Benford' law: a number -theoretical perspective
The historical journey of the Benford’s law and its most important definitions and properties are shortly reviewed. Firstly, we define a new class of numbers based on the first-digit law. Secondly, we investigate the relation between Benford’s sequence and normal numbers
A geometric characterization of ves and kadiyala-type production functions
The basic concepts of the differential geometry are shortly reviewed and applied to the study of VES production function in the spirit of the works of Vîlcu and collaborators. A similar characterization is given for a more general production function, namely the Kadiyala production function, in the case of developable surfaces
NOTES ON A CONFORMAL CHARACTERIZATION OF 2-DIMENSIONAL LORENTZIAN MANIFOLDS WITH CONSTANT RICCI SCALAR CURVATURE
We present a characterization of 2-dimensional Lorentzian manifolds with con-stant Ricci scalar curvature. It is well known that every 2-dimensional Lorentzian manifolds is conformally flat, so we rewrite the Ricci scalar curvature in terms of the conformal factor and we study the solutions of the corresponding differential equations. Several remarkable examples are provided
Exact solutions for a Solow-Swan model with non-constant returns to scale
The Solow-Swan model is shortly reviewed from a mathematical point of view. By considering non-constant returns to scale, we obtain a general solution strategy. We then compute the exact solution for the Cobb-Douglas production function, for both the classical model and the von Bertalanffy model. Numerical results are eventually provided
Application-Aware Power Capping Using Nornir
Power consumption of IT infrastructure is a major concern for data centre operators. Since data centres power supply is usually dimensioned for an average-case scenario, uncorrelated and simultaneous power spikes in multiple servers could lead to catastrophic effects such as power outages. To avoid such situations, power capping solutions are usually put in place by data centre operators, to control power consumption of individual server and to avoid the datacenter exceeding safe operational limits. However, most power capping solutions rely on Dynamic Voltage and Frequency Scaling (DVFS), which is not always able to guarantee the power cap specified by the user, especially for low power budget values. In this work, we propose a power-capping algorithm that uses a combination of DVFS and Thread Packing. We implement this algorithm in the Nornir framework and we validate it on some real applications by comparing it to the Intel RAPL power capping algorithm and another state of the art power capping algorithm
Transparent Autonomicity for OpenMP Applications
One of the key needs of an autonomic computing system is the ability to monitor the application performance with minimal intrusiveness and performance overhead. Several solutions have been proposed, differing in terms of effort required by the application programmers to add autonomic capabilities to their applications. In this work we extend the Nornir autonomic framework, allowing it to transparently monitor OpenMP applications thanks to the novel OpenMP Tools (OMPT) API. By using this interface, we are able to transparently transfer performance monitoring information from the application to the Nornir framework. This does not require any manual intervention by the programmer, which can seamlessly control an already existing application, enforcing any performance and/or power consumption requirement. We evaluate our approach on some real applications from the PARSEC and NAS benchmarks, showing that our solution introduces a negligible performance overhead, while being able to correctly control applications’ performance and power consumption
Il marketing dei sensi : cinque sensi per vendere e comprare
Immagini, odori, suoni, materiali, sapori studiati per raggiungere il pubblico obiettivo e per indurlo a determinate azioni. Questo e non solo è il marketing dei sensi, un approccio sempre più diffuso nei diversi settori del mercato, dove spuntano sale d'attesa pervase da profumi, reparti dei supermercati in cui si respirano odori irresistibili, negozi che sembrano set cinematografici, brani composti per osannare un prodotto. Vista, udito, tatto, gusto, olfatto sono i canali per conoscere la realtà, per comunicare al 100% e per vivere da consumatori consapevoli. Nel libro sono trattate le tecniche più evolute per conquistare il mercato, tutti i segreti delle vendite e delle marche vincenti. Il testo affronta anche temi discussi e delicati come la comunicazione subliminale. Scritto per tutti quelli che vogliono esplorare il marketing sensoriale e la comunicazione emozionale, per i professionisti e per chi vuole avere il ruolo di consumatore attivo. Un testo ricco di esempi realizzato da tre esperti del settore che hanno voluto condividere le loro esperienze sul marketing dei sensi
