Ciclo PDCA e ferramentas da qualidade em operações e serviços de e-commerce

The market has forced companies to maintain high levels of control over their processes , ensuring a product or service quality to its customers . This study comes in the issuance and registration carried out in a company of e-commerce , which is showing problems with the values of weights and dimensions used in the cases cited . The need to eliminate wasteful spending freight caused by shipment of products weighing more than the reality, and to increase the reliability of the information used in the management of processes led to the planning of this project . This work focuses on the development of a PDCA cycle to work in the identification and correction of the causes of the problem , in order to neutralize the current complications and ensure that the problem does not appear again. To aid the mapping of the processes involved , identifying the causes of the problem and implementation of the proposed improvements were used quality tools such as flowcharts , Ishikawa diagrams , Pareto diagrams , and applied statistics

Estudo do comportamento reológico de sucos combinados de frutas vermelhas

The aim of this work was to evaluate the rheological behavior of combined juices of strawberry, blackberry and raspberry in two different temperatures of interest in industrial processes in the food industry, using rheological analyses on non-oscillatory regime and the Response Surface Methodology (RSM). The rheological data were fitted by the Casson model. All samples of combined juices of ref fruits showed a Newtonian behavior and the rheological parameters yield stress (Kc) and plastic viscosity of Casson (Koc) had a decrease in its values with the temperature increase. By the analysis of the ternary diagrams it is evident that the raspberry juice effectively contributed to the higher values of yield stress and plastic viscosity of Casson in both temperatures studied.

Ontopolíticas e diagramas históricos do poder: maioria e minoria segundo Deleuze e a teoria das multidões segundo Peirce

This article aims at developing the so-called ontopolitics as G. Deleuze s innovative contribution to contemporary political philosophy. This objective will lead us to inspect the concept of power that Deleuze borrowed from Foucault and extended in order to assign to it an ontological adequacy. The concept of power opens access to another important element of the Deleuzean political philosophy, that is, the study of the historical diagrams of the power in the so-called discipline and control societies. With the combined dynamical diagram of both, we become aware of the portrait Deleuze draws for the democracy in contemporary societies. Digging into the Deleuzean ontopolitics, we will devote ourselves to the concepts of majority, minority and minor-becoming. It is in this point that the meeting between Deleuze s ontoplitics and Ch. Sanders Peirce s mathematical ontology becomes sound. It happens that Deleuze s ontopolitical concepts, besides their bond to an ontology of the power, receive also a mathematical treatment related to certain arithmetical (denumerable and nondenumerable) and geometrical notions (lines). The majorities and minorities are denumerable sets which are crossed by nondenumerable becomings. This step done, we will reach the stand point of the present paper, where we carry out initial approach with regard to an image for the concepts of majority and minority on the basis of Peirce s theory of collections and multitudes, mostly envisaging the mathematical ontology included in it. Accordingly, the main operation to be accomplished is that the Deleuzean distinction between the denumerable majorities/minorities and the nondenumerable mino-becoming may be mapped out in terms of discrete collections called enumerable, denumerable and abnumerable or postnumerable, in compliance with Peirce s terminology.

Surface coverage in wireless sensor networks based on delaunay tetrahedralization

In this work is presented a new method for sensor deployment on 3D surfaces. The method was structured on different steps. The first one aimed discretizes the relief of interest with Delaunay algorithm. The tetrahedra and relative values (spatial coordinates of each vertex and faces) were input to construction of 3D Voronoi diagram. Each circumcenter was calculated as a candidate position for a sensor node: the corresponding circular coverage area was calculated based on a radius r. The r value can be adjusted to simulate different kinds of sensors. The Dijkstra algorithm and a selection method were applied to eliminate candidate positions with overlapped coverage areas or beyond of surface of interest. Performance evaluations measures were defined using coverage area and communication as criteria. The results were relevant, once the mean coverage rate achieved on three different surfaces were among 91% and 100%.

Effect of temperature on salt-salt aqueous biphasic systems: manifestations of upper critical solution temperature

Water-miscible ionic liquids (ILs) may be salted out using kosmotropic salts such as potassium phosphate (K3PO4) to form salt-salt aqueous biphasic systems (ABS). The effect of temperature on these systems has been studied using phase diagrams and it is observed that the degree of binodal shift decreases (requiring lower IL and kosmotropic salt concentrations) with the increase of temperature following the trend [C(4)mim]Cl > [C(4)py]Cl > [C(4)mmim] Cl > [N-4444]Cl. This trend can be correlated with the decreasing hydrogen bonding abilities of each salt. The phase behavior was also interpreted on the basis of critical solution temperature behavior of pure aqueous ionic liquid solutions. Additionally, the distribution of alcohols in these systems was studied as a function of temperature and it was found that the distribution ratios did not change with changes in temperature. The Gibbs energy of transfer of a methylene group in these systems and correlation to tie-line length was also determined. It was concluded that while the miscibility of alcohols increases in the ILs with increasing temperature, phase divergence in the aqueous biphasic system decreases, and thus these competing forces tend to cancel each other out for small polar molecules. A comparison is provided for the response to temperature in the currently studied salt-salt systems and analogous ABS formed by the addition of hydrophilic polymers to kosmotropic salts (polymer-salt) or other polymers (polymer-polymer).
