Optimal power operation of low-cost MEMS-Based Attitude Determination System for Nano-satellites
No full textThe main purpose of this paper is to demonstrate the observed significance of power utilization and its operation within designed low-cost and optimal 3-Axis MEMS-Based Attitude Determination System for Nano-satellites. Nano-satellites have been most prominent portion of space research in the recent times and several of its real-time concerns requiring precise solution by maintaining appropriate balance of size, weight, cost and several other technical parameters pose a challenge in achieving enhanced missions objectives within this technology. In order to address these concerns relating to the attitude determination aspects of Nano-satellites, intensive research has been carried out through several statistical and experimental analyses to obtain a highly efficient, optimal and cost-effective attitude determination system specific to Nano-satellites. During the study and experimentation, many critical aspects have been significantly noted and unique conclusions have been made which are achieved by several creative and logical strategies, techniques and attitude dynamics. This paper will mainly focus on implementing efficient configurations to attain minimum power consumption especially using MEMS sensors acquired through practical scrutiny. A complete critical analysis is detailed after emphasizing the results which give substantial direction to make superior considerate and well-balanced applicability of low-cost sensors under severe space environment
A study of cognitive computing in nanosatellite constellations for synergic autonomy in CisLunar space
No full textThe small satellites have been changing the paradigm of space technology and implementation techniques ever since the NewSpace era has begun a stiff competition and dynamic atmosphere for innovation and recreation. Nanosatellites (ranging from 1 to 10 Kg) have been of significant importance since they have been launched and experimented in the past few decades. The constellations of these satellites will be a test of technology and management in due course of time. The complexity of operations and skilled functioning of the satellites in LEO and beyond is becoming crucial for the space industry and scientific communities. This paper will demonstrate the challenges, applications, and strategies to implement Artificial Intelligence (AI) optimally to make these constellations efficient and productive under the given scenarios and constraints. A thorough investigation through literature study has been initially done to observe and monitor the recent developments and envision the futuristic implementation of cognitive computing in CisLunar space. Hence, a detailed description of strategizing this artificial intelligence implementation in three classified regions as Low Earth Orbits (LEO), Transfer Region (TR), and Lunar Orbits (LO) to emphasize their crucial role in operating nanosatellites is significantly presented.

Strategic Vision, Infra-structure and Enhanced Configurations for Developing Cost-Effective Nano-satellites for Future Deep Space Missions
No full textThis paper attemps to present the major strategies to envision the further development of Nano-satellites (particularly in the range of 1 to 10 kilograms) and needed infra-structure to attain highly challenging mission objections in the near future which are presently delivered with larger satellites. The Nano-satellites to the most extent have proven their caliber in Low Earth Orbits (LEOs) due to several successful launches in the recent decades and based on practical observation, the capabilities possessed by these cost-effective technology based range of satellites can be aspired to explore various other portions of the deep space significantly. For this to be achieved, a detailed path has to be deviced at different levels of execution over a period of time with a completely dedicated thought process, planning, simulating, experimenting, evaluating and documenting respectively. In this research, the MEMS technology is considered to be most potential tool to maintain the cost-effectivity of Nano-satellites if implemented with well-balanced and space adoptable techniques. Hence, all these factors under scrutiny with a detail decription of combined benefits of MEMS and Nano-satellites which are contemplated for deep space exploration forms the nucleus of this paper. Lastly, A thorough critical analysis is presented with substantial conclusions
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
