The Effect of Online Grammatical Error Check on the Improvement of L2 Writing

One of the most challenging language skills is the mastery of the target language's academic writing. To perfect academic writings, many English learners have sought help from different online error checkers websites. Yet, little is known about their benefits on improving grammatical errors, in particular and academic writing, in general. This quantitative study was designed to investigate preparatory Saudi English learners' standpoints about their reasons and attitudes towards the use of the different online websites such as Google Translate, Grammarly, Grammar Check, and others to improve English academic writings, in general and the most frequent errors, in particular. The data was collected through an online survey (N=115) composed of 23 items. Results show that students' main aim of using those programs is to get high marks and improve their writing style. It is also found that many students have benefited from online error checkers websites and the most frequent writing errors have been minimized. It is aimed that the finding may equip students with some learning strategies to enhance the quality of their writing efficiency through the use of online error checkers programs. Additionally, the result may set grounds for pedagogues to harness innovative teaching techniques that effectively utilize online error checkers to maximize students' language writing performance.

Unused resources in global maritime distress safety system: digital selective call

Цифровой избирательный вызов (ЦИВ) в Глобальной морской системе связи при бедствии и безопасности не позволяет передавать какой-либо текст, содержание которого отличается от разрешённых возможностей в семи форматах ЦИВ. Использование биграмм и триграмм для интерпретации произвольного текста и неиспользованные резервы в символах управления в форматах ЦИВ могут изменить эту ситуацию. Эта идея может быть распространена, по меньшей мере, на языки, в которых используется буквенный принцип записи текста. Идея остаётся в силе для языков с иероглифической формой записи, если существует ещё и альтернативная буквенная форма представления текста, подобная Путунхуа в китайском языке. Использование преимуществ ЦИВ в возможности определения ошибки в каждом принятом символе, двойная передача символов (в DX и RX позициях) даёт возможность изменения принципов приёма информации по безопасности мореплавания. Более того, НАВ-ТЕКС и ИБН УБПЧ можно объединить в одну общую систему передачи информации по безопасности мореплавания. Существует возможность исправления ошибок при принятии символов в расширенном цифровом избирательном вызове, используя перестановку символов при многоканальной трансляции информации по безопасности мореплавания. Как результат, будет отсутствовать необходимость учёта 4% норматива ошибок на объём принятого текста, поскольку ошибки в принятом тексте отсутствуют. Предложены способы организации произвольных сообщений и сообщений по безопасности мореплавания на английском и русском языках со сжатием информации при помощи расширенного цифрового избирательного вызова. Digital Selective Call (DSC) in Global Maritime Distress Safety System does not allow to broadcast any information that differs from allowed abilities in seven DSC formats. Using bigrams and trigram for interpretation of custom text and unused reserve of control char-acters in DSC formats would change this situation. This idea can be extended at least to the languages with a letter form of writing text. It is in valid for languages with hiero-glyphic notation, if alternative letter additional form exists, like Putonghua in Chinese language. Using DSC advantages in possibility error detecting in every received symbols, two times transmission of symbols (in DX and RX positions) and error-check characters in DX and RX positions give the opportunity to change principles of Maritime Safety Infor-mation (MSI) to be received on board the vessels. Moreover, NAVTEX and MSI NBDP systems can be combined in one common system. There is a possibility to correct errors in received symbols in Advanced Digital Selective Call using permutation of characters in multi-channel MSI broadcasting. As result, there is no need to use four percent reference error rate at received MSI text volume, because broadcasted information has not errors. Ways to organize self-compressing custom messages and Maritime Safety Information messages in English and Russian by Advanced Digital Selective Call has been offered.

Parallel Computation of CRC-Code on an FPGA Platform for High Data Throughput

With the rapid advancement of radiation hard imaging technology, space-based remote sensing instruments are becoming not only more sophisticated but are also generating substantially more amounts of data for rapid processing. For applications that rely on data transmitted from a planetary probe to a relay spacecraft to Earth, alteration or discontinuity in data over a long transmission distance is likely to happen. Cyclic Redundancy Check (CRC) is one of the most well-known package error check techniques in sensor networks for critical applications. However, serial CRC computation could be a bottleneck of the throughput in such systems. In this work, we design, implement, and validate an efficient hybrid look-up-table and matrix transformation algorithm for high throughput parallel computational unit to speed-up the process of CRC computation using both CPU and Field Programmable Gate Array (FPGA) with comparison of both methods.

An Automated Velocity Dealiasing Scheme for Radar Data Observed from Typhoons and Hurricanes

Accurate and automated dealiasing of radar data is important for data interpretation and downstream applications such as numerical weather prediction (NWP) models. In this paper an improved radial velocity dealiasing scheme is presented and evaluated using observations from several S-band radars under the severe weather conditions of typhoons and hurricanes. This scheme, named Automated Dealiasing for Typhoon and Hurricane (ADTH), is a further development of the China New Generation Doppler Weather Radar (CINRAD) improved dealiasing algorithm (CIDA). The upgraded algorithm ADTH includes three modules designed to select the first radial from which the dealiasing process starts, to conduct a two-way multipass dealiasing, and to perform an error check for a final local dealiasing. The dealiasing algorithm is applied to two typhoon hurricane cases and four typhoon cases observed with radars from CINRAD, NEXRAD of the United States, and the Taiwan radar network for a continuous period of 12 h for each of the selected cases. The results show that ADTH outperforms CIDA for all of the test cases.

Function Transformations and the Desmos Activity Builder

In my classroom, the Desmos® calculator has been a game-changer for student understanding of relationships between graphs and algebraic representations of functions. We use this beautifully designed website every day. Lately, the Desmos class activity site (https://teacher.demos.com) and the new Activity Builder tool have proven especially useful by allowing me to provide my students with opportunities to struggle productively, create, error-check, and think deeply to learn mathematics. Activity Builder is the easiest tool I have found to set up and to run an activity that promotes these ideas in your classroom.

Colloquium Response

The problem for Study of Religions (sor) in the academy is the dearth of successful theory-as-explanation in the field and the consequential domination of the public square by other voices namely theology, apologetics, humanist study that privileges belief and New Atheism. There is theory-as-critique aplenty and it is applied to both religious truth claims and to explanatory theories about religion. Scholars ofsorhave the critical tools, methods, expertise and weight of scholarship to error check and to disprove naturalistic explanations but finding explanatory ground to stand on is very hard indeed. This piece argues that it is important to renew and revitalise the search for explanation.

Determination of Cutting Forces in Oblique Cutting

This study describes the method of determining cutting force components in oblique turning. The scheme of how the investigations were performed is presented. The characteristic curves of cutting force components vs. thickness of the material removed, tool clearance and tool rake angles are shown. The study presents the data, which have been obtained during the experimental investigations and analytically calculated, on how the cutting forces are subject to changes depending on a cutter angle, cutting depth and feed in oblique turning operations. The analysis of approximation of the experimental results and error check of the theoretical calculations relative to the experimental data are given.
