This thesis presents a novel architecture for native process migration (PM) in wireless sensors networks (WSN) without the use of virtual execution environment. Resources in WSN are scarce, therefore creating a virtual execution environment for processes so that they can be migrated, put an extra burden on already constrained resources. The proposed architecture for process migration allows live native processes to be migrated during execution. The process migration architecture takes migration decisions by continuously monitoring resources including remaining battery life and free memory space on a node. The architecture is suitable for networks with fewer expensive sensor nodes as it allows for better utilization of network resources. Transferring a live executing process helps in meeting processing demands dynamically, improves fault tolerance and resource utilization, and allows easier network management in WSN. The proposed architecture supports resourcing monitoring, request broadcasting and response collection, target node selection, process code and state transfer, and restoration of native process at the target node. Implementation of proposed architecture has been successfully tested on COOJA simulator and a test-bed of TelosB motes. The final implementation has been compared to agent based systems and virtual machine architectures. It shows a remarkable improvement in runtime energy efficiency and executable code size.

ہجرت مدینہ

ہجرت مدینہ
ہجرت مدینہ سے قبل کئی مسلمان اذیتوں اور تکلیفوں کے سبب حبشہ ہجرت کر چکے تھے۔وہاں بھی قریش نے پل بھر سکھ کا سانس نہ لینے دیا۔اپنا وفد بھیج کر شاہ حبش سے درخواست کی کہ انھیں اپنے ملک سے نکال دیں۔شاہ حبش نے درخواست مسترد ہی نہیں کی بل کہ مسلمانوں سے کہا کہ میرے ملک میں جہاں چاہو رہو۔اب ایک اور مقام کی طرف مسلمان بہ حکم رسولﷺ مدینہ ہجرت کرنے لگے۔ایک ایک دو دو موقع پاکر جانے لگے۔دوسری طرف قریش کے ظلم و ستم کی وارداتیں بڑھتی گئیں۔ طرح طرح کی اذیتیں دیں۔یہاں تک کہ قریشی بی بی کا شوہر جو غیر کفو ہوتا اس کی ہجرت کرنے کا پتہ چلتا‘پکڑ لاتے اور ظلم ڈھاتے نیز حفظ ما تقدم کے تحت اس کی بیوی کو ضمانت کے طور پر نظر بند کر دیتے۔بعض شوہروں کو ہجرت سے روکتے‘ نہ رکتے تو قید کر دیتے۔ مسلمان بچارے پٹتے تھے لیکن آہ و زاری نہیں کرتے تھے تکلیفیں سہتے مگر حر ف شکا یت زبان پر نہیں لاتے تھے جو جو ظلم کر سکتے تھے قریش نے روا رکھا لیکن ظالم کو کیا خبر کہ مظلوموں پر کیسی قیامت گزر رہی ہے ۔ ہر طرف دکھوں اور دردوں کے پہرے تھے پھر بھی وہ صبر کا پہاڑ تھے ڈٹے رہے اور زبان شکر گزاری کے ترانے الاپتی تھی ۔ خد اکا نام لینا جرم تھا ، نماز یا تلاوت قرآن کر نا موت کو دعوت دینا تھی ۔ آفات و آلام ان کے تعاقب میں تھے اور بقول انوری جو بلا آسمان سے آتی ہے انوری کے گھر کا پتہ پوچھتی ہے گویا رات کی سنگینی کا عالم یہ تھا کہ خود حضور ﷺ ( جن کی حفاظت کا ذمہ خود خدا نے لیا تھا ، خطرے سے باہر نہ تھے ۔غرض ہر ظلم...

Effectiveness of Digital Health Services: Challenges and Constraints for Society

This article discusses the effectiveness of digital health services by looking at the challenges and obstacles for society. One form of public services implemented by the government for the community is meeting the need for quality public services and having an orientation to the effectiveness of services to the community that are needed. In the health sector itself, advances in information technology have greatly supported health services. This online system is of high quality to be implemented because the public and members of the medical system can receive and provide detailed and fast information with the help of computerized technology. Information technology has reached various fields of life including the health sector to help the efficiency and effectiveness of health services. Information technology that is properly implemented can support the management process to be effective and efficient. The corona pandemic is changing people's habits in visiting and consulting doctors at hospitals. However, digital-based health services have not been effectively accepted by the public from various service units. They still need improvements in terms of connectivity, content and clarity of regulations.

Learning Mathematical Rules With Reasoning

This research focused on students' learning of mathematical rules with reasoning. This includes studying the process of students' learning, how they make meanings of the mathematical rules they have learnt, how they relate, and the factors which enhance learning with reasoning. I worked with four students (grade six) with mixed ability from a private school. I engaged them in mathematical tasks for one hour outside of their classroom situation. Sessions were planned for twice a week for five weeks using the tasks designed on four basics rules of fractions, addition of fractions, subtraction of fractions, multiplication of fractions, and division of fractions. My role was dual in nature, that of a researcher as well as teacher. After determining the student’s prior knowledge of fractions in introductory sessions, I designed activities pertaining to the four rules of fractions. I used qualitative approaches for generating data. The main sources of data generation were field notes, audio tapes, observations, and students' work. My analysis started from the first day in form of analytical memos. I categorized themes through 'mapping method'. My biggest learning during this study was to learn about the factors which enhance students' leaning of mathematical rules with reasoning. This particular study provided me important insights, which influenced students learning. For example, role of teachers' questioning, role of concrete material and pictorial representations, role of conducive environment in the classroom and the role of students misconceptions and their prior knowledge. This study also discusses some of my learning as a teacher, teacher educator and as a researcher. On the basis of the findings the study makes significant recommendations to the community of teachers and teacher educators.
