| Abstract |
Read more…The research project was designed to study the levels of oxidative stress and antioxidants status in β-thalassemia patients with transfusional iron overload and chelation therapy as a central pathological process under indigenous conditions. 100 β-thalassemic patients were included in the research project. Serum levels of oxidative stress parameters (total oxidant status and malondialdehyde) and antioxidant parameters (total antioxidant status, vitamin E, C and β-carotene) were studied. These findings were compared with 100 healthy controls of age below15 years. Blank blood specimen was collected from both healthy and thalassemic patients. Total oxidant status, malondialdehyde and total antioxidant status was determined with the help of spectrophotometer while vitamin E, C and β-carotene was determined with the help of HPLC and software LC Solutions. A significant increase in the levels of malondialdehyde (p<0.000) and total oxidant status (p<0.001) was observed. A significant decrease in the levels of total antioxidant status (p< 0.001), vitamin E (p<0.000), C (p<0.000) and β-carotene (p<0.000) was recorded. This suggests that oxidative stress mechanism play an important role in pathogenesis of β-thalassemia. The combination of effective iron-chelator with antioxidant can be very helpful in the regulating the antioxidant status of patients with β-thalassemia and related complications in β-thalassemia still need further study. |

| Title | Contribution of technical vocabulary & general vocabulary to ESP reading comprehension |
| Paper ID | ds4XQ/NA |
| Keywords | technical vocabulary \ngeneral vocabulary \nESP reading comprehension |
| Abstract |
Read more…The purpose of this study was to investigate the contribution of technical vocabulary & general vocabulary to ESP reading comprehension. In this study 2 groups of BA students were selected majoring English translation and Nursing fields of study. These students were divided into two equal groups. Both groups received a first test including 60 multiple choice items, 30 general vocabulary items from a TOEFL test and 30 technical vocabulary items in nursing sciences to make sure that the students in English translation had better general vocabulary & students in nursing sciences had better technical vocabulary, and a second test including 30 ESP reading comprehension items from MA entrance examination of universities to capture the probable differences between the effect of technical vocabulary & general vocabulary to ESP reading comprehension. Then, with the help of T.Test the data were computed. The result rejected the null hypothesis and indicated that the difficulties which ESP students encounter in their reading comprehension arise not so much from lack of technical vocabulary knowledge but from lack of general vocabulary knowledge. The findings of the present study can have theoretical as well as pedagogical implications for teachers, students, and syllabus designers. |

| Title | QUANTITATIVE ANALYSIS OF HRCT IMAGES USING KNN CLASSIFIER |
| Paper ID | 7Fiim |
| Keywords | Emphysema,Local binary patterns, Quantitative computed tomography, Texture analysis, Tissue classification. |
| Abstract |
Read more…This paper aims at improving quantitative measures of emphysema in computed tomography images of lungs. Pulmonary Emphysema is a chronic obstructive lung disease which is characterized by limitation of air flow. Detection and Quantification of emphysema is important, since it is the main cause of shortness of breath and disability in Chronic Obstructive Pulmonary Disease. Current standard measures like Relative Area method rely on a single intensity threshold on individual pixels, ignoring any interrelations between pixels. HRCT is a sensitive method for diagnosing emphysema, assessing its severity, and determining its subtype. In this project texture based classification system is used. A study is \nperformed by choosing Local binary Pattern (LBP) as texture feature and classification is performed using KNN classifier. Classification accuracy and quantification shows that KNN classifier performs better when LBP is used as texture feature in determining Pulmonary Emphysema. |

| Title | An analysis of broadcast authentication and security schemes in wireless sensor networks |
| Paper ID | boOwZ |
| Keywords | base station; elliptic curve diffie-hellman; signature; timed efficient stream loss-tolerant; wireless sensor networks |
| Abstract |
Read more…Wireless Sensor Networks (WSNs) are susceptible to various attacks as they are placed in hostile environments. Several security and authentication mechanisms are proposed for in terms of key exchange mechanisms, handshake protocols, and other routing protocols. The proposed triple key based broadcast authentication protocol is compared with the several other existing security schemes in WSN. The proposed triple key based broadcast authentication scheme works upon TESLA (Timed Efficient Stream Loss-tolerant Authentication) protocol and ECDH (Elliptic Curve Diffie-Hellman) key agreement scheme. The proposed WSN authentication performs better compared to other security schemes, in terms of accuracy, detection of attacks, resiliency, memory consumption, nodal detection, and average of total transmission energy consumed per node. |

| Title | The Necessities, Impairs and Constrains of Nullification of Criminal Immunity of the Head of States |
| Paper ID | 0LyGN/NA |
| Keywords | Immunity, Head of states, International crimes, Campaign against not-punishment |
| Abstract |
Read more…Trail and punishment of the head of states that commit international crimes were faced with many impairs\nand problems. Among these, the most important legal impair is criminal immunity. The history has shown that these\naccused have generally had s sufficient immunity and not ever s submit to justice. Nullification of the criminal\nimmunity of the head of states is necessary because of matters including public international order, international\npeace and security, domestic international order, prevention of non-punishment of the criminals and deterrence so\nthat prevent of non-punishment of the criminals. Effective implementation of prosecution and trail of the head of the\nstates and nullification of their immunity deals with some impairs, constrains, costs and challenges. Among these\nimpairs are the non-existence of necessary and suitable statutes, non-willing of states and marshaling evidence.\nThese impairs should be identified and rectifies by states. This paper is designed in two parts. The first one deals\nwith necessities of nullification of the criminal immunity and the second part analysis the impairs and constrains of\npunishment of the head of states. |

| Title | Introduction of Balance Parameter in Performance Improvement of Text-Independent Speaker Recognition Systems |
| Paper ID | 1D0R8/NA |
| Keywords | RelifF, support vector machine,balance parameter, error rate, speaker recognition system |
| Abstract |
Read more…Speaker recognition systems are some kind of biometric systems used in security applications based on remote control phones. This paper presents an approach to balancing the increase in the number of speakers, runtime and error rate of the system. The efficiency of these systems often depends on a particular number of people.With a sudden increase in the number of speakers in terms of time, the recognition error rate experiences a sharp rise. This paper introduces a parameter to select the optimal number,noisy samples for training and testing the Support Vector Machine (SVM) classifier.This approach aims to significantly increase learning speed andto test speaker recognition systems by setting noisy parameters for learning the model and recognizing people. In the first stage,we use the ReliefF algorithm to select the optimal feature subset, then the SVM classifier to achieve better accuracy in recognition by changing existing SVM kernels and automatically setting the balance parameter during training. This method is evaluated based on the accuracy/(Total time ) ratio. The results show that by setting the balance parameter compared with non-setting, above ratio always shows a higher value. |
