Motivational drivers of customer brand engagement and its effect on share of wallet in a social media context

2014

In recent years, many companies have used social media as part of their marketing and brand building activities. The rise of social media has strengthened the need for customer activation and engagement. Customer brand engagement offers companies multiple positive outcomes, such as satisfaction, trust, loyalty, and empowerment, which potentially facilitate successful business performance. The idea of engagement is relatively new in the marketing literature, and academic research has only minimally examined the potential for growth presented by engaging customers. However, numerous researchers have recognized the growing academic interest in customer brand engagement, as evidenced by the Mar…

Optical sensor for remote estimation of alcohol concentration in blood stream

2013

Abstract The purpose of this manuscript is to validate our recently developed novel optical approach for extraction of remote vibration sources as a successful technique to estimate the alcohol concentration in blood stream. This technique is based on the tracking of temporal changes of reflected secondary speckle patterns produced in human skin when being illuminated by a laser beam. Since the skin’s vibrations profile is changed due to the alcohol in the blood stream, the extraction of the vibration profile can be translated into the corresponding alcohol concentration values by means of defining several parameters acting as indicators for the presence of alcohol in the blood stream. We h…

Computer Simulation for the Study of CNC Feed Drives Dynamic Behavior and Accuracy

2007

In the application of CNC feed drives it is desirable to predict the servo performance. By using computer simulation techniques it is possible to construct an accurate model of the servo drive. This simulation procedure makes it possible to anticipate machine design problems and correct them. This paper deals with a model of a feed drive, which consists of a motion control system driven by a DC motor. Both position and velocity feedback loops are present in the structure of the system. By means of MATLAB & Simulink software, simulation diagrams were built in order to test the behaviour of the system. Experimental data are also presented in order to confirm the accuracy of the theoretical mo…

IMPROVING CNC MACHINE TOOLS ACCURACY USING MODELING AND COMPUTER SIMULATION TECHNIQUES

2007

Abstract The position was one of the first parameters that required the introduction of automatic control process. One of the most representative applications is represented by the feed drives of the computer numerically controlled (CNC) machine tools. Today, it is possible to use computer simulation techniques in analysing and synthesising position control systems. Thus, the behaviour of the CNC machine tools feed drives can be treated much more realistically. It is the purpose of this paper to show how simulation can be used to accurately represent, predict and improve the performance of a CNC machine tool feed servo drives.

A Qualitative-Quantitative Approach to V-Belt Mechanics

1996

A simplified formulation is adopted for the theoretical problem of tension distribution and radial penetration of a V-belt along the pulley groove. The trajectory portrait of the second order differential system describing the belt behavior is carefully analyzed and asymptotic approximations for the tension solutions are derived which are well suited for design purposes.

A hardware skin-segmentation IP for vision based smart ADAS through an FPGA prototyping

2017

International audience; In this paper we presents a platform based design approach for fast HW/SW embedded smart Advanced Driver Assistant System (ADAS) design and prototyping. Then, we share our experience in designing and prototyping a HW/SW vision based smart embedded system as an ADAS that helps to increase the safety of car's drivers. We present a physical prototype of the vision ADAS based on a Zynq FPGA. The system detects the fatigue state of the driver by monitoring the eyes closure and generates a real-time alert. A new HW/SW codesign skin segmentation step to locate the eyes/face is proposed. Our presented new approach migrates the skin segmentation step from processing system (S…

A dynamic simulation approach to frame drivers and implications of corruption practices on firm performance

2014

Corruption is a multifaceted socio-economic phenomenon widely spread - although with different intensity - all around the world. Many studies on corruption have been conducted at a country-level, but relatively little effort has been placed in evaluating its implications, in terms of both financial and competitive performance, at a firm-level. Therefore, this paper aims at exploring the causal relationships underlying the effect of corruption on firm performance in order to show the different scenarios that may emerge from the combination between external (i.e., contextual conditions) and internal (i.e., organizational characteristics) forces that drive corruption. To this end, we adopt a D…

DEMAND DRIVEN SUPPLY CHAIN ED INNOVAZIONE: IL SISTEMA LOGISTICO-PRODUTTIVO PER LA SODDISFAZIONE DEI BISOGNI DEL CLIENTE

2008

La produzione di beni e servizi, per il soddisfacimento dei bisogni, con il oiettarsi nel tempo e nello spazio, determina incertezza e rischi in vario odo correlati a due diversi aspetti: uno di carattere tecnico inerente la ma della capacità produttiva di cui disporre, l’altro di natura più icamente economica, dovuto al fatto che i bisogni, che le produzioni sono stinate a soddisfare, si proiettano nel futuro con caratteri di significativa utabilità e variabilità2 . Anche se l’impresa dedica rilevanti risorse per la evisione della domanda, al fine di allinearla con l’offerta, non sempre iene i risultati attesi. Nonostante i cospicui investimenti, i sistemi di evisione non riescono infatti …
