Check Method

In computer network communication, adopted the error-check control methods to reduce the error code frequency of data transmission commonly. The CRC (Cyclic Redundancy Check) method is the best one of them. This paper analyzed the principle and the check rules of CRC algorithm. For the CRC algorithm of bytes operation, proposed a new table-driven algorithm which is visual, compact and easy to be understood. A strict mathematic proof of the CRC algorithm is given. By diagrammatizing, deduct the calculated process of CRC-ITU and CRC-32 code in detail. At the same time, we designed a concise CRC-ITU algorithm with assembly language similarly, and discussed the method using the remainder of F(x)/G(x) as a surveillance code briefly.

Niche Models

This chapter considers the practice of modeling ecological niches and estimating geographic distributions. It first introduces the general principles and definitions underlying ecological niche modeling and species distribution modeling, focusing on model calibration and evaluation, before discussing the principal steps to be followed in building niche models. The first task in building a niche model is to collate, process, error-check, and format the data that are necessary as input. Two types of data are required: primary occurrence data documenting known presences (and sometimes absences) of the species, and environmental predictors in the form of raster-format GIS layers summarizing scenopoetic variables that may (or may not) be involved in delineating the ecological requirements of the species. The next step is to use a modeling algorithm to characterize the species’ ecological niche as a function of the environmental variables, followed by model projection and evaluation and finally, model transferability.

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.

Force Components

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.

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.

AbstractAccurate 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.
