Genetic Algorithms And Its Applications Of Cyber Security

Genetic Algorithms and its Applications to Cyber Security Paper By Sameera Chalamalasetty Guided By Dr. Mario A Garcia Abstract: Genetic algorithms (GAs) were initially proposed by John Holland, whose thoughts were connected and developed by Goldberg. GAs are a heuristic pursuit procedure in view of the standards of the Darwinian thought of survival of the fittest and characteristic genetics. Holland s work was basically an endeavor to numerically comprehend the versatile procedures of nature, however the general accentuation of GA examination from that point forward has been in discovering applications, numerous in the field of combinatorial enhancement. Genetic algorithms have been utilized as a part of science and engineering as versatile algorithms for tackling functional issues and as computational models of common developmental frameworks. In the latest couple of decades, this procedure with advancement of cutting edge development has accomplished something new. Introduction: â€Å"Li [3] describes genetic algorithm as a family of computational models based on evolution and natural selection.† â€Å"Bobor [4] has defined a genetic algorithm as a programming technique, which mimics biological evolution as a problem solving approach.† â€Å"An earlyShow MoreRelatedIntrusion Detection System ( Ids )2049 Words   |  9 PagesAbstract—Increasing attacks and intrusion of the Internet and computer systems necessitate the need for Intrusion Detection System (IDS) to prevent attacks. Genetic Algorithm (GA) is applied to support IDS.

Succubus Dreams CHAPTER 24 Free Essays

I knew I was going to live forever, but sometimes I had a hard time really understanding how long forever was. During that ride to the airport, however, I got a taste of what eternity might feel like. Maddie spent almost the entire time talking about Seth. We will write a custom essay sample on Succubus Dreams CHAPTER 24 or any similar topic only for you Order Now In fact, I’m pretty sure the only time she didn’t was when she stopped to check her watch and ponder whether we would make it on time. I knew we would make it on time because I would stop the car and carry her on my back before I’d risk her missing her flight and needing to ride back with me to the city. Once she’d decided we were still okay with time, it was back to Seth. Seth, Seth, Seth. I’m pretty sure there were only about three people in the world I wouldn’t have suspected of fucking with me if they’d come telling a story like this. Unfortunately, Maddie was one of them. She was telling the truth. It was written all over her, and something in me – maybe the part that really understood how serious the fight between Seth and me had been – could feel it. After a while, my mind sort of went numb, and I stopped thinking about it all. I finally dropped her off at the airport and went home, barely aware of the traffic I once again had to fight my way through. When I got back to my apartment, I ate dinner and watched A Christmas Carol. A long, hot bath followed, and five shots of vodka finally put me down for the night. I slept on the couch because I couldn’t bear to go in the room where an angel had fallen. Some Christmas Eve. Seth came over the next morning to take me to dinner at Terry and Andrea’s. Uneasiness radiated around him, but he still smiled when he saw me. â€Å"You look great.† â€Å"Thanks.† I knew I did. I’d spent two hours getting ready, the last thirty minutes of which had been me simply standing in front of the mirror. I’d stood there, taking in every detail of my appearance. The clinging red dress. The curve of my neck under the glittering black choker. The way my golden-brown hair, worn sleek and smooth today, hung down my back. Gold eye shadow and black liner framed my eyes. My lips glowed under pale peach lip gloss. Even at five-four, my legs looked long and supple. My face, carved with high cheekbones and flawless skin, was beautiful. I was beautiful. Call it vanity or egotism, but it was true. I was so, so beautiful. More beautiful than Maddie. More beautiful than any mortal woman. Staring at that gorgeous reflection, I begged it to tell me that Seth would want me. He had to want me. How could he not? But I knew all the beauty in the world couldn’t mask the pain in me. And after a couple more moments, Seth noticed too. His smile vanished. â€Å"How did you find out?† he asked. I dropped the coat I’d been holding. â€Å"How do you think? She told me. She couldn’t wait to tell me.† He sighed and sat on the arm of my couch and stared into space. â€Å"That’s it? You have nothing else to say?† I asked. â€Å"I’m sorry. God, I’m really sorry. I didn’t mean for you to find out like this.† â€Å"Were you ever going to tell me?† â€Å"Yeah†¦of course.† His voice was so sweet and so gentle that it momentarily defused the anger that wanted to explode out of me. I stared at him, looking hard into those amber brown eyes. â€Å"She said†¦she said you didn’t drink, but you did, right? That’s what happened?† I sounded like I was Kendall’s age and suspected I wore the pleading expression Yasmine had given Jerome. Seth’s face stayed expressionless. â€Å"No, Thetis. I wasn’t drunk. I didn’t drink at all.† I sank down into the armchair opposite him. â€Å"Then†¦then†¦what happened?† It took a while for him to get the story out. I could see the two warring halves within him: the one that wanted to be open and the one that hated to tell me things I wouldn’t like. â€Å"I was so upset after what happened with us. I was actually on the verge of calling that guy†¦what’s his name? Niphon. I couldn’t stand it – I wanted to fix things between us. But just before I did, I ran into Maddie. I was so†¦I don’t know. Just confused. Distraught. She asked me to get food, and before I knew it, I’d accepted.† He raked a hand through his hair, neutral expression turning confused and frustrated. â€Å"And being with her†¦she was just so nice. Sweet. Easy to talk to. And after leaving things off physically with you, I’d been kind of†¦um†¦Ã¢â‚¬  â€Å"Aroused? Horny? Lust-filled?† He grimaced. â€Å"Something like that. But, I don’t know. There was more to it than just that.† The tape in my mind rewound. â€Å"Did you say you were going to call Niphon?† â€Å"Yeah. We’d talked at poker†¦and then he called me once. Said if I ever wanted†¦he could make me a deal. I thought it was crazy at the time, but after I left you that night†¦I don’t know. It just made me wonder if maybe it was worth it to live the life I wanted and make it so you wouldn’t have to worry so much.† â€Å"Maddie coming along was a blessing then,† I muttered. Christ. Seth had seriously considered selling his soul. I really needed to deal with Niphon. He hadn’t listened to me when I’d told him to leave Seth alone. I wanted to rip the imp’s throat out, but my revenge would have to wait. I took a deep breath. â€Å"Well,† I told Seth. â€Å"That’s that. I can’t say I like it†¦but, well†¦it’s over.† He tilted his head curiously. â€Å"What do you mean?† â€Å"This. This Maddie thing. You finally had a fling. We’ve always agreed you could, right? I mean, it’s not fair for me to be the only one who gets some. Now we can move on.† A long silence fell. Aubrey jumped up beside me and rubbed her head against my arm. I ran a hand over her soft fur while I waited for Seth’s response. â€Å"Georgina,† he said at last. â€Å"You know†¦I’ve told you†¦well. I don’t really have flings.† My hand froze on Aubrey’s back. â€Å"What are you saying?† â€Å"I†¦don’t have flings.† â€Å"Are you saying you want to start something with her?† He looked miserable. â€Å"I don’t know.† No. This wasn’t happening. â€Å"What’s this mean for us?† I asked. â€Å"I don’t know.† The anger returned, and I leapt up, much to Aubrey’s annoyance. â€Å"What do you know?† I demanded. â€Å"Do you even know why you did this?† â€Å"There were a lot of things going on†¦Ã¢â‚¬  he said. â€Å"A lot of factors. It just happened†¦Ã¢â‚¬  I put my hands on my hips and stalked toward him. â€Å"Did it? Did it really? Because I’m not so sure.† His distraught expression turned wary. â€Å"What’s that mean?† â€Å"I think you were getting back at me for not giving in that night. I made you mad. I hurt you. So, you’re trying to hurt me. Teach me a lesson.† â€Å"I – what? Are you insane? You think I’d do something like this to teach you a lesson? You think I would want to hurt you? Just because you refused sex?† â€Å"Why not?† I asked. â€Å"Guys always want sex from me. Why are you any different?† â€Å"Georgina,† he said incredulously. â€Å"You can’t believe that. It’s always been about more than sex. You have to know that. I’ve told you that over and over. I would never purposely hurt you. And yet†¦Ã¢â‚¬  â€Å"And yet what?† He looked away from me and focused on the carpet. â€Å"I don’t know that we can keep going on without me hurting you.† â€Å"Well, if you don’t sleep with my friends – â€Å" â€Å"It doesn’t even have to be that. There are so many things it could be. I could get hit by a car tomorrow or catch some disease. If you ever do crack some day and sleep with me, you’ll hate yourself forever. And if I crack and sell my soul, that’s going to upset you too. One way or another, you will get hurt. It’s just a matter of when. I saw it that night in the kitchen – I saw your face when you were yelling at me. That’s when I knew it was all true.† â€Å"I†¦I was upset,† I told him. â€Å"And, I mean†¦we knew this relationship wouldn’t be easy. You were okay with all this in the beginning†¦the sex and everything else†¦.† â€Å"Things change,† he said bluntly. He met my eyes, and I again saw warring sides within him. â€Å"And back then, I thought I was the one who would get hurt, not you. I can handle it.† â€Å"Are you saying I can’t?† â€Å"I’m saying I don’t want to find out. And honestly, it’s not even about sex either. We’ve got communication problems, time problems†¦I don’t know. Hell, we have death problems. I don’t really know if we should keep doing this.† It felt like Joel’s death again, like all the energy was being sucked away from me. â€Å"How,† I demanded, â€Å"can you always lecture me about open communication and then dump this on me now? If you were feeling all this†¦you should have brought it up beforehand, not in some bluff break-up at the zero hour.† â€Å"I’m not entirely sure what that last part meant, but I’m not bluffing. And I’ve tried to talk to you about this. I tried the night you massaged me – you didn’t want to hear it.† Seth took a deep breath. â€Å"Georgina†¦I really mean it. I don’t think we should be together anymore.† I gaped. No, this wasn’t right. This wasn’t right at all. I’d expected a big fight, one we’d eventually get over, like always. I’d expected him to ask for forgiveness. I’d expected to set new boundaries in the relationship. I’d expected me to be the one to have the high ground and decide if we were going to continue this. I hadn’t expected to be pleading. â€Å"No. No. Seth†¦we’ve just got to make it work. Look, I’ll get over Maddie, okay? And if you want to sleep with other women†¦I mean, it is okay. I always said you could. It’s just this first time†¦well, it’s a shock, that’s all.† He just continued to watch me quietly, and I found myself babbling on more and more. â€Å"But we can make it work. We always do. We’ll find a way. You can’t just go ahead and decide something like this on your own. There are two of us in this, you know.† â€Å"Yeah,† he said. â€Å"I do know. And I’m one of the two. And I want to split up.† â€Å"No,† I said frantically. â€Å"You don’t want to. This is just some weird†¦I don’t know. You don’t mean it.† Seth’s silence was more infuriating than if he’d shouted back at me. He just kept watching me, letting me talk. His expression had so much regret – but so much determination too. â€Å"You were the one who told me we could overcome anything,† I cried. â€Å"Why not this?† â€Å"Because it’s too late.† â€Å"It can’t be. If you do this†¦it’s all for nothing†¦you’ll have ended up hurting me. Me and Maddie both.† â€Å"It’s a small hurt compared to what could really happen,† he said. â€Å"And as for Maddie†¦I don’t plan on hurting her. I†¦I like her.† â€Å"But you love me.† â€Å"Yeah, I do. I probably always will. But maybe that’s not enough. I have to move on. We can’t do this. I think maybe†¦I don’t know. I think something good could happen with me and Maddie. In some ways, she’s like you, only – â€Å" Seth had started to slip into the rambling he sometimes did when nervous enough. He bit his lip now, as though he might summon the words back, and looked away. â€Å"Only what?† I asked. I could barely hear my own voice. He turned his gaze back to me, firm and unflinching. â€Å"Only†¦more human.† And that was it. All the anger and sorrow vanished. There was nothing in me. Nothing at all. I was empty. â€Å"Get out,† I said. He paled. Something in my voice and expression must have been truly terrifying. Tentatively, he extended a hand. â€Å"I never meant to hurt you. Thetis, I’m sorr – â€Å" â€Å"Don’t ever call me that again,† I told him, stepping away. I didn’t know how any of these words were coming out of my mouth. It was like someone else was controlling me. â€Å"Leave. Now.† He opened his mouth, and I thought all that resolve he’d just shown might crumble. In the end, it didn’t. He left.

Manage Work Health and Safety-Free-Samples for Students-Myassignment

Question: Discuss about the Manage Work Health and Safety. Answer: Introduction This presentation forms the basis of the induction program, and we are going to cover with my two colleagues herein the various topics of work safety and health. During this presentation it is important to note that the following topical issues will be addressed; roles and responsibilities of workers in an organization, work safety and health standards and codes of conduct, case study emergency presentations, circumstances in case study emergencies, access of emergency staff policies and procedures, application of emergencies guidelines, reporting and documentation of emergencies, record keeping of emergencies, obligation of organizations during emergencies and organization follow up of emergencies in an organization. Roles and responsibilities of workers in an organization As support workers in the disability home, staffs are responsible for supporting residents in the facility based on their own needs based on the environment they live in. Activities of support revolve around daily living skills, care, travelling escorts within and outside environment, teaching of the life skills which aid on their mobility and effort, participating in leisure activities and work placements. Trends of organization have shown that work organization may affect workers health , (Sawacha, Naoum Fong, 1999).The organization is task at providing user friendly environment to facilitate the help for the disable and needy clients. The organization needs to facilitate the use of equipments such as lifts or swivel cushions to assist the clients, effective communication technology for easier service delivery and provision of vehicle modification tools such as wheelchairs to aid in mobility movement. WHS legislation, regulations, standards and codes of conduct Workers are guided by the Workers Health and safety standards in an aim of securing their health and safety of the workers, (Robson et al., 2007). It does so by protecting the workers from harm to their safety and health, provide fair and effective workplace representation, encourage provision of advice, information and education to the workers, providing frameworks for continuous improvement and maintaining harmonious relationships of work and safety guidelines. As health care workers, there is need for understanding the sets standards which are expected from health care support workers and adult social workers in this organization, (Trner Pousette, 2009). The guidelines outline the behaviour and attitudes that are accepted from workers who sign up for the code. The codes have acted as a voluntary however it serves as sign of best practice in the organization. Emergency presentation from the case study and their circumstantial events The first emergency situation presentation in the case revolves around 3 cases of emergency, and the first one involves resident who happens to be a disable patient who runs on the wheel chair and has fallen. The resident rushes to the worker staff seeking help for assistance on the disable resident. The second emergency incidence revolves around a resident who has just incurred a spider bite. The role of the worker at this critical point is that they are supposed to calm the residents and calm the victim, as they prepare to roll out first aid, however as the worker tries to manage the resident, he gets out of hands and runs towards the gate and manages to open the closely tight gate and tries to escape. As things roll out the third emergency incidence occurs whereby, as the resident tries to get out of the gate, there is emergence of men in black entering the facility with guns pointing towards the residents. Everyone gets chilled and everyone surrenders. However as it turned later, we found out that they were federal police who thought that there was something suspicious happening. Access of emergency policies and procedures Emergency policies and guidelines are brief and simple guidelines which guide the employees in case of emergency events, (Parmeggiani et al., 2010). As workers there are need to know duties and responsibilities for actions to be taken in case of an emergency. There is need for keeping the first aid kit, attendance record and emergency information card for recoding and always keep within reach of easy access. As a staff there is need to endure that you understand the emergency evacuation plan and procedures in case of an emergency situation. Clear communication protocol should be always established and easily available for the staff to access in case there is an emergency. As a staff, in the organization availability of these manuals serves the best effort to guide. Emergency procedures to employ in the case studies The emergency procedure to be used for this resident is that there is need to transfer the victim on the chair as soon as possible with delicate handling. This depends on the upper body strength, as a worker there is need to assist the wheel chair user by trying to avoid putting much pressure on the extremities of the victim like the chest; this can cause spasms and pain and hinder breathing. The second incident is of spider bite, actions to initiate is to calm the patient as soon as possible, clean the wound with mild soap and water and apply an antibiotic available in the first aid kit in the organization emergency section and further a damp cloth can be applied on the cloth filled with ice so as to reduce the pain. After pain relief administer over the counter drugs to relive the pain. Emergency procedure for incident three is to ensure that there is calm and take precaution as soon as possible. As the armed men enters, advices everyone to stay calm and not to run away as they can endanger their lives. Be calm and confront the men gently and inform them of the organization so as not to cause harm, while other workers can call for emergency help if not at the vicinity of the incident. Reporting and documentation of emergencies Hazards in the workplace can be reported in a variety of ways. Information gathering process to generate a situation is crucial during emergencies, (Oral et al., 2003). As a health worker in the organization, hazard and emergencies like those presented in the case study, can be handled through verbal reporting, completion of hazard report forms and raising the issue during staff meetings of the organization. Acute emergencies should be reported immediately, while those that are less acute can done through completion of hazard reporting for. Also the organization has specific procedure of how to report emergency situations and is available in the emergency reporting manual. In this case during the incident report three, the director needs to be informed as this has tremendous effects and impacts on the employees as they may think they are targeted. Obligations of organizations in emergency situation The organization has the sole responsibility of providing work environment free from hazards and to ensure that staff health and safety is assured for the staff, (Daynes, 2006). In emergency situations, employers have the responsibility of ensuring that relevant workplace health and safety are adhered to. There is need to follow effective ways of managing exposure risks and emergency cases as reported in the case studies. After emergency situations the organization has to undertake supporting risks and control procedures. The staffs have key responsibility in health and safety by being actively engaged in the hazard identification and assessing the risks. Thus it is important to take through the staff on the strategies such as think, talk, act or review process of emergencies. They think of hazards, taking with those who have knowledge of the incident, act in a manner that reports hazard levels and reviewing controls put in place to reduce the risks. Conclusion From the above description the case study illustration has underpinned relevant concepts with regard to handling of emergencies and the roles of and responsibilities of employees of work place in organizations. Mindful adherence of policy procedures with regard to workers health and safety is crucial in ensuring that right procedures are followed while maintaining clear emergency procedures.

Photography Is A Technique Of Producing Permanent Images On Sensitized

Photography is a technique of producing permanent images on sensitized surfaces by means of the photochemical action of light or other forms of radiant energy. In today's society, photography plays important roles as an information medium, as a tool in science and technology, and as an art form, and it is also a popular hobby. It is essential at every level of business and industry, being used in advertising, documentation, photojournalism, and many other ways. Scientific research, ranging from the study of outer space to the study of the world of subatomic particles, relies heavily on photography as a tool. In the 19th century, photography was the domain of a few professionals because it required large cameras and glass photographic plates. During the first decades of the 20th century, however, with the introduction of roll film and the box camera, it came within the reach of the public as a whole. Today the industry offers amateur and professional photographers a large variety of cameras and accessories. See also Motion Picture. The Camera and Its Accessories Modern cameras operate on the basic principle of the camera obscura (see Historical Development, below). Light passing through a tiny hole, or aperture, into an otherwise lightproof box casts an image on the surface opposite the aperture. The addition of a lens sharpens the image, and film makes possible a fixed, reproducible image. The camera is the mechanism by which film can be exposed in a controlled manner. Although they differ in structural details, modern cameras consist of four basic components: body, shutter, diaphragm, and lens. Located in the body is a lightproof chamber in which film is held and exposed. Also in the body, located opposite the film and behind the lens, are the diaphragm and shutter. The lens, which is affixed to the front of the body, is actually a grouping of optical glass lenses. Housed in a metal ring or cylinder, it allows the photographer to focus an image on the film. The lens may be fixed in place or set in a movable mount. Objects located at variou s distances from the camera can be brought into sharp focus by adjusting the distance between the lens and the film. The diaphragm, a circular aperture behind the lens, operates in conjunction with the shutter to admit light into the lighttight chamber. This opening may be fixed, as in many amateur cameras, or it may be adjustable. Adjustable diaphragms are composed of overlapping strips of metal or plastic that, when spread apart, form an opening of the same diameter as the lens; when meshed together, they form a small opening behind the center of the lens. The aperture openings correspond to numerical settings, called f-stops, on the camera or the lens. The shutter, a spring-activated mechanical device, keeps light from entering the camera except during the interval of exposure. Most modern cameras have focal-plane or leaf shutters. Some older amateur cameras use a drop-blade shutter, consisting of a hinged piece that, when released, pulls across the diaphragm opening and exposes the film for about 1/30th of a second. In the leaf shutter, at the moment of exposure, a cluster of meshed blades springs apart to uncover the full lens aperture and then springs shut. The focal-plane shutter consists of a black shade with a variable-size slit across its width. When released, the shade moves quickly across the film, exposing it progressively as the slit moves. Most modern cameras also have some sort of viewing system or viewfinder to enable the photographer to see, through the lens of the camera, the scene being photographed. Single-lens reflex cameras all incorporate this design feature, and almost all general-use cameras have some form of focusing system as well as a film-advance mechanism. Camera Designs Cameras come in a variety of configurations and sizes. The first cameras, ?pinhole? cameras, had no lens. The flow of light was controlled simply by blocking the pinhole. The first camera in general use, the box camera, consists of a wooden or plastic box with a simple lens and a drop-blade shutter at one end and a holder for roll film at the other. The box camera is equipped with a simple viewfinder that shows the extent of the picture area. Some

Avogadros Law Example Problem

Avogadros Law Example Problem Avogadros gas law states the volume of a gas is proportional to the number of moles of gas present when the temperature and pressure are held constant. This example problem demonstrates how to use Avogadros law to determine the volume of a gas when more gas is added to the system. Avogadro's Law Equation Before you can solve any problem regarding Avogadros gas law, its important to review the equation for this law. There are a few ways to write this  gas law, which is a mathematical relation. It may be stated: k V/n Here, k is a proportionality constant, V is the volume of a gas, and n is the number of moles of a gas. Avogadros law also means the ideal gas constant is the same value for all gases, so: constant p1V1/T1n1   P2V2/T2n2V1/n1   V2/n2V​1n2   V2n1 where p is pressure of a gas, V is volume, T is temperature, and n is number of moles. Avogadro's Law Problem A 6.0 L sample at 25 °C and 2.00 atm of pressure contains 0.5 mole of a gas. If an additional 0.25 mole of gas at the same pressure and temperature are added, what is the final total volume of the gas? Solution First, express Avogadros law by its  formula: Vi/ni Vf/nfwhereVi initial volumeni initial number of molesVf final volumenf final number of moles For this example, Vi 6.0 L and ni 0.5 mole. When 0.25 mole is added: nf ni 0.25 molenf 0.5 mole 0.25 molenf 0.75 mole The only variable remaining is the final volume. Vi/ni Vf/nf Solve for Vf Vf ​ Vinf/niV​f (6.0 L x 0.75 mole)/0.5 moleVf 4.5 L/0.5 Vf 9 L Check to see if the answer makes sense. You would expect the volume to increase if more gas is added. Is the final volume greater than the initial volume? Yes. Doing this check is useful because it is easy to put the initial number of moles in the numerator and the final number of moles in the denominator. If this had happened, the final volume answer would have been smaller than the initial volume. Thus, the final volume of the gas is 9.0 Notes Regarding Avogadro's Law Unlike Avogadros number, Avogadros law was actually proposed by   Amedeo Avogadro. In 1811, he hypothesized two samples of an ideal gas with the same volume and at the same pressure and temperature contained the same number of molecules.Avogadros law is also called Avogadros principle or Avogadros hypothesis.Like the other ideal gas laws, Avogadros law only approximates the behavior of real gases. Under conditions of high temperature or pressure, the law is inaccurate. The relation works best for gases held at low pressure and ordinary temperatures. Also, smaller gas particles- helium, hydrogen, and nitrogen- yield better results than larger molecules, which are more likely to interact with each other.Another mathematical relation used to express Avogadros law is: V/n k Here, V is the volume, n is the number of moles of the gas, and k is the proportionality constant. Its important to note this means the ideal gas constant is the same for all gases.

Comparative - Essay Example Surprisingly, during summer, there is no single city out of the two that can be said to have a hot climate. Vancouver (128) is referred to as one of the warmest Canadian cities and so is Qing Dao (150) which is also known one of the temperate cities in China. During the summer seasons, you will find many people basking the sun in the morning and enjoying the fresh breeze everywhere in the evening. In addition, the beaches of the two cities are normally packed with lots of children whom their parents bring out to have fun. You will find many families down at the beach having barbeque parties. For that reason, summers in those cities have even been named ‘the barbeque season’ (130). However when it comes to the winter season, this is completely another different phase between the two cities. Vancouver has the mildest winter conditions among the Canadian cities (131). The rain goes for eight to nine months of heavy rainfall. I do not like the winter period as the rain plagues my heart and the atmosphere is usually lazy. It is even normal for people to get late for work or events since clouds are usually gloomy during the lethargic weather drawling more sleep and less activities. Astonishingly, the situation in Qing Dao is different on winter (150). The weather is rarely somber and the springs and autumn are much clearer. Back in Qing Dao, I used to have winter and spring outings which I cannot do that here. Having outlined the weather in both cities, I prefer Qing Dao to Vancouver. Another appealing thing I found amusing between the two cities is the food. The food here in Vancouver is very impressing. I used to feed on unadulterated Chinese food back in China. I was afraid that I could not get that same kind of food here but to my surprise, I stumbled several restaurants in Richmond that had identical food as to China. In addition, I have discovered many types of food here like the Japanese, Italians, French, Pakistani and Thai. I have to agree from the
