  • Space Debris Removal Mechanism Using CubeSat with Gun Shot Facilities

    • Abstract: Space derbies is a very perilous problem and most of the proposed methods for space debris removal are not successfully serviceable for all sized space junk. Keeping in view the limitation of the existing methods of debris removal techniques an active approach is needed and in this regard required to be instigated purposefully. In more than half a century of space activities, by using above 4800 launches have placed around 6000 satellites into orbit, of which less than a thousand are still operating. In this research, a new concept to remove small space junks of Low Earth Orbit (LEO) is proposed which functions by using CubeSat with Gunshot equipment. The target of this concept is to confiscate the small-sized space junk of ranges 0.2 to 1 inches diameter and which will be identified by collaborating with FGAN radar. CubeSat is loaded five bullets of 0.1 kg with strong thruster gunshot technology and after the first shot, reaction force will help to change the orbit of the satellite to find out the second space debris. This research intended to comprehend and helps to get assess of small-sized space debris removal activity in terms of the simple business model.
  • Elderly People Fall Detection System Using Skeleton Tracking and

    • Abstract: The fall detection systems use a variety of technologies like sensors, wearable devices, color camera, thermal camera etc. With the use of Microsoft Kinect camera for non-gaming purposes, depth images have started being utilized for fall detection. Various authors have made an attempt at using Kinect for fall detection in combination with a variety of techniques like ellipse analysis, bounding box analysis etc. However, most of these attempts fail to differentiate between human subjects and other inanimate objects and fail to identify the person who has fallen while assuming that there is only one person who needs to be monitored. This paper proposes a new system that is based on the depth images captured by Microsoft Kinect, skeleton tracking and bounding box analysis. The key novelty of this system is that it wraps the moving object into the bounding box and determines the change of size of the moving object by analysis the motion over the time to distinguish the human moving object and non-human moving object. The system stores the joint measurements of the known people in a database and compares the joint measurements of the detected person with the values in the database to identify the person. The proposed solution provides a significantly higher accuracy rate as compared to the current best solution and especially when the person carrying an object, sweeping the floor, dropping an object and picking an object from the floor.
  • A Novel Weighted Integral Energy Functional (WIEF) Algorithm: Augmented
           Reality (AR) for Visualising the Blood Vessels in Breast Implant Surgeries

    • Abstract: The use of Augmented Reality (AR) for visualising blood vessels in surgery is still at the experimental stage and has not been implemented due to limitations in terms of accuracy and processing time. The AR also hasn't applied in breast surgeries yet. As there is a need for a plastic surgeon to see the blood vessels before he cuts the breast and before putting the implant, this paper aims to improve the accuracy of augmented videos in visualising blood vessels during Breast Implant Surgery. The proposed system consists of a Weighted Integral Energy Functional (WIFE) algorithm to increase the accuracy of the augmented view in visualising the occluded blood vessels that covered by fat in the operating room. The results on breast area shows that the proposed algorithm improves video accuracy in terms of registration error to 0.32 mm and processing time to 23 sec compared to the state-of-the-art method. The proposed system focuses on increasing the accuracy in augmented view in visualising blood vessels during Breast Implant Surgery as it reduces the registration error. Thus, this study concentrates on looking at the feasibility of the use of Augmented Reality technology in Breast Augmentation surgeries.
  • Effect of Y2O3 Additions on Microstructure and Properties of
           Alumina–Magnesia Ceramics

    • Abstract: The purposes of this research are to prepare and investigate the characterization of 0.7MgO-xY2O3-(99.3-x)Al2O3 by varies x at 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0 wt% (AMY). AMY samples were synthesized by solid state reaction under two different sintering methods conventional sintering method (NS) and two stage sintering method (TS). Ceramic samples were sintered by conventional sintering at 1600°C for 5 h and using two stage sintering with the first sintering temperature (T1) at 1600°C for 30 min and cooling down to the second sintering temperature (T2) at 1450°C for 10 h. The phase composition of the samples were characterized using XRD technique. XRD patterns from two method sintering revealed phase combination of Al2O3, MgAl2O4, MgO and Y2O3. It was found that it is not different XRD patterns from two method sintering. SEM micrographs form NM and TS showed that the shape of the ceramic grains were polyhedron and ellipsoid, while the grain sizes form NS were in the range of 0.91-1.00 μm and the grain sizes from TS were in the range of 0.34-0.48 μm. The samples from NS and TS is showed optimum mechanical properties by AMY with Y2O3 additions between 4-6 wt%.
  • Solution of Second Order Ordinary Differential Equation Associated with
           Toeplitz and Stiffness Matrices

    • Abstract: In this work we develop a technique solution of second order ordinary differential equation (integrating by parts) to reach to Toeplitz matrices and Stiffness matrix to solve O.D.Es. We investigate that solution numerically using finite difference method and we  find the error between exact and numerical solution computed using  finite element.
  • Real Time Object Tracking and Protection: Hybrid Logistics Architecture in
           Ubiquitous Environments (HLAiUE)

    • Abstract: Realtime object security and vehicle tracking have not been successfully implemented in commercial vehicles due to limitations in processing large amount of data and hardware capabilities. This paper aimed to improve the object security, processing power and data storage in a distributed environment. The proposed system (HLAiUE) consists of a three-layer architecture, first layer is used to collect data, second layer distributes the data processing and the last layer stores the processed data. The designed architecture improves the performance and security by applying data compression algorithms in a real time and removes the hardware dependency by processing the data in a distributed environment using Hadoop and Spark framework. The results demonstrate that the proposed architecture improves processing time by 80% compared to other algorithms and provides more reliability, security and flexibility due to ubiquity and the absence of hardware dependency in comparison with other existing architectures which are hardware dependent. Also, using an NOSQL database server in a distributed environment optimizes data storage by up to 80% and is flexible because all the infrastructure is in a distributed environment. The proposed architecture improves the object tracking by implementing compression technique in a distributed architecture. Thus, this system improves the accuracy up to 80% without depending on hardware resources.
  • Characterisations of Parameters of Granularity of Sediments from Togolese
           Littoral: Granular Potential

    • Abstract: The present study aims at analysing the dimensional distribution of granulate grains all along the Togolese littoral and identifying the law of their longitudinal distributions. In this regard two hundred and ten (210) samples are collected all along the Togolese littoral from the Togo-Ghana border up to Togo-Benin border and another ten (10) samples on each side of a spike located at 37.5 PK. Samples dried at 105°C for 20 h are then subjected to screening test. Their longitudinal size distributions, uniformity coefficients and bendings are then specified. It is apparent that the sediments of the Togolese littoral consist of grains of category ‘’F3’’ that are getting bigger and bigger, less and less tight, badly graduated and more open in accretion and erosion zones in the direction of the littoral drift. Natural and artificial works all along the Togolese littoral enable to identify three categories of sediment (fine, medium-size and big) corresponding to properly determined usages in the concrete.
  • Knowledge, Motivations and Barriers Regarding Blood Donation Among
           Students in Different Undergraduate Majors

    • Abstract: The present work aims to investigate barriers, motivations and perceptions as well as the role of students’ future profession with respect to their propensity to donate blood, in students enrolled in different university undergraduate majors: Nursing, Psychology and Economics. Considerable research has underscored that it is crucial to create publicity campaigns differentiated on the basis of target groups’ needs and characteristics. University students have been used in many studies to investigate motivations and barriers regarding blood donation, but their specific undergraduate majors have infrequently been studied. A self-report questionnaire was administered to 1,842 students in five different universities (Mean age = 23.27, SD = 5.04, females = 78.3%). The results show differences between the different typologies of the students investigated. Students in the Nursing major demonstrate more knowledge about donation and higher motivations to donate and perceive fewer barriers. They also acknowledge the greater relevance and responsibility existing between their academic major and blood donation. Economics students feel more distant from the world of donation while Psychology students occupy an intermediate position. These differences in knowledge and propensities underscore the necessity of evaluating formative/informative programs in relation to the target group in order to achieve maximum efficacy in interventions and to numerically increase donors of blood and blood products.
  • Effects of Extended-Rotifers Inclusion and Live Food-Enrichment with
           Probiotics on the Survival, Metamorphosis, Development Time and Growth of
           Mud Crab, Scylla paramamosain (Estampador) Larvae

    • Abstract: The present larval nutrition study was conducted to evaluate the effects of feeding probiotic-enriched rotifers inclusion mixed with Artemia until zoeal stages 4 (Z4) and Z5 on the survival, metamorphosis, development time and growth of mud crabs, Scylla paramamosain larvae. The efficiency of the feeding regime was tested by two-factor analysis. A 4&times;2 factorial experimental design with eight combinations of enriched or un-enriched or a mixture of enriched and un-enriched live food (factor 1) in each of two feeding regimes (factor 2) in triplicate was setup. After 24 days of larval cultivation, there were no significant (p>0.05) interactive effects between the two selected factors on survival and metamorphosis rate of larvae. Larval survival in all treatments, under both factors, decreased gradually (p<0.05) during the cultivation period. From 15 Days After Hatching (DAH), the survival and metamorphosis rates of larvae fed both enriched rotifers and Artemia were higher (p<0.05) than those of the larvae without enriched live food. Similarly, from 18 DAH onwards, the extension of rotifers inclusion mixed with Artemia until Z5, irrespective of enrichment, showed higher (p<0.05) survival, metamorphosis and growth of megalopa than when the rotifers were included only until Z4 stage. Overall, an amalgamation of extending rotifer feeding and enriching them at the same time with Artemia can result in considerable improvements in survival and metamorphosis which can in turn, have beneficial impact on the technical feasibility of a commercial crab hatchery.
  • An Improved Object Detection Technique for Hazard Avoidance Systems

    • Abstract: Hazard detection and avoidance at construction sites working with heavy equipment and moving vehicles is one of the biggest issues in modern surveillance. Background subtraction using a Gaussian Mixture Model (GMM) is widely utilized for identification of moving objects with most existing methods leading to improvements but lacking accuracy of object detection. This paper aims to improve accuracy and processing time for object detection. The proposed algorithm consists of a correlation coefficient to reduce the existing geometric error and provide more accurate detection of moving objects by comparing foreground and background pixels in every frame. A Kalman filter is used for keeping track of the object. The results demonstrate that the proposed algorithm outperforms existing applications in terms of accuracy of object detection. On this basis, it is recommended that object detection with a correlation coefficient of background and foreground pixels of objects can be used for hazard detection in real-time monitoring systems such as traffic monitoring and detection and tracking of humans.
  • Short-Term Effects of Aroma Therapeutic Herbal Steam on Heart Rate
           Variability and Stress

    • Abstract: This experimental research aims to examine the short-term effects of aroma therapeutic herbal steam on heart rate variability and stress. In this experimental study, the participants were 60 diabetic patients with stress who had rated their stress in the Suang-prung Stress Test-20 at the level of 3 or higher. They were divided into the treatment group (n = 30) and the control group (n = 30) using a simple random sampling method. The former was administered aroma therapeutic hot steam, whereas the latter received standard conventional medical care. Both before and after the experimental period, both groups were assessed in terms of their Heart Rate Variability (HRV). The within-group HRV values, namely SDNN, RMS-SD, LF and HF, for both the treatment and the control groups pre- and post-treatment differed significantly (p<0.05). Additionally, when the between-group values post-treatment were considered, the SDNN, RMS-SD and LF values for the treatment group were significantly higher than those for the control group (p<0.05). Based on the findings, it can be concluded that aroma therapeutic hot steam will interact with factors triggering stress and enhance parasympathetic nervous system function, thereby reducing stress levels. This is proof that the treatment should improve the conditions of diabetic patients suffering from stress.
  • Characterization of the Earth's Surface State by Unsupervised
           Classification: Case of Vegetated, Aquatic and Mineral Surfaces

    • Abstract: In this study, we propose an unsupervised classification scheme based on the Dempster-Shafer Theory (TDS) and the Dezert-Smarandache Theory (DSmT) to characterize vegetated, aquatic and mineral surfaces. From pre-processed ASTER satellite images (georeferencing, geometric correction and 15 m re-sampling), neo-channels were produced by determining the spectral indices NDVI, MNDWI and NDBaI, considered as sources of information for classification of a given pixel. NDVI is a contrast function to highlight vegetation. By account, the MNDWI makes it possible to characterize the water and the NDBaI makes it possible to recognize the mineral resources. Then, we modeled respectively the formalisms of the DST and the DSmT, these formalisms are modeling tools close to advanced probabilities based on the notions of belief and fusion functions to take into account certain imperfections (uncertainty, ignorance, etc.) encountered in the acquisition of images. In addition, the DST manages a formalism of disjunction between the sources during the DSmT simultaneously manages a disjunction and a conjunction between the sources. Next we realized the algorithms and related codes that we implemented in the MATLAB environment. Our contribution lies in taking into account the imperfections (inaccuracies and uncertainties) linked to source information through the use of mass functions based on a simple Gaussian distribution support model in order to model each focal element independently of the others and to evaluate the belonging of a pixel to a class with respect to the majority of elements representing said class. The resulting results show that the DST approach is relatively satisfactory for the unsupervised classification of mineral surfaces and aquatic surfaces while it is not satisfactory for vegetated surfaces according to all proposed models. As for the DSmT, it presents satisfactory results for all the models proposed. The model with the exclusion integrity constraint E∩V ∩ M = φ was selected as the best model because having, in addition to an average rate of well-graded pixels of 93.34%, a compliance rate (96, 37%) with the terrain higher than those of the other models implemented.
  • Sentiment Analysis: Comparative Study between GSVM and KNN

    • Abstract: Sentiment classification aims detecting general opinion of users in social media towards business products or daily life events. The classification tells whether sentiment is positive or negative. Techniques of sentiment classification are categorized into lexical analysis and machine learning techniques. In this paper, we propose a comparative study between SVM applied genetics (GSVM) against KNN algorithm in terms of speed and accuracy. We present also an experimental study of sentiment classification on different domains movie reviews, financial and amazon toys products. The experimental results shows that GSVM achieves a classification accuracy of 92% and KNN achieves 87% on movie reviews dataset. For classification speed, KNN shows a remarkable improvement (above 10% improvement) in comparison with GSVM.
  • Determination of Dynamic Viscosity of Viscous Oils using Mach Zehnder
           Digital Holographic Method

    • Abstract: The digital in-line holography based on Mach Zehnder interferometer (MZDIH) was setup for the determination of dynamic viscosity of the viscous oils. The spherical irons were used as the falling objects in the viscous oils. The hologram images of the iron falling along its entire path were recoded as a video file on the CMOS camera. The recorded hologram images were reconstructed on the holoviewer program via MATLAB. Then, the diameter and velocity of the iron were obtained. Finally, the dynamic viscosity of viscous oils were determined and compared with standard values. From the experimental results, it can be concluded that the MZDIH method is the simple and precise tool for determining the dynamic viscosity of fluids.
  • Juvenile Delinquency: Evidence of Challenges in Rehabilitation

    • Abstract: Juvenile delinquency is a global phenomenon that affect children’s developmental process and represent a significant concern for the society. Despite the fact that it is a global issue, its effects are felt more in developing countries such as Ghana due to inadequate resources available to rehabilitate them. However, the study explored the procedure used in admitting inmates into the juvenile detention facilities and challenges in rehabilitating them and recommended strategies based on findings to improve on the rehabilitation system. Using a quantitative research methodology, simple random and purposive samplings were used in selecting 94 respondents for the study at the senior correctional centre. Data obtained from the inmates was analyzed with SPSS and descriptive statistics with frequency distributions were employed to explain the data. The findings indicated challenges that affect both care takers and inmate at the centre regarding human resources, inadequate training period, facility to house inmate and the proper procedure for admission into the correctional facility. These challenges showed that, there are gaps in the rehabilitation process which mission is to make delinquent children valuable members of the society after they are released. Rather many juvenile delinquents stand high risk of becoming criminals in their adulthood.

    • Abstract: According to the Nigerian National Population Commission 2006, the population of the nation was conservatively estimated to be over one hundred and seventy million. The challenge of nutritional quality to feed an increasing national population places a higher demand on poorly grown conventional plants. Thus the need to incorporate wild edible plants to bridge the extended gap between the conventional vegetable and the wild indigenous edible plants informs this research. The daily intake of vitamins and minerals are obtained from vegetables. Wild edible plants serve as food and medicine. In this study, the delicacies were prepared from two novel wild edible vegetables - Ceiba Pentandra (CPD) and Ficus glumosa (FGD). They were evaluated for nutritional quality. Their minerals and vitamins content were determined using standard methods. These delicacies were fortified with a diet of experimental rats. Twenty four (24) albino rats weighing 43.99 - 81.49 g were randomly arranged into six groups (n = 6) of six rats per group. Two groups were fed with the formulated experimental diets, while the other two were fed with protein-free (casein) and basal diets. Vitamins C and E, carbohydrate and protein were significant in CPD delicacy at (28.47±3.17%). The mineral composition showed low Na+ level, while Ca2+ concentration was also low in CPD and FGD. Phosphorus and Mg+2 were high in FGD. The FGD-fed rats had a low biological value (%) (1.38±0.01%) compared to CPD (2.29±0.01) and reference (casein) group (3.02±0.01). The reference group consumed the highest amount of food -97.06±14.70 g, followed by the basal group (88.98±10.61, with CPD having (76.46±18.78) and FGD (48.27±18.27), respectively. There were no differences in the body weight, protein efficiency ratio, net protein utilization, net protein retention, true digestibility, fecal and carcass protein levels in all the test groups. Findings indicate that nutrients from these wild vegetable delicacies may have good quality and could meet the nutritional needs of the consumer if utilize as per the standard.
  • Comparison of 10 cm and 50 cm Long Iodine Cells in Iodine-Stabilized Diode
           Laser-Pumped Nd:YAG Laser at 532 nm

    • Abstract: An iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm was developed at the National Institute of Metrology of Thailand (NIMT) for the first time in Thailand. Two iodine cells with the lengths of 10 and 50 cm were used for the comparison of frequency stability of Nd:YAG laser. The experiment was set for phase modulation spectroscopy. The Nd:YAG laser was locked to the a10 component of the R(56)32-0 transition of iodine molecule. The variation of wavelength with time and the frequency stability were carried out at various iodine cell temperatures of 20, 10, 5, 1, -1, -3 and -5°C. The results from the frequency stability measurements showed that the lowest Allan standard deviation value of 6.643×10-10 was obtained at -5°C for 50 cm long iodine cell. From this Allan standard deviation value, it can be concluded that the iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm developed in this study is acceptable to be used with a gauge block interferometer for the length calibration of the gauge block.
  • Microwave-Sensitive Reactors to the Rescue: From Microwave-Assisted
           Chemistry to Environmental Applications

    • Abstract: The idea of using microwave sensitive reactors is relatively new in chemistry and environmental areas. Applications in both areas might be different but the effects can be amazing. Flow through reactors coated with thin metallic films using a variety of deposition techniques have been used as vessels to conduct reactions in flow under microwave irradiation. The metal coating not only did not provide any impediment to the process, it served a two-fold purpose. Metallic coatings acted as catalysts for the flow through processes; in addition the flowed reactions were tremendously accelerated due to unusually high temperatures generated within reactors because of coupling of microwaves to metal films. The methodology of developing microwave active reactors has been successfully extended to environmental applications, transcending chemistry, such as distillation of saline/brackish waters for the purpose of generating potable water. The experimental distillation device described here as a proof of concept, will lay a foundation for a high throughput water sanitizing process, delivering potable water to large groups of people.
  • A Real-Time Optimization Approach to the Efficiency of a Photovoltaic
           System by a Hybrid Tracking Technique using LabVIEW

    • Abstract: Among the lines of research on improving the efficiency of a photovoltaic panel, sun tracking techniques occupy a large part. In this article, an extension of Laboratory Virtual Instrument Engineering Workbench (LabVIEW); LabVIEW Interface For Arduino (LIFA) is used. It allows the driving of an Arduino board from LabVIEW, on which a collaboration technique between two categories of pursuit is developed: The first is sensory and the second is pre-programmed. This hybrid two-axis technique is characterized by impulse control strategist with pre-programmed control and dual sensory correction. The results reveal that the hybrid tracking system gave an additional energy gain of about 36% compared to a fixed photovoltaic panel system. Thus, it has practically a percentage increase of 2 and 2.3% respectively to the two techniques used.

  • Minimizing Transmission Time under Required System Capacity Constraint in
           Stochastic-Flow Networks

    • Abstract: In the case of an existing limited capacity of the system called required system capacity, in this study a new method is presented to determine the disjoint paths to send data from the source to the sink. System reliability is evaluated as the probability that a specified amount of data can be transmitted from a source to a sink through two disjoint paths, subject to a time threshold and a required capacity. In addition, we study the effect of using the proposed method on the reliability evaluation in comparison with other previous methods.
  • Management of Effective Factors in Components’ Supply Chain on
           Losses of Electric Distribution System

    • Abstract: Restructuring in the electrical distribution utilities, the loss management is one of the critical activities to enhance network efficiency. Accordingly, management of technical loss would be the main target of the asset managers. For loss management, the usual methods of loss calculation and estimation need numerous data which is not used to real networks. In this research, a practical method for loss management is introduced from the viewpoint of components’ supply chain to the network. For this purpose, sub-indictors are extracted using focus group for each process of this chain and their probability distribution functions are calculated. Then, permissible values of sub-indicators are determined by the Delphi method and to calculate new probability functions, the deviation of each process is calculated. Finally, a real network with historical data is used here to study the proposed method. The results illustrate that the most deviation is in the sub-indicator design process about 91% in the viewpoint losses.

           Internet Banking Information Systems

    • Abstract: Nowadays, banking transactions are one of the most important daily services that fulfill a society needs. The broadly growth of information technology usage pushed banking institutions to embrace advanced technology to launch new electronic services. Internet technology has influenced the banking practicability because of its capability to enhance performance of financial operations. A major concern of Internet banking systems is the customers’ perception of service quality that render Internet banking a unique environment due to the lack of physical interaction between bank personnel and the customer. Thus, there is a necessity need for banking institutions identify factors that convince customers and raise their intention towards usage of these services. The purpose of this paper is to set forth a valid means and contribute to the field of measuring online service quality with a focus on optimizing this perception via electronic transactions in the domain technology of the banking industry and its reliability by examining the most important factors affecting customer perception towards acceptance of Internet banking in Jordan. The conceptual framework formulated and developed in this research study is an extension to the Technology Acceptance Model (TAM). The model was tested with a survey sample of 500 banking customers chosen randomly. The findings of the study indicate that all mentioned factors in the hypothesized model (TR, SP, QI, AW, PU and PEU) have significant impact within creating a positive atmosphere for stimulating the acceptance and use of Internet banking systems. Data analysis is based on the Statistical Package for Social Science (SPSS).
  • Effects of Enriching Nitrogen and Phosphorus on the Growth of Sargassum
           Podacanthum Cultured in Potassium-Fortified Inland Saline Water

    • Abstract: Potassium-fortified inland saline water (K+ISW) has shown potential for growing marine species, including seaweed species. The response of a brown seaweed species, Sargassum podacanthum, to nitrogen and phosphorus enrichments were evaluated by culturing the species for 84 days in K+ISW and comparing it with Ocean Water (OW). The culture media were enriched weekly with ammonium chloride and sodium dihydrogen phosphate, with ammonium and phosphate ratios of 10:1 at five different concentrations 80:8, 120:12, 160:16, 200:20 and 240:24 μM. The culture medium with no enrichment was used as a control. The water quality and biomass of S. podacanthum were measured fortnightly. The S. podacanthum biomass increase significantly with different concentrations of the nutrient supplementations. The standing biomass and Specific Growth Rate (SGR) of S. podacanthum were similar in OW and K+ISW in the absence of any nutrient supplementation and at the supplement concentration of ammonium and phosphate 160:16 μM. However, from day 42 onwards, at the ratios of 80:8, 120:12, 200:20 and 240:24, S. podacanthum cultured in OW grew significantly faster than in K+ISW. In K+ISW, optimal growth of S. podacanthum was observed at the 160:16 and the increase in biomass was significantly higher than the initial biomass until day 70, whereas at the other four nutrient supplement concentrations, the S. podacanthum biomass remained unchanged during the entire culture period. The nitrite, total Kjeldahl nitrogen and phosphate concentrations in water were found to be significantly (p
  • Effects of Temperature and pH on the Growth of Sargassum linearifolium and
           S. podacanthum in Potassium-Fortified Inland Saline Water

    • Abstract: This study tested the effects of temperature and pH on water quality and the growth of Sargassum linearifolium and S. podacanthum in potassium-fortified Inland Saline Water (ISW) of Western Australia (WA), at two levels of pH (low pH range of 5.5-6.5 and ambient pH 7.0-8.2) and two levels of temperature (high temperature 26-27°C and ambient room temperature of 20-22°C) in triplicate for 42 days. The pH of ISW in WA varies from 3.9 to 9.1, whereas the temperature is from 6.1-28.1°C. The results showed that the high temperature initiated the mortalities of the both Sargassum species from the first 14 days of culture period. The high temperature also resulted in a reduction of dried weight and ash content of these two species of Sargassum by the end of the trial. S. linearifolium temperature tolerant threshold was larger than S. podacanthum. Since the day 14, the S. linearifolium biomass and specific growth rate were higher than S. podacanthum at both temperature levels under ambient pH. Higher crude protein in S. linearifolium than S. podacanthum was also recorded at high temperature. Ambient pH and ambient temperature resulted in higher biomass and higher specific growth rate than low pH and high temperature in both species, which is recommended for Sargassum spp. growth.
