Traditional engine use carburetor instead of fuel injection. The carburetor uses direct mixing of air and fuel into the engine compare to fuel injection that had a control system that adjust the volume of air to fuel mixture entering the engine. The fuel consumption is depending on the air to fuel ratio that is being injected into engine by injectors. Nowadays the price of the fossil fuel had been increase drastically compared to the last five years. The combustion of the engine has a major impact to the value of the Air-Fuel Ratio (AFR). When the air to fuel ratio is not close to the stoichiometry value, then the fuel consumption is not economical, and the engine is not in their optimum condition. An optimum and economical engine performance give a result in a decrease in fuel consumption thus reducing the carbon monoxide (CO) and hydrocarbon (HC) into the atmosphere. Thus, this paper presents the system identification on fuel control system for controlling the air fuel ratio. Hence the parameters and relationship of the air fuel ratio can be reconnoitering.

The project is on Maximum efficiency of a solar panel. As the sun is not constant at one place and by fixing the solar array at one place, maximum power generation is not possible. This project develops a solar power generation system using maximum power point tracking system. More direct sun light on Photovoltaic (PV) modules leads to enhanced energy yield. Therefore, tracking systems are implemented to improve the performance of PV system by tracking sun trajectory. The current design of Maximum Power Point Tracking (MPPT) trackers are more efficient than conventional single state solar power generation. Then by comparing two designs initially produced, Maximum Power Point Tracking (MPPT) tracking devices are found to be at better efficiency than static models. The system locates maximum- power generating point using an MPPT controller. The base line results of this study were obtained via physical implementation of simulated system to analyze the various parameters. The system then uses a quadratic-equation based algorithm that calculates the quadratic function corresponding to the maximum power generation point. With the advent of different applications of PV solar power, system planners have been implementing different strategies and techniques to maximize the output of solar system with commonly available technology in market. Additionally, various mathematical techniques were utilized to analyze the results gathered from the physical implementation. The simulation results also implemented to compare between the hardware and software of the project. The comparison of static Photovoltaic output graphs with real time measured values for the systems and a Dynamic Photovoltaic Maximum power point Solar Tracker (MPPT) system was observed. Both PV systems were implemented practically to get appropriate results and mainly all the equipment and services utilized in installation are widely available in local market.

This paper aims toinvestigatethe risk of physical fatigue at different levels of posture and repetition during manual handling task. Ten subjects with nohistoryof musculoskeletal disorders performed manual handling tasks at three levels of posture and two levels of repetition. The task completion time is recorded during the experimental task and the subjects rated their perceived discomfort level after the task completion. The results indicated that the lower posture of hand at higher repetition resulted in higher perceived discomfort level that leads to higher risk of physical fatigue. The higher repetition requires higher rest time for recovery and required lengthy completion time. The findings of this study served as a reference to the manufacturing industry in manual handling task design and planning to mitigate issues related to work-related physical fatigue at different levels of posture and repetition that could lead to the risk of work-related musculoskeletal disorders (WMSDs).

This paper explains the role of REPUSM in providing alternative education for Rohingya refugees’ children in Penang island. Rohingya refugees are Muslims from Myanmar (Burma). They are forced to flee across the border of their country of origin due to the persecution of the government and the abuse from the locals Buddhist. This desperate condition leave Rohingyas people no choice, except to be refugees. Unfortunately, lives as refugees are not easy especially in Malaysia because the host government have not recognized them. However, the government still allow the United Nation High Commissioner of Refugees (UNHCR) to assist the Rohingyas and other refugees based on humanitarian aspect. The Rohingyas are lives in uncertainty because the government is not responsible to assist them. Hence the reason why other parties in Malaysia took some initiatives to aid them from several aspects, including the Research and Education for Peace Unit, School of Social Sciences, Universiti Sains Malaysia (REPUSM). This department is from academic background that strives to assist the Rohingya in Penang Island. But, as an academic institution, helping Rohingya refugees is challenging because of certain difficulty. Therefore, in order to overcome the problems, the REPUSM took the alternative way to create a foundation body and register it as non-governmental organization to have a better operation for the sake of Rohingya refugees. As NGO, it helps REPUSM to manage and provide alternative education for Rohingya children with hope they can adapt the local culture and environment in Penang.

In this modern era, truck driver turnover still remains a challenging issue in the trucking business of Malaysia for a very long time now. Not only does it result in an increase in cost and service disturbances, it also has a severe impact on the sustainability of trucking firms in the market. In an effort to control high driver turnover, trucking firms have tried to execute different driver recruitment and retention procedures that include salary increases, rewards and easy-going schedules. With reference to this challenging scenario in Malaysia, this paper seeks to investigate the influencing factors that lead to truck driver shortage in the field of haulage. Besides that, this paper investigates on the factors that can encourage truck drivers in remaining with their job. In order for the paper to reach its objectives, survey questionnaires were distributed to truck drivers throughout the district of Johor Bahru to attain relevant data. The researcher expects that there are many more reasons as to why truck drivers decide to quite their job and more effective strategies should be studied and implemented in order to retain these worthy and qualified drivers from leaving the company. Retaining qualified as well as well-disciplined truck drivers is basically the ultimate goal of all haulage firms as this would save a lot of incurred expenses especially when recruiting new drivers.

Authors: Hanafi Muhammad
Published: October 2019

In this postmodern era, an era of technological sophistication is the culmination, Islamic education always has its own appeal to continue to be studied more deeply and comprehensively. It is interesting to know, that Islamic education in particular is the brainchild of Islamic scientists, both Western and Eastern. One of them is Ibn Thufail, an Andalusian (Spanish) thinker and philosopher of Islam. His full name is Abu Bakr Muhammad Ibn ‘Abd al-Malik Ibn Muhammad Ibn Muhammad Ibn Thufail al-Qaisyi al-Andalusi. The concept of Ibn Thufail's education is related to the problem of sources and methods of acquiring knowledge. Related to Ibn Thufail's source of knowledge divides into two, namely human sources (physics) and divine sources (metaphysics). Whereas the method of acquiring knowledge that was conceived was a method based on ratio, senses and intuition or soul.

Published: October 2019

Al-Qur'an study is a study that is needed in this millennial era, because various types of streams that appear endless are caused by a lack of understanding of the Qur'an itself. The emergence of these schools on the basis of the interpretation of the Qur'an textually without considering the current conditions. In addition, the interpretation of the Qur'an is carried out without sufficient scientific basis. This study of the Qur'an aims to provide understanding to all who need to interpret the Qur'an. With these discussions, it can help to prevent textual interpretations of the Qur'an from happening again, but it can open up insights in interpreting the Qur'an contextually. Because the times are so in need of a foundation in acting and behaving.
Poligami Perspektif Hermeneutika Fazlur Rahman

Published: October 2019

Polygamy is one area that is still warm to be discussed. Sensitivity is very flexible when faced with psychological and emotional factors of women. In this part, there was a polemic and many rejected it. And not a few women also agree to polygamy. There is also in the realm of economics, power and order of disharmony become part of the reasons for men to carry it out heavily. Because this part demands justice. It is at this point that the focus of study and academic anxiety is viewed from the aspect of hermeneutic science. The term hermeneutics is often used as a method of interpretation in the Qur'an because hermeneutics is the reading of texts from the historical side and the relativity of life. Even more hermeneutics is interpreted as an understanding of the contextual to look for the meaning behind the text of the verse. Related to the interpretation of the verse polygamy, among some classical commentators say that, the context of polygamy in the Qur'an is still permissible, because the interpretation uses the understanding of the text in the sense that it is in accordance with what is mentioned in the Qur'an without considering the implications will happen in life. However, there are contemporary scholars who offer to be tested and reviewed their sociological value so that social disintegration does not occur. This is an interesting issue in Fazlurrahman's thought to try to reinterpret themes related to polygamy using the hermeneutic approach. Thus, this paper highlights Fazlur Rahman's hermeneutic approach that has been applied in interpreting verses of polygamy in the Qur'an.

Deep Neural Oracles for Short-window Optimized Compressed Sensing of Biosignals
Authors: Mangia Mauro , Prono Luciano , Pareschi Fabio , Rovatti Riccardo , Setti Gianluca
Published: October 2019

The recovery of sparse signals given their linear mapping on lower-dimensional spaces can be partitioned into a support estimation phase and a coefficient estimation phase. We propose to estimate the support with an oracle based on a deep neural network trained jointly with the linear mapping at the encoder. The divination of the oracle is then used to estimate the coefficients by pseudo-inversion. This architecture allows the definition of an encoding-decoding scheme with state-of-the-art recovery capabilities when applied to biological signals such as ECG and EEG, thus allowing extremely low-complex encoders.

As an additional feature, oracle-based recovery is able to self-assess, by indicating with remarkable accuracy chunks of signals that may have been reconstructed with a non-satisfactory quality. This self-assessment capability is unique in the CS literature and paves the way for further improvements depending on the requirements of the specific application.

As an example, our scheme is able to satisfyingly compress by a factor of 2.67 an ECG or EEG signal with a complexity equivalent to only 24 signed sums per processed sample.

RESENHA - A CORROSÃO DO CARÁTER: CONSEQUÊNCIAS PESSOAIS DO TRABALHO NO NOVO CAPITALISMO
Authors: Pereira Gabrielle Tavares
Published: October 2019

A obra está dividida em 8 capítulos e um apêndice, escritos numa linguagem simples, porém densa, com uma profunda análise sociológica das transformações do mundo do trabalho.

A marca mais importante da obra de Sennett é a personificação dos conflitos existentes e advindas desta transformação. Ao longo dos capítulos, se define o tempo capitalista, como também se compara o velho e o novo capitalismo. O autor aplica às pessoas, às suas histórias e às concepções diante da vida e do trabalho, fontes como:  tabelas, dados econômicos, narrativas históricas e teorias sociais à luz de Max Weber, Adam Smith; entre muitos outros.

Senett escreve sobre o trabalho e suas transformações, suas relações na modernidade e as consequências nos valores como a lealdade e a reciprocidade, sob sua perspectiva de caráter: “traços pessoais a que damos valor em nós mesmos, e pelos quais buscamos que os outros nos valorizem”(P.38), e como definir nossas características pessoais, nosso valor, em uma sociedade onde tudo é flexível, passageiro, cujo o valor é medido por meio da capacidade de se ajustar a novas situações.

Não é possível construir um caráter em um ambiente onde não há metas a longo prazo, pois a construção deste depende de valores duráveis, relações duráveis (de longo prazo) isto não é possível em uma sociedade em que as instituições vivem se desfazendo ou sendo continuamente reprojetadas. Para além da problemática apresentada, fica claro que a expectativa não é uma simples decisão entre avançar rumo ao precipício ou retroceder ao paraíso e sim de uma leitura histórica de um tempo que culmina em um apontamento de possíveis saídas e reflexões dentro de um novo tempo.

O artigo aborda a atual contrarreforma do ensino médio instituída pela Lei n. 13.4015/2017, que aprovou a Medida Provisória 746/2016, bem como implicações da Emenda Constitucional 95 e das leis da terceirização e trabalhistas, a fim de compreender as particularidades da política atual, à luz do conceito de “estado de exceção”. A análise é ampliada para a “atualização” das Diretrizes Curriculares Nacionais do Ensino Médio (DCNEM) aprovadas em novembro de 2018, e a Base Nacional Comum Curricular (BNCC) desta etapa da educação básica aprovada em dezembro do mesmo ano, considerando a forma antidemocrática de implantação da política e demonstrando como essas regulamentações viabilizam aspectos contrários aos interesses da classe trabalhadora, numa lógica própria de obtenção do consenso e exercício da coerção no “estado de exceção”. Finalmente, apresentam-se reflexões sobre medidas recentes que podem comprometer o projeto de formação humana que busca ser hegemônico na Rede Federal de Educação Profissional Científica e Tecnológica.

Acceptable Noise-Level Stability Over a One-Year Period of Time
Authors: Bryan Melinda F. , Gordon-Hickey Susan , Hay Ashton L. , Davis Shelby T.
Published: October 2019

Background: The acceptable noise level (ANL) is a measure of willingness to listen to speech in thepresence of background noise and is thought to be related to success with amplification. To date, ANLshave only been assessed over short periods of time, including within a session and over a three-week andthree-month time period. ANL stability over longer periods of time has not been assessed.
Purpose: The purpose was to examine the stability of ANL over a one-year time period.
Research Design: A repeated-measures, longitudinal study was completed.
Study Sample: Thirty young adults with normal hearing served as participants. The participants weretested at two different sites.
Data Collection and Analysis: Two trials of most comfortable listening levels (MCLs), background noiselevels (BNLs), and ANLs were assessed for each participant during three experimental sessions: at0 months, six months, and one year.
Results: Two-way repeated-measures analysis of variances revealed no significant change in MCLs,BNLs, or ANLs within a session or over a one-year time period. These results indicate that ANLs remainstable for one year in listeners with normal hearing.
Conclusions: The finding that the ANL is stable over a longer period of time supports the theory that theANL is an inherent trait of the listener and mediated at in the central auditory nervous system.

Published: October 2019

A comprehensive ultrasonic investigation of molecular interactions in the polymeric solution of polypropylene glycol (PPG)-400 and ethanol at 303 K has been performed using the data available in literature. Several acoustic parameters such as acoustic impedance, isothermal compressibility,
molar sound velocity, molar adiabatic compressibility, internal pressure, free volume, van der Waals constants, molar cohesive energy and relaxation time have been explored. Thermo-dynamical parameters viz.: available volume, intermolecular free length, relative association, surface tension,
pseudo-Gruneisen parameter, Debye temperature, diff usion constant, coefficient of thermal conductivity and latent heat of melting have been evaluated. Several thermo- elastic parameters such as Young modulus, shear modulus, bulk modulus and Poisson's ratio are also determined. Excess parameters
are computed to study the relative molecular interactions and strength of interaction between the constituents of the polymer mixture. The volume expansivity data is used to evaluate Moelwyn-Hughes parameter, reduced volume, reduced isothermal bulk modulus, Sharma's constants, Huggins parameter,
isobaric, isochoric, and isothermal lattice Gruneisen parameters, fractional free volume, repulsive exponent, Bayer's non-linear parameter, cohesive energy density and characteristic temperature. Schaaff 's collision factor theory, Jacobson's free length theory, Nomoto's relation, Van Dael-Vangeel
relation, impedance dependence relation, Junjie relation and ideal mixing relation have been used to evaluate ultrasonic velocities in the system under study. The obtained results have been compared with earlier experimental results. The non-ideal behaviour of the mixture has been explained
in terms of its composition and variation of its acoustical and thermo-dynamical parameters.

Traditional power ultrasonic vibration systems can process one object at one time and only have one output. A directional converter of longitudinal vibration with multiple outputs composed of an input rod, a hemispherical vibrator, and three output rods is presented. The frequency equation
used in the design is derived with free edges at the input and output ends of the converter, as well as the continuity of displacements, forces, and angles of rotation at each component junction. The resonant frequencies of three fabricated converters designed using the proposed method are
in good agreement with those from the finite element method and also with tested values. With the input end of the converter joined with a piezoelectric transducer with a resonant frequency of 19.8 kHz, the longitudinal vibration modes and displacement amplitudes of the output ends of the
three converters at their resonant frequencies are tested. The results show that longitudinal vibration can be transferred from the input end to the multi-output ends through the converter. Furthermore, there exists a linear relationship between the excitation voltage and the displacements
of each output of the converter.

Presented are the results of laboratory experiments on investigating manifestations of acoustic emission (AE) of a gouge-filled fault during stick-slip. The laboratory experiments were held at the slider-model setup, when a granite block slides along a rough granite base under normal
and shear loads. In the course of experiments we altered the structure of the two-component filler of the fault and focused on variations of the AE parameters. The kinematic parameters of fault slip events in all the realizations remained approximately the same. The eff ect of gouge structure
on the statistics of AE has been revealed. An alteration of proportion of quartz sand / glass beads in the filler of the fault was accompanied by an alteration of the b-value of frequency-energy distribution from 0.53 to 0.85, and the p-value of Omori law from 1.00 to 2.06. Also,
it has been demonstrated that the nucleation of a slip event is accompanied by an alteration of the mechanism of AE generation – at the initial stage the 'tensile crack' signals prevailed, while at the final stage – the 'shear crack' signals did. The alteration of AE genesis manifested
vividly in a corresponding alteration of the emitted waveforms for all the realizations.

Acoustic geo-sensing deals with the derivation of spatial information from audio data. Motivated by the rising field of sensing information in (smart) cities, we present current perspectives and a methodological update on the acoustic-based solution of recognition problems in a complex
urban real-world scenario. In particular, we examine a static and a sequential approach for the automatic recognition of a cyclist's route between fixed endpoints, the route direction, and the route progress, solely based on the audio data recorded with a cell-phone attached to the cyclist.
To this end, we introduce the freely available 'Graz Cell-phone Cycle Corpus extended' (GC3+) that consists of more than 25 h of GPS-annotated audio material recorded in the southern urban area of the city of Graz, Austria. Promising recognition results confirm
basic feasibility of acoustic geo-sensing in an urban environment. The approach's theoretical potential of being generalised to support the solution of position tracking problems on a multi-dimensional urban grid gives reason for the implementation of acoustic geo-sensing methodology in a
number of real-world applications.
Construction of Ground Subtracks for Aircraft Noise Calculations Using an Estimate of Lateral Flight Dispersion
Authors: Schwab Olivier
Published: October 2019

In the absence of position data such as radar data, aircraft noise calculations usually rely on the definition of flight geometries in terms of flight track and flight profile data. Typically, the ground track is constructed as a backbone track with a number of subtracks accounting
for the lateral flight dispersion. Depending on the nature of the tracks, for instance when considering diverging tracks compared to very narrow tracks, the number of subtracks needs to be such that smooth noise contours and footprints are computed, putting a requirement on the minimum number
of subtracks needed. In practice however, as the tracks need to be digitized by expert hand, the number of available subtracks is often limited. Furthermore, the location of the subtracks is often unknown, requiring corridor boundaries to be estimated and to be translated into subtrack locations.

This paper presents a method for the construction of the required number of subtracks based on an estimate of lateral flight dispersion. Two cases are envisioned: the first being an estimate of the lateral flight dispersion using a set of three pre-existing subtracks (one backbone track and
left/right subtracks), the second being an estimate using a backbone track and corridor boundaries. The method uses geometric matching of the original tracks, followed by an estimation of the local lateral track dispersion. The lateral distribution function is then used for the construction
of new subtracks. A series of aircraft noise calculations using diff erent numbers of subtracks are shown, showcasing the influence of the number of subtracks on the noise contours, depending on the nature of the tracks (e.g.situations with tight turns).
New Investigations into Measurement Techniques Using the Pendulous Hammer to Assess Acoustic Insulation in Relation to User-Generated Noise in Residential Buildings

With the release of the revised version of the Swiss standard SIA 181:2006 "Protection Against Noise in Buildings", a measurement technique was introduced for simulating user-generated noise in bathtubs, shower cubicles, wash basins etc. employing a pendulous hammer. Despite the undoubted
advantages of the measurement method, over the past few years questions have increasingly been raised regarding various issues involved in its use. The characteristics of the pendulous hammer are insufficiently well specified in the standard and a procedure specifying a periodic check of the
instrument is lacking. The measurement method itself is described in inadequate detail, so that (for example) depending on the choice of the excitation, potentially very diff erent results may be obtained. In addition, no information is given regarding the measurement uncertainty. The standard
gives level corrections for diff erent excitation scenarios. This allows a comparison of the diff erence between the level of the original noise and that generated by the pendulous hammer. The validity of these level corrections is now, to a certain extent, being challenged. In addition, it
has been suggested that – depending on the constructional details - the airborne noise emitted by acoustic radiation from the component under investigation is excessive, thereby potentially falsifying the measured values. These issues have been investigated by Empa and, based on a comprehensive
set of laboratory and field measurements, clarified. Measurement protocols are given for various components, and the measurement uncertainty has been evaluated. The eff ect of airborne noise has been shown to be acceptable for tests conducted in accordance with the SIA 181 standard. Sufficient
measurement data is now available to allow the level corrections to be determined. Finally, specifications for the pendulous hammer itself have been formulated.
Airfoil Trailing Edge Noise Reduction Using a Boundary-Layer Bump
Authors: Shi Yuejun , Lee Seongkyu
Published: October 2019

This paper presents a new idea of reducing airfoil trailing edge noise using a small bump in the turbulent boundary layer. First, we develop and validate a new computational approach to predict airfoil trailing edge noise using steady RANS CFD, an empirical wall pressure spectrum model,
and Howe's diff raction theory. This numerical approach enables fast and accurate predictions of trailing edge noise, which is used to study the noise reduction from the bump for various airfoil geometries and flow conditions at high Reynolds numbers. Three types of bumps, the suction-side
bump, pressure-side bump, and both-side bumps, are studied. The results show that all types of bumps are able to reduce far-field noise up to 10 dB compared to clean airfoils, but their impacts are diff erent in terms of the eff ective frequency range. Also, bumps with four diff erent heights
are compared with each other to investigate the eff ect of the height of bumps on noise reduction. It is demonstrated that a bump causes velocity deficit within the boundary layer near the wall. This velocity deficit results in reduced turbulence kinetic energy near the wall, which is responsible
for trailing edge noise reduction. Overall, this paper demonstrates the potential of a boundary-layer bump in trailing edge noise reduction and sheds light on the physical mechanism of noise reduction with boundary-layer bumps.
Reconsideration on Helmholtz-Kirchhoff Integral Solutions for Boundary Points in Radiation Problems
Authors: Been Kyounghun , Moon Wonkyu
Published: October 2019

The Helmholtz-Kirchhoff integral (HKI) formula is very useful when designing transducers because it can be used to predict the acoustic pressure of a radiator at any position given only the acoustic pressure and velocity of the source. Many studies have been carried out to determine
how to predict the acoustic pressure distributions generated by radiator sources using the HKI formula and boundary conditions. However, if the surface integration process includes radiator edges or vertices, then it is difficult to predict a consistent acoustic pressure distribution accurately,
and the precise HKI formula to solve this problem and rigorous derivation are not known. In this article, to overcome these limitations, a formulation of the HKI for the boundary is proposed. This formulation is based on intuitive considerations and proven mathematically. Using the proposed
expression of the HKI formula for the boundary, the acoustic pressures radiated by irregular surfaces were calculated and compared with the distributions obtained by the finite element method and theoretically exact solutions. The results obtained with the proposed formulation of the HKI were
confirmed to be more accurate than those of the conventional HKI formula.
A Comparison of a One-Dimensional Finite Element Method and the Transfer Matrix Method for the Computation of Wind Music Instrument Impedance
Authors: Tournemenne Robin , Chabassier Juliette
Published: October 2019

This work presents a computation tool for the calculation of wind instrument input impedance in the context of linear planar wave propagation with visco-thermal losses. The originality of the approach lies in the usage of a specific and simple 1D finite element method (FEM). The popular
Transfer Matrix Method (TMM) is also recalled and a seamless formulation is proposed which unifies the cases cylinders vs. cones. Visco-thermal losses, which are natural dissipation in the system, are not exactly taken into account by this method when arbitrary shapes are considered. The introduction
of an equivalent radius leads to an approximation that we quantify using the FEM method. The equation actually solved by the TMM in this case is exhibited. The accuracy of the two methods (FEM and TMM) and the associated computation times are assessed and compared. Although the TMM is more
efficient in lossless cases and for lossy cylinders, the FEM is shown to be more efficient when targeting a specific precision in the realistic case of a lossy trumpet. Some additional features also exhibit the robustness and flexibility of the FEM over the TMM. All the results of this article
are computed using the open-source python toolbox OpenWind.
