Why do I want to add a pole to a closed loop transfer function. Keep your answer short. What are the types of stabilities? What type of system is marginally unstable. Solution Problem 3 Effect of adding pole to closed loop transfer function The addition of left half pole tends to slow down the system response. The effect of addition of pole becomes more pronounced as pole location drifts away from imaginary axis. Addition of right half pole will make overall system response to be an unstable one. Problem 4 Different kinds os stabilities are :BIBO Stable, Marginally Stable, Conditionally Stable, Uniformly Stable, Asymptoticly Stable Problem 5 When the poles of the system in the complex S-Domain exist on the complex frequency axis (the vertical axis) ,the system exhibits oscillatory characteristics, and is said to be marginally stable. A marginally stable system may become unstable under certain circumstances, and may be perfectly stable under other circumstances. It is impossible to tell by inspection whether a marginally stable system will become unstable or not..

Why is Inflow and Infiltration (I/I) an issue for wastewater treatment plants? Explain in terms of what causes it, the sources of I/I, and its impact on hydraulic capacity and treatment efficiencies at wastewater treatment plant? Solution Infiltration is due to the excess water that sometimes seeps, trickles, or flows into old or damaged collection systems from the surrounding soil. Inflow is due to additional unwanted water that enter collection systems from above ground sources. For example , due to excess rainfall, from private properties Causes: a) Infiltration: 1. poor soil conditions in which sewer lines are laid 2.poor construction materials or shoddy construction and workmanship b) Inflow 1.Poor planing of the sewerage system 2.draining of swamps, wetlands, or low-lying or flooded areas into collection systems through connect i o n s or leaky manhole covers. Effect on plant 1. Due to Inflow and infiltraion, there exists a uncertainity of amount of water is about to enter the waste water plant. Greater than anticipated flow comes to plant 2. As we know waste water treatemnt plant depends on microbial activity, change in loading rate causes death of microorganisms. 3.Increases treatment cost 4.Decrease in efficiency of plant.

Why is concrete such a widely used construction material? Concrete is basically, (fine and coarse), abd paste\" (water and Portland cement) The devolvement of cementing materials traces back to the Egyptians and Romans. In 1824, Joseph Aspdin produced a Portland cement from a heated mixture of and .in 1872 the first Portland cement plant was opened in. A material that reacts with water to form a hardened mass. The chemical reaction between water and Portland cement, that leads to the formation of hardened concrete. A by-product of the hydration reaction between water and Portland cement. The leaching of free lime. Caused by a reaction of chemicals in the mix water with the cement paste, usually leaving a white stain Solution portland cement is from a heated mixture of clay and calcium carbonate cement: it is the material which reacts with water and forms a hardend mass hydration of cement : the chemical reaction between water and cement , that leads to the formation of hardend mass tricalcium silicate C3S : it is the by product of hydration reaction between water and cement compaction of concrete : it increases the density of plastic concrete by expelleing the entraped air water cement ratio : the ratio of mass of water to that of cement in batch of plastic concrete admixtures : any ingredient other than cement , water, or aggregates , that is added to a batch of plastic concrete to impart certain desirable properties to the plastic or hardened concrete flashing: the ability of cemtn to maintain a stable volume after setting.

Why do the mean, median, and mode coincide at 0 on the normal curve Solution The shape of the normal curve is bell shaped (graphically ) The curve has a single peak thus it is unimodel. The mean of a normally distributed population lies at the centre of its curve. Because of the symmetry, the median (Positional average) a mode (concentration of frequency) also lies at the centre. Thus in normal distribution mean, median and mode all coincide at zero..

What is the role of a jury in a criminal case? Is it important or unnecessary ? Can I get a thesis statement for this ? What is the role of a jury in a criminal case? Is it important or unnecessary ? Can I get a thesis statement for this ? Solution ROLE of JURY Juries are seen as playing an important role in our legal system. Juries have been used as part of our legal system for more than one thousand years but it was not until trial by ordeal was done away with in 1215 that they became an integral part of our criminal justice system. In the same yearMagna Carta also formally acknowledged the principle of an individual’s right to trial by their peers. The jury we are now familiar with and whose role it is to “faithfully try the defendant and give a true verdict according to the evidence” is relatively young. It is only over the last 300 years or so that a jury has become established which is as independent as we now see it and which does not have any influence on law making or any knowledge of the defendant. Set out below is the role of juries in criminal cases. Juries are used in trials in the Crown Court. The jurisdiction of the Crown Court provides for the hearing of more serious offences on indictment. The offenders will have first appeared in the Magistrates’ Court and been committed or indicted to trial at the Crown Court. If there is a not guilty plea there will be a jury trial. If a guilty plea is entered then there will be no need for a trial and the Judge will decide upon the appropriate sentence. The jury is randomly selected from persons entered on the electoral register and they must not be involved in any way with the case. They are required to make an informed decision about whether the accused is guilty or innocent. The jury is told by the trial judge that they must base their decision upon the evidence put before them during the trial and not upon anything else, including things said outside of the court or anything they may have read. The jury must therefore listen to the evidence but their role may also include being made aware of physical exhibits and photographs and in some complex cases may include accompanied visits to crime scenes. Towards the end of the trial, and once all the evidence has been presented by both sides, it is the job of the trial judge to assist the jury in their task by summing up the evidence and directing them as to what the law is. After the summing up, the jury are put in the hands of a jury bailiff who is sworn in and made aware of their duties by the trial judge. The jury leaves the court and must retire to a jury room where they are required to deliberate and come to a decision as to whether the defendant is guilty or not. The jury will deliberate in private. Despite any direction by the trial judge about the law and the facts of the case at the end of the trial, one feature of the jury system is that the jury are free to make up their own minds, free from any outside influence and pressure.

What is the reuse ratio? Propose a comprehensive communications infrastructure for a developing country. Justify your recommendations. Solution The proposed communications infrastructure for a developing country is wireless communications. Wireless communications works most efficiently when supported by satellite, infrared, microwave and radio communications and also it is cheap to install. Its most important advantage is its mobility. It has specific security system for protection. Wireless communications provide continuous contact with the provider through the SID (system identification code) via the cell base station (BS). The capacity of wireless communication system can be increased by adding complexity and relaxing the channel allocation rules like Cell splitting, Allocation of new channels, Frequency borrowing and Alternative multiple access architectures..

Which salt is more soluble in water: CaCO_3 vs. MgCO_3 ? What are two major problems associated with hard water? List two technologies for water softening. What is the pH range of most natural waters? Name three weak bases found in natural waters. River A with a flow rate of 16,000 m^3/d flows into a well-mixed lake with a volume of 1,000,000 m^3 throughout the year. River B and river C leave the lake. A boat in the lake has polluted the lake with an organic pollutant. Microbes present in the lake are capable of biodegrading this pollutant with a first- order decay constant of 0.01 d^-1. Determine the percent removal of pollutant in river C (or the percent decrease of the pollutant concentration in river C) after 180 days. The mineral analysis in mg/L as ion for a water source is: Ca^2+ 100 Mg^2+ 20 HCO_3^- 200 CO_2 20 How much lime and soda are required (in mg/L as CaCO_3) to soften the water to 100 mg/L as CaCO_3? A water sample contains 20 mg/L of sodium hydroxide. How much manganese (II) is soluble in this water? Determine the percent dissociation of bicarbonate in this water. Solution 1. (a) MgCo3 is more soluble in water than CaCo3. (b). Problems associated with hard water: Laundering: Clothes washed in hard water often look dingy and feel harsh and scratchy. The hardness minerals combine with some soils to form insoluble salts, making them difficult to remove. Soil on clothes can introduce even more hardness minerals into the wash water. Continuous laundering in hard water can damage fibers and shorten the life of clothes by up to 40 percent. Bathing: Bathing with soap in hard water leaves a film of sticky soap curd on the skin. The film may prevent removal of soil and bacteria. Soap curd interferes with the return of skin to its normal, slightly acid condition, and may lead to irritation. Soap curd on hair may make it dull, lifeless and difficult to manage. Dishwashers: When washing dishes, especially in a dishwasher, hard water may cause spotting and filming on your crockery. The minerals from hard water are released faster when it comes into contact with heat, causing an increase in the amount of spotting and filming that occurs. This problem is not a health risk, but it can be a nuisance to clean and reduce the quality of your crockery. (c) (i) Ion Exchange : The oldest method of treating hard water, ion exchange uses a process of removing calcium and magnesium from the water by exchanging each calcium ion for two sodium ions. (ii) Distillation: Distillation is a water purification process that uses a heat source to turn the water into its gaseous form and thereby separate it from contaminants and other undesirable elements commonly found in ground and surface water. Distillation heats raw (untreated) water until the water reaches its boiling point and begins to turn into a gas. (iii) Membrane Technology: Membrane technologies like RO (reverse osmosis) push water through a semi-permeable membrane to filter out nearly all dissolved .
