This research includes a geodetic study for the rehabilitation of damaged bridge cranes axes, its reconstruction and calibration in order to invest in the production process. The beginning was devoted to studying the types of bridge cranes used in large factories, geodetic methods used in their construction, and the conditions that must be achieved by axes. Based on the previous conditions, we have proposed a geodetic method to rehabilitate cranes. Also, a computer program has been prepared to implement the proposed mechanism by (mat lab). Testing the proposed method I has been done with the program on actual examples. The program was tested in two main cases: -First: When installing bridge cranes axes, -Second: In the periodic monitoring (systematic control) for bridge cranes. The research has proved the possibility of using the proposed method in rehabilitation, installation, periodic monitoring. It also has showed the efficiency of the proposed computer program.

Historical linguists have identified regularities in the process of historic sound change. The comparative method utilizes those regularities to reconstruct proto-words based on observed forms in daughter languages. Can this process be efficiently au
tomated? We address the task of proto-word reconstruction, in which the model is exposed to cognates in contemporary daughter languages, and has to predict the proto word in the ancestor language. We provide a novel dataset for this task, encompassing over 8,000 comparative entries, and show that neural sequence models outperform conventional methods applied to this task so far. Error analysis reveals a variability in the ability of neural model to capture different phonological changes, correlating with the complexity of the changes. Analysis of learned embeddings reveals the models learn phonologically meaningful generalizations, corresponding to well-attested phonological shifts documented by historical linguistics.
We propose a deep generative model that performs typography analysis and font reconstruction by learning disentangled manifolds of both font style and character shape. Our approach enables us to massively scale up the number of character types we can
effectively model compared to previous methods. Specifically, we infer separate latent variables representing character and font via a pair of inference networks which take as input sets of glyphs that either all share a character type, or belong to the same font. This design allows our model to generalize to characters that were not observed during training time, an important task in light of the relative sparsity of most fonts. We also put forward a new loss, adapted from prior work that measures likelihood using an adaptive distribution in a projected space, resulting in more natural images without requiring a discriminator. We evaluate on the task of font reconstruction over various datasets representing character types of many languages, and compare favorably to modern style transfer systems according to both automatic and manually-evaluated metrics.
We propose a multi-task, probabilistic approach to facilitate distantly supervised relation extraction by bringing closer the representations of sentences that contain the same Knowledge Base pairs. To achieve this, we bias the latent space of senten
ces via a Variational Autoencoder (VAE) that is trained jointly with a relation classifier. The latent code guides the pair representations and influences sentence reconstruction. Experimental results on two datasets created via distant supervision indicate that multi-task learning results in performance benefits. Additional exploration of employing Knowledge Base priors into theVAE reveals that the sentence space can be shifted towards that of the Knowledge Base, offering interpretability and further improving results.
The transport sector provides suitable and appropriate conditions for the development of
the various sectors of the national economy, productivity and other services. Its
relationship with these sectors is characterized by a mutual influence relati
onship, which
means that no progress or development can be achieved in any of these sectors without
preceded or accompanied by significant progress in the transport sector.
The government has given special importance to this division since the inception of
independence, when the sector was allocated large provision in its successive five-year
plans. After the year 2000, there was a big leap in the provision of the allocations assigned
to the transport sector, where reached (to the ninth five-year plan (2001-2005)) the
equivalent to the expenditure on this sector in the previous five-year plans combined.
The systematic destruction and devastation of the crisis in Syria since March 2011 aimed at
splitting the country and paralyzing the traffic of passengers and goods. As a result, the
transport sector suffered heavy economic losses in its infrastructure and transportation.
These losses were evaluated in this research for the years 2011-2012, 2013 and the state of
the transport sector was reviewed before the crisis.
In view of the importance of this sector and its key role in the reconstruction, there was a
package of proposals and visions that were put forward for the reconstruction of the
infrastructure of the sector itself as a priority and strengthening the role of this sector in the
reconstruction and development within the framework of comprehensive regional planning
and sustainable development.
Perhaps the most important impact of the crisis was the decision of the Syrian state oriental
direction in its policy, which directly affects the implementation of transport networks and
infrastructure and means of transport.
Based on the goal of linking the five seas, which have set a higher goal in the national
framework for regional planning, some visions have been reviewed that can achieve this
goal in order to attract international transport and transit through Syria and exploit its
geographical position as a transport hub leading to an increase in economic growth rate To
raise the contribution of the transport sector to GDP.
In this paper, an iterative numerical method for obtaining approximate values of
definite single, double and triple integrals will be illustrated. This method depends on
approximating the single integral function by spline polynomial of fifth degre
e, while
Gauss Legendre points as well as spline polynomials are used for finding multiple
integrals.
The study shows that when the method are applied to single integrals is convergent
of order sixth, as well as when applied to triple integrals is convergent of order sixth for
three Gauss Legendre points or greater.
Errors estimates of the proposed method alongside numerical examples are given to
test the convergence and accuracy of the method.
