Employment Law in Hungary Problem Question

Employment Law in Hungary Problem Question The difficulties that Andreas and Luka face in this circumstance relate to the fact that where Treaty Articles[1] and Regulations[2] are directly applicable in national courts. Directives are only binding as to the result to be achieved, with it being necessary for the Member State to adopt the national law in such a way as to implement the Directives terms.[3] This means that whilst Andreas and Luka would have been able to rely directly on a Treaty Article or Regulations to enforce their EU rights in the Hungarian courts, they must rely on some alternative method of enforcement in respect of the Directive. It is these alternative methods of enforcement that lie at the crux of the issues here. Although the direct effect for Treaty Articles was not instant, it was developed over a period of time, and Van Gend was the first judgment to expressly state that Treaty Articles could be directly effective.[4] On the other hand, Article 288 TFEU[5] specifically says that Regulations are directly effective. This was confirmed in Leonesio [6] and held that Directives are only directly effective in respect of the aims to be achieved and that the Member States are given discretion as to how these aims are introduced into national law. On the face of it, it could be suggested that because Directives are not directly enforceable in the national courts, Member States would be able to disregard the requirements of the Directive. If as it has happened in this circumstance, it does not suit the current national requirements. This would, of course, make Directives largely irrelevant. This was the view that was taken by the European Court of Justice (ECJ) in Van Duyn v Home Office.[7] In this judgment, it would be held that, if the Directive was clear, precise and unconditional (the same requirements as exist for the direct effect of Treaty Articles and Regulations)[8], and had a direct effect on the relations between individuals and the Member States. Therefore, the Directive ought to be given direct effect in the national courts. The above position was further clarified in Pubblico Ministero v Ratti.[9] Mr. Ratti was a manufacturer of solvents in Italy, was charged failure to comply with the stricter Italian law. The ECJ made clear that the proper purpose of direct effect for Directives was to prevent a Member State from gaining an advantage by ignoring the requirements of a Directive. In essence, a Member State is estopped from denying an individuals rights based on the contents of a Directive once the period for implementing the Directive has passed. Based on the above, it seems that Andreas and Lukas position is a relatively strong one, but unfortunately, the issue is slightly more complicated. These complications are initially lie in the fact that a failure to implement a Directive into national law is entirely caused by the fault of a Member State. In Marshal,[10] it was recognized that allowing an individual to rely on the provisions of a Directive directly against another individual could have unfair results. This is because the individual expected to comply with the Directives may have no idea of its existence. On this basis, it was further held in Faccini Dori v Recreb[11] that the Directives could only have a direct effect on the Member State itself. This is known as a vertical direct effect. This is clearly a limiting factor and therefore it is essential that it is possible to identify what kind of organization fits within this requirement. The issue of identifying against whom the direct of a Directive could be relied upon was addressed in Foster v British Gas.[12]Here, it was held that an organization would be part of the Member State if it was subject to the authority or control of the State, or had powers that went beyond those that ordinarily exist between individuals. There are two separate approaches that are followed in this respect. In Sozialhifeverband,[13] it was held that private companies owned by a local authority would be considered sufficiently linked to the State purely based on the nature of their ownership. In Vassallo, [14] it was stated that the nature of the role of the organization could also impact on whether it was considered part of the State. In this case, a privately-run hospital was considered part of the State. This is because some of its activities were publicly funded and partly also because it was serving a public function. It can be seen from the above, the fact that Directives can only have a vertical direct effect will have a significant impact upon Andreas and Lukas ability to rely on the Directive. It seems probable that even though Andreass employer receives some of its funding from private contributions, the fact that it is partly funded by the State, and it will be considered to serve a public function. It will mean that it will be considered part of the State and that, Andreas will be able to rely on the provisions of the Directive directly against it. The effect of this will ensure that prior to his dismissal, Andreas will be considered to have held a permanent contract. Therefore, he will presumably be able to rely on Hungarian employment law, at the very least, attempt to assert that he should receive some compensation for his dismissal. However, Andreas will not be able to assert that the Directive means that he should not have been dismissed. This is because the only relevant purpose of th e Directive is to ensure that a permanent contract is granted after two temporary ones have elapsed. The position is very different for Luka. This is because the company for which she is working with is purely privately owned and funded. This is unlikely to be considered to serve as a public function. Therefore, she will not be able to rely on the direct effect of the Directive. However, this is not the end of the matter, because there are further possibilities that may assist her. The first of these possibilities lies in what is known as an indirect effect. In Von Colson Kamann,[15] it was held that national courts have a duty to interpret national legislation in line with EU provisions if this was possible. The approach in Von Colson Kamann[16] was quite limiting in that it only applied to national legislation that was implementing the Directive in question. This approach would not assist Luka, this is because there is no indication that the Hungarian government has taken any implementing steps at all with the regards to this Directive. The position was expanded somewhat in Marleasing[17], that to require national courts to interpret all national legislation in line with EU provisions where possible. It is not possible to comment on the impact of an indirect effect on Lukas position specifically. This is because this will entirely depend on whether there is already in existence any Hungarian legislation that could be interpreted in line with the provisions of the Directive. If this is possible, Luka will be able to rely on the existing national legislation and the Hungarian courts will be required to interpret accordingly. Clearly, if there is no relevant Hungarian legislation exists, of if the existing legislation is written in such a way that an alternative interpretation is not possible, the indirect effect will be of no assistance to Luka. The second possible solution for Luka can be found in the judgment in Francovich.[18] In this judgment, it was held that where a Member State has failed to implement a Directive and if certain other requirements are satisfied, an individual would be able to hold the Member State liable for their losses. In order for State liability to arise, three conditions must be met. Firstly, the Directive must grant rights to the individual. Secondly, it must be possible to identify these rights from the content of the Directive. Finally, there must a direct causal link between the Member States failure to implement the Directive and the loss suffered by the individual. There seems little difficulty in applying the above three conditions to Lukas position. On the fact given, it appears that the very purpose of the Directive was to grant individuals with the right to be placed on a permanent contract and the subsequent employment security that such a contract provides. It is also clear that the nature of the Directive makes its purpose clear. The position in respect of the causal link between the failure to implement the terms of the Directive and the loss sustained by Luka is an interesting one. This is because, taken at a simple level, the non-renewal of Lukas contract would not have occurred if the Directive had been properly implemented. Luka would already have been working under a permanent contract. However, the failure to implement is not necessarily the reason for Lukas loss. This is the downturn in piano manufacture and the subsequent loss of her job. In this respect, Luka may have lost her job even if she had a permanent contract. In order to address this, it would be necessary to consider the steps taken by Kende Pianos in deciding whom to dismiss. However, it seems that even if it is possible to demonstrate that Luka would have been dismissed anyway, even if she would be on a permanent contract. Therefore, on the fact that she will not receive this payment is directly caused by the failure in implementation of the Directive and Luka should be able to claim damages from the State in order to compensate for this loss. In conclusion, Andreas will be able to rely on the Directive directly in the Hungarian courts to ensure that he receives the same employment rights as an individual on a permanent contract. On the other hand, Luka will not be able to rely on the direct effect of the Directive, but she may be able to rely on its indirect effect, or she may be able to seek damages from the Hungarian State.

FIR Filter Design

The objective of this project is to use three different design methods to design a low-pass filter that meets specifications given, and then compare these three different methods through different parameters. In this project, seven filters should be designed using Matlab. And we compare them on worst case gain, largest tap weight coefficient, maximal passband and stopband error, magnitude frequency response, impulse response, group delay and zeros/poles location. Finally, use these filters to do filtering, and then compare their responses to the predicted one. Discussion of Results: > Part 1: Window Method (a) Use fir1 function to synthesize an FIR that meets specifications using a boxcar window. Worst gain = 1.8372 Largest tap weight coefficient = 0.3694 Maximal passband error = 0.1678 Maximal stopband error = 0.0795 (b) Use Hann window to synthesize an FIR that meets specifications. Worst gain = 1.4154 Largest tap weight coefficient = 0.3496 Maximal passband error = 0.0052 Maximal stopband error = 0.2385 **Filter #1 is the unwindowed design, and Filter #2 is the windowed design. From the comparison above, we can see that the unwindowed design has a more critical passband and stopband edge, but the windowed one has a smaller maximal passband error as we expected. Also, the windowed one has a larger attenuation on stopband than the unwindowed one. The group delay responses of two designs are the same. (c) Use Kaiser window to synthesize an FIR that meets specifications Worst gain = 1.6900 Largest tap weight coefficient = 0.3500 N = 21 (which is in 20 in matlab) Maximal passband error = 0.0706 Maximal stopband error = 0.0852 ** Filter #1 is the unwindowed design, and Filter #2 is the kaiser design. From the comparison above, we can see that both designs have critical passband and stopband edges, but the kaiser one has a smaller maximal passband error as we expected. Also, the kaiser one has a smaller attenuation on stopband compare with the unwindowed one. The group delay responses of two designs are different, the Kaiser one only has 20th order, so the group delay is 10, not 11 as the unwindowed one. (d)The zeros of the three windowed designs ** Filter #1 is the â€Å"boxcar† design, and Filter #2 is the Hann design, Filter #3 is the Kaiser design. From figure above, we can see that Hann design has a zero far from unit circle, which is corresponding to the slower attenuation compared to the other two designs. The zeros of â€Å"boxcar† design are similar to the Kaiser design. > Part 2: LMS Method (a) Using Matlab's firls function to meet the original design specification. Worst gain = 1.5990 Largest tap weight coefficient = 0.3477 Maximal passband error = 0.0403 Maximal stopband error = 0.1137 ** Filter #1 is the 2(a) design, and Filter #2 is the â€Å"boxcar† design. From the comparison above, we can see that the â€Å"boxcar† design has a more critical passband and stopband edge, but the LMS one has a smaller maximal passband error as we expected. Also, the LMS one has a larger attenuation on stopband than the â€Å"boxcar† one. The group delay responses of two designs are the same. (b) Using Matlab's fircls1 function to meet the original design specification. Worst gain = 1.6771 Largest tap weight coefficient = 0.3464 Maximal passband error = 0.0516 Maximal stopband error = 0.0782 ** Filter #1 is the 2(a) design, and Filter #2 is the 2(b) design. From the comparison above, we can see that the 2(b) design has a more critical passband and stopband edge, but the 2(a) one has a smaller maximal passband error. Also, the 2(a) one has a larger attenuation on stopband than the 2(b) one. The group delay responses of two designs are the same. (c)The zeros of the two LMS designs ** Filter #1 is the 2(a) design, and Filter #2 is the 2(b) design. From figure above, we can see that 2(b) design has a zero far from unit circle, which is corresponding to the slower attenuation compared to the other design. The zeros around the unit circle are similar to each other. > Part 3: Equiripple Method (a) Using Matlab's firgr function to meet the original design specification (uniform error weight) Worst gain = 1.6646 Largest tap weight coefficient = 0.3500 Maximal passband error = 0.0538 Maximal stopband error = 0.0538 ** Filter #1 is the 3(a) design, and Filter #2 is the â€Å"boxcar† design. From the comparison above, we can see that the â€Å"boxcar† design has a more critical passband and stopband edge, but the 3(a) one has a smaller maximal passband error. Also, the â€Å"boxcar† one has a larger attenuation on stopband than the 3(a) one. The group delay responses of two designs are the same. (b) Using Matlab's firpm function to meet the original design specification Worst gain = 1.6639 Largest tap weight coefficient = 0.3476 Maximal passband error = 0.0638 Maximal stopband error = 0.0594 ** Filter #1 is the 3(a) design, and Filter #2 is the 3(b) design. From the comparison above, we can see that the 3(b) design has a more critical passband and stopband edge. And the stopband error is 0.0488 (which is consistent with 0.0538*(1-20%)=0.04304), the passband error is 0.0639 (which is consistent with 0.0538/(1-20%)=0.06725). The group delay responses of two designs are the same. (c) The zeros of the two equiripple designs ** Filter #1 is the 3(a) design, and Filter #2 is the 3(b) design. From figure above, we can see that 3(a) design has a zero far from unit circle, which is corresponding to the slower attenuation compared to the other design (almost no attenuation on the figure shown ). There is only one zero stays outside the unit circle for 3(b) design, which is the minimum phase design. > Part 4: Testing (a)Table the features for the 7 designed FIRs: Features Filter #1 Filter #2 Filter #3 Filter #4 Filter #5 Filter #6 Filter #7 Maximum gain 1.8372 1.4154 1.6900 1.5990 1.6771 1.6646 1.6639 Maximum passband linear 0.1678 0.0052 0.0706 0.0403 0.0516 0.0538 0.0638 Maximum passband error(dB) -15.5052 -45.7568 -23.0266 -27.8855 -25.7472 -25.3838 -23.9007 Maximum stopband linear 0.0795 0.2385 0.0852 0.1137 0.0782 0.0538 0.0594 Maximum stopband error(dB) -21.9886 -12.4495 -21.3913 -18.8858 -22.1339 -25.3838 -24.5274 Group delay 11 11 10 11 11 11 11 Largest tap weight coefficient 0.3694 0.3496 0.3500 0.3477 0.3464 0.3500 0.3476 (b) From the figure followed, we can figure out that the group delay is 22-11=11 samples regardless of the input frequency. (c) Compare the original, mirror, and complement FIR's impulse, magnitude frequency, and group delay response **Filter #1 is the original filter, Filter #2 is the mirror filter, and Filter #3 is the complement filter. (d) Maximal output is 1.8372, which equals to the worst gain prediction of this filter. > Part 5: Run-time Architecture (a) N = 8, M=1; N = 12, M=1; N = 16, M=1; Round off error N=8 N=12 N=16 From the comparison above, we can see clearly that as the value of N increases, the round-off error decreases. Bits of precision is N-1-1=N-2 (b) Choose two 12-bit address space which has memory cycle time of 12 ns, so the maximum run-time filter speed is 1/ (12ns/cycle*16 bits) =1/ (192 ns/filter cycle) =5.21*106 filter cycles/sec > Part 6: Experimentation (a) The maximal of the output time-series is 1.1341. It is reasonable, because it is smaller than the worst case gain which is 1.8372. So this agrees with the predicted filter response. (b) The â€Å"chirp† function makes a short, high-pitched sound, and it sounds four times, which is corresponding to the 4*fs. When all the .wav files are played, we can hear obviously that the frequency of output sound is much lower than the frequency of input sound, which means that the filter did filter high-frequency components out. From the figure above, we can see the high-frequency components are gone, which agrees with the predicted filter response, a low-pass filter. Summary: Through this project, the detailed processes of designing a filter by three different methods have been understood. And we know more about all the parameters which would affect properties of the filters, and how to use different methods to design them and make best trade-off between each other.

Chemotherapy

Chemotherapy Cancer ,which is also called Malignant tumors ,it controll cell growth and proliferation mechanism disorder caused by the disease. also it will invade the surrounding normal tissues even through circulating system or the lymphatic system is transferred to the rest of your body. Now people more and more early to have cancer, Many things can let us more easy to increase the risk of cancer, there are including smoke, certain infections, radiation, lack of physical activity, obesity, and environmental pollutants.These can directly damage genes or combine with existing genetic faults within cells to cause the disease. Chemotherapy is one of the methods for the treatment of cancer. That uses drugs to destroy cancer cells. It is also called â€Å"chemo. † Today, there are many different kinds of chemotherapy. So the way patient feel during treatment may be very different from someone else. Why I chosen this treatment, because Chemotherapy is a common treatment that I usu ally heard in news or someone talk about it, so I also interested in this treatment.Chemotherapy can be used to: Destroy cancer cells,Stop cancer cells to spread ,Slow the growth of cancer cells. Chemotherapy can be given alone or with other treatments to cure. It also can help other treatments work better. For example, you may get chemotherapy before or after surgery or radiation therapy. Or you may get chemotherapy before a peripheral blood stem cell transplant. can be given in these forms: an IV (intravenously),a shot (injection) into a muscle or other part of your body,a pill or a liquid that you swallow, a cream that is rubbed on your skin.But chemotherapy have many disadvantage, this treatment will hurt your body and let your body become weak. Because chemotherapy have poor selectivity on cancer cells, it have a toxic effect on the cancer cells and normal cells. Besides it can kill the cancer cells, at the same time it is obvious damage the organ function and normal tissue cel ls. Chemotherapy common side effects: 1) Myelosuppression: Most chemotherapy drugs can cause Myelosuppression , and it shows for the decline in white blood cells and platelets, fraudulent claims red fine chest, even like hemoglobin decreased. 2) gastrointestinal reactionLoss of appetite, eating less,feel sick, vomiting, abdominal distension, abdominal pain, diarrhea or constipation. 3) Cardiac toxicity Some chemotherapy drugs can produce cardiac toxicity, damage to myocardial cells, palpitation, palpitations, chest tightness, precordial discomfort, shortness of breath and other symptoms, even it will heart failure. 4) liver damage Patients with liver discomfort, and even can cause toxic hepatitis. 5) kidney damage Cause renal dysfunction and low back pain, kidney discomfort. 6) Phlebophlogosis The vascular lesions Color become dark red or dark yellow, localized pain. ) Toxicity of the nervous system Mainly refers to the chemotherapy drugs produce damaging effects on the surrounding nerve endings, the patient may appear extremities numb extremities sensation. 8) Anaphylaxis Many cytotoxic drugs will cause varying degrees of allergy. I think’s disadvantage was more than advantage, and this treatment will hurt our body, in my opinion for patients who has poor health, poor liver and kidney function, low white blood cells, and malnutrition, in addition to rescue type chemotherapy. I don’t think chemtherapy was a good idea to treat cancer.And people who has Terminal cancer do not use the way of Chemotherapy, maybe you don’t do anything can let you stay in world for more time. Chemotherapy will make you miserable. So health is precious! We have to keep our body more and more health, stay away from cancer. http://wenku. baidu. com/view/faecdb80d0d233d4b14e6985. html http://wenku. baidu. com/view/a33d7a65caaedd3383c4d3c6. html http://www. cancer. gov/cancertopics/types/alphalist http://translate. google. com. hk/translate? act=url&hl=zh-CN&ie=UTF8& prev=_t&sl=en&tl=zh-CN&u=http://www. cancer. gov/cancertopics/types/alphalist

Civil War And Its Greatest Moral, Constitutional, And...

Lincoln is one of the â€Å"champions† of human life and dignity. He is one of the presidents in the US. Lincoln led the United States through its Civil War—its bloodiest war and its greatest moral, constitutional, and political crisis. In doing so, he preserved the Union, abolished slavery, strengthened the federal government, and modernized the economy.By the 1850s, slavery was still legal in the southern United States, but had been generally outlawed in the northern states, including Illinois, whose original 1818 Constitution forbade slavery, as required by the Northwest Ordinance. Lincoln disapproved of slavery, and the spread of slavery to new U.S. territory in the west. On October 16, 1854, in his Peoria Speech, Lincoln declared his†¦show more content†¦Sandford; Chief Justice Roger B. Taney opined that blacks were not citizens, and derived no rights from the Constitution. Lincoln denounced the decision, alleging it was the product of a conspiracy of Demo crats to support the Slave Power. Lincoln argued that the authors of the Declaration of Independence never intended to say all were equal in color, size, intellect, moral developments, or social capacity , but they did consider all men created equal—equal in certain inalienable rights, among which are life, liberty, and the pursuit of happiness .After the state Republican party convention nominated him for the U.S. Senate in 1858, Lincoln delivered his House Divided Speech, drawing on Mark 3:25. He said that ahouse divided against it couldn’t stand. The speech created an evocative image of the danger of disunion caused by the slavery debate, and rallied Republicans across the North. The stage was then set for the campaign for statewide election of the Illinois legislature, which would, in turn, select Lincoln or Douglas as its U.S. senator.On November 6, 1860, Lincoln was elected the 16th president of the United States, beating Democrat Stephen A. Douglas, John C. Br eckinridge of the Southern Democrats, and John Bell of the new Constitutional Union Party. He was the first president from the Republican Party. As Lincoln s election became evident, secessionists made clear their intent to leave the Union before he took office the
