Language plays an important role in communication to convey information between individuals, where communication is generally carried out verbally. However, not everyone can do so due to physical limitations, such as hearing or speech impairments. This research is intended to assist communication between individuals with physical limitations and those without. Therefore, this research designs a sign language detection system utilizing Supervised Learning, using Machine Learning models and the React JS library. The purpose of this research is to implement a sign language detection system and analyze user perceptions of the developed system. The research method used is Research and Development (R&D) with the ADDIE model. The research sample involved students from grades 1 to 6 at SLBN Purwakarta. System testing was carried out using black box testing and questionnaires. The results of this research show that the system can detect 15 BISINDO gestures, and the model achieved an accuracy rate of 93.8%. User perception analysis showed a percentage of 80.5%, indicating that the majority of respondents gave positive feedback based on the evaluation criteria
Generic injectivity of the Prym map for double ramified coverings
No full textIn this paper we consider the Prym map for double coverings of curves of genus ramified at points. That is, the map associating to a double ramified covering its Prym variety. The generic Torelli theorem states that the Prym map is generically injective as soon as the dimension of the space of coverings is less or equal to the dimension of the space of polarized abelian varieties. We prove the generic injectivity of the Prym map in the cases of double coverings of curves with: (a) , and (b) . In the first case the proof is constructive and can be extended to the range . For (b) we study the fibre along the locus of the intermediate Jacobians of cubic threefolds to conclude the generic injectivity. This completes the work of Marcucci and Pirola who proved this theorem for all the other cases, except for the bielliptic case (solved later by Marcucci and the first author), and the case considered previously by Nagaraj and Ramanan, and also by Bardelli, Ciliberto and Verra where the degree of the map is 3 . The paper closes with an appendix by Alessandro Verra with an independent result, the rationality of the moduli space of coverings with , whose proof is self-contained

Achieving regulatory efficiency: a study of the Greek telecommunications authority
No full textPhDThis thesis is an original examination of the structural characteristics that render an administrative agency, entrusted with the regulation of the telecommunications sector, ‘efficient’ or ‘better’ in the sense of the quality of its processes and decisions it makes or, in other words, what constitutes ‘good governance’. The author analyses the principles of good governance, since those principles affect the functioning of the regulator, the market and the regulatees’ rights, and discusses criteria which may be employed to measure each of the principles and hence good governance itself. Among those principles, regulatory independence and accountability are recognised as the cornerstones upon which ‘good regulation’ can be built. Firstly because accountability may be considered as a key principle of good governance, since, apart from its importance on its own, it is either strongly related to some of the pre-referred principles of good governance, such as transparency, or it is the tool to achieve the observance of other principles such as proportionality, consistency and predictability, effectiveness and due process. Secondly, independence is the cornerstone upon which stability, credibility, legal certainty, due process in the sense of the use of certain fair procedures such as participation, consultation and openness, economic efficiency, and transparency could be built. Without an independent regulator the possibilities for the development of the above notions are limited.
The two principles of good governance are further analysed in the thesis and their importance is demonstrated through the examination of a case study, the Greek national regulatory authority responsible for the regulation of the telecommunications sector. Through this case study it is demonstrated that the respect of a regulatee’s rights, the observance of the other principles of good governance and the good regulation of the market, mostly depend on the degree of independence and accountability of a regulatory body. The author argues that shortfalls of regulatory independence and accountability undermine regulatory performance and eventually good regulation. In this regard, the functioning of a regulatory body could be significantly improved, if reforms at European level are implemented, through the establishment of a single, pan-European regulatory authority and through more detailed regulatory measures at an EU level, and/ more regulations that do not require transposition.
In short, the aim of this thesis is to illustrate the critical role that regulatory independence and accountability play in achieving good governance in the telecommunications sector and indeed in other regulated sectors - such as energy and postal sectors, where a regulator is called to be efficient - as well as to discern policy lessons and to recommend legal measures designed to ensure more efficient regulators. Such lessons are seen as having particular relevance for new Member States of the European Union, such as Romania and Bulgaria, as well as for prospective accession states that may have broader applicability in new Member States and acceding countries. All these core issues are examined as up to December 2007
The singularities and birational geometry of the universal compactified Jacobian
No full textIn this paper we establish that the singularities of the universal compactified Jacobian are canonical if the genus is at least four. As a corollary we determine the Kodaira dimension and the Iitaka fibration of the universal compactified Jacobian for every degree and genus. We also determine the birational automorphism group for every degree if the genus is at least twelve. This extends work of G. Farkas and A. Verra, as well as that of G. Bini, C. Fontanari and the third author

Abstract: In today's era of globalization, technology is very important for humans, including in the sale and purchase of design or printing services. Trisindo Printing Dadap Jati is one of the companies engaged in printing. However, the running system process is still done manually and not computerized. This makes the sales, transaction and reporting processes within the company less effective and time-consuming. In addition, the company's sales can only reach customers from the surrounding area and its marketing techniques still use print media such as stickers, banners, and others. Therefore, the author provides a web-based design and print sales information system design at Trisindo Printing Dadap Jati so that companies can easily run work systems in each section, especially sales and marketing. Creating a web-based information system is certainly better than manually running information systems because it is more effective and efficient. The method used in this design is the waterfall method, where this design is made based on the wishes and needs of the company. With this system, it is expected that the sales and marketing processes within the company can work effectively, efficiently and maximally
