Some universities now offer their courses on the Internet so that people can study online. Is this a positive or negative development? Nowadays, with technological improvements, specifically the Internet bandwidth, and growing websites and platforms, online education has become a hot trend. It seems that some universities tend to embrace this new occasion to develop their education system. Although, likewise other issues, online training includes various advantages and disadvantages, I tend to declare that this opportunity have has/offers numerous benefits for society and should not be ignored easily. Online courses can be divided in two parts, holding an online class and publishing a video of a course on the internet. In regard to online classes, time-saving is a noticeable item which is obvious to point out. Spent spending a lot of the time to traveling a long distance from house to university, students can replace it with other efficient activities, such as reading a book, reviewing lessons, doing homework, and you name it. Flexibility in both time and place is another factor that contributes to time-saving which is more obvious in online courses. In other words, people can easily reschedule their program not to not spend their time efficiently regardless of their location. Take the example that someone who is at work can take an online course during their rest time. Moreover, the a more larger number of people can apply for a course in this type of education. On the other hand, due to the novelty of this studying approach, there are negative spots which should be alleviated as soon as possible. From a psychological point of view, lack of communication between classmates and also between teachers and students, reduction of motivation and concentrations of students to effectively take a course or attend an online class, can result in a decrease of/in the quality of education. To mention the other pitfalls of offering online courses, requiring modern devices such as a laptop and having a reliable connection is crucial which are not available for everyone. To sum up, from my point of view, despite the drawbacks of publishing the courses on the internet, it is a wise decision that is made by several universities that to promoting promote online education whosethat its benefits outweigh the disadvantages by far.

Using animals to test the safety of cosmetics or drugs used for medical reasons is never acceptable. To what extent do you agree with this statement? I am absolutely positive that this is nothing save lack of compassion. Nowadays with so many advances facing us in almost every field including medicine and the cosmetic industry, there is a heated debate as to whether moral standards are properly observed or not. By the same token, there are questions as to what institutions are liable for setting and enforce enforcing regulations on animal experiments. My firm conviction is that some of these clinical trials are nothing short of inhumanity and ruthlessness, hence the significance of seeking alternative option. With respect to the advocates of animal research, they arguably draw attention to this disputable fact that human health and lives supersede than those of animals. For this reason, they justify conducting investigation on laboratory animals. Having said that, it ignores the fact that whereas it takes a plethora of energy and time to discover alternatives, it might be well worth the effort in the future not only for animals, but also for humankind at large. Regarding to the alternative option, I would like to point out to in vitro experiments as opposed to in vivo ones, by which I mean studies that are carried out in the laboratory and outside of the animals’ bodies. To bring this topic to light we need to get acquainted with a discipline namely tissue engineering. In this field of study artificial tissues are made in the laboratory which are similar to those of the human body’s tissues to a great extent. For instance, cosmetic companies are able to test their products on artificial pieces of skin. Likewise, pharmaceuticalcompanies could examine the active ingredient of drugs on special synthetic tissues. To summarize, I strongly believe that since the ultimate responsibility to safeguard the environment and its creatures lies with the public either directly or through its government, we should enact some new legislation on animal experiments and spare no effort to minimize animal studies irrespective of however difficult it is.

Some people think that the best way to increase road safety is to increase the minimum legal age for driving cars or riding motorbikes. To what extant do you agree or disagree? Some individuals believe that rising the minimum legal age for driving cars and motorbikes is the most effective solution of increasing the road safety. I some how agree with this opinion but I believe there are other solutions for this issue. It might be a beneficial idea to increase the minimum age for driving because of some reason. Firstly, younger people are usually less responsible with their manners and they are more careless about following rules and do not following rules is one of the main reason of accident and they are less mature to understand what the consequences of accident are. Secondly, older people can control the cars or motorbikes better because of their experience and they can react faster to prevent the accident. However, there are different solution for this issue. For instance, firstly the government should try to improve the road condition they should repair the road every few years because the road are exposed by sun and sun have a destructive effect on road. Secondly, driving policy should be more serious about rules and they should specify some heavy penalty for those who disobey the rules . and parents and adult should learn their children from the beginning they should respect rules and obey them to keep themselves and other safe from any accident . also there is an other way too that is driving policy get harder exam from those who wants to get their driving license. In conclusion, we should not deprived the young people from driving cars or motorbikes we should just increase the age and try to get other condition better than past to decrease the number of accident.

Except for doing homework, parents should limit the use of children under the age 13 on electronic devices such as computers and mobile phones. Agree or disagree? Nowadays, with considerable development in technology, electronic devices have become one of the significant parts of human life. In this regard, one of the contentious issues is whether parents ought to put some limitations for their children in the use of such devices for activities apart from education or not. Although some believe electronic devices can be inappropriate for children, I am opposed to this idea for some reasons which will be elaborated in the following. First, electronic devices make it possible for children to improve their social abilities. To explain more, these days, due to the increment in people’s responsibilities, the majority of individuals are preoccupied with their work duties and do not have enough free time to visit each other. As a result, people’s communications have diminished in comparison to the past. In this situation, children are not able to establish friendships and improve their social skills, so if they have permission to use their cell phone, they can talk to their friends about their problems and frustrations, thereby decreasing their stress. As an example, this year, owing to the pandemic, my family and I do not have any relationship with our relatives in person. When my parents regarded noticed my brother’s friendlessness producing some mental problems such as depression, they let him utilizing utilize his phone to have contact with his friends, which not only results resultedin his improvement in social skills, but also escalates escalated/elevated his mood and mental health. Second, electronic games improve children’s ability to work with such devices and be familiar with their possibilities. To clarify, since the world is moving forward in utilizing electronic devices and applications for numerous activities, such as education, shopping, and contacting with others, it is necessary for children to know various options of such instruments, and games provide this possibility. There are innumerable games on the internet designed in order to challenge children’s thinking abilities/cognitive abilities. In addition, because children mentally are ready to learn various matters and are curious, they will delve into different games developingflourishing their talents in this field. In sum, I believe the advantages of using electronic devices overweigh outweigh its demerits. It provides a proper opportunity for children to improve their communication skills. Moreover, it would be possible for them to display their special abilities in working with cell phones and become special in this area.

Living in Urban Areas

Around the world more and more people today are living in urban areas. Why is this? What problems does this cause? Cities are said to be the magnet of population. Industrialization and automation have enhanced mass production thus decreasing the necessity for untrained labour force. Consequently, the rate of migration from urban to rural areas hasis dramatically increased. This is an inherently neutral phenomena phenomenon but beneath the surface, complicated issues such as shanty towns, strain on infrastructure and cultural conflict have entangled the authorities. An increase in population is usually associated with high urban high growth which per se is a common source of other critical issues. Cities are overpopulated and cannot afford proper facilities to city dwellers. Due to lack of resources, the government attempts to control urban sprawl may fail and then unlicensed building would be ubiquitous. Naturally, not only is the appearance of the city but also the its culture of society is under pressure. A mixture of unemployment, drug and juvenile delinquency are the basic ingredients of nasty soup du jour in all shanty towns across the world. From the other point of view, environmental issues such as drought, famine, and lack of adequate percipiation precipitation force people to migrate to industrial zones in hope for of better possible job vacancies. For an inexperienced, illiterate workforce, big cities is are a mirage ultimately. Noting more than joblessness, drug and homelessness is their share of the cake of wealth in modern communities. Rarely can they contribute to society in a meaningful form. Crime and insecurity are rooted in cultural conflict, overpopulation and lack of proper education. Least I hope it does not lead to a point where the issue is addressed by immigration which per se is not a panacea but an incurable wound which is the source of other complex issues which the stench of whichthe problem has filled slum areas. Were I to choose between life in a big city of a small one, I would rather the second none. However, decentralization and equality should be moved to the forefront of the agenda. If facilities are designed for a socioeconomically balanced plan, concentration of population in megacities is meaningless.

Mana Jamei, Tackle Crime

One of the most serious problems that cities now face is crime. What are the most effective measures to tackle crime in urban areas? In the present day, cities are strewn with a great deal ofnumerous difficulties, ranging from traffic congestion to committing violent felonies such as murder. There is no consensus as to what is the single most important issue cities are confronting; however, crime is one of the most challenging ones, and without a shadow of a doubt it should be high on the governments’ agenda. Innumerable means do exist with the aim of cutting crimes, though it is noteworthy that there is more to combating crimes than fining offenders or imprisoning felons; hence the importance of prospecting for more pragmatic approaches. Perpetrating offences, either misdemeanors such as traffic offence or felonies such as homicide, is inextricably linked to (having ?) a low socio-economic stratum; indeed, poverty breeds crime. Given that, alleviating poverty in society is integral to reducing crime statistics. Consider, for example, the head of a household grappling with fiscal issues and has having a slim hope to enlist government’s financial support, is he or she more liable to larceny or those who have a lot of money to burn? By the same token, education is another deterrent of fundamental efficacy. If city leaders aim to tackle escalating crimes and nip them in the bud, they ought to make every effort to ensure that the youth are being bestowed due education, lest they grow juvenile delinquents. Tutoring young charges can pave the way for inculcating the respect for people’s rights in their minds, so as not to violate those rights by engaging in crimes such as burglary- a violation of property rights- or even homicide- a violation of the right to life. Last but not least, rewarding law-abiding citizens might be a more decent practice than fining lawbreakers in that possessing a genuine incentive, such as a tax incentive or a reduction in one’s car insurance payment, can act as a stronger crime deterrent than a fear of penalties. The main conclusion to be drawn is that in this writer’s view among various measures that can be taken, education and overcoming poverty is are of the essence to prevent crime. 348 words

There are many different types of music in the world today. Why do we need music? Is the traditional music of a country more important than the international music that is heard everywhere nowadays? In recent decades due to the mass media and global village we are familiar with various kinds of music. The same as other types of art, music was a part of the human history. Recently some kinds of it have become became more popular which is are known as international music. Some individuals believe that we should give more value to local or folkloric music. In my opinion, valued valuing traditional music could be a way of protecting a part of a culture that is important. In my view, music is all around us that is coming from nature. The sound of rivers, wind, birds and even an elephant is a piece of music. It has been with us since for ever. It is with us when we are happy or sad. We listen to music in every single event of our life. In birth and death, in a wedding or graduation, or in the New Year’s Eeve. Even if there is no instrument or electric device people will start singing and clapping. Music has such a vital role in our life that is impossible to imagine humans’ life without musicit. We communicate via this art form/music without knowing a common language. We use music it to send profound messages to each other. It seems to me, music is food for our soul. By listening to different kinds of music we try different cuisines. Also, music is one of the main elements of any culture. We learn about a nation and community through their folklore music. People express and share their thoughts, believes beliefs and emotions via music. Thus, it is crucial to introduce traditional music to the young generation in order to teach them about their roots, culture, and social values. There is a concern that every dayattracting more and more adolescents into international music can lead to abolishing traditional music, and thereby eliminating a part of a unique culture. As a result, international music has many advantages for instance, it unites people throughout the world with different cultures, languages, and religions and makes them closer. On the other hand, it can damage local cultures as well. To address this issue, international festivals for traditional bands and music videos which with different nations cooperating could be constructive. With + noun + verb-ing Task 1 The charts show the results of a survey of adult education. The first chart shows the reasons why adults decide to study. The pie chart shows how people think the costs of adult education should be shared. The figures illustrate data came out of a survey of adult education. The bar chart indicates elements which motivate adults decide to study. Also, the pie chart indicates individuals’ idea about the way of sharing the costs of adult education. Overall, the bar chart shows that interest in subject is the main reason people decide to study by 40 percent. In addition to this, to gain qualifications is the second main reason with merely a slight difference by 38 percent. Also, the last reason adults decide to study is to meet people with only 9 percent. To improve prospects of promotion and enjoy learning and studying both with 20 percent are the other factors that motivate people to study. Moreover, helpful for current job by 22 percent is another reason that adult decide to study.In addition to all, the pie chart shows that people think that the costs of adult education must be paid 35 percent by employer, 25 percent by taxpayer, and only 40 percent by individuals.

Do you agree or disagree with the following statement? Overall, the widespread use of the Internet has a mostly positive effect on life in today’s world. In today’s fast-paced technological development, digital advances play a significant role. Internet as the pioneer of this progress has been dominated the world. Although some individuals warn of the probably negative impacts, I believe that the Internet and its merits have a positive effective effectively affected our lives. I feel this way for two reasons which I explore in the following essay. To begin with, fast-speed Internet has saved thousands of minutes of the world’s s’ population until now. Every aspect of our lives directly is linked to the Internet. For instance, people can search, order and receive any goods of their needs in a fraction of a second just using some googling and clicking on the Internet. Even paying the bills and taxes are now online. Saving citizens from transporting and getting stuck in heavy traffic congestions in a crowded city in order to purchase commodities is one of the advantages that the Internet has brought to us. As a personal experience, I do the majority of my bank transactions and buy necessities online while I am busy with my job early in the morning and get the goods at the end of the day . After work, I go directly home, avoiding wasting time in rush hour traffics; instead, I can dedicate the mentioned time for watching a good movie. Furthermore, the Internet actively helps to thrive in science and technology by connecting research worldwide so fast and easily. The results and arguments can be shared and discussed in a digital environment , no matter how far the distances are. Moreover, nowadays , not only do the researchers have access to the mutual experiments of their other counterparts, they can also hold scientific webinars online at the same time without bothering with long-distance travelling. As an illustration, finding a cure or vaccine for the recent pandemic rapidly, several researches have been conducting conducted by many universities around the world simultaneously and the only connection was through the Internet. Consequently, three vaccines were discovered successfully in different parts of the world. In conclusion, I firmly believe that the Internet and its worldwide positive influences are among the best facets of human lives. The reason is saving the precious time of citizens and the significant role in developing the research and science.

A distributively novel robust data-enabled predictive control is introduced in [1] that utilizes noisy data of the system and produces optimal control inputs which enforce satisfying desired output chance constraints with high probability. This proposed method is applied on voltage source converter based high-voltage DC (HVDC) stations in purpose of damping the oscillations in power systems given that in practice an accurate parametric model of these systems is rarely available. A data-driven model predictive control scheme is proposed in [2] which only requires an initially measured input-output trajectory together with an upper bound on the order of the unknown system. In [3], a methodology has been developed in order to make a single-input single-output system stable merely based on data. The Stability problem for back-box linear switching systems is investigated In [4] based on collected data, and for a desired confidence. As an extension of this work, a methodology is provided in [5] in order to compute invariant sets of discrete time-invariant black-box systems. A novel Bayes-adaptive planning algorithm for data-efficient verification of uncertain Markov decision processes is introduced in [6]. A framework is proposed in [7] to provide a formal guarantee on data-driven model identification and control synthesis. In [8] a methodology is developed to the extent of providing a probabilistic confidence over the verification of a signal temporal logic property for partially unknown stochastic systems based on collected data. In recent years, some attempts have been conducted in order to combine the concept of barrier certificate with data-driven techniques in order to address a wide category of problems that for which there is no accurate model of the system. An optimization-based approach is suggested in [9] to learning a control barrier certificate through safe trajectories under suitable Lipschitz smoothness assumption on the dynamical system. A sublinear algorithm is developed in In [10] for barrier-based data-driven model validation of dynamical systems which computes the barrier function using large datasets of trajectories. In [11], a two-step procedure is proposed to synthesize a controller for an unknown nonlinear system, in which, in the first step, a Gaussian process is used in order to learn the nonlinear dynamics, and in the second step, a systematic approach is proposed to constructing the controller barrier function.
