Dynamic voltage scaling

Two computation cases were introduced, one with a polyurethane graft and another with a silicon rubber graft. The computations were done under a pulsatile flow. Both cases were computed under maximum peak pressure as mentioned in the method section. The flow volume rate is expressed by integrating on surface as followed: Q=∬_A^ ▒v.dA (5) By integrating flow volume rate in time…

Name Wave An icebreaker is a facilitation exercise intended to help a group begin the process of forming themselves into a team (Furman, Bender, & Rowan, 2014). Name Wave is an impromptu icebreaker game that helps the group leader and participants learn their fellow members’ names and may also provide hints about their personality traits. Description of Activity The group forms a circle and then the leader of the group introduces him or herself, saying their name and doing an action (anything…

Thermal dispersion mass flow meters, often called thermal mass flow meters, rely on the transmission of heat from a body to a gas flow. Inside the flow meter sensor head, a heated resistance thermometer (RTD) is electronically compared with an unheated RTD sensor. As a gas passes the heated RTD, heat is transferred from this sensor to the gas, and hence the RTD is cooled, thereby reducing the temperature difference between the two sensors. Heat transfer from the RTD to the process gas is based…

2.3 Computational fluid dynamics Computational fluid dynamics or commonly abbreviated as CFD is the branch of fluid dynamics which is applied to simulate fluid flow, heat transfer, and associated phenomena such as chemical reactions by the numerical solution of the governing equations to analyze complex flows system such as complex turbulent flow (Versteeg and Malalasekera, 1995). Therefore, CFD has often been provided as the tool for testing of conditions which are not possible or difficult…

Once the members are able to settle in and their inclusion needs are fulfilled, members will move to the next phase which is the control phase. Members are now concern on whether they are in a top or down position in the group. Some control issues might arises such as their ability to influence other members and their particular responsibility in the group. Members are curious about the rules and regulations of the group, roles of the leaders and each member as well as other issues related to…

Chapter 1 Introduction 1.1 What is aerofoil? Aerofoil is a large stucture which is attached to the airplane. It has curved surfaces designed to give required ratio of lift and drag. It helps to create different aeodynamic forces. The force perpendicular to the motion of aeofoil is lift force. The force parallel to the motion of aerofoil is drag force. 1.2 How it works? Aerofoil consists of following components: • Suction surface • Pressure surface • Leading edge • Tailing edge •…

5. 3. 4 Typical application and thermometric error Consider a typical application such as the measurement of surface temperature by a surface mounted thermocouple as shown in Figure 5.9 (a). Figure 5. 9 : (a) Surface mounted thermocouple in Example 5. 1 (b) Thermal resistance network model Heat loss from the thermocouple is modeled as shown above by discussion leading to Equation 5.3. Thermocouple attached to the surface of a massive solid whose temperature we would like to measure.…

INTRODUCTION Group is a collection of people who share definable membership, group consciousness, a sense of shared purpose, interdependence and interaction. (Mullins, 2005) According to Robin and Judge (2013), defined group as two or more individual interacting and interdependent who have come together to achieve a common set of goals. Mullins (2013), explains two types of groups which are formal and informal groups. Formal groups are deliberately planned and created by management as part of…

Vertical dimension (VD) defined in the Glossary of Prosthodontic Terms as "The distance between two selected anatomic or marked points”. Occlusal vertical dimension (OVD) defined as "The distance between two selected anatomic points when in maximal inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of…

Table 2.1: Parameters of tested water turbines (by Shionoet.al, 2002) Solidity (σ) Chord length (C) (mm) Blade inclination angle(ɸ)(°) Height (h) (mm) 0.20 62.8 43.7 300 0.30 94.2 43.7 300 0.40 125.7 43.7 300 0.50 157.1 43.7 300 0.40 125.7 50.0 374 0.40 125.7 60.0 544 Next, the effect of solidity σ on the water turbine characteristics was measured. Figure 2.1 shows a comparative analysis of torque characteristics for different solidity ratios at velocity 1.0 m/s, performed by Shionoet.…
