New Results on Subtractive Magic Graphs

For any edge xy in a directed graph, the subtractive edge-weight is the sum of the label of xy and the label of y minus the label of x. Similarly, for any vertex z in a directed graph, the subtractive vertex-weight of z is the sum of the label of z and all edges directed into z and all the labels of edges that are directed away from z. A subtractive magic graph has every subtractive edge and vertex weight equal to some constant k. In this paper, we will discuss variations of subtractive magic labelings on directed graphs

Fuzzy EOQ Model with Trapezoidal and Triangular Functions Using Partial Backorder

EOQ fuzzy model is EOQ model that can estimate the cost from existing information. Using trapezoid fuzzy functions can estimate the costs of existing and trapezoid membership functions has some points that have a value of membership . TR ̃C value results of trapezoid fuzzy will be higher than usual TRC value results of EOQ model . This paper aims to determine the optimal amount of inventory in the company, namely optimal Q and optimal V, using the model of partial backorder will be known optimal Q and V for the optimal number of units each time a message . EOQ model effect on inventory very closely by using EOQ fuzzy model with triangular and trapezoid membership functions with partial backorder. Optimal Q and optimal V values for the optimal fuzzy models will have an increase due to the use of trapezoid and triangular membership functions that have a different value depending on the requirements of each membership function value. Therefore, by using a fuzzy model can solve the company's problems in estimating the costs for the next term

SIMULATING SEISMIC WAVE PROPAGATION IN TWO-DIMENSIONAL MEDIA USING DISCONTINUOUS SPECTRAL ELEMENT METHODS

We introduce a discontinuous spectral element method for simulating seismic wave in 2- dimensional elastic media. The methods combine the flexibility of a discontinuous finite element method with the accuracy of a spectral method. The elastodynamic equations are discretized using high-degree of Lagrange interpolants and integration over an element is accomplished based upon the Gauss-Lobatto-Legendre integration rule. This combination of discretization and integration results in a diagonal mass matrix and the use of discontinuous finite element method makes the calculation can be done locally in each element. Thus, the algorithm is simplified drastically. We validated the results of one-dimensional problem by comparing them with finite-difference time-domain method and exact solution. The comparisons show excellent agreement

Obiter Dicta

"Stitched together over five years of journaling, Obiter Dicta is a commonplace book of freewheeling explorations representing the transcription of a dozen notebooks, since painstakingly reimagined for publication. Organized after Theodor Adorno’s Minima Moralia, this unschooled exercise in aesthetic thought—gleefully dilettantish, oftentimes dangerously close to the epigrammatic—interrogates an array of subject matter (although inescapably circling back to the curiously resemblant histories of Western visual art and instrumental music) through the lens of drive-by speculation. Erick Verran’s approach to philosophical inquiry follows the brute-force literary technique of Jacques Derrida to exhaustively favor the material grammar of a signifier over hand-me-down meaning, juxtaposing outer semblances with their buried systems and our etched-in-stone intuitions about color and illusion, shape and value, with lessons stolen from seemingly unrelatable disciplines. Interlarded with extracts of Ludwig Wittgenstein but also Wallace Stevens, Cormac McCarthy as well as Roland Barthes, this cache of incidental remarks eschews what’s granular for the biggest picture available, leaving below the hyper-specialized fields of academia for a bird’s-eye view of their crop circles. Obiter Dicta is an unapologetic experiment in intellectual dot-connecting that challenges much long-standing wisdom about everything from illuminated manuscripts to Minecraft and the evolution of European music with lyrical brevity; that is, before jumping to the next topic.

Don’t Be Quiet, Start a Riot! Essays on Feminism and Performance

This collection of essays investigates elements of the human voice and performance, and their implications for gender and sexuality. The chapters address affect, pleasure, and memory in the enjoyment of musical and theatrical performance. Rosenberg also examines contemporary feminist performance, anti-racist interventions, activist aesthetics, and political agency especially with regard to feminist and queer interpretations of opera and theatre. She contextualizes her work within broader developments in gender and queer studies, and within the feminist movement by highlighting important contributions of artists who draw from the above to create performance. The book will be welcomed by opera and theatre lovers, students, academics, and the wider public that is interested in the performing arts and its queer feminist potential

Of Cigarettes, High Heels, and Other Interesting Things 3/E

Among species, human beings seem to be a peculiar lot. Why is it, for example, that certain members of the species routinely put their survival at risk by puffing on a small stick of nicotine? Why is it that some females of the species make locomotion difficult for themselves by donning high-heel footwear? Are there hidden or unconscious reasons behind such strange behaviors that seem to be so utterly counter-instinctual, so to speak? For no manifest biological reason, humanity has always searched, and continues to search, for a purpose to its life. Is it this search that has led it to engage in such bizarre behaviors as smoking and wearing high heels? And is it the reason behind humanity’s invention of myths, art, rituals, languages, mathematics, science, and all the other truly remarkable things that set it apart from all other species? Clearly, Homo sapiens appears to be unique in the fact that many of its behaviors are shaped by forces other than the instincts. The discipline that endeavors to understand these forces is known as semiotics. Relatively unknown in comparison to, say, philosophy or psychology, semiotics probes the human condition in its own peculiar way, by unraveling the meanings of the signs that undergird not only the wearing of high-heel shoes, but also the construction of words, paintings, sculptures, and the like
