Is A Smartphone A - 2206 Words

Today a smartphone is part of almost every person’s life. It’s used to assist us in just about anything, whether we need directions, need to text a friend, or even buy a ticket to a movie or theme park we can perform tasks like this in just a matter of minutes. So what is a smartphone? A smartphone is a phone which includes a state-of-the-art mobile operating system that incorporates the features of a personal computer operating system with other features useful for mobile or handheld use. Typically, these features combine the usual use of a cell phone with those of other popular mobile devices, such as personal digital assistant, media player and GPS navigation unit. Almost all smartphones can access the Internet, have a touchscreen user†¦show more content†¦This mobile phone was the first phone to incorporate PDA (personal digital assistant) features, which was demonstrated that year at the COMDEX computer industry trade show. In addition to the PDA features, the phone also included visionary apps such as maps, stocks and news. Soon after the release of the prototype, a refined version was introduced to consumers, the Simon Personal Communicator. The Simon Personal Communicator first revealed its face in 1992 and was the first cellular device that can be properly referred to as a â€Å"smartphone† even though it was not called that when it was initially released. Simon came with a monochrome touchscreen, a stylus, and a charging base station. It went on sale in 1993 through BellSouth Cellular for an enormous price of $899 with a two-year agreement or $1,099 without contract. IBM sold approximately 50,000 Simon units. Nokia entered the not-yet-developed smartphone space in 1996. It released the Nokia 9000 Communicator to the market, a 1.5-inch thick, 14 ounce phone with an outward facing dial pad, navigation keys, and monochromatic display. Unlike the Simon Personal Communicator, the 9000 Communicator looked almost like a run-of-the-mill cell phone from 1996. However, along the left edge, was a hinge which opened to a full QWERTY keyboard and physical navigation buttons neighboring a much larger display. The Nokia 9000 Communicator, like the Simon, was also not called a â€Å"smartphone† even though it was capable of email, fax, Web

War And Its Consequences The True Reality - 1545 Words

War and its Consequences: The True Reality American veteran and novelist, Kurt Vonnegut uses his wartime experiences as a basis for his thought-provoking, antiwar novel, Slaughterhouse-Five. The novel follows Billy Pilgrim, an American chaplain’s assistant who serves near the end of World War II, through the horrific fire bombings of Dresden and his life after the war. In his novel, Vonnegut presents twentieth century war as traumatic and destructive, however; it is something that cannot be avoided so humans need to develop a means to cope with its effects. Vonnegut uses several techniques to reinforce his main argument, which states that twentieth century war is traumatic and destructive however it cannot be prevented. Throughout the†¦show more content†¦Contrary to Mary’s concerns, Vonnegut makes it explicitly clear that war is neither â€Å"glamorous† nor â€Å"wonderful† from the moment the protagonist, Billy Pilgrim is deployed. Upon arrival in Germany, Pilgrim is â€Å"never even is sued a steel helmet and combat boots† and after being trapped behind enemy lines he is left â€Å"empty-handed, bleakly ready for death†. These passages illustrate how the war devastates the American army to the extent that the soldiers are not properly equipped. As the novel continues, German soldiers capture Billy Pilgrim and another soldier Billy has been wandering with, Roland Weary. Now the reader is then exposed to the desolate reality of who is truly fighting. The soldiers are the exact opposite of what Mary described: â€Å"two of the Germans were boys in their early teens. Two were ramshackle old men, droolers as toothless as carp†. Vonnegut demonstrates that the soldiers remaining are weak and either far too young or too old to be fighting. In this section of his novel, Vonnegut illustrates that a considerable number of young men from an entire generation are no longer able to fight as a result of injury, death or capture. By demonstrating to the rea der the truth of who is actually fighting, Vonnegut is illustrating the true destruction that war causes. Following their own capture, Roland Weary and Billy Pilgrim become prisoners of war and are subjected to the ill treatment and poor

Socioeconomic Status Ses Health And Social Care Essay Free Essays

Socioeconomic position ( SES ) has been studied and proven to hold a direct consequence on general wellness and well-being but what consequence does SES hold on mental wellness? The effects of SES on mental wellness results were outlined in subdivisions of a survey called Socioeconomic Status and Health: The Challenge of the Gradient ( SESSH ) . The SESSH survey states â€Å" Persons higher in the societal hierarchy typically enjoy better wellness than do those below ( Alder et. al 1994 ) , this includes mental wellness and it ‘s all of its related diseases. We will write a custom essay sample on Socioeconomic Status Ses Health And Social Care Essay or any similar topic only for you Order Now Several other surveies such as the Childhood Socioeconomic Status Is Associated with Psychosocial Resources in African Americans: The Pittsburgh Healthy Heart Project ( Beatty et. al 2011 ) , conducted by the University of Pittsburg aid to confirm the findings from the SESSH survey done several old ages before. One of the major effects of lower SES position on mental wellness is the deficiency of entree to mental wellness attention. Whether urban or rural the hapless have more trouble in deriving entree to decently trained medical forces and installations to cover with the jobs sing the mental wellness ( Grembowski et. al 2002 ) . The paper, Rural Communities Suffer Poor Mental Health Care ( Association of Schools of Public Health 1974 ) highlights some of the issues unique to the rural hapless in America and the mental wellness issues that surround the community. The current research shows that SES plays a major function in the mental wellness of patients. Major emphasis factors from the effects of lower SES get down to take its toll on the mental wellness of persons populating in high poorness countries ( Leventhal et. al 2003 ) . In the survey Socioeconomic Status and Health: The Challenge of the Gradient it states the â€Å" Socioeconomic position is related to both major depression and depressive symptoms † ( Alder et. al 1994 ) and to an addition of ill will and anti-social activity and suicidal behaviours. ( Alder et. al 1994 ) . SES besides leads to an addition in psychological emphasis that can finally trip greater perceptual experiences of emphasis and negative emotion. These perceptual experiences are known to change neuroendocrine response and assorted other physiological alterations ( Alder et. al 1994 ) . The deficiency of entree to proper mental wellness attention is a major factor in the long term wellness results of tho se in lower SES groups ( Grembowski et. al 2002 ) . Further back uping the survey Socioeconomic Status and Health: The Challenge of the Gradient, the survey Childhood Socioeconomic Status Is Associated with Psychosocial Resources in African Americans, shows that SES is non merely a factor in finding mental wellness but besides has an consequence on the ability to entree the household and community support in early childhood might hold played a possible mitigating factor ( Beatty et. al 2011 ) . The survey shows, that in African American topics, the intercession of positive household and community involvement early in childhood could positively impact subsequently psychological wellness but that lower SES general prohibits the positive household and community support demand to antagonize the degrees of emphasis and hapless self-perception in lower SES persons ( Beatty et. al 2011 ) . The article, Traveling to Opportunity: an Experimental Study of Neighborhood Effects on Mental Health, farther address the thoughts that community and poo rness, cardinal facets of SES, have on mental wellness results ( Leventhal et. al 2003 ) . Families that moved from lower SES position vicinities to higher 1s had a lessening in the presence and badness of depression and other psychological issues ( Leventhal et. al 2003 ) . The articles, through the usage of studies and long term patient surveies, are able to demo the direct effects of lower SES on psychological wellness. The information shows that long term exposure to the emphasis of lower SES leads to several types of psychological upset including depression, feelings of lower dignity and assorted other clinical issues including terrible alcohol addiction and drug dependence ( Alder et. al 1994 ) . The surveies did an first-class occupation of showcasing the issues affect lower SES groups but could hold been more convincing in their methodological analysiss. The information from the research validates the fact of lower SES straight affect psychological wellness but fail to take into history several variables which would let for incredulity. Each of the articles fails to turn to whether the psychological issues are straight linked to lower SES from the deficiency of instruction of approximately positive life style picks and deficiency of instruction a bout entree to wellness attention, is the higher incidents of mental unwellness merely because the hapless have less instruction on healthy life styles and how to seek intervention. The consequences could be strengthened by utilizing greater cross subdivisions of the lower SES communities, over longer periods of clip and supplying basic instruction on how to entree intervention to see if mental wellness issues are genuinely related to SES or if there are other factors that contribute. With the exclusion of Traveling to Opportunity: an Experimental Study of Neighborhood Effects on Mental Health, none of the surveies attempted to see if the conditions were reversible by taking the topics form the lower SES environment. If remotion of the topic from the environment produces clear positive consequences in a big survey group you could more easy find that SES is a clear factor in the patients ‘ wellness.

Deployment and Operations Committee †Free Samples to Students

Question: Discuss about the Deployment and Operations Committee. Answer: Introduction: The best interface for a system is no user interface, this theory has been a recent craze among the software or application developers. This concept circumvents the fact that the utility of an application can be improved even without the implementation of an interface. There are numerous examples that prove the validity of the statement mentioned above. One of the examples is as provided below (Johnson, 2013). In recent years, several car companies have developed applications for smart phones that facilitate the consumers of their car to unlock the doors of the cars remotely (Barga, Fontama Tok, 2015). The unlocking procedure follows the following steps: The following procedure lets the driver to open the car door and enter the car using a Smartphone latest application that involves 13 steps to complete. The application compels the driver to use the phone. The driver even must take the pain to learn a new interface and all its functionalities (Paparo Martin-Delgado, 2012). Moreover, the experience is designed around the flow of the computer, instead of the flow of a person. However, it can be arranged that eliminating the UI from the above-mentioned process reduce the complete procedure to only three steps: The simplicity can be achieved by many processes, which is possible without the involvement of any user interface. Sophisticated technologies like motion sensors, proximity sensors and biometric plates can be used for achieving this objective. Proximity sensor integrated to the locking mechanism of a car can detect the presence of the registered driver within a specified range around the car and unlock the door automatically. The door lock of the car can also be equipped with biometric sensors that only open when the registered fingerprint of the driver is placed on it (Paparo Martin-Delgado, 2012). The process shown in Figure 2 reduces the complexity of the steps in Figure 1 yet improves the experience of the driver. All of this is achieved without the use of any UI. Therefore, the validity of the statement is thus proved by the example. Applications without UI have a variety of utility in todays world ranging from domestic to organisation. One of the remarkable utility of such application can be found for the daily works of the visually disabled people. These types of applications help the blind people to perform various digital functions through gesture and voice processes like making calls, composing and sending mails, receiving or reading mails, listening to music, browsing the web and such (Paparo Martin-Delgado, 2012). To accomplish an application without UI, it is required to integrate an application with sophisticated Artificial Intelligence (AI).Recent examples of AI integrated smart applications are Magic, Operator, M by Facebook, Cortana by Microsoft and Google Now or Google Assistant by Google. These applications provide almost unlimited option to perform digital functions without involving any UI (Paparo Martin-Delgado, 2012). The specifications of three types of twisted pair cables are as given below: CAT 5e 100 MHz UTP is used for 100 Mbps through 1Gbps Ethernet 1 100 m LAN applications. CAT 6 250 MHz UTP cable supports 10 Gbps short length applications from 35 55 m, which depends on crosstalk environment. CAT 7 600 MHz is an individually STP cabling used for 10 Gbps 100 m Ethernet LAN applications with better control performance in crosstalk than the CAT 6a type (Wessemann et al., 2015). The specifications of three types of coaxial cables are as given below: RG 6/UQ is a quad shield variant of RG 6 that has four layers of shielding. It has an impedance of 75 ohms. RG 7 loses less data at higher frequency for cables used in television, satellite and modems. It has an impedance of 75 ohms. RG 8/U is used in amateur radio. The Thicknet is similar (10BASE5). It has an impedance of 50 ohms (Nordebo et al., 2013). The specifications of three types of fibre optic cables are as given below: The composition of a multimode fibre optic cable consists of a core of large diameter. It has multiple pathways of light medium. It is generally available in two core sizes that is, 50 and 62.5 microns respectively. It is used in general information and applications related to voice fibre such as attaching segments to a network whose utility is in existence, and in applications that are small developments like alarm systems. LED or laser light medium is used by multimode cable core of both size (Agrawal, 2012). The core of a single mode cable is made of glass and its size ranges between 8 10 microns. The size of the core is small compared to that found in the multimode cable. It has a mono light pathway. The range of a single mode fibre optic cable is 50 times more than the multimode cable. It is generally applied in applications that requires high bandwidth range for its operation and in strong network connections that is spread over a wide range of area (Agrawal, 2012). Laser optimised 10 Gb fibre optic cable is a multimode cable variant that has marked fibre optic cable of refractive index profile in each assembly. Its utility is in premise networking applications that include large bandwidth (Agrawal, 2012). The following table shows the comparison between Video Tracking, Sensors used in Internet of Things (IoT) and RFID in relevance to their respective advantages and disadvantages (Xia et al., 2012). Advantages Disadvantages Uses Video Tracking Technology Helps to maintain visual records Aids in providing video evidence against criminal activities Easy to compromise High expenditure in installing Causes privacy issues for general people Video Tracking finds its utility in domestic as well as organisations for the purpose of security. Temperature Sensors It is very sensitive Cost of installation is less It can be surface mounted Accuracy is high Heats up on its own automatically Fails to detect moisture The utility of a temperature sensor is generally found in thermostat devices or semiconductors of high sensitivity. Pressure Sensors Requires less cost to implement Has the capability to adapt to various applications Has high output of signal level Uses robust technology The sensor is highly sensitive to vibrations Moving objects are difficult to detect These sensors are generally used in devices that uses a touch enabled screen Proximity Sensors Has the ability to remain functional in adverse weather conditions Have high accuracy rate Switching rate is high Has limited range of operation Is limited to detect targets of metallic composition The retail industry uses these sensors to track the customers in a chosen proximity and transmit offers in mobile phones. Optical Sensors Has immunity towards electromagnetic interference or noise Has a wider coverage area Very portable to carry and use Has immunity towards heat and chemical reaction Has high sensitivity Provides complete electrical resistance from high voltage electrical sources Sustains loss due to coupler Suffers loss due to scattering and absorption Suffers Impurity, Insertion and Reflection loss Receives interference due to multiple effects Is utilised in IoT technologies, aerospace, healthcare, chemical and energy platforms RFID Is capable of storing information A consumer can be tracked with the RFID tag integrated with the purchased device Versatile technology RFID implementation is very expensive Development of the program requires sufficient time External electromagnetic interference affects the scanning range of an RFID reader Has a very limited range of 3 meters Causes privacy issues Has a vast utility in retail and other organisational sectors as well as in educational institutions Table 2: Advantages, Disadvantages and Uses of Video Tracking Technology, Sensors of IoT and RFID Technology (Source: (Xia et al., 2012)) The various threats to security in association with the implementation of Internet of Things Technology that can be violated to harm consumers are as follows: Creating safety issues Enabling unauthorised access and use of personal data of consumer Allowing to carry out attacks on other systems Nevertheless, other security issues can be addressed in relevance to the implementation of IoT technologies such as direct gathering of important personal data such as bank account details, location, health information and other such information regarding a user (Kumar Patel, 2014). This paradigm enables a unidirectional communication from a single publisher to multiple subscribers. A subscriber expresses its interest towards a specific category or class of data to the publisher, which the publisher acknowledges and transmits the same to the interested subscriber whenever available. According to Nielsen who formulated the Law of Internet Bandwidth, the internet connection speed of a heavy user of internet increases by fifty percent per annum (Zhao et al., 2013). Moore analysed the statistics of growth of transistors in his time and postulated that the quantity of transistors per square inch on integrated circuits will double per annum starting from the year of its invention (Zhao et al., 2013). Both the laws of Nielsen and Moore postulated laws related to technologies that have Internet of Things Platform (Zhao et al., 2013). References Agrawal, G. P. (2012).
