Published: July 2018

The utilization of vibration energy harvesters as a substitute to batteries in wireless sensors has shown prominent interest in the literature. Various approaches have been adapted in the energy harvesters to competently harvest vibrational energy over a wider spectrum of frequencies with optimize power output.   A typical bistable piezoelectric energy harvester, where the influence of magnetic field is induced into a linear piezoelectric cantilever, is designed and analyzed in this paper. The exploitations of the magnetic force specifically creates nonlinear response and bistability in the energy harvester that extends the operational frequency spectrum for optimize performance.  Further analysis on the effects of axial spacing displacement between two repulsive magnets of the harvester, in terms of x-axis (horizontal) and z-axis (vertical) on its natural resonant frequency and performance based on the frequency response curve are investigated for realizing optimal power output. Experimental results show that by selecting the optimal axial spacing displacement, the vibration energy harvester can be designed to produce maximized output power in an improved broadband of frequency spectrum.

Robust RAM Control for WSR on the Water Surface
Authors: Chun K , Kim B
Published: July 2018

This paper discusses a robust rotate and move (RAM) controller by considering a water striding robot (WSR) with two wheels. The proposed controller commands the WSR to rotate and move straight toward the desired target by considering the two wheel WSR characteristics. Sliding mode control (SMC) is one of the solutions in nonlinear controller design and it has fast response and robustness. SMC is applied to the WSR RAM control. However, the sliding mode has a problem called chattering because of using sign function in controller design and this will cause the system unstable in WSR control because the chattering make the WSR sink into water easily. As a solution, sign function is replaced by saturation function. The proposed controller is noble and track the target point easily and also has robustness. The stability of the proposed controller is proved by Lyapunov function and the simulation results show the fast response and robustness.

Published: July 2018

In software development life cycle, testing plays the significant role to verify requirement specification, analysis, design, coding and to estimate the reliability of software system. A test manager can write a set of test cases manually for the smaller software systems. However, for the extensive software system, normally the size of test suite is large, and the test suite is prone to an error committed like omissions of important test cases, duplication of some test cases and contradicting test cases etc. When test cases are generated automatically by a tool in an intelligent way, test errors can be eliminated. In addition, it is even possible to reduce the size of test suite and thereby to decrease the cost & time of software testing.It is a challenging job to reduce test suite size. When there are interacting inputs of Software under Test (SUT), combinatorial testing is highly essential to ensure higher reliability from 72 % to 91 % or even more than that. A meta-heuristic algorithm like Particle Swarm Optimization (PSO) solves optimization problem of automated combinatorial test case generation. Many authors have contributed in the field of combinatorial test case generation using PSO algorithms.We have reviewed some important research papers on automated test case generation for combinatorial testing using PSO. This paper provides a critical review of use of PSO and its variants for solving the classical optimization problem of automatic test case generation for conducting combinatorial testing.

Published: July 2018

To date, repair of damaged columns has become increasingly more significant. The failure of columns structure contributes to the serious consequences in structural stability. Most of the existing repairing techniques are based on lateral passive confining pressure. However, this passive-type of confinement is ineffective in restoring the performance of damaged concrete columns. In this regards, active confinement was selected in this study to repair damaged concrete columns which can actively confine concrete in this study. Steel strapping tensioning technique (SSTT) allows pre-tensioning low-cost recycled steel straps around the damaged column was chosen herein to represent active confinement. A total of 12 columns were prepared and loaded axially to certain degree of their respective ultimate strength. Hence, a pre-damage level of the columns was developed. Then, the damaged columns repaired by using mortar and confined with SSTT. Finally, the repaired columns were then tested under monotonic uniaxial load. The structural performances of the confined repaired columns were compared with those of the repaired columns without confinement. It is expected that as the concrete compressive strength increases, the effectiveness in restoring the load carrying capacity of the damaged column becomes more significant.

Published: July 2018

Information on the influences of native plant species and rainfall characteristics on the stormwater retention performance of extensive green roofs in Malaysia is still scarce. More local data is still required because rainfall and runoff generation processes in tropical environment are very different from the temperate regions. This study is aimed to investigate the stormwater retention performance of native plant species in extensive green roofs with respect to different rainfall characteristics in Malaysia. Two test beds consist of pro-mixing potting soil were vegetated each with different native plant species (Axonopus Compressus (cow grass), Portulaca Grandiflora (sedum) and one test bed with no vegetation (bare ground) was prepared as a control. A total of 22 significant storm events were collected over a 3-month period from March 2016 to May 2016. The rainfall depths for monitored storm events were ranged from 4.5 mm to 63.2 mm and rainfall intensities ranged from 0.5mm/hr to 58.5 mm/hr. The results showed that sedum exhibited higher mean runoff retention percentage than grass which is 75.8% and 70.9%, respectively. Bare soil was the least effective for reducing water runoff with retention percentage of 62.6%. Overall, sedum and grass species provided 90.6% and 88.2% of cumulative rainfall retention in this study. The rainfall depth and intensity are correlated negatively with stormwater retention performance of green roofs. Meanwhile, longer dry weather period are likely to increase the water retention capacity of green roof.

The project concentrates on the basic design of a cooling system for rapidly cooling nylon 6, 6 polymer fibers using cold air. The ambient air after pre-treatment in the air-washer is available at 72°F all year round. Based on the company’s throughput, it is required to supply (quench) air at 58°F. Nylon 6, 6 polymer after thorough polymerization is distributed through 16 quench cabinets and each quench cabinet requires approximately 530 ft3/min (cubic feet per minute, CFM) of air. The project concentrates on the basic design of a cooling system wherein air at the required mass flow rate is supplied at 58°F for the quenching process. A basic design of the refrigeration cycle and heat exchangers were considered in this work. In the development of the basic design for heat exchanger, performance charts were developed. Performance charts describe the performance of the heat exchanger in terms of fundamental dimensionless parameters. Using performance charts it was clearly seen that increasing the number of transfer units (NTU) doesn’t necessarily increase the rate of heat transfer. Increasing the NTU beyond an optimum value is pointless and increases the capital cost of the heat exchanger. The preliminary design involves selection of appropriate NTU and capacity rate ratio for the heat exchanger. From the capacity rate ratio and NTU, it is fairly straight forward to extrapolate the detailed design for the heat exchanger. A cooling system model was developed for the design process and for the simulation of the cooling system.

Natural ventilation of building provides improvement of internal comfort and air quality conditions leading to a significant reduction of cool-ing energy consumption. Design of natural ventilation systems for many types of building is based on buoyancy forces. However, external wind flow can have significant effects on buoyancy- driven natural ventilation. The paper was concerned with transient investigation of airflow through two vents in the absence of opposing flow in the upper opening. A flow of this type represents a new class of boundary- layer flow problems in the building. Moreover, this is an exact solution of the complete Navier- Stokes Equations (including, buoyancy force term), which were then Non Dimensionalised using some dimensionless parameters and then solved analytically by separation of variable methods in which, the behavior of parameters in the results were predicts the velocity, temperature profiles together with volumetric airflow and mass transfer. The results were then evaluated numerically for several sets of values of the parameters in order to ascertain the best for optimal ventilation.

Urban planners and architects have used different design criteria by following project processes different from each other through the ages. The common point of all these projects has been functionality which is one of the most important criteria for human based design. Aesthetics, beauty and similar terms may be arguable but a non-functional spatial design must not be accepted. All spaces, cities, squares, parks, roads and buildings are designed for people. If these urban structures are not suitable for them, people will have serious problems in terms of general circulation. Therefore, ergonomics and functionality terms must be the basic design criteria of all human based urban planning and architectural design processes. How may it be possible to understand an urban design project or a building is functional before constructing it? The aim of this article is to explain the benefits of pedestrian simulation technologies through the design processes in both theoretical and practical frameworks on a case study area which is an underground metro station. A capacity analysis and circulation assessment has been carried out on the metro station by using Massmotion pedestrian simulation software. Extended English summary is in the end of Full Text PDF (TURKISH) file.ÖzetGeçmişten günümüze şehir planlama ve mimarlık alanında gerçekleştirilen çalışmalarda çeşitli tasarım kriterleri kullanılmış, birbirinden farklı planlama süreçleri izlenmiştir. İnsanların kullanımına yönelik gerçekleştirilen hemen hemen tüm çalışmaların en önemli ortak noktası ise ‘kullanışlılık’ olmuştur. Estetik, güzellik ve benzeri göreceli kavramlar tartışılabilir olmakla birlikte, insanların kullanımı için tasarlanan bir yapının fonksiyonel olmaması inşa sonrasında ciddi bir sorun teşkil edecektir. Planlanan kentler, meydanlar, yollar, yapılar kullanışlı olmadığı takdirde kullanıcılar sirkülasyon anlamında sıkıntılar yaşayacaklardır. Bu nedenle gerçekleştirilen tüm şehir planlama ve mimarlık çalışmalarında hem ergonomi hem de kullanışlılık konusuna çok dikkat edilmesi gerekmektedir. Peki, kentsel tasarımı yapılan bir proje alanının ya da mimarlar tarafından tasarlanan bir yapının fonksiyonel olup olmadığı daha inşa edilmeden nasıl anlaşılabilir? Bu çalışmanın amacı, son yıllarda gelişen yaya simülasyonu teknolojilerinin mimarlık ve planlama alanındaki projelerin tasarım değerlendirme süreçlerinde kullanımının yararlarını hem teorik açıdan ortaya koymak hem de gerçekleştirilen örnek bir uygulama üzerinde göstermektir. Çalışma kapsamında bir metro istasyonuna ilişkin mimari çizimler üzerinden kapasite analizi gerçekleştirilmiş, sirkülasyon açısından değerlendirme yapılmıştır. Yaya simülasyonu kapsamında gerekli analizlerin gerçekleştirilmesi amacıyla Massmotion yazılımı kullanılmıştır.

Artykuł, oparty na dotychczasowych analizach, wykorzystuje teoretyczny dyskurs komparatystycznej imagologii, by pokazać jej produktywne aspekty na materiale będącym przykładem stosunku polityki i literatury. Wybrano przede wszystkim utwory, które były istotnymi wydarzeniami w rozwoju literatury słowackiej i pozwalają na jej odniesienie do kontekstu literatury Europy Środkowej od lat czterdziestych XX wieku. W artykule zwrócono uwagę również na inne symptomy: dwa etapy podziemia literackiego, emigrację wewnętrzną, niezależność wewnętrzną, kilka typów auto-obrazów i ich występowania lub oddziaływania w strukturze dziela literackiego. Artykuł dotyczy jednego z typów słowackiej twórczości literackiej i dąży do odideologizowania obrazu słowackiej literatury jako literatury typu wiejskiego.
