This paper investigates updates of Universal Dependencies (UD) treebanks in 23 languages and their impact on a downstream application. Numerous people are involved in updating UD's annotation guidelines and treebanks in various languages. However, it
is not easy to verify whether the updated resources maintain universality with other language resources. Thus, validity and consistency of multilingual corpora should be tested through application tasks involving syntactic structures with PoS tags, dependency labels, and universal features. We apply the syntactic parsers trained on UD treebanks from multiple versions (2.0 to 2.7) to a clause-level sentiment extractor. We then analyze the relationships between attachment scores of dependency parsers and performance in application tasks. For future UD developments, we show examples of outputs that differ depending on version.
Building Information Modeling (BIM) has been one of the most significant developments
in the construction industry in the last decade. BIM has been used in various stages of
construction, including maintenance and operation of facilities. BIM has a
ssisted the
management of the facility to deal with a large amount of maintenance information
including drawings, specifications. BIM has proven its effectiveness as a repository for
various types of data in building maintenance and a tool to support decision-making in the
field of maintenance.
However, the optimum maintenance of the facility is not only based on quantitative data,
but also on the knowledge and experience acquired by the company and the workers.
These experiences may be lost forever if they are not documented due to resignation and
retirement.
In this research we provide a methodology for obtaining knowledge while performing
maintenance of public buildings using BIM and Dynamo application using Parametric
models, which provide us with a high-central framework for information storage and
Visual Programming, which provides great capabilities for processing and extracting data
from a model BIM, processed, categorized into design, implementation and operational
knowledge, exported and re-linked to the building elements of the BIM model, up to a
BIM-oriented maintenance model with all design knowledge and addressed to the design
authorities.
The research focuses on finding planning methods based on measuring and monitoring the
basic indicators of internal combustion engines (Diesel engines) in order to determine the
critical case of the engines, which determines the expected time for t
he engine or for some
of its basic parts to be sent for comprehensive maintenance.
The wear ratio of one of the basic components of the engine was also determined, we also
chose the diameter of the cylinder and the corrosion that happens to it in order to
determine the engine's lifetime and determine the moment when the engine should be sent
for comprehensive maintenance.
By observing a large number of engines put in repair in the industrial area in Lattakia,
which are 30 engines of different types of diesel and gasoline, and with different
capacities, it was noticed that about 15% of these engines were not exploited and invested
the entire work period designed for them. Also it was noticed that 20% of them have
stopped working because of the severe corrosion of parts, components and mechanics of
these engines, which led to their damage and their inability to do their work on a regular
basis. This has contributed to increased consumption of fuel and Lubricating materials,
which causes damage to the national economy.
The proposed planning method for determining the critical case of the engine when
comparing the schematic results with the practical results of the engines has proved its
efficiency and accuracy with an error rate of no more than 6% This allows it to be applied
and adopted as an effective way to determine the actual lifetime of the engine and compare
it with the life time of investing the engine mentioned in the manufacturer's catalogs when
operating the engine under normal conditions.
Maintenance in water structures is defined as a specific pre-planned execution, carried out
at the specified time, which leads to the permanence of these water structures, and their
continued functioning with economic and effective benefits. Water
structures of various
types and during normal use require care and maintenance in the required form, and at the
appropriate times, to have a permanent readiness, and to maintain the correct state, in
addition to prolonging their life. Therefore, periodic maintenance of the water structures is
of great importance due to its economic implications.
The aim of this research is to highlight the importance of regular and integrated
maintenance of water structures, to achieve optimum economic investment, and to study
the possibility of applying maintenance works to the faults of various water structures. It
also displays different types of maintenance and their applicability to these structures.
Finally, it provides an overview of the guidelines and recommendations for the safety of
these water structures, and the safety of personnel working in this engineering field.
Rural areas form a large part of Syria's coastal area. Linking between these areas and city
centers transact of a network of roads. Each of these roads and transport means form the
rural transport system which characterized by general characteristi
cs of low levels of
traffic, economic activity and population density, and long distances between centers such
as service centers. The presenting of services, operations and maintenance characterize at
high costs, and there are often difficult geographical and natural conditions.
Vehicle operating costs refer to costs that vary with vehicle usage, including fuel, tires,
maintenance, repairs…etc., which dependent on the mileage.
Transportation agencies and maintenance workshops were visited during this study. As
well as, interviews have been done with a random sample of public transport drivers
working on some rural axes in the coastal area, in order to obtain the required information
about the vehicle operating and maintenance costs.
The study concluded by identifying the most important factors that may effect on the tariff
of passenger transport on rural axes (maintenance of the vehicle, fuel costs, quality of the
road .....) and proposing a number of recommendations aimed at improving the public
transport system and raising its efficiency in rural areas.
This study shows the application of network planning tool for planning, scheduling
and control of maintenance operations. Taking into account that the maintenance process is
a project as it consists of a set of actions that consume specific resourc
es and have a data
specified achievement. Thus you can create a represents the maintenance process activities.
This diagram helps to maintenance process scheduling, additionally, it allows activity time
maintenance. For this purpose, we used the project. Evaluating and Review technique,
because it respond to order delivery vacillation.
Total productive maintenance (TPM) for the time being is of great
importance in Investment Projects, for the need to preserve the
physical assets and continuity of work.
In this research study
the possibility of thermal energy lost investment with all of the
cooling water and oil in the Czech locomotive engine LDE1500 in circuit

The importance of this research lies in establishing an integrated system to support
decision making of bituminous road surface maintenance in Lattakia within the
environment of Geographic Information Systems, which leads to improve the level of
p
erformance and reach better conditions of road safety and comfort.
In a former research, the bituminous surface condition data was conducted and filled
in the Asphalt Institute Form by which we obtained an overall condition rating that led in
turn to the type of maintenance of each studied segment and link them to the digitized
maps where every segment appeared in a color reflecting its condition according to the
purpose of the map.
In this research we depended on the " Project Priority Methodology " to view and
query different alternatives to support decision making of which road segments should be
maintained first by using five categories each one gives us a weighing value, then we
collected the total weighed value for the five categories together, and link that to digitized
maps that guaranteed fast and direct reach to various solutions to choose the best, insuring
as a result that the traditional way in maintenance which begins with the worst segment is
not always the best, and that its time to move towards new pavement maintenance
management systems.
School buildings in Syria suffer of the high cost of maintenance works. In addition,
there is no fear methodology to organize the maintenance process and evaluate the
performance of these buildings.
This research aims to develop a system for evalu
ating the performance of school
buildings in the city of Tartous, in order to be used in the maintenance policy for these
buildings and other buildings in other regions.
The evaluating process is executed by calculating a performance indicator, which
defines the state of the building depending on three sub-indicators: functional, technical
and healthiness indicator.
Maintenance manual and evaluating lists were developed to evaluate the components
of school building. In addition, many questionnaires were set to determine the relative
importance for each component of school building.
The improved model was used to calculate the performance indicators for several
schools. As a result, most of these schools were in a moderate situation. Also, the results
clarify that some components have law state comparing to other ones and we should focus
on them in organized maintenance processes.
