Advanced Persistent Threat (APT) is an exceptionally perilous attack with a specific target and purpose. It consists of various complex and devious techniques in order to be able to obtain a highly secured trade secret, sensitive information. Currently, the APT attack is tremendously difficult to deal with because of its unique design for each target, which makes prior experiences and rules less accurate in detecting APT attacks. In addition, the APT detection method also must not rely on any single procedures or solutions but to include several phases and technologies. On the other hand, correlation analysis technique is a mathematic one which figures how separate elements affect each other and produces conclusion based on multiple factors mutual properties. Hence, in this report, correlation analysis technique is proposed by the authors.

As the new era of computing technology begins with the start of the 21st century, the data produced by each person are increasing enormously day-by-day. Companies started to track one’s personal details from applications like media sharing, social networks, eCommerce, etc. since they have started to generate a lot of data traffic. The Database, where these heavy loads of generated data have been stored, had to scale out to handle the network traffic. Cloud computing arrival carves a solution for this trafficking problem by making data sharding a suitable option for scaling the data. This paper discusses about the importance of database sharding and the distribution of the database over the different server and also how sharding is helpful to scale the incoming amount of enormous data to control the data trafficking issues in the cloud database. Also compares the difference in the performance of database with and without sharding techniques using SQL server instance.

Increasing level of pollution day by day in atmosphere has developed a worried situation for all. The existence of human life is at risk. The emission of pollutants in the atmosphere especially green house gases have to be minimized immediately in order to prevent any type of natural disaster. Industries and automobile sectors are more responsible in emission of pollutants. The same has to be curbed and brought under control. Using biodiesel has proved to be environment friendly to a great extent. In this paper, the algae oil is used with Zirconium Dioxide (ZrO2) coated piston in order to improve the performance of the VCR engine in which the analysis for combustion and emission characteristics is performed. The considerable improvement in performance is observed with coated piston as more amount of heat developed is utilized for producing useful work.

Motion detection is the main agenda of this paper, with smart technologies. This paper shows how motion can be detected with efficiency and at the same time with durability of the system. Many IOT (Internet of Things) systems are designed for the same purpose but cannot assure a long run of the system. This paper makes use of chip set called NodeMCU that is well known for its durability and also efficient enough by consuming low power and cost effective. We generally find other boards like Raspberry Pi which aren’t very durable in nature. The same system can be developed using these chips in a cost effective manner, the only problem with these chips is their durability.

In recent days, On-Chip Communication is a major requirement in modern systems that produce efficient communication with less complexity and high throughput. Due to heavy traffic and increasing Network-On Chip (NoC) size, the routing algorithm produces poor performances. Normally, round-robin and matrix arbiters are used in NoC for high-speed switches. In this research work, three different types of arbiter algorithms are used such as priority algorithm, Time Division Multiplexed (TDM) algorithm, and Viterbi algorithm to improve the linearity of the NOC. Initially, the priority algorithm helps to minimize traffic congestion when the arbiter is in a busy mode. Second, the fairness and Quality of Service (QoS) of the NoC structure are analyzed by the TDM algorithm. Finally, the Viterbi algorithm based error prediction process is done in an NoC structure. Due to the usage of three proposed arbiter algorithms, the area of NoC can be reduced. The packet can be reached to the destination by using the arbitration process with less loss. In this research, the proposed methodology is called as Low Area- Fault-Tolerant Adaptive Arbitration based NoC architecture (LA- FTAA- NoC architecture). Finally, the Field Programmable Gate Array (FPGA) performance is evaluated such as LUT, flip flop, slices, and frequency in Spartan 6 hardware. In the proposed method, 2.42% of LUT, 3.1% of flip flop, and 8.63% of slices have reduced when compared to existing work.

We suggest a shading essentially based division theory using the Convolution Neural Network technique to observe tumor protests in cerebrum pictures of reverberation (MR). During this shading, the mainly based algorithmic division guideline with FCNN suggests that changing over a given dark level man picture into a shading territorial picture at that point separates the situation of tumor objects from partner man picture elective objects by fully exploiting Convolution Neural Network and bar outline package. Analysis shows that the methodology will succeed in dividing human mind images to help pathologists explicitly recognize the size and district of size.

Bagasse is one of the main by-products remaining from Sugarcane industry in tropical and subtropical regions. This by-product is used as a fuel in production of the sugar and a high amount of ash is remained due to this process. The remaining bagasse ash traditionally is used as a fertiliser, however recently it’s been used as a cost-effective additive in improvement of the mechanical characteristics of the soils by practitioners. This study investigates effect of addition of different percentages of bagasse ash on improvement of the compaction characteristics of the cemented kaolinite. The results showed that addition of bagasse ash increased the optimum moisture content of the soil (OMC) and reduced the maximum dry density (MDD). The recorded increase in OMC was attributed to the extra moisture that required to add for the hydration. Also, reduction in MDD was attributed to the weightless bagasse ash in compare with kaolinite clay.

Replacement of inorganic fertilizer with organic manure is welcome by the world due to health concern and increasing cost of production. In the coconut sector, inorganic fertilizers are heavily used and it is costly. Therefore, three treatment combinations were tried to supplement or replace the inorganic fertilizer with the organic manure for the coconut palms. The study revealed that completely forgetting the inorganic fertilizer with the tested amount of organic manure is not possible. Addition of organic manure to the existing inorganic fertilizer dose recommendation is not increasing the nut’s yield in number but the nut’s quality.

Published: March 2020

Assam, the fascinating land of blue hills and red rivers, is inhabited by a number of communities belonging to various ethnic origins with diverse cultures. These communities can broadly be divided into two categories viz. tribals and nontribals and they are found spread on the hills as well as the two valleys of the state. The non-tribal category of inhabitants can again be sub-divided into high caste Hindus, O.B.C.’s, M.O.B.C.’s and Scheduled Castes (SC). Numerically, Hiras occupy the fifth position among the Scheduled Caste of Assam. They are traditionally an occupational Caste who make pottery by means of hand. Economic backwardness of the Hiras can be attributed to their low income occupation. The people should be made realize that education is the only way to equip oneself for Socio-economic development.
Scarti, tracce e frammenti: controarchivio e memoria dell’umano

Scarti, tracce e frammenti: controarchivio e memoria dell’umano. Literature and art, increasingly interested in the dark side of production, now appear as a reservoir of fragments and waste of all sorts. The attraction towards scraps, conceived as anti-goods, testifies the existence of a parallel world where the myths of growth and productivity show their tragic face. Through different textualities and media, waste emerges as a testimony of a subversive marginality from which unexpected perspectives, which can undermine the established order, arise. The volume, using the image of waste, offers a hidden or marginalized counter history, which however 'returns' overbearingly in order to give contemporaneity its shapeless substance.
Trend of Regular Voluntary Blood Donation and its Associated Factors in Karachi - A Comparative Analysis of Medical and Non-medical Undergraduate Students
Authors: Jaffar Nazish
Published: March 2020

Background: Regular voluntary unpaid blood donation assures safe blood supply in association with minimum infection transmission. The purpose of this study was to identify the frequency of regular voluntary blood donation and to evaluate the causes of donating blood as well as factors impeding blood donations among the medical and nonmedical students of Karachi.

Methods: A comparative cross sectional study was conducted among medical and nonmedical students of JSMU and NED University respectively from May to October 2018. Sample size was 272 including 137 medical and 135 non-medical students. Data was analyzed using SPSS version 22.0. Chi-square test of independence/ Fischer’s exact test were applied to assess statistical significance.

Result: In medical group 5/21(23.8%) voluntary regular donors were recorded. In non-medical group, voluntary regular donors were found to be 8/30 (26.6%) (p>0.00). Medical students most commonly 15/21 (71.4%) donated blood voluntarily in a camp while non-medical participants frequently donated blood as replacement donors 13/30 (43.3%) (p>0.00). Major hindering factor for blood donation in both study groups was non-participation in blood donation derives i.e. 66/116 (56.8%) in medical and 53/105 (50.4%) in non-medical groups respectively. Anemia, 20/116 (17.2%) in medical and 15/105 (14.2%) in nonmedical students was the second major cause of not donating blood.
Conclusion: The frequency of regular voluntary blood donations is very low among undergraduates. However, comparatively, the trend is slightly higher among non-medical group. The major hindrance in not donating blood was non-participation in blood donating derives.
Assessing Knowledge of Zika Virus and a need for Continuous Medical Education (CME) in Post-Graduate Doctors of a Tertiary Care Hospital: A Single Center Experience
Authors: Sohail Abdul Ahad
Published: March 2020

Background: The 2015-2016 Zika Virus Outbreak caused global concern. A study was done to assess knowledge about viral hemorrhagic fevers amongst healthcare professionals, which found only 57% doctors knew clinical features of hemorrhagic viral fever. The aim of this research was to assess the knowledge of physicians as well as the need for continuous medical education.

Methods: A cross-sectional study was conducted on doctors working or undergoing postgraduate training in a private tertiary care hospital. A sample size of n=91 was reached after including most of the doctors working in these hospitals in the department of medicine, pediatrics, gynecology and obstetrics. Data was collected through self-administered questionnaire. Convenience sampling technique was employed. Informed oral consent was taken before administration of questionnaire. Analysis was done on SPSS version 20.

Results: The doctors included in the study were from the departments of internal medicine, which were 46.2% (42), pediatrics, which were 19.8% (18), and gynecology and obstetrics. Only 17.6% (n=16) participants knew that the Zika virus can affect pregnant women in any trimester. If pregnant woman is infected only 65.9% (n=60) of all doctors were aware of the fact that it can cause microcephaly in the infants. Thus, 44% (n=40) of the participants demonstrated correct knowledge that Zika virus is associated with the Guillain-Barré syndrome (GBS).

Conclusion: Our study determined that although many doctors demonstrated good knowledge regarding the clinical features of Zika virus, they had poor knowledge regarding the prevention of spread of disease.

Balancing Competing Needs among Stakeholders: Lessons from the Self-access Language Learning Centre (SALL) of the Chinese University of Hong Kong (Shenzhen)
Authors: Ng Kwan-yee Sarah , Gu Yang
Published: March 2020

The Chinese University of Hong Kong (Shenzhen), referred to as ‘University’ or ‘CUHK(SZ)’ hereafter, is a newly established private university located in the Longgong District of Shenzhen, which is a special economic zone in the southern part of China. Its first batch of about 300 undergraduate freshmen, all majoring in Business Administration, commenced studies in September 2014. The Self-access Language Learning Centre (‘SALL’ or ‘the Centre’ hereafter), as a unit under the School of Humanities and Social Sciences (SHSS[1]), was put into trial operation from 6th March to 4th June 2015 to explore students’ needs and preferences in self-access English language learning. The purpose of this progress summary is to delineate and analyze the trial operation. It is divided into two major sections. The first section is a brief description of the 3-month trial operation and evaluation whereas the second section details recommendations for the future development of the SALL and other self-access centres also needing to address conflicting needs among stakeholders.
Learning Space-Based Initiatives for Developing Learner Autonomy: Design And Implementation
Authors: Thornton Katherine
Published: March 2020

Recently, traditionally resource-heavy self-access centres have increasingly been reinvented as social learning spaces (Allhouse, 2014; Murray & Fujishima, 2013), usually with a greater emphasis on peer interaction and communication in the target language.

By elevating the communication aspect of a language learning space, however, there is a danger that the important task of developing metacognitive skills gets sidelined in favour of simply developing language proficiency through peer or teacher-student interaction. Language learning spaces that set themselves up as conversation lounges are missing a big opportunity to do so much more than just develop language proficiency in users. Learner autonomy should be a central mission of any language learning space. Indeed, a language learning space can be an ideal milieu for supporting learners to become autonomous. Unlike in the classroom, users of self-access and other non-classroom learning spaces already have a sense of being in control of their learning choices, even if they are not entirely sure how to exercise that control. It is therefore vital that support is offered to guide and support learners, and this support can take many formats. The best forms of support do not simply attempt to help learners make single learning decisions such as which materials to choose or service to use, but to support their long-term development as autonomous language learners.
Exaptating Students’ Social Networks as Affinity Spaces for Teaching and Learning
Authors: Murphey Tim , Fukada Yoshifumi , Falout Joseph
Published: March 2020

Students’ social networks can become exapted (Johnson, 2010) for the purpose of increasing language learning, or any other kind of learning, as well as the promotion of well-being, through what Murphey (2014) calls the well becoming through teaching (WBTT) hypothesis. The WBTT paradigm holds that people not only learn better when teaching others, but approach and maintain their well-being in wider social networks outside the classroom. The present study explored the impact of WBTT-based activities conducted within students’ social networks on their language learning and well-being. The data were collected for 6 years (2010-2015) from students’ action logging and case studies. Language students taking Murphey’s English classes were asked to self-report their experiences and to write reflections after their WBTT-based activities. The qualitative data indicated that both the students in the teaching role and the people who received their lessons deepened their understanding of both the content (message) and form (target language), forming affinity spaces in different social contexts both in and out of class. Most importantly, it was recognized that both groups of people were able to experience exciting learning or teaching rushes through the engagement in the activities.
Ambiguidades da politização do consumo:
Authors: Tanaka Jennifer , Portilho Fátima
Published: March 2020

A partir dos anos 2000, a alimentação passou a ocupar o núcleo das ações do Movimento dos Pequenos Agricultores (MPA), que iniciou a construção de alianças com consumidores urbanos. O artigo analisa a incorporação da estratégia de politização do consumo pelo MPA, mapeando seus discursos e as ações desenvolvidas no “Raízes do Brasil”, um espaço que comercializa alimentos da agricultura camponesa, inaugurado pelo MPA, no Rio de Janeiro, em 2017. A incorporação de estratégias de politização do consumo pelo MPA é um fenômeno consistente, com destaque para a desfetichização da mercadoria e o fomento ao buycott, reforçando o papel ativo de consumidores urbanos. No entanto, as alianças com consumidores urbanos se constituem tanto uma oportunidade quanto um desafio para o MPA. Tal processo é permeado por ambiguidades, desconfortos e hesitações relacionados às dificuldades em lidar com o consumidor como ator político.
Metodología de la Investigación Social
Authors: Herrera Luis Carlos
Published: March 2020

El presente ensayo trata de una de las más importantes discusiones teóricas abstractas de la metodo-logía de la investigación, específicamente en las ciencias sociales: las similitudes y diferencias en lo que se conoce como “datismo” y “dadaísmo”. En primera instancia se construye la caracterización epistemológica de cada una. Luego la argumentación sobre la postura asumida acorde al tema y, por último, el cómo esta discusión teórica impacta en la construcción de un diseño de investigación. Desde las ciencias sociales, una de las principales preocupaciones está en la capacidad de inferir resultados, y que esa inferencia de alguna manera permita hacer generalizaciones. Esta inquietud es el eje central del positivismo. No obstante, hay otra vertiente llamada constructivismo en la cual lo importante no es la inferencia, si no la comprensión del hecho social. En medio de esto es que desarrollamos la discusión en torno al datismo y dadaísmo, finalizando con un ejemplo de propuesta de investigación que estamos desarrollando actualmente.

Published: March 2020

In order to study the molecular biological markers of the tumor in patients with endometrial cancer stages I−IV, the patients who received a combined treatment at the Department of Oncological Gynecology at the State Institution "Grigoriev Institute for Medical Radiology" were surveyed. The study has demonstrated that in the patients with advanced endometrial cancer, the expression rate of molecular biological markers and ER and PR receptors depends on the histological shape of the tumor. In adenocarcinomas with a high degree of differentiation, the value of both positive and negative VEGF was observed in equal percentages, against the background of high Bcl−2 expression, negative mt p53 expression, and negative or moderate proliferative activity. In patients with adenocarcinoma with moderate degree of differentiation, the value of positive VEGF was observed three times more often than negative one, against the background of a high Bcl−2 expression, negative mt p53 expression and moderate proliferative activity (Ki67). In the patients with low−grade adenocarcinoma endometrium, both positive and negative VEGF were equal in percentage, against the background of high Bcl−2 expression, negative mt p53 expression, and positive proliferative activity. In adenocarcinomas with high and moderate degree of differentiation, the positive status of ER and PR is more often observed, and, conversely, in the patients with low−differentiated adenocarcinoma their negative status was found. It has been revealed that the level of expression of the investigated molecular biological markers and ER and PR receptors in tumors of the patients with endometrial cancer differed depending on the occurrence of relapse. This fact can be used to determine the risk of endometrial cancer recurrence.

Key words: endometrial cancer, molecular biological markers, relapse, expression.

The interview questions were based on the guidelines given in recent examinee handbooks, the aim being to see to what extent a live interview with an expert would confirm the preparation points and perhaps shed more light on their implications.
The mechanization of teaching: Teachers’ metaphors and evaluation in Japanese tertiary education
Authors: Burden Peter
Published: March 2020

Twelve ELT university teachers reflected, through using metaphors, in interviews about the use of Student Evaluation of Teaching surveys (SETs) in their respective universities. Studying teachers' metaphor reveals their first-hand experience of how they were affected in their teaching by SETs. Metaphors suggest that SETs do not match teachers’ conceptions of teaching as an art. Such evaluation has caused relations between teachers, administrators, and students to fracture due to competitive ranking. While participants accept formative evaluation as a necessary process to give insights to teachers, they wish for a more open, improvement-focused, cooperative, specific evaluation. They want more teacher involvement and more dialogue between teachers to discuss the results of SETs to aid the reflective process for change. 大学でELT担当の12名の教師にインタビューを実施し、各自の大学での学生による授業評価（SETｓ）についてメタファー（比喩）にて述べてもらった。教師のメタファーは、学生による授業評価（SETｓ）で各々の教え方にどのような影響があったかの率直な考えを表している。メタファーは、学生による授業評価（SETｓ）と教師側の技術としての‘教える’という考え方は合致しないということを示唆している。このような評価は、競争的な評価をすることで教師側・大学当局側・学生側の関係を壊している。被験者（つまり学生）側が必要な過程として形成された評価を受け入れて、教師側に新たな教育的ひらめきをもたらさなければならない、その一方で被験者側はより開放された、改善を目的とした、連携された、特定の評価を望むのである。被験者側のコメントでは、教師側の更なる向上の必要性、また教師側と学生による授業評価（SETｓ）の結果について意見交換をし、授業の変化をもたらせたいとしている。

Published: March 2020

A number of bacterial glycans are specific markers for the detection and the serological identification of microorganisms and are also widely used as antigenic components of vaccines. The use of gold nanoparticles as carriers for glyco-epitopes is becoming an important alternative to the traditional conjugation with proteins and synthetic polymers. In this study, we aimed to prepare and evaluate in vivo glyco-gold nanoparticles (glyco-GNPs) bearing the terminal-branched hexaarabinofuranoside fragment (Ara6) of arabinan domains of lipoarabinomannan and arabinogalactan, which are principal polysaccharides of the cell wall of Mycobacterium tuberculosis, the causative agent of tuberculosis. In particular, we were interested whether the antibodies generated against Ara6-GNPs would recognize the natural saccharides on the cell surface of different mycobacterial strains. Two synthetic Ara6 glycosides with amino-functionalized spacer aglycons differing in length and hydrophilicity were directly conjugated with spherical gold nanoparticles (d = 15 nm) to give two sets of glyco-GNPs, which were used for the immunization of rabbits. Dot assays revealed cross-reactions between the two obtained antisera with the hexaarabinofuranoside and the 2-aminoethyl aglycon used for the preparation of glyco-GNPs. Both antisera contained high titers of antibodies specific for Mycobacteria as shown by enzyme-linked immunosorbent assay using M. bovis and M. smegmatis cells as antigens while there was only a weak response to M. phlei cells and no interaction with E. coli cells. The results obtained suggest that glyco-GNPs are promising agents for the generation of anti-mycobacterial antibodies.

Published: March 2020

We propose the use of gold nanoparticles grown on the surface of nanoporous TiO2 films as Surface Enhanced Raman Scattering (SERS) sensors for the detection of 17β-estradiol. Gold deposition on top of TiO2 surfaces leads to the formation of nanoparticles, which plasmonic properties fit the requirements of a SERS sensor well. The morphological and optical properties of this surface were investigated. Specifically, we demonstrated that the TiO2 background pressure during pulsed laser deposition and annealing conditions enabled the formation of a variety of Au nanoparticles with controlled size, shape and distribution thus resulting in a versatile sensor. We have exploited this surface for the detection of 17β-estradiol, an emerging contaminant in environmental waters. We have found a limit of detection of 10 nM with a sensitivity allowing dynamic range of five orders of magnitude (up to 100 µM).

In the treatment of its fixed assets, PT Bahagia Jaya Sejahtera still has a mismatch. The discrepancy is in the recording of the acquisition price of the fixed assets, the company still records the fixed assets based on the purchase price only, while the costs associated with the fixed assets are charged as costs in the period of occurrence, which are charged as administrative and general costs. In addition to those expenses intended to condition the fixed assets so that they are always ready to be used, recorded as administrative and general expenses in the current period, for example in the purchase of fixed assets in the form of machines, PT Bahagia Jaya does not add these costs to the acquisition price of fixed assets. And when calculating depreciation of fixed assets, companies tend to use the straight-line method, whereas there are other methods that can be used to support the company's earnings. From the results of this analysis, it will be known the comparison of the acquisition price of fixed assets and cost allocation as well as the amount of depreciation costs between the company and the SAK regulations. The results of this analysis are presented in the form of comparative financial statements to determine the effect on financial statements. In the income statement, administrative and general costs are recorded to be too high, due to costs that should add to the acquisition value of fixed assets but instead are allocated to administrative and general costs.Thus, to present financial statements especially in Asset accounting treatment, it should be understood and implemented a fixed accounting policy in accordance with financial accounting standards.

Un mundo nuevo e imposible. El Incidente y las consecuencias políticas del espacio cinematográfico
Authors: Aguilar Alcalá Sergio José
Published: March 2020

El Incidente (2014), el primer largometraje del cineasta mexicano Isaac Ezban, es un filme de fantasía que cuenta dos historias paralelas en las que un grupo de personajes quedan atrapados en espacios “imposibles” por décadas. A través de sus escenarios claustrofóbicos, la película toma postura respecto a las rutinas diarias, aburridas y exhaustivas de las ciudades, y el fantasma que acosa con nuestro deseo de vivir otra vida, de haber tomado otras decisiones, de haber hecho las cosas diferentes. Cada construcción del mundo real habita entre construcciones de mundos posibles, así que cada sujeto habita entre diferentes y posibles versiones de sí misma/o. Este texto examina, con secuencias seleccionadas y usando herramientas teóricas de la arquitectura crítica y la crítica del ciberespacio, cómo es que diferentes versiones de nosotros habitan en las ciudades, y por qué es importante reconocerlas para así imaginar diferentes, y mejores, ciudades y vidas.
Algunos usos del documental y la memoria: Un estudio de caso en la obra del documentalista cubano Santiago Álvarez.
Authors: Lazo Pasto Orlando Rafael
Published: March 2020

Resumen: La producción documental a través de la historia del cine ha sido vista desde una dualidad de enfoques, por un lado, como elemento de traducción fiel de una realidad y por otro con una visión que contradice esto, aduciendo que la realidad representada, está matizada por miradas y puntos de vistas.  Teniendo como base esta premisa dual, el trabajo tiene como objeto imbricar el carácter del documental, como proceso de reconstrucción de una heredad histórico-espacial, pero también denotando ese espacio sociocultural de signos y significados inserto en un producto audiovisual de corte documental. Para ello se toma como estudio de caso la obra de Santiago Álvarez, documentalista cubano de alta talla a nivel latinoamericano y mundial, que marcó un hito en el desarrollo de este género, por la creatividad sus propuestas documentales.

Texture Based Classification of Malaria Parasites from Giemsa-Stained Thin Blood Films
Authors: Tantisatirapong Suchada , Preedanan Wongsakorn
Published: March 2020

Quantification of parasitemia is an important part of a microscopic malaria diagnosis. Giemsa-stained thin blood smear is the gold standard method for detecting malaria parasite enumeration. However, manual counting reveals the limitations of human inconsistency and fatigue, as well as the unreliability of accuracy and non-reproducibility. Inaccurate parasitemia affects clinical diagnosis and therapeutic procedure. Automated quantification is therefore useful to improve the performance of quantifying parasite density. In this paper, the texture-based classification approach is investigated. The methods consist of the following processes: pre-processing, segmentation, feature extraction and the classification of erythrocytes. The pre-processing is applied for image conversion and enhancement. The segmentation combines local adaptive thresholding, morphological process and watershed transform to extract red blood cells, separate touching and overlapping cells. Texture analysis is performed to establish parameters obtained from first-order, second-order and higher-order statistical analysis and wavelet transform. Two feature selection approaches, the sequential forward selection method and sequential backward elimination method, integrated with a support vector machine classifier are examined to obtain the optimal feature set for identifying the Plasmodium falciparum stages. We found that gray-level co-occurrence matrices based textural features were highly selected. The optimal feature set selected by the sequential forward selection yields lesser number of features and tends to give a higher degree of accuracy than the feature set selected by sequential backward elimination. The proposed method produces 98.87% accuracy for binary classification, 99.56% accuracy for ring stage classification, and 99.48% accuracy for tropozoite stage classification. Grey-level co-occurrence matrices based texture analysis is the dominant method compared to first-order and higher-order statistical texture analysis as well as wavelet transform.
