Collision-Free MAC Protocol for Wireless Sensor Networks Muneeb Ali‚ Tashfeen Suleman‚ and Zartash Afzal Uzmi Computer Science Department‚ LUMS {muneeb‚tashfeens‚zartash}@lums.edu.pk Abstract Mobility in wireless sensor networks poses unique challenges to the medium access control (MAC) protocol design. Previous MAC protocols for sensor networks assume static sensor nodes and focus on energyefficiency. In this paper‚ we present a mobilityadaptive‚ collision-free medium access control protocol (MMAC) for

Interview protocol Primary Questions (Please think carefully about these prior to the interview) 1. When you think about your career as a manager‚ certain events or episodes stand out in your mind—things that changed you in some way and have ultimately shaped you as an executive. Please choose three of these experiences that have had a lasting impact on you as a manager or executive in international work. When I meet with you‚ I will ask you about each of these “key events” in your career: what

This presentation was informational about SIOP. I learned that SIOP stands for Sheltered Instruction Observation Protocol Model. Sarah Eakin stated‚ “SIOP is a research-based and validated instructional model that has proven effective in addressing the academic needs of English learned throughout the United States.” SIOP consists of eight components: lesson preparation‚ building background‚ comprehensible input‚ strategies‚ interaction‚ practice/application‚ lesson delivery‚ review and assessment

studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure of the

Lab #6: pH Effects and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction
