Usage of the symbols and Dionis square in the cryptosystem of Dionis
The rapid developments of technology which have brought with them a host of benefits to humanity have also left behind a host of spaces which have mostly aided cyber piracy who exploit the many benefits of the internet for purposes that are in their favor,but these actions which negatively affect the privacy of all internet users. In this project I will present some modifications which are enabled through the 16x16 square of Dionis with 256 elements based in the Masonic Cipher method, with the help of which based on the rules I have created and developed it is different from all the others that have been presented so far containing some specific specifications within it, in order to make the possibility of decryption as difficult as possible for the abusers, but understandable to implement
Una ruta matemĂ tica al meu poble, Onda
Treball Final de Grau en Mestre o Mestra d'Educació Primà ria. Codi: MP1040. Curs acadèmic: 2016/2017Aquest TFG té com a objectiu apropar les Rutes Matemà tiques a les escoles d’educació primà ria.
En aquest cas, es tracta d’una proposta didà ctica dirigida als cursos de 5è i 6è del col·legi Baltasar
Rull Villar d’Onda.
El fi de les Rutes MatemĂ tiques Ă©s aconseguir que els alumnes puguin comprovar que el seu
voltant està rodejat d’elements matemà tics i que les matemà tiques no queden contextualitzades
solament a l’escola. A partir d’aquesta realitat, els alumnes descobreixen l’oportunitat de qüestions
i problemes matemĂ tics que sorgeixen de la seva vida quotidiana i voltant.
Per tant, en aquesta proposta trobarem un possible camĂ per a treballar les rutes amb els
xiquets/es. Una introducció al concepte per a 5è i una posada en prà ctica per a 6è.
En aquestes farem un viatge d’observació al poble d’Onda i un reconeixement al patrimoni històric.
L’objectiu fonamental és que els alumnes aprenguin i gaudeixin al mateix temps.
Donada la limitació d’extensió del TFG, trobarem als annexos la proposta introductòria per a 5è

Rupture
I am an interdisciplinary artist working in painting, photography, printmaking, sculpture, video and installation. I employ these mediums to create a coming of age story as a Dominican New Yorker, exploring masculinity, vulnerability, the supernatural, family, and religion, as well as how culture plays a role in my community and in my life
Using Heavy Quark Fragmentation into Heavy Hadrons to Determine QCD Parameters and Test Heavy Quark Symmetry
We present a detailed analysis of the use of heavy quark fragmentation into heavy hadrons for testing the heavy quark effective theory through comparison of the measured fragmentation parameters of the c and b quarks. Our analysis is entirely model independent. We interpret the known perturbative evolution in a way useful for exploiting heavy quark symmetry at low energy. We first show consistency with perturbative QCD scaling for measurements done solely with c quarks. We then apply the perturbative analysis and the heavy quark expansion to relate measurements from ARGUS and LEP. We place bounds on a nonperturbative quark mass suppressed parameter, and compare the values for the b and c quarks. We find consistency with the heavy quark expansion but fairly sizable QCD uncertainties. We also suggest that one might reduce the systematic uncertainty in the result by not extrapolating to low z
Time-optimal control of two-level quantum systems by piecewise constant pulses
We apply an extension of the Pontryagin Maximum Principle to derive
time-optimal controls of two-level quantum systems by means of piecewise
constant pulses. Global optimal solutions are obtained for state-to-state
transfer in the cases with one and two controls. Exact quantum speed limits are
established as a function of the sampling period. We observe numerically an
exponential convergence towards the minimum time in the continuous limit when
this period goes to zero. We show that this convergence is only polynomial for
a linearized quantum system. We discuss the experimental impact of this result.Comment: 28 pages, 9 figure
Allylic Cations in Solvolysis. A Case of Non-Participation
The rate constants and secondary deuterium Isotope ef\u27fects
are measured in the solvo\u27lysis of various allyHc p-nitrobenzoates.
The obtained results are explained by differences in inductive
effects o>f vardous groups in the side-chain. These results
are in keeping with the stepwise mechanism according to which
neighboiring group n- and n-paxticiipation is not revealed in the
studied solvCJ!lytic reactions
Winterstrom mit alpiner Photovoltaik : Messergebnisse nach zwei Jahren Versuchsbetrieb
Die alpine Testanlage in Davos Totalp lieferte 2018 und 2019 jeweils bis zu 2000 kWh/kWp bei circa 50 % Winterstromanteil. Dies entspricht gegenĂĽber einer Vergleichsanlage im Mittelland einem Mehrertrag von 100 % ĂĽber das gesamte Jahr und 350 % im Winterhalbjahr
