Survey of Wireless Computing School Of Computer Science Florida International University Abstract Wireless technology can provide many benefits to computing including faster response to queries, reduced time spent on paperwork, increased online time for users, just-in-time and real time control, tighter communications between clients and hosts. Wireless Computing is governed by two general forces: Technology, which provides a set of basic building blocks and User Applications, which determine a set of operations that must be carried out efficiently on demand. This paper summarizes technological changes that are underway and describes their impact on wireless computing development and implementation. It also describes the applications that influence the development and implementation of wireless computing and shows what current systems offer. 1 Introduction Wireless computing is the topic of much conversation today. The concept has been around f or some time now but has been mainly utilizing communication protocols that exist for voice based communication. It is not intended to replace wired data communication but instead to be utilized in areas that it would be otherwise impossible to communicate using wires. Only recently has the industry been taking steps to formulate a standard that is more suitable to data transmission. Some the problems to be overcome are: (1) Data Integrity - relatively error free transmission, (2) Speed - as close as possible to the speed of current wired networks, (3) Protection - making sure that the data now airborne is encoded and cannot be tapped by unwelcome receivers, (4) Compatibility - ensuring that the many protocols that sure to be created subscribe to a standard to allow inter-operability, (5) Environmentally safe - strengths of electromagnetic radiation must be kept within normal levels. In our study of the theories and implementation concerns of wireless computing, we found that it is being treated in an object oriented fashion. Scientists and development crews, including the IEEE, are doing their best to implement wireless connectivity without changing the existing computer hardware. As a result, a lot of focus is on using existing computer hardware and software to convert data to a format compatible with the new hardware which will be added to the computer using ports or PCMCIA connections that already exist. This means that wireless communication will be transparent to the user if and when wireless computing is utilized on a wide scale. Wireless computing applications covers three broad areas of computing today. Replacement of normal wired LAN's need to retain the speed and reliability found in wired LAN's. Creation of semipermanent LAN's for quick and easy setup without the need for running wires. This would be necessary for events such as earthquakes. The last category is that of mobile computing. With advent of PCMCIA cards, notebook computers are being substituted for regular desktop machines with complete connectivity of the desktop machine. However, you lose the connectivity when out of the office unless you have a wireless means of communicating. On the compatibility issue, the ability to mix wireless brands on a single network is not likely to come soon. The IEEE Standards Committee is working on a wireless LAN standard -- 802.11, which is an extension of the Ethernet protocol. Because the field of wireless communication is so broad, the IEEE was not able to set a standard by the time private researchers were ready to test their theories hoping to set the standard for others to follow. 2 Methods There are a few methods of wireless communication being theorized and tested. (1) Radio: This is the method that makes use of standard radio waves in the 902 MHz to 928 MHz frequency range. Although these frequencies are well used, methods have been developed to ensure data integrity. Spread spectrum transmission of data is a met hod where the transmitter will send information simultaneously out over many frequencies in the range increasing the change that all data will eventually reach the receiver. Frequency hopping is an additional measure that also enables data security. The 26 MHz range of frequencies is further divided in to channels. The transmitter then sends out data hopping from one channel to the next in a certain pattern known to the receiver. Within each channel, spread spectrum transmission can be used to maintain interference

Human Behavior Essay Example | Topics and Well Written Essays - 500 words

Human Behavior - Essay Example Nonetheless, the several States possess several rules as well as regulations, due to the fear of being litigated, that teenagers give up on their prospects for their personal explorations. Thus, pools can be enclosed so that it does not issue the impression of an ‘attractive nuisance.’ Most individuals within the given area do not possess pools; however, even the streams frequented do not have symbols to mention ‘Jump at your risk,’ since it is obvious. However, why would someone decide on jumping unless they are ready to face the consequences? Accountability within the nations appears to have been considered from the individuals acting as well as placed upon the possessor of the given land; hence, making most citizens want to blame somebody else as much as possible (Peters-Golden, 2012). The author also mentions he was capable of growing up, play creatively, as well as able to explore the outdoors as well as nature freely, with the requisite element of risk ; yet, well succeeded, that is currently lacking from the typical risk-averse American childhood. Hence, the need for such police as well as laws in addition to the moral mandates to be nice to an unfamiliar person does not arise within tiny cultures, in which every individual knows everybody else.Conversely, getting to learn about a diverse group of different cultures that appear to be unique on their own. Thus, it is a relief to learn that every culture tends to possess distinctive patterns as well as practices

Summary - Article Example Humor and laughter are closely related however these are not synonymous. One can laugh without a humorous stimulus and similarly one can experience humor without laughter. Historically humor history is perceived to be 35000 years old. Almost every culture spends appreciable time communicating in a humorous context. No single humor theory is universally accepted however, three essential themes, are repeatedly observed in the majority of humor theories: 1) humor reflects a set of incongruous conceptualizations, 2) humor involves repressed sexual or aggressive feelings, and 3) humor elevates social status by demonstrating superiority or saving face. It has been discussed that animals also show response to humorous behavior. With respect to genetics, it has been observed that women laugh 126% more than men during conversations with each other. Brain damage, particularly in the frontal lobes, causes deficits of humor appreciation. The elucidation of the neurobiology of humor has benefited from two approaches: 1) observing the effects of various brain lesions on humor perception and 2) functional magnetic resonance imaging (fMRI) studies, which monitor brain activity in normal subjects while perceiving humor. Despite language and cultural barriers, humor in traditional societies is generally comprehensible to visiting anthropologists. Two humor phenomena especially standout in the anthropological literature: joking relationships and clowns. There is no way to know with certainty when humor evolved relative to language although it would appear that at least sophisticated humor must have succeeded language. The credible range for the origins of language lands between a few hundred thousand years to about 2-4 million years ago. There is increasing evidence that a new level of symbolic thought was achieved around 50,000 years ago. A figurine integrating the head of a lion with the legs of a person dated around 32,000 years old is among the earliest evidence for symbolic art. Humor can perhaps be framed as an incongruent social concept â€Å"violating† the essence of a congruent social concept. Dunbar (1993) has put forward a theory that, in primates, neocortical size is proportional to group size and that language ultimately replaced grooming as the primary social bond .Humor is a fascinating cognitive function. The relative ease in how we use it belies its considerable complexity. To conclude humor appears to be a function of Homo sapiens’ augmented social abilities and as an extension of language, could perhaps be the most complex cognitive function in the animal kingdom. The origins of language, spirituality, hominid group size and animal teasing may have particular relevance to humor. A number of humankind’s higher cognitive functions could well be inextricably rooted in humor’s evolutionary history, thus making this subject worthy of further exploration.

Explorations of Childhood and Duty in “The Chimney Sweeper” and “Casab

Although Blake wrote â€Å"The Chimney Sweeper† featured in Songs of Innocence before Felicia Hemans was ever born, issues relevant to first-generation Romantic authors still pervaded the literary scene when second-generation authors like Hemans finally took the stage. â€Å"Casabianca,† published in 1826, and â€Å"The Chimney Sweeper,† published in 1789, both address a central question: What does it mean to be a child? Both poems examine the duties that children have to society as a whole. While there is an overriding sense of an allegiance to duty in both poems, the poems’ situational irony complicates the relationship between children and responsibility. The final line of â€Å"The Chimney Sweeper† best demonstrates this complicated relationship. The speaker of â€Å"The Chimney Sweeper† concludes by saying, â€Å"So if all do their duty they need not fear harm† (24). However, we as readers have reason to question the validit y of the speaker’s promise since the poem seems to suggest that relief from hardship only comes through death. Through their language, choice of perspective, situational irony, and other features, â€Å"The Chimney Sweeper† and â€Å"Casabianca† grapple with the notion of childhood in order to clarify the complicated relationship between children and duty in society. The poems’ structures appeal to the youth around whom they centered. Each poem has end-rhyming quatrains, which create a nursery rhymesque feel. Both poems have a more or less regular rhythm, which adds to the happy feeling created by the rhyme. However, it is a common occurrence for the heavy content to contrast with the poems’ structure. In order to better understand both poems, it is important to examine why the authors would have chosen to use a structure that contr... ... fair to say that both poems are proponents of both duty and childhood because of their youthful structure and irony. However, each poem is more heavily weighted towards one allegiance or another. Hemans does show remorse for Casabianca’s untimely death, but her choice to present the story from the third person perspective proves that her allegiance is more towards the fulfillment of duty to family and country than the fulfillment of childhood. On the contrary, Blake’s choice to give his child character a first person voice empowers his protagonist and supports the idea that Blake was a bigger proponent of childhood than of duty. Both poems reveal the complicated nature of this issue during the Romantic period, and each poem counters the other to give them both a more multidimensional perspective on the consequences and benefits of preserving childhood and duty.

Interview with a human resource manager Essay

Many organizations build human resource management section separately so that an expert service is provided to the people and the human resource function performed efficiently. These organizations consider people as their most priceless assets and so they need managers in this section who are efficient, responsible and devoted to the rules and regulations of the respective organization. For this they need a capable person who can cover up the responsibilities excellently and help in further development of the organization. Different organizations have varied expectations from the candidate and the ecruitment is done according to the requirements of the company. It depends upon the size of the company, the physical nature of the products, the size of the staff members, its functions, aims and complexities that decide what exactly is expected from a human resource department. A human resource manager has to keep a balance between the employer and the employees. He has to act as an advocate for both, the organization and the people who work for it. Only one or two decades ago the human resource manager was associated with personnel and administrative division of the company and mostly confined to some aper work. They had to deal with hiring of the employees for different sections of the company, paying them and dealing mostly with their benefits. But today most of the organizations are customer centered and are becoming more adaptable to changes needed for successful marketing strategy. So the responsibilities of today’s human resource manager is to take care of customer satisfaction and make specific changes considering success in marketing along with taking care of the benefits of the employees, payroll and do some paper work as well. The HR manager has to be very attentive and cautious with ny and every change that is taking place in the marketing policy. With the globalization of small and big businesses, it seems that the development of an organization depends quite a lot on the human resource manager and so he is answerable to almost every aspect of marketing and customer satisfaction section. This includes a lot of work pressure, which burdens the professionals a lot. Almost every human resource manager is suffering form this problem and feels the pressure from various directions. They have to discuss the matters and the targets need to be achieved in imited time and above all be updated with the latest in marketing strategy. Those who are interested in regular competition and want to progress fast can try and make human resource manager a career but I feel that with so much of work pressure a man will have to sacrifice a lot in life just to satisfy his ego and earn success and new heights in monetary section. With flexible working hours the manager has to sacrifice various aspects of recreation and relaxation with family and friends. With stress and conflicts in the organization, the human resource manager needs to take care of it before it does any harm to the organization. He needs to be like a team leader and convince the employees with the views of the management and vice versa. Open communication and discussion helps a lot and the manager balances if there is any aggressive attitude in the employees. The only thing that I work out from the interview with a human resource manager is that the job satisfies people who are very ambitious and enthusiastic. It is not that the job or its responsibilities are not reachable. Some managers find it very challenging and like to work in a competitive environment so that the charm of life and work remains there for them.
