Abstract: Assessing the internal coherence and constituency of language families often centers either around comparing certain form-meaning correspondences, or around identifying the presence or absence of linguistic features across the members of the family. The former approach is generally restricted to the lexicon. The latter approach focuses mostly on structural characteristics of language. In this paper we present an alternative approach to comparing grammatical systems between languages within a language family, which aims at bringing these two approaches and their results closer to each other. We look at subordination strategies in a sample of Tupian languages, taking constructions as the basic unit of comparison, treating them as form-meaning correspondences. The Tupian family offers an especially intriguing case for studying subordination strategies in the South American context, given its enormous geographical spread and the variety of contact situations involving its member languages. Major patterns of subordination strategies can be discerned across the family, e.g. strategies involving nominalization, verbal incorporation and other subtypes of verbal serialization, but there is also a great degree of variability between the different languages. By mapping the structural diversity onto the known genealogy and geographic distribution, we hope to shed more light on the history of the Tupian family and on the diffusability of subordination strategies.

Abstract This paper deals with an important aspect of the integration of loan nouns into the grammatical systems of languages attesting to grammatical gender, namely gender assignment. Traditionally, it is assumed that gender assignment takes place according to the internal assignment rules of the replica language. In many cases, however, the original grammatical gender is borrowed along with the source word. This is the case of gender copy which often takes place under special (sociolinguistic) conditions and is used as assignment strategy in languages to a different extent. A special focus of my study is on gender assignment and particularly gender copy in the contact of languages of different assignment types (formal vs. semantic). The empirical data comes from five European languages in different sociolinguistic situations, attesting to different assignment systems and of different language branches of two language families – Indo-European (Romanian, Slavic, and Indo-Arian) and Nakh-Daghestanian (Lezgic and Tsezic). The analysis shows that gender copy is possible mostly in the contact of languages of the same assignment type. In the contact of languages of the formal assignment type, gender copy often goes along with the formal adjustment of the loan word. Sociolinguistic circumstances play an important role as to the possibility and frequency of the occurrence of gender copy.

This article approaches the origin of multilingual innovations in language contact by presenting data from an intensive contact situation between two closely related Finnic languages, Finnish and Estonian. This situation between languages that have complex interconnected morphological systems often leads to the emergence of structures that contain material from both languages. The origin of these structures is discussed in the light of two basic assumptions: that in the mind of the bilingual speaker, the elements of the two languages are connected to each other via phonological and semantic or functional similarities and that both languages of the bilingual speaker always remain active and available during speech processing. The simultaneous activation of synonymous, competing elements or patterns is hypothesised to be the cause for the inevitable presence of both language-internal and cross-linguistic forces at the initial stage of language change.

Numeral systems in natural languages show astonishing variety, though with very strong unifying tendencies that are increasing as many indigenous numeral systems disappear through language contact and globalization. Most numeral systems make use of a base, typically 10, less commonly 20, followed by a wide range of other possibilities. Higher numerals are formed from primitive lower numerals by applying the processes of addition and multiplication, in many languages also exponentiation; sometimes, however, numerals are formed from a higher numeral, using subtraction or division. Numerous complexities and idiosyncrasies are discussed, as are numeral systems that fall outside this general characterization, such as restricted numeral systems with no internal arithmetic structure, and some New Guinea extended body-part counting systems.

Abstract This paper examines current approaches to studying alignment change and the role of language contact in the spread of ergativity, using the Chukotkan languages as a case study. Chukotkan is exceptional in that there does not appear to be a single reanalysis pathway that can account for the development of ergative case. Rather, the system appears to be the product of several changes that operated in different domains. This paper provides an alternative to an earlier account that claims that Chukotkan ergativity developed due to Yupik substrate effects, which is not supported by the historical accounts of the contact between these groups. This explanation is consistent with a problematic tendency of treating ergativity as a special phenomenon, even though ergative alignment regularly arises via internal change. Instead, I propose that the loss of split ergative case marking occurred due to the reanalysis of a passive participle, which was motivated by the tendency to encode animacy distinctions in these languages.

Language changes and developments, both nationally and internationally, are inevitable due to cultural acculturation and interactions between speakers of different languages. These changes can be internal, affecting the grammar system, or external, influenced by contact with other languages. Internal changes, which occur gradually, involve alterations in phonological systems, phrase order, and case and gender functions. External changes, resulting from interactions driven by economic, political, educational, and technological interests, can occur rapidly, often starting with lexical enrichment and extending to other language elements. This study examines the historical development and changes in two languages from the same family, German and English, to illustrate internal changes. Additionally, it explores the impact of external changes in multilingual societies, emphasizing the role of sociolinguistics in understanding the relationship between language and society. The methodology involves a qualitative approach, literature review, participant observation, and interviews to gather and analyze data descriptively. The study finds that internal language changes are driven by speaker behavior and innovation within communities, while external changes result from language contact and social interactions. These interactions lead to the introduction of loanwords, new morphological elements, phonemes, and speech variations. Examples from Indonesian, German, and English demonstrate how languages evolve due to these influences, creating new dialects and hybrid languages. The research highlights the importance of sociolinguistics in describing social status, improving social mobility through language use, and investigating dialect phenomena. The findings emphasize that language is a dynamic entity, constantly adapting to social, cultural, and technological changes, reflecting the diverse and evolving nature of human communication.

Recent studies in contact linguistics have emphasized the aspect of language-internal grammaticalization that is triggered by accommodation to an external (contact-language) model (e.g. Heine and Kuteva, 2005). This is based on the notion that speakers make use of the available resources in order to match them to those of the target language. A problematic issue is contact-induced change in the domain of case representation. Synthetic case markers are usually thought of as fully grammaticalized morphemes. If contact-induced grammaticalization is, as Heine and Kuteva suggest, much like monolingual grammaticalization, unidirectional, how do we treat instances of rearrangement of the semantic meaning and scope of case markers? I will discuss this problem by examining a sample of Romani dialects, belonging to the so-called Northeastern dialect group (see Matras, 2002). Relying on specific constructions, like Subject of Negative Existence, External Possession, Privative, Partitive etc., I will compare and contrast the Northeastern dialects with their respective contact languages (Russian and Polish). Using semantic maps, I will demonstrate how the Romani dialects in question restructure their case representation system to accommodate to the systems of the model languages, and will discuss what it is exactly that gets equated when two languages come into contact.

This article explores the phenomenon of code-switching, specifically focusing on bilingual Arabic-Italian determiner phrases which consist of a determiner, such as an article or a demonstrative, followed by a noun phrase as a complement. The data examined were selected from a corpus of Arabic-Italian spontaneous speech with the aim of (1) comparing and describing the characteristics and differences of the determiner systems of the two languages; (2) illustrating the features of code-switching in determiner phrases and the various types found in the collected data; and (3) studying the mutual influence of the two languages in contact contexts. The data analysis revealed two types of code-switching: switching at the beginning of a determiner phrase, where both the determiner and its complement are in the same language, and switching within a determiner phrase, where the determiner and the head noun are from different languages. This latter category also includes determiner phrases with double determiners, which will be analyzed in detail in this article to discuss the features of this linguistic structure in Arabic-Italian bilingual phrases.

The article focuses on orographic appellatives and oronyms derived from anatomical terms in the Yakut language through metaphorization. Given that the Yakut oronymy is endangered due to several sociolinguistic and socio-economic reasons, collecting, systematizing, studying, and preserving this specific layer of the Yakut toponymic lexicon in linguistic databases is relevant. We have identified more than 80 anatomical terms that contributed to the Yakut oronymy development. We divided the Yakut anatomical vocabulary used as orographic appellatives into two groups: 1) lexemes denoting the external parts of human and animal bodies and 2) lexemes denoting the internal organs of humans and animals. The comparative analysis covered the following anatomical terms: atax ‘leg’, bas ‘head’, sürex ‘heart’, tumus ‘nose; beak’, kulgaax ‘ear’, töbö ‘head’, meyii ‘brain’, emiy ‘udder’. The comparison has demonstrated a substantial similarity in the anatomical vocabulary used as orographic appellatives in the Turkic languages. However, some Turkic languages feature divergence in terms of content, possibly resulting from the influence of contact languages (related and unrelated). The abundance and variety of metaphorical anatomical terms in different Turkic languages may also be due to the physical and geographical features of the terrain on which they function. Given the above, the anatomical vocabulary can be considered an additional source for understanding the formation patterns and features of the Turkic-Mongolian geographical vocabulary of Siberia.

The paper presents the analysis of Fula numeral system. Fula is an Atlantic language, dispersed throughout a vast territory in Sub-Saharan Africa. It has over 20 differently-sized lects subdivided into three zones - Western, Central and Eastern. The research included collecting the language data on six major lects, two from each zone. Then this data was analyzed from the point of view of internal and external syntax of ordinal, cardinal, distributive and fraction numerals. The comparative analysis of Fula numeral system on inter-lect scale has never been reflected in earlier Fula studies. Apart from a unique collection of numeral data from all language zones of Fula, the paper presents comparative analysis of such data, including, but not limited to, phonetic and contact-induced variabilities. The sources of structural and lexical loans in the system are listed wherever possible, because the disperse nature of Fula lects means that the contact languages and the ensuing changes can be different for each lect. Special attention is paid to the numeral bases, which can be somatic, commercial of a combination of the two. The Fula numeral system has never been analyzed from this point of view, and the contact changes to it are of great linguistic interest. Also cardinal numerals in Fula can change their form depending on the personality parameter of head noun. This system is unique for Fula and, more specifically, to its numeral system, and is properly described for the first time. Some parts of the Fula numeral system, like distributive and fraction numerals for some lects, have been found underrepresented and poorly described, which leaves room for further research, both field one and typological.

Cette recherche se concentre sur les erreurs globales relevées dans les corpus collectés auprès des apprenantsdu français de l’université d’Arsi. À travers une étude comparative, l'objectif principal de cette recherche est,d'une part, d'examiner si les erreurs constatées sont dues à l'interférence des langues premières (L1) et,d'autre part, de déterminer si ces erreurs apparaissent à chaque niveau linguistique. Il s'agit donc d'évaluer sicette interférence affecte l'acquisition de la langue cible au niveau phonétique, morphologique et syntaxique.Au contexte de la didactique, certaines stratégies d'enseignement, introduites par un certain nombred'auteurs, sont proposées afin d’enseigner la production des sons uniques, la formation et l’assemblage desmots
This research focuses on global errors found in corpora collected from learners of French at the University ofArsi. Through a comparative study, the main aim of this research is, on the one hand, to examine whether theerrors noted are due to interference from the first languages (L1) and, on the other, to determine whetherthese errors appear at each linguistic level. The aim is therefore to assess whether this interference affects theacquisition of the target language at the phonetic, morphological and syntactic levels. In the context ofdidactics, certain teaching strategies, introduced by certain authors, are proposed to teach the production ofsingle sounds, word formation and word

The book constitutes the second volume of the two-volume work The history of negation in the languages of Europe and the Mediterranean. While the first volume united a rich collection of ten case studies, the current second volume turns to the patterns and processes in the historical development of the expression of negation and its interaction with indefinites from a more general theoretical perspective. The volume is subdivided into two parts, one dealing with Jespersen’s cycle and one dealing with developments affecting indefinites in the scope of negation (the quantifier and free-choice cycles), including the diachronic development of negative concord. In each case, there are relevant empirical observations across the languages of Europe and the Mediterranean. The book considers both language-internal and language-contact motivations for the changes observed, developing a generative account of the developments in terms of semantic change, reanalysis, and child-language acquisition, integrating insights from functionalist approaches that invoke language use as a motivation behind these cycles. Language contact is shown to have played a significant role in the spread of negation systems. The result is a holistic account of language change in the domain of negation, developed from comparing the diachronies of languages across Europe and incorporating insights from a wide range of theoretical perspectives.

The monograph reflects the problems of Russian psycholinguistics from the moment of its inception in Russia to the present day and presents its main directions that are currently developing. In addition, theoretical developments and practical results obtained in the framework of different directions and research centers are described in a concise form. The task of the book is to reflect, as far as it is possible in one edition, firstly, the history of the formation of Russian psycholinguistics; secondly, its methodology and developed methods; thirdly, the results obtained in different research centers and directions in different regions of Russia; fourthly, to outline the main directions of the further development of Russian psycholinguistics. There is no doubt that in the theoretical, methodological and applied aspects, the main problems and the results of their development by Russian psycholinguistics have no analogues in world linguistics and psycholinguistics, or are represented by completely original concepts and methods. We have tried to show this uniqueness of the problematics and the methodological equipment of Russian psycholinguistics in this book. The main role in the formation of Russian psycholinguistics was played by the Moscow psycholinguistic school of A.A. Leontyev. It still defines the main directions of Russian psycholinguistics. Russian psycholinguistics (the theory of speech activity - TSA) is based on the achievements of Russian psychology: a cultural-historical approach to the analysis of mental phenomena L.S. Vygotsky and the system-activity approach of A.N. Leontyev. Moscow is the most "psycholinguistic region" of Russia - INL RAS, Moscow State University, Moscow State Linguistic University, RUDN, Moscow State Pedagogical University, Moscow State Pedagogical University, Sechenov University, Moscow State University and other Moscow universities. Saint Petersburg psycholinguists have significant achievements, especially in the study of neurolinguistic problems, ontolinguistics. The most important feature of Russian psycholinguistics is the widespread development of psycholinguistics in the regions, the emergence of recognized psycholinguistic research centers - St. Petersburg, Tver, Saratov, Perm, Ufa, Omsk, Novosibirsk, Voronezh, Yekaterinburg, Kursk, Chelyabinsk; psycholinguistics is represented in Cherepovets, Ivanovo, Volgograd, Vyatka, Kaluga, Krasnoyarsk, Irkutsk, Vladivostok, Abakan, Maikop, Barnaul, Ulan-Ude, Yakutsk, Syktyvkar, Armavir and other cities; in Belarus - Minsk, in Ukraine - Lvov, Chernivtsi, Kharkov, in the DPR - Donetsk, in Kazakhstan - Alma-Ata, Chimkent. Our researchers work in Bulgaria, Hungary, Vietnam, China, France, Switzerland. There are Russian psycholinguists in Canada, USA, Israel, Austria and a number of other countries. All scientists from these regions and countries have contributed to the development of Russian psycholinguistics, to the development of psycholinguistic theory and methods of psycholinguistic research. Their participation has not been forgotten. We tried to present the main Russian psycholinguists in the Appendix - in the sections "Scientometrics", "Monographs and Manuals" and "Dissertations", even if there is no information about them in the Electronic Library and RSCI. The principles of including scientists in the scientometric list are presented in the Appendix. Our analysis of the content of the resulting monograph on psycholinguistic research in Russia allows us to draw preliminary conclusions about some of the distinctive features of Russian psycholinguistics: 1. cultural-historical approach to the analysis of mental phenomena of L.S.Vygotsky and the system-activity approach of A.N. Leontiev as methodological basis of Russian psycholinguistics; 2. theoretical nature of psycholinguistic research as a characteristic feature of Russian psycholinguistics. Our psycholinguistics has always built a general theory of the generation and perception of speech, mental vocabulary, linked specific research with the problems of ontogenesis, the relationship between language and thinking; 3. psycholinguistic studies of speech communication as an important subject of psycholinguistics; 4. attention to the psycholinguistic analysis of the text and the development of methods for such analysis; 5. active research into the ontogenesis of linguistic ability; 6. investigation of linguistic consciousness as one of the important subjects of psycholinguistics; 7. understanding the need to create associative dictionaries of different types as the most important practical task of psycholinguistics; 8. widespread use of psycholinguistic methods for applied purposes, active development of applied psycholinguistics. The review of the main directions of development of Russian psycholinguistics, carried out in this monograph, clearly shows that the direction associated with the study of linguistic consciousness is currently being most intensively developed in modern Russian psycholinguistics. As the practice of many years of psycholinguistic research in our country shows, the subject of study of psycholinguists is precisely linguistic consciousness - this is a part of human consciousness that is responsible for generating, understanding speech and keeping language in consciousness. Associative experiments are the core of most psycholinguistic techniques and are important both theoretically and practically. The following main areas of practical application of the results of associative experiments can be outlined. 1. Education. Associative experiments are the basis for constructing Mind Maps, one of the most promising tools for systematizing knowledge, assessing the quality, volume and nature of declarative knowledge (and using special techniques and skills). Methods based on smart maps are already widely used in teaching foreign languages, fast and deep immersion in various subject areas. 2. Information search, search optimization. The results of associative experiments can significantly improve the quality of information retrieval, its efficiency, as well as adaptability for a specific person (social group). When promoting sites (promoting them in search results), an associative experiment allows you to increase and improve the quality of the audience reached. 3. Translation studies, translation automation. An associative experiment can significantly improve the quality of translation, take into account intercultural and other social characteristics of native speakers. 4. Computational linguistics and automatic word processing. The results of associative experiments make it possible to reveal the features of a person's linguistic consciousness and contribute to the development of automatic text processing systems in a wide range of applications of natural language interfaces of computer programs and robotic solutions. 5. Advertising. The use of data on associations for specific words, slogans and texts allows you to predict and improve advertising texts. 6. Social relationships. The analysis of texts using the data of associative experiments makes it possible to assess the tonality of messages (negative / positive moods, aggression and other characteristics) based on user comments on the Internet and social networks, in the press in various projections (by individuals, events, organizations, etc.) from various social angles, to diagnose the formation of extremist ideas. 7. Content control and protection of personal data. Associative experiments improve the quality of content detection and filtering by identifying associative fields in areas subject to age restrictions, personal information, tobacco and alcohol advertising, incitement to ethnic hatred, etc. 8. Gender and individual differences. The data of associative experiments can be used to compare the reactions (and, in general, other features of thinking) between men and women, different social and age groups, representatives of different regions. The directions for the further development of Russian psycholinguistics from the standpoint of the current state of psycholinguistic science in the country are seen by us, first of all:  in the development of research in various areas of linguistic consciousness, which will contribute to the development of an important concept of speech as a verbal model of non-linguistic consciousness, in which knowledge revealed by social practice and assigned by each member of society during its inculturation is consolidated for society and on its behalf;  in the expansion of the problematics, which is formed under the influence of the growing intercultural communication in the world community, which inevitably involves the speech behavior of natural and artificial bilinguals in the new object area of psycholinguistics;  in using the capabilities of national linguistic corpora in the interests of researchers studying the functioning of non-linguistic and linguistic consciousness in speech processes;  in expanding research on the semantic perception of multimodal texts, the scope of which has greatly expanded in connection with the spread of the Internet as a means of communication in the life of modern society;  in the inclusion of the problems of professional communication and professional activity in the object area of psycholinguistics in connection with the introduction of information technologies into public practice, entailing the emergence of new professions and new features of the professional ethos;  in the further development of the theory of the mental lexicon (identifying the role of different types of knowledge in its formation and functioning, the role of the word as a unit of the mental lexicon in the formation of the image of the world, as well as the role of the natural / internal metalanguage and its specificity in speech activity);  in the broad development of associative lexicography, which will meet the most diverse needs of society and cognitive sciences. The development of associative lexicography may lead to the emergence of such disciplines as associative typology, associative variantology, associative axiology;  in expanding the spheres of applied use of psycholinguistics in social sciences, sociology, semasiology, lexicography, in the study of the brain, linguodidactics, medicine, etc. This book is a kind of summarizing result of the development of Russian psycholinguistics today. Each section provides a bibliography of studies on the relevant issue. The Appendix contains the scientometrics of leading Russian psycholinguists, basic monographs, psycholinguistic textbooks and dissertations defended in psycholinguistics. The content of the publications presented here is convincing evidence of the relevance of psycholinguistic topics and the effectiveness of the development of psycholinguistic problems in Russia.

Why do grammatical systems of various languages express different meanings? Given that languages spoken in the same geographical area by people sharing similar social structure, occupations, and religious beliefs differ in the kinds of meaning expressed by the grammatical system, the answer to this question cannot invoke differences in geography, occupation, social and political structure, or religion. The present book aims to answer the main question through language internal analysis. This book offers a methodology to discover meaning in a way that is not based on inferences about reality. The book also offers a methodology to discover motivations for the emergence of meanings. The grammatical system at any given time constitutes a base from which new meanings emerge. The motivations for the emergence of functions include: the communicative need triggered when the grammatical system inherently produces ambiguities; the principle of functional transparency whereby every function encoded in the grammatical system must be expressed if it is in the scope of the situation described by the proposition; opportunistic emergence of meaning whereby unoccupied formal niches acquire a new function; metonymic emergence whereby a property of an existing function receives a formal means of its own, thus creating a new function; emergence of functions through language contact. Several phenomena, such as benefactive and progressive in English, as well as point of view of the subject and goal orientation in several languages, receive new analyses.

This chapter aims to present a system for remote laboratories dedicated to solar cells in the context of contemporary research development in the field of renewable energy. The system is based on the NI ELVIS rapid prototyping platform, the LabVIEW graphical programming language, remote control techniques, and an original add-on for studying solar cells developed for the platform. The completed NI ELVIS add-on, called SolarLab, is a modular board, which allows users to perform eighteen different lab experiments. Using the developed driver, users can create their own applications according to their needs. Thus, SolarLab can be used for both education and research purposes.

In 1995, based on an earlier survey by the U.S. Bureau of Labor Statistics (USBLS), Boehm predicted that the number of end-users performing programminglike tasks would reach 55 million by 2005 (Boehm, Clark, Horowitz, Madachy, Selby & Westland, 1995). Adjusting this information for the accelerated rate of computer usage and other factors, Schaffidi, Shaw, and Myers (2005b) now predict the end-user population at American workplaces will increase to 90 million by 2012, and that these workers will probably execute some type of programming-like task. In a 2004 report, USBLS published projections of occupational growth patterns to 2012 and reported slightly over 3 million professionals in computer-programming occupations in 2002. To summarize, the probability is that 90 million end-users are engaged in programming-like tasks at work compared to only 3 million professionally trained programmers. Thus, the pool of end-user programmers will substantially exceed the small population who view themselves as programmers for the foreseeable future. Programming systems employed by end-users include spreadsheets, Web authoring tools, business authoring tools, graphical languages, and scripting and programming languages (Myers, Ko & Burnett, 2006). Myers et al. (2006) estimates that 50 million people in American workplaces currently use spreadsheets or databases (and therefore may do programming). More specifically, Myers et al. (2006) estimates that over 12 million people in the workplace would say that they actually do programming at work. This diverse and growing population of end-user developers performing programming-like tasks is researched with respect to the emerging subpopulations forming around application specific activities (e.g., spreadsheets, database, Web development). Each of these subpopulations or communities of end-users has characteristic needs and abilities requiring specialized attention. There are even more end-users participating in Internet- based tasks related to programming. During 2003, the Pew Internet and American Life Project found that more than 53 million American adults used the Internet to publish their thoughts, repond to others, post pictures, share files and otherwise contribute to the explosion of content available online. At least 13% (nearly 7 million) of those Internet users claimed they maintained their own Web sites (Pew Internet and American Life Project, 2003). We characterize this nonprofessional population as end-user web developers, in that they have not been trained to develop software as part of their work responsibilities, but nevertheless have found themselves developing and maintaining Web content more and more as part of their daily activities. This review targets this large and growing population, one that presents both opportunities and challenges for information systems researchers studying Web development tools, resources, and education.

Numerous learning management systems exist that support the process of e-learning all over the world. Japan is no exception and the University of Tsukuba in Japan employs manaba, a cloud-based collaborative learning system developed by the Internet service provider Asahi NET, Inc., which allows switching between English and Japanese interfaces. The University of Tsukuba is also the home of several undergraduate programs taught entirely in English, as part of the Global 30 Project. While all students in this program are international students, the vast majority of them are non-native English speakers. Our paper focuses on the impact of using a Japanese/English learning management system on the studying habits of non-native English speaking international students in Japan. We conducted an empirical study involving 30 international students and we collected data regarding the students' experience with the manaba learning management system. The subjects in our study, Global 30 social studies undergraduate students, come from more than 20 different countries, on 4 different continents, with only a small number originating from English-speaking countries. Based on a number of questionnaires, the aim of our study is to reveal the subjects' views with regard to manaba on aspects like: overall usefulness, difficulty of using one language interface or the other, level of interaction with the course instructor, usefulness of features like reminders, notifications etc. Furthermore, we intend to observe how different cultural backgrounds influence the way that learning management systems are approached by different students. Last but not least, we intend to analyze the extent to which the e-learning content is accessed using a mobile device as opposed to a personal computer. We believe that our paper can offer an interesting view on the cultural dimensions of using a learning management system in a Japanese heterogeneous academic group.

Abstract Drilling operations can induce several external excitations to the drillstring and bottom-hole assembly (BHA) due, namely, to the drillstring-wellbore contacts, bit-rock interactions, fluid flow, and mass imbalances. On the one hand, such undesirable excitations may lead to excessive vibrations and damage to the drill bit, BHA, or drill-pipes. On the other hand, some vibration tools are used to intentionally introduce a source of lateral vibrations in the drillstring to reduce the friction effects and enhance the rate of penetration. Whether these vibrations are undesirable or intentional, efficient models are necessary to predict them accurately to help optimize the drilling parameters and vibration tools placement in the drillstring. The time-domain analysis can give a detailed portrayal of drillstring vibrations, but usually requires a lengthy computational time, especially for the simulation of long structures. This paper focuses on an alternative analysis using a forced vibration model based on a linearized frequency analysis. It consists of studying the magnitude of the displacement, velocity, acceleration, and internal efforts, when the drillstring is subject to an external harmonic excitation at a given frequency. This numerical model is based on the beam finite element method, where the wellbore-drillstring contact effects are considered using a Jacobian matrix approach. The forced vibration model is applied to study the lateral vibrations produced either by mud motors or lateral vibration tools. The comparison between the results of frequency and time-domain analyses shows that the forced vibration model can describe the global behavior of drillstring vibrations with a fast computation. When varying the excitation frequency, critical values giving large vibrations could be identified and avoided by the driller thanks to a heat map representation of the vibration magnitude as a function of the position and excitation frequency. The novelty of this work is in showing the capacities and limitations of the forced vibration analysis compared to time-domain analysis. The fast computation of the frequency analysis can provide efficient and accurate predictions and, therefore, could be employed to optimize the BHA design and drilling parameters, and therefore reduce the harmful vibrations and improve the performance of any drilling systems equipped with downhole excitation tools.
