Misuse of pre-exponential factor in the kinetic and thermodynamic studies using thermogravimetric analysis and its implications
Authors: Ali Imtiaz
Published: July 2018

This paper describes the misuse of Arrhenius pre-exponential factor in the kinetic and thermodynamic studies using thermogravimetry. Standard test method (ASTM E698) has been used recently by many researchers to calculate the pre-exponential factor. ASTM E698 is reserved for differential scanning calorimetry (DSC) and impose many restrictions which have being overlooked by many recently. The obtained pre-exponential factors have been used to describe the thermodynamic behavior during the course of thermal conversions. The objective of this paper is to inform the readers that the pre-exponential factor obtained from the restricted equation can mislead and generate some false thermodynamic data.

Authors: Iannuzzi Mariano , Barnoush Afrooz , Johnsen Roy
Published: July 2018

The ever-growing energy demand requires the exploration and the safe, profitable exploitation of unconventional reserves. The extreme environments of some of these unique prospects challenge the boundaries of traditional engineering alloys as well as our understanding of the underlying degradation mechanisms that could lead to a failure. Despite their complexity, high-pressure and high-temperature, deep- and ultra-deep, pre-salt, and Arctic reservoirs represent the most important source of innovation regarding materials technology, design methodologies, and corrosion control strategies.This paper provides an overview of trends in materials and corrosion research and development, with focus on subsea production but applicable to the entire industry. Emphasis is given to environmentally assisted cracking of high strength alloys and advanced characterization techniques based on in situ electrochemical nanoindentation and cantilever bending testing for the study of microstructure-environment interactions.

Authors: Vosoughi Payam , Karein Mahmoud Motahari , Kazemian Ali , Tavakol Sasan , Ramezanianpour Ali A.
Published: July 2018

In this paper Artificial Neural Networks (ANNs) are employed to develop a model which could estimate the RCPT value of various mixtures according to the mix design parameters, age and surface resistivity of concrete specimens. Furthermore, sensitivity analysis is carried out on the best ANN model to determine the influence of each input on the concrete resistance to the rapid chloride penetration. 258 experimental datasets, resulted from 79 mix designs, were used as training data for ANN models; all of which prepared and tested in Concrete Technology and Durability Research Center of Amirkabir University of Technology (CTDRC). Another simplified model is proposed using linear regression analysis; which estimates the RCPT value simply according to surface resistivity measure. Finally, eight mixtures prepared in Building and Housing Research Center (BHRC) and six mixtures obtained from real-life projects, are employed to compare and validate the proposed models.
Enhancement of Shear Transfer in Composite Deck with Mechanical Fasteners
Authors: McComb Christopher , Tehrani Fariborz
Published: July 2018

Reinforced concrete construction and steel construction are two of the most common contemporary construction methods. Both methods make use of composite decks as floor systems and diaphragms. During the design of composite decks, the interaction between the steel deck and concrete slab is typically disregarded when calculating the strength of the composite di- aphragm due to lack of complete shear transfer, as existing practices such as stamping are not effective to provide substantial composite action. This conservative assumption essentially results in non-efficient use of material. This paper presents a method for ensuring shear transfer through the use of conventional sheet metal screws, driven through the corrugated steel deck and embedded in the fresh concrete. This method is proposed for use in the field between formed steel beams. Both experimental and analytical stud- ies support an increase in strength with the addition of embedded fasteners. Further, experimental results indicate an additional increase in strength with the addition of synthetic reinforcing fibers. The increase in strength with the addition of the fasteners is on the order of 100%. When fasteners are already in use, the addition of synthetic reinforcing fibers can increase strength on the order of 10%. The ultimate deflection of enhanced deck is comparable to deck tested without fasteners, but the initial stiffness of enhanced deck is much higher.
Adaptive Plant Propagation Algorithm for Solving Economic Load Dispatch Problem
Authors: Nag Sayan
Published: July 2018

Optimization problems in design engineering are complex by nature, often because of the involvement of critical objective functions accompanied by a number of rigid constraints associated with the products involved. One such problem is Economic Load Dispatch (ED) problem which focuses on the optimization of the fuel cost while satisfying some system constraints. Classical optimization algorithms are not sufficient and also inefficient for the ED problem involving highly nonlinear, and non-convex functions both in the objective and in the constraints. This led to the development of metaheuristic optimization approaches which can solve the ED problem almost efficiently. This paper presents a novel robust plant intelligence based Adaptive Plant Propagation Algorithm (APPA) which is used to solve the classical ED problem. The application of the proposed method to the 3-generator and 6-generator systems shows the efficiency and robustness of the proposed algorithm. A comparative study with another state-of-the-art algorithm (APSO) demonstrates the quality of the solution achieved by the proposed method along with the convergence characteristics of the proposed approach.
REDUCING STRUCTURAL ERROR IN FUNCTION GENERATING MECHANISMS VIA THE ADDITION OF LARGE NUMBERS OF FOUR-BAR MECHANISMS
Authors: Hessein
Published: July 2018

This paper presents a methodology for synthesizing planarlinkages to approximate any prescribed periodic function. Themechanisms selected for this task are the slider-crank and thegeared five-bar with connecting rod and sliding output (GFBS),where any number of drag-link (or double crank) four-bars areused as drivers. A slider-crank mechanism, when comparing theinput crank rotation to the output slider displacement, producesa sinusoid-like function. Instead of directly driving the inputcrank, a drag-link four-bar may be added that drives the crankfrom its output via a rigid connection between the two. Drivingthe input of the added four-bar results in a function that is lesssinusoid-like. This process can be continued through the additionof more drag-link mechanisms to the device, slowly alteringthe curve toward any periodic function with a single maximum.For periodic functions with multiple maxima, a GFBS is usedas the terminal linkage added to the chain of drag-link mechanisms.The synthesis process starts by analyzing one period ofthe function to design either the terminal slider-crank or terminalGFBS. A randomized local search is then conducted as thefour-bars are added to minimize the structural error between thedesired function and the input-output function of the mechanism.Mechanisms have been “grown” in this fashion to dozens of linksthat are capable of closely producing functions with a variety ofintriguing features.

Published: July 2018

Water-lifting technologies for irrigation have significant potential to increase agricultural yields and stimulate economic growth in rural areas of the developing world. Human-powered water pumps have been used with great success in this rapidly developing market. KickStart's MoneyMaker Hip Pump is a human-powered water pump with additional design features that make it lightweight and portable for use in remote fields in several countries throughout Africa. This work first applied numerical optimization techniques to the design of the MoneyMaker Hip Pump and offers further improvements to its design. Deterministic multi-objective optimization methods were employed to maximize the flow rate of the pump, maximize the pumping height of water, and minimize cost. Following optimization, the robustness of the optimized pump design was analyzed under several modified scenarios, including fouling of the hoses and a decrease in operator power due to fatigue or aging. The set of cost-optimized pump designs was then compared to a second set of optimal designs that was found using material volume as a simplified proxy for the cost objective function. Findings indicate that several technical improvements can be made to the current MoneyMaker Hip Pump design to reduce cost by up to 37% without affecting water flow rate, or increase water flow rate by up to 88% without increasing cost. The numerical model was validated through physical experimentation of the MoneyMaker Hip Pump, and design alterations to reduce cost were experimentally shown to maintain pump performance.

Published: July 2018

The 2016 is remembered as the year that showed to the world how dangerous distributed Denial of Service attacks can be. Gauge of the disruptiveness of DDoS attacks is the number of bots involved: the bigger the botnet, the more powerful the attack. This character, along with the increasing availability of connected and insecure IoT devices, makes DDoS and IoT the perfect pair for the malware industry. In this paper we present the main idea behind AntibIoTic, a palliative solution to prevent DoS attacks perpetrated through IoT devices.
Effects of Fuel Sulfur Content and Dilution Conditions on Engine PM Emissions under Transient Conditions
Authors: Berg Devin R.
Published: July 2018

The U.S. has introduced ultra low sulfur diesel fuel in 2007 and by 2010 will completely replace the current low-sulfur diesel fuel which has a sulfur content of less than 500 ppm. As a result, most diesel engines, including new and aged ones, are currently implementing ULSD. Thus, it is important to understand how ULSD will affect these engines’ emissions, especially under transient conditions when the load, speed, exhaust gas temperature, and primary dilution ratio change continuously. This study is to assess the effects of fuel sulfur content and aging condition on PM emissions under transient conditions. Combinations of fuels and primary dilutions were used. The primary dilution was accomplished by a CFV-CVS, a system which maintains proportional sampling throughout temperature excursions and is designed for engine emission certification. Data were collected by a Scanning Mobility Particle Sizer and an Engine Exhaust Particle Sizer for steady-state and transient testing, respectively. Although the steady-state results show reasonable agreement with previous studies, the transient results display significant discrepancy when ULSD and LSD were used with the high primary dilution ratio.

Authors: Moerman Kevin Mattheus , Sprengers Andre , Nederveen Aart , Simms Ciaran
Published: July 2018

MRI is an ideal method for non-invasive soft tissue mechanical properties investigation. This requires mechanical excitation of the body’s tissues and measurement of the corresponding boundary conditions such as soft tissue deformation inside the MRI environment. However, this is technically difficult since load application and measurement of boundary conditions requires MRI compatible actuators and sensors. This paper describes a novel MRI compatible computer controlled soft tissue indentor and optical Fibre Brag Grating (FBG) force sensor.

This paper focuses on the fusion of the data acquired from motion and magnetic sensors, i.e., accelerometer, gyroscope and magnetometer sensors, for the recognition of Activities of Daily Living (ADL) using pattern recognition techniques. The system developed in this study includes data acquisition, data processing, data fusion, and artificial intelligence methods. Artificial Neural Networks (ANN) are included in artificial intelligence methods, which are used in this study for the recognition of ADL. The purpose of this study is the creation of a new method using ANN for the identification of ADL, comparing three types of ANN, in order to achieve results with a reliable accuracy. The best accuracy was obtained with Deep Learning, which, after the application of the L2 regularization and normalization techniques on the sensors’ data, reports an accuracy of 89.51%.
Ultimate behaviour of cladding assemblages in industrial buildings
Authors: Málaga-Chuquitaype Christian
Published: July 2018

Profiled steel sheeting is widely used as cladding systems in industrial buildings. These systems are normally composed of thin-walled cold-formed steel profiles attached to steel purlins, or side-rails, which are connected to the column elements by means of simple fastener arrangements. Extensive research has been carried out on the response of cold-formed cladding systems under out of plane loading and codified recommendations are available to estimate their resistance under serviceability and ultimate limit states for the purpose of conventional design verifications. Attention has also been placed recently on quantifying the degree of rotational flexibility offered by purlin-sheeting systems. Nevertheless, the ultimate response of such configurations involves complex interactions within the cladding-purlin-connection assemblage that need to be carefully examined in order to assess and quantify the large deformation response.The study reported in this paper focuses on the inelastic response of industrial cladding systems which are designed and detailed according to conventional European practice. Selected results from a series of quasi-static tests performed within a wider collaborative project aimed at assessing the local and global static and dynamic behaviour of industrial building systems are presented. Due to the comparatively more robust response of typical industrial frame elements, the tests focus on the performance of cladding-purlin-column assemblages. The test layout and boundary conditions are described and the discussion is centred on key structural response parameters, namely stiffness, strength and failure conditions. Preliminary numerical assessments carried out with a view to providing further analytical and design studies are also outlined.

Published: July 2018

The aim of this study was to analyze the accuracy of bone pose estimation based on sub-clusters of three skin-markers characterized by triangular Cosserat point elements (TCPEs) and to evaluate the capability of four instantaneous physical parameters, which can be measured non-invasively in-vivo, to identify the most accurate TCPEs. Moreover, TCPE pose estimations were compared with the estimations of two least squares minimization methods applied to the cluster of all markers, using rigid body (RBLS) and homogeneous deformation (HDLS) assumptions. Analysis was performed on previously collected in-vivo treadmill gait data composed of simultaneous measurements of the gold-standard bone pose by bi-plane fluoroscopy tracking the subjects' knee prosthesis and a stereophotogrammetric system tracking skin-markers affected by soft tissue artifact. Femur orientation and position errors estimated from skin-marker clusters were computed for 18 subjects using clusters of up to 35 markers. Results based on gold-standard data revealed that instantaneous subsets of TCPEs exist which estimate the femur pose with reasonable accuracy (median root mean square error during stance/swing: 1.4/2.8 deg for orientation, 1.5/4.2 mm for position). A non-invasive and instantaneous criteria to select accurate TCPEs for pose estimation (4.8/7.3 deg, 5.8/12.3 mm), was compared with RBLS (4.3/6.6 deg, 6.9/16.6 mm) and HDLS (4.6/7.6 deg, 6.7/12.5 mm). Accounting for homogeneous deformation, using HDLS or selected TCPEs, yielded more accurate position estimations than RBLS method, which, conversely, yielded more accurate orientation estimations. Further investigation is required to devise effective criteria for cluster selection that could represent a significant improvement in bone pose estimation accuracy.
Studying Human Design Teams through Computational Teams of Simulated Annealing Agents
Authors: McComb Christopher , Kotovsky Kenneth , Cagan Jonathan
Published: July 2018

Novel design methodologies are often evaluated through empirical studies involving human designers. However, such empirical studies can incur a high personnel cost. Further, it can be difficult to isolate the effects of specific team or individual characteristics. These limitations could be bypassed by employing a computational model of design teams. This work introduces the Cognitively-Inspired Simulated Annealing Teams (CISAT) modeling framework, an agent-based platform that provides a means for efficiently simulating human design teams. A number of empirically demonstrated cognitive phenomena are modeled within the platform, striking a balance between model simplicity and direct applicability to engineering design problems. This paper discusses the composition of the CISAT modeling framework and demonstrates how it can be used to simulate the performance of human design teams in a cognitive study. Results simulated with CISAT are compared directly to the results derived from human designers. Finally, the CISAT model is also used to investigate the characteristics that were most and least helpful to teams during the cognitive study.

Published: July 2018

All presently available neural stimulation methods are either invasive or can only be moderately localized, and a neurostimulation method that could overcome these limitations would be invaluable for the mapping of brain circuits, disease diagnosis in the brain, neurosurgery and therapy. Neural stimulation with magnetic resonance guided focused ultrasound (MRgFUS) is a promising technology that can noninvasively excite or inhibit neural activity in well-defined discrete volumes of the brain, subsequently enabling investigation of brain circuits with magnetic resonance imaging (MRI). In this study, we seek to explore ultrasonic neuromodulation in the frontal eye field of a macaque monkey, while measuring the effects of neuromodulation via eventrelated potentials, behavioral responses, and blood oxygen level dependent functional MRI.

Sistem Pendukung Keputusan termasuk Fuzzy yang tergolong Fuzzy Multiple Attribute Decision Making (FMADM) adalah suatu metode yang digunakan untuk mencari alternatif optimal dari sejumlah alternatif dengan kriteria tertentu. Inti dari FMADM adalah menentukan nilai bobot untuk setiap atribut, kemudian dilanjutkan dengan proses perankingan yang akan menyeleksi alternatif yang sudah diberikan. Pada dasarnya, ada 3 (tiga) pendekatan untuk mencari nilai bobot atribut, yaitu pendekatan subjektif, pendekatan objektif dan pendekatan integrasi antara subjektif dan objektif. Masing-masing pendekatan memiliki kelebihan dan kelemahan. Pada pendekatan subjektif, nilai bobot ditentukan berdasarkan subjektivitas dari para pengambil keputusan, sehingga beberapa faktor dalam proses perankingan alternatif bias ditentukan secara bebas. Pada pendekatan objektif, nilai bobot dihitung secara matematis sehingga mengabaikan subyektivitas dari pengambil keputusan.

Condensed Matter Physics (CMP) menjadi salah satu cabang fisika yang berkembang dengan sangat cepat. Perkembangan fenomena, konsep, dan teknik semakin bercabang, dan meluas begitu deras, begitu juga dengan diversitasnya. Mungkin masih ada yang merasa kabur dan asingnya makna CMP itu sendiri, apa yang dipelajari, dan tujuannya. Di kelompok garis kanan mungkin ada yang masih meragukan karir dari ilmu CMP ini. Dan dikelompok garis kiri mungkin ada yang mempermasalahkan bahwa CMP terlalu teknis, dan tidak se-teoritis ataupun tidak se-filosofis High Energy Physics(HEP) ataupun kosmologi.Tulisan ini mungkin belum akan dapat menjawab semua penasaran tersebut. Namun saya akan mencoba mengulas tentang CMP itu sendiri—yang berhasil membuat saya banting stir ketertarikan dari HEP dan Kosmologi.Artikel ini akan mendiskusikan tentang hirarki dan paradigma dalam sains, fisika khususnya, dilanjutkan membahas paradigma dan hal yang meng-drive CMP. Lalu akan mengulas emergent phenomena lebih dalam dan konsekuensi terhadap perkembangan teknologi, yang diulas secara historikal, lalu melihat sekilas pengaruh komunitas ilmuwan di bidang ini. Diakhiri akan membahas sedikit tentang bagaimana mempersiapkan diri untuk mempelejari CMP lebih dalam, dan rekomendasi rancangan studi bagi S-1.Tulisan ini jauh dari sempurna, yang hanya ditulis oleh mahasiswa S-1 semester 6 yang sedang menjalani studi formal mengenai CMP. Tulisan ini ditulis atas keinginan dan semangat tinggi untuk memperkenalkan CMP kepada khalayak ramai, dan berbagi ketertarikan. Semoga tulisan ini bisa menjadi inspirasi bagi yang membaca. Jangan biarkan High Energy Physics dan Cosmology merebut semua kesenangan!
