Functions are an important component in the study of mathematics (NCTM 1989, 2000). Learning about the concept of functions can be a natural way for students to “mathematize” the real-world relationships that they observe. Everyday life abounds with opportunities for students to observe and describe dynamic relationships that can be classified as functions.

Development And Validation

The hardware in the loop technologies allow to simulate physical models in combination with real devices in order to validate the behavior of the latter under different conditions, not easily reproducible in the real world. They are widely used in various industrial applications. In this work we want to extend the methodology to medical devices. These must interact with the patient to obtain the desired clinical result, however, during the development and validation phase of medical devices, the patient cannot be involved in the testing process. In this article the hardware in the loop methodology is proposed starting from a mathematical model of the heart, based on oscillators, that can be used to validate pacemakers or other medical devices.

Service Rates

Waiting lines or queues are commonly occurred both in everyday life and in a variety of business and industrial situations. The various arrival rates, service rates and processing times of jobs/tasks usually assumed are exact. However, the real world is complex and the complexity is due to the uncertainty. The queuing theory by using vague environment is described in this paper. To illustrate, the approach analytical results for M/M/1/8 and M/M/s/8 systems are presented. It optimizes queuing models such that the arrival rate and service rate are vague numbers. This paper results a new approach for queuing models in the vague environment that it can be more effective than deterministic queuing models. A numerical example is illustrated to check the validity of the proposed method.

Abstract The traditional approach to inflation as a tax does not take any account of the state of indexation of the economy, as if universal «implicit» indexation of individual incomes to inflation by adjustment of inflationary expectations prevailed. This article shows that if - as is the case in much of the real world today - explicit indexation through wage escalator clauses and the like is sufficiently widespread but does not cover all individuals in the economy, then it may become feasible and attractive for a coalition of voters to pass inflationary budgets. Since budget choices and the determination of the associated inflation tax are outcomes of a collective (political) decision process while indexation is privately negotiated in the market, indexed voters may try to make non-indexed voters pay the bill of budget benefits to themselves through the inflation tax. Inflation thus becomes a peculiar, negative public good with a private exit: the inflation tax can now be individually avoided through indexation, and a demand for inflation in the literal meaning can manifest itself through the electoral process. Various properties of this perverse budget-inflation game are discussed, showing that the only natural way out of it appears to be universal indexation, which would eliminate the incentive to free-riding behavior by the indexed voters, though at some transitional cost to society.

The Real

Critics of null hypothesis significance testing suggest that (a) its basic logic is invalid and (b) it addresses a question that is of no interest. In contrast to (a), I argue that the underlying logic of hypothesis testing is actually extremely straightforward and compelling. To substantiate that, I present examples showing that hypothesis testing logic is routinely used in everyday life. These same examples also refute (b) by showing circumstances in which the logic of hypothesis testing addresses a question of prime interest. Null hypothesis significance testing may sometimes be misunderstood or misapplied, but these problems should be addressed by improved education.

Ubiquitous Presence

Though there is much to gain through technological development, it is also necessary to critique the ubiquitous presence of devices in social life and the overstimulation they bring. The increasing mediation of reality through applications such as Instagram could blur the division between the ‘real’ world of everyday life and a ‘hyperreality’ fostered by such applications. Using concepts from theorists Jean Baudrillard and Georg Simmel, this paper presents a critique of the overstimulation of information through social media. With continuous and repetitive material being recycled online, it is discussed how a blasé attitude is used to protect oneself from being informationally overwhelmed.

Robot Task

The application of robots to variable tasks in unstructured environments presents a series of problems that must be solved in order to achieve viable results Common teaching-type robots cannot be applied in these cases as the programming time and labor investment far exceed the time and cost of direct manual production. Numerically controlled (NC) robots programmed off-line by modified NC methods have been applied with economic success to program robots directly from computer-aided design (CAD) data where tasks are sufficiently repetitive and the operating environment is sufficiently structured Similarly, off-line programming systems have been developed by various robot manufacturers to generate instructions from CAD data for their robots. Likewise, developers of 3D simulation software have devised methods to merge CAD data with physical models of robots and system hardware to produce robot path programs that approximate the tasks to be performed. Each of these systems is unable to provide a totally automated means to program robot tasks directly from CAD data due to inaccuracies in the real-world elements and/or the models, and due to a lack of knowledge about the processes. A new approach to automatic robot programming is needed that is capable of dealing with:inherent differences between the CAD models and the real-world parts;uncertainties regarding the precise location and accessibility of the parts relative to the robot:process knowledge required to adapt these differences and uncertainties; andprocess knowledge essential to optimizing robot activities. Such an automatic robot programming system is being developed to meet the dual-use defense and commercial ship construction needs of American shipyards under the Technology Reinvestment Project (TRP) for Shipbuilding Robotics. This system automates the programmer's task of identifying location of welds, assigning weld process parameters and adaptive welding strategies to each joint. A procedural diagram for this system is shown in Figure 1. The results and benefits of this approach are described herein. Fig. 1Procedure for automatic off-line robot task planning

Different Cultures

In our everyday life, as we work or travel, we are always confronted with many kinds of borders: political ones when we travel to other countries, or cultural ones, when we meet people with different backgrounds or lifestyles. We generally take these borders as something natural or let alone as something sacrosanct. And although in the Western civilization, we are aware of the fact that we have big difficulties in accepting the other‘s point of view or her way of life, we rather reinforce the borders and isolate ourselves from influences alien for our traditional or so-called pristine world. How could people of different cultures, religions, or languages manage to live together in the most harmonic way possible? Music is one kind of art which inspires and unites people across borders, but so does imagination: The Aletic Republic as a fictional republic transcends a world from imagination into a tangible place full of persons, landscapes, stories, poetry, and moods.

Unique Method

The real world of everyday life with its unfailing routines, repetitions and manifold habits may be seen as a matrix for the immanent expressions of what could holistically be called ‘The Void’, ‘The Real’ or simply ‘The all-embracing presence of immanence’. Thus, everyday life situations may tell us more than we normally assume about ourselves and the chimerical vision of an existing subject within the process of self-expression. But how can we investigate such situations in an appropriate manner, so that they show us by themselves somehow pre-reflexive patterns they incorporate? There is no unique method of how to investigate such situations; however, there should be a methodological form of performative settings beyond the stage which I would like to discuss.Following some of the ideas of Julian Klein and Arno Böhler on the significance of our feelings and on the limits of conceptual thinking I propose a specific form of philosophical performances, which is based on a grounding of emotions within thinking and on postponed deliberations within networking groups of individuals who are sharing a similar background of specific experiences in a given population.

Scarcely anything influences today’s young generation as intensely as global and digital developments. Confusing real places in everyday life and virtual places in online communities leads to an acting out of their hybrid identity in the context of globalisation. These new opportunities consequently create new, often ambivalent, forms of identity in adolescents. Thus the boundaries between the virtual and the real world coalesce, the two can no longer be separated. What significance does spirituality have for this generation? How can youth ministry react? This article aims to link the intersection of globalisation, digital networks and virtual reality with the spirituality of adolescents, and to find out what a contextualisation of a Christian youth ministry could look like in these intersections.
