Modern gadgets Essay Symbian OS is designed for the mobile phone environment. It addresses constraints of mobile phones by providing a framework to handle low memory situations, a power management model, and a rich software layer implementing industry standards for communications, telephony and data rendering. Even with these abundant features, Symbian OS puts no constraints on the integration of other peripheral hardware. This flexibility allows handset manufacturers to pursue innovative and original designs. Symbian OS is proven on several platforms. It started life as the operating system for the Psion series of consumer PDA products (including Series 5mx, Revo and netBook), and various adaptations by Diamond, Oregon Scientific and Ericsson. The first dedicated mobile phone incorporating Symbian OS was the Ericsson R380 Smartphone, which incorporated a flip-open keypad to reveal a touch screen display and several connected applications. Most recently available is the Nokia 9210Communicator, a mobile phone that has a QWERTY keyboard and color display, and is fully open to third-party applications written in Java or C++. The five key points small mobile devices, mass-market, intermittent wireless connectivity, diversity of products and an open platform for independent software developers are the premises on which Symbian OS was designed and developed.

Symbian OS has a POSIX-compliant interface and a Sun-approved JVM, and the company is actively working with emerging standards, such as J2ME, Bluetooth, MMS, SyncML, IPv6 and WCDMA. As well as its own developer support organization, books, papers and courses, Symbian delivers a global network of third-party competency and training centers the Symbian Competence Centers and Symbian Training Centers. These are specifically directed at enabling other organizations and developers to take part in this new economy. Symbian has announced and implemented a strategy that will see Symbian OS running on many advanced open mobile phones. Small devices come in many shapes and sizes, each addressing distinct target markets that have different requirements. The market segment we are interested in is that of the mobile phone. The primary requirement of this market segment is that all products are great phones. This segment spans voice-centric phones with information capability to information-centric devices with voice capability. These advanced mobile phones integrate fully-featured personal digital assistant (PDA) capabilities with those of a traditional mobile phone in a single unit. There are several critical factors for the need of operating systems in this market. It is important to look at the mobile phone market in isolation. It has specific needs that make it unlike markets for PCs or fixed domestic appliances. Scaling down a PC operating system, or bolting communication capabilities onto a small and basic operating system, results in too many fundamental compromises. Symbian believes that the mobile phone market has five key characteristics that make it unique, and result in the need for a specifically designed operating system: 1) mobile phones are both small and mobile. 2) mobile phones are ubiquitous they target a mass-market of consumer, enterprise and professional users. 3) mobile phones are occasionally connected they can be used when connected to the wireless phone network, locally to other devices, or on their own. 4) manufacturers need to differentiate their products in order to innovate and compete in a fast-evolving market. ards.

greek orthodox Essay -- essays research papers

The Greek Orthodox Church is one of the three major branches of Christianity, which "stands in today's society as one of the communities created by the apostles of Jesus in the region of the eastern Mediterranean, and which spread by missionary activity throughout Eastern Europe" .The word orthodox comes from Greek, this means right-believing. Currently, the orthodox religion has more than 174 million followers throughout the world. The Greek Orthodox church is autocephalous, which means governed by its own head bishop. The head bishops of this autocephalous church may be called patriarch, metropolitan, or archbishop. These clergymen are much like the Pope; they decide church doctrine and generally make important decisions on controversial topics. In its doctrine statements, "the Greek Orthodox church strongly affirms that it holds the original Christian faith, which was common to East and West during the first millennium of Christian history" (Meyendorff 18). More particularly, it recognizes the authority of the ecumenical councils at which East and West were represented together. These were the councils of Nicaea I (325), Constantinople (381), Ephesus(431), Chalcedon(451), Constantinople II (553), Constantinople III (680), and Nicaea II (787) (Encarta 1996). The power of teaching and guiding the community is bestowed on certain ministries, particularly that of the bishop of each diocese or is directed through certain institutions, such as councils...

Lighting Needs of Houses in Newbold Crossing

LIGHTING NEEDS OF THE HOUSE Glare problems; snow or bare ground Newbold is situated in the rural north-west sector of NSW, with Clarence River been the main body of water that passes directly through the area. According to results conducted by the Department of the Environment, Water, Heritage and the Arts  (2009) the turbidity of this large body of water appears to be fair to poor. Turbidity takes into account suspended solids in the water and measures the clarity, absorption of light and the amount of light which gets scattered causing little to no glare to houses on the banks of the river. The topography of Newbold is mainly flat with a couple of gentle slopes, which consists of grass land, bare ground and the remainder of the area been surrounded by trees. As the majority of the days throughout the year are sunny with little or no overcast shadows. This means that there is an abundant amount of sunlight which hits the pasture and bare ground with the majority of the amount of sunlight been absorbed with small amounts uv-rays that bounce off and create minimal to no discomfort to the eyes. Pretoria in South Africa is geographically the same in essence as Newbold Crossing in NSW as the same phenomena with glare occurs there. Clarence Way, Newbold NSW 2460 http://maps. google. com. au/maps? hl=en&tab=wl Natural and artificial methods of lighting Ndebele houses in Pretoria, South Africa only had one opening which was the entrance into the house. As displayed in the picture below the entrance was typically facing the south, this meant that minimal amount of light entered the building. The source of light came from a fire which was set in the middle of the hut. Image 1 Ndebele traditional huts Traditional houses in Pretoria, South Africa have always aimed at eliminating the maximum amount of sunlight that could penetrate their huts. But through the years their huts have evolved and changed due to the influences that they had from the Sotho and Pedi neighbours. In respect to the dimensions of the entrance of their huts, they have gotten bigger meaning that further light could enter the building. This concept is similar to houses first built in Newbold Crossing. Initially they had small window dimensions, as they thought this would minimise the amount of heat that would enter the building, but they suffered from cold nights and low levels of lighting in houses. Soon they developed a new concept where they would have larger window dimensions to allow light into a house so that rooms would be illuminated, and so that relatively low amount of heat would be retained within the household for the cold night, making houses thermally more comfortable. This same concept lead to the idea of large windows been incorporated into Newbold Crossing. The concept has developed as houses in this region have solar passive design. The houses constructed have specific eave dimensions to counteract the amount of sunlight the building takes in. In the winter the sun has a low angle in respect to the horizon of the earth, and the maximum amount of sunlight is absorbed to maintain the building warm and well lit up. But in the summer the angle at which the sun is in respect to the horizon to the earth is greater, this is where the eaves are used to counteract the effect of direct sunlight by the building. To further avoid the abundant amount of direct sunlight, properties in Newbold have trees located in-front of large windows. In the centre and other areas of a house that sunlight does not reach, a skylight is put in place to aid with natural lighting and avoid carbon footprints. The artificial method of lighting in Newbold is through incandescent light bulbs and some of the newer houses use halogen downlights. But the Clarence Valley Council (corresponding council of Newbold) has set up initiatives and emphasised the use of compact fluorescent lights which have less wattage ower but in turn does not require the same amount of energy to run, therefore it uses less electricity and minimises carbon footprints. Taking in mind that there is plenty of sunlight throughout the whole year into households, so artificial lighting should only be used during the evening or for tasks that are complex and require good lighting.

Charles Babbage s Analytical Engine - 1154 Words

In 1842, Ada Lovelace learned that Charles Baggage had given a series of lectures on his Analytical Engine. Luigi Federico Menabrea had written up the lectures in the French work, Sketch of Charles Babbage’s Analytical Engine. Though Babbage would never build the Analytical Engine, its concept was groundbreaking for the time. It was essentially the first idea for a programmable computer. Ada was so fascinated with the topic that she decided to translate the work into English. Babbage was impressed with her work and asked her â€Å"why she had not herself written an original paper on a subject which she is so intimately acquainted† (du Preez 108). At the time, women rarely were able to publish original work. They were usually forced to do as Ada did, merely translate the work of men. Ada successfully managed to circumvent this obstacle by adding a series of notes to Babbage’s original text. Her notes ended up being three times as long as the original, and even cor rected many of the mistakes that Babbage had made. He noted that in doing so Ada was able to â€Å"enter fully into almost all the very difficult and abstract questions connected with the subject† (du Preez 108). These notes laid out the concept of computer programming and the required elements for a computer language. Unfortunately, Ada was still required to use a pseudonym, her initials A.A.L, in order to get the notes published in journals.
