Write 11 pages with APA style on Circuits with Feedback and Sine Wave Oscillators.

There are generally two types of feedback (Ashby, 2009). These are negative feedback and positive feedback. These two terminologies can be used in two different contexts. In the first context, the languages refer to the gap between the real parameter and the reference parameter. This is based upon whether such a gap widens. in this case, it is referred to as positive, or if the gap narrows, it is referred to as unfavourable. Whereas, in the second context, the effect or action is altering the gap basing on involvement in the non-reward (negative) and reward positively. According to Arkalgud (2005), positive feedback leads to an increase in the gain of an amplifier, while negative feedback causes a reduction in the amplifier’s gain.&nbsp.

However, these two contexts appear confusing. For instance, in the first case, different authors use various terms substituting negative/complimentary with self-correcting/self-reinforcing, balancing/reinforcing, degenerative/regenerative, and discrepancy-reducing/discrepancy-enhancing, among others (Arkalgud, 2005). Different authors describe the effect or action as a negative or positive reinforcement instead of feedback in the second case. However, this confusion comes about because feedback could be used for either motivational or informational reasons and contains both the quantitative and the qualitative components. Qualitative feedback explains how bad, right, or indifferent, whereas quantitative explains how many or otherwise. The negative and positive feedback reduces and increases the amplifier’s gain.

In negative feedback, the current or voltage feedback is applied to reduce the input amplifier. This is also called the inverse or degenerative feedback. In positive feedback, the current or voltage feedback is used to increase the voltage input. This is also referred to as direct or regenerative feedback (Stuart, 2007). On the other hand, negative feedback can be divided into voltage feedback and current feedback. In other cases, both feedbacks may exist in a circuit. In this case, both current voltages would be feedback towards the input in parallel or series. These cases would be represented as series-voltage feedback, series-current feedback, shunt current feedback, and shunt- voltage feedback (Arkalgud, 2005).

Write a 6 pages paper on electric and hybrid cars

The pressure from environmentalists and government regulations has seen car makers worldwide develop cunning technologies that aim to reduce the emission of carbon footprints from automobiles. Among them is the use of electric and hybrid car technologies (BRIAN, marshal, 2010).

How the technology works

So how do these technologies work?&nbsp. An electric car is a kind that does not burn any sort of fossil fuel to make it run like a conventional petrol or diesel-powered engines. Instead, the car gets its propulsion from an electric motor using energy stored in the cars’ batteries or hydrogen fuel cells. The vehicle can be powered by a variant number of electric motors ranging from one electric motor like that in a G-wiz to a staggering four like those in the new electric Mercedes SLS. The drive train of such cars usually is very light, while the gear system could encompass as little as one moving part (MODERN CARS, 2012). The cars’ weight is mostly contributed by the energy storage system, which in most cases can weigh as much as more than half the weight of the entire vehicle. The great idea behind this technology is that users would be able to plug in their cars to an electric outlet like the power grid and charge up their vehicles’ batteries. Once they are fully charged, they can drive for miles without any carbon emissions from the car. Surprisingly this technology was invented as early as the 1880s, but it was surpassed by the internal combustion engines (DAVIS, matt, 2011).

Challenges

However, I think it is fair to mention that electric cars have several challenges that have made them gain such low acceptance in the market chief, which is the mileage that can be achieved from a single full charge. Investors are always trying to figure out how they can have better batteries that can store electric voltages to increase their mileage. Tesla Motors in the United States of America seems to be at the forefront of this technology since they recently launched a range of car batteries used in their cars to achieve top mileage per charge. Electric vehicles can only achieve their sole purpose of being environmentally friendly by tapping into clean electricity sources like wind power and solar, but not that generated due to fossil fuels’ burning.

write an article on The Unending War in Iraq. It needs to be at least 1750 words.

This is due to the reason that, they termed the strategic actions by the USA as uncalled for. As such, there have been actions to seek a solution that would help to normalize such actions by the USA – that is, an independent body that would be in the position to either approve or disapprove the actions that the military takes. When compared to the UK newspapers, most of them did not give a sequence of the events as outlined in The Washington Post (2003). The closest elaboration was given by The Independent UK (2013) when the mentioned that the year 2013 was the 10th anniversary of the war in Iraq. In addition to that, instead of giving a description about the events that occurred in the 10-year crisis, they spoke more about Tony Blair, his decisions to take Britain to the war in Iraq, his opinions of the war and so on. Based on that, it can be concluded that The Washington Post (2003) was more elaborative with regard to the timeline of the war (the timeline of the war was significant to the US citizens) as compared to the UK newspaper which was more of a debate seeking to answer the question “Why Britain was involved in the war”. With regard to what The Independent UK (2013) discussed, it can be stated that the war in Iraq was not much of their concern. As such, it was close to not being significant to the British citizens.

As described by The Guardian UK (2004), the legality in the ideology that the USA conducted a legal invasion into Iraq is still a debate that has never had a sound solution. Nations such as UK and USA have long since been debating as to whether the war that sparked after the US took the step to invade Iraq will ever come to an end. As noted by the previous UN Secretary-General – Kofi Annan, the war in Iraq was very much illegal. In his statement, he mentioned that “from our point of view and the UN Charter point&nbsp.of view, it [the war] was illegal. In addition to that, Kofi Annan added that the USA would have taken the step to inform the Security Council about their decision rather than making a unilateral decision and acting on it without any discussion with the bodies responsible (The Guardian, 2004).&nbsp.

ompose a 2750 words assignment on the distribution board provided.

A distribution board is defined as “a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit, in a common enclosure.”

&nbsp.

DEFINITION OF EQUIPMENT AND PARTS.

Feeder:&nbsp. conductors that connect the power supply source and a final branch circuit over-current device.

N/C and N/O: these are the normally closed and normally open contacts respectively.

Normally closed (N/C) contact is one which is in conducting state when it or the device operating it is in a de-energized condition.

Normally open (N/O) contact is always non-conducting when it or the device operating. it is in a de-energized state. These two connect or disconnect the line from the load.

&nbsp.

Metering circuit breaker:

The American National Standards Institute (ANSI) defines a circuit breaker as: “A mechanical switching device, capable of making, carrying and breaking currents under normal circuit conditions. Also capable of making and carrying for a specified time and breaking currents under specified abnormal circuit conditions, such as those of a short circuit.”

The metering circuit breaker here protects the meter circuit from faults that could cause adverse effects on them. It operates by switching itself off in case of a spot. When the fault is rectified, it is switched on.

Remote emergency trip push button:

It is a switch usually located at a safer location and in this case, is used to shut down the power to the metering on emergency.

&nbsp.

22kV/110V VT’S – Metering Voltage Transformer:

It is a transformer used to monitor the power line voltage. This steps down line power from 22kV to 110V that can be applied to the measuring instruments without damaging them.

&nbsp.

400/5A, 100/5A CT’S – Metering Current Transformer:

It is a transformer used to monitor the power line current. It isolates the meters from the broad wind of the line and provides a reduced current that can be consumed by the measuring instrument.

The 400/5A reduces current from 400 amperes to 5 amperes suitable for metering instruments.

&nbsp.Likewise, 100A/5A steps down current from 100A to 5A to be used in metering.

&nbsp.

TX2 1000kVA 10,000/400V Transformer:

A step-down Delta/Wye transformer that converts 10kV to 400V for low voltage consumption. It has a rating of 1000kVA. The delta/wye configuration is the most commonly used in 3-phase transformers because the wye on the secondary side gives a fourth conductor, the neutral, which is useful in LV distribution. It facilitates the use of single-phase power from a 3-phase LV line.

Main Incomer:

Found on the main distribution board and it acts like a switch which is responsible for switching the phases and neutrals for the whole power supply.

6 Stage 200kVAr PFC Unit with Auto Control:

This is a power factor correction (PFC) unit with a 200kVAr rating. The control parameter is VAR and not PF (power factor). Target PF value is just used to calculate the capacitive VAR required to be added/removed to achieve the desired.

write an article on Freedom of Speech within Utilitarian Approach. It needs to be at least 1500 words.

According to the majority of the philosophers, the general notion of belief is that there is compatibility between utilitarianism and moral rights. For instance, the famous British philosopher John Stuart Mill, whose contribution is immense in the field of philosophy, perceives a congruency between utilitarianism and moral rights. The constitutional right to freedom of speech enables an individual to protect his freedom of expression (Wellman 2005, p.145). Philosopher Mill loyally supported utilitarianism, and at the same time, defended freedom of speech until or unless it torments the sentiments of others. However, some philosophers believe that there is an incongruous relation between utilitarianism and moral rights (Brandt 1984, p.1).

To understand the interaction between utilitarianism and moral rights, it is necessary to define utilitarianism at first. According to John Stuart Mill, “the utilitarian approach is that happiness is desirable, and the only thing, desirable as an end. all other things being desirable as means to that end.” In support of this, he has also mentioned: “If so, happiness is the sole end of human action, and the promotion of it is the test by which to judge of all human conduct, from whence it necessarily follows that it must be the criterion of morality since a part is included in the whole” (Brandt 1992, pp.197-198). The concept of utilitarianism was ushered in the 19th century by Jeremy Bentham and John Stuart Mill to help the legislative units frame different laws that are morally optimal. In the utilitarian approach, firstly, various courses of action are identified. After that, the entities to be possibly affected by each action and what benefits or harms will be caused by each action need to be evaluated. Lastly, a certain action is chosen to produce&nbsp.the greatest benefits and least harm (Velasquez et al., 2010).

Freedom of speech is invariably represented as a fundamental right by the written Constitution and bills against state suppression and regulation. Freedom of speech is an important concept. The prime function of freedom of speech is a representative range of views. These views are mainly responsible for the decision-making processes at all levels in a societal structure.

Create a 5 pages page paper that discusses the impacts of trauma in stressful life behaviors.

For instant when one has received urgent `appalling information, concerning the death of the most loved ones in the family, the victim will be traumatized, for example, one receiving the news about the death of the mother, or father who are close family members.

Trauma might have a very negative effect on our minds and bodies, when one perceives a threat, the body will activate the stress response hormone. The response occurs in both the body and mind. It’s for an emergency, adrenaline together with other hormones is released. The body will shut down the process connected with such long-term care. When the body is under immediate danger, the reproduction, digestion, cell repairs, and the body task related to long term functioning become unimportant. The immediate vital is the survival of the victim. the increased blood sugar provides more energy for the muscle (Van, 43).

Individuals undergoing trauma, may longer-term reactions that include unforeseen, emotional flashbacks, nervous relationships, or even physical symptoms such as nausea or headache. The feelings of trauma are normal, but some people may have difficulties moving on with their normal daily life provision. Through the attendance to the psychologist’s trauma, provision is treated, by looking for constructive ways for such an individual’s effectiveness in managing their emotions. If individuals suffering from trauma are not taken care of, their situation becomes more worsen hence can die.

Disasters like earthquakes, hurricanes transportation accidents, hurricanes or wildfires are classically unanticipated, impulsive, and overpowering. There are no superficially visible signs of physical wound, but an emotional toll. Following such a situation, one may feel bewildered, disoriented, or unable to integrated upsetting information (Van, 43). Once these preliminary reactions subside, individuals may experience a variety of behaviors and thoughts. The common responses may be, changes to thoughts and the behavior patterns individuals might experience repeated and the glowing memories of that event.

submit a 1500 words paper on the topic Procurement and Contracting in the Repair of Uxbridge Water PLCs Flood Relief Sewer.

. Uxbridge Water PLC, hereafter referred to as UW, is a public company. hence, it is obligated to follow government-approved procurement and contracting procedures. There are a number of factors that need to be considered in this case.

i. The sewer line runs directly under Brunel University’s main campus. Uxbridge Water PLC must, therefore, involve the university in the project. This will be necessary to ensure that the development does not obstruct the university’s undertakings. It will also help the firm to avoid any legal challenges. the university could sue the company for trespassing, environmental degradation, or noise pollution if it is not involved in the project.

The project will involve the procurement of construction material, equipment, and personnel. In addition, there may be other trivial resources required that will have to be obtained. The project has been pitted to cost £1 million. this is quite a large amount of public money. hence, it is crucial for UW to be able to account for every single cent of it.

There are a number of procurement strategies that UW could opt to use. This section of this document provides an assessment of these strategies, making recommendations on their suitability for the project.

If adopted, this model will have UW carry out all the necessary assessments and preparations for the project before inviting contractors to tender for it. This includes making designs of how the new lining will be implemented.

This procurement plan will give Uxbridge Water PLC control over vital aspects such as quality, costs, and specifications. This is brought about by the fact that the company will determine what the contractor does by coming up with the designs.

However, the strategy leaves all responsibility for risks at the hands of the client. hence, UW should be prepared to bear any discrepancies that arise due to its designs and specifications. Despite the various advantages, this method will present to Uxbridge Water PLC there is some uncertainty over its implementation. the contractor is not consulted during the design process and yet their input is extremely critical to the success of such projects.
