Abstract:

The purpose of this paper is to share the findings on the typical problems facing the heritage

or old buildings in term of the problem of building leakage scenario in Malaysia. From the

problem finding, the paper tabulate a list of potential solutions best practiced by the local

waterproofing implementer. It is important for the reader to take advantage on the

information of the extensive list of the real case studies pertaining to the building leakage

syndrome typically happened for heritage structure in this hot and humid tropical climate. The

good thing about this paper is that all the case studies are derived from the real selected

projects done by the associated building maintenance contractor for the last 20 years. By

identifying the possible factors that cause the leakage, one can take early steps to prevent the

same defects form repeating thus saves a lot of money! From the finding analysis, this paper

also giving the formulation ideas that can be use for creating a framework to prevent or

minimize the building leakage syndrome from happening again. As the old buildings or the

buildings that old enough to be considered worth to keep are becoming more valuable to

either the central Government or the local council; the analysis from this paper may give some

meaningful tabulation on how to maintain these heritage buildings from leakage especially

from the roof seepage thus make the property much more valuable to the owner and may give

profit to the locality as well.

Abstract— The behaviour of Concrete-Filled Steel Tube (CFST) beam strengthened with

Carbon Fibre Reinforced Polymer (CFRP) sheet was investigated numerically in this paper.

Nonlinear analysis using ABAQUS Finite Element (FE) software to assess the behaviour of

square and circular CFST beams wrapped from bottom side with U-shaped of CFRP sheet

using different length and multi layers. The FE models were verified accurately through

successful comparison with existing experimental study done by others. The results

obtained from the study show that various lengths and multiple layers of CFRP sheets

directly affect the ultimate moment capacity of CFST beams; where the ultimate moment

capacity of the CFST beams was improved by increasing the layers of CFRP sheets -

specifically for beams - wrapped along 75% or more of their length. Meanwhile, CFRP

delamination failure has been observed for beams wrapped along 50% of their length,

where delamination failure occurred earlier with an increasing number of CFRP layers.

Moreover, by increasing the wrapping length of CFRP sheet to more than 75% of the beam’s

length did not lead to further improvement in the beam’s moment capacity for each specific

number of CFRP layers.

tubular membrane under different process parameter. Carbonization is the most important

step in the fabrication of carbon membrane and can be recognized as the heart of the carbon

membrane production. The preparation and characterization of carbon membranes originated

from Matrimid were studied. Matrimid-based carbon tubular membrane will be fabricates and

characterize in terms of its gas permeation properties. The carbonization temperature during

the carbon membrane fabrication was studied. The polymer solution was coated on the

surface of tubular ceramic tubes by using dip-coating method. The polymer tubular membrane

was then carbonized under Argon atmosphere at different carbonization temperature; 600,

750, and 850 ◦C. Pure gas permeation tests were performed using CH4 and CO2 at room

temperature with pressure 8 bars. Based on the results, the highest CO2/CH4 selectivity of

87.30 was obtained for carbon membrane prepared at 850 oC.

Abstract—This paper deals with power quality improvement of a Z-source inverter fed wind

power generation system, using hybrid active power filter. The Z-source inverter is used as

power electronic interface for voltage and frequency control. However, it introduces higher

order harmonics into the system; the use of non-linear load also has inherent problem of poor

power quality. To overcome the problems of harmonics and reactive power hybrid active

power filter is introduced between system and load. The proposed wind power generation

system is modeled in MATLAB / Simulink environment. Improved performance of the system

after inclusion of hybrid active power filter is demonstrated through comparison on various

indices like THD, reactive power compensation, power factor etc.

Index Terms—Wind power generation system, Z-source inverter, Power quality, hybrid active

ABSTRACT

Wood plastic composite (WPC) is a panel or lumber product made from recycled plastic and

small wood particles or fibers. Such products are widely used in the USA for many applications

including decking, roof tiles, playground equipment, picnic tables, fencing rails, window

lineals and automotive components. The objective of this work was to evaluate some

properties of experimental wood plastic composite (WPC) samples manufactured with nano-

clay added Eastern redcedar (Juniperus virginiana L.) particles. Three percent and six percent

nano-clay was added to 40 percent wood particles and 60 percent high density polyethylene

(HDPE). One percent maleic anhydride polypropylene, as coupling agent, was added to a pre-

mixture of 40% wood and 60 % (HDPE). Subsequently, this mixture was added with nanoclay

up to 6% by weight, and casted into WPC samples by injection molding. The samples were

characterized for tensile strength, elastic modulus, water absorption, thickness swelling, and

surface roughness. Additionally, the binding of wood and polymer was elucidated by infrared

spectroscopy and the microstructure was studied by electron microscopy. A slight decrease in

tensile strength and elastic modulus has been found with increasing clay content, which is

explained by limited dispersion of the nanoclay as well as partial coverage of the wood

particles with nanoclay during the mixing processes. Clay content in the samples enhanced

their dimensional stability. Based on the findings in this work it appears that Eastern redcedar

as an underutilized species would have potential to be used as raw material to manufactured

value-added wood composite products.

Candida sp. is the most widely studied pathogenic fungi. The infections caused by them are

collectively known as candidiasis. They are root cause of a number of medical conditions like

oral thrush, vulvovaginal candiadiasis, perianal candidiasis, esophageal candidiasis and a

number of other conditions in people with weak immune system. Current antifungal arsenals

are becoming a major cause of resistance against candida species. Hence there is an urgent

need to find new compounds with antifungal activity. Piperazine is an ethylenediamine

derivative or cyclic ethylenediamine (cyclizines). In the search of better antifungal agent the

antifungal properties of Piperazine were checked in this study against C. albicans, C.

dubliniensis. Minimum inhibitory concentration (MIC) of Piperazine against different starin of

candida was 256-512 µg/ml. Agar Plate Dilution Test, filter disc assay and Microdilution Test

were performed to explore more about the antifungal activity of Piperazine. Study further

indicated that piperazine nucleus is a versatile and medicinally important nuclei having

promising antifungal potential which may provide lead compounds for drug design and

development of potent antifungal agents. The valuable information extracted in this study may

help in the development of Piperazine as potent antifungal agent in future and could provide

an effective antifungal therapy to the patients suffering from fatal microbial infections.

ABSTRACT

Biotechnological production of pyruvic acid is recently receiving much attention owing to its

cost effectiveness and sustainability. Reactive extraction is a promising approach that can be

applied for in-situ recovery of pyruvic acid from the fermentation media. Nevertheless,

efficiency, selectivity and biocompatibility of the solvent system are the key issues still to be

resolved. Solvent toxicity can be minimised by the use of non toxic natural diluents.

In the present work reactive extraction of pyruvic acid (0.1 to 0.5 kmol∙m-3) has been studied

using tributylamine (TBA; 10 to 30%) as an extractant dissolved in non toxic rice bran oil at

T=30 ±1 ℃. Results were presented in terms of distribution ratio, extraction efficiency, loading

ratio and complexation constant. Extraction equilibrium was modelled and compared using

different modelling approach.

The proximate composition of waste products derived from sugarcane (Sacharum officinarum)

and soy bean (Glycine max) were determined. Further, the present study was undertaken to

evaluate two waste materials, as low-cost substrates to grow Lactobacillus sp. through

fermentation. The proximate analysis was conducted and the extent of variation in water

content, protein, lipid, ash and fibre and carbohydrate content of both wastes were studied.

The results obtained show that the water content of soy whey and bagasse was 96.71 and

61.20%, respectively. The dry matter in the products of soy whey and bagasse estimated was

3.29 and 38.08%, respectively. The protein continent of soy whey and bagasse was 0.72 ± 0.02

and 0.45 ± 0.01, respectively. Soy whey possesses lipid (0.06 ± 0.02%), ash (0.54 ± 0.09%) and

fiber (1.01 ± 0.05%), while bagasse waste contains lipid (0.18 ± 0.04), ash (0.82 ± 0.08%) and

fiber (11.34 ±0.54%). Finally, carbohydrate content was 0.96 and 26.01% from soy whey and

bagasse, respectively. Gross energy of soy whey shows low calorie (11.3 kcal/100g) compared

with bagasse (83.5 kcal/100g). The results of nutritional analysis suggest that soy whey and

bagasse wastes products could be the cheapest and valuable bio-resource to grow probiotics.

ABSTRACT- Agarwood tree is one of source resin production and known as fragrant wood that

have a highly valuable product in the global market. However, the process of hydrodistillation

efficiency is far from sufficient and affecting to the lower product quality and oil yield. Two

important purposes of this research are to investigate five pre-treatment techniques and to

identify the effective extraction method tested by standard hydrodistillation and re-design

hydrodistillation. Two other parameters which are different sample sizes (0.5cm, 0.75cm and

1.0cm) and shaking times (1,3 and 7 days) that affect on oil yield were studied. The oil

produced was compared with industrial samples. The results indicated that the optimum

parameter prior extraction is from sample size 0.5cm, soaked with fungi Phanerochaete

Chrysosporium and shaken for 7 days. Redesign hydrodistillation coupled with stirrer gave a

higher oil yield than the extraction by standard hydrodistillation. The chemical components of

the agarwood oil were analyzed by using Gas Chromatography with Flame Ionization Detector

(GC-FID) and Gas chromatography with Mass Spectrometry (GC-MS).

ABSTRACT

Among the debilitating diseases, cardiovascular related diseases are the most challenging ones

to be treated using cell replacement therapies. Recently, human exfoliated deciduous teeth

(SHED) and adipose stem cells (ASC) were suggested as alternative cell choice for cardiac

regeneration. However, the truly functionability of these cells toward cardiac regeneration is

yet to be discovered. Hence, this study was carried out to investigate the innate biological

properties of these cell sources toward cardiac regeneration. Both cells exhibited

indistinguishable MSCs characteristics. Human stem cell transcription factor arrays were used

to screen expression levels in SHED and ASC. Up-regulated expression of transcription factor

(TF) genes was detected in both sources. An almost equal percentage of > 2-fold changes were

observed. These TF genes fall under several cardiovascular categories with higher expression

were observed in growth and development of blood vessel, angiogenesis and vasculogenesis

categories. Further induction into cardiomyocyte revealed ASC to express more significantly

cardiomyocyte specific markers compared to SHED during the differentiation course

evidenced by morphology and gene expression profile. Despite this, spontaneous cellular

beating was not detected in both cell lines. Taken together, our data suggest that despite being

defined as MSCs, both ASC and SHED behave differently when they were cultured in a same

cardiomyocytes culture condition. Hence, a vigorous characterization is needed before

introducing any cells for treating targeted diseases.

Abstract

There is much concern regarding the human health effect of potassium bromated

(KBrO3). Therefore, this substance is prohibited in Saudi Arabia.. Samples from five

well-known brands, locally produced, potato chips and crisps. The samples have

shown relatively high levels of bromate, which raises concerns about channels and

mechanisms of bromate access to these foodstuffs. This requires more studies and

investigations in this direction. Potassium bromate was estimated in the samples by

determination of the total bromine (Br) using ICP-MS.

Splendour of the global warming issue and the environmental concern is discussed intensively in

this century. Many research contributed effectively to overcome the problems. One of the

important issues regarding the environment problem in the world is demolishing plastic waste.

Demands of practical and consumptive lifestyle has encouraged increasing used of plastic each

year. Thus, it is important to develop a user friendly plastic but having competitive strength with a

conventional plastic. Modified Thermoplastic Starch (TPS) is prepared from local resource Sago

which is available abundantly in Indonesia and does not have a proper value. Polyurethane

Prepolymer (PUP) was synthesized and mixed reactively with sago in situ in an intensive mixer to

prepare modified TPS. The variations of PUP in the TPS have influent the characteristic of the

modified TPS produced. Several tests have shown forming mechanism and characteristic of

modified TPS such as Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and

tensile test. PUP and sago matrix was cross link through urethane linkage and found out to be

compatible together with tight and dense phase. PU Micro particles acted as an impact modifier for

the modified TPS and consequently improved the toughness of TPS. TPS 3 has higher tensile test

with reasonable elongation at break and water absorption.

Abstract—The corrosion behavior of lead free tin based solder alloys such as Sn97.0Ag3.0,

Sn98.5Ag1.0Cu0.5 and Sn96.5Ag3.0Cu0.5 was investigated in 3.5% NaCl solution. Scanning electron

microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) were

used to characterize the samples after the electrochemical tests. Potentiodynamic polarization

curves showed that the addition of copper with Sn-3Ag solder alloy exhibited better corrosion

resistance while lowering the Ag content decreased the resistance. The presence of tin

oxyhydroxychlorides was detected at the surface of solder alloy after polarization tests. The better

corrosion resistance of Sn96.5Ag3.0Cu0.5 solder alloy could be ascribed to the formation of

compact and adherent corrosion product on the metal surface.

Key words—Corrosion resistance, Pb-free solder alloys, potentiodynamic polarization.

Abstract— Software process tailoring is one of the solutions to customise existing software

development process to be used in the new software project. Current practice in the software

process tailoring usually adopts an ad hoc approach that tends to use directly the old process

from the previous project or process that is familiar to the software development team. Value-

based software engineering concept brings the benefit of maximising the value contribution in

the software project (e.g. budget, schedule and stakeholder satisfaction) as compared to

conventional software development approach that aims only for the success of project

completion. This study is trying to integrate the value-based factors into the software process

tailoring framework. The aim of this paper is to describe the methodology that will be

employed in order to produce a conceptual framework of value-based software process

tailoring. Prior to develop the conceptual framework, results from the systematic literature

review, industry survey and expert review are vital as input to the framework. The core

components of the conceptual framework are value-based factors, project characteristics,

process elements and tailoring rationale.

Keywords— software process tailoring, value-based software engineering, framework,

Abstract: Yogyakarta is a tourism city with increasing number of tourists. This result to the area

surrounds points of interest turning into business and trade area. The growing business and trade

sector induces the tendency to use signage for advertisement. The problem is, the existence of that

many signages somehow have covered up the face of Yogyakarta as a cultural heritage. There are so

many occurrences of misused signage, varied from misplaced signage to installing unauthorized

signage. Furthermore, another problem occurs from the visual aspect of the city, because signage

instalment affects the aesthetic of the street corridors. Therefore, a research in field of organizing

signage must be conducted based on visual aspect. This research is aimed to create an organized

design of signage that is appropriate according to visual aspects (colour, form, line, texture, and

scale). This research is using descriptive analysis method in the form of policy analysis and

evaluative analysis through Visual Impact Assessment. The result of this study is formed as how

much the signage impacts visual aspect and then developed into an input for creating signage

organizing design and adapted to the policy.

Keywords: Signage, Street Corridor, Visual Impact Assessment.

developing idea and prototype.

3D printing offers engineers highly effective ways and cost saving method to produce

prototype. In this paper, fast prototype is produced using 3D Printer model Makerbot

Replicator 2. The Printer software uses STL file to translate from CAD software to the 3D

Printer. Prototype can be produced within a one hours or more depending of the size and

numbers of models.

This paper aimed to study the process and approaches of implementation of designing

prototype using 3D printers. It will lead the revolution of adapting 3D printer into our

future.

Architecture, Music and Pattern Recognition

The Case of Andalusian Architecture

Abstract—The aim of this ongoing research project is to reach a pattern recognition process

(design system) that can turn architecture to music, and turn music to architecture. . In both

operations, style and character will be an essential issue in the design of this process system.

Based on the artistic relationship between architecture and music, we shall try to settle a

mechanism for a pattern recognition audio-visual system that can that can turn a certain style

of architecture to a collection of melodies that truly reflects the character of that architecture.

This system can also perform the the inverted process, that is turning a certain musical style to

a collection of shapes and forms. In this regard it is important to point out to the inter-

relationship between the architectural design process and writing a musical note. A musician

composing a melody works from above, that is from the whole to the parts. A composer does

not usually put notes together in order to get some melody; he envisages the character of a

melody in a statu nascendi and proceeds from above as he tries to concretize it in all its part. In

this respect, the articulation of the whole and the important junctures of the parts, the

beginning(s), or the end(s), the composer accepted the attitude of his contemporaries, and

could therefore integrate principles of architecture such as the golden section and the

Pythagorean Theorem, along with principles of acoustic harmony.

TOWARDS THE SOCIAL LOGIC OF SPACES IN THRISSUR,INDIA:

Understanding the influence of culture on spatial organisation of traditional urban

cores of India

Ar.Josna Raphael.P, Associate Professor, School of Architecture, Government Engineering College, Thrissur,

Kerala, India .

Abstract

Space syntax is a set of techniques for the representation, quantification, and interpretation of spatial

configuration in buildings and settlements. Existing studies using the Space Syntax methodology

have compared cities, from different regions of the world, based on their configurational properties

and have shown that while organic cities across the world follow various generic characteristics

there are variations within them due to cultural differences. This paper sets out to explain the

structural organisation of space and the distribution of religious, commercial and residential land

uses within Thrissur, a South Indian temple city, using the configurational approach.The study

identifies culture specific human preferences about space proxemics. The research has been fostered

by questions: (1) How to understand and quantify the spatial configurations of organically evolved

built environments of urban cores in Indian cities? (2) Based on the configuration parameters, can

one understand the human aspects in terms of user preferences about the space proxemics, in the

Indian context. The analysis of selected examples shows some similarity in terms of syntactic

identity. The placement of important religious, administrative or commercial urban activity nodes, in

Abstract: Determination of the hydrodynamic pressure acting on dams during earthquake has

been of high interest in design steps of these structures. An efficient method for the analysis of

forced vibration of the dam and reservoir in different modes of the dam's motion and deformation

has been presented which, could be easily extended to study fluid-structure interaction. The SBFEM

(Scaled Boundary Finite Element Method) is utilized to model the far-field sub-domain while the

FEM (Finite Element Method) is used to model the near-field sub-domain of the reservoir. Although

a simple geometry of boundary conditions has been chosen, all the required necessities to extend the

method to a practical case are implemented.

Abstract—The ICT market is growing rapidly and more business and social networking

systems is crossing over to less developed regions. This IT usage expansion is associated with

increasing environmental threats in the form of greenhouse effects and hardly decommissioned e-

waste. For this reason sustainable development became an issue in the last two decades of the 20th

century. Recently, sustainable software engineering has become a hot research topic; it spans

sustainability aspects in all stages of software lifecycle. This paper discusses sustainability issues in

the human-interaction design phase, and it suggests appropriate steps which would lead to tackle

HCI sustainability issues such as lower power consumption, waste and saving the wellbeing of

human users.

Abstract - Nowadays, we are working in a stimulating scenario where the new digital technologies

and the traditional design process in Architecture are definitively mixed together. We know that

majority of mistakes in the phase of construction comes from the design phase and this trend looks

often to come from a base concept aimed to separate, dramatically, the design activity from the

construction activity. The most negative effects were detected in terms of increasing costs and of

decreasing of the quality of the buildings. The new computational methodologies can enable us to

obtain significant benefits in reducing the gap between designing and building. The new parametric

approaches can help to highlight the centrality of the constructive detail. The concept of parameter

is, at the same time, logical element and material element; therefore its nature is related to the theory

and also to the practice of the Architecture. If we think to the importance of the executive detail, the

parametric approach looks like the link between the "bit" and the brick. It is necessary designing the

building, according its constructive logic: that is possible only trying to develop a biunique link

between the two phases of the process that must be conceived as only one. To think via parametric

the constructive details, means knowing that any existing design complexity can be lead back to an

original constructive element: this dynamic discloses the sense of the complexity. I think that the

digital fabrication represents the first real “bridge” between design and construction, because

transforms a digital component in real component. The new technical and cognitive paradigms can

be an efficient contribution in order to define a theoretical and practical vision in order to understand

"the design of the construction" and "the construction of the design" as one. The next step of that

current research will be how to move our vision from the “Architecture as ontology” to the

“Architecture as taxonomy”.
