The iterative development process is a framework used to design products and applications across a wide range of domains. It centers around building prototypes, testing them, and updating based on the test results. We discuss how we applied this technique to create Fractal Emergence, an interactive piece of mathematical art.

Over the years ethical, social and environmental accounting (ESEA) has become a common practice among responsible organisations. ESEA entails assessing and reporting organisations" performance on environmental, social and governance topics. In this report, we present a textual grammar for specifying ESEA methods. With the grammar ESEA models can be created. Such models can be interpreted by our open-source, model-driven tool, called openESEA. The report presents the metamodel of the grammar, the grammar itself, and explanations of each grammar primitive.

A prototype of Loongson IoT (Internet of Things) ZigBee gateway is already designed and implemented. However, this prototype is not perfect enough because of the lack of a number of functions. And a lot of things should be done to improve this prototype, such as adding widely used IEEE 802.11 function, using a fully open source ZigBee protocol stack to get rid of proprietary implement or using a fully open source embedded operating system to support 6LoWPAN, and implementing multiple interfaces.

Vagueness is a linguistic phenomenon as well as a property of physical objects. Fuzzy set theory is a mathematical model of vagueness that has been used to define vague models of computation. The prominent model of vague computation is the fuzzy Turing machine. This conceptual computing device gives an idea of what computing under vagueness means, nevertheless, it is not the most natural model. Based on the properties of this and other models of vague computing, it is aimed to formulate a basis for a philosophy of a theory of fuzzy computation.

We present version two of the Latex graphical style file Axodraw. It has a number of new drawing primitives and many extra options, and it can now work with \program{pdflatex} to directly produce output in PDF file format (but with the aid of an auxiliary program).

The perspective we take on a system determines the features and properties of this system that we are focusing on. It determines where we search for causes to explain the effects on the system that we observe. It determines the terms in which we expect the information about the system to be expressed. And it can also influence the choice of formalism that will be used to convey the information. using Boolean Automata Networks as prototypes of interaction systems, this paper means to start making these considerations concrete in order to draw a practical benefit out of them.

This paper proposes an improved variable step-size (VSS) scheme for zero-point attracting projection (ZAP) algorithm. The proposed VSS is proportional to the sparseness difference between filter coefficients and the true impulse response. Meanwhile, it works for both sparse and non-sparse system identification, and simulation results demonstrate that the proposed algorithm could provide both faster convergence rate and better tracking ability than previous ones.

This study demonstrates that incorrect data are entered into a pairwise comparisons matrix for processing into weights for the data collected by a rating scale. Unprocessed rating scale data lead to a paradox. A solution to it, based on normalization, is proposed. This is an essential correction for virtually all pairwise comparisons methods using rating scales. The illustration of the relative error currently, taking place, is discussed.

This paper presents an original domotic embedded system for room temperature monitoring. The OpenRemote is the main software interface between the user and the system, but other software components and communication protocols are used, such as 1-Wire protocol for temperature monitoring devices, RS-232 for the central PC unit and OWFS software for remote control using Android mobile devices. The system architecture consists in hardware and software components to remote control a room temperature parameter for energy efficiency increasing.

A hybrid docking simulator is a hardware-in-the-loop (HIL) simulator that includes a hardware element within a numerical simulation loop. One of the goals of performing a HIL simulation at the European Proximity Operation Simulator (EPOS) is the verification and validation of the docking phase in an on-orbit servicing mission.....

In the present paper, we discuss a method to design a linear phase 1-dimensional Infinite Impulse Response (IIR) filter using orthogonal polynomials. The filter is designed using a set of object functions. These object functions are realized using a set of orthogonal polynomials. The method includes placement of zeros and poles in such a way that the amplitude characteristics are not changed while we change the phase characteristics of the resulting IIR filter.

We conducted surveys before and after the 2012 U.S. Presidential election and prior to the NY City Mayoral election in 2013. The surveys were done using Amazon Turk. This poster describes the results of our analysis of the surveys and predicts the winner of the NY City Mayoral Election.

The present work consists of designing a Single Balanced Mixer(SBM) with the 65 nm CMOS technology, this for a 1.9 GHz RF channel, dedicated to wireless applications. This paper shows; the polarization chosen for this structure, models of evaluating parameters of the mixer, then simulation of the circuit in 65nm CMOS technology and comparison with previously treated. Keywords: SBM Mixer, Radio Frequency, 65 nm CMOS Technology, Non-Linearity, Power Consumption.

Pharma frauds are on the rise, counterfeit drugs are giving sleepless nights to patients, pharmaceutical companies and governments. The laws prohibiting the sales of counterfeit drugs cannot succeed without technological interventions. Several analytical techniques and tools including spectroscopy, holograms, barcoding, differentiated packing, radio frequency identification, fingerprints, hyperspectral imaging etc. have been employed over the years in combating this menace; however this challenge is becoming more sophisticated with the evolution of the World Wide Web and online pharmacies. This paper presents a review on the contribution of Information and Communication Technology (ICT) as a drug counterfeit countermeasure.

Automatic assessment needs short answer based evaluation and automated assessment. Various techniques used are Ontology, Semantic similarity matching and Statistical methods. An automatic short answer assessment system is attempted in this paper. Through experiments performed on a data set, we show that the semantic ASAGS outperforms methods based on simple lexical matching; resulting is up to 59 percent with respect to the traditional vector-based similarity metric.

This paper is the first in series of four papers that present an analytical approach to war using game theory. We try to explore why is it that "true peace" can't be achieved and all or any efforts we make towards that goal will have huge road-blocks. A fairly simplistic and non technical overview of our approach is given in this paper using prisoner's dilemma.

Thermal functional circuits are an interesting and perspectivic group of the MEMS elements. A practical realization is called Quadratic Transfer Characteristic (QTC) element which driving principle is the Seebeck-effect. In this paper we present the analyses of a QTC element from different perspectives. To check the real behavior of the device, we measured a few, secondary properties of the structure which correspond to special behavior because these properties can not be easily derived from the main characteristics.

This paper presents a reduced-order model for the Reynolds equation for deformable structure and large displacements. It is based on the model established in [11] which is piece-wise linearized using two different methods. The advantages and drawbacks of each method are pointed out. The pull-in time of a microswitch is determined and compared to experimental and other simulation data.

Can there be independent higher level laws of nature if everything is reducible to the fundamental laws of physics? The computer science notion of level of abstraction explains why there can -- illustrating how computational thinking can solve one of philosophy's most vexing problems.
