Safety Risk Management In Large Scale Engineering Based On Model Predictive Control
Authors: Jianfeng Qiao 
Published: January 2015

Abstract
Safety risk during the construction of a Large Scale Engineering (LSE) project can be avoided through safety education, following a correct procedure and using an engineering method. In order to ensure that LSE works in a safe state, some parameters need to be restricted to a certain range. Besides, in order to apply the former control for the predictive values, a Model Predictive Control (MPC) theory is suggested to be used for safety risk controlling. We share a MPC work flow and detail calculation steps of the rolling optimization, feedback correlation and constraint control, and a mean time gradient decent method is used during the optimization calculation iteration steps. At the end, regarding the resource allocation issue in the ship-lift engineering construction area of “Three Gorges” we verify how MPC works; and the numeric results show MPC’s efficiency. We can see that MPC might have important future in safety risk management of LSE, because as long as the model can be predictive, regardless of an accurate mathematical model of the system, MPC can control a dynamic and uncertain system very well, which is also a characteristic of the safety risk of LSE.

Published: January 2015

Abstract
In connection with the problem that the food processing information system is poor due to the absence of knowledge acquisition and a knowledge selfupdating function, a knowledge acquisition approach, based on a Support Vector Machine (SVM) is proposed. First, the approach establishes a set of predicted samples for the relationship between the food processing parameters and product quality; then it uses discretization of the continuous attributes, attributes reduction and a rule extraction algorithm of SVM to automatically acquire predicted knowledge from a large number of predicted sample sets. After that it saves the predicted knowledge in the knowledge base of an expert system; finally, the method realizes extraction of the knowledge about the food processing process based on the inference engine, which greatly enhances the efficiency and applicability of the acquired knowledge in an online aided decision system of food processing quality and safety.
Homogeneous Magnetic Field Source For Attenuated Total Reflection
Authors: Lesňák Michal , Staněk František , Pištora Jaromír , Procházka Jan 
Published: January 2015

Abstract
The paper is focused on the study of two-dimensional magnetic field distribution used for an analysis of samples containing magnetically active films by means of the Attenuated Total Reflection (ATR) method. The design of a proposed electromagnet and the magnetic field model computation are presented together with the results obtained from magnetic field distribution measurement. The ATR method can provide information about a thin film thickness, refractive index, and attenuation in addition to the perfunctory coupling of an optical wave into and off a waveguide [1, 2]. The prism coupling conditions are determined for magnetic structures with induced anisotropy.
The prism - a film coupler is located in the central cavity of a magnetic yoke. By current switching in the coils, we can change the amplitude and magnetic field direction in order to modulate the induced anisotropy in a thin film with magnetic ordering. By the in-plane modulation of the magnetization direction in the samples, we can change the rotation and elasticity of outgoing light.

“Die hart ’n droë blaar”: Verlies, rou en melancholie in Olga Kirsch se Afrikaanse poësie / “The heart a dry leaf”: Loss, Mourning and Melancholia in Olga Kirsch’s Afrikaans Poetry
Authors: Viljoen Louise 
Published: January 2015

Abstract
Reading Olga Kirsch’s Afrikaans poetry, one is struck by the important role that the experience of loss occupies in her oeuvre. It is evident in the first two volumes of poetry she published while still living in South Africa, as well as in the five volumes she published after emigrating to Israel in 1948. Because her poetry, especially the volumes written in Israel, exudes an air of melancholy, this article uses Freud’s writings on loss, mourning and melancholia, as well as the historical tradition preceding his work, as a guideline in exploring the way in which the experience of loss, mourning and melancholy is portrayed in Kirsch’s oeuvre. The article focusses on the way in which loss is portrayed in her poetry: her sense that the Jewish experience of loss over the centuries forms part of her history and identity, the way in which she experiences the loss of South Africa and the language Afrikaans in which she is best able to express herself poetically when she emigrates to Israel, the way in which the loss of her father and mother at different times in her life affected her, her feeling that her experience of loss and the ensuing melancholy are carried over to her children.
Jan Greshoff se ‘aanval’ op Olga Kirsch as een van die hoofredes vir haar emigrasie: ’n Psigoanalitiese beskouing / Jan Greshoff’s ‘Attack’ on Olga Kirsch as One of the Main Causes of Her Emigration: A Psychoanalytical Point of View
Authors: Minnaar Thomas 
Published: January 2015

Abstract
The poet Olga Kirsch left South Africa permanently for Israel in 1948. It is evident from her poetry that her Zionism, opposition to the racism of the National Party and a failed love played a role in her decision. This article focuses on another reason - a public attack by the Dutch critic Jan Greshoff in an Afrikaans literary magazine in 1946. Using concepts from psychoanalytical theories around borderline and narcissistic personalities, as well as the effect of emigration, Kirsch’s actions are examined as a reaction to narcissistic wounding. Investigating Greshoff’s criticism gives insights into the poet’s actions and explains the hiatus before she started publishing again in Afrikaans from 1971. It is stated that the poet is not considered to be a narcissist as her oeuvre is a testimony to her empathy with others, but the healthy narcissism needed in building one’s self-esteem underwent a severe blow when Kirsch lost the man she loved and was humiliated so devastatingly by the great Dutch critic.
Olga Kirsch se posisie in die Afrikaanse literêre sisteem (1900-1978) / Olga Kirsch’s Position in the Afrikaans Literary System (1900-1978)
Authors: Senekal Burgert 
Published: January 2015

Abstract
Centrality and marginality are important concepts in polysystem theory, and also in network theory. This article examines Olga Kirsch’s position in the Afrikaans literary system by taking into account data spanning from 1900 to 1978. Overall centrality is discussed from the perspective of network theory and related to polysystem theory, and the concept is also applied to the literary system through the use of the Fruchterman and Reingold (1991) force-directed layout algorithm. It is indicated that Kirsch is positioned on the edge of the core or in the semicore, mainly because there are not so many people from the core who had paid attention to her works, but also because she, according to this data set, did not write on the works of others. It is also indicated which important critics, literary scholars and literary historians paid attention to her works, which contributes to her not being positioned on the periphery.

Mammary tuberculosis is a rare entity in western countries but a continuing problem in endemic areas like Bangladesh. Its clinical patterns and treatment strategies are changing day by day. In this study we showed our clinical experience on 50 cases of mammary tuberculosis. This is a prospective nonrandomized observational descriptive study. A total of 50 consecutive adult female patients with no other co morbid diseases and who were diagnosed cytologically or histologically as case of mammary tuberculosis were enrolled in the study over a period of 04 years since 2006 to 2010 in general surgical unit of Chittagong Medical College Hospital and Chittagong general hospital. The average ages of presentation were 38 years. Ten(20%) patients were lactating at the time of presentation and six(12%) patients were nulliparious. 40(80%) patients had breast lump at presentation. Among them 20(40%) presented with multiple sinuses with lump,10(20%) had abscess with lump,05(10%) had abscess drainage scar with underlying lump and 05(10%) presented with isolated breast lump. 06(12%) presented with multiple sinuses with abscess formation. Another 04(8%) patients had multiple sinuses only at presentation. Ten (20%) had constitutional symptoms in the form of fever, weight loss and night sweat. Twenty (40%) had axillary lymphaedenopathy in association with breast lesion. Diagnosis were confirmed by cytological and or histological findings of epitheloid granulomas.All patients were given antitubercular chemotherapy ( 9 months regimen) in combination with surgical intervention (45 out of 50 cases) as necessary in the form of excision of masses, incision and drainage of abscess and sinectomy. Mammary tuberculosis is a continuing problem in developing countries. Presentation may mimic benign lesion or carcinoma of the breast. Diagnosis can be made on high index of suspicion in endemic areas. Cytological or histological findings of granulomatous inflammation consisting of caseation necrosis, epitheloid cell and Langhans giant cell can give definitive diagnosis. Treatment is by anti tubercular chemotherapy with or without surgical intervention where necessary.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i2.21063

Published: January 2015

Tumor markers are often very helpful to diagnose, staging, treatment planning and following up of the cancer patients. But still deluge of tumor markers often presents an unethical excess laboratory experience of the patients which is neither helpful nor necessary. So this is the appropriate time to think again about the accuracy of the tests to measure the parameters without error, the precision of the tests to measure the parameter they intend to measure. Our acceptance or rejection of a tumor marker testing must be guided by statistical validity of the test with an appropriate and knowledge based cut-off value determination. Statistical analysis of the tumor marker should be proportional to the empirical judgments of the clinicians. For the clinicians it is a duty to advise not only for all the tests needed for appropriate treatment but also advise only the tests those are direly needed. Otherwise tumor markers which should be an important weapon to fight against cancer will be another burden over the cancer patients. In this article we intended to focus on the technical and statistical side of different tumor marker test most concentrated around the breast cancer tumor markers. But still this review may be concerned relevant and universal for each and every cancer type and tumor markers.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i2.21080

Published: January 2015

Introduction: Fractures & Orthopaedic trauma to the new born baby during birth are not uncommon. Immediate unavailability of an Orthopaedic surgeon adds to the embarrassment of the Obstetrician, and creates tension of the parents. Simple early measures can be taken to ease the situation. This paper is prepared with the intention of discussing some of the more common situations & their immediate management.Materials & Methods: Few patients with different birth trauma were treated in Dhaka Medical College Hospital & some other government & non government hospitals during January 2009 to June 2014. Different types of fractures, epiphyseal separation, Obstetric brachial Plexus palsy, Congenital Muscular Torticolis were treated by traction, splinting, plasters, physiotherapy & other conservative methods. Patients were followed up for long term assessment.Results: Results of fracture management were excellent with early union of all the cases. Soft tissue trauma, like Congenital Muscular Torticolis & Obstetric brachial plexus palsy treatment yielded variable results owing to the depth of their involvement. Conclusion: Despite all the measures, trauma to the newborn baby still happens worldwide. Situation in Bangladesh is probably still worse. Early management of birth trauma is essential to avoid a lifelong disability. Immediate management may be started by the obstetrician before referring the patient, which will improve the final outcome.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i3.21025
