Analysis and classification of myocardial infarction tissue from echocardiography images based on texture analysis

Texture analysis is an important characteristic for automatic visual inspection for surface and object identification from medical images and other type of images. This paper presents an application of wavelet extension and Gray level cooccurrence matrix (GLCM) for diagnosis of myocardial infarction tissue from echocardiography images. Many of applications approach have provided good result in different fields of application, but could not implemented at all when texture samples are small dimensions caused by low quality of images. Wavelet extension procedure is used to determine the frequency bands carrying the most information about the texture by decomposition images into multiple frequency bands and to form an image approximation with higher resolution. Thus, wavelet extension procedure offers the ability to robust feature extraction in images. The gray level co-occurrence matrices are computed for each sub-band. The feature vector of testing image and other feature vector as normal image classified by Mahalanobis distance to decide whether the test image is infarction or not

The duty of care for negligents misstatements / A. Razak Salleh

As part of the requirement for the obtainment of the Diploma in Law, every Law students who are in their final semester are require to do a Project Paper. The topic for the Project Paper are chosen by the students themselves on condition that it get approval from the School of Law. I have chosen the topic of Duty of Care for Negligents Misstatements, because I find that the topic is very fascinating and there is a lot of material been written about the topic. In writing the topic I was compelled to look at English and commonwealth sources, especially those of Australia. I have try to keep a proper balance between the need to discuss the topics considered essential and to keep the 'paper' to a reasonable length

Discriminative Tandem Features for HMM-based EEG Classification

Abstract—We investigate the use of discriminative feature extractors in tandem configuration with generative EEG classification system. Existing studies on dynamic EEG classification typically use hidden Markov models (HMMs) which lack discriminative capability. In this paper, a linear and a non-linear classifier are discriminatively trained to produce complementary input features to the conventional HMM system. Two sets of tandem features are derived from linear discriminant analysis (LDA) projection output and multilayer perceptron (MLP) class-posterior probability, before appended to the standard autoregressive (AR) features. Evaluation on a two-class motor-imagery classification task shows that both the proposed tandem features yield consistent gains over the AR baseline, resulting in significant relative improvement of 6.2% and 11.2 % for the LDA and MLP features respectively. We also explore portability of these features across different subjects. Index Terms- Artificial neural network-hidden Markov models, EEG classification, brain-computer-interface (BCI)

Malay Mathematics Based on Terengganu Inscription

We exhibit the Malay Mathematics in the 14th century Terengganu Inscription dated 702H, that is 1303. There are several mathematical elements that we classify as Malay numbers (cardinal and ordinal), units of measurement, position (location and position in a family), elements of logic, and time (day, month and year). We also give an equivalent amount of fine imposed to convicts as listed in the inscription

BROWN SPOT CAUSED BY CURVULARIA SPP., A NEW DISEASE OF ASPARAGUS

The distribution, aetiology and symptomatology of a new disease on asparagus ferns, which we have termed brown  spot,  is  described.  Descriptions  of  and  a  key  to  identification  of  the  causal  organisms,  Curvularia brachyspora, C. eragrostidis, C. lunata and C. pallescens, are also presented. Pathogenicity tests showed that C. lunata was the dominant and most virulent of the four species. Inoculation with conidial suspensions or mycelial transfers through wounded ferns were more effective in inducing the disease than inoculations on unwounded ferns. This is the first record of C. brachyspora in Malaysia and the first report of this disease on asparagus.Key words:  Malaysia/Plant diseases/Brown spotJCurvularia brachyspora/Curvularia eragrostidts/Curvularia lunata/Curvularia pallescens/Asparagus

Bilingual first language acquisition in Malay and English : a morphological and suprasegmental study in the development of plural expressions in a bilingual child

This thesis investigates the development of plural marking in a child raised in Malay and English simultaneously, from the morphological and prosodic perspective. For the morphological plural development, the child’s plural acquisition is analysed within the Processability Theory (PT) framework de Bot (1992) de Bot (1992) thus widening PT’s typological range of application to a language such as Malay, which belongs to the Austronesian family (Dryer & Haspelmath, 2013). PT has been tested for morphological development in L2 English (Di Biase, Kawaguchi, & Yamaguchi, 2015; Johnston, 2000) and several typologically different languages as well as bilingual first language acquisition (BFLA) such as Japanese-English (Itani-Adams, 2013). However, PT has not been empirically tested for any language of the Austronesian family nor in a Bilingual First Language Acquisition (BFLA) constellation involving Malay and English. The Malay-English language pair is interesting because of the remarkably different linguistic mechanisms used for encoding plurality in the two languages; morphologically, Malay marks plurality through distinct forms of reduplication such as rumah-rumah ‘houses’, buah-buahan’ (plural form of buah ‘fruit’) and bukit-bukau ‘hills’ (Sew, 2007). In contrast, English uses morphological inflections -s suffixed to the stem, e.g., cat/cats, dog/dogs, book/books (Carstairs-McCarthy, 2002). Malay reduplication, as previously shown, involves more than a single word, however, functionally speaking it is equivalent to one word plus a marker of plurality. Thus, prosodic mechanisms play a crucial role in distinguishing between mere repetition and grammatical reduplication in Malay (Gil, 2005). Since plurality is expressed very differently in each language, this study investigates how a bilingual child develops simultaneously two grammatical systems. The participant in this research is a female child named Rina, who was raised in Malay-English environment from birth. This investigation comprises of two parts; first is the longitudinal investigation of her plural acquisition from age 2;10 to 3;10. During this period, Rina was living in Australia, where the environmentally predominant language was English. The second complementary part is an investigation of Rina’s plural marking systems at age 4;8 when she had returned to Malaysia, where the predominant environmental language was Malay. For the longitudinal study, the database for the analyses was obtained from separate Malay and English recording sessions, which were conducted weekly from age 2;10 to 3;10. Likewise, the data for Rina’s plural expression at 4;8 was also obtained from separate Malay and English environment recordings. For the morphological plural development, results indicate that Rina developed two different systems to mark plurality in Malay and English. Her plural marking developed in the sequence predicted by PT. However, though she clearly distinguished the two languages, bidirectional influences from English to Malay and Malay to English were found in the corpus, both in the longitudinal study as well as at age 4;8. In the longitudinal study, it was found that in expressing plurals in Malay and English, Rina used various linguistic devices: one of the predominant strategies she employed in both languages was iteration, a strategy in which Rina expressed more than one objects by repeating the lexical item according to the number of individuated entities (hence four cats would be expressed as cat cat cat cat). Reduplication, the target grammatical Malay plural, only emerged at 3;8. Thus, we examine the prosodic development of the child’s iteration up till the emergence of reduplication. Findings indicate that the development from iteration to reduplication is gradual; the main acoustic correlate that she employed during the longitudinal study was final-syllable lengthening. She only began differentiating various prosodic mechanisms (such as pausing, duration and pitch) to distinguish repetition and reduplication in her plural marking at age 4;8. This study offers a new perspective on the interplay between the two languages in the early stages of grammatical development in a bilingual child. The specific features of plurality in Malay and English and how they develop in the bilingual child may shed light on the applicability of PT to BFLA. Also, the link between the child’s morphological development and prosodic mechanisms show that in acquiring the prosodic structures of reduplication, Rina creates partial and increasingly specific analyses of the grammatical forms, gradually approaching the conventional adult form

Hybrid features-based prediction for novel phish websites

Phishers frequently craft novel deceptions on their websites and circumvent existing anti-phishing techniques for insecure intrusions, users’ digital identity theft, and then illegal profits. This raises the needs to incorporate new features for detecting novel phish websites and optimizing the existing anti-phishing techniques. In this light, 58 new hybrid features were proposed in this paper and their prediction susceptibilities were evaluated by using feature co-occurrence criterion and a baseline machine learning algorithm. Empirical test and analysis showed the significant outcomes of the proposed features on detection performance. As a result, the most influential features are identified, and new insights are offered for further detection improvement

Fire safety management in heritage buildings: the current scenario in Malaysia

In Malaysia, there are many heritage buildings with an architectural and historical significance that influenced by several architecture styles including a traditional Malay architecture, the Portuguese architecture, the Dutch architecture, and the architecture styles brought by British (e.g. Moorish, Tudor, Neo-Classical and Neo-Gothic). Most of them are worthy to be listed as Heritage Buildings or National Heritage Buildings under the National Heritage Act 2005 (Act 645). The Malaysian government is undertaking many efforts to promote conservation and preservation of heritage buildings in the country. Some of the buildings have been changed to different functions from its original (adaptive-reuse) such as into museums, libraries, offices or hotels. It is however, in the past few years there are few priceless heritage buildings were badly damaged or burnt down by fire includes the People Museum, Melaka (2001), Rumah Pak Ali , Gombak (2003) and Sarawak Club, Kuching (2006). In one case, it was given a total loss approximately up to MYR 5 millions. Fire is one of the greatest threats to heritage buildings not only to the building’s occupants but also to the building’s fabric and contents. Heritage buildings are irreplaceable but vulnerable to fire as there is a combination of several factors: large scale buildings; flammable priceless contents; large numbers of visitors; and existing structures weak on fire resistance. Unfortunately, until today, there are relatively no sufficient legislations or guidelines on fire safety for heritage buildings in Malaysia. In fact, the Fire and Rescue Department of Malaysia (FRDM) stressed the safety of life is the ultimate principle of fire safety in a building. Property protection which includes protection to building’s fabrics and contents of heritage buildings is not really been prioritised. The purpose of this research is to investigate the current fire safety management in heritage buildings in Malaysia through a series of interview and observation surveys. In this research, thirty seven heritage buildings have been surveyed as a building sampling. The finding found that most of the buildings are still having a poor fire safety management. From the survey, seventeen leading fire safety management problems in the buildings have been identified
