Water And Minerals Presentation Transcript:1.Water And Minerals
2.Calcium and PhosphorusUsed to build bones and teeth.99% of total body calcium is found in bones and teeth.Calcium and Phosphate crystals bond together to form HYDROXYAPATITE.
3.Hydroxyapatite is what gives bones strength.Bones are being rebuilt each day, therefore the calcium in the bones is constantly changing.Now calcium in teeth has a similar role.However the mineral turnover is not as rapid as that in bones
4.Calcium also circulates in the bloodThere is a constant level maintained so that it is always available when needed.Helps: muscles contract, nerves transmit impulses and blood to clotCan also help lower blood pressure
5.Phosphorus also circulates in the bloodInvolved in metabolismPart of DNA and needed to growBuffers both acids and bases in all the body’s cells.Milk and milk products are excellent sources of calcium and phosphorus.
6.MagnesiumFound in all body tissues60% of it is found in bonesThe other 40% is distributed between the soft tissues such as muscles and blood.The body works hard to keep blood levels of magnesium constant.
7.Magnesium is essential for systems responsible for energy metabolism.Building bones and maintaining teethMuscle relaxation and nerve transmission.Keeps the immune system working.
8.These are some of the different foods that contain magnesium.Buckwheat Flour and Bulghur, dry contain the highest amount of magnesium in this
9.SodiumPart of the electrolytes group(sodium, potassium, &chloride) Sodium is a positively charged ion that is found mostly in the fluid outside the cells.The major source of sodium in the diet is saltMany processed foods are high in sodiumHigh Blood pressure also known as hypertension is the most important health issue caused by overconsumption of sodiumDo not consume more than 1500mg per day
10.PotassiumAlso an electrolyteFound in the fluid inside individual body cellsHelps maintain water balance and acid base balanceHelps muscles contractHelps maintain a healthy heartbeatHelps send nerve impulses.
11.ChlorideAlso an electrolyteHelps maintain water balance and acid base balancePart of hydrochloric acid which is highly concentrated in stomach juices.Aids in protein digestion, destroys harmful bacteria, and increases the absorption of calcium and iron.
12.IronOne of the most abundant metalsMost important in the bodyKey component of hemoglobinAlso part of myoglobin Works with enzymes in energy metabolismNecessary for the body to produce energy
13.15% of the body’s iron is stored in the bone marrow, spleen and liver for future useMeat, Poultry, and Fish are great sources of iron
14.15% of the body’s iron is stored in the bone marrow, spleen and liver for future useMeat, Poultry, and Fish are great sources of iron

TRANSISTOR AGING Presentation Transcript:1.TRANSISTOR AGING
2.INTRODUCTIONTransistors do age ….like Humans!!Time by time degradation of performance of a transistor is called Transistor Aging.The degradation of transistors occurs over time and can result in circuit failure!!!Several different phenomena can degrade the transistors.
3.WHAT WE ALREADY KNOWA transistor is a three terminal semiconductor device used to amplify and switch electronic signals.It is the fundamental building block of modern electronic devices.ADVANTAGES: Smaller, less expensive, requires less electricity etc.APPLICATIONS: Hearing aids,Watches,Cameras, TV etc.
4.AGING MECHANISMSOXIDE BREAKDOWN.HOT CARRIER INJECTION.NEGATIVE BIAS TEMPERATURE INSTABILITY(NBTI).
5.OXIDE BREAKDOWN:Refers to the destruction of an oxide layer. Defects within the gate oxide are usually called traps.They are called traps because the degraded Oxide can trap charges. Traps are usually neutral. Once these traps form a conduction path from the gate to the channel, breakdown occurs.
6.NEGATIVE BIAS TEMPERATURE INSTABILITY(NBTI): Occur due to the application of negative bias to gate at elevated temperature.Traps charge within the dielectric.Whenever you apply gate voltage, charge buildup in the dielectric.
7.HOT CARRIER INJECTION: A carrier is injected from the conducting channel in the silicon substrate to the SiO2 layer. Since the charge carriers becomes trapped in the SiO2 layer of a MOS transistor, the voltage needed to turn on the transistor increases .As a result transistor switches more and more slowly.
8.OXIDE BREAKDOWNGate-oxide breakdown begins when traps form in the gate-oxide.more and more traps are created in the gate-oxide.traps start to overlap creating a conduction path-breakdown occurs-SOFT BREAKDOWN(SBD).Once there is conduction, new traps are created by thermal damage, which in turn allows for increased conductance.
9.This cycle of conduction leading to increased heat leads to thermal runaway.The Silicon within the breakdown spot starts to melt, and Oxygen is releasedSilicon filament is formed in the breakdown spot.
10.CROSS SECTION OF GATE OXIDE AFTER HARD BREAKDOWN THROUGH EMISSION- MICROSCOPY.
11.TRAP GENERATIONThere are different theories on how defects are generated in the gate-oxide.The two main models are :The Thermo chemical model .The Anode Hole Injection (AHI)model.
12.AHI MODELThe AHI model is based on the process of electron injection into the oxide and holes are generated at the anode which then gets trapped into the oxide.At high electric fields, the electrons arriving at the gate have a high kinetic energy (> 8MV/cm).
13.When these hot electrons reach the gate electrode they transfer their entire energy to a deep-valence band electron, andthis electron is promoted to the lowest available electron energy state, which is the conduction band edge .Once the electron reaches the conduction band, it creates a hot hole, which tunnels into the oxide.
14.The holes which enter the oxide, allow for increased current density.Due to increased current density, more electrons tunnel in to the gate and more holes are created.These holes creates traps within the oxide.
15.How to limit degradation?Prevention cannot be done, as for most of the electronic devices, they will loose their properties over time.To limit transistor aging effect in a circuit, various method can be used.Lets discuss some of them.

CODE LOCK Presentation Transcript:1.INTRODUCTION Digital Code Lock using AT89C2051 is a basic control system with an ability that allows any user having valid user password or Master password to use the system with simple password protection This code can be changed by the user. This circuit is eminently suitable as a digital lock with security option. Digital code lock is a type of lock in which any combination of 5 digits is used to open the lock. This type of lock use numerical code for authentication where the correct code must be entered in order for the lock to deactivate. The lock can be used with an outdoor gate or a normal door. The functionality of this lock is implemented in software When the correct code is entered it will open the door. The significant of this project is to eliminate the need for a key.
2.NEED OF CODE LOCKThis kind of lock can avoiding the problems caused by the copying of keys. On the premise that it’s safety is high, it’s another feature without key is getting more and more favour of peopleThere are great varieties of digital code locks. Generally speaking, they can be classified into scores of type, such as electronic lock, fingerprint lock, card lock biological lock, etc.
3.OBJECTIVESTo free users from the worry of remembering keysTo design a keyless door entry by using electronic digital lock codeTo avoid any crimes especially stealing activities
4.WIRING CIRCUIT
5.ADVANTAGESWHEN SYSTEM IS BLOCKED AFTER UNSUCCESFUL ATTEMPTS THEN JUST ENTER THE MASTERCODE ,THE SYSTEM WILL BE UNBLOCKED.SO THERE IS NO NEED TO ‘POWER OFF’ THE SYSTEM FOR RESETTING.THERE IS NO NEED TO ENTER THE SECURITY CODE TO LOCK THE SYSTEM AGAIN, JUST PRESS THE ‘#’ KEY TO LOCK AGAIN.EVERYTIME THE SECURITY CODE CHANGES IT IS NOT SAME FOR ALL THE CASES , AND THE PERSON WHO KNOW ABOUT THE SYSTEM THOROUGHLY ONLY HE CAN CHANGE THE CODE.SO THIS THING PREVENTS THE SYSTEM FROM HACKING.
6.This digital code lock is therefore particularly useful in applications such as hotel room door locks, residential housing and even office buildings.We feel that this digital code lock is very marketable because it is easy to use, comparatively inexpensive due to low power consumption and highly reliableLock which contained hardware and software development. We also know and understand the microcontroller AT89C2051 and how to implement it on my project

DMAIC Presentation Transcript:1.Executive SummaryDefine PhaseD1. Project CharterD2. Customer RequirementsD3. High-level process mapMeasure phaseAnalyze PhaseImprove PhaseControl phaseToolsWorks Cited
2.Executive Summary The IT industry is one of the fastest growing industries in the world today. The industry is populous with IT service companies, one of the services offered is customer care support services either online or via telephone calls. The high competition leads to lowered prices that often they equally range across all the companies in a given market. For a company to remain in the market and profitably run its activities as usual, it has to offer the best services than its competitors. This case study applies the Six Sigma techniques like DMAIC .Benchmarking and just setting a project team to work on the basis on a simple six sigma may not fully solve a problem. DMAIC defines the issues affecting the company to a large span making it easier to distill more clues and real figures from the top performers in the industry thus acquiring facts and reliable data to promote the project.If data from an unbiased source is used, say the company studied has customer care satisfaction ratings of seventy-three out of a hundred; the ‘average’ company in the industry has a rating of seventy-six out of a hundred and the best performer in the industry at eighty seven percent. This data alone shows that efforts have to be made in order for the company to survive the competition. In the IT service industry customer satisfaction is a major contributor to a company’s growth (Hallowell).Support costs per call are not related to satisfaction, best companies’ support call cost $26, ‘average’ companies at $30 per call while the case study company’ call cost about $36 which is the highest of all (Hallowell).On focusing the DMAIC project the ‘Y’ being new account growth and the ‘Xs’ being number of transfers, wait time and service. Wait time is associated with customer satisfaction thus improvement on the time is essential. After discovery of the points of weakness: the company managers then set project goals, scope and the study case using DMAIC (Define, Measure, Analyze, Improve, Control) teams.
3.D1. Project Charter: It expands on the business case clarifying the focus, measures of the project’s performance, and completed by a six sigma Black Belts who are the team leaders. They respond by implementing the improvement projects using skills of six sigma tools and lead increase of customer satisfaction. The key stakeholders are the customers, staff members and the business. The problem statement is one of the project charter elements; it gives the progress of the competitors as compared to the stagnated case study company. Goal statement element is that the customer satisfaction rating is at 90th percentile=75% targeting 85% in the same percentile by end of fourth quarter without changing support costs. The last element is process output such as milestones, roles, communication procedure (Hallowell)
4.Continuation of define phaseD2. Customer Requirements: using SIPOC (Suppliers, Inputs, processes, outputs and customers) identify the important customers for instance, customers, staff and business. Voice –of –customer inter views can be used to know what influences their level of satisfaction with the services offered. A summary outcome of the customer requirements is as follows;
5.Measure phaseDefine how data is to be gathered. For example; satisfaction-by standard survey per month in the industry, one by one customer satisfaction data.Performance standards; satisfaction- 90th percentile (70-80%) satisfied, performance -90th percentile (85% satisfied)Factors for data acquisition plan; collection efforts, cause-and-effect tools in use, nature of segmentation of Y-call center and product, factors driving Ys- the important X (call type or customer type).Measurement system; its accuracy, stability over time, repeatability of the same value, reproducibility when used by different people. Collection of data can be automated, manual and by use of any other metrics. Display data in a simple format to enable the team to look for clues in charts and graphs (Hallowell).
6.Analyze PhaseAnalysis is performed to check the capability of the process as compared to the present standards. Adjustment is done if the goal is not meeting the expectations. Data is partitioned in order to find the causes of the variations. Identify the possible X and verify to narrow down to see the important causes of variation. Update the prediction on how improvement can be achieves in the process. It can be found that satisfaction and support costs are affected by wait time and interruptions during call service.
7.Continuation of Analyze phaseA1: Define Performance of the process Measurement of the current process capabilities to enable proper definition of the projects’ objectives. Here the root causes and drivers of the problems are critically analyzed.
A2: Suggest the improvement Objectives If the analysis in A1 shows that the is variation from the expected results then proper measures should be taken to improve the outcome of the overall process.
8.Identify Value/Non-Value Added Process Steps
By dividing the Y values based on the main factors (X's) as identified during the Measure phase – the team looks for patterns that shed light on what may be causing or driving the observed Y variations.
9.Determine Root Cause(s)Collecting the findings that came out of A3, the team posed strongest in the form of "why" questions:Why do transfer rates differ by call type? (higher on Problems and Changes, lower on others)Why do Problems and Changes cost more than other call types? Why are calls processed on Mondays and Fridays more expensive? Why are wait times higher on Mondays and Fridays and on Week 13 of each quarter?
10.Determine Vital Few X's, Y=f(x) Relationship This is achieved when the main causes are sorted from the least effective drivers . This enable graphical data to be converted to statistical data that is easier to calculate the general outcome.
11.Improve PhaseHere are some of the solutions that can be made within the processes to improve growth of the case study company.Staffing; More staff on weekdays and reduce their number in the weekends especially on Sundays. Use of web service; services that can be done best online should be done on the web, it reaches many people over a limited time and give incentives to gain web traffic.Transfers and callbacks; reduce them by improving the processes using newer technologies. Improvement can be achieved by verifying relationships between Xs and Ys by use of solution selection matrix and regression analysis
12.Control phaseControl plans should be done by use of dashboards-Ys and operational control indicators. Improved capabilities of the process should be determined using the following factors. Business growthSatisfactionReduced wait timeTransfers and service timeLess support cost per call. Continuous data collection should be implemented. Closing the project is done and training starts for project post mortem.Tools Used; ANOVA, Cause and Effect Diagram, Control chart, Kano Analysis, X-Bar and R Charts
