  • Review on sentiment analysis in Tamil texts

    • Abstract: Sentiment Analysis (SA) is an application of Natural Language Processing (NLP) to analyse the sentiments expressed in the text. It classifies into categories of qualities and opinions such as good, bad, positive, negative, neutral, etc. It employs machine learning techniques and lexicons for the classification. Nowadays, people share their opinions or feelings about movies, products, services, etc. through social media and online review sites. Analysing their opinions is beneficial to the public, business organisations, film producers and others to make decisions and improvements. SA is mostly employed in English language but rare for Indian languages including Tamil. This review paper aims to critically analyse the recent literature in the field of SA with Tamil text. Objectives, Methodologies and success rates are taken in consideration for the review. We shall conclude from the review that SVM and RNN classifiers taking TF-IDF and Word2vec features of Tamil text give better performance than grammar rules based classifications and other classifiers with presence of words, TF and BoW as features.

  • A markov model for investigating the stock market volume behavior

    • Abstract: In recent decades, the stock market prediction has become a high research area due to its immense importance not only for every profitable industry, but also for shareholders and investors to hug out a self-assured decision for a good investment into the stock market. This paper provides a discrete time stochastic model for the behavior analysis of stock market volume, applying the Markov model. The proposed model is validated in terms of model assumptions to predict the stock market behavior. An illustration, the top ten largest global banks’ stock market behaviors through the steady-state distributions and expected number of transitions are discussed. Wherein the secondary datasets for 505 days of volumes from 1st of January 2014 to 31st of December 2015, 2 year duration are used in each bank. Published on 2018-12-31 00:00:00
       
  • Effect of microwave heating on the quality and shelf life of whole grain
           wheat flour under air-conditioned storage

    • Abstract: A study was conducted to evaluate the quality changes that could be occurred in the whole grain wheat flour during the storage and also to study the effect of microwave heating in the quality of the wheat flour. Whole grain wheat flour was packed in low density polyethylene bags separately as microwaved and non-microwaved and the quality changes were assessed for 12 weeks under air-conditioned storage temperature of 27°C. The quality characteristics such as smell, sieve test, long moisture, moisture NIR, protein NIR, ash NIR, wet-gluten, fat acidity, colour and weevil count were evaluated in 2 weeks interval. Fat and fiber content were evaluated in 4 weeks interval. Healthy cake was prepared from microwaved and non-microwaved flour and the sensory characteristics were evaluated using seven point hedonic scale method at the end of 4 weeks. The results of the study revealed that there were no significant differences (p>0.05) in the quality parameters of whole grain wheat flour in protein, ash, smell, fat and fiber whereas moisture, wet gluten, colour and the fat acidity changed significantly during the 12 weeks of storage. There was no any weevil infestation found in both flours. Sensory characteristics of the healthy cake were not affected by storage in both microwaved and non-microwaved flours. It was found from this study that, whole grain wheat flour can be stored under air-conditioned temperature of 27°C for 12 weeks from the date of manufacture. Published on 2018-12-31 00:00:00
       
  • Development and quality evaluation of ready-to-serve (RTS) functional
           beverage prepared from Bael (Aegle marmelos L.) fruit

    • Abstract: A research study was carried out to develop a RTS functional beverage by exploiting the medicinal, nutritional and organoleptic properties of bael fruit pulp. Six treatments of bael RTS beverage such as 2, 4, 6, 8, 10 and 12 % (w/w) of pulp concentration were prepared with sugar, citric acid, distilled water and 70ppm of potassium metabisulphite (KMS), considering the findings of preliminary studies and Sri Lankan Standards (SLS 729) for RTS fruit beverage. The prepared RTS were assessed to determine the physico-chemical properties, organoleptic characteristics and microbial safety. The results of the physico-chemical analysis revealed that ascorbic acid and total sugar contents increased from 3.63 to 11.9 mg/100 ml and 11.92 to 15.04 % respectively while the titratable acidity and total soluble solids remained constant; at 0.5 %, 10° Brix, respectively with the increase in the pulp concentration from 2 to 12 %. Results of the sensory evaluation showed that there were significant differences (p<0.05) between treatments in terms of colour, aroma, consistency, taste and overall acceptability. There were no microorganisms observed in the RTS beverages. From the results of quality assessments, the formulated bael fruit pulp RTS beverage with 6% of pulp concentration was found to be superior and could be suitable for consumption up to a minimum period of 12 weeks without any significant changes in the quality characteristics.

  • Novel interval multiple linear regression model to assess the risk of
           invasive alien plant species

    • Abstract: Invasive Alien Species (IAS) can be considered as a serious threat to the existence of the environment as they alter physical, chemical and biological components of the environment. Invasive potential of species can be recognized by their biological traits. Therefore, it is very important to model the risk of species using biological traits before going into a new environment. The purpose of this study is to build interval multiple linear regression models with interval input-output data to evaluate invasion risk of IAS related to biological traits.  A new method has been proposed to estimate the interval regression coefficients. Two different regression models are developed using interval least square algorithm. In the first model we use the method developed by Chenyi Huand the second model is newly developed. The estimated accuracy of the model that is developed by the proposed method is higher in comparison to the model with Chenyi Hu method. These two models are validated using known invasive and non-invasive species. The model that incorporates the proposed method provides better prediction of risk of IAS.

  • A mathematical and numerical analysis of a compartmental model for a
           single strain dengue epidemic in the presence of vaccination

    • Abstract: Dengue disease has presently emerged as an alarming public health concern of mounting significance with the unprecedented number of cases reported worldwide annually, especially from the tropics and subtropics. It is currently considered as the most critical vector borne viral disease in the world due to the acute health, social and economic issues that it causes in the endemic countries. Further, human mobility, climate change, rapid urbanization and public unawareness have led to a substantial dissemination of dengue in new geographical settings with explosive outbreaks. Also, the disease burden has aggravated due to the unavailability of specific clinical therapeutics and effective vaccines for the dengue disease. In such a context, this paper intends to investigate the dynamics of dengue disease in the presence of hypothetical vaccination strategies. Thus, we use a classical compartmental model with mathematical and numerical analyses in order to emphasize the importance of vaccination as an effective measure of disease control. We are hence of the belief that this paper will be a source of motivation for the medical scientists involved in the development of vaccine candidates for the dengue disease.

  • Storage evaluation of cookies produced from composite blends of wheat and
           sweet potato flour

    • Abstract:  A study was conducted to develop incorporated wheat and sweet potato flour cookies and to assess the quality of cookies during storage. Different composite blends of wheat flour and sweet potato (cv. Wariapola Red) flour were mixed in the ratios of 100:00, 80:20, 60:40, 40:60, 20:80 and 00:100, were then developed. These cookies were packed in sealed laminate aluminum foil. Cookies were stored under ambient conditions of average temperature of 30+1 °C and relative humidity 75-80 % for evaluation of the shelf life. Cookies were subjected to quality assessments at two week intervals for the entire storage period of 6 months. Among the treatment, the composite superior cookies supplemented with 40 % sweet potato flour contained 1.75 % ash, 4.15 % fiber, 5.42 % fat, 6.76 % protein and 84.4 % soluble carbohydrate at the end of 12 weeks of storage. However, moisture content of these cookies increased from 1.35 to 2.01 % which is within acceptable range for long term storage. The results of organoleptic assessment revealed that there were no significant differences (p < 0.05) between the treatments in terms of colour, mouth feel and overall acceptability while taste and texture had significant differences (p > 0.05) among the tested treatments. From the results of quality assessments, 40 % composite cookies could be stored in above mentioned conditions for a minimum period of 12 weeks without any significant changes in the quality attributes.

  • Linear programming approach for doctors scheduling in a hospital

    • Abstract: The main objective of this study is to propose an optimization model for achieving efficient scheduling of doctors attached to any hospital. In the recent literatures, a wide variety of different methodologies and models have been developed pertaining to various scheduling problems. These include Mathematical Programming, Meta-Heuristic Methods and Constraint Satisfaction Techniques. First, an optimization model is formed by formulating the objectives and the constraints of the problem mathematically. Further, the real doctors’ scheduling problem is formed as a 0-1 Integer Linear Programming problem. To solve the problem, Branch-and-Bound technique is applied by using the optimization software package LINGO. Finally, the solution to the optimization problem is converted to a regular doctors’ schedule. The methodology is illustrated by preparing a weekly schedule for a private hospital in Sri Lanka which has 32 doctors of the same grade. Published on 2017-12-01 00:00:00
       
  • Determining the optimum inventory level of a production line - a case
           study on an umbrella manufacturing company in Sri Lanka

    • Abstract: The top level management often addresses the capacity, inventory, demand, and customer satisfaction as separate decisions which lead to sub optimization of financial results and conflict of interests. Therefore this study considers the above variables simultaneously. The objective is to minimize the cost of production and lost demand. Cost of loss demand was included through the service level which is the probability of not being stock out. The SKUs are grouped into three based on their revenue contribution and allocated the service level. The production capacity varies mainly due to the number of working days and working hours, therefore will be a sub problem within the model. The optimization model was developed as a linear programming model as used Excel Solver to identify the optimum solution. The developed model generates the optimum cost compared to the current level by identifying an equilibrium between the cost of production and loss demand. Published on 2017-12-01 00:00:00
       
  • The Effects of Climate Change on Rainfall Pattern in Warri Metropolis,
           Nigeria

    • Abstract: The study examines rainfall characteristics in Warri metropolis for the past 30 years (1986-2015). Rainfall data was collected from the archives of Nigerian Meteorological Agency; and oral interview was also conducted. The study exploited rainfall characteristics such as daily, monthly and yearly amount of rainfall, intensity, frequency, variability, trends, return period and fluctuation of rainfall. Simple Linear Regression analysis and Standardized Rainfall Anomaly Index (SAI) were used to analyze the data. Among other findings, the correlation coefficient (-0.156) shows a negative relationship between rainfall and time (years). The trend line regression equation Y=243.75-0.4572X, confirms that rainfall in Warri Metropolis is decreasing at the rate of -0.45 per year. Recommendations given included continual monitoring and study of rainfall characteristics and other climatic data and dissemination of such information for planning purposes; drastic reduction of gas flaring in the metropolis, legislation against indiscriminate deforestation and need for proper urban planning.
