The delay for a single user, that is allocated a single slot, transmitting over a Rayleigh fading channel was evaluated using the configuration of Fig. 2 cumulative distribution func- tions (CDF’s) of the number of frames, by which each bit was delayed, were evaluated for 2 10 frames, with of 0.6, 0.7, and 0.8, average channel SNR’s of 10, 20, 30, 40, and 50 dB, normalized Doppler frequencies of 0.0042, 0.025, 0.054, 0.079, and 0.133, and for both the BER optimized speech and the BER optimized computer data transmission switching SNR’s of Table I in the absence of interference. It should be noted that during this evaluation of latency there was no limit imposed upon the buffer length. However, in Section VII-B, where adaptive modulation is compared to fixed schemes, the buffer is limited to the maximum allowed speech-specific and memory-constrained data latency. Fig. 3(a) and (b) are examples of such delay CDF’s, expressed in terms of the number of 4.615-ms frames for , for various normalized Doppler frequencies and for our speech and data schemes, respectively.
Next, we examined if topical application of Tat-Rac1 protein can promote wound healing in vivo. Based on clinical practice, diabetic wounds represent a common type of unhealed wound in humans, therefore, we generated wounds in db/db mice. Excisional wounds were made with a 6-mm diameter biopsy punch on the dorsal skin of 8-10 wks old db/db mice (both males and females). Gender- matched mice were divided into two groups for Tat-Rac1 protein (in10µl PBS) or equal volume of PBS-vehicle treatment, topically applied onto the wound area, starting immediately after punch biopsy (day 1). Based on in vitro experiments (Figure 2) showing the effective dose is likely in the µg range, we tested three doses of Tat-Rac1 (0.5, 1 and 2 µ g/wound, daily). While 0.5µg/wound had modest effects, 2µg/wound had no effect on promoting healing (not shown). We therefore focused on a1 µ g/wound dose for the remaining studies. With Tat-Rac1 treatment, accelerated wound closure was observed beginning on day 4 after wounding compared with PBS treatment (Figure 3A, B). Tat-Rac1-treated db/db mice wounds were completely closed by day 13, whereas PBS treated wounds show slower healing for all time points. Histologically, Tat-Rac1 treated wounds were smaller in width and had longer epithelial migrating tongues by day 6 and day 8 compared to PBS controls (Figure 3C, D). On day 13, Tat-Rac1-treated mice had smaller stromal areas in the wound than untreated control mice (Fig 3C). By staining wounded tissue with V5 antibody, Tat-Rac1 protein was detected in epidermal keratinocytes and stromal cells in the wound area (Figure 3E). We also performed western blot analysis using a V5 antibody to confirm the presence of Tat-Rac1 protein on day 8 wounds (Figure 3F).
RT) -1 , of 6 Gbps. Even though these ER and data rate represent a significant improvement over the 1.3 dB and 4 Gbps performance achieved using the first version of the modulator , 6 Gbps is not limited by the new waveguide modulator itself since the intrinsic bandwidth (RC cutoff) is above 10 GHz. Further analysis reveals two causes for the 6 Gbps bandwidth limit. First, the wirebond inductance (estimated to be 0.7 nH) chokes the high-frequency components of the capacitor charge/discharge current pulses (LC cutoff frequency is ~3.9 GHz). Second, the driver circuitry has a limited slew rate and was, in fact, expected to deliver 8 Gbps performance under nominal operating conditions. To test this assertion that the
ing, the Lange coupler   , and tandem type     have been uti- lized. However, complicated multilayered circuitry is necessary due to these coupled structures’ narrow line widths and narrow gaps between coupled lines. Further, to design the coupling between 3.0 and 6.0 dB, a crossover connection between the output arms may be needed for the planar rat-race hybrid . Fortunately, the branch line coupler can easily achieve the tight coupling using planar structures. The conventional branch-line coupler employs four quarter wavelength ( λ 4 ) transmission lines. Generally good performance and 90˚ phase shift between the coupled port and the through port are obtained in the narrow within the vicinity of center frequency. The branch line coupler can be realized using planar transmission line, artificial transmission line  and no- nuniform trans-mission line , but both of the artificial and nonuniform transmission lines are difficult in fabrications. A branch line coupler using the lumped-element with asymmetrical E-equivalent sections was described at  for bandwidth enhancement, but the lumped element S- parameters was varied at higher frequency. A compact 3 dB branch-line coupler using substrate integrated suspended line (SISL) technology was proposed in , but it had a lot of com- plexity due to multilayer fabrication process. In , a miniaturization of the conventional branch line coupler was done by adding open stub to the series and parallel transmission line of the conventional 3 dB coupler. Although such de- sign gives a better performance, it suffers from the decrease in the operating bandwidth. The same idea was used with replacing the traditional λ 4 lines with multi-T-shaped lines , but multi-T shaped lines affected the phase difference between the two output ports. Another method without lumped components or DGS structure is applied to realize the miniaturization of branch-line coupler. Firstly, a novel center-symmetrical spiral-interdigital resonator (CSSIR) was presented, then a miniaturized branch-line coupler, which was with the CSSIR unit cells embedded into the branch and parallel lines, was designed . The overall operating bandwidth is small due to spiral interdigital resonators. A branch line coupler with a wide passband, utilizing multi sectional idea is given in . The overall size of such coupler is very large and can be nearly mini- mized using the defected ground structure under the vertical branches. In this article, a new idea of reconfigurable 3 6dB branch line coupler is proposed, where it uses only a simple open and short circuit at branch line coupler edges to develop 3 dB or 6dB branch line coupler.
The influence of additive background noise in a handsfree communication system degrades the quality of the transmitted speech signal. The main purpose of speech enhancement is to reduce the noise while keeping the speech undistorted as much as possible. Noise reduction is useful in many applications such as speech communication and automatic speech recognition where efficient noise reduction techniques are required. The most widely used approach to estimate the priori SNR parameter is the decision-directed (DD) method. Estimation of DD Priori SNR of current frame follows the shape of the estimated DD priori SNR with a frame delay i.e. previous frame and instantaneous SNR of current frame. DD method was presented in , and modified DD (MDD) method is proposed in . The TSNR method is able to suppress the delay and reverberation effect while maintaining the benefits of the DD method. TSNR method was presented in ,,,, and modified TSNR (MTSNR) is proposed in ,. The improved signal obtained by the TSNR technique presented still suffers from distortions. The distorted signal is processed to create a fully harmonic signal where all the missing harmonics are regenerated. Hence, this method is called as Harmonic Regeneration Noise Reduction (HRNR) method and it was presented in ,,,.
Now total cost = 2*5+3*2+1*6+4*7+1*2+2*12=76, which has been reduced further by 5 units. This also the basic feasible solution obtained by VAM. Now we will check the optimality of this solution. As we have two rows and one column with 2 assignments we can choose any one of them
to that of the Lv-NC and Lv-shNC groups. However, Lv- shUfm1 pretreatment markedly attenuated urinary protein excretion in db/db mice, whereas Lv-Ufm1 showed the opposite effects (P<0.01, Figure 9A). Moreover, renal structures and the in ﬂ ammatory response were examined by H&E staining and immunohistochemistry, respectively. As shown in Figure 9B, the kidneys of untreated db/db mice showed obvious glomerular epithelial hyperplasia and tub- ular dilatation. In the mice treated with Lv-shUfm1 and Lv- Ufm1, the pathological scores were markedly decreased and increased, respectively (P<0.01, Figure 9B). Interestingly, we noticed that de ﬁ ciency in Ufm1 by Lv- shUfm1 led to reduced macrophage in ﬁ ltration (P<0.01, Figure 9C). As shown in Figure 9A – C, diabetes-induced myocardial damage and myocardial in ﬂ ammation in db/db mice were almost completely abrogated in Ufm1 knock- down mice compared to those of the control group (P<0.01). Similarly, there was a higher cardiac index, obvious cardiomyocyte hypertrophy and more macrophage in ﬁ ltration in the db/db mice than in the control group. Furthermore, in the mice treated with Lv-shUfm1 and Lv- Ufm1, the cardiac index, cardiomyocyte hypertrophy and macrophage in ﬁ ltration were markedly decreased and increased, respectively (P<0.01, Figure 10A – C).
Each of the categories security and costs has been as- signed 4 points. Though being also very relevant, conven- ience pales in direct comparison to the latter two (as proved through the examination of relative relevance in ) and thus has been assigned only 3 points. The two functionality requirements execution of a bank transfer possible and payment of amounts < 20 ct possible con- tribute little to the acceptance of the procedure. They are assigned 1 point in order to round off the evaluation. The aggregation of the named criteria with their assigned point values results in the evaluation matrix depicted in table 5. MP procedures can be assessed and ranked ac- cording to their achieved overall score.
3) The idle channel noise is measured at the electrical reference point in the frequency range between 100 Hz and 4 kHz. The measurement requires a time window which starts exactly at the end of the activation signal. Any "ringing" of filters or receivers or reverberance influence shall be taken into account, the time window must be shifted accordingly. The length for the time window is 1 second, which is the averaging time for the idle channel noise. The test laboratory has to ensure that the terminal is activated during the measurement. If the terminal is deactivated during the measurement, the measurement window has to be cut to the duration while the terminal remains activated.
[L]ocal government and local democracy deals with local issues and needs – they cannot all be taken into care in the centres of power – that is part of democratic participation. . . . We have regional and local government [which] is there to organize people locally in order to inform people and to execute state policies locally; to take a leadership in making sure that policies fit the local needs and benefit various circumstances; it is also there to pass on information on the local needs and problems of the people to the state level; communication channel between people and government. [In turn,] [n]on-governmental organizations (NGO) are there to help the people to participate in implementing both - the state policies as well as local initiatives on grass-root level. The duty of the people, the citizens themselves is then to look out for themselves and to take initiative – it is your right as a citizen to be part of decision-making process in your country by for instance choosing the local representatives. At the same time it is also your responsibility to contribute at least to the development of your own community; this is why local participation is so important, you may not be able to affect directly the country wide policies or solve the issue of poverty or education as a whole, but you can improve your local surroundings (ibid, 25-6; emphases in original).
In this study 6 maturity models are presented. These are: MM1: “A Maturity Model for accessing Industry 4.0 readiness and maturity of manufacturing enterprises” by Schuhmacher et al. is a MM that was published in 2016. It concentrates on the manufacturing industry and has maturity levels as well as maturity dimensions. The dimensions that are presented are Strategy, Leadership, Customers, Products, Operations, Culture, People, Governance and Technology. These dimensions were then further split into sub-dimensions called maturity items. The maturity levels are split up in 5 levels based on a Likert- scale where the first level presents the absence of any Industry 4.0 capability and the fifth the full implementation of Industry 4.0 capabilities. Furthermore they entitled every of their dimensions and their sub-dimensions to a specific weight. These weights are then used in connection with the maturity level of the sub- dimension/ dimension in order to create an overall score of maturity. In Figure 1 the formula for calculating the maturity level can be found.

Ideally, when the same sample is imaged numerous times, the same response would be measured each time. As exemplified in figure #3, there is an average 20% variation between replications. All things being equal, looking at the transducer variation above, one would expect the variation here to be 6%. But in this case, we see an extra 14% variation. This may have been caused by different couplings of the samples between the transducers, transducer misalignment, or variation of pressure applied to the samples. During the measurement process, i assumed that that carrot was in a constant state. Realistically, it is reasonable to suggest that slight changes cou have occurred within the carrot. For instance, the sample imaged near the end of the trial was in the jar substantially longer than the sample imaged near the beginning. This gives the last sample more of an opportunity to absorb the water around it. What this means that the frequency response of a sample could vary to some degr with time. This research data was not analyzed in this respect, so this factor is not accounted for. Needless to say the majority of the variation was likely due to problems with transducer alignment and coupling.
