A Transition-based Parser for Unscoped Episodic Logical Forms

Episodic Logic: Unscoped Logical Form'' (EL-ULF) is a semantic representation capturing predicate-argument structure as well as more challenging aspects of language within the Episodic Logic formalism. We present the first learned approach for parsing sentences into ULFs, using a growing set of annotated examples. The results provide a strong baseline for future improvement. Our method learns a sequence-to-sequence model for predicting the transition action sequence within a modified cache transition system. We evaluate the efficacy of type grammar-based constraints, a word-to-symbol lexicon, and transition system state features in this task. Our system is available at https://github.com/genelkim/ulf-transition-parser. We also present the first official annotated ULF dataset at https://www.cs.rochester.edu/u/gkim21/ulf/resources/.

Determination of the neutrino mass through the study of the energy spectrum of radiation of Strontium-90 isotope

In this work, using a scintillation detector with Strontium-90 source as a try to measure the electronic neutrino mass from a simple technique and different from what is used in this area where current techniques used are very complex and require substantial amounts. Also, detector calibration (to find the straight calibration equation), in addition to identified the maximum energy of β- particles (electrons), experimentally, by selection the channel number and then finding the energy value from the calibration equation (as a straight line). We have studied the disintegration changed energy with absorbent material which is an aluminum slices that have different thickness. We have observed the decrease in the values of the maximum energy of the electrons with increases the thickness of the slices. The energy changes with thickness as: E = f (x), (a straight line have a negative inclination). Applying Fermi 's theory and Kurie's plot allowed to find the maximum energy of disintegration electrons (1697,58 keV), this value is so close to experimental value (1653,45 keV), with dubity (2,6%) We have found that the electronic mass neutrino mass is almost to be non-existent, or we can said that the Strontium-90 disintegration does not allow to measure mass neutrino mass accurately, this is due to the high value of the disintegration energy of the Strontium- 90 isotope.

About the gravitation of material straight lines and rays

In this paper, we study the gravitational field generated by a material straight line around itself. We show the simplicity of the studied field, and we show its relation with the arc of half circle. We discussed also the subject of attracting two spacious straight lines, and we show the absence of relation between the mutual force and the distance. Also we study the field generated by a ray, where we present the different formulas for this field, and we show its geometrics properties, and its relation to a circular arc sees through it. Also studied the previous field lines, and we show that it are parabolas, and we appear by different ways that the equivalent surfaces are parabolic surfaces of revolution.

Analytical and experimental study of the effect of noise background on the radioactivity measurement

In this experimental work, the instruments used (detector, calibrating sources) has been calibrating, the calibration line of the detector deduced and it has been finding that the equation of calibration line takes the form: The resolution power R has been studying as function of the distance between the activity source and detector; the results obtained show that R decrease by increase the energy of the lines spectrum, this mean that the detector resolution power become bigger. It has been measured the LC، LD and MDA using two different methods of background radiation value, trapezium method and classical method, for two different distances between radioactivity source and detector: (9,3cm) and (10cm). The results show: 1- There is similar comportment of the LC، LD and MDA in function energy and the distance between radioactivity source and detector. 2- The trapezium method gives better results from the classical method to the radiation background, and this leads to lesser MDA value, this means that the sensibility is bigger to measure this quantity. 3- The relative error using MDA is (5%) for large values, and (10%) for small values

Using AutoCAD To Solve The Main Problems In Descriptive Geometry

The solution to many of the issues in Descriptive Geometry is easy when the issue in a particular case، so methods are used Descriptive Geometry to turn the issue of the general case to the special case to facilitate the resolution، and usually this is easy in some of the issues and the need for a set of steps in other issues، so we thought to take advantage of computer programs to solve some of these issues directly، or we will provide programming model on one of the issues to be resolved to facilitate and reduce the steps needed to reach a solution.

Ileal Pouch - Anal Anastomosis (IPAA) Study of 15 Cases

Evaluation of radical surgical treatment of colonic lesions which have the potential for malignant transformation, namely familial adenomatous polyposis (FAP) and ulcerative colitis (UC), by performing total proctocolectomy with ileal pouch-anal anastomoses (IPAA). This technique helps preserving the continuity of the gastrointestinal tract without the need for external enteral diversion.
