A New Class of Quasicyclic Complex Vector Functional Equations

For the first time in the literature a quasicyclic complex vector functional equation is introduced in the present paper. By a matrix method the general quasicyclic complex vector functional equation is solved, as well as its particular case for n = 3. This case is completely solved in an explicit form, and for every step of the solution examples are provided. Using a simple spectral property of compound matrices, a necessary and sufficient condition for stability of the quasicyclic complex vector functional equation considered is proved.</p

UN METODO NUOVO E PRECISO DI ACCORDARE LA CHITARRA

In this article is discussed a new method for tuning the guitar. This method is more precisely than other standard tuning methods considered in classical guitar methods. By this tuning method guitar is perfectly tuned in the open position.U ovom se članku procjenjuje nova metoda za uštimavanje gitare. Ova metoda je preciznija od standardnih metoda uštimavanja uzimajući u obzir metode klasične gitare. Pomoću ove metode gitara se savršeno uštimava na otvorenoj poziciji.In questo saggio si valuta un nuovo metodo di accordare la chitarra. Questo metodo è più preciso degli altri metodi standard usati per accordare la chitarra classica. Con questo metodo si può accordare la chitarra in modo perfetto in posizione aperta

El presente artículo intenta dar una opinión para hacer un nuevo acercamiento a la filosofía de la guitarra, de una manera suficientemente sofisticada, que supere todas las miradas hasta ahora conocidas. Con la idea de sacar a la luz este tema importante, el artículo introducirá una nueva filosofía de la guitarra en virtud al conocimiento músico-estético de lo clásico, para estimar los valores generales de los arreglos musicales. Con la idea de entender mejor esta aproximación, el énfasis se hace a través del prisma de la experiencia de guitarra y desde el punto de vista de nuevas necesidades para la literatura de la guitarra clásica.This paper intends to advance an opinion out of which we can give a new approach to the philosophy of guitar, in a sophisticated enough way that improves over the current views. With the idea of bringing to light this important topic, this paper will take us to a new philosophy of guitar in virtue of the musical-aesthetical &amp;nbsp;knowledge of the classical, to appreciate the general values of musical arrangements. Aiming to a better understanding of this approximation, emphasis is made through the prism of guitar experience and from the point of view of new needs for the literature of classical guitar

Recent Results from the RICE Experiment at the South Pole

We present a compilation of recent results, submitted to the 2003 International Cosmic Ray Conference (Tsukuba, Japan). These include: a) Revised Monte Carlo estimates of the radiofrequency signals produced by electromagnetic showers in ice, b) an updated search for ultra-high energy (UHE) neutrinos based on detection of radio-wavelength Cherenkov radiation; such radiation results from neutrino-induced electromagnetic showers in cold Polar ice, and c) An in situ measurement of the index of refraction through the South Polar firn.Comment: Compendium of RICE collaboration submissions to ICRC0

On what there is in philosophy of mathematics

En este artículo presentamos un bosquejo de diversos momentos que han ejercido una influencia considerable sobre el desarrollo de la filosofía de las matemáticas. Ilustramos los principales problemas de esta disciplina y discutimos el sentido y alcance de la denominada positividad de la matemática, Además mediante el examen de diversos enfoques sobre este tópico, analizamos algunas cuestiones epistemológicas y ontológicas  que pueden arrojar  algo de luz sobre esta complicada área de la metafilosofia.AbstractIn this paper we present an outline of various moments that have exerted considerable influence on the development of the philosophy of mathematics. We illustrate the main problems of this discipline and discuss the meaning and scope of the so-called positivity of mathematics, also by examining various approaches on this topic, we discuss some epistemological and ontological issues that may shed some light on this complicated area metaphilosophy.En este artículo presentamos un bosquejo de diversos momentos que han ejercido una influencia considerable sobre el desarrollo de la filosofía de las matemáticas.

ICE-B 2010:proceedings of the International Conference on e-Business

The International Conference on e-Business, ICE-B 2010, aims at bringing together researchers and practitioners who are interested in e-Business technology and its current applications. The mentioned technology relates not only to more low-level technological issues, such as technology platforms and web services, but also to some higher-level issues, such as context awareness and enterprise models, and also the peculiarities of different possible applications of such technology. These are all areas of theoretical and practical importance within the broad scope of e-Business, whose growing importance can be seen from the increasing interest of the IT research community. The areas of the current conference are: (i) e-Business applications; (ii) Enterprise engineering; (iii) Mobility; (iv) Business collaboration and e-Services; (v) Technology platforms. Contributions vary from research-driven to being more practical oriented, reflecting innovative results in the mentioned areas. ICE-B 2010 received 66 submissions, of which 9% were accepted as full papers. Additionally, 27% were presented as short papers and 17% as posters. All papers presented at the conference venue were included in the SciTePress Digital Library. Revised best papers are published by Springer-Verlag in a CCIS Series book

e-Business challenges and directions: important themes from the first ICE-B workshop

A three-day asynchronous, interactive workshop was held at ICE-B’10 in Piraeus, Greece in July of 2010. This event captured conference themes for e-Business challenges and directions across four subject areas: a) e-Business applications and models, b) enterprise engineering, c) mobility, d) business collaboration and e-Services, and e) technology platforms. Quality Function Deployment (QFD) methods were used to gather, organize and evaluate themes and their ratings. This paper summarizes the most important themes rated by participants: a) Since technology is becoming more economic and social in nature, more agile and context-based application develop methods are needed. b) Enterprise engineering approaches are needed to support the design of systems that can evolve with changing stakeholder needs. c) The digital native groundswell requires changes to business models, operations, and systems to support Prosumers. d) Intelligence and interoperability are needed to address Prosumer activity and their highly customized product purchases. e) Technology platforms must rapidly and correctly adapt, provide widespread offerings and scale appropriately, in the context of changing situational contexts
