Do something the wrong way 10-15 times and it becomes a habitual behavior. They exhibited better balance and motor coordination, eye contact improved and play skills were further developed. Greater self-esteem was also reported, with the added bonus of these kids being able to defend themselves, if needed. † (University of Wisconsin, source 1, page 36, paragraph 1. ) Martial arts assist children on the autism spectrum because friend ships are formed around a shared activity and that sense of belonging can be the greatest reward of all for them. Martial arts also help children on the autism spectrum because the release of energy in a safe and ritualized environment can bring a child to a new sense of calm. Also martial arts assist children on the autism spectrum with the ability to concentrate and focus their attention in a consistent and highly structured environment. Additionally, parents find that new skills carry over in to home and at school. Spending time assessing each student to determine what is uniquely motivating for them. Remembering that it may be different than what motivates anyone else, and is definitely different than what motivates other students. For example sensory items, tearing paper, watching things move vs. social praise or time with friends. We then use those unique motivators to engage the student in the learning process. Important lesson of structured teaching is that individuals with autism learn best when they are interested and motivated. Treatment and Education of Autistic and related Communication handicapped Children (TEACCH) was developed in the early 1970’s by its founder, Eric Schopler, the Treatment and Education of Autistic and related Communication handicapped Children approach includes a focus on the person with autism and the development of a program around the person’s skills, interests, and needs. They observed people with autism and gained an understanding of their learning style and the characteristics that affected their learning and interactions. Based on their research and understanding of the characteristics of autism, Eric Schopler and others at Treatment and Education of Autistic and related Communication handicapped Children developed the concepts of â€Å"Structured teaching† as a way to help us organize the educational and home environment in a meaningful way for individuals with autism. People with autism have difficulty in focusing-over focus on details, misses the main idea or what is important now, both social and academically. They also have difficulty generalizing skills and knowledge, does not like change, wants things to remain the same and thrives with routines and structure. They do not change behavior to please others, not a flexible thinker, does not understand others views or choices available, easily struck. People with autism have literal understanding. Terms like you’re killing me, you crack me up, you are out of your mind, pull yourself together, if looks could kill, butter her up and computer bug are taken literal by them. Because of their degree of functionality and their naivete those with autism are often viewed as eccentric or odd and can easily become victims of teasing and bullying. Symptom’s of Asperger’s syndrome are markedly overactive, indicates needs by gestures, is not cuddly or does not like to be touched, easily upset by changes in routine, overly sensitive to loud sounds, lights or odors, fixated on one subject or object, physically awkward in sports. Social situations are extremely challenging, often unsuccessful, chooses to be alone, inappropriate topics, struggles to join and remain a part of a group. Children with Asperger’s syndrome have difficulty picking up nonverbal cues. Not all children with Asperger’s syndrome are alike. Just as each child with Asperger’s syndrome has his or her own personality, Asperger’s syndrome symptoms are manifested in ways specific to each individual. There are seven senses people have. Sensory system one is visual, the receptors are the eyes. Sensory system two is auditory, the receptor is the outer ear. Sensory system three is olfactory, the receptor is the nose. Sensory system four is gustatory, the receptor is the tongue. Sensory system five is tactile, the receptor is the skin. Sensory system six is proprioception, the receptor are muscles and joints. The last Sensory system is vestibular, the receptor is the inner ear. When children are in different moods it affects each of the seven senses. Children with ready to learn arousal. Vision: looks at the task in hand. Auditory: listens to directions effectively. Taste/smell: recognizes standard scent of materials. Tactile: touches all materials appropriately. Proprioception: uses body successfully to complete task. Vestibular: remains at own work station for entire task. For children with high arousal. Vision: frequently distracted by peers. Auditory: needs directions repeated. Taste/smell: driven to smell or licks all materials. Vestibular: constantly wandering away from work station. Proprioception: seems too rough with materials. Tactile: touches all materials and everyone else’s. To support children with high arousal. Vision: monochrome materials, position with back to the back. Auditory: slow clam tone. Taste/smell: juice box with narrow straw. Tactile: reduce variety of texture but increase volume, offer soft/silky. Proprioception: provide very resistive or even weighted materials, work against gravity. Vestibular: all materials positioned within reach, offer movement breaks that are calming. Children with low arousal. Vision: stares off into space. Auditory: needs directions repeated. Taste/smell: drools. Tactile: doesn’t explore materials. Proprioception: seems weak, can’t manage tools. Vestibular: doesn’t spontaneously move body to manage task. To support children with low arousal. Vision: bright contrasting colors, sit near the action. Auditory: vary intonation, loud. Taste/smell: several trips to the bubbler, scented materials. Tactile: add texture, change temperature. Proprioception: prepare for task with stretching. Vestibular: standing vs. sitting, position materials on floor. Meltdowns occur when the person is overwhelmed by the stimulation from; people, tasks, sensory input, emotions and environment. Meltdowns may include screaming, aggression, running away, panic attacks, severe withdrawal, or tantrums. During a meltdown no learning is happening. The main goal is to help the person regain self-control. Best is you can intervene before the meltdown occurs. Learn and look for signs that indicate person is becoming overwhelmed. The first time to do to manage a meltdown is to decrease stimulation/ increase personal space; stay calm and be supportive, decrease language and use visual supports. Physically intervene when safety is an issue, help the person get to a safe area to calm down if needed. You can prevent negative behaviors to be patient. Maintain visual supports, provide waiting time, and implement strategies. In lieu of conventional means of communicating, children with autism may develop idiosyncratic, unconventional, or inappropriate behaviors to communicate, such as self-injurious behaviors, aggression, or tantrums†. â€Å"Most children begin to pick up social and communication skills while they are still infants and toddlers. However, it is exactly this vast realm of communication and social understanding that typically escapes the person with autism. †(Jeanette McAfee, M. D. 2002, source 1, page 70, paragraph 1. ) Teach strategies using interests. When the strategy is understood, teaching a new skill that may be more challenging. Teach strategies using interests in calm relax environment. When the strategy is understood, teach a new skill that may be more challenging. Many individuals are still learning fundamental skills to be a part of a group. Skills that are needed for independences are to ask for help, ask for clarification, recognizing and understanding emotions, request a break, know when and how to take a break and utilize a schedule. Teaching the concept of time. Teach with a transition that is not difficult for the child. Teaching help involves teaching life skills, creating opportunities with low frustration, have visuals easily accessible, praise success in a manner that is rewarding to the person. Develop relationships with growth potential. Everyone has something to teach us, that don’t mean that everyone can teach us everything we want to learn. The people we associate with the most will rub off on us the most. Learning and growing is often the reward for spending time with remarkable people. Identifying people’s uniqueness and strength, we all have qualities and strengths that are part of our natural make-up. These areas will be the areas that we all learn and grow the most. We can surround ourselves with the people that have strengths that can complement our own. Whenever we meet someone new, we are exposed to new learning. It’s been said that we have one mouth and two ears because that way it is encourages us to listen twice as much as we talk. People don’t learn well people they don’t value. If you truly value people you’ll be able to learn from everyone; younger, older, more experienced, less experienced. If you have a teachable attitude, or are willing to adopt one, you will be well positioned to learn the most you can from others. Martial arts is a perfect atmosphere and environment for the development of leadership skills. It has a built in ranking system, as well as opportunities to earn titles and positions that empower people to leader others. Three areas that can immediately improve to increase our influence and improve our image as a leader is appearance, attitude, and actions. Always remember that the title and position doesn’t make the leader, the leader makes the title and position. People will always respect and admire the person far greater then they will respect and admire the title or position. You can have everything in life you want, if you help enough other people get what they want! † (Zig Ziglar, source 3, page 1 paragraph, 5) All us of can learn things in unlikely places, and from unlikely people. Everybody has something to share, or something to teach us. But, that is only true if we have the right attitude toward learning and people. Being arrogant is like saying no one can teach me. The reality is that no one is too old, too smart or too experienced to learn something new. The only thing that stops any of us from being able to constantly learn and improve, is a bad attitude. Being naive is saying someone can teach me everything. People who realize they have room to grow will often seek a mentor. That’s usually a good thing. But not to fall into the trap of thinking that one mentor can teach you everything. Being teachable is saying everyone can teach me something. The people who are the most teachable are mostly to learn the most. Every person has something to share, an observation, a lesson learned, a life experience. We just need to be willing to listen and learn. The way how you influence people will determine how many, how long and how effective you will become at influencing them. People feel they are not able to influence others because they don’t have an official title or position of leadership. Position and title does not make the leader, the leader makes the position or title. Our values and significance increases when we influence others at a time they need it most. Great leaders have a high level of sensory acuity. Great leaders can sense the teachable moments, breakthrough opportunities, and the catalyst times. Right motives are crucial to maintaining a high level of trust in the relationships you have with people. Wrong motives are a result of bad character.

Bonnie and Clyde Essay Example

Bonnie and Clyde Paper At first glance Bonnie and Clyde is a story of crime involving two equal parts, but after some examination it is clear that the film is very much a story exclusively about the character of Bonnie. Clyde and other characters act as foils for Bonnie and never fully develop in the same way that she does. Bonnie evolves as the story progresses, and although she is very masculinized, her initial immaturity dissipates with her characters confusion of gender identity. The film opens with an extreme close up of Bonnie putting lipstick on her lips, a very deliberate idea of femininity. However, she is bored and aimlessly wanders around her room naked; she peers outside and sees Clyde attempting to steal her mothers car. She confronts him and ultimately she is convinced to go with him to lead a life of freedom and excitement. Her role as the woman perpetuates her fascination with Clydes reckless masculine quality but the role becomes unnecessary and extraneous after he admits that he is impotent, or not much of a lover boy. She eventually accepts her role as equal companion to Clyde in his endeavors and becomes very satisfied with such. We will write a custom essay sample on Bonnie and Clyde specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Bonnie and Clyde specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Bonnie and Clyde specifically for you FOR ONLY $16.38 $13.9/page Hire Writer For instance, when trouble starts to brew Clyde warns Bonnie that she aint going to have a minutes peace, to which she simply responds, You promise? Later, in her foreshadowing poem that she reads to Clyde, shes admits to her self that death is the only means by which she will be relieved of the burdens of the life of crime she has chosen. Clyde in turn becomes excited by the poem realizing how their story would become legendary with its printing; his sexual ineptness is evidently cured and all of a sudden he wants to marry Bonny in the next scene. This is the most telling scene of Bonnies transformation back to a character that wants a civilized life; she asks Clyde if he would do anything differently if they could have it all back. Bonnie is noticeably disappointed when he responds superficially and without any regard to a different lifestyle which Bonnie now longs for. Bonnie is also significantly foiled against the films other female character, Bucks wife Blanche. Bonnie is very assertive and lively whereas Blanche is reserved and polite in the scene when they meet each other. Bonnie is quick to grab Clydes gun and pose in front of the car in a very masculine way for the camera. Blanche doesnt want her picture taken at all, and when its done anyway, it is just of her and Buck with their arms around each other. By this point in the film Bonnie is at her peak of masculine quality, she is surprised and disgusted at how reserved and manner-aware Blanche seems to be. When the gang is in the cabin and the police confront them, Bonnie responds as quickly as the three men do fend themselves off from the police officers. Blanche proceeds to only scream and run away from the loud guns and, as they escape, Blanche is practically left behind until she frantically runs after the vehicle; Bonnie is clearly one of the guys, a true part of the gang and Blanche is only an afterthought even to her husband Buck. Additionally, Bonnies character is the only one in the film that is shown as having a family who she wants to be with, with the exception of Buck and Clyde. C. W. Moss foils Bonnie in the sense that his father plays a significant role in the film, but he doesnt go to him until he needs help, and it is in the best interest of the whole gang. Bonnie longs to see her mother, an indication that she may miss her old life; it may have been boring but it was also meaningful and safe. She slowly become dissatisfied with the life she hastily chose when she met Clyde. She does go home to her mother with everyone but only after trying to run away from the gang in order to do so; she has become so dissatisfied with the life that she doesnt even bother to warn Clyde of her departure, not wanting to bring the gang into her family atmosphere. Both C.W. Moss father and Bonnies mother are disapproving of their behavior, but whereas Mrs. Parker reaffirms Bonnies need for something more, old man Moss feelings of Bonnie and Clyde and their way of life only causes C. W. Moss anger and a lack of understanding. Bonnie Parker is slowly transformed from restless female to a gun shooting, money loving, masculinized character. By the end of the film it is too late for her to transform back despite wanting nothing more; she realizes that any life with Clyde would be a nomadic life of crime and must accept her fate as a gangster as she wrote about it in her own poem. Ironically, Bonnie is the only character who both wants out of the life, but also realizes that such an opportunity is an impossibility.

Gender discrimination essays

Gender discrimination essays In 1972, the United States Congress passed Title IX of the Education Amendment Act. This act banned sexual discrimination in education programs which received federal funding. In the area of athletics, it required universities which received federal funding to provide equal athletic opportunities for men and women. Still after over thirty years, women in sports still seek equality by the same treatment or opportunities that are given to males. Even though in the past few years, womens sports have increased in popularity forming new leagues such as the WNBA, a professional womens football league, womens soccer, and more. Sports in general is a mere reflection of society. In sport, people with the money have the power and make all the decisions. This leads to hegemony, where the powerful remain in control. In todays society, female sports do not get the recognition that mens sports do in that they do not make the same amount of money, the same amount of respect, and the same am ount of television coverage. Gender discriminations root comes from the interest and desires of society. The people in control, the older white males are biased towards male sports because the action is much faster and much more intense. This meets the desires and wellbeing of society, thus they will attend the male sporting events, watch the events on television, and buy their apparel from stores, thus solidifying the discrimination of female sports in favor of male sporting events. Female athletes are frequently looked upon as not being as entertaining or lacking athleticism compared to male athletes. The media has had the largest influence in socializing what we think about men and womens sports. Many people who are gender discriminative believe women are inferior to men in that they cannot compete on the same level, either intensity, performance, or stamina wise. These are reasons why female s...

TEXTBOOK CJ2012 FAGIN-Which philosophy of punishment do you believe in Essay

TEXTBOOK CJ2012 FAGIN-Which philosophy of punishment do you believe in and why - Essay Example 285). The theory of incapacitation, on the other hand, is founded on the philosophy that criminal circumstances must be negated so that the crime will not occur again while deterrence theory contends that the punishment awarded to an offender should be â€Å"sufficient to prevent future instances† of such crimes (285). Rehabilitation theory attempts to provide the offender a positive environment and creating awareness whereas restoration theory focuses on a restoring process by bringing the stakeholders together, with the offender taking responsibility for the offence and providing restitution to the victim. I believe restoration is the best approach because while refuting the effectiveness of other theories, it strives to bring positive outcomes for both the victim as well as the perpetrator. Punishments should rather address the crime than the criminal, especially in the context that an offender commits a crime not merely based on the faculty of free will. Several factors, such as biological, psychological and social influences contribute to criminal behavior in people. Therefore, punishments need to be focused on these causative elements rather than on the person who commits a crime. The approaches of vengeance and deterrence are found on the concept of punishing the perpetrator and not on eliminating the tendency to commit crimes. Thus, these may not yield any positive outcomes either for the person who commits the crime or the one who falls prey to it. Similarly, the philosophy of incapacitation also will not preempt a criminal from committing a crime, when the opportunity ripens. The concept of rehabilitation, focuses on providing positive environment for the criminal, and can be understood as a better approach than the other three. However, it does not guarantee a transformation of the offenders because they may embark on criminal behavior when the environment changes. Besides, it does not take into account the victim in any manner. On the other

Advantages And Disadvantages Of Networked Medium Information Technology Essay

Advantages And Disadvantages Of Networked Medium Information Technology Essay Bus networks use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message. Ring topology: In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction. A failure in any cable or device breaks the loop and can take down the entire network. Star topology: Many home networks use the star topology. A star network features a central connection point called a hub that may be a  hub,  switch  or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet. Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computers network access and not the entire LAN. b) Advantages and disadvantages of each medium. Network medium is the physical channel that used for transmission in the network. The types of the medium are: Wire Fiber air Wire: UTP cable is a medium that is composed of pairs of wires.  UTP cable is used in a variety of networks. Each of the eight individual copper wires in UTP cable is covered by an insulating material. In addition, the wires in each pair are twisted around each other. Fiber: Long distance signal transmission. Large Bandwidth, Light Weight, and Small Diameter Long Lengths Easy Installation and Upgrades Non-Conductivity Security Designed for Future Applications Needs Air: Mobility. Elimination of unsightly cables. c) Recommendation for topology and medium to use: Topology: Figure 1.1 : Star topology We select the star topology for this in-house network. Because the star topology is most popular topology for in-house network (LAN). Also we can be benefit by using the star topology in a LAN. Benefits: Information can be easily shared allowing for quick and informed decisions to be made, saving time and money. A more productive and competitive environment is achieved through greater teamwork within the organization. Network-based communication such as email is considerably cheaper than using the phone or fax and sharing resources such as printers gives more efficient use of equipment at lower costs. Standard versions of procedures and directories can be made accessible to everyone. IT administration can be centralised. Data can be backed-up from a single point on a scheduled basis ensuring consistency. Medium: Figure1.2: WI-FI network We select the WI-FI for this in-house network. Because Mobility. Elimination of unsightly cables. Problem Identification: Task 2 10 Marks Investigate the Internet connection requirements for the Fire Department. a) Describe the Internet services that may be required. b) Explain the connection speeds that are suitable for these requirements. c) Find examples of Internet Service Providers (ISPs) that can meet these requirements in your country. d) Make a recommendation to use one ISP based upon the services offered and price charged. Solution of Task 2 a) Hardware and Software Requirements: Computer with either: Windows 95, Windows 98, Windows ME, Windows XP Professional, Windows NT 4.0, Windows 2000, or Windows Server 2003 installed. A CD-ROM drive for the installation compact disc. Adequate disk space for the database, business objects, and Web pages 10 MB free space minimum. Transmission Control Protocol/Internet Protocol installed. A network adapter card and local area network connection. An Internet connection and Internet Protocol address from your Internet Service Provider. Network Adapter board. Figure 2.1: Intranet network system b) Connection speeds requirements: 512 for upload is standard connection for sound only, the much required is 138 kbps, means that 512 138 = 374 kbps free for chat or image. Usually, download > upload is possible for internet provider to have busy server and in this situation you will be connected from phone standard line, with smaller speed. So in this system it demands 512 kbps connection speed. c) Examples of Internet Service Providers in our country: Brack net. Zip. Qubee. Grameen phone Internet. Bangla lion. Recommendation to use the ISP : In this system we select Qubee as out ISP because, Qubee has the solution which is fast and reliable. Very much cost effective. More then it is driven by WI-MAX technology.   And obviously it is portable.

As a minimum include the following information: a) How each method works (frequencies, full/half duplex, etc). b) Details of the legal requirements for operating the system in your country. c) Costs of setting up and operating the system, including licensing costs, equipment costs, etc. d) Limitations of each method. Provide a recommendation for how voice communications should be set up and run including reasons for this recommendation. Solution of Task 3 Method of full/half duplex system: Half-Duplex: A  half-duplex  system provides for communication in both directions, but only one direction at a time. Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying. An example of a half-duplex system is a two-party system such as a walkie-talkie style two-way radio, wherein one must use Over or another previously designated command to indicate the end of transmission, and ensure that only one party transmits at a time, because both parties transmit on the same frequency. A good analogy for a half-duplex system would be a one lane road with traffic controllers at each end. Traffic can flow in both directions, but only one direction at a time with this being regulated by the traffic controllers. Full-Duplex: A  full-duplex  system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex since they allow both callers to speak and be heard at the same time. A good analogy for a  full-duplex  system would be a two-lane road with one lane for each direction. Examples:  Telephone,  Mobile Phone, etc. Two way radios can be, for instance, designed as full-duplex systems, which transmit on one frequency and receive on a different frequency. This is also called frequency-division duplex. Frequency-division-duplex systems can be extended to farther distances using pairs of simple repeater stations, owing to the fact that the communications transmitted on any one frequency always travel in the same direction. Full-duplex Ethernet connections work by making simultaneous use of all four physical pairs of twisted cable, where two pairs are used for receiving packets and two pairs are used for sending packets, to a directly connected device. This effectively makes the cable itself a collision-free environment and theoretically doubles the maximum bandwidth that can be supported by the connection. There are several benefits to using full duplex over half duplex. First, time is not wasted since no frames need to be retransmitted as there are no collisions. Secondly, full bandwidth is available in both directions because send and receive functions are separated. Third, stations/node do not have to wait until other operations complete their transmission as there is only one transmitter for each twisted pair. Legal requirements for operating the system in our country: 1.1 As per the national frequency allocation plan 2005 (nfap 2005), spectrum from the ism band in 2.4000-2.4835 ghz and 5.725-5.875 ghz is allocated for wi-fi use. 1.2.  Ã‚  Ã‚   Access to the spectrum will be on shared basis. There will be no exclusive assignment to any individual or organizations, whether for private, public or commercial use. 1.3.  Ã‚  Ã‚   Any government or private organization/educational institution/corporate body can establish and use wi-fi network on non commercial/non-profit basis. 1.4.  Ã‚  Ã‚   Household/private users are not required to take any permission from the commission or pay any levy/charge for using wi-fi in the given ism band. 1.5.  Ã‚  Ã‚   Both indoor and outdoor wi-fi is permitted in the given spectrum of ism band. However, the maximum power output for the wi-fi equipment is limited to 1 watt. 1.6.  Ã‚  Ã‚   All commercial wi-fi hotspot operators/service providers shall possess an isp or equivalent license (e.g., bwa license). Existing operators having such license from the commission will be eligible to establish wi-fi network for providing last mile solution. 1.7.  Ã‚  Ã‚   Operators/service providers will submit a detailed list of wi-fi outdoor hotspots to the commission.

It is really not correct to say that the waves collide or hit, although this is often how such an interaction is termed. When the  crest  of one wave passes through, or is  super positioned  upon, the  crest  of another wave, we say that the waves  constructively interfere. Constructive interference also occurs when the  trough  of one wave is super positioned upon the  trough  of another wave. During any wave interference the shape of the medium is determined by the sum of the separate amplitudes of each wave. We often say that when waves interfere, amplitudes add. Using the arrow buttons step through the above animation to see how the amplitudes add during constructive interference. Notice that in this animation the crest of the red wave constructively interferes with the crest of the blue wave. Recommendation for voice communications set up: Wireless Fidelity, better known as Wi-Fi, is a term used to describe the underlying technology of wireless local area networks based on the Institute of Electrical and Electronics Engineers 802.11 standards. Initially intended to connect mobile computing devices in local area networks, Wi-Fi applications have grown to include various data, voice, and video services such as Internet access and Voice over Internet Protocol. Wi-Fi technology platform is based on single-carrier direct-sequence spread spectrum and multi-carrier Orthogonal Frequency Division Multiplexing radio technologies to transmit and receive signals. Wi-Fi is more commonly used in point-to-multipoint environments to allow extended network connectivity of multiple portable devices such as laptops, telephones, or PDAs. Wi-Fi also allows connectivity in point-to-point mode, which enables devices to directly connect and communicate to each other. A region covered by one or more APs is considered a hotspot. Home networks commonly deploy one AP that is typically connected directly to an Internet service provider , whereas larger networks may require at least several APs positioned in strategic locations to provide flexibility of service to a large number of users. Because of range constraints, Wi-Fi networks are used in localized regions. Figure 3.1: Common Wi-Fi Network Wi-Fi can be used in conjunction with other emerging wireless technologies, such as Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Mesh Networking, to extend the coverage area of terrestrial networks and to provide high-speed mobile data and telecommunications services. For example, WiMAX can be used as a backhaul technology to connect multiple Wi-Fi hotspots with each other and to other parts of the Internet. WiMAX describes the technology behind wireless networks based on the IEEE 802.16 standards. Wi-Fi technology has been highly utilized for many applications such as voice communications, video communications, and various data services. This section describes how Wi-Fi technology supports these applications. The expansion of telecommunications has spawned great need for new technologies to provide sought-after voice communication services. Internet telephony, better known as VoIP, is a technology that allows for transport of voice traffic using an Internet Protocol (IP) network infrastructure. VoIP and Internet telephony have come a long way since their inception, and with the impressive development of Wi-Fi technologies, the popularity of voice communications over wireless will continue to increase. Common VoIP networks consist of the hardware and software enabling the end users to leverage the Internet as the transmission medium for telephone calls. IEEE 802.11 Voice over Wi-Fi is the wireless version of this technology that is designed to work with wireless devices. VoWi-Fi solutions provide mobile users during critical missions with the ability to roam wirelessly. Typically, a VoWi-Fi user device will connect to an AP to authenticate to a designated VoIP network. Once associated to an AP and authenticated to the appropriate network, a user will have the capability of mobile voice communications across enterprise networks, residential broadband networks, or even public/private hotspots. VoWi-Fi products are becoming more advanced and readily available to support various challenging short- and long-term voice service needs, such as in commercial, healthcare, private, and incident site environments. Given the steadily increasing demand for voice services and mobility, wired and wireless VoIP deployments continue to grow and eventually will become more prevalent than traditional circuit switching voice systems. One advantage VoWi-Fi provides over traditional circuit-based voice communications is an ability to easily accommodate user growth in many different operating environments, through software configuration. Typically, physical attributes of circuit-switched voice systems can limit the flexibility of real-time configuration. Deploying a wireless VoIP system can provide significant savings in cost and deployment time when compared with other wireless voice communication solutions.

Solar Power Essay -- Alternative Energy Clean Photovoltaic Cells Panel

Solar Power: An Alternative Energy Source Since first discovered in the 1860s, the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells, the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses, but is still too expensive and risky for many residents. Researchers are still making advances to solar technology for it to be a feasible energy source in the future. Solar energy was first started in the 1860s when Auguste Mouchout and William Adams found a way for storing solar radiation into tanks of water. Since then, there have been improvements to the processing of solar energy, which has been split into two categories: agricultural based and electricity based. The agricultural method, otherwise known as thermal solar energy, uses the sunlight to heat liquid and power steam engines. Solar collectors can be used on houses or business buildings to store the energy. Different types of solar collectors are flat-plate collectors, evacuated tube collectors and integral collector storage systems (US Department of Energy, 2007, para. 2). The electrochemical process is more complicated and requires photovoltaic (PV) cells to capture the solar energy and convert it into electricity. PV cells have many uses, including powering batteries or mechanical devices by absorbing the photons and creating a voltage.
