Law of Digital Evidence - Essay Example Additionally, computers are known to save some files irrespective of the user having deleted them or considered them eliminated from the device. Such observations allow for the complicating the entire process of promoting a search warrant on these devices. It further suggests that computer devices may not be classified along the regards or presentation of general warrants. It also implies that the interest of attributing computer searches to a different set of warrants acknowledges their unique qualities (Jarrett and Bailie, 100-114). Computers are general hubs of extremely personal information. They are considered to host information that defines individuals in a wholesome manner. They, further, have customized safety measures to allow for the protection of the contained information. Such attributes allow for the reflection of the personal nature of the information hosted or stored in these devices. Additionally, computers are utilized extensively in the expression of their users. Such is achieved via the extensive programs that are installed in these devices. The observations map these devices as rather unique to be subjected to the plain view of a search warrant (Jarrett and Bailie, 112). The decision over the approach that is considered to affect the respective computer devices remain advised by the nature of the information that aspires to be extracted. Apparently, search warrants are developed to in anticipation of the information to be established. Such observations regarding the particulars of these searches allows them to be regarded as rather exceptional from routine searches. The concern is further complicated by the elemental superiority associated to computers, especially on user security. Additionally, computers remain regarded as the best exemplification of personal space. The implication of these thoughts proposes the enforcement of a search warrant on these devices. However, the warrant should not be regarded or spelt under the

Features of bluetooth technology Essay Example for Free

Features of bluetooth technology Essay The logo for Bluetooth is based on Runes surrounding the legend of Harald Bluetooth. Bluetooth the technology is based on communications central to man’s own personal space. Fundamentally Bluetooth operates within the Industrial, Scientific and Medical (ISM) band at 2. 4 GHz. It is a short-range wireless communication standard defined as cable replacement for a Personal Area Network (PAN) (see â€Å"Bluetooth†. Grolier Encyclopedia of Knowledge, pp. 87-94). Figure 1 is the Bluetooth Logo. A cable replacement standard has been defined because cables limit mobility of the consumer; they are cumbersome to carry around, are easily lost or broken. Often connectors are prone to difficult to diagnose failures; or are proprietary. To counteract these limitations Bluetooth is designed to be light and portable. It can be embedded to take the riggers of physical knocks and shocks. It includes standards and protocols to make it mobile, robust, reliable and not limited to one manufacturer (see â€Å"Bluetooth†. Grolier Encyclopedia of Knowledge, pp. 87-94). The operating band also fits the goals of Bluetooth, imposing requirements as a cable replacement. The cost needs to be comparable with cable. Reductions can be achieved by operating in the licence free 2. 4 GHz ISM band, keeping backward compatibility wherever possible lowers the cost of ownership by avoiding upgrades and having a relaxed radio specification enables single chip integrated circuit solutions. It also needs to be as reliable and resilient as cable and cope with errors and degradation caused by interference. For mobile devices it must be compact, lightweight, low power and easy to use (see â€Å"Bluetooth†. Grolier Encyclopedia of Knowledge, pp. 87-94). A. 1 Frequency Hopping We have addressed the reasons for the Bluetooth without delving into the ‘nuts and bolts’ of the technology to discover how it operates. For the majority of countries the ISM band used by Bluetooth is available from 2. 40-2. 4835 GHz, although some countries impose restrictions. In this band Bluetooth uses Frequency Hopping Spread Spectrum (FHSS) techniques in order to improve its immunity from interference (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). In unrestricted countries the radios hop in pseudo random sequences around all available channels, this equates to 79 RF channels with a channel spacing of 1 MHz. Starting at a base frequency of 2402 MHz then the frequency of the channels, f, can be expressed as: f =2402 + n MHz where, n, is the channel number with an integer value in the range of 0 to 78. In restricted countries a limited frequency hopping schemes with just 23 channels is used and is catered for in the Bluetooth specification. Both hopping schemes have a 1 MHz channel spacing making it possible to design a simple radio interface whereby the baseband only has to specify a channel number and the radio multiplies this up to the appropriate frequency offset (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). In this FHSS scheme there are 1600 hops per second, which is a hop every 625  µs. Part of this hop timing is taken up by the guard time of 220  µs allowing the synthesizer time to settle. The frequency hopping implements time division multiplexing as shown in Figure 2. The basis of the scheme has the Master device transmitting in the first 625 us slot, k, and here the Slave receives. In the next slot k = 1 the Slave is permitted to transmit and the master listens (see J.Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). Figure 2: Frequency Hopping, master and slave interact on corresponding slots The radio must be able to retune and stabilise on a new frequency within tight time constraints. This is pushed further when establishing a connection; the hop rate can be shortened to every 312. 5 us. As the radios are constantly hopping to different radio channels, this ensures that packets affected by interference on one channel can be retransmitted on a different frequency channel. To further enhance resilience both ARQ (Automatic Repeat reQuest) and FEC (Forward Error Correction) form part of the specification (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall). One drawback with the normal hop sequence is the time taken for production testing. Bluetooth ensures adequate frequency coverage with a test sequence allowing the radios to be tested at a faster rate (see J. Bray and C. F. Sturman, Bluetooth: Connect Without Cables†, Prentice Hall).

Hinduism Origins :: essays research papers

The origins of the Hindu religion can be traced back to the year 5000 BCE. The word Hindu is a very old word. In ancient times, the river Indus was called â€Å"Hindu† by the Persians who had migrated there. They also called the land Hindustan and it’s inhabitants, Hindus. After that, the religion that followed was called Hinduism. Hinduism is also referred to by practitioners as Sanatana Dharma. This means â€Å"the eternal faith†. Hinduism is not strictly a religion. More than a religion, it is a way of life. Hinduism has no founder, Anyone who practices Dharma can call himself a Hindu. Hinduism is based on the practice of Dharma, which is the code of life. Hinduism has been their way of life for many years. Scholars are confused, it seems to be that Hinduism has no founder. Has been traced to about the year 5000 BCE to the Indus Valley civilization. Development of Hinduism influenced throughout the years by many invasions. Biggest invasion is believed to be the Aryan invasion, circa 1500 BCE. Aryans were light-skinned nomadic people from the steppes of Russia and Central Asia. When they invaded India, they brought with them religion of Vedism. Beliefs mixed with more advanced beliefs of the Indians, creating Hinduism. Early Vedism was the early earth and life changing belief that the battle loving tribes needed. lso believed that Hinduism is derived from Animism. Animism is the belief that every thing and person has a powerful spirit in them or a soul. This spirit is supposed to be capable of helping or harming human beings. This faith is very popular. In fact, if an animist were to want to cut down a tree, he would first explain to the tree how it will be used and then asks for permission to cut it down. That is why many people like the North American Indians used every part of the animal that they killed. During the tTime of the invasions many things changed. The Rig-Veda was composed during the early beginnings of the Hindu religion. The Rig-Veda is a collection of 1, 280 hymns to the gods. There are also three other collections, which were added later. They are called the Samaveda, the Yajurveda and the Atharvaveda. Between the years 800 and 600 BC, a body of style writings called the Brahmanans was attached the Vedas. These writings contain explanations of the ceremonies mentioned in the Vedas.

Beowulf: Movie or Poem? Essay

Before watching the Beowulf movie, I had the opportunity to read the poem along with ghthe class. I thought the movie was going to be a slight different from the epic poem, but that it was still going to stick to the message that the poem had given us. As we started to watch the movie, I noticed that I as completely wrong because the movie is almost completely different from the epic poem. The movie kept very few elements from the original epic poem. In the poem, Grendel attacks Heorot because he is a descendent of Cain that has been exiled into darkness. The movie let us know that Grendel was the son of Hrothgar, the king. Grendel could not attack or go against God himself, so he took it against God’s followers. In the movie, Grendel attacked Heorot because he cannot stand music and singing. Noise really bothered his head and ears. In both the movie and poem, Beowulf fights Grendel without any kind of weapons or armor because Grendel isn’t using any of that either. Beowulf wants it to be a fair fight. Beowulf tears Grendel’s arm off and hangs it up; I think to symbolize the victory. Another major difference to me, is that in the poem, Beowulf kills Grendel’s mother as soon as possible, while in the movie somehow Beowulf is seduced by her. Beowulf never kills Grendel’s mother. I think the movie producers took a really big leap in this part, it went completely different from the epic poem. Grendel’s mother is also described as a lizard-type of creature that was unappealing and unattractive. Completely opposite to the epic poem, Grendel’s mother was provocative and seductive in the movie, maybe this is the reason why Beowulf gives in to her. As a result of this matter, Beowulf becomes the father of a dragon. The epic poem never mentions about Beowulf becoming a father, he was always loyal and faithful to his wife. Finally in the poem, Beowulf returns to his homeland, where he became old  and became king. Beowulf had to fight the dragon along with his knights working as a team, but instead, the knights had given up and weren’t helping him at all. Wiglaf is the only person who reaches out and helps him fight the dragon. This signifies that the Anglo-Saxon Era was coming to an end. Despite all of this, Beowulf never gives up, he fights to the end. In the movie, Beowulf never returns to his homeland, instead he becomes king of the Danes as a result of Hrothgar’s suicide. Beowulf ends up killing the dragon in both versions, but in the movie, Beowulf seemed to have lost the heroic, fearless, and courageous values. Beowulf just seemed like he had given up. Maybe it was culpability about all his lies that had finally got to him. I enjoyed reading the poem much better than watching the movie. I think the movie- producers shouldn’t have taken so much out of the original poem. They made Beowulf seem like a completely different person. The original Beowulf poem portrayed many of the Anglo-Saxon values, while in the movie, it just seemed like they didn’t portray any of them at all. I wanted to see Beowulf just like they portrayed him in the poem. I wanted to see Beowulf being an honorable and heroic figure that never gave up on it’s people.

Problem Analysis Contract Law

An offer must be firm and demonstrate clear intent, whereas an acceptance must accept the term of the offer unqualifiedly. It should be noted that in the usual case, communication of acceptance and consideration are also essential to constitute a valid acceptance. If all elements are found to exist, the contract will be complete, and Lain will be bound to fulfill his promise. Offer The first issue to address is whether an offer exists. Lain would presumably argue that his statement was merely a puff and lacked intention to be acted upon as he announced it impulsively under the influence of alcohol, and the offer does not give him any benefit.This is, however, a weak argument. The general rule is that the intention of the parties should be assessed objectively, as in Smith v Hughes (1871) LORD 6 CB 597 where Blackburn] stated that the promises conduct should be considered in a way that appears to a reasonable man. The phrase â€Å"would pay El 0,000† exhibits both certainty and intention, because it has stated the exact amount of reward and the wordings shows immediate readiness to be bound. His claim is particularly convincing given his wealth. A reasonable man would therefore believe that Lain did intend to pay the reward if the stated condition was fulfilled.Similar to Williams v Cowardice (1833) 5 Car & P 566, there is only a promise made by one party. Lanai's statement appears to represent a unilateral offer that would be converted into a binding contract once the required act has been performed. This would be further discussed in the following. Acceptance In unilateral contracts, performance of the stipulated act constitutes the acceptance of offer (Cargill v carbonic smoke gall co. [1893] 1 CB 256 (CA)). Both crews have performed the act of â€Å"crossing the finish line† ahead of Lanai's yacht.However, it is highlighted that the current case differs from Cargill v Carbonic Smoke Ball Co. In that it is arguable whether or not anyone who has completed the performance can claim the reward. On one hand, it can be said that since Lanai's offer does not state any conditions, crossing the finishing line is sufficient in itself. This argument is, however, suggesting that any random yacht that happens to cross the finish line by incident is also entitled to the reward, which makes little sense. The court is more likely to accept that only qualified competitors who crossed the knish line ahead of Lanai's yacht should be considered.This is indeed supported by the fact that the crew of † Moon Amour† joined the competition upon knowing the offer. It shows that the offered also understands that being a qualified competitor is a prerequisite. By entering the race, both crews have agreed to the Race Rules and therefore, they should be bound by such rules. In Clarke v Dungaree [1 897] AC 59, the court stated that when the party understands that the race is to be run under a particular set of regulations, and that he delibe rately enter for the race upon those terms, he is bound by such rules.Whilst the crew of â€Å"Bell Raider', being a qualified competitor, had fulfilled the conditions of Lanai's offer, since the French crew was not officially recognized by the race officials due to a breach of the Race Rules, it can hardly be said that the latter has validly accepted Lanai's offer. Communication of acceptance Whilst communication of acceptance is needed in the usual case, in unilateral contract, the offer showed by his language and from the nature of the contract that he waived the need to communicate (Cargill v Carbonic Smoke Ball Co. ).Whether Lain received notice of the performance is irrelevant to the matter at hand. Consideration The agreement has to be supported by consideration in a legally enforceable contract. To determine if there is consideration, it brings up the debate of whether reliance is essential. Lord Dunedin, in Dunlop Pneumatic Tree Co. Ltd v Selfridges & Co. Ltd [191 5] AC 84 7, 855 defined consideration as â€Å"an act or forbearance of one party, or the promise thereof, is the price for which the promise of the other is brought, and the promise thus given for value is enforceable†.Following his definition, obviously, both crews' act Of crossing the finish line, in return for the reward, is treated as good consideration. The answer would be less certain if reliance is required. In the book The Law of Contract, Triple asserts that an act or forbearance would not be consideration â€Å"where the promises would have accomplished the act or forbearance anyway†. This view was supported by R v Clarke (1927) 40 CLC 227, where the court held that the claimant could not recover the reward because his concern was not the reward when he gave the information.In other words, the claimant had not â€Å"act in reliance upon† the offer. It is a matter of debate if this prevailing view is in fact erroneous, as argued by Paul Mitchell and John Philip s in â€Å"Is reliance essential? † , but this is not the current concern. Assuming that this general view is still correct, the French crew's acceptance was clearly motivated by the offer as they did not intend to participate in the race until Lain ‘s announcement. But in the case of â€Å"Bell Raider†, there is insufficient information to tell if their crew did act in reliance to the offer.There may be three different situations depends on the facts. Firstly, if the situation is identical to that of the French crew, they act in reliance to the offer for the same reason. Secondly, if evidence shows that â€Å"Bell Raider will join and win the match even without Lanai's offer, their performance cannot be regarded as consideration as there is no reliance. Thirdly, if â€Å"Bell Raider† will join the match but not necessarily reach the destination ahead of Lanai's yacht, it can still be argued that the reward motivated the crew to outperform themselves and thus, there is reliance.
