Solving Aspect Category Sentiment Analysis as a Text Generation Task

Aspect category sentiment analysis has attracted increasing research attention. The dominant methods make use of pre-trained language models by learning effective aspect category-specific representations, and adding specific output layers to its pre-trained representation. We consider a more direct way of making use of pre-trained language models, by casting the ACSA tasks into natural language generation tasks, using natural language sentences to represent the output. Our method allows more direct use of pre-trained knowledge in seq2seq language models by directly following the task setting during pre-training. Experiments on several benchmarks show that our method gives the best reported results, having large advantages in few-shot and zero-shot settings.

Studying the effect of some environmental factors on the phenolic content of Rhus cotinus L. (Jableh area)

This study aimed at investigating the effect of some environmental factors on the phenolic contents of the Rhus cotinus L. plant. Plant samples (leaves, flowers and bark) were collected from three aspects (south, west and north) at four altitudes (0-300, 300-600, 600- 900, ˃900m) in the countryside of Jableh in 2016. The fresh samples were extracted using 95% ethanol as an extraction solution, then the total contents of the phenolic compounds were determined spectrophotometrically using the Folin-Ciocalteu reagent, expressing the result by (mg gallic acid/1g fw) using a Spectrophotometer.

Building And Evaluating Digital Elevation Models (Dem) Byusing Geographic Information System

This research aimed for using Geographic Information System (GIS) in producing Digital Elevation Model (DEM) for Dimas District, By applying various methods: Spatial Analyst, Geo Statistical Analyst, Triangulated Irregular Network (TIN), and interpolating DEM from contour lines. The study showed that the best methods for interpolating DEM is Kriging method, Which interpolated an evaluated surface for scattered points which had (Z values) whether they were closed or scattered from each other. And (TIN) method which required less area on hard disc to be stored comparing with other methods, and it's perfect for representing surfaces in wide areas, Also generating DEM from contour lines produced DEM which had very accurate representing for surfaces.

Using satellite images in updating topographic maps (An applicated study on Al-Bahlolia district)

The science and art of producing maps had been subjected to the changes as a result of new recent techniques developments at space photogrammetry, that lead to appearance of programs and applications in the computer's world. This associated with the advent of information age and Geographic information system that changed the traditional topographic map from just a map to an analyzing and viewing tool. All Syrian Topographic maps are old, out dated, and largely exist in paper form. Due to the high cost of aerial photography, These maps have not been updated for many years and such are not useful for planning. Therefore, there is an urgent need to produce new maps using high resolution satellite images. The research put a method for updating topographic maps of Al-Bahlolia district which have scales (1/50000) and (1/200000), By using Cartosat1 images. After updating, The results were that there is increasing in the area of planted land. In addition to building developments, increasing of length and density of roads between and inside villages. Contour lines also have been generated automatically, so efforts and time were be saved.

A Study of the Dental and Skeletal Features of the Anterior Open Bite in Permanent Occlusion in Syrian population in median region

The aim of This study was to identify the skeletal and dentoalveolar components in Syrian adult subjects whom have an anterior open bite by comparison with the normal occlusion subjects. This study showed elongation of upper and lower incisors, of upper molar height and increasing of anterior facial increasing height (P<0.05) in anterior open bite group compared with natural occlusion group .

Calibration Of some Mathematical Models To Estimate Tree Height Of Pinus brutia Ten. In Site Of Kfardabeel Stand- Jableh

This study aimed to estimate the height of the Pinus brutia trees in Kafardabeel forested area- Jableh. Eight mathematical forms (Michailoff, Prodan, Petterson, Parabel, Korsun, Logarithmic, Freese, Chapman-Richards) were used. In 2015, the diameter of 330 trees at breast height (dbh) were measured, and only heights of 165 of them were taken. Measurements were carried out in 15 sample plots all over the study area to cover site variations in altitude, exhibition, gradient and density. Data were split into two parts: 116 tree (70%) were used for model constrction, while the remaining trees 49 tree (30%) were used for model validation. The Results showed that, Parabel had the highest value for the Coefficient of Determination (R²=0.53) and the lowest value of the relative accuracy (mx%) (17.665%). That means it was the the best model to calculate tree height using diameter at breast height. This model can help foresters in forest management planning for study area and similar sites.

Algorithms Development for Emitter-location Determination Using Un-directional Antennas

This work discusses the feasibility of applying a small and inexpensive GPS, a Field Strength Meter (FSM) and a personal computer, that can activity and rapidly determine the Geo-locations of RF cooperated emitter, which have a wide range of both military and civilian applications. The emitter’s Geo-coordinates can be estimated by a single moving observation system, which receives signals from the emitter, and measures his Geo-locations and Field Strengths of the transmitted signal at four Positions Analytic Formulas are derived to calculate the location of Emitter, which detected from four Positions by using of Linear Algebra or pseudo range’s solution, The MATLAB was used to solve the four Equations and to simulate the Geo-Positions on Geo-Map.

Studying the growth and productivity of stone pine (Pinus pinea L.) Plantations in Daher khoraibat forest site -Snoubar Jableh – province Lattakia

The site was planted between 1960-1962 year with area size of 33 ha. The plots were systematically sampled with area size of 400 m2. The distance between plots was 100 m. Results showed that: trees number per hectare (N), stand average diameter (dbh) and height (H), basal area (G), productivity (V) and average annual growth (A.A.G) were: 237 tree/ha, 34.68 cm, 12 m, 21.91 m2/ha, 137.51 m3/ha and 2.64 m3/ha/year ; respectively. Stand height curve was developed with coefficient of determination of R2=0.50.

A Study of Subantral Height Changes in Sinus Membrane Elevation with Simultaneous Implants Insertion without Bone Grafts

This study aimed to study changes in subantral bony height when sinus membrane was elevated 6 mm without bone grafts depending on Cone Beam CT imaging. The study sample contained 18 implants placed on 11 patients of both genders, each patient underwent lateral-approach sinus-lift without bone grafts and implants were inserted simultaneously and protruded 6 mm under the elevated sinus membrane.

High Rise Buildings Precautions & Justifications & It's Specificity in Developing Countries

High rise buildings have an obvious effect on modern architecture. They raised an argumentation among various segments of society, specialists in forefront of them are architects and planners, in addition to an ordinary people. Administrative bodies and the public opinion involved many times in such matter especially in traditional character cities which have an architectural rootage. According to modern era features, high-rise buildings become a reality that couldn't be ignored worldwide, including developing countries. At the same time, it is not a destiny that couldn't be avoided, where many factors, cultural, social, economic, or technical, collectively or separately, plays a big role in adopting or avoiding such choice. Our research exposes this significant architecture subject, according to the principles and data of modern age, whereas it reviews the most important concepts and principles connected to it. Moreover, some of the most important experiments in this field are addressed through it the pros and cons that surrounded this topic especially in developing countries.
