This study tests the effects of the financial performance of local governments on the level of welfare in 25 city/regency in South Sulawesi during 2009-2014. The financial performance is measured by the rate of local autonomy, the effectiveness of local own-source revenue, budget harmony, and budget absorption, while the welfare society measured by the Human Development Index (HDI), unemployment and poverty level. The regression analysis showed that the performance of region autonomy proved to increase the HDI over the next year and to reduce the poverty rate in two and three years ahead, however, does not correlate with the unemployment. The effectiveness of local own-source revenue can lower unemployment at two and three years ahead but failed to increase the HDI and to reduce poverty. Harmony of spending also neglected to raise the HDI and to reduce the level of unemployment, although it can alleviate poverty. The level of budget absorption can improve HDI, and reduce the unemployment at two and three years ahead, but failed to lower poverty. No previous study has comprehensively studied the Effects of Level of regionality autonomy, and effectivity of local own-source revenue to public Welfare, and the moderation effect of Expenditure harmony, budget absorption in relationship between financial performance of local government to public welfare, especially in Indonesia.

The main study in this work is to derive the mathematical model of the cantilever based pressure sensor. Two steps of mathematical modelling are being applied, mechanical and electrostatic, for finding the factors affecting the output of the sensor. Two main modes of operation for piezoelectric pressure sensor are transverse and longitudinal which are described in details. For 3D structure analysis, COMSOL 5.2 multiphysics simulator is used for simulation to validate the mathematical analyses output. A comparative analysis is done for simulated output of mechanical stress and the mathematical calculated stresses of the sensor. Similarly, the simulated output voltage and mathematical calculated voltage are also analyzed. The factors affecting the sensitivity of the sensor are the length, the thickness of the mechanical structure of the sensor, thickness of the sensing material and the piezoelectric voltage coefficient (g31). The output voltage of the sensor is linearly vary with the input pressure with negative slope. The sensitivity of the sensor for simulated is -0.012 mV/Pa and mathematical is -0.017 mV/Pa.

Routing protocols play a crucial role in determining the rate of data transfer on IoT networks. In the absence of routing protocols it will be difficult for the IoT networks to deliver ubiquitous services to its end users. This paper uses AODV protocol for establishing communication among the source and sink node through simulations. AODV is energy efficient as compared to other reactive protocols as it selects the shortest possible routing path.Average values of transmission delay and energy consumption by the nodes have been calculated for network scenario of 30,40, 50, 60 and 70 nodes. The variation in energy consumption during communication process for all these networks have been studied which indicate that energy consumption varies with the distance among the communicating nodes in the routing path. Similarly delay also varies with the distance of the sink node from the base station.

This study aims to provide electricity or renewable energy for the people of Maluku who have not yet obtained access to state electricity services (PLN) or to people who enjoy electricity with a 100% elective electricity. The competitive advantage of power plants in this study is called "DISTRICT (Electric Dispenser) RSS-01". This is to reduce operational costs, because pure energy uses renewable energy in the form of pelton turbines driven by steam pressure from pressurized vessels / boilers. Boiler fuel is obtained from burning biomass such as: dry wood, durian skin, coconut shells, nutmeg shells, or walnut shells that are available in large quantities, but which are still not optimally utilized by the community. Water is fed into a pressure vessel / boiler and boiled until it turns into gas. Operational pressure in the boiler is maintained in variations of 1 and 2 bars. Pressurized water vapor is then channeled to press each blades of the pelton so that it rotates the wheels (runner) of the pelton turbine. The turbine then turns the generator dynamo to produce an electric voltage (Voltage). This research is to see variations in boiler vapor pressure on the amount of electric voltage generated. Research has produced boiler press up to 3 bars without damage (burst, leak). At a boiler pressure of 1 Bar, the charging voltage reaches 17.5 Volts, at a pressure of 2 Bar, the electric voltage reaches 20 Volts, while at a pressure of 2.5 Bar the accumulator charging voltage reaches 50 Volts. The resulting voltage has exceeded the maximum charging voltage limit, 15 volts. For this reason, regulators need to be installed to limit the input voltage to the accumulator.

The fast growth of wireless computer networks and multimedia applications means it is essential that these applications can be transmitted over the standard IEEE 802.11 Medium Access Control (MAC) protocol with high performance. Therefore, the aim of this paper is to develop a new schemed named Ratio Based that provides effective and efficient Quality of Service (QoS) provisioning in IEEE 802.11 DCF in a fair, scalable, and robust manner. Simulated wireless networks based on Network simulator (NS) package were carried out to examine and evaluate the impact of the proposed Ratio Based scheme on the network performance. The findings revealed that the IEEE 802.11 DCF protocol performed inadequately when transmitting various applications due to the limitations inherent in its operation. The study showed that inappropriate values of CWmin resulted in significant network performance degradations and demonstrated that it was important to select an appropriate set of MAC protocol transmission parameters in order to provide better performance. Ratio based scheme was developed to dynamically adjust the CW values according to the current and past network conditions. Using this scheme significant improvements were achieved in the performance of IEEE 802.11 DCF protocol.

Grouted splice sleeves are used in precast concrete construction and heavily reinforced concrete sections to splice two adjacent reinforcing steel bars. The behavior of such splices is a function in two important mechanisms: the bond behavior and the confinement action. In this paper, the mechanical behavior of simple, economic, and non- proprietary grouted splice sleeve connector under axial tensile load is investigated. Feasibility study for tested grouted sleeves reporting their adequacy in accordance with the code provisions of ACI 318-14 and ECP 203-2007 is presented. Moreover, design equations capturing the parameters affecting the bond strength, the confining pressure, and the required embedment length are derived. Four series with a total number of 57 grouted splices were fabricated to splice reinforcing steel bars of 12 mm and 16 mm in diameter and nominal yield strength of 400 MPa. The results showed that the confinement action added by the steel sleeve to the grouted splices significantly enhanced the bar-to- grout bond strength. The grout-to-sleeve bond was adequately secured by introducing a steel ring at both ends of a smooth sleeve. Importantly, 35 tested specimens are considered satisfactory in accordance with ACI 318-14 and ECP 203-2007 provisions for mechanical splices and can be used in field connection.

As Magnetic Resonance Imaging (MRI) is gaining popularity in the field of medical science, there are many ongoing researches to increase it’s accuracy and efficiency. In this work, the focus has been given to an already established parallel MRI reconstruction method named Iterative Self-Consistent Parallel Imaging Reconstruction: SPIRiT. SPIRiT uses coil-by-coil parallel reconstruction method and then applies sum-of-square (SOS) to produce the final MR image. The SOS recombination technique proved to be amplifying noise as well as it based on the assumption that parallel coil sensitivities are uniform. In this paper a convex optimization scheme has been implemented which not only can overcome the shortcomings of SOS recombination technique but also can provide a true optimal solution for SPIRiT. The SOS recombination of original SPIRiT has been replaced by a convex optimization formula and hen the upgraded SPIRiT method has been compared with original SPIRiT for proposed method’s legitimacy. It has also been shown that this research also has impacts on the scanning time. The comparison results cover the aspects of qualitative, quantitative and noise-based analysis to illustrate the efficiency of the proposed formula.

one of the most serious attacks nowadays is the Distributed Denial of service (DDoS) attack. DDoS attacks can be of two types: the layer-three (network layer) attacks and layer-seven (application layer) attacks, which can potentially lead to cyber-attack resulting in financial and reputational losses. Hence, network analytics play an important role in protecting the security of organizations. Traditional data analysis models have difficulties in defeating these attacks since they consume too much time analyzing different logs from different devices at the same time. Big Data analytics plays a major role in analyzing and correlating large volumes of disparate and complex data from different sources in different formats. Hence, we propose a model that combines Big Data and machine learning to proactively detect DDOS attacks through analysis, detection, and classification of network traffic. By using this model, organizations could gain higher service security and availability. The experimental results show that different attack scenarios are well classified, and DDoS attacks could be detected in the early stages

In this article, we present our approach for rapid, easy and safe web-based applications development. We implemented a new 2 Steps “Run then Specify” Model Driven framework, in which the development phase is postponed to be after (not before) the deployment phase.In this approach, the application development is based on a “descriptive and human readable” language. The language is composed of a set of predefined formal and readable business-components, which allows to manage the 3 tiers (client, business logic and storage) in one human readable and short sentence. The framework engine directly runs these business components; with no need for any further compilation or deployment. Moreover, this readable language enables the reconstruction of the business model when the analysis documents are lost or becme obsolete. This approach was implemented and tested within our framework built using J2EE, Jboss and several databases including MySql database, Oracle, Postgres and Sql server. To evaluate this approach, we compared its performance to Spring Framework. The average Time-to-Learn of our Framework was 20% of that of Spring, the average Time-to-Program of our framework was 25% of that of Spring and the average Number-of Code Lines that the developers wrote using our framework was about 11% of that they wrote using Spring Framework.

Remote sensing image segmentation is a very important stage in remote sensing image processing. In many different segmentation techniques such as KMeans, C-Means, Watersed ..., KMeans is one of the widely used algorithms for remote sensing image segmentation. However, this algorithm only considers the intensity of the pixel to lose the contextual information of the object, affecting clustering quality. The 2D-KMeans algorithm overcomes this disadvantage, but it increases the number of dimensions of each object. This results in the executing time of the algorithm is very large, especially when the large-scale remote sensing images is clustered. This paper presents the new clustering algorithm MapReduce_2D-KMeans in order to overcome the disadvantage of 2D-KMeans calculating time without reducing cluster quality.

One of the most important issues of sowing small-seeded crops (in the example of onions) is considered. The method of sowing has a great influence on crop yields. The choice of planting method is due to the need for a more uniform distribution of plants over the field area in order to optimize the conditions for their development. Studying the movement of seeds during the sowing process is the most important task. Because, the object of sowing is the seeds. The article provides an analysis of previous work on the precision sowing of small seed crops. And also, the flight and the trajectory of the seeds from the ejection window to the bottom of the groove were studied theoretically. In the research, methods of higher mathematics, classical mechanics, and impact theory were used in which it was possible to obtain the necessary equation. Based on the numerical solution of the obtained equation, graphs are constructed that determine the trajectory of falling onion seeds when ejected from the sowing apparatus and the graphical dependence of the recovery coefficient on the height of the sowing apparatus. And also installed, the installation height of the metering unit

The vibration method is the beginning of the use of vibropressing in the concrete compaction process. It is very different from the CPB compaction process. The most significant difference is in the practical volume. In concrete, 2m3 is compacted at the same place and time, while CPB at 15 liters volume is compacted at the same location at the same time, whereas more than 15 liters is compacted at the same place and at different times. With a compressive strength of about 25 MPa, it was using a composition of material with per m3 of 100 kg of cement, 380 kg of sand and 560 kg of stone ash, and using a water-cement ratio of 0,6. This research only changes three-parameter limited. They are vibration time between 7 and 8 seconds with the frequency at 30-50 Hz, engine pressure at 25 and 90 kg/cm2. The reason 7 and 8 second for the vibration time in this research is the maximum vibration time in CPB production. All specimens are made with the same mixture composition. There are 3 main parameters in the vibropressing process namely vibration frequency, engine pressure and vibration time, explained that the vibration frequency has the most influence in the process of increasing the compressive strength of CPB. By limiting the electric motor energy of 7 Hp, vibration time (7-8) seconds on engine pressure (25-90) Kg/cm2, this machine produces CPB optimum compressive strength (22-31) MPa at frequency (43-47) Hz.

One of the major challenges of the dual-hop energy harvesting (EH) a link is, to optimize the link parameters to achieve maximum signal to noise ratio (SNR) at the receiving end. In this paper, the optimum condition of three parameters: ‘power supply at source terminal’, ‘power splitting ratio’, and ‘gain of relay’ is achieved in four ways. In the first and second techniques, the above three parameters are optimized analytically from the profile of normalized channel capacity and bit error rate (BER), where the corresponding graphs show maxima and minima at the same optimum point. In the third technique, we find the separation between profiles of ‘normalized channel capacity’ of EH and non-EH minimum at optimum condition. In the fourth technique, we transmit grayscale images under 16-QAM using a proposed algorithm of pixel to modulated symbol conversion. We then measure the quality of the image in terms of SNR and peak signal to noise ratio (PSNR) in dB and we verify the optimum condition of the network by the quality of received images.

Quality improvement of Machine Translation (MT) is one of the open topics of research today. These days, there are many machine translators available online. But, these machine translators lack in the quality of translation when the input sentence is complex and consists of many Named Entities which are not identified correctly. In this paper, we address this problem by means of investigating a new ensemble approach that can help in improving the quality of translation from English to Hindi and Hindi to English. We have developed 6 MT systems that can perform English to Hindi Translation and 6 MT Systems that can perform Hindi to English Translation. We have developed Ensemble MT Systems by combining Statistical Machine Translation (SMT) with Source Text Rewriting and Named Entity Translation. We have compared translation using baseline approach (SMT) with the ensemble approach and have shown that quality of translation improves when we use ensemble approach for English-Hindi and Hindi-English Translation.

AC-WC and HRS Base pavement mixture are the type of pavement used as surface and base respectively. Durability of pavement will reduce after service due to the environmental effects. Hence, additives such as Styrofoam is added to enhance the stability and durability. This research investigates the durability of the pavement at the surface and base course. Marshall specimen containing 1.5% Styrofoam was prepared and immersed for 0, 1, 3, 7 and 14 days in order to determine the Residual Strength Index, First durability Index and Second Durability Index. These indexes represent the durability of the pavement. From this study, it was found out that the Residual Strength Index value decreased with the increment of immersion duration for both layers. The IDP and IDK with Styrofoam of AC-WC were higher than the specimens without Styrofoam which were 0.377% and 7.752% respectively. Similar trends were observed for HRS Base. This implies that the use of Styrofoam in the pavement is advantageous because it has the potential to improve the durability of mixture.

In this paper, we compare the normalized channel capacity of single user and multiuser models of primary user (PU) aided cognitive radio network (CRN). The single user model gives the best performance; however, it often fails to represent the real life environment. On the other hand, multi-user model represents more realistic scenarios of wireless links; however, its performance is worse than that of single user. Therefore, we propose a new communication model for selecting the appropriate PUs as relay nodes that is based on the geometry of service area, the offered traffic of PUs and the existence probability of PUs in an appropriate position. Through simulation experiment, we prove that the proposed model gives more realistic results compared to the previous works on multi-user model in CRN.

This study aims to implement noise reduction algorithm with a selected mean filter (SMF) and to investigate its computation time in the denoising process on X-ray fluoroscopy images. The SMF was the mean filter (MF) technique, but in its application, selected pixels within threshold value were only used to calculate the average pixel value. The effectiveness of SMF was then compared to well-known filters, such as adaptive mean filter (AMF) and bilateral filter (BF). The notebook of Acer Nitro 5 Intel Core i5-8300H 2.3 GHz with 8GB RAM, Graphic Processor Unit (GPU) Nvidia Geforce GTX 1050 4GB, and the Windows 10 Home operating system with SSD M.2 NVMe 2280 256GB were utilized. The algorithm was implemented using Matlab R2019b. The fluoroscopy images of NEMA SCA & I Cardiovascular Fluoroscopic Benchmark Phantom with size of 512 x 512 pixels were filtered, exposure factors of 69.92 kV and 583 mA and a dose-area product (DAP) of 1,660 mGy-cm2 with a field of view (FOV) of 25 cm. In addition, image quality of the filtered images was assessed, including noise level, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and spatial resolution. The results showed that by using the SMF, the higher improvement of image quality in terms of noise level, SNR, CNR, and spatial resolution compared to AMF and BF, was achieved. The time needed by SMF to process an image was about 0.36 seconds, while the AMF and BF are 10.6 and 1.4 seconds, respectively. The SMF was as fast as a traditional MF, which only need 0.33 seconds for an image.

The study evaluated the effect of eco-friendly cost on net revenue of quoted cement producing firms. Eco-friendly cost is incurred as an obligatory cost by organizations towards the welfare of the societies and the environments in which they carry out their operations. However, the purpose of this study was to ascertain how this cost affects the net revenue of the firms that incurred it. The study applied ex-post facto research design and data were collected from the secondary sources. The data were analyzed using the ordinary least square regression method. The findings revealed that sustainability cost and abatement costs do not significantly affect the net revenue of the studied firms. Nevertheless, the eco-friendly cost is as vital as all other costs of the firms further down the consideration and should be properly managed and ignore by managers of the respective organizations. Thus, it was suggested that the stakeholders have a duty to set a standard on environmental cost book-keeping to ensure that this cost is adequately disclosed whenever it is incurred and it should also be ensured that there is amenability besides limpidity in the procedure.

Tourism becomes as the major industry to develop the world’s economic wellbeing through regional development. Among the most attracted destinations cultural destinations were highly loyal destinations to the tourists as which have thousand years aged history and world recognized heritages (Udurawana 2018). More than the 84% of tourists have mentioned that their purpose of visit Sri Lanka is ‘pleasure’, and Sri Lanka has more tourists’ attraction year by year, as Sri Lanka Tourism Promotion Beouro (SLTPB) promotes Sri Lanka highlighting its 2000 aged history and eight world heritage sites. However, statistics have proved that tourists attractions and growth rate was gradually decreased from 43% since 2010 up to now (SLTDA 2018), and cultural places are the least attracted places in Sri Lanka. Therefore this explanatory research study was conducted to identify the effect of experiential marketing strategies to tourists’ destination’s loyalty through the mediating effect of tourists’ satisfaction. Through the sound literature, experiential marketing was developed under second order model as the independent variable, and dependent variable was the destination loyalty. Population of the study has been identified based on the number of tourists visited cultural areas in the year 2018, and 600 tourists selected as a representative sample, through convenient sampling technique, and 513 tourists were final respondents. Well-developed research questionnaire was facilitated to collect tourists’ preferences being aligning to four research hypotheses (H1, H2, H3, and H4). On the results, all the constructs were valid, reliable, fit with the model. All the research questions and objectives were achieved, and all the hypotheses were accepted, where H1 – there is a significant effect of experiential marketing on destination loyalty, H2 - experiential marketing effect is on tourists satisfaction was positive and significant, H3 – Tourists satisfaction has positive and significant effect on destination loyalty, and H4 – accepted as there is a mediating effect with tourists satisfaction between the experiential marketing and destination loyalty. Finally researcher suggested adoptable strategies for the attention of SLTDA, DMOs, and other stakeholders at cultural areas in Sri Lanka, to upgrade tourists’ satisfaction through the experiential marketing practices for tourists’ destination loyalty

Free-space optical (FSO) technology has acquired a growing interest in optical wireless communication system. Although the FSO system presents outstanding advantages, it is highly prone to atmospheric turbulence. To mitigate this effect and enhance the performance of FSO link, a fusion of radio-frequency (RF) with FSO technique is quite prominent in these recent years. A comprehensive analysis is performed here with a view to inspecting the effects of atmospheric turbulence in terms of the BER characteristics of FSO link with RF sub-carrier modulation under strong turbulent channel with Gamma-Gamma (G-G) fading. Here, we consider single sub-carrier for avoiding the complexity of inter carrier interference (ICI) effect. Analysis is performed to find the signal to noise ratio (SNR), bit error rate (BER) and power penalty at the end of the coherent optical binary phase-shift keying (BPSK) receiver with RF sub-carrier optical intensity modulator. Simulation results indicate that the system performance deteriorates due to an increase in FSO link distance, and when the link distance is limited to 2-2.5 km, it requires a lower power penalty to achieve a satisfactory BER.

The enterprises face challenges to process and get insight from big data. It is very costly to compute and manage massive amounts of data. So, Serverless is such a technology that helps to analyze big data with low cost and high performance. Serverless cloud providers manage the operating system, servers, hardware and execute codes. Developers focus only on writing code rather than managing infrastructure. Serverless development has drawn a lot of attention in the market because customers only charged for executing code. Still, all users are not getting benefit from the Serverless technology due to appropriate solution architecture. Mostly an expert architect can ensure scalability, security, cost efficiency, etc. So users often pay for the right architecture to compute and store data in the Serverless cloud platforms. An architecture has been proposed with reduce charge and improve the performance of big data processing using Serverless technology and it is made using Amazon Web Services (AWS). The proposed architecture is evaluated using a real-world use case. As a case study, Movielens data are used in our model for personalized recommendation using Amazon personalized Hierarchical Recurrent Neural Networks (HRNN) algorithm.

The demand for higher data rate services has led to the emergence of 5G wireless networks to offer the limitations of the current cellular communication technologies. The millimeter-wave (mm-wave) communication technologies have evolved into direct Device-to-Device (D2D) single-hop or multi-hop communications. Direct D2D communication can easily be integrated into vehicular communication networks such as vehicle-to-everything (V2X) to offer high-speed data connectivity, very low latency, and reliable services. However, the implementation of D2D enabled vehicular communication networks are characterized by an architecture that causes misalignment of the mm-wave beams from the vehicles thereby causing mutual interference. The mm-wave communication is also having a challenge of high propagation losses, sensitivity to blockage, and directivity. In this regard, the coexistence of cellular users, D2D users together with the vehicular users’ calls for strict QoS requirements since there is the high mobility of the vehicles and the presence of mutual interference. This paper formulates a matching theory-based Hungarian algorithm to perform channel and power allocation that takes into consideration the high rate of channel fluctuations, interference, and latency constraints in the high mobility environment. The proposed Hungarian algorithm was simulated in MATLAB by applying 3GPP TR 37.885 and 38.901 specifications. The Hungarian algorithm is compared with the max-min algorithm. The Hungarian algorithm was found to have a 10.8% better performance than the max-min algorithm when the maximum spectrum efficiency was considered. When the minimum spectrum efficiency was considered the Hungarian algorithm was 17.35% better than the max-min algorithm.

It is necessary to ensure reliable protection of underground structures from moisture of barrier structures and underground parts of buildings. Hydroisolization of underground parts of buildings is one of the most laborious and responsible processes. Hydroisolation in the construction of buildings and structures is an average value of construction and installation work from 0,1 to 0,5%, but at the same time, 3 percent of the total labor costs that go to the restoration of the building. Repair of gidroisolytics is a complex, expensive and no less effective process. Therefore, it is necessary to ensure that the building is suitable for long-term durability, taking into account all the negative effects on the gidroisolization of underground parts of the building. In the following years, the results of research aimed at studying the technical condition of buildings and structures, as well as the archive data collected during the period of their exploitation, show that the technical condition of most of the previously constructed buildings deteriorated, there were violations in their Sokol parts.

The integration between spectroscopic devices and satellite imagery helps to enhance and increase the accuracy in post-processing steps of remote sensing imagery. This paper tries to test the capability of the device using an inexpensive spectrometer as ground measurements to improve the accuracy of imaging classification. Thereby, a low-cost spectrometer device has proposed in this research to test and evaluate the performance by comparing the spectral signature with USGS spectral library. The main goal of this research is to calibrate and test (accuracy and performance) of handheld spectrometer AS7265X multi-spectral sensor device for urban area application in order to enhance the remote sensing imagery classification and evaluate the accuracy of the AS7265X spectrometer device by comparing it with spectral library. Hence, the results show good discrimination proficiency for AS7265X handheld spectrometer for leaf vegetation in the field. The above results verified the reliability of the AS7265X through field measurement with USGU spectral library extracted for ENVI software in order to compare the spectral signature and obtain the accuracy.

Although self-compacting concrete (SCC) has excellent applicability for elements with complicated shapes and congested reinforcement, its supply cost could be two to three times of that of conventional concrete depending on the composition of the mixture and the quality control of concrete producers, which in turn might limit the applications to general construction. In this paper, the authors proposed the cost effective solution for SCC technology involving the industrial sand usage with application of combination-type for proportioning SCC. The advantages of industrial sand usage are two-fold; firstly this sand can be manufactured with the customized fine content, which can play a role to increase the powder content, and secondly the replacement of natural sand could relieve the scarcity of this material. SCC using industrial sand of strength class 30MPa was successfully designed in this study. Not only were the rheological properties in agreement with guideline and recommendation for SCC, but also the mechanical properties including compressive strength, flexural strength, splitting tensile strength and elastic modulus comply with the one prescribed in Eurocode for this type of concrete strength class. Besides, the cost analysis pointed out that this type of SCC has a 20% lower price on the basis of volume 1m3 in comparison with the conventional SCC.

Over the last century and a half, human have learned how to make synthetic polymers into plastic products. As awareness of environmental issues spread, the persistence of plastic waste began to trouble observers. Researchers and innovators are looking for a way to place more environmentally friendly biodegradable materials on the market than conventional plastics. Subsequently, biodegradable biocomposites have entered the market for use in agriculture, medicine, packaging, civil engineering and other sectors. Recently, natural or lignocellulosic fiber-based biocomposites have received a great deal of popularity for various industrial uses and applications owing to their low density and renewability and the major advantages of natural fibres. The physically and mechanically acceptable characteristics of these fibre-reinforced biocomposites (e.g. tensile properties, flexural stress-strain behavior, fracture strength, impact strength), make them more sustainable and attractive than other composites with a remarkable environmental degradability characteristic. This paper depicted a comprehensive review on conventional, advanced and automated fabrication techniques along with related scientific data in an organized way. The aim of this review is to include a thorough overview on biocomposites, natural fiber-reinforced biocomposites, lignocellulosic fiber-based biocomposites, various fiber-reinforced biocomposite production processes, major physical and mechanical properties of fiber-reinforced biocomposites, biocomposite materials and their potential growth.
