Acoustic positioning and orientation prediction
A method is described for use with an acoustic positioner, which enables a determination of the equilibrium position and orientation which an object assumes in a zero gravity environment, as well as restoring forces and torques of an object in an acoustic standing wave field. An acoustic standing wave field is established in the chamber, and the object is held at several different positions near the expected equilibrium position. While the object is held at each position, the center resonant frequency of the chamber is determined, by noting which frequency results in the greatest pressure of the acoustic field. The object position which results in the lowest center resonant frequency is the equilibrium position. The orientation of a nonspherical object is similarly determined, by holding the object in a plurality of different orientations at its equilibrium position, and noting the center resonant frequency for each orientation. The orientation which results in the lowest center resonant frequency is the equilibrium orientation. Where the acoustic frequency is constant, but the chamber length is variable, the equilibrium position or orientation is that which results in the greatest chamber length at the center resonant frequency
Industry 5.0 narrative: utopia and reality
The paper analyses INDUSTRY 5.0 definition and its narrative on a broad and didactical discussion to explain and clarify is better thanking care of the narrative, political fashions, and gurus. We need to start with figures. A start should be a deep understanding of the information economy and a critique of the INDUSTRY 4.0 definition. The sustainable development and human wellbeing narrative is an umbrella for discussion used especially today as political goals. But when we seek global indexes, it is easy to see how is manipulated the general narrative. The result and the suggestion of the paper are to change the horizon and the goals of the new INDUSTRY 5.0 narrative into a new Social and environmental development model starting from the economics drivers and avoiding the false narrative of a technology or fake environmental ideology-driven pink futureThe paper analyses INDUSTRY 5.0 definition and its narrative on a broad and didactical discussion to explain and clarify is better thanking care of the narrative, political fashions, and gurus.

Fill the gap between public administration strategic management and plan man-agement. The italian PNRR and digital transition case
The paper tries to clarify the gap between strategic management and plan management. This gap is not the only one in European and Italian plans. The research starts from the observation that co-governance between the central government and municipalities and local government failed in Italy so then the reforms and investment expected outcomes are at risk. The problem was detected when the author worked as a consultant in the last Italian resilience (PNRR) and digital (DTI) plans in 2022. To work together and have coordinated goals, PNRR and DTI must have a strategic control room and network governance very different from the one decided in 2019 (PNRR) and 2022 (revised DTI) and approved. The paper clarifies, using standard European tools, and using the case of DTI and its link with PNRR, the missed connections were essentially due to weak decisions, lack of methodology, and skilled people that put on risk the plans. The discussion doesn't seek political implications and mistakes, it's only an explanation of the risks due to the failure of technical skills and foresees implementation risks into the definition phase of the plans. The paper results in a suggestion for reformulation of the whole strategy and plan management process and new tools in Italian central and local public administration.The paper tries to clarify the gap between strategic management and plan management.

OS DESAFIOS LOGÍSTICOS E AS TENDÊNCIAS EM RELAÇÃO AO CHAMADO E-COMMERCE
The work deals with the main challenges of urban logistics, being the place where most people live and the center of commercial exchanges in the national territory. The text intends to point the attention to the studies of the logistics in relation to the territory and the geographic variables of the urban and metropolitan areas. There are new challenges for logistics in urban areas and they were discussed in this work as elements of theoretical and methodological reflection: e-commerce and city logistics. The objective of the research is to show the approaches and the relevant characteristics of the spatial dimensions and their relations so that they are discussed and incorporated as a permanent basis in basic logistics studies. The elements that add value in the analysis were the knowledge of the flows of the movement of the goods, the use of the soil and the relations between real and virtual places in the cities, in order to find a strategy for the management of the set of the primary activities (transport, stock and warehouse) and more efficient complementaries for each place, considering the high cost of existing opportunities in the metropolises.
Keywords: e-commerce, urban logistics, urban transportO trabalho trata dos principais desafios da logística urbana, sendo o lugar onde mora a maioria das pessoas e o centro das trocas comerciais no território nacional. O texto pretende apontar a atenção aos estudos da logística em relação ao território e as variáveis geográficas das áreas urbanas e metropolitanas. Há novos desafios da logística nas áreas urbanas e eles foram discutidos nesse trabalho como elementos de reflexão teórica e metodológica: e-commerce e city logistics. O objetivo da pesquisa é mostrar as abordagens e as características relevantes das dimensões espaciais e suas relações para que sejam discutidas e incorporadas como base permanente nos estudos básicos de logística. Os elementos que agregam valor na análise foram o conhecimento dos fluxos do movimento das mercadorias, o uso do solo e as relações entre lugares reais e virtuais nas cidades, de modo a encontrar uma estratégia para a gestão do conjunto das atividades primárias (transporte, estoque e armazém) e complementares mais eficientes para cada lugar, considerando o alto custo de oportunidades existentes nas metrópoles
Complexity planning comparative approaches
Planning complexity is an underestimated process that uses poor tools and was little discussed as a method in the project management literature. The more complex the human organization the more problems are all over the process. Tools, methods, and theoretical understanding of a complexity plan needed to be evaluated as a whole and they must encompass all human organization and environmental change aspects. The paper explains the theory and the reference tools and, as a result, suggests developing strategies and cooperative decision-making tools before starting planning complexity. The more complex the plan the more stakeholders are needed to decide and cooperate with the planners. It is fallacious to try to shortcut the process needs using digitalization or other cost-saving tools with an expectation of being more efficient. As the complex plan is not easy to define and forecast, the entropy of the system is reached only raising energy or costs to manage all the problems that spread up when the plan starts. It is not a problem of inefficiency and a cause-effect process.Planning complexity is an underestimated process that uses poor tools and was little discussed as a method in the project management literature.

Most numbers are not normal
We show, from a topological viewpoint, that most numbers are not normal in a
strong sense. More precisely, the set of numbers with the
following property is comeager: for all integers and , the
sequence of vectors made by the frequencies of all possibile strings of length
in the -adic representation of has a maximal subset of accumulation
points, and each of them is the limit of a subsequence with an index set of
nonzero asymptotic density.
This extends and provides a streamlined proof of the main result given by
Olsen in [Math. Proc. Cambridge Philos. Soc. 137 (2004), 43--53]. We provide
analogues in the context of analytic P-ideals and regular matrices
Concerning three classes of non-Diophantine arithmetics
We present three classes of abstract prearithmetics, , , and . The first one is weakly projective with respect to the conventional
nonnegative real Diophantine arithmetic
, while the other two
are weakly projective with respect to the conventional real Diophantine
arithmetic . In addition,
we have that every and every are a complete
totally ordered semiring, while every is not. We show that
the weak projection of any series in converges in
, for any , and that the weak projection of any
non-oscillating series in converges in , for
any , and in , for all . We also
prove that working in and in , for any , allows to overcome a version of the paradox of the heap, while working
in does not
Roteiro de transferência de tecnologia para pequenas empresas: bases teóricas
The paper seeks to explain the importance of technology transfer for small firms. The technology transfer plan fits inside the Technology Plan of the Business Plan. Some suggestions give the framework for small firms to process a strategy and avoid failure in the technology cycle. The paper has a didactical purpose and uses bibliographic research to give the pieces of information and the logic of the process. The result is to inform and clarify its importance in a Business Plan somewhere missed in the general education and standard templates, but that is important for small firms to cure
A retomada do uso do espaço geográfico no discurso Europeu e do Brasil no planejamento estratégico do território - uma introdução
O planejamento Europeu do território, na mudança de paradigmas, devidos ao
desenvolvimento histórico da sociedade e das instituições, está desenvolvendo uma nova
interpretação retórica, um novo discurso e um novo uso do conceito do espaço. No presente
trabalho se apresenta uma explicação e uma contextualização desse tema em três partes. A primeira
fala do conceito do espaço e sua importância na Geografia. A segunda explica como na Europa está
reativado este conceito á luz da história do planejamento territorial dos últimos anos. Uma terceira
parte conclusiva coloca as possibilidades futuras em assumir este novo discurso na discussão
metodológica na geografia e no conceito de planejamento no Brasil.
