonstrated experimentally a set of Coherent Direct Sequence-OCDMA en/decoders based on Super Structured Fiber Bragg Gratings (SSFBGs) which are able to compensate the fiber chromatic dispersion at the same time that they perform the en/decoding task. The proposed devices avoid the use of additional dispersion compensation stages reducing system complexity and ...

We implement and prove correct 2-3 finger trees. Finger trees are a general purpose data structure, that can be used to efficiently implement other data structures, such as priority queues. Intuitively, a finger tree is an annotated sequence, where the annotations are elements of a monoid. Apart from operations to access the ends of the sequence, the main operation is to split the sequence at t...

introduction & objective: adequate and proper hydration during surgery is one of the duties of anesthesiologist. based on the different effects of dextrose–containing fluids and dextrose-free fluids on the level of blood sugar, we decided to evaluate the effects of these fluids on the blood sugar level after short-term surgeries. materials & methods: one hundred patients who were scheduled for ...

distance-balanced graphs are introduced as graphs in which every edge uv has the followingproperty: the number of vertices closer to u than to v is equal to the number of vertices closerto v than to u. basic properties of these graphs are obtained. in this paper, we study theconditions under which some graph operations produce a distance-balanced graph.

The paper describes an intelligent ant system-based algorithm for automatic generation of optimal sequence of machining operations required to produce a part, based on minimising the number of tool changes and set-up changes subject to satisfying all precedence constraints during manufacturing. The MATLAB programme for the algorithm uses a list of machining operations, tool approach directions,...

In this article, we present a novel machine translation model, the Operation Sequence Model (OSM), that combines the benefits of phrase-based and N-gram-based SMT and remedies their drawbacks. The model represents the translation process as a linear sequence of operations. The sequence includes not only translation operations but also reordering operations. As in Ngram-based SMT, the model is: ...

Many algorithms amount to a sequence of operations on a data structure. For instance, the well-known heapsort algorithm is a sequence of insert’s into an initially empty priority queue, followed by a sequence of deleteMin’s from the queue until it is empty. Thus if ci is the cost of the ith operation, the algorithm’s running time is ∑2n i=1 ci, since there are 2n operations for sorting n elemen...

A dynamic algorithm was characterized by the concept of an “on-line” sequence of operations on a data structure. These operations being query and update. Each operation may be performed before the next operation is known. For example, if you had a directed graph, an intermixing of updates and queries to this graph can be made. A query might be: is there a directed path between two nodes of the ...

very little is known about lhr and fshr genes of domestic dromedary camels. the main objective of this study was to determine and analyze partial genomic regions of fshr and lhr genes in dromedary camels for the first time. to this end, a total of 50 dna samples belonging to dromedary camels raised in iran were sent for sequencing (25 samples of each gene). we compared the nucleotide sequences ...

This article presents a control scheme in the stationary reference frame for static synchronous compensators (STATCOMs) that provide three features: 1) regulation of positive-sequence voltage to nominal value; 2) full cancellation negative-sequence voltage; and 3) peak limitation injected currents. These features can help improve performance these devices under perturbed grid conditions, includ...
